IMPROVEMENT IN COMBINED BROADCAST-SEEDERS AND CULTIVATORS.

Specification forming part of Letters Patent IWL-110,447, dated December 27, 1870; antedated December 10, 1870.

To whom it may concern:

Be it known that I, JOSEPH E. FARGO, ot' Lake Mills, in the county of Jefferson and State of Wisconsin, have invented a new and useful Improvement in Combined Broadcast- Seeder and Cultivat-or; and I do declare that the following is a true and accurate description thereof, reference bein g had to the accompanying drawing, and to the letters of reference marked thereon, and being a part of this specification, in which- Figure 1 is an elevation of my improved machine. Fig. 2 is a plan of the same with the hopper removed. Fig. 3 is a vertical section of the feed-box, and Fig. et is a horizontal section of the same. j

Like letters indicate like parts in each ligure.

The nature of this invention relates to an improved construction of combined broadcast seed-sewers and cultivators; a-nd consists in the peculiar arrangement of recessed cylinders rotating in feed-boxes snrmounting the axle, for automatically delivering a regulated amount of seed to the spout-s, which have distributing-plates at their lower ends, whence it falls to the ground, and is covered by the cultivator-teeth attached to bars pivoted to a shaft in rear of the axle 5 the feed mechanism is operated by gearing from the tractionwheels; in the peculiar method of hanging the drag-bars, and the arrangement of the mechanism for raising and lowering the same also, the peculiar construction of the washers between the drag-bars.

In the drawing, A represents tractionwheels, and B a proper axle, mounted in and between them. One of the wheels has secured to its hub a spur-gear, a., which meshes with and rotates the pinion b, which has a halfclutch, b', on its outer face, and rotates loosely on the sleeve c, which forms an extension or prolongation of the feed-shaft O, with which it engages and transmits its motion by a pin through the shaft, projecting into slots in the sleeve. 0n the outer end of the sleeve a pin is thrown in or out of gear with the half-clutch b by the lateral movement of the sleeve, which is effected by a shifter, D, Fig. 2. The clutch b is so constructed thatfu-'hen'thrown in gear with the pin on the end of the sleeve, the latter, together with the shaft C, will not be rotated in the retrograde movement of the machine, a spring being coiled around the sleeve,

between its journal and shifter-collar, which allows it sufficient end-play for the purpose.

The shaft O and its sleeve rotate in bearings into the feed-boxes H, but one of which is shown.

I is acylinder, recessed with several grooves or corrugations, extending from one end to about midway of its length. This cylinder is secured to the feed-shaft C, and rotates within the feed-box H, its plain end serving as a journal.

The'grain or seed dropping into the feedbox from the hopper in the rotation of the cylinder, the grooves ll with seed, which they carry down until they reach an opening in the bottom of the feed-box, when the seed passes down and out of the spout J, when it falls on a distributing-plate, j, which is formed by turning back horizontally the elongated lip of the spout. Froln the plate j the seed falls broadcast on the ground.

In order that the seed may not run out at the side of the feed-box through the recesses in the cylinder, a washer fitting into said recesses is slipped over the cylinder and rotates with it, bein gheld against the face of the feedbox by clamps or other proper means.

In the back part of the feed-box is hung a vibrating guard, K, which is pressed forward toward the cylinder by means of a rubber or other spring, lc. The. face of the guard conforming to the outline of the cylinder forms the back of the feed-box. The purpose I have in the use of the vibrating guard is, that in case the seed or grain should be caught -in the rotation of the cylinder by the sharp corner of one of its recesses, it willnotbe crushed against the throat of the back-ot' the feed-box, were it stationary; but the spring 7c will allow the guard to recede a little and permit the seed to pass down.

'lo increase or diminish the discharge of seed, the shaft C is moved laterally by the shifter F, so as to bring more or less of the recessed portion ofthe cylinder within the feed-box.

L are drag-bars, journaled on a bar secured to the frame-standard in the rear of the axle, cach bar having a cultivator-tooth, M, attached underneath. The teeth are attached to the series of bars in a zigzag row.

The bars are separated from each other by hemispherical Washers Z, cast on a plate, which is screwed or otherwise secured to the side of the bar. This form of washer gives a longer bearing to the bar and lessens the tendency of the tooth t0 twist in its furrow.

N is a rock-shaft, pivoted or journaled eeeentrically in the anterior part of the i`ra1nestandard, and has secured to it a series of chains, O, one of which is secured to each of the drag-bars below.

P is a lever, secured to the rock-sh aft within reach of the driver, who sits on the hopper, and by which he rotates said shaft to raise or lower the shovels or cultivator-teeth.

Q is a notched quadrant, secured to the lever and rockshaft, which is held in any desired position by the dog It, pivoted to the axle, which has a stud projecting from one side, which engages with one of the notches in the quadrant.

To release the dog from the quadrant, a bellcrank lever, p, is pivoted to the gripe of the lever P, and by means of a wire, p', connecting it with a tripper, q, under the dog, the latter is raised out of the notch.

As the operation of this machine is so clearly shown in the drawing and by the foregoing description, a further explanation is deemed unnecessary.

What I claim as my invention, and desire to secure by Letters Patent, is

l. The feed-shaft C and sleeve c, shifter D, clutch b', pinion b, and gear a, arranged and operating as and for the purpose set forth.

2. The partially tinted or recessed cylinders I, secured t0 the shaft C and rotating in the feed-box H, vibrating guard K, spring lr, spout J, plate j, and shifter F, substantially as dcscribed, and operating for the purposes herein set forth.

3. The rock-shaft N, eccentrically journalcd in the frame-standards E, and operated by means of the lever P, notched quadrant Q, dog It, bell-crank lever 19, wire p, and tripper q, for raising the dragbars L by means ofthe chains O, substantially as described.

4. The hemispherical washers l, in connection with the drag-bars L, when constructed and arranged as described and shown, and as and for the purpose set forth.
