The base carries the envelope sealing mechanism and irn pression roller, and can bemounted on any suit able support. 'I‘he portable unit B contains the printing dies and registering mechanism and can he detached from the base and carried to a. post omce to have the register “charged” with an amount of prepaid postage. Unit B and base A 10 are provided with mechanisms, 'as described in said patent, which when the unit is properly mounted on the base renders the machine as a whole operative, but will prevent operation there of, or of the printing mechanism, or register, when the- unit B isvseparated from the base. Pivoted on the base is a frame H2 containing an impression roller and means for moistening the ñap >of the envelope. The impression roller is driven from the printing drum actuating 20 shaft. When the base and portable unit are properly assembled the impression roller is di rectly under the printing drum i6 and an en velope passing between them will receive an im print from a stamp die on the drum. ñap downward, from left to right (Fig. 1) over the frame H2 until its leading end is slightly between the impression roller and drum_ IE. lI‘hen lever 22 is pressed with the thumb to move shaft 22a out of the way of crank 2l and the latter is then turned one revolution, being then arrested by the end of shaft 22a which should be released as soon as crank 2l has passed it. This movement of crank 2l causes the printing drum l@ to revolve once; and in so doing the dies will‘ 10 be inked and shortly before they reach the print ing point the envelope will be gripped between the drum and revolving roller and, if but one stamp is to be-printed thereon, will be forwarded through and delivered onto the table or any suit able receiver at the right of the machine. Dur ing such passage thedies make an imprint on the-face of the envelope, ‘the ñap of the envelope is moistened, and in passing between the drum and roller will be caused to adhere to the en velope as described in our; aforesaid patent. If it is necessary to make two or more stamp impressions on the envelope to place the proper u amount of postage thereon, the envelope is stopped immediately after the first imprint has 25 The printing drum been made thereon, and is held in such position At the front of unit B (Figs. 1-3) is a housing while the printing drum completes its revolution; within which is a revolvable drum i6 mounted then the drum is againrevolved and when the 30 upon an actuating shaft 6. Said drum carries a stamp die Il again arrives at the printing point post marking die I8, )and stamp die il.

Die i1 is provided with a revolvable print ing wheel lla bearing on 'its rim the various 35 money values or stamp denominations. When the printing drum is turned in a counter clock wise direction the stamp die il willfbe moved 40 past the printing point (i. e. opposite the impres sion roller) just in advance of the postmark die. 'Ihe‘drum shaft 6 has one bearing in the front The stamp selecting devices A rod 23 extends axially through the shaft 5 35 and drum I6 and projects through an opening in the cover plate Za of the drum housing (Fig. 3), and has a knob 23a on its front end. 'I‘he rear end of rod 23 is supported in a ñxed bracket ' Ic of the casing, and another in a member 6c of _member ¿le and carries a castellated collar 23t a bracket il (see Fig. 3). On the front end of which is adapted to engage an opposed castel- ' shaft 6 ,within housing 2 is a ñange Ga to which lated flange ¿it on member de. The member ‘le ^ the printing drum I6 is attached. >0n the rear ' is preferably made detachable for convenience in assembling. A revolvable face cam 26 is mounted end of shaft 6 is a spiral gear 8, a thrust bear ing 8a being interposed between said gear 8 and . on rod 23 between gear 8 and member de and bearing member 4c. Gear 8 meshes with a spiral has a sleeve hub 26a mounted in a fixed bracket ` gear 'l (Figs. 1-3) on a drive shaft 5, which can member 4d. be revolved by a hand crank 2l; o_r other suitable means. Adjacent shaft 5 is a shaft 22a (Figs. 1-3) one end of which normally projects through .wall lb and acts as a stop for crank 2l. Shaft 22a is normally moved outward by a coiled spring 22s interposed between a collar 22h on the rod and the bracket 4, the outward movement of the Yshaft being limited by a stop collar 22e carrying a pin 22d which engages a cam slot 22t in a curved plate 22e fastened to the wall Ib. . _On the outer end of shaft 22a is a lever 22 (Figs. 1-2) which can be moved by the thumb of the operator’s hand when operating crank 2|; and when shaft 22a. is thus turned the pin 22d 65 The denomination printing wheel lla. (Figs. 1-4) is mounted on a shaft Hb in drum i6, and on the outer end of shaft Hb is fastened a gear 50 llc which meshes with a similar gear iße, having its hub revolvably supported in an axial bore in the drum, rod 23 extending through said hub. Gear iB_e has a series of holes isz (one for each denomination engraved on wheel ila) through 55 it, equally spaced around its axis. A disk 23h is fastened to rod 23 opposite gear 46e and has a series of projecting