Application September 13, 1946, Serial No. clients 2 Glaims. r01. ans-i9) Our invention relates I to waste retainers for use in the journal boxes of ra'lway cars in babbitt bearings are used. At the present time considerable trouble and eypense is causedby particles of cotton waste workinginbetween the bearing (usually termed the brass) and the journal. These particles wipe the lubricant in the journal box from the journal during rotation of the latter, with the result that a hot.- box is soon developed. which will cause destruction of the bearing unless the train is stopped in time and the trouble is rectified. By equipping the journal boxes with our devices the cotton waste is retained in its proper place in the lower portions of the boxes and prevented from work-, ing in between the bearings and the associated journals. 7

Our devices are so constructed that they can be readily installed or removed from the journal boxes without disturbing any parts of the latter. The devices are of simple andinexpensive construction and since there is little or no" wear thereon will last over a long period of time.

Other features will hereinafter appear and in order that the invention may be fully understood reference will now be had to the accompanying drawing, in which:

Fig. l is a cross section of the journal box on line l--l of Fig 2, with our device and the journal in position therein, the journal being partly in section.

Fig. 2 is a longitudinal sectional view of the journal box with the journal and our device arranged therein.

Fig. 3 is a perspective view of one of the devices.

Referring in detail to the different parts-disclosed by Figs. 1 to 3, inclusive, 2 designates. a journal box which may be of any preferred or conventional form. Mounted in the journal box 2 is a journal 4 having a collar 6 at one end. Mounted upon the journal 4 is the usual brass or bearing 8, which is curved at its under babbitted portion to snugly fit the journal 4, where it is held by a wedge l0. Lateral and longitudinal movements of the journal bearing 8 upon the journal 4 is prevented by the usual lugs l2 formed integral with opposite sides of the bearing 8, and lugs l4 formed integral with the inner side walls of the journal box 2.

The foregoing construction of the journal box and the interior parts thereof may be of conventional construction.

Referring now more particularly to our invention, l6 designates our device which, preferably but not necessarily, consists of one piece of tubing l'l be'nt sutstantiany into tlfl form Shown by Fig. 3. The evice is approximatd of uform' when news from the front end, which latter comprises a transverse element 58, formed I into a tense spring 20 intermediate its ease for a purpose which will hereinafter appear. The opposite ends or the transverse element were bent upwardly a short distance as indicated at 22, thence backwardly to provide lower longitudinal members 2 5 which are curved upwardly and rearvvardly at their rear ends to provide elements 25, the upper ends or which are bent forwardly to prdvide up erl'ongitudinm mem bers 28:, which are,=bent' downward to provide front elements 30., fixed at theirlowerends to the lower longitudinal members 24. The front elements 30 are arranged far enough from the transverse element I8 to admit the journal collar 6', as shown by Fig. ,2. without contactingsj'a i'd' collar. The rear and' front elements 26 and 38, respectively, are inclined upwardly to bring the upper I longitudinal members 28 closer together than the respective lower longitudinal members 24 for a purpose which will hereinafter appear. Preferably the longitudinal members 24 and 28 are arranged approximately in parallelism as shown. The uppermembers 28 are provided with longitudinal slots 32, in which the outer longitudinal edges of respective babbitt bearing members 34 are firmly secured by pressing the sides of the slots 32 toward each other to firmly grip said bearing members 34, the inner'confronting edges of which latter have series of notches 36.

By bending the tubing H as above described. a pair of approximately rectangular longitudinal frames 38 are provided.

In practice, the upper longitudinal members 28 of the respective frames 38 are grasped and spread apart to permit the rear elements 2s to pass the diametrically opposite sides of the journal collar 6, as the device is inserted through the customary front opening (not shown) in the journal box 2 and pushed backwardly until the transverse element l8 almost touches the journal collar 6. The device is then released to permit the frames 38 to be sprung toward each other by the coil spring 20 until the notched edges 36 of the bearing members 34 grip opposite sides of the journal 4 at points just below the oppositely disposed lower surfaces 40 of the journal bearing 8, and the upper longitudinal members 28 bear against the surfaces 40, as shown by Fig. 1. Thus the device is reliably held in place and prevented from shifting about in the journal box or coming into contact with the journal 4, except with the bearing members 34, as above described. When the device is being pushed back into the journal box 2, the inclined rear elements 25 slide over the usual supply of cotton waste without disturbing the latter, and when the device is released it presses down upon the cotton Waste and holds it in place. When in position in the journal box 2 no part of the frames 38 are in contact with the journal 4, the collar 5, or the inner walls of the journal box 2, so that the only wear on the device will be along the notched edges 36 of the bearing members 3 3. When the bearing members 34 become worn out the device is removed from the journal box so that the worn out bearing members may be removed from the slots 32 and replaced by new bearing members.

When the device is in position in the journal box as stated, the bearing members 34 effectively prevent any of the cotton waste from working between the journal 4 and the journal bearing 8, so that undue wear of said journal bearing 8 is prevented. The notches 36 permit lubricant in the journal box to be carried upward between the rotating journal 4 and the journal bearing 8, thereby preventing the latter from becoming overheated for lack of a lubricant. Y

From the foregoing description taken in connection with the drawing it is apparent that we have provided simple, efiicient and inexpensive devices possessing the advantages above pointed out, and while we have shown a preferred form of our invention we reserve all rights to such changes or modifications thereof as properly fall within the spirit and scope of the invention as claimed.

Having thus described our invention, what we claim and desire to secure by Letters Patent, is:

1. A waste retainer insertable horizontally in a journal box, comprising one piece of tubing bent to provide a pair of approximately rectangular side frames spaced apart and comprising a pair of lower longitudinal members, a pair of upper longitudinal members, front and rear elements connecting the longitudinal members of each frame, the lower longitudinal members extending forward a predetermined distance beyond said front elements, a resilient transverse member connecting the forward ends of the lower longitudinal extensions, and confronting bearing members secured to the upper longitudinal members and adapted to bear against a journal.

2. The combination with a journal box, a journal in said journal box, and a brass mounted upon said journal and projecting laterall beyond opposite sides thereof; of a pair of approximately rectangular. frames spaced apart and arranged at opposite sides of the journal, said rectangular frames including upper horizontal members adapted to bear against the under surface of the laterally projecting portions of the brass, bearing members secured to said horizontal members and provided with confronting notched edges, and a resilient transverse member connecting the frames and adapted to press them towards each other and thereby press the foregoing notched surfaces against opposite sides of the journal.
