GEORGE W. ALTLAND, OF MOUNT TOP, PENNSYLVANIA.
Application filed April 9, 1885. (No model.)
To all whom it may concern:
Be it known that I, GEORGE W. ALTLAND, a citizen of the United States, residing at lWIount Top, in the county of York and State of Pennsylvania, have invented a new and useful In1 provemeat in Grain-Drills, of which th following isa specification.
The improvement relates to certain means of adjustably supporting the hoe or shoe of a grain-drill upon a wheel traveling in rear thereof, which wheel thus serves to regulate the penetration of said shoe or hoe, and also to press the ground over the grain after it has been dropped and covered. The improved device for this purpose is applicable to any kind of hoe, and may be readily removed from or attached to the same.
In order that the invention may be better understood, I will proceed to describe it with reference to the accompanying drawings, in which Figure I is a side elevation of a grain-drill hoe or shoe and supporting-wheel. Fig. II is a sectional elevation of the locking mechanism. Fig. III is a horizontal sectional view. showing the lower connection with the hoe.
1 may represent the hoe or shoe of a graindrill, having on the front at top lugs 2 3, the
lug Zbeing connected with the drill hoe or shoe in customary manner. The lug 3 is made in customary form; but instead of serving for the connection of the hoe to the drill-frame .form shown in Fig. III.
the standard is bent so as to bring the wheel directly in rear of the hoe and adapt it to press the ground over the grain as it is dropped and covered. In the upper lug, 9, of the bracket 5 is pivoted a cam-faced locking-lever, 12, adapted to press the front face of the standard 10 up against the bracket" 5, where its notches 13 engage with one or more teeth or projections, 14, to prevent relative movement of bracket and standard. This arrangement renders the adjustment of the hoe on the wheel-standard very ready, so that the depth of penetration of the hoe may be regulated according to whether the ground being planted is soft or hard, as when the ground is soft the penetration of the tooth will be limited by the wheel, and when the ground is hard the weight of the wheel, together with the shoe, will assist in cutting the furrow.
The point of attachment of the lifting-chain is preferably the top of standard 10, a hole being made therein for that purpose, as shown at 15. It is evident that the farther back the point of attachment is situated the greater is the leverage obtained upon the shoe or hoe and the easier it is for the operator to raiseit.
Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:
1. The means of attaching the wheel-standard to the hoe orshoe of a grain-drill, consisting of a bracket bar having suitable means of connection with the hoe at top and two-part clamp at bottom, substantially as described.
2. The combination, with a grain-drill hoe and bracket-bar fixed thereto,of a wheel-standard adjustable on said bracket-bar, and a camfaced locking-lever arranged to operate in connection therewith, substantially as described.
3. In combination with a bracket-bar having tooth or projection, as shown, a notched wheel-standard capable of adjustment on said bracket, and acam-faced locking-lever, as set forth.
