T 0 all whom it may concern:

Be it known that i, VJILLIAM li irNEn, ncitizen 'th lh'iited Ste .3, 1...:1. citgo, in the county of Cool; and Stste of Illinois, have invented a new and useful irnprovement in Antif' iction CentenBenri QZs for Railway-Cars, of which the li'illowing is s specification.

My invention relelzes anti-friction. center bearings v The object of my invent is to provide an anti-friction center he: iiifor railway ears or other rehioles of e. si nnio, strong, eflicient and durshl construction, in which the wearing tread members of the center plates may he removable and reversible so that when the Wearing faces or treads become worn, they may be reversed, thus doubling or in creasing the life and durability of the center bearing, and so thst the Wearing trend memhors may h- I o ed ror wed when "*orn out Witl. o expense,

their inner ends against the spider hub, and that the spider hub in turn abuts snugly against the hub of the lower center plate. It results from this construction that there is, laterally, no looseness between the parts of the center bearing but that the rollers serve as direct braces between the two center lates to receive the great side thrust of a ieavy car taking a curve at high speed. Also the arrangement. is such that the rollers, while so taking the side thrust, may still act antifrictionally.

I claim i 1. In an anti-friction center bearin for railway cars, the combination with a body bolster, of an upper center plate secured thereto, provided with an annular cone tacedsocket to receive a removable annular tread, a truck bolster, a lower center plate secured thereto, having a cone faced socket to receive a separate piece removable annular tread, upper and lower se arate piece double cone faced reversible annu ar treads fitting in the sockets of the upper and lower center plates, the anti-friction conical rollers interposed between the center plates and their separate piece annular treads, and a roller spacing spider, substantially as s ecified:

2. In an anti-friction center caring for cars, the combination with upper and lower center plates furnished with annular conical sockets to receive removable annular conical treads, of upper and lower separate piece double cone faced reversible annular treads fitting in the sockets of the upper and lower center plates and anti-friction conical rollers interposed between'said treads, substantially as specified.

3. In an anti-friction center bearing for cars, the combination with upper and lower center-plates furnished with annular conical sockets to receive removable annular conical treads,' of upper and lower separate piece double cone faced reversible annular treads fitting in the sockets of the upper and lower center plates and anti-friction conical rollers interposed between said treads, and a piolller spacing spider, substantially as specier.

4. In an anti-friction center bearing for railway cars the combination with body and truck bolsters, of upper and lower center plates, secured thereto and furnished each with an annular cone faced socket, removable and reversible double cone faced treads fitting in said sockets, conical rollers between said rplates and a radial arm s ider having a hub tting a hub on one of saio center plates, substantially as's ecified.

5. In an antiiction' center bearing for railway cars, thecombination with body and truck ,bolst'ers, of upper and lower center plates secured thereto and furnished each with an annular conefaded socket, removable and reversible. double cone faced treads, fitting in said sockets, anti-i'riction conical rollers between said treads, and a roller spacing spider having a hub fitting a hub on one of said center plates and provided with radial arms extending between adjacent rollers, substantially as specified.

6. In an antifriction center bearing, the combination of upper and lower center plates having annular conical treads and telescoping annular hubs and telescoping annular rims, the annular hub of the upper late fit ting within the annular hub of t e lower plate and the annular rim of the lower plate fitting within the annular rim of the upper plate, conical rollers between said lates, and

a roller spacing spider having a hu and provided with radial arms extending between adjacent rollers, said rollers abutting at their outer ends against said outer annular rims of the said upper and lower center plates and abutting at their inner ends against the outer face of the hub of the spider, the inner face of the spider hub abutting snugly against the hub of the lower center plate, so that the said rollers will serve to brace the center plates against side thrust of the car and also act antifrictionally when under such side thrust, substantially as set forth.

'7. In an antifriction center bearing, the combination of upper and lower center plates having ann'ular conical treads, telescoping annular hubs and telescoping annular rims,

the annular hubs of the upper late fitting within the annular hub oi the lower plate and the annular rim .of the lower plate fitting within the annular rim of the upper late, antifriction rollers between the said plates, and a roller spacing spider having a hub fitting and snugly abutting on the hub of the lower center plate and having radial outwardly ta ering spacing arms 'extending between an bearing eripherally against adj a: cent rollers, said rol ers abutting at their outer I ends against said outer annular rims of the 'said upper and lower center plates and abutting at their inner ends against the outer face of the hub of the spider, so that the said rollers will serve to brace the center plates against side thrust of the car and also act antii'rictionally when under such side thrust, substantially as set forth.

8. In an antifric tion center bearing, the combination with upper and lower center plates having telescoplng annular hubs and telescoping annular runs, the annular hub ofthe upper plate fitting within the annular.

hub o the lower plate and the annular rim of the lower plate fitting within the annular rimof the 11 per plate, and antifriction rollers be-' tween the sa1d plates, of a roller spacing spider having radial arms with curved bearing faces to engage the rollers, and provided with a hub, the sa1d rollers abutting at their outer ends against said oute upper and lower center their inner ends agains hub of the spider, 5 hub abutting snugly a lower center plate,s0 th to brace the center plates against side thrust the inner face of the spider r annular rims of the l of the car and also act antifrictionally when I plates and abutting at under such side thrust, substantially as set t the outer face of the forth.
