HYDROCARBON-BURNER.
SPECIFICATION forming part of Letters Patent No. 662,941, dated December 4, 1900.
Application filed May 25, 1898. Serial No. 681,681. (No model.)
To all whom it may concern:
Be itknown that I, WILLIAM R. JEAvoNs, a
V 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 Hydrocarbon-Burners; and I do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to hydrocarbon-burners; and the invention consists in the construction and combination of parts, substantially as shown and described, and particularly pointed out in the claims.
In the accompanying drawings, Figure l is a side elevation, partly in section, of a single burner and oil-supply and associated parts comprising my invention. Fig. 2 is a plan view of a section of the oil and vapor trough, including the oil-supply, as hereinafter fully described.
The present invention is of the kind in which the heavier hydrocarbons, such as kerosene, are used, and it is designed to accomplish several important objects, as will appear in a further description of the invention.
A represents the base of the burner, provided in this instance with a tubular pedestal a, supported and adapted to slide up and down on a fixed post B. A lever O has an eye over the post on which the base A rests, and this lever is fulcrumed at one end on uprights c and at the other end has a handle, and a ratchet-post D serves to engage the lever and hold it in any placed or adjusted position.
This is a simple form of mechanism for raising and lowering the burner-base, and it may be substituted by any equivalent or equal mechanism, the object in any event being to provide easy and simple means for lifting or lowering the burner in respect to the fixed oilsupply tank or reservoir D. A flexible pipe or tube E connects the base A and oil-supply tank E, and while I preferably use a light brass pipe for this purpose any other yielding metallic or other pipe, tube, or hose may be used, if preferred. By bending the pipesay as shown-all the flexibility I need is afforded in the bend. The tank D has a wellknown mechanism in its bottom for maintaining a substantially constant or fixed oil-level,
and a corresponding level will be maintained through pipe E in the base A, and the volume of oil passing into the base A may in a measure be regulated by adjusting the base in relation to the oil-level by means of lever O or its equivalent.
The base A is shown here as annular, though it may be oblong, and is formed with several distinctive features, including a trough 2, which for convenience of descrip tion may be regarded as that portion of the base below the two seats 3 and 4: for the perforated combustion -tubes G and H. Each seat 3 and 4 is shown as a shouldered ofiset in the base, and on the outer side of trough 2,
about half-way its depth, is an outwardlyset shoulder or ledge 5, which forms a seat or rest for a band-shaped non-combustible and capillary lighting-wick L. This wick or ring is preferably about the same thickness as the depth of its rest or seat 5, so that it leaves the bottom and sides of trough 2, except the portion covered by said ring, exposed directly to heat radiation from the combustion-chamber, and the ring extends upward from its seat pastseats 3 and 4, with its top practically on a plane with the lowest perforations of the combustion chamber. With this arrangement not only is the oil and vapor space in the trough exposed to direct heat radiation from the combustion chamber, but by means of the lever O the trough may be moved in such relation to the maintained oil-level that while oil may be maintained wholly around the bottom of the trough, yet the capillary ring will be above this oil and will have little or no influence on its vaporization. Oil is supplied to this ring and is carried by capillary action to its top edge, and as this top edge isin acertain definite relation to the flame at the lowest perforation 7 in the combustion-chamber it will be apparent that whether the oil-level is just sufficient to cover the base of the ring or at a higher point there is but slight difference in the conditions for vaporization, as in either case the oil is presented for vaporization at the top of the ring. When, however, the relation of the oil-level and trough is changed to raise the base of the ring just above the oil-level, oil is no longer presented at the top of the ring in close proximity to IOO Ltd
the flame, but is, in effect, presented on a considerably lower plane, and the direct result is a lessened rate of vaporization, with consequently somewhat lower flame.
