COMBINATION TOOL.

Specification of Letters Patent.

Patented March 30, 1909.

Application lfiled March 26, 1908. Serial No. 423,404.

To all whom 'it may concern:

Be it known that I, HARRY E. SHAUL, a citizen of the United States, residing at Pescadero, in the county of San Mateo and State of California, have invented a new and useful Combination-Tool, of which the following is a specification.

My invention relates to mechanics tools, and the object is to provide a combination tool in which various forms of wrenches, drill ratchets, center punches etc. are all contained and combined in the handiest possible manner.

In the accompanying drawing,*Figure 1 is a partlysectional side elevation of my combination tool shown as in use as a drill ratchet. Fig. 2 is an enlarged bottom end view of the drill and the means holding it in Fig. 1. Fig. 3 is an enlarged sectional view on line a-a in Fig. 1 with the drill removed. Fig. 4 is a right hand side elevation of the tool shown in a portion of Fig. 1. Fig. 5 is a top view of the tool shown in Fig. 1. Fig. 6 is a side view of the tool changed into an open-ended wrench. Fig. 7 is the tool converted into a monkey wrench and showing also how certain other parts may be put together for various purposes. Fig. S is a sectional top view on the line b-b in Fig. 1, and Fig. 9 is a detail view of a ring by which dogs of the ratchet are alternately held 1 e.

Referring` to the drawing by reference numerals, 1 designates a wrench head having a fixed jaw 2, and a large opening 6 through it, with a guiding bar 3 for a movable jaw 4 to slide on and be further guided by ledges 5 in the head. Each jaw has a longitudinal groove 7 and at the sides thereofl corrugated faces 8 for holding firmly any object placed between the jaws. The movable aw is moved to and from the ixed jaw by a thumb screw 9 threaded through it and journaled in the head 1, in which it is retained by a pin 10.

When the tool is used as an open-ended wrench, the forked end 11 of the handle 12 is inserted in the top of the head 1 and retained therein by a thumb-screw 13, which in that case `acts as a pin, and is held in place by a cotter pin 14 passed through it. And for converting the wrench into a monkey wrench (as in Fig. 7) said handle is inserted into two cavities 15 in the movable jaw, and is there retained by a thumb-screw 16 passed through it as a pin and having a few threads 17 retaining it in the jaw. Said handle 12 is hollow at 18 to make it light and is formed with a slot 19 in which a center punch 20 is foldably friction-held on a pivot 21. The end of the tubular portion of the handle is reduced to a four-cornered socket 22, in which the one end of an extension bar 23 may be held by a thumb pin 24, as to the right in Fig. 7, when extra leverage is desired in the use of the wrench.

When the wrench is to be used as a socket wrench, or as a drill chuck, (for the latter see Figs. 1 and 2) the extension bar 23 nn be placed as in the upper part of Fig. 7, w ere the screw 13 is threaded through it and holds it directly above the opening between the jaws; and the spindle 25 of a drill ratchet 26 is inserted and held by a pin 27 in the socket 2S of the extension bar, and the ratchet is turned by the handle 12, (see Fig. 5) whose fork 11 is held by the thumb screw 16 in a straddling engagement with an extension 29 of the ratchet. In cases where the extension bar is not thus needed it may be used for a second handle, as to the left in Fig. 5, where it is held by the pin 24 in a socket 30 of the ratchet, or it may be used for an extension of handle 12, as to the right in Fig. 7.

lVhenever the tool is operated by the ratchet and the extension bar is not used be` tween the ratchet and the head 1, the rectangular hollow end 31 of the ratchet spindle 25 is inserted in the upper end of the head 1 and there engaged by the threads of the screw 13, by which it is adjusted in line with the opening between the jaws 2 and 4. If the wrench head should be needed for other work during drilling, the handle 12 may o with it, and drills with rectangular shan is may be inserted directly into the end of the socket 31 of the spindle, and the extension bar alone may be used for a handle, as to the left in Fig. 5, or if the wrench is not needed at the time, the handle 12 may be used as in Fig. 5 and the extension bar and the wrench head may be idle.

The ratchet is of the type having its spindle 25 rotated in either direction by a ratchet wheel 32 fixed on it and two dogs 33, 34 pivoted at 35 and normally pressed by springs 36 into engagement with the ratchet teeth 37, which are of the double-faced kind so as to be pushed in one direction by the one do and in the reverse direction by the other og. Guided to revolve about the tails 38 of the dogs is a ring 39 (see Fig; 9) having an internal notch 40, which when turned in the path of either one of the tails, allows the adjacent spring 36 to swing that tail so far outward that the dog will engage and operate the ratchet wheel; ,and if the ring is turned in the opposite direction the other dog will operate the wheel, and in either case the part of the ring opposite the notch iolds one dog idle.

The upper end of the spindle 25 is pro vided with internal screw threads 41, in which engage a -feed screw 42 having the usual center point 43 and a sleeve 44 extending downward upon the spindle, where it may be grasped by one hand for turning the feed screw, or the latter may be turned by a loose pin (not shown) inserted in the holes 45 in the head end of the screw.

vWhen the center punch 2O is to be used it is turned into the position shown in full lines in l.

Having thus described my invention, what I claim is 1. A combination tool comprising in combination, a wrench head having a iixed jaw and a large opening with a bar traversing the same, a movable jaw slidable on the bar, a screw -iournaled in the head and engaging the movable aw to move it to and from the fixed j aw, said head having its opening extended out through its top oiposite from the jaws and said movable jaw iaving two cavities in the side opposite from its teeth, a handle having one end bifurcated into a fork or two arms adapted for insertion alternatelyT in the cavities in the movable jaw and at right angle therewith in the opening in the head of the wrench, and means for holding the handle detachably secured in said positions.

2. A combination tool comprising incombination, a wrench having a head 'with one fixed and one movable jaw, each with a groove adapted to coact with the groove of the other jaw in holding the shank of a drill, said head having in its top an elongated opening with a feed screw ex lending longitudinally therethrough, a ratchet having the lower end of its spindle adapted to go into the opening in the top of the wrench head, and provided with a threaded hole for the feed screw, said ratchet having the extension 29 with the pin 16 through it, and the handle having a forked end with holes through it for the reception of the pin 16, and for the feed screw according as the use of the tool may require.

S. A combination tool com rising in combination, a wrench having a ead with one fixed, and one movable jaw, each with a groove adapted to coact with the groove of the other j aw in holding the shank of a drill, said head having inV its top an elongated opening with a feed screw extending longitudinally therethrough, a ratchet having the lower end of its spindle adapted to go into the opening in the top of the wrench head, and provided with a threaded hole for the feed screw, said ratchet having the extension 29 with the pin 16 through it, the handle having a fori-red end with holes through it for the reception of the pin i6, and for the feed screw according as the use of the tool may require, and the extension bar 23 adapted for insertion and use in the various positions shown and described.

In testimony whereof I aflix my signature, in presence of two witnesses.

HARRY E. SHAUL.
