JOHN IIALLAHAN, OF DUBUQUE, IOVA.

GRAlN-MEASURER.

SPECIFICATION forming part of Letters Patent No. 460,577, dated October6. 1891.

Application filed January 26, 1891. Serial No. 379,115. (No model.)

To all whom it may concern:

Be it known that 1, JOHN IIALLAHAN, a citizen of the United States, residing atDubuque, in the county of Dubuque and State of Iowa, have invented certain new and useful Improvements in Grain -Measurers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apperta'ins to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to a new and improved grain-meter, having for its object the production of simple and highlyefficient means by which the grain from a single discharge-spout of a thrashing-machine can be alternately fed to alternately-operating bins or, measures which are automatically lowered at a predetermined weight, a record or tally being kept of the quantity of grain so measured or weighed.

A further object of the invention is to provide simple and efficient means for securing bags or sacks beneath each bin or measure.

To these ends the invention comprises the detail construction, combination, and arrangement of parts, substantially as hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a view in perspective of my improved grainmeter. Fig. 2 is a similar view, looking to the front, with parts broken away. Fig. 3 is a view showing the bins or measures and their pivoted bottoms. Fig. at is a view of the movable supply-spout. Fig. 5 is a view of the tally. Figs. 6 and 7 are enlarged detail views thereof. Fig. 8 is a detail view showing a modified form of supply spout or trough.

Referring to the drawings, A designates a frame or sppport, and a a semicircular rod attached at its ends to the side of a thrasher T, and to which the said frame is secured at its lower end, so as to be adjustable from one side to the other.

a is a sustaining-rod secured at its inner end to thrasher T and at its other end to the lower end of frame A, and c is a second rod the outer end of rod a which supports the outer end of the frame.

I3 is an approximately oblong box or casing, which is suspended by arms I) from the upper end of frame A, said box or casing being open at its ends and provided with a central vertical partition In this box or casing are two bins or measures C O, which consist each of a pivoted or inolinable bottom 0 and two parallel boards connected at one side only, the partition 12 serving to close the open side of each bin as the latter is being filled. Thcbottom of each binor measureishinged at itsinner end to the vertical partition b and at about its center it is provided with a transverse rod 0 secured at its ends to the parallel side boards of each bin. Under this arrangement the bottom O is held closed when the bin is used for filling, but inclines outwardly at its free end on the descent of such bin, thus discharging the grain. To each bin is secured a connecting-rod D which rods at their upper ends are secured to opposite points of a disk D, which disk is centrally hung, so as to be free to revolve by a loop (Z, suspended from a weight-scale E, secured to the U-shaped bar Z). In this disk are formed two grooves or slots CZ (1 wherein is designed to fit the bent end of a stop-arm e, secured to frame A. The said grooves or slots are preferably made as shown in Fig. 8, so that the stop-arm 6 stops the movement of the disk exactly on its center.

F is an elevator-belt located or inclosed in frame A, and is provided with a series of buckets for conveying the grain. This belt is passed around pulleys f, and motion is imparted thereto in any preferred manner. A

is lowered.

each bin one end of a cord f which is passed through a hole or aperture in the partition b and is brought up over the end of said partition and connected to the spent on the same side as the bin, to which its other end is secured. In this manner the lowering of either bin will move the spout over the otherempty bin. In lieu of this spout I may employ a trough f", having an open bottom and flaring sides, said trough being secured to the upper end of frame A by loosely-attached rods f From what has been said it will be seen that as the grain is supplied to, say, the bin 0 the arm 6 is in engagement with the groove or slot d (See Fig. 2.) \Vhen said bin has received its full quota of grain, which is preferably about one half bushel, the scales will permit the bins to lower, and when the disk is released from arm 6 it will turn on its pivot, causing the bin 0 to lower and discharge its contents at its lower end. By the time the groove or slot (1 is coincident with arm 6 sufficient grain will have been emptied from bin 0' to permit the elevation of the disk and cause the engagement of the arm c with said latter groove or slot. Grain is now being supplied to the outer bin 0, the discharge-spout having been moved thereover by the lowering of bin 0. When bin C is full, the above operation is repeated.

In Figs. 2, 5, 6, and 7 I have shown means for registering or recording the operation of each bin, and in thismanner an accurate record or tally is kept of the number of bushels or half-bushels weighed or measured. This registering mechanism consists of a series of disks II, to each of which is secured a ratchet-wheel 71', having each (save the final or outer disk h) a finger or projection 7L2, which is designed to engage the next higher wheel at each complete revolution. The disks are inclosed by a metallic frame I, having a central longitudinal slot 1' for viewing the numbers on the disks and reading the register. In the front of box or casing B are formed parallel slots '2', through which project short studs 7; of one of the bins or measures, (say bin 0,) said studs being designed to effect the movement of the first disk 11 of the series and cause the same to turn one point at each lowering and raising of the bin or measure 0. The disk h will in turn cause the revolution of the next disk at one complete revolution, and so on throughout the series of disks, said disk its being preferably numbered from one (1) to twenty, (20.) In this manner the exact quantity of grain measured can be readily ascertain ed and an accurate record maintained. The stud or shaft of the disk 7L3 has loosely secured thereon the inner ends'of two bars or levers jj, with the outer ends of which the studs t" are designed to engage. To the stud or shaft are secured the inner ends of upper and lower spring-arms j which at their outer free ends bear on the upper and lower edges of said bars or levers jj. To these bars or levers are movablysecured studs or pins j j,

which engage the ratchet-wheel h, and are allowed to slide upon the outer edge of the teeth by coil-springs secured thereto and to the bars or levers. As the bin lowers the bar or lever j, through its stud or pin 7, moves ratchet-wheel h one point, which will move the disk It one point, so that one half bushel will be indicated on the outer face of said disk, the pointer 71" pointing between the numbers thereon. hen the bin moves upward, the bar or leverj is raised and its stud or pin j engages and moves ratchet-wheel h the extent of one tooth. This upward movement serves to record the corresponding downward movement of the other bin C.

To the lower end of box or casing B, beneath each bin, are four (more or less) hooks K, upon which the bags 7.; are hung to receive the grain. A rod extends across from hook to hook upon each side over the ends of the bags thus held, and the pivoted right-angled arms 79, projecting from and attached, one on each side of each bin, to the box or casing B, are designed to close said rods down over each set of hooks outside of said box or casing to hold the bag on said hooks by bearing on said rods.
