WRENCH Filed Ma an 17, 1950 l 9 L! fl In en for A /e x c/e 56/762196/10 Patented Aug. 9, 1932 UNITED STATES ALEX DE SGHBEKO, OF CHICAGO, ILLINOIS WRENCH Application filed larch 17, 1980. Serial No. 436,503.

My inventiton relates to a wrench, and more particularly to an automobile wrench.

Considerable time is wasted by automobile mechanics in finding the proper wrench to fit a particular nut, or in setting an ad ustable wrench to the proper spacing of jaws to grasp a nut.

There are cetrain parts of an automobile which require the most frequent use of a wrench. The spark plugs, for instance, require frequent removal for cleaning and inspection. The drain and filler nuts or plugs which are provided in casings carrying lubricant such as the crank case, transmission case, anddifierential case, probably require most frequent removal for inspection and replenishing of the lubricant. A type of adjustment that is also frequently required on automobiles is the adjustment of the brakes.

In accordance with the general features of the invention I provide a wrench which is adapted for fitting all of the above parts of both the old and new type of Ford automobiles and Ford trucks, and in which the parts are arranged and constructed to provide a convenient and sturdy device.

An object of the invention is to provide a new and improved wrench.

A further object is to provide a single wrench for those parts of an automobile requiring most frequent manipulation.

Other objects and advantages will appear as the description proceeds.

Referring to the drawing:

Fig. 1 is a plan elevation of a wrench embodying my invention, and,

Fig. 2 is a side view thereof.

The wrench comprises a shank or handle 5, having a bend 6, near one end thereof. Secured to the bend is an enlarged portion 7, having a double hexagonal, or serrated aperture 8. This aperture is adapted to fit various portions of a Ford car. It will, for instance, fit the spark plug, for removing and cleaning the spark plugs and replacing them in position. It will also fit the crank case drain nut, and the nut which serves to retain the wheel upon the front axle. straight portion of the shank adjacent to the bend is a stud 9, having a square cross section.

Mounted upon the The base of this stud slopes outwardly as shown at 10, to strengthen the connection between the stud and handle. On account of the position of this stud the enlarged portion 7 is not in the way when using the wrench, and the stud may be used with the same facility as if it were mounted on the end of the handle.

This stud is adapted to fit the differential case drain nut of a Ford automobile.

The opposite end of the shank is provided with an enlarged portion 11, having a hexagonal aperture 12. At the end of the portion 11 is a reduced portion 13, which is narrower than the portion 11, but considerably wider than the handle or shank 5. The portion 13 is provided with a double, rectangular aperture 14 of such size as to fit the front wheel brake wedge adjustment. On account of the confined space in which this adjustment nut is located, the wrench must be in a particular position in order to place the aperture over the adjusting nut. On account of the double rectangular aperture the wrench fits the nut in a large variety of positions, thereby facilitating its use. The end of portion 13 is provided with a square aperture 15, which fits the rear Wheel brake wedge adjustment, and the transmission casing drain and filler nuts.

The relative positions of the apertures is important from the standpoint of the strength of the wrench as well as its use. For instance, if apertures 14 and 15 were placed in the handle preceding the aperture 12, it would considerably weaken the construction of the wrench and at the same time render the adjustments less accessible for these apertures.

A mechanic equipped with this wrench can take care of all of the important adjustments and manipulation of parts which require most frequent attention, thereby saving a large amount of the time which is usually required for finding a wrench to fit these parts, or setting an adjustable wrench.

What I claim is new and desire to protect by Letters Patent of the United States, is:-

A wrench of the character described comprising an integral flat body, the peripheral edge of which continues as a smooth uninterrupted surface and includes an elongated narrow fiat shank having an enlar ed flat head at one end offset from the shank ut substantially the shank y an intermediate diagonal portion, said head having a serrated nut-receivin" opening therein and having an outer circu ar eriphery serving as a handle for the wrenc 1, a square socket operating stud extending from the shank near the diagonal ortion, a second flat head also serving as a iiandle for the wrench and extending from the other end of the shank but in straight alignment therewith with that portion thereof adjacent the shank widening out into a circular portion to provide a better gri for the hand and extending out into an eongated narrowed portion, said latter head having a lurality of varied nut receiving openings in lon itudinal alignment within the limits of the head with a larger one of the openings in the wider circular portion and a smaller opening surrounded by a circular end of the latter said head.

In witness whereof, I hereunto subscribe my name this 28th day of Feb., 1930.
