SPECIFICATION forming part of Letters Patent No. 391,4.66, dated October 23, 1888.

Application filed M'ay 5, 1886. Serial No. 201,213. (No model.)

T 0 all whom it may concern- Be it known that I, GEORGE F. GODLEY, 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 Oar-Axle Boxes, of which the following is a specification, reference being had therein to the accompanying drawings, wherein- Figure l is a sectional elevation, showing axle-box, brass or hearing, axle, and cross bar for receiving end-thrust of axle, embodying my improvements. Fig. 2 is a plan of bearing-surface of the brass. Fig. 3 is a sectional view similar to Fig. 1, showing brass and crossbar for receiving end-thrust of axle, formed in one piece. Fig. 4. is a side elevation of axle-box, showing sliding lid. Fig. 5 is a perspective showing part of axle-journal and of cross-bar, with lining or packing for receiving the end-thrust of the axle. Fig. 6 is a section on line 1 1, Fig. 4-. Fig. 7 is a perspective of brass and of axle journal partly broken away, and Fig. 8 is a sectional view of a modified form of cross-bar for receiving end thrust of axle.

My invention has relation to caraxle boxes in general, but more particularly to that form of same having sliding lids, dustshields with spring pressure devices, and bearings or brasses having a selflubricating lining or packing; and it has for its object simplicity and durability of construction of parts,whereby they are easily accessible for repairs or for other purposes, dirt or dust is effectually excluded from the box, and the heating of the axle-journal in its brass or hearing or as it impinges against the brass or the cross-bar for receiving its end-thrust is avoided.

My invention accordingly consists of the combination, construction, and arrangement of parts, as hereinafter described and claimed, having reference particularly to a brass or bearing having on its under or bearing surface depending side and edge flanges, diagonallycrossing ribs extending from corner to corner of said bearing'surface, and intermediate ribs connecting said diagonally-crossing ribs to the middle parts of the side and end flanges to form a cluster of separate cells or chambers for the reception of a filling or packing of selflubricating material; to a brass or bearing having a lip or lug on its front end for engagement with a cross or end-thrust bar for the axle to keep said bar from rising vertically; to the combination therewith of a cross-bar having a similar lining for receiving the end thrust of the axle Without generating friction or heat between the end of axle and'eross-bar; to a hearing or brass having in its ends a filling or packing to avoid heating-the collars or shoulders of the axle as it makes an eud-thrust, and to a dust-shie1d having permanently attached to its front side spring-acting or pressure devices arranged to press the shield against the inner side of the rear end of the box to close or seal the axle-opening therein.

In the drawings, A represents an axle-box,

of any suitable or desired construction, having a front or lid opening, a, lid ct, brass or bearing B, and a chamber, 0, in its rear end; or the latter has double walls 0 c, if desired,with usual opening, 0, for axle D. The journal d of the latter may be without a front end collar, or plain, as illustrated in Figs. 1 and 3, or it may be made in the well-known manner, as partly indicated in Fig. 7.

The brass B is preferably formed on its under side with a series of approximately diagonally-arranged ribs, Z) and Z), connecting the ends and sides 12 and 21 respectively. The main ribs I) extend approximately from corner to corner of the brass, and the ribs b from the center of the ends and sides of the brass to the middle of one-half of the ribs b, as shown more plainly in Fig. 2, to form acentral series or cluster of rhomboidal-shaped chambers or cells, If, and an outer series of triangularshaped chambers, If, in the lower or hearing side of brass B,for the reception of a self-lubricating or other compound or material, E, for the axle'journal d. Theintermediate ribs, 1), are joined to the ribs 2) and to the edge flanges, as shown and described, to afford the requisite strength for the middle parts of said edge flanges. Any suitable self-lubricating compound having for its basis asbestos, graphite, lamp-black,0r equivalent substance combined by an indurating material is preferably used; but other suitable self-lubricating compounds in contradistinction to soft anti-friction metals may be substituted. The lining or packing-E is so placed in recesses or cells that it will project below the lower surfaces or edges of the ribs 1) and b and below the sides and ends of the brass B. as shown in Fig. 1, to prevent any part of the lower surface of the latter coming in contact with the axle -journal;' but, it desired, the lowersurfaces of said ribs and of the packing or filling may be flush, as shown in Fig. 3. A brass B so constructed self-lubricates the journal d, and by reason of the latter not coming in contact with the brass itself all danger of heating of the latter is avoided.

The cross-bar F,for receiving the end-thrust of the axle D, is placed in the usual L or other appropriate side lugs, f, (see Fig. 1;) but this bar has on its side f, next to the end of the journal d, a recess, f*, in which is apacking or lining of self-lubricating material, f, as above described, for brass B, so that as the axle makes an end-thrust against bar F and its end revolves in contact therewith the packing f" preventstheendofaxleheating. Thispacking in cross-bar F in relation to the end of the axle is more plainly shown in Fig. 5. If desired, the cross-bar recess f may be formed in a projection, 1, extending from the bar, as indicated in Fig. 8. Then the bar F is used separately from the brass B, the latter has a projecting front lip, b, at its lower edge to keep the bar F from rising out of its guide or holding lugs f.

