IMPROVEID MACHINE FOR MAKING EYBLB'I'S.

The Schedule referred to in these Letters Patent and making pm of the lame.

To all whom it may concern Be it known that I, Tnonas Gunmen, ut' the city and county of Providence, and State of Rhode Island, have invented certain new and usefulImprovements in Eyelct-lllaking Machines; and I doihereby declare that the following is a full, clear, and exact description of the same, reference being bad to the accompanying drawings, making part of this specification, in which-- Figure l is a plan of my improved machine.

Figure 2 'is a detached view of the series of eyeletrnaking tools or instruments.

Figure 3 is a view ofone kind of heating and cooling-ap mratus, to be employed in said machine, for anhealing-purposes.

Figure 4 is a side elevation and section'ot' one of the sets of eyelet-making instruments, and the guide or clearer.

Figure 5 is a vertical section of said guide or clearer,

showing. the strip of stock therein.

Similar letters indicate corresponding parts in all the figures.

My invention consists- First, of a combination of a set of punches or instruments, that operate simultaneously.uponboth sides of a strip of metal, for performing some one of the operations of making eyelets therefrom, with a "compound guide and clearer, for guiding and holding the metal between said punches, for the perfin'mance of the operation, and for clearing the metal from the punches as the operation is completed. I 7

Second, in combining and arranging, in an organized machine for making eyelets, several sets of punches,

with their guides and clearcrs, as described, for performing successively the consecutive operations of raising, shaping, cutting out, and delivering eyelets in a complete and perfect form.

Thirdly, in -::ombining, in an organized machine for making eyelets from a strip of metal, by annmbcr of consecutive operations, a hcat ug-apparatus and a cooling-appzu'atus, for annealing the strip of metal at any suitable stage of the operation, so that the several operations mayfollow each other in rapid. succession, withoutintcrruptiou, and so that the eyelets may be finally delivered, perfectly annealed and ready for use.

To enable others skilled in thear to makeand use my invention 1 will proceed to describe the same.

In the said drawings, F is the ti'ame-uun'k of the machine, upon-which there is a number of stands, G G, &c., which atibrd hearings for the two dr1vmg shafts 1: E, and other stands, I I, which afford bear- These guides are stands, which are secured upon the face of the frame-work I], by set-screws i, or otherwise, so that; they may be set or adjusted in position.

The upper portion of the stands H is formed with a recess, that will hold and admit of a free passageof the strip of stock between the two punches, as shown in figs. 4; and 5.

On one side, ate, of the said recess or guide, a groove, is cutparallel with the recess, and sntiieiently wide to permit the raised portion of the stock to pass without; hindrance, as shown in fig. 5, and upon each side of the said recess, the eyelet-making punches or instruments, P and S, enter the stand H, and meet the strip of stock upon opposite sides thereof, and shape the same with great accuracy and precision,and then, after so doing, withdraw from contact with the stock, as it is held firmly, and thereby clears from the punches by the guides H, and the stock is permitted to pass along, so as to present a fresh surface to be operated upon-in like manner.

The ofiice of the guide and clearer is, to hold the stock-in position for the punches or eyelet-instruments to operate upon both sides of it simultaneously, and after such operation is completed, and when the punches are withdrawn, to hold the stock firmly in the same position, and by so doing, clearer free it from the punches.

The machiuerepresented in. the drawings has four sets of punches or instruments, but agreater or less number may be used, according to the nature of the operation, or the apportionment of the same among the number of punches, and the said punches are operated to effect the sliding movement by means of suitable cams or eccentrics, J, and connections I), from the two shafts E E, which are connected together, so that each shall move alike and at the same time, by means of the two connecting-rods K K, and cranks, at each end ofthe two shafts, or by means of an intcrmediate shaft and gears, or in any other suitable. manner, to efl'ect the purpose.

As represented in the said drawing, the first of the four sets of punches, P S, meets upon the stock, and raises a cup-shape thereon, as shown in fig. 2. g

The second set of punches, P S", elongates the said cup-shape.

The third set of punches, I S, forms the cup-shape into an eyelet-shape, and punches out the small closed end, and the fourth set of punches, P S, cuts the eyelet from the strip ofstock, and drops it, completed, into a receptacle.

