B. D. STEVENS, OF LAWRENCE, MASSACHUSETTS, ASSIGNOR TO HIMSELF,

SAMUEL (l. CROMBIE, AND G. S. APLETON.

EMPRCVEMENTIN SELF-OILING JOURNAL BOXES AND BEARINGS.

Specification forming part of Letters Patent No. 39,018, dated June 23, 1863.

To all whom it may concern Be it known that I, B. D. STEVENS, formerly of Burlington, in the county of Chittenden, in the State of Vermont, but now of Lawrence, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Self-Oiling Journal-Boxes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and in whichf Figure l represents a side view of a journal-box with my improvements applied there to. Fig. 2 represents a plan or top view of the same. Fig. 3 represents alongitudinal section on C D, Fig. 2. Fig. 4 represents a view ofthe cap B turned over. Fig. 5 represents a top or plan view ofthe parts C and D with the cap B removed; and Fig. 6 represents a cross-section on line A B, Fig. 2.

In Figs. 1, 2, and 3 the shalt A is shown in place, but not in the remaining figures.

llIy journalbox is composed of three partsviz., B, C, and D. The shaft or journal A rests and turns upon D as a bearing, while the latter has flanges D', which fit-into corresponding depressions in the part G and keep it in position. The ends of B and (l are turned out a little larger than the shaft. as indicated in the drawings, while the cap B is grooved out still more a short distance from each end, as seen at B B.

The operation is as follows: The oil being turned into the concave F of the cap B descends through the hole e down upon the ring c on the shaft A, thence down through the opening f in the bearing part D into the chamber E of the part 0, from whence it is gradually raised by the ring a., which revolves with` the shaft A, and thrown against the concave b in the cap B, from which it drops upon the shaft and is forced into theinclined grooves b' b in the cap B, and thereby caused to flow or work out laterally at the ends of the bearing D, and then drops or runs down in the spaces C G into the chamber E, to be operated upon by the ring a.

This journal-box is simple in construction, but effective in operation.

Having described my improved self-oiling journal box or bearing, .what I claim as` my invention, and desire to secure by Letters Patv 1. The combination of the ring c with the opening f and chamber E, substantially as and for the purposes stated.

2. The combination, with the parts B, C, and D, of a ring, a, or its equivalent, upon the journal, substantially as and for the purposes stated.

B. D. STEVENS.
