LUBRICATOR.`

p To all whom it may concern:

ln my improved construction the casing is simplified, the' oil cylinder is placed upright, the steam `chest is extended and improved, a direct emergency feed is added, and other modifications of structure are made.

My invention consists 'in' the novel arrangement of the various parts, as hereinafter described, particularly pointed out in the claims, and shown in' theaccompanying drawings, in which- Figure 1 is a' perspective View of my device; Fig.v 2, a vertical cross-section through the center of the oil cylinder, showing a part in elevation; and Fig. 3, a vertical longitudinal section on the line 3 3 of Fig. Q, showing the cylinder in elevation.

Similar characters ofreference refer to similar pa rts throughout the several views'.

ln the drawings, the oil cylinder M is setl' vertically upon a'bracket O, fastened on the `boiler A. 0n the top and along one side of the cylinder M, and integral therewith, is the steam chest L, into the top of which leads the steam pipe YI from the boiler A.

0n the top of the cylinder and to one side of the steam chest L is the oil cup P (Fig. 1),

whereby oil is introduced into the oil cylin- I der M On the side of theoil cylinder M oppositethe steam chest and integral therewith is the casing N, having a large lower receptacle, a vplurality of intermediate receptacles Z', and a plurality of upperreceptaclesv X'. across the up er part of the casing N so that the water, o condensed steam may be admitted under pressure into any part thereof. From the upperchambcrs X', the pipes G, G', and G2 lead toward the parts to be lubricated. From the lower chamber corresponding pipes also lead toward the parts to be lubricated, and each pair of upper and lower pipes run into the common pipes H, H', and' H2 which lead directly to the parts to be lubricated.

In the operation of the lubricator, after oil has been introduced from the steam chest to each of the The steam chest L' extends Speeication o! Letters Patent. Patentd M31. 14, 1911. Application filed December 16, 1909. Serial No. 533,368.

through the oil cup l, steam is admitted to the steam chest L through the pipe I, condenses into water, and is held under pressure by the steam pressure in the boiler. The valve J' admits the fluid under low the piston. ward and the oil passes through the passage lV into the lower chamber of the casing N. The needle valves If, F', and F2, or any of them, are opened, and oil passes up the small tubes S, S', and S2 into the intermediate chambers Z', atthe ends of each of which are pairs of bulls-cye glasses D, D','and D2, for viewing the upward passage ofthe oil. From these intermediate chambers Z' the pipes T' lead npwa'rd through the upper parts of the casing into 'the chambers X' respectively.` Condensed steam is admitted pi es T' through the passages U U',and U2, y the valves C, C', andfC2. ''he condensed steam inthe intermediate chambers Z" causes the oil to rise to the upper parts of the pipes T' beyond the 'valves C, C', and 02j The valves -B, ]3', and B2 'are then opened and mingled water and oil are forced into the chambers X' and through the passages V' into the conducting pipes G, G', and G2, and through them and the pipes H, H', and H2 to the part or parts to be lubricated. No oil can get intov the boiler through the pipe I, bccause the water in the chest L holds any oil which m'a'y escape backward through the yalves C, C', and C2 inthe upper part of the chest L. v v

For emergency purposes the pipes H-,H'g and H2 are extended directly into the lower chamber of the casing N and are there controlled by the valves E, E', and E2, whereby oill may be fed direct without the mixture of steam into an Y one of the pipes H H', or H2. Thus, i any one or more et the glasses D, D', or D2 are broken, there will be no interruption in the lubrication of any part. Cocks R and R' are provided for the pressure to the cylinder be- The piston Q is forced up-4 the cylinder M and the casing respectively for draining them out. The piston Q rests upon a support set. upright on the bottom of the cylinder M. Through this support a passage leads dow to the cock R. This ar.- rangement of the liiston, support, and draining passage, .prevents oil leaking from the f upper part of the cylinder into the drainage when the piston, Q rests upon the support so as to cover the draining passage.' Whenl it is desired to clean the oil out of the lubricator, the valve J is opened and steam blown through the upper part ofthe cylinder M,. the lower,` chamber of the casing N and out the cock R. In the sides of the cylinder :M

are provided the sight glasses K and K.

I do not-limit myselfto the exact form in which my invention is herein disclosed any further than is indicated in ythe following' f per portion of said chamber.

2. In a lubricator, 1n combination, an upright oil cylinder, a piston therein, 'a chamber connected withthe upper portion of said cylinder, a receptacle for water of condensaconnection w1th the chamber,

tion connected with the upper portion of said c'hamber and connected with the sourcev of steam supply at a point lower than said and means for directing iuid under pressure into the lower l j portion of said oil cylinder;

3. A lubrica-tor,- comprising a cylinder adapted to cont-aina lubricantvand a piston movabletherein, a chest on the top and side of said cylinder adapted to contain a fluid under pressure, upper and lower receptacles arranged adjacent said cylinder, a sight tube arranged between the receptacles and opening into the same, a lower receptacle having communicationwith the cylinder, said chest lhavlng commumcatlon lwith the lower part of the cylinder and the upper receptacle, means for controlling the flow of oil through the sight tube, and a pipe leading from the upper receptacle.

4. A lubricator, comprising an upright cylinder adapted to contain a lubricant, a piston therein, a support adapted to hold said piston -oil. the bottom of said cylinder, having a vertical passage closed when the piston rests thereon and valve-controlled means for allowing the bottom of said cylinder to be drained; upper and lower receptacles arranged adjacent said cylinder; a

chest on the top and vside of said cylinder adapted to contain iuid under pressure and having means for admitting sai fluid to the lower end of said cylinder and to said upper receptacle; Valve-controlled -means for recting the lubricant from said lower to said upper receptacle; and valv e-controlled means for directing fluid from said chest and the lubricant from said upper receptacle to the.

part to be lubricated.
