SPECIFICATION forming part of Letters Patent No. 741,809, dated October 13, 1903.
Application filed July 30,1902.
To all whom it may concern-.-
Be it known that I, GEORGE EULARKn, a citizen of the United States, residing at Fenton, in the county of Genesee, State of Michigan, have invented certain new and useful Improvements in Oil-Cups for Engines; and I do declare the following to be a full, clear, and exact description of theinvention, such, as will enable others skilled in the art towhich it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.
This invention relates to an oil-cup for .explosive-engines; and it consists in the construction and arrangement of parts hereinafter fully set forth.
The object of the invention is to provide simple and efficient means for heating theoil in the oil-cup, so as to render it sufficiently fluid to readily feed into the cylinder even in extremely cold weather, th'erebyinsuringper- .fect lubrication of the piston under all conditions'.
The above object is attained by the association and arrangement of parts illustrated in the accompanying drawings, in which- Figure 1 is an elevation of my improved oil-cup, showing its connection with the water-pipe leading'from the jacket of the cylinder audits means for. connection with the cylinder. Fig. 2 is a vertical section therethrough. Fig. 3 is a horizontal section as on line 3 3 of Fig. 2. Fig. 4 is a view, partly in section, showingthe oil-cu p connected with the cylinder and with the water-pipe which water-space around the cyl-.
leads from the inder. A
In many instances where explosive-engines are used for stationary work they are located in an exposed position, so that in cold weather it is difficult to keep the oil sufficiently fluid to cause it to flow readily into the cylindera condition which sometimes results in the engine runningdry.
By means of my improved oil-cup I am enabled at all times tomaintain the oil at such a temperatureas to insure a perfect feeding thereof into the cylinder under all conditions of temperature.
Referring to the characters-of reference, 1
Serial No. 117,645. (No model.)
designates an oblong coupling having ihreaded apertures at its ends in which may be screwed the water-pipe 2, leading from the water-space 3, which surrounds the cylinder e, the water being kept in constant motion through said space and the pipe 2 by a pump or other suitable meansinot shown) for the purpose of keeping down the temperature of the cylinder, as is well understood in the art. Within the coupling 1 is a central core 5, having an oil-chamber 6 therein. Passing on either side ofisaid core is a channel 7, which communicates with the pipe 2 at opposite ends of the coupling andestablishes a passage-way for the flow of water through said coupling around said core. lilounted upon the upper face of the coupling 1 is a glass oil-cup 8, which is preferably cylindrical in form and which is closed by a cap 9, having interposed between it and the upper edge of the cup a gasket 10; The lower end of the cup is seated in an annular recess and rests upon the asher or gasket 11.
Depending f-w'in the cap 9 is a central tube 12, which extends downwardly through the cup and oil--chamber and is screwed at its lower end into'a threaded opening at the hot-.
tom of said chamber. Formed in the wall of the tube 12 near its lower end is an oil-port 13, through which the oil passes from the chamber 6 into said tube. Screwed into" a tapped-opening in the under side of the coupling 1 and in vertical alinement with the tube 12 is a hollow nipple 14; through which the oil is adapted to flew; Passing downwardly through the tube 12 and into the nip ple lat is a needle-point valve 15, the stem 16 of which is threaded in the cap 9,,so as to enable said valve to be adjusted to regulate the flow of oil through the nipple 1% by increasing or decreasing the distance between the point'of said valve and its seat 17 within said nipple. After adjustment the valve may be secured by the" lock-nut 18.
Below the nipple 14 is a sight-feed glass 19,
' through which the oil is adapted to pass and.
which is held in place by asurroundi'ug an,- nular casing 20, whose upper end is threaded to screw onto the threaded flange 21 of'the nipple, the upper end of said glass bearing against the washer 22 and the lower end resting upon the Washer'23, whereby theglass is securely held in place and a' tight joint is made between its ends and the connected parts. The lower end of the casing is provided with a threaded stem 24:, adapted to screw into the c linder, as'shown in' Fig, 3,
' and through sai stemis an oil-discharge passage-way 2a, which communicates with-the port 26, leading into the cylinder. Formed in the casing 21 is a side opening27, through i which the; glass 19 may be -seen, enabling the engineer to note the feed of the oil as it drops fromthe nipple ,14. l I l it will be understood that the passage of thewater from the cylinder through-the coupling 1 will heat the-oil to a. high state of (fluidity, enabling it to ,freely pass from the oil; cup through the nipple 15 and into thecyl- -inder.' As there is acontilnuous flow of this' 1., ,In an oil-cup,-the combination of a coupling having an oil-chamber therein, a water passage-way around said chamber, an-oil-receptac'le mounted on the coupiingo'ver. said chamberand communicating therewith, a tube passing through the receptacle and chamber having an opening which communisates with the oil-chambena valve in said tube to regulate the flow of oil, and apipe adapted to connect said water passage-Way in said coupling with the water-space around the cylinder of an engine.
- 2. Ina device for the purpose set forth, the combination of a pipe com municatihg with the water-space of acylinder', a coupling in said pipe having an oi l-chamber, and a. wator-space surrounding sa d chamber, through which water isadapted t flow, and with the opposite ends'of which said pipe isconnec'ted, an oil passage-Way connecting the oilchamber'in said coupling with the interior of said cylinder, a sight-feed glass in said pasrsage-way interposed between the coupling and cylinder,- and a valve controlling the communicating oil-passage between said cylinder and chamber.
3. The combination of a pipe adapted to communicate with the water-space of an explosive-engine cylinder, a coupling in said pipe having an oil-chamber therein around which the water is adapted to flow, an oil-re-- ceptacle mou nted upon the coupling and com- Imunicating withsai'd oil-chamber, means connecting the oil-chamber ofsaid coupling with the interior of said cylinder, anipple through which the oil is adapted to be discharged,
and means. for controlling the flow ofoil throughsaid nippl e. 1
4C. The, combination of a coupli'ng having an foil-chamber therein and passage for water around said chamber, an oil-cup mounted onthe coupling above-said chamber, a cap closing saidcup, atube depending fromsaid cap and screwinginto an aperture at the bottom of said oil-chamber, an oil-opening in the side of said tube, a nipple screwing into the under face of said coupling in alinemenfiwith said tube, a sight-feed glass around said nipple,'acasing'holding said glass in place and establishing communication between the nip-. pie and the interior or the cylinder, and a needle-valve passing through said'tube arid seating in said nipple.
In testimony whereof I sign this specifics tion in the presence of two witnesses.
