SPECIFICATION forming part of Letters Patent No. 391,570, dated October 23,1888.

Application filed May 11, 1888.

To aZZ whom it may concern.-

Be it known that I, DANIEL XVILDE, a citizen of the United States, residing at 'Washington, in the county ofVVashington and State of Iowa, have invented a new and useful Im provernent in Grain-Measuring Machines, of which the following is a specification.

My invention relates to improvements in grain-measuring machines; and it consists in the peculiar construction and combination of devices, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure 1 is a side elevation of a grain-measuring machine embodying my improvements, showing the same attached to the elevator of a thrashing-machine. Fig. 2 is a similar view of the opposite side of the machine, the elevator being shown in section. Fig. 3 is a front elevation of my improved grain-nieasuring machine. Fig. 4 is a detail perspective view.

A represents the elevator of a thrashing-machine, which is provided with the usual endless ohain of buckets, B, and has the downwardly-inclined discharge-spout G at its upper end, into which the contents of the elevatingbuckets are discharged in succession. On the front side of the elevator, at a suitable distance from the upper end thereof, is arranged a crossbar, D, the ends of which project beyond the sides of the elevator, and have their upper edges beveled on opposite sides, as shown.

. E represents a shaft, which has a notch on its under side, at a suitable distance from its outer end, engaging the upper edge of one of the projecting ends of the crossbar D, said shaft being thereby supported on the said crossbar. On the outer or front projecting portion of the shaft is journaled a measuringhead, F, the construction of which is as follows:

G represents a pair of circular disks, which are connected at their centers by a hub, H, that is journaled on the shaft E. The said disks have their perimeters beveled or inclined inwardly toward each other, and are then provided with flanges I, which are arranged at asuitable distance apart.

K represents radial partitioirplates, of which there are a suitable number, the said partition-plates extending from the hub to the cir- Serial No. 273,570. (Xo model.)

cumference of the measuring-head and con necting the disks G, and serving to divide the measuring-head into a number of measuring compartments, L, oflike capacity.

M represents two pairs of diverging arms, which have their connected inner ends keyed to the shaft E on opposite sides of the measuring-head and in proximity thereto. The outer ends of the said arms project beyond that side of the measuring-head which is under the discharge-spout of the elevator, and are turned inward toward each other and provided with screw-threads, as shown.

N represents a curved plate, which bears against the flanges I on one side of the measuring-head, andhasits upper end bent outward at a suitable angle to form a support for a hopper, 0, that is secured thereto, the said hopper being arranged under the discharge-spout and over one of the compartments of the measuring-head. To the outer side of the curved plate N, near the upper and lower ends thereof, are secured transverse clips P, the ends of which are bent outward at right angles to form ears having openings to receive the threaded ends of the arms M. Clampingbolts R are screwed to the threaded portion of the arms and bear against opposite sides of the lugs or ears, and serve to secure the curved plate rigidly to the arms,as will be readily understood. An arm, S, projects at right angles from the curved plate N, and has a notch on its under side at its inner end, which engages the bcveled upper edge of one of the projecting ends of the crossbar D, the said arm thereby forming a pivoted support for the plate N, so that the latter is free to swing upward and downward with the shaft E, which carries the measuring-head. The latter is provided on its outer side, at its beveled orinclinod ieriphery, with a series of laterally or obliquely arranged cams, T, which correspond in number with the compartments of the measuring-head, there being one of the said cams for each compartment of the measuring-head, and the said cams being arranged at regular distances It will be observed that the offsets or shoulders at the rear ends of the said cams are slightly in ad Vance of the partitionplates of the measuringhead. On the opposite side of the measuringhead at the o inositel inclined perimeter a. thereof, and aslight uistancein rear ol. each partition-plate, is a cam, U, of suitable size and shape.

On one side of the elevator, atasuitabledistance from the upper end thereof, is secured an inclined arm, V, to the outer end of which isjournaled an anti-friction roller, W, thelatter being just above the upper side of the revoluble measu ring-head when the latter is in its elevated position.

X represents a curved arm, which is secured to the same side of the elevator box or trough at a suitable distance above the arm V, and has its outer end bent downward and arranged in the paths of the cams T, for the purpose to be hereinafter stated.

The free end of the shaft E passes through a vertical slot in a guide-plate, Y, that is secured to the rear side of the elevator box or trough and projects beyond one side of the same, and on the said free end of the said shaft is arranged a weight, Z, which is adapted to be moved inward and outward on the shaft, so as to counterbalance the measuring -head, and thereby normally keep the same in its elevated position. The said weight Z has a set-screw, A, which is adapted to impinge on the shaft E, and by means of which the weight may be secured at any desired adjustment on the shaft. Rigidly secured to the shaft E at a suitable point is a circular disk, B, which is provided in its outer side with a notch or shoulder, O.

D represents a ratchet -wheel, which is journaled on the shaft E, bears against one side of the disk B, and has the peripheral ratchet-teeth numbered from 0 to 9 and representing units of measurement-say bushels. On the opposite side of the disk B is arranged a ratchet-wheel, E, which is also journaled on the shaft E, which is likewise provided with peripheral ratchet-teeth numbered from 0 to 9 consecutively and representing tens. The diameter of the ratchet-wheel D and E and of the disk B is equal.

