It may be stated, tive relation with a blank plate 42 carried along however, that as disclosed in said patent, the die the forward side of the machine frame by a car actuating rocker arms 18 and 85 are rendered riage 15. The die heads 65 and 66, as herein effective automatically during one rocking cycle shown, are ?xed in vertically spaced relation on of these arms immediately after and as an in ' a rotatable vertical shaft 16, Fig. 1, journaled at cident to the stopping of the die heads in any its lower end in the machine frame 68 and at selected position.‘ its upper end in an upstanding arch-like frame The carriage 15, Fig. 1, upon which the plate element ‘H.

To this end acter‘ on the plate 42 positioned between the the carriage 15 has its main body portion mount selected pair of dies. ed by means of a plurality of guide’ rollers 95, Actuation of the selected pair of dies 65a and 60 Figs. 8 and 10, on a transverse rail or track 96 66a- is preferably effected by means which drive ‘which extends across the front of the frame 11. the two dies toward each other so as to engage The rollers 95 are so related to the track 96 as to permit movement of the carriage across the the plate 42 and form the desired character therein without vertically shifting the plate from ‘the full-line position of Fig. 10. In the form il lustrated this means, for the upper die 65a, com prises an upper rocker arm 18, Fig. 1, pivoted at 19 on the frame element 1'! and operated by a toggle 89, interposed between said arm ‘I8 and an actuating shaft 8| mounted adjacent to the 70 top of the frame element 11. The lower die 66a is actuated by a lower rocker arm 85 which has one end pivoted at 85' to the frame 'I'Lwhile a pitman 86 operated by a crank 81 on a horizontal operating shaft 88 is connect front of the machine during, for example, char acter spacing movement of the carriage, while on the top of the carriage a cross slide 98, Figs. 8 and 10, is provided for movement transversely with respect to the track 96, or toward and away from the die heads. Thus, the cross slide 98 provides for line spacing movement, the plate 42 ‘being supported on the cross slide 98 by releas able clamping means such as the clamping jaws 99, Fig. 10. As shown in Figs. 8 and 10, the jaws 99 are 75 carried on a mounting member I88 which is de 2,405,786 tachably secured to the cross-slide 98 by means described hereinafter, the member I80 having upstanding bearing lugs I?'l thereon in which a jaw-supporting shaft ‘N32 is j'ournaled. The two jaws '99’ and 95", Fig. '10, are in the nature ‘of opposed ‘plates, ‘the lower one 99' of which car ries lugs H13, Fig. 8, through which the shaft 482 rotatably extends, and the upper jaw 99" has a pivotal connection with the iower jaw 99’ .‘by means ‘of pins NM extending loosely ‘through the two plates 99’ and 99". These pins I04 have securing wires 135 extending 'therethrough on the outer sides of the two plates, 99’ and 99" and the pins 10-4 .and these plates are so ?tted as to permit slight pivotal movement for clamping and unclamping ‘of a "printing plate 42. To provide for clamping of the jaws 99, the plates '99’ and 99” extend at their rear ends so as to embrace opposite sides of the shaft M12, and the shaftis flattened on opposite sides there *of 7as shown in Fig. 1-0. ‘Thus when the shaft “12 is rotated in one direction nearly 90° relative to the plates 99" and ‘919" and into. a position like that shown in Fig. 10., the adjacent rear edges-of the plates are separated so as to clamp the forward or outer edges of the plates or jaws upon the printing plate i2. It will be seen in Fig. 1-0 that a substantially U-shaped spring Hit is pro vided ‘adjacent the central pin Hi4 and between the plates as’ and 93” to separate said plates or ijaws to the maximum extent. Preferably the forward cooperates endinof 'pincers the upper fashion jaw with 89” isa hooked ?at portion or ledge on the forward end of the lower jaw $9’ the ?attened portions of the shaft I'M from the jaws 9-8’ and so" :so ‘as to dispose these ‘portions in the position shown in Fig. 10 and since the rounded portions on the shaft then engage the jaws they are forced into tight engagement with the plate. It will be understood that such rock ing movement of the jaws .99 to and from the loading position takes place in the ‘normal use of the machine while the carriage 15 is located at one side of the embossing position. As herein shown the ‘mounting member Ill-0,, Figs. 8 and 10, is secured on the cross slide 98 by means which ‘provides for adjustment of the mounting member parallel to the path of the carriage, and also which provides for adjustment of the mounting member .so that the plate 152 carried thereby is positioned with its axis par ‘allel ‘to said path of the carriage '15.. To this end the top face of the cross slide. 