IMPROVEMENT IN LAUNDRY-STOVES.

Specication forming part of Letters yPatent N o'. 142,259, dated August 26, 1873; application led February 24, 1873.

To all whom it may concern:

Be it known that I, JAMEs H. MITCHELL, of San Francisco city and county, State of California, have invented an Improved Laundry- Stove 5 and I do hereby declare the following description and accompanying drawings are sufficient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention or improvement without further invention or experiment.

My invention relates to that class of stoves which are used for laundry purposes, and also by candy manufacturers for boiling sugar, and for like purposes. The object of my improvement is to concentrate the heat from the replace against the top ot' the stove, so that the greatest possible benefit can be derived from it before allowing it to escape up the stovepipe. In order to more fully illustrate and explain my invention, reference is had to the accompanying drawing forming a part of this specification, and which is a perspective view of my stove with the top removed, but its proper position indicatedy by dotted lines, being partially broken away.

A represents a stove of the class above named. lIhe hre-place inside of this stove is constructed of soap-stone, or other fire-resisting material, and is made in the form ot' an open-topped box, B, which is smaller than the outside iron shell of the stove, so that a space, e, will be left entirely around it between its outside and the outer shell of the stove. The grate C is placed in the bottom of the box B, in the usual manner. The sides of the box B slope outwardly toward the top, and extend upward to within a short distance of the top of the stove-shell A, inside, when the back and rear half of the two sides are extended outward at a greater angle, as shown at j' f, so as to meet the upper edges of the sides of the shell A, thus leaving an opening, c', on each side at the front of the stove, through which the products of combustion will pass on their Way to the draft pipe, which communicates with the space between the box B and stoveshell at the back of the stove. (Not shown in the drawing, but itspo'sition indicated by dotted lines.)

By constructing the stove with only the two side openings at the upper front of the stove, through which the products of combustion must pass, all of the heat will necessarily strike the top ot the stove before passing into the space or jacket between the box and shell, thus obtaining the4 greatest possible benefit from the heat.

The bent tube b Zn is the ordinary water-pipe usually placed in stovesot different constructions.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

rlhe stove A, having the sloping lire-box B smaller than the stove shell, and provided with the flaring back and sides ff, so as to provide a jacket or space, c, between the two, when the only communication with said jacket or space is through side openings t t', substantially as and for the purpose above described.

In witness whereof I hereunto set my hand and seal.
