CHARLES M. BYRD AND GEORGE H. TRAVIS, OF BATTLECREEK, MICHIGAN.

LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 779,026, dated January 3, 1905.

Application filed April Z3, 1904. Serial No. 204,657.

To all whom t Netty concern:

Be it lr'nown that we, CHARLES M. BYRD and GEORGE H. TRAVIS, citizens of the United States, residing at Battlecreek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Lubricators, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates more especially to that class of lubricators designed for use upon locomotives and for this purpose is arranged to feed both sides of the engine and the air-pump separately and independently.

The object of this invention is to provide means for positively delivering the required amount of oil to each of the several steamchests without danger of cross feeding or burning the lubricating elements, as Will hereinafter appear.

In the arrangement of parts our lubricator consists of a cylindrical oil-reservoir upon which is mounted the condensing-chamber, which is divided into several compartments by vertical walls reaching nearly to the bottom of the chamber, where they are united by a common passage underneath the walls. Displacement-water from the condensing-chamber is conducted to the bottom of the oil-reservoir by means of a pendent tube and connecting valved passages. The steam connection to the condensing-chamber is below the oil-outlet lines, thereby promoting condensation and preventing the oil from being exposed to the direct iniiuence of live dry steam, which would damage or destroy the lubricating elements in the oil, especially if used on very high pressure, as is now common. As the compartments in the condensing-chamber are absolutely without intercommunication in the line of oil-passages, it is obvious that crossfeeding is impossible. The peculiar manner of making the steam connection not only prevents undue and dangerous heating of the oil, but forms a Water-trap which eiiectually prevents oil entering the boiler from the lubricator under any circumstances. The condenser and oil-reservoir being an integral casting, all unnecessary joints are avoided. The close proximity of these chambers also insures the oil in the reserv'oiralways being warm enough to flow readily regardless of the temperature of the air surrounding the cup.

In the accompanying drawings, Figure l is a front central vertical section. Fig. 2 is a vertical cross-section, and Fig. 3 is a horizontal section through dotted lines in Figs. l and 2.

Similar parts are indicated by like letters in each of the views.

A is the oil-reservoir.

a is the condensation lead-pipe.

Bis the condensing-chamber,with compartments b S is the steam-pipe connection to boiler.

e e e are the openings from steam-line into condensing-chamber compartments.

g g g are the sight-glasses.

G G are the glass caps.

V V V are the feed-regulating valves.

W is the regulating-valve for displacement- 'water.

K K K are the inlets to regulating-valves.

t 7," t are the oil-drop nipples.

/t la la /L are the valve-stem boxes.

71 7l z' r1 are the box-gland nuts.

s s s are cap-plugs.

p is a pipe-plug for one end of steam-inlet passage.'

D is a bracket-stud to support the lubricator in position.

F is the filling-plug.

f is the filling-opening.

C C C are the choke-tubes.

E E E are the delivery-nipples.

U U U" are the pipe-unions.

T T T are the tallow-pipes.

m a are holes connecting displacement valve and tube with condenser and the oil-chamber.

The operation is as follows: Steam from the boiler having been admitted to pipe S and the condensing-chamber filled with -water up to line of oil-outlets, the regulating-valve to( displacement-water is opened and the feedvalves V V V adjusted to meet expected requirements, water will pass down tube c as fast as room is made for it by escape of oil upward through nipples t t/ t to the several compartments and tallow-pipes leading therei from'. As the steam-inlet to the condensingchamber from boiler is submerged, it is obvious that the oil and steam cannot come into a direct contact and only oil and water can pass from the chamber to the tallow-pipes, thereby not only preventing the burning of the oil and consequent damage to same, but leaving no burned residue to clog and obstruct the talloW-pipes. Y

Having thus fully illustrated and described our invention, what we claim as new, and desire to secure by Letters Patent of the United States, is-

l. A lubricator consisting of a casting having an oil-reservoir and a condensing-chamber therein, said condensing-chamber having partitions forming compartments each closed at the top to prevent cross-feeding of oil therein, communication being established between each of said compartments and the oil-reservoir and means for regulating said communications, and the wall of each of said compartments having an oil-outlet and a steam-inlet.

2. The combination in a lubricator of an oil-reservoir and a condensing-chamber separated by a partition, said condensing-chamber having iianges depending from the top thereof forming compartments therein, nipples in the condensing chamber providing communication With the oil-reservoir and a valve for regulating each of such communications, there being an oil-outlet and steam-inlet in the wall of each of said compartments, and a condensation-pipe leading from the condensing-chamber to the oil-reservoir.

3. In a lubricator, a casing having a partition therein forming an oil-reservoir and a condensing-chamber, said condensing-chamber having iianges depending from the top thereof forming compartments therein, an oilnipple and regulating-valve located between each of said compartments and the oil-reservoir, and said casing having the steam-inlet located below the oil-outlet therein to each of said compartments.

4. The combination in a lubricator, of a casing having an oil-chamber and a condensingchamber, nipples and valves for regulating communication between said chambers, observation-glasses in said condensing-chamber opposite said nipples, said casing having an oil -outlet near the top of -the condensingchamber and there being a steam-inlet in the casing connected to saidcondensing-chamber below the water-line therein.

In testimony whereof1 We affix our signatures in presence of two witnesses.
