TRUCK SIDE BEARING Specification of Letters '.Patent.

Patented May 8, 1906.

.To ttt whom/t may concern:

Be it known that we, CARL E. BAUER and FRANK L. SUSEMIHL, citizens of the United States, residing at Hammond, in the State oiV Indiana, have invented certain new and useful Improvements in Truck Side Bearings, of which the following is a specification,

Our invention relates to trucks for railway cars and thel like, and to the bearings provided between the car holster and the truck near the outside. 'ljhe principal objects are, to provide a superior roller' bearing for such position, to provide convenient means for renewing the bearing plates for such rollers and a convenient design of casing for readily puttin together and taking apart, and to genera ly -improve the structure land o eration of railway truck side bearings. hese objects, and other advantages which will hereinafter appear, we attain hy means of the construction illustrated in preferred form in the accompanying drawings, wherein- Figure 1 is a top plan view of the assembled hearing casing g Figure 2 1s an underplan view of the cover of the casing;

Figure 3 is a plan View of the lower naif of the casing with the bearing rollers removed;

Figures 4 and 5 are horizontal sections taken on the lines (4) and (5) in Figure S;

Figure 6 is a horizontal section similar to that 1n Figure 5, with the bearing rolls in a different position;

Fi ure 7 is a vertical section, taken along the line (7) in Figure 1 y Fi re 8 is a cross section, taken along the line 58u) of Figure 1; and

' Figure 9 is a central vertical section taken along line (9) of Figure 1.

The casing is made in two parts as especially shown in Figures 1, 2 and 3, the lower or base portion 10 being provided with lugs 11 for attachment to the truck bolster and the upper portion 12 having depending flanges 12'a and 12b which engage the ledges l0 on Athe base portion, and also having guide flanges 13 for the accommodation of the body bolster thereon. Each of these arts, referaol made of malleafrle castings, has a caring p ate, 14, 15, of steel which is set in as shown in Figures 7 and 8 A the edges ofthe plete being formed of dove-tail sha e and the `plate secured by bending over t e edges 1 6 and 16a of the casing to hold them in lace. Y Y,

he hearing proper is composed of a series of rolls 17 which run by means of trunnons 18, slipped into the open slots 1S of the traveling frame 1Q, are held in proper relative position to each other and travel along the bearing plates. Near the center of this frame 19 is an o ening 2() in which rides loosely a pin 21 having an openin therethrough as shownin the sections of 1gures 6 and 7, in which are placed two uide bars 22 and 23 having respectively the earing studs 22 and 23a working in o enings 24 in the lower casing 10 and a soc et formed in the upper casing (as shown in Figures 8 and 9) by means of the two extended webs 25 which are formed inte ral with the cover 12. The head 23 is retained therein by means of pin 27 held in the two openings 26.

AThe two bars 22 and 23 slide freely upon each other and also in the opening of pin` 21. The bars su port the pin 21 in the frameV 19, and allow o1P travel of the frame as the rollers traverse the late 15 in either direction, hut cause the rollers to wear over the same distances on both plates, and limit the movement at the extreme positions as shown in Figure 6, by coming in contact with part of the casin i9..

From t ls construction it will be seen that the assemblage ofthe vparts is rendered very easy. The rollers having been put in place on the bearing plate 15, the pin 21 is put in place in the traveling frame 19 and then the bar 22 is thrust through the `opening therein, when the head 22 is placed in its socket 24 and the entire upper shell and the Vtraveling frame 19 is set down over the rolls and other parts, the slots 18 en aging the tru'nnions 18 of the rollers 17 and tgli the lower casing, engaging t e outer ledges 10 on the lower casing 10, as'wiii be understood. The top bar 23 ma now he slid into place and retained therein y the lpin 27 engaging the opening 26. It will be seen that we have designed the form of the casing and of the rollers so as to make a perfect bearing in a circumference about the center of the e flan es 12 slide over ICO truck, and the traveling frame and the roller 17 are free to move the saine distances on the two bearings in either direction until limited by the stop bars 2.2 and 23. Both the bear- `be replaced at bolts to put the bearing together and all the parts are readily removable and renewable. Other advantages will readily occur to those familiar with the art.

Having thus describedr our invention and illustrated its use,wl1at we claim as new, and desire to secure by Letters Patent, is the followin y 1'. il a truck bearing in combination, an upper bearing member provided with upstanding brackets to loosely engage the car bolster, a lower bearing member provided with means for positively securing it to a car member, interlocking means on the two bearing members adapted to permit a sliding 4motion and to prevent a relative vertical movement of such members, and rollers interposed between the members.

2. In combination in a truck bearing, a casing comprising a lower bearing member provided wlth means for fixing it on a truck and an upper bearing member slidingly attached thereto and provided with means for loosel engaging a car bolster, and rollers m- 4close in said casing.

3. In a truck bearing in combination, a casing composed of two slidably attached parts, one part fixed on the truck and one part loosely engaging the car bolster, a set of rollers carried between and engaging said casing parts means for limiting the travel ol the parts of the casing, and means for bolding the parts of the casing together.

4. In combination in a truck bearing, rollers, and an inclosed casing'therefor, said casing composed of two parts slidable on one another and confined together and one of said parts having side brackets to loosely engage and seat the car bolster, whereby the whole bearin may be carried on the truck or bolster and 1s readily removable from the corresponding member.

In testimony whereof we have hereunder sigbned our names in the presence of the two su scribed witnesses.
