SPECIFICATION forming part of Letters Patent No. 305,679, dated September 23, 1884.

'Application filed January 29, 1884. (No model.)

have invented certain new and useful Irn provenients in Check-Bowers; and I do de- Clare the following to be a full, clear, and'eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying draw` ings, and to letters or figures of reference marked thereon, which form a part of this v specification.

Figure l of the drawings is a representation of a front view of my device. Fig. 2 is aplan view of the same. Figs. 3, 4, 5, and 6 are detail views.

This invention has relation to check-rowers for seedplanters; and it consists in the construction and novel arrangement of devices hereinafter set forth, and pointed out in the claims appended. l.

In the accompanying drawings, the letter A designates the transverse bar of the frame, having the end pieces or arms, B, which are braced to the main bar by means Vof the irons C. Each arm B carries at one end a guide-pulley, D, and at the other enda guide pulley, E, for the iield -cordL Each arm B also carries a bearing, F, underneath for the transverse shaft G, which extends under the main bar A, and through a center bearing or hanger, II, extending downward from said bar.

On each end of the `shaft G is rigidly secured the large grooved wheel K, under 4o with radiallyextended arms a, arranged inV which the eld-cord passes, engaging its under portion. This grooved wheel is provided pairs at diametrically-opposite portions of its diameter, and serves to engage the knots or obstructions ofthe eld-cord as the planter moves over the field. i

L represents a short lever-arm, which is pivoted to a bearing of the mainl bar at b, and is designed to engage the seed-slide. This arm is slotted at c to receive an adjustable eyebolt, d, to which is attached a connecting- 5o rod, e, which extends to a slide-bearing, f,

which is seated in an arc-slot, g, in the upper adjustable section, h, of a pivoted swinging regulator, M. The section h is slotted, andis secured to the arm 7c of the regulator M by means of a bolt and nut. Suitable adjustable stop-screws, Z, are provided to project into the ends of the arc-slot g, as shown in the drawings. The regulator is pivoted to the central hanger, H, which depends from the main bar, and below the pivot are cam-shaped arms or wings m, extendingllaterally, as shown in the drawings.

On the stem l? of the swinging regulator is a weight, w, which is adjustable, and is se.

cured in position, after adjustment, by the setscrew o.

On the shaft G, at each side of the central hanger, H, is secured a head, t, carrying a projecting arm, s. These arms-which extend at right angles and in opposite directions from the shaft G, are of sufficient length to engage the respective lateral wings of the swinging regulator as the shaft revolves. As the planter moves over the field, the shaft is caused to revolve by the field-cord, which engages Athe grooved wheel atthe end thereof, and as the arms s are set in the shaft in such position that when the wheels K are turned to bring their knot-engaging arms a into vertical position the shaft-arm s will be horizont-al, and ono y of said arms, s,will be engaged with one of the wings of the swinging regulator M. This position will be maintained until the arms a of the grooved wheel engage a knot or obstruction of the field-cord, when the shaft will be turned, vibrating the regulator and throwing the lever-arm L and the seed-slide to which it is connected.

Having described this invention, what I claim, and desire to secure by Letters Patent, IS`
