.ELECTRIC COFFEE AND PEANUT ROASTER.

Application led June 5,

To all whom 'it may concern Be it known that 1, MARK T.. SEYMOUR, a citizen Vof the United States, residing at the village of Stowe, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Electric Coffee and Peanut Roasters, of which the following, taken in connection with the accompanying drawings, is a speciication.

The invention relates to roasters for peanuts, coffee, popcorn and similar articles, for which it is desired to provide a uniform and easily controlled heat, the present construction being an improvement upon the construction shown in my former Letters Patent No. 1,334,876; and the improvement consists in providing a at zigzag resistance element embedded in noncombustible cement, as for example asbestos cement, around a woven wire or perforate sheet metal rotatably mounted cage within which the article to be roasted is placed, the heating element and outer casing remaining stationary, While the cylindrical cage -or .Screen chamber is rotatably mounted within said stationary casing and heating element in .very much the same manner as the entire casinggand heating element were mounted in my former roaster, means being provided for Ventilating the interior of the roaster and controlling the heat therein; and the invention consists in the novel features and combinations hereinafter" set forth and claimed. v

In the drawings, Figure 1 is a perspective view of the roaster showing the cylindrical outer casing and heating element partially broken away to reveal said heating element and the cylindrical wire cage and their relation to one another. Lj'F ig. 2 is a perspective view of the cylindrical heating element ment. Fig. 3 is a lengthwise sectional view of the roaster at line 3-3 in Fig. 4 showing the construction and arrangement of the same, and the electrical connection to said heating element. Fig. 4 is a crosswlse sectional view at line 4 4 in Fig. 3 showing the arrangement of the different parts. Fig. 5 is an elevation of the eXit end for the` roasted article showing the exit and ventilating openings therein, two of the upper door s being shown in the open Vposition to permit the escape of the steam. Fig. 6 is a symbol of an adjustable transformer showing five specification of Letters Patent. PatentedJ une 14., 1921.,

steps from 110 .to 120; and Fig. 7 shows a six-point knife switch for the control of the heat in the roaster in combination with said adjustable transformer.

Like characters of reference refer to corresponding parts in the several views.

lThe numeral 10 designates the table or support for the electric roaster- 11, which table -is preferably provided with suitable legs 12 to give said table and the roaster 11 the proper angle of inclination, the telescoping leg parts 13 and 14 being provided with a set screw 15 so that the length of each leg 12 can be quickly and easily adjusted.

A motor 16 is provided on the table. 10 which is connected by suitable shaft 17 and gearing to the main supporting shaft 18 for rotatably mounting the inner cage or screen cylinder 19, which shaft 18 is mounted in suitable journals A2O and 21 on standards 22, and 23 supported on the table 10. The motor 16 is connected by wire 24 to a push switch 25 for-starting and stopping'said motor 16.

The roaster 11 consists of the stationary casing 26 which has an outer sheet metal cylinder supported on the bases 27 within whiclris a heavy asbestos lining 28 around a non-combustible cement cylinder 29 in which is embedded the electrical heating element 30. The heating element 30 consists of the two metal rings 31 and 32 at the opposite ends thereof which are connected by the spaced zigzag wires 33, electrical connection being provided to said heating element by means of the wires` 34. The cylinder formed by the spaced zigzag wires 33 and rings 31 and 32 fits within the asbestos or non-combustible lining 28 and is embedded in non-combustible cement 29 so that when the electrical current is turned on to said heating element, the entire mass of noncombustible cement 29 is given an even heat which provides the' required even heat around the cylinder throughout its length for roasting or baking the coffee, peanuts and similar articles within the rotatably mounted cage 19 within said cement cylinder 29 and heating element.

The roasting cylinder 11 is preferably of suiiicientlength to give the required amount of roasting surface for the coffee, peanuts and other articles so that as the rotation of the cylindrical wire cage 19 causes the coffee or other articles to slowly gra-vitate down the inclined surface of said cage, said article will be given the required amount i cylinder should be sufficient to permit speeding up of theroasting process, thereby giv- 1n exiigts 35 on the lower side preferably have the closure doors 36 to confine the heat within the roaster for certain articles, and two upper Ventilating openings 37 are provided with similar doors 38 to act as steam exits, all of said doors having hooks and eyelets so that they may be attached in position to close the openings 35 and 37 or to remain open for Ventilating the interior of the roaster.

A' single control push switch 25 starts the motor. Thel six-point knife switch 41 controls the degree of heat in the heating element 30 as desired through the adjustable transformer 42 shown in Fig. 6, which knife switch 41 and adjustable transformer 42 are connected to :the heating element 3() through the wires 34. The adjustable transformer 42 is preferably shown with 'five steps upward. Any number of steps with any desired arrangement of the length of Said steps upward may be arranged in connection with said adjustable transformer without departingl from my invention. It is apparent that this arrangement of electrical control through the transformer 42 and knife switch 41 gives substantially any heat desired according to the needs in roasting the different articles. Thus, for example, a heavy fresh grown coffee wouldy need a 'different heat from a Idry, well-seasoned codec.

The ends of the stationary casing of the roaster 11 may be either closed or opened as desired, and the coffee, peanuts or other articles are'fed in from the hopper 39 to the rotatably mounted cage 19 the spout 40 from said hopper 39 extending' only to the end of said cage so as to permit the free rotation of the saine.l The present arrangement greatly simplifies the construction of the roaster and gives a strong, even heat within the same, which heat is retained in the cement 29 .for a considerable length of time ,after the electric current is shut off.

I claim as new:
