IMPROVEMENT IN COIVIBINED SEED-SOWER, HARR-QW, ANU ROLLER.

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

To all whom 'it may concern:

panying drawings, making a part' of this application.

My invention consists in such an arrangement and construction of parts, that it may be altered to a seedsower and harrow, barrow and roller, or roller only.

'To enable those skilled in the artto makeand use my improved machine,'I will proceed to describe the construction. and operation of the same, referring lto the accompanying drawings by letters, andv in which- Figure 1 is a top view of' my improved machine;

Figure 2, a section of the same, atv the line xx, Figure 3, a longitudinal vertical section, at the line Figure 4, a side view, with the h-arrow and seedsower detached; and

Figures 5 and 6, detail views on increased scale, showing the boxes in which the roller rotates, iig. 6 being a section at line z z of fig. 5.

Similar letters of 'reference denote like parts in the different figures, A A are two side rails, and B B, two cross-bars, forming the frame for the roller C, which is provided with an axle, a, the ends of which rest and revolve in bearings near the rear 'ends of the side rails A A.

The rear one of the two cross-bars B B is provided with seed-channels, or chutes, through which the seed flow from the hopper D, said hopper being arranged on the cross-bar B, by means of staples, b, passing over` tangs, c, arranged on the ends of the hopper. The hopper is provided with a 'sliding bottom, provided with seed-holes, which coincide, in a given position, with holes inthe bottom proper and the chutes of the cross-bar B, so that,by means of the lever E, the iiow of seed may be increased, diminished, or entirely stopped. S is thel tongue, which is secured to the cross-bars B B, as shown. Y

The rear ends of the rails A A are provided with brackets, G, to which is secured a platform, F, on which is secured the seat H, which has a hinged lid, in orfder that it may be used as a tool-chest.

Suspended from the platform F, upon a suitableV iame, is the foot-board l, provided at one end with a pin, j, which serves as the fulcrum for the lever E.

rlhe roller G isshorter than the distance between the4 side rails A A, to an extent equal to the combined thickness ofthe two side rails J J of the barrow-frame, and a trie'more, which will enable the roller to rotate 'eely between the rails of the harrow-franie, the journal-boxes, shown at figs. 5 and 6, serving as collars between the ends of .the rollers and the barrow-frame, to keep the rollerin place.

The barrow-frame consists of two side rails, J J, joined by thejcros's-bar K, in the centre.

The' forward ends are provided with bearings, for the reception of the axle of the rotary harrow L, and the rear ends are morti'sed longitudinally, to receive the square ends of the boxes on the roller.

They are also mortised vertically, to receive the wedges M. V n

In' the centre of the cross-barK is arranged a hook, or staple, to which, by means of one or more links, is attached the lever E, whereby the harrow-frame may be raised or lowered, when necessary.

A frame, or bent rod, is secured to the forward ends ofthe rails J J, a little in rear of the axis ofthe harrow, to which is secured the shield or screen O, which is bent Yin the arc of `a circle over the barrow, and secured, at its. opposite side, to the cross-bar K, by means of bolts or rivets.

The journal-boxes, shown at figs. 5 and 6, are made of wood and metal.

Prepresents the lwooden block, shaped as seen, and Q, a metal band, formed to embrace the journal,or axle ofthe roller, and give strength to the box. The square end is cut away vertically, to receive the wedge M, which passes through the side rails J J of the harrow-frame, for the purpose hereinafter explained.

R R fare belts, bands, or chains, passing around the roller C and barrow L, in grooves madeto receive the same, and keep them from contact with the ground'.

The operation & c., ofthe machine, is as follows:

The roller being in its frame, and having theljournal-boxes, or collars swung on its axle, the harrowfiame is attached by passing the mortised rear ends ot' its' side rails over the` square ends of the boxes, or collars on the roller-axle, the bands are then passed around the roller and harrow,and the wedges M driven in, which tightens the bands, and holds the two frames together.

The teambeing putin motion, the barrow-teeth areforced into the ground, and the barrow and roller both rotated, one operating upon the other through the me'- dium o f the bands R R. The seed are dropped, in any given quantity (by a gauge-pin) immediatelyin front ofthe barrow, which turns them in and throws the clods immediately under the roller, which derives a dragging as well as rotary motion from the resistance er1- .countered by the harrow, and thus eiiectually mashes the clods and'rolls the earth down.

'In going to or from the eld, or when obstruct-ions are encountered, the harrowfrarne and harrow are elevated ,by the lever at the foot-board of the drivers seat.

When it is desirable to reduce the machine to a simple roller, the seed-hopper is removed, the bandsB R are taken olf, (the wedges M being rst removed) the tongue S raised slightly, end'pushed backward, when the narrow-freine will slide oi' they square ends ofthe journals, leaving them upon ,the axle of the roller, to serve as collars to keepv said roller in place.

Having described the construction and operation of Iny improved machine,

What I claim as new, and desire to secure by Let- 4 ters Patent, is-

1.- In combination with the roller-frame A A `and harrow-frame J J, constructed as shown and described, fthe peculiarly-shaped bearings P Q, the belts R R, and wedges M M, all operating substantially as and for the purpose set forth.

2. A'combined seed-sower, barrow, and roller. cn-

pztble of conversion by menus of the peculiarly-shaped bearings PQ, belts lt R, and'wedges M M, as and for the-purpose hereinbefore specified.

3. In combination with the harroiv-frameJ J, when connectedwith the miler-frame A A by means ofthe bearings, P Q, belts R R, wedges M M, the screen O,
