Application filed April 9, 1903. Serial No. 151,720.

To all, whom it ILi/(Tbf/ concern.-

Be it known that I, ROBERT A. KIRKPAT- RICK, a citizen of the United States, and a resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Ventilating Malt-House Compartments; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention has for its object to perfect the ventilation of malt-house compartments; and it consists in what is hereinafter particularly set forth, with reference to the accompanying drawings, and subsequently claimed.

Figure 1 of the drawings is a diagram illustrating a horizontal section of a portion of a malt-house on the plane indicated by line 1 l in the second figu re, the perforated false bottom or malt-floor in this view being for the most part broken away; and Fig. 2 is another diagram illustrating a vertical section of a fragment of the malt-house transversely of its compartments.

Referring by letter to the drawings, A indicates one of a series of attemperating-chambers in a malt-house, this chamber being provided with beds B, of coke or other suitable air-filtering material, on perforated floors C over spaces that are open to a horizontal airduct D, in which water is sprayed from pipes E within a cage F, of woven wire or other suitable material, supported on inner ledges of said duct. The bottom of the air-duct D is provided with a drain-aperture over a re ceptacle G, in which surplus water is caught.

Openings at intervals longitudinally of each side of the air-ductD are preferably controlled by gates or valves H, and these openings communicate with compartments in which grain is germinated, their elevation being a suitable distance above perforated false bottoms constituting malt-floors I, located in said compartments. At intervals in a longitudinal direction the space below each false bottom or malt-floorI is open to a horizontal air-duct J, that has communication with a Vertical flue K, leading to an upper horizontal air-duct L, and gates or valves M are preferably employed to control the openings. It is preferable, as

herein shown, to have the openings in duct J alternate with those in duct D, aforesaid, these ducts being opposite one another on diflerent horizontal planes and extending in the same direction as the malting-floors Attemperated moist air from each duct D of the malt-house is diffused transversely of the adjacent parallel germinating-compartments and passes down through the perforated false bottoms I of said compartments into ducts J, from which it ascends fines K into the duct L, that is connected in practice with the casing of a suction-fan or other airexhaust apparatus.

By circulating the attemperated moist air transversely instead of longitudinally of the germinatingcompartments the best results are obtained, and by means of the gates or valves aforesaid the ventilation can be readily regulated to meet the requirements of growing malt throughout said compartments that alternate with the ducts in which the attem perated and filtered air is moistened.

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

1. A malt-house having an upper attemperating chamber, germinating compartments below the chamber, perforated false bottoms in the compartments, horizontal air-ducts in communication with said chamber and compartments abovethe false bottoms of the latter, other horizontal air-ducts in communication with the germinating-compartments below said false bottoms of same at sides opposite those to which the former air-ducts are adjacent, all of said ducts being lengthwise of said compartments, and vertical flues leading upward from the lower ducts, whereby descending attemperated moist air is diffused from side to side of the aforesaid compartments on its way through the material therein.

2. A malt-house having an upper attemperating chamber, germinating compartments below the chamber, perforated false bottoms in the compartments, horizontal air-ducts in Valve controlled communication with said chamber and compartments above the false bottoms of the latter and lengthwise of the same, other horizontal air-ducts in valve-controlled communication with the germinatingcompartments lengthwise of same below the false bottoms therein and at the sides thereof opposite those to which the former air-ducts have hereunto set my hand, at Milwaukee, in are adjacent, and vertical fiues leading up- 1 Ward from the lower ducts, whereby the dei soending attemperated moist air has diflusion from side to side of the aforesaid compart- Witnesses:
