PHOTOGRAPHIC EMBOSSlNG-PRESS.

SPECIFICATION formingpart of Letters Patent No. 514,603, dated February 18, 1894.

Application filed August 9,1893.

To aZZ whom it may concern.-

Be it known that I, DAVID D. McKee, a citizen of the United States, residing at Anderson, in the county of Madison, State of Indiana, have invented certain new and useful Improvements in Photographic Embossing Presses, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and marily for embossing photographs but applicable to other uses, and it has for its objects among others to provide a simple and cheap construction whereby great pressure can be obtained and the die held in its lowermost position for any length of time desired. I ernploy a novel form of toggle connection between the die-carrier, the operating lever and the uprights of the press. I provide for the of movement and results. I improve in the details of construction in general.

Other objects and advantages of the invention will hereinafter appear -and the novel features thereof will be specifically defined by the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification and in which Figure 1 is a perspective view of my improved press. Fig. 2 is a substantially central verticallongitudinal section through the same.

Like letters of reference indicate like part in both of the views.

Referring now to the-details of the drawings by letter, A designates the base of the machine which may be provided with the perother means by which it may be secured to the table or other support. Rising from the A which serve as guides for the die-carrier, and at their upper ends these uprights converge as shown in Fig. 1 and are connected by the plate or yoke A which may be adj ustably held thereon and which is provided centrally with an opening for the reception of a screw rod which will soon be described. Rising from the base are the guide pins a which Serial No. 482,741. (No modehl serve as stops and guides for the photographs or cards as they are placed in the press.

B is the anvil detachably fitted on the upper face of the base, having a rabbet b to receive a corresponding rib a on the base as seen in Fig. 2. The upper face of the anvil is raised as seen at b to accomplish the embossing.

C is the die-carrier; it is provided with apertured lugs c as seen in Fig. 1 which loosely embrace and are sleeved upon the uprights A and the carrier is thus guided in its vertical movements. D is the die which matches the anvil and which is detachably mounted on the carrier as by havinglugs d which pass through slots in the ends of the carrier as shown and are held against displacement by removable pins 62' as shown.

The die-carrier is made heavy near its center as the pressure is made downward thereon, and at its center upon its upper face it s provided with the ears 8 between which 13 pivot-ally held on a removable pin e the arm or lever E the other end of which is bifurcatcd as shown at e and between the bifurcations is pivotally held on aremovable pin f the operating lever F which has a suitable handle portion F; the other arm f Of illllS lever is pivotally held between the bifurcated end 9 of the swivel bolt G by a removable pin 9. This bolt G is screw threaded as shown best in Fig. 2 and passing through the hole in the yoke or plate A receives upon each side thereof a nut H as shown by which the same is held in place and by which it may be adjusted up or down as may be desired. The lever F- is formed upon its under side near'its pivot f with a notch or shoulder f as shown in both of the views which serves as a stop when the lever F is brought into its horizontal position as seen in Fig. 2. The levers E and F and their connections form an efficient toggle lever by which great pressure can be obtained, and when the parts are brought into the position in which they are shown in Fig. 2 they are locked and may be allowed to remain in such position as long as desired without extraneous holding means.

Modifications in detail may be resortedto without departing from the spirit of the invention or sacrificing any of its advantages.

I-Ieretofore in the art of mounting photo- ICO graphic prints the backing or card mount has been embossed with a recess and the print has been trimmed to fit said recess and inserted therein. This practice has been necessitated, from the fact that the print being on light, thin, paper and mounted in a damp condition rendered it exceedingly liable to become torn, marred or otherwise damaged, if an attempt to emboss the same and the backing simultaneously, be made. In embossing presses designed to accomplish this work as heretofore constructed there has been employed soft rubber arranged to contact with the print being mounted and embossed to prevent, if possible, injury to the print. fact metal or other similar hard anvils and dies have been discardedbecause of their other and the direct movement of the die at the instant the embossing is accomplished I am enabled toperform the operation without the slightest iuj ury to the most delicate print. My anvil B is transversely convexed throughout its outer margin which margin merges into a convex raised portion adjacent all around to said margin. My die is concave to fit said convex margin all around and tojust embrace the outer edge of the convex raised portion of the anvil. Otherwise the die is open above the anvil.

In embossinga card mount and print mounted thereon simultaneously the same is placed face downward and as the die approaches the anvil the mount is gently curved from its flat condition to agree with the convexity of the anvil. In this curving all of the tension or tearing strain istransposed to the card mount or backing and a surplusage of material is provided in the tender print, the concave side, by means of the entire absence of strain thereon, at the instant that the final embossing pressure is applied. This occurs when the last downward movement of the die is produced by bringing the lever to the position shown in Fig. 2. Any excess of downward movement is prevented by the stop F on the lever F, the adjustment for mounts of varied thicknesses being accomplished by the nuts H H, as hereinbefore described.

It will be observed that the opening in the die prevents any pressure whatever upon the illustrative field of the print, t'. e., the picture itself and this advantage may also besecured by the opening in the anvil so that it will not come into contact with the picture itself on the print side of the mount; 7

What I claim as new is 1. The combination of the anvil having a transverse convex outer margin surrounding a transverse convex raised portion adjacent all around I to said margin with the transversely concave die agreeing with said margin of the anvil and embracing the convex raised portion thereof and otherwise open over said anvil, substantially as specified.

2. An anvil having a transverse convex margin and adjacent raised convex portion combined with a concave die, fitting said margin and embracing said raised portion, a base, a platen for carrying the die and toggleJever mechanism one of said lovers being provided with a stop to limit the downward movement of the platen, substantially as Specified.

3. The combination of a convex anvil having a margin and an adjacent raised portion and a concave die agreeing with said margin and embracing said raised portion the same being open to prevent pressure on the central portion of a photograph or other article embossed therewith, substantially as specified.

4. The combination with the base with its uprights and yoke, of the die-carrier guided by said uprights, the lever pivoted to the carrier, and having bifurcated upper end, the operating lever pivoted in said bifurcated end and having a notch, the adjustable bolt in the yoke, and the part on the bolt pivotally connected with the operating lever, as set forth. I

In testimony whereof I affix my signature in presence of two witnesses.
