ROLLER BEARING. APPLICATION mm 1uNe24. 1914.

Appcation tiled June 24. 19M.

To all Iwim/n 'it mag/.concern Be it known that I, Nuouz B. Hasi, subjectl of the ttoman Empire, and residing 1n Paris, Fra nee, have invented certain neu' and useful Improvement-s in Roller-Bearings, of which the follouf'ing is a specification.

'In the different attempts Whichhave been inade o employ roller bearings for heavy loads difficulty has been encountered resulting from lateral shocks due to the force of projection vvhen vehicles moving at a high speed undergo a change of direction. In order to obviate this disadvantage the present invention provides-an arrangement permitting a roller bearing to withstand such lateral shocks -without adversely ade-sting its parallel mmIenient, the lateral shocks according to this arrangement being absorbedby the casing of the bearing itself, the friction upon the end abutment of the'bearing resulting from these shocks being at the saine time considerably reduced.

According to the system constituting the subject matter of the invention a steel ring is arrangedv transversely to the journal and adjacentfto the rollers, this vring being se- Vcured in the roller cage by a bearing sleeve which closes the bearmg casing andis secured by a number of bolts to this casing. A number of thinl steel annular disks independent of one another are arranged between the steel ring above'referred to and other rings transmitting lateral stresses, these annular disks constituting the friction surface of considerable area thereby diminishing the risk of seizing, while at the same time the construction is capable of resisting lateral shocks without in]ury to any parts of the bearing, since the arrangements for rotary movement are quite independent of the arrangementsi'or withstanding end thrust.

The bearing system of the invention above described which is particularly suitable for railway services will be clearly understood from the f'following description relating to the accompanying drawing which illustrates in longitudinal section a form of bearing suitable for axles of railway vehicles, and especially for the driving axles of such vehicles. l

The axle journal A is for a considerable portion of its length surrounded by a bear- -ing sleeve B. a number of rollers C being arranged around this sleeve and carried in a casing l) divided into three parts, the casing Specieation of Letters Patent.

The con-f struction so far described, does notl liovy'evi form part of the present invention;c

AThe axle box E is provided at itsouter end i with an enlargement form-ing an abutment `c for a steel ring F through whichthj'ournal passes freely but which isse'cured'fon its sett formI d by the enlargement c by mans-tif'fa secar ng member G formed integial--vvitlr'a i cap H constituting a cover for-the; axle' box, the can H being secured 'to the aXleboXfF v vith the journal A and the axlebo'x E disks 1d, d?, are capable of sliding rela ne stance as an engagement between then r sulting from a lateral'shock, th pressed against vone :mothers-A At cne'sitle one ot the setsofis'teel disksd. is interposed between the steel ring F and another ring which is freely mounted in, the axle box E and bears against the end of the bearing sleeve B surrounding the jour-4 nal The other set of steel disksdl, is ar ranged on the outer side-of the bearing between the ring lf and the ring J which is freely mounted in the bearing member (x and is supported by a xine-.K mounted upon the extremity of the jourrihlA.

In the event of lateral shocks upon the bearing, one or other of the ringslor J approaches the stationary ring F and either the disks or l are pressed-one against the 95 other according to the direction of the lateral shock experienced by the bearing.

The individual disks of one or other of the o.- or Z which are freely mounted in their respective places in the bearing can, if the stress to which they are subjected is sutilrientiy great. be displaced relative to one an-` other without seizing, the friction surfaces being greatly increased owing to the number ot' the disks, thus having the result of4 preventing any injuryV to the bearing or rotating surfaces dueto seizing. v

The arrangement above described, the function of which is to resist lateral shocks, can evidentlyY be applied to both ends of each bearing in which case disks would provided at eachend of the rollers instead f onlyl at one end as shown in the drawing.

, The lubrification of the bearing is insured by causing the moving parts to he iinm'ersed unoil bath during operation, tlie space M for oil being formed in the axle box Eythe bearingsuriace .of the journal being arranged'.above.the level of the oil` in this spaeeqvhiehis keptfull ofoil. A
