LUBRICATO R.

SPECIFICATION forming part of Letters Patent No. 298,011l dated May 6, 1884.

Application filed October 23, 1883. (No model.)

To all whom, it may concern Be it known that I, GEORGE MGNEIL, residing at Chicago,l in the county of Cook and State of Illinois, and a citizenv of the United States, have invented new and useful Improvements in Lubricators, of whichl the following is a full description, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation; Fig. 2, a section on line :r of Fig. 1, showing the feed-valve for the oil or lubricant; Fig. 3, a section on line y of Fig. 2; Fig. 4, a transverse longitudinal section through the chamber for the passage of the steam and oil; Fig. 5, a vertical longitudinal section; Fig. 6, a'detail showing the pressure-pipe applied to the end of the a modiiication of the filling-plug. p

This invention relates to that class of lubricators in which the oil is forced and fed from the reservoir by the pressure of a column of water, and has for its objects to simplify the construction and improve the operation of this class of lubricators, as hereinafter more fully described; and its nature consists in the several parts and combinations of parts hereinafter described, and pointed out-in the claims as new. Y

In the drawings, A represents the reservoir for the oil or other lubricant, which may be made in a cylindrical form, of brass or other suitable material, or may have a body of glassV and ends of any suitable metal, as may be dc- Sired.

B is the pipe for the water of condensation, which furnishes the pressure required for feeding the oil or other lubricant. The discharge end of this pipe, as shown, is contracted at B', to increase the amount of pressure from the Water in the pipe; but, if desired, this pipe B may be of the same diameter its entire length.

C is a connecting-pipe, of smaller diameter than the pipe B, to the discharge end B of which pipe it is connected by an elbow, a, anda vpipesection, a', in the formof construction shown; but the connection may be made in some other suitable manner. This pipe O is provided with a valve-chamber, C', for the rcception of a suitable valveto control the feed through the pipe C, which valve is operated by a hand-whee1,C,.or in some other suitable .tral opening, c, from which a passage, c', leads in a diagonal direction, as shown, and com municates with a transverse passage, c, in which is arranged a valve, d, the stem d of which is screw-threaded, and passes through a stuffing-box on'the side of the plug in the usual manner, and `is operated by a' hand- Wheel, d. This valve d controls the opening into a discharge-nozzle, e, which nozzle communicates at its lower end with the transverse passage c, so that the oil or other lubricant will pass into vthe opening c, thence into the passage c to the passage c, and into the discharge-nozzle'e.

F is a tube of glass, through which the oil passes to the point of discharge, the tube being made of glass in order to observe whether the feed is working in a correct manner. This tube at its lower end' is located around the feed-nozzle e, as shown in Fig. 3, and is held in place and connected with the plug E by entering an opening in a nipple of the plug,

which'nipple receives a suitable stuffing-box.

G is a chamber, made of brass or other suit,- able material, and having a transverse opening, f, which, when the parts are together, comes in linewith the opening in the plug E, for the reception of the glass feed-tube F, so

that such feed-tube can be inserted in position.

and on the side of the chamber G, around the The opening f is closedby a suitable plug, f', j

openingf, is a screw-threaded nipple, f, to 'l receive a stuffing-box and make a tight joint around the feed-tube F. The chamber G is j provided with two longitudinalY openings, g

and g', one of which, g, extends from one endl of the chamber nearlyV to the opposite end in 1 one form of construction, and `the other, g',

extends from the end ofthe chamber to the"y opening f. The opening g passes around the TOO opening f, as shown in Fig. 4, and communicates with a pipe, l1', which pipe extends into the pipe B, and is bent around so as to form a U-trap, and this opening or passage g is for the passage of the steam from the steam-pipe to enter the pipe h, and pass therefrom in the form of spray and be condensed and iill the pipe B with this water of condensation. The other opening, g, is provided with a pipe, h', which, as shown, is curved downward, which pipe,when the parts are together, comes inside of the steam-pipe, to which the chamber is connected, the chamber at the supply end, as shown, having a screw-threaded nipple for the purpose of making the connection with the steam-pipe.

H is a standard, one end of which rests on the Atop of the reservoir A, and is connected therewith by screws or in any other suitable manner, and the other end of which enters a boss formed on the under side of the chamber G. This standard H furnishes a support between the chamber G and reservoir A, and is for the purpose of giving greater rigidity to the parts when connected together.

I is a plug or stopper which enters an opening in the top of the reservoir A, through which opening the reservoir can be filled with oil or other lubricant.

J is a draw-off cock attached to the bottom of the reservoir A, through which the sediment can be drawn oli' and the reservoir emptied, if desired.

