FF1EL PHILIP DUFFY, OF WEST DULUTH, MINNESOTA.

J OURNAL-BOX BEARING.

To all whom it may concern:

Be it known that I, PHILIP DUFFY, a citizen of the United States, residing at West Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Journal-Box Bearings, of which the following is a specification.

This invention relates to improvements in journal boxes, and it is the principal object of the invention to provide a novel form of bearing therefor formed of fibrous material and being capable of withstanding material wear and also reducing friction to a minimum, thus preventing the overheating of the parts or the damaging of the shaft received therein.

Another and equally important object of the invention is to provide a bearing having means for distributing lubricant to the entire surface of the shaft.

The improvements in the details and arrangement of parts will be apparent from Fig. 3 is a vertical longitudinal section through the same,

Fig. 4: is a vertical transverse section therethrough, and

' Fig. 5 is a detail in perspective of one of the fiber bearing elements.

Having more particular reference to the drawings, in connection with which like reference characters will designate corresponding parts throughout the several views, the improved journal box includes a substantially cylindrical shell or housing formed of metal sections 1 and 2 respectively, which sections have inwardly pro ecting stop lugs 3 formed on one end thereof While the remaining ends are flanged and receive screws 4 in suitable screw threaded openings formed therein. Cups 5 and 6 are formed upon the upper ortion of the section 1 and have openings ormed in the bottoms thereof which openings communicate with longitu- Specification of Letters Patent.

dinally and transversely extending Ways 7 and 8 formed in the inner face of said section, while a seat 9 is formed intermediate said cups 5 and 6 and serves to receive the upper hanger screw therein. A similar seat 10 is formed on the lower portion of the section 2 and serves to receive the lower hanger screw therein. The section 2 is provided with longitudinally and transversely disposed ways 11 and 12, which as will be noted, receive lubricant from the upper section, inasmuch as the transverse ways 12 aline with the adjacent ends of the transverse ways' 8. Extending inwardly respectively from the confronting edges of the members 1 and 2 are supporting ribs 16 and 17.

Seated on the inner surfaces of the sections 1 and 2 and bearing on the ribs 16 and 17 are semi-cylindrical fiber bearings 13 and 14, said bearings being formed with a plurality of perforations, generally indicated by the numeral 15, which perforations COl'l'lll'lllIllCiltG with the lubricant distributing Ways 7, 8, 11 and 12, and consequently, allow lubricant to be applied over the entire bearing surfaces of the elements 13 and 14, hence, reducing friction to minimum. 7

It is to be noted that the semi-cylindrical bearing elements 13 and 14 bear at one end against the inwardly extending stop lugs 3,

while the other ends are engaged by theheads of overhanging screws 4, thus serving to positively prevent longitudinal displacement.

From the foregoing, it will be readily understood by persons skilled in the art that I have provided an exceedingly efiicient and simple form of bearing which may be used in connection with various forms of journal boxes, and with journal boxes employed for difierent forms of shafts. By the use of a fiber lined journal box, that is, by the use of the bearing elements 13 and 14 instead of babbitt,.brass or other similar metal commonly used heretofore, I not only provide a bearing affording less friction and consequently preventing overheating thereof, but also a bearing which when heated will not tighten or clamp upon the shaft journaled therein and further, a bearing which can be readily removed and replaced with a new one in but a short space of time. Attention is directed to the fact that the bearing will prove very efficient when used in connection with engine crossheads or other machinery having irregular loads applied thereto and will not be distorted-due to the constant stress applied thereto.

. Manifestly, the construction shown is capable ofconsiderable modification and such modification as is within the scope of my claims, I consider Within the spirit of my invention.

I claim:

1. A journal box including coacting half shells having inwardly directed supporting ribs and coacting half bearings within the shell members and respectively engaging the ribs and held thereby from contact at their confronting edges.

2. A journal box including coacting half shells having inwardly directed longitudinal supporting ribs and inwardly directedstop lugs at one end, and coact-ing half bearings within the shell members and respectively engaging the ribs, and held by the ribs from contact at their confronting edges, and means for holding said half bearings in engagement with ,the stop lugs.

In testimony whereof I afliX my signature hereto.

PHILIP DUFFY.
