n A u M BY ER WILLIAM F. BAUMEYER, 0F SPARTA, ILLINOIS.

HUB-LINER.

Application filed July 24, 1916.

T 0 all whom it may concern Be it known that I, WILLIAM F. BAU- MEYER, a citizen of the United States, residing at Sparta, in the county of Randolph and State of Illinois, have invented certain new and useful Improvements in I-Iub- Liners; and I do declare the following to be a full, clear, invention, such as will enable others skilled in the art to which it appertains to makeand use the same.

This invention relates to improvements in wear plates for locomotive wheels, particularly that'character of the device commonly known as a hub liner.

It is well known to those skilled in the art that modern locomotives are provided with very long rigid wheel bases, and therefore it is necessary to allow a considerable amount of lateral play between the wheel hubs and the journal boxes in order to prevent binding of these parts when the engine passes over curves. "The lateral thrust of the wheels against the journal boxes causes the parts to wear away very rapidly until in a short time the operation of the locomotive becomes dangerous.

It is the object of my invention to reduce the friction between the ends of the wheel hubs and the journal boxes by the provision of hub liners of simple and improved construction.

While there are many hub liners for this purpose on the market, none have proven satisfactory for the reason that it has been found diflicult to hold the sections together when they are made in more than one part, and to apply them when formed of a single )late. I l A hub liner constructed in accordance with my invention may be quickly applied without dropping the wheels or otherwise removing parts of the locomotive.

With this general object in View, my invention resides in the novel features of construction, combination, and arrangement of parts which will be hereinafter more particularly described and claimed and shown in the drawing wherein:

Figure 1 is a side elevation of my improved hub liner detached- Fig. 2 is a vertical section taken approximately on the plane of the line 22 of Fig. 1; Fig. 3 is an enlarged detail vertical section taken on the plane of the line 33 of Fig. 2; and Fig. 4

Specification of Letters Patent.

and exact description of the- Patented Dec. 12, 1916. Serial No. 111,085.

is a similar view 4% of Fig. 1.

Referring more particularly to the drawing in which similar reference characters indicate like parts, the numeral 1 designates a portion of a locomotive whee] fixed to the shaft 2 around which my improved hub liner 8 is disposed. This liner it will be seen consists of a circular plate formed of two sections 4 and 5, each of which is semicircular, the abutting edges being straight and preferably coinciding with a. plane pass ing through the center of said plate.

The plate is provided with a central circular opening 6 for the reception of the axle 2. The portion or section 4 of the plate has a longiti'idinally extending tongue 7 formed on its straight edge for disposition in a similarly extending groove 8 formed in the straight edge of the section 5. This arrangement holds the two parts of the plate together against lateral shifting relative to each other, and yet permits the plate to be readily applied about the axle without removing the wheel 1.

The plate is further provided with a circumferentially extending semi-circular groove 9 in its periphery in which the elements used for retaining the two parts of the plate together are disposed. At diametrically opposite points on the periphery of the plate and in the bottom of the groove 9 is formed a pair of sockets 10. It will be noted that the sockets of each pair are disposed a slight distance apart and that the plane passing through each pair is substantially at right angles to the plane of the straight edges of the sections of the plate. In other words the sockets in each portion of the plate 3 are formed in the cen ter of the grooved portion thereof.

In the groove 9 is disposed a pair of semicircular spring metal rods 11 which have their free ends bent inwardly toward each other to provide lugs 12, the latter being disposed in the sockets 10-when the rods are in operative position. The resiliency of the rods which are preferably formed of rather heavy spring metal, causes their ends to spring toward each other when they are removed from the plate, thus when they are in operative position they; will tightly grip on the periphery thereof and hold thevsections immovable.

It is obvious that in the use of this hub on the plane of the line liner that the two parts are separated and disposed around the axle 2 between the Wheel 1 and the adjacent journal box Without removing said Wheel, whereupon the spring metal rods 11 are disposed around and in the peripheral groove of the plate and the lugs forced into the sockets 10. Any thickness of plate may be used, depending upon the amount which the parts of the Wheel in the journal box have been worn, but in all cases, the means for holding the two sections together will be the same.

WVhen removing a plate for any purpose such as to place a thicker plate in position, the rods 11 must first be removed. In order to facilitate this removal one or more notches 13 are formed in either or both sec tions 4: and 5 at the periphery thereof. In the present case I have illustrated these notches as two in number and disposed in the portion 4 adjacent the sockets 10. These notches are so formed that a suitable hooked tool may be caught beneath one of the ends of each rod 9 in order to force the adjacent lug out of its socket.

As hereinbefo're mentioned, plates of various thicknesses may be used and it is also contemplated using the same in various sizes and shapes. Such a. device as this may also be used on machines or vehicles other than locomotives without departing from the spirit of the invention.

I claim:

A hub liner of the class described comprising a circular plate formed of two semicircular sections, the periphery of saidplate having a circumferentially extending groove therein, each section of said plate having a pair of sockets formed substantially at diametrically opposite points in the bottom.

of said circumferential groove, said sockets being disposed in planes at right angles to the line of divisionof said plate, a pair of substantially semi-circular spring metal bands removably disposed in said circum ferential groove and adapted to hold the two sections together, the resiliency of said bands causing the ends thereof to move toward each other to tightly grip said plate, and inwardly extending lugs formed on the free ends of each of said bands and at right angles thereto, said lugs being disposed in the aforesaid sockets.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
