J. NEUMAIER COMBINATION TOOL Filed March 26, 19823 WITNESS ATTORNEY Patented Apr. 8, 1924.

JOHN NEUMAIER, OF PRAIRIE DU SAG, WISCONSIN.

COMBINATION TOOL.

Application filed March 26, 1923.

T aZZ whom it may concern:

Be it known that I, JOHN NEUMAIER, a citizen of the United States, residing at Prairie du Sac, in the county of Sank and State of WVisconsin, have invented new and useful Improvements in Combination Tools, of which the following is a specification.

This invention relates to a tool, the general object of the invention being to provide means for extracting, inserting and spreading cotter pins.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described,-illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure l is a side view of the tool.

Figure 2 is an end view.

Figures 3, i and 5 are views showing how it is used.

Figure 6 is a section on line 66 of Fig ure 1. As shown in these views the device consists of the pair of members 1 and 2 pivotally connected together and each of which consists of a handle part 3 and a jaw part i. Each jaw part is provided with a circular recess provided with teeth and the end of one jaw member tapers off to a point, as shown at 5, with its inner edge grooved, as at 6, while the end of the other jaw member is of rectangular shape in cross section and contains a threaded bore 7 and has a groove 8 on its inner edge. A wedge member 9 has a threaded pin 10 thereon for engaging the threaded bore 7. The device may be formed with wire cutters 11 and the jaw members may be provided with transverse grooves 12 which form a wire holder. The wedge serves the. purpose as a fulcrum and also as a spreader. When a cotter pin is to be extracted the wedge is placed upon the body from which the pin is to be removed, as shown in Figure 3, and then the tapered jaw engages the eye of the pin to pull the same from the hole. When a cotter pin is to be inserted the wedge is turned, as shown Serial No. 627,768.

in Figure 4:, the pin being held in the grooves of the jaws with its end projecting so that it can be inserted into the hole. The grooves are roughened, as shown. The pins are spreaded by the fulcrum and one of the handle parts may be tapered, as shown at 13, for the purpose of turning the pin so that the extractor can engage it.

From the foregoing it will be seen that cotter pins can be easily and quickly put in place and removed by this tool.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall with in the scope of the appended claims.

What I claim is 1. A tool of the class described consisting of a pair of jaw members, the end of each jaw member being extended with the extended part of one member tapered, said extended parts having grooves in their abutting faces for holding a cotter pin, the untapered part having a threaded bore therein and a wedge having a threaded projection thereon for engaging said bore.

2. A tool of the class described comprising a pair of members pivotally connected to gether, each member consisting of a handle part and a jaw part, the ends of the jaw parts being extended with the inner faces of the extensions grooved, one extension being of tapered shape and the other of rectangular shape and having a threaded bore there in, a wedge member, and a threaded projection thereon engaging the bore.

3. A tool of the class described compris ing a pair of members pivotally connected together, each member consisting of a handle part and a jaw part, the ends of the jaw parts being extended with the inner faces of the extensions grooved, one extension being of tapered shape and the other of rectangular shape and having a threaded bore therein, a wedge member, a threaded projection thereon engaging the bore, one of the handle parts being of tapered shape and wire cutters formed on the members.

In testimony whereof I afiix my signature.

JOHN NEUMAIER.
