IMPRovEMENT INSEEDING-MACHINES.

Specification forming part of Letters Patent No. 59,639, dated November 13, 1866; reissue No. 6,726, dated November 2, 1875; application filed May 10, 1875.

To all whom it may concern:

Be it known that I, WoaDEN P. PENN, of Belleville, St. Clair county, State ot' Illinois, have invented Improvements in Seeding-Machines. The following is a full, clear, and eX act description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a longitudinal section of the frame of a seeding-machine having my improvements applied to it. Fig. 2 is a longitudinal section of a seedingmachine, showing a modilication in construction. Fig. 3 is a top view of Fig. l. Fig. 4L is a bottomview of the hopper, showing the adjustable seed-discharg ing slides. Fig. 5 is a perspective view ot' a tooth attached to a drag-bar. Fig. 6 is a top view of the hopper. Fig. 7 is a top View of the seed-plate a. Fig. 8 shows a top view of the several plates b-one for each seed-outlet.

Similar letters of reference indicate corresponding parts in the several figures.

My improvement relates mainly to a novel method of applying the teeth of seeding-machines to a swinging transverse beam by means ot' bars, as hereinafter described. Y

To enable others skilled inv the art to make and use my invention, I will describe its construction and operation.

In the accompanying drawings, A represents the frame of the machine, which may be constructed in any suitable manner, and which is mounted upon transporting-wheels B B. Upon this frame A, and extending transversely across it near the axle-tree B', is a hopper, C, which is to contain the seed for distribution. The bottom of this hopper is composed of several plates, et b c. (Shown in Figs. 2 and 4.) The plate c which is nearest the seed in the hopper, or which is the uppermost plate, is perforated at suitable intei-vals along its length, which pert'orations are oblong, but somewhat in the form of the letter L-'i. e., one portion'oi' the width of each opening is greater than that of another portion, as shown in Fig. 4. Plate a is longitudinally adjustable with respect to the hopper, and may be adjusted by a screw or otherwise. Beneath the plate a are several plates, b, having rectangular oblong openings through them, as shown in Fig. 4, and beneath these stationary plates b b b is a sliding plate, c, also shown in Fig. 4, which is supported by the straps e e, and which is of sutcient length to close the openings through the bottom ofthe seed box or hopper C, when this plate is moved back or forward, as the case may be, beneath said openings. The slide c serves the purpose of a cut-ott' for said openings, and it may be adjusted in any convenient manner.

By means of the abovedescribed combination oi ixed and movable plates, constructed as shown, and applied to the bottomot'a seedbox, C, I obtain a small square or rectangular opening, or an oblong opening, with'one part ot such opening wider than the other part, and by this means the width, as well as the length, of the openings ot' the plate a is varied according to the size ot' the seed or the ilow required. The holes of plate a are disposed or arranged so that the decreasing offsets of the holes alternately comeon oppo site sides of the vertical axis of the hopper. The arrangement of the plates and form of the holes therein enable me to exercise 'control over the discharging-mechanism for the seed', and to effect a rapid or slow flow of the seed, as circumstances require.

The agitator D consists of a shaft which extends through the hopper C in a direction with its length, and which is provided with a number of projecting pins for stirring the seed in said hopper, and causing them to ilow through the discharge-openin gs. This agitator D may be rotated or oscillated by gearing communicating with the transporting-Wheels. The arrangement of the spurs or pins in said agitator D may vary according to the motion which is given to it. After leaving the hopper C, the seed is conducted into a trough or chute, f, which is formed on or rigidly applied to the upper end of the tooth E'. In practice, a number of such teeth will be employed, corresponding to the number of discharge-openings in the bottom of the hopper.

In Figs. 1 and 3 I have represented a tooth, E', connected to a short bar, N, which is pivoted at its forward end, in any suitable manner, to a swinging transverse beam, P'. This PATENT Grt-Ion swinging transverse beam` P' Ais connected to' the frame, forward of the aXletree B', by means of arms P P, which are pivoted at their forward ends to the longitudinal beams of the frame A, in such a manner thaty the trans- -V the employment of' a swinging-beam, P', connected by arms P with frame A, and attaching the teeth to said swinging transverse beam P' by the bars N, a considerable amount Y of iron is saved inthe construction of a seeding machine, and still all the teeth can have independent action, by means of their pivotal connections, with the swinging transverse `beam P', so that' one tooth can rise and pass over irregularities ot' the ground Without'lit't-l ing the others out of working position. lAll ofthe teeth have their support upon the swinging transverse beam P',vv by means of bars N pivoted to said'beam, and, consequently, when beam P' is elevated or depressed the teeth will receive a corresponding movement.

' I ,Theehute f may be supported at or near its forward end by means of .a standard, g, secured to a brace, g1,eonnecting the upper end 'lot' the tooth E' to 'the drag-bar F, as shown in '.Figs. 2 and 5. At an intermediate point between the ends of the tooth E', the rear end of thedrag-bar F may begpivoted to this tooth. -The diagonal brace g may be arranged above the drag-bar, and` pivoted both to this bar and to the tooth,so as to constitute an upper brace, andr also a support for the for-y ward or upper end of thechut-ev f. Holes may Vbe made through the drag-bar F, near the forward end ot' the brace g1,`for theA purpose of'l enabling one to adjust the tooth and set it at vdiii'erent angles. It' desirable, a wooden pin, g2, may be used, which will break, and prevent the tooth or its appendages from beting injured should the pointy-of this tooth n meet with any great obstruction in its path.

The drag-bar f may be pivote'd to the forward cross-beam of frame A, so that the tooth may rise or fall and accommodate itself to an uneven surface as' the machine isv moved along, andalso so `that the tooth maybe elevated free from the ground whenever it is desired. The rocking beam Gr, which extends transversely across the frame A, in the rear of the hopper G, is attached to the teeth E' by means of chains or straps h, and when this beam is. moved upward it willelevatethe teeth. A handle or lever or other contrivance may be applied to said beam, for the purpose of enabling the attendant to move it and retain it in the desired position. The teeth E' may be constructed with openI bottoms, in Vthe usual manner of making teeth for seedingmachines, and they may be made of thin metal,.fashioned in the tubular/form represented in Figs. 2 and4, or they may be made of cast metal. Y n

Having thus described my invention, what I claim as new,and`desire to secure by Letters 'Patent, is

1 'Theswingng transverse beam P', with 'the bars N thereto attached, in combination withl the frame A and arms P P, substantially as specified, for the purpose ot' carryingthe forward ends of the bars N, as specified.

f 'WORDEN P. PENN.
