GRAIN-WEIGHING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 375,163, dated December 20, 1887.

application filed April 27, 1887. Serial No. 236,316. (No model.)

To all whom it may concern:

Be it known that I, GEORGE P. JAMESON, of Abingdon, in the county of Knox and State of Illinois, have invented a new and Improved new'and improved grain weighing and measuring machine which is simple and durable in construction and very effective and automatic in operation.

The invention consists in the construction and arrangement of various parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in they claims.

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 side elevation of my improve ment attached to a thrashing-machine. Fig. 2 is an enlarged side elevation of my improvement, and Fig. 3 is an end elevation of part of the same.

My improvement is specially adapted for thrashing-machines which convey the thrashed grain into a machine which, after automatically weighing and measuring the grain, delivers it to a wagon or other receptacle.

Myimprovemeut A is supported on an L- shaped arm, B, secured by the end of its vertical arm to the top of the thrashing-machine O in such a manner that my improvement hangs over the side of the thrashing-machine O and can be swung sidewise. On the outer end of the arm B is hung a spring weighingscale, D, of any suitable construction,and connected at its lower end with a U-shaped arm, E, in which 'is mounted to turn the shaft F, carrying the grain-weighing cylinder G,which consists of the two circular end plates, G ,con-

nected with each other by four radial partitions, G", extending at right angles to each other, so as to form four equal compartments in the grain-measuring cylinder G. The Weight of the latter and of the U shaped arm Eis supported by a lever, H, engaging with its front 7 end said U-shaped'arm E, being fulcrumed on a U-shaped brace, I, secured to the braces I O and 1 fastenedto the arm B.

On the inner end of the lever H is mounted adjustably the balance-weight H, which can be accurately set on said lever H to balance k the grain-measuring cylinder G and its U- shaped arm E.

On the outside of the sides G of the grainmeasuring cylinder- G are secured the four lugs G held near the rims of said sides G and midway between the outer ends of the partitions G. The lugs G arealternately engaged by a hook, J, formed on the outer end of the lever J, fulcrumed on the brace I, and connected at its inner end with one end of a spring, K, secured by its other end to the U- shaped brace I. The position of the lever J can be regulated by a screw, L, engaging the top edge of said lever J and screwing in a U- shaped keeper, L, pivoted to the brace 1 the lever J passing through said keeper.

The lugs G are also alternately engaged on their other side by a hook, N, formed on the outer end of the arm N, pivoted on the lever J between its fulcrum on the brace I and its book J. On the under edge of the arm N, near its fulcrum, is formed a transverse lug, N adapted to engage the lower edge of the lever. J, whereby said arm N is held in a horizontal position in line with said lever J.

The grain-weighing cylinder G is prevented from moving sidewise and endwise by thelinks O, pivotally connected with the shaft F and with the lower ends of the braces 1 Into the compartments formed by the partitions G in the weighing and measuring cylinder G opens the lower end of the chute 1?, held in an upwardly-inclined position and supported at its upper end by the link Q and the L-sh aped arm B, which is provided with a pin, B, to prevent the link Qfrom slipping. Into the chute P opens a flexible chute, 0, connected with the upper end of the grain-elevator G", into the lower end of which discharges the spout 0, extending from the graiubox of the thrashing machine 0..

The operation is as follows: The grain-weighing cylinder G stands in its normal position, as shown in Figs. 2 and 3, in which the partitions G extend at an angle of forty-five degrees to the horizontal plane. The chute P opens into the top compartment and the grain delivered from the thrashing-machine by the elevator G to the chute passes into the chute 5 P and fills the upper compartment. The grainmeasuring cylinder G is held in this position by the hooks J and N engaging the respect ive lugs G on the sides G, of the cylinder G until the weight of the grain in the compartro ment moves the parts of the spring-scale D so far apart that the grain-cylinder G is lowered until the hooks J and N disengage the respective lugs G The weight of the grain in the uppermost compartmeet then causes the I 5 cylinder G to rotate, whereby the grain in said compartment is emptied into the wagon or other receptacle standing below the grainweighing cylinder. As soon as the grain begins to empty out of the cylinder G then the parts of the spring-scale D move again to their former positions, whereby the grain-cylinder G is raised to its normal position, and, as the cylinder at the same time rotates, then the next following lug G is engaged by the hooks J and N of the lever J and the arm N, re spectively. The lugs G of the grain-weighing cylinder G are disengaged from the hooks J and N as soon as the weight of the grain has moved the cylinder downward sufficiently so that the upper edge of the lug G is below the lower ends of the hooks J and N, and as the height of the latter can be regulated by the screw L it is evident that the grain in the respective compartments can be discharged when any desired weight is obtained. When the graiu-weighing cylinder G turns in the direction of the arrow a, as before described, then the respective lug G in its upward movement strikes against the under side of the arm N, thus lifting the same until thelug G strikes against the hook J, after which the arm N drops downward again, so that its hook N engages .the other side of the lug G and the lug N of the arm N, striking against the under edge of the lever J, prevents the further downward motion of said arm N. As the arm B can be swung sidewise, it permits of moving the grain weighing or measuring machine over a second wagon in case the first one is filled without interrupting the passage of the grain from the elevator G into the chute P.

The arm B may be mounted on top of the thrashing-machine or on the side or front of the same, or on a separate stand.

The machine may also be used for weighing coal or other substances, and employed not only in thrashing-machines, but also in stores, warehouses, &c.

In regard to the use of both spring-scale and scalebeam, or balance-weight, as it is used here, theobject is to accurately measure the grain, and this can only be done by weight, as grain varies so much in weight, by measure. Some grain falls short in weight, while other grain overruns inweightbythemeasure. Now, to simply measure the grain the spring scale or scale-beam, either one, would be sufficient; but to measure the grain accurately itmust be weighed, and the simplest means of weighing it is by spring-scales. If spring scales alone are used, the weight of the measure comes on the scales and you have the weight of the measure on scales over and above the weight of the grain, whereas in using the scalebeam (or balance-weight) the weight of measure is taken from the scales, so the scales support and show only the weight of the grain. In using the scale-beam (or balance-weight) in connection with scales I may always (by moving the weight back or forward,as the case may be) have the scales evcnl y balanced. In this way the scales are in no strain except in weighing the grain and showing to the ounce how much grain is in measure. I find by actual test the apparatus operates much more accu- 3 rately and with much more satisfaction with both spring-scale and scale-beam.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1 In a grain weighing and measuring machine, the combination, with a spring weighing-scale, of a counterbalanced grain-cylinder connected with said scale, lugs formed on the sides of said cylinder, hooks engaging said lugs, and adjustable lever-arms carrying said hooks, so that when the uppermost compartment of the grain-cylinder is filled with a cer tain amount of grain then the lugs are disengaged from said hooks, substantially as shown and described.

2. In a grain weighing and measuring ma chine, the combination, with a spring-scale, of a counterbalanced grain-cylinder connected with said scale and provided with four compartments formed by partitions secured to the sides of said cylinder, substantially as shown and described.

4. In a grain weighing and measuring machine, the combination, with a spring-scale,of a counterbalanced grain-cylinder connected with said scale and provided with compartments formed by partitions secured to the sides of said cylinder, and means, as described, for holding said cylinder in a locked position until its uppermost compartment isfilled with a certain amount of grain, as set forth..
