To ALL WHoM 1T MAY conceals:-

Be it known that I, JosIAn Ynssnn, of Berrysburg, inthe county of Dauphin, 'and State of Pennsylvania, have invented anew and useful Improvement in Machines for Cutting and Punching Fly-Net Straps, Sie.; and I do hereby declare the following .to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which- I Figure 1 is a rear elevation of my improved machine.

Figure 2 is a side view of one of the cuttersdetached.

Figure 3 is a plan view of the punch-bed plate, with Athe guide-plate and gauge attached, and

Figures l and 6 are bottom views of the punch and cutter-bits or stocks, detached.

Similar letters of reference denote corresponding parts in all the igures.

My invention relates to the construction of the cutters, and to the manner of mounting and securing them in the adjustable bit or stock; to the manner of securing the punches, and to the construction of the metallic bed-plate, upon which the punches operate, whereby it is adapted to receive guides lfor diii'erent-sized straps,.as hereinafter explained. I

To enable others to understand and use my invention, I will describe it with reference to the drawings, in whichv A represents a bed or frame-plate, of any desired size or form to adapt it to the size ofmachines, andthe number of cutters to be mounted thereon, and also tobe secured to the bench or table upon which it is'to be used. B B are uprightsv or standards mounted inthe bed-plate A, and provided upon their adjacent faces with the salient angles or ways Z1 upon which the bit or stock C, lcorrespondingly notched or recessed at its' opp.o site ends, moves or is guided in being raised and depressed. The standard B is`made somewhat taller; than the standard B', and is slotted at its upper end, 'to receive one end of a lever, D, which is pivotedto'and has its fulcrum in said standards, as shown at a, g. 1. c c arelinks, pivoted at their lower ends to the bit or 'stock U, on the opposite sides thereof, Vand at the other or upper ends to the lever D. The bit or stock C is made in form substantially as represented in the .bottom views, figs. 4 and 5,'the notches or grooves b', in. the end thereof, being such as to correspond with the form of the ways upon which the bit works. Said bit is mortised or recessed, as shown at-d, iig. 5,'toreceive the knives or cutters, and the keys or blocks by means of which the knives are spaced or set lat the required distance apart. One or both of the ends of the mortise are formed with an inclined face, to adapt them to receive a wedge or wedge-shaped key, by t-he lateral adjustment of which in the block, by means of ono or more set-screws, E, the knives are adjusted and tightly held, or released for removal, as desired. The knives e are made in for-m represented in iig'. 2; that is, with the cutting edge extended, v

by being rounded or inclined, in such manner that while supported in a vertical bit they will present an inclined edge similar to 4that presented where the opcrationof cutting is performed by hand. In fig. 1 the bit and cutters arc'represent'ed as slightly raised, in order to better show the'arrangement of the guide end bed-plate. The bed-plate F, wherevthe cutters are used, should be made of leather or other suitable material, which will receive and prptect and steady the points of thc cutters, which are necessarily formed of very thin metal. G is a guide plate, secured to the bed-piece A in front of the cutters, which serves to hold the leather down and properly present it to the cutters. E is a thumb-screw passing vthrough standard B, which, when the bit and cutters are properly adjpsted, serves to hold them-down to their work. In iig. 4 I have shown the bitas especially adapted to the reception of the punches ff, though it will be obvious that thesame bit may be adapted to be used with either the knives or punches. In this figure the greater-length of the mortise is transversely of the block, and

the two punches are held in place therein by meansot` the set-screw E. The bed-plate F,yig. 3, adapted for use with the punches, 'is made of metal, and is provided with means for readily attaching and detaching the perforated or slotted guide G', of which there may be any desired number, adapted to the various widths of strap to be punched. The means of securing said guides to the bed-plate are shown, in'this instance, as con sisting of four set-screws; but it will be evident that parallel ways, similar to those shown at a', for uniting thc bed-platel and bed-pieceA, may be used with asinglc set-screw, or its equivalent, for holding the strap-guides in place. These bed-plates FF are readily removed from the frame-plate A, and substituted one for the other, by being inserted into the dove-tail *groove ac in said' plate A, or the equivalent thereof, adapted to receive and retain them. 7L is an adjustable gauge or aangle-iron, slotted at h1, and adjusted and held by set-screw z'. Said gauge is provided with an arm, h2, projecting over the path of the strap as it is drawn through the guide- Way underneath the punches, which serves, by its position or adjustment, to indicate to the eye ofthe attendant.

the proper distance between the perforations in the strap. Instead of this gauge-plate a series of holes may be made in the bed-plate F', and an adjustable pin used therein, for the same purpose. It will be readily understood that the number of knives and their distance apart may be readily varied by varying the thickness ofthe spacing-keys, by the insertion of thin additional keys or slips of metal, as desired. The distance between the punches may be varied in the same manner.

In operation the cutter-bit is held down upon or in close proximity to the frame-plate A by means of the set-screw, as described, the points of the cutters entering and being steadied inthe bed-plate F, and the strap inserted underneath the guide-plate G is drawn through and cut in a manner that will be readily understood. In the operation of punching the straps, the bed-plate F with its perforated guides is substitutechand the bitis left free to be moved up and down on its Ways or guides, operated by lever D, and the holes are punched therein in pairs in the usualway, and the distance between the pairs regulated'in the manner explained.

Having now described the construction and operation of mv invention, what I claim, and desire to secure by Letters Patent, is-' 1. The construction of the knives or cutters e, with the inclined cutting edge, substantially as described.

2. The adjustment oi' the cutter-bit or stock, by means of the lever, as described.

3. The manner of securing the knives 'and spacingkeys, by means of set-screws and wedge, as described.

4. The two punches ff, arranged in the bit or stock, and secured therein by the setscrew, as described, for punching the holes in the strap in pairs, as set forth.

5. The metal bed-plate Ff, adapted to receive the perforated guides for various-sized straps, substantially as and for the purpose set forth.
