Substituted for abandoned application Serial No.

441,643, May 4, 1942. This application November 10, 1943, Serial No. 509,751

' for receiving a short bolt [6 which passes through 1 Claim.

This is a substitute for abandoned application Serial No. 441,643, filed May 4, 1942, and relates to new and useful improvements in hot die stamping and embossing machines and has for its principal object the provision of an attachment adapted to be conveniently mounted on such a machine for holding roll foil in a convenient and labor-saving manner.

Another important object of the invention is to provide an attachment of the character stated which can be readily applied to stamping and embossing machines of conventional design.

Other objects and advantages of the invention will become apparent to the reader of the following description.

In the drawings:

Figure 1 represents a fragmentary perspective view of a press showing one form of the invention mounted to the head of the press.

Figure 2 is a top plan view of the form of inven tion shown in Figure 1.

Figure 3 is a side elevational view of the form of the invention shown in Figures 1 and 2.

Figure 4 is a rear elevational view of the device shown in Figures 1, 2 and 3.

Figure 5 is a fragmentary perspective view of a modified form of the invention showing the device attached to the bed of the machine.

Figure 6 is an elevationalview of the supporting frame for the form of the invention shown in Figure 5.

Figure 7 is a top plan view of the frame shown in Figure 6.

Figure 8 is a side elevational view of the hot die stamping block.

Figure 9 is a bottom plan 'view of the block.

Figure 10 is an end elevational view of the block.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 generally refers to a hot die stamping and embossing machine which includes a head 6 and a bed 1. The present invention contemplates a holder for strip foil or the like used in paper embossing.

One form of the invention is. shown in Figures 1, 2, 3 and 4 and as shown in Figure 2, includes an L-shaped bracket 8. This bracket 8 has a machine head attachable portion 9 and an inclined leg portion 10. The leg portion ID has a pair of plate extensions II, II riveted thereto as at l2. These plate extensions II are in close spaced relation and a pivotal plate l3 has one end portion disposed between these plates II and fulcrumed by a pin M. The plate I3 has an arcuate slot I5 both of the plates H and which is equipped with a wing nut l1, whereby the plate l3 which carries the roll of foil can be adjusted and held at any desired inclination.

-An elongated rod l8 has one end disposed through the upper end of the plate I3, there being provided a lock washer l9 on this end of the rod I8 at the inner side of the plate I3 and a wing nut 20 on this threaded end of the rod I8 at the outer side of the plate l3, whereby the rod I8 is held firmly in a horizontal position.

A half spool 2| is provided with internal threads for adjustability on the said threaded portion of the rod I8 and a lock washer 22 is employed for fixing the position of this half spool on the rod l8. Numeral 2 3 denotes a half spool having a smooth bore and between these half spools a roll of strip of foil 24 (see Figure 1) can be held. At the end of the rod l8 beyond the half spool 23 is a lock washer 25 and a wing nut 26, and a compression spring 21 is provided on the rod and interposed between -the lock washer 25 and the half spool 23.

In order to properly guide the foil strip directly under the hot die. stamp block, which is carried by the head 6 of the machine, a guide roller 28 is employed. The guide roller 28 is located on a pin 29 which projects from a block 30 through a slot 3| in a vertical guide 32. The block 30 rides in a guide groove of the guide 32. A' spring 33 is provided in the guide for exerting pressure against the block 30. The upper end of the guide is secured by a suitable means 34 to the inclined leg ID of the bracket; 8. The foil strip passes from the roll downwardly and under the guide roller v 20 to pass under the head of the machine.

A modification of the invention is shown in Figures 5, 6 and 7 and in this form of the invention the roll is mounted on the bed of the machine. Here, it can be seen that in order to accommodate the mounting, a frame 35 is employed, this frame consisting of a horizontal bar 35 and depending attaching legs 31, 31. This frame is attached to the bed I and to the bar 36 of the frame is attached an L-shaped bracket 38 having a declined leg 39 which is provided with an upstanding guide 32a and a roller 28a similar in construction to the guide 32 and roller 28.

A plate 40 is pivoted between a pair of spaced plates 4|, 42 projecting from the leg 39 and suitable adjusting means may be provided between the plates 4|, 42 and the plate 40 as in the instance of the plates 'II and [3 of Figure 3.

blocks 46, 41 between which asbestos plates 48,

49 are disposed. Between the asbestos plates is interposed an electrical heating element from which extends a cord 50 and this connects to an electric plug or may be provided with prongs to which an electrical connector may -be attached.

The bottom of the block 46 has a plurality of openings 5| to accommodate screws 52 of what-' ever stamping or embossing plate is to be attached'tothe unit.

f A'spindle or shank 52rises from the block 41 and this connects the stamping block to the head of the machine. Numeral 53 denotes a guide stud to prevent rotation of the block.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departin from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what'is claimed as new is:

In combination with a stamping and embossing machine including a head, and a bed, a strip roll holder comprising an L-shaped bracket fixed to said machine to provide an arm inclinin laterally therefrom, a pair of extension-forming plates on said arm fixed thereto side by side, a plate pivoted between said pair of plates for adjustment vertically thereon, means on said pivoted plate for supporting a roll of strip foil material to be fed therefrom between the head and bed of themachine, and a guideroller resiliently mounted on said arm and for guiding the strip between the roll andthe machine.
