OIL-STOVE.

SPECIFICATION forming part of Letters Patent No. 488,957, dated December 27, 1892.

Application filed January 5, 1892. Serial No. 417,102. (No model.)

At top and bottom of these windows, inward turned horizontal flanges fit the curved edges of the chimneys, see Fig. 3. These openings m are closed by a swinging door R, suitably hinged to the end of the front plate and held by a permanent catch. The pintles S for these hinges, as well as the catch 8 for fastening the door, are shown as cast integral with the front plate M.

The door R is also of novel construction. It consists of two laterally-joined platesR R having openings through them corresponding to the windows m in the front plate and the openings in the chimney edges. Between these plates transparent panes T of mica or other suitable material are interposed, the three parts R R and T being held in proper relative position by the bolt and nut U. The eyes V of the door-hinges are formed by projections on the end of the door-plates R R with a semi-circular recess in each projection. These are brought together laterally to form vertical, circular eyes surrounding the rigid pintles S on the end of the upright stove-plate M, th us avoiding the expense of drilling them and making it impossible for the door to become detached without loosening or removing the bolt U. The free edge of the door has a rigid latch engaging the catch 3. The rear edge of the cone-plate L has a projecting tongue W which enters the elongated loop J of the intermediate rack or stand I, while the front of said plate is provided with a swinging latch Z pivoted in bearings in the edge of the cone plate and havinga lipz adapted to engage with the catch K protruding from the rack or stand I. This swinginglatch has a projecting part, as a lifter, to disengage it from the catch K; such lifter serving by its gravity to hold the parts normally engaged. When the latch is lifted by the operator the front part of the upper frame may be raised and the entire top of the stove detached from the base by withdrawing the tongue W from the loop J. The reverse movements again engage the parts.

The ready detachment of the top from the base is advantageous when it is necessary to trim the wicks, but is not necessary when lighting them, since by merely opening the door It a lighted match can be brought into contact with them,and the subsequent condition of the flame may be readily observed and regulated.

I claim as my invention:

1. In an oil stove, the tank A with its top or dome D, exterior wick tube E and internal flange or wall H, integral with said top, in combination with the wick-raising device F G mounted within the dome and adapted to press the wick up or down against said flange or wall, substantially as set forth.

2. In an oil stove, the cone-plate and topplate, with vertical chimneys having edgewise openings, in combination with the front plate having corresponding openings, and

with a door hinged on said front plate, provided with transparent panes, and adapted to close the windows or openings through said front plate, and transmit light through them, substantially as set forth.

3. In an oil stove, the cone-plate and top plate, with vertical chimneys having edgewise openings, and the front plate having corresponding openings and rigid pintles for the door hinges, in combination with the door, formed in two laterally-joined parts with panes of transparent material held between them, and with the hinge-eyes formed by semi-circular recesses in lateral projections on such joined parts, arranged to surround and inclose said rigid pintles, substantially as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 6th day of November, A. D. 1891.

CHARLES K. STINSON.
