SYLVESTER I-I. JONES, OF RIGHMOND,'INDIANA, ASSIGNOR TO THE HOOSIER DRILL COMPANY, OF SAME PLACE.

SEEDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 591,354, dated October "5, 1897.

' Application filed May 8,1897. Serial No. 635,657 (No model.)

To all whom it may concern.- Be it known that I, SYLvEsTER H. J ONES, residing at Richmond, in the county of Wayne and State of Indiana, have invented certain new and useful Improvements in Seeding- Machines, of which the following'is a specification.

My invention relates to improvements in seeding-machines, and especially to that class which employ a rotary disk for opening the furrow.

One of the objects of my invention is to so construct the disk, its supports, and attachments that any number may be united and be made independent of each other upon a single machine. 1

Another object of my invention consists in a novel method of applying pressure to several furrow-openers simultaneously, so as to regulate the depth of the seed-planting.

Another object of my invention is to provide suitable grain-delivery tubes to work in, conjunction with the disks to assist in preparing the furrows as well as to depositthe seed therein.

Another objectof my invention is to provide means forjournaling the disk upon dragbars by means of hangers so that the drag bars are elevated above the center of the disk, thus allowing a-smaller disk to be employed.

Another object of my invention'is to provide means for supporting a disk in a frame with attachments for preventing the same from clogging, and also to provide means to prevent dirt from getting into the journalbearings of the disk.

The various features of my invention are more fully set forth in the description of the accompanying drawings, making a part of thisspecification, in which- Figure 1 is a side elevation of my improvement in positionfor use. Fig. 2 is a top plan view of Fig. 1. Fig. 3 is a side elevation, the reverse of Fig.1, with the pressure devices connected thereto. Fig. 4: is a horizontal section of the diskand its journal-supports.

A represents the main drag-bar attached to any ordinary seed-drill frame. I

a represents an auxiliarydrag-bar connected to the main drag-bar A by sleeves b and bolts 0.

B represents the seed-tube,v provided with an ear d, to which the drag-barAis attached and rigidly secured by bolts, as shown in Figs. 2 and 3.

D'represents hanger-brackets, one of which is attached tothe drag-bar A and the other to the auxiliary drag-bar a. They depend downward therefrom and are provided with socket-shaped bearings e, as shown in Fig. 4. E represents the disk of the ordinary concave form.

F represents a sleeve or cylinder provided with an annular flange f., I

The disk E is pierced with a central opening to receive the cylinder F, and the parts are secured together by rivets passing through the flange f and the inner periphery of the disk. This sleeve journals on a sectional hub of. hangers D, and the ends of sleeve F each engage in a socket or annular recess formed in the hub of its respective hanger D. Bolt 1" clamps the hangers D together, the ends of the sectional hub meeting Within sleeve F. It will be observed that this disk is journaled obliquely to the line of travel of the drag-bar A, which obliquity is determined by the attachment of the hanger-brackets to the drag-barsAa. This socket form of journal is very advantageous in keeping the dirt from working into the j ournal-bearings. This method of suspending the center of the disk belowthe drag-bars allows very much smaller disks to be used and yet maintains the dragbars at the proper height. 1 By terminating the drag-bar a at the axis of the disk it leaves an opening on one side at the rear of the disk which prevents the frame from being clogged by the accumulation of dirt carried up by the disk. e

In order to more effectually keep the disk clean, I attach a steel scraper H to the hangdeposited into the furrow, so that it may be properly covered.

B represents the seed-tube, which is made strong and forms the base for the attachment of the supporting parts. It projects considerably above the disk, and its lower end terminates adjacent to the lower rear edge thereof. To this end is attached the f urrow-opener I.

(1 represents the ear to which the drag-bar A is rigidly connected.

i represents the ear to which the supportin g-bars of the covering-wheel K are hinged.

L represents a coil-spring supported upon a core 1, said spring seating against the drag bars 71, at one end and the arm Z of the seedtube at the other end. It is strained in the ordinary manner, so as to regulate the pressure of the covering-wheel.

By this construction of the several parts various advantages are obtained. I am enabled to use elevated drag-bars, which are rigidly attached to the seed-tube as a base, and the strain on the seed-tube is counteracted by the strain of the drag-bars and compressing-spring on the opposite side of said seed-tube, thereby sustaining the seed-tube by a bracing action of these parts against the strain of the furrow-opener I on the lower end. I am thus enabled to make a very light but strong seeding device.

