UNITED STATES PATENT OFFICE.
E. DAVIS AND ALONZO PALMER, OF HUDSON, MICHIGAN.
GRAIN-SEPARATE OR.
Specification of Letters Patent No. 31,591, dated March 5, 1861.
To all whom it may concern:
Be it known that we, E. DAVIS and A. PALMER, of Hudson, in the county of Lenawee and State of Michigan, have invented certain new and useful Improvements in Grain- Separating Machines, and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawmas and to the letters of reference marked thereon.
The nature of our invention consists in the combination and arrangement in the manner hereinafter described, of those parts which are particularly set forth.
In the annexed drawings Figure 1 is a longitudinal vertical section. Fig. 2 is a plan view. Fig. 3 is a partial side view.
In the figures A represents an ordinary grain separating machine case constructed in any of the known and convenient ways. This case is provided with the usual fan case, constructed in the ordinary way with one exception, and that is a section of said fan case is movable or adjustable section, as shown at H. The object of making this section movable is in order better to control the draft, regulating it at the will of the operator.
The shoe in this machine is provlded with the usual screens, and 1s hung in a manner A not unknown but is operated in a peculiar manner. This shoe is hung at one end by means of straps h, it, while atthe other it is provided with a spring bar (Z, which lies across the machine and rests upon rollers 50, w. When the shoe is set in motion it is allowed a longitudinal motion by the spring d, and also a lateral motion by the spring playing upon the rollers 00, 00.
Motion is communicated to the shoe from the fan shaft. To one end of the fan shaft is secured eccentrically one end of a rod (4. The other end of said rod is attached to a bell crank 79, which connects with a rod for giving lateral motion to the shoe. The other end of the fan shaft is provided with a pulley, G, to which one end of a rod 6, is secured eccentrically. The other end of this rod 6, is attached to a bar F, which lies under the shoe and across the machine. The bar F, is connected to the shoe by means of a rod 2', which runs longitudinally of the machine. When the fan shaft is set in motion a longitudinal motion is communicated to the shoe by means of the rod 6, bar F, and rod 2'. When a lateral and a longitudinal motion is communicated as above described the shoe will also have a partially circular motion resulting from the combination of the other two.
I, represents a trap door at the head of the shoe and opening into the fan case. This door is kept down by means of a spring m, and is raised and adjusted by means of a strap n, which is secured to it.
J, K, and L represent three screens of the shoe. Under the screen L, is situated a boX M, with an opening 8 in its side. All the cheat, &c., passing through the screen J, pass down through an opening under screen L, as shown by arrow 2, into box M, and thence out at opening 8, to the side of the machine 0, shown as opening at the head of the shoe into which a draft from the fan may be made to pass. WVhen the section H, is raised so as to direct a draft toward the trap door said door may be raised by the strap n, and the draftwill pass under the screen J, in the direction of arrow 1. By closing the trap door and adjusting the sec tion H the draft may be directed in the usual way.
To do not wish to claim all modes of directing the pan draft nor the modes differing materially from this of operating the shoe in this particular way; but
Having thus fully described our invention what we claim as new and desire to secure by Letters Patent is- 1. The employment in connection with the shoe of the connecting rod a, the spring d, the rod 6 attached eccentrically to the fan shaft pulley G, the bar F, and the rod 2', when arranged as shown by means of which a lateral, a longitudinal and at the same time a partially circular motion is communicated to said shoe substantially as set forth.
2. The arrangement of the sliding section H, of the fan-case with the trap door 1, spring m, and strap n, for the purpose of directing and regulating the draft at the head of the shoe substantially.
