' Appncaion inea :rune 20,1892. Serin No. 437.336. No modelo To all whom it may concern.-

Be it known that I, AUGUSTINE C. WEST, 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 sufficiently 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 specification, in which Figure 1 is a front elevation of my improved oil-stove; Fig. 2 a central vertical longitudinal section of the same; Fig. 3 an end elevation; Fig. 4 a vertical transverse section enlarged of the lamp burner; Fig. 5 a side elevation partly broken away of the lighter sleeve detached; Fig. 6 a side elevation of the outer wick tube removed, and Fig. 7 sectional views illustrating the shelve hinges.

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

My invention relates especially to a construction of the body of an oil stove and the mechanism for furnishing heat for the same, the object being to greatly-decrease the cost While producing a device free from the objectionable features of sweating and heat-l ing of the oil tank and burner incident to the use of many stoves of this class.

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 burner mechanism considered as aowhole and B the stove. The stove comprises a horizontal wooden shelf, b, Supported on wooden legs, d. From each end of this wooden shelf a vertical standard of sheet metal, f, projects and supports the top, h, of the hot air box, C. This top has a series of the ordinary Stoveholes, g, and is preferably constructed of cast iron. The hot-box is completed by a bottom, c', which may be bolted centrally to the top at 100 (see Fig. 2) and by sides, 101, engaging said top. In the bottom, i, there are one or more openings, J, for the stove chimneys. Outside the boX the standards are connected by supporting bands, 102. The top projects longitudinally at, lc, beyond the standards,f, and at each side a hinged shelf, m, (see Figs. 3 and 7) is mounted. These shelves have a double hooked hinge-leaf, p, which is adapted to take in an opening, q, formed in the pendent flange, r, of the top,h. The hook, t, of the leaf is designed to support (see Fig. 7) said shelf when lowered as represented by dotted lines in Fig. 3. The4 shelf is supported in horizontal position by a notch, 0, at the opposite side of said leaf which takes on a projection, w, on the under side of the main top, h. The upper face of the wooden shelf, b, is coveredbya facing, fr, of sheet metal. The oil-tank or reservoir, D, is secured to the under face of said shelf supported by lugs, y. A filler opening and nipple, z, (Fig. 2) leads into the rear of the tank. The shelf, b, is provided with openings, 15, for the body of the burner mechanism. This body comprises an outer cylinder, 20, which is disposed in the opening, 15, of the shelf, b, and extends through the bottom of the reservoir, D. Near its lower end the body, 20, has a series of perforations or openings, 21, through which the oil flows. lhe Wick-tube, E, (see Fig. 4) comprises an outer tube, 22, and an inner tube, 24, secured to the outer tube by an annulus, 25. A ring, 104, connects the outer tube with the .cylinder, 20, said cylinder being soldered rlgidly into the bottom of the reservoir. The inner tube opens through the bottom of the tank. The outer tube is provided with perforations, 26, near its lower end while the innertube, 24, is solid. Said outer tube is shown 1n ldetail in Fig. 6. A wick-sleeve,27, comprismg a cylinder of perforated metal, is fitted to slide vertically between the tubes, 22, and, 24, the wick, 28, being secured to said sleeve. The outer tube, 22, is provided with a series of slotted openings,29, and journaled in said outer tube and the body,20, there is an ordinary wick-shaft, 30, bearing the pinion, 13, which meshes in the sleeve, 27, whereby said sleeve is moved to raise and lower the wick. The body, 20, is provided adjacent its upper end with an outwardly projecting bead, 31, upon which a cylindrical perforated air- 'distributen 32, rests, said distributor being ICO either fast or removable as preferred. An inwardly projecting bead, 33, is formed at the top of the body, 20, and an inwardly sloping annulus, 34, is mounted thereon, said annulus closely encircling the outer wicktube, 22, wit-hout touching leaving a narrow air-space, 105, which prevents heat being transmitted from the outer tube, 22, tothe body, 20, by said annulus. l The inner wicktube, 24, has an annular inwardly projecting bead, 35, which supports the flame spreader, F. Said spreader comprises a ring, 36, which rests on said a'nnulus and fits tightly into the inner tube. From the'upper edge of said ring an inverted cone of foraminous material, 37, is pendent, the apex, 38, of the cone `when in position being disposed centrally within the inner wick-tube. From the base of the cone outwardly Haring annular perforated walls, 39, project vertically, their top being covered by a solid disk, 40. Said disk is connected centrally by a rod, 4l, with the apex, 38, of the cone. y

