TIMOTHY HOLLAND, or TROY, NEW YORK.

LUBRICATOR.

srncmrca'rlolv forming part of Letters Patent No. 262,774, dated August 15, 1882.

' Application filed June 26,1882. (No model.)

To all whom it may concern:

Be it known that I, TIMOTHY HOLLAND, of the city of Troy, county of Rensselaer, and State of New York, have invented a new and useful Improvement in Lubricating Devices, of which the followingis a specification.

' My invention relates to that class of devices termed lubricators, which are used to contalc and supply material for lubricating, the

working parts of machinery, and the object of my improvements being to better adapt such devices for use upon locomotives.

The invention consists of certain improvements upon the method of constructing lubricators patented by John Absterdam, November 21, 1854, and in which the pressure of water beneath the oil in a closed vessel caused the oil to rise and flowtherefrom, so as to descend ina visible form to the point of application. I

My invention consists, also, as will hereinafter be more fully described, in the combinathe lubricators when the steam has been shut off from the steam-cylinders and the locomotive is running on a downgrade.

My invention also consists, as will hereinafter he more fully described, in the combina-' tion of two lubricating-vessels of the same e constrnction, having a united steam-pipe connectionwith the boiler, and each of the two lubricators constructed with a branch steampipe connection, one of which is made with the interior of the lubricators and the other connected with the conduit-pipe, which con-- veys a current of mingled oil and steam from .the lubricators to the steam-cylinders, the object being to relieve the vacuum tendency produced in the steam-cylinders when the steam is shut 05 from them while the locomotive is running on a downgrade, and to prevent this vacuum tendency from drawing the oil from the lubricators'. I

My invention further consists, as will herethe oil descends in drops.

inafter be more fully described, in the combination, with he pipe containing the glass tube through which the oil passes in visible drops to the point of application, of an attachable and detachable clamp and hand-screw constructed to close up the sight-openings'in the pipe surrounding the glass tube temporarilyin case the tube should be broken, so that the action of the lubricator can continue until an opportunity occurs to replace the tube.

My invention embraces other features, which will-be fully hereinafter described, and pointed out in the claims. I In the accompanying drawings, forming a part of this specification,there are three figures illustrating my invention, and. in all of them the same designation of parts by letter-refer- .ence is used.

Figure 1 shows in vertical section two lu bricators constructed alike, each of which, and both as connected, contains my invention. Fig. 2 is-a horizontal sectiontaken transversely on the line .70 of Fig. 1. This illustration also shows the clamping device constructed to close up the sight-openings in the pipe containing the glass tube through which Fig. 3, illustrates a vertical section taken on the line w w. of Fig. l, and at right angles to the latter, the transversely-central parts between the ends being omitted.

The two lubricating devices'are constructed alike. They are designated at X and X X,

and their duplicated partsin each are indicated by the same reference-letters, and as follows:

The letter A designates a condensing-chamher connected with thesteam-pipe S which X .at the branch S connects with the steam-boiler.

Theletter A indicates an oil and'water chamber, which connects with the upper condensing-chamber, A, by means of the con-- nccting-pipes d and a there being arranged between these pipes the valve V The letter 13 indicates an opening and plug in the chamber A for supplying oil to the same, and I? designates a small cock for drawing off the water from this chamber A From this latter chamber, at its top, is connected the oil-pipe 0 on which isplaced the valve V and at 0 this pipe leads downwardly into a glass tube, G, the latter being placed within the pipe I, which has constructedon opposite sides, at h sight-openings, through which the descending oil may be seen. The oil-pipe 0 terminates in a pendent nozzle having a button upon the pipe above the pendent discharge end.

