IMPROVEMENT lN GRAIN-DRILLS.
Specification forming part of Letters Patent No. 35,634, dated June 17, 1862.
To all whom it may conccrn:
Be it known that I, JONATHAN SMITH, of Tiffen, Seneca county, and State of Ohio, have in vented new and useful Improvements in Seed-Drills; and [do hereby declare the following to be afull, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, in whicht Figure 1 is a top View of hollow drill-tooth b with drag-bar, pin, and springj'when in op- Fig. 2 is a top view of the same. Fig. 3 is a vertical section of the same through the linew w of Fig. 1 when its point is thrown back by meeting with obstructions in its passage when in use.
The nature of this invention consists in so combining with the drag-bar and drill-tooth of seeding-machines wherein pins are used in the ordinary manner to'hold the drill-tooth in position a yielding spring, for the purposes hereinafter named, the construction and operation of the same being as follows, viz:
Drag-bar a is composed of two bars of iron, laterally arrangedand sufficiently wide apart toadmitthe upward-inclining projection d of drill-,toothb between them, and' to which they are attachedattheir inner ends by an iron pin or bolt, E, and with their opposite ends from their connection with spring f sufficiently spread for propenconnection with the front part of the framework of the machine. Between the bars forming the double drag-bars or, immediately in the rear of their forward expansion and firmly combined therewith, isa
metallic block or plate, H, provided with two or more holes for bolt B, for the purpose of adjusting springf, whereby the shovel or point of drill-tooth b may be thrown forward .or backward, thereby causing the seed to be deposited at greater or less depth, as desired. The rear end of spring f, formed of a thin steel bar of any desired width, is provided with a long slot, g, for thereception of projecting and downward inclining neck .9 of drill-tooth b, which I projecting neck 8 is provided with bearings 0,
which rest on the spring f at the sides of slot .gi'n snchposition as to form a partial deadlock between spring f and projection S of drilltooth b, so that more thanthe ordinary resistance of the earth when in use will be necessary to change the vertical position of tooth b in reference to the surface of the earth, and. at the same time allow extraordinary resistance at the lower point to throw bearings 0 forward on sprin g f through slot 9, and thereby reverse its inclination, and allow tooth b to pass over such resistance by turning on bolt E. The upward-curved projection d of tooth b is also provided with different holes a to receive a wooden pin, producing as varied the same effect resulting from the change of bolt B in block H. The spring f, being alone used for the purposes before named, might become useless by breaking, and thereby cause delay in the use of the machine, while by using the projection d, in combination with spring f, pins-can be at once inserted at a, and the immediate use of the machine be continued as before.
Havingthnsfully described the construction and operation of my invention, what I claim as my invention, and desire to secure by Letters Patent of the United States, is-- 1. In combination with springf and curved neck S of tooth b, or their equivalents, block H, placed between the bars forming drag-bar a, and provided with two or more holes for the purpose of adjusting the position of drill tooth or boot I), as and for the purposes set.
forth. a
2. I do not claim the spring f nor curved hook S as my invention, as those are wellknown devices; but I do claim, in combination with a seed-drill boot held in position or operated by a spring, providing said boot with suitable projections. and such projections with adjusting-holes and pin to retain the boot in position when in use in case said spring should by any means be rendered inoperative, as and for the purposes set forth.
In testimony whereof I have hereunto subscribed my name in presence of two subscribing witnesses.
