FFllCEQ PATENT V JOHN F. HENDERSON, OF MANTO N, MICHIGAN.
GRAlN-SEPARATOR.
SPECIFICATION forming part of Letters Patent 317,782, dated May 12, 1885.
Application filed March 3, 1885. (No model.)
To aZZ whom, it may concern.-
Be it known that 1, JOHN F. HENDERSON,
a citizen of the United States, and a resident of Manton, in the county of WeXford and State of Michigan, have invented certain new and useful Improvements in Grain-Separators; and I do hereby declare that the following is a full, clear, and. exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a plan View of my improved 1 5 grain-separator, the screen-casing having been removed. Fig. 2 is a sectional side elevation of the same, taken on the line a" m in Fig. 1. Fig. 3 is a side elevation of the same, the screen-casing have been removed, and Fig. 4: is a sectional end elevation of the same, taken on the line y y in Fig. 3, parts having been broken away'for the purpose of better showing the construction.
The same letters refer to the same parts in all the figures.
This invention relates to machines for cleaning and grading or separating grain; and it has for its object to provide a device of this class which shall possesssuperior advantages in point of simplicity, durability, and general efficiency.
WVith these ends in view the invention consists in the improved construction and combination of parts, which will be hereinafter 5 fully described, and particularly pointed out in the claims.
In the drawings hereto annexed, A designates the frame of the machine, in the upper part of which is placed a cylindrical screen, B, the ends of which are provided with bands '0, arranged to revolve in annular bearings D, which are flanged, as shown, to receive the bands 0, and thus hold the screen B from longitudinal movement. The annular bearings D D are provided with laterally-extending gudgeons E E, of which those of the rear hearing are journaled in the tail end of the frame, thereby permitting the screen to rock upon the bearings or pivots thus formed,while the gudgeons E of the front bearing, D, are journaled in eyes formed in the lower ends of rods F, the upper ends of which are provided with lugs, having screw-holes to receive the screws G, which are swiveled to the top bars of the frame A, at the front end of the latter, and are provided with hand-wheels H, attached to their upper ends, by which they may be conveniently turned, so as to raise or lower the front bearing, D, and the end of the screen mounted therein, thus giving the screen B more or less inclination, as the work to be done may require.
To the outside of the screen B is attached an annular ratchet-wheel or band, I, the teeth of which engage with the upper end of a pawl, J, the lower end of which is connected by an eccentric strap or other suitable means with an eccentric disk, K, secured upon a longitudinal shaft, L, mounted in suitable bearings in the frame A, and the rear end of which is provided with a pinion, M, meshing with a bevelgear, N, attached to a transverse shaft, 0, which revolves on bearings in the frame A, and upon which is mounted a gear-wheel, P, meshing with a gear wheel, Q, attached to a short shaft, R. The latter revolves in bearings in the frame A, and is provided with a fast pulley, S, and a loose pulley, T, to receive a driving-belt from any convenient power. In lieu of this, however, a crank or crankwheel or other suitable means may be used for driving the machine by hand.
Attached to the shaft 0 is a fan, U, inclosed by a casing, V, the discharge-spout of which, W, opens below the upper end part of the screen 13, so as to discharge the air-blast into the'said upper end part of the screen. The screen B is formed of sections of wire-cloth of different fineness of mesh, the head-section being the finest, and each following section toward the tail endof the screen being coarser than the preceding section, so that the grain will be graded as it passes through the machine, the chaff and other light impurities being blown out at the tail end of the machine. The grain from each section is receivedin a compartment, X, in the lower part of the frame A, which compartments are made with inclined bottoms and with discharge-spouts Y, secured in openings in the casing of the machine. The grain, as it passes out through the said spouts, may be received in measures, or in receptacles of any suitable kind. The refuse, which is too heavy to be blown away and too large to pass through the meshes of the screen, will pass out at the tail end of the screen, and is received in the tail compartment X. The grain to be cleaned and separated is introduced into the screen B, at the head end of the latter, through a suitable feed spout or hopper, Z.
Having thus described my invention, I claim and desire to secure by Letters Patent of the United States 1. In a grain-separator, the combination of a cylindrical screen, annular bands at the ends of the same, annular bearings for the said bands provided with laterally-extending gudgeons, fixed bearings for the gudgeons of the rear or tail end bearing and vertically-adjustable bearings for the gudgeons of the front bearing, substantially as and for the purpose herein shown and specified.
2. In a grain-separator, the combination of a cylindrical screen, an annular pivoted or rocking bearing for the tail end of the same, an annular bearing for the front end having laterally-extending gudgeons,vertical rods F, having eyes or bearings for the said gudgeons, and provided with lugs at their upper ends having screw-threaded perforations, and swiveled hand-screws passing through the said lugs, substantially as and for the purpose herein set forth.
3. A grain-separator comprising the frame, a fan blower, a graded cylindrical rotary screen, an annular ratchet-wheel secured upon said screen, a pawl engaging said ratchetwheel, an eccentric wheel or disk arranged to operate the said pawl, and suitable operating mechanism, whereby the grain will be cleaned and graded as it passes through the said screen, substantially as and for the purpose set forth.
In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
JOHN F. HENDERSON. Witnesses:
O. H. GARNs, W. 1?. SMITH.
