JOURNAL-Box.

SPECIFICATION forming part of Letters Patent No. 269,714, dated December 26, 1882 Application filed July 17, 1882. (Model.) i i A To all 'whom it may concern:

shown in full elevation.

Be it known that I, LEVI H. RoBEn'rs, of Paris, in the county oi' Edgar and State of Illinois, have invented certain new and useful Improvements in Journal-Boxes, ot' which the following is a full, clear, and exact description.

rlhe object of this invention is to provide a practical anti-friction journal or axle box for railroad-car and other axles or shafts; Aand it consists principally ofjournaling two anti-fric tion wheels or rollers in and between two (front and rear) boxes, whichare coupled together and adaptedto receive or to be placed upon the .journal portion of the axle, with the anti-friction wheels or rollers resting upon the axle and supporting the weight ofthe car or other load.

The invention also consists of triangular oilboxes for the journals ot' the antifriction wheels or rollers, of the means for coupling the said front and rear boxes together, and of suitable journal-blocks to tit in the front. and rear boxes upon the journals of the antifriction wheels.

Reference is to be had to the accompanying drawings, forming part of this specifica-tion, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a broken elevation of the rear face ot' the rear box, showing the axle of the car in section. Fig. 2 is a broken elevation ot' the front face ot' the front box. Fig. 3 is a broken elevation of the inner face of the front box, showing the axle of the car and the outside journal of one of the anti-friction wheels in section, the outer anti-friction wheel being Fig. 4 is a transverse sectional elevation of the complete axle-box, part being broken away to show the dust plate or slides of the journals vof one of the antifriction wheels. Fig. 5 is a front elevation of one ofthe dust-plates removed fromits slot or recess in the box. Fig. 6 is a perspective view are in place in the boxes G C', or rather when these boxes are in place upon the journals ot the wheels, the wheels are held in place by the journal-blocks D D, which are placedin the boxes and lit upon the journals between the lla-tiges c and bosses c'. These journal-blocks are made preferably of brass and cast with the ribs d', are segmental in form, and are held in placein the boxes and upon thejournals b b ot' the wheels by the shelves or ledges E E and recess d", formed upon the inside of the boxes, as shown in Fig. 2.

The front and rear boxes, C C', are in all essential particulars duplicates ofeach other, except that the rear box, C', is formed vwith passages c a through the walls thereof for the passage of the axle A, while the front box, (l, is formed with the thrust box or recess E to receive or lit over the outer end ot' the axle, as shown in Fig. 4, and that the outer or rear wall of the box G is made double or formed with the passage d, as shown in Fig. 4. In this passage d is placed the dust plate or slide f, which surrounds the axle A and closes the passage a' in the rear Wall of the rear box,C, as shown, and this plate is supported by the axle which it protects, and thekpassage d is of sucl height asto permit it to move up or down with the axle. with any upward motion of the car, and the plate is of such size as to perfectly close tbe passage c at all times.

The inner Wall ofthe front box, C, and also the inner wall of the rear box, C', are made double or formed with the recessesjj andjj'.- In the recesses j j are placed the dust plates or slides g g, and in the recessesjj are placed similar dust plates or slides, g g, as sh'ownin Fig. 4. l These plates it upon the bosses c c' of the journals' of the friction-rollers B B, as

IOO

shown in Fig. 4, and close perfectly the openingsk kin the inner walls of the boxes, through which thejournals ofthe wheels B B pass, as indicated in said figure, and thus prevent altogether the entrance of dust into the oilboxes F F, in which the journals b b ot' the wheels B B run.

G G represent plates which rise diagonally from the lower side or bottom ot` the boxes U C', and form a V-shaped partition in the center ofthe boxes, as shown in Figs. 2 and 4. These plates give the oil-boxes F F triangular form, as will be understood from Fig. 2, so that the waste put in the oil-boxes will be forced nearer to and kept in contactwith the journals -b b as it sinks gradually to the bottom of the boxes.

The oil-boxes are closed by the covers H H, and these covers are formed upon the under side and near the ends with the ribs or downward projections ll, which, when the covers are in place, come in front of thejournal-blocks l) D and prevent them from getting out.ot' place, as will be understood from Figs. l and 2. The front and rear boxes, C C', are preferably coupled together by means of the upper and lower plates, K K, upper and lower outside clainp-plates, L L, end plates, M M, U- bolts N N, and cross-plates O O, as shown in Fig. 6. rlhe upper and lower plates, K K, are correspondingly guttered upon the inside, as shown at o o, to receive the lips p 1J, formed at the upper and lower edgesot' the boxes,and the side plates, M M, are also correspondingly guttercd, as shown at 0 o in Fig. 6, to receive the lips pp, formed at the outer edges of the said boxes, as shown in Figs. 1 and 2; and

Y upon the outside and at the ends of these side plates are formed the claws q q, which retain the U-bolts N N, as shown in Fig. 6.

Along the outside of the plates K K are formed the gutters q' q', in which the outside clamp plates, L L, rest, as shown in Fig. 4, which prevent all danger of lateral movement ot' the plates K K.

All ot' the parts of the journal-box having been put in place, the cross-plates 0 0 are put upon the U-bolts N N, and the nuts s s are then turned upon the threaded ends of the said bolts, and thus clamp all the parts firmly and securely together.

In Fig. 7 plain bolts NN are used in place of the U-bolts N N. When these bolts are used, instead ot' forming the end plates, M M, with the claws q q, these plates will be formed with the bolt-passages t t, through which the bolts Nl N pass, as shown in said Fig. 7.

The passagesjj and j j are made wider at the top than at the bottoni, but straight on the inner edges, as indicated in dotted lines in Fig.l 3, so that the plates will be free to move upward as the journal-blocks D D wear away, but not toward the center. The outer end of the axle A is formed with the central projectioinv, as shown in Fig. 4, which receives the side-thrust of the axle against the wall of the thrust-box E', thus greatly reducing the friction and the outer ends of the journals b b of the anti-friction wheels B B are formed with the central projections, ofv, as shown in said figure, to receive. the side-thrust against the outer walls ofthe boxes G C.

T is a truss-band placed around the outer end of thefrontbox, C, and T is asimilar band placed around the rear end of the rear box, C', as shown in Fig. 4, for reenforcing the boxes and protecting them at the outer edges.

By this construction of the axle-boxes it will be seen that the friction and journal motion in the boxes will be greatly reduced, thus increasing the capacity of the motive power and preventing all danger of boxes becoming heated. Besides, the boxes are strong and durable.

Having thus fully described my invention,I claim as new and desire to secure by Letters Patent- 1. The front and rear boxes, O C', in combination with the anti-friction wheels B B, journaled in and between them, the said boxes being coupled together, substantially as and for the purposes set forth.
