This invention relates to anti-friction bearings. Y Y
One object of the invention is to provide a simple, practical and efficient anti-friction 5 bearing especially adapted for'railway car side bearings, in which the parts are so arranged that the anti-friction element is automatically returned to normal centered position when free from load.
Another object of the invention is to provide a side bearing including'a base support Yadapted to be applied to the truck bolster of a railway car, which support is adapted to accommodate a vertically adjustable '5 bearing plate upon which an anti-friction element is adapted to move to either side of central position with reference to the support, in conjunction with centering and retaining mea-ns including a housing which W lits over the roller vand the base support in such manner as to enclose 'the same except for the engaging portion of the roller, said housing being movably and detachably connected to said base support and in operative 'f5 position serving to hold the various parts of the bearing in assembled relation, and to release said parts when said housing is del tached from said support.
`@ther and further objects of the invention l will more clearly appear from the vdescription and claims hereinafter following.
In the drawings forming a part of this specification, Fig. l is a vertical sectional View taken through the ends of the body and 21:3 truck holsters of a railway car, showing my invention, in partial veitical section, in connection therewith. Fig. 2 is a top plan view ofthe bearing illustrated in Fig. l, showing the same partly broken'away, and detached u from the truck bolster. And Fig. 3 is a transverse vertical sectional view of the bear-L 4f of the body Abolster and ll the upper side of the corresponding truck bolster of a railway ear. The improved side bearing is shown as applied to the truck bolster and comprises broadly a base support or mounting A; an
.n adjustable bearing plate' assembly B; an
anti-friction element C; and centering and retaining means D.
As shown in the drawings, the base supd port comprises generally box like member plate 2G, walls Serial No. 91,328.
The support is provided with se-y The base support further is provided `with ledges or abutments AZ8-28, extending parallel to the walls 21, one of the abutments being disposed upon the inner side of the end wall 22, and the other abutment ybeing disposed upon the inner side of the end wall 23, the abutments, in conjunction with the side walls-of the housing, providing a seat or chamber for the reception of the adjustable bearing plate assembly B. The side walls 21-21 are each provided with apertures adjacent the end walls 22 and 23, preferably above the abutments 28*28, for the insertion of'retaining bolts as hereinafter vmore particularly de scribed. i
The adjustable plate assembly B comprises the bearing pla-te proper indicated at 29, said bearing plate preferably being of hardened steel and of a form and size so as to lit-between the side wallsr2l2l and the abut-- ments 28-28 as shown in Fig. `1,the meansfor adjusting the vertical height of the bearing plate comprising a plurality of shims 30,
prise ar housing indicated as a wholeat 3l,
resilient means 329-32, and retaining bolts The housing 3llhas side walls 34H34 spaced apart a sufficient distance to fit over the side walls'21--2l of the base support as clearly ,shown in F 3. Each of said side walls h as an inwardly offset centrally disposed extension 35,v theexten sions 35-35 being adapted vto cooperate with the top wall of the' hoiisingm provide a for the rollei a. manner hereinafter more i Hin fully eXplained. The housing 31 also is provided with end walls 236-36, merging with the side walls, the distance between said end walls being greater than the distance between the end walls 22 and 23 of the base support, Each of the end walls 3G is offsetcentrally and outwardly as indicated at 37 to provide spring pockets 3S-38 which when the device is assembled cooperate` with the extensions 24 and 25 of the base support to housethesprings 2Q-32, preferably under a considerable initial. or preliminary compression, at the outer sides of the end walls QQ and 23 of the base support, the springs bearing against the end walls of the pockets and against the outer surfaces of the end walls 22 and 23 of the support. The housing 31 is further provided with a top wall 39, said wall being provided with upwardly curved port-ions 40.-40, one of which is dispnsedl on each side .of the anti-friction element C, the portions 40--40 in conjunction with the extensions 24 and 25 of the side Vwalls defining a cage having an opening 41 through which the anti-friction element projects, The inner surfaces 141 of the portions 4 0-40 are adapted to engage the opposite sides of the anti-friction element so that displacement of the roller to either side of central position causes corresponding travel of the housing 3l. The engaging surfaces 141 are so arranged that when in assembled relation. of the bearing, said surfaces are curved inwardly and disposed above the central axis of the anti-friction element C, said surfaces being straight or vertically arranged as indicated at 42, below the central axis of the'roller, when the same is in position upon the bearing plate 29, so that said surfaces permit different vertical positions ofl the roller resulting from adjustment of the bearing plate, without interfering with the operation of the device. Each of the side walls 35-35 of the housing 31 is provided with horizontally extending longitudinally spaced slots 43. 43, and in order to detachably secure the housing 31 in assembled relation with the base support, the retaining bolts are employed. The bolts at the 'opposite ends of the bearing, `extend through the horizontally disposed slots in the side walls 35 of the housing, and through the annular openings in the side walls 21--21 of the base support, the bolts being retained in detachable relation by means of ordinary nuts as indicated at 44. In order to prevent accidental detachment of the bolts, a locking plate 45 having turned ends 46,-46`is .provided sol as to engage the bolt heads to preven-t'turning thereof, `and on the opposite sideA of the bearing a locking plate 47 similar to the plate 45, is provided, which prevents accidental rotation of the nuts 44, while permitting forcible removal thereof so that the housing 31 may be detached from the base support. With the locking plate arrangement .just described, it will be appreciated that the nuts 44 are held upon the bolts in certain definite positions so that the distance between the bolt heads Voperative condition as illustrated in Fig. 1,
when it is desired to adjust the bearing plate, or replace the springs-or roller, the housing 31 may be removed by loosening the nuts on the bolts and removing the bolts from the bearing, vafter which the housing 31 may be lifted vertically thereby releasing the springs E32-32, and releasing the roller, so that the same maybe removed from the bearing. Then this has been done the bearplate assembly B may be adjusted by substituting, removing or inserting shims 30, as desired. In reassembling the device new springs may be substituted for the springs '32 if necessary, and a new roller mightbe provided if desired, the parts being placed in position before reassembling the device. After the bearing plate has been adjusted, or the springs or-roller replaced if. necessary, the roller is pla-ced upon the bearing tif) plate and the housing partially llitted over the same. The springs are then` interposed between the end walls of the pockets 37-37 and the end walls 22 and 23 of the base member, after which the housing is brought down to rest on the latter. The bolts may then be reinserted to hold the housing in position, which in turn maintains the springs and roller in assembled r lation with reference to the bearing. After the bearing plate is adjusted vertically, it will be appreciated that the roller will be in a new vertical position with respect to the housing 31, and the changes in position-of -the roller are accommodated by reason of the shape of the curved engaging faces 41-41 of the curved `portions 40-40 willbe appreciated.
Then the device is in assembled condition, assuming movement of the anti-friction clement G toward the rightas indicated in dotted lines, the housing 31 will be carried therewith, this movement being permitted by reason of the provision of the slots 43 4?, and during such movement the left hand spring 32 will be compressed between the end wall of the left hand pocket 37, and the wall 22 of the base member, the energy stored in such spring serving to return the housing 31 toward central position, the housing carrying the roller therewith when free from load. Movement of the anti-friction element C toward the left effects a reverse operation of the bearing similar to that just described. i
liy the above described ar1'augement it.
