EDWIN 1!. ARNOLD, OF TULSA, OKLAHOMA COMBINATION-WRENCH,

T 0 all whom it may concern.

Be it known that I, EDWIN M.

ARNOL a citizen of the United States,

and resident of Tulsa, in the county of Tulsa and State of Oklahoma, have invented a certain new and useful Improved Combination-Wrench, of which the following is a specification.

The object of my invention is to provide" a wrench of simple, durable and inexpensive construction, adapted to be adjusted to fit any one of a number of different sized nuts such as are used on demountable rims for automobile wheels.

fully set forth, pointed out in my claims,

and illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of my improved wrench.

Fig. 2 is a longitudinal sectional-view of the magazine portion, showing the socket members in position.

Fig. 3 is a transverse sectional view taken on the line 3-3 of Fig. 2; and

Fig. 4 is a detail segmental view, showing one end ofthe magazine portion."

My improved wrench comprises a cylindrical portion 10 having a handle portion 11 which is formed integral with the cylindrical portion, the handle portion 11 having the form of a crank provided with a hand portion 12 and a pivoted plate 13. The

late 13 and the crank portion 11 are sumllir to those used on brace bits and various socket wrenches.

The cylindrical portion 10 is preferably formed hollow and has the section of a hexagon. The inner end of the opening is formed with a cylindrical portion 14, and is screw-threaded. The opposite end oi the opening within the member 10 is provided with an internal annular flange 15. Thls flange 15 i Specification oi fetters Iatent. Patented June 14, 1921. Application filed January 25, 1921. Serial No. 489,854.

rovided with a sh ht ta er so that the p g p outer portion of the flange is provided with a slightly larger opening than theinner cylindrical.

The cylindrical'portion 10 is designed to ortion, said opening being receive a series of socket members l6,each

of which is provided with a socket portion 17 which may have either the form of a hexagon or shape to fit nuts having a corresponding shape. In the drawings I have shown the member 10 of such a length that it is adapt- A further object is toprovide in such a.

ed to receive five 'nf these socket members, each of which is provided with a socket 17 of a difi'erent size from the other, and each of which is provided 18 which is in the shape of a hexagon slightly smaller than the opening within said member 10. 1

- Adjacent to the flange 18 I have'provided a cylindrical portion slightly tapered and of the same diameter and width as the openingwithin the flange 15, the portion 19 being. of a slightly greater diameter than the exterior portion-of the.

socket 17. j

By this arrangement it will be seen that one of the members 16 may be placed with a socket portion 17 through the opening of the'flange 15 in such a manner that the member 19' will engage the flange 15' and will be securely locked in position by a slight downward movement of the member 16. The upper end of the ortion 10 is lar enough so that the mem rs 16 may he slid into oiout of position at the will of the operator.

When the bottom member 16 has been placedin position, the other four members are placed on top of the said member, as illustrated in Fig. position by means of a plug 20 having a screw-threaded portion 21 designed to coact with the. screw-threaded portlon 14. The plug 20 is provided with a star wheel member 22, which is of a diameter greater than each other, and the bottom one of mem- 2, and are then looked in' operator so that the plug may secured in position.

a square or any other desired with a flange portion 19, which is formed,

bers to be rigidly and firmly locked in posi tion in the lower end of the member 10, thus forming a rigid socket member in the end of the member 10, which socket member may be placed upon any desired nut of thesame size as the socket 17 and rotated by operating the hand p rtion 12 in the usual manner. The member 16 will be held against rotation relative to the member 1f. by the hexagonal flange 18 coacting with the inner faces of the member 10.

Thus it will be seen that I have provided a wrench of simple and very cheap construction, which may be adapted to fit nuts of various sizes by placing the proper member 16 in the opening of the flange 15. This change may be easily and quickly accomplished by removing the plug 21, after which the member 10 is inverted, permitting the four socket members inside of the magazine to fall out, and the member in the flange 15 may then be easily removed by a gentle in ward tap on the outer end of said member. This will cause it to be loosened, and it-will then also fall out in the same manner as the others. The proper member may then be selected and placed in the magazine, with its socket end downward, which will immediately and automatically take its place within the flange 15, after which the remainder of the socket members may be placed in position and the cap 20 applied as before described.

By this construction I haveprovided means for storing all of the detachable members where they may be found at the will of the operator. In this connection the device is so constructed that it is necessary that all of the members be placed in position before the active member may be locked, thereby providi against accidental loss of any of the wrenc members.
