WILLIAM R. RAMSEY, OF KENO, OREGON.

COFFEE-ROASTER.

SPECIFICATION forming part of Letters Patent No. 603,923, dated May 10, 1898.

Application filed May 29, 1897.

T at whom it may concern.-

Be it known that I, WILLIAM R. RAMSEY, of Keno, in the county of Klamath and State of Oregon, have invented a new and Improved Coffee-Roaster, of which the following is a full, clear, and exact description.

This invention is a device by means of which coffee may be effectually and conveniently roasted in a cooking stove or range of the usual construction.

The invention is also adapted for use in connection with the roasting of cereals.

This specification is the disclosure of one form of my invention, while the claim defines the actual scope of the conception.

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

Figure 1 is a perspective view of the invention in use in connection with a stove the door of which is hinged on a vertical pivot. Fig. 2 is a similar view of the invention in use in connection with a stove the door of which is hinged on a horizontal pilot. Fig. 3 is an end elevation of the device, partly in section. Fig. at is a section taken longitudinally through the device. Fig. 5 is an end elevation of the casing for the coffee-cylinder, showing the position of the cylinder with reference thereto; and Fig. 6 is an enlarged fragmentary perspective view illustrating the door of the stove shown in Fig. 1 as closed.

The roaster has a coffee-containing cylinder constructed with a foraminated body 7 and heads 8 and 9. The head8 is solid. The head 9 is provided with a feed-opening 10, which may be covered by a plate 11, pivoted to the head 9 and having at its free end an aperture 12, designed to receive a stud 13, fixed on the head 9. When the cover-plate 11 is moved to the closed position shown by dotted lines in Fig. 3, the stud 13 enters the aperture 12 and lies flush with the outer face of the plate. The parts are held in this position by means of a latch 14, pivoted to the head 9 and adapted to swing, as indicated by dotted and full lines in Fig. 3. Extending through the heads 8 and 9 is a shaft 15, one end of which projects slightly beyond the head 8 to form a trunnion therefor and the $erial No- 638,726. (No model.)

opposite end of which projects a greater distance beyond the head 9 and has a square terminal to removably receive the handle 16, whereby the shaft 15, and consequently the coffee-containing cylinder, may be turned.

The coffee-cylinder is contained within a rectangular receptacle 1?, one end of which has a bearing 18 for the end of the shaft 15 at the head 8, and the opposite end of the receptacle 17 has a downwardly, horizontally, and thence upwardly extended slot 19 to receive the portion of the shaft 15 adjacent to the head 9. The shaft 15 is moved through the slot 19 until it rests in the inner end thereof, as shown in Fig. 5. The shaft is provided with a fixed collar 20, arranged to lie within the receptacle 17 and to engage with the inner face of the end of the receptacle having the slot 19, whereby the coffee-containing cylinder is held against longitudinal displacement.

The cylinder is thus mounted to revolve freely within the receptacle 17.

In using the apparatus it is placed within the oven of a stove, so that the handle 16 of the shaft 15 will project beyond the stove. If the stove has a door, such as the door 21 in Figs. 1 and 6, which turns on a vertical pivot, the door of the stove should be provided with an opening 22 at its hinged edge, and the stove should be provided with an opening 25, registering with the opening 22, and through the openings the shaft 15 may project. This opening will not interfere with the swinging of the door 21 to an open or closed position, as will be seen upon reference to Figs. 1 and 2. If the stove has a door 23, asshown in Fig. 2, which turns on a horizontal pivot,-the door should be provided with an opening 2 1, similar to the opening 22 in Figs. 1 and 6 and registering with an opening 26 in the stove, and through these openings the shaft 15 may also extend.

The roaster may be used for roasting coffee or for roasting or popping corn and for all other analogous purposes. The perforated cylinder serves to permit an attendant to view the state of the contents of the cylinder and also serves to abrade the surface of the material roasted and remove therefrom chaff and husks. The chaff and husks dropping through the perforations of the cylinder or coffee-receptacle Will fall into and be retained by the receptacle 17, from which the chafi and husks may be removed when desired.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination of a rectangular receptacle, one end of which is provided with a hearing and the opposite end of which is provided with a downwardly horizontally and thence upwardly extending slot, the upwardly-extending portion of which forms a bearing alined with the bearing in the first-named end of the receptacle, a cylinder located within the receptacle, one head of the cylinder having an opening therein, a hingedly-mounted plate capable of swinging over said opening to close the same, a shaft run through the cylinder and mounted in the aforesaid bearings, the shaft being connected and disconnected with the receptacle through the medium of the slot in one head thereof, and a handle attached to the shaft whereby the shaft may be revolved.
