Application filed January 17, 1925. Serial No. 3,063.

The length of the part 13 is suchthat the This invention relates to a speed handle wrench extension and among the objects of a bowed member 2, having a crank handlethe invention are the provision of an article of the character set forth which is simple in'construction and which is quite-effective in action.

In the drawing accompanying and formng part of the present specification, there 1s represented in detail a form of embodiment ber of respects within the scope of the invention defined by the claim succeeding suchdescription.

Referring to-said drawing:

Fig. 1 is an elevation of a wrench extension involving the invention, the view. also illustrating an element of the wrench at the right. i V y Fig. 2 is a sectional elevation of the upper part of the wrench extension with the handle in cross section.

Fig. 3 is a cross section on the line 33 of Fig. 1 looking toward the right.

4 is a longitudinal section.

Like characters refer .to like parts throughout the several views. U

As shown, the wrench extension comprises portion 3 near one end and a shank 4 near the other end, upon which is suitably mount ed for free rotation a head 8, which may be locked thereto in any'suitable manner, as by a spring ring .6 located within complementary grooved portions of the shank and the lower end 7 of the handle. One of the grooves is shown at 5 (Fig. 2). At the lower end of the crank handle portion 3 is a right angled extension 9,'to which is secured a socket 10, the end of which terininates short of aline coincident. with the axis of the shank 4. "The outer end of the socket 10 is provided with an angular opening designed to receive the angular end 13 of a wrench bar 14, which end 13 may be pro- 1 vided with a spring pressed detent 16, to

frictionally hold the bar 14- in the socket.-

tool may be grasped in the hand when rest-' ing on the head 8, the other hand grasping L tent 16, to frictionally secure the wrench T I bar to the wrench head. It will be observed the crank 3, whereupon the wrench bar .14

may be rapidly rotated, to correspondingly By this rot-ate the socket wrench head 15. arrangement thesocket wrench bar 14 may be utilized in connection with the speed handle, or it may be detached therefrom and used as indicated in the right-hand side of Fl 1. The socket 10 is preferably'attached to the 'extension 9 by'means of the pin 11, and the inside of the cavity for receiving the wrench bar extension 13 may .befrecessed, as at 17, forreceiving' the detent 16. It will be observed that when the parts are assembled the main body 14 of thebar is held in substantial alignment the speed handle.

What I claim is:
