SPECIFICATION forming part of Letters Patent No. 370,722, dated September 27, 1887.

Application filed July 9, 1886. Serial No. 207,553. (No model.)

To all whom it may concern:

Be it known that I, GEORGE M. BRILL, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Car -Axle Boxes, of which the following is a specification, reference being had therein to the accompanying drawings, wherein- Figure l is a longitudinal section, partly in elevation, showing an axle-box embodying my improvements. Fig. 2 is a plan in detail, showing screw or bolt and nut and lug for nut for Fig. 3 is a cross-section of part of box and axle, showing in elevation the oiling device for the axle. Fig. 4 is a perspective, partly broken away, of frame of oiling device. Fig. 5 isaperspective showing preferable form or configuration of iibrous material for the oiling device. Fig. 6 is a longitudinal section of the oiling device. Fig. 7 is a rear View of axle-box lid. Fig. 8 is an elevation of key for front end of axlejournal to prevent end movement or thrust of the axle. Fig. 9 is a plan of axle-bearing. Fig. 10 is an elevation of pressure-rings for the dust shields or plates of the axle-box. Fig. ll is an elevation, partly sectional, showing front end view of axle-box with depending brackets or lugs engaging with stops on the truss or brace rod to prevent side movement of axlebox, and also bearings for the supporting-springs, part of car, and a wheel for same; and Fig..l2 is a plan, partly sectional, of bracerod and axle-box lugs shown in Fig. l1.

My invention has relation to axle-boxes and their spring-supports; and it has for its objects to provide asimple and effective form of dust-shield for the rear end of the box and for the lid or its joint; a brass or bearing having tapered ends provided with vertical corner beads to adapt it to be removed for replacement, or for other purposes, through the front end of the box while it is ou the car, and without removing or displacing any of the parts of the box except opening its lid; asimple, eective, and durable oilin'g device composed of a metal frame having packing or layers of brous material arranged to feed the oil tothe sides of the journal and rise in the box with the journal as its bearing wears away;

abutting lugs for preventing side movement of the box; a closed oil-well integral with the axle-box and which is filled from the interior of the box; and supports for the springs for the car, which supportsare arranged to obviate chafing or wearing of the springs.

My invention accordingly consists of the combination, construction, 'and arrangement of parts as hereinafter described.

In the drawings, A represents the axle-box, the front part of which is open, as shown at a, and the front edges, a', of its sides a2 are made rounding, as indicated, and are more or less finished to make said edges smooth. At the bottom of opening a and on the front of the box -are formed lugs a3, having curved recesses a'L of any suitable shape. The opening a is closed by a lid, B, which is curved correspondingly to the outline of opening a, and said lid rests or bears upon the finished front edges, a', of the sides a2 and upon the upper side of the top a5 of box A. The bottom edge, b, of the lid is shaped or curved to correspond with and snugly iit the outline of the recesses o* in lugs a3 to hold the bottom part of the lid securely in position.

At the upper part of the lid B is formed a projecting central lug, b', having an opening, b2, for1 the passage of a bolt, b3, which screws into a nut, b4, resting or cast in a lug, a6, on the top of the box, as shown in Figs. l and 2, the lug a being preferably formed with opentop transverse slot al, so that the nut b* may be loosely placed therein, and with open longitudinal slot a for the passage of bolt b3, (seen more plainly in Fig. 2;) but any suitable construction of lugmay be employed. When the lid B is in position on the box, it is securely held thereon by the lugs a3 and the bolt b3, and by turning or screwing up the latter the lid is brought in close impingement with the curved edges a of the sides and with the top a5 of the box, to make a tight joint therewith; but to avoid any possibility of imperfectjoint between the lid and box, or to make a perfectly dust-tight joint, I prefer to line the rear side of the lid with a plate of spring metal, b, so that as the screw b3 is adjusted the spring-,plate b4* is subject to pressure between the lid and box to hermetically seal the joint between them. This plate may be secured to the lid in any suitable manner; but l prefer to cover the entire inner side of the lid with the plate b, as shown in Figs. l and 7, and to rivet it to the lid, the rivets b5 being placed within or away from the edges of thelid, so as to leave the edges of the plate free, loose, or flap-like, so that they will have more or less elasticity and admit of conforming more readily to the outline of the edges of the sides and top of the box, or to any imperfections therein when not finished or smoothed off. The rear end of the box is an open one and is preferably formed with a rearwardly-projecting annular flange, c, within which is another parallel annular flange, c', which does not project backwardly as far as the flange c, or the flange cis shorter than the flange c, and between these flanges is a wide annular space or recess, c2, into which passes an annular flange, d, projecting forwardly from a collar, D, suitably fastened to the axle Ein any desired manner. This collar D is separate from or has no connection with the wheels of the car; hence the box and its appurtenances herein described may be easily and economically applied to cars in service.

