VAPOR- SPECIFICATION forming part of Letters Application filed July 24:, 1900.
To all whom it may concern.-
Be it known that I, WILLIS MITCHELL, a citizen of the United States, residing at Malden, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Vapor-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to hydrocarbon-vapor burners forsteam-boilers and other places where quick and steady heat is required. It is especially intended for automobiles, although not by any means confined thereto.
The said invention consists in certain improvements in the burner and generator and in the means for supplying the same, heating them to start the automatic operation of the burner, and regulating the same.
The aforesaid improvements will be hereinafter more particularly set forth and claimed.
In the accompanying drawings, Figure 1 represents a vertical longitudinal section through the burner and auxiliary devices. Fig. 2 represents a detail plan view of the burner, partly broken away. Fig. 3 represents a section on line 3 3 of Fig. 1, showing the auxiliary burner; and Fig. 4 representsa detail perspective View of the jet-block. Fig. 5 represents a detail vertical sectional view of the inlet-tube closed by the screw-plug and the proximate part of the tank.
A designates the tank or receptacle for gasolene or other inflammable volatile liquid. This is supplied through an inlet-tube B of considerable diameter extending down through the top of the same a sufficient distanoe to insure an air and vapor space A of considerable dimensions above the surface of the liquid when the tank is fully charged. The upper end of this tube is flared out to form a bowl or cup B above the said tank. At the junction of this bowl to the cylindrical body of the tube an external annular flange or shoulder b is formed, which has a horizontal lower face resting on the top of said tank and a downwardly and outwardly beveled periph- COMPANY, on BOSTON,
BURNER.
Patent No. 681,833, dated September 3, 1901.
Serial No. 24,697. (No model.)
eral face adapted to be overlapped by a corresponding face of the inner edge of an annular fastening-plate C, whichis secured to the top of said tank by rivets c. The inner face of the said bowl at the junction of the said tube therewith is provided with an annular recess b, which receives a packing-ring 1). A doubly-bent air vent or passage e, having approximately the shape of the letter 2, extends through the Wall of said inlet-tube at its upper end. A continuation e of the Vertical part of this angular air vent or passage extends down through the wall of the said tube to the lower end thereof, and a valve E of rod or pin form is arranged in this extension so as to be movable up or down for closing or opening the said vent. This valve or rod is mounted on the free end of a spring G, which extends across the said tube, being attached at its other end to the bottom thereof. The said tubeis internally screw-threaded at b to receive the external screw-threads h of the stem of the screw-plug H, the top of which is expanded to form a cap resting upon the top of the said bowl B when the said screwplug is in its lower position. This screw-plug istubular, the upper end of its bore being enlarged and screw-threaded at h for the attachment of a coupling through which air may be forced into the interior of the said tank. The lower part of the said bore is also enlarged, forming an elongated chamber h within which works a valve in the form of an open box containing cork packing 2' and normally forced by a spring I, which surrounds the stem I of said valve, against the material of the said plug at the top of the said chamber h so as to prevent the inflow of air. A screw J, having a central bore to receive loosely the stem af0resaid,engages with internal screw-threads at the lower end of the stem of the said screw-plug and serves to adjust the resistance of the said spring by being screwed up or down more or less. When air is forced in, overcoming the resistance of the said valve and spring, it passes down through the annular space between the valvestem and the wall of the bore of the adjusting-screw. At the upper end of the enlargement or chamber k of the bore a lateral vent e is formed through the wall of the; hollow stem of the screw-plug, the same beingar-v ranged to register with the Vent e aforesaid when the said plug is turned down to its lowest position. At the same time the lower end of the stem of the said plug bears against the spring 0 and forces it down, withdrawing the pin or valve E from the vertical part of the vent or passage e, so as to open the same and allow the exit of air through the apertures ee into the bore of the screw-plug, from which it may escape when air is not forced into the said bore and the valve therein is not wholly closed. On the under side of the head'or cap of the said screw-plug is formed an annular bead H", arranged to be forced into the annular' packing hereinbefore described and spread-the same, so as to make a tight joint between the plug and the inlet-tube. In case the screw-plug should not be turned quite homethe joint may not be quite air-tight or liquid-tight, and it becomes important to prevent the leakage of liquid through the same. Insu'ch circumstances the vent 6 will allow theair and vapor of theupper