pins 23e spaced similar to the holes in the gear Hic which they 00 are designed to enter. A spring 23s interposed between the gear IEe and disk 23h normally sep engaging cam slot 22t will cause the shaft to arates them and also forces the rod 23 to nor-'_ move inwardly and withdraw out of the path oi’ mally remain in its outermost position and holds `_ crank 2i, which can then be turned; When - the castellated collar 23t in engagement with crank 2l has passed shaft 22a lever 22 is released ' ñange 4t. and shaft 22a is moved outward by spring 22s _ into position to stop the crank 2l at the end of the revolution of shaft 5. ' In this machine the printing drum is revolved once for every stamp printed in order to bring the dies into contact with the inker to prepare them for printing; and to actuate mechanism which registers the value of the stamp printed. In operating the machine an envelope is slid, In the body of the hub of the drum I6 (Figs. 3-4a) and in alignment with the holes' in the gear H_Ee, are a circular series of holes iGf in which are tumbler pins 21 (Fig. 4a) . These pins 70 are normally projected by springs 22s, so that their extreme outer ends will be ñush with the outer surface of gear iâe (see Figs. 3-4a). The pins 2ï will lock the gear l6e to the drum i6, and as gears ite and ilo are in mesh, the de 75 2,124,888 In the machine shown two counters or regis i'la may be revolved as a unit but their relative tering mechanisms are employed, one of them positions can only be altered by moving gear Ile relatively to the drum. The tumbler pins 21 are preferably constructed and arranged to operate substantially as described in our'afore registering in ascending order the total of the values of all stamps printed; the other subtract -ing these values from the amount of prepaid postage for which it was originally set by a post ' ofilce oillcial. 'I'he means for setting the sub tracting counter and for locking the mechanism when this predetermined amount has been ex hausted has been described in our prior patents and need no further description here. When the drum is at rest. at the end of a complete revolution, the holes in gear lie will be in alignment with the pins 23e of disk 23h (see Figs. 3, 4, 4a). Then by pushing knob 23a inward the rod 23, disk 23h and stop collar 23t will be moved inward, thereby disengaging col lar 23t from flange 4t; and causing pins 23c Both counters are mounted in a frame having two end walls 200a and- 200b with a middle wall 200e between and as the lcounters are of identical to enter the holes in gear l0e and displace the tumbler pins 21; and then rod 23 with all parts fastened to it may be revolved. When rod 23 is turned gear I0e will turn the denomination 20 wheel i1. Thus any desired value engraved thereon can be brought to operative position. design the description of one will explain both. Each register shown is in general of the well known geared type in which the excess of ten in any denomination wheel is transferred to the 20 wheel of next higher denomination by means of “Geneva” gears. In our invention however theregisters essentially differ from the standard con structions in that both the “units” wheels, and the “tens” wheels are independently operated, ' When the desired selection has Vbeen made knob 23a is released and spring 23s will return rod 23 to its normal position, vwithdrawing pins 23e 25 from gear i0e and uncoupling gear lie from the shaft. and pins 21 will lock the gear to the drum so that comparatively high values may be quickly ' registered without imparting the usual extent of movement to the units wheel. ' and thus lock the denomination wheel l1 in the position to which it was previouslyy adjusted rela tive to the drum, and sto'p collar 23t will re 30 engage ilange 4t and prevent further turning of rod 23. » As shown in Figs. 9 and 10 the units wheel 20| is made fast to a shaft 20|a journaled in the « walls 200a and 200e and has a driving gear wheel 2Mb on its outer end. A. second shaft 202e in axiall alignment with shaft 20Ia has one end journaled in wall 200b and has a driving gear 202e fastened on its outer end. The opposite end ' The spacing of the pieces on the rod 23 (Fig. 3) is such that the stop collar 23t will not be disengaged from flange It Vuntil the coupling of the »gear lie to the shaft is completed, so ' Lso 3 The registering mechanism nomination wheel l'la will also be locked to the drum; and when so locked the drum and wheel said patent. y of said shaft 202e is supported by a'disc 2022: that the knob 23a cannot be turned without also turning the denomination wheel. The »lands and - which forms a part of the tens wheel structure ` spaces of the castellated stop collar 231,L and flange 4t are such that engagement of the two can only take place at points in the circle cor responding to the points where the holes in gear loosely mounted a gear wheel 203, having a cy iindrical projection or hub.203a, and a flange IGe will register with-the tumbler pins 21. The number of castellations in flange 4t and in collar 23t are equal to the number of values engraved on denomination