Specification of Letters Patent.

Patented Aug. 8, 1916.

Application filed November 17, 1911. Serial No. 660,772.

T 0 all whom it may concern:

Be it known that I, ALEXANDER F. Pinn- IPPI, a citizen of the United States of America, residing in the city ofSt. Louis and State of Missouri, have invented certain new and useful Improvements in Embossing- Presses, of which the following is a specification.

This invention relates to embossing presses, and has for its primary object to provide an improved construction, combination and arrangement of parts in a device of this character whereby such a machine can be simply and economically constructed to have the mechanism efiicient and to 00- cupy a limited floor space.

One of the objects of the present invention is to provide improved means whereby separate and distinct movements can be imparted to the die and counterdie, respectively, for the purpose of enabling these embossing parts to be cooperatively disposed by the initial movement of large scope, and the actual embossing action to be confined to a small movement of great power and efiiciency.

A further object is to provide improved means for automatically filling in the space between the counterdie and the rigid portion of the framework of the machine for the purpose of securing'a rigid support for said counterdie during the embossing act-ion.

Another object is to provide an improved die controlling mechanism comprising a novel and useful toggle movement and an improved device for reciprocating said die into and out of operative position under a resilient pressure, said reciprocating device being further constructed and arranged to effect an unyielding pressure during the movement of the die under the wiper, as will be more fully hereinafter described.

Other and further objects will appear in the specification and be specifically pointed out in the appended claims, reference being bad to the accompanying drawings exempli fying the invention, and in which,

Figure l is a side elevation on the power side of a machine constructed in accordance with the principles of this invention. Fig. 2 is a side elevation of the opposite side of said machine. Fig. 3 is a front elevation of the same. Fig. 4 is a rear elevation of the same. Fig. 5 is a section on the line V-V, Fig. 4. Fig. 6 is a similar section, showing the parts in embossing position.

Fig. 7 is a fragmentary front elevation of the upper portion of the machine, showing the counterdie mounted in embossing position. Fig. 8 is adetail fragmentary section on the line VIIIVIII, Fig. 7.

Referring more particularly to the drawlugs and to the embodiment shown therein, the bed frame 1 of the machine serves to mount a pair of side frames 2 and 3. The upper longitudinal rails 4 and 5 of the side frames serve to reciprocably mount a carriage 6 for a printing embossing die 7, said die being adjustably mounted on the carriage m a mannernot specifically concerned in the present invention; To adapt the carriage 6 to travel easily into and out of embossing position, as will be hereinafter more fully described, a pair of rollers-8 is provided which travel on rails 9 to and from embossing position, shown in Fig. 6.

Projecting upwardly from the relatively heavy transverse portion 10 of the bed frame are a pair of rods or standards 11 crossing the upper ends of which is mounted a heavy cross-head 12. Said standards 11 are rigidly connected with the side frames 2 and 3 by means of the forward cross rail 13 whose extremities conform to the standards 11, being secured thereto by caps 14.

Referring more particularly to Figs. 5 and 6, an elevator or pusher block 15 is mounted to reciprocate vertically between the front plate 16 and cross rail 17 which are rigid with the side frames 2 and 3. The upper portion of the pusher block or elevator is provided with a recess 18 for the reception of the die supporting carriage when it is moved into position for the embossing operation. For the purpose of constraining the carriage 6 to its proper path of movement, I provide along the top edges of the side frames 2 and 3 a pair of guide rails 9, under which project flanged plates 20 which are rigidly secured to the carriage 6 for this purpose. Said guide rails 9 are terminated short of the path of movement of the elevator or pusher block 15, so that at the eX- tremity of the movement of said carriage 6 the plate flanges 20 will be free to be displaced vertically during the embossing action to be hereinafter described.

