PUNCHINGrMACHINE.

To aZZ whom it may concern:

Be it known that I, ALVAH F. SPooNER, a

citizen of the United States, residing at Sterling,in the county of Whiteside and State of Illinois, have invented certain new and useful Improvements in Punching-Machines and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to 'make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to that class of machines used for punching holes in metal,wood, leather, or other material; and it consists, essentially, first, in a novel means of actuating the punch second, in a novel method-of actuating the feed by means of the punch; third, in an improved method of seating the punch; and, fourth, ina provision for indicating the number of holespunched.

In the drawings, Figure l is a side elevation of a machine embodying my invention. Fig. 2 is an end elevation. Fig. 3 isa detail view. Fig. 4 is a perspective view of the guideway to lead the material to be punched under the punch.

A A are plates forming the sides of the machine, fastened together in any suitable manner, and furnishing the bearings for the crankshaft D andrests for the punch bedplate.

B is a punch-standard pivoted tothe bedplate 0 through the ears a, and having at tached to .its front side the punch-holder b, which latter is attached to such standard B by a set-screw, e, passing horizontally through a vertical slot in the punchrstandard B into a threaded hole in the punch-holder b. In the I horizontal projection sof the top of the punchstandard 13, over the upper end of the punch holder 1), is seated a vertical set-screw, f, the lower end of which abutting against theupper end of the punch-holder b assists in holding I the latter against the resistance ofthema- I terial punched, andis used to] adjust the punch vertically. In the punchholder bis formed the round vertical hole It, into which the shank-holder of the punch or punches his SPECIFICATION forming part of Letters Patent No. 289,577, dated December 4, 1883.

fitted, said holder being held in place by the horizontal set-screw g, which passes through the front wall ofthe hole t and abuts against the punch-shank holder. IWhere two or more punches are used, by placing their shanks in the prop er position and securing them in place, as above described, the holes I made by ,the punches may be punched longitudinally in the material punched, or diagonally, transversely, or in any intermediate'position therein. The punch-standard B, at a point immediately below the 'setscrew e in its upper projection, is dividedinto two arms, w, which pass backward on each side of the .bed-plate O, and from its point of attachment to saidplate G at c, on the side nearest the operator, there eX- I tends downward and forward the arm '0.

At 9 is shown a feed-clamp pivoted to the side plate of the machine, between which clamp and the punch bed-plate O the material to be punched is held in position while its forward part .is under the punch h. The clamp is made to act with sufficient power for this purpose bythe wire springs g, sprung between studsjj. I I

O is the punch bed-plate, having side projections or lugs, m an, which are seated in and traverse the horizontal slots 00 x in the sides A A. I The bed-plate O is also provided with a depression, a, in its upper face, into which wood, leather, lead, or other material is fitted for the punch h, when in operation, to out against. Upon the lower central face of said bed-plate G is the bifurcated lug j, to which is pivoted one end of the arm is, the other end of 8 5 saidarm It being provided with. the oblong hook r, which engages the crank r of the crankshaft D, by which the machineis operated. The crank-shaft D serves the double purpose of reciprocating the bed-plate O, with the 0 punch-standard B thereto attached, and by head draws the material upon the bed-plate C) releasing such punch, thereby gaging the distances between the punched holes. By moving the screw f forward or back in the slot E the distances between the punched holes can be regulated as desired.

The method I have invented of regulating the number of holes to be punched at any time is as follows: On the forward leg of the side nearest the operator I journal the ratchetwheel H, which has in its periphery a series of onehundred ratchets and the tongue projection 0, immediately below which, on the front face of the wheel H, is the lug n. A clamp, p, with its single notch z, I attach to any de sired part of the'periphery of the wheel. The surface of the wheel H is divided into ten equal parts of ten ratchets each, the said divisions being indicated on the face of the wheel. Immediatelyunder the upper part of the wheel H and against the side A is screwed or riveted theT-shaped iron Z, which moves on said screw or rivet, but not freely enough to change its position by its own weight. This T-shaped iron has on its upper edge the semicircular projection m, immediately above which,and in the same plane therewith,is the pawl q, riveted loosely to the side A. Attached to one'of the arms of the wheel H is one end of a coil-spring, .3,-saidwspringbeing coiled around the axle of thewheel H, between said wheel and the side A, and having the other end attached to the side A.

The strip of leather or other material to be punched is introduced under the feed-clamp 9 and brought. along beneath the guide consisting of the upper part, c, and the adjustable'side piece, 0, under the punch h at the point. for the first hole or set of holes. Then by the turning of the crank-shaft D the cams y on said crank-shaft operating against the end of the arms '10 of the punch-standard B, the said standardworking upon its pivot at c is thrown=forward and downward, forcing the punchh throughthe material to be punched. The pieces punched out will flow off down the-chute b. The. punch remains in such position while the bed-plate O is drawn bythe arm is and crank r back to the point where the forward arm, c, of the punch-standard B encounters the trip c, when such encounter tilts the standard, carrying its arms 10 downward,

and raises the point of the arm 12 over the trip 6, and thereby removes the punch from contact with the material to be punched, such material having been-drawn back by the punch h the proper interval between the holes punched. As the'crank is further revolved,

the bed-plate O and standard B are progressed forward along the strap to be punched to the proper position for the next hole or set of holes. In its progress the point of the pawl d engages one of the notches on the wheel H and pushes it forward one notch, and the point of thepawl qholds said wheel in the position in which it is left by the pawl d. 'The operation is then continued until the desired number of holes are punched. WVhen this result is reached, (the counting-wheel H having been properly set,) the clamp p is immediately in front of the line of movement of the pawl d,

which in such forward movement encounters the notch z on said clamp, and throws the forward end thereof against the T-shaped iron Z,which in its turn revolves its projection m against the pawl q, and holds it from contact with the wheel H until the pawl d moves back out of the notch .2, when the spring 3, coming into action, reverses the movement of the wheel H. The lug n on the face of such wheel strikes against the end of the T-shaped iron nearest to itand throws it back from its contact with the pawl q, the latter being knocked into po sition by the tooth 0, and at the next movement I of the punch the point of the pawl d, starts again to count at the cipher on the wheel. The wheel H is actuated and revolved one ratchet at each forward motion of the bed-plate O by means of the pawl 61, pivoted to the side of such bed-plate, and which engages the ratehets on the periphery of the wheel H.