Within the chamber A. there is shown the steam-pipe 3", opening into this chamber, so as to receive steam under pressure therefrom. This steam-pipe S passcs downwardly through the condensing-ch21 mber A into the cored armpipc P at S", where it connects with the annular chamber a, formed in said pipe, and trout which the steam under pressure is forced through the glass tube G, being deflected to the sides of the latter by the flat deflectingring on the oil-pipe above the discharge pendent nozzle end of the latter. From this pointthe dropping oil and the steam pass downwardly and around the threc-sided' stem of the puppet-valve it within the oil-conduit pipe Ufland from thence into the annular space S in the horizontal pipe I, from which they pass into and through the conduit-pipe O, which connects with the steam-cylinder. This manner of constructing an oil-delivery pipe, a con necting glass tube, and an impelling steampressure is substantially the same as that shown in Patent No. 243,900, which was granted to me July 5, 1881, with the exception that in the patent named the steam-current used to impel on the dropping oil to the point of its application was taken directly from the boiler, while in the application herein shown the steam is taken from the interior of the. condensing-chamber. v

To protect the glasstubes of lubricators, through which the oil and steam move, I surround them with the protecting-pipe P which has oppositelyarranged sight-openings a a, Fig. 2, and combine with the latter a clamp constructed with the stopper-plugs a n and the screw and thumb piece W, so that in case the glass tube becomes broken thelubricator may be temporarily used without the tube, and until the latter is replaced.

To prevent any unusual back-pressure from the steam-cylinder, and the consequent churning up of the oil and water, so as to interfere with the uniform flow and delivery of the oil from the lubricator-vcssel, I construct within the oil-delivery pipe 0 the puppetyalve n, the stem of which is threesided, so as to al low a passage along the stem and between it and the sides of the pipe of the oil being supplied to the conduit-pipe leading to the steamcyliuders L, the button of this valve n seating to close the pipe 0 in the rounded top a of the annular chamber S, which forms the out lot of the latter pipe, when any unusual pressure from the cylinder causes the valve to rise and thus close.

When steam is shut off from the steam'cylinders of a locomotive, as is the case when the latter is runningon a downgrade, the vacuum tendency produced in the steam cylinders seawadraws the oil outfrom thelubricatingvessels, so as to sometimes empty them. To avoid this ditliculty I connect the oil-conduit pipe leading to the steamcylinders directly with the boiler, and by which this tendency is relieved. This auxiliary pipe is designated at e, which at its upper end connects with the steam-pipe S, and its lower end, 0', opens into theoil-conduit pipe 0 part of the arm P being cored out to form a continuation of the pipe 6 have shown this improved feature of an auxiliary steam-pipe connecting the oil-conduit pipe that leads to the cylinder as applied to a duplicated lubricator, each of which two connects separately with-one of the steam-cylinders, it may be applied in the same manner each of the branch cylinder connections made with a single lubricator. 1

The condensing-chamber A serves to collect water and receive pressure from the steamboiler by means of the pipe S and this received pressure and accumulated condensation it transmits to the cylinder A through the pipes d and d the amount of water delivered and steampressure transmitted to the lower chamber, A being regulated by the interme diately-placed valve ,V, l

By thus constructing the lubricating device, so as to take steam from the interior of the steam-supplied chamber A through the pipe S with which to force the delivery of the oil toward the point of its use, and thus connecting this chamber A with the chamber A to utilize thissame steam-pressure to supply water to and to force the overflow of oil from the chamber A, a single steam-connection with the lubricator is made to perform several important uses within the lubricator in a manner and by a means of construction that insures uniformity of pressure within the lubricator and a regular delivery of the oil from it.

The two lubricating-vessels X and X X have a branch connection at 8*, which at S connects them with the boiler, and each of them is a duplicate of the other, and has a conduit-pipe to connect it separately with one of the steamcylinders. This branch connection to supply the interior of each lubricator with steam, for

scribed, is also branched to supply an auxiliary steam-pipe connection with the conduit-pipes of each lubricator, so that a single boiler-contion made at S operates both of them.

I am well aware that water and pressure from the steam-boiler have been used to float its point ofapplication, as shown and described in the patent of Abstcrdam, before alluded to. I am also aware that all the features of my improvement and invention herein specifically relating tothis older method are limited to my improved construction and the means which I employ to make this older method better adapted to specific uses.

- Having thus described my invention, what and so as to perform the same useful office to the purposes hereinbefore named and de-v the oil within and to accelerate its delivery. from .an inclosed vessel in a direction toward While I 262,774 v Q l 3 I claim, and desire to secure by Letters Patent,