In cases where the lighting-rings become defective and do not present oil for vaporization at all points alike and where the capillary ring is directly on the bottom of the trough and has no oil-space below it and the oil flow is sufficient only to reach part Way around the trough, and thus supplying oil only to one section of the ring, the flame is apt to be uneven and unsatisfactory. By leaving the vaporizing area below the ring, as described, uneven flame from these causes is avoided.
The trough 2 is deepest at the side where the oil enters, the'bottom of the trough being gradually inclined upward from the oil-inlet. By this construction and arrangement the raising or lowering of the trough causes the oil-surface to extend more or less around the burner and to cover a greater or less area in the bottom of the trough. Thus if the trough be raised in relation to the oil-level so that the oil is exposed over only a small area in the bottom of the trough a smaller measure of vaporization occurs than with the oil covering a larger area, and a relatively-lower flame results, and by moving the trough up or down any desired height of flame may be obtained. The inclined bottom of the trough also facilitates the extinguishing of the flame, as when the trough is wholly raised above the oil-level the oil more readily drains back into the feed-pipe.
It will be seen that the band-like capillary ring resting on the seat 5, as before described, and apart from the inner perforatedtube, leaves an annular vapor chamber or space adjacent to its inner side, this chamber eX- tending from the bottom of the trough to the lowest perforations in the inner tube and having a greater depth than width, these relative dimensions of the chamber or space I meaning certain capacity for the reception and movement of the vapor and presenting at its top to draft and flame influences but small area as compared with its carrying capacity. When the oil is vaporized at one side of the trough only, as occurs when a re duced flame is maintained, this chamber serves for protecting the vapor that it may distribute, by reason of its gravity, all around the burner in a manner now well known in this art. With quite low flame the oil for its maintenance may all be vaporized near or perhaps in the mouth of the feed pipe, and the ring being supported above the bottom of the trough at this point permits the free inflow of the oil or vapor from the feed-pipe to the vapor-chamber. To prevent the creeping of the oil from about the oil-inlet to the capillary ring, a recess is formed in the seat 5, as seen at 10, Fig. 2, and the ring spans the recessed portion as a bridge, with little or no contact with the walls. It will also be noticed that the base A has flanges 8 and 9 extending upward and outward from the tubeseats 3 and 4: and in a. sense continuing the trough proper of the base .111) to this level,
and in any event forming oil or vapor channels or chambers outside the combustiontubes to take care of any measure of oil or vapor escaping out of the burner at seats 3 and 4. No danger will come from presence of oil at these points, and the flanges are precautionary and desirable rather than essential to the ordinary operations of the burner. By thus flaring the flanges 8 and 9 outward, as shown and described, they aiford the desired security against overflow of oil or escape of vagrant vapor, but do not interfere with the proper inflow of air through the lower perforations 7 to the combustion-chamher.
It will be observed that the pipe E is inclined outwardly and downwardly from its connection wit-h base A, so that when said base is raised to extinguish the flame the oil will retreat from the portion of the pipe next to the burner, and thus avoid possible vaporization therein by reason of back-heating from the burner.
In starting the burner the burner-base is lowered by means of the lever O to bring the lighting-ring L to or beneath the oil-level,so that it may be ignited. The flame from this ring heats the burner parts,and soon the flame emerges from the top. of the combustionchamber, when the vapor generation becomes excessive, so that the vapor tends to pass up through or between the tubes without being sufticiently oxygenized, and thus produce a white flame. The consequence is that there is a lessened combustion within the chamber, and this acts to reduce the temperature, which furtherresults in a checking of such excessive vaporization. On the other hand, when the flame is about even with or somewhat below the top of the tubes the tubes become highly heated and tend to increase the vaporization of oil. It will thus be seen that burners of this class with unlimited oil-supply have inherent conditions incident to their operation for automatically maintaining a maximum flame.
In adjusting for a lowered flame the trough is raised to such position that the oil extends only partially over the bottom of the trough, and thus the oil is not only presented over a reduced vaporizing area, but at the same time the head of oil is decreased, rendering the flow into the burner more sluggishand of less volume.
