UNITED `STATES PATENT OFFICE.
FRED E. COOPER, OF LOS ANGELES, CALIFORNIA.
LINER' FOR PUMPS AND THE LIKE.
Application mea November 24, 1922. serial No.. 603,001.
To all whom- 't 01mg/ concern Be 1t known that l. FRED E. COOPER, a citizen ot the United States, residing at Los Angeles, 111 the county of Los Angeles and State ot Califorma, have invented new and useful improvements 1n Liners for'lumps and the like, of which the following is a specification.
This invention relates to pumps and more particularly to ,reciprocating slush pumps. Reciprocating pumps which are utilized for pumping ofslush including a large percentage of gritty material become inefficientV because of the rapid wearing of thelining. It has previously been pro-posed and practiced to provide removable metal liners, but this is an expensive practice due to the cost ot the metal liners.
It is a broad object of the present invention to provide a removable pump cylinder bushing of low Vprice material having a metal liningV or barrel for actually taking the wear; the lining being m-ade of comparatively thin metal and being supported by its shell or bushing, the latter being adapted to be readily inserted in the cl1a.m-
' ber of the engine cylinder.
Other objects and advantages will be made manifest in the following specication of an embodiment of the invention illustrated in the accompanying drawings, wherein- Figure 1 is a side elevation and central longitudinal section of a portion of a reciprocating pump. -v
Fig. 2 is a central longitudinal section lof the renewable cylinder bushing.
Fig. 3, is an end view of the bushing.
The pump bushing and liner of my invention consists of an exteriortubular jacket -or shell 2 of suitable length and diameter or diameters to fit within the bore 3 of a pump cylinder 4. In the present embodimentof the invention the bore 3 is shown of diiierential diameters having a larger forward bore portion 3', access to which is readily had by removing a pumphead 5. The outer end of the cylinder 4 is provided with an annular clearalice pocket or recess 3. l
The removable and renewable lining shell 2 l prefer, for purposes of economy, to construct of cementitious material, and this cement shell or jacket is provided with a suitable metallic wear taking liner 10 which obviously, since it is externally supported by the jacket 2, may be of comparatively thin sheet or other metal so that as soon as it has been unduly worn the jacketv with. its lining can be readily removed with but low cost of waste.
VThe exterior of the shell or jacket Q is made approximately complement-ary to the differential bore of the pump cylinder, and as shown, the jacket has a cylindrical portion 2 to tit the bore 3 and has a front end shoulder 2 to fit the bore 3. The latte-1' is of such length that suitable packing material 7 may be compressed between the shell and the bore of the cylinder. vThe outer@ most end of the jacket is provided with a flange 2b adapted to be disposed in the recess 3a of the bore when the jacket is driven home.
From the above it will be seen that I provide a renewable and removable pump linor shell which is provided with a wear takinv' metallic lining.
urther embodiments, modifications and changes may' be resorted to within the spirit of the invention as here claimed.
What is claimed is:
1. A renewable and removable pump bushing consisting of a. cement jacket having dierential external diameters adapted to. conform to the bore of the pump cylinder having differential internal diameters, said jacketl having a metallic wear taking-liner.
2. In combination with a pump having a cylinder with differential bores, a cement jacket having diameters complementary to the bores and providing a packing space between the, cy1inder and the jacket, packing arranged in said space, and a metallic 1ining in the jacket. f
In testimony whereof I have signed my name to this specicatlon. l
FRED E. COOPER.
