"WRENCH.

' Specification of Letters Patent.

Patented May as, 1922.

Application filed August 17, 1920. Serial No. 404,076.

. J '0 aZZ cohom it may concern Gofl's, in the county of Nemaha and State of Kansas, have invented new and useful Improvements in Wrenches, of which the following is a specification.

The object of my present invention is the provision of a wrench, designed more particularly for automobile work and possessed of a wide range of utility.

To the attainment of the foregoing the invention consists in the improvements as hereinafter described and definitely claimed.

In the accompanying drawings, hereby made a part hereof Figure 1 is a view showing one use of which my novel wrench may be put.

Figure 2 is a section taken in the plane indicated by the line 22 of Figure 1, looking toward the left.

Figure 3 is a detail section taken at right angles to Figure 2 and in the plane indicated by the line 38 of Figure 1.

Figure 4 is a detail section taken on the line 4-4 of Figure 1. I

Figure 5 comprises disconnected views ofsocket members of different types from those shown in Figure 1 and which may be used interchangeably in the wrench. Any desired number of auxiliary socket members of difierent types may be provided for use interchangeably in the wrench to widen the range of usefulness thereof.

. Figure 6 is a view showing the adaptability of a portion of the wrench to be used as a socket wrench.

Figure 7 is a view like Figure 6 but showing the wrench adapted for use as an efficient. screw driver.

Figures 8 9 and 10 are detail views illustrative of the manner in which the T-head is detachably secured on the end of the shaft comprised in the wrench.

Figure 11 is a detail section on the line 11--11 of Figure 1-.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

Among other elements my novel wrench comprises a frame. The said frame is made up of lapped bars 1 and 2. The-bar 1 is provided at 3 with a transverse aperture, and is also provided at one end with an arm 4 that reaches at right angles therefrom and is provided with a circular aperture 5. The

other bar 2 is longitudinally slotted at 6, is provided at 7 with a loop that loosely recelves the bar 1, and is providedat its opposite end with an angular arm 8 in which is an aperture 9, of angular configuration, Figure 4, said aperture 9 being arranged in alinement with the before mentioned aperture 5. The bars 1 and 2 are adjustably connected through the medium of a headed and threaded bolt 10, and a wing nut 11. Manifestly by virtue of this provision the lapped bars 1 and 2 may be adjustably fixed together to determine the distance between the arms 4 and 9 accordin to the work to be done. In other words t e frame may be increased or diminished in length as desired and then the lapped bars 1 and 2 may be adjustably fixed with respect to each other. It will also be noted in this connection that the lapped bars reinforced and lend increased strength each' to the other with the result that a strong and durable frameis produced.

In addition to the frame referred to, the wrench comprises a shaft 12, of circular form in cross section, the

ends

13 and 14 of which are of angular form in cross section. On the inner angular end 13 of the shaft 12 is removably arranged an interiorly angular portion of a socket member 15, and in the angular aperture 9 is arranged the exteriorly angular portion of a socket member 16, Figures 4 and 11. At their inner .opposed portions the said socket members are interiorly angular in order to engage the head of a bolt and a nut on. the bolt, respectively, after the manner shown in Figure 1. Being removable the socket members 15 and 16 are adapted to give place to socket members of different sizes and shapes of which any desired number may be furnished in a kit.

Surrounding the shaft 12 and interposed between the abutment furnishedby the enlargement of the end 13 and a washer 17 on the shaft at the inner side of the arm 4 is a coiled sprin 18, the function of which is to yieldingly thrust the shaft 12 toward the arm 8 of the bar 2.

The manner of using the wrench as thus far described will be readily understood by reference to Figure 1, and need not therefore be enlarged upon. I

The shaft 12 is equipped with a removable T-handle 19, said handle having an angular aperture 20 to receive the angular end 14: of

the shaft. It will also be noticed in this connection that in one side the said angular end 14: has a socket 21, and that the handle 19 is provided with a pin 22 adapted to enter the said socket 21 and thereby removably fasten the handle 011 the shaft. The pin is mov able through the aperture in one wall of the angular aperture 20 and is connected adj acent to its outer end to an intermediate point in a spring rod 23. Preferably the saidrod 23 is extended through a. diametrical aperture in the outer end of the pin 22, Figures 8,

9 and 10, and said spring rod 28 is arranged in a groove 24: in oneedge of the handle-l9 and ,is fixedly connected at one end of the said handle 19 as indicated'by 25. The opposite end of the spring rod 28 is provided vith an arm 26. This arm extends loosely througha'bore 27 in the handle 19 and is de signed to rest at its free end in a recess 28 formed in the edge of the handle opposite to theedge at which the rod 2-3 is disposed. Manifestly by pressing with a thumb on the free end of the arm 26 the operator is enabled to move the pin 22 outof the socket 21 in the handle end let, whereupon the handle 19 may be slipped off the end ll of the shaft 12. It also follows that the'handle 19 may be ex peditiously applied to and detachably fastened on the end le of the shaft 12. In Figure 6 I illustrate the manner in which the shaft 12, the T-handle 19 and one of the socket members 15 or16 may be usedto form a socket wrench, andin Figure 7 I show that the said elements plus a .screw engaging member 30 my be used to form an efficient screw driver. i

The angular end 13 of the shaft 12, and

the angular aperture 9 in the angular arm 8 are so constructed that any standard socket member canbe used in connection with the improved wrench.

It will be apparent from the foregoing that my novel wrench is especially adapted for removing the bolts from automobile housings and differential casings, inasmuch as the wrench enables a single workman to do the work without the help of an assistant or assistants.

Having described my invention, what I claim and desire to secure by Letters-Patent, 1s

1. A wrench comprising a frame made up of lapped bars one of which is provided with other of which is an angular aperture alined with the clrcular aperture, a headed and.

threaded boltextending through the slot and aperture of the lapped bars, and a nut mounted on said bolt; a shaft of circular form in cross section arranged in the circular aperture of one arm of the frame and having an eXteriorly-angular inner end, a spring surrounding the shaft and interposed between said cXteriorly-angular end thereof and one of the frame arms, a handle detachably fastened on the outer end of the shaft, and socket members, one removably arranged in the-angular aperture of the frame and the other removably arranged on the eXteriorly-angular end of the shaft, said wrench capable of disassembly for convenient carriage in a tool box; I

2. The combination with a shaft havingan angular end and a socket in one sideof said end; a handle having an angular aperture receivingthe angular end of the shaft and also having a longitudinal groove in one of its edges and a bore extending from one end of said groove to the opposite edge of the handle and further having in said opposite edge and in communicationwith the bore'a recess, a pin movablethrough an aperture in one wall of the angular aperture in the handle and adapted toenter the socket in the shaft, and a spring rod connected at one end to the handle in the groove thereof and.

extending through an aperture in the pin andhavlng at its free end an arm extendlng through the bore in the handle to the recess in the opposite edge of the handle.

In testimony whereof I affix my signature.
