This invention relates to a cylinder sleeve tool, and refers more particularly to a tool which may be employed either for removing or inserting sleeves in cylinders. It is now a common practice, particularly in the case of automobile engines, to mount removable sleeves or liners in cylinders so that, when worn, they may be re moved and replaced by new ones, thereby savin the labor and expense involved in reboring the cylinders and fitting special oversize pistons and rings.
The invention aims, among other things, to provide a cylinder sleeve tool: for removing or inserting a sleeve in a cylinder and which may be utilized with equal facility for either purpose; which will not in any way damage the cylinder or sleeve during the operation; and which is simple, easy and quick to use, eflicient in operation, and relatively cheap to manufacture.
Another object of the invention is to provide a cylinder sleeve tool including a head having jaws which may be arranged either to engage'the underside of the sleeve for removing the latter from its cylinder, or to engage the underside of the cylinder to hold the head immovable relative to the cylinder during insertion of the sleeve.
A further object of the invention is to provide a cylinder sleeve tool including means for contracting the jaws to disengage them from the cylinder after the sleeve has been inserted in position; thereby eliminating the necessity for reaching beneath the cylinder to do so as the space therebeneath is very restricted when the crank shaft is mounted in position.
Having thus briefly and broadly stated some of the objects and advantages of the invention I will now proceed to describe it in detail with the aid of the accompanying drawings, in which:
Figure 1 illustrates a sectional view of a cylinder in an engine block, and a sleeve in the cylinder partly removed by the tool. I
Figure 2 is an enlarged view showing the tool during the same operation.
Figure 3 is a section on the line 3-3 of Figure 2,

Figure 9 is a section on the line 9-9 of Figure 8, with the release fingers disengaged from the cam slots.
Figure 10 is a sectional view similar to Figure 9 but with the fingers in engagement with the cam slots.
Figure 11 is a reduced size sectional view on the line Il-ll of Figure 10 showing the jaws contracted to permit removal of the tool in an upward direction after insertion of the 'sleeve.
Referring to the drawings, l designates a spindle threaded from one extremity for the greater portion of its length, and terminates in a head 2. The outer end of the latter consists of a circular flange 3 of uniform diameter throughout its width, and extending from the inner side of the flange 3 is an integral portion 4 of decreasing diameter. The larger extremity of this tapered portion is of smaller diameter than the adjacent flange 3 and its smaller extremity adjacent the spindle l is of larger diameter than the latter. Mounted on the spindle I for free axial and rotary movement thereon is a spiderv 5 having a plurality of integral radial pairs of lugs 6 all disposed in a common transverse plane. Pivotally mounted between each pair of lugs 6 is a jaw I supported for rocking movement upon a pin 8 each end of which projects into an aperture 9 formed in one of the lugs 6.
Aligned sets of grooves H] and H are formed across the outer faces of the jaws 7 towards their extremities. [2 denotes a coil spring the ends of which are connected to one another to form a ring. This coil spring ring is placed either around ah the grooves ID or H, so that by rocking the jaws 1 about their pins 8 the adjacent ends of the jaws are moved toward the spindle l and the jaw ends remote from the spring ring are moved outwardly from the said spindle. The inner sides of the jaws 1 adjacent their extremities are provided with heels l3 tapered to correspend with the tapered portion 4 of the head 2; and these inner sides of the jaws at their ends are indented at I 4 to seat against the periphery of the flange 3, for obviously after removing the spider 5 from the spindle I it may be replaced with either end of the jaws adjacent the flange. Between the grooves I 0 and H and the adjacent ends of the jaws 1 the outer sides of the latter are outwardly stepped at l5 and I6 respectively. The steps l5 project farther outward than the steps It. It will also be clearly seen from Figure 2 that the outer faces of the laws I are also preferably so shaped that substantially the lower half of each jaw lies in contact with the bore of the sleeve A when the lower extremity of the la ter is supported upon the steps E6 of the said jaws.
The tool also includes a bushing 29, an annular guide 2| axially slidable in the said bushing over the spindle l; a collar 21. having a thrust ring 23 therein; and a nut 2d, having radially extending handles 2 50., in threaded engagement with the spindle l. The underside of the guide 2! and the ring 23 may be provided with a plurality of concentric annular steps 2 la and 22a to seat upon different sized bushings 2B and cylinders B respectively.
When it is desired to remove a sleeve A from a cylinder B the spider 5 is placed upon the spindle l with the shallow steps IQ of the jaws I towards the bottom (Figure 2). The lower extremity of the tapered portion 4 of the head 2 contacts the heels I3 towards the lower ends of the jaws and forces the lower extremities of the latter outwardly about the pins 3. This movement is also assisted by the spring ring l2 which is then extending around the grooves It. The steps it then project sufliciently outward to extend beneath and engage the underside of the sleeve A. The steps l6 are of such depth that the lower ends of the jaws 1 remain spaced from the walls of the cylinder B. The bushing 20 is then placed upon the cylinder B, over the spindle I, and is retained concentric with the said cylinder by the guide 2|. One of the concentric steps 2 la formed upon the underside of this guide engages the top of the cylinder bore. The nut 24 is screwed down the spindle l onto the top of the collar 22, which has been placed upon the sleeve 2!}; continued rotation of the nut then obviously raises the spindle and its head 2, thereby also lifting the spider 5 and its jaws 1 upon the steps IS on which the lower extremity of the sleeve A is supported.
When it is desired to insert a sleeve A into a cylinder B, the operation, illustrated in Figure '7, is as follows: The spider 5 is arranged upon the spindle I so that the steps l5 of the jaws 5 are towards the bottom, and the spring ring l2 is placed around the grooves H which are towards the top. The spindle and spider are then lowered in the cylinder. As before the tapered portion 4 of the head 2 of the spindle and the spring ring I2 cause outward pivotal movement of the lower portions of the jaws 1 about the pins 9 so that r the steps l5 extend radially outward and engage the underside of the cylinder B. The sleeve A is then placed upon the cylinder B in position to enter the latter, and the collar 22 is placed upon the top of the sleeve. down the spindle against the collar 22. Obviously continued downward movement of the latter, caused by rotation of the nut, forces the sleeve A into the cylinder B. Regarding this collar 22 it will be noted that its underside has a plurality of stepped annular faces an outer one of which is intended to seat upon the top of the bushing 20 while one of the inner ones is intended to seat upon the sleeve A. The provision of extra annular seating faces permits the tool to be employed upon different sized cylinders and for different sized sleeves.
Due to the fact that there is very little space on the underside of a cylinder when the crank shaft (not shown) is in position it is dificult to force the lower ends of the jaws l inwardly, after the spindle I has been lowered somewhat, to permit withdrawal of the tool upwardly through the cylinder. For that reason a releasing member 36 is provided which is freely rotatable upon the The nut 24 is then screwed spindle I, see Figures 7 to 11. This releasin member is provided with a plurality of radial fingers 3| each of which coacts with a cam slot 32 formed across the inner face of one of the jaws I, so that as the member is turned the upper extremities of the jaws are moved outwardly about their pins 8, and the lower extremities of the jaws are moved inwardly sufiiciently to clear the wall of the cylinder A when the tool is removed in an upward direction. As previously stated the nut 24 must first be loosened sufficiently to permit the head 2 of the spindle to drop downward enough to permit this inward movement of the lower ends of the jaws.
While in the foregoing the preferred embodiment of the invention has been described and shown, it is understood that alterations and modifications may be made thereto provided these alterations and modifications fall within the scope of the appended claims.
