Y Application filed March 13, 1899. Serial No. 708.872. (No model.)

.To @ZZ whom 12m/ay concern:

Beitknown that I, LEOPOLD KAO'ZANDEE, a citizen of the United States, and a resident of the city of New York, in the county and State of New York, have invented certain new and useful Improvements in Lubricating Apparatus, of which the followingis a specification.

This invention has for its object to provide a. simple and efficient means for lubricating steam cylinders and valves, especially those which are subjected to variable steam-pressures, as is the case with the cylinders and valves of locomotive-engines. l

More particularly the invention is an improvement upon that class vof lubricators of which the lubricating apparatus set forth in Swifts patent, No. 272,793,0f February 20, 1883, is the type-i. e., a-lubricating apparatus in which a choke-plug-or a contracted or choked passage is employed at or near the steam-chest of the engine to intercept to a great extent the pressure from either the steam-chest or the lubricator and to equalize said pressure in the duct or pipe which conveys the lubricant from the lubricator to the steam-chest, with the consequent effect of equalizing also the flow of the lubricant. It has been found in connection with such lubricating apparatus that the choked passage at the steam-chest is liable to become clogged, thus rendering the lubricator inoperative, and different means havejbeen proposed for the purpose of cleaning and opening up the choke plug in case of clogging. means are either inconvenient or dangerous, as they require the stopping of the locomotive and consequent delay or mechanical manipulation on the part o f the enginemen while the engine is running. Toobviate these objectionable features of devices now known to me, I have perfected an improved steam-chest device in connection with the lubricator Whichniakes a clogging of the choke-plug during the run of the engine practically impossible.

I will first describe my improvements by reference to the accompanying drawings and will then point out more particularly in the claims those features which I believe to be new and of my o wn invention.

In the drawings, Figure 1 is a side eleva- All` such tion of so much of a locomotive boiler, cylinder, steam-chest, and lubricating apparatus as is needed to illustrate my improvements.

Fig. 2 is an'enlarged vertical central section 55 of the steam-chest attachment in which my improvements are embodied.

A represents the boiler of a locomotive, B

supply pipe of the lubricator; F, the sight- 7o feed glass; G, the steam-tube, which from thel top of condenser H conveys live steam through passages inside of the lubricator into oil-pipe I, the steam from the tube G and the oil from glass F passing together through pipe I into the steam-chest. The construction of such lubricators and the cooperation and function of the several parts composing the same are well known and need no detailed description.A To the top of the steam-chest I connect the casing K, which contains the several working parts of the attachment, by means of coupling-nut L, and at M connection is madewith the oil-pipe I.

N is a plug screwed into a bridge O, separating chambers P and P'. This plug is provided with a very small passage R and a larger passage R'. The small passage opens into the hollow chamber S of plug N, outlet from this chamber into chamber P being provided in the form of two or more rows of holes Si, drilled around the periphery of plug N. The large passageR opens directly into chamber P'.

, On a circular projection of bridge O is seated the disk valve T, provided with a central stem T', filling the passage R. When valve T is closed, as in the drawings, the stem T' closes the passage R. Into the periphery of disk T one or more rows of holes U are drilled. Valve loo vT is controlled by screw-threaded stem V and handle V.

It is evident from the drawings that when valve T is closed the lubricant and the steam coming down pipe I must pass from it into chamber P and thence to the steam-chest through holes U, small passage R, holes S, and chamber P. When valve T is opened, removing stem T from passage R', then direct communication is established between passages P and P by way of passage R'.

The operation of the attachment in connection with the lubricator and the steam-chest is as follows: The lubricator having been put into operation in the usual and well-known manner, oil and steam will pass from the lubricator, through oil-pipes N and passage R, into the steam-chest. The constant pressure of steam in pipe I toward the steam-chest enables the lubricant to force its way through the choked passage R, and in case a partial vacuum is formed in the cylinder by shutting off steam therefrom the small passage R arrests the downrush of steam through pipe I and maintains the steam at quite 01 nearlya uniform pressure, thus cqualizing the flow of thelubricant under all circumstances. If for any reason the enginemen desire to use handoilers, with which lubricators are usually provided, to feed intermittently a larger quantity of oil into the cylinder than would conveniently pass through passage R, or to oil the valves and cylinders in case the sightglasses of the lubricator should break, then valve T is opened, making the large passage R available for such purpose.

The holes U in valve T and the holes S in plug N form strainers at the inlet to and the outlet from passage R. The diameter of these holes is intended to be slightly less than that of passage R, so that any matter which will pass through holes U or S will readily pass through R without clogging the same. The number of holes U and S should provide an area twenty to thirty times that of passage R. At the same time each one of the holes U or S is preferably large enough to ad mit the passage through it alone of the normal volu me of the lubricant through pipe I. It is evident, therefore, that as long as one each of the holes U and S is open the lubricator cannot be rendered inoperative, and if the strainers are looked after and cleaned before the engine goes out on a run it is practically impossible that all the holes in the strainers should be clogged during the run of the engine, and the lubricator will therefore be eminently reliable and efficient.

The parts of the attachmentare so arranged that the straincrs can be got at readily whenever it is desired to clean them. It is also evident that delivery of lubricant from pipe I through passage R is independent of the strainer-holes U, so that even if all the holes U should clog up during the run of the engine by'opening valve Ta large and independent delivery-passage is provided for the lubricant from the hand oilers. In other words, the larger valve-controlled passage R is independent of and extends around not only the permanently open choked passage, but also the strainer at the inlet end of said passage,as well as,for that matter,the strainer at the outlet end of said passage.l

Having described my improvements and 'the best way now known to me of carrying the saine into effect, I state, in conclusion, that I do not restrict myself tothe structural details herein set forth in illustration of my said improvements, since manifestly thesame can be varied without departure from the spirit of my invention; but

Vhat I claim herein as new, and desire to secure by Letters Patent, is

l. A lubricator attachment comprising a casing adapted to be connected to the lubricator and steam-chest respectively and containing a permanently open choked passage, a strainer at one or both ends of the said passage, and a larger valve-controlled by-passage which is independent of and extends around both the choked passage and the strainer or strainers therefor, substantially as and for the purposes hereinbefore set forth.

2. A lubricator attachment comprising a easing adapted to be connect-ed to the lubricator and the steam-chest respectively, and containing a plug N which has a small permanently open choked passage,a strainer and a larger valve-controlled by-passagc which is independent of and extends around both the choked passage and the strainer therefor at the outlet end of the choked passage, substantially as and for the purposes hereinbefore set forth.

3. A lubricator attachment comprising a casing adapted to be connected to the lubricater and steam-chest respectively, and containing a small permanently open choked passage, a larger by-passage and a valve T which controls the by-passage, and is provided with a strainer for the inlet end of the choked passage, substantially as and for the purposes hereinbefore set forth.

4. A lubricator attachment comprising a casing adapted to be connected to the lubricator and steam-chest respectively and containing a largevalve-controlled by-passagc and a permanently open choked passage, protected at both its inlet and its outlet end by strainers, substantially as and for the purposes hereinbefore set forth.

In testimony whereof I have hereunto set my hand this 11th day of March, 1899.

LEOPOLD KACZANDER.
