IMPROVEMENT 'IN COAL-OIL STOVES.

Specification forming part of Letters Patent No. 118,858,August 22, 1871; reissue No. 7,674, dated May 8, 1877; application filed April 7, 1877.

To all whom it may concern I It consists, further, in a chamber arranged Be it known that I, JOHN A. FREY, of between-the oil-reservoir and the airspace be- New York city, county of New York and State heath thecone-plate, iuclosing the wick wheels of New York, did invent certain new and useand shafts, and filled with cement or other ful Improvementsin Goal-Oil Stoves, for which nonconduc tor of heat, substantially as and Letters Patent No. 118,358 were issued to me for the purpose hereinafter set forth. upon the 22d day of August, 1871 which Let- It consists, further, in the combination of ters Patent having been found defective, in the wiclocones, chimney or combnstionchamthat the specification and claims do not cover her, and deflector, snbstantiz'tlly as and for the and embrace all of the original invention, as purpose hereinafter shown'and described. set forth in the application filed in the Pat- It consists, further, in the combination and cut Oifice on the 20th day of July, 1871. construction ,of the parts which compose the Now, therefore, being desirous of reissuing heating portion of my stove, substantially as said Letters Patent, herewith surrendered, I and for the purpose hereinafter specified.

' It consists, finally, in the stove as azvhole, its several parts being constructed and combined to operatein the" manner and, for the purpose substantially as hereinafter shown.

luthe annexed drawings, A represents the oil-reservoirof my stove, constructed preferably in a circular form, and having a vertical scription of the said invention, reference being had to the accompanying drawings, making a part of this specification, in which Figure l is a perspective view of my improve stove arranged for use. Fig. 2is a like view of the heating portion of the same,

the upwardextended side wall and the top of said reservoir, and is inclosed at its upper -sidc, except where a tube, 1), passes through its cover, and enables water to be placed within. Two wick-tubes, C, and an oil-supply tube,

a, pass vertically through said watercham-' her into said oil-reservoir.

The wick-tubes O are arranged at each sidc',

water-chamber, B. which is formed Ill part by pose the wick-tube. I Figs. 3 and 4 are, respectively, vertical central sections of Figs. 1 and 2, upon lines extenolng from front to rear. Fig. 5 is alike view upon line as :r of Fig. 3, and Fig. 6 is a horizontal section upon line z z' of Fig. 5.

Letters of like name and kind refer to like parts in each of the figures.

The design of my invention is to enable hydrocarbon oils to be employed for cooking purposes in aconvenient, safe, andeconomieal manner; and tothis end it cons1sts,principalshafts D,for raising and lowering wicks within said tubes. Around the latter, upon said wator-chamber, is formed a second.cha1nher,E;-- which incloses said wick wheels and shafts.

and is filled with a-suitable non-conductor of which surrounds the periphery of the coneplate, and, extending downward from the' edge of the same",,is contained within the vertical wall of the air-space that is formed beneath said cone-plate, substantially as and for the purpose hereinafter shown.

"It consists, further, in combining, with. the cone-plate, provided with a downward-projecting annular flange, and with the upwardprojecting flange or-side wall of the air-space, a hinge which connects said ,parts together, gsubst'antially as and for the purpose hereinat unspec heat, 0. Beside each Wick-tube G is provided a tube, 0, which extends through the cement chamber space above the latter and thevlnterior ot. the water-chamber B. A wick, c, placed within said tube 0, will cause water to pass from said chamber B, l'ipward along'said wick-tube,'and assistin p eventing thesame from becoming overheated.

Surrounding and secured in horizontal position upon the wick-tube O, at a point midway between their upper ends and the cementchamber {13, is a perforatedplate, F, which at its edge s provided with an upward-projecting flange, f, that has a height of about threefourths of an inch, and receives and incloses a correspondiugly-shaped fiange,'g, which'projects downward from a' plate, G, that is pro vided with a cone, g, for each wick-tube 0,

which cone is of ordinaryform, and operates in the usual manner, to deflect the currents of air toward its wick, and cause said'airto iin' pinge upon the flame produced by the 'buruing of the oil. i

The flange g eng'ages with the flaugef, and

insures the lateral position of the cone-plate and the parts attached. thereto.

