IMPROVEMENT IN STEAM-CYLINDER LUBRICA TORS.

Specification forming part of Letters Patent No. 155,?67, dated October 6, 1874 application filed September 12, 1874.

To all whom it may concern:

Be it known that I, LEVI F.'SMITH, of Philadelphia, in the county of Philadelphia and in the State of Pennsylvania, have invented certain new and useful Improvements in Steam- Oylinde'r Lubricators; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

The nature of my invention consists in certain improvements upon the steam cylinder lubricators for which Letters Patent Nos. 107,826 and 140,958 were granted to me September 27, 1870, and July 15, 1873, respectively, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which- Figure 1 is a side elevation, partially in section, of a steam-cylinder lubricator embodying my invention. Fig. 2 is an enlarged section of the globe at the bottom of the oil-reservoir, with its valves. Figs. 3 and 4 show the mode of fastening the cap at the top of the oil-reservoir. Figs. 5, 6, and 7 show the construction of the valve-chambers and valves for the gagetube outside of the oil-reservoir.

A represents the oil-reservoir, with the globe B screwed into its bottom. This globe is prcF vided with two valves, 0 and G, and constructed in the same manner as described in the Patent No. 140,958, above referred to, so as to admit of feeding the oil either by a condensing feed; or positive feed, as desired. The valve 0, which is used for the positive feed, is provided with a short stem or teat, a, which passes into and through the valve-opening,

and is beveled on one side, as shown at m, Fig. 2. The hand-wheel of this valve is graduated on its periphery, so as to set the valve to feed as manydropsperminute as may be desired.

It will readily be seen that if this valve were not provided with the teat a, the slightest movement of the valve would remove it from its seat and admit oil all around it through the valve-opening, and hence the graduations on the valve-wheel would have to.

' be so very small and close together that it would be almost impossible to set the valve to feed the amount desired. By the addition, however, of the teat a, beveled on one side, the valve-opening is so slowly enlarged that the graduations may be made at a comparatively great distance apart, and the valve can easily be set to feed any number of drops desired. In the top of the reservoirAis the aperture b, through which the oil is admitted, and

around said aperture is formed a chamber, l), which acts as a funnel in filling the reservoir.

On the rim of this chamber are lugs cl cl, to

engage with corresponding lugs e e on theinside, at the bottom of the cap D, for hold ng the cap on the reservoir. In the cap D is a horizontal plate or partition, f, in the center of which is an aperture for the insertion of the lower end of the sleeve h, which screws through the top of the cap D, and is, at its upper end, provided with a hand wheel, E. Through this sleeve it passes the valve-stem h, having a disk, 70, and valve 2' at its lower end, between which is a circumferential groove, 2.

When the cap is put on, the sleeve h is screwed down, forcing the valve z'flrmly to its seat, and at the same time fastening the cap firmly. In case of leakage by the wearing of the valve i or its seat, when there is no time to grind the valve down, a washer, an, of rubber,leather, soft metal, or other su table material, is placed in the circum ferential groove 2, between the valve t and disk 70, which will make the joint between said disk and top of reservoir perfectly steam-tight. On the sleeve h, below the wheel E, is placed a lever-nut, G, to lock the cap. This is, however, not necessary on stationary engines, only on locomotives, where the jarring might otherwlse loosen the cap.

From the top of the oil-reservoir A a pipe, H, leads horizontally outward into a valve-v box, I, which is by a partition, a, divided into two chambers, n and M. The pipe leads into the chamber n and directly oppositesaid pipe, on a line therewith, is a tube, 8, with a pet-cock, J, as shown in Fig. 1. In the partr tion nis a suitable opening,forming a communication between the chambers a a and said opening is closed by an ordinary globe-valve, 1 entering from the side of the valve-box I. From the bottom of the reservoir extends a pipe, H, leading horizontally outward into a valve-box, I, having an outlet, 8, and with or without a pet-cock, J. Between the two valveboxes is inserted a glass tube, L, into which oil flows through the tubes and chambers from the reservoir, for the purpose of indicating the quantity of oil in the reservoir.

The object of thus arranging the valve 11, and of the addition of the pet-cock J, is, that in case the pipe Hshould become clogged up, it can be cleaned out without removing the glass tube L, by simply opening the pet-cock J and inserting a wire, which will pass straight into the pipe H and clean the same. The valveboX may be provided with a simple three-way cock, I, as shown in Figs. 6 and 7, the box having an outlet or pet-cock, s, on a line with the pipe, and a passage, t, to communicate with the glass tube. This will answer the same purpose as the tWochambered valve-box, with pet-cock and globe-valve, above described.

In Fig. 1 of the drawing I have shown, at the upper part of the reservoir, the two-chambered valve-box, pet-cock, and globe-valve connected to the pipe H. When these devices are employed, they are to be used upon the pipe H at the bottom of the reservoir, also.

In Fig. l, at the lower part of the reservoir, I have shown a three-way cock in the valvechamber 1, with an outlet, 8', and pet-cock J. When this liquid'controllin g device is employed, it is used upon the pipe 1:1 at the top of the reservoir, also. The pet-cock J is not really necessary when the three-way cock is used. The two forms are shown in one figure for convenience in illustrating.

The employment of either the two-chambered box and globe valve or the three-way cock will answer equally well to accomplish what I desire in connection with the parts specified.

I do not wish to be understood as herein specifically claiming either of said devices, nor

is closed and the valve 0 is opened, when the oil will pass directly from the bottom of the oil-reservoir, and, by setting said valve 0 ac-' cording to the graduations on its hand-wheel; the number of drops to be fed per minute is easily regulated.

On the rim of the graduating-wheel of the valve 0 is a stud, w, to connect with a rod leading to the cab of the locomotive, so as to open the valve when running down grade, as then the steam-is shut off.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of the globe B, the graduated hand-wheel, the valve-stem, and the globe-valve O, with teat a, having bevel at, all

substantially as and for the purposes herein set forth.

2. The combination, with the chamber I), having valve-seat I), of the valve-stem h, disk 7c, circumferential groove 2, valve 2', and packing m, as and for the purposes set forth.

3. In combination with the screw-sleeve h, "alve-stem h, disk 70, and valve 1', the lockin g hand-lever G, with nut, all substantially as and for the purposes hereinv set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 8th day of September, 1874.
