CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 500,129, dated June 27, 1893. Application filed September 27, 1892. Serial No. 447.041. (NemodeL) To all whom it may concern.-

Be it known that I, Mosns G. HUBBARD, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented a new and useful Improvement in Car-Trucks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to the construction of the pedestal and the axle journal box, and to the appliances connected with the journal box for controlling the supply of oil to the journal, preventing its escape and waste, and access of dust or other foreign matter, and, to certain details of construction and arrangement of parts, as hereinafter described and claimed, the object being to attach the journal box and springs in an improved manner and to keep the journals thoroughly well oiled, exclude dust and avoid heating and to prevent rattling of the parts. It is especially designed for use on cars and will be understood from the following description, reference being had to the accompanying drawings, in which Figure 1,is a side view of a portion of a car body or truck, showing the pedestal, journal box, 850., in side elevation. Fig. 2 is a vertical, transverse section through the journal box. Fig. 3, is an inner end view of the box and Fig. 4, a vertical section near said end, showing the quiescent washer in side elevation, and Figs. 5, 6, 7 and S, are detail views of the end-thrust key and journal bearing plate, hereinafter referred to.

A indicates one of the car or truck side sills, B the journal box and O the pedestal'for the support of said box. The pedestals are made in the open, pendent-loop form, shown in Fig. 1; that is to say, the open, upper end, has outwardly turned arms or feet a, a, .through which the pedestal is bolted to the sill, said feet beingconnected by curves at b, b, with pendent vertical portions, b, b extending to curves 0, c, and thence inward toward each other, horizontally at c,c, to down curves (1, d; they are again bent inward at e, e, and united by a straight horizontal portion a, forming the bottom of the loop. The loop, thus formed has a wide, central, stiffening rib 0 extending its entire length on its outer surface, provided with bosses 0 for the bolts which unite it to the car or truck sill, as shown. By the construction described, a strong pedestal is obtained without unnecessary weight of metal, and well adapted to the purposes for which it is designed.

It is important that the side thrust check bolt should be conveniently removable to detach the journal boxand equally important that it should be safely locked in such manner that it will not unscrew or work loose in service. square head and screw it up into a'nut resting in a suitable socket on the upper side of the upper plate, or I form a suitable boss on the said plate and tap the hole through it to fit the screw on the upper end of said checkbolt and screw the said bolt up into it. Or the said bolt may be passed down through the said upper plate and through the lower end of the pedestal and a square nut thereon under the pedestal. ment in either of these attachments, I form on the under side of the pedestal, a small beveled shoulder or rib, on one or more sides of the head or nut, and as the head or nut is screwed into position it snaps down past the said beveled shoulder or rib, and-is held there .by the slightly elastic downward pressure of the pedestal. Thebevel ofthe said shoulderor rib is necessary to permit the head or nut to be turned backward to remove the said side thrust check bolt when it is desired to detach thev journal box or pedestal.

The journal box, indicated at B, is made in the form substantially as shown in Figs. 2, 3 and 4, having an upper, or journal compartment, an oil reservoir beneath said compartment and an inner end extension in the form of a hood, at B the flooring partition 13 separating the journal compartment from the oil reservoir, being provided with asmall trough B having a perforation. b through which any surplus of oil passes to the oil chamber below. The journal compartment and oil receptacle terminate at their inner end, in a vertical wall 19 perforated to admit the end of the journal and a pendent wall 12 at the inner end of the hood extension is also perforated, for a like purpose, the per- Therefore I construct it with a To make a safe arrangeclineson the washer E, to wipe the oil outformed onit, through which and corresponding rest in contact with the sides of the hood and end play of the journal and of the key in the E conforming in internal diameter to the form, witha fiatupper surface at f and wing plate. The lug g has a shoulder 9 formed.

one side of the bolt-head rests, the bolt being is prevented from backing off or becoming forations being slightly elongated above the axle asshown at b, to allow for wear of the bearing plate.

Within the hood portion B is arranged what I term a quiescent washer E, which is held pressed snugly against the wall 12 or aninterposed leather washer E, by a coiled' spring E surrounding the axle D. The washer E, is made preferably to conform to the shape of the hood B arching on top and standing, with its top and vertical sides removed slightly from the hood, the sides near the bottom havingprojectinglips e e, which hold the washer quiescent.

