KNOW ALL 'MEN BY THESE PRESENTS:

That I, ISAAC D. MATHEWS, of the city and county Aof Worcester, and Commonwealth of Massachusetts, have invented certain new and useful Improvements in .Iournal-Boxesgxand I do hereby declare that the followingis -a full, clear, .and exact description of the sanne,` reference being had to the accompanying drawings, forming a. part of this specification, in which` Figure, 1 represents n perspective view of one-cf my improved journal-boxes, as it appears when applied to use; and v Figure '2 represents a vertical central section of the box and shaft.

To enable those skilled in the art to which myinvention belongs to malte and use the same, I will proceed to describe it more in detail. l Y i In the drawings, A is the hanger, having' two projections, Bl and C, in which are the adjustingbolts D E, which help to support and retain the outer shell F of the journal-box G in place. Within the shell F is an inner box, I, the lower half, J, of which has a rounded projection, a, which rests and turns in a concavity, 6, in the bottom, K, ofthe shell F. The latter has a. projection, c, which enters a recess, eZ, in the part a. The upper half, L, of the inner box I is retained in proper position by the cap M, which ts over the rounded projection, e, of the part L. Two oil-holes, ff, are made in the part L, while the two pointed projections, gg, upon the undersides of the two end caps, F F', of the shell F, point directly into the tops of the oil-holes ff. The shaft N may be turned down to receive the inner box I, as shown in the drawings, if preferred. Bevelled collars, O O, are placed upon'the shaftwithin the shell F, asshown in the drawings.` Wires or pieces of metal, l 1or other suitable material, are fastened to the collars O O, so' as to project into the space between the box I and shell F, as indicated in the drawings. y

v The operation is as follows: A quantityof o'il or lubricating substance isturned into the shell F, which runs into the bottom ofthe Shell F, from which it is brought up by the ends ofthe wires l 1, and as these wires strike against the points g g, the oil or lubricating substance is scraped off, and drops from 4the points g g into thev holes and passes down to lubricate the bearing partslof the shaft and box. The collars O O prevent the oil'from running outupon ythe shaft beyond the shell F. The-collars O O may be made with a shell to extend up over the ends ofthe box I, to take up and throw the oil upon the points g g, or drop it into the holes ff. The edges of the collars O O, when thus extended, may have bristles or some fibrous substance or small yielding wire points attached thereto to deliver the oil to the pinsg g. The wires 1 1 are made so as to draw against the points g g, whereby the'oil is scraped off. This is effected by inclining their ends2 2, back of the` pointsof their. attachment to the collars O O. i

It will be seen that the box I can turn `i'reely to conform tothe positions ofthe shaft as it revolves, wherebyl all binding of the parts is obviated. The shell part F is bolted tothe hanger A, the bolt being passed through a slot in the hanger, lso that the s'hell can be set up or down. The shell may be applied to a stationary bo-x or bearing with goed results, the shaft being provided with the collars and oiling-npparatus, substantially as above described. The invention is equally applicable to shafts which have no bearings turned down, as shown in the drawings.. m m are caps, which cover the oil-holes it n, to prevent the entrance of dust and dirt.

Having described my improved journal-box or bearing, what I claim therein as new and of my invention, and desire to sceureby Letters Patent, is-

1. The combination, with the inner box I, of the shell F, substantiallyas and for the purposes set forth.

2.. The combination, with the shell F and the points'or projections g g, ofthe collars O-O and oilers 1 I, substantially as and for the purposes set forth.

S, The combination, with the bearing or journal-box of ashaft, of one or more collars O and Oilers' 1, substantially as and for the purposesset forth.

4. The combination of the points g g with the caps F4 F and the top part, L, of thebox I, substantially as and'for the purposes sot forth. l

5. The combination of the Oilers 1 l with the'collars 4O O, as described, whereby they draw against the points or projections g y, which scrape thev oil from the oilers, as set forth.

6. The combination of the shell F ande-aps F F with the collars O O and oilers 1 l and shaft N, substantially as and for the purposes set forth. ISAACV D. MATHEWS.
