SPECIFICATION forming part of Letters Patent No. 259,055, dated June 6, 1882.

'Application led February 14, 1882. (No model) To all whom it may concern:

Be it known that I,.JAMEs L. SHARP, of 'New York, iu the county aud State of New York,.have invented an Improved Oil-Stove, of which the following is a specification.

Figure lis a vertical central section through my improved oil-stove on the plane of the line c c, Fig. 2. Fig. 2 is a horizontal section of the saine on'the plane of the line 7c 7c, Fig. l.

1o Fig. 3 is a detail vertical section'ou the plane ot the line c lr, Fig. 2. Fig. 4 is a front view, partly in section, ofthe stove,'the line q q, Fig. 2, indicating lthe plane of section. Y'

This vinvention relates to certain improvet5 ments in the arrangement of the oil-reservoir of a coal-oil stove and ot the cover or covers for the same.

The first object of the invention is to so arrange the oil-reservoir in a coal-oil stove, with zo reference to currents of air that are allowed to pass over it, that the danger of overheating the oil will be altogether avoided. Another object is to facilitate the connection of the several parts ot' the stove, so as to'giveac'cess to f each for inspect-ion, cleaning, and repair, also to simplify the manner of feeding the stove with oil.

The invention consists iu a new arrangement of oil-chamber with reference to a hin ged cover,

3c air-chamber, and surrounding framing, and

with reference to the feed or supply tube, all as hereinafter more fully described. In the drawings, the letter A represents the main supporting-frame ot' my improved stove,

3 5 which may be of cast-iron or other suitable nua-A teral, and is preferably perforated and ornamented, as 'shown in Figs. 2 and 4. It may be of circular form, as shown, or more or less elongated, orangular, if necessary. In this frame 4o is suspended the oil-reservoir B, which is .a

bowl-shaped vessel, provided at three (more or less) points with radiallyprojectin g outer ears,

a, through which are passed boltsb, or equivalent pins or screws, that extend also through the upper flange, d, of the frame'A. Thus the bowl or reservoir Bis suspended within the frame A. In order to prevent heat fromV being jas shown in Figs. 1 and 4. cover is to protect the contents of the oilres the frame and the lug or ear a of the bowl,

as is clearly shown in Fig. 1.

The oil-reservoir B is open on top, as clearly shown in Figs. 1 and 4, and has atene side a projecting nozzle, f, which enters into a iiuelike extension, g, ofthe frame A, as shown in Fig. 1. The due-like extension g is closed on top by a swinging cover, h. When this cover 71J is swung aside, as indicated by dot-ted lines in Fig. 2, it opens the top of the iueg, and gives access, therefore, to the open end of the extension f of the oil-reservoir. Thus the oilreservoircan be filled at pleasure through these extensiousfand gwithout requiring the main body D of the stove to be turned aside.

I. am aware that it is not new to provide oil'- reservoirs with extensions through which they :may be fed; but I believe it to be quite new :to provide an oil-reservoir that is incased by a surrounding frame with au extc1ision,j', that side of the radins ot' the upperheating-chamber.

G is the cover of the oil-reservoir. This coveris of annular form, and preferably bulged, The object of this ervoir, and also to furnish a support for the drum that holds the wick-tubes and their op erating mechanism and the diaphragm above said drum. Beyond that and the parts o, p, Eand r, hereinafter referred to, the cover G has nothing to support, because the heating-druml D of the stove is supported by a frame, E, which is hin ged, at t', to the frame A, and which is further supported on the frame A by projecting legsj, which are more clearly shown in Figs. 3 and 4. Thus the cover C does not take part in supporting the drum D, or any of the l,attachments of said drum.

