OIL-STOVE.

SPECIFICATION forming part of Letters Patent No. 411,406, dated September 17, 1889.

Serial No. 304,662. (No model.)

To all whom, it may concern.'

Be it known that I, AUGUSTINE C. VEST, of Cambridge, in the county of Middlesex, State of Massachusetts, have invented certain new and useful Improvements in Oil-Stoves, of which the following is a description sufiiciently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this speciiication, in which- Figure 1 is a front elevation of my improved stove, a portion of the hot-air chamber being broken away; Fig.2, a horizontal section on line no o in Fig. 1; Fig. 3, an enlarged vertical transverse section of one of the lamps removed; Fig. 4, an enlarged elevation of the air-distributing cones detached; Fig. 5, an elevation of the chimneydiolder removed, and Fig. G views illustrating certain details of construction.

Like letters and figures of reference indicate corresponding parts in the different iigures of the drawings.

My invention relates to that class of oilstoves in which portable lamps are employed; and it consists in certain novel features, as hereinafter fully set forth and claimed, the object being to produce a simpler, cheaper, an'd more effective device of this character than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.

In the drawings, A represents the body or frame of the stove, and B C D the lamps.

The body consists of a lamp-stand b, supported by legs d, to the top of which is a plate f, provided with circular stove holes or openings g, closed by detachable covers in the usual manner. The holes g open into a hotair chamber E, secured to the under side of the plate f.

The lamps B C D consist of a circular body h, having a concave bottoni i, an annular stiffening-iiange j being secured within said body around the edge of said bottom. The body h is extended below the bottom i, and is provided withV a series of air-holes Z near its lower edge. A vertical wick-tube l-I, open at both ends, is secured centrally in the bottom e', and is provided on its outer face with a spiral iiange or thread m. A lint p, adapted to travel on the thread fm, is disposed on said wick-tube. A sleeve q is fitted to slide over the tube ll, and is sufficiently large to admit the wick K between it and said tube, the lower end of the wick being secured to the nut p. A vertical rod r connects the sleeve q with the nut p, so that said nut will revolve as the sleeve is turned and slide vertically on said rod. Awater-cup L is depressed centrally at t, to enter the mouth o of the lamp-body h, in which it is fitted to revolve. The wicksleeve q passes centrally through the watercup and is secured thereto, said cup forming a rosette by which said sleeve may be rotated. A chimney-holder M is adapted to slide over the wick-sleeve q by means of a vertical sleeve zu, and extend into the depression t of the water-cup. The holder is provided with air-openings fy, disposed above the water-line in the cup L when in position. The bottom of the holder is perforated at ,e to admit water from the cup L into t-he body thereof. An annular groove 15, near the mouth of the holder, is iitted to receive and support the chimney P, which is provided with a door 16, having a transparent panel 17. A hollow conc R has its walls perforated with air-holes 18, its base 19 consisting of a solid plate. A smaller cone T has its base 20 secured centrally to the apex of the cone R, the walls and base of said cone T being perforated at 21, as shown in Fig. et.

Around the base 2O of the cone T is secured a guide-ring 22, which is fitted to slide in the wiclt-tube H. A stiffening-rod 23 passes from the center of the base 19 of the cone R to the apex of the cone T. The cones R T are detachably disposed inthe wick-tube H in an inverted position, as shown in Fig. 3. The base of the cone R, being larger in diameter than said tube, is thus disposed at a considerable distance from the mouth thereof and above the upper edge of the wick K. Openings 25 are formed in the bottom of the hot-air chamber E, through which the chimneys P project when the lamps are in position on the stand d, as shown in Fig. l. Detachable disks 26 IOO aredisposed around the chimney-tops to close said openings. Detachable caps 27, fitted to enter the chimney-tops, serve to prevent the cold air from passing into the chamber E from the perforations 'y in the chimney-holders of the lamps not in use.

One of the stove-openings g is enlarged to receive a water ring or tank 29, (see Fig. 6)

. which rests on the stove-top by means of a flange 30. An annular flange or rabbet-Bl is formed in the inner side of .the ring to receive the ordinary stove-cover. Two nipples 32 open into 'the tanks 29, to which flexible tubing may be attached leading to a supplytank, whereby acirculation of hot water may be maintained in said supply-tank. A barred or slotted stove-cover 33 is employed in one ofthe stove-openings to create a draft through the chimneys and hot-air chambers when the remaining openings are closed by cooking utensils or the solid covers.

A filling-tube 34:, provided with ascrewecap 35, opens into each lampebody.

In the use of my improvement the lamps are placed in position on the stand CZ with their chimneys projecting into the hot-air chamber E, as described. By revolving the cup L and thereby causing the nut p to move upward on the wick-tube H, the wick K may 3o loe adjusted at the proper height above said tube. The chimney may be removed Ato ignite the wick, or it may be lighted through the door 16. The base 19 of the cone R, projecting above the tube I-I, causes the flame to be expanded beyond the diameter of said tube, thus producing a larger heating and lighting surface and rendering the combusti( n. much more perfect. A current of air passes through the openings Z in the body and into the Wick-tube I-I. From thence it passes into the perforated cones, by which it is broken up or restrained, so that it is delivered gradually to the flame through the cone perforations above the wick-tube, thus supplying a light, even current to the inner side fiame,

which is thereby rendered steady and prevented flaring or smoking. The cup L is filled with water, which passes through the perforations e' into the chimney-holder M. The heat froln the wick-sleeve q evaporates the water in said holder, and the steam or vapor arising is conduct-ed to and consumed in the flame, which is found to be greatly intensified and enriched thereby. The tops of the chimneys P not in use in the hot-air chamber are closed by the caps 27, as described.

It will readily be seen that the water in the ring or tank 29 will be heated by the lamps, and being connected with an exterior watertank by pipes secured to its nipples 32, as set forth, a continual supply of hot water may thus beobtained.

When it is not desired to employ the waterring29, it may readily be removed from the stove-opening, and an ordinary rabbeted filling-ring disposed therein for receiving the stove-cover. It will also be seen thatthe perforations y in the chimney-holder afford a direct draft below and outside the flame.

Having thus explained my invention, what I claim is* 1. In a lamp for oil-stoves, provided with a water-cup, a hollow chimney-holder fitted to slide on the wick-sleeve and rest in the watercup, said holder being perforated at or near its bottom and also above the water-line of said cup, substantially as and for the purpose set forth.
