ELlJAH J. CALDWELL, OF NEW YORK, N. Y., ASSIGNOR TO HIlllS'EL'F AND ALEXR. M. LESLEY, OF SAME PLACE.

IM PROVEM ENT-.IN GAS-STOVES.

Specification forming part of Letters Patent No. 49,469, dated August 1.5, 1865.

To all 'whom it may concern:

Be it known that I, ELTJAH J. CALDWELL, ot' the city, county, and State of New York, have invented certain new and useful Im prove- .ments in Gas-Stoves; and I do hereby declare the following to be a full, clear, and exact dcscription thereof, reference being had to the accompanying drawings, figures, and letters of reference making part ot' this specification.

Of the said drawings, Figure lis a top view` of my gas-stove. Fig. 2 is a vertical section, and Figs. 3 and 4 show parts in detail.

Similar letters ot' reference indicate like parts in all the drawings.

In the use of gas-stoves heretofore made, which have the tube open, much difliculty is experienced from the water boiling over and rusting out the sieve through which the gas passes, and also from the gas blowing downward when it is turned down.

My invention is designed to obviate theseV difficulties, and also to obtain better radiation and greater heat; and it consists in combining with the cylinder of a stove a tube provided with a sieve and perforations and aian ged top, as will be fully set forth hereinafter.

To enable others skilled in the art to make and use my invention, I will describe the construction `and operation thereof.

A represents the cylinder of a stove,1nade of sheet-iron, fitted to a perforated cast-iron base, B, and mounted 'by a cast top, C, the whole being secured together by bolts b b.

In the center of the base B is cast a cylinder, E, which projects upward, and upon which the tube F is connected by a frictionjoint.

To the bottom of the cast. bed is secured the supply-pipe D by means of al bolt, o,whicl1 pipe has a small hole, e, for the gas to pass up the cylinder F. In this tube F, 1 secure, by a frictionjoin t, d, a tine wire sieve, G, through which the gas passes. VThe upper part of the tube H is perforated, as shown at a a, around the cylinder and close up to the ange H. y

The operation will be as follows: Gas, being communicated by a rubber tube orsuitable` pipe, will pass through the pipe l) and up the, cylinder F, and as the bottom of the tube is open, a current of air passes up and is freely mixed with the gas. The gas passes through the pert'orat-ions a. a, where it is ignited, and

passes up around theiiangeH in a continuons sheet of tlame, and gives out a steady, power ful heat.

ven ts any accumulation of dirt or passage of boiling` water upon the sieve, which is the case where the cylinder is open at the top. The" `cylinder A, of the tube or cylinder F, sieve G,

and perforated'anged top H,oonstructed and operating together substantially as described,

and for the purposes specified. u
