LUBRICATOR.

UNTTED STATES PATENT OFFICE IMPROVEMENT IN LUBRICATORS.
Specification forming partwof Letters Patent No. 185,516, dated December 19, 1876; application led November 11, 1876.
Similar letters of reference indicate corresponding parts.
Our invention relates to lubricators forautomatically lubricating the cylinders'of engines 5 and it consists of two valves oppositely arranged upon the ends of a common stem, and provided with seats upon opposite ends of a chambered tubular conductor that connects the oil-cup and steam-chest and is so arranged that steam-pressure from within the steam-chest closes the valve against the seat Aon the lower end of the tubular conductor,
and a removal of the pressure from the steamchest allows the valve to drop and permits the lubricant to enter the steamchest.
Referring to the drawing, A is the tubular conductor, having valve-seats a. formed on each end, and provided with a central chamber, b. One end of the conductor A is screwed into the steam-chest B, and the upper end receives the oil-cup O. D is a valve that lits the seat a on the lower end of the conductor A, and is provided with a stem or guide', c, that extends through the conductor A, and is threaded to receive the valve E, that ts the valve-seat a in the upper end of the conductor A. The distance between the valves D and E is greater than the length of the conductor A, so that when steam is admitted to the chest B the valve D is closed against its seat, and consequently the valveE is opened, admitting the lubricant to the chamber b. The
stem c is grooved throughout its length, to form passages for letting oil into and out of the chamber b. When the pressure is removed from the chest B the valves D and E drop, closing the upper end and opening the lower end ot' the tubular conductor A, permitting the oil contained by the chamber b to run into the chest B. The guide or stein c is bored from its lower end throughout the greater portion of its length, to lighten it, and also to admit steam for the purpose of keeping the upper end of the valve warm and by this means warming the lubricant contained byl the cup O.
We do not limit our improvement to the exact form shown and described, as it may be varied without departing from our inventionfor example, two valves having separate tubular stems or guides may be used, and the chamber b may be dispensed with.
With our improvement a valve and cylinder are regularly and eftectually lubricated, and a material saving in oil and labor is effected.
Having thus described our invention, we claim as new, and desire to secure by Letters Patent- Ihe combination with conductor A, having an inner oilreceptaele connected at one end with oil-cup, and at the other with steamchest, of the internal rod C, having reversed valves at its opposite ends, said valves being placed a little farther apart than their seats in the ends of the conductor, for the purpose specified.
