JOURNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 261,274, dated July 18, 1882.

Application ,filed June Y5,1882.' (No model.)

To all whom it may concern:

Be it known that I, FREDERICK H. SWEET, of Williamsport, in the county of Lycoming and State of Pennsylvania, haveinvented certain new and useful Improvements in Journal- Boxes, of which improvements the following is a specification. Y

My invention relates to journal-boxes of the class having a cap composed of two sections which are independently adjustable toward and from the center of the shaft; and its object is to afford improved facilities for the adjustment ofthe Cap-sections, to provide a convenient reservoir for lubricating material, and to reduce as far as may be the height of the Complete box.

To these ends my improvements consist in certain novel devices and combinations, embracing a fixed box having a central journalrecess and a segmentalV guide on each side thereof, two adjustable Cap-sections fitting on the guides and adapted to bear at their adjacent ends against the journal, adj ustingscrews bearing against the outer ends of the cap-sections, a lip or dust-guard formed upon one of the sections and fitting over the other, and an internal oil-reservoir covered by the guides and journal, all as hereinafter more fully set forth.

In the accompanying drawings, Figure l is a plan or top view of a journal-box embodying my invention with one of the cap-sections removed, and Fig.2 a transverse section through the same.

To carry out my invention I provide a box or bearing, A, which is secured in desired position upon the frame of a machine by bolts a, and has a central recess, a', fitted to receive and support thejournal A of a shaft. A segmental guide or support, a2, is formed upon thc top ofthe box A, on each side of the central recess, and a cap-section, B, the lower face of which corresponds in curvature with the guide, is fitted upon each of said guides and adjustably secured thereto by a cap-bolt, b', passing through aV slotted hole in the capsection. The adjacent ends of the cap-sections are adapted to bear'against the periphery of thejournal, above the axis thereof, and in the instance shown are recessed segmentally to a corresponding radius. A lip or dustguard, b2, formed upon the inner end of one ot' 4the cap-sections fitsneatly over the outside of the box, and is closed at top by the guides a2,VV

and by thejournal A', which protrudes into it through a longitudinal slot in the central bearing-recess.

Oil may he introduced to the reservoir through one of the openings in which the cap-bolts fit, or a special oil-hole may be provided. Y

It will be seen that my improvements enable a material reduction in the height of the journal-box to be effected as compared with sectional cap-boxes having inclined bearingsurfaces, as heretofore employed, and thus adapt the box to use in positions where the latter construction Would be impracticable. A

ready and convenient adjustment of the capsections is also afforded and efficient lubrication assured by the'provision of the oilreser.
