IMPROVEMENT IN APPARATUS FOR STIRRING IVIAL'I" IN THE KILN.

Speciiication forming part of Letters Patent No. 115,390, dated May 30, 1871.

To all fathom it may concern:

Be itknown that I, `iii/'Enzian Tonrrnn, of

Milwaukee, in the county of Milwaukee and i State of Wisconsin, have invented a new and Improved Malt-Rotator; and I` do' hereby declare that the following is a clear, full, and

y of section being indicated by the line a b, Fig.

2. Fig. 2 is an end elevation, partly in seetion, 'of the same. Fig. 3 is a detail top view "l of the roller-lock.

Similar letters of reference indicate corre- `This invention relates to a new apparatus for agitating and movin g maltwithin the kiln,

so as to dispense with the muscular labor heretofore required` for the `same purpose. The vapors arising from the malt are-unhealthy, and ,produce disease inthe workmen, `which is prevented by the use of an effective automatic agitator. The heat can, ina -kiln which is provided with an` agitator, be constantly kept at the most advantageous point, while heretofore it had to be let down, `in order toenable the t working` parties to turnthe malt. The malt thus treated will `befof better quality, as it can be more frequently and .thoroughly turned. Its treatment requires less fuel,and is completed in less time thanbefore. My invention consists in the application to the kiln of a trav- `eling roller, which carries ladles orprojecting scoops for agitating and turning the malt.

Ain the drawing .represents a malt-kiln of suitable sizeand shape. `At its sides are arranged, within the same, longitudinal horizontal rails c 0,.which serve as supports and guides for `boxes. d d, in `which the ends of a roller, I, are hung. Each box d is connected with the ends of a chain, B, which passes over a pulley on a transverseshaft "O, and over a frictionpulley e, atthe opposite end ofthe kiln. The is hung in a frame or ears at one end of the kiln, as shown; as it is revolved in either direction it will move the chains B B, and thereby cause the boxes d d to slide on the rails o and carry the roller along. To the roller A arehinged four, -more or less, curved plates, constituting ladles `D D', for taking up and turning the malt. These ladles are right-andleft, one-half being curved to one side and the other half to the other side. When the roller moves towardl the shaft G the ladles D will be in action and project from the roller, while the ladles D arefolded against the roller, as shown in Fig. 1. While the roller moves in the opposite direction the ladles D will proj ect, while the oth'ers fold against the shaft. Steel brushes E arc affixed to the ends of the ladles, to

properly sweep the bottom of the kiln. A

chain, F, deriving its motionA from a shaft, G, hung near the end of the kiln, passes over a toothed portion, f,of the roller, and tends to impart rotary motion to the same whenever the shaft G is revolved. The shaft G receives rotary motion in the desired direction by gearvworked by hand; but it can also be thrown out of gear by a T-shaped link, h, which is pivoted to an ear, i, `projecting from the end of the kiln. From one of the chains B project two ears, j j one of them strikes the shank of the T-link h whenever the roller has arrived atone endof the kiln, and throws the clutch out of action to prevent further motion in the same direction. At the end of the opposite movement the other ear j strikes the T-link with equal effect. By throwing off the chain F, which revolves the roller, the latter can be used for distributing the malt equally over the bottomof the kiln. For locking the roller so as to hold the lower ladle in the desired position, a locking-bolt, k, is pivoted to one of the boxes d and can be thrown into the roller, preventing it from turning. When the roller revolves and exposes it fully tothe heat.

Having thusdesoribed my inventiornolaim 3. The T-link h, combined with the clutch as new and desire to secure by Letters Patg and with the projecting ears j of the chain F, entsubstantially as herein shown and described.
