Application filed November 21,1890. Serial No. 372,216. (No model,)

To all whom it. may concern:

Be it known that I, Oscar S. Sawyer, a citizen of the United States, residing at Truxton, in the county of Cortland and State of 5 New York, have invented certain new and useful Improvements in Journal-Boxes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to io whichjtappertainstomakeandusethe same.

My invention relates to journal-boxes; and the object of my invention is to provide an anti-friction journal-box. I attain said object by a certain construction and arrange15 ment of parts fully described in this specification, and illustrated in the accompanying drawings, in which—

Figure 1 is a detailed view, in perspective, of the journal-box detached from the hub or 20 casing. Figs. '2 and 3 represent the box inclosed in the casing or hub, respectively. Fig. 4 is a longitudinal sectional view of one of the rollers used in the construction of my journal-box. Fig. 5 is a similar view of a 25 modification. Fig. 6 is a plan view of one of the collars broken away.

Referring to the drawings, the letter A designates the collars, each of which is constructed with a circular cavity a near the 30 rim upon the inner side. Each collar is provided with the threaded portions a', which lead to the cavity a, thence to the journalbearings a². Each cavity or chamber a answers the purpose of a repository for the oil 35 which lubricates the journals b. “The portion of the perforations a² next to the journals b may be filled with a soft packing, through which the oil will slowly ooze, thereby thoroughly lubricating said journals. Said per40 forations are also provided with the screws a³, which are easily removed when the cavity a needs to be filled with oil.

B and B' represent the rollers, which may be constructed as shown in Fig. 4 or Fig. 5, 45 preferably as shown in Fig. 5, with the chamber b’, the threaded orifice b³, communicating with said chamber, and the small perforations b², leading from said chamber to the outer surface. The chamber b' may be filled with oil by removing the screw b² and inserting 50 the neck of the can into the orifice b³ in the end of the journal b⁵. This provides said rollers with a supply of lubricant, which gradually oozes through the small perforations b²and keeps the journal-box thoroughly lubri- 55 cated. I attach special importance to this feature of my invention and the feature whereby the oil is supplied to the journals b, for the reason that in the event my journalbox is used upon railway-cars said chambers 60 can be filled with lubricant and run thousands of miles without again filling the same.

C indicates the braces that secure and hold the collars A in position. Said braces may be secured by being screwed or riveted through 65 the collars A, or the braces C and the collars A may be molded or constructed in one piece.

D is the casing that incloses the journalbox and the hub E.
