WRENCH Filed Aug. 30. 1929 INVENTOR.
ATTORNEY.
Patented May 19, 1931 UNITED STATES PATET OFFICE EWALD F. PAWSAT, OF MAYSVILLE, KENTUCKY, {SSSIGNOR TO THE WALD MANUFAC- TURING COMPANY, OF MAYSVILLE, KENTUCKY, A CORPORATION OF KENTUCKY WRENCH Application filed August 30, 1929.
My invention relates to the type of wrenches such as are used for removing hub caps from automobiles and other appliances that require a flat type wrench for gripping nuts and the like on a shaft or screw disposed between other parts and inaccessible because of limited space.
It is an object of my invention to provide a socket wrench that is composed of two halves hinged together.
Another object is to provide a socket wrench that can be made of light materials, such as sheet metal or forgings.
A further object is to provide a socket wrench 0f stamping or forging with abutting edges that will prevent the pinching of hands while operating the wrench Broadly it is the object of my invention to provide a hinged socket wrench that will permit the easy application of the wrench to a nut and allow the gripping of the nut without pinching the hands.
These and other objects will be more specifically set forth in the specification and the description of the drawings forming part of this specification.
In the drawings Figure 1 is a perspective view of my wrench.
Figure 2 is an end elevation taken from the handle end of my wrench.
Figure 3 is a section on the line 3-3 of Figure 1.
Figure 4 is a section on the line 44 of Figure 1.
I have shown two halves 1 and 1a which may be made of stamped or forged materials. The ends are the handles of the wrench with the reinforcing sides 3 formed by turning them over during the stamping or forging operation to form channels. This formation of the channel-like structure provides a substantial handle and at the same time provides a space 4 between the handles that makes clearance for any part of the hand coming between the handles while gripping the wrench about a nut.
When both halves are brought together as is shown in Figure 1, they will come in contact along the line 5 which is formed by the Serial No. 389,554.
abutting edges 6 and 6a on the halves. These abutting edges act as stopping means that prevent the handles from coming together and closing the space 4 and therefore eliminate the possibility of pinching the hands during the clamping operation.
The ends 7 opposite the handles are stamped or formed to suit the shape of nut for which it intended. In this case I have illustrated an octagon shape, and it is evident that it may be either square or hexagon.
The ends 8 have offsets 9 bent so as to perniit the joining of the halves by a hinge pin 10 about which the halves rotate. These oil'- sets also allow the surfaces 11 of the halves to be flush across the top and insure the proper contact of the abutting edges.
"hen operating the wrench the halves are separated by pivoting them on their hinge pin and the gripping element is placed about a nut. The halves are then pulled together until they have a firm grip on the nut. At no time during the clamping and operation of the wrench will it be possible to pinch the hand between the handles because the two abutting edges will come together and thereby prevent the handles from coming in contact any more than is shown in Figure 1.
The tool is intended primarily as standard tool equipment to be furnished in the proper size by automobile manufacturers as a hub cap wrench.
Having thus described my invention. what I claim new and desire to secure by Letters Patent, is In a socket wrench, a pair of flat stampings or forgings each forming part of a socket, a meeting portion and one channeled handle portion. means for hinging the same together, and the opposing edges of the han (lle portions being spaced apart by the channeling so that when the socket forming portions are closed against each other, the opposing edges of the handle portions will be spaced from each other, thereby avoiding pinching of the hand of the operator.
EWALD F. PAWSAT.
