CHECK-LINE GUIDE FOR CORN-PLANTERS SPECIFICATION forming part of Letters Patent No. 241,358, dated May 10, 1881,

7 Application filed March 11, 1881. (ModeL) act description, reference being had to the ac companying drawings, making part of this specification, in Whichcheek-line guide. liig. 2 is a front elevation of one end of the guide orpivoted pullev-holder enlarged, showing the arrangement of the sliding sheave, and Fig. 3 represents a vertical sectionthrough Fig.2.

My invention relates to an im provement upon the pulley-holder or' check-line guide described in my patent of October 29, 1ST8,No.2tl!l,477; and it consists in a novel construction of the inner end of saidholder adjacent to the vibrating arm or fork which actuates the dropping mechanism, whereby the pulley mounted in said end isallowed an .endwise nmvement to accon'unodate the varying relation of the cheekline to said end consequent upon the vibration of said fork or arm, as hereinafter explained.

The pulley-holder constituting the cheekline guide applied to the ends of the main frame-bar of the check-row attachment is similar in its general construction to that described in my former patent referred to, and may be applied as therein described, orin an y ('onvenient manner; but the plates or parallel bars A A, between which the guidespulleys are mounted at their inner ends, have ofi'sets formed in them at a to, increasing the space between them where they cover the grooved guidingpulley B in such manner as to permit an endwise movement of the elongated shaft b of said pulley or sheave in its bearings in said bars for varying the position of said pulley, as indicated by the dotted lines, Fig. 2-tha-t. is to say,the soeketformed in and between the bars A A for the reception of the sheave adjacent to the vibrating arm or fork over which the cheek-line actuating the seeding devices passes is widened to pcrmitlat eral play of the pulley relative to said pulley-frame bars to accommowith concave sides, as shown at I) b", so that ,the bearings for its shaft b may project within the plane of said sides, and thus bring the supports of the shaft 11 as near as practicable to the slieave,\vhile permitting the desired move-- ment of the sheave relative thereto.

By this construction the sheave is allowed to slide up and down to accommodate the varying relation of the cord to the inner end of the pulleyholder, due to the movement or vibration in the arc of a circle of the fork or arm actuating the seeding devices and the slipping of the cord from side to side, and the consequent friction of the cord upon the sides of the pnlleydmlder is obviated and greater freedom and ease of movemen t of the cheek-line secured as the pulley which-is designed to obviatefrieto the movements of said line or cord.

Having now described my invention, 1 claim- 1. The pulley-holder forming the check-line guide. provided with the expanded socket for theshmive at its inner end, for permitting an endwise movementof saidpulley, substantially as and for the purpose set forth.

2. The pulley B, in combination with the. bars A A, provided with the expanded socket, permitting an endwise movement of said pulley, substantially as described.
