IMPROVEMENT IN COAL-OIL STOVES.

Specification forming part of LettersPatent No. 129,436, dated July 16, 1872.

SPECIFICATION. I, JAMES H. THORP, of the State, county, and city of New York, have invented certain Improvements in Coal-Oil Stoves, of which the following is a specification:

Nature and Object of the Intention.

next to the rods to which the toothed wheels' are attached. These tubes have spaces between them to allow the toothed wheels to pass freely into the oil wick-tubes for the purpose of catching hold of the wick to raise or lower the same, as more or less heat is required in the stove. It not unfrequently happens that while the thumb-screws are being yturned to raise or lower the oil-wick on the old plan that the toothed wheels become entangled in the water-wick through which they pass, which forms an obstruction to the free adjustment of the raising and lowering device. This feature of my invention is intended to obviate this difficulty. The second part of my invention relates to the use of a metallic jacket surrounding the ues or chimneys through which the flames pass, and to prevent the escape of the heat and concentrate or utilize the same for cooking or heating purposes. This device consists of a band, cylindrical or of any other convenient shape, to rest upon the base of thelamp, and extend above the chimneys to form a rest for the stove 'iixtures, if desirable, for light work. When it is desirable to use the cooking untensils directly on the cylinder or cas-- while the cooking is going on, without the necessity of other light than that within the stove. My model shows mica in the ends of the chimneys only, whereas l desire to use the same in the sides also, if desirable. The third part of my invention relates to one or more openings in the top plate of the oilreservoir, to give vent to .the gases generated by heat from the lamp, and at the same time to serve as openings, into which a hook may be introduced to catch the oil-wicks in case they should by accident fall beyond reach of the toothed wheel intended to raise and lower the same. These openings are formed in the upper plate of the oil-reservoir, and are surrounded by boxes which have hinged covers that may remain closed, under ordinary circumstances, but should it be necessary to give vent to the oil-reservoir by opening them, the explosive vapor may pass ott' beyond the innuence of the iiame or heat from the lamp. The fourth part of my invention relates to the furnishing of an auxiliary lamp that may be moved around the stove to supply light to the same, so that the attendant may be enabled to attend to her work about thel stove at night without the aid of any other lamp. This device consists of an ordinary lamp with a metallic reservoir having one oi its sides made to conform to the contour of thestoves base to which it is loosely suspended. On this side of the lamp is iirinly xed a hook, extending vertically above its reservoir, which may be hung upon the flange forming the side of the watervessel. This lamp may be moved at pleasure about the axis of the stove by simply sliding it around the same on the iiange to which it is hooked. The auxiliary lamp is not unlike any other lamp used for illuminating purposes, with the exception that one of its Vsides (the sides of the oil-receptacle) is curved in amanner to conform to the curvature of the vessel about which it is intended to'move. Its hooks k, which attach it to the rim of the water-vessel, support it while it is being moved around said vessel or about the stove.

General Description.

A is the oil-reservoir, which is covered by the plate, which forms also the bottom of the water-vessel B, above the same. O C are the boxopenings, provided with hinged covers, which may be opened when it is necessary to recover the wick, which may by accident have slipped from the teeth of the raising and lowering device; or to allow the gas generated by overheating of the oil while the stove is in use to escape. The rims of the boxes covering these openings extend upward beyond reach of the water in the water-vessel. a a are the oilwicks, surrounded by the tubes Z l. These wicks are very wide, and are composed of any porous material, ibrous or textile, that would be influenced by capillary attraction. rllhese tubes have slots cut into them on one side to allow the toothed wheels b b b topass through and engage the oil-wick, which is to be lowered or raised to increase or diminish the flame. There are several of the toothed wheels arranged on rods which have attached to their ends thumb-screws, to be handled in lowering or raising the oil-wicks. The rods to which these wheels are attached have upright supports secured to the bottom of the water-vessel. On the side of the oil-wick tubes l, next to the raising and lowering device, are the series of tubes f surrounding the water-wicks, the same being open at their bottoms, so that said wicks may be under the iniluence of the water, as long as there is any found in the water-vessel. The arrangement of separate tubes is, as before stated, to allow free playvto the toothed wheels b b b, as they perform the work of lowering and raising the oil-wicks. Oii the other side of the oil-wicks the waterwick tubes are single, and of the ordinary form. A'

There is nothing claimed as new in the application of separate wicks surrounding the oil-wick tubes, as this device, in combination with the water in a vessel to cool the metal influenced by the heat of the lamp, is already before the public in several forms. My object is to arrange these wicks so that they may not be liable to entanglement with the raisingand lowering device, but to have them at the same time to answer the full purpose of the waterwck principle.

The metal disk N, with its spaces surrounding the points where combustion takes place, is ofthe usual form, and is supported by legs which rest on the bottom of the water-vessel. Chimneys D D, havin gtheirhorizontal sections of the oval form, and of a reduced size at their tops, are held in their places by a rod forming a screw-bolt passing between them vertically, the same being secured to the lower plate N and upper plate Gr. These chimneys D D have openings d d, which may be closed up when necessary by mica plates which slide vertically, as shown in Fig. 4 of drawing. E is a casing, of a cylindrical or other form, surrounding the chimneys D D, composed of metal or other material, with its inner surface polished. This cylinder is to confine and concentrate the heat when the stove is being used for baking or other purposes, when it is important to utilize the greatest amount of the same. This casing is supported on the plate N, and is kept in its place by small anges projecting from the upper surface of said plate. Openings e are left in this cylinder, as shown in Fig. 4, so that the blaze may be watched and regulated.. This casing may be dispensed with, if desirable, or adjusted at a momcnts notice, as it is not a fixed feature of the stove. H is a tube extending obliquely from the side of the oil-reservoir A, through which the oil is poured to supply thesame. The tube has a close-ttin g cap to exclude the dust, &c. I is the small lamp, hung to the rim of the watervessel by the hooks lo 7c, which keep it in its place as it is moved about the axis of the heater to give light around the same.
