UNITED STATES JAMES G. BLUN'I, OF SCHENECTADY, NEW YORK.

HUB LINER FOR RAILROAD VEHICLES.

Application filed May 14,

To all whom it may concern:

Be it known that 1,, JAMES G. BLUNT, a citizen of the United States, and a resident of Schenectady, in the county of Schenectady and State of New York, have invented a certain new and useful Improvement in Hub Liners for Railroad Vehicles, of which improvement the following is a specification.

The object of my invention is to provide a hub liner or wear plate, which will absorb the lateral pressure exerted by the wheel hubs against the faces of the journal boxes of railroad vehicles in passing around curves, and to so construct and install said appliances that the removal of old and worn out ones, and their replacement by new ones, may be effected without removing the j ournal boxes or disturbing any other part of the vehicle, thereby minimizing the time and labor required for such operations.

The improvement claimed is hereinafter fully set forth.

It has usually been the practice to apply to the face of a journal box, a liner of suitable material, secured to the journal box by screws or rivets, or by welding. It will be obvious that when such practice is followed, the removal of the journal box from the vehicle, becomes necessary, in order to effect the replacement of a worn out liner. My present invention applies a sectional liner, the members of which are so constructed and connected as to be held securely in position when in service, and to be readily separable and removable, for replacement by a new liner, whenever desired.

In the accompanying drawings: Figure 1 is a vertical axial section through a journal box and wheel hub, illustrating an application of my invention in connection therewith; Fig. 2, a horizontal axial section; Fig. 3, a front view, in elevation, of the liner, the side which faces the wheel hub being shown; Fig. 4, an isoletrical view of the same, the side facing the journal box being shown; and, Fig. 5, a partial horizontal sec tion, through a section of the liner.

In the practice of my invention, referring descriptively to the specific embodiment thereof which is herein exemplified, a wear plate or liner, 2, is interposed between the outer end of a journal box, 1, and the hub of the adjacent wheel, 4, said liner being of sectional construction, and comprising two counterpart members or sections, each of substantially L shape, which are detachably 1924. Serial N0. 713,211.

connected by a bolt, 3, passing through flat bottomed lugs, 2, on the tops of the sections, adapted to rest on the journal box, and engaged by a nut, 3

A. dovetailed tongue, 2 is formed on each of the sections of the liner, 2, said tongues being downwardly and inwardly inclined towards the vertical central plane of the liner, their outer sides being undercut or inwardly inclined, and their outer sides: perpendicular to the faces of the liner sections. The tongues, 2 fit in grooves, of corresponding transverse section, and longitudinal inclination, in the outer face of the j ournal box, 1. Flat faces are thereby presented, against which the connecting bolt, 3, pulls, when under the tension of its nut, The under sides of the bolt lugs, 2 are flattened, in order to rest on the top of the journal box, when the sections of the liner are in their correct vertical positions, in which the adjoining faces of the liner sections are not in contact, but stand slightly apart, so that, when tension is applied to the bolt, it is resisted by the inner sides of the inclined tongues, bearing against the corresponding 1ianner sides of the grooves in the journal An open topped oil recess, 2, is formed on the top of each of the liner sections, adjacent to the bolt lug, 2*, thereof, said oil recesses communicating, through passages, 2 with oil grooves, 2 in the faces of the sections adjoining the wheel hub. Oil is thereby permitted to be supplied to, and spread over, the entire faces of the liner sec tions, its application reducing materially the rapidity of the wear thereof. Lubrication of liner faces has always hitherto been diflicult of accomplishment, and in the absence of effective means, is often neglected, with the result of more rapid wear than if proper lubrication is provided for.

Inasmuch as an easy sliding fit is maintained between the dovetailed tongues of the liner sections and the corresponding grooves of the journal box, when replacing worn liners, it is only necessary to remove the connecting bolt, when each section of the liner can be slid out, in an upwardly inclined direction,-parallel with the tongues, and new sections be slid into place, and secured by tightening the nut on the bolt. It will be seen that when the liner is applied, and the nut of the connecting bolt drawn to a tight bearing, the liner will be securely locked in position, as the contact of the bolt lugs with the top of the journal box prevents the liner from dropping, while the tension of the connecting bolt counteracts any tendency of the liner to rise out of the upwardly diverging grooves of the journal box.

I claim as my invention and desire to secure by Letters Patent:

1. The combination, with a journal box and a Wheel and axle of a railroad vehicle, of a liner, interposed between the journal box and wheel hub, and comprising two separate L-shaped sections, each having a flat bottomed lug to rest on the journal box, an oil recess adjoining said lug, and an oil passage, extending downwardly therefrom substantially throughout the depth of the section; and a bolt passing through said lugs to lock the sections in place, the vertical legs of the sections each having an inclined undercut rib adapted to fit in a correspondingly shaped groove in the end face of the journal box.

2. A hub liner, composed of two counterpart L-shaped parts adapted to be independently inserted downwardly between the end of the journal box and the wheel hub, each part comprising a vertical leg and a horizontal top portion, each top portion having an upstanding perforated lug provided with a horizontal under surface adapted to rest on the journal box, the inner face of each leg having an inclined rib adapted to fit in a corresponding groove in the end face of the journal box, each top portion having an oil cell and a duct leading therefrom to the outer face of said top portion, said outer faces and the outer faces of said legs having oil grooves communicating with said ducts, and a bolt passing through said lugs to secure said parts in place.

3. A hub liner, consisting of two counterpart L-shaped parts, the vertical leg of each part having an inclined rib, the outer side of which is undercut, adapted to fit in corresponding grooves in the end face of the journal box, and the horizontal tops of the parts being each provided with an upstanding and inwardly projecting apertured lug adapted to rest on the top of the journal box, and a bolt passed through said lugs to secure the parts in place.

JAMES G. BLUNT.