Between thc edge d of flanged and the side c3 of space or recess c2 is an annular ring, F, fitting snugly in space or recess cz and held in close impingement against the edge d of flange d by a spring or pressure ring, G, located between ring F and side d. The ringF is preferably prevented from turning by means of oneor more lugs, c, formed in space or recess ci, fittingin or engaging with slots f in the periphery of ring F, as plainly shown in Fig. 1.

The springs g for the ring G may be platesprings of any suitable shape, riveted or otherwise secured to the ring, as indicated in Fig. 10; or any other form of springs may be used. They impinge against the side c and press the ring G, and inturn the ring F, against the edge d' of flange d to make a tight joint therewith and form a shield for excluding dust from the interior of the axle-box.

Between the outer edge, c, of flange c' and the collar D is another annular ring, H,which snugly but loosely fits the axle and the interior of flange d, and is prevented from rotating by ribs or lugs d2 on the inside of flanged entering peripheral recesses 7L in said ring. Its front face abuts against the edge c5 of flange c', and is maintained in close impingement by a pressure or spring ring, G', loosely surrounding the axle and located between collar D and ring H, and constructed in a manner similar to spring or pressure ring G. The ring H therefore forms a second plate or shield for exelud ing dust or dirt from the box A. These dustshields F and H, being loose on their bearings, give with the axle as it moves longitudinally. During such movement, however, their contact with the box parts against which they bear is maintained by the spring or pressure rings. These shields, it will be noted, are so arranged that the larger one of them, 'or the shield F, is in advance of the smaller one, or the shield H, that the former has its bearing or closing surface against the edge of collarflange d, and the latter or smaller shield bears against the edge c" of box-flange c', and that shield F is supported upon the box and shield H upon the axle. This described arrangement ofthe two shields, it will be noted, provides a tortuous path for the travel of dust or dirt to the interior of the axle-box, and gives virtually two separate shields, so that if, by any possibility, any dirt gains access through or by the first shield, F, the second shield, H, bars its entrance to the box. The flange c is made deep, as shown in Fig. l, to form a guard or shed to exclude dust from the collar-flange d. The lugs c dl on box A and collar D and recesses f and h in shields F and H may be dispensed with, in which case the shields may rotate or be held stationary by friction or pressure of the spring-rings.

The shields may be made of wood, fiber, or any other suitable material. I prefer to make them of fiber, or one of fiber and the other of wood. The lower part of flange c' has its upper surface inclined downwardly to meet a false bottom, I, in box A, which bottom iuclines from its center to flange c andto the front vof the box. vided to conduct waste or surplus oil back to the oil-well fi of the box, which is located between the false bottom I and the bottom a of the box. The bottom or top I of the well has an opening, i', near the front of the box with removable plug t2, through which oil is filled into the well t'.

In the centerof the bottom l is an elongated opening, i3, in which loosely fits an oiling device, K, for the axle-journal c. This oiler is preferably composed of .a sheet-metal frame, K', having top k, in which are elongated side openings or slots, 7c', centrally located, depending sides 7a, and ends k3, with open bottom It* and upwardly-projecting side flanges or flaps, h5. To the latter and the sides k2 of frame li are secured T-shaped pieces of fibrous or wick-like material, L, the vertical limbs lof which pass down through the slots k to and, if desired, project below the bottom of frame K. The horizontal limbs l of the This inclination is pro-y l'OO IIO

fibrous material are substantially of a length equal to that of the flaps or flanges h5, and are tacked to the latter by stitching, as shown at Z, Fig. l, or any other suitable fastening may be employed. When stitched or similarly sccured to frame K, suitable openings, 1*, are provided for the passage of the thread. \Vithin frame K and at each end are placed, preferably, spiral springs M, held in place by cups or pins m, depending from the under side of frame top plate, 7c, as shown more plainly in Fig. 6. These springs rest upon the bottom a of the box and impart an upward spring-pressure to the oiling device. The flaps 765, with fibrous lining L, are spread apart to embrace the sides of the axle, as shown in Fig. 3, the sheet-metal flaps being elastic or flexible enough to permit this spreading, and the spring-pressure of the oiling dekzo vice,being annpwardone,maintains the fibrous lining in contact with the journal at all times during the vertical vibrations of the box and as the journal wears. The oiling device or its frame is of such an economical construction that when worn it ca-n be cheaply replaced by a like device. I

If desired, the upper end ofthe brous Inaterial L may project above the iiaps 795, as indicated in Fig. 3; but this is not essential.

Near the forward end of axle E is an annular groove,e, for engagement with an inverted- U or yoke shaped key, m', (see Figs. 1 and 8,) which key slides in vertical grooves am on or in the inner surfaces of the box-sides a, The tops of these grooves are in front of the front edge of the top of the box, so that when the lid B is opened or removed thekey m can be readily removed or inserted', as desired. `To facilitate removal, it is formed on its front side with a handle, knob, or lug, m2.

