Application filed October 21, 1911. Serial No. 656,054.

To (116 'ljchom it may concern i lie it known that l. l nvssics GRANT TAKE, citizen of the United States. residing at Chattanooga, Tennessee. have invented certainfnew and useful Improvements in Typographs, of which the following is a specitication.

The invention relates to typograph niachines for embossing or impressing letters in metallic plates for use in addressing and n'iailing machinerv.

.One object of the invention is to provide an arrangei'nent of 1. unches, dies, and pres sure IUOCl'IiIIIlSIll therefor whereby the force exerted for making the impressions will be a compressive one in relation to the frame of the machine and parts carried thereby instead of a force tending to separate or tear the machine apart.

Other features of the invention will be clear from the following description, the invention consisting in the features hereinafter described and an-ticularly pointed out in the appended claims.

In the accompanying drawings lfigure 1 is'a central vertical sectional view through the machine embodying the invention; Fig. 2 is a plan view of the machine; Fig. 3 is a side elevation of the entire machine; Fig. -1- is a view of the cam shaft with the parts to be operated thereby; Fig. 5 is a detail .view of the cam shaft alone; Fig. 6 is a side view of one of the compression lovers; Fig.

T a plan view of said lever; Fig. 8 is a side view of a yoke forming part of the operating connection to one of the compres- Sion levers; Fig. 9 a detail view of a cam operated lever for the carriage feed; Fig. 10 is a view of the guard for the hand lever by which the machine is operated.

in these drawings. 1 indicates a die carrier having two sets of dies 2, each set being arranged in an annular series and guided to more vertically through the carrier. each die having a projection or screw 3 bearing upon a plate l in turn niountcd on springs 5 on the carrier so that any die may be operated inde;icndently of the other dies, the spring supported plate 4. yielding for this purpose at the point where the operated die is located, the o 'ierated (lie being returned to its normal position by the spring plate. The carrier is mounted to rotate on a shaft or tube 6, the upper and lower ends of which are connected respectively with the main frame 8. The carrier has thereon a gear wheel 9 meshing with a gear 10 on a shaft 11 which is driven through bevel gearing 12 from a knob or handle 13 on a shaft 1 1 suitably mounted in the frame. The shaft ll. has at its upper end a suitable indicator so that the operator, by bringing any desired. letter on this indicator to a certain point, can make the corresponding dies reg 'ister with upper and lower punches 15 and 16 mounted to slide vertically in the bracket 8 and in the base 7 of the frame, respectively. Each of these punches is held normally retracted by a spring 17. The upper punch is operated by a lever 18 having a hearing at 19 on the bracket, and having at its other end an adjustable screw threaded studbearingpn the upper end of the punch At an intermediate point on this lever, and closer to the punch than to the bearing 19, connection is made pivotally with an operating rod 20 which extends down through the hollow shaft 01' tube 6, the lower end of this rod being pivotally connected with a yoke 21 which is operated by a cam A on the cam shaft a, suitable antifriction bearings being interposed bet-ween the cam A and the yoke, as shown in Fig. 4. lly this connection the compression lever 18 is operated to force the punch 15 downwardly, and thus to operate the die which is directly under this punch. punch 16 is operated by a lever 22 which has its fulcrum on a roller 23 hearing up against the frame, as shown in Fig. 1, the intcrn'iediatc portion of this lever being in engagement with cams B, B, on the shaft (1, one of these cams being located on each side of the central cam A and the lever 22 beiu bifurcated, as shown in Fig. 7. The free end of this lever is provided with a socket having an anti-friction ball 24 therein, this ball bearing up against the lower end of the plunger 16. It will be observed that the point at which the force or pressure from the cam is applied tothe lever 22 is nearer to the point of work than it is to the fulcrum 23, and this is also true of the upper lever 18.

