CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 312,181, dated February 10, 1885. Application filed July 21, 1884. (No model.)

To all whom it may concern.-

Be it known that we, J. GEORGE BRILL and EDWARD H. ZITZMAN, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Oar-Axle Boxes, of which the following is aspecification, reference being had therein to the accompanying drawings, wherein Figure l is a vertical longitudinal section of an axle-box embodying our improvements. Fig. 2 is a cross-section on line 1 1 of Fig. 1. Fig. 3 is an elevation of the followers for the dust-excluder or packing at rear end of the box, showing the springmechanism for obtaining the automatic movement of the followers for taking up the wear of the wood or packing-plates, the latter not being indicated. Fig. 4 is a broken top view of one of the followers. Fig. 5 is a side or edge elevation of a follower. Fig.6 is a broken horizontal section through the oil-conduit. Fig. 7 is atransverse section of a paddle or oil-torcing wheel having adjustable blades or paddles. Fig. 8 is a rear elevation of axle-box. Fig. 9 is a plan, partly sectional, ofsame; and Fig. 10 is a broken elevation of one of the wooden or packing plates for the d ust-excluder at rear end of box.

Our'inveniion has relation to improvements in aXle-boXes, having particular reference to devices for oiling the axle-journal and its bearing, to shields and packing for excluding dust and dirt and preventing leakage of oil from the axle-box, and to the formation of the axle and the box; and it has for its objects, first, to dispense with the usual waste in the oil-well of the axle-box and substitute therefor a force or paddle wheel mechanism and appropriate oil conductors or conveyers, whereby the oil is mechanically raised from the box oil-well to the top of the journal brass or hearing, and through which said oil finds its way to the axlejournal; second, to provide an axle having a reduced portion or diameter in rear of the journal, and separated from the latter by a collar, said reduced portion having its location in the rear wall of the box, and serving to prevent leakage from the box of any surplus oil supplied to the axle-bearing; third, to provide an axle-box with an open top and a double chambered or recessed rear wall, each of which has a dust-excluder packing; and, finally, to provide a dust-shield so constructed that it antomatically takes up its wear. Our invention accordingly consists of the combination, construction, and arrangement of parts, as hereinafter described and claimed.

In the drawings, A represents an axle-box, which may be of any suitable construction and design and be provided with any desired form of lid and usual appurtenances; but we prefer to make it with an open top, a, which is closed by a cap or cover, B, extending the length and width of the box, as shown, or otherwise, as desired. Both the cap B and box A are formed with aligning vertical openings 0, through which pass bolts C, as more plainly shown in Fig. 9, for'securing said parts, or firmly bolting them together to form a tight joint between them, their meeting surfaces or edges being finished, if desired, or provided with a gasket or other packing. On the bottom and sides of box A, or otherwise located, are guides or slotted brackets d,which receive sliding or vertically-moving bearing-blocks d, resting upon springs or other elastic supports, (1", the tendency of which is to move the blocks d upwardly, or away from the floor or bottom of box A.

In blocks dis journaled a shaft, (Z on which is mounted awinged or paddle wheel, D, having end disks or collars, D D, the periphery of which extends beyond the outer edges, f, of the paddles, wings, or blades F. The shaft (1 and paddlewheel I) may be separately made, as shown, and aresuitably connected; or they and the blades F may all be formed integral. Each of the blades F may bein one piece of metal or other material, as indicated in Fig. 2, or be composed of sections f and f the'latter being radially adjustable upon the former, as represented in Fig. 7, and are made of leather, rubber, or other flexible material.

Upon the inner walls of the sides of box A, and at its forward end, are brackets g, having upper open end slots, into which passes a transverse check orguard bar, G, for preventing undue end movement of axle H.

On the inner wall of one of the sides of box A are dovetail or other grooved tenons or bolts 0, which pass through elongated openguide-bars, i, which receive and firmly support a removable conduit or pipe, I, which extends upwardly along one side of the axle and is bifurcated at or near its upper end to provide two outlets, it", bent at i and projecting into chambers or recesses 75 of brass or hearing K. The mouth or inlet 13 of conduit I is located opposite to and below the lower half of the paddle-wheel D, as shown more plainlyin Fig. 2. The brass K has a central segmental or other configured transverse slot, 76, into which enters a correspondingly shaped and located rib, b, on cap B, to form a key for holding the brass in position and for preventing longitudinal movement of same.

