1I Claim.

, Thisfrinventionirelates toiai novel andimprovedi side bearingand-.consistsof the'. matters hereinafte'iidescribed andmore particularly pointed out in the appended claim.

The object of the invention is to produce a novel and improved form of side bearing, including a roller casing and filler plate constructed and arranged for use with shims for vertical adjustment of the fill plate, with no-vel means for retaining the iiller plate and shims in position when mounted on a bolster, but permitting ready access to said shims for insertion, removal or replacement, to vary the level of the filler plate.

In the drawings:-

l5 Figure 1 is a view representing a top plan of the improved side bearing;

Figure 2 is a side elevation of the side bearing with parts shown in vertical section as indicated by the line 2 2 of Figure 1; 2O Figure 3 is an end View of the side bearing with parts shown in vertical section;

Figure 4 is a partial perspective view of an end of the casing with the plate and shim retaining member removed and in vertical position above the place which it is to occupy when in position on the end of the casing; and

Figure 5 is a like view but showing said plate and shim retaining member in proper position and secured to the end of the casing. 30 In the drawingsz-IU indicates the casing and II indicates the ller plate, which also constitutes the wear plate. I2 indicates the antifriction roller and I3, I3 indicate shims located below the ller plata-it being understood, of course, that the casing and shims rest directly on the bolster.

The casing III is a hollow shell, open top and bottom, and provided with laterally extending apertured lugs I4 at the base for attachment to 40 the bolster by means of bolts or lag screws,-in a familiar manner. The casing has side walls I5,

I5 and end walls I6, I'I. In the side walls are formed horizontal waysV or vchannels I8, in which travel short studs I 9 on the ends of the roller and 45 co-axial therewith. Said ways or channels extend in each direction from the middle of the casing a distance suicient to provide accommodation for the designed travel of the roller.

The combined wear plate and ller block I I is 50 loose in the casing and is of a familiar form, in

the main having a wear surface 2U inclined in opposite directions from a transverse median line for the purpose of centering the roller and having transverse bottom ribs 2I, one at the middle 55 and one at each end, which present bearings or rests? forthe ller block 'for supporting: engagement' against' the bolster 'orf the shirnsinterposedA between-said'ibolster and `the saidribsz` Horizontal ribs I5a, I5a on the side walls and IGa, I'Ia on the end walls, limit the vertical movement of the 5 ller block in the casing, said ller block loosely tting within the sides and ends of the casing below said ribs, so as to be movable therein for vertical adjustment by insertion or removal of one or more shims between the bottom of said wear 10 plate and the bolster.

On the end wall I'I and projecting therefrom, is a` tting 22, preferably made integral with said casing. 23 indicates a downwardly tapered stud provided throughout the greater part of its length l5 with flat lateral flanges 24, 24 and a top flange 25 extending at right angles to said lateral anges.

The iitting 22 is provided with a way 22a between the proximate surface of the end wall I'I of the casing, as shown in Figure 4. This way is similar in transverse and vertical section to that of the stud, with its lateral flanges 24 so that the stud 23 may be dropped into the way, being arrested in its downward movement by the horizontal top flange 25, which acts as a stop to en- 25 gage the horizontal top end 22h of the fitting 22. When in this position, the bottom end 23a, of the stud projects below the bottom plane of the casing I0, as clearly shown in Figures 2, 3 and 5, to engage with one of the usual holes or openings 26 generally provided in the top plate of the car truck bolster 26a for attachment to side bearings of different designs. For easy access to said hole, said bottom end part 23a of the stud is slightly more tapered than the main body of the stud.

A transverse groove 23b is formed in the stud intermediate its ends. The fitting 22 is formed to provide a cylindrical hole or opening 21 extending horizontally and intersecting the part of the way which receives the stud, so that a bolt 28 inserted through said hole will engage the groove 23h in the stud and act to lock said stud in the tting 22.

The end wall I1 of the casing terminates con- 45 siderably above the plane of the bottom of the casing to leave a transverse opening I'Ib extending the full width of the casing. Into this opening extend the shims I3, as shown in Figure 2, said shims being longer than the wear plate, as shown in Figures 2 and 3. It will be observed that this opening is blocked when the stud 23 is in nal position in the tting 22. When the bearing is rst assembled, ready for attachment to the bolster, one or more shims I3 may be in- 55 serted with thelwear plate II through the openingin the bottom of. the casing. After the casing is bolted to the bolster, further adjustmentv of the vertical position of the Wear plate lll mayV locked in position by ther bolt 28.V

After the bearing has been in use and begins to show wear, it is Va, verysirnple operationy to remove the stud 23 in the Imanner described and insert an additional shim o-r'shims, as required.

The construction described isvery simple'and ecient, is readily capable of economicalmanufacture and easy adjustment' to .rtake'up or provide for wear.
