Lettcrsletent No. 94,258, dated August 3l, 1869.

*C- r- IMPROVEMENT 1N SEEDING-MACHINE.

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

To -all whom t may concern Be it known that 1, W. AVAL' BRUNT, of Horicon, in the county of Dodge, and State of Wvisconsin, have invented a new and improved Seeding-Machine; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to Athe accompanying drawing, fin-ming part of this specification, and in which- Figure l is a longitudinal vertical section.

Figure 2 is a cross-section, through 'line a' :c of tig. 1.

Figure 3 is a detached view of the box M, enclosing the feed-cylinder.

Figures 4, 5, and 6, represent details of the box M.

The object of this invention is to improve the construction o' seeding-machines by the application of new devicesfor adjusting the teeth and their dra-gbars, and a novel construction of the boxes enclosing the feed-cylinders, as hereinafter described.

vIn the drawingsl A' A are the draught-wheels;

B, the seed-box, resting upon a fra-ine composed of two cross-pieces, b b, united at their ends by a metallic plate, C, and supporting between them the feed-cylinders, their shaft, and enclosing-boxes;

D D, the drag-bars;

E, a bar extending under the drag-bars, and' connected by a cord or chain to a lever, F, by which vto `raise or lower them all :it once; and b G G, the cultivator-teeth, attached to the drag- The teeth are constructed with a bifurcated shank, the rear part of which is articulated to the end of the drag-bar, the front partbeing curved and extending through a vertical slot in the drag-bar, as shown in iig. l.

Upon the upper end of the curved arm ofthe shank slips a. pla-te, H, provided with a fiange or lug, h, and

- a set-screw, It', by which it can be 'fixed at any point on the curved shank, so that when the machine is at work the nut will draw down against the upper edge of the drag-bar, and form a stop to holdv the .tooth in position; but, when the latter comes in contact with en immovable obstacle, the nut will slip and yield, and

- other.

let the tooth turn back ou its pivot, and passover'the obstacle.

The nut H may be struck up at a blow from an iron plate, and, together with-its screw, will not appreciebly increase the cost of thc machine.

The'bar E is intended' not only to raiseand lower` the drag-bars, but to keep them parallel with each To this end, a bent iron ro e, in the form of an inverted U, is aiiixed to the bar between each adjacent pair of drag-bars, as shown in fig. 2, the dragbars at the sides of thel machine being held in place by a bent rod, e', of the form seen in .,ig. 1.

The saine result may obviously be reached by omitting altogether the wooden bar E, and employing in its place an iron rodr properly bent up between the drag-bars and at the sides of the machine.

The boxes M M, enclosing the feed-cylinders, are

constructed in two pieces, m m', fitting together: at their'edges, and enclosing'between them the disk s,

which forms the end ofthe seed pockets, the whole being supported bythe two frame-pieces b b, by means of flanges, n n, cast as part of` the boxes, and resting upon the upper edge ofthe frame-pieces.

Each of the parts fm m is east iu one piece, through which extends the cylindershaft, and in which works the cylinder'. v

An opening is provided in the under side of the box for the escape of the seed.

The form and construction of these boxes are well 4 shown in gs. 3, 4, 5, and 6.

Having'thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

1-. The plate H, with lug h and set-screw h', when usedv in combination with drag-bar and tooth, as described.

The iglxes M M, when constructed of'the two parts m mf, enclosing between them the disk, as described, each of said parts m m being cast in a single piece, substantially as set forth. v