Referring now to Figs. 1, 3 and 4:, power may be delivered to the machine from any suitable source by means of a belt (not shown on the drawings) which may pass about the driven pulley 21 which is keyed to the pulley shaft 22, upon which is also keyed a fly wheel 23. A pinion 24, which is keyed to the shaft 22, meshes with a spur gear 25, which is keyed to the main drive shaft 26 of the machine, which is journaled in side frames 2 and 3. Swingingly suspended from a fixed power or axle-shaft 27, is a manifold connecting yoke comprising a tubular body 28, a central bearing piece 29, and lateral bearing pieces 30, which bearing pieces serve to swingingly mount the yoke on the shaft 27. In order to impart swinging movement to the yoke 28, I preferably provide, at one end thereof, a crank arm 31 which is connected by rod 32 with a pin 33 on the spur gear 25. For the purpose of adjusting the effective movement imparted by the crank pin 33, I provide the crank arm 31 with a slot 34 within which a pin 35 carried by the end of rod 32 may be adjusted. Depending from the connecting yoke 28, at substantially the center thereof, is a power arm 36 which, as shown in Fig. 6, is provided with a tubular socket 37, within which reciprocates the hollow bolt or pin 38. A compression spring 39 imparts a tendency to expel the pin 38 outwardly for a purpose to be made clear. The outer end of the bolt 38 is provided with a boss 40 through which passes a connecting pin 41 which is secured within the upper branches 42 of an H-shaped connecting link 43, the lower branches 44 of said link being pivotally connected by a pin 45 with a throw lever 46 which is pivotally mounted at one end on a pin 47 in the bed plate of the machine. The upper end of the throw lever 46 is pivotally connected by a pin 48 with a connecting link 49 which serves to transmit power to the die carriage 6. As the carriage 6 travels forwardly, it passes 'beneath and into contact with an inking roller 50, and immediately thereafter, under a wiper web 51 which is caused to travel around a suitable form 52 by mechanism not shown on the drawings, but which is driven by the connecting rod 53 (see Fig. 1), whose lower end is provided with a pin 54 adjustably mounted in the slot 55 of the rocker arm 56, which is integrally connected with the manifold yoke 28. The ink roller 50 is supplied with ink from a fountain roll 57 which operates in a fountain 58, said fountain being mounted upon a carriage 59 which is reciprocated by a rocker arm 60, which is free to swing upon the cross shaft 27 under the action of a-connecting rod 61 which is slidable through an eye bolt 62 pivotally mounted in the upper end of the slotted link 63. The said link 63 is swingingly mounted upon a bracket arm 64 form ing a rigid portion of the side frame 2, and is adapted to be oscillated to and fro by means of the pin 65 which slides in the slot 66 extending along the link 63. In order that the fountain roll 57 may have a resilient pressure imparted to it against the ink ing roller 50, a spring 67 is interposed between the end of the rod 61 and the eye bolt 62. Links 68 connect the arm 60 with the fountain carriage 59.

As will be seen in Fig. 1, a pinion 69 which drives a sprocket 70 transmits power through a chain 71 to a sprocket 72, which drives the fountain roll 57. The bell cranklever 73, which is connected by the tension spring 74 to the side frame 3, has a roller 75 at the end of its other arm for maintaining the chain 71.

Referring now to Figs. 2, 3, 4, 5, 7 and 8, the cross head 12 has embedded therein a pair of spaced'guide pins 76 which project downwardly from the lower face of said cross head. Secured to the end face of said cross-head is a pressure block 77. And slidably mounted upon the pins 76, is an anvil block 78, upon which is mounted the counterdie 79 by means of an integrally formed dovetail slide. On either end of the anvil block 78, is mounted a cam roller 81 with which engages a cam 82 which serves to support the anvil block and counterdie during the greater portion of its up and down movement, to be presently referred to. The downward movement of the anvil block 78 is limited by stops 83 which are rigidly supported from the cross head 12 by means of brackets 84.

By an inspection of Fig. 2, it will be noted that the cams 82 are provided on the ends with pin levers 82 which are pivotally sup ported at 82", and are provided at their rear ends with pins 85 which travel in the crooked slot 86 formed in the lever arm 87, which is rigid on a pintle 88, which is journaled in suitable brackets carried by the cross-head 12. Dependent from the pintle 88 are a pair of links 89, which are pivotally connected with other links 90, which serve to laterally displace the filler block which will now be described: Said filler block, as shown in Figs. 4, 5, 7 and 8, comprises, in the present embodiment, a plural ity of vertically disposed plates 91, which are integrally united above by a transverse plate 92 and intermediately by the transverse plate 93, said filler block being slidably mounted on the transverse bearing plate 94, the purpose of this block being to form a chock between the counter-die anvil and the cross head 12 during the imparting of embossing movement after said counterdie has been moved into its lowermost position. In order to provide means for retaining the filler block in proper cotiperative connection with the anvil block 78, I preferably provide a pair of guides 95 which, as shown in Fig. 4, slidably engage in grooves formed in the outside vertical plates 91 of the filler block; and while permitting said filler block to slide laterally with respect to the anvil block 78, hold said elements against relative vertical movement.

