IMPROVEMENT IN GRAIN-REGQSTERS.

To all whom it may concern: 'Be it known that I, STEPHEN RAMER, of Winona, in the county of Winona and State of Minnesota, have invented a new and valuable Improvement in Grain-Registers; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a pa'rtof this specification, and to the letters and figures ofreference marked thereon.

Figure l of the drawin g is a representation of a top view of my invention. Fig. 2 is a top view with cover removed.

My invention has relation to grain-registers; and it consists in the construction and novel arrangement of a graduated ratchet-disk havin g numbers, representing bushels, from one to one hundred; also, in the construction and novel arrangement of a notched slide having numbers from one to ten, representing hundreds of bushels also, in the construction and novel arrangement of a pivoted arm bearing a number to indicate half-bushels; and, lastly, in the construction and novel arrangementof devices for actuating the above-mentioned registerin g mechanism, substantially as and for the purpose hereinafter more fully described.

Referring to the drawing, A represents the box containing the registering devices; 13, a sliding lid to said box, having a glass panel, I), through which to see numbers U, a pivoted rotary disk, graduated around its rim and numbered from one up to one hundred, the numbers representing bushels of grain. The disk is provided with a flange, 0, having one hundred teeth, corresponding to the numbers on the face and beveled to the form of ratchetteeth. 1) designates a plate, placed over one side of the disk, and so slotted, as shown at d, that the figures indicating the quantity of grain transferred may be seen, and only such figures. D represents a spring-pawl, working in contact with the teeth of the graduated disk and arranged to turn said disk the distance of one tooth or one number, representing one bushel, at a time. The pawl D is secured to a transverse lever, D having its rear end pivoted to the bottom of the box A. The forward end of this lever is recessed on its under side to allow the ratchet E to turn. This ratchet has four teeth, and is pivoted to the bottom of the box A. A cam, in, consisting of an oblong block, having its sides parallel and its ends convex, is secured to the face of said ratchet at its center. G designates a spring-pawheu gaging with the teeth of the ratchet E, and secured to a lever, F which is pivoted to the shaft of the ratchet, and is so recessed as to move partlybehind or underneath said ratchet. To the lever F is pivoted an arm, G running thence lengthwise of the box, and connected to a transverse arm, G which projects through the side of the box, and is then bent up and back to constitute the arm G which the grainmeasure strikes. lVhenever a filled measure, all the parts being in the position shown, is moved in the direction shown by the arrow, it strikes and moves the arm G The arm G" is thus moved lengthwise, and by means of the lever l? and pawlGthe ratchet E is turned a quarter revolution. By this means the cam l is turned from a transverse to a longitudinal position with relation to the box A, causing the lever D to be moved toward the graduated disk, and the latter by means of the springpawl to be turned the distance of one tooth and of one number, which appears added to the number of bushels already registered through the slot in the plate 1). The proper measures to be used are half bushels. After the measure passes the arm G the latter is thrown back toits originalposition bya spring, 9, secured to its shank g, and at the same time the lever F and pawl G moved so as to be ready for action to turn the ratchet another quarter revolution. The lever D is then raised by the action of a spring, F. The next qua-1* ter revolution, effected by the transfer of an other half bushel measure of grain, causes the cam to assume a transverse position and to push over an L-shapcd lever, H, which has on one end the fraction one-half, and to bring this fraction to view through the slot in the plate D. Thus, if the number of bushels trans ferred be at any time, say, fifty, and the arm or lever H be then moved, the fraction on the end will show that anotherhalf-bushelhas been transferred, making fifty and one-half bushels. The disk (3 and arm H move alternately hence the registration is by half-bushels. When the cam assumes aposition lengthwise of the box A the lever H is pushed back by means of a spring, I. The graduated disk is prevented from turning backward by a springdog, K. Opposite the number 25 a notch is cut in the rim of the graduated disk. As soon as the number of bushels reaches one hundred a stud, e, on a transverse lever, L, enters said notch, the lever being raised by a spring, L. This lever holds at its end a stud, m, which engages with teeth m in the edge of a bar, m, which is arranged to move at one side of the graduated disk, and to expose,

through the slot in the plate D, the number of bushels in hundreds, said bars being numbered from one to ten. Whenever the stud e is permitted to enter the notch the lever L moves toward the disk and pushes the bar in the distance of one tooth, equivalent to one hundred bushels. The notch is so beveled that as the disk continues to turn the stud e recedes, causing the lever L to pass to the next tooth of the graduated bar. The graduated bar moves through slots in blocks N. Near the upper end, as shown in the drawing, said bar has double-beveled teeth N, which receive'a pin or stud, O. Springs I press the bar toward the stud O and the studs m. The teeth N retain said bar with suflieient security at any'position to which it is adjusted; but, by reason of the double-beveled form of said ments of the arm G substantially as specified.

3. The graduated toothed bar m, in combination with the graduated disk 0 having the rim notched, the l ver L, studs 0 m, and spring L, substantially as I and for the purpose spec-- 4. The graduated bar m having the teeth; m N, in combination with the slotted blocks N and springs P, substantially as and for the purpose specified.

In testimony that I claim the above 1 have hereunto subscribed my name in the presence" of two witnesses.
