LUBRlCATOR FOR FLAKED GRAPHITE.
SPECIFIGATION forming part of Letters Patent No. 746,837, dated December 15, 1903.
Application filed April 28, 1902'. derial No. l04,975. (No model.)
To all whom, it may concern:
Be it known that I, ALBERT D. HOMARD, a citizen of the United States, residing at Massillon, county of Stark, State of Ohio, have invented a certain new and useful Improvement in Lubricators for Flaked Graphite; and I declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to'which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
This invention relates to lubricators, and has for its object an improved lubricator adapted to employ flaked graphite or finely ground graphite for lubricating purposes.
In a patentgranted to me Septem ber 29, 1896, No. 568,616, is described a lubricatorintended to be employed for the purpose of dispensing flaked graphite. I have found in using the lubricator therein described that a difticulty occurred because of the liability of the steam that passes into the lubricator to exert pressure on the piston-valve to become loaded with powder of the graphite that passes down in proximity to and at times through the steam and to deposit the graphite in the passages to the lubricator, thereby clogging the valves and the passages. By the improvemeut hereinafter described this difficulty is overcome.
In the drawings, Figure 1 is a vertical crosssection of the lubricator. Fig. 2 is an enlarged detail of the check-valvein the steam-' passage.
In the present case the lubricator is shown connected to a chest-plug of a locomotive-cylinder.
A indicates the reservoir in which the pewdered graphite is contained. The powdered graphite is fed from this reservoir by a stationary feed-tube B, that is secured to the bottom of the reservoir and leads upward to near the top thereof. Preferably, but not necessarily, the tube leads through a piston D, which presses upward against the powdered graphite supported above it. The powdered graphite feeds'outward through a passage 2 in the coupling 3, past a hand-actuated valve l, and past a check-valve 5, which seats upward and is near the mouth of the tube 2, where it leads into the chest-coupling 6, by which the device is coupled to the engine or to the steam-chest. The check-valve 5 is pressed upward against its seat by a coil- .spring 7, held in place by a perforated nut 8.
The piston D is driven upward by steam that enters the chamber a through steam'passage 9, into which the steam enters by a passage through pointed nozzle 10, that projects into the chamber within the coupling 6. The nozzle 10 is provided with a check-valve 11, which is opened upwardly by the force of the steam. A hand-valvelZ is arranged to regulate the admission of steam through the passage 9 into the chamber a.
The ordinary coupling for the oil-lubricator which employs the tallow-pipe 13 and admits oil into the engine by the perforated check-valve 14 leads into the coupling 6, which is utilized for both the dry lubricant and the oil lubricant.
What I claim is .1. In an automatic feeder for powdered graphite, a cylinder, a piston therein, said cylinder being provided with a chamber on one side of said piston adapted-t0 contain powdered graphite, a feed-passage for said graphite leading from said chamber into a chamber containing a variable steam-pressure, an induction-passage for steam opening into said cylinder upon the opposite side of the piston to the graphite-chamber and a nozzle surrounding the end of the steam-passage projecting into the variable steam-pressure chamber from an upper Wall of said chamber.
2. In an automatic feeder for powdered graphite, a cylinder, a piston therein, said cylinder being provided with a chamber on one side of said piston adapted to contain powdered graphite, a feed-passage for said graphite leading from said chamber into a chamber containing a variable steam-pressure, an induction-passage for steam opening into said cylinder upon the opposite side of the piston to the graphite-charnber and a nozzle surrounding the end of the steam-passage projecting into the variable steam-pressure chamber from an upper wall of said chamber, a check-valve in the steam-passage opening toward the cylinder, and a check-valve in the graphite-passage opening toward the variable steam-pressure chamber.
In testimony whereof I sign this specification in the presence of two witnesses.
ALBERT D. HOMARD.
I Witnesses: CHARLES F. BURTON, MAY E. KOTT.
