EXTENSIBLE WRENCH SET WITH MAGNETIZED HEADS Filed May 31, 1955 23 22 z5 l Li /6 23 t 24 y; m
INVENTOR ATTORNEY5 United States Patent EXTENSTBLE WRENCH SET WITH MAGNE'I'IZED HEAD'S Billy J. Jenkins, Birmingham, Ala.
Application May 31, 1955, Serial No. 512,202
1 Claim. (Cl. 81-71) The present invention relates to wrenches, and more particularly to wrenches of the internal or Allen type provided with means to extend the length of the wrench.
The primaiy object of the invention is to provide an Allen wrench with a head for receiving the shank of the next larger wrench size.
Another object of the invention is to provide a wrench of the class described in which the head is formed with a polygonal outer surface to permit the turning of the wrench by means of other wrenches.
A further object of the invention is to provide a wrench of the class described in which magnetic means are used to maintain the wrenches in engagement with each other while in use.
Other objects and advantages will become apparent from the following specification when read in light of the attached drawings, in which:
Figure 1 is a top plan view of the invention.
Figure 2 is a side elevation of the invention, shown partly in section for purposes of clarity.
Figure 3 is a transverse cross-section taken on line 33 of Figure 2, looking in the direction of the arrows.
Figure 4 is a transverse cross-section taken on line 4-4 of Figure 2, looking in the direction of the arrows.
Figure 5 is a perspective view of one of the wrench elements.
Now referring to the drawings in detail, wherein like reference'numerals indicate like parts throughout the several figures, the reference numeral indicates, generally, an Allen wrench having a polygonal shank 11. An enlarged head 12 is formed on one end of the shank 11 and has a polygonal outer surface 13. A socket 14 having a polygonal inner surface 15 is formed in the head 12 and is adapted to fit the shank (not shown) of the next larger wrench (not shown).
A second polygonal wrench shank 16 has a head 17 positioned on one end of the shank 16 and it likewise is formed with an outer polygonal surface 18. A socket 19 is formed in the head 17 with an inner polygonal surface 20. The socket 19 is adapted to receive the shank 11 of the wrench 10.
A polygonal shank 21 is formed with a head 22 on one end thereof with the outer surface of the head 22 having a polygonal surface 23. A socket 24 extends into the head 22 and has an internal polygonal surface 25 formed therein. The socket 24 is adapted to receive the polygonal shank 16 therein.
Each of the heads 12, 17 and 22 is magnetized, so that the shanks ll, 16 and 21 will be magnetically held in the heads after they are inserted in the socket.
In the use and operation of the invention, when an Allen head screw must be turned and the screw is remote from the closest point accessible with the normal tools, the wrenches forming the portions of the kit making up applicants invention are assembled by inserting the shank 11 into the head 17 and the shank 16 into the head 22 to form an Allen wrench having a length substantially greater than normal. Obviously, the Wrenches can be extended in length as far as necessary to accomplish the desired task. The outer polygonal surfaces 13, 18 and 23 provide a means whereby end wrenches, pliers, socket wrenches or box wrenches may be used to turn the Allen wrench after it has been seated in the head of the Allen screw. It should be understood, of course, that various extensions could be made following the teachings of this invention wherein the sockets contained within the heads would be the same size as the shanks, to permit extending the wrenchs effective length without decreasing the size of the available Allen wrench end.
Having thus described a preferred embodiment of the invention, it should be understood that various modifications and structural adaptations may be resorted to without departing from the scope of the appended claim.
What is claimed is:
A wrench of the type having a plurality of diiferent size members each having a polygonal shaft and a head, and each head being integrally connected to one end of a shaft, and having a polygonal outer surface, each head being provided with a polygonal internal socket extending into said head from the side opposite its shaft, each head being magnetized to hold said wrench in engagement with a metallic body, said members being arranged in end to end relation with each shaft being receivable in the magnetized head of the next smaller member and maintained therein by the magnetic attraction of said head.
