The foregoing is the to be applied to the top of a cylinder block to particular construction when the tool is to be I press a replacement sleeve theremto or to remove used to p a Sleeve or bushing into a cylmdera sleeve therefrom, the insertion or removal being 1 1 h the to end of the cynnden The With the sleeve placed manually at the upper end erenee numeral i denotes a cylinder block having of the cylinder t tool is p a d i p siti up n the cylinders 2 provided with the sleeves or bushthe upper end of the Sleeve with the P ings 3.

replace the same with a new one. These opera- Thevdisc and nut are now applied to the lower threaded end of the pull rod from the under side of the cylinder block. The tool is now in position, the wing nuts being loosened so that the frames are adjustable. The jack is now operated and the plunger I3 pressing against the head block 4 will force the lower frame 8, 9, l against the upper end of the sleeve, driving the same into the cylinder. The pressure applied to the top of the sleeve is exerted between the two resistance points, one above and one below the pressure point and both falling within the plane of the sleeve or cylinder and in this there is no lateral pressure or pull upon the cylinder block and breakage of the same is positively prevented. In this instance the lower frame is movable with respect to the cylinder block while the upper frame is stationary. In the event it is desired to replace the jack in use by another while the operation is in progress, the frames may be temporarily locked in adjusted position by tightening the wing nuts. when it is desired to remove a sleeve or bushing from the cylinder block the pull rod I4 is provided with an annular pulling disc I! and nut IS.

The disc I! is formed with a slightly reduced portion it, said disc being of a diameter slightly less than the interior bore of the cylinder so that it is movable therethrough, but of a diameter greater than the bore of the sleeve or bushing i 9 to be removed so that it will not pass therethrough. A cylindrical pedestal 20 of slightly greater diameter than the cylinder bore so that it may be disposed about the mouth of the bore, and of greater length than the sleeve to be removed, is employed. With this pedestal in place upon the cylinder block the tool is placed thereupon, the end plate 9 resting upon the pedestal and the pull rod extending centrally therethrough and through the cylinder and the sleeve therein to be removed. The pulling disc is now applied to the rod, as is also the nut l6, from underneath the cylinder. By operating the jack theupper frame is raised, as denoted in dotted lines in Fig. 2, the disc l1 withdrawing the sleeve from the cylinder and moving it into the pedestal, the lower frame being stationary during this operation. The sleeve being removed rests, during this operation, upon the shoulder formed by the Junction of the reduced portion' I I of the pulling disc and the main body portion of the same.

What is claimed is:--

1. In cylinder sleeve presses, a movable frame, a stationary frame connected thereto, a pedestal receiving said stationary frame, a connection between said movable frame and the sleeve to be extracted, and actuating means for said movable through said pedestal and the sleeve to be extracted, and a pulling disc at one end of said pull rod engaging one end of the sleeve.

4. In cylinder-sleeve presses, an outer frame,

an inner frame connected thereto, a pedestal receiving said inner frame, a connection between said outer frame and the sleeve to be extracted, and actuating means for said outer frame disposed within the confines thereof upon the upper end of said inner frame.

5. In cylinder sleeve presses, a pair of adjustable frames connected together, one of said frames including a base end plate for application to the sleeve under operation, both of said frames being wholly disposed thereby in spaced relation to the upper end of the cylinder, and a pull rod carried by one frame for connection to i the lower end of the cylinder as the sleeve is being inserted.

6. In cylinder sleeve presses, a pair of adjustable frames connected together, one of said frames including a base end plate for direct application to the sleeve under operation, both of said frames being disposed above and in spaced relation to the upper end of the cylinder thereby, a pull rod carried by one frame and extending through the sleeve and cylinder, an anchor disc carried by said pull rod, and a nut carried by said pull rod. a
