AUTOMATIC OILE R FOR JOURNAL-BOXES.

Specification of Letters Patent.

Patented Get. 29, 191d.

Application filed. April 9, 1918. Serial No. 227,517.

Toall whom it may concern:

Be it known that 1, JOHN GOTI-INER, a citizen of the United States, residing at Superior, in the county of Douglas and State of Wisconsin, have inventedcertain new and useful Improvements in Automatic Oilers for J ournal-Boxes, of which the following is a specification.

This invention relates to the subject of lubrication, and has particular reference to an improvement in devices for automatically oiling the journal of the axles of railway rolling stock disposed within the journal To this end the-invention contemplates a novel and practical lubricatingdevice of the roller type which may be readily inserted in the journal box and held in proper relation to the axle at all times, and which is provided with a special bearing for its journal ends which will contribute materially to the life of the device and at the same time enhance its value from a, practical and eco nomical stand-point. That is to say, it is proposed to provide a device of this character wherein the lubricant supplying roller has a novel safety mounting, whereby it the support for one part of the journal breaks down another is automatically provided to permit the operation of the device in the usual way.

Another object of the invention is to provide a journal box lubricating device which may be readily handled as a com )lete unit,

that is inserted and reinovedfrom the box in its entirety, .and which when placed therein may be braced or held against displacement longitudinally within the box for the purpose of keeping the-lubricant feeding roller properly centered with reference to the end of the axle or journal disposed within the journal box.

A further object is to provide a devicefor automatically supplying lubricant from the well of the journal box to the axle in a thoroughly practical and efficient manner, while at the same time providing a device which permits of carrying a maximum amount of lubricant without increasing the size of the journal box. 'That is to say, it is proposed to provide a device which will not be open to the objection that its presence in the lubricant compartment of the journal box will displace a valuable quantity of oil.

With the above and other objects in; view Figure 1 is a longitudinal sectional view of a journal box illustrating the present improved roller mounting.

Fig. 2 is a horizontal sectional view taken on the line 22 of Fig. 1.

Fig. 3 is a perspective view of the hollow lubricant supplying roller.

Fig. l: is a detail perspective view of the shaft for supporting the roller showing its double diametered journal bearing end.

Similar reference characters designate corresponding parts throughout the several figures of the drawings.

Nhile it has been heretofore proposed to supply lubricant to the car axle disposed within the journal box by means of a roller or the like, these devices in many instances have failed after a relatively short period of use on account of the concentrated wear imposed upon the journal ends of the shaft which support the roller. In devices of this character it is necessary to yie'ldingly support the lubricant supplying roller so that it may be always maintained in contact with the axle which. rotates it, and the pressure thus imposed on'the ends of the roller-shaft to maintain this operative relation, causes the comparatively small ends of the said shaft to become rapidlyworn out, and frequently the roller drops from its support, and of course no lubricant is supplied to the axle.

Accordingly, in order to remedy this condition, the present invention proposes to provide a novel support for the roller, and a novel journal bearing end for the roller supporting shaft. That is to say, as will be observed from Figs. 1 and 2 of the drawings, it is proposed to provide a supporting plate designated generally as 1 having a central roller clearance opening 2 and the special journal bearing seats designated generally as S formed at each end thereof.

As will be seen more clearly from Fig. 1 of the drawings, these seats S each con- SlSij Of the

separate bearing sockets

3 and 4 arranged at different levels, and which may for the sake of convenience in manufacture be struck downwardly from the main body of the supporting plate 1 to provide the arrangement described, whereby the journal ends of the roller carrying shaft 5 may have an initial bearing in the upper sockets 3, and in case of necessity a final bearing in the lower sockets 4-. In carrying into effect this novelarrangement of bearing seats, it isof course proposed to provide opposite ends of the roller carrying shaft 5 with special journaled bearing ends which consist of the

separate spindle portions

6 and 7 which are of different diameter and are adapted to have a bearing engagement at different times, respectively in the sockets 3 and 41. That is to say, it is proposed to have the relatively small. spindle port-ions 6 initially bear in the upper sockets 3 of the plate, and so long as the said spindle portions 6 do not break or become worn off the spindle portions 7 will remain out of contact with the sockets 41. However, when either one or the other foregoing conditions exist, the sockets 4; will constitute a safety bearing for the ends of the roller carrying shaft. For the purpose of holding the journal bearing ends of the roller in the sockets, suitable holding straps 8 or their equivalent may be utilized.

