` points where it Iis most needed, without waste,

The following is a description of our invention, reference being had to the accompanying drawings.

Figure 1 is a top viewof our device. Fig. 2 is an end view of thesame. Fig. 3 is au inside'view of the lower half of the box', and Fig. 4 isA au, inside View o t' the upper h'alf ot' the same. 'l

A A are the flanges; 13 the oil-box, and Cv C the bearing.- 1) is a chamber constructed insideof the upper halt' of the box, aud'com- --1nuuicates with theoil-box B by'ineaus ofthe pipes b b; and'D is a chamber constructed in-. side of the lower half ol' the box. These chamf bers communicate with the jonrnalj` and bearing by means ofthe openings H and S S.' M

ll/ l and NV N are grooves iu the bearing cut in the sides of the lower' halfof the box, 'and K. :K .is a similar groove cut iu the upper half. ,'.ll1 e groove K K communicates'di'rectly with the o/il-box B: by means of the pipes a a. The groove M M communicates with-the chamber D b'y means 'of 4the holes IS S5S-S,'and the groove N N by means ofthe opening H. The chamber D connects with the chamber D when the two parts orf, the.` boltV arejoined-to- LA, portion .ofthe'oil-'f-rom the box Bis oar- -ried bythe pipes a a directly to the journal,l

audisdistributed, by.v means of ythe groove'K K, over its 'entire length. The rest of the oil -4 from the box Benterslthe upper chamber, D', through the pipes'hband lls both chambers.

pipes 'a a, and, by its motion, creates a suc.

tion throughv the holes'S S. By this means the bil which is in the lower cl1amber,-D,'is

drawn through the holes S S, and, by means of the'groove M M, is brought" into contact with the entire length of the journal.

In the. groove -N N thereis an opening/H, vwhichopens downward into theflower chamber, D. The upper edge of the groove N N, whichv is formed. by the lower edge ofthe upper half ofthe box, ismade sharp, and in--snch a manner as to scrape vthe oil from the journal .as it revolves. rlhis oii'then collects in the `'groove N N, and passes through the opening -l .into the lower chamber, VD, whence-it is drawnin the direction of the arrows, as shown in Fig. 2, to theqvacuurn at S S created by the revolution of the journal.'

' The journal is thus constantly snppliedrwith l oil, which, by means of the grooves, is equally istributed,.and the surplus oil, which wou l otherwise Work out at the ends of the b ea. ings,.pas ses through the opening H and is used again. f

We vclaimas our invention-'- l. The'combination, in journal-boxes of rotary steam'egines and pumps,.of the chambers D and D with the pipes b b, the opening H, and the holes S S, substantially as and for the purposes' hereinbefore described. f

2. The grooves K'K, M M, and NN, the, l pipes a a, lthe opening H, and" theholes S S,

when the several .parts are combined in .journal-boxes of rotary steam engines and pumps,

in the manner and for the purposes substantially as specified.
