1 Claim.

This invention relates to an improved sleeve puller and seeks, among other objects, to provide a device of this character which is more particularly adapted for use in removing broken propeller shafts from splined sleeves, but which may be used in any situation where a push or pull movement is needed for dismantling or assembling parts.

Another object of the invention is to provide a sleeve puller which will effect relative movement of parts, for a separating or assemblingoperation, without damage to the parts.

A further object of the invention is to provide a device of this character which is extremely simple in construction and which may be placed in operation with the utmost facility.

A further object of the invention is to provide a sleeve puller which may be readily adjusted.

Other and incidental objects of the invention not specifically mentioned hereinabove will be disclosed during the course of the following description.

Referring now to the drawing forming a part of my application:

Figure l is a horizontal sectional view of my improved sleeve puller in position in engagement with a splined sleeve and a propeller shaft.

Figure 2 is a vertical sectional View of the device.

Referring now more particularly to the accompanying drawing, wherein the numerals of reference are identical for designating like parts throughout the several views, the numeral I indicates a body which is preferably formed of cast metal and which is preferably cylindrical in shape. The body may, of course, be of any desired shape and is formed with end walls 3 and 4 which are provided with axially disposed relatively large alined openings which are threaded. It should be understood that the threads in the wall 3 are cut in an opposite direction from the threads in the wall 4. That is to say, for example, the opening in the wall 3 would have right hand threads while the opening in the wall 4 would have left hand threads. Formed on the body I medially of its length and at opposite sides, are oppositely projecting bosses 5 and E which are apertured and internally threaded to removably receive handles I and 8 which are adapted to screw into said bosses. The handles are of any desired length but of a length suitable to permit sufficient leverage being exerted on the body so that rotation thereof may be effected. The body is provided with puller sleeves 9 and II] which are adapted to be screwed into the walls 3 and 4 re spectively. The puller sleeves are externally threaded and the threads of the puller sleeve 9 are adapted to match those of the opening 3 while, of course, the threads of the puller sleeve It are adapted to mate with the threads of the opening in the wall 4. It will be understood that by having the threads arranged in the manner described, the rotation of the body will serve either to move the sleeves inwardly or outwardly of the body simultaneously. The sleeves 9 and ID are provided with enlarged reinforcing shoulders I! and I2. Extending radially through the shoulders I I and I2 are set screws I3. The set screws are preferably arranged in an annular series on each of the shoulders and six of the set screws are shown as being embedded in each of said shoulders. It should be understood, however, that any desired number of set screws may be utilized.

As best seen in Figure l, a portion of a splined 20 sleeve I4 is shown extending through the puller sleeve II and a portion of a propeller shaft is shown at I5 and, as shown, is extended through the puller sleeve I2. The set screws I3 are tightened uniformly through the shoulder I I into engagement with the splined sleeve I4 and through the shoulder I2 into engagement with the propeller shaft I5. The puller sleeves will be so arranged that the parts will be self-alining and, therefore, danger of breakage or binding of the parts will be eliminated. As shown in Figure 1, the splined sleeve I4 and propeller shaft I5 are connected with each other. Assuming that it is desired to separate these two parts, it is: only necessary for the operator to rotate the body, by means of the

handles

1 and 8, for shifting the sleeves I I and I2 away from each other and thus shifting the propeller shaft out of engagement with the splined sleeve. If it should be desired to assemble the parts, the procedure is merely reversed. That is to say, the handles I and 8 are swung for rotating the body in the opposite direction and shifting the puller sleeves toward each other.

While the invention is particularly adapted for removing propeller shafts from splined sleeves and performing this operation in such a manner as to eliminate possible injury to either of the parts, it should be understood that my invention may be employed in any place where an assembling or a dismantling operation is to be effected and a push and pull effort is needed.

By the use of my invention a great deal of time may be saved in working on rear axle jobs, as well as other kinds of work, and, furthermore, the in- V ven'tion permits the accomplishment of the work with much greater ease. The sleeves may be readily adjusted in the body for engagement of work of various types.

Having thus described the invention, what I claim is: o

A device of the character described comprising an open ended tubular body having end portions of its walls internally thickened and threaded, externally threaded puller sleeves screwed into said body through opposite ends thereof, one of said puller sleeves having its threads cut in an opposite direction from the threads of the other sleeve whereby said sleeves will be moved in opposite directions when the body is turned, outer ends 7 of said sleeves being externally thickened to provide collars for engaging ends of the body and limiting inward movement of the sleeves, clamping screws threaded through the thickened end portions of said sleeves radially thereof for gripping articlesl passing through bores of the sleeves, bosses projecting radially from. said body midway the length thereof and formed with threaded O sockets, and turning handles having threaded end portions screwed into the sockets of said bosses.
