AUTOMATIC REGISTER FOR GRAINS, SEEDS, AND OTHER SUBSTANCES.

SPECIFICATION forming part of Letters Patent No. 293,129, dated February 5, 1884. Application filed November 3, 1883. (X model.)

To aZZ whom, it may concern.-

Be it known that I, JOHN \VHERRY, J r., of Putnam, in the county of Putnam and State of Illinois, have invented a new and useful Improvement in Automatic Registers for Grains, Seeds, and other Substances, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional front elevation of my improvement. Fig. 2 is a sectional side elevation of the same, taken through the broken line 00 cc, Fig. 1. Fig. 3 is a rear elevation of the lower part of the same, partly in section and part being broken away. Fig. 4: is afront elevation of a part of the same, showing the registering mechanism.

The object of this invention is to facilitate the measuring of grains, seeds, and other substances as they come from a thrashing-ma chine, a bin, or other receptacle, and also to promote accuracy in such measurements.

The invention consists in a grain-resister constructed with a two-compartment case provided with an adjustable guideplalte connected by levers and rods with hinged bottoms having elastic bars engaging with weighted scalebeams, whereby a given weight upon one bottom will shift the guide-plate and raise the other bottom into position. The scalebea-ms are provided with catches and spreaders, so

that the said elastic bars will engage with and release the said scale-beams automatically. The adjustable guide-plate is provided with a crank operating a push-pawl, which engages with a ratchet register-wheel provided with a wire to engage with a succeeding ratchet register-wheel, the said register-wheels being provided wit-h holding-pawls, so that the said register-wheels will be revolved through uniform spaces by the movements of the said guideplate, as will be hereinafter fully described.

A-represents the case of the register, the body of which is made rectangular in form. The upper part of the sides of the case A are inclined inward and then outward, forming a flaring or hopper-shaped mouth, the inward inclination of the sides being such that the throat thereby formed will be about half the diameter of the body of the said case. The body of the case A is divided into two equal compartments by a vertical partition, B, the upper end of which is at a little lower level than the lower ends of the inward inclination of the sides of the said cases.

To the front and rear sides of the case A, at the upperend of the partition B, is pivoted the lower edge of a plate, C, so that the said plate can be turned to either side, to serve as a chute to guide the substance into one or the other of the compartments of the case A: The

upper edge of the plate C swings in beneath the inwardly-pro ecting angle of the sides of the case A, as shown in Fig. 1, so that the grain or other substance, when entering the said case, cannot get between the upper edge of the plate C and the side of the case A and impede the movements of said plate. The plate C,when swung to either side, rests upon ledges or flanges D, attached to the inner surface of the case A, as shown in Fig. 1, to support the said plate against the pressure of the entering substance.

To each side of the plate C is attached an angular rod, E, to the angle or outer end of which is pivoted the upper end of arod, F, the lower end of which is hinged to the outer part of the bottom, floor, or platform G, attached to the rigid inner parts of the pair of bars H. The bars H are pivoted to a bar, I, or other support placed in a slot in the rear wall of the case A, and secured to a frame, J, surrounding the lower part of the said case. The side bars of the frame J are extended to the rearward, and are connected by a crossbar, J, to which and to the bar or plate J, attached to the lower side of the rear part of the frame J, are secured the lower ends of the bars K. The upper part of each bar K is bent inward, and is attached to the rear side of the case A, each bent bar K being in such a position that the rearwardly-proiecting ends of a pair of the bars H, will move along its opposite sides as the said bars are vibrated by the upward and downward movements of the hinged bottoms G. The projecting parts of the bars H are elastic, and between the bars of each pair is placed a scale-l cam, L, the inner end of which is pivoted to the pivot of the said bars, H. The outer end of each beam L,

Q teams or a tenonformed upon the said end, moves up and down in a slot in the lower part of the bar K.

To the upper side of each beam L, a little in the rear of the lower part of the bar K, is attached a catch, M, the ends of which project a little beyond the sides of the beam L, and are beveled upon their upper sides, so that the elastic bars H in their downward .movements will pass the said catch, but will carry the said beam L with them in their upward movements.

