AUTOMATIC WIND-REGULATOR.

SPECIFICATI ON forming part of Letters Patent No. 356,967 dated February 1, 1887. Application filed June 2, 1886. Serial No. 203,942 (No model.)

To all whom it may concern:

Be it known that I, ORLANDO ELBERTEN SCOTT, a citizen of the United States, residing at; Elkwood, in the county of Cavalier and Territory of Dakota, have invented new and useful Improvements in Automatic Wind- Regulators, of which the following is a specification. 1

My invention relates to an automatic windregulator for thrashing and clover hulling machines; and it consists of the peculiar combinations and novel construction and arrangement of the various parts for service, substantially as hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a side elevation of so much of a thrashing or clover-hulling machine having my improved regulator applied thereto as is necessary for a proper understanding of my invention. Fig. 2 is a vertical longitudinal sectional view through the same. Fig. 3 is a detached perspective view of my improved regulator.

Referring to the drawings, in which like letters of reference denote corresponding parts in all the figures, A designates a portion of a thrashing-machine, having the air-inlet ports a, to supply air to the blast-fan B, that is arranged on the plane of the said openings or ports a. 7

O is'the shoe that receives the grain, chaff, &c., from the cylinders of the machine, and this shoe is arranged to vibrate back and forth by suitable mechanism, as is customary in this class of machines. For the purpose of carrying my invention into effect the shoe is so arranged or hung at one end that it will be affected or depressed by the contents or grain therein; and to this end it is pivoted in any suitable 1nanner, or suspended so that it will descend under the weight of the contents, and is elevated when the load thereon is diminished.

. D designates a rock-shaft that is arranged within the casing of the machine proper, A, and the-ends of this shaft are journaled in the machine, or in proper bearings provided therefor. Within the machine the rock-shaft is provided with rigid crank-arms E, that project rearwardly of the shoe, andto the free ends of these crank-arms are pivotally con- 'nected the upper ends of hangers or links F,

the lower free ends of which are pivoted to the free end of the shaking or vibrating shoe 0, to suspend one end of the latter. When the free end of the vibratingshoe, to which the hanger rods or links F are connected, is depressed,

the downward movement thereof is communicated through the hangers F and crank-arms E to the rock-shaft D, to oscillate the latter in its bearings, and this oscillatory movement of the rock-shaft is communicated to the pivoted wind boards or shuttersG, to open or separate the latter to increase the supply of air to the fan B. The extremities of the rock-shaft are extended through the machine-casing A, and are provided with rods or levers H, that are rigidly secured thereon, and these levers are arranged exteriorly to the machine-casing and alongside of the same. The levers H are of sufficient length to extend to the wind-shutters G, and the free ends of the levers are provided with links or rods I, that are connected to the shutters G, to actuate the latter. The shutters are preferably of the usual form in common use, and they are arranged in pairs on opposite sides of the machine A. Each of the inlet-ports a of the machine is provided with one pair of these shutters, and the shutters of each pair are arranged on opposite sides of the openings or ports a, the upper end of each shutter being independently pivoted to the machine-casing, as at g.

The free end of each of the links I is connected to one of the shutters G near its pivoted end. When the rock-shaft is oscillated by the movements of the shoe, the levers H are likewise operated to actuate the movable shutters, and, as each leverH is operated simultaneously by the rock-shaft, the shutters will be likewise moved, thus simultaneously and instantaneously adjusting all of the shutters to the re- ICO ters, as they are connected therewith by the intermediate links. It will be seen that when the free end of the gravitating vibrating shoe is depressed by weight of the contents therein the rock-shaft will be oscillated to elevate the levers and thus distend the spring, and when the contents of the shoe are discharged the spring again draws the levers downward, and thereby elevates the gravitating shoe to its normal position. As the free ends of the levers are elevated against the tension of the spring, they draw upon the links I, and thus separate the wind-shutters, and when the levers are lowered the shutters close by gravity.

