SECTIONAL JOURNAL BOX AND I-IUB LINER.

Continuation of application Serial No. 482,514, filed July 5, 1921.

This application filed January 28,

1922. Serial No. 532,436.

To all whom it may concern Be it known that I, CHARLns N. BARTON,

' a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Sectional Journal Box and I-Iub Liner, of which the following is a specification, reference being had to the accompanying drawings and to the letters and figures of reference marked thereon.

This invention relates to liners for wheel hubs and journal boxes and is designed for the purpose of reducin lost motion of the journal boxes longitudinally on axles or shafts, or of axles or shafts relatively to the journal boxes, especially in locomotives, the invention having reference more particularly to improvements in sectional journal box and hub liners of the character disclosed in my application for Letters Patent filed July 5, 1921, Serial No. 482,514, of which this is a continuing application for Letters Patent.

An object of the invention is to provide a liner of the above-mentioned character which shall be so constructed as tobe adapted to be very securely and reliably held in place under the severe conditions of operation of locomotives, and which may be readily applied to wheel hubs and journal boxes and be quickly and easily replaced when necessary.

Another object is to provide locomotive wheel hubs and journal boxes with sectional liners which shall be so constructed as to be enabled to withstand the strains imposed upon them in operation by frictionalcoir tact with adjacent elements, and not eopardize the devices whereby the sections of the liners are connected together.

A further object is to provide an improved sectional hub or journal box liner including improved means for securing the liner in place on an axle or shaft so as to not be liable to be broken or damaged in use, and which may be advantageously and inexpensively constructed and applied either to new machinery or to machinery 1n which lost motion may have developed in service, which also shall be reliable, durable and economical in use.

/Vith the above-mentioned and other obects in view, the invention consists in a liner holder or core having novel structural features, and a liner having also novel structural features whereby to removably lock it securely to the holder or core, and the invention consists also further in the parts and combinations and arrangements of parts as hereinafter particularly described and further set forth in the appended claims.

Referringto the drawings,Figure 1 is an elevation of a locomotive wheel and axle, representing particularly the outer side of a trailer wheel of a modern loconlotive, the axle journal being on the outer side of the wheel as is preferred in some cases, the outer side of the hub of the wheel being provided with the improved liner as a sufficient illustration of the purpose of the liner as a substitute for the worn away face of the hub which it is commonly known operates against a journal box on the axle journal; Fig. 2 is a sectional elevation of the wheel and axle, the periphery or edge of the hub liner on the wheel being seen; Fig. 3 is a fragmentary section of the wheel hub on an enlarged scale, the holder or core of the liner being shown in central section transversely with one section of the liner thereon; and, Fig. 4: is a front face view of the improved liner holder and the liner sections thereon, being partially broken away, the sections of the liner being separated as when about to be secured to the holder or core.

In the different figures of the drawings, similar reference characters indicate corresponding or like elements or features of construction herein referred to in detail.

In the drawings, the numeral 1 indicates the rim portion of a wheel, in some cases having a separate tire, the wheel having a hub 2 in which is a bore 8 receiving an axle 4 having a journal 5 projecting beyond the outer face of the hub. The hub has a suitable number of bolt holes 6 ex tending from the outer face thereof, the holes being necessary to receive securing bolts in case the holder or core of the liner is made separately from the hub and applied to permit it to be placed on an axle in case the axle journal is on the inner side of the wheel, or to permit the holder to be placed on the axle when not convenient to place it over the end of the axle or journal. The

