SZPECIFICATION forming part of LetterslPatent N o. 732,470, dated June 30, 1903.

Application filed February 17l 1899. Serial No. 705.916. (No model.)

To @ZZ whom it may concern.-

Be it known that I, HENRY B. TATHAM, Jr. a citizen of the United States, residing inV Philadelphia, Pennsylvania, have invented certain Improvements in Gas or Vapor Stoves, of which the following is a specification.

One object of my invention is to construct a gas or vapor stove of a cheap, simple, and safe character adapted for broiling,frying, baking, and boiling and in which the parts are always readily accessible, a further object being to so construct the broiling device as to prevent ignition of the melted grease or gravy. These objects I attain in the manner `hereinafter set forth, reference being had to the accompanying drawings, in which- Figure 1 is a view, partly in elevation and partly in section, of a gas cooking device constructed in accordance with my invention. Fig. 2 is a sectional plan view on the line 2 2,' Fig. l, showing the broiling device turned out of operative position. Fig. 3 is a side View, partly in section, of the stove constructed for the use of hydrocarbon vapor instead of gas as fuel and provided also with a turnspit attachment. Fig. 4 is a similar view illustrating another form of turn-spit'device. Fig. 5 is an enlarged section of part of the stove structure.

In Fig. 1 of the drawings, 1 represents the base of the stove, from which project upwardly two posts or standards'2 and 3,'each tubular as to its lower portionand communieating with a supply-pipe 4, locatedbeneath the base 1, this pipe receiving its supply ofi gas from any available source. The tubular lower portion of the standard 2 is provided with a cock 5, whereby the flow of gas through the same can be controlled, and this pipe communicates through a coupling 6' with a curved nozzle 6, which discharges into the open mouth of a coupling '7, the latter carrying the mixing-pipe 8 of the broiling device.

The broiler consists of an inverted cup 9, mounted upon the pipe 8 and upon a rod 10, secured to and projecting inwardly from the opposite standard 3, said inverted cup having at the bottom an outwardly-extending de- Iiector-plate 1l and immediately below the open mouth of the cup a spreader-plate 12, carried by a central threaded stem 13, which .is adapted toa threaded opening in the top The jet of gas from the nozzle-pipe 6 is projected forwardly through the coupling 7 and mixing-pipe 8 and induces a flow of air into and through said coupling-pipe, this mixture of air and gas being ignited as it issues from between the detlector-plate 11 and spreaderplate 12, so asgio form abroad flat annular sheet of flame beneath said deiector-plate, the products of combustion after passing out- Wardbeneath the defleetor-plate passing up around the edges of the same and out through the perforated or open top of the hood.

Mounted upon the top of the hood 14 is a grating or spider 15, upon which may be supported a frying-pan 16, which will thus be heated by the products of combustion passing upwardly through the perforated or open top of the hood 14, or any other Vessel which it is desired to heat may be mounted upon the open or perforated top of the hood 14 in place Yof the grate 15 and pan 16.

Slides 17, adjustabl-y mounted upon the upper portions of the standards 2 and 3, carry slotted bars 17a, which receive iianges projecting from Vthe opposite sides of a bakingpan 18, located above the broiling device and vprovided with a removable cover 19, this baking device being heated by the waste products of combustion from the broiling device and being adjusted vertically in respect to said broiler either by shifting the iiangesfrom one slot to another of the bars 17a or by adjusting the slides 17 vertically ou the standards 2 and 3.

Mounted so as to swing freely on the standard 3 is a sleeve 20, which is supported vertically upon a collar 21, the latter being movable up and down on the standard 3 and being secured after adjustment by means of a set-screw 22. The sleeve 20 has an outwardlyprojecting handle 23 and an inwardly-projecting portion with socket for the reception of a projecting pin 24 on abracket 25, which is secured to the broiling-pan, a similar ICO bracket at the opposite end of the pan having a projection which engages with a catch on a collar 26, vertically adjustable on the standard 2. The broiling-pan shown in Fig. l is double-walled, and consists of an outer pan 27 and an inner pan 28, the outer pan having at the top a ring 29, upon which rests the flanged top of the internal pan 28, which carries the meat to be broiled, the latter resting upon a grating 30, which is raised,by means of suitable feet, above a reliector-plate 3l. This plate, which by preference is inclined downwardly from the center to the edges, has short depending lugs or feet,where by it is supported ashort distance above the bottom of the pan 28, which is dished or inclined downwardly from the sides toward the center and has formed in the bottom radiating grooves 32, communicating with a central depending discharge-tube 33, which projects into a cup 34, centrally located on the bottom of the out-er pan 27. \Vhen,therefore, the meat upon the grate 30 is subjected to the heat of the flame above it, the melted grease will run down onto the plate 3l and from the edges of the same onto the grooved inclined bottom of the pan 28, from whence it will find its way into the discharge-tube 33 and cup 34, overflowing the latter and accumulating on the bottom of the outer pan 27. Thereis therefore no accumulation of melted grease in the pan 28, and hence nolikelihood of injury to the meat or danger to the attendant due to the ignition of such grease, the trapped lower end of the discharge-tube 33 effectually preventing the communication of any flame to the grease contained in the lower portion of the outer pan 27.

While the trapped escape-pipe is preferred, an open pipe may in some cases be used, or the bottom of the pan 28 may be perforated, the perforations being such that while the grease will pass through the same there will be no chance of ignition of the grease in the bottom of the outer pan, it being well known that ame will not pass through line perforations.

