UNITED STATES PATENT OFFICE. THOMAS COOPER, OF KINGSILYNN, IENGLAND. I
ROLLER-BEARING.
Sp'ecification of Letters Patent;
' rimmed March 12, 1907.
I Application filed May 1. 1908. Serial No. 814,616.
- in the county of Norfolk, England, have in:-
vented new and useful-Improvements Relating to Roller-Bearings of which the following is a specification.
The object of the present invention is to.
improve,-with the view to economy, the construction and arranglement of roller-bearm s for railway and ot er heavy vehicles. n
such bearings there is a tendency for the rollers to wear unevenly unless provision is made for assurin their rotation against-4 9, .sufficiently-har surface on apraetically horizontal axis. British Patent July 20, 1901, y incasing the rollers and their cage in a properly-tempered sleeve, which is formed externally with'regard to its inclosing box in" such a manner that there is' a rockin or swiveling action between the two, so tiat the oscillations of the body of the vehicle are neutralized in the bearing and do not reach the rollers in sufficient force to turn or press the latter out of their proper even contact with the axle. The construction of the-sleeve and the case-hardening of the wearing parts to make them sufiiciently durable to}. withstand the stress put upon them cannot be done inexpensively.
My object now is to make a cheaper construction of bearing without the' sacrifice of efficiency,
According to the present invention I eiiect this end as follows: To obtain freedom for oscillation, I interpose between the outside of the axle-box, which sup orts the load, and the spring or other part 0 the vehicle which rests thereon, a 'curved or arched seating formed separate from the box' 'or in one therewith, if preferred. The box itself I make of cast-iron chilled at the crown inside where the'greatest weight is upon the rollers.
In the accompanying drawing I have shown .a construction of roller-bearing -embodying my improvements, Figures 1 and 2 being longitudinal and cross-sections, respectivcly.
This is effected according 'to a ranted tome, No. 14,820,
a-is the axle, preferably ground-steel sleeve bc are the rollers mounted in a cage (1, in
closing the casing forming the .journal and sleeve. g
e 1s the axle-box, made of cast-iron partly chilled internally to give a hardened wearingincased in a hard.
surface for the rollers where the pressure of 'theweight of the vehicle mostly greatly falls.
Th'ehardened portion of the axlerbox 1s indicated by shading in the drawing.
In the socket f 'onthe top of the box e is a plate g, hav1ng an arched u per surface in the irection of the length of t e axle. Located in the socket is a spring-holder, the bottom of which is flat, said bottom resting upon the arched or convex. upper surface of the plate g, th1s spr1ng-holder carrying the vehiclespring t, The construction is such that a rocking movement is ermitted between the bottom of the springolder and the plate 9 laterally, and the oscillations of the vehiclebody are therefore not transmitted to the rollers. The sides of the casting e are recessed at to fit the ordinary horn plates.-
k 1s an oiling-hole provided with a cover, and Z is an oil-outlet near the lower part of the bearing.
m are circumferential oil-channels in the bottom of the casting e. The outer end of the box 6 is closed by a plate n, fixed by bolts and nuts.
ters Patent of the United States, is
A journal-box com rising a casing a portion of which is chille interiorly, a cage pro vided with a series of rollers in the casing, said casing having in its top a socket, a plate having aconvex upper surface in said socket, and a spr1ng-holder having a flat base coacting wit the convex surface of the plate, whereby the oscillations of the vehicle-body are not transmitted to the rollers.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