The washer is provided with a hub orslee ve diameter of the journal, and projecting on both sides of the washer plate. The .ends of the sleeve or hub arescalloped or notched, forming curves, or double inclines, e or c which serve to wipe the shaft and crowd the. oil on'the one side, outward toward the end of the journal and preventing its escape; and on the other side pushing foreign matter inward, away from the washer and journal. The hood B being open at the bottom, dust and other foreign matter wiped oh? by the inclines e will be free to drop out to the ground. a

F, Figs. 6 and 7, indicates the journal bearing plate, conforming on its lower, concave face to the journal resting therein. The upper surface of these bearing plates maybe made flat, but to save unnecessary weight of material, are made preferably arching, in

extensions thereof at f, f as shown, the part f 2 overlyingthe washer sleeve, being cut away on its rear edge as shown for like purpose. The lower edges of this plate are formed with a seriesof inclines f sloping upward outwardly and serving like the inward on the shaft, toward the end-thrust key. By the construction of the bearing plate and box, as described, the wedge-plate ordinarily used over the journal bearing plate can be dispensed with. I

The outer ends of the sidewallsof thejjonrnal box proper are cut away on an incline to receive an arched cap plate G, having on its upper end a cam-shaped hook or lip g, which engages a notch or rib l), on the outer end of the upper Wall or root of the box. The lower end of this cap plate has a perforated ear, 9',

ear 9*, on theouter end of the box,a bolth, is; passed for securing the lower end" of the cap;

on one side ofthefbolt hole,against which,

thereby prevented from turning. The nutis. screwed down on the upper end of the bolt and loose by its own gravity. The cap plateis made concave on its inner face, over the end of the axle, and faced with athin packing sheet G, which may press on the end-thrustkey H and act to hold it in place and prevent it from rattling, but, preferablya small spring h is applied to the inner face of the cap plate for this purpose The shape of this end-thrust key is shown in Figs. 5 and 8; At its outer edge, on its sides it is made in thickness to conform to the distance between parallel flanges 7:, i, on the sidewalls of the box, with which it engages, its fork engaging the groove in the axle being of a thickness conforming to said groove. "This construction prevents box.

On the sides of theboxlare formed seats at B, B, for the car springsJ, J, resting thereon, as shown in Fig. 1. These seats are provided underneath, with stiffeningribs j, of the double-bracket form, shown, which give great rigidity and strength" without unnecessary weight of material.

Spring seat cap-plates K, are secured by vertical ears k, to the car sills .A, directlyover the .boxes, and between these and the box seats B springs J are .secu.red,one or :more on each side of the "box, side thrust bolts Z, l, passing through the plates K,and springs, through oblong holes in the-spring seats B, which allow a limited lateral movementof said seats and through the-horizontal portions c, c'., of the pedestal, as shown. These [bolts allow the box to rise and fall freely wlrile leaving the weight of the-car supported :by the springs and serve .at the same time to strengthen the pedestal and to'gu-ideand limit the movement of thejournal box.

The pedestal is provided directly underneath the journal box with asocket at m,.in which a rubber spring "m' is secured to relieve jar orsudden concussion, and the spring cap plates K are inlike manner ;provided, on their lower faces, with sockets '11, containing projecting springs '11.. These springs may,if

desired, be secured to the lower-and upper faces of the journal box, with the same result of relieving the car from sudden concussion.

The partition flooring between thejournalbox and oil compartments, isperforated toreceive a wick W applied to convey oil to the journal in the usual manner.

Rocker plates 19, p, are interposed at the ends of the springs J, J, between thespring seats B andthe springs, andalso between the springs-and cap plates K, similar in construction .tothose described in my patentdated January 5, 1 892, numbered 466,349.

From the foregoing description 'it will be :seen that when the eerie moving in either=direction, the oil will ,be conveyed up to the journal by the wick conductor, and bythe op- :eration of the inclinesion thelower edges of the jounnal bearing,-all-of the oil whichiis not lcarried under the journal bearing will be lpushed along toward -the outer end of the journal and deposited on the end-thrust key to keep it thoroughly lubricated, so it will neither wear nor rattle; any surplus oil will drop down into the small trough under the said end-thrust key and pass through the oil hole at the center of said trough and thus keep up a constant circulation of oil while the car is in motion. This action of the inclines on the lower edges of the journal bearing also tends to keep all oil from working along the journal toward the inner end thereof and this arrangement, together with the quiescent washer pressed uniformly against the inner end of the journal box, and the cams or inclines on the end of the hub of said washer, projecting into the journal box, effectually prevent all escape of oil from the inner end of the journal box.

Having thus described my invention, I claim as new 1.
