SPECIFICATION `forming part of Letters Patent No. 392,845, dated November 13, 188.

Application filed June 25, ISSS. Serial No. 278,073. (No model.)

To all whom, it may concern:

Beit known that I, HORACE G. BIRD, a citi zen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Journal-Boxes, of which the following is a specification.

My invention relates particularly to improvement in the class of j ournal-boxes in which the lower portion forming the oil-re ceptacle is adjustable upon and separable from the upper portion.

rihe objects of my improvement are principally to provide a construction ofjournal-box for use especially on street-cars which shall permit thorough cleansing of its interior readily and without inconvenience and permit ready access to the oil-feeders and springs for holding them in position; to provide more effective means than have hitherto been provided for shielding the interior of the box against the ingress of injurious matter-such as dust and einders; to provide an improved construction of bearing or brass,as it is termed, whereby it shall afford a stop against longitudinal movement of the journal and which shall be readily removable and as readily adjustable in its position, and to provide a generally improved construction ofjournalbox.

In the drawings, Figure lis an end elevation of my improved journalbox shown as applied to a car; Fig. 2, a partlybroken transverse section of thesame, Fig.3,asection taken on the line 3 3 of Fig. l and viewed in the direction of the arrows; and Fig. 4, a section taken on the line 4 4 of Fig. l and viewed in the direction of the arrows.

A, Fig. l, denotes the bott-om sill of a car, from which extend downward the parallel vertical bolts o' and r through opposite ends of the bent brace q and through the adjacent ends of the braces q', nuts q2 being provided on the lower projecting ends of the bolts for the usual purpose, and sleeves or hollow columns p surround the -bolts and are confined between the under side of a plate, m, on the carsill and the braces g', as shown.

B is thejournal-box, formed without an integral bottom and provided with lateral sockets o, through which the bolts r and columns p extend, and confined between the sockets o and plate c are spiral Springs u, surrounding the columns.

The construction, as thus described, except as to the bottomless portion of the journalbox, involves no features of especial novelty, but resembles that in common use with journal-boxes of old construction.

The journal-box B is formed in two sec tions, C and C, the former being like or substantially like any ordinary journal-box, except that it has no bottom, while the latter is in the form of a coverless receptacle, the sides of which fit inside those of the part C, as shown, one end being provided in its upper edge with a semicircular recess to form,with the circular portion of the opening in the cor responding end of the part C, the circular opening through which the journal D enters the box, and the part C is provided with lateral flanges or ears m, extending from its base portion, and with seats 11i/,which abut against the lower edges of the part C, extending the full length of the latter. Ihe ears m are perforated and receive the threaded ends 0f a U- shaped bolt, Z, which passes transversely over the part C near its center, the projecting ends of the bolt being provided with nuts Z', which serve to fasten the bolt in place and to secure the part C tothe part C.

Between the inner end of the part C of the sectional j ournal-box and the adjacent end of the part C or receptacle for the lubricating material is a recess, la, to receive a ring, E, preferably offelt, surrounding the journal and serving as the outer shield against the ingress of dust and other objectionable matter to the interior of the box, and besides the shield E, I also provide an inner shield, E, like it, and confined in a recess, z', in the part C, and a space, i', between one inner side of the part C and a partition, h, extending from the base thereof.

Though it is not new to providea shield, E, for the purpose named, a single barrier of the kind is found to be inadequate for the purpose for which it is intended, while the double barrier affords effectual protection against the access of dust and the like to the journal.

rIhe inner surface of the upper side of the part C is recessed, as shown at g, and an opening, s, controlled by a screw-plug, s', leads into the recess and affords a duct for oiling the ico brass, hereinafter described, and to which the recess g leads, as shown, and at opposite ends of the recess g are offsets g and g2, between which the bearing or brass F tits, and is confined against longitudinal movement, while lateral movement thereof is prevented by its confinement between lugs f, provided on the inner sides of the part C.

The brass F, which is hollowed out longitudinally on itsA upper side, as shown, is recessed on its under side near its forward end, as shown at e, the recess fitting over the collar e on the endof the journal when the box is in position, whereby a stop is provided to prevent longitudinal play ofthejournal, which would tend to produce wear thereon and permit the introduction of dust and the like past the inner shield, E', into the journal-box.

G G are the lubricating-strips, composed, preferably, of stiff fibrous material in flat strips held together by opposing springs, d, extending against them from opposite corners of the base or side of the part C.

The strips G are spread apart along their upper edges by the insertion between them of the journal D, and serve to carry to the latter, by capillary attraction, thelubricant contained in the receptacle C.

rlhe outer end of the journal-box is provided with a hole, c, through which access is gained to the interior, and which is provided with a removable cover, c.

To clean the box or gain access to the interior thereof for any of the purposes stated, the brace q is first removed by loosening one nut, g2, and turning the brace on its other fastened end, and then the nuts Z are loosened, permitting removal of the part C, which contains the supply of lubricating material of which the box is to be cleansed, and after cleansing the part is readjusted in its position and secured by applying the nuts, when the brace q is again secured in place. To remove the brass F, the box B is pried to raise the shoulder or offset g2 from engagement with the head of the brass,'when the latter may be withdrawn through the opening c, the cover c' being previously removed, thus obviating the necessity of raising the car, as required with all other journal-boxes, and the insertion of a new brass is effected by introducing it into position through the opening c with the box raised, as described, by prying.

What I claim as new, and desire to secure by Letters Patent, is-

1.. A sectional journal-box, B, comprising, in combination, a bottomless part, G, and a part, O, in the form of a coverless receptacle inserted into the part C, and provided with perforated ears m, extending laterally fromits base portion,and with seats m', abutting against thelower edge ofthepart C, a U-shaped bolt, Z, straddling the part C and extending at its ends through the ears m and nuts Zon the ends of the bolt, substantially as described.

2. In a sectional journatbox, the combination of a bottomless part, C, having recesses 7c and fr' near the opening, through which the journal is admitted, a part, G', in the form of a receptacle, removably secured to the part G, and forming the base thereof, a partition, h, extending upward from the bottom of the part G', and shields E and E', confined in the said recesses and. to surround the journal, substantially as and for the purpose set forth.

3. In combination, a journal-box having an opening, c, and provided internally with a recess, g, having a controllable oil-duct, s, and with offsets g and g2 and lugs j", a journal, D, having a collar, e', near its end, and a brass, F, hollowed on its upper side and fitting between .thc said offsets and provided on its under side near the outer end with a recess, c, fitting over the collar c', substantially as and for the purpose set forth.

4,. A sectional journal-box comprising, in combination, a bottomless part, C, having re cesses 7u and /inear the opening through which the journal is admitted, a brass, F, confined against play in the part C and affording a stop to longitudinal movement of thejournal, a part, C', in the form of a receptacle removably secured to the part C and forming the base thereof, a partition extending upward from the bottom of the part C', annular shields E and E', confined in the recesses lr and@l and to surround the journal, and a covered opening, c, in the box, substantially as described.
