S Claims. (Cl. 81-55) My invention relates to a remotely operated wrench adapter. In the following description, I will refer to a tool which is useful for adjusting the automatic transmission of an automobile, but it is to be understood that this tool is not limited to that specific use but is capable of manyother uses. I

The ltool of the present invention is designed specifically for adjusting the automatic transmission of a car or other vehicle while it is moving. At the present time, the initial adjustment of an automatic transmission is made before the car is leaving the garage. The car is then driven to determine whether the transmission control linkage should be lengthened or shortened. If it is found that the transmission control linkage needs further adjustment, the mechanic leaves fthe car and makes the necessary adjustments under the..hood on the driver's side. The car is then again driven to determine if any further'adjustment is needed. This adjustment procedure usually must be repeated several times before an accurate adjustment is completed. This procedure is not only dangerous, due to traic conditions, but it is also troublesome and time consuming.

It is the main object of this invention to provide a tool in the form of a wrench adapter which can be controlled from a remote location and which is particularly useful in adjusting the control linkage of anautomatic transmission of a car so that accurate adjustment thereof may be made from within the car while in the drivers seat.

Another object of my invention is to provide a wrench adapter of the type indicated which can be readily mounted in association with the transmission linkage or other mechanism to be adjusted. i

Another object of my invention is to provide a re motely controlled wrench adapter which is of such a nature that the wrench associated therewith will readily follow the nut being adjusted whether it is advanced or retarded.

Various other objects will be apparent.

In the accompanying drawings, I have illustrated the preferred embodiment of my invention. ln these drawings:

With particular reference to the drawings, the tool is shown best in Figures 1 to 4 inclusive, including a casing 10 of tubular form. The forward end of this casing -10 converges into a smaller clamping socket portion 11 which is of substantiallyv U form in cross section being open at one side, as shown in Figure 2. The top wally of this portion 11 receives the clamp bolt 12 which is threaded therethrough. Within the casing 10, an adjusting sleeve 13 is rotatably disposed. This sleeve 13 has a socket 14 of hexagonal or other suitable form in its forward end. The sleeve 13 is disposed between the converging fori. ward end 15 of the casing 10 and a hanged bearing sleeve 16 threaded into the rear end of the casing. The sleeve 16 is provided with a bore which receives an extension 17 at the rear end of the adjusting sleeve 13, the extension being rotatable therein. Threaded on the rearwardly projecting sleeve 16 is a cap 18. y

Removably-ftting in the extension 17 of the adjusting sleeve 13 is the angular inner end of a cable or flexible shaft 19 by means of which the sleeve 13 can` be rotated within the casing 10. This cable 19 is enclosed within a removable flexible tubular sheath or housing 20, the cap 18 cooperating with the ared forward end 21 thereof to anchor it to the bevelled outer endof the sleeve 16 and thereby to the casing 10. A wrench-receiving nut or hand knob 22 is rotatably mounted `on the outer end of the sheath 20 and is non-rotatably anchored to the outer end of the cable 19. Within the adjusting sleeve 13, a compression spring 23 is provided. The rear end of this spring fits in a cup 26 in the sleeve and its forward end fits in a cup 27 in the member 24. Outward movement of the member 24 relative to the sleeve 13 is limited by means of an annular shoulder 25 provided at the inner end otthe hex socket 14, as shown in Figure 1. As previously indicated, this wrench adapter may be used in various ways, but as shown in Figures 7 andS, it is used for adjusting the linkage of an automatic transmission of a car from a remote location, such as the drivers seat. This mechanism may include the accelerator rod 30 which has a lock nut 31 threaded thereon and an adjusting nut 32 threaded on the extreme outer end thereof at opposite ends of a trunnion block 33 which is provided with a trunnion 34 carried by linkage 3S. The object of the adjustment is to thread the nut 32 inwardly or routwardly on the threaded rod 30 to move the rod axially relative to the trunnion block 33 through which the rod 30 slidably passes.

To accomplish this adjustment, the lock nut 31 is first backed off away from the trunnion block 33 on the rod 30, as shown in Figure 5. The end socket portion 11 of the casing 10 is slipped laterally over the nut 432 and then is moved axially inwardly over the nut 32 and over the block 33, as indicated in Figure 5. The U-shape socket portion 11 will engage the block 33 to prevent rotation thereof. The bolt 12 is tightened to clamp the casing 10 to the trunnion block 33, at which time the nut 32 will be within the hex socket 14 formed in the adjusting sleeve 13. The inner end of the rod 30 will contact the friction member 24 and if such end projects inwardly, a suicient amount will move the member away from the shoulder 25 and compress the spring 23, all as shown in Figure 5. If it is found that the rod 30 should be, in effect, shortened by moving the nut 32 inwardly thereon, the knob 22 is turned in a clockwise direction and its motion is transmitted through the cable 19 .to the actual wrench member, which includes the adjusting sleeve 13 and the hex socket 14, thereby turning the nut 32 down on the rod 30 and pulling the rod through the trunnion block 33'. The spring 23" is further compressed by this action and will serve to push the rod 30 outwardly, thereby causing the nut 32 to contact the inner end of'the t'r'unnion block 33' and, consequcntly, locking the nut 32 in adjusted position by this frictional contact. l1 the rod 3'0" needs to be, in effect, lengthe'ne'd, the knob 22 is turned counter-clockwise, causing a similar rotation of the adjusting sleeve 13' and hex socket 14, thereby backing the nut 32' on the rod 30 and permitting the spring 23 to push the rod 30 fiarther out of the casing 10. All' of these adjustments can be made as indicated. in Figure 8 'from the drivers seat, even while the car is moving. When the adjustments are completed as needed, the bottom lock nut 31 is adjusted tightly against the trunnion block 33 and the adapter is removed merely by loosening the bolt 12 and slipping the casing off the trunnion block 33 and the adjusting nut 32 carried by the rod 30.

It will be apparent that my remotely controlled wrench adapter provides a simple and inexpensive device, whereby the adjustment of an automatic transmission may be made safer, quicker, with less effort, and more accurately than by present methods. The device can be easily mounted on and removed from the linkage to be adjusted. My device is so made that whether the adjusting nut is advanced or retarded relative to the threaded rod, the adjusting socket will readily move withv the nut. Also, the plunger structure will keep the adjusting nut in contact with the trunnion sleeve by exerting a push on the rod with which it frictionally contacts.

Various other advantages will be apparent.
