AUSTIN F. TEIGEN, OF HAGAN, MINNESOTA.

COFFEE-ROASTER.

SPECIFICATION forming part of Letters Patent No. 548,405, dated October 22, 1895.

Application filed April1,1895- Serial No. 544,075. (No model.)

To all whom it may concern.-

Be it known that I, AUSTIN F. TEIGEN, a resident of Hagan, in the county of Chippewa and State of Minnesota, have invented certain new and useful Improvements in Roasters; and I do hereby declare the following to be a 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.

My invention relates to an improvement in roasters, and more particularly to such as are adapted for domestic use in roasting coffee or peanuts, popping corn, or drying malt, the object of the invention being to produce a roaster which shall be simple in construction, durable, easy, and cheap to manufacture, adaptable to any stove by the use of which the material being treated will be prevented from becoming overheated and burned, which can be operated by unskilled persons, and which shall be efiectual in every respect in the performance of its functions.

With these objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of my improved roaster. Fig. 2 is an end view partly in section. Fig. 3 is a sectional view. Fig. 4 is a detail view.

A represents a plate or frame having an angular opening a for the accommodation of a drum or cylinder B, said plate or frame being intended to rest on the top of a stove over the opening therein and to prevent its displacement. It is provided on its under side with a series of legs b, adapted to project into the opening in the stove and bear against the wall thereof.

\Vhen the deviceis to be used on a gasolinestove, a detachable ring I) will be attached to the under side of the'plate or frame and held in place by the engagement of a flange b thereon with the legs 1). When the ring I) is to be removed, it will be slightly bent to disengage it from thelegs b. In the drawings I have shown the device as adapted for use over a round hole in the stove; but it is evident that the device maybe made larger and elongated in form to fit an elongated opening in the stove top.

'A series of flanges c c d cl are bent up from the plate or frameA (or these flanges maybe riveted to the plate or frame, if desired) and serve to brace said plate or frame' The diametrically-opposite flanges c c are made-with notches c, which formlbearings for a shaft e, passing through the cylinder or drum B. One end of the shaft 6 is screw-threaded and passes through a similarly-threaded perforation in a plate or block 6', secured to the inner face of one end of the drum, and the other end of the shaft extends a distance from the drum sufficient to clear the edge of the stove and is made with a crank arm e by which to rotatethe drum or cylinder. The ends of a yoke f are bent hook-shaped, and the free extremities of the arms of said yoke are pivotally connected with the flanges c c immediately under and in line with the bearings of the shaft 8 on said flanges. In the normal position of the yoke its arms rest at f on the shaft and the yoke is disposed in practically a horizontal position, so as to retain the shaft and cylinder in place while the device is being operated. The arms of the yoke are bent slightly upward at f, so as to prevent the cross-bar of the yoke from resting on the plate or frame A, but permitting it to rest on a knob or catch f on said plate or frame. The yoke f may also be used as a handle when it is desired to move the device to and from the stove.

One end of the drum or cylinder is made with an opening g, through which the material to be treated can be inserted or dis charged. This opening will be normally closed by means of a gate or cover It, having an opening near its inner end for the reception of a washer 713, on which it can turn, said washer being located on the shaft e, and the outer edge of said gate or'cover is made with a lip h adapted to overlap a flange 71. on the end of the drum or cylinder.

A spring locking-plated is placed on the shaft e and retained in place by means of a nut 2", one end of said plate resting on the gate or cover h and washer 72. and the other ICU end or edge resting on the end of the drum or cylinder, so as to be normally in line with lugs or stops 71 projecting from the gate, and thus retain the latter in its normal position. Vhere the stops k engage the edge of the lock-plate 2, the latter is bent outwardly slightly, so that when lateral pressure is applied to the gate the stops will be permitted to pass under said plate against the resilience offered by the latter. The gate or cover h is also provided with a knob or button 3'.

A lever is pivotally connected to one of the flanges c and lies normally parallel with the gate or cover h. Thelever 7c is made wide and fiat at its pivoted end and is provided with a flange 70, which normally rests on the plate or frame A and sustains said lever normally in the position shown in Fig. 1. The lever 70 is also provided witha projection 70, which when the lever is turned to a horizontal position, indicated by dotted lines in Fig. 4, will be disposed in the path of the knob or button j on the gate or cover h. When the lever 70 shall havebeen turned to the position just described and the drum rotated forwardly, the knob or buttonj will engage the projection k on said lever and prevent the further rotation of said gate or cover with the drum or cylinder, and thus the gate will be opened automatically without the necessity of removing the drum or cylinder from the frame and without removing the frame from the stove. While the lever in is in the horizontal position above described a backward rotation of the drum or cylinder will cause the button 7' to engage the other side of the projection 10 (said button having previously been permitted to pass said projection) and cause the gate or cover to be closed. The lever is will then be moved to its normal position, as shown in Fig. 1, and the rotation of the drum or cylinder will be continued until the roast-ing of its contents shall have been completed.

On the interior of the cylinder or drum B a series of longitudinal ribs Z are secured. During the rotation of the drum or cylinder the contents thereof will be lifted and then dropped, thus keeping the material under treatment properly agitated and prevented from burning, the ribs preventing any of the material from remaining at the hottest part of the drum a sufficient length of time to become injured by an excess of heat.

My improvements are very simple. in construction, cheap to manufacture, and are effectual in all respects in the performance of their functions.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a roaster, the combination with a frame and a revoluble cylinder or drum mounted therein and adapted to contain material to be roasted, of a ring removably attached to said frame, whereby to adapt the latter to a gasoline stove, substantially asset forth.

2. In a roaster, the combination with a frame, of a drum revolubly-mounted in said frame and having an opening in one end, a gate normally closing said opening, and means adapted to be set for opening and closing said gate without removing the drum from the frame, substantially as set forth.
