Patented Jan. 5, 1926.



`Application led January To all whom t 11mg/ concern.

Be it known that I, RAY C. CARVER a citizen of the United States of America, residing at Grand Junction, in the county of Mesa and State of Colorado, have invented certain new andl useful Improvements in' vide a wrench of this character in which the wrench jaws may be easily removed and replaced. v

A further object resides in the novel means employed for attaching, without the use of screws, bolts, nuts, etc., the wrench jaws to the wrenchhandle.

A still further object is to so construct a Hat. jawed wrench that it may be readily transformed into a socket wrench.

Other objects and advantages reside in the detail construction of the invention, which result in simplicity, economy, and eficiency, and which will become more apparent from the following description.

In the following detailed description of the invention reference is had to the accompanying drawing which forms a part hereof. Like numerals refer to like parts in all views of the drawing and throughout the description. l

In the drawing:

Fig. 1 is an edge elevation of my improved wrench, partly broken away tol illustrate the interior construction thereof;

Fig. 2 is a face elevation of the same;

Fig. 3 is a detail view of the wrench engag-ing extremity of the handle;

Fig. 4c is a detail view of one form oi wrench jaw which may be used in connection with my improved wrench;

Fig. 5 is 'a detail view 'of the retaining washer employed to secure the wrench jaws to the handle;

Fig. 6 is a detail view of another form of wrench jaw which may be used in conjunction with my'improved handle; and

Fig. 7 is a perspective view of the means employed when it is desired to attach a socket wrench to my improved handle.

The invention comprises a handle 10, out

away at its one extremity to form a wrench seat 11. Concentric'ally projecting from the wrench seat 11 is a wrench post 12, provided near its extremity with an annular roove 13. Slidably mounted within the andle 10 is a pawl 14 actuated by means of a spring 15. Formed on the pawl 14 is knurled linger rest 16.

In conjunction with the handle 10, I employ wrenches such as illustrated in Figs. 4 6 and 7. The wrench in Fig. 4, designated by the numeral 20, is one of the usual type of fiat wrenches. That in Fig. 6, designated by the numeral 21, is one of the usual type of side outlet wrenches. Fig. 7, illustrates, what might be termed, a socket holder 17 carrying a square post 18 for engagement in the square socket of any of the usual ty es of socket wrenches 19. Each of the wrenc es 20 and 21 and the socket holder 17 is provided with an opening 22 designed to t over the post 12 and with peripheral notches 23 designed to be engaged by of the pawl 14. j

The wrenches are held in position on the wrench post 12 by ymeans of a retaining washer 21- carrying a radially extending slot 25. After a wrench has been placed over the wrench post 12, the retainin washer 24 is slid over the wrench, the perip eral groove 13 engaging the edges ofthe slot 25.

lVhen the retaining washer 24 is bein placed on, or removed from, the wrenc post 12, the -slot 25 will occupy the broken line position indicated at 26, Fig. 2. When in this position, the retaining washer may be easily removed in the direction of the axis of the handle 10. The washer is locked in place by giving it a turn so as to move the slot 25 away from the axis of the handle 10 as illustrated in the full line position of Fig. 2.v When the slot 25 is in any other position than that of the broken line position 26, it will be impossible for the retainingl washer 24 to become disengaged since any angular movement will be prevented by curved shoulders27 on the handle 10, bordering the wrench seat 11. By this arrangement, the retaining washer is firmly locked in its position until the operator desires to change wrenches, when it can the extremity y be easily removed without the use of tools.

In Figs. 1 and 2, the wrench 20 is illustrated in alignment with the handle 10. Should it be desired to have the wrench project at an angle from the handle, so as to more conveniently reachthe work, the pawl 14 is operated by means of a linger rest 16 so as to compress the s ring l5 and withdraw the pawl from t e notch` 23. The wrench may now be turned to the desired position, such as one of those illustrated in broken lines, Fig. 2.

The handle 10 may be knurled as illustrated at 28 to give a more eicient hand hold if desired.

While a speciic form of the im rovement has been described and illustrate herein it is desire-d to be understodd that the same may be varied, within the scope o the appended claims, without departing from the spirit of the invention.

Having thus described the invention, what I claim and desire to secure by Letters Patent is i 1. A wrench comprising a handle; a wrench seat formed at one end vof said handle; a wrench post projecting from said seat, said post being provided with an annular groove; a-wrench jaw arranged to be fitted over said post against said seat and means for securing said wrench on said seat, said means comprising a Washer having a radial slot the ed es of which are adapted to enga-ge in sai annular groove in said post.

2. In a wrench comprising a handle, a detachable wrench jaw arranged to rotate on said handle and a pawl arran d to enga.

said jaw to retain it at any esired ang e, the combination of means for securing said Wrench jaw to said handle, said means comprising a pivot post provided with a groove and adapted to pass throu h said wrench ]aw, a washer provided wit a slot adapted to be carried on said post with said slot engaging vsaid groove, and a projection on said handle for preventing the removal of said washer from said post ex-` cept when the former is in a predetermined slot in said pivot post to maintain said.

wrench member thereon; and a curved shoulder at one side of said face acting to allow said washer to be moved longitudinally of said handle and preventing angular movement thereof.

Intestimony whereof, I affix my signature.