Secured upon and extending upward from the outer. edge of' the cone-plate G is a cylinder, H, which has a height of about six inches, and is open at its upper end.

Within the cylinder H is placed a sheetmetal cone, I, which, as seen in Fig. 6, is, in horizontal section; square, with rounded corners, and at its base inclo'ses the cones g, and

, from thence to'thc upper end of saidoylinder H decreases somewhat in diameter..

Extending across the'upper end of the cone I, midway between and parallel with the cones g", is a V-shaped strip, 11', which operates as a deflector, and divides and turns outward in opposite directions the upward current of heated air from the burners.

The cone 1 operates as a shield to protect the cylinder H from the heat of the burners,

and to prevent the outward passage of heat, the air-space between said cone and cylinder operatingas a non-conductor of heat,

In order that the size of the flame of each wick may be known, so as to cnahle the largest quantity of heat to be produced without forming smoke, a mica window, h, is placed within one side of the cylinder H, and a similar window, i, within the same side of the cone 1.

As the cylinder H and its attachments (the I cone-plate G and cone I) must be removed.

eachtime the wicks are trimmed or lighted, I connect said cylinder to or with the stove, by means of a hinge, L, one leaf of which is fastened to the lower edge at one side of said cylinder, while the other leaf is secured to a' contiguous portion of the stove, by which means said-cylinder. may he turned" to one" side, as shown. by Fig. 2, without liability to the derangement of parts that would occur it said hinge was not employed.

The. device thus constructed operates as follows: The reservoir Arie filled with oil and the chamber 3 with water, after which the cylinder and caps are turned to one side, the wicks. lighted, and said parts turned back to v place.

The waterin the chamber B operates to prevent heat from being radiated or transacss I mitted downward to the oil reservoir, and thus renders impossible the most frequent cause of the explosions of oil -lamps and stoves, while the cerneutfilled chamber afi'ords equal protection to the wick-wheels and shafts, and,

in connection with said water, prevents the central and lower portions of the wick-tubes I from becoming snificiently heated to vaporize lllfi Oils 2 Articles to be cooked may be placed in suitable utensils over the upper end of thegyilinder, but in order that the heat may be app led to two or more vesseis at the same time, I place over the upper end of said cylinder one end of a horizontal hue, M, which, at its opposite end, isprovided with a vertical pipe or due, N, through which the heated products of combustion pass into the open air,

The due M forms a stove-top, and is provided with a number of pot-holes,'m, which have the usual form, and are inclosed, when not employed. for the reception of vessels, by means of ;lids or covers in. fine, opposite to the stove, is supported upon or by means of two legs, 9*.-

Having thus set firth the nature and merits of'my invention, what I claim as new is- 1. In combination with the coneplate G, a flange, g, which extends from the edge of said plate downward inside of the flange f, substantially as and for the purpose shown.

in combination with the cone-plate Gr, having a downward-projectingann ular flange, g, and with the upward-projecting flange f, that receives and contains said flange g, the hinge L, which is secured to and connects together saidparts, substantially as and for the purpose specified,

3. in a coal-oil stove, a chamber located between the cone-plate and oil-reservoir, ar' ranged to inciose the wich'wheels and their shafts, and filled with a non-conductor of heat, substantially as and for the purpose set forth.

The combination of the cone-plate G g, cylinder H, chimney or cone 1, and deflector i, substantially as and for the purpose shown and described. i

The oil-reservoir Al, water-chamber B, wick-tubes 0, wick-wheels, and shaft l), eeruent-chaniher E, perforated diaphragm F f, cone-platei g gflcylinder H, chimney-cone I, and. deflector a}, constructed and combined in the manner and for the purpose substantially as specified.

in combination withthe heat-producing mechanism described, the stovetop M, provided'with the pot-holes m, covers m, exit flue hi, and legs'fl, substantially, as and for the purpose showm v In testimony I the foregoing l have hereunto set my hand and seal this 31st day of March, A. 1557?.