Instead of making the brass 13 and cross-bar F in two pieces, they may be in one, as shown in Fig. 3, in which case the bar F is in the form of a lip depending from the brass, and it and the lip are held in position by the usual fastenings for the brass.

When no cross-barF is used, and when an axle-journal having a collar at its front end is employed, the ends of the brasses are cut out or recessed, as shown at b Fig. 7, and these recesses are filled with the packing or lining E for lubricating the adjacent and contiguous edges or surfaces of the front and rear axlecollars, d d respectively, during end-thrust of the axle.

Between the double wall a c,or in the end of the box A, is located a flexible or other desired form of dust shield or plate, G, having axleopening 9, and upon its forward side permanently-attached springs g,of any suitable construction, which act to press the rear side, 9', of the shieldagainst the inner side, 0 of the end of the box, as shown more plainlyin Figs. 1 and 3, to close up the axle-opening cin box A for effectually excluding dirt or dust from the same.

Any form of lid a may be used; but I prefer to loosely secure it to the box,so as to slide up and down without being removed from the box. To do this I cast lugs or ribs h on the sides a of the box adjacent to the edge of lidopening a, as shown in Fig. 4. These ribs h are wedge-shaped or taper from below upwardly,

and are embraced by an L-lug, a, formed on each side of the lid and having rounded inner side, a, for impingement with the back of the ribs h, as more plainly shown in Figs. 4 and 6, to keep the lid upon the ribs h and adapt it to easily slide thereon. The upper inner side of the ribs h is curved, as shown at h, to permit the lid as it is raised to be moved over the top ofthe box. The lugs a upon the lid are relatively so arranged that when the lid is raised or opened, as shown in dotted lines 00, Fig. 4, the upperedge of the lid strikes against the bearing-bars H of the box to prevent the lid moving off ribs 71. when raised; hence in putting the box in position beneath a car the lids are aflixed to the boxes before the bearingbars H are inserted in place upon the boxes.

If desired, the sides of the boxes may have rearwardly-projecting flanges (6", as indicated in thedotted lines,Fig. 4,01 the long side of the lugs a may be continued to the top and bot tom edges of the lid to cover the side joints between the lid and box for excluding dust therefrom. As the lid is lowered the lugs a sliding down the wedge-shaped ribs h, draw the lid to the sides or edges of axle-box opening a to form a tight joint therewith. For convenience of moving the lid it is preferably provided with a push lug or knob, a".

The diagonal arrangement of ribs Z) I) in bearing B aflords the greatest possible extent of cell space for the lining E without impairing the strength of the bearing and gives good or increased support for the lining in the cells, so that it will be less liable to cram ble or unduly wear under heavy pressure or other deteriorating causesincident to wear and tear.

The springs 9, being permanently attached to the shield G, make the latter complete in itself, and it requires no extraneous or independent devices attached to the axle-box for holding the springs and the shield in contact with the inner side of the rear wall of the box.

What I claim is- 1. A car-axle brass or bearing having on its under or bearing surface end and side flanges, diagonally-crossing ribs extending from corner to corner of said surface, short or intermediate ribs connecting the diagonally-crossing ribs with the center parts of the end and side flanges to form a cluster of cells or chambers, and a packing or filling of self-lubricating material in said cells or chambers, substantially as set forth.

2. A car-axle brass or bearing having on its under or bearing surface end and side flanges, b b, diagonally-crossing ribs 1), extending from corner to corner of said surface, \J-shaped ribs b, connecting the ribs 1) to the center parts of the flanges I) Z) to form a cluster of rhomboidal and triangular cells or chambers, and a packing orfllling of self-lubricating material in said cells, substantially as set forth.

3. In combination with an axle box and axle having inside lugs, f, a crossbar, F, located in front of the axle and supported on said lugs, and a packing or filling of self-lubricating material in said bar adjacent to the end of the axle, substantially as set forth.

4. A caraxle brass or hearing having in its ends open cells or recesses, and a lubricating filling or packing in said cells for oiling the adjacent axle-collar, substantially as set forth.

5. A car-axle brass or bearing having in its bearing surface or side cells or chambers, some of which extend out to the rear end of the axle-brass, and a lubricating filling or packing in said cells, substantially as set forth.

6. In an axle-box,the combination of a crosswith bar or lip F, having on its inner side alubricating filling or packing, f substantially as set forth.

8. In combination with a car-axle box, a dust-shield having secured on its front side permanently-attached springs for pressing the rear side of the shield against the inner side of the end of the axle-box, substantially as set forth.

9. An axle'box having rear double walls 0 a, shield G between the walls, and spring attached to the shield and located between the latter and the front wall 0, as and for the purpose set forth.

10. An axle-box brass having front lip or lug, b, in combination with separate cross-bar F, having suitable supports, f, and a packing or filling, f, substantially as set forth.

11. The combination, in a car-axle box, of a brass or hearing having a front lug or lip, b, a cross-bar, F, beneath said lip, and supports for said cross-bar, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