It will now be seen that in the operation of the parts, when the punches 15 and 16 are forced toward each other to cause the dies to engage the plate to emboss the same,

The lower.

v 1 toward the center line of the machine,

the upper lever 18 is drawn down and the lower lever 22 is moved upwardly, and thus the pressure takes place in directions toward the center of the machine, and the strain is thus a. compressive one instead of a separating one or one tending to tear the frame apart. In other words, the upper lever presses on a fulcrum and exerts its straig the lower lever presses up ag'i'inst its fnlcrum ortoward the center line of the machine. Furthermore, it will be seen that the fulcrum of each lever is considerably removed from the point where the power is applied and the work done, which latter are close together and near the end of the lever opposite to the fulcrum, so that a comparatively small portion of the strain put upon the compression levers is transmitted to the frame of the machine. The lower lever has interposed between it and the cams B, B, an anti-friction bearing shown in Fig. 4. Because of the use of the cam for operating the lower lever, said lever must have a slight longitudinal motion of about one-sixteenth of an inch. This is taken care of by the anti-friction roller 23 before described, and hy'the anti-friction ball 2 The left hand ends of the'lower lever are notched so as to retain the anti friction roller in proper position. The yoke 21 also has slight movement under the action of thecaln A, and to permit this it is pivoted to the lower end of the operating rod 20. The ball 24. rests upon an adjusting screw 25, and by this screw and the upper screw passing through the lever 18, the punches may be adjusted, and then the screws may be held by the jam nuts shown. The centers of the two cams or eccentrics A, B, are located equidistant on opposite sides of'the center of the cam shaft, and in line with the'said center, so that the rotation of the cams or eccentric shaft in either direction causes the eccentrics to transmit opposite motions to their respective levers. The eccentric shaft has a movement of about one quarter'of a revolution, and it is oper ated by a hand lever 26 at the right hand end of the machine. hen the machine is at rest, the center of the larger eccentric A is in the same horizontal line with the center of the eccentric shaft, while the center of the smaller eccentric B, B, is in the same horizontal line, and in front of the center of the eccentric shaft, and thus when the eccentric shaft is rotated 90, the center eccentric or cam A transmits adownward motion to the yoke 22, and at the same time B, B, transmit an upward the eccentrics motion .to the lower lever 22, it being understood that the downward movement of the yoke 21 effects the downward movement of the upper lever 18. feeding the carrier The mechanism for for the blank is also 'tirely free to be operated from the cam or eccentric'shaft a. The carrier presents the blank to the space in between the dies at X. This carrier is not shown in the present case, and may be of any suitable kind. It is operated through suitable connection on a shaft28 mounted in the frame, the lower end of this shaft having fixed thereon a ratchet wheel 29 engaged by a pawl 30- ivote'd to a pawl plate 31 which is m'ounted to turn about the shaft 28 and is operated. through a link 32 from a lever 33 having a'roller 3 t acted on by the cam 35 on the cam or eccentric shaft a. A spring 36 attached to this lever and to a point on the frame of the machine gives the pawl its effective stroke, the action of the cam being to retract the pawl through the connections described. In this retracting action of the pawl it is moved back until the point thereof has passed one tooth of the ratchet wheel, and until it has reached the point of the second tooth. Then as the cam or eccentric shaft is being returned to its original position, the cam moves away from the cam lever 33, andthe spring 36, drawing upon the cam lever and link 32, moves the pawl in the'opposite direction back toward its original position. When the point of the pawl reaches the tooth on the ratchet wheel that it passed during the first part of its motion, up the tooth and rotates the shaft 28 one-v fourteenth of a revolution, teen teeth in the ratchet wheel. Before the point of the pawl has engaged the tooth on the ratchet wheel to turn the shaft 28 and thus operate the carriage, the dies have returned far enough toward their original positions so that the plate then in the carriage is enfed along for receiving the next impression.

It is sometimes desirable to move the carriage one space without embossing a letter. This is accomplished by moving the hand lever 26 one-half stroke, and for this purpose the guard 38 is provided with an indicator so that the operator may deter mine the amount of movement necessary t9 move the lever for giving a spacing movement to the carriage without operating the dies. In other words, moving the eccentric or cam shaft only about 45 and releasing it, the pawl will then engage the ratchet tooth before the embossing operation has proceeded to the point where the dies engage the plate, and on the release and return of said shaft the ratchet and consequently the carriage will be moved for one it picks v -7b with a gear wheel 27 almost there being fourmovement of the hand lever may take place in the reverse direction from that shown in the present arrangement.

It will be observed from Fig. 1 that a circular row of teeth is provided on the under side of the die carrier, and these are engaged by a detent roller a mounted in a cup or frame I) and pressed upwardly by a spring c to engage the teeth. This roller acts to accurately aline the die carrier.
