AUTOMATIC GRAIN-WEIGHER.

Ei?E-CIFECATION forming part of Letters Patent No. 341,159,:1ated May 4, 1886.

A pplication filed June 2'7, 188:).

1'0 all whom it may concern;

Be it known that l, NELsON MoERIsoN, a citizen of the United States,resi ding at Hoosiclz Falls, in the county of Renssclaer and State of New York, have invented certain new and useful Improvements in Automatic Grain- \Veighers, of which the following is a specification.

This invention relates to automatic grainweighing apparatus; and it consists in combinations and arrangements of parts, as hereinafter set forth and claimed.

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

Figure 1 is a side elevation. Fig. 2 is an end elevation. Fig. 3 is an end elevation showing the end opposite of that shown in Fig. 2. et is a side elevation showing the side opposite of that in Fig. 1. Fig. 5 is an interior view in elevation of the registering device. Fig. (5 is a top v ew of the springcatch If and lug a detached from the disk A. Fig. 7 is an end view showing the flange-roller a in connection with the receiver A.

O is a platform, on which the receiver is supported.

A is the grain-receiver, formed of disks connected by radial plates or partitions A, which divide it into four separate compartments. These compartments can be increased or diminished in number.

, G and C", as shown in Figs. 1 and 2, are posts or standards located each side of the receiver A. These standards are secured to the platform O, and extend upward to the top of the receiver and support at their upper ends the hopper F.

The scale-beam (Z is U-shaped, having its arms spanning the receiver and pivoted to the standards at c, and at their extreme ends supporting and giving hearings to the axle c, on which the receiver turns. The post or upright a has its foot fastened to the platform and its upper end slotted at e to receive the scale-beam, and bounds the latter in its movements. The lugs u? are fastened concentrically to the sides of the receiver, one for each of the compartments.

If, secured to one of the standards G", is notched, and has its end inclined, as shown,

Serial No. 170,046. (NO model.)

to guide the lugs a into the notch, and in the rear of the notch it is bent up in the form of the letter U, so as to better receive the shock incident to a sudden stopping of the receiver.

The weight B is adjustable along the scalebeam, and may be secured in any desired adj ustment by the setscrew Z).

E is a spout or chute to conduct the grain after it is weighed or measured into bags (1, being secured to the end of the spout by hooks a".

u is a roller, which can have a flange or not. I have shown it as a fiangeroller for the rim of the receiver or disk to roll on. This re ceiver can be supported by a roller on each side for each disk to roll on, and in this case no flanges are required on the rollers which support the receiver.

D is a registering device, which is fastened to the scale-beam 1, and is actuated by a tappet-whecl, c, on the axle 0, as shown in Fig. 5. The tappet wheel should have as many arms or tappets as there are compartn'ients in the receiver. Each tappet as it passes moves the adjacent wheel one space or one-tenth of its way round. One revolution of this wheel moves the second wheel one space or One-tenth of a revolution, and one revolution of the second wheel turns the third wheel one space or one-tenth of a revolution. The first wheel, therefore, registers units, the second tens, and the third hundreds. The lugs and the spring catch 2r are so located that the receiver is stopped after each partial rotation with one of the compartments underneath the hopper F, but inclined toward the spout E or the delivery side, as shown in Fig. 1, so that when the upper compartment is loaded with grain to the desired extent and the receiver is allowed to turn it will turn so as to discharge this compartmentthrough the spout into the bag (7.

The scale-beam d has one of its arms that is provided with the weight B graduated like an Ordinary scale -.beam for measuring pounds, and serves to gradually lift the receiver during each partial rotation. The perimeter of one of the sides of the receiver is divided into cams, equal in number to the divisions orcompartments. These cams run on the roller (1.

The arrows in Figs. 1 and 4 show which way the receiver revolves when in operation.

The operation of my weighing and measur- ICO ing apparatus is as follows; The weight Bbeing first adjusted on the scale-beam so as to allow the receiver to fall when a certain number of pounds of the grain to be measuredsay enough to make one bushelis put in its upper or receiving compartments, the grain is then poured into the hopper, eitherby hand or otherwise, and conducted-by the hopper into the upper compartment of the receiver. When a bushel of grain has been received into thiscompartment, the scale-beam tips up, causing the receiver to fall, thereby withdrawing the lug from the catch b and allowing the receiver to turn one-quarter round, bringing a second compartment underneath the hopper and emptying the first through the chuteinto the bag (1' or into any other receptacle. As the receiver falls its cam-rim strikes and rests on the roller (1, by which, as it turns, the receiver is again lifted graduallyto its first position, sothat the second lug a is brought in line with the spring-catch b and is caught in its notch. By this spring-catch the receiver is not only automatically stopped at the proper position for the second compartment to receive the grain coming through the hopper, but is also brought to an easy stop without shock or blow by means of the peculiarshape of the U- shaped spring, as shown at f. As the receiver turns to deliver the bushel of grain the tappetwheel 0', fastened on its axle, also turns, bringing one of the tappet-arms against a tooth of the first or unit wheel of the registering device and causing it to turn so as to show one bushel delivered. When the second compartment is filled, the receiver again falls and turns, emptying the second bushel, bringing up the third compartment, and registering two bushels delivered, and so continuously each bushel tips the beam, turns the receiver, delivers the grain and registers the number.

1. The combination of the rotating receiver having cam-faces corresponding to its partition with the supports or rollers a, on which the cam-faces ride, substantially as described, and for the purpose set forth.

2. In combination, a registering mechanism secured to and supported on the scale-beam and a rotating receiver provided as to its axle with a tappet device and pivoted on the arms of the scale-beam, so that the rotation of the receiver through its tappet device shall directly actuate the unit-wheel of the registering mechanism, substantially as described.

3. In combination, in a grain-weigher, a U- shaped scale-beam having its side bars pivoted to standards on the main frame, an intermittingly-rotating receiver having its axle taking bearing in the ends of the side bars and having a tappet device on its axle, a registering mechanism supported on one of the side bars, and a weight adjustable along the graduated edge of the other side bar, substantially as described.

4. In combination, in a grain-weigher, an intermittingly-rotating receiver having camfaces supporting rollers on which the camfaces of the receiver ride, and an elastic spring pawl or stop for catching and holding the receiver between its periods of rotation, substantially as described.

5. In combination, in a grain-weigher, an intermittingly-rotating receiver mounted and taking bearings in the ends of the side bars of a U-shaped scale-beam, a U-shaped scalebeam having its side bars pivoted to vertical standards rising from the main frame on either side of the receiver and bearing on the side arms, a weight for weighing and mechanism for registering the amount of grain passing through the receiver, a hopper supported on the tops of the standards, and a chute provided with hooks, conducting the measured grain into bags, substantially as described.

- 6. In combination, in a grain-weigher, an intermittingly-rotating receiver provided with cams on the perimeter of its disks, a U-shaped scale-beam bearing the receiver at the ends of its arms, a weight adjustable on the graduated edge of one of the arms, and aroller 0r rollers underneath the receiver on which the receiver rides to return it to its normal position, sub- U -shaped scale-beam pivoted to standards from the main frame and graduated as to one of its arms, a weight adjustable on the graduated arm, a registering mechanism attached to one of the arms, an intermittingly-rotating receiver taking bearings as to its axle in the ends .of the arms, atappet device on the axle actuating the registering mechanism, a hopper on the tops of the standards tying them together, a cushioned spring pawl to catch the receiver in its rotation, and ach ute to conduct the measured grain from the receiver, substantially as described.
