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

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

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.

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

When the drum is at rest. at the end of a
complete revolution, the holes in gear lie will

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.

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

number of castellations in flange 4t and in collar

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

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:

of the next operation the arm 208i continues its

these arms between these pins also prevents the
register from overthrowing an extra number.

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.

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
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

retarded on leaving engagement on the upward

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
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
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

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

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

present invention the desired effect is more sim

(two in this case) for imparting the motion.

' The above described movements of the arms

50 the gear segments and gears, but also brings the
registerwheels back into necessary alignment to
enable the locking devices (when the postage

55 correct reading’of the ñgures, and what is also of
importance, the retracting, or moving back, of the
pawls inside the tens wheel.
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.
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
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
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.
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.
