INVENTOR l ATTORNEY IMPROVEMENT IN PULL-evs' F'i HK-lwca Specication forming part of lletteis Patent No. dated application i August S5, 1877.

To all whom it may concern:

Be it known that I, GEORGE D. HAWORTH, of Decatur, county of Macon, State of Illinois, have invented certain new and useful Improvements in Pulleys for Check Row Cords, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a plan view of the pulley-holder, showing my improvements applied. Fig. 2 is a similar view, with the pulley turned for receiving the cord in the opposite direction to that shown in Fig. 1. Fig. 3 is a side elevation of the same 5 and Fig. 4 -is a perspective view of the outer end of the swinging guiding-arm, showing the rollers at the entrance of the same.

Similar letters of reference denote corresponding parts in all the figures.

My invention relates to an improvement upon the pulley-holder described in Letters Patent granted to me January 14, 1873, reissued July 18, 1876, No. 7 ,234; and consists, rst, in the combination, with the semimevolving pulley-holder, of a swinging guide or arm for directing the cord to the pulley or sheave mounted in said pulley-holder; second, to the combination, with said pulley holder, of a guiding sheave or pulley mounted upon its inner end for guiding the cord from the main sheave or pulley to the actuating arm or arms of the check-rowing devices 5v and, lastly, to certain details of construction hereinafter eX- plained.

In the accompanying drawings, A represents the bar which is usually mounted on the front of the corn-planter, and to which the check-rowing attachments are connected; but my invention being coniined to the devices for directing the check-row cord or wire to the guiding-pulleys and to the check-rowing attachments, only so much of said bar is shown as is necessary to illustrate my invention.

Upon the outer end of this bar is mounted an upright standard or pivot-block, B, provided with a horizontal pin or pivot, b, upon which the pulley block or holder is mounted.

D is the pulley block or holder, made in two parts, d d, which are connected together by means of pins or bolts e e', the bolt e also serving as a pin or pivot for the sheave or pulley E, which is mounted in or clasped between the parts d d of said block. The part d of the pulley-block has cast with or otherwise connected to its inner end an arm, F, which extends inward, and is provided on its inner end with a vertical pin or pivot, f, upon which is mounted a small guiding sheave or pulley, G, said pulley serving to guide the cord from ,the main sheave or pulley E to the check-rowing devices.

H is a swinging guide or arm, composed of the head h and arms h, the arms h1 being connected to the pulley-holder D by means of pivot-pins h2, and cast upon or otherwise secured to the outer faces of the parts d d.

The outer ends of arms h1 are connected by the head h, which is made in the form of a short sleeve or eye, through which the checkrow cord passes, and by means of which said cord is guided with precision to the pulley E, imder the varying angles of the path of the machine, to the line of the check-row cord. This sleeve is provided on one sidewithaslot, i, made in the curved or irregular form shown in Fig. 4, which, while it permits the cord to be placed in the eye or loop by hand, prevents its accidental displacement when the machine is at work. Y

The expanded ends h3 are provided with pins K, placed at right angles to the arms hl and at the entrance to the loop or eye h, and upon these pins are mounted rollers 7c k, between which the cord or wire moves.

The extent' of movement of the arm H is regulated by means of a pin, H', on the part d of the pulley-block. The manner of connecting the cord is as follows: The cord being anchored in the usual manner, it is rst placed in the eye or loop h, through the slot t', and then passed around the pulley E, and thence over the pulley G to the check-rowing,r devices, and to a similar guiding device upon the opposite end of the bar.

It will be seen that b v this constructionof guiding device the cord is always held in proper relation to the pulley, and is directed therefrom with the required precision to the check-rowing devices.

Having novsr described my invention, what I claim as new, and desire to secure by Letters Patent, is i 1. The combination, with the pulley-holder, of the laterally-vibrating guide or arm, sub- Y stantially as sind for the purpose described.

2. The laterally-swinging guide or arm H, pivoted to the pulley-holder, and provided with the rollers 7c 7c at its outer end, substantially as described. y

3. The combination, with the pivoted pulleyholder, of a secondary guiding sheave or pulley, G, applied to said pulley-holder, and opA erating substantially as described.

4. The combination, with the pulley-holder i D, of the pivoted guide or arm H, a-nd the secondary slieewe or pulley G, attached to seid holder, substantially as and for the purpose set forth.

GEORGE D. HAWORTH.
