TOOL HOLDER.

Application filed December My invention relates to devices for bolding inserted tools as a class.

The object of my invention is to provide such a device primarily for holding an inserted wrench jaw of special form, but also to hold a hammer head, screw driver and various other tools of like form. These tools are inserted in an oscillating member mounted in the end of the handle. These objects, as well as other advantages, I attain by the construction, combination and arrangement of parts illustrated in the accompanying drawings which form a part hereof.

Fig. I is a plan view of the device, partly in section. with wrench jaw inserted in holding member.

Fig. 11 is a side view of the same. i

Fig. H1 is a sectional view of the socket in the holding member.

F IV is an illustration of a hammer read as inserted in the holding member.

Like characters refer to like parts in the views.

A handle of convenient form and dimensions is provided. The handle is composed of two like members 12 which are secured to each other by screws 3 and when in po sition form a casing for the parts to be described. In the upper end of the handle a holding member 4 is pivoted in bearings The member 4 has a wedge-shaped socket adapted to receive the arm 7 ot a tool, such as the arm of the wrench jaw 8 or the arm 9 of the hammer head 10. The arm has a small recess in the edge as at 11. A pin 12 is transversely positioned in the socket 6 to engage the arm in its recess 11 and retain the arm in the socket. The pin is outwardly actuated by a coil spring 13, the tension of which is sufficient to retain the pin in the recess 11 when opposed and to allow the arm to press the pin inwardly when inserted to operating position or withdrawn. The lower rounded portion of the member 4 has peripheral ratchet teeth 14 along its edge. The member 4 is positioned to oscillate on its pivot sufiiciently to allow its socket to as sunre a predetermined radial position between that of opposing positions transverse to the handle. Below the member 4 is a rod 15, vertically movable through an opening 16 in the casing in sliding engagement with the sides thereof, the opening being in the upper portion of the handle. The rod is also rotatable in said bearings. On the up- 14, 1925. Serial No. 75,308.

per end of the rod is an integral ratchet or pawl 1?, provided with teeth l7" along its upper edge, in alinement to engage the teeth 14 of the member 4. Below the ratchet on the rod are opposing finger projections 18. The casing members have openings 19 to allow access to the projections 18. The casing members have a vertical recess 20 in their lower portion, within which a coil spring 21 is placed. The lower end 22 ot' the rod 15 engages the upper end of the spring. Above the rod end 22 the rod has a circumferential groove 23 and a shoulder 24 formed therein. Within the casing are two oppositely disposed levers 25 pivoted near their central parts in the casing on pivots 26, adjacent to the rod 15. The casing has openings 27 to allow these levers to move into and out of the casing. Upon the lower ends of the levers are integral angled catches 28, positioned to allow them to pass into the groove 23 and engage the shoulder 24. Ad jacent to the upper end of the lever are spring guides 2929 positioned in the casing to retain the lever and its catches in align ment with the rod.

The device is operated as now described. The upper ends of the levers 25 are pushed inwardly, thus causing the catches 28 to move outwardly and release the rod, which has its ratchet or pawl teeth 17 retained in engagement with the teeth 14 of the member 4 by the upward tension of the spring 21. The rod is then pushed downwardly, by applying the fingers to the projections 18, and held until the member 4 is rotated to a desired position, forinstance from longitudinal to transverse position shown by dotted lines in Fig. I. Thereupon the finger grip is released, the spring 21 torces the rod upwardly and the ratchet teeth into renewed engagement with the teeth 14 and the tool in the member is set at any angle between the transverse positions on either side oitits pivot. The wrench jaw 8 is inserted in the socket 6 and retained there by the pin and spring means adjacent, which are arranged to allow of its easy insertion and removal while the member 4 is in any radial position. This tool may be replaced in like manner by various tools having an arm 7 as shown in the wrench jaw and like arm 9 of the hammer 10 in Fig. IV. Thus the device may have a screw driver, lifting claw, etc. It will also be observed that while the teeth are engaged the member 4 can be moved Ill along the ratchet from a longitudinal posi tion in one direction to transverse position and is retained from moving reversely by the ratchet teeth. If desiredto have the member 4 oscillate reversely, the rod is released as described and rotated until the ratchet is reversed.

Its usefulness as awrench ishighly important, as it will be observed that the iwrenchtjaw maysbeset at. any angle and any size of wrench jaw employed. Thus a nut which is in such position .that the usual transverse jaw cannotbe applied to it, and allow movement of the h andle,.can be moved '1 by a wrench jaw inlongitudinal or angled position. It will be observed also that the different sizes of jaws are compact and may 1 be carried about eas1ly,.as well as other indicated tools. The device is distinctly new and useful, as well as economical 1n manufacture, thereby assuring a combination tool holder of moderate expense to the user. The

device-has been reduced to practice and found tobeentirely-practical and operative as described and illustrated I claim 1.
