Letters Patent No. 94,674, dated Sqitenbef 7 1869.

IMPROVEMENT IN SEEDING-MACHINES.

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

do hereby declare that the following is a full, clear,

and exact description of the construction and operation of the samereference being had to the accompanying drawings, making apart of this specification, in which- Figure l is a plan, a portion of the tongue and one of the braces N having been broken away to show the construction of the joint that connects them.

Figure 2 is a longitudinal vertical section, a portion of one of the drag-bars having been broken away to reveal the construction and operation of the wedge that holds the teeth.

In this invention, the construction of the frame is greatly simplified, and better adapted for its purpose, and a novel method of holding the teeth is employed, whereby they letain their proper position when working in tillable soil, but yield to immovable obstacles.

In the drawings- AAare two parallel cross-beams ofthe frame, united at their ends by metallic plates or castings B B, which furnish a bearing, b, for the axles G O, the latter being supported at their inner end by short stout bars E E, fastened to the under edge ofthe beams.

D D are the drag-bars, supported at their forward end upon a rod, d, which extends from a lug at the lower rear corner of one plate B to a similar lug on the other plate.

" These drag-bars are connectedv by a bar, F, lying i across their back, said bar being attached loosely to eaclrdI'ag-bal, by means of a headed pin and slot, a device well'linown in this class of machines.

Each drag-har is provided with its cultivator-tooth lGr, pivoted at the top of its rear standard, in an open slot in the rearA end of the drag-bar, as shown at a,

,and having its forward standard operating in connection with a wedge, w, having a curved or concave rear edge, which drops between it and the front end of the slot, and serves to hold it so firmly that it will not turn back on its pivot in ordinary soil, but will yield without breaking, when in contact with any immovable obstacles. p

Heretofore, in machines of this class, it has been generally considered necessary to provide the frame with two stout beams, in addition 'to the beams AA', viz, one in front, to support and brace the tongue, and one in rear, .to support the drag-bars', or the standard and lever by which they are raised and1 lowered.

In this machine, the necessity for such beams is obviated, and the frame, while equally strong, is'rendered lighter and smaller, by stepping the tongue M in a socket, m, xed to the front side of beam A, and bracing it on each side, by means of oblique braces or hounds N N extending from the sides of the tongue,

just behind the team, across the upper edge of both beams A A', and to a point nearly over the lifting-bar F, as shown in the drawings, saidl brace-beams being bolted to the sides of the tongue, as shown at n n, and also to the cross-beams A A.

Additional metallic brace-rods I I may he employed if preferred, and the rear ends of the braces N N may bemade to support a tool-box, J, which will be con- Y venient in case of accident in the field.

The drag-bars may all be raised and lowered at once, by means of chains H extending from the bar F, up over segment pulleys K K, to one of which is attached a lever, L, said apparatus being all supported by curved standards O O, fastened upon the b racebeams N N,.near their rear end, and projecting upward and backward, as shown in iig. 2.

lhe two (or more) segment pulleys, are firmly xed upon a rockshaft, It, and a spring-pawl and ratchet may be employed, in connection with the lever, to hold the teeth at any desired elevation.

We would call attention to the fact, that the arrangement of th beams N N, in connection with the tongue and the cross-beams A A', enables us to dispense with any beam parallel to, and either in front or rear of the two cross-beams, for the purpose of snpporting or bracing the tongue or any other parts of the machine. This enables ns to makeV our machine lighter and more compact than any other now in use, without in the slightest diminishing its strength. It also brings the team nearer to the body of the machine, an obvious advantage when working in a fenced field, and it furnishes the strongest and best support for the standards O 0, besides providing a convenient and safe place for the tool-box J.

Having tlms described our invention, v

WVhat we claim as new, and desire to secure by Letters Patent, is-.-

1. In a seeding-machine, the construction and arrangement of the tongue M and brace-beams N N, in connection with the two parallel cross-beams A A', substantially as and for the purposes set forth.

2. In connection with the described arrangement of tongue, cross-beams, and braces N N, in a seeding-machine, the arrangement of the standards O O, which, support the lifting-chains and lever, upon the rear end of the braces, substantially as and for the purposes specified.

3. The means herein described forfasteningthe teeth G, viz, the wedge w, operating between thefront edge of the forward shank of the tooth and the front cndof the slot in the drag-bar, substantially as and for the purposes indicated.
