EVERETT \V. BROOKS, OF CHICAGO, ILLINOIS, ASSIGNOR OF TWVO-THIRDS TO JOHN D. ROSS AND WILLIAM S. SHARPNECK, OF SAME PLACE.
ANTlFRICTlON-BEARING.
SPECIFICATION forming part of Letters Patent No. 642,204, dated January 30, 1900.
Application filed December 21, 1898. Serial No. 699,890. (No model.)
To all whom it may concern:
Be it known that l, Evnnnrr W. BnooKs, a citizen of the United States, residing at Chicage, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Antifriction-Bearings, of which the following is a specification, reference being had to the accompanying drawings.
This improvement relates more particularly to that class of antifriction-bearings in which several rollers are connected together by a ring which is carried around in the box by the rollers as they move around; and the invention consists in the peculiar construction, arrangement, and combination of parts hereinafter more particularly described and then definitely claimed at the end hereof.
In the accompanying drawings, Figure l is a vertical central longitudinal section of a shaft and box constructed according to my improvement. Fig. 2 is an end view of the rollers connected together. Fig. 3 is an elevation of a cap on the box detached. Fig. a is a vertical central longitudinal section of one of the rollers. Fig. 5 is a similar section of another form of roller. The last three figures are on a larger scale.
Referring now to the details of the drawings, 1 represents the box, having at one end a cap 9, which is shown on the drawings as screwed into the box, but may be attached in any other convenient manner. In this cap and in the opposite end of the boX is formed a groove 3, in which is set a ball at. In a recess in the center of the cap is forced a block 5 of compressed fiber, which receives the end thrustof an axle or shaft 6, around which is a series of rollers 7, set between two rings 8, connected by pins 9, running through the rollers 7. Each of these rollers is provided with a lining 10 of compressed fiber, bored to receive one of the pins 9, and is provided at each end with a washer 10. These washers may be made separate from the lining, as shown in the right-hand end of Fig. 4, or they may be made integral with the same, as shown in the opposite end of said figure, or the washers may be dispensed with by simply allowing the lining to project at each end, as shown in Fig. 5, but I much prefer the washers whether made separately or integral with the lining.
The grooves 3 are preferably shaped as shown in Fig. 3 and have a portion of the lip notched or cutaway, as shown at 11 in the same figure, so that the ball may be set in the groove or removed therefrom when desired.
\Vith the construction above set forth a box is provided that will run for an indefinite time with little or no oil or other lubricant, for the block of fiber will prevent wear on the end of the axle, the fiberlining willprevent wea on the pins, the washers on the profiil ing ends ofihe linlng will prevent warrttwcemireetus of the rollers and the "rings,'thg jrollersr will" pi'event. J wear t. on the shaft or axle, and the balls will perform the samefu'nction forthe rings, so that the mini mum of wear with the maximum of use results with my invention, which may be used in many different forms and is applicable to railroad-car boxes, line-shafting, the.
What I claim as new is- 1. The combination with a suitable box and axle or shaft, of a series of metallic rollers connected by rings at the ends and having compressed fiberfixedly attached to said rollers"and""projecting from the "ends thereof beyond the metal to reduce the friction on the rings, substantially as described.
2. As an improved article of manufacture, a metallic antifriction-roller provided with a lining of compressed iiber and a faciugmof the Same coivering the ends of the metal body, -siib's tantially as described.
In testimony whereof I affix my signature, in the presence of two Witnesses, this 15th day of December, 1898.
EVERETT W. BROOKS.
