types wherein the bearing surface is horizontally movable relatively to the base, and

wherein such bearing surface is relatively adjustable to the base, and contemplates the provision of improved means for returning the bearing surface to its proper osition relatively to the base, and improve means for securing vertical adjustment of the bearing surface relatively to the base.

The principal objects of my invention are the provision of an improved side bearing employing yieldingly resistant means for returning the bearing member to its central position relatively to the base, and one wherein the returning means is operative in both directions; the provision of improved means for varying the height of the bearing member relatively to the base, in order to compensate for the wear of the parts in service andfor slight differences in' height met in applying side bearings to cars, and one wherein the means'whereby vertical adjustment is secured will operate to elevate the bearing surface as an entirety and maintain it firmly parallel to itsoriginal plane without any tendency to raise one end of the bearing more than the other, to move the bearing surface laterally With respect to the base 1n which it is mounted,

or to remove anypart of its support whereby a tendency of the bearing surface to tilt relatively to. the base arises, to ether withsuch other objects as may ereinafter .ap ear.

n attaining the foregoin objects, as well advantages as may be below disclosed, I have provided the construction illustrated in the accompanyingdrawings, wherein- Figure 1 is a longitudinal sectional view,

taken on the line I- I of Fig. 2, wherein I have illustrated a preferred form of construction; Fig. 2 is a transverse sectional .view taken on the 'line II--II of Fig. 1:

Fig. 3 is an end view of the structure of cal adjusta Fig. 1; Figs. 1, 5 and 6 are views similar to Figs. 1, 2 and 3 wherein I have illustrated a modified structure embodying my invention, Fi 5 being taken on the line IV-IV of ig. 1; and Fig. 7 is a view similar to Fig. 1 illustrative of yet another modification. Referring first more particularlyto Figs.

land 2, it will be noted that in carry ng out my invention, I employ a base 10 adapted to be rigidly fixed, as by bolts passin through the apertures 11-11, to a true bolster or transom, mounting thereupon a bearing member 12 adapted for contact with a car side bearing. For the purpose of sustaining the bearing member 12, I interpose between such member 12 and the base 10 a supporting member 13 and to secure vertiility between the members 10 and 13, and thus between'the members 10 and 12, I provide the member 13 with a pair of oppositely inclined surfaces as indicated at 14 and 15 and in the intersticial spaces insert oppositely inclined wed e blocks 16 and 17 co-acting with the sur aces -14 and 15. In order to attain simultaneous movement of the blocks 16 and 17 toward the transverse center line of the device with consequent-raising of the bearing surface 12, or like movement thereof away from such center with consequent lowering of the surface 12 relatively to the casing 10,1 make use of a screw 19 having right and left hand threads 20 and 21 engaging the said blocks" 16 and 17 v To the end that the bearing surface 12 may automatically return to its proper position relatively to the base 10, when relieved from pressure incident to its movement from such position as the car rounds a curve, I employ a pair ofsprings 22 and 23 encircling a rod 24'carried in a down ward extension 25 of the member 12 and the ends 26 and 27 of the member 13. The springs 22 and 23 are mounted on sleeves 28 and 29 and on opposite sides of the member 25 which acts as an abutment to retain the springs in position, the surface 30 thereof compressing the spring 22 when the bearing surface 12 moves to theleft of. the position indicated in Fig. ,1, and the surface 31 of such abutment comprising the spring 23 when such surface 12 moves to theright of the position indicated in is will be more clearly seen on reference to Fig. 2 the member 12 is provided with downwardly extending projections whose longitudinal vportions 32 and 33 contact with internal ribs 34 and 35 on the member 13 to prevent undue lateral motion of the surface 12 and whose transverse portions 36 and 37 limitthe longitudinal movement of the surface 12 by abutment against the portions 26 and 27 of such member 13; and that the bearing surfaces 38 and 39 of the member 13, whereby such member is prevented from tilting laterally on its long1-' tudmal axis are provided with angular extensions 40 and 41 terminating in an arched portion 42 over the screw 19, to the end that the member 13 may be stifl'ened and yet fully lowered without contact with the threaded portions 20 and 21 of such screw.

On viewing Fig. 3, it will be observed that for the purpose of providing means for preventing any accidental turning of the screw 19 and thus undesired changein the height of the bearing surface, 1 provide on the outer end of the member 10 a weighted latch 44 pivoted to such member as indicated at 45 and cut away as indicated at 46 to accommodate the head 47 of the screw 19, by means of which construction the position of such screw 19 can only be changed by lifting the latch 44 as by holding the lever 48 depressed until it strikes the surface 49 and then manually operating the. screw 19. When the lever 48 is released. the latch 44 will descend of its own weight and reengage the head 47,- so that, failure to lock the screw in adjusted position is impossible.

Referring now to the modification of my invention illustrated in Figs. 4 to 6, it will be observed that the structure here shown is in some particulars similar to that of Figs. 1 to- 3, but that in lieu of relatively movable members'12'and 13 I make use of a horizontally immobile bearing shoe 12 provided with an adjusting portion 13 having inclined surfaces 14 and 15' where with the blocks 16 and 17 co-act, to secure yertical adjustabilityof the device. It will however, be observed that the device of Figs. 1 to 3 is superior to-that here shown in respect not only of having a movable and a larger bearingsurface, but that by virtue of the peripheral flange 49 of the device of Fig. 1 the entrance of all foreign matter to the interior of the casing is prevented.

In Fig. 7, I- have shown the application of my invention to a side bearing wherein there is employed instead of the ongitudinal moving surface 12 a roller 50 removably mounted in stirrups 51 depending from the upper part 12 of the vertically adjustable block 13", the portions 12 and 42 being cut away as indicated at 52 and 53 to accommodate such roller.

From inspection of Figs. 1, 4 and 7, it will be readily apparent that the members 13-13 and 13 may be readily removed from the casing 10, and that by reason of the enlarged aperture 54 through which the bolt 19 projects, the blocks 16 and 17 with such bolt 19 may readily be removed from or implaced in the said casing 10.

It 18 thought in view of the foregoing specification that no further and more particularized description of my device will be necessary to a full understanding of the operation thereof by those who are skilled in the art to which it pertains.
