To all whom it may concern: H

Be it known that I, ELI M. LUsK, a citizen of the United'States of America, and a resident of Knox City, in the county of Knox and State of Texas, have made a certain new and useful Invention in Attachments for Seed-Planters; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 is a side view of the invention, as applied, with positions of parts, as adjusted in dotted lines. Fig. 2 is a side view of the invention alone. Fig. 3 is a detail plan view of the rear plow beams. Fig. 4 is a section on the line 4-4:, Fig. 3.

The invention has relation to seed planters, and is designed for regulation of the depth of the small coverer plows in rear, by the driver, .without dismounting from his seat.

The invention consists in the novel construction and combinations of parts, inafter set forth.

In the accompanying ing the invention, the numeral 1 designates a seed planter of the type wherein the see box is located in rear of the seat, said being placed well forward, over the main axle. The usual seed box 2, seat 3, main plow 4, small coverer plows 5 and seed chute or drill 6 are shown. The coverer plows 5 are carried at the rear ends of rearward extending frame arms 7, pivoted forwardly at 8 to the main beam, considerably in rear of the seat 3, and are adjusted by means of a lever 10, pivoted at its lower end at 11, close to the upper approximately horizontal ortion of the main plow beam, and having a connecting rod 12 for raising and lowering the arms 7 upon pivot 8. The adjustment is held by engagement of the pawl 13 of the lever with the teeth of the arc bar 14. cause of the position of the lever 10, as governed by the location of the seat 3, over the main plow 4, it is advisable to keep its lower ivotal end 11 well raised, close to the beam, well above the pivot 8, to avoid interference with the action of the plow. And in order to give a proper degree of movement to the coverer plows in their adjustment and to redated October 2O, 1914, Serial No. 793,926. Application for reissue v p 1915. Serial No. 18,413.

tain proper leverage by pi to the" lever 10 at a point 11, an upward extending frame arm 9 rigidly secured to the arm 7 near its free end, the connecting rod being attached to the upper end of this arm 9 and having an voting the rod 12 Y a close to the pivot angular relation of substantially 90 degrees to the lever 10. V

The vertical stems 5 of the coverer plows 5 are adjustably secured in seats of the pivotal arms 7 1n the usual manner, by means engaging any one of a series of perforations 5 of said stems, this adjustment in the present case serving to increase the range of adjustment of covered plows 5, from the seat, by means'of lever 15. The

connecting rod 12 is also adjustably secured to the upper end of arm 9, by means of a bolt 12 having engagement with any one of a series ofperforations12 of said connecting rod, said rod being thus capable of being secured in the proper angular relation to lever 15, previously stated. It is designed to provide an attachment having the advantages stated and which may be readily connected both to the pivotal arms 7, carrying the coverer plows, and to the plow beam. To this end the rack bar 14 is pro vided, preferably, with forward and rearward extending brace arms 14', adapted for connection at their free ends with the plow beam upon opposite sides of the rack, to hold it securely in place close to the upper approximately horizontal portion of the beam, and thetransverse bar 9 is provided with downturned ends 9, to embrace the arms 7 and perforated for the transverse bolt 9 the'upward extending arm 9 being rigidly secured to one of said downturned ends by pin 9 In this way, in making the connection, it is only necessary to bolt the rack bar 14 in place and to secure the transverse bar 9' to the arms 7;

Then the front plow is adjusted for depth, by operation of the lever 15, to turn the crank axle 16 in the usual way, the rear plows will be simultaneously adjusted for depth, the special adjustment of my invention allowing for this.

By the use of my invention, it is not necessary special or independent adjustment of the rear plows is to be made, time being saved in this way, and plowing in uneven ground being accomplished more satisfactorily.
