COMBINATION BOLT AND NUT CUTTER.

Specification of Letters Patent.

Patented Dec. 10, 1907.

Application filed September 18. 1907. Serial No. 393.490.

To'all whom it may concern:

Be it known that I, JAooB BAOKSCI-IEIDER, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Combination Bolt and Nut Cutters; 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 it appertains to make and use the same.

My invention has for its object to provide an improved combination bolt and nut cutter, and to this end it consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

Especially this invention relates to the improvement of bolt cutters of the general character disclosed in Letters Patent 236,695, issued to H. K. Porter of date January 18, 1881, and consists in providing such a bolt cutter with an attachment or improvement adapting it for use in cutting or splitting nuts.

The invention applied as above indicated is shown in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a view in plan, showing my invention applied to the said bolt cutter. Fig. 2 is a view corresponding to Fig. 1, but with some parts broken away, and illustrating the parts in different position; and Fig. 3 is a vertical section taken on the line 90 00 of Fig. 1. p

The construction of the bolt cutter, briefly described, is as follows: Long handle levers 1 are provided with interlapped lugs 2 that are pivotally connected by a nutted bolt 3. Cutting jaws 4 are pivotally connected at 5 to laterally spaced tie bars 6, between which the said jaws are held. The inner ends of the jaws 4 are pivotally connected at 7 to the forwardly projecting ends of supplemental levers 8 which, as shown, are adjustably connected to the handle levers 1 by nuttedbolts 9.

In applying my improved nut cutting attachment to the tool above described, I employ a chisel 10, the inner end of which is piv, otally connected to the pivot bolt 3 before noted. At its forwardly projecting end, this chisel is provided with a cutting edge lland with a projecting guide finger 12. The guide finger .12 works with freedom for endwise movement between the two tie bars 6 and between the intermediate pivoted portions of the cutting jaws 1, and thus guides the cutting edge 1 1 for approximately true endwise movement toward and away from the adjacent edge of the alined tie bar 6. This tie bar 6 which is alined with the chisel 11 affords .an

. anvil or cutting abutment against which the nut is pressed while being cut or split by the chisel point '11. The edge portion of this anvil connecting tie bar is preferably thickened slightly and beveled inward, as shown at 6". This bevel prevents the nut from being crowded outward while it is being cut by the chisel point 11. As is evident, under pivotal movements of the handle bars 1, the pivot bolt 3 is moved forward and rearward in respect to the-pivot 7so that the chisel is given an endwise movement toward and from the cooperating abutment 6 A nut cutting or splitting attachment of the kind above described will be found useful in a very great many different places and is especially serviceable for splitting the nuts of bolts used to connect tires to the rims of vehicle wheels. The heads of these bolts are usually countersunk into the tire and the nuts are clamped against and sometimes more or less embedded within the wheel rim. lVhen the bolts'or nuts are rusted it is usually impossible to turn the nuts off from the bolts because the bolts will turn in the tire. By this improved nut cutting attachment such nuts may be readily cut or split, and hence easily removed from the bolts. The nut cut ting attachment above described adds but very slightly to the cost of the bolt cutter. The cutting jaws 4:, as is well known, are especially adapted for use in cutting the bolts.

The so-called supplemental levers 8, so far as this invention is concerned, constitute parts of the handle bars or levers 1 and might be formed integral therewith.

What I claim is:

1. The combination with a pair of cutting jaws and a pair of laterally spaced tie bars to which said jaws are pivoted, of a pair of works between two tie bars and the said two handle bars pivotally connected to said aws, cutting aws, substantially as described. 10 and a chisel connected by a common pivot to In testimony whereof I affiX my signature said two handle bars at a point between the in presence of two witnesses.