From the brass chambers or recesses lead vertical or radial openings 7t", for conducting the oil supplied to said chambers to the axlejournal. The operation of oiling the latteris as follows: The springs d hold the disks D of the paddle-wheel D in close contact with the journal h, so that as the latter revolves it communicates a rotary motion to the paddlewheel D, whose blades sweep or force the oil in well a into and up the conduit I, and thence into the brasschambers 7r, from which it flows by way of openings 76 to journal h. The wear of the disks D is automatically taken up by the springs (1 The axle-box A has a triple rear wall, A A A inclosing vertical chambers A* and A, of which the former has an open bottom, a, and the latter an open top, u These walls are provided with the usual oval openings for the passage of the axle H, which has that portion of its length which is located in chamber A reduced in diameter, as shown at if, so as to provide a collar, h, between the journal h and the reduced portion 71. for preventing surplus oil on the bearing or journal traveling back of the latter and leaking from the axle-box. To further avoid the last-named result, or to provide additional means for preventing oil-leakage from the box, and also to exclude dust therefrom, we place a guard or shield, L, in chamber A. This guard is composed of two oppositely-arranged tapering or wedge-shaped followers, M M, having central openings or slots, on, for the passage of axle H, and flanges m,with ribs or tenons m at one of their edges or ends, as more plainly shown .in Fig. 3.

Upon or attached to each follower is a wood or other suitable plate or packing, N, having central axle-openings, a, as illustrated. The outside surfaces, n, of these plates are provided with grooves a", into which are fitted gum or other gasketsmiwhich impinge against the opposite or adjacent transverse walls of chamber A, as indicated in Fig. 1, and form a tight joint therewith. The followers M are so arranged that they contact or impinge upon one another between the wooden plates N to form a double wedge, (see Figs. 1 and 3,) the ribs m of the followers entering plows or recesses n in the plates N. Said followers are loosely secured together by ings 0 in their flanges m. See Figs. 4 and 9.) These bolts 0 project below the flange m of the lower follower, M, and are provided with expanding spiral or other springs, 0", a connecting spring seat or plate, 0", and fastening and adjusting nuts 0. Each plate N is kept in position upon its respective follower, so as to move therewith, by the rib m of the follower entering the plow or recess a of the plate. The expansive action of the springs 0 against the flange m of the lower follower and the spring-plate 0 tends to exert a downward pressure upon the upper follower and its plate N, and upward pressure upon the lower follower and its attached plate, or tends to move or slide the followers upon one another, and, as they are tapering or wedge shape, any vertical movement of the followers moves the plates N N laterally farther apart from one another, orincreases the thickness ofthe guard or shield L in the direction of the axis of the axle to always automatically keep the gaskets n of plates N in close contact with the contiguous walls of chamber A and edges in n of the central openings of said plates in impingement with axle H, or its reduced portion h", as shown, and thereby form a dust-tightjoint between said parts, the wear of which is al' ways automatically tak en up by the expansive force of the springs 0". provides a dust-excluder, but it also prevents leakage from box A of any oil that may escape from the oil'well a or the journal bearing to the reduced portion of the latter.

In chamber A is placed a secondary dustexcluding plate or shield, P, composed of a single piece of vulcanite,or of the usual material now employed for dust-shields for caraxle boxes. If desired, however, said shield P and its chamber A maybe dispensed with. The cap B is provided with an extension, B, for covering the top of chamber A; but whenever deemed necessary such extension need not be used, in which case the chamber A will then be open at both its top and bottom.

The box A is shown provided with side supports, for the usual or other bearingsprings, and has openings (1 for the passage of the bolts which hold the bearing-springs and secure the axle-box to the car in the usual or well-known manner; but it is obvious that these spring-seats Q. are dispensed with when box A is placed in and has a vertical movement in the usual or other forms of pedestals.

If desired, oil-conduits I may be used on both sides of the axlebox, so that oil will always be supplied to the brass K, in whatever direction the axle may be rotated, or to provide for the lubrication of the axle-journal during a backward movement of a train or car.

If desired, the paddles of wheel D may be perforated to prevent undue resistance being offered to their passage or rotation through the oil in well or box A, and these perforations are plainly shown in Fig. 1.

It will be noted from the foregoing that the The shield L not only axle-journal is mechanically lubricated by the forcing of oil to its bearing, such forcing being effected by means of a paddle-wheel rotated by the axle; that a sectional follower dustshield having automaticallyacting mechanism for taking up the wear of its axle contact-surfaces is provided for excluding dust and preventing leakage of oil from the axle-box, and that the latter has an open top extending from end to end, whereby all the fixtures for the interior ofthe box may beeasily placed therein and removed therefrom for repairs, renewal,or otherwise.
