UNITED STATES I PATENT OFFICE.
FREDERICK W. VVIESEBBOOK, OF NEW YORK, N. Y.
GRAIN-DRIER.
SPECIFICATION forming part of Letters Patent No. 333,908, dated January 5, 1886.
Application filed August 23, 1884. Serial No. 141,283. (No model.)
To all whom it may concern:
Be it known that I, FREDERICK W. WIEsE- BROOK, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Drying Apparatus; 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 is an improvement on my Patent No. 255,371, granted March 21, 1882, and relates toimprovements in that class of driers in which the materials-such as grain, &c. are deprived of theirv moisture by being subjected to hot air under pressure in cylinders arranged in an inclosing-casing one above the other; and the object is to produce an apparatus for drying moist material such as grains, &c.-more especially that produced in breweries, and in which it can be deprived of its moisture and dried in a very rapidand thorough manner, so that they can be shipped to long distances or preserved for a long time without the danger of fermenting or spoiling, and said grains can thus be used as food for cattle, 8:0.
The invention consists in placing a series of stationary cylinders in an inclosing casing or housing, and arranging within said cylinders revolving shafts provided with spirally-disposed blades or agitators, by which the material is conveyed successively in opposite directions through the cylinders and drops alternately from one cylinder to the next one below. Said material is exposed in its transit through the cylinders to hot air under pressure from a furnace until thoroughly deprived of its moisture and dried.
It also consists in the construction of certain details and arrangement of parts, as will be more fully described hereinafter, and more specifically pointed out in the claims, reference being had to the accompanying drawings and the letters of reference marked thereon.
Like letters indicate similar parts in the different figures of the drawings, in which Figure 1 represents a longitudinal vertical section of my improved apparatus. Fig. 2 is avertical cross-section of the same. Fig. 3 is a detail view of part of the same.
In the accompanying drawings, A repre sents any suitable air-heater, in which a series of pipes or tubes communicate with a blower, B, at their upper end, and at their lower part, which contains the most highly heated air, with a hollow wall, that leads the hot air to a series of cylinders, C. These cylinders have a flue or opening, at, extending along their entire length, to which the lateral hot-air lines 1 2 3 4 5 are connected, preferably, in the central part of the cylinders. so shaped as to form oblong slots, which enter the cylinders in a tangential direction, and thus cause the hot air emanating therefrom to pass around the inner surface or periphery of the cylinders. The cylinders, having suitable flanges, are secured at each end to the end walls of a surrounding housing or casing. Said end walls consist of cast-metal plates, while the side walls are formed of suitable masonry. Within said cylinders are placed the shafts a a a a a, preferably made square, which receive motion from any suitable gearing.
In the drawings bevel gearing is shown, driven by a vertical shaft and any motive power. The shafts are provided with a series of spiral conveyer blades or agitators, b, so as to convey the material admitted to the upper cylinder from one end to the other, and in such manner that said material passes successively in opposite directions through the cylinders, and dropping alternately at the opposite ends upon inclined plates (1, secured to the end walls. On each side of said plates d are arranged perforated plates 6, (shown in Fig. 3,) closed at their upper ends, so that the vapors or moist air arising from the material can pass upward to the outlet fines or stacks D through said perforations without obstruction, while the material falls from one cylinder to the other one below in succession. The spaces within the casing surrounding the cyl- The fines a are inders serve as the vapor or hot-air ducts or Instead of the blades or agitators on the revolving shafts, a regular conveyer maybe employed, if desired, and the spiral blade may be perforated.
The material to be dried is lifted or forced into the uppermost cylinderby means of a conveyer, E, arranged in a receiving-hopper or receptacle, F, and passes through a pipe, G, gradually tapering toward the upper part, and after being thoroughly dried through the successive cylinders it passes through the outlet opening f in the lowest cylinder into a suitable receptacle, H, from which it can be carried to an upper floor by means of an elevator, I, or otherwise.
The operation is as follows: The material to be'dried being placed into the hopper and the machinery started, the conveyer will lift or force the same into the uppermost cylinder. The blades or wings of the shaft will take up the same, agitate it, and convey italong. while the currents of hot air emanating from the slots and the fines 1 2 3 4 5, coming in contact with the material, will evaporate its moisture or a part thereof. When the material reaches the end of the first cylinder, it will drop on the inclined plates and into the next lower cylinder, and so in succession until it reaches the bottom one in a dry state. It then passes through the outlet-opening into a receptacle, from whence it is taken up by the elevator or otherwise. The moist air or vapor passes through the stacks D.
Having thus described my invention, what I claim, and desire to secure by Letters Patent,
1. In a drying apparatus, a series of stationary cylinders having oblong flues arranged tangentially and extending from end toend of said cylinders, and connected to an airheating apparatus, substantially as and for the purpose specified.
2. In a drying apparatus, a series of sta tionary cylinders having oblong flues arranged tangentially and extending from end to end of said cylinders, and connected to an air-heating apparatus, in combination with the inclined detachable plates placed at opposite ends of a series of said cylinders, and the perforated vertical plates 6, all arranged substantially as set forth.
3. The series of stationary cylinders, con taining revolving shafts provided with spirally-arranged agitators, and connected bytangential slots or lines a to hot-air fiues, an airheating apparatus, and a blower, all substantially as and for the purpose specified.
4.. In a drying apparatus, the combination of aseries of stationary cylinders having revolving shafts provided with agitators, with a housing, inclined plates d, and vertical perforated plates 6, and connected by lateralflues and tangentially-arranged slots in the cylin ders, with a heating apparatus and blower, as set forth.
In testimony. whereof I hereby affi'x my signature in presence of two witnesses.
FREDERICK W. WVIESEBROOK.
