WITNESSES A Patented June It), 1930 warren STATES BERT WILLIAMSON, F MCKEESPORT, PENNSYLVANIA COMBINATION CLEAVER, KNIFE, AND SAW Application filed May 25, 1926.

A further object is to provide a novel means for holding and tensioning the saw.

A still further object of the invention resides in the novel form of foldable handle.

Other objects and advantages reside in certain novel features of the construction, ar-

rangement and combination of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being bad to the accompanying drawings forming a part of this specification, and in which Figure 1 is a view in side elevation showing the invention when used as a knife,

Figure 2 illustrates the same when used as a saw,

Figure 3 is a sectional View taken on the line 3--3 of Figure 1,

Figure 4 is a fragmentary detail perspeclive view showing the foldable handle, and

Figure 5 is a fragmentary view in section showing how the handle is locked in open position.

Referring to the drawings the numeral 1 designates a blade which is made of steel or other suitable material and which possesses some degree of resiliency or flexibility transversely although sulhciently rigid and stiff to enable it to serve effectively as a knife. F or the major portion of its length the blade tapers from a slightly blunt edge 2 to a knife or cutting edge 3. The rearward portion of the blade is provided with a tapered extensi on 4 which projects beyond the blunt edge in a direction opposite from the direction in which the edge 3 extends to form an entering wedge when the saw 12 hereinafter described is used. The tension also serves to stiffen and strengthen the rearward portion of the blade to adapt it to serve as a cleaver, the edge of which is designated at 4*.

Serial No. 111,592.

-r. its ends the blade provided with lugs (3 and 7 having laterally extending threaded pins 8 and 9. The pins 8 and 9 are designed to co-act with the slots 10 and 11 of the saw blade 12.

The end of the blade on which the extension 4 is provided has integrally formed therewith or suitably connected thereto a channelshaped handle member 15 which is adapted to be gripped when the device is used as a knive, cleaver or other form of cutter. In order to anaptthe device for use as a saw an auxiliary handle member 20 is pivotally connected, as at 21, to the channelshaped handle member 18 and may be swung into and housed entirely within the handle member 18 or may be extended at right angles therefrom. When in its extended or operative position the auxiliary handle member 20 is held against pivotal movement by means of blocks 22 slidably received in recesses 28 in the handle member 20 and engageable with the handle bracket or member 15. Any suitable means may be provided for preventing entire displacement of the blocks 22 from their recesses and they may be suitably connected or secured to the ends of an expansible coil spring 24 which serves to project the blocks 22 to a position wherein they engage the handle member 15. In operation when it is desirable to apply a saw blade the blade 1 is flexed or bent transversely to bring the studs slightly nearer to each other and permit their insertion in the slots 10 and 11 of the saw blade. When the blade 1 is released the studs 9 and 10 are moved apart under the resilient action of the blade 1 and these studs engage the outer end walls of the slots of the saw blade to tension and hold the saw blade in position. WVing nuts may be threaded on the studs 9 and 10 to prevent lateral displace ment of the saw blade. The handle is adapted to be used to advantage with both the saw and cutter or knife.

By tapering the extension 4 and causing it to merge into the bod) of the blade the sawing of heavy bones is facilitated and the blade 1 is also given sufficient weight and strength to adapt it for use as a cleaver. The wedge-like formation of this extension 4 adapts it to enter the space formed by the saw blade.

I claim:

1. A tool of the class described comprising a blade, the major portion of the length of which is in the form of a knife, the remainder of the blade being thickened intermediate its width to form a cleaver-like structure at one end, said thickened portion being tapered transversely toward its opposite edges, one edge forming a cutter and the other an entering wedge, the knife portion of the blade'being tapered transversely from a blunt edge at one side to a cutting edge at the other and a handle connected with said blade.

A tool of the class described comprising a blade, the major portion of the length of which is in the form of a knife, the re mainder of the blade being thickened intermediate its width to form a cleaver-like structure at one end said thickened portion being tapered transversely toward its opposite edges, one edge forming a cutter and the other an entering wedge, the knife portion of the bladebeing tapered transversely from a blunt edge at one side to a cutting edge at the other, said blade having integral lugs adjacent its ends extending edge-wise therefrom said lugs being provided with studs extending from the inner faces thereof, and a saw blade having slots cooperable with the studs to hold the saw blade engaged with the first mentioned blade.

BERT WILLIAMSON.
