EDGAR PEOKHAM, OF NE\V YORK, N. Y.

CAR-AXLE Box.

SPECIFICATION forming part of Letters Patent No. 485,219, dated November 1, 1892.

Application filed August 18, 1891.

Serial No. 403.001. (No model.)

Beit known that I, EDGAR PECKHAM, acitizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Axle Boxes and Bearings, of which the following is a specification.

My invention relates to the axle boxes and bearings for trucks used to support the bodies of street and steam railway cars.

My improvements are more especially intended for application to electricallypropelled street-cars; but their use is not restricted to such cars.

The objects of my improvements are to inwith which such ends coact so as to prevent dust or other foreign substances from reaching the same; also, to providethe axle-box with a detachable lid held firmly in place by a single nut and readily removed from the box by loosening said nut; also, to provide a simple and effective automatic lubricatder side of the axle, and thus at all times keep said axle free from dust and at the same time steadily and uniformly apply the lubricant; also, to provide means for conducting such of Vthe lubricant as be may forced along the journal toward the rear or inner end of the box back to the reservoir for the lubricant, from which reservoir the automatic lubricating device is supplied; also, to provide the axle-box with suitable bearing-surfaces, which serve to relieve the side frames of the truck from the detrimental effect of sudden shocks due to irregular movements and changes in position of the truck, and also to make such bearing-surfaces detachable from the axle-box, in order that truck-frames of various Widths may be accommodated to axlesboxes carriedM by axles of uniform lengths.

In the accompanying drawings, forming part of this specification,F`igure 1 represents a longitudinal section ot an axle-box constructed according to my invention. Fig. 2

is a front view of the joint between the axlebox and the upper part of its lid. Fig. 3 isa perspective view of said box with parts of the truck adjoining said box. Fig. 4 is an inverted view of the part of the truck-frame in immediate contact with the under side ot said box. Fig. 5 is a top View of the box. Fig. 6 is a cross-section of the axle-box, showing the axle and the automatic lubricating device. Fig. 7 is a corresponding section showing a modification of said lubricating device, and Fig. S is a side view of the lubricating device illustrated in Fig. 6.

Corresponding numerals throughout the various figures refer to corresponding parts.

9 is a car-axle, and 10 the bearing, constructed in the usual way and of brass or other suitable metal, its bearing-surface in contact with the axle being provided with a layer of antifriction metal, such as Babbit metal.

11 is the axle-box, having the inner surface of its top part resting on the upper surface of bearing l0. Said axle-box is divided into an upper and a lower compartment, 12 being a partition between the same, a large opening being left, however, in said partition for purposes lnentioned hereinafter.

13 is the lid of the box, provided at its upper end near its central part with a rib or projection 14, and from said projection the arms 15 extend laterally. j

16 is a horizontal projection extending outward beyond the lower edge of said lid, so as to fit closely a corresponding projection 17 on the face of box 10.

18 is a bolt which passes through a hole in projection 16 and through a slot in projection 17, said slot extending to the outer surface of said projection, so that as soon as nut 19 at the end of said bolt is loosened slightly, without detaching it from said bolt, lid 13 may be swung upward, the parts of arms 15 directly adjoining projection 14 in that case serving as afulcrum.

2O is a socket in the upper part of the axlebox for receiving the end of projection 14 and the arms 15, attached thereto. Said arms are free to move within said socket when the lid is in an elevated position, and maybe withdrawn from the socket altogether when the lid has been swung upward sufficiently to place projection 16 above said socket but when the lid is closed they extend downward and outward (see Figs. 1 and 2) and engage with the walls of said socket, so as to make any outward movement of the upper part of the lid impossible prior to the loosening of bolt 18 and the swinging upward of lid 13. The edges of the lid and the corresponding edges of the axle-box are either itted together, so as to produce a dust-tight joint between their metallic surfaces, or a suitable packing made of leather, rubber, or other proper elastic substance, may be placed between such" edges.

Bearing 10 is prevented from moving inward along the axle by the upper part of a shoulder 2l, which shoulder extends around the interior part of the axle-box, and from i moving outward along said axle by a fork or yoke 22, closely fitting the recessed neck 23 near the outer end of the axle, said fork being made to move in vertical notches provided in the side walls of the axle-box and 1 capable of being withdrawn altogether from said notches and from said axle-box after lid 13 has been detached from the saine.

24 is an annular projection on the rear end of the axle-box concentric with axle 9, so as j to leave an annular space between said projection and said axle.

terposed between the same.

one piece in ring form, preferably made of vulcanized fiber.

As any dust in order to enter 'the axle-box through its inner end would have -to pass two annular packings and an v'air-'tight annular space between the same, this construction ef'- fectually guards against dust reaching the 'axle-bearings from that direction.

