UNITE LOYD s. GODFREY, OF BINGER, OKLAHOMA,

AUTOMATIC GRAIN-WEIGHER.

l/Veighers, of which the following is a specification.

My invention relates to grain weighers of that type embodying a divided grain receiving chamber, and a weight controlled swinging base therefor, adapted to automatically dump the grain when a prescribed weight has been placed thereon, and the object of my invention is to provide a device of this character, embodying several simple and novel structural elements and to provide connections for operating a simple tally to register the bushels dumped through the weighing apparatus and the price thereof.

In the accompanying drawings, illustrating my invention, and forming a part of this specification, and wherein like numerals are used to designate like parts throughout the several figures, Figure 1 is an elevation of one side of the complete apparatus, partly broken away and in section. Fig. 2 is an elevation of the lower portion of the opposite side of the grain receiving chamber, with the scale frames broken away, and, illustrating the tally device, and Fig. 8 is a fragmentary elevation of the tally operating levers in engagement with a portion of one of the tally wheels.

In the practical embodiment of my invention, I provide a grain receiving chamber 1, secured centrally within a rectangular frame 2. The chamber 1 is provided with a hopper 3, disposed thereon and leading therein, and is divided centrally by a partition plate 4: extending upwardly from the base of said chamber to a rotatable shaft 5 extending transversely through the base of the hopper 3, which shaft has a deflecting plate 6 secured thereto within said hopper, to engage the inner surface thereof, whereby the rocking movement of shaft 5 causes movement of said plate from one side of said hopper to the other, to cause the introduction of the grain within the chamber 1 upon one side or the other of the partition plate 4 therein.

The base of the chamber 1, comprises a plate 7, mounted to rock upon a transverse shaft 8, journaled between brackets 9 secured to opposite sides of the chamber 1 and alined below the partition plate 4, said Specification of Letters Patent.

Application filed November 10, 1908.

Patented Nov. 36, 1909.

Serial No. 461,980.

I base plate 7 embodying portions upon each side of said shaft 8, at an angle to one another, whereby when one portion thereof is in the upper position against the base of chamber 1, to close one compartment thereof, the other portion of said base plate extends downwardly at an angle and allows the contents of the opposite chamber compartment to discharge. Each of the side portions of the base plate 7 are provided with latch pieces 10 extending outwardly from the sides thereof toward the ends of the frame 2..

The ends of the frame 2 supports the outer .ends of scale bars 11, extending between the said frames and the receiving chamber 1, upon each slde of the latter, and fulcrumed to swing in a vertical plane upon transverse bars extending between the sides of the frame 2, adjacent the inner ends of said scale bars. The scale bars 11 are each provided with an adjustable weight 13, slidably disposed thereon between their fulcrum 19. and the outer end thereof, and are also provided with depending brackets 14:, one upon each side of their said fulcrum.

Mounted to slide horizontally and longitudinally through the lower ends of the scale bar brackets 1 1, are latch bars 15, provided with collars 16 thereon between said brackets, and pressed longitudinally, inwardly, by means of coil springs 17, surrounding the same between their collars 16 and the outer one of the brackets 16, into position to engage the latches 10 of the base plate 7, when the adjacent portion of said base plate is in the upper position against the base of the chamber 1, whereby to lock the same against downward movement until sufiicient grain has been dumped thereupon to overcome the scale bar weight 13. The scale bar will then swing vertically upon its fulcrum 12 to allow the latches 10 and 15 to pass one another, said latch 15, being longitudinally movable to allow of the passage thereby, of latch 10 when the same is again moved upwardly to the closed position, by the dumping movement of the op posite portion of the base plate 7.

The ends of the shaft 8, beyond the journals 9 thereof, are provided with angular arms 18, at each side of the chamber 1, the arm 18 at one end thereof being connected, by a vertical operating bar 19, to an angular arm 20 secured upon one end of the deflecting plate operating shaft 5, whereby the swinging movement of the base plate 7 is e rnsse communicated to the deflecting plate (3 whereby to detlect the gain from the hop per 3, into the compartment of the chamber 1 havingits base closed by a portion ot the base plate 7. The arm 18 upon the opposite sid vat the chamber 1, is pivotally connected at its end to the end of an arm 21, secured to and extending from a stud sha'tt journaled between the wall of chamber 1 and a e: sing 23, secured upon said 'all in spaced relation. The stud shaft carries thereon one of the wheels, of the tally. the other wheel of which is mounted upon a similar stud shatt in horizontal alinenient there with said wheels being provided with toothed peripheral edges in close juxtaposition, and totaling in bushels.

Inasmuch as the compartments of the receiving chamber are capable of holding halt a bushel of grain, ach, they must both be dumped, and the portions of the base plate 7 each lowered before the tally should register one bushel. To provide for this, the arm 18, connected to the tally arm 21, has a swinging pawl 2?, spring pressed in one direction by a Hat spring 28, whereby upon one movement of the base plate T, the pawl 27, in engagement with a teeth of one of the wheels, advances the wheel one tooth, and

upon the other movement of said base plate said pawl is returned to engage the succeed ing tooth.

From the foregoing description, the operation of my improved weighing apparatus and the connection between the same and the tally whereby to operate the latter will be readily apparent.

Having fully described my invention, I claim:

in a device of the cha 'acter described, the combination with a receiving chamber, haviug a partition dividing the same into compartments, and a base theretor, having swinging movement upon a central shaft below said partition, of a tally to register movement of said base, and operating levers, connecting said tally and said base, extending from the shafts thereof, and pivotally united at their contiguous ends, one of said levers being provided with means engaging the periphery of the tal y, substantially as described.

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