MICHAEL JOSEPH OHARA, OF NElI ORLEANS, LOUISIANA.

ANTI-FRICTION JOURNAL=BEARING.

SPECIFICATION forming part of Letters Patent No. 391,184, dated October 16, 1888.

Application filed June 12, 1888.

T0 aZZ whom it may concern.-

Be it known that I, MIoHAEL J osEPH OHARA, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and nsefullmprovements in a Journal for Starting a Car; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in lubricatingjournal-boxes of the class in which friction-rollers are employed; and it consists in the construcliomnovel arrangement, and adaptation of devices, as will be hereinafter more fully set forth, and particularly pointed outin the claim appended.

In the accompanying drawings, Figure 1 is a vertical cross-sectional view of a car-axle spindle, the same continuing through my improved axlc-box andlubricator. Fig.2isa horizontal sectional View of the box removed from the axle-spindle. Fig.3 is a plan view of the box. Fig. 4 is a detail view of one of the frietion-rollers which I employ, and Fig. 5 is a view of one of the bearings for the said rollers removed from the box.

Referring by letter to the said drawings, A indicates an axle-spindle, which may be that of a streetcar axle.

13 indicates my improved axle-box, which is of a form substantially as shown, and provided in its upper side longitudinally with an oil or lubricant receptacle, A,which may be covered with a suitable plate or top to prevent rapid evaporation and exclude dust, dirt, and the like. This box B is, furthermore, provided at opposite sides with longitudinal vertical flanges, which depend from the receptacle a sufficient distance and are adapted to embrace the axle-spindle, as more fully shown in Fig. 1 of the drawings.

Serial No. 276,891. (No model.)

C indicates bearing-blocks for friction-rollers, the form of which is better shown in Fig. 5 of the drawings, and there is one of these blocks employed transversely at each end of the box beneath thelubrieant-chamber. These blocks are grooved vertically at opposite ends, as shown at d, to receive tongues or projections 6, formed at opposite points on the inner sides of the vertical flanges of the box B, so that the said blocks may be prevented from lateral displacement and yet allowed to adjust themselves with respect to the aXIespindle.

D indicates the friction-rollers, which have an upper bearingin the seatsf of the blocks 0, and these rollers have spindles, as shown atg, to enter the seatsf of the block 0. It will be observed that these rollers extend the entire length of the box beneath the lubricant-reeep tacle, and that the floor of the said receptacle is provided with small apertures h, so that the lubricating material may be fed upon the friction-rollers and from them discharged on the spindle ofthe axle. It will be observed that these rollers have a bearing upon the axle spindles.

Having described my invent ion, what I claim is The combination, with the axle-box having the upper lubricantreceptacle provided with a perforated bottom and the depending flanges adapted to embrace an axle-spindle and provided with the tongues, as shown, of the bearingblocks grooved at opposite ends to receive the tongues on the flanges of the box, and the frictiourollers arranged above the axle-spindle and having an upper bearing against the said blocks.

In testimony whereof I affix my signature in presence of two witnesses.

MICHAEL JOSEPH OHARA.
