EMBOSSING-PRESS.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed August 31,1906. Serial No. 332,822.

This invention relates to improvements in embossing presses, and the principal object is to provide novel, and exceedingly simple and inexpensive mechanism, which is entirely effective for the purpose, will permit the ready change of dies, and will accommodate itself to the varying thicknesses of the sheets, cards, or the like operated upon.

An embodiment of the invention, that is at present considered the preferable one, is illustrated in the accompanying drawings, wherein:

Figure 1 is a side elevation of the press. 7 Fig. 2 is a vertical longitudinal sectional view therethrough. Fig. 3 is a horizontal sectional view. Fig. 4 is a vertical cross sectional view. Fig. 5 is a top plan view of the carrier block. Fig. 6 is a horizontal sectional view therethrough, substantially on the line 66 of Fig. 4. Fig. 7 is a detail perspective view of the upper die plate and die members carried thereby Similar reference-numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated, a base 8 is employed, having centrally disposed angular inner and outer upstanding ribs 9, forming a recessed die-receiving seat 1.0. A cushion 11 of comparatively elastic material, such as felt, or the like, is placed between the ribs. The inner set of ribs is provided with upstanding holding pins 12. A yoke 13 extends longitudinally over the bed, and has its ends slidable on stud bolts 14 that pass through said ends. This yoke is normally held against movement, however, by nuts 15 threaded on the bolts on opposite sides of the yoke ends.

The yoke 13 is provided, between its ends, with depending guide rods 16, and a carrier block 17, located between the guide rods, has outstanding ears 18 slidably mounted thereon. An actuating screw 19 is threaded through the central portion of the yoke. The lower end of said screw has a suitable head 20 having a rounded lower face that bears upon the upper flat face of the carrier block, and the upper end has a cross arm 21. Coiled springs 22, located on opposite sides of the carrier block and yoke are secured thereto, as shown at 23, and serve to elevate the carrier block.

Suitable die plates 24 are arranged to rest upon'the bed, these die plates having openings 25 to receive the holding pins 12. The plates 24, as shown, are supported over the ribs 9 by the cushioning material 11, and are preferably provided on their opposite sides with dies 26, one of these dies thus being received in the seat 10, while the other is located beneath the carrier block. The said carrier block has a dovetailed guide-way 27 in its under side, adapted to slidably receive a die plate 28. Said die plate is provided with a suitable handle tab 29, and has in one edge a socket 30 to receive .the inner end of a spring holding latch 31, secured to one side of the carrier block 17 Dies 32 may be secured to the under side of the plate 28 by screws 33 or by any other suitable means.

In using the device, the article to be embossed is placed between the opposing dies. Afterwards the handle arm 21 is turned in the direction to force the carrier block and upper die downwardly against the tension of the springs 22. When released, the screw will automatically return to its original position. This appears to be due to the pitch of said screw, the single point of bearing between the head 20 and carrier block, and the give between the yoke and bed plate or base. In explanation of this, it may be stated that when the screw is driven down and the dies are en gaged with the article to be embossed, the yoke springs to some extent, and therefore when the driving power is released from the screw, the said yoke reacts, and the spring occasioned thereby assists in the elevation of said screw. The springs 22 only act to return the part 17 and hold screw up when at rest. It will be apparent that this structure is an exceedingly simple one, and yet is entirely effective. The parts are such that they may be inexpensively manufactured, and because of the peculiar construction of the bed, the lower die member may be made reversible, as shown. Further more by supporting said die member upon a yielding cushion, it will conform to the inequalities or varying thicknesses of the articles embossed so that better impressions are insured.

One of the most important features in connection with the use of an arched bar or yoke is the adjustable mounting of such bar upon the stud bolts. By adjusting the bar, the distance between the die and die plate can be varied, as desired so as to secure perfect cooperation between the parts when in action. Furthermore by adjusting the nuts at either or both ends, the die and die plate may at all times be made to properly cooperate even after the structure becomes sprung by the heavy pressure brought upon it.

From the foregoing, it is thought that the construction, operation, and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is:

1. In a press of the character described, the combination with a bed having a die member support, of a yoke extending over the bed and connected to the same on opposite sides of the die member support, an actuating screw threaded through the yoke and disposed over the support, the threads of the screw being of a pitch to permit the automatic return of said screw after its actuation, a carrier located beneath the yoke and engaged by the screw, and springs connecting corresponding sides of the yoke and carrier and located on opposite sides of the same for elevating said carrier.

2. In a press of the character described, the combination with a bed, of a supporting yoke extending over the bed, supports for the yoke, guiding means depending from the yoke between the supports, a die carrier slidably mounted on said guiding means, an actuating screw threaded through the yoke and bearing against the die carrier, and a spring connecting the carrier and yoke for elevating the former.

3. In a press of the character described, the combination with a bed having a die member support, of a yoke extending over the bed, depending guide rods connected to the yoke and located beneath the same, a die carrier block slidably mounted on said rods and arranged between the same, an actuating screw threaded through the yoke and bearing against the block, and coiled springs secured to the opposite sides of the yoke and block for elevating the latter.

4. In a press of the character described, the combination with a bed having a recessed die'receiving seat in its upper face, of a die member having dies on its opposite sides and arranged to be received in the seat upon the reversal of said member, an actuating member located over the seat and movable toward and from the same, a carrier operated by the actuating member, and a removable die mounted on the carrier.

5. In a press of the character described, the combination with a bed having spaced upstanding angularly disposed ribs forming a recessed die-receiving seat, of a yielding cushion located between the ribs, a reversible die member that rests upon the cushion and has dies on its opposite sides, an actuating member located over the seat and movable toward and from the same, a support for said actuating member, a carrier operated by the actuating member and yieldingly suspended from the support, and a removable die mounted on the carrier.

6. In a press of the character described, the combination with a bed, of a yoke extending over the same, connections between the ends of the bed and yoke, said bed having a recessed die-receiving seat in its upper side, a cushion surrounding the seat, depending guide rods connected to the yoke, a carrier slidably mounted on said guide rods and arranged over the seat, springs connecting the carrier and yoke, and an actuating screw threaded through the yoke and hearing against the carrier between the guide rods.

7. In a press of the character described, the combination with a base, of an arched bar or yoke, independent and adjustable connections between the ends of the bar or yoke and the base, a screw threaded through the arched bar or yoke between the ends thereof, and coacting dies, one of which is mounted on the base, the other being associated with the screw, said latter die being entirely free from the adjustable connections and being adjustable with the arched bar or yoke.

S, In a press of the character described, the combination with a base, of upstanding studs mounted thereon, a yoke having its ends slidably mounted on the studs, means for holding said ends in different positions on the studs, a depending guide carried by the yoke, a screw threaded through the yoke adjacent to the guide, and coacting dies, one of which is mounted on the base, the other being slidably mounted on the guide and associated with the screw, said latter die being adjustable with the yoke.

9. In a press of the character described, the combination with a support comprising a base and a yoke extending over the base, of a die carrier located between the yoke and base and having a flat upper face, springs having their upper ends secured to the yoke and their lower ends secured to the carrier, and a screw threaded through the support between the springs and having a rounded lower end that rests against the flat upper face of the carrier.

In testimony, that I claim the foregoing as my own, I have hereto aifixed my signature in the presence of two witnesses.