rl"he chimney-holder, H, shown in detail in Fig. 5, comprises a combined lighter and insulator to prevent the heat from the chimney being conveyed to the body, 20, of the wicktubes, E. The holder comprises a cylinder, 50, of perforated material which is fitted to slide and rotate on\ the outer wick-tube, 22,`

above the annulus, 34, on the body, 20, said cylinder resting on the inner edge of said annulus, as best shown in Fig. 4. The cylinder is of such length that its top projects above the top of the distributer, 32. A horizontallyarranged ring or annulus of perforated material, 5l, is secured to the cylinder, 50, and when the holder is in position projects outward from the top of the distributer, 32, leaving a space, 52, between, as shown in Fig. 4. The walls of the cylinder, 50, are provided with one or more openings, 53, of size suitable to admit a match and in such position that when the holder or lighter is elevated these openings will register with the top of the wick as shown in the view of the heater at the right in Fig. l.

The holder proper, 55, is secured to the outer edge of the perforated annulus, 51. Said holder proper comprises a ring vertically curved so that its upper edge, 56, (see Fig. 4) projects slightly above the top of the outer wick-tube, 22, leaving a space, 57, between. The ring curves vertically downward forming a groove, 58, in which the chimney, J, rests. In the bottom of the groove a series of indentations' or bosses, 59, are punched, which rest on the annulus, 51, and by which the ring, 55, is secured to said fiange. This forms only slight points of contact between the solid ring, 55, of the holder and the perforated ring, 51, air-spaces, 60, being left between the bosses. The outer edge of the ring, 55, is bent vertically downward at, 6l, forming an annular ange which slightly overlaps without contacting the top of the perforated distributer, 32. A finger-piece or knob, 62, is

secured to the Vpendent flange, 61, whereby the chimney-holder may be rotated and elevated. The chimney, J, rests in the groove, 58, and projects through the opening, J, 1n the bottom of the hot-air box, C. Said ch1mneys are provided preferably with one glazed opening, 65, (see Fig. l) located opposlte the top of the wick. To light the wick by means of the finger-piece, 62, the chimney, H, may be rotated and elevated on the outer Wick tube, 22, until the lighter openings, 53, of its cylinder, 50, register with the wich-top and are exposed above the top of the distributer cylinder, 32. A lighted match may be 1nserted in said openings the wick ignited and the holder dropped to its normal positlon. By rotating the holder the chimney may be arranged so that its glazed opening will throw the light in any desired direction. One end wall of the box, C, and the standards, f, are provided with draft-openings, 70.

In use, the wick being lighted, the disk,

40, of the spreader, F,ldistends the tiame laterally. Cold air drawn by the heat of the iianie through the inner Wick tube, 24,passeS through the perforated cone, 37, of the spreader and out through the flaring perforated pol'- tion, 39, to the inner side of the flame,greatly intensifying the heat and promoting combustion. This construction of spreader also serves Vto so break u p the current of air through the innerwick or draft tube that the Tlie heat from the chimney, while sufficient to create a draft or current of air in the manner described, is prevented from heating either the cylindrical distributer, 32, or the body cylinder, 20, connected with the oil reservoir, by means of the air-space, 52. The perforated cylinder, 50, of the chimney holder and the perforated ring, 51, secured thereto also afford such air-spacethat heat cannot be imparted in any appreciable degree to the body, 20, or oil reservoir. The airspaces, 60, between the bosses in the bottom of the groove, 58, of said holder serve as additional means for effecting this result. It is found by thus constructing the burner and chimney holder that said burner is kept at a very low temperature even though the chimney and the holder-ring, 55, may have attained a high degree. of heat, it being possible practically to at any time handle the distributer, 32, while the wick is burning. The flame being fed by air on its inner and outer side disburses an intense heat to the box, C.

jections in oil-stoves of com mon construction, greatly cheapens the cost when employed as in my improvement and renders the stove lighter and stronger. Any number of holes, g, may be formed in the top, h, and only one burner may beemployed, if preferred. The hot-air box may be supported by single standardsat its corners instead of the broad sheet The hinged shelves, m, When lowered form a hot space around the chimneys greatly increasing the efficiency of the device for heating by radiation. It will be understood that a feed -Wick, 80, represented by section lines in Fig. 4, may be disposed around the outer Wick tube, 22, so that when the Wick28, becomes short it can be fed by means of said wick, 80, through the slots, 29, in the outer wick tube.
