WRENCH.

Specification of Letters Patent.

Patented Mar. 9, 1920.

Application filed April 19, 1919. Serial No. 291,354.

To all whom it may concern:

Be it known that I, LOUIS BERK, a citizen of the United States, residing at Alstown, in the county of Douglas and State of \Vashington, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.

This invention relates to improvements in wrenches and has for its object to provide a simple but effective socket and angle socket wrench in which the same handle may be used when employing the wrench either as an ordinary socket or as an angle socket.

With the above and other objects in view, I have invented the device illustrated in the accompanying drawings in which- Figure 1 is an elevational view of my complete wrench.

Fig. 2 is a similar view with a part of the casing removed.

Fig. 3 is an elevational view of a socket wrench formed from parts of the wrench of Fig. 1.

Fig. l is a detail view of a. crank handle.

Like reference characters indicate like parts throughout the following specification and in the several views in the drawings in which 1 is an angle wrench which consists of a housing 2 formed of two parts 3 and 4, held together by bolts 5. In the housing is a shaft 6 with its end 7 rotatably mounted in the bearing 8 cast with the housing. The lower end 9 of the shaft projects through. the extension 10 also cast with the housing 2,

1 said extension being bored to form a bearing. The outer extreme end 11 of the shaft is re duced and squared to fit into the end 12 of the hollow shank 13, the lower end 11 of which is enlarged to receive the shank 15 of the socket wrench 16. Fixed on shaft 6 is a bevel gear 17 having an integral collar 18 the lower end of which seats against the wall 19 of the housing whereby the shaft 6 is held in place. The housing 2 has a tubular extension 20 formed at right angles totubular bearing 10, which is expanded to form a hand hold for the tool and which also forms a bearing for the shank 21 on the inner end of which is fixed the bevel gear 22 which is meshed with the gear 17. The outer end 23 of shank 21 is squared to fit either the extension shaft 24 or the square opening 25 of the ratchet wrench 26 which forms the crank for operating shank shaft 21. The square of the extension shaft 21 is also of a size to fit into the opening 25 of the crank 26. The ratchet wrench or crank 26 has a handle 27 whereby the same may be operated. Shank extensions 13 and 24 of various lengths may be provided with the tool to accommodate the same for use in different spaces. \Vashers 2S and 29 are provided for bearing collars l0 and 20 to prevent leakage of grease with which the housing is adapted to be filled.

In Fig. 3 is shown a wrench adapted to be used either as an ordinary socket wrench or as a ratchet wrench and is formed by at taching parts 13 and 26 and 16 of the device shown in Fig. 1, the ratchet wrench opening 25 being ada'pted'to [it on shank 13.

It will be seen from the foregoing description that my wrench combination is an especially useful one and especially for automobilists as the angle wrench is particularly adapted for use in the crank case of the motor in getting at and removing bolts and nuts which are extremely hard to get at and remove with wrenches o-f other types, while the socket and ratchet wrenches are more particularly adapted for removing rim and hub nuts and nuts in places where the shank cannot be rotated by a continuous crank action.

Having now described my invention that which I claim to be new and desire to procure by Letters Patent is:

In awrench of the class described, a casing having bearings at an angle to each other, a driving shaft and a driven shaft mounted respectively in said bearings, means in said casing for rotating one shaft from the other, a. fiat-sided wrench shank detacha-bly connected with said driven shaft, said drivin shaft having a fiat-sided outer end of the same cross-sectional size and shape a said wrench shank. and a handle having a flat-sided opening to receive said outer end of the shaft, or to receive said wrench-shank, when the latter is detached.

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

, LOUIS BERK.