In order to control the depth of the furrows, I provide the following means:

M represents a hollow tube in which is placed a coil-spring m.

Nrepresents a rod or plunger passing down inside of the spring 071.

n represents pins or lugs attached to the plunger-rod N, which project through slots 0 of the tube M, so as to allow a vertical travel of the plunger, the spring seating between the base of the tube M and the pin 91. The tube M is secured to the drag-bars in front of the disk at the base, and the upper end of the'plunger N is pivoted to the crank-arm P, which journals on shaft Q.

Itrepresents a setting-lever for shifting the crank-arm P on the shaft Q.

0- represents a lock-lever engaging with the teeth of segment S to hold the setting-lever in any desired position.

It will be seen that by rocking the crank P on shaft Q the plunger N will be moved up or down to regulate the tension of the spring, and hence the pressure on the drag-bar A and disk E. It will be observed that by this method of connection a series of drag-bars and disks could be simultaneously controlled by providing each with its own tube and plunger and cranks P operated by a common lever R, and yet each disk would yield to undue pressure and pass over a hard substance or obstruction without affecting the remaining disks of the series.

It will be observed that each of the coverin g-wheels K would be free to pass over 0bstructions by the compression of the spring L independent of the others.

The ordinary lifting attachments are not shown. They may be attached in the usual manner to the heel of the seed-tube.

If desired, the disk E and curved plate I may be made of straight or plain faces instead of curved and accomplish the same results, but the form shown is preferred.

As the means herein shown for supporting and journalin g the rotary disk allow a much smaller disk to be employed than those universally used, the furrow made by said disk is consequently much narrower than the common furrow. Hence the furrow-opener I, attached to the seed-tube, is a very important feature of my invention.

It is very desirable to use thin sheet metal from which to form the disks. It should also be supported by journals upon both sides, between which the disk is clamped.

The form of construction herein shown and described is deemed important in securing both lightness and strength.

Having described my invention, I claim 1. In a seed-drill the combination with the drag-bars rigidly connected to the seed-tube of the disk journaled between hangers attached to and depending from said drag-bars and at an angle to the line of the travel, substantially as specified.

2. In a seeding device the combination with a main drag-bar attached to the seed-tube and an auxiliary drag-bar connected to the main drag-bar and terminating near the axis of a seed -disk journaled to said drag-bars by means of depending arms which clamp the ends of the disk-journal, substantially as and for the purpose specified.

3. In a seed-drill the combination of a main drag-bar attached to the seed-tube by the brace-ear d, and an auxiliary drag-bar rigidly secured to the main drag-bar, the depending disk-hangers D rigidly secured to said drag-bars, the disk E provided with the cylindrical support F and flange f, and means for clamping the said cylindrical support between the ends of the dependent hangers, substantially as specified.

4. In a seeding-machine the combination with the elevated drag-bar rigidly secured to the seed-tube, of the supporting-bars 7a hinged to the rear side of said seed-tube and the furrow-opener I rigidly secured to the lower end of said tube and adjacent to the disk E journaled to dependent hangers, substantiallyas specified.

5. In a seeding-machine, the combination of an elevated main drag-bar rigidly secured to a seed-tube, an auxiliary drag-bar rigidly secured to said main bar, and terminating near the axis of the seed-disk, a seed-disk journaled to said drag-bars by means of dependent hangers, and the scraper II secured to the rear end of said auxiliary dragbar,substantially as specified.

6.77111 a seeding-machine, the combinationwith the drag-bars and a seed-tube rigidly attached thereto, of hangers depending from the drag-bars, a disk journaled in said hangers, a furrow-opener rigidly secured to the lower end of said feed-tube, a tube connected at its lower end to the drag-bars, a coiled spring arranged in the tube, a plunger-rod movably arranged in the tube and bearing against the upper end of thespring, and-a straining shaft and lever for vertically adjusting the plunger in the tube to regulate v the tension of the spring to control the depth of the furrow, substantially as described.

7. In a seeding-machine, the combination of the seed-tube B, the elevated main and auxiliary drag-bars, the hangers D depending from the drag-bars, a disk E journaled in said hangers, a furrow-opener I and supporting-arms K attached to the seed-tube, the covering-Wheel K' journaled' in said arms, and a spring-controlling device attached to said drag-bars in front of the disk and furrowopener, substantially as described. 4

In testimony whereof I have hereunto set my hand.
