FRANKLIN S. BITTER, OF CHEBOYGAN, MICHIGAN.

GRAlN PRO-PORTIONER AND MIXER.

SPECIFICATION forming part of Letters Patent No. 574,270, dated December 29, 1896.

Application filed July 23, 1896.

T 0 aZZ whom it may concern.-

Be it known that I, FRANKLIN S. BITTER, residing at Oheboygan, in the county of Cheboygan and State of Michigan, have invented a new and Improved Grain Proportioner and Mixer, of which the following is a specification.

My invention is in the nature of a machine for measuring and mixing two or more kinds of grain in any portions desired; and it has, primarily, for its object to provide a machine of this character of a very simple and inexpensive nature in which the several parts are compactly arranged and constructed to effectively serve for the intended purposes.

IVith other objects in view, which will hereinafter appear, the invention consists in the peculiar and novel combination and arrangement of parts, such as will be first described in detail, and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which Figures 1 and 2 are perspective views of my machine as seen from the opposite ends. Fig. 3 is a perspective view of the duplex n1easuring-cylinder. Fig. 4 is a longitudinal section of the same, taken practically on the line 4 4 of Fig. 5. Fig. 5 is a cross-section of the same, taken on the line 5 5 of Fig. 4; and Fig. 6 is a detail view of the registering mechanism hereinafter referred to.

In its practical construction my invention comprises a casinghaving a plurality of upper or feed compartments A A, an intermediate chamber A, in which revolves the measuringcylinder B, having a plurality of-independent measuring -,compartments B B and a lower or mixing chamber 0, which is common to all the measuring-compartments and which has an outlet 0, as clearly shown in Fig. 4.

By referring now more particularly to Figs. 1 and 5 it will be noticed the feed-compartment and the intermediate or cylinder-holding chamber B are not in the same vertical alinement, while the mixing-compartment O is directly under the said cylinder B.

The object in arranging the several parts in such a manner is that the compartments B B have each a series of radially-disposed independent pockets Z) 17 having their sides and ends arranged parallel in the direction of their depth, which are adapted to be moved in Serial No. 600,271. (No model.)

communication with the feed-compartments A A and be filled as they pass thereunder, and as such compartments b b are a width less than the width of said pockets (see Fig. 5) and as the cylinder B in practice is slowly rotated the solid part b of the cylinder forms ahopper-bottom inclined in the direction of rotation of the cylinder, and thereby provides for a positive automatic feed of the grain into the pockets without danger of clogging.

The pockets 1) b in length are preferably the length of the feedcompartments A A, but may be of less length, if desired.

To regulate the quantity the different pockets may receive from the compartments A A, such pockets have a series of slideways b b to receive the removable slides b 17 To provide for readily changing such slides when desired, the ends of the casing have openings I)", having hinged covers, as shown.

ing-compartment O, which consists of a shaft 6, extended at one end and provided with a cog-gear F, held in mesh with large cog-wheel G on the cylinder-shaft B, which at the opposite end is provided with a drive-pulley 19 as shown.

On the shaft 6 is mounted a series of flights H, each having a threaded shank h, which is screwed into threaded sockets in the shaft, such flights being arranged at alternate angles, as shown, so as to provide for a thorough mixing of the grain. The conveyer in practice, while serving to feed the material to the discharge-opening, does not keep the chamber C clean of grain, but moves out a little every revolution, leaving balance to be thoroughly mixed before being discharged.

At one end the machine has a vertical casing I, in which is mounted a series of dials J counting from units to ten thousand and connected in the ordinary manner, as clearly shown in Fig. 6.

Within the casing I is pivotally supported a lever-arm K, the lower end of which extends through a slot a in the casing B (see dotted lines, Fig. 4) in the path of a projecting pin L, secured on the adjacent end of the cylinder B, as shown, whereby at each revolution of such cylinder the lever will be swung and through the medium of the pawl it turn the units-wheel one point.

E indicates a conveyer held within the mix- From the foregoing description, taken in :onnection with the accompanying drawings, it is thought the complete operation and advantages of my invention will readily appear.

It will be seen that by adjusting the slides in the pockets of the members B B diiferent quantities of different grain can be fed into the machine, which will be thoroughly mixed before being discharged.

By weighing theproduct of one revolution of the cylinder and afterward multiplying the number of revolutions made by the product of one revolution it will give the amount in pounds of the grain mixed. \Vhile I have shown the feed portion and the cylinder B provided with two compartments, it is manifest the same may have three or more of such compartments.

Having thus described my invention, what 20 I claim, and desire to secure by Letters Patent, is

1. The combination with the casing having a cylindrical portion A a mixing-chamber F, at the bottom and a feed-hopper having a plurality of compartments, such hopper having its discharge-mouths arranged at one side of the vertical axis of the cylindrical portion A of: the cylinder B, having a plurality of setsof pockets, having their months of a Width less than the discharge-months of the hopper, said pockets having their side and end walls arranged parallel in the direction of their depth, slide members adjustably held in such pockets, a rotary mixer and conveyor I'I, held in the mixing'chamber and means for operating the cylinder and conveyer substantiall y as shown and for the purposes described.

2. The combination with the casing having feedways A and A, at the upper end, a collooting and mixing chamber at the lower end having a combined mixing and conveyer mechanism, such casing having an intermediate cylindrical chamber, such chamber having covered openings in the ends, of the cylinder B, having two or more members B B each having a series of radial pockets provided with a series of slide-receiving grooves, and the slide members Zr, for regulating the depth of the pockets, all being arranged substantially as shown and for the purposes described.
