Application filed January 9, 1899. serial No. 791,690. (lilo model.)

To all whom it may concern:

Be it known that I, CHARLES S. ELLIS, a citizen of the United States, residing at Chicage, in the county of Cook and State of Illinois, have invented a certain new and useful'Die for Making Upholsterers Buttons, of which the following is a specification.

My invention relates to that class of dies which perform the oilice of forming and cutting an article out of a sheet of metal.

The principal object of my invention is to provide a simple, economical, and efficient die for the purpose'of making upholsterers buttons of met-a1 with the least expenditure of energy.

My invention consists principally in a male die composed of punches set in a metal plate and extending outwardly therefrom, one of the said punches being provided with a bendlug-finger for the purpose of bending the prong of the button into a position perpendicular to the head thereof, and a female die consisting of a metalplate having depressions and apertures corresponding in number, position, and shape to the punches of the male die.

The devices herein. shown are applicable generally to machines for the manufacture of articles by the use of dies, but are more par-' ticularly designed for use in the manufacture of upholsterers buttons, similar to those described in my application for Letters Patent filed August 15, 1898, the same bearing Serial No. 688,660. I

I shall not describe any mechanism for op erating my device, for I claim no invention of any machine for that purpose. My dies may be operated by hand or automatically through the use of steam or other power.

In the accompanying drawings, Figure 1 is a view in perspective of the male die, show 'ing the punches extending outwardly from the metal plate hereinbefore referred to and the bending-finger extending outwardly from punches.

'fed through the die, showingapertures made die, showing apertures made by'punches of modified form or design, Fig. 9 is a viewof a button. which may be made bya die having punches modified in form and'design, so as' to make the apertures in the stock shown in In the construction of .the die in accordance with my designs I provide a metal plate Xas a retaining-plate for the punches of the male die. In this plate I- fix two or more of the but in the; construction of my die the work done by the punches A and B, can be performed by a single punch having a shape corresponding with the depression 5. I do not care, therefore, in this application to be limited to a die-consisting of three punches.

My design shows three punches g" In Fig. 1, A represents apunch made of- 1 steel or other hardened metal designed for the purpose of cutting the aperture f in the metal strip, as-shown in Fig. 4. p

The second punch B'(show'n in Fig.1) is designed for the purpose of cutting the edges marked f in the said strip, as shown in Fig. 4.. This punch is designed to out out the prong of the button shown in Fig. 5, leaving designed for the purpose of stamping the head of the button.

0 represents the bending-finger hereinbefore referred to. The office of this bendingfinger will be hereinafter described. 7

Y is a hard-metal plate forming the upper portion of the female di e, across which'the stock or strip of metal from which the buttons are to be made may be fed through a feedingguide and underneath an overhanging stripper. (Not shown in my drawings.) This stripper may be simply a sheet of metal fastened to the said plate Y and extending over it just above the face of the plate, leaving space enough between the plate and the stripper to permit. of the uninterrupted pas sage between them of the stock. In this stripper or sheet and above the apertures (1-, I); and 0 may be cut spaces for the purpose of permitting of the passage of the punches A, B, and U therethrough to engage the stock beneath.

Y'represents the base ofthe female die, to which the plate Y may be attached by means of screws or bolts The letter a shows the aperture througl'i which the portion ofthe stock out out. by the punch A ma 3' fall. This aperture is provided with cutting edges l-o act in connection with the cutting'cdgcs of the punchA to cut out the stock in the manner "shown in Fig. 4.

The letter shows the depression corresponding with the punch B and provided with cutting edges throughout except along the line 12 inasmuch as the stock out by the punch l3 is not entirely disengaged from the strip, but is held along the line 12 it is necessary that a means he provided for disengaging the stock from the said depression I; after the conclusion of the process of cutting. I therefore provide for this purpose a lifting-post f, actuated by a helically-coiled springf", the office of this post being-t0 force the stock out of the depression I) when the punch 13 shall have been removed from con! tact therewith.

