Application December 1 0, 1946, Serial No. 715,156

1 Claim. 1 This invention relates to improvements in socket wrenches.

An object of the invention is to provide a-collapsible socket wrench that win tighten nuts on rods or cables that cannot be reached by the conventional type of socket wrench in use at the present time.

Another object of the invention is to provide a wrench that is formed of a few simple parts that is durable in use, efficient in operation and can be manufactured inexpensively for the purpose designed.

With the above and other objects and advantages in view, the invention consists of the novel details of construction, arrangement and combination of parts more fully hereinafter described, claimed and illustrated in the accompanying drawing in which:

Figure 1 is a perspective view of an embodiment of the invention;

Figure 2 is an elevational view partly in section each jaw, but since nuts for varying purposes may have an innumerable number of faces, the jaws may have any number of faces, as desired, to accomplish the required operative use thereof.

Jaw II has a tongue l5 at one end which is received in the bifurcated end 16 of the jaw l2, and the jaws are apertured at I! to receive the pintle pin l8 whereby the jaws are pivotally connected for movement on the pin I 8.

Each jaw, at the end opposite to the pivoted end thereof, is provided with an upstanding vertical projection l9 having flat engaging faces 20, and when these faces are in engaging contact with each other,ethe socket 2| of a handle 22 may be placed thereover to hold the jaws in engagement with a nut 23 for the loosening thereof.

' In Figure 2, wherein there is shown the man ner in which the wrench is used, the numeral 24 designates a bulkhead having a rod 25 passing 2 therethrough, and secured thereto by a nut 26 on one side of the bulkhead and the nut 23 on the other side. The jaws are opened on the pintle l8 and slipped around the nut 23, then with the socket 2! engaging the projection I9, the nut may I be loosened by manipulation of the handle 22.

It is believed that from the foregoing description, the operation and construction of the invention will be apparent to those skilled in the art, and it is to be understood that changes in the minor details of construction, arrangement and combination of parts may be resorted to, rovided they fall within the spirit of the invention and the scope of the appended claim.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:

A wrench comprising a pair of complementary jaws connected for pivotal movement to open or closed position, a pair of upstanding, juxtaposed lugs, each integral with an end portion of one of the jaws, diametrically oppositethe pivotal connection for the jaws and extending in parallel planes at right angles to the plane of the jaws, and a member for cooperation with both lugs, which member is provided with a, socket portion at one end for reception of both lugs in their juxtaposed position, and with an elongated handle in axial alignment with the socket portion, whereby the socket portion, in cooperation with the lugs, holds the jaws in locked engagement with a nut element to be turned, and the handle may be manipulated to operate the wrench.
