Be it known that I, .JOHN-MATHIS, of Ottawa, in'the county of La Salle, in thc State of Illinois, have invented a new and improved Machine forlunching LeatheifStraps for Fly-Nets; and I do hereby declare that the following is a'full and-exact description thereorefcrence being had to the accompanying drawings, and to The naturek of my invention 'consists in constructingafmachinc for punching series of holes in leather straps, the operation being done by means of turning a crank the machine also doing its own feeding, and is 4The machiueis also provided with a simple and eilicienti deviceY for regulating the distance between the holes,

' To ena-ble others skilled inthe artsto vmake andi-useiny invention, I will proceed to describe'its construc'- e tion and operation.

' Figure-1in the drawings is a verticalfpln.

Figure 2 is also a vertical plan. V-ligure 31's a vertical 'section through al), iig. 1. v

The lineslin redexhihit the motions-and the extent ofthe motions of the movable parts.

y Iconstr'ucta frame, A, oi` cast iron,.in two parts, the parte` being 'connected-at the bottom by means of f the connecting-bars, B B. A shaft, O, having bearings nfbothparts'of' the frame, A, passes `through said frame, having on it a'pulley, D, of cast iron, `which .pulley is coveredl by a hoop' or rimV of sheet brass, E.

Through the-top of the frame A" passes the crank-shaft E, hayingcn' one.sideabalance-wheel, Gr,on the other end a crank, H, and in the centre the shaftA itself isbnt 'to form the crank I.' To the cranlzIis attached the pitlnan J. This Pitman is made 'oftn'o'headgJ and'Jthe one having-a;right-handnd the other a Leitha-ndl thread. i These screw into alo'ngnut or sleevc,lK,.in `such aman'ner'that, by turning the nut or sleeve K` the pitmanJ'can hema-dc longer or-shorter. Tothe head J2 is attached vthe rod L, which hasat its lower end a flange, into which arc fastened .the hollowvpunches M M. Y `It will be seen that, vby turningthe crankshaft F,'1

4the will. will receive ythrough the pitmanJ a reciprocating motion, itsdownward motion being exactly to't-he point where the hollow punches M M touch the brass'rim E. The rass rim E has attached,.at one point Aof its circumference, a steel hook,1N,^in'to whi'chis hoolted therstrap to be punched. v i

At the Vouter 'endof theshaftC is keycd'a ratchet-wheel, 0,'which is driven by a pawl, P, through' the lever Q, thc rod'R, and the crank H, in such amanner that, forevery turnofv the crank-shaft F,"the' vratchetwheel O,V and consequently the pulley D, areclriven-a certainY distance, to be regulated bythe disposition-of a.l

'series of' holes, g/gfgg/in the lever Q, in sucha manner that thepawl P will take hold of a greater Vor less nunc--4 hervoil the teethoffthc ratchet-wheel Oi.4 In order-t prevent the wheel O from turning backwards,'asecondf awl, S, is ada ted, in connection with an ecce'ntric,'T, b sineans of which the awllS can be set in `ust the P P y P J proper position toretiin lthe wheel O in thc identicall `placeto which it has been, carried byvea'ch successive 'movement of thepawll). u Y y I The cross-bar U serves as a' g|.1idt a to the rod L, vand has. also' attached to` the elastic guide V, which presses down oni the strap*Y to he punched.'` To ,accommodate itself to.dii`erent widths-of straps, the guide V has a'bolt, W, through it, by means of which the guide V can bei made wide or narrow, it beingmade elastic cnoughto give or compress as Vmuch as is'rcquired. To operate the machine, it is necessary to first punch a hole by hand in the' strap, after lwhich itis hooked to the hoch N, and, after bringing it under the punches M M,

it Vis only necessary to turn thcbalancc-wheel Gyewhcn, for each o`f its revolutions, a pa'irof holes willbe punched,

`When it is desired to' change `the gaugebr distance between the punches MM, the rod L is removedhy disconnecting it from -thepiman J, and anotherlofa'diiierent gauge is inserted` in its placef What I claim as In-y invention, anddesirctos'eeure'by Letters Patent, isA

1.4 The' pulley D, the brassnrimfF, the hollow-punches M M, the rod L, the pitinanJ, and the crank I, when combined with each obher in a. machine for punching straps for diy-nets,

for the purpose described n the foregoing speeieetion-. i

2. The ratchet-Wireel O, the pnwl i?, the iever Q, the rod B', the crank H, the pa'wlS, and the eceenizre,l T,

when combined withencb other in a, 'mech-ine for punchingieather straps for {ij-nets, substantially as and for the purpose described inthe-foregoing speeieation. y v y i '3. The eastic guide V, when applied to a machine for punching leather straps for {1y-nets, substentiallyes and for the pnrpos'e described.
