NUT-LOCK W'RENCH.
Specification of Letters Patent.
Patented Feb. 19,1918.
Application filed August 16, 1917. Serial No. 186,559.
To all whom it may concern:
Be it known that I, LOUIS M. SARTAIN, a citizen of the United States, residing at Altamont, in the county of Grundy and State of Tennessee, have invented a new and useful N ut-Lock \Vrench, of which the following 18 a specification.
The present invention appertains generally to wrenches, and aims to provide a novel and improved wrench for rotating a pair of members in opposite directions, the wrench being designed particularly for use with the nut lock shown in my Patent #1,217,835, granted February 27, 1917.
It is the object of the invention to provide a wrench of the nature indicated embodying a novel assemblage of the component elements, for carrying out the desired results in an efficient and practical manner, the device being simple in construction and its parts being readily assembled and separated.
With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and 1n the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention can be made within the scope of what is claimed, without departing from the spirit of the invention.
The invention is illustrated in the accompanying drawing, wherein:
Figure 1 is a plan view of the wrench.
Fig. 2 is a section on the line 22 of Fig. 1, showing the wrench applied.
The wrench embodies a yoke or frame 1 having its ends connected by bars 2 providing open sides for the frame, and a palr of circular wrench heads or disks 3 is rotatable within the frame 1, their remote sides hearing against the bars 2 at opposite s1des of the frame. The heads 3 are provided with hexagonal or non-circular openings 1 to engage the members to be rotated, one opening being larger than the other for the movement of the heads onto the members, as seen in Fig, 2. This wrench is intended for use with the nut lock shown in said patent, the larger opening 4. fitting over the nut 5 of over the head 7 of the screw which looks the nut 5 in place.
An outstanding bearing 8, which also serves as a handle, has a reduced end 9 threaded or otherwise secured to one end of the frame 1, and an actuating shaft 10 is journaled through the bearing 8 and has secured to its inner end a bevel pinion 11 meshing with the annular series of beveled or crown teeth 12 with which the adjacent sides of the heads 3 are provided adjacent to their margins. The shaft 10 can be rotated by any suitable means, such as a crank 13 applied to the outer end thereof.
A removable screw or bearing 14 is threadedly or otherwise engaged with the other end of the frame 1 and carries at its inner end a pintle 15 on which an idler bevel pinion 16 is rotatable to mesh with the teeth 12 diametrically opposite to the pinion 11, thereby assuring of the rotation of the heads 3 when the shaft 10 is rotated. The two 'pinions 11 and 16 also hold the heads 3 separated against the bars 2, and when it is desired to remove the heads 3, the screw or hearing 14 is removed from the frame, thereby withdrawing the pinion 16 with it, and this enables the heads 3 to collapse, whereby they can be withdrawn from the frame. The heads 3 can thus be removed for replacement, and heads having difierent sizes of openings 4 can, therefore, be substituted. WVhen the wrench is applied, as seen in Fig. 2, by rotating the shaft 10, the pinion 11 will rotate the heads 3 in opposite directions, therefore, rotating the nut 5 in one direction and the screw 7 in the other direction, and by reversing the rotation of the shaft, the nut 5 can either be tightened or loosened,whichever is desired.
Having thus described the invention, what is claimed as new is 1. A wrench embodying a pair of heads mounted for rotation about the same axis and actuating means for simultaneously rotating them in opposite directions respectively.
2. A wrench embodying a frame, a pair of heads carried by the frame for engaging two members, said heads being mounted for rotation about the same axis, and means carried by the frame operatively connected with said heads for sin'iultaneously rotating them in opposite directions respectively.
3. A wrench embodying a pair of heads for engaging two members and mounted for rotation about the same axis and actuating means having a pinion, said heads having teeth meshing with said pinion for simultaneous rotation in opposite directions respectively.
at. A wrench embodying a frame, a pair of heads for engaging two members carried by the frame and having gear teeth, said heads being mounted for rotation about the same axis, and an actuating shaft carried by the frame having a pinion meshing with said teeth and located between said heads for rotating the heads simultaneously in opposite directions respectively.
5. A wrench embodying a frame, removable heads therein having openings for engaging two members and having gear teeth at their adjacent sides, and a plurality of pinions carried by the frame meshing with said teeth between said heads, one of the pinions being removable to permit the heads to be removed.
In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence'of two witnesses.
LOUIS MARTAIN SARTAIN.
