TO ALL'WHOM I-T MAY OONCEN Be it known that I, GEORGE O. SANDERSON, of Boston, in the county of Suifolk, and State of Massachu setts, haue invented an mprovement in (looking Stoves; and I do hereby declare that the following is a full and exact description thereof. reference being had to `the aeeomp'anyipg drawings and to the letters of reference marked thereon w i i Nature. The nature of my invention consists in the construction and arrangement of the parts. of a cooking stove or range so that the stove may be used for burning solid fuel or gas.

To enable others skill'ed in the art to make anduse my invention Iwill proeeed to describe its ,construction -and use.

, Drawz'ngs.

Figure 1 represents a perspective view of'the stove complete, with the fuel grate removed and the gas pipes inserted. f

Figure 2 is a'longitudinal yertical section of the same.

Figure 3 is a front elevation of theisarnel- Figure 4 is a plan of the same.

Figure 5 is a full-sized drawing, representing in elevation the stop-cool: for turning on the gas, and-also the arrangement for mixing atmospheric air with the gas. For the purpose of enhancing its heating power the position of thelstop-cock and mixing arrangement is indicated by H, figs. 1, 2, and 3. i

A A, figs. 1, 2, 3, and 4, represent a wood, coal, or peat cooking stove, made in any of the ordinary forms, but here represented with the grate for solid fuel removed and' pipes for gas inserted in its place. N represents the main supply pipe for admission of gas tothe stove. To this pipe N is attached the pipe O by suitable eouplings. i To the upper end of the pipe 0 the horizontal pipe M is attached, from which the pipes lP' P lead to the pot holes B B', fig. 1, and also the pipes E E', leading to the -rear pot holes v O. The upper or discharge ends of these pipes are fiattened, as shown in figs. 2 and 4, so thatthe mixed gas and air can only escape through a narrow slit, formed by the fiattened end of the pipe. The ends of the pipes are flattened, as above described, so that the flame shall not follow the gas down into the pipes. At H H, in all these pipes, the stop-cool: and mixer represented in fig. 5 are inserted, The stop-tock H, fig. 5; is made in the ordinary manner. Thegas enters the mixer through the small orifiee represented by the dotted. line Q, fig. 5, and passes by'the openings R R up intp the pipe Pl; at the same time vthe atmospherie air enters the openings R R, and thus the two become mixed in the pipe P'. The front ,pot holes are provided with shallow basins BB', through the hottom of which the gas pipes 'P' P' enter.. The rear pot holes are providedwith rings or short eylinders reaching from the top of thestove to thetop of the oven. Into the sides of these cylinders the 'gaspipes E E' enter. The products of combustionare taken from B B', through .the pipes F F, to the real' pot holes C O, from which they escape through the opening shown in the lower part of thecylinder D D, figs. 1 and 2. The object of the shallow basiiis B'B' and the shortl cylinders 'C Cis to eoniine the heat of the blazing gas innnediatcly to the vesscl resting upon the pot holes. The'oven is heated by a series of pipes G G, figs. 1, 2, and 3, all of which are supplied with the stopcocl and mixer represented in fig. 5.V

' Use. w To use solid fuelvin my stove, all of the gas pipes are unscrewed from each other and laid away for future use. The opehings through which the ends of the pipes G G pass are protected by a thin metal slide. The grate is inserted, resting upon the'bar I, figs. 1 and 3. The shallow basins B B' and the short cylin'ders D D are removed, and the stove is now ready for solid fuel. To prepare the stove for gas the grate is to be reinovell` and the pipes reinserted. The shallow basins B B"and D D are placed in the pot-holes and the store becomes a gas burner.

The advantages that I claim formy store are that it may be changed from a solid fuel burner to a gas burner, or l'z'cc corsa, by a few inomeuts' work.

Olaz'm. What I claim as my invention, :Lud desire to secure by .Tietters Patent, is

1. The combination :Lnd :Lrrangement of the pipes G G with the oven L, substnntiilly as described and for the purpose set forth.

2. The combination of the basins B B' with the pot hoies of the cooking stove, shbstantially as deseribed and foi` 'the purpose set forth. V

3. The combination of the short oylinders D D with the root pot holes and the top of the even, sub` stantially as described and for the purpose set forth.
