Patented Apr. 13, 1920.

Application filed September 23, 1919. Serial No. 325,733.

To all whom it may concern:

Be it known that I, RUDoLr Lnsnxsornnr, a citizen of Jugo-Slavia, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Devices for Holding Bolts of Transmission-Cases, of which the following is a specification.

This invention relates to a multiple socket wrench, and more particularly to a wrench specially adapted for use in connection with automobile transmission gear casings.

One of the main objects of the invention is to provide a wrench capable of being readily applied to the securing bolts of a transmission case so as to hold the same against turning permitting these bolts to be readily removed by one man. Another object is to provide a wrench which is readily connectible so as to be used at either side of the case, selectively. A further object is to provide a wrench of this type which may be readily produced and sold at low cost. Further objects will appear from the detailed description.

In the drawings Figure l is a top plan view of a wrench constructed in accordance with my inven tion.

Fig. 2 is a side view of the same as applied to the left side of a transmission case.

Fig. 3 is a sectional view taken substantially on line 3-3 of Fig. 1.

Fig. 4 is a top plan view of transmission casing with wrench applied to bolts at right hand. side.

This wrench will be described and illus trated as used in connection with the transmission casing of the Ford automobile, though it will be understood that it can be adapted to other similar makes of casings. The crank casing illustrated in Fig. 4: is of substantial ovoidal outline in plan view, tapering from front to rear. This casing A is formed of two sections a and 7) having abutting peripheral flanges c and (Z, respectively, provided with alined openings receiving securing bolts e on the lower ends of which are screwed nuts In practice there are six openings provided at each side of the casing, the first five from the casing recelving bolts 6, and the last opening receiving a machine screw threaded into the lower section of the casing.

In constructing my wrench I bend a piece of steel rod of suitable gage and temper so as to form a suspending frame 1 which conforms substantially in outline to one side of casing A. This frame is provided with a plurality of closed loops 2 which correspond in their relation to each other to the first four bolts 0. At its rearward end, frame 1 is provided with an eye 3 which loosely receives an eye t of a link 5 formed at its free end with a loop 6, the distance between this loop and the last loop 2 corresponding to the distance between the fourth and fifth bolts of the transmission casing. Each of the loops 2 passes loosely through an elongated slot 7 provided through a flattened upper portion 8 of a hexagonal socket 8 adapted to fit snugly over the head of one of the bolts 9. The sockets are thus suspended from the frame so as to be readily adjusted over the heads of the bolts at either side of the trans mission casing.

In using the wrench, the sockets are fitted over the bolt heads at one side of the casing, after which the nuts may be readily removed, as the frame 1 and the sockets cooperate to securely hold any particular bolt against turning. This wrench has been thoroughly tested under actual working conditions and has been found very satisfactory in this respect, it being possible for one man to readily remove the bolts from the crank casing, whereas without a wrench of this type it is necessary to employ two men. By inverting frame 1 the sockets 8 may be caused to easily turn about loops 2 so as to readily adapt the wrench for use at either side of the crank casing, socket 8 carried by link 5 being also readily turned about loop 6 for a similar purpose. t frequently happens that the last or fifth bolt at the left side of the casing is positioned beneath the valve operating mechanism of the motor and a thin wrench has to be employed for gripping this bolt. The provision of link 5 permits the socket 8 to hang down out of the way, in such instances, so as not to interfere in any way with the use of the other four sockets in the manner described.

While I have illustrated and described herein what I have found by practical experience to be the most satisfactory embodiment of my invention it will be evident that slight changes in detail of construction and arrangement of parts may be resorted to without departing from the field and scope of the invention and I intend to include all such variations, as fall within the scope of the appended claims, in this application in which the preferred form only of my invention is disclosed.

Having described my invention, what I claim is:

1. In a device of the character described, a frame corresponding approximately in outline to one side of a transmission case and provided with a plurality of spaced loops, and socket members depending from said loops and loosely connected to the same so as to be readily adjustable about the loops.

2. In a device of the character described, a supporting frame corresponding approximately in outline to one side of a transmission case, a plurality of sockets depending therefrom, a link loosely secured to one end of said frame, and a socket member carried by said link. p r

In testimony whereof I affix my signature.

RUDOLF LIBENSCHEK.