93 has aligned slots H3 and H3’, Fig. 4, formed therein generally parallel to the carriage path, and a 'iixed depend ing jpin H4, Figs. 4 and 8, projects from the mounting member Hi0 into the slot H3. For co operation with the other slot H3’ a pin H4’ is provided which is ?xed eccentrically on a small "disk H5 mounted in the bottom of the member me. By means of a stub shaft 41:5’ Figs. '4 and 3 projecting upwardly through the member ‘Hill, the eccentric :pin lid’ may be shifted so as to adjust the mounting member into the desired parallel relation to the carriage path, and by a lock .nut H5”, Fig. :8, threaded onto the stub shaft i it’, this adjustment may be maintained. A headed screwi?ii', Fig. 10, extends through an aperture ‘i?iW‘in the member HM! and ‘is threaded into the cross slide 98 to :secure "the as shown in Fig. 10. To facilitate accurate posi mounting member Hi0 onto the cross slide 98 and, tioning of the printing plates between the jaws, as shown in Fig. 10., the aperture ‘190" ‘is :some ‘a shoulder till is formed on the lower jaw 95’ what larger than the screw Hill’ so as to permit slightly inwardly of the ‘flat part thereof, thereby affording a ‘stop for limiting insertion of :a print— 40 the desired horizontal adjustment of the mem ber Iii?. ing plate “as 4-2 between the jaws. To afford longitudinal adjustment of the In the operation of the jaws v99 to clamp a to ?rmly clam the printing plate M in position, printing plate t2, the jaws are ?rst rocked toward the operator so as to rest against a loading abut ment 1| \I'Ei formed on the member i023. Such move merit vof the jaws is effected by the shaft #62 which has a 90° rotative lost motion connection with the lower jaw 99', sufficient to enable the shaft I82 to accomplish its jaw-clamping func~ tion in addition to its function in moving the aws 1. between loading ‘and working positions. The de sired .lost motion ‘is attained by means that are shown and described in vmy aforesaid Patent No. 2,265,229. To facilitate the operation of the jaws 39, the shaft 1.62 has a knurled operating diskor mounting member 160, a transverse slot 93', Fig. 4, is formed :in the cross slide ‘58 and a headed screwed”, projecting ‘from the left end of the member i103, Fig. '8, has the lower edge of its a head positioned in the slot '98’. ‘Thus, by ad justment of ~the screw 98" the positioning of ‘the mounting member longitudinally of the direction of movement of the ‘carriage ‘is determined. For the purpose ‘of imparting the desired line spacing movement to the printing plates, the cross slide '93 is normally urged to a retracted position by springs 15', Fig. 110, and is advanced line by line by means of a ratchet mechanism H6, Figs. 4 and 5.. In the form shown, the cross slide .lzn'ob H l on its projecting left end, Fig. 8. When 8 is ‘partially (supported and guided on the car— ‘the jaws $9 have been shifted to their upright or riage 1'5 by a rod I! ll, Figs. 9 and 10, which is loading position the shaft 102 is turned to the secured to the carriage "l5 and is slidab-ly ?tted ‘full extent permitted by its lost-‘motion connec~ “tion so as ‘to thereby present the ?attened sur ~60 in bearing apertures H8 ‘in depending flanges H9 along the ‘front and rear edges of the cross faces thereon to the jaws 99’ and 199” and there by enable the spring let to separate the plate clamping portions of the jaws so as to fully re lease or unclamp the jaws. rIEhe printing plate ‘G2 ‘is then ‘inserted between the jaws 89 which ‘grip the plate sufii'ciently firmly to enable the ‘jaws to be rotated back to their horizontal posi tion shown in Fig. v10 without releasing the plate, 'so‘as'to thereby enable the plate to be carried to slide 98.. ' A rotatable shaft i212, Figs. 15 and 10, is mount ed transversely of the carriage 1'55, and pinions 125 fixed on this shaft mesh with racks :22 formed ‘on depending‘?anges at opposite ends of the cross slide 98. The shaft 126 carries a ratchet wheel I25, Fig. 5, at one end thereof, and this ratchet is ?xed in a rotatively adjustable relation to the its working position. This movement of the jaws 70 shaft I20 through ‘the medium of a non-rotatable collar I26 and two adjusting screws i 21', as ‘shown 'is limited by ‘an abutment pin Hi2 Fig. 10, on the in Figs. ‘6 and '7 of the drawings.

