COFFEE A ND PEANUT ROASTER.

SPECIFICATION forming part of Letters Patent No. 256,428, dated April 11, 1882.

Application med september 13,1881. (Model.)

' Be it known that I, CHARLES L. COLE, acitizen of the United States, residing at Bushnell, in the. county of McDonough and State of Illinois; have invented certain new and useful Improvements in Coffee and Peanut Roasters; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as. will enable others skilled in the art to which it appertains-to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 is a perspective of the entire device. Fig. 2 is avertical central section ofthe device as shown in Fig. l. Fig. 3 is a crosssection of that part of the device which contains the furnace and roaster. Fig. 4 is a detail of one of the strips inside the cylinder. Fig. 5 is a detail, showin'g the exitiue.

This invention belongs to that'class of devices known as coffee or peanut roasters; and Vthe distinguishing features or points of novelty i larly be set out and explained.

In the accompanying drawings, A denotes that part of the device which contains the t'urnace B and the roasting-cylinder C. This part is preferably of the shape ot' a parallelogram in horizontal cross-section, but is considerablyv higher than it is broad. The furnace 0r heatf ing-chamber B is constructed and 'finished in any desired way to insure the greatest amount of heat in the chamber about the roasting-cylinder, which is placed centrally lengthwise in the part A and above the furnace. Thiscylinder is made of sheet metal, and, while called volved, its ends being left open, itscontents.

will be discharged vinto said hopper'and then 5o tlow down through the vspout cinto any convenient receptacle. Around the under side of said cylinder is the semi-jacket F. This extends from end to end ofthe casing A, but is. of less diameter, and thus is allowed'a free space at each side ot' the cylinder C for the 55 upward flow of the heat and volatile products Ot' combustion from the furnace. This cylinder is hungon and revolved by means of shaft D, which is mounted in the strap d, projecting from one end of the casing A and in the wall 6o 0f the discharge-hopper at the other end. The

flanged heads c, at the ends of the cylinder, are outside ofthe end Walls of the structure A'. Across the middle of the cylinderandnear each end are the strips'c. centrally through them. In the head opposite the crank are hinged the semicircular doors c, which open outwardly, and are .properly v supplied with latches, so that they maybe opened or closed, as desired, to put intoor re- 7o move peanuts, coffee, &c.,'from the cylinder. These doors may also have sliding doors, it' desired. In the opposite head ot' the cylinder C is xcdcentrally the cone C. -In the head around the. edges of the coneare slots or open- 7 5 ings c3.

The annular door c, around the cone', is adapted to cover these. The crank D passes through the apex of the cone. Coffee or. peanuts may be fed into the cylinder C through the opening c5`in said co'ne while said cylinder 8o is in motion, so that its revolution need not be stopped for the purpose of supplying thema-V terial to be roasted. This opening should be provided with a suitable cover. By opening,

the annular door c1 the cylinder may be emp- 8 5 tied without stopping its revolution.

When at rest the cylinder C may be filled through the pipe G, which extends down from the dished shaped receptacle a in the top ofthe Structure A. By pulling outward the valve H a, extends entirely across the top of the chaml ber of combustion beneath the receptacle a.

The walls of' the structure A, in the space beroo v The axle D passes -65 The pipe Gr has will escape through the exit-pipe I. A damper, i, suitably controls this exit.

It' desired to throw some heat under the warmin g chamber or receptacle K, the damper i', which controls the passageway b between the furnace-chamber B and space L in the center horizontally of the structure K, may be opened. The volatile products ot combustion will escape t'rom this chamber through the pipe I', which extends from the upper front end of the heating-chamber under the exhibitor K and connects with the exit-pipe I.

The provision of the jacket or shield F beneath and extending somethin g more than onehalf around the cylinder C will prevent volatile products of combustion from escaping through the holes in tire-chamber B, out of which the ends of the cylinder protrude. The open space between its upper edges will afford ample room for the action of the heat reverberated from the top a of the chamber of combustion, and thus the action of the heat on the entire cylinder will be equalized.

Secured to the inside of the cylinder C is a double-inclined plane, M, set at right angles to the inside periphery, and on the edges of the double inclines are the lips m, which are bent at right angles tothe planes M, and these likewise at their inner edges, m', are bent so as to be parallel with M, so that conveyingtroughs are thus made having an openin g all along their length. There may be two ot' these inclined planes M on the inside of the cylinder. By means of these when the cylinder is rotated the contents, being by gravity greater on the lower side thereof, lodge against said doubleinclined planes and are carried up; but as they are carried upon said doubleinclined planes, the apex being in the middle lengthwise of said cylinder, they begin to slide down said double-inclined planes, one-half to each end, and then lodge against the lip m as the cylinder still revolves, and next slide toward the middle of said cylinder on the lip between the doubleinclined planes and the lip on the lip of said inclined planes. Thus at each revolution each double-inclined plane with the lips throws the contents tothe end of said cylinder and then to the middle. There are also secured to the inside of said cylinder, and alternating with said double inclines M, the single inclines N, extending from end to end of the cylinder, having a flange on their edges at right angles therewith, so that a section of said inclines will be T-shaped. Thus on-each side of said inclines N are formed channels, down or along which the contents are carried from end to end of the cylinder at each revolution thereof. By this construction is assured the most thorough and continuous stirring in all ways of each grain or nut ofthe contents. It is not enough that the grains or nuts shall be caused to slide and be pushed about as they are roasted, because even then', with the utmost care, they may sometimes be burned, but the several pieces must be picked up, turned over, and thrown in all ways to insure even, thorough, and perfect roasting.

, The peanut warmer and exhibitor K, which is preferably of the shape of a truncated pyramid, is permanently or detachably fixed in the upper part of the structure or casing O, which is attached in any suitable way to the side ofthe structure A. The roasted peanuts can be placed within it through the doors k in its top, and the condition ot' the contents can be observed through the glasscovered receptacle K in the four inclined faces from its top. The contents may be kept warm by means of water in the chamber k2 in the bottom, which will be heated by the circulation of hot air and the volatile products of combustion through the chamberL beneath it, or, when the damper i' is closed, by means ofa lamp or suitable heating agent placed in the base O. When such a heater is placed centrally under the opening o', which is controlled by the damper l, said damper being drawn out, the heater acts directly against the depending part 7c3 of the chamber k2 and eftectually raises the water to the desired degree of heat. It will be noticed that the water or steam chamber surrounds the base of the chamber K. To insure a flow of steam from the base into the upper part of k2, which comes about the interior sides of the part K, pipes k4 may be used. The chamber 7cIl may be filled with water by pipep, and this may also be used as an escape for the steam. It may be supplied with a cut-od', and also'have a whistle to indicate the state of steam in the waterchamber k2.

IOO

Thus is oil'ered in a combined and very compact device the entire apparatus for roasting peanuts and for keeping them in readiness in the best condition for use. The capacity ot' the roasting apparatus is so considerable that with a proper degree of heat and ordinary care a very great quantity of peanuts can be roast' ed, and with the very least per cent-of damage-indeed with almost none.

The means provided for heating the warmer to a proper temperature are such that all this is done without any considerable cost and in the easiest and most thorough manner.
