Like characters offrefer'ence `are used throughout the following -specication and the i' accomslidably extends. through the Vvertical bore I I2 in the head member 5an`d neck l I.

The piston rod 2|J'isof sufcientlengtnto extend through the engine cylinder 2`ar1d through. the metal sleeve or liningZI before it is inserted within the engine cylinder 2. The `lower endol"1 the piston rod* 2ll"is'threaded,` as at 22 and isf.' adapted to receivea securing nut` 23 threadable"` thereon.

The metal sleeve orflin'mg 2I isformed about its'upper end with a'laterally extending peripheral positioning flange A2lil which willseat against1 thelower surfaceof `the head memberfiwhen` in position for insertion within the engine cylinder 2, said iiange--Zll being adapted to be receivedl within the annular peripheral groove or seat 255" formed in the enginefblock rI about the upperA end of the cylincler'Z.`

Very often a metalsleeve Aor `lining `2 I is somewhat longer than the length Vof the engine cylinder 2 into which` it is to be inserted, and will` extendbelow the same. when` inserted within the cylinder.

To provide for these variations in the lengths panyingV drawings to4 designateJ corresponding 554,01 the metalsleeves'or inserts 2I, there ispro'- parts;

of metal or any other suitable material, having a cylindrical seat or recess 21 formed in its upper surface of a similar diameter to the diameter of the engine cylinder 2. A peripheral upstanding supporting ange 28 is formed about the seat of the adapter body 2G with the opening of the cylinder 2 and said recess 21 being in vertical and axial alignment. A centrally disposed vertical bore 29 is formed through the cylindrical adapter body 26 to permit the piston rod 26 to slide freely therethrough as the sleeve or lining 2| is being inserted within the engine cylinder 2. Three equally spaced, circumferentially disposed, threaded bores 36, 3| and 32 are formed through the adapter body 26 in circumferential arrangement being disposed between wells or seats 33, 34 and 35, adapted to receive the three coil springs 36, 31 and 38.

A guide disk 3S is provided with a central vertical bore 4 6 through which the piston rod 26 will pass, andA with three circumferentially disposed bores 4 I, 42 and 43 extending through the disk for receiving the three guide pins 44, 45 and 46 which are headed, as at 41, and are screw-threaded, as at 48, on their lower extremities for threading through the threaded bores 36, 3| and 32 in the adapter body 26.

It will therefore -be seen from Figure 2 of the drawings that the coil springs 36, 31 and 38 which are seated in the wells `33, 34 and 35 will support the disk 39 partially within the cylindrical seat or recess 21 formed in the upper surface of the adapter body 26 and partially within the hollow cylinder or wall 2, while the three guide pins 44, 45 and 46 will guide the vertical movement or adjustment of said guide disk 39. The guide pins 44, 45 and 46 being externally threaded through the threaded bores 4|, 42 and 43 through the adapter body 26 will permit of adjustment of the guide disk 39 with respect to said cup-shaped body 26.

From the foregoing description, the mode of operation will be as follows: The hydraulic power cylinder 4.with its piston supporting piston rod extending through the head 5 and neck with the packing gland 49 threaded about the lower end of said neck is placed in position for the sleeve or lining 2| to be telescoped over the lower end of the piston rod 26 to seat on the head 5, and the piston rod will be inserted downwardly through the cylinder V2 inthe engine block I, as clearly illustrated in Figure 2 of the drawings. With the piston I3 near the bottom of the hydraulic power cylinder 4, the lower end of the piston rod 20 will extend considerably below the lower end of the engine cylinder 2, and the guide disk 39 and cylindrical adapter body 26 will be telescoped over the lower end of the piston rod with the upstanding flange 28 in contact with the lowersurface of the block I, being secured against aV piston rod carried abutment means, herein shown as the nut 23. In this position, the guide disk will be resiliently held in elevated position partially within the recess 21 in the adapter body 26 and partially within the cylinder 2. Hydraulic nuid under pressure will be admitted through the connection 9 to the interior of the hydraulic power cylinder 4 below the piston I3 and the piston will be stationary, since the piston rod 26 is rmly anchored at its lower end beneath the bottom of the engine block I. Therefore, as the iiuid under pressure is admitted below the piston within the cylinder 4, the cylinder will be forced downwardly, thereby causing the head 5 thereof to force the sleeve or lining 2| downwardly within the engine cylinder 2 until the annular peripheral flange 24 on said sleeve is received within the annular peripheral seat 25 formed in the engine block I about the upper end of the cylinder 2. As the sleeve or lining 2| descends, and should the same be longer than the cylinder 2, its lower end will engage the guide disk 39 and force the same downwardly against the tension of the three-coil spring 38, thereby guiding and supporting the lower end of said sleeve or lining 2| until it is firmly and xedly positioned within the cylinder 2. Y

From the foregoing description, it will be apparent that there has been devised and provided a highly eflicient form of sleeve inserter adapter which will be relatively inexpensive to manufacture and produce.

While the preferred embodiment of the instant invention has been illustrated and described, it will be understood that it is not intended to limit the scope of the invention thereto, as many minor changes in detail of construction may be resorted to without departure from the spirit of the invention.
