CHARLES M. HOLLlNGSlVORTIl, OF CLEVELAND, OHIO.
OIL-FEEDING DEVICE FOR VAPOR-STOVES.
SPECIFICATION forming part of Letters Patent No. 443,765, dated December 30, 1890.
Application filed July 14, 1890. Serial No. 358,640. (No model.)
To all whom it may concern.-
Be it known that 1, CHARLES M. HOLLINGS- WORTH, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Oil-Feeding De vices for Vapor-Stoves, of which the following is a full, clear, and exact description, reference beinghad to the accompanying drawings, in which- Figure 1 is a side elevation of a vapor-stove containing my invention. Fig. 2 is a central vertical sectional view on line 2 2. Fig. 3 is a detached View of a part of the pipe 10, its outlet, and the drip-point; and Fig. 4 is a detached view of the pipe 7 and glass indicatortube 8.
My invention relates to vaporstoves in which the constancy and regularity of the burner-flame are dependent upon the regularity in the rate at which the liquid hydrocarbon is fed to the carburetor, and it is particularly adapted to and is shown in the drawings in connection with that form of vapor stove which contains in its construction the sort of gravity-carburetor which forms the subjectmatter of Letters Patent No. 121,834, granted to me February 18, 1890.
The object of the invention is to provide means for feeding the liquid hydrocarbon to the carburetor regularly and constantly at any desired rate, the ultimate purpose being to preserve a constant flame, whether large or small, at the burner.
\Vith these ends in View my invention consists in the construction, combination, and arrangement of the parts which are herein shown and described, and definitely pointed out in the claims.
I will now proceed to describe in detail the particular embodiment of the invention which the drawings show, although it is not my intention to limit my invention to these details further than distinctly expressed in the claims.
A suitable tank or main reservoir 1 is provided for containing the supply of liquid hydrocarbon to be vaporized, which reservoir is preferably made of sheet metal and in cylindrical form. A supplemental reservoir 2 in the form of a substantially L-shaped pipe is connected with the main reservoir by a duct 3, and the liquid hydrocarbon passes by gravity through said duct from the main to the supplemental reservoir. A valve 4 is adapted to close the duct 3. The precise construction and connection of this supplemental reservoir which the drawings show are as follows: A vertical leg 5 of this L-shaped pipe rises from the cross-coupling, into which it screws, to about the level of the top of the main reservoir. Its upper end is open and serves as a vent, through which air may freely pass in and out, thereby insuring a constant atmospheric pressure within the supplemental reservoir. The cross-coupling 6 is soldered to the side of the main reservoir, and in it is formed the duct 3 above referred to. The outer horizontal extension of the crosscoupling 6 is screw-threaded to form a bearing for the valve 4, which opens and closes the oil-duct 3. The vertical leg of the supplemental reservoir below the cross-coupling 6 consists of a lnetalic pipe '7, having screw-threaded ends and having an intermediate portion cut away for the purpose of exposing to view a glass tube 8, which is inserted within said pipe. A packing 13, of soap or any suitable substance, not affected by the liquid hydrocarbon, is placed around the endsof the glass tube to prevent leak-- age. One end of this metallic pipe 7 is screwed into the lower end of the cross-coupling 6, while the lower end of said pipe is screwed into an elbow 9. The other end of this elbowis connected with a pipe 10, which extends into the carburetor and is inclined upward slightly, as shown in Fig. 2, thus bringing its outlet 11 at or near the level of the lower part of the glass tube, which serves as an indicator. A drip-point 12 guides the drops issuing from the outlet 11 to the proper point above the evaporator contained in the carburetor 20. The carburetor shown is intended to be substantially like that shown in my prior patent, No. 241,834, above referred to. The outlet 11 is provided with a valve 14, screw-threaded into the open end of the pipe 10 and closing against a valve-seat in said pipe. The mechanism for operating this valve is located on the outside of the vaporizing-chamber and is constructed as follows: A disk or wheel 15 is pinned or otherwise secured to the valve-stem, so as to rotate with it. A lever 16 is slipped onto the valve-stem outside this disk and is held firmly against the disk by nut 17 on the end of the shaft, and thus this lever-arm may be adjusted to any desired position on the valve-stem. Iivoted to the side of the main reservoir is a hook-shaped stop 18, which falls by gravity into such a position that it engages with a pin 19 on the end of the lever 16 when the valve is being opened, and the lever is so adjusted upon the valve-stem that it will e11- gage with this pivoted stop when the valve is moved far enough away from its seat to permit the liquid hydrocarbon to flow at the rate ordinarily required to produce the proper feed to the burner. The hook-shaped stop may be moved upon its pivot out of reach of the lever whenever an indefinite backward movement of the valve is required for the purpose of allowing the escape from the out let of any obstructive particles which may have lodged therein.
Either the glass tube or that part of the metallic pipe close to said tube may be provided. with indicator-marks, by means of which an operator can easily determine any variations of the height of the liquid within said glass tube.
In operating this device the valve ll is turned back until the lever 16 engages with the stop 18, thus giving the required size to the drip-outlet. It is evident that the rate of discharge from that outlet will vary as the pressure upon it varies, and that the pressure upon it will vary with the height of oil in the supplemental reservoir above the level of said outlet. Thus the feed of oil to the carburetor may readily be brought to the particular rate required at any time by so adjusting the rate of flow from the main reservoir to the supplemental reservoir by means of the valve a as to bring the oil in the supplemental reservoir to and maintain it at the necessary level to give the desired rate of feed.
In preparing these stoves for the mark ct the lever 10 will generally be adjusted to such a point that when the valve is unscrewed until said lever strikes the stop a proper opening will be formed to produce a full feed at the burner when the proper level in the tube 8 is maintained. By this adjustment no especial skill or experience on the part of the user of the stove is required.
Having thus described my invention, what I claim as new, and desire to secure by Letters "atent, is
