APPARATUS FOR VAPORlZlNG LIQUID HYDROCARBONS AND SUPPLYING THE VAPOR T BURNERS.
SPECIFICATION forming part of Letters Patent No. 421,834, dated February 18, 1890.
Application filed November 12, 1888.
To 00% whom it may concern.- 7
Be it known that I, CHARLES M. HOLLINGS- WORTH, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Apparatus for Vaporizing Liquid Hydrocarbon and Supfollowing is a specification.
My invention relates to the process of vaporizing liquid hydrocarbon and supplying the vapor to a burner, wherein a suitable feed of the liquid is spread upon an evaporatingsurface freely exposed to the air within a vaporizing-chamber, and thereby vaporized as it is fed, and the mingled vapor and air are conveyed automatically to the burner by grav ity; and my object is to produce an apparatus of suitable construction for making application and use of this process in vapor-stoves and other allied appliances in which gasolinevapor may be used as fuel.
The apparatus comprises as essential parts an oil-reservoir, an oil-feed device, a vaporizing-chamber having an air-inlet and inclosing a suitable evaporating-surface, a conducting-tube, and a burner, to which may be added, if desired,'a valve to the burner. The form and construction of these parts and the manner inwhich I connect them together to constitute the working apparatus may be illustrated by reference to the accompanying Figure 1 is an isometrical representation of a vapor-stove embodying my invention; and
the oil-reservoir, with the oil-feed device in connection therewith shown entire, and of the and parts of two branch tubes, with an evaporator shown entire Within the vaporizingchamber and main tube.
As here represented, the oil-reservoir 3 is removably supported by Y a downward-projecting flange 4 upon the main walls 5 of the vaporizing-chamber, this flange and the bottom of the reservoir thus forming an upward extension and top or cover to said chamber. In this flange are located the air-inlets 6. By thus afiixing to the reservoir the upper portion of the wall of the vaporizing-chamber this part is put into fixed relation with the Serial No. 290,586. (No model.)
oil-feed device, apart of which enters within it, and it also serves as a supporting-foot to the reservoir when the reservoir is removed for filling; but, if desired, the oil-reservoir maybe placed at any distance away from the vaporizing-chamber and above its level, and the oil carried to the chamber by a suitable ipe. 6o
Attached to the reservoir is shown one form of oil-feed device that may be used, and which The vaporizing-chamber I prefer to make funnel-shaped, as shown, tapering to the size at its lower end of the conducting-pipe 26, to which it is joined, and by which it is supported. As will hereinafter appear, this con ducting-pipe-may itself be made to serve as a supplementary part of the vaporizing-chamber.
Greater simplicity of operation may be se cured by providing a separate vaporizing chamber and conducting-tube for each burner 8 5 of a stove having more thanone burner, in which case the oil may be conducted to the several vaporizing-chambers from the same reservoir by means of suitable pipes.
Within the vaporizing-chamber and removably supported from its walls in the manner shown is a sectional evaporator 33, 34, and 35, mainly of perforated metal plate, the sections made separable, if desired. The receiving and essential section 33 is in form a 5 broad hollow cone ending bluntly at the top in Y a horizontally=flattened drip-spot 36, the dripspot'being preferably imperforated. The oil will spread more evenly to all sides of the cone if azone around the drip-spot and forming the deflection from it to the sides of the cone is divided into a number of narrow channels or distributing-arms, as shown in the drawings. Raised points or ridges in place of the dividing-apertures shown would serve the same purpose. 7
In the composite or sectional evaporator shown in the drawings the receiving part 33 is represented as supported in place by contact with the funnel-shaped part 34; but the part may be used independently of the other parts shown, in which case it is preferably supported in place by contact of its base with the walls of the vaporizing-chamber, and these walls below the line of contact may then serve as supplementary evaporatingsu rfaces, to which the oil may spread.
By suitably shaping the vaporizing-chamber itself, as by inclining and flattening it, the inner surface of its walls may be used as the sole evaporating-surface, but not so efficiently as a special evaporator properly placed within the vaporizing-chamber.
The middle section 3st of the evaporator shown in the drawings is funnel-shaped, and receives and supports the upper section within its top. It tapers more rapidly than the walls of the vaporizingchamber, so that when it is placed in the vaporizingchamber it comes into supporting contact with the walls of the latter around its upper edge only. The draining oh. of this section of any oil that may reach its lower end is facilitated by so shaping the end as to give a termination in one or more points.
In order that the middle section 34. of the evaporator maybe the more readily placed and securely maintained in a concentric and vertical position within the vaporizing-chamber, a bead 37 maybe turned or ledge-formed around the walls of the latter where the two surfaces come in contact, and a flange turned on the edge of this section to rest on this bead or ledge. For like reason a bead may be turned around the middle section through the points of contact with it of the upper section.
Any additional evaporating-surface that may be required may conveniently be provided in the form of the third section 35. (Shown in the drawings.) This is a plain strip of perforated metal plate suspended from a V-shaped wire or loop 38, attached to the lower end of the part 34., and it may be made to extend any desired distance down the conducting pipe 26. For the two-burner arrangement here shown the lower end of this strip is beveled to give a drip-point at one side, so that any excess of oil that may drop from it, due to overfeed, will fall on one side only of the partition 31 shown, and follow the corresponding bran eh of the conducting-pipe to the vicinity of the burner which it supplies, and be vaporized by heat from the burner, the burner on that side being always used when only one is needed.
The evaporator and conducting-pipe operate as follows: As the oil drops onto the re ceiving top of the part 33 of the evaporator, it spreads downward over its surface, and is quickly vaporized and the vapor mixed with the surrounding air. The mixture of Vapor and air, being heavier than the external air, descends as it is formed through the conducting-pipe to the burners, the supply of air being constantly renewed through the air-inlet (i. Any oil that is not vaporized from the part 33 will be further exposed to the same air-current on the part 3i, while some portion of it may descend to the par-i235, and any final residuum of oil from the evaporator will, as already explained, run down one of the branch conducting-pipes to be vaporized by heat from the burner. By arranging and supporting the parts of the evaporator in the manner shown and described the oil in its downward course is prevented from coming into contact with the wall of the vaporizingchamber or of the main conducting-pipe, and any cleaning that may be required will be mainly confined to the removable evaporator.
In order that either burner may be used alone in the two-burner construction shown in connection with a single vaporizingchamber, each burner is provided with a rotating cut-off 50, inserted into the end of the branch conducting-tube on which the burner is placed. A cut-off or valve may also be desirable in some cases to close the outlet where each burner is supplied from a separate Va porizingchamber.
Having fully described my invention, what I claim, and desire to secure by Letters Pat ent, is
1. The combination, in a vapor stove or otherheatin g appliance, of an elevated vapor izing-chamber having an air-inlet at its upper part and an air and vapor outlet at its lower part, a suitable evaporatingsurface inclosed therein, an oila'eservoir above said chamber, an oil-feed device in connection with the reservoir, and a burner in communication with the outlet of the vaporizing-ehamber, substantially as set forth.
