ROTATING GRAIN-METER.

SPECIFICATION forming part of Letters Patent No. 496,406, dated May 2, 1893.

7 Application filed July 5, 1892- Serial No. 439,078- (No model.)

To aZZ whom it may concern.-

Be it known that I, EDWARD GILFORD, a citizen of the United States of America, residing at Cowles, in the county of Webster and State of Nebraska, have invented certain new and usefullmprovemen ts in Automatic Scales, of which the following is a specification, reference being had therein to the accompanying drawings.

Myinvention relates to weighing scales, and has for its object to provide such an instrumentality with two or more scale pans or receptacles for receiving grain or other articles to be weighed, and for automatically discharging the contents of one pan while bringing an empty pan into position to be filled, and to arrange and combine the various mechanisms, to adapt them to the use intended.

In the accompanying drawings Figure 1, is a side elevation of my improved scales. Fig. 2, is a vertical section of the same. Fig. 3, is a perspective view looking at the instrument from the back.

Referring to the drawings A, A, indicate two side bars, united crosswise by connections B,B. To the side bars A, A, are secured uprights 0, C, which are connected near the base and at the top by cross bars D, D; the uprights 0, G, are braced by means of rods E, E. The connection B is provided with raised portions b, b, in which are secured the pins a,a', upon the points of which rests the plate F. This plate is connected with the scale beam G, upon which is the usual weight H, and counter poise h, the beam being confined in its movement by a guard h.

Adjacent to the uprights O, C, and pivotally connected thereto by means of links d, d, is a rectangular frame K, K, the under side of which is provided with pins 6, e, that rest on the plate F; by this arrangement it will be observed the frame K, K, will admit of a move ment approximately vertical to the uprights O, O, and limited to the movement of the beam G, in the guard h; in this frame is pivoted a revoluble drum M, containing two or more pans or receptacles N, the drawings show three but it is obvious that more may be provided.

Upon the ends of the drum I secure a series of rods f, which I preferably locate a little in advance of the divisions separating the several compartments or pans, and slightly eccentric to the pivot of the drum, I place these rods on each side, one in advance of each division and when the drum is in its normal elevated position, two of them, one on each side will make contact with the vertical and downwardly extending ends of the spring 9, g, which are secured to the cross bars D, connecting the upper ends of the uprights O, 0', thus holding one of the pans or receptacles in the drum M, in position to be supplied with the grain or other articles to be weighed.

The operation of the device is then as follows: The Weight H, having been adjusted on the beam G, to indicate the number of pounds or fractions thereof to be weighed, the article is then supplied to the pan or receptacle N, which is in'position to receive it through the chute or spout P, and when the required weight has been deposited in the pan or receptacle, the frame K, K, will be depressed and will impart its movement to the plate F, and the beam G, carrying the weight H the depression of the frame will release the rods f, from their engagement with the ends of the springs g, g, when the drum M, will be rotated by means of the weight of the article which has been deposited in the pan upon one side, the rotation of the drum bringing the pan or receptacle down and emptying its contents into the chute or spout P, by which it is delivered into such other receptacle as may be provided to receive it after weighing. The rotation of the drum brings the next receptacle or pan N, to position, while the 00- operating rods f, engage the ends of the springs g, g',in the manner already described. It will be observed that the free ends of the springs g, g, are curved around so as to lay in the path traveled by the rods f, this is to allow the rods to impinge upon said springs and break the force of their contact with the fixed ends thereof.

This device will be found very convenient where a great quantity of grain or any like article is to be weighed as the emptying and return of the pans is rendered automatic.

Having thus described my invention, what I claim as new, and desire to secure by Leting provided with a rectangular plate having ters Patent, is

In an automatic weighing machine, a revoluble cylinder or drum divided into recep- 5 taclesandprovided with suitable stops, springs to break the force of the contact when the cylinder is brought to rest, a frame carrying said cylinder and adapted to receive a reciprocating movement in one direction by the weight :0 of the substance deposited in the receptacles of the cylinder, anda counter movement from the weight on the scale beam, said beam becounter sunk holes upon its opposite sides, the holes on one side being adapted to fulcrum the beam, and those upon the other to support the movable frame and cylinder, substantially as described.

In testimony whereof I have affixed my signature in presence of two witnesses.

EDWARD GILFORD. Witnesses:

JOHN C. WALLER, G. A. HARRIS.
