IMPROVEMENTS IN MACHINES ron MAKING sinners.

TO ALL WHOM IT MAY OONCERN -Beit known that I, DAVID K. HoXsis, of the city and county of Providence, and State of Rhode'Island, have invented certain new and useful Improvements in Machines for Making Eyelet; and I do hereby declare that the following isa. full, clear, and exaeLdescription of the same, reference being had toV the accompanying drawings, making part of this specification, in which- Figure 1 is a plan of niy improved machin-e,

Figure 2 is a plan of a modified construction of a portion of the same, and

Figure 3 is a side elevation of the cutting-punch, and its attachment for "removing an adhering eyelet therefrom. v

Similar letters indicate corresponding parts in all the figures.

My said invention consists of a combination, in an eyelet.-making machine, of a punch, of the form ofthe interior of the eyelet, a die of the form of the exterior of the eyelet, and a tubular cutting-'punch at the rear of said die for cutting out the4 closed endof the eylet; also, of a modiiied construction of Vthe saidfeyeletforming punch, with a hollow cavity in the end, and an annular cutting-edge at the end, in combination with a soft-metal or other surface on the end of the Vrear punch for the said cutting-edgeto cut against, for the purpose of cutting out the closed end of the eyelet after it has been formed in the die by the forming-punchgalso, or with the cutting-punch which cuts ont the planchet fromwhich the eyelet is formed, a spring or snapper, for detaching the eyeletfrom the end of said punches if it should adhere thereto from any cause-all as hereinafter set forth.

In the drawiugs,'F is the-frame of the machine. S S are stands, in which are formed b v shaft B. T T' are stands, in which the cuttingI and forming-punches H and J slide, H being operated by the crank L on said shaft, through the medium of the connecting-rod f and the lever V,'and the punch Jbeing operated directly from the eccentric N on-the-shaft.

earings for the drivingi D is the stand in which the die e is held, which shapes` the exterior of the eyelet. In the stand M, the tubular cutting-punch G slides up to the rearof the die by,

means of the lever C, the connection I, and eccentric A, on the driving-shaft'. e

` The cutting-punch H eu'closes the eyelet-forming punch J and, rin connection with the sharp cutting-edge of the entrance of the die e, serves to cnt from sheet metal the disk or planchet from which the eyelets is' to be formed.4 The punch J, at the end, is shaped like the interior of the eyelet, and after the planchet has been cut by the punch H, the punch J carries it down int-o the die e, which is of the exact shape of the exterior of the eyelet, and the eyelet is thus formed between the punch and the die, in a manner well understood by those Who are acquainted with eyelct-making machines, all of the parts above described, and their operation, being com4 mon and well known. After the planchet has been carried down into the die, but just before the punch J has completed its movement, the tubular cutting-punch G .nicets the end of the eyelet Von the punch J, and is forced `against the eyclet, and, by the combined mov is cut out, after which the two punches are withdrawn from the die, with the completed eyelet clinging to the eyelet-shape ofthe end of punch J, from which it is stripped off by the withdrawal of said punch into the sur-V rounding punch H, and the eyelet falls beneath the punches, upon the frame, or into a. receptacle for the purpose Sometimes, the eyelet, after it has been stripped from the punch J, as described, will stick to the end of the punch ement of the two punchesG and J, the'closed `end of the eyelet Hoi\ 'ing to the oil with which the stick is lubricated, or from some other cause, and it becomes lnecessaryto detach t-hc eyeiet from the cnd ofthe punch, to avoid interfering with its subsequent operation. -This'I accom-- plish by means of the spring or snapper g, fig. 3,. attached by one end to the stand T, and having an incline at cz, which bears against the top of the lstud t, on the punch H, at the proper time, and the end of said spring being bent at right angles, so as to hit the eyelet on the end of the punch, as shown in dotted red lines; and being thus constructed and arranged, the movement of the punch H in the direction indicated by the arrow to the i position shown causes the stud t to pass the incline a, and permits the spring 'or snapper g to react, and its end to hit the cyelct smartly and detach it from the punch; and when, after this action, the punch again advances to perform its function, the stud tis carried against the incline a, and by that means the end of the spring is lifted out of thc way of the punch until its olices are required again, as before described.

In lieu of the cutting-punch G, constructed as above described, the eyelet-forming punch J may be formed with a cutting-edge on lthe end, by making. n conicalcavity in the end of' the punch,- as shown in iig. 2; and when thus constructed, the end of the rear punch G may be shod with a, surface of brass, l, as shown by red lines, so thatthe cutting-edge of the punch J may cut out the closed end of the eyclct by forcing the' hruss end of punch against said closed end, as it is thrust through the rear end of the' die', in the manner before expl-aued. v It will thus be seen that, u'nder my invention, it is immaterial whether the cutting-edge` is fox-'mcd upon the v punch G und the punch J made solid, or whether th'e punch J is provided with the cutting-edge und the end of the punch G shed or made solid, for the result produced in either case will be the same, z'. e., the' closed end o' :the eyciet in the forming-die will be out out by the combined movement of the two punches.

Having thus described my invention, I wish'it understood that I .de not claim either of the punches, H, J. or G, separately, nor do I' claim the die e in combination with the punches H 'ind J, as this has vbeen previouslyA known aud'used. A

`What I claimis- The combination of the eyeiet-forming punch J, 'the eycIet-.forming die c, and the punch G, arranged -andoperating substantially as herein described, for the purpose set forth.' v

I also claim', in combination with the eyelet-'forming punch J and cutting-punch H, as desciiled, the

spring or snapper g, arranged and operating substantially as described, for the purpose specified.
