SPECIFICATION forming part of Letters Patent No. 434,292, dated August 12, 1890. I

' Application filed December 5, 1889. Serial No. 332,617. (No model.)

manufacturer of agricultural implements, of

the town of Ingersoll, in the county of Oxford,

in the Province of Ontario, Canada, have invented a certain new and useful Improvement in Seeding-Machines, of which the following is a specification.

The object of the invention is, first, to construct that portion of the frame from which the drag-bars are suspended in a simple, cheap, and light manner; secondly, to provide easy means for adjusting the drag-bars to bring them closer to each other or farther apart, in order to enable the drill-rows to be made any desired distance apart, and, thirdly, to provide simple means for adjusting the teeth or hoes on their drag-bars to any desired angle to regulate the depth at which they will enter the soil and it consists, essentially, first, of a drag-bar shaft connected at each end to the axle-bracket by two barsone extending horizontally to the base of the axle-bracket and the other diagonally to an arm extending from the said brackeP-the said shaft being journaled in a bracket fixed to the bottom of the tongue; secondly, of dragbar clips fitted onto a drag-bar shaft having a longitudinal groove formed in it to receive a rib formed on the journal surface of each clip, in order that the said clips may be independently adjusted longitudinally upon the said shaft and at the same time be held from revolving on it, and, thirdly, in the peculiar formation of the drag-bar head and projections extending from the drill-hoe or cultivator-tooth by which the angle of the said drillhoe or tooth may be readily adjusted without removing a bolt.

Figure 1 'is a perspective view of that portion of the frame to which the drag-bars are connected. Fig. 2 is a detail of one of the dragbar clips. Fig. 3 is a perspective view of the drag-bar head and top of the drill-hoe or cultivator-tooth. Fig. 4 is a sectional elevation of the same parts. Fig. 5 is a detail of the mechanism for locking the dr ll-hoe or cultivator-tooth in position. Fig. 6 is a detail of lifting-chain connection.

A is the drag-bar shaft supported at each end by two bars B and C, the bar '13 extending horizontally to the-bottom of the axlebracket D, while the bar 0 extends diagonally to an arm E, projecting from and formed upon the axle-bracket D, thus constituting a strongly-braced support for each end of the drag-bar shaft A. A bracket R, fixed to the bottom of the tongue S, forms a bearing for the center of the shaft A, and midway between this counter-bracket and the ends of the shaft A, I preferably provide stiffeningbars T.

With the view of enabling an easy longitudinal adjustment of the drag-bars F, I make a longitudinal groove to in the drag-bar shaft A, and on the journal surface of each dragbar clip G,I form a rib b to fit into the groove a. When the nuts H, which hold the cap of the clip in position, are tightened, the said clip G is held rigidly to the drag-bar shaft A, and by loosening the said nuts the said dragbar clips may be independently adjusted longitudinally upon the drag-bar shaft A, and held in any desired position by simply retightvening the said nuts. Of course the same effect will be produced by making a rib on the dragbar shaft or making the drag-bar angular in cross-section, in order to prevent the oli p from revolving on the d rag-bar shaft, while permittingit to be adjusted longitudinally. By thus making the drag-bar clips adjustable upon the drag-bar shaft the drag-bars may be moved closer to each other or farther apart,in order that the farmer may readily adjust the drill hoes or teeth of his machine to make the drillrows any desired distance apart. The hand-' lever I is suitably supported on a bracket fixed to the tongue of the machine, and is connected by the rod J to the crank K, which is fixed to the drag-bar shaft A. It follows, therefore, that the movement of the hand-lever I will cause the drag-bar shaft A to revolve, and as the drag bars are alternately connected to their respective clips on opposite sides of the drag-bar shaft A the rolling of the said drag-bar shaft will cause the desired zigzagging of the teeth or hoes. As the shaft A cannot be raised or lowered for the purpose of altering the angle of the teeth or hoes, it is necessary that the teeth or hoes should be connected to their respective dragbars in such a manner that their angle may be readily altered. This I accomplish in a simple manner and without the necessity of removing a single bolt. On reference to Sheet 2 of the drawings the details of construction of this portion of my invention will be found fully illustrated.

L is the dragbar head pivoted on the end of the drag-bar and held in position by the spring-dog M. A notched projection N extends from the top of the head L, and from the base of this projection the face of the head is shaped, as indicated, to receive the faces of the projections O P, formed 011 the head of the drill-hoe or cultivator-tooth. The projection O is shaped, as indicated, to fit into any of the notches d, formed on the projection N, while the projection I is merely the base of the T-bolt Q, which is designed to fit into an elongated slot U, formed in the drag-bar head, as indicated. In order to insert this T-bolt Q in the said slot, it is necessary to turn the tooth or hoe in a horizontal position, and when it resumes its normal position the T-head of the said bolt Q extends across the slot and holds the projection P against the head L. \Vhen the T-bolt Q, is inserted in the slot U and the tooth or hoe swings around to resume its normal position, the springbolt V is held clear of the slot U by the hand, so as to permit the T-bolt Q to be at or near the bottom of the slot U, in order that the projection 0 may clear the lip (6', formed on one side of the notched projection N. \Vhen the tooth or hoe is adjusted to the desired angle, it is raised up, so as to force the projection 0 into the desired notch in the projection N, which will hold it in the said position. spring-bolt V springs out under the T-head of the bolt Q, thus locking the said bolt and preventing the projection 0 from falling out of its notch. From this description it will be seen that it is merely necessary to push the spring-bolt V clear of the T-head of the bolt Q, when the projection 0 may be dropped clear of the notched projection N and moved so as to come opposite to the particular notch which will hold it in the desired new position.

\Vith the view of providing simple means for the purpose of detachably connecting the lifting-chains to their respective drag-bars, I form upon the drag-bar head L an arm \V, which extends back onto one side of the drillhoe or tooth-head. On the side of the arm IV next to the face of the tooth or hoe I form a fork X, into which one of the links'of the chain Y is inserted. In order to retain the chain in this fork, I form a flange Z on the face of the hoe or tooth head, which projects over the forked end of the arm \V when the tooth or hoe is fixed to the drag-bar head L.

Then thus raised up, the

lVith the view of permitting the easy rocking of the head of the tooth or hoe while being adjusted to the diiferentangles, I convex the face of the projection N, or that portion of the drag-bar head L against which the said projection fits,or I may convex both the said surfaces.

With the view of preventing the lateral movement of the projection O in the slot, I can either provide the lip cl, already described, on one side of the notched projection N, orI might place them on both sides, or instead of the lip being formed on the notched projection N a lip could be formed on one or both sides of the projection O.

I have spoken of the bolt Q as being T- headed. It will of course be understood that an L-headed bolt would answer quite as well. In fact, a bolt with a head of any form which will prevent it passing a slot made to receive its shank would answer. If I used a roundheaded bolt, I would of course have to make a round hole near the bottom of the slot U. All the other parts would work exactly the same, except that it would not be necessary to turn the hoe or tooth in a horizontal position in order to form the connection between it and the drag-bar head.
