BOLT AND NUT CUTTER.

SPECIFICATION forming part of Letters Patent No.

b(10,181, dated September 30, 1902.

Application filed May 19, 1902. Serial No. 108,044. (No model.)

To'a/ZL whom t may concern:

Beit known that I, WILLIAM B. Cartones,

embodiment in the accompanying drawings,

in which- Figure 1 is a perspective view of a complete bolt and nut cutter; Fig.2,an enlarged broken section parallel with a side of the cuttinghead, the section being taken as indicated at line 2 of Fig. 6; Fig. 3, an end view of the cutting-head; Figs. 4, 5, and 6, sections taken as indicated atthe corresponding lines of Fig. 2, and Fig. '7 a viewof a block employed in the adjustment of the reciprocable holt-cutting knife. Y

The preferred construction is as follows: A represents a blade or cutter frame comprising members A A2, formed from sheet metal; B, a block secured in theframe A at the free end vthereof and supplied with a'bolt-cutting blade havingl a sharp edge d parallelwith a side of the frame and provided also with a dull nut-bearing edge ct,perpendicnlar thereto; C, areciprocable blade-attaching block movable longitudinally 0f the frame; C', a bolt-cutting blade having a sharp cutting edge b directly opposed to the blade aj C2, a bolt cutting or splitting blade having a sharp cutting edge b directly opposed to the nut-bearing edge ed; D, short links pivotally connected with the frame member A', and Dflevers having enlarged ends slotted to receive thev rear ends of the links D and lugs or ears c, with which the block C is provided at its rear end or base. The links are connected by pivots cl with the frame member A and by pivots d with the levers D', and the levers are connected by pivots d2 with the base of the block C.

The frame member A is integrally formed from sheet metal and is of general U shape,

kaffording sidesfand a connecting-web f', the latter constituting the end of theimplement. The sidesf are spaced to receive the block C between them and are provided with longitudinal slots or openingsfZ, one of which has an enlargement f5 at its rear portion. The rear extremities of the sides fare provided with laterally-projecting ears f4, corresponding sets of which receive between them the enlargedfront ends of the links D. In the operation of stamping out or blanking the frame member A the lateral edges are provided with recesses which produce,after forming, the cut-away or sheared corners f5.

The frame member Azcom prises a U-shaped strip with parallel lateral edges and integrally-stamped lateralvlugs g, which pass through corresponding perforations, with which the member A' is provided, and serve as rivets. Thus the member A2 is in reality a U -shaped spacing-piece, havingsidesg and a web g2, the latter lying adjacent to the inner surface of the web f.` The web g2 reinforces the end of the frame, and the complete member A2 irmly connects the sides of the member A' and affords with the member A a box-frame open at the top and bottom (at the slots f2) and open at the rear end to receive the block C. As shown in Fig. 4, the sides g' form guides for the lateral edges of the block C and are so located with relation to the longitudinal walls of the slots f2 that flanges 7L are left to form top and bottom guides for said block C. V'The block O has its upper and lower front portions cut away, leaving a projection 7c of reduced cross-section, at the base of which are transverse shoulders 7c' k2. The blade C"a is formed with a shoulder 7c3, which ahuts against the end of the projection hand it has a rearward extension 7.a", which'abuts against't'nel shoulder 7s'. The extensions 7c 7e" are provided with registering, vertical slots 795. The blade C ahuts at its base end against the shoulder 702 and has a threaded perforation receivinga screw 7o, extending through the slots 705. When the screw is tightened, a connection is formed capable of transmitting great compressive force from the levers. The bolt-knives are subjected to great wear and must be frequently ground, while there is little wear upon the nut-blades. The construction permits the IOO bolt-knife C to be adjusted as required, a wedge or block Z of 4desired thickness being inserted between the rear end of the blade and the shoulder k2. To hold the block in place, the shoulder 7a2 is undercut and the block is provided with a lip, as shown in Fig. 7. V

The blade B fits between the sides g of the member'A2 andghas top and bottomprojections ,Which lit in the slots fz of the top and bottom platesf. Said blade is inserted at the enlarged opening f3 and moved forward into position, being secured by a screw m. The blade C' has its lateral edges in contact with the sides g' and has a projection n, fitting snugly between the flanges h. Said blade is inserted from the rear and then raised into position. The blade C2 has its lateral edges in contact with the sides g and has a projection n', which fits su ugly between the flanges h. Said blade is inserted from the rear and then raised into position, the block C being inserted lastly and the screw inserted to secure the blades thereto.

The manner of using the implement will be readily understood from the foregoing detailed description. When a bolt is to be clipped, the implement is placed so that the bolt projects between the cutting edges ct and l). When a nut is to be split, the implement is reversed, so that the vertical edges ct b engage the nut. In the operation of splitting the nut the blunt edge d acts as a bearing, while .the sharp edge b', cuts into the nut approximately to the bolt and causes the walls of the cut to separate, the two halves of the nut swinging about the bearing a'.

An implement constructed as described is capable of withstanding great strain,is cheap, and thoroughly efficient.

Changes in minor details of construction within the spirit of my invention may be made. Hence no undue limitation should be understood from the foregoing detailed descript-ion. For instance, a less desirable but still valuable construction within the spirit A of my invention would result if either of the frame members A and A2 were altered so as to be no longer integral, and even if both were thus altered valuable featuresof the invention would remain. l

What I regard as new, and desire to secure by Letters Patent, is-

1. In an implement of the character described, a cutter-frame comprising suitablyspaced sheet-metal side plates vconnected at one end, and sheet-metal connection joining said side plates rigidly together and formingv therewith a box open at one end, for the purpose set forth.
