Abstract
A spanner wrench has a Y-shaped body with a pair of rotatable members disposed in the legs of the Y. Each member has a pin carried thereby spaced from the axis. Upon rotation of the members the spacing between the pins is changed to enable them to engage in holes differently spaced from each other.

Upon rotation of the members the spacing between the pins is changed to enable them to engage in holes differently spaced from each other.
7 Claims, 2 Drawing Figures PATENTED HAY 75 INVENTOR. James C. Bares ADJUSTABLE SPANNER WRENCH BACKGROUND OF THE INVENTION 1 Field of Invention The invention relates to so called spanner wrenches, these being wrenches having a pair of projections which may be engaged in spaced apart holes, slots or notches of an article to be turned.
2. Description of Prior Art I-Ieretofore spanner wrenches have comprised a Y shaped body where the stern acts as a handle and two projections are disposed on the branches of the Y a fixed distance apart and extending from the face of the wrench. Obviously the range of articles they could engage was very small. Although adjustable spanner wrenches have been proposed, such as in US. Pat. Nos. 1,882,462 and 2,386,254 they have been very expensive to make, time consuming to use and cumbersome.
SUMMARY OF THE INVENTION The present invention contemplates a Y shaped body made of a pair of identical stampings. The branched ends are offset and provided with apertures to form sockets in which discs are rotatably journalled. The discs carry drive pins which extend from the face of the wrench and may be engaged in holes in the article to be turned. The rotation of the discs causes the spacing between the drive pins, which are differently spaced from the centers of discs, to be varied enabling them to be engaged in holes that are spaced differently apart.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a face view ofa wrench with one of the legs broken away to show the drive disc in elevation.
FIG. 2 is a view taken from the line 2-2 of FIG. 1.
DESCRIPTION OF THE PREFERRED EMBODIMENT As best shown in FIG. 1 the wrench is made from a pair of stampings, generally Y shape, which provide side plates and when assembled, the stems provide a handle and the branches 12, having holes 14 therein providing sockets for holding a pair of rotatable spanner discs 16 which carry drive pins 18.
As can best be seen from FIG. 2, the stems of the side plates lie juxtaposed to each other and may be spot welded to provide the handle. The ends of the Y shaped plates are offset from the handle, as indicated at 10a, to provide a circumferential groove 10b.
The discs 16 have a circular body and a circular peripheral flange 16a extending around the body and are placed between the plates, before welding, with the flanges 16a extending between the surrounding plates. The offset of the plates and the thickness of the flange 16a is such that the discs are easily rotatable in the socket so provided with but slight friction.
The driven pin 18 includes an enlarged head 18a and a stern 18b which is serrated so that it may have a drive fit in a hole in the disc, with the head projecting from one side and the end 18c of the stem projecting from the other side. The holes for the drive pins are disposed off center near one edge of the disc body.
Since the disc may be revolved in the socket, the drive pins are capable of having a variable spacing therebetween depending u on the position to which they are moved by rotating he discs, the greatest spacing being that when the discs are rotated to move the pins to a common diameter of the discs near the outermost edges, 90 from that shown in the drawings. Likewise rotating them so that the pins are in the innermost position provides the lesser spacing.
Inasmuch as the head can be as shown, of one fixed size, and the stem of a smaller size one wrench can be used in slots of the object to be turned where the slots are of different width.
It will be apparent from the above that the discs will be rotated so that the pins will engage in diametrically opposite slots or holes of the object which may be a disc or nut to be moved or held and then used in the manner of an ordinary spanner wrench.
The wrench has a minimum number of parts and the adjustment thereof is quick and easy. Because of its construction the side plates can be made on a single die and the other parts enable an economical device to be made.
What is claimed is:
l. A spanner wrench comprising a handle, a pair of sockets on one end of the handle and means revolvably disposed in said sockets and having article engaging projection extending from at least one side for engagement in recesses in an article to be moved.
2. A wrench as described in claim 1 wherein said revolvable means each comprises a circular body.
3. A wrench as described in claim 2 wherein said article engaging projection each comprises a pin extending through said body offset from the axis thereof.
4. A wrench as described in claim 1 wherein said handle and sockets are formed of a pair'of plates with the socket end offset to provide a space therebetween.
5. A wrench as described in claim 4 wherein said revolvable means comprises acircular body having a peripheral flange extending between said offset ends.
6. A wrench as described in claim 3 wherein each pin has an enlarged head on one side of the body and a smaller stem on the other side of the body.
7. A wrench as described in claim 5 wherein said article engaging means comprises a pin in each body having an enlarged portion on one side and a smaller portion on the other side.
Claims (7)
1. A spanner wrench comprising a handle, a pair of sockets on one end of the handle and means revolvably disposed in said sockets and having article engaging projection extending from at least one side for engagement in recesses in an article to be moved.
2. A wrench as described in claim 1 wherein said revolvable means each comprises a circular body.
3. A wrench as described in claim 2 wherein said article engaging projection each comprises a pin extending through said body offset from the axis thereof.
4. A wrench as described in claim 1 wherein said handle and sockets are formed of a pair of plates with the socket end offset to provide a space therebetween.
5. A wrench as described in claim 4 wherein said revolvable means comprises a circular body having a peripheral flange extending between said offset ends.
6. A wrench as described in claim 3 wherein each pin has an enlarged head on one side of the body and a smaller stem on the other side of the body.
7. A wrench as described in claim 5 wherein said article engaging means comprises a pin in each body having an enlarged portion on one side and a smaller portion on the other side.