wheel i‘la, and the rod 23 may be located in any desired angular position by first pushing the knob 23a,l inward to disengage collar 23t fromv flange It-then turning it to the division desired, and then allowing the collar to re-engage the ñange. The selection of dies can be made only at a time when the drum is in its normal position of rest; and in order to prevent accidental opera tion of the handle 2i at the time the selection is being made shaft_22a is prevented from moving inward during the die selecting operation by 20|, clearly shown in Fig. ‘l4._ On» shaft 20la adjacent the wall 200e is 203D (Fig. 14). On the shaft 202e adjacent the flange 20311 are formed or fixedly secured two similarly spaced ñanges 2021i. Loosely mounted on the shaft adjacent the outermost of these flanges 20217 is a disc 202x, and attached to or formed integral with this disc is a cylindrical shell 202, the end of which opposite the disc 202:1: has a rotative ñt on the periphery of the gear 203 as shown in Figs. l0 and 14. The shell 202 has a bearing on the hub of the gear wheel 203. Said 'shell 202 encloses both the flanged portions 202b of the shaft 202e and hub of wheel 203, and is provided with ten internal ratchet teeth 2021,L (Figs. 12', 13 and 14) designed to be engaged by pawls 203c. In the groove between the flange 20319 and the body of the wheel 203 are mounted means of a lever 20 (Fig.- 3) which is pivoted . two spring actuated pawls 203e which are adapt at 20a. to a member of the bracketÀ.

The gears‘20iu and 205t are respectively fastened to sleeves 206u and 20$t (Fig. 10) revolvably mount ed on a supporting shaft 28 (Figs. 1 and 5). 'I‘he small denomination is to be registered, therefore the carrier 32a will be so shifted that the proper segmental-gear 32 thereon will be brought into position to mesh >with the units pinion 20m and motion would be transmitted from this gear 35 through sleeve 206e and gear` 205u to the gear 2Mb operating the units wheel of the counter as sleeves are respectively provided l with pinions above described, and the pinion 20`|t would not 20w and 20‘it which are 'adapted4 to be engaged `be engaged nor operated by the gear segments. 40 with mutilated Vgear segments 32 (one for each If however a stamp of denomination of ten or ~denomination of stamp) (Fig. 5) which are more is to be printed then the carrier 32a would mounted on a slidable carrier 32a keyed to the main shaft 5 (Fig. 1).

When the machine isl at rest the iiat ends of pawls 202e (Figs. 12, 13) are not seated against the side of the ratchet teeth-or notches- 202i, but arms are withdrawn. _ ' ' 25 The movement of the arms 20811 and 208t in' approaching the home position during their de scent is retarded by means of the cams 209 and 209m to avoid the building up of dangerous mo are withdrawn a slight angular distance up the 35 sides of 202i. This is to lensure that the ends of pawls will ynot be‘resting on the high points of 202t. As these pawls are shown in the present Figs. 12, 13, their flat ends are resting against 202i. This has been termed “neutral” position, but the pawls do not stop there. The cams 209 and 209:0 are fastened to the main shaft 5, and are substantially identical as are the arms 20811. and 208i the only difference being in the shape of the cam faces 208193: (Fig. 45 6) on their ends. Both arms descend at the same time and engage the pins 20511 and 205m: ontheir respective gears 20511 and 205i whether it has been driving its side of the counter or not. These arms 208t and 20811 are designed to (1) stop any tendency the gear wheels 205t and 20511 50 may have to move beyond the point to which they are positively driven, (2) to alternately slightly advance and retract said gears, the advancement of the gears 20511. being- eiîected to advance and 55 retract the pawl 203e only when a transfer is effected by the Geneva gear wheel 20411 how ever, and (3) when withdrawing from. the pins to leave the gears in a slightly retracted position in order to insure an open path for the ñrst tooth of the gear segments 32 coming into mesh with the pinion 20111 or 201i ‘at the next opera tion of the machine. - The action of the arm 20811 operating the units side diiîers from the above only in the sequence because 2081211: of arm 208i is between pins 205cm, having entered between them on the previous operation just as the last tooth of gear segment - In the case of the arm 208t operating -on the tens side of the counter, as shown in Figs. 15-18, 65 the cam end 208bn: is arranged to stop the gear 205t as in Fig.4 15, then retract said gear as in Fig. 16, and here the mechanism is stopped, it being the end of an operation or the home posi tion. 