The letter a shows the aperture correspond ing at its upper end with the punch (land be ing of a-size sufficient at its lower end to permit of the passage therethrough of the stock out by the punch B. This apertureIprovide with cutting edges corresponding with .the edges of the punch.

The female die may be provided with a gage to check the strip at proper intervals as it is fed across the face of the die beneath the punches.

The mechanism operating the dies being set in motion, a strip of metal of proper width may be fed across the face of the female die, beginning at the point Z, and underneath the stripper.

As the stock passes beneath the punch A the actuating mechanism brings the punch into contact with the stock and punches out of it a portion thereof corresponding in shape with the aperture a. The portion of the stock out out will then drop through the aperture into. a receptacle designed to receive the same. The stock may then be advanced by the feeding mechanism into such position as will bring the portion. marked 1'' in i ig. -t into position corresponding to in Fight, so that the stock immediately surrounding may be properly engaged by the punch ii. The die again descending, the punch I3 will cut the stock along the edges marked f in Fig. 1L, leaving it still attached to the strip along. thev line I). In the meantime the punch A will have cut. out of the stock another portion corresponding in shape to the portion marked f lnfFlII. 4. On the withdrawal. of the punches the liftingpostf, actuatedby the spring f will lift the prong u out of the aperture b and disengage it therefrom, so as to'permit of its pas-- sagqbeyoud. The punches being withdrawn from contact with the stock and the pron-g,

being disengaged from the aperture 1), the actuating mechanism wzll again advance the strip until the portion cut by the punch B comes beneath the punch C. On descending the bending-finger C? will engagethe prong a shown in Fig. 5 and force it downward through the aperture 0 until it reaches a position perpendicular to the strip out of which it has been cut. The protuberance 0', coming into contact with the stock, will tend to depress it, as shown in Fig. 5, and the cutting edges of the punch U, engaging the stock,

will entirely free the button from the strip,'.

so that it may drop through the aperture c and intoa receptacle placed toreceive it; in

the meantime the pnnchesA andB will have strip atthe same instant of time. subsequentdescent of the male die a complete button will be turned out.

I am aware that a protuberance upon a punch similar to that shown by me and marked 0' has been used, and this I do not claim.

I performed their work on other portions of tho With each I While I have described my invention with more or' less minuteness as regards details of construction and as being embodied in certain precise forms, I do not desire to be limited thereto unduly or any more than is pointed too out in the claims. On thecoutrary, I 0011- template all proper changes in form, construction, and arrangement, the omission of immaterial elements, and the substitution of equivalents, as circumstances may suggest or necessity render expedient.

I desire to state specifically that I do not wish to be limited to a die for the manufacture of a button having a notched prong,

as shown in Fig. 5. A die constructed on thrprinciple hereinbefore described, one ofythe punches being provided with a bending-finger, will suffice for the manufacture of upholsterers buttons having prongs of any shape, and I contemplate the manufacture of all such buttons by the use of dies constructed as herein set out.

Having described my invention, what I claim isl. The combination of .a plurality of punches for cutting the'prong of an upholsterers pin or button, and another punch for cutting the head thereof, the latter being provided with a protubcrancefor indenting the head and with a bendin -fin er for bending 7 C! b a ting the head of the button, this prong beingproyided with a protuberance for indenting it, and with a bending-finger for bending the prong into a. position at 'a substantial right angle to the head, and a female die with apertures corresponding in number, size and position with the punches, all substantially as described.

3. The combination of a plurality of punches for cutting the propg of an upholsterers pin or button, a punc for cutting the head of the button, said punch being provided with a protuberance for indenting the head of the button and a bending-finger for bending theprong into a position at a substantial right angle to the head, and a femaletlie provided with a lifting-post actuated by a spring so arranged as to disengage from the die the cut stock, and containing apertures corre- ,sponding in number, size and position with the punches, all substantially as described.

4. In a die for making upholsterers but- 'tons,the com bination of a plurality of punches for cutting the prong and head of a button, and a bending-finger, all constructed for the Y purpose and substantially in the manner de scribed.
