SPECIFICATION forming part of Letters'Patent No. 763,541, dated June 28, 1904.

Application filed May 22, 1903. Serial No. 158,308. (No model.)

To (bl/Z whom it may concern.-

Be it known that I, QUINGE CRANE, a citizen of the United States, and a resident of San Diego, in the county of San Diego and State of California, have invented a new and Improved Range, of which the following is a full, clear, and exact description.

This invention relates particularly to improvements in acombined range, baking-oven, and serving-table, an object being to provide a device of this character that shall be accessible from all sides and that will occupy but comparatively little space, adapting it for use in hotels or restaurants.

I will describe a range embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a section on the line 1 1 of Fig. 2 of a range embodying my invention. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a section on the line .3 30f Fig. 1, and Fig. 4 is a section on the line 4 4 of Fig. 1 and on an enlarged scale. h

Referring to the drawings, 5 designates a casing of sheet metal supported on standards 6, and connected to these standards are shelves 7, on which material to be kept warm may be placed. The casing 5 is divided longitudinally by a partition 8, having openings at intervals, the said openings being controlled by dampers 9 10, which have operating-rods 11 extended outward through a wall of the easing. When these dampers 9 10 are closed, it is obvious that the partition is practically continuous, and two fines and heating-chambers 12 13 are provided. The partition, however, does not extend entirely to the end of the easing, and therefore one flue communicates with the other, as clearly indicated in Fig. 2.

At each side of the partition the casing is provided with shallow ovens, here shown in the form of drawers 14, which are arranged with a space between their upper sides and the top of the casing and with a space below their lower sides and the bottom of the casing, so that products of combustion may pass above and under the ovens when desired. These shallow ovens 14 are designed for the making of toast, baking of pies, biscuits, or any rapid baking. I

Communicating with one end of the flue 12 is a fire-box 15, and from the ash-pit or from a point below the grate 16 an air-inlet flue 17 extends along the under side of the casing 5. The front of the fire-box will of course be provided with a suitable door or doors.

Arranged below each heating-chamber 12 and extended transversely of the casing is a damper 18, and similar dampers 19 are arranged above the ovens. By closing the upper dampers all of the heat may be caused to pass underneath the ovens, and obviously by closing the lower dampers and opening the upper ones the heat will pass over the ovens, while opening both dampers theheat will pass both above and below said ovens, and, further, by closing any pair ofupper and lower dampers and by opening one of the dampers 9 or 10 the heat will be short-circuited or cut off from a portion of the chamber. At the opposite side of the fire-box to that of the ovens 14 is a large baking-oven 20, arranged in a brick or other suitable shell 21 and spaced therefrom, so there is a free circulation of heat around the oven, the products of combustion finally passing out through the uptake 22. Spaces 23 between the oven 20 and the shell 21 communicate with one of the flues 18, and the communication is controlled by a damper 24, and a damper 25 is arranged between the fire-box and said flue 13.

In the operation when all of the dampers excepting the dampers 9, 10, and 25 are open the products of combustion will pass through the fine 12, back through the flue 13, and then around the oven 20 and out through the uptake 22. Should it be desired to use the oven 20 alone, the dampers 18 and 19 nearest the fire-box are to be closedin both fiues and the damper 25 opened.

The top of the casing 5 forms a table on which material to be served may be placed, and to prevent the material from becoming excessively heated I provide pads 26, of nonconducting material-such as asbestos, preferably sti'fiened by a core 27, of sheet metal.

To permit the passage of air underneath the pads and prevent excessive heating, I mount the pads on short legs 28, and these pads may be moved to any part of the casing or removed therefrom, if not desired for use.

A range made in accordance with my .invention will result in economy of space, time, and labor, also fuel, as floor-space is saved by discarding the ordinary serving-table, the work being done directly from the range, and labor is saved by removing the necessity of walking from a range to a table, or vice versa, and also in allowing waiters to dish up food, not depending entirely on cooks for all the serving. Fuel is saved, as complete control of heat is managed by a series of dampers in the fines, and a further economy in fuel results from the heating of the air in passing through the inlet 17 to the fire-box.

Having thus described my in vention,I claim as new and desire to secure by Letters Patent 1. A range, comprising a casing, a partition extended longitudinally therein and having openings at intervals, dampers for said openings, sliding ovens at each side of the partition, the said ovens being spaced from the top and bottom of the casing, a fire-box at one end of the casing, and dampers above and below said ovens at the sides toward the fire-box.

2. A range comprising a casing, a longitudinal partition in the casing having openings at intervals, dampers for said openings, a firebox at one end of the casing, an air-inlet flue leading underneath the casing and communieating with the fire-box, sliding ovens in the casing at each side of the partition, the said sliding ovens being spaced from the top and bottom of the casing, dampers extended tra-nsversely of the casing above and below said ovens at the sides toward the fire-box, and a baking-oven communicating with the casing.

3. A range comprising a casing, a partition extended longitudinally therein and having openings at intervals, dampers for said openings, ovens at each side of the partition, the said ovens being spaced from the top and bottom of the casing, a fire-box at one end of the casing, and dampers above and below said ovens at the sides toward the fire-box.

4. A range comprising a casing having a longitudinal partition provided with openings at intervals, dampers for said openings, the said partition forming two heating chambers and fines, a large even having communication withone of the flues, a damper for controlling said communication, a damperfor controlling communication between the fire-box and the flue communicating with said large oven, sliding ovens arranged in the casing at opposite sides of the partition, and means for controlling the passage of products of combustion along said ovens.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