'I'his retracting movement of the gear 205t 70 will cause the pawls 202e to be withdrawn from the full line position of Fig. 12 to the dot and dash line position and will occur on each machine cycle of operation._ Thus, when the sleeve 202 is mentum in the tens wheel 202; and they are also retarded on leaving engagement on the upward move to prevent gear 20511, orI 205i from racing. As a further preventive brakes 2in may also be applied to the shafts 20111l and 2021i of both counters, as shown in Figs. 9 and 10. As previously stated the tens wheel is inter mittently driven from the units wheelby means of the Geneva gear 2040, one step for each rev olution of the units wheel to thereby effect a tens transfer. Therefore it will be obvious that this is the only time that the pawls 203C become -eiîective in rotating the tens wheel or shell 202 and that only at this time will the action of the arm 20811 have any effect with regard to the con trol of position or rectification of the pawls 202e. The rectifying movement as caused by the opera tion of the arm 20Bt however, is effective on each 30 35 40 45 cycle of operation. To understand more clearly why there is a re versal of movement of the pawls 202C and 203e as 50' effected by the cam portions of the arms 208i and 20811, the combined action of the two arms will be described. . Assuming that the units wheel has just com pleted its movement through the ten position and that the transfer was made through the Geneva drive gear .20411, both arms 208i and 20811 will have moved simultaneously to the initial stop ping positions shown in Figs. 15 and 19. From these positions the arm 208i will move down 60 ward to a position which will cause the pawls 202e to be retracted to their dot and dash line posi tion, Fig. l2, while the arm 20811. will move down ward to a position which will cause the pawls 203e to advance and thereby advance the tens 65 wheel 202 slightly.` The pawls 202C which had been rocking freely about ñxed axes while the ratchet teeth moved thereover duringthe drive of the tens wheel 202 by the pawls 203e', will thus be spaced ay suilicient distance away from the ratchet teeth, with which they should next en gage, to thereby prevent the said pawls 202e from resting upon the top of said ratchet teeth or being ' rotated by the pawls 203c, which are associated in a position to engage the wrong ratchet teeth 75 ' on the next operation if the drive is next taken 75 with vthe units Geneva transfer, in a manner aiaases through the pawls 262e. in other wordsthe pos sibility of this error is rectiñed. The opposite or advance movement which is clear of the pins ‘itâ and 295e. The driven tens wheel must then be advanced far' enough to ensure the dropping in of the tens pawl 262e, and this given to the pawls w3c by means of the cam pcr- - action must be independent of and supplementary - tion of the arm 2632i is particularly provided to to the normal drive. It would suñice if pawl âüâc 5 ensure the completion of rotation of the Geneva was operated to 'normally drive the tens wheel gear 205e so that the wide tooth portion on said beyond the normal stopping point and was then Geneva gear, Fig. ,9, will fully clear the tooth retracted to a position slightly bach of such point. space on the periphery of the unit wheel 2m. In our mechanism, however, both the pawls are 10 VIn a postage meter machine of this type it is _ _advanced and retracted, one motion being the re 10 important that this clearance be ensured. The verse of the other. The advance and retraction reason being that this Geneva gear 25:50. is mount of the units drive naturally affects the relative ed (loosely) on the same rod as the other Geneva gears of the register. In order to reset the de scending, or substracting, register _when the meter locks out, it is necessary to rock all oi the Gen eva gears _clear of the numeral wheels. When the> register locks out at the time the unitsv Geneva gear V20411 has just completed a transfer 20 to the tens wheel, its. wide tooth must be fully clear of the tooth space on the unit wheel, other wise the Geneva‘g'ears cannot be rocked out for resetting., ' - _ v Upon movement of the arms 2B8t and 29811, from the latter position which is the home position, as .in Figs. 16 and 20, the rectifying action is oon 'tinued still further before the commencement of another registering operation. ' During 4this fur ther movement to the positions of Figs. 1'? and 21, 30 thegpawls 292e and 203e are caused to move in positions of the ratchet teeth and the actuating pawl âiàîc at the positions mentioned above. At all other times the effect is interrupted because 15 the relatedGeneva is at rest on‘the rim of the units wheel. This double action is desirable in this type of mechanism for the necessary align ment _of the number wheels for locmng, setting ~ and reading. Although in this instance the sup 29 plementary motion is imparted to the pawls them selves, obviously the sameeiïect might be obtained by the advancement of the tens number wheel itself by another entirely separatemeans. In the present invention the desired effect is more sim ply obtained by utilizing the normal gear drives _ (two in this case) for imparting the motion. It is obvious that the ratchet drive can be applied to other wheels in the register if desired, the opposite directions and opposite to the direc tions just described, that is, the pawls Zßìowill in case higher values than those registered by op erating the tens wheel were t0 be Printed and registered at one operation of the machine.

