MAL'IING APPARATUS.

To all whom it may concern:

Be 1t known that I, WILLIAM H. PRINZ,

a citizen of the United States, residing at (llhicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Malting Apparatus, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to apparatus for malting grain, and particularly to apparatus involving a rotary drum divided into a plurality of malt compartments, with means for supplying attemperated air to the grain in the compartments, which generically forms the subject matter of my application for patent of even date herewith, Serial Number 170,414. The apparatus described in my said application, specifically considered, involves the application of attemperated air to the grain in the malt compartments of a sectional perforated drum, by pressure, the air being introduced into the drum through conduits disposed axially in the malting compartments and passing out through the shell of the drum into the malting room.

My present invention has for its object to provide means for supplying attemperated air to the malt in a drum having the construction described in my said application,

by suction, instead of by pressure, so that the air enters the malting compartments through the perforations in the shell thereof, and thence passes through the malt from circumference to center. I accomplish this object as hereinafter described and as illustrated in the drawings.

What I regard as new is set forth in the claims.

In the drawings, Figure 1 is a longitudinal sectional view of the drum and the conduits connected therewith; Fig. 2 is a horizontal sectional View of the attemperator floor; and Fig. 3 is a horizontal sectional View of the malting room.

In my application of even date herewith, above referred to, I have described in detail the construction of my improved sectional drum; and therefore I deem it unnecessary to describe said drum specifically herein, except in so far as may be necessary to a full understanding of its general construction.

Referring to the drawings, A-B indicate the malting compartments of the drum, and C an intermediate compartment. The

Specification of Letters Patent.

Application filed August 22, 1903.

Patented May 2%, 1910. Serial no. 170,415.

malting compartments A-B are adapted to rotate in unison, being connected rigidly together by plates 1, connected with heads 23, respectively, at the inner ends of the drum sections forming the compartments 4 5 indicate the heads at the outer ends of the compartments A -B, respectively. The heads 2 8, 4-5 are imperforate, except at the axis of the drum. The heads 2-4 of the compartment A are joined by a perforated shell or casing 6, while the heads 8-5 of the compartment B are connected by a perforated shell or casing 7.

The heads 23 are connected by an imperforate shell or casing 8, which is nonrotary, being connected at its lower end to a flue or conduit 9 connected with an air tunnel l0.

1l-12 indicate perforated conduits ar ranged axially in the compartments AB, respectively, their ends being secured to the heads of their respective compartments.

13-14 indicate external extensions of the conduits 1l12, respectively, which extensions are joined to stationary conduits 15-- 16, respectively, which comn'iunicate through conduits 1718, respectively, with tunnels 1920, respectively. By this construction, by suction applied to the tunnels 1920, air within the compartments A-B may be exhausted through the conduits 1112; also, by suction applied to the tunnel 10, air in the compartments AB may be exhausted through compartment C. The conduits 9, l7 and 18 are provided with valves 2l-22-- 28, respectively, so that the flow of air through them may be regulated.

2 1- indicates a manhole through the casing 18, which is closed by a suitable cover. Similarly, the shells G-7 of the compartments AB are provided with suitable openings closed ordinarily by covers 2526.

21-28 indicate conveyers for conducting off the malt discharged from the drum. The drum is mounted upon suitable supporting rollers, not shown, carried by supports 29 30, respectively, shown in my application above referred to, and is driven by any suitable gearing, such as worms 81 and worm wheels 32, also fully described in my said application.

D indicates the malting room, in which a series of drums are arranged side by side, as shown in Fig. 3, said drums all being in communication with the

different tunnels

19, 10, 20.

E indicates the atteinperator room, and F a sectional attemperator therein, which is preferably of the construction described in my said application.

33 indicates a series of openings in the floor of the attemperator room, to aflord communication between said room and the malting room D. \Vhere the attemperator room is immediately above the malting room, the aassages 33 are simply holes cut in the floor, but they may be extended conduits, if necessary.

3-l indicates openings in the wall of the attemperator room for the admission of external air thereto. It will be observed that the attemperator F is between the openings 34 and the passages 33, so that air entering the attemperator room through the openings 3% must pass through the attemperator before entering the malting room through the passages 33.

G indicates what may be termed the exhaustroom, since it contains the fan 35 by which air is exhausted from the drums.

36-37 38 indicate flues affording communication between the room G and the

tunnels

20, 10, 19, respectively, as shown in Fig. 2.

l-l indicates the steep-tank room, which is preferably separated from the rooms EGr by partitions 39l0, respectively.

etl42i3 indicate valves in the flues 363T38, respectively. Said valves are of the ordinary butterfly type, and serve to regulate the flow of air through their respective flues.

It will be understood that the fan 35 discharges into the open air, its inlet end being connected with the exhaust room Gr. By this construction, by operating the fan 35, air is exhausted from the room GT, thereby creating suction through the flues 3637-38 and exhausting the air in

tunnels

19, 10, 20. The result is that air is exhausted from the compartments ABC, causing a flow of air into the compartments AB through the perforated walls thereof, the air entering the said compartments from the malting room, which continuously receives a supply of fresh air from the attemperator room through the passage 33. Since the suction is applied to the compartments A-B by means of the conduits 1112, which are con nected at both ends to the suction apparatus, it will be seen that suction is applied equally throughout the length of the malting compartments ih B and that the air flows in the same direction through the malt in the different compartments; consequently the grain therein is uniformly subjected to the action of the fresh air.

I wish it to be understood that my invention is not restricted to the specific details of the construction described, except in so far as they are particularly claimed.
