IMPROVEMENT IN BROADCAST-SOWERS.

Specification forming part of Letters Patent No. 124,096, dated February Q7, 1872.

Specification describing a certain Improvement in Broadcast Seed-Sower, invented by CHARLES L. STORY, of Calhoun, in the county l of McLean and State of Kentucky.

Figure 1 is a front view of my improved machine, parts being broken away to show the construction. Fig. 2 is a top view of the same, partly in section, through the line Fig. l; Fig. 3 is a detail sectional view taken through the line y y, Fig. l.

The invention consists in the peculiar construction of the distributing-wheel, as hereinafter fully described and pointed out in the claim.

A represents the frame or platform of the machine, to the rear edge of which is attached the upper edge of a board, B, which rests against the body of the operator, and to the lower edge of which are attached a frame or arms, C, which project beneath and parallel with the board A. To the end parts ofthe frame-work A B C are attached the ends of two straps, D E, one of which, D, is designed to be passed over the shoulder, and the other, E, is designed to be passed around the body of the operator to support and steady the machine while being carried and used. To the upper side of the board A, near one end, is attached a hopper, F, the bottom of which is made in the form of the section of an inverted cone, as shown in Fig. l. The opening in the bottom of the hopper F coincides with an opening through the board A, in which openings is placed a vertical shaft, G, the upper end cf which revolves in bearings in an arm or support attached to the board A. The lower end of the shaft Cr revolves in bearings formed in or attached to the lower frame or arms C. To the shaft Gr, just above the frame C, is attached the distributing-wheel H, which consists of two disks, h h2, between which are placed angular plates or strips h3 h4. The larger angular strips h3 are placed with their angles toward and at a little distance from the centers of the disks h1 h2, and with the adjacent arms of the contiguous strips parallel or nearly parallel with each other. In the centers of the spaces, between the arms of the strips or plates h3, are placed the smaller angular strips or plates h4, which are also arranged with their angles toward the centers of the disks h1 h2, and the outer ends of their arms equally distant from the ends of the arms of the plates or strips h3, the spaces between the ends ofthe said arms being such as required for the proper distribution of the seed to be sown. By this construction the seeds are divided and subdivided as they are projected fromthe wheel H by the centrifugal force engendered by the ra-pid revolution ot' the said wheel H. Upon the upper side of the wheel H, and concentric therewith, is secured a short tube, h5, which projects upward to the opening in the board A, to receive the seeds from the hopper F and conduct them to the distributing-wheel H. To the lower end of the shaft Gis attached a small pulley, I, around which passes a band,J ,which al so passes around a large pulley,K, attached to the lower end ot' the shaft L. The shaft L revolves in bearings in the arms or frames C and board A, and to its projecting upper end is attached a crank, M. By this construction a slow revolution of the crank M and pulley K will give a rapid revolution to the pulley I and distributingwheel H. N is a short tube, the lower end of which tits into the mouth ofthe hopper F, where it is secured in place by a bayonet-catch or other convenient,A fastening. To the upper end of the tube N is attached the month of a bag or sack, O, to contain the seed to be sown. The bag or sack O is designed to be carried over the shoulder of the operator, and the seed fed from it into the hopper F, as required. The passage of the seed from the hopper F to the distributing-wheel H may be regulated or entirely stopped by adjusting a slide, P, which enters the lower part of the hopper F and slides back and forth upon the upper surface of the board A, as shown in Figs. l and 3.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- In seed-sowers, a distributing-wheel, consist ing of two disks h1 h2, plates h3 11.4, and tube h5, constructed and applied together substantially as described.