, The journal brass or bearing Pis made or formed with contracted or tapering ends p, having at its corners vertical beads, ridges, or ribs p' to adapt it to be taken hold of and drawn out through the box-opening a while the box is on the car or on the axle, the4 key m being first removed. The latter, itwill be noted, not only prevents end-thrust of the axle, but

also maintains the brass or bearing in position, and the usual or independent keys heretofore employed for the brass may be dispensed with.

lf desired, the groove in journal may bedispensed with, and the key then abuts against the end of the journal, as indicated by dotted line l l, Fig. 2.

The axle-box A is formed with side flanges or platforms, R, having spring-bearings r,and openings rbetween the bearings and the sides of the box. (See Fig. l1.)

To prevent undue lateral movement of the box, it may have depending lugsor brackets S, which abut against lugs ton the brace or truss rod T, located below the box, as shown in Figs. 1l and 12. The spring-bearings r of the latter have a central opening, r2, of a larger diameter than that of the stay-bolt t', for the reception or passage of a plunger, t2, depending from a plate or cap, t3, and surrounding the bolt t', as shown in Fig. 11.

Between the bearings r and cap t is a rubber spring or block, and as the lower edge of the cap-plunger t2 passes down into the bearing opening r2 said edge does not come in contact with sides of the opening in said rubber block, and all chafing,vwearing, or deterioration of said block is avoided. The cap t3 has on its upper side a pin, t5, for holding the lower end of aspiralspring, N, in position or line, and as this pin is within the mandrelhole of the spring any. dirt deposited thereon works off of the same over the top of the cap i3. The upper end'of spring Nis held in place by a cap, t, having a pin, t7, and between the cap andsill plate or cup o is a rubber block, n', and between truss or rod T and bearing r is a likeblock, o. This described construction fthe front side of the wheels.

of bearings for the springs and the arrangev opens from above downwardly; that the bottom edge of the lid has a loose interlocking engagement with the box to admit of such described manner of opening or removing the lid; that it has at its upper edge a bolt-andnut fastening with the box, which nut is preferably of wrought-iron, or is separate from andl loosely located upon the top of the box. The

vlid is not, therefore, a self-locking lid, but one that is locked by manually adjusting the bolt or fastening devices, and by suitably screwing up the bolt a varying pressure is applied to the free or flap edges of plate bi4 to make a,

tight joint between the lid and box. The loose nut being separate from the box, it is, when stripped, worn, or lost, readily replaced by a new one. It will be further noted that the collar D, with its flange for impingement against the dustshields in the axle-box, is separate from the car-wheels; that it is affixed to the axle and the box, and it may therefore be economically applied to' cars already in use without necessitating the removal of the wheels from their axles, and in building new cars the old form of wheels are used, as heretofore, and that the oil-well of the box is cast integral therewith, and the oiling device is composed of a metal frame, to which the oiling-pads are secured; hence as the pads wear they are detached from the frame and replaced by new ones.

The truss-bar arrangements and the combi' nation rubber springs and spiral springs, and the supports for the same herein shown, I do not claim, as they form the subject-matter of another application filed of even date herewith, Serial No. 207,522.

I am aware that car-axle boxes having rear open ends in which are placed one or more dust-shields, against which annular fianges or sleeves impinge to close the rear open ends of theboxes, are not new; but heretofore these flanges or sleeves were either an integral part of the wheel or were separate from and bolted to In the one case IOO IIO

the axle-boxes, as described, can only be applied to new cars, or to cars the wheels of which have the flanges or sleeves cast on them, and in the other, while the fianges may be bolted to old car-wheels, yet patterns of fianges or sleeves must be made to suit the different configured sides of different stylesof old wheels,and when in use the hammering of the wheels upon the railsloosens the fastening-bolts of the sleeves or flanges to impair their usefulness. In either case, however, when these wheel anges and boxes are used upon cars for narrow gage of track wherein the wheels in practice are located some distance from the car-sleepers or from the axle-journals, the wheel-flanges must be extended to meet and enter the rear end of the axle-boxes, or extra sills must be secured to the side sills of the ears,in order to provide for locating the boxes within suitable range or distance of the flanges.

Upon different gages of roadway, as the distance from the axle-journals to the sides of the wheels vary, the exact degree of extension for the fianges or the width of the extra sills also varies, and no standard gage can be made when the flanges or sleeves are secured to the wheels; but where the flanges or collars D upon the axle are used, as above described, a standard gage or point of location upon the axle is allowable for all the variations in gage ofthe wheels of the car, and the axle-boxes are always located below the sleepers of the car; hence the main advantages to be de rived from the use of collar D upon the axle instead of upon the car-wheels are, the collars can be put as close to the axle-box as desired in different gage of cars. rlhe axle-boxes are thus always located directly under the carsleepers, which position is the proper one, and no extra carsill pieces or extension of flanges are necessary when changing the gage of ears.
