HENRY N 0TH AND JOHN NOTH, OF DAVENPORT, IO\VA.
SPECIFICATION forming part of Letters Patent No. 380,588, dated April 3, 1888.
Application filed December 81, 1887. Serial No. 259,507. (No model.)
To all whom it may concern:
Be it known that we,HENRY N OTE and JOHN NOTH, citizens of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented a new and useful Malt- Stirring Machine, of which the following is a specification.
Our invention relates to improvements in nialting-machines in which a malting-tub is used, and the barley, during its process of being made into malt and at such times as desired, is stirred or turned over by means of wide screw-threads upon hollow rotating cones, while moistened air is passed through said barley. \Ve attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a top view of our machine, omitting the air-conducting box or tube. Fig. 2 is a vertical longitudinal section of our machine, as shown at lines a: m and y y in Fig. 1, together with the air-conducting tube or box.
Similar letters refer to similar parts throughout the several views.
A is the malt-tub with false bottom, preferably in separate detachable sections, as at B B B B B B B and B, preferably of boiler-iron,
the outer edges resting upon projection or ring a, on the inner surface of the tub about ten or twelve inches above its bottom.
0 is the vertical main shaft, resting in hearing or well a in the center of the bottom of the tub. Around shaft 0 is a sleeve, 0, the lower edge of which is fitted to the bottom of the tub, so as to be water-tight within. At a similar distance from the bottom of the tub, on sleeve 0", is a projection or ring, I), the inner edges of false bottom B resting thereon, and midway are standards d, resting on the bottom of the tub, for additional support to false bottom B. False bottom B is perforated with holes about onesixteenth of an inch in diameter, as shown at B, to permit air to pass through. If desired, two or more trapdoors, b and 1 may be constructed in false bottom 13 and bottom of tub for removing the malt or for conducting it to a conveyor.
In the bottom of tub A is inserted a waste pipe and cook, a, for drawing water out of the tub.
In the side of tub A, between its bottom and the false bottom B, is inserted an air-conducting box or tube, D, through which is forced air from a fan or air-pump into the tub.
An ordinary water-pipe having asprinkler, (Z, is inserted in the air box or tube I), through which water may be passed to dampen or moisten the air as it passes, and beneath sprinkler d the box or tube D is lengthened into a well, d, and waste-pipe to carry off the surplus water. Near the top of the tub, and upon its inner surface, extends a projection or ring, a are cut notches or half screw-threads a On shaft 0 is abeveled gearing or cog-wheel, E, and beneath is a loose sleeve, F, supported by a collar upon said shaft.
Attached to sleeve F, and extending outwardly therefrom,is a laterally-swinging wing, G, preferably constructed of two parallel beams, 9 and g framed together one above the other by standards f f f f f, the outer end of which wing has a hearing or projection on ring (1 One or more shafts, H HHH, are vertically insert-ed in boxes through beams g and g, or through bearings attached thereto, so as to permit rotation, the upper portion of said shafts having beveled gearing or cogwheels h h h h attached.
At the outer end of wing G is a frame, 6 6, having suitable hearings to accommodate the horizontal shaft I and permit its rotation. The end of shaft I terminates in worm 2', which engages with or works in the notches or half screw-threads a of tub A, and upon said shaft I is also the beveled gearing or cog-wheel i Hollow cones J, with wide screw-threads projecting therefrom, are attached by bolts or other suitable means to the bottom of each of shafts H and extend downward nearly to false bottom B. These cones J and screw are perforated with holes about one-sixteenth of an inch in diameter, and with sufficient number to permit the air to pass through.
Extending upward from wing G are standards k it it It, terminating in hearings to accommodate horizontal shaft K and permit its rotation. At suitable distances 011 shaft K are beveled gearing or cog-wheels Z Z Z l, which engage with similar wheels, h h h h, of shafts H, forming gearing. At the inner end of said On the upper edge or top of tub A drive-shaft K is attached the beveled gearing or cog-wheelm, which engages with beveled gearing or cog-wheel E on main vertical shaft 0, forming gearing, and at the outer end of shaft K is attached another beveled gearing or 'cogwheel, n, which engages with said beveled cog-wheel t on shaft 1.
Power is suitably applied to the main shaft 0 to rotate the same, which in turn causes rotation of horizontal drive-shaft K through said gearing, and also rotation of shafts H and cones J through said gearing previously described, and rotation of said shaft I and its worm 11 through said gearing connected therewith, and the rotation of worm z in said notches or half screw-threads a moves the outer end of wing G and its attachments around the outer edge of the tub and causes said wing and its attachments to travel in a circle around said vertical shaft 0.
In the drawings, Fig. 2, but one cone J is shown; but it is intended that each shaft H shall have attached thereto a similar cone J, and such number of shafts and cones may be used and such cones of such size and form as deemed requisite.
It will be noticed that such material may be used in the construction of our machine, or of parts of it, as may appear suitable.
The false bottom B may be made as suggested by the drawings, or constructed of more pieces of suitable size and form riveted together or otherwise attached, and other material than boiler-iron may be used, if desired.
It will also be observed that the form and construction which we have shown may bevaried and modified in many respects without departing from the scope of our invention.
WVe believe it best to arrange the size of the hollow cones J and screw-threads and so locate them that in revolving the screw-threads will move in circles similar to dotted circular lines shown in Fig. 1.
In the practial operation of our machine the barley is placed in tub A on false bottom B, and then submerged in water, and so remains untilin condition forgerminating or sprouting. The water is then drawn off through the waste pipe and cock a. Thereafter,when the barley has dried sufficiently, air is forced through the air-conducting box or tube D by means of a fan or air-pump (the air being moistened by water from sprinkler d) into the space between the false bottom B and the real bottom of tub A, and through said perforations in the false bottom the air is passed through the barley. During the same time, or at such intervals as are proper, power is applied to the main shaft 0, and cones J are rotated and moved around shaft 0 in a circle, while the screw-threads stir up and turn over the barley, and the perforations in said cones and screw-threads permit and continue the circulation ofair through the barley while so operated upon. After the barley has arrived at the proper condition, termed malt, it is removed from the tub, either by shoveling orpassed through the door-openings b b to a conveyer and then placed in the kiln.
Having described our invention, what we claim, and desire to secure by Letters Patent, 15-- The malting-tub A, having half screwthreads cut on top ofits wall, false perforated bottom B, airconducting box or tube D, and main vertical drive-shaft O, in combination with a laterally-swinging wing, G, having one or more vertical shafts, H,with screw-threaded hollow perforated cones J attached, and also having a right-angled shaft, I, and worm 43 attached, all geared with a horizontal drive shaft, K, connected with said wing, the whole suspended from said vertical drive-shaft, so that said worm may engage in said half screwthreads on the wall of said tub, and said horizontal driveshaft geared with said vertical driveshaft, whereby said cones may be rotated and said wing with its attachments caused to traverse around the wall ofsaid tub by the rotation of said wormin said half screw-threads, substantially as described.
