1 Application filed October 22, 1921'. Serial No. 509,480.
To all whom it may concern.
Be it known that I, JoLrUs KINDERVATER, of the city, county, and State of New York, have invented a certain new and useful Im- 5 provement in Crossheads, of which improvement the following is a specification.
My invention relates to cross heads for ensuring rectilineal movement of the piston rods of locomotive and other motive power engines or of pumps, etc., and is an improvement upon that disclosed in Letters Patent of the United States No. 1,202,866, granted and issued to Charles Markel, under date of October 31, 1916. The object of my invention is to provide, in a cross head of the type referred to, simple and inexpensive means whereby the slippers may be effectively ad justed to take up wear, whenever it may become necessary or desirable to do so, and
necessity for relining the cross head guides be avoided.
The improvement claimed is hereinafter fully set forth.
In the accompanying drawing: Figure 1 2 is a view, partly in side elevation and partly in section, of a locomotive engine cross head embodying my invention; Fig. 2, a vertical.
transverse section through the same, on the line as a; of Fig. 1; Fig. 3, a partial similar 3 section; Fig. 4,.a plan view, on a reduced scale, with the upper slipper removed; and,
Fig. 5, a side view, in elevation and on a similar scale, of a slipper.
My invention is herein exemplified as applied in connection with a locomotive cross head, 1, in which, as in that of Letters Patent No. 1,202,866 aforesaid, the slippers, 2,
are fitted in recesses in the top and bottom of the cross head, which recesses are under- 4,9 cut or dovetailed, that is to say, their side walls are tapered or bevelled towards the sides of the cross head from their outer to their inner ends, as clearly shown in Figs. 2 and 3. The slipper recesses are closed at one end, which is similarly tapered or bevelled, as shown in Fig. 1, and the portions of the slippers. which project outside of the recesses, are machined to fit on longitudinally extending seats on the cross head, on opposite sides of the recesses. The slippers are held rigidly in position by longitudinal bolts, 3, and nuts, 3 and by transverse bolts,
4, and nuts, 4:.
In order to enable adjustment of the slippers to be effected, for the purpose of taking up wear, without necessitating the removal of the slippers from the cross head or relining the guides, in the practice of my invention, I provide side liners, 5, which are fitted in the slipper recesses, between the tapered or bevelled faces thereof and the correspondingly tapered-sides of the slippers, before the transverse bolts, 4:, are inserted, and the nuts tightened thereon. When it is desired to adjust the slippers, to compensate for vertical wear on the cross head the transverse bolts, 4:, are temporarily removed, the side liners, 5, withdrawn, thinner liners substituted in their place, and the slippers moved outwardly until they fit closely against the thinner side liners. Seat liners, 6, are then inserted between the seats on the cross head and the adjacent faces of the slippers, and the transverse bolts, t, are inserted andtheir nuts set up to the proper tight bearing. g
It will be observed that the cost of the liners is practically negligible, and that the adjustments of the slippers which are attainable by their application, may be readily and quickly effected, and do not involve any addition to, or modification of, either the body of the cross head or the slippers.
I am aware that the application of shims or liners, for the purpose of taking up wear of abutting surfaces, in a mechanical. structure, is an expedient which is old in the art, and do not therefore broadly claim the adoption of devices of such character. My invention, however, utilizes them in a novel combination with inclined surfaces on the slippers and cross head, whereby more effective application of means for maintaining said members in fixed relation is provided, than is practicable in prior constructions, so far as my knowledge and information extend.
I claim as my invention and desire to secure by Letters Patent:
1. The combination of a cross head, having undercut or dovetailed slipper recesses on its guide adjoining sides; correspondingly tapered slippers, fitted in said recesses; and means, interposed between the inclined sides of said slippers and recesses, for effecting adjustment of the slippers to take up vertical wear thereof without necessitating their removal fromthe recesses.
2. The combination of a cross head, having undercut or dovetailed slipper recesses on its guide adjoining sides; correspondingly tapered slippers, fitted in said recesses;
10 liners, interposed between the sides of the slippers and the inclined sides of the slip per recesses; and removable seat liners, interposed between the slippers and slipper seats, said members being combined, for
joint operation, to take up vertical wear of 15 the slippers.
