THOMAS A. NORRIS, OF BROOKTO, MASSACHUSETTS.

PUNCHlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 520,215, dated May 22, 1894. Application filed January 16,'1894. Serial No. 497,045. (No model.)

To ctZZ whom it may concern.-

Be it known that I, THOMAS A. NORRIS, of Brockton, in the county of Plymouth and State of Massachusetts, have invented a new and useful Improvement in Punching-Machines, which will, in connection with the accompanying drawings, be hereinafter fully described, and specifically defined in the appended claims.

In said drawings, Figure l is a top plan view of a machine embodying my invention; a portion being broken away to show certain of the parts. Fig. 2 is a side elevation of Fig. l; the lower part of the base being shown in section, and the right hand part of the shaft and the pulley being broken away. Fig. 3 is a vertical section taken as on line a, Fig. l; and Fig. 4 is also a vertical section taken as on line Fig. 1.

The object of my invention is to provide a machine in which the uppers of shoes can at one operation have all the holes punched for the insertion of eyelets in which the shoe lace is inserted; and the invention consists in a machine, provided with a base on which it stands, and from which rises a spindle on which is mounted a sleeve arranged tobe rotated and to be locked by a latch. Upon said sleeve are formed a series of platens, arranged around a common center, and in which are inserted, in suitably curved lines, a series of brass plugs against which a series of cutters act. Below said platens, and upon said sleeve are formed aseries of sleeves or tubes in which are inserted the stems of another series of platens to which are bolted a set of punch carrying plates, which punches perforate the shoe uppers by cnttingagainst said brass plugs as the disks are forced upward; andalower sleeve formed upon said base carriesl av plunger, that as it is reciprocated acts against an upper plunger to thereby reciprocate the punches that are carried by said upper plungers; said lower plunger being provided with a latch that holds the sleeve from rotation and is itself reciprocated by the acltion of the shaft which is revolved by a pulley and belt; all as will be next herein pointed out and then claimed.

Referring again to said drawings, A represents the base, which extends above line 5 as a stem, and is surmounted by nut B. In

said base is journaled the short shaft C, on which is secured the drivingpulley D.

Between line 5 and nut B is arranged sleeve E, so as to be rotated as desired 0n base A. A platform Fis formed on sleeve E near its top, and in said platform are a series of dovetail recesses a, in which are inserted the dovetail slides c as also gibs d; held by a screw 6. A series of platens Z2 are formed integral with dovetails c and in said platens are inserted a series of brass screw plugs e, arranged upon curves to conform to the curvature of the eyelet holes desired to be punched in the shoe. A piece 7 is formed upon or secured to platen b, and arranged next to part '7 is the stripper h, also secured to part b. A platen g having steady pins 8 that enter part b is held by bolts z' upon plate j; and a series of cutters fare screw threaded in said platen g. Said cutters are arranged upon the same curved -line as are studs e so as to cut against them. The plate; is formed upon or secured to stem la that is arranged to move in sleeve Z formed upon sleeve E. A latch 4 is pivoted in plunger y that reciprocates in sleeve z formed on base A; a spring being arranged, as shown, to engage the latch 4 in notch 9 in sleeves l. On the eccentric end of shaft C is a crank m which is connected with link n that is engaged at p with plunger y; a spring q serving, when not controlled, to throw said link out of alignment so that crank m will not raise the plunger; but by holding down arm t by means of cord w attached to a treadle the parts are rendered operative. A stud l0, threaded in plunger k serves as an adjustable medium by which contact between plungers y and It is effected. By thus arranging a series of platens b around a central standard, with means to bring either into operative position, and by varying the curvature of the line of studs e and cutters f so as to be in proper form for various sizes of shoes, this machine can in a moment be adapted to punch the eyelet holes for any size of shoe desired, by simply rotating sleeve E into the proper place to render the desired punches operative. Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In a machine for eyelet punching, a base formed with a central standard, a sleeve ar- IOO ranged to rotate on said standard, a series of platens arranged on said sleeve and provided with soft metal Studs e arranged in proper curved lines; a series of strippers h arranged 5 in proper relation to said studs; a series of hollow punches f secured in a carrying plate g and arranged to correspond to studs e; a series of platens j arranged on plungers 7c moving in sleeves Z and provided With means of contact with plunger y: the pulley shaft C, crank fm, link n, controlled by spring q and cord w, and a latch 4, by which the respective parts are interlocked, whereby the machine can be at once adjusted to shoes of varying 15 curves and sizes: substantially as specified. 2. The combination of shaft C, provided with pulley D, a crank m arranged upon an eccentric of said shaft, link n connected with crank m and plunger ly, the springq acting on link n, cord w secured to the outer end of link zo l f, the strippers h to clear the work from said x5 f punches and lthe platens b, all substantially as specified.