The operation is as follows: The device is attached to the steam-pipe by connecting the supply end of the chamber, G with the steampipe through the screw-threaded nipple on the end of the chamber, or in any other suitable manner, the pipe h being in the opening g' and passing into the steam-pipe. The steam passes into the opening g, thence into the pipe h, where it is condensed, and passes in the form of spray into the pipe B, passing out at the discharge end B ot' such-pipe into the pipe C, and from this into the pipe D and into the chamber A; and the amount of water which passes through the pipe C and enters the reservoir A is regulated by the valve in the chamber C. The water as it enters the chamber A displaces the oil or other lubricant in such chamber, which passes into the opening c, thence through the openings c c into the nozzle e, from which it passes into the feed-tube F to the opening g', and through the pipe h into the steam-pipe, for lubricating purposes, and the amount of the feed for the oil or other lubricant is controlled and regulated by the valve d.

The device is very simple in construction,

as it consists, essentially, of a reservoir or rechamber for the passage of the steam from the steam-pipe to the feed-pipe, and for the passage of the oil from the oil-feed tube to the steam-pipe, and by this construction it will be seen that only two valves are necessaryone for controlling the passage of the water of condensation to the reservoir or receptacle, and the other for controlling the feed of the oil or other lubricant.

It will be further noticed that by the construction shown and described the passage for the steam and the passage for the oil to the steam-pipe are wholly disconnected and have no communication with each other, the result being that neither passage is in any manner affected by the other, leaving both passages free to do their required work without interfering with each other. The construction also enables a ready removal of the feed-tube for the oil to be had, for the purpose of cleaning or otherwise, to do which all that is required is to loosen the stufling-boxes on the chamber G and plug E, which surround the oilfeed tube, and remove the plug f', when the feedtube can be pushed through the opening f and be removed, and when cleaned the tube can be inserted through the opening f, and the stuffing-boxes tightened and the plug f inserted, when the device is again ready for use.

As shown, the reservoir, when the device is in position for use, is adjacent to the steampipe, and by this arrangement suticient heat is generated to keep the oil or other lubricant in the reservoir in proper condition to be fed through the pipe F, and it will be further seen that the oil or other lubricant must pass from the tube F through the passage g in the chamber G, and the steam for supplying the water of condensation also passes through this same chamber, the result being that the passage for the oil is kept sufficiently heated to prevent any sticking or adhesion of the oil or lubricant in its passage to the steam-pipe.

If desired, a check-valve could be provided, as shown in Fig. 4, by means of which the flow of the oil or lubricant to the passage g could be shut oif, and a similar valve could also be provided for the passage g, by means of which the steam could be shut off from the pipe B.

Instead of having the filling-plug I located on top of the reservoir A, such plug might be located ou the side of the plug E, as shown in Fig. 7, communication being had with the interior of the reservoir through the openings c c.

As shown, the pressure-pipe B is attached to the side of the chamber G 5 but such pipe could be attached to the end of the chamber, as shown in Fig. 6, a suitable stuffing-box or coupling being used, and when so attached the passage g should extend entirely through the chamber G, so as to have communication with the pipe B, and the trap h can be dispensed with. This trap h can also be dispensed with, if so desired, when the connection of the pipe B is made as shown in Fig. 5.

If it is desired to blowout the oil-receptacle and oil-feed pipe, it can be readily done by IOO IIO

opening the ,discharge-valve of the receptacle and shutting off the steam from the passage g, causing it to pass into the passage g, and thence into the oil-feed pipe F and reservoir, and when the reservoir is cleaned or blown oft' it can be refilled and made to operate, as Y before described, by closing the dischargeval've of the reservoir and allowing the steam to pass to the pipe D.

`What I claim as new, and desireto secure by Letters Patent, is as follows:

1. The chamber G, having a passage, g, for steam and a passage, g', for lubricant, in combination with a pipe, B, for the water of condensation, reservoir A, having communication with the pipe B, and oil-feed tube F, substantially as and for the purposes specified.

2. The chamber G, having a passage, g, for

steam and a passage, g', for oil, in combination with the pipe B, trapipipe h, reservoir A, communicating with the pipe B, and feed-pipev F, substantially as and for the purposes specified. Y

3. The reservoir A and' plug E, having an opening, c, andpassages c c, in combination with the feed-tube F and feed-nozz1e e, substantially as and for the purpose specied.

4. The reservoir A, pipe B, having thetrappipe h located therein, and feed-pipes C D, in combination with the plug E, feed-piped?, and chamber G, having the passages g n', substa'- tially as and for the purposes specified.
