IMPROVEMENT IN GRAIN-DRILLS.

The Schedule referred to in these Letters Patent and making part of .the same.

To all whom it may concern Be it known that I, JOHN L. RITER, of Brownsville, inthe county of Union, and in the State of Indiana, have invented certain new and useful Improvements iu Grain-Drills; and do hereby declare thatthe following is a full, clear, and exact description thereof, reference being had to which- Figure 1 represents a side view of my seeding-machine, and

Figure 2, a plan view of the same. 4 Similar lettersindicate like parts in each ligure.

My invention relates to certain improvements 'in seeding-machines, the peculiarities of which will here inafter be fully set forth.4

In the accompanying drawingsl A represents the frame, to the upper side of which is attached the hopper, or seed-box B, by means of upright supports b b. y The hopper is made with seed-cells a a' ain its bottom, and is provided with the shaft, or agitator-bar C,

upon which is attached the feed-wheels a' a a'.

The slide D is madefwith a slot in. each end, which works into pins, `secured to the bottom of the hopper This slide is securedto the outside of the hopper by a thumb-screw, c, so that, by operating upon the thumbscrew, you can regulate the quant ty` of seed to be sown.

`About the centre of the agitator O, issecured the mitre-wheel E, which works into the mitre-wheel F, attached to the upper end of the shaft G, the other end of the shaft G having a similar mitre-wheel, H, attached to it, which works into a corresponding mi tre-wheel I, secured to the axle of the driver-wheel J, which is pivoted to the front end ofthe frame A.

By this arrangement a constant rotary'motion is the accompanying drawings, and in given to the seed-wheels a' a.' a"when the seeder is in operation. Y Y

0 O are'arms, pivoted at one end obliquely-to the frame A, and the otherend provided with metal straps 'R R, which work into a strap secured to the frame A,

K K, and. are. made with a slot 'in their upper ends,

and secured to the under side'of the hopper, over the seed-cells a a a, by means of a plate, m, placed over the slot, and a screw p'assed through the plate into the hopper.

By this arrangement the arms of the machine may be expanded or contracted without wasting any grain, as the screws work`into the slots, and the plates m vm cover the seed-cells a a a.

N N are the handles, and

M M braces securing the hopper.

Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent, isf- 1. The plates m my, in combination with the seedcells c al a and arms 0 0, substantially in the manner and for the purpose set forth.

2. The "slide D, in combination with the thumb'- screw c, substantially and for the purpose. herein set set forth.

In testimony that I claim the foregoing, I have hereunto set my hand, this 8th day of September, 186,8. JOHN L. RITER.
