vUNITED STATES JOHN PILGER, JR., 0E MIILWA-UkmWISCONSIN,

WRENCH.

Application nl ed September 14, i922. Serial No..588,438.

To all l1071.011?, 'it may cof/wem: Be it known that I, JOHN lPineau, Jr., a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.

My.k invention relates Yto improvements in so called Socket wrenches, an object being to, provide a compact and reliable construction which may be used in places which are ordinarily very inaccessible and which can also-be operated by means of a lever handle in the usual way or by means of gearing.

A further object of my invention is to provide a wrench which will enable inaccessible nuts to be manipulated without difiiculty, which can be easily and quickly adjusted and which is not-liable to break or get out of repair. A further object oi my invention is to provide a wrench that is strong, durable, simple and inexpensive in construction and that is well adapted to the use for which it -is designed.

Other objects and advantagesY of the invention will become apparent during the course of the followin description.

In the` drawing, lw erein like numerals are employed to designate like parts throughout the same,

Figure 1 is a longitudinal section taken through my improved wrench in its assembled condition,

Figure 2 is a section taken on line 2-2 of Figure 1 looking in the direction of the arrow,

Figure 3 is a section .taken on line 3-3 of Figure 1 looking in the direction of the arrow, and

Figure 4e is a detailed construction oi a semi-'circular collar used in accordance with my invention.

In the drawings wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 5 designates an angular housing, which is provided at one end with the internal',

threads 6. A tubular handle casing 7 is adapted tobe connected to one end of the an thread 6, said tubular handle casin 7 being adapted to receive a tubular hand e 8, one end of which is provided with an operating lever 9 and the otherl end ofwhich is provided with a beveled gear 10, which is keyed gular housing 5 by means of the screw to the reduced portion 11 of the handle 8. The handle 8 is provided with an annular groove 12, 'said groove 12 being positioned within the tubular handle casing 7. A semicircular bearing, which is carried by the tubular handle 7 means of a set screw 14 is adapted to ri e in the annular groove 12 in the handle 8. It will thus be seen, that the semi-circular bearing 13, will guard the handle 8 against a latter movement within the tabular casing 7.

As is clearly shown in Fig. 1 oi the drawing, the beveled gear 15 is adapted to mesh with the beveled gear 10. The beveled gear 15 is carried by a socket member '16 which is mounted in the other end of the angular housing 5. The socket member 16 is provided with the annular groove 17 which is adapted to receive a semi-circular bearing 18 similar to the semi-circular bearing 13, and is carried by the angular housing 5 by means of a set screw 18. It will thus be seen that the semi-circular bearing 18 will prevent the pinion 15 Jfrom sli ping out of mesh with the gear 10. It is ound convenient to make the top of the socket member 16 flush with the end of the angular housing 5. The socket member 16 is provided with a recess 20 which is adapted to receive a socket wrench member 21.

In use, this wrench can be operated by I means of the lever handle 8 within the housing- 7, in the usual way or if it is desired it may beused by means of the gearing. It is of course to be understood, that the wrench socket member 21 is interchangeable, or, that is that various sized wrench members may be inserted in the recess 20 within the member 16. The wrench socket member` 21 is adapted to en age a nut 0r the like. The lever 9 may e rotated in either direction, according to whether or not it is desired to screw or unscrew the nut. Therotation of the lever 9 will rotate the handle 8 Within the housing 7, said handle 8v being guarded against lateral movement by means of the. semi-curcular bearings 13 driving in the groove 5. As

the beveled gear 10 is keyed to the reduced end 11 of the handle 8, the beveled gear 15 will be caused to rotate in the same direction, thereby .rotating the wrench socket member 21. It will thus be seen, that I have devised a very simple form of wrench, that may easily be used on the ordinary inaccessible nut, and its value. is enhanced by reason ofthe interchangeable wrench member 21. The number of working parts has been reduced to a minimum, so that the possibility of my improved wrench of becominghtemporarily out of order, is done away wit It is to be understood that the form of my invention herewith shown and described is to be taken as the preferred embodiment of the same, and Various changes in the shape, size and arrangement of lparts may be resorted to, without departing from the preferred embodiment of my invention or the scope of the subjoined claim.

Having thus described my invention, I claim p A wrench of the class described comprising an angular housing, a socket receiving member mounted in one end of said angular housing, a. bevel gear 'carried on the opposite end of' said socket wrench receiving a bevel gear at the inner end of the operating member meshing with the first mentioned bevel gear, a handle casing for receiving said operating member, both of said members provided with annular ooves, a semi-circular bearing receivable 1n each groove, and screws receivable in the housing and casing for holding the semi-circular bearings in place.

In testimony whereof I aiix my signature in presence of two witnesses.
