RICHARD SAVAGE, OF SAN FRANCISCO, CALIFORNIA.

HEATING AND COOKING RANGE.

SPECIFICATION forming part of Letters Patent No. 392,462, dated November 6, 1888.

Application filed February 23, 1887. Serial No. 228.58l.

To @ZZ whom it may concern:

Be it. known that I, RICHARD SAVAGE, of the city and county of San Francisco, State oi' California, have invented an Improvement in Heating and Cooking Ranges; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to a stove or range so constructed as to be employed for the ordinary purposes of cooking, and also to supply heated air, which may be conveyed to any desired point from'the range.

It consists of a base or cold-air chamber under the stove or range, into which pure air is received from beneath or outside the house, a Vlire-box, grate, and ash-pan of the usual or any suitablev construction, a top arranged in the usual manner for cooking, and an oven, and in combination with these of a series of lines and passages through whleh air is admitted and conducted around the heating lues or spaces to a suitable discharge,from which it is conveyed away.

It also consists in a means for lining or protecting the exterior plates, so as to red ucc the radiation of heat therefrom.

. Referring to the accompanying drawings for a more complete explanation of my invention, Figure l is a section taken through the lines a b of Fig. 2. Fig. 2 is a section taken through g h of Fig. 1. Fig. 3 is a section taken through c f of Fig. 2. Fig. 4 is a section taken through c l of Fig. 2. Fig. 5 is a detail of the joints.

In the ordinary construction of what are known as French ranges, walls lof brick surround the iire-place and oven, and the metal top is supported by these walls, cooking -being carriedou within the oven and upon the top of the range. In the ordinary cookingstove a similar iire-place, oven, and heat iues or passages are constructed, and there is a single outer wall of iron, through which a large portion ofthe heat of the stove is radiated into the room. My invention is designed to utilize this heat and economize it for the purpose of warming distant or adjacent rooms or halls. For this purpose I provide the stove or range with double walls and a series of heat-saving passages, together with inlet and outlet passages for the air.

A is the base-plate or bottom of the range (No model.)

or stove, and B B are side walls forming the exterior. C is the top. D is the iire-place having the usual lining of iron or hre-brick, E, and the grate F at the bottom; and G is the ash-pit. His the oren. These parts are similar in construction to those now in use.

' In the construction ofthe different parts of my stove or range I form channels, as shown plainly at a', Fig. 1, by raised flanges cast with the plates, and between which is a space of sufficient width to receive the edges of the side plates or the plates forming the oven or other part of the stove or range where it is desired to make a perfectly air-tight `joint, and this is more necessary in this case, as the smoke and products of combustion must be kept entirely out of the air-spaces. 'Ihe edges of the Various plates when they are put together enter the grooves or channels c', and are set in any suitable cement which will make a perfect joint.

In the construction of my stove or range the exterior walls, B, and top andbottom plate are enough larger than the portion needed for containing the fire-place, oven, and ordinary heat-passages to permit the surrounding passages or heat-saving spaces I, which are formed around the tire-place F and around the oven H, as shown. Beneath the bottom plate, A, ofthe range is a base, J, which is preferably made hollow, and has an air-inlet, K, opening into it at any suitable point. L are openings from this hollow base into the passages or chambers I, before described. These openings allow the air to pass upward from the base into the heating-spaces I, surrounding the ashpit and fire-place, and also surrounding the oven and the iire-llucs M, which pass around the oven. These lucs M are arranged in the usual manner, as plainly shown in Figs. 1 and 2,- so that the heat and products of combustion from the Iire-place I) pass above the oven, thence down behind it, thence beneath the bottom, diagonally toward the left lower corner, as shown in Fig. l, being directed to this point by a diaphragm or partition, which is shown in the dotted lines at N, and from this point the dame passes backward into the vertical passage M at the rear of the oven, rising and passing out at the pipe or chimney O. The heat `producing air passages I extend IOO around the sides et' the oven and exterior to the heat-producing spaces M, so that while the lient acts upon the oven in the usual manner it also acts through the outer walls to heat the air in the spaces I which surround. the oven. In order to still further increase this heating capacity the plate l), which extends upward between the heat passage )I and the air-passage I, as shown in Figs. 1 and I), is provided with a series of pins or equivalent projections, Q, which are cast in the plaie, so that one end ot' the pins extends into the heat and Haine passage M, while the other end extends into the air-passage I on the outer side. These pins or projections, becoming heated, will assist to heat the air which rises from the openings L in the base-plate and passes over the pins as it rises.

R R are vertical pipes standing within each space M at the rear end ot' the oven, and the lower ends of these pipes connect with the cold-air chamber J, beneath the base-plate of the stove, and the air which passes up through these pipes is delivered through the elbow at the upper end into the air-passage I at that end of the stove or range, and is mixed with the air which has already entered through the openings L in the base-plate.

ln order to prevent radiation from the exterior plates of the range a non-conducting lining, t, is iixed to them, as follows: These plates are cast with small wrought-iron pins projecting inwardly from them. I have found a very convenient way to place the ordinary French wirenails in the mold, and when the iron is poured in to form the plates it surrounds these pins and holds them firmly, the points projecting inwardly. I then take sheets of asbestus or other suitable non-conducting material and -iit it upon these plates. the ends of the nails passing through the sheets, so that thepoints maybe bent down upon the inside afterward and thus hold them firmly in place. This prevents almost entirely the radiation and escape of heat from the sides ot the stove or range. The top over the fire and oven is left exposed to the full force of the heat and lame from the iire-place and the Ilucs or pasY sages which extend beneath it, so that culinary vessels may employed upon the top ot' the range or stove in the usual manner for cooking. That portion of the box over the heatsaving dues or spaces is lined in the same manner as the ends and back to prevent loss of heat.

The hot-air outlet is shown in the present ease at S, Fig. 2. at the front of the stove or range, but it will be manifest that it may be taken out at any convenient point of the range to suit its position and the direction in which it is desired to carry the heated air. A pipe may be connected with this outlet and may be carried horizontally to a dining or other room or rooms upon the same floor with the range and to a considerable distance by making a sl ight risi ng inclination of the pipe as it passes away from the range, and branch pipes may be carried up through the walls to the upper rooms, which are conveniently located with reference to the kitchen, so that several rooms may be heated bythe surplus heat taken from the kitchen stove or range, andthe atmosphere of the kitchen will at the same time be much reduced and made more comfortable to the 0c cu pants.

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

A stove or range having a flat top for the reception of cooking-vessels, and a fire place or oven in the body of the range and below this top with the usual surrounding heating filles and passages, in coinbinatiouwith an exterior wall forming an air-inlet chamber beneath, and secondary passages I outside of the interior lieat-passages,with pins Q, projecting through the intermediate walls, l), from the heat-pas sages into the exterior ones, and ascries of vertical pipes or ilues, R R, passing through the rear heatpassages,i\[, and having their upper ends curved or bent, so as to discharge into the exterior surrounding passages,I, substantially as herein described.

In witness whereof I have hereunto set my hand.

RICHARD SAVAGE.