The plate 3l serves to reflect upwardly the heat from the burner above, and the use of the double pan 27 28 prevents loss of heat by radiation, this construction, therefore, enabling me to elect the broiling operation in less time than usual.

The vertical position of the broiling-pan in respect to the broiling device can be changed, as desired, by vertical adjustment of the collars 2l and 26 on the standards 3 and 2, respectively.

When the sleeve 2O is turned on the standard 3, the broiling-pan can be moved out from under the broiling device, so as to permit of the ready inserting, inspection, or removal of the meat, and tho inner pan 28 can be readily removed from the outer pan 27 and the latter from the sleeve 20 in order to permit of the removal of the grease or gravy from said pan 27 or for the proper cleansing of either pan.

The pin 24 may turn in the sleeve 20 and the latter may be incapable of rotating on the standard 3; but the construction shown is preferred.

The lower portion of the standard 3 may be tubular up to a lateral branch 35 and may communicate with the latter, a suit-able regulating-cock 36 controlling the flow of gas to said branch and the latter havinga burner 37 with projecting arms 38 for supporting a pot or kettle in which water is to be boiled.

As the frame of my improved gas cooking apparatus is composed mainly of pipe and fittings, it can be cheaply constructed. The structure is light and all parts of the device are readily accessible for cleansing purposes, whereas ordinary gas-stoves'have a heavy framework or casing independent of the gassupply pipes, and the parts of the stove are so inclosed that ready access to all parts of the same is impossible. Moreover, there is no chance for gas to accumulate in the oven, as in some gasstoves, and hence no risk of explosion as there is in such stoves when the oven-burner is lighted.

A stove constructed in accordance with my invention is available for the use of hydrocarbon Vapor as fuel, the stove shown in Fig. 3 being one of this character. In this stove the reservoir 40 is mounted beneath the base l, the hydrocarbon being pumped into this reservoir until the desired pressure is obtained or the pressure being applied by means of air pumped into the reservoir above the liquid contained therein-as, for instance, by means of a pump 40. The hydrocarbon escapes from the reservoir through the pipe 41, which extends up through one of the hollow standards of the frame and communicates with a hydrocarbon Vaporizer and mixer,consisting of a tube 42, communicating with the pipe 8 and having air-inlet perforations at the point where the hydrocarbon enters the same from the pipe 41 through an opening controlled by a needle-valve 43. Beneath the perforated portion of the tube 42 is a basin or tray 42, into which drips a small quantity of the liquid hydrocarbon, suicient when ignited to maintain the heat necessary to vaporiZe the hydrocarbon in the tube 42, so that a regulated flow of hydrocarbon vapor and air into the pipe 8a is provided, said pipe communicating with a hollow deilector l1, having in the bottom a central opening, beneath which is a spreader-plate 12, the construction resulting in the production of the broad, flat, blue flame, which is most eective in a burner intended for broiling purposes.

In Fig. 3 I have shown the combination of an automatic turn-spit 46 with the broilingpan, said spit being carried by bearings 47, which are vertically adjustable on the opposite slotted sides of the pan 48, which has in Loo IIC

the bottom a' trough or depression 49 for receiving the gravy. Hence by vertical adjustment of the spit 46 the fowl or other article of food which is being broiled can as it rotates be caused to dip into this trough and carry up the gravy therefrom, thus providing for the automatic basting of the fowl during the broiling operation. The pan 48 has a central depending spindle 50, which passes through a bearing in a swinging frame 51, projecting from the sleeve 20, the broilingpan being rotated during the cooking operation by means of a suitable motor 52, mounted on the arm 5l and driving the spindle 50 of the pan. This motor may be an electric motor, a spring-motor, or a motor of anyavailable character, that shown` for purposes of illustration being a spring-motor. The turnspit 46 has near one end a spur-pinion 53, which meshes with an annular :rack 54, carried by slides 55, mounted on the standards 2 and 3 of thestove, so as to be vertically adjustablethereon in order to correspond with the vertical adjustment of the broiling-pan and of the spit in respect to said pan. As the pan 48 is rotated, therefore, the spit will be carried around its own axis by reason of the engagement of the pinion 53 and rack 54,v the double turning movement thus imparted to the spit insuring the proper presentation of all parts of the fowl to the broiling device, so as to effect uniform cooking.

In the modified turn spit arrangement shown in Fig.4 the spit only turns upon its own axi's, being mounted in a frame or ring 56,10- lated above the broiling-pan and carried by vertically-adjustable sleeves 57 on the standards 2 and 3, one of these sleeves having a suitable motor 58 for rotating the'spit. If desired, the ring 56 may be made so as to slide up into the hood 14 telescopically.

The pipe structure of my improved stove may be made with gas-proof joints, so that it can be taken apart when it is desired to pack it into a small space for storage or transportation.

In order to increase the heat of the broiler, both of the supports 8 and 10 may be tubular, so that a supply of gas or vapor may be fed to the broiler through each of them.

Having thus described my invention, I claim and desire to secure by Letters Patentl. The combination in a gas or vaporheated broiling device, ofan upright standard or support, a broiling-pan mounted thereon, a downwardly-discharging burner supported above said pan and having a spreader-plate located below theburner-openingbutadjustable from and toward the same, and means for supplying a mixture of air vand gas or vapor to said burner, substantially as specified.