We mean thereby to include any two ‘ . _ ' The above described movements of the arms ' 208t and 2|l8uA not only ensures the meshing of 50 the gear segments and gears, but also brings the registerwheels back into necessary alignment to enable the locking devices (when the postage amountis exhausted) to operate, for correct set - ting up of the wheels in the post oilice and for 55 correct reading’of the ñgures, and what is also of importance, the retracting, or moving back, of the pawls inside the tens wheel. _ Y _ In actual use of these machines the operator - turns'the crank handle quickly and the number 60 wheels and their driving gears whirl very rapidly, necessitating the mechanical safeguards incor porated in the mechanism. ’As the- units wheels only operates the tens wheel when it is transferring its full count of 10 to said tens wheel, therefore there are only two positions when the supplementary motion from the units wheel cam lever 20811. can be transmitted to the gear v2|l3.- One is when the units wheel vhas stopped so that the two` half teeth on its rim are 70 just about to engage a tooth of the related Geneva gear, the other is when the units wheel has stopped so ~that the two half teeth have just left a tooth of said Geneva gear, but are still practically in contact with it. While the transfer is actually being made the cam lever arms 208i and 2ñ8u are wheels of diiïerent denominations in the register which it may be desired to operate in the manner _ described. Operation e The operation of the machine and several parts " thereof embodying the present invention is here inbefore clœrly set forth. . In brief, when- a stamp `ïof lless value than ten is to be printed the --rod 23 is pushed inward .and then turned until the 60 proper printing stamp on wheel lla is brought to operative position, and this movement of the rod _ will also, through the mechanism described, shift the gear segment carrier so ,that the segment cor responding to the stamp desired is brought into position to mesh with the umts pinion Zilla; then the rod'is released and the parts are operated by turning the crank _2i one revolution during which revolution the stamp is printed on the envelope as ' described, a-nd the units wheel is shifted a num ber of digits corresponding to the value of stamp. The tens wheel however will not then be driven 70 except in event of a carry over from the units wheel to the tens wheel. _ If a stamp of the value of ten or more is to be s 7 printed the rod 23 is pushed inward and turned to adjust the wheel I 1a to bring the proper de nomination printing surface to operative posi tion; and simultaneously carrier 32a is shifted to bring the proper gear segment 32 into position to mesh with the tens pinion 20H; then the rod 23 is released and crank 2i turned one revolution, during which revolution the stamp is printed on the envelope and the tens wheel is actuated the 10 proper extent to register the value of the stamp printed; and during such operation the units wheel remains unaffected. The construction described enables the machine to be readily set in a very simple manner to print 15 any desired value that may be engraved on the value printing wheel I'la; and said wheel can be adjusted to proper position to print the value de sired by simply turningthe rod 23 by means of knob 23a. and such turning of the rod automati 20 cally varies the position of the register operating gear segments so that the register will be actuated either through the units wheel or the tens wheel in accordance with the denomination or value of the stamp printed. 25 By employing one set of gear segments and means whereby the segments can be caused to operate either the units wheel or the tens wheel of the register, the machine is greatly simpliñed, the number of operative parts which would be 30 ordinarily required greatly lessened, and exces sive wear on the units wheel (which ordinarily would be caused by having to transmit all de nominations to be registered through such wheel) is obviated, and the durability and accuracy o! 35 the register enhanced.
