GEORGE D. IIAWVORTH, DECATUR, ILLINOIS.

SEED-PLANTER.

SPECIFICATION forming part of Letters Patent No. 283,782, dated Angust28, 1883.

Application filed March 8, 1883. (No model.)

T0 aZZ whom, it may concern:

Be it known that I, GEORGE D. Hnwon'rn, of Decatur, county of Macon, and State of Illinois, have invented a new and useful Improve ment in Seed-Planters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to the means for actuating the intermittingly-rotating seed wheel or disk, and for locking and holding it in the intervals between its movements; and it consists in the combination, with the seed-slide or sliding bar, through which movement is imparted to the seeding wheel or disk, of projecting spurs for actuating the rocking crosshead, and pawls which act upon the seedwheel, and of iother spurs which at each end of the throw of the seed-slide serve to stop and lock the seed-wheel.

It further consists in the combination of the spurs for actuating the intermittingly-rotating seed disk or wheel and the spurs for stopping and locking said disk in a single pieceor casting, and in a novel construction and arrangement of the pawls through which the intermittingly-rotating movement is imparted to the seeding-disk, and of spurs on the seed-slide acting in connection with said pawls, whereby rebound of the latter at the end of their operative throw is prevented, as hereinafter explained.

In the accompanying drawings, Figure 1 is a rear elevation of one of my improved seeddistributers, with the seeding -wheel casing partly broken away to show the relation of the wheel-actuating devices to said wheel. Fig. 2 is a side elevation of the distributer-wheel and an end elevation of the plate or casting on the seed-slide for actuating and stopping and locking the intermittinglyrotating disk or wheel. Fig. 8 is a bottom view of the spurred casting actuating the seeding-disk and a portion of'the seed-slide to which it is attached; and Fig. l represents one of the pawls through which the seeding-disk is operated, in side and rear elevations.

The seeding'whecl, in the general features of its construction, and the shell or casing and hopper, in connection with which said -wheel operates, are similar to the corresponding parts described in Letters Patent-granted to me June 14, 1881, and said parts will therefore not be described in detail herein beyond what is necessary in explaining my present improve" ments.

In the drawings, A represents the distributer-wheel casing, and B the distributingwheel or disk, said parts, as above stated, being,

similar to the corresponding parts described in my former patent referred to, and being in practice applied, in connection with the seed box or hopper, in a similar manner. The seeding wheel or disk is made in two parts, each with a circle of laterally projccting teeth, and one, B, with slots'orperforations between its teeth, through which perforations the teeth of the other disk pass, )rojecting more or less between the teeth of the first, for gaging or regulating the capacity of the seed-cups formed by and between the teeth and .casing, as ex plained in my former patent referred to. The wheel Bis extended beyond its circle of teeth Z), and the extended rim or flange (indicated at B) is scalloped to form a circle of spurs or teeth, I), of the form substantially as shown in Fig. 2, the outer ends of which are expanded in width and made concave on their outer faces or ends, as shown at 11*. An intermittent rotating movement is imparted to this seeding-wheel by means of two upright pawls, E and E, set facing each other on opposite sides of the disk, and pivoted at their lower ends to the opposite ends of a rocking bar or lever, F. The upper ends of these pawls E and E are provided with inwardly-projecting spurs or teeth 6 and e, which enter the space I) between the teeth I) of the wheel B, and serve alternately, as the pawls are rocked upward, to impart an intermittent rotating movement to said wheel. The lower faces of these teeth are inclined to adapt them to readily ride out ward on the advancing tooth below it as said tooth is being propelled by the opposite rising pawl. The pawls E and E are provided, just above their pivotal connection with the rocking bar F, each with a horizontal oiiset or shoulder, 6 for a purpose which will be explained. The rocking lever F is mounted centrally of its transverse length upon a longitudinal shaft or pivot, F, having any suitable point of support, either in the upper end of the seeding-tube A or lower end of the cas- 7 ing A, communicating with said tube, and is provided above said pivot with an upright bifurcated arm, E the projecting arms or spurs Fig. 3 in lower face elevation.) This plate D is socketed to receive the end of the sliding bar D, to which it is secured, and is provided on its lower face with a horizontal forwardly- 1 5 projecting tongue, D arranged centrally of its length and projecting between the arms f and f of the .rocking lever F, and at its ends with downwardly-projecting spurs d and d, arranged outside of the arms f and f, and serving, in connection therewith and with the tongue D as the bar D is reciprocated, to impart a rocking movement to the bar F, for causing the pawls E and E alternately to act on the seeding-wheel. 2 5 In addition to the function described, the spurs d and d act alternately, one, d, on the shoulder e to prevent rebound or outward throw of the pawl E as it completes its upward throw, and the other, d, acting in a similar manner on the shoulder of pawl E, said shoulders being brought alternately up into contact with the lower ends of said spurs.

The plate D is further provided on its rearward face, at its upper edge, with rearwardlyprojecting spurs d and (1, one at each end, which, as the slide is reciprocated alternately, enter the concavities b in the outer faces or ends of the teeth b of the wheel B, as shown in Fig. 2, serving to stop the movement of the wheel at the end of the throw of its operative pawl, and to lock said wheel against further movement until by the movement of slide D in the reverse direction the opposite pawl is set in motion and the locking-spur d or d withdrawn.

Back of the spurs d and d, on the upper face or edge of plate D, is an upwardlyprojecting rib, (1, extending lengthwise of said plate, and of a length slightly greater than the length of throw of said plate and bar, and which engages with a lip on the casing A for steadying and guiding the movements of said plate and for holding it in proper working relation to the seeding-wheel and its actuating devices, 55 described.

By the construction described, the plate D .tially as described.

is made to perform not only the functions of the rack described in my former patent referred to for actuating the seeding-wheel; but

in addition thereto, the function of the detached stopping and locking devices therein described, thereby greatly simplifying and reducing the cost of cgnstruction.

The-form of the parts may of course be varied, but those described and shown have been found to work satisfactorily in practice.

Having now described my invention, what I claim as .new is 1. The plate D for actuating the seedingwheel, provided with the tongue D and spurs d and d, substantially as and for the purpose described.

2. The rocking bar to which the pawls actuating the intermittingly rotating seeding wheel are pivoted, provided with a bifurcated arm, in combination with the spurs on the re ciprocating plate D for actuating said arm and rocking bar, substantially as described.

3. The pawls E and E, pivoted to the rocking bar F, and provided with the shoulders 6 in combination with the spurs d and d on the reciprocating slide D, substantially as described.

4. The teeth of the distributing wheel or disk, notched or provided each with a concavity on its outer end, in combination with spurs on the reciprocating slide for engaging said teeth and locking the wheel, substantially as described.

5. The plate D, attached to the seed-slide D, and provided with the spurs D, (l, andd for actuating the seeding-wheel, and the spurs d and d for holding said wheel, substantially as described.

6. The socketed plate D, provided withthe spurs D d, d, d, and d and the guiding rib or flange d*, made in one piece, substantially as described.

7. The combination, with the seeding-wheel B, of the rocking bar F, provided with the bifurcated arm F, the shouldered pawlsEand E, and the plate D, attached to the slide D, and provided with the spurs for alternately actuating and locking said wheel, substan- In testimony whereof I have hereunto set my hand this 5th day of March, A. D. 1883.