The lower compartment in the interior-ot' the axle-box is particularly intended 'to receive and hold a sufficient quantity lof oil for lubricating the bearing-surfaces o'f the axle. 'In order to apply such oil gradually and luniform'ly to said bearing-surfaces, I provide ka 'continuous wick which reaches down intosnch `oil-receptacle, and at the same'timeis'held in close contact with the under side of the axle directly underneath the axle-bearing. In the construction illustrated in Figs. 6 and 7 I show vulcanized fiber, and a ring 29, made of 'fel-ting or other suitable substance capable Aof arresting and absorbinglubricating-oil, and in- The annular i space between yprojection-s 24 and 27 contains anotherdust-tight packing'30, constructedof j.

A suitable shoulder on. axle-box 1l serves to confine it in its position. l

V-shaped frames for supporting such wick. In'IFig. 6, 3l represents the arms of such frame, extending upward in close proximity to the axle. The arms on the sides of the axles are connected by longitudinal rods 32, as shown, and all the arms 31 are hinged together by means of a rod 33, running parallel with rods 32 near the bottom of the oil-reservoir. 34 is the continuous wick, which is stretched outside of the framework and in close contact with the under side oi' the axle, arms 31 being so shaped and proportioned that said wick will also be held against and will be supported by the inner edges of horizontal partition l2. lf dust should have reached the interior of the axlebox, such wick will as the axle revolves remove it from that part of the axle which engages with the axle-bearing above it. In Fig. 7 I have substituteda V-shaped spring 35 for the framework serving to support the endless wick, kas described above, the operation of the two devices being substantially the same.

As the revolving motion of the axle is apt to cause lubricating-oil to flow inwardly toward packing-rings 28 and 29, it is desirable to be able after ring 29 has become saturated to reconduct any surplus oil from the same into the main oil-receptacle in the axle-box. This I accomplish by providinga small conduit 36, which lea-ds from the lowest part of packing-ring 29 into such oil-receptacle, peneg trating forsuch purpose the upper part of the 25 is the outer part of the hub of the wheel, and is provided with two

annular projections

26 and 27, extending from the same outward f' The annular space be- Ytween axle 9,

projections

24 and 26, and shoulj der 21 contains a dust-tight packing constructed of two rings 28, made, preferably, of

wall of such receptacle and the adjoining packing-ring 28, as shown. j

37 is a bearing-piece placed Yon -top of the axle-box in va suitable re'cess'provided on the same for that purpose. such bearing-piece is curved in the form of a part of a sphere, and a bearing-piece 38, intended to be secured toor carried by any suitable part yof the truck-frame, is provided with a corresponding bearing-surface. The upper part'of piece 38 is furnished with aztlange containing a 'hole 39, through which a bolt may be inserted for connecting bearing-piece 38 with the main truck-frame. The ball-joint so formed by bearing-pieces 37 and 38 permits lof the axle (and with it bearing 10, box 11,'a'nd bearing 37) rapidly'ass'uining varying positions 'and inclinations, as will be particularly-produced'on curves and because of roughness o'f the track, without thereby producing sudden and injurious strains upon the vmain body of the truck. It will also be seen that as the location of the indentation inbearing-piece 37 may be varied by placing it farther out'- ward vor farther inward, and these bearingpieces are detachable and interchangeable, axles of a given length lnay thus be made to support truck-frames of varying widths. Of course the projecting part of the ball-joint could be located on bearing-piece 37 andthe receding part on bearing-piece 38, and instead of the spherical curvature of the bearing-surfaces other suitable forms might be adopted IOO rlhe upper surface of Y IIO for the same-as, for example, a cylindrical form-without departing from the spirit of my invention. The cylindrical form would permit of link-like motion and the spherical form a radial motion.

40 is an elastic bolster placed between bearing-piece 37 and the top of the axle-box for the purpose of counteracting the injurious effects produced upon the joint above the same and upon the truck-frame by sudden changes in the position of the axle-box, as mentioned above.

41 is the vertical member of a device to be interposed between the under side of the axlebox and parts of the truck-frame, The same has at the upper end of its central flat section a cylindrical projection 42, which is intended to loosely t a rounding recess 43 in the under side of the axlebox, the outer forked arms 44 of device 4l being provided with bolt-holes, whereby it is made possible to attach between or to the said forked arms the proper parts of the truck-frame, and to thus provide a further yielding connection between the axle-box and said frame. The form of the projection 42 and recess 43 may vary, according to circumstances. It is not essential that they should be of the exact conformation shown herein.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isf- 1. The combination, with the axle-box provided with a slotted horizontal projection on its surface near the bottom,of a lid provided witha hookingdevice at its upper end adapted to engage with the axle-box and with a perforated projection at its lower end and cooperating with the projection on the axlebox, and means for fastening said projections together, substantially as set forth.