The second, and perhaps the third of these opera tions, as described, may be dispensed with in making certain kinds of eyelets, as, for instance, the medium and larger sizes; or one or more intermediate drauing, or other operations, may be introduced in the making of the smaller or longer varieties.

in either event, however, in thus making eyelets by a number of consecutive operations, each tending to develop the eyelet-shape more and more, it is not only desirable, but necessary, to anneal or soften the stock before each operation is performed, to facilitatc the working of the same; and in order to dispense with the necessity of performing these several operations, above described, or those analogous thereto, in separate machines, and afterwards removingthe stock from each machine, and plunging it first in fire and then in water, to anneal the same, I have essayed to accomplish the same result in the machine above described, at suitable stages of the operation, by combining a heating-apparatus and a cooling-apparatus with the machinery which shapes the eyelet, and by so doing, being enabled to combine several conseeiltive operations in the same machine, andthis may he done in the manner shown in the drawings; that to say, between the first and second sets of punches, I arrange a gas-burner, a, of a suitable kind for heating qnic'kly;:.and beside this burner, I arrange a tank or receptacle, L, containing water, which may be delivered therefrom by an absorbent, (composed of wicking or other suitable material,) directly against thefiat surface of the stock, the burner 11 servingjas ,a heatlug-apparatus, and the water-tank L serving as a cool ing-apparatus, conjointly to heat and cool, and thereby anneal the strip of stock between the two operations.

I would also place a similar heating and cooling-apparatus between the second and third sets of punches, so that the stock maybe so completely annealed, just before the two final operations of cutting, as that the eyelet will require no,after-process of annealing, as is usually the practice.

Instead ot'a jet of gas for a heating-apparatus, and a tank of water for a cooling-apparatus, ablast-tiame from a gas blow-pipe, and a blast of cold air, each emanating from two pipes, arranged side'by side, and delivered against the surfzwe of the stock, may be used,

as shown in fig. 3; or any other suitable and convenient means of heating and cooling the stock, with sufll- ,cient rapidity to continue the several operations without interrupt-ion, may be employed.

It will belapparent, that by this mode of performing several consecutive operations upon astrip of stock,

it will be unequally contracted from its original length, as well as in the relative distance between any two sets of punches; and in order to compensate for this,

' and to provide for "the complete and perfect performance of each operation in its turn, considering this difficulty, I feed the strip of stock through the machine, to the several sets of punches successively, by means of a vibrating finger, b, operated near 1 he fourth or last set of punches, by means of the sliding bar as and cam g on shaft E, which finger catches into the last perforation formed by cutting out the finished eyelet, and thus moves the stock along, by a movement, the extent of which is graduated by the actual contraction of the metal between any two of the formations; and I further provide for overcoming this difli cult-y, bfrnaking the last, as well as the preceding punches, a eentring as well as a purrchirig-instrument;

There should also be an appreciable difl'erence of motion or lead in the position of the several cams or eccentrics upon the shafts E, so that no two sets of the tools would be operating, andv thereby confine the stock at two places at. the same-time, which, being skilfully carried out, will remove this difiiculty entirely.

. f Qlaims. What- I claim, and desire to secure by Letters Pat- .ent, is-- r LThe combination and arrangement of a set of eyelet-flaming instruments, which move and operate simultaneously upon both sides of a strip of metal, with a stationary slotted block to guide the metal, and prevent its removal by thewithdrawal of the instrunents, substantiallyas described.

2. The cornbination'and arrangement, in an organized machine, of a number of sets of eyelet-forming instruments, with their guides, as dESGllbetl, l-l such a manner-that the consecutive operations of raising,

shaping, cutting out, and delivering eyelets in a complete form, may be performed in rapid successiorn substantially as specified.

3. Combining, in an organized machine for making eyelets from a strip of metal, by a number of mechanical devices, operating consecutively, substantial] y as described, a heating-apparatus and a cooling-apparatus or device, for thepurpose of annealing the strip of .metal at any suitable stage of the operation, so that the successive operations, may be performed uninterruptedly, and for the purpose of delivering the eyelets from the machine completely annealed and ready for use.
