To @ZZ whom it may concern: p

lBe it known that I, WILLIAM s. Pinson, a citizen of the United States,residin et Franklin, in the county ofv Venango andiState of Pennsylvania, have invented certain, new and useful Improvements in Lubricator Cups; and I do declare the following to ibo a full, clear, and exact description of the iriyention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the iigures of reference marked thereon, which form a part of this specification. 'y

This invention relates to certain (new and useful improvements in lubricatorsfV The invention has for its object the provision of a lubricator which is adapted for use in connection with steam chests, c'tylinders, and the like, where it is necessary to oil the moving parts of machinery while under steampressure. The device is also adaptged for use in connection with gas, air, and otl'ier forms of engines and is not only practicail in use, but is simple in construction and ,tomparatively inexpensive to manufacture, y With the above objects in View ttiie invenv tion finally consists in the novel construction, combination, and arrangements of ipart-s, as will be hereinafter more fully desgaribed in detail. l,

In describing the invention in dettail reference is had to' the accompanying lrawings, forming a part of this specication-, wherein like numerals of reference desig-nate like parts, in which- 2 Figure l is a top view of my iinpriroved lubricator. Fig. 2 is a side view of git-he same. Fig. 3 is a sectional side view of the same on the line A B of Fig. l. Fig. 4. is al. sectional side View of the same on the line @it D of Fig. l. Fig. 5 is a sectional plan viewl of a portion of the device on the line E F of Fig. 2. Fig. 6 is a sectional side view ot' the device on the line C D of Fig. l with the valve removed.

Referringv now to the drawings for a description of the device in detail, thfe numeral l designates the cup for confining the oil and has formed thereon and projecting,` at right angles therefrom the tubular stem It', which terminates in athreaded end l, by wl lich the same is attached in position for use. Across the base of the cup is formed a tapering opening orv seat 2, communicating with the interior of the cup and the hollow stein thereof. Fitted loosely into this seat or opening is the tapering plug-valve 3, which is held therein by means of the washer 4 and nut 5, arranged upon a threaded shoulder-at the small end of the valve. Formed within this plu g-valve are the chambers 6 and 6', both of which are similar in form and extend clear through the plug, but are formed at right angles with one another, so that when the hand-lever 7 of the valve is turned one-quarter revolution either one of the chambers is always in position to receive a limited supply of oil from the cup while the other one is discharging its supply into the tubular extension or stem to the point of lubrication.

rY/Vhen one chamber is discharging its contents against a steam-pressure, it is evident that the steam cannot enter the cup through either chamber or during rotation of the valve, as the valve will cut oft the entrance of the steam. oil, the steam which enters therein is able to exert an equal pressure upon both sides of the valve, especially with the addition ofthe y subchamber 8, which is formed in the wall of the seat and aids to balance the valve. order to exhaust the steam from the chambers during the rotation of the valve, I have' provided in the wall of the valve-seat a port 9, which extends from near the center of the seat to an outlet 9 beneath the washer 4. Vith this form of lubricator I am able to feed the lubricant into the side of the steam chest or cylinder.

I do not desire to confine myself to the eX- act construction of the detail parts, as such parts may be modified in form and the cup provided with a cap and one or more chambers than shown formed through the valve,

as well as other slight changes, without de-y When one chamber is discharging IOO :a g; ennuyer the oup to close the op nin 51g' in the base there of, independent nhainh [formed through the valve at right angles therewith which have different positioiiie along' its length, each of which is adapted to aueeeenivelycommunicate with and receive a quantity of oil direet from the Cup as the Valve is ronated and deliver the same into the tubular extension, an exhaust port or groove formed along the Valve-Seat to exhaust the steam from the ohambersas the Valve is rotated, and a chamber formed within the valve-seat opposite the tubular stein for the purpose of balancing the pressure upon the Valve.