Upon the opposite sides of the lower part of each bar' K are formed projections N, beveled upon their upper and lower sides, so that the said projections will spread or separate the elastic bars H, to cause them, as they move upward, to release the catch M and allow the scale-beam L to drop back to its place, and to cause the said bars in their downward move ment to pass the said catch., As the bars H move down past the catch M, they spring in beneath its projecting ends, ready to raise the scale-beam L in their next upward movement.

0 isarod, the ends of which are bent upward at right angles, and are attached to the lower side of the forward part of the scalebeam L.

From the rod 0 is suspended a weight, 1 which is secured in place upon the said rod 0 by a set-screw, Q, which passes through the eye or block that connects the said weight with the said rod. Vith this construction the weight I? can be adjusted nearer to or farther from the pivoted end of the scale-beam L, according as alighteror heavier grain or substance is to be measured, so that the bottom G will trip as each half-bushel or other fixed quantity of the substance is received in one of its compartments. As the fixed quantity of the substance is received in a compartment of the machine, the bottom G of the said compartment drops and the substance is discharged. As the bottom G drops, the elastic bars move upward and release the scale-beam L, so that all the substance will escape, and the said bottom will remain in its downward position until raised by the downward movement of the bottom of the other compartment. The downward movement of the bottom of each compartment shifts the plate 0 so as to direct the substance into the other compartment, the operation of the machine being automatic. The elasticity of the bars H is regulated by a bolt, R, passing through them at a little distance from their pivots.

S is a plate, hinged at itsupper edge to the rear wall of the case A in such a position that its lower edge will rest upon the bottom G, to prevent any of the substance being measured from getting between the rear edge of the said bottom G and the rear wall of the case A and obstructing the movements of the said bottom.

To a projecting pivot of the guide-plate O is attached or upon it is formed a short crank, T, to which is pivoted a pawl, U. The pawl U engages the teeth of a ratchet-wheel, V,

pivoted to the case A, or to a support at tached to the said ease, the crank T being made of such a length as to cause the pawl U to revolve the ratchet-wheel Vthrough the space of one tooth.

To the ratchet-wheel V is attached a wire keeper or pin, XV, which, at each revolution of the said wheel V, engages with a tooth of a second ratchet-wheel, X, and turns the said wheel X through the space of one tooth. In the same manner a third and fourth ratchetwheel can be used, as may be required.

To the wall of the case A are pivoted pawls Y Z, to engage with the teeth of the ratchetwheels V X and hold the said ratchet-wheels frombeing turned back by the friction of the pawl U and wire XV. The pawls U Y Z are kept in place by keepers a, attached to the case A. The ratchet-wheels V X are designed to be provided with index-fingers and dials, to show the amount of the substance measured.

\Vith the arrangement herein shown the pawl U will be drawn back by the descent of one of the bottoms G and pushed forward to turn the ratchet-wheel V by the descent of the other bottom, so that when the weights 1? are adjusted to allow the bottoms G to trip as each half-bushel of the substance is received the registration will be made in bushels.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A grain register constructed substantiall y as herein shown and described, and consisting of a two-compartment case provided with an adjustable guide-plate, and hinged bottoms having elastic bars engaging with scale-beams, as set forth.

2. I11 automatic grain-registers, the combination, with the flanges D D, arranged on the inner and opposite sides of the case A directly under its throat, of the vertical partit'ion B, swinging plate 0, pivoted to the up per end of said partition, rods E F, and pivoted platforms G, substantially as shown and described.

3. In a grain-register, the combination, with the case A and the hinged bottom G, of the pairs of elastic bars H, the weighted scalebeams L, having catches M, and the spreaders N, substantially as herein shown and described, whereby the said hinged bottoms will be released when a given weight of the substance has been received upon them, as set forth. 7

i. In a grain-register, the combination, with the scale-beams L and the elastic bars H, of the catches lllf and the spreaders N, substantially as herein shown and described, whereby the said elastic bars are made to engage with and release the scale-beams automatically, as set forth.
