VJRENCH HANDLE ATTACHMENT,

This invention, stated ingeneral terms, relates to a wrench attachment of the type in which the socket wrench engaging shank may be moved with respect to the handle, whereby the said socket wrench engaging shank may be retained in adjusted position.

The principal object of the present invention may be said to reside in the provision of a simple, efficient, and comparatively inexpensive wrench handle attachment the parts of which are so arranged, constructed, and connected that the socket Wrench engaging shank may be adjustably positioned with respect to the handle throughout the major portion of its extent.

Other and further objects reside in the provision of general details of construction and in thearrangemcnt and combination of parts for attaining the results sought by the leading object.

The invention consists of the novel construction hereinafter described and finally claimed.

The nature, characteristic features and scope of the invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof, and 1n which:

Fig. l, is a view in perspective of a wrench embodying features of the invention. I

Fig. 2, is a fragmentary View in section taken upon the line 2-2 of Fig. 3.

Fig. 3, is a view in cross section. taken upon the line 38 of Fig. 2.

For the purpose of illustrating our invention we have shown in the accompanying drawings one form thereof which is at present preferred by us, since the same has been found in practice to give satisfactory and reliable results, althoughit is to be understood that the various instrumentalities of which our invention consists can be variously arranged and organized and that our invention is not limited to the precise arrangement and organization of the instrumentalities as herein shown and descrbed.

Referring to the drawings in detail, the reference numeral 1 designates an elongated handle, preferably of cylindrical cross section, provided at one end with a holding part 2 and being flat at its opposite end as at 3. Adapted for movement along this cylindrical member or rod 1 is a member 4: which is 1927 Serial No. 188,434.

cylindrical in form, the longest axis of which is dis'posed'at right angles to the longestaxis of the handle 1. Formed integral wlth the member 41 is a socket wrench engaging part 5, which is squared, as clearly shown in the drawings. In orderto'provide for longitudinal adjustment of the member 4 we aperture the member 4 as at 6, the long: est axis of the opening 6 beingarranged at right angles to the longest axis of the handle 1, see Fig. 2. Within this aperture 6 is placed a ball 7 and a spiral spring 8, and we retain the ball and spring within the aperture 6 by means of a pin 9. The ball 7 is maintained in abutting position with the handle 1 by means of the spring 6, as clearly shown in Fig. 3, sothat while the member 4 may be readily moved along the handle 1 it is maintained in frictional engagement with the handle 1. There is thus provided a sliding member 4 with respect to a handle 1, so that different adj ustments may be obtained. This is an advantage where close situations, as they are termed in the trade, can be conveniently handled. other important feature is that the member 1, if desired, may be entirely removed from the handle 1 without dislocating the ball, spring, or pin. This is true because the center line of small hole is tangent to the periphery of large hole.

It will now be apparentthat we have devised a novel and useful construction which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while we have in the present instance shown and.

described the preferred embodiment thereof which has been found in practice to give satisfactory. and reliable results, it is to be understood that the same is susceptible of modification in various particularswithout departing from the spirit or scope of the in combination a rod forming a handle, a one piece member, having a socket wrench formed integral therewith which is of lesser length than said member and slidable along said rod, said member being apertured to form a ball seat, the longitudinal axis of said aperture at right angles to the longitudinal axis of said rod, With the longitudinal medialline of said aperture in a plane above the longitudinal medial line of said rod, a spring pressed ball abutting against said rod tangentially to the upper periphery thereof, and a closure to maintain said spring pressed ball in frictional tangential contact With said rod.

2. In a device of the character stated, a handle rod, a head slidable on said rod and having a bottom socket Wrench, said rod passing transversely through the upper portion of said head, and means for retarding the movement of said head along said rod, comprising a ball positioned in an opening in said head so as to abut tangentially against said rod, a spring positioned behind. said ball for constantly urging the latter inwardly against said rod at a tangent to the periphery thereof, and a closure for the outer end of said opening forming a stop for the outer end of said spring.