K designates a regulating-weight that is adjustable longitut'linally on one of the levers H, nearer to or farther from the rock-shaft by which it is carried. By moving the weight farther from the rock shaft the free ends of the levers H will be depressed to close the wind-shutters to a greater extent, and the free end of the shoe 0 will be elevated; and by adjusting the weight away from the free ends of the levers they will be raised to open the shutters partially and lower the free end of the vibrating shoe.

The blast-fan B is inclosed within a casing, L, that is made in two semi-cylindrical sections, L and L, the former of which is rigidly seeu red in place on themachine-easing by suitable bolts or other preferred means, and the section L is rigidly secured at its rear edge on a rock-shaft, M, that is journaled at its ends in the machine-casing, said case-section L be ing free at its opposite edge, and adapted to be elevated away from the adjacent section to permit the surplus air to escape through the opening thus provided, and the section L of the case is supported wholly and carried by the said rock-shaft M. The rock-shaft is provided with arearwardly-extending arm, at, that is arranged outside of the machine-casing A. A spring, N, of coiled form is connected at its ends to thelever H, near its free end, and to the arm m, at or near the point where it is secured on the rock-shaft; and the said arm at is further provided with a weight, 0, that is adjustable longitudinally thereon toward and from the rock-shaft M.

The operation of my invention is as follows: The adjustableweights K and Oare moved on the levers H and m, to adjust the shoe to the required elevation and the ease-section L to the desired position, so that the air is drawn between the case-sections and forced toward the rear of the machine by the fan, the adjustment of the lever H also opening or closing the wind-shutters to the required distance. After the machine has been set in motion and grain is fed thereto by the attendant, the cylinder and various other parts of the machine act upon the grain and deliver it to the shaking orvibratiug shoe which is depressed atits free end by the weight thereof, which pulls the hangers intermediate of the shoe and rockshaft downward and oscillates the rock-shaft. This motion is communicated to the levers H,

so as to open the wind-shutters and increase the supply of air to the fan,which forces it onto the shoe, and when the quantity of the contents of the shoe is diminished the shoe is elevated by the action of the retracting-spring upon the lever H, which in turn oscillates the rock-shaft and elevates the hangers or links F and the shoe to their normal positions. The downward movement of the free end of one of thelevers H relaxes the tension of the spring N, which allows the weight 0 on the arm on to descend and carry the free end of the said arm with it, which thereby actuates the rock-shaft M and elevates the free end of the case-section L to permit the surplus air to escape. The case-section L is also actuated independently of the movements of the levers by the increased force or pressure of the wind thereon, caused by the shutters being extended beyond their normal estimated position, so that the free end of the said case-section is elevated to provide an enlarged space between the meeting edges of the sections L and L to permit the surplus air to escape through the said enlarged space, the elevation of the free end of the section L oscillating the rock'shal't M and depressing the free end of the arm m, which draws upon the spring N and serves to depress the frce end of the levers II to partially close the wind-shutters. It will thus be seen that when the shoe contains a larger quantity of grain than the estimated weight to which the mechanism has been adjusted the free end thereof will gravitate or move downwardly to actuate the levers H to open the wind-shutters, and when the quantity on the shoe decreases through irregular feeding or other causes the free end of the shoe is elevated and the windshutters are correspondinglyclosed to shut off the air-supply partially, the whole operation being carried on automatically and without requiring the services of an attendant to adjust or regulate the wind-shutters after they have been once set.

My improvements are simple, strong, and durable in construction, and effective and re liable in operation. The regulating-weights can be readily adjusted to adapt the mechanism for use under varying conditions, and access to the weights is readily had, as they are arranged exteriorly of the machine-casing A. The mechanism is cheap and inexpensive, and can be applied to any class of thrashing-machines, either before or after they have left the factory.

I do not desire to confine myself to the exact details of construction and form and proportion of parts herein shown and described as an embodiment of my invention, as I am aware that many changes therein can be made without departing from the principle or sacrificing the advantages of my invention.

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