holder plate has a suitable number of bolt holes 9 therein that receive bolts 10 inserted in the bolt holes (3 whereby the holder is firmly secured to the hub. The holder has a cylindrical peripheral portion 11 at its rear side from which a peripheral rib 12 extends adjacent to the front side of the holder. The rib has a suitable number of lugs 13, 14, 15 projecting therefrom, on one side of the axis of rotation, and similar lugs 13, 14: and 15 on the opposite side. The lugs 13 and 13 are diametrically opposite each to the other as are the remaining lugs similarly indicated. The holders are made rights and lefts and designed to be applied so as to be most el'licient when rotating in the direction resulting from forward movement of the locomotive. To this end the ends of the lugs are shaped so as to approximate the forward and rearward edges of saw teeth; but in order to be enabled to apply the liner sections to the holder closely without lost motion the ends of the lugs on one side of the holder differ each from the other; so that the forward ends 16 and 16 each correspond approximately to a radial line, the rearward ends 17 and 17 of the lugs 13 and 13 respectively being inclined or beveled and preferably curved slightly so that the end is convex. The lugs 14 and Id have concavely curved undercut forward ends 18 and 18 respectively and sloping convexly curved rearward ends 19 and 19 respectively, the inclination of'the ends relatively to radial lines being greater than the rearward ends of the first-mentioned lugs. The lugs 15 and 15 have undercut concavely curved forward ends 20 and 20 respectively and convexly curved sloped rearward ends 21 and 21 respectively, the

inclination of the ends relatively to radial lines being greater than that of the adjacent lugs.

The wearing parts of each liner designed to be renewed comprises two segmental sections having semircircular face plates 22 and 22' respectively that are arranged together on the front of the holder or core 7, and they have lateral rim portions 23 and 23 respectively that embrace the peripheral rib 1.2, the remaining portions having lips 24 and 24: respectively that engage the rear side of the rib. The rim portion of one of the liner sections has slots 25, 26 and 27 therein to receive lugs 13, 1% and 15 respectively, the companion section likewise having slots 25, 26 and 27 to receive the remaining lugs respectively. The ends 28 and 29 of the slot 15 correspond in contour to the ends of the lug 13, the ends 30 and 31 of the slot 26 corresponding to the ends 13 and 19 respectively of the lug 14, the ends 32 and 33 of the slot 27 corresponding to the ends 20 and 21 respectively of the lug 15. 29 corresponding to the ends of the lug 13, the slot 26 having ends 30 and 31' corresponding to the ends of the lug 14', the slot 27" having ends 32 and 33 corresponding to the ends of the lug 15. The curvature of the ends of the lugs and the slots correspond to the curvature of circles whose centers are approximately at twgo points 3 1 and 3 1 on diametrically opposite portions of the periphery ofthe rib 12, in order that the sections may be easily turned about said points to swing them onto or from the holder or core and permit the slots to receive the lugs in close fitting arrangement. The two sections are identically alike and therefore interchangeable, the lugs on the holder being spaced apart accordingly.

The two sections may be variously secured together on the holder, but preferably are bolted together, one section having ears 35 and 36 at its opposite ends, the other section having similar ears 35 and 36 on its ends respectively, one of the ears on each section having preferably a screw-threaded bolt hole 37 and the other ear a smooth bolt hole 38, permitting bolts 39 and 39 to be turned in the smooth holes and screwed into the threaded holes, lock nuts 10 and 10 being placed on the bolts as safeguards against the bolts becoming loose.

It should be understood that larger sizes of liners for use on driving wheel hubs and driving boxes may be provided with. a relatively larger number of lugs and slots than indicated, and in some there may be a smaller number.

While the preferred structure has. the particular lug contours above described it should be understood that fairly good results may be obtained by means of lugs having other contours, as for instance, the ends of the lugs may all be straight and parallel each to the other, permitting the liner sections to be moved squarely each towards the other when applying them to the core.

In practical use the plates 22 and 22 of the sections wear away, the side friction thereon having a tendency to turn the liner Lilrwise the slot 25 has ends 28 and j on its holder or core, but the tendency is resisted by the gripping actions of the lugs on the holder which tend to draw the sections inwards to the holder, this being an advantage especially in case one or both of the securing bolts become loose or lost. In case of loss of both securing bolts the sections of the liner may be retained on the core until rotation ceases, when one or both of the sections might fall from place with no serious results. When a liner has become worn away until it is practically useless the sections are readily disconnected from the core and new sections applied as before to the holders or cores.

Having thus described the invention, what is claimed as new is 1. A. sectional journal box and hub liner having an annular holder provided on its outer edge with a plurality of projecting lugs, and a plurality of segmental sections having slots receiving the lugs and provided with means to secure the sections together.