In connection with the roller carrying shaft 5 having the novel journal bearing ends above referred to, it will be observed that the body portion thereof is preferably rectangular so that the roller R may be readily interlocked therewith in a simple and practical manner whereby either the roller R or shaft 5 may be readily renewed when the occasion demands. As previously indicated, in order to provide for the maximum oil. carrying capacity of the journal box, the said roller R is hollow, and therefore the end portions thereof are provided with a plurality of suitable openings 9, and a central rectangular opening; 10 for receiving the correspondingly shaped body portion of.

the shaft 5. This particular formation of the ends of the roller or drum R is especially advantageous not only because it permits the oil filling the entire interior thereof, but because it permits the shaft 5 to be readily inserted and removed when the occasion demands in a quick and easy manner, and of course involving little or no delay, in case it is necessary to make replacement while the vehicle is in service.

For the purpose of maintaining the lubricant supplying roller or drum R in frictional contact with the axle A, the said supporting plate 1 is yieldably supported at each corner by the springs 11 which surround the supporting posts or-feet 12 whose lower ends are adapted to engage with the bottom of the journal box while their upper ends have a slidable engagement through suitable openings in the corner of the plate to thereby permit the springs 11 tofexert their full force between the heads at the lower ends of the posts and the under side of the plate, and thus maintain the latter in proper elevated position.

Another important and practical feature of the present invention resides'in providing means for centering the roller in the bottom of the journal box in such a manner that it will always be in proper relation to the axle. That is to say, it is proposed to anchor the present device within the journal box in such a manner that the relative horizontal shifting of the axle will not displace the roller from its proper position. Heretofore, it has been generally necessary to remove the journal box to apply devices of this character for the reason that the same must be positively secured in position therein, and in order to do this it has been the custom to drill openings in the journal box to receive suitable fastenings for an choring the lubricating device. However, the present invention aims to provide a device which may be handled as a separate unit and which may be simply inserted in the journal box without the necessity of taking down the box or involving other an necessary labor.

Accordingly, to provide for holding the present device in position, it is proposed to provide the plate 1 with a novel anchoring device consisting of the oppositely disposed spring wire frame elements 13 which as will be observed from Fig. 2, are of substantially U-shaped formation, whereby their arm portions 1 1 may straddle the roller It and their free ends 15 which are of hook formation may engage with suitable openings 16 arranged in the body of the plate at each side of the roller clearance opening 2. Obviously the ends 15 of the centering frame elements 13 may engage with any one of the openings 16 whereby the transverse end portions 17 thereof may be spaced a greater or less distance from the end edges of the plate to engage with the interior walls of the journal box, and thereby space the plate the required distance from each wall. to maintain the roller R in engagement with the central portion of the axle A. For the purpose of steadying the spacing frames 18 in addition to their engagement with the plate at the openings 16, it is also proposed to provide the guide straps 18 or their equivalent adjacent the end edges of the plate 1 as shown in Fig. 2.

From the foregoing it will be apparent that the present invention aims to provide a hollow roller for supplying lubricant to the portion of the car axle within the journal box, said roller being detachably engaged with the shaft 5 which supports the same, and the said shaft having a novel journal bearing in a yieldingly mounted supporting plate which is capable of being accurately spaced and held within the journal box to center the roller with reference to the axle, the whole structure constituting a unit which may be readily inserted and replaced within the journal box with a minimum amount of labor, and expenditure of time.

Vithout further description it is thought that the many features and advantages of the present invention will be readily apparent, and it of course will be understood that changes in the form, proportion and minor details of construction may be resorted to without departing from the spirit of the invention or scope of the appended claims.
