COMBINATION-TOOL.

Specification of Letters Patent.

Patented July 14, 1908.

Application filed March 16, 1907. Serial No. 362,641.

provements in Combination-Tools, of which the following is a specification.

My invention relates to a combination tool of which an adjustable alligator wrench forms the principal part and. the object thereof is to provide a combination tool which is adapted to a variety of uses. I accomplish this object by the tool described herein and illustrated in the accompanying drawings in which:

Figure 1- is a side elevation with parts broken away for clearness in illustration of the principal parts of my combination tool. Fig. 2 is a front end elevation. Fig. 3* is an edge elevation. Fig. 4 is a fragmentary side elevation of a portion of the main tool combined with an auxiliary. Fig. 5 is a perspective view of one of the auxiliary tools.

In the drawings 6 and 7 are the main jaws of my improved adjustable alligator wrench which are pivotally secured together near the rear end thereof by the rivet 8. At the rear of their pivotal connection the opposing faces of the rear ends of these jaws at 9 form flat-faced pliers and are sharpened at 9 to form a wire cutter. The jaw 7 at the rear of pivot 8 is a little bit longer than the jaw 6 and the extreme end is sharpened at 10 to form a screw driver. The inner face of the front end of aw 7 is provided with teeth 11 for use in turning a pipe. A hammer head 12 having a bifurcated shank 13 is secured to the front end of jaw 7 at the rear of the teeth therein. This hammer head is provided with nail pulling claws 14. The front end of jaw 6 passing through the shank of the hammer head within said shank is provid ed with a socket 15 in which is housed one end of a spring 16 which normally presses the front ends ofjaws 6 and 7 apart. The other end of the spring is, housed in the socket in jaw 7. Adjacent to the pivot 8, jaw 6 is provided with a yoke 17 secured thereto through which passes the shank 18 of the adjusting wedge 19 which is longitudinally movable along the top of jaw 6 to adjust the width of the opening between the front ends of jaws 6 and 7 thereby giving a considerable range of adjustment to the jaws of the alligator wrench. As best shown in Fig. 1, the top of this wedge is on a slant and the inner surface of the hammer head within the shank has nearly the same bevel as the wedge but running in a reverse direction. Mounted on the top of the shank of the wedge is a dog 20, the arms 21 of which engage with teeth 22 in the top of jaw 6 to prevent the wedge from slipping rearwardly, thereby holding the front end of jaws 6 and 7 in whatever position the wedge is placed. A spring 23 normally holds the dog in a position to engage said teeth. It Wlll be ob served that as the wedge is pushed forward the dog will ride over the teeth without attention, but on the rearward movement of the wedge the dog must be thrown forward so that the arms thereof will not engage with the teeth.

In Figs. 4 and 5 I have shown an auxiliary tool 24 which has in the outer end thereof a notch 24 of the configuration to fit upon the nut of a bolt. In said auxiliary tool I have provided an aperture 25 therethrough which forms a die for cutting threads. I also provide in said tool an aperture 26 in which may be received the end of a tap. Said auxiliary tool is provided with a stud 27 in one edge thereof which-stud is adapted to enter a socket 28 in aw 6, and with lugs 29 which project beyond the opposite edge thereof and straddle jaw 7. When it is desired to use said auxiliary tool, wedge 19 is drawn rearwardly so that the front ends of jaws 6 and 7 can separate far enough to permit stud 27 to enter socket 28 when the wedge is ushed forward to the position shown in ig. 4 when the auxiliary tool is firmly united to the main tool. It will be observed that the length of the auxiliary tool is such that one end will pass within the shank of the hammer, which will hold it against lateral movement, and that the other end thereof is held against lateral movement by the lugs and pin.

Having described my invention what I claim is:

1. An alligator wrench composed of separate jaws pivotally united at one end, one of said jaws being provided with a series of serrations, a collar surrounding both of said pivoted jaws, a wedge slidably mounted between said collar and one of said pivoted jaws, and a pivoted spring-pressed do on the wedge adapted to be moved into and out of engagement with the serrations on said jaw to lock the wedge and jaw against relative movement.

2. An alligator wrench composed of sepa rate jaws ivotally united at one end, one of said jaws eing provided with a series of serrations, a collar surrounding both of said pivoted aws, a wedge slidably mounted between said collar and one of said pivoted jaws, and a pivoted dog on the wedge normally spring-pressed into engagement with the serrations on said jaw to lock the wedge and jaw against relative movement.

3. An alligator wrench composed of separate aws pivotally mounted at one end, one of said jaws being provided with a series of serrations, a collar surrounding both of said pivoted jaws, a wedge slidably mounted between said collar and one of said pivoted jaws, and a pivoted dog on the wedge nor mally spring-pressed into engagement with the serrations on said jaw to lock the wedge and jaw against relative movement, in one direction only.

In witness that I claim the foregoing I have hereunto subscribed my name this 9th day of March, 1907.

EMIL SUTHERLAND.