I regard this as quite an important feature, because it enables yme to secure the wick-tubes in the cover in the manner which I shall hereinafter describe, and for other obvious reasons. All strain is taken from the oil-reservoir B by my construc- 1 tion of'stove. The cover Chas at oneside a enters an extension, g,of the frame itself, outprojection or hinge-piece, 1,(see Figs. 2 and 4,)

that enters a slot in the flange of the frame A, and on which hinge-piece the said cover C can be swung up, as indicated by dotted lines in Fig. 4, after the drum` D has been swung on IOC its hinge i away from the top of the cover C. When the coverC is in its horizontal position it does not at any part rest on the reservoir B, but is entirely supported throughout by the frame A, and being bulged, as shown, and at no point in contact with the reservoir B, there is an air-chamber, fm, formed beneath the cover C, and above the oil-reservoir, which air-chamber communicates with the annular space n, that directly surrounds the reservoir B, and thence with the open air through the apertures ofthe frame A. The cover C, as before stated, is of annular form, and has in the construction shown upwardlyprojecting posts o, on which rests the ring p, which supports the perforated diaphragm F, that admits atmospheric air to the tiame or tiames of the stove. Between the cover C and the ringp is ample space to allow the air to reach the said diaphragm. The ring p is held fast by two (more or less) bolts, r, that extend from it downwardly through the cover C, or through inwardly-extending lugs of said cover, as shown in Fig. 4. rlhese bolts r are drawn tight until the ring p rests firmly on the supporting-posts o.

The wick-tubes G Gr are securely fastened in a sheet-metal drum, H, that has perforated walls s, and that rests on the cover U, the said sheet-metal drum H being `of such size as to close the opening in the top of the cover G. The drum H is held in place by the bolts 1', and furnishes a further protection for preventing the oil from being overheated, inasmuch as an air-chamber is formed within said drum H, and also because the air in said drum can always circulate through the perforated rim s. Beyond being secured to the said drinn H, the wick-tubes have no further rigid connection with the stove, and when it is desired to remove or repair them it is only necessary Ato lift oit' the cover C,nnscrew the bolts o', and

then have all the parts that are `joined t-o the cover C in the stove separated for cleaning or repair. Being secured to an air-box, H, the wich-tubes are not liable to communicate any heat to the oil-chamber, nor do they dip into the oil-chamber to such a depth as to be liable to come bodilyin contact with the oil itself, at least as far as the most perfect construction of the stove is concerned.

I have described the box H as being made of sheet metal; but of course it maybe made of any other suitable material.

The drum D, which forms the heating-chamber of the stove, has a door, I, at one side, said door containing a piece of mica, t, to allow the flame or flames to be seen without opening the drum.

I desire it to be understood that when I mention in this specification the wick-tubes77 I do not mean to limit myself to the use of more than one wick-tube in a stove, nor, in fact, to anynumber, as all the features of myinvention are applicable to stoves having single wicktubes, as well as to stoves having more than two wick-tubes; nor do I limit myself to any particular form of stove, which, as already stated, may be circular, oval, oblong, or even square.

I claim- 1. In a coal-oil stove, the combination of a supporting-frame, A, with a reservoir, B, suspended at two or more projecting points from said reservoir, and with non-conducting packing c between said projecting points and the supporting-frame, substantially as described.

2. The combination of the oil-reservoir B, having projecting nozzlef, with the surrounding supporting-trame A, having flue-like extension g, into which the said nozzle f enters, substantially as and for the purpose described.

3. The combination ofthe supporting-frame A,containing the suspended oil-vessel B, with the cover G, drum H, that holds the wick-tubes, and with the drum-frame E, which is hinged to the frame A, and entirely supported thereon, so that the drum and its attachments will not be supported on the cover C nor on the drum H, substantially as described.

4. The combination of the supporting-frame A with the suspended oil-reservoir B,and with the cover C, having projecting hinge-piece l, that enters a slot in the nangc of the frame A, and with the drum D,which is separately hinged to the frame A, so that by folding the drum D the cover C and the wick-tubes will be left undisturbed, substantially as specifled.

5. The combination of the frame A, having air openings or apertures, with the suspended reservoir B, and with the cover C, all arranged to form an air-space, m, between the cover and the reservoir, and a communicationm, between said air-spacem andthe outer air, substantially as specified.

6. In an oil-stove, the wick tube or tnbesG, carried by and fastened to a hollow drum, H, having perforated wall s and closed top and ICO bottom, in combination with the annular cover C and reservoirB,the drum H resting directly on and closing the opening in said cover, sub stantially as specified.

7. In an oil-stove, the combination of the annular cover C of the oilreservoir with the ring p, posts o, diaphragm F, wick-tubes G, hollow drum H, having perforated walls and closed top and bottom, and bolts I', substantially as described.