As shown in Fig. 55, the ac 2,405,786 8 tuating pawl I30 is of an inverted U-form and is riage ‘I5 is preferably such as to simplify and co operate in part in attaining a tabulating control pivoted intermediate its ends, at I 32, on one end of a carrier arm I33. The pawl I30 has a tooth I34 at one end thereof and this tooth is urged of the carriage as well as affording a back spac ing movement and such means include a rack I51 into operative engagement with the teeth of the ratchet wheel I25 by a spring I35 extended be tween the pawl I30 and its carrier arm I33. The carrier arm I33 is pivotally mounted on the shaft operatively associated with the carriage, a ratchet and pawl mechanism, and a tabulating disc, and a control shaft I'I0, as fully described in my afore said Patent No. 2,265,229. I20 for rotative movement relative to said shaft, Character spacing is effected automatically so that by rocking said arm from the position of 10 near the end of each embossing operation by suit Fig. 5 in a counterclockwise direction the cross slide 33 may be advanced. The carrier arm I33 is normally urged by a spring I34’ to its normal position as shown in Fig. 5. able means such as that shown and described in Patent No. 1,831,103, patented November 10, 1931.

The extent of movement of the lever I33’ is lim- . . ited by abutment faces I40, Fig. 4, on the pawls I35 and I36 which engage the abutment I40’ on the carriage ‘I5 so that a full stroke of said lever advances the cross slide 98 one line-space. Hav ing been given such a line spacing movement the cross slide is retained in its advanced position by the controlpawl I3I, Fig. 5, which is pivoted on This last-mentioned means is preferably oper able in any position of ‘the rack I51 and the car riage I15, and as herein shown comprises a hori zontally positioned angle bar 230, Figs. 8, 9 and An 10, mounted on the rail 95 for transverse or ver tical shifting movement by the arm 226, and ar ranged, when elevated from its position of Fig. 10, to release the escapement pawl I62 and there by permit free traversing movement of the car riage. To this end the angle bar 230 has a for the carriage beneath the shaft I20 on a pivot pin I 4| and has a tooth I42 operable to engage the ratchet wheel I25. The tooth I42 and the teeth 45 wardly facing channel portion 23I at its left end. of the ratchet wheel are so related that the yield Fig. 8, into which a roller 232, Fig. 10, on the ing force of the springs ‘I5’, Fig‘. 10, tending to rear face of the pawl I 62 projects, and the bar produce return movement of the ratchet wheel 230 is suspended on parallel links 233 from the I25 acts to hold the cooperating teeth in their op rail 96. Thus the bar 230 is maintained in a erative relation and thereby ?xes the cross slide 50 horizontal position at all times and it is of such 98 in the desired position. As shown in Figs. 4 a length that the carriage ‘I5 may be shifted a and 5, the control pawl I3I has a ?nger piece I44 substantial distance to the right, as viewed in by which it may be depressed to disengage the Figs. 1 and 8, while still maintaining the roller pawl I3I from the ratchet wheel I25, and the pawl 234 on the arm 226 beneath the forwardly pro~ I3I also has a tail piece I45 whioh,in the disen 55 jecting ?ange of the bar 230.
