- v ments in Bearings, of which the following 1s a'full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same. v
TlllS invention relates to bearings, and
f more articularly to anti-friction metal bearings or the axles of railway cars, tram cars,
or similar vehicles.
' I One of the objects of the present invention isto prolong the life of the bearing, thereby enabling a greater mileage to be obtained i than has been possible in similar bearings as hitherto constructed.
.Another object thereof is to provide a construetion such that the bearing of anti-friction metal is more firmly secured within its casing or shell than is the case in bearings of this character now in use.
Other objects will be in part obvious and in, part pointed out hereinafter.
1The' invention accordingly consists in the features ofconstruction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the followin c mn theaccompanying drawing, wherein is illustrated one of the various possible embodiments of my invention, Figure 1 is a- View in perspective showing the same. Fig.
2 1s aview in crosssection taken on line c-a. of Fig. l.
Similar reference characters refer to similar parts in both views of the drawings. Referring now to the drawings, 1 represents the outer shell or casing of the bearing a Y. which may be constructed of any suitable material, such as, for instance, malleable iron, steel or brass. This casing is provided upon its inner surface and in the crown portion thereof with one or more longitudinally extending rooves 2, which are preferably of dove-tail shape as clearly shown in the drawing. Casing 1 isalso provided with one or more elongated apertures 3 in each of its side portions, as shown, the exterior sides of depressions as at 4, through the bottom walls of which apertures 3 extend.
The lining of the shell is constituted by a plurality of tenons (3 and 7 which fit- Within the dove-tail recesses of the casing. These tenons serve to firmly secure the body of antifriction metal within the casing.
In order to prolong the life of the bearing and increase the mileage of the anti-friction metal, the arch of the shell is constructed to have a different radius from that of the axle upon which the bearing is to be used, so that the anti-friction metal will have a considerably greater thickness in the crown of the arch of the shell where the weight of the load is borne, than at its sides. In the present instance the construction is such that the thickness of the anti-friction metal is more than doubled in the crown portion of the arch of the casing, such construction thereby effecting'a corresponding increase of the life of the bearing and the mileage which may be obtained therefrom.
The antifriction metal is mounted within the shell of the bearing by pouring the same in liquid state thereinto so as to fill the dovetail longitudinal grooves in the crown and side portions of said shell, which, in the present instance, has shoulders as at 8 in its lower portion, against which seat the lower side portions of the anti-friction metal.
It will accordingly be seen. that I have provided a construction well adapted to at tain, among others, all the ends and objects above enumerated ina simple and efficient manner. Heretofore it has been customary to first mold or form thecasing in ashape desired and cover its inner surface with a solution of tin, after which the liquid antifriction metal is poured uniformly'over the inner surface ofthe casing, the coating of body of anti-friction metal 5, which has a tin being relied upon to unite the two metals.
This construction, however, has proven ineffective to prevent the anti-friction metal from getting loose under the stress of the pounding blows imparted to the hearing by the axle box and the end thrusts of the axle. By myconstruction, however, the body of anti-friction metal ismore-firmly secured within thecasing, and is held fixedly therein in such manner as to resist effectively the pounding blows imparted :by the axle the casing being preferably provided with 1 box, as well as the end t hrusts of the axle.
By constructing the arch of the casing upon an arc of greater radius than that of the axle I am able to provide a greater thickness of the anti-friction metal in that portion of the bearing upon which the load is borne, thereby greatly increasing the life of the bearing and enabling the car or other vehicle equipped with the hearings to be run a relatively greater mileage without the necessity of replenishing the anti-friction metal in the bearing.
Having described my invention what I claim as new, and desire to secure by Letters Patent, is:
A hearing of the class described comprising a casing provided with a pair of-oppositely disposed longitudinally extending shoulders and having a longitudinally exeoaa: s
tending dove-tail shaped recess in the crown portion of its arch a plurality of elongated apertures in the side portion of its arch, and a body of shoulders and having portions thereof located within said recess, said bearing metal 'radually increasing in thickness from'it-s edges toward the portion thereof located in the recess provided in the arch of the casing whereby the axle may utilize a portion of the bearing metal within said recess.
In testimony whereof I atfix my signature,- in the presence of two witnesses.
EDGAR PEGKHAM.
