MACHINE Fon MAKING BUTTONS.

SPECIFICATION forming part of Letters Patent No. 372,011, dated October 25, 188'7.

Application filed July 7, 1887. Serial No. 243,640. (No modell To ctZZ whom it may concern.-

Be it known that I, LINCOLN E. OHAoE, of Freetown, in the county of Bristol and State of Massachusetts, have invented new and useful Improvements in Machines for Making Buttons, of which the following is a specification,reference being had to the accompanying drawings, in which- Figure l is a front elevation of a portion of ro a machine embodying my improvements sectioned on line l l of Fig. 3. Fig. 2 is an enlarged section on line 2 2 of Fig. 3. Fig. Sis a plan, partly in section, on line 3 3 of Fig. 1. Fig. 4 is a section enlarged on line 4 et of Fig.

i5 3. Fig. 5 is a like section with the feed-slide in a different position. Fig. 5a is a side view, partly in section, on line 5a of Fig. 5.

My invention relates to machines of the class described in my Letters Patent No. 2o 359,997, dated March 29, 1887; and it consists, mainly, in a new construction of the formingdic, by which it not only serves its own function as a forming-die, but also forms a shank and presents it properly to the button-blank.

The other features of my invention relateto mechanism for feeding and severing the Wire and indenting it to form an anchor fastening.

The machine shown in the drawings is in 3o all respects substantially like my patented machine, except so far as concerns the construction and operation of the die and the mechanism for feeding the wire to form the eyes or shanks of the buttons, and I have not lettered those parts, which are the same as those shown in my patent above referred to.

Th'e die is formed in two parts, a c', as shown in Figs. 2, 4, 6, and 7. The part a is fast to a die-holder, a2, which is rigidly attached to the 4o frame-work of the machine. The other part, a, is fast to the reciprocating die-heldere,

which is reciprocated by thelever l and slotted link 2, the link 2 being connected by a stud through the slot in link 2 with a slide, which is slide L of my patent above mentioned.

ciprocating die a. This die ct is'then forced to place to make a complete die of c c', and that bends the piece of wire into the form of the shank or eye of the button, with its legs project-ing up from the bottom of thedie, to receive the button-blank when it is punched out and forced by the punch into the die in the wellknown manner.

It Will be seen that the projection from the parta enters a recess in the part a, as shown in Figs. 6 and 7, this projection and recess making ashank-forming or eye-forming mechanism; and it is this split die with this recess and projection which is the main feature of my invention, and which makes a more positive, simple, and compact contrivance for forming the shank or eye and holding it in proper relation with the die than any other known to me.

The feed mechanism shown is also a feature of my invention; and it consists in a clamp,

b b', mounted upon a slide, B, which slide is reciprocated by the lever B. This lever passes through one end of the clampinglcver b, so that during the first part of the motion of the lever B the clamping-lever b clamps the wire between thc other end of the clamping-lever b and the clamping-jaw b upon the slide B. This not only clamps the wireiirinly, but also enables me to indent the wire by -ineans of 8O small projections on the clamping-face of the lever b, as shown in Figs. 4 and 5, and these indentations serve to make the prongs diverge,

as shown in Fig. 7, giving the shank a firm and secure hold upon the body of the button.

The slide is moved forward by the motion of the lever B'until it is stopped by contact with the die-holder 2,(01 some other suitable stop,) when the further motion of the leverB moves the lever b slightly and causes it to force the go wire against the cutter O, V(see Fig. 4,) Which is firmly fastened to the frame of the machine, the projections on the rubbing-face of lever b at the same time being forced into the Wire to indent it, as shown in Fig. 4. The backstroke of the lever B opens lever I), so that it and slideB are carried back to the position shown in Fig. 5 without moving the Wire. The lever B is actuated by wiper B2, which is fast to the reciprocating part of the machine, as will be rco c1ear',wibh0nb furtherdescription, to allsklied the clamping-lever b, clamping-jaw b', and

in the art. slide B, combined and operating substantially What I claim as my invention is as described. 1. The split; die a a', having the shank-form- LINCOLN E. OHACE. 5 ing projection and recess, substantially as and Witnesses:

2. The Wire-feed mechanism consisting of F. E. FULLER.