Referring now to Fig. 2, power is transmitted to the operating cam 82 by means of a connecting rod 96 which has its lower end pivoted at 97 to the lever arm 98, which is pivoted at 99 on the side frame 2. The rear end of this lever is provided with a crooked slot 100 for a purpose to be hereinafter set forth, within which travels a roller 101 carried by a pin 102 projecting from the extremity of the rocker arm 103, which is integrally formed with a manifold yoke 28. For imparting the necessary vertical movement to the elevator or pusher block 15, the present invention contemplates the provision of a toggle movement in which the levers are of relatively great length and arranged so as to have but a small lateral displacement for effecting the embossing movement. In this manner, great power may be secured which, by reason of the initial movement of large scope imparted to the counterdie, enables the employment of a short travel movement and a cam movement of correspondingly small scope of action. Toward the attainment of this purpose, I preferably employ an upper link 104 which is pivotally connected at its upper end to the pin 105 mounted in the pusher block 15, and a lower power link 106 which is pivoted at 107 to the bed frame. In the rearwardly projecting arm of the power link 106, is journaled a cam roller 108 which is adapted to be engaged periodically by a cam 109, which is connected to the main power shaft 26.

In order to provide a quick-action, breakaway movement for returning the toggle levers to the position shown in Figs. 2 and 5, I preferably employ a cam lever 110 which is pivoted at 111 in the bed frame and carries a cam roller 112, which is actuated by a projection 113 of the main power shaft 26. The upper end of the cam lever 110 is connected by a slotted link 114, the slot 115 in the forward end of which receives a roller 116 which forms a pivotal joint between the toggle levers 104106. The tension spring 117 serves to hold the slotted end of the link 114 against the roller 116 with a resilent pressure as soon as the parts are in the position shown in Fig. 2.

lVhen the parts are thrown into the position shown in Fig. 6, to produce the embossing action, the roller 116 is moved to the forward end of the slot 115, and at the completion of the embossing movement, the action of the cam finger 113 upon the roller 112 serves to flex the joints between the toggle levers, and immediately the parts are returned to the position shown in Fig. 2 under the action of the tension spring 118. Rigidly supported from the side frame 3, is an arcuate cam 119, along which travels a cam roller 120 carried by the extremity of the pintle 41, the purpose of this cam being to retain the plunger 38 in its innermost posi tion during the travel of the die carriage 6 beneath the wiper 51. It will be seen, therefore, that at this stage of the movement of said carriage, there will be a positive movement without resiliency for driving the carriage forward. The cam 119 is concentric with the shaft 27, so that there is no variation in the relative positions of the plunger 38 and its socket until the cam roller 120 reaches the forward extremity of the cam 119, when, as shown in Fig. 6, the spring 39 becomes active and maintains a continuous resilient pressure through the link 43 upon the lever 46 to prevent the return movement of the carriage before the embossing movement has been completed. In the extreme forward position of the carriage 6, it is locked against a return movement until the manifold yoke 28 swings backward.

The operation of my improved machine will now be understood, and briefly stated is as follows: In the initial positions of the several parts, it will be seen, from Fig. 3, that the wide space is provided between the die and counterdie. As the die carriage 6 is caused to travel forwardly by the forward. movement of the manifold yoke 28, the cam roller 101, traveling in the slot 100, works as an idler in the lower end of said slot; but as it travels upwardly through the slot 100, it positively engages the upper surface of said slot, imparting a downward movement to the connecting rod 96 and cam lever 82, the result being that the counterdie 79 is caused to descend to within a very short distance of the plane assumed by the die 7 at the upper end of its embossing movement. Simultaneously with this downward movement of the die 79, the filler block comprising the pressure blocks 92, 93 and 94, is lowered, the cam pin 85 during this portion of the movement traveling through the lower portion of the slot 86 in the lever 87. Near the end of this downward movement of the die, however, said pin 85 throws the lever 87 forward to introduce the filler block into chocking position, shown in Figs. 4 and 8, so that during the embossing movement 115 which follows, the counterdie is rigidly supported from the cross head 12. The upper end of the slot 100 is designed to permit a period of idle travel of the roller 101 so that the vertical position of the counterdie will 120 remain unchanged during the embossing action. The counterdie being thus in rigidly mounted position, the cam 109 on the shaft 26, has by this time traveled around into engagement with the cam roller 108; and by 125 means of the toggle action already described, elevates the carriage 6 which is free at this stage of the mox'ement to move vertically, and completes the embossing movement. Immediately after the cam 109 moves away 130 from the roller 108, the projection 113 engages the cam roller 112 and by flexing the toggle joint through the agency of the lever 110 and slotted lever 114, permits the parts to return to initial position in readiness for another operation of the machine.

It will be understood that while I have described a specific construction of the machine herein shown, as embodying my invention, I wish to secure protection broadly for certain fundamental kinematic movements exemplified in this machine.
