XVILLIAM MCCONAOHIE, OF BELLEVILLE, DAKOTA TERRITORY.

AUTOMATIC GRAIN-MEASURING MACHINE.

SPECIFICATION forming part of Letters Patent No. 400,100, dated March 26, 1889.

Application filed May 7, 1888. Serial No. 273,010, (Model) T0 aZZ whom it may concern.-

Be it known that 1, WILLIAM MOOONAOHIE, of Belleville, in the county of Grand Forks and Territory of Dakota, have invented a new and Improved Automatic Grain-Measuring Machine, of which the following is a specification, reference being had to the annexed drawings, forming a part thereof, in which Figure 1 is a front elevation of my improved automatic grain-measuring machine. Fig. 2 is a plan view, Fig. 3 is an end elevation, and Fig. at is a transverse section, of the measuring-box.

Similar letters of reference indicate corresponding parts in all the views.

The object of my invention is to provide a simple and eifective attachment to thrashingmachines for automatically measuring grain as it is thrashed and delivering it to a chute which will convey it to a wagon, so that the wagon maybe loaded and the grain measured without the employment of laborers, thereby saving considerable expense in thrashing and insuring accuracy.

My invention consists in a comparted box each compartment having a hinged door, and in the combination, with the comparted box, of a hopper provided with a movable deflector for directing the grain into one or the other of the compartments of the box.

It also consists in the combination, with the hinged doors, of a lever connected with the doors and arranged to cause them to move in alternation.

It also consists in the combination, with the hinged doors, of hooks for holding the doors in a closed position while the compartments are being filled, and in a device for releasing the catches, all as hereinafter more fully described.

The box A, forming the body of the meascontinuation of the partition 0 below the box A, is pivotally suspended from the sides of the box by ears a, turning on pins b, projecting from the box.

To the bottom of the box A are hinged doors E E, having side pieces, 0, for preventing the grain from escaping from the sides of the doors. The doors are provided with arms (1, which extend beyond the edges of the doors E E, for receiving the catches e 6, formed on the right-angled levers f f, pivoted to the side of the boxA. The horizontal arms of the levers. f f project outwardly in opposite directions and are pressed upwardly by the double spring g. The upward movement of the levers f f is limited by the pins h h. The doors E E are connected by rods 2'2" with opposite ends of a lever, F, pivoted to the side of the box, so as to cause the doors to rise and fall in alternation.

To the side of the box A, above the catchlevers ff, is pivoted a lever, F, which is provided with an eye, j, connected by a rod, is, with the crank Z on the driving-shaft m The driving-shaft m is provided with a pulley, w, which receives motion through a belt from any convenient source of power.

To the upper edge of the lever F are pivoted two right-angled levers, 0 0, the vertical arms of which are adapted to engage the horizontal arms of the catch-levers ff, and the horizontal arms of the levers 0 0 carry rods '19 p, having attached to their lower ends feet q q.

At the top of the machine is arranged a hopper, G, in which is arranged a deflector, H, upon the shaft 1. The shaft I extends through the ends of the hopper and is provided with a crank-arm, J, which is connected by a rod, K, with the door E. The upper edge of the deflector H is adapted to swing to one side or the other of the hopper, and the lower edge is arranged to swing first over one compartment of the box A and then over the other, its movements being controlled in the manner presently to be described. The grain is allowed to flow continuously into the hopper G while the shaft m is revolved by power, causing the lever F to oscillate, and consequently swing the levers O and O and the feet q q, carried by the said levers, alternately in opposite directions. So long as the compartment into which the grain is flowing is not full, the feet q q are allowed to move freely, touching nothing, and the ends of the levers o 0, carrying the feet g g, are held in a depressed position by their own gravity,

thereby holding the opposite ends of the said. levers away from the sides of the box A and out of engagement with the catch-levers ff; but when the compartment being filled has received the prescribed amount of grain the foot in that compartment upon its next downward excursion strikes the surface of the grain and turns the right-angled lever 0 or 0, so as to swing its vertical arm inward toward the box A and into engagement with the top of the horizontal arm of the catch-lever f or f, and thus release the door which closes the bottom of the compartment being filled, when the grain is immediately discharged, its weight causing the door to fall, and in so doing to raise the door of the other compartment, bringing it into engagement with the catch-lever. hen the parts are in the position shown in the drawings,the compartment B is being filled with grain from the hopper G, the grain being deflected into the compartment I) by the deflector ll. \Vhen the door E falls in the manner described, it not only raises the door E, bringing it into engagement with the catch 6, but it tilts the deflector II, so as to directthe stream of grain from the hopper G to the compartment B. At this time the said compartment B begins to fill, while the grain is flowing out of the compartment 1-3. The grain flowing out of the compartment B is prevented from affecting the motion of the door E by the apron D, which hangs down between the edges of the doors. The lever I 0011- tinues to oscillate, as before, and when the grain in the compartment 13 reaches into the path of the foot 1 the lever 0 is brought into engagement with the catch-lever f, thus releasing the catch and reversing the operation just described. In this manner the 001111321117 ments B B are filled and discharged in alternation, each filling of the compartments representing a measured quantity of grain.

The machine will be arranged to receive the grain from any suitable conveyor and to discharge it into another conveyer or chute.

IIavin g thu s described my invention, I claim as new and desire to secure by Letters Iatent 1. In an automatic grain-measuring machine, the combination, with. a box divided into two compartments and alternately opening and closing doors for the bottom of the compartments, of catches pivoted to the side of the box for locking the doors closed, a locking-lever pivoted to the box, means for operating said lever, and catch-releasing mechanism carried by the said rocking lever and having arms or rods projectingdown into the compartments to be operated by the mass of grain, substantially as herein shown and described.

2. In a grain-measuring machine, the combination, with a box divided into two compartments and alternately opening and closing doors for said compartments, of catches for holding the said doors closed, a rocking lever, angle-levers pivoted to the rocking lever and adapted to engage the catches to release the same, and feet projectil'lg from the angle-levers into the compartments, substautially as described.

3. In an automatic grain-measuring machine, the combination, with the doors E E, arranged to move in alternation with each other, of the spring-actuated catch-levers ff, the lever F, the angled levers 00, carried by the lever 1 and provided with rods 1) p, the downwardly-proj ecting arms of the levers 0 0 bein arran ed to en a e the catch-levers b o I a a f, and the feet 1 q ,for engaging the mass of material being measured, substantially as specified.