chamberA to escapefromthe said' tank, thereby relieving the-pressure on'the liquid gasolene to a sufficient extent to prevent the latter from being At one endforced up through the saidjoint. of thesaid tank a gasolene-tube K extends fromthe lower partthereof to a filter-box M, containing suitable filtering material an, whence two supply-pipesM M extend to the two lower ends ofa-continuous pipewound in concentric helices to form a tubular generator N; A- tube L for supplying air and 'gasolene-vapor-is similarly connected with an annular perforated tubular burner O, which surrounds the said generator anddirects the blaze from its perforations against'the cylindricaloutercasing-N thereof. This burner is used-merely for starting the self-supplying action of themain burner, hereinafter described, and I therefore denominate it the auxiliary burner. It is supported by: rigid arms-or brackets .O froma rigid frame P, on which-the main burner Q. rests. The vertical cylindrical'body of; this burner Q extends down within the said generator, forming ahollow core therefor; From said body, at the upper end, extend radial communicating tubular arms Q, each of which is provided on its-upper side with a series of perforations q,
through which it discharges flame against aboiler. oranything else which it may be designed to heat. These tubular arms are of any. convenient number, eight of them being I shown-in Fig. 2 of the drawings arranged after the fashion ofstar-rays. aforesaid is-fastened at the top by screws n to these tubes or-rays. At its bottom the said casing has an annular trough or receptacle formedwithand around it for the reception of alcohol, which maybe usedas an alternativemeans for heating the'generator and starting the automatic action of the main burner in case the auxiliary burner should sage W.
The casing N fail to work satisfactorily or it is thought best for any reason to leave said auxiliary burner out of use. The pipe L is provided with a cock Z, whereby communication between the air and vapor chamber A and said auxiliary burner may be cut off when this choice is made.
The upper end of a jet-block R is fitted into the lower end of the tubular body of burner Q. This block is provided with a vertical central bore 1', terminating in a jet-hole 1", also with a transverse communicating pas- The said bore receives a needlevalve S, which wholly or partly closes at will the passage through the said jet-hole. The ends of the said transverse passage receive the lower end ofthe inner helix of the gen erator of which the jet-block thus becomes in effect a continuation, discharging solely through the said jet-hole. The downwardlyextendi-ng stem of the said jet-block is ex-' ternally screw-threaded to receive an internally-screw-threaded stuffing-box T, which is provided in its lower part with packing material t, fitting into the concave lower end'of the said jet-block stem. The said stuffing box has a central perforation i for the passage of the said needle-valve, also a tubular downward extension T which is open at its lower end and internally screw-threaded to receive a screw U, the stem of which is hol low, though contracted at the upper end, to allow the passage of the stem of a needlevalve, while retaining its globular head. A-
rod V fits removably from below into the hollow of this stem'and is removably held there by a screw- W, engaging threads in the lower end of the latter. The disk U, which forms the head of the said screw U, is removable therefrom and fastened thereon by a clamping-screw 2. When this screw is turnedin 'one direction, it draws out the needle-valve,
opening moreor less the jet-hole'aforesaid.
When turned in the other-direction, it forcesin the said'valve with the reverse thread. As the stem of the needle-valve is cylindrical and as the openings of the par-ts in contact therewith are cylindrical also,- the valves motion is longitudinal only. When it is to be removedfor any reason, the screw W and rod V are first taken out, and it then easily falls through. Thisavoids all risk offriction in removal and allows the screw U to remain in place. The aforesaid stuffing-box passes through a crossbar or plate X, which is attached to or forms part of the frame aforesaid and braces said box, the hole in said'bar being only large enough to conveniently admit the same.
The operation of the generator, burner, and
connecting parts is substantially the same as in my application for patent on a vapor-burninglamp filed May 17, 1900, Serial No. 17,056.
I do not herein claim the details of construction of the filling plug and tank, the same being covered by my application, Serial No. 33,008, filed October 13, 1900.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In combination with a hydrocarbon- 5 burner having radial perforated arms and a downwardly extending cylindrical part, a coiled tubular generator of cylindrical form surrounding the said cylindrical part, a supplernentaryannular burner surrounding the I said generator for heating the same, a tank or reservoir for liquid hydrocarbon provided with a space at the top for air and hydrocarbon vapor, a pipe from the said tank supply ing said generator with liquid fuel, and a pipe from the said air and vapor space supplying the said supplementary burner substantially as set forth.
