Specification of Letters Patent.

latented June 20, 1916.

To all whom it may concern Be it known that we, LEE W. BARBER and EDWIN Vi. WVEBB, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Side Bearings for Cars; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention has for its object to provide an improved side bearing for railway cars; and, to such ends, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the. accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a plan view of the improved side bearing, with some parts broken away and with some parts removed; Fig. 2 is a side elevation thereof with some parts broken away, some parts shown in vertical central section, and with other parts removed; Fig. 3 is a section taken on the line :0 m of Fig. 2; and Fig. i is a section taken on the line r12 a? of Fig. 2.

The numerals 1 and 2 indicate, respectively, the upper section and the lower section of a housing, which is preferably made from castings, but if desired, said upper section may be a pressed steel member. The lower section 1 of the housing has a flanged base adapted to be riveted, bolted or otherwise rigidly secured to the ends of a truck bolster. The body of the lower section 1 is a box-like structure cast integral with the base and suitably ribbed. In the side walls of this box-like structure, is formed sleeve-like seats 3 in which are mounted the ends of a pair of horizontally spaced heavy pins 4. On the intermediate portion of each pin at is loosely journaled a roller 5. The upper surfaces of these rollers 5 are located at the same altitude and extend above the top upper surface of the section 2 of the housing.

The base of the lower section 1 of the housing, just beloweach roller 5, is cut away at 6, so that sand and dirt may work downward out of the housing, it being assumed, of course, that the truck bolster will have some provision, such as a passage to permit the precipitation of the sand and dirt. Horizontal flanges 7 are integrally formed with the sides of the lower section 1 of the housingand extend between the sleeve-like seats 3.

The top of the upper section 2 of the housing is formed with a smooth flat bearing surface 9 and its end portions are bifurcated'to receive the rollers 5 and the prongs thereof are fitted onto the sleeve-like seats o. Flanges 10 are integrally formed on the sides of the upper section 2 of the housing and rest directly upon the flanges 7. Rivets 11 passed through the flanges 7 and 10 rigidly connect the upper and lower sections of the housing. It will be noted that the heads of the rivets 11 are located below the top bearing surface 9. The object of the top bearing surface 9 is to provide a bear ing surface for the roller engaging bearing surface carried by the body bolster of the car, which normally engages the rollers 5, in case said rollers are broken or removed.

The sleeve-like seats 3 hold the pins 4 against lateral displacement, but are open at their ends to permit endwise displacement thereof. To hold the pins 4 against endwise displacement, from the seats 3, depending flanges or lips 12 are integrally formed with the prongs of the upper section 2 of the housing, embrace the seats 3 and overlap the ends of the pins 4:. It is desirable to hold the pins l against rotation, so thatthe rollers 5 will rotate thereupon. To accom plish this result, beveled stop lugs 13 are integrally formed with one of the side walls of the lower section 1 of the housing and extend upward, one into each of the seats 3, formed in the respective side wall, as best shown in Fig. 3. Onev end of each pin l is beveled at lei. These beveled surfaces 14 of the pins 1 engage the beveled stop lugs 12 and hold the pins t against rotation. The stop lugs 13 also prevent endwise displacement of the pins 4, through the seats 3 in which said stop lugs are located.

hat we claim is 1. A side bearing for cars comprising a housing made up of rigidly connected upper and lower members, said lower member having a pair of axially spaced sleeve-like seats extending through the side walls thereof, a pin mounted in said seats and held thereby against lateral displacement but with freedom for endwise displacement, said upper member having flanges overlapping the ends of said pin and holding the same against endwise displacement, and a roller 1 on said pm.

2. Ar'sidebearing for cars comprising a housing made up of rigidly connected Tip-- per and lower members, said lower member havlng a pa r of axially spaced sleeve-like 1-0 seats extending through the side walls thereof, a pin mounted in said seats and held thereby against lateral displacement but with freedom for endwise displacement, said upper member having flanges overlapping the ends of said pin and holding the'sanle against endwise displacement, a roller on said pin, and means for holding said pin against rotation.

3. A side bearing for cars comprising 'a housing made up of rigidly connected up per and lower members, said lower member having a pair of axially spaced sleeve-like seats extending throughthe side walls thereof, a pin mounted in said seats and held thereby against lateral displacement but with freedom for endwise displacement, said upper member having flanges overlapplng the ends of said pm and holdlng the same Copies of this patent 'may be obtained for five cents each,

against endwise displacement, a roller on said pin, and a stop lug extending into one of said seats with which the adjacent end of said pin engages for holding the same against rotation.

4. A side bearingfor cars comprising a housing made up of rigidly connected up-'- the ends of said pin and holding the same against endwise displacement, a roller on said pin, and a beveled stop lug extending into one of said seats with which a beveled surface on the adjacent end of said pin engages for holding said pin against rotation.

In testimony whereof we affix our signa tures in presence of two witnesses.