F represents a coiled extensile spring,whioh is arranged on the shaft E, has its outer end bearingagainst a cross-pin or stop on the shaft, and'has'its inner end bearing against the center of the wheel E, the function of the said spring being to keep the wheel E normally in contact with the disk B.

G represents a spring-pawl, which is attached to the inner side of the wheel D and has the tappet-arm at its free end,which bears against the periphery of the disk B and pro- 5 5 jects across the periphery of the wheel E.

H represents a spring-arm or detent,which is secured to one side of the elevating-trough or box and has its free end engaging the ratchet Wheel D.

The operation of my invention is as follows: The machine is in its initial position, when the revoluble measuring-head is elevated and the wheels D and E are so turned that the figures 0 thereon are opposite each other. As the material in the elevating buckets reaches the upper end of the elevator,it is discharged through the spout into the hopper so as to sustain the weight of the revoluble head and of the contents of one of the measuring-compartment until said contents reach a certain unit of measure-say one bushel. As soon as this amount ofgrain is discharged into the revoluble head the latter is caused to descend slightly and to incline the shaft E so as to disengage the cam U, previously in contact with the stop-roller W, from the latter, and thereby enable the revoluble head to be partly rotated by the weight of the material in one of its compartments until the said compart' ment has moved entirely from under the plate N, thereby causing the lower side of the said compartment to be opened and the contents thereof to be discharged into a suitable receptacle or receiving sack or vessel. (Not shown.) As the measuring-head descends, the shaft E, by being inclined, raises the ratchet-wheel D, so as to cause the same to move from under the free end of the spring arm or detent H, thereby causing the latter to slip over the said ratchet-wheel and take a fresh hold on atooth below the one with which it previously engaged, as will be readily understood. As the revoluble head becomes lowered, as before stated,by the prepondering weight of grain, so as to cause one of the stops or cams U to disengage the roller \V, the said revolublehead rotates and discharges the accumulated grain therein, as before described, and while the revoluble head is thus partly rotated and its contents are being discharged the outer side of one of its cams T comes. in contact with the inner side of the outer end of arm X, so as to raise the revoluble head to its former position and assist the counterbalancingweight, and thus lower the rear end of the shaft E to its initial position, and by the descent of the said shaft cause the spring-arm H, by engaging a new tooth on the ratchet-wheel D, to turn the-said wheel D, so as to cause the figure 1 thereon to be ranged opposite the figure 0 on the wheel or disk E, and thereby indicate that one bushel of grain has been measured by the machine. At each subsequent similar operation of the meas uring-machine the wheel D is moved a corresponding distance until the same has made a complete revolution,when its pawl G will enter the recess in the disk B, and thereby become engaged with one of the teeth of the wheel or disk E, so as to move the latter forward one space on the eleventh operation of the machine, and thereby indicate that eleven bushels of grain have been measured, the figures on the wheels D and E being respectively 1 and 10, equal eleven, and so on, as far as the capacity of the machine will admit.

A grain-measuring machine thus constructed is especially adapted for measuring the grain discharged from a thrashing machine, but may be employed with equally good-results for other purposes.

Having thus described my invention, I claim-- 1. The combination of the counterbalance shaft or arm E, the revoluble head journaled thereon and having the side plates or disks and the radial partitionplates, and the curved plate N, covering one of the open sides of the revoluble head and connected to the counterbalance-shaft by suitable supports, for the purpose set forth, substantially as described.

2. The combination of the counterbalanced shaft, the revoluble measuring-head journaled thereon having the compartments and provided with the ears or stops U, and the roller or stop W, adapted to successively engage the said ears or stops U as the head partly rot-ates, substantially as described.

3. The combination of the counterbalanced shaft E, the revoluble measuringhead journaled thereon having the peripheral stops or ears U on one side and the oblique cams T on the opposite side, the stop V, to engage each of the stops U in succession as the revoluble head rises, and the arm X, adapted to be engaged successively by the cams T, so as to ele vate the revoluble head as the latter rotates, substantially as described.

4. The combination of the counterbalanced shaft, the revoluble head journaled thereon, the stops, substantially as set forth, to control the partial rotations of said head, the registering disks or Wheels on the counterbalancing-shaft revoluble thereon and movable vertically therewith, and the arm H, secured to a fixed support and engaging said registeringwheels, substantially as described.

5. The combination, in a grain-measuring machine,of the counterbalanced shaft, the revoluble head journaled thereon, stops, substantially as set forth, to control the partial rotation ofsaid revoluble head, the disk B", rigidly secured to the shaft and having the notch in one side, the numbered registering ratchet- Wheels D and E, journaled to the shaft and arranged in contact with the disk B, the pawl G, secured to wheel D and adapted to engage Wheel E, substantially as set forth, and the arm H, secured to a fixed support and engaging the wheel D, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

DANIEL lVILDE.
