IMPROVEMENT IN Specification forming part of Letters Patent N0. 184,231,

CHECK-ROWERS.

dated November 14, 1876; application filed May 16, 1876.

To all whom it may concern Be it known that I, SAMUEL DE VEAUX, of La Fayette, Tippecanoe county, State of Indiana, have invented a new and useful Improvement in Check-Rowers, of which the following is a description, reference being had to' the accompanying drawings.

The object of my invention is to construct a check-rower and attach it to any ordinary corn-planter, so that the corn will be dropped at equal distances; and it consists of a frame, A, above which, near the center, is supported a sheave-Wheel, B, and rack-wheel O on the stud F. The rack-wheel O is attached to the sheave B, and is formed with a series of notches or cogs, g. These notches g are properly spaced, so as to allow the three arms of the regulator D to readily engage with any of will be hereafter described. The regulator D isalso pivoted on the stud F, and is held up, so that the-three arms are in gear with the wheel 0, by means of the spiral spring. U on the stud F, as shown. Each arm of the regulator D is'provided with a slot, E, in which is a bolt, S. This bolt S passes through the slots in the segments G G of the V-shaped adjustable eccentric J J. This V-shaped adjustable eccentric is formed of two wings, J J, hinged at the front at h, asshown. The segments G G are also secured to the wings J J in the manner shown in Fig. 2. By means of this arrangement I angle required, and at the same time adjust the extreme end' or point, as at hinge h, to any required distance from the center of the regulator D by means of the slot E and bolt S, as shown. There are three of these adjustable V-shaped eccentrics-one on each of the three arms of the regulator, and they are made to engage with the levers L L, to operate the feed-bar in the usual manner.

The wheel B is provided with a rope, P,

which passes once around the wheel, and is led onto and off of the wheel by guide-pulleys B R, attached to the frame of the machine in the manner shown.

When the wheel B is revolved by the rope P and movement of the machine forward, the regulator D, being held up in the cogs g, also moves around, and as each V-shaped cam J J sired, it is pressed down on the stud F and turned to any desired position, and then the spring U will holdit up in gear until it becomes necessary to again change it.

What I claim as new, and wish to secure by Letters Patent, is

1. In a check-rower, the combination of the sheave B, cog-rack G, three-armed regulator D, and stud F, constructed and adapted for the purposes described.

2. The adjustable V-shaped eccentric or cam, formed ofthe two wings J J, hinged at h, and the segments G G, all arranged to op erate in the manner shown, for the purposes specified and set forth. 7 3. In combination with the arms of the regulator D, the V'shaped eccentric J J G G, in the manner shown, for the purposes specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
