IMPROVEMENT IN GORN-PLANTER.

TO ALL WHOM IT' MAY CONCERN:

Be it known that we, WILLIAM N. Hannrsou and Jonn J. HARRISON, of Hornby, in the county of Steuben, and State of NewYork, have invented a certain new and useful Improvement in Gorn-Planters; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, makingpart 'of this specification, in which- A Figure 1 is a plan. I

Figure 2, a front elevation.

Figure 3, a side elevation.

Figure 4, a rear elevation.

Figure 5 is a section of. the hopper, showing the slide and peculiar arrangement of the seed-roller.

Figure 6 shows the sliding rod and spring. 7

Like letters of reference indicate corresponding parts in all the figures.

Our invention consists in the arrangement of the machine as a whole, as hereinafter described, whereby the seed-tubes are made independent in their action. The covering-rollers are made yielding and elastic, and the hills are planted nearer together or further apart, as may be desired.

In the drawings, A indicates the frame, and B B the driving-wheels. On the axle is a spur-wheel, C, which engages with a loose pinion, D, on the seed-roller E, and the roller is made to couple with the pinion by a sliding coupling, F, moved out and in by a sliding rod, 6, connected with lever c.

The sliding rod is pressed up by spring g, so that notches d engage with sharp-edged bearing a, to hold'the 7 rod either out or in. G is the drivers seat.

At suitable distances apart, hoppers H are situated, above the seed-roller, being hinged so as to turn over.

Under each hopper the roller is provided with two sets of seed-hole s,ff, the holes of one set being situated nearer together than those of the other set. A blank, a, is situated between the twosets, and a slide, 2', fitting either angular side of the hopper, is made to strike down upon said blank, and therefore direct the seed into either set of holes described, the slide being changeable, as indicated by black and red lines in fig. 5.

' This is a very simple and convenient means of changing the distances between the hills, which in ditl'erent soils and in difierent conditions is necessary. The simple changing of the position of the slide will accomplish the result.

The usual stationary conducting-tubes I I, and sliding tubes J J, are employed beneath the hoppers, the latter serving to open the drills.

The sliding tubes are attached loosely to a cross-bar, j, suspended by a link, it, from a lever, is, which is within reach of the operator, so that he can raise the tubes at pleasure The great advantage of this feature is, that the cross-bar, being loosely suspended in the centre, caninclinc in'either direction, thereby adapting the device to irregular or inclined ground, either end rising or falling freely. This cross-bar is also of the simplest form, and serves as an attachment to the tubes, which cannot easily become disarranged.

This arrangement also facilitates the turning of the machine, for the tubes can be raised by a single move ment of the lever. I

A stay-rod, M, braces the tubes against a back strain. p

In the rear of the tubes are situated covering-rollers K K, connected with swing-arms m m, jointed at an to still? hangers O O. Atthe rear end, curved springs L L ,connect the arms with the underside of theframe, above that, making a connection throughout.

7 The advantageof this arrangement is that the springs hold the rollers down to'their work with the required pressure, and yet they yield in passing obstructions or irregularities, or in going over inclined ground. When the rollers are left to operate from their own weight, they fail to cover perfectly es ecially in passing over holes or depressions in the soil. The springs will always force them to their work, and produce the required hardness in the covering. In this connection the jointed-arms. are-also of importance in allowing the free movement. These rollers, by resting nearly imder the axie, snow :1. free movement in turning. y Inclined scrapers p10 are situated in the rear of the rollers, for removing the dirt. What we claim as ou"r in ven tiorieand desire to secure by Letters Patent, is-- The slide-tubes J J, attached to cross-bar j, the covering-rollers KK, connected with hingedarms m m, and springs L L, and the double sets ofseed-holesff, with shifting slide z, the whole arranged as described, and

operating in the manner and for the purpose specified.

In witness whereof, we have hereunto signed our names in .the'pr esence of two subscribing witnesses;

WM. N. HARRISON, JOHN J. HARRISON. Witnesses:
