DISK DRILL.

SPECIFICATION forming part of Letters Patent No. 768,7 63, dated August 30, 1904.

Application led May 2, 1903. Serial No. 155,328. (No model.)

To all whom, it 71mg concern:

Be it known that I, VILLIAM A. LEE, a resident of Blackwell, in the county of Kay, Oklahoma Territory, have invented certain new and useful Improvements in Disk Drills; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in disk drills, the object of the invention being to so construct a disk drill that it will be simple in construction and have as many parts as possible integral or rigidly secured together,`

each part having a distinct and useful application for its special work in connection with the whole of the drill construction and at the same time be strong and of proper weight, shape, and size to perform the best results and cheapen the cost of manufacture.

A further object is to so construct a tongueframe and hounds in connection with the drillframe and said tongue and hounds joined together in such manner that they will be sufiiciently strong to carry the disks and frame of said drill and at all times sustain the lateral and vertical strain of the drill in operation and provide improved operating mechanism so connected with the rear of this tongue-frame and hounds as will permit the operator to raise and lower the disks and feed-tube at will.

A further object is to provide improved furrow-opening and furrow-closing or seedcovering disks and so connect them with the seed-dropping tubes, which are pivotally supported, that they are compelled to always remain in proper relative position for perfect planting regardless of the vibrations or adjustments of the disks and allow all of said parts to vibrate to pass obstructions or un,- evenness in the ground.

A further object is to so construct adisk drill that the disk furrow-openers shall operate under the front cross-bar of the drill-frame and that the disk furrow-openers shall act similarly to that of the foot of a plow-stockysoV that the weight of the frame and parts carried thereby will hold the disks to their work as the drill is drawn over the ground.

With these objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in -side elevation illustrating my improvements. Eig. 2 is a top plan view. Fig.

3 is an enlarged view in section showing details of the disk-mounting and associated parts. Fig. 4. is a top plan view of the disk journalbox, showing arms 16 secured thereto. Fig. 5 is a View in longitudinal section illustrating the disk journal-bearing. Fig. 6 is an enlarged perspective view of the bracket l2, and Fig. 7 illustrates the coperating parts of the disk journal-bearing separated.

My improved drill-frame comprises an angle-bar 2, on which the seedbox 3 is mounted, and to thisy angle-bar 2 a forwardly and downwardly projecting yoke 4 is secured and comprises a cross-pipe 5, connected at its ends by pipe-'couplings 6 with side pipes 7, secured to the angle-bar 2 by means of suitable collars and set-screws. Suitable stanchions 8 connect the axle 9 with angle-bar 2, and a sec ries of presser or traction wheels 10 are mounted to turn on this axle9.

rl1 represents the seed-dropping tubes, which are connected with the cross-pipe 5 by means Vof brackets 12. These brackets 12, as shown cured in place by nuts 13C. have integral webs 15 between the arms 13, and parallel compound curved bars 16 are secured to the opposite sides of these webs l5 by bolts q15", passed through the bars and webs. vThe forward ends of these bars 16 are secured on opposite sides of an upright web 17 on a plate or casting 18, which latter is secured upon fiat rearward extensions 19 on .9o the seed-tubes and through the arms and se- These brackets 12 point about midway its ends.

journal bearing boxes 2O and is secured thereon by bolts 21, passed through elongated slots 22 in the plates, and extensions which permit the position of the journal-boxes to be adjusted at will. These journal-boxes 2O have sand-bands 23 at both ends and are adapted to receive hollow journals 24, which project beyond the boxes and are externalljT and internally yscrew-threaded at both ends. Collars 25 are secured on the ends of each journal 24 and made with annular grooves to receive the sand-bands and exclude all dirt and grit from the bearing. The furrow-opening disks A are located on the journals against collars 25, and headed screws 26 are screwed into the ends of the journals, closing them and effectually clamping the disks between the heads of the screws and the collars 25. Openings 24lL are provided in the journals 24 and journal-boxes 20, through which lubricant can be supplied to the journal and fed to the bearing, and, if desired, these journals can be filled with waste to more eifectually hold and feed the lubricant, or I might extend the journals out beyond the disks and screw cap-nuts thereon.

rIhe downwardly-bent rear ends of the several pairs of bars 16 are connected by bolts and receive between them bars 27, secured to the frame-stanchions 8, and coiled springs 28 are located on these bars 27 and bear against an enlargement or pin at their forward ends and at their rear ends against the bars 16 to yicldingly hold the disks in the ground or working position, but permit them to elevate in passing obstructions or permit themthe desired fiexibility in ordinary use to perform the best results. Each seed-tube 11 has a bearing 29 on its rear edge, in which a standard 30 is adjustably secured by a set-screw 31, and this standard has at its lower end a bearing for a covering-disk B. These covering-disks B have rotary mounting and are preferably smaller than the main disks A, and their angle and depth can be varied by adjusting the standard 30 in bearing 29 and securing at such adjustment by the set-screw.

The tongue-frame comprises a bar 33, extending through the center of main frame. Side bars or hounds 31 are located on opposite sides of bar 33 and extend forward parallel therewith for a short distance and then converge and are secured to main bar 33, and inclined bars 32 connect the converging portions of bars 31- with the central bar 33 at a In the forward end of this bar 33 a fork 35 has rotary mounting, and caster-wheels 34 aremounted at the lower ends of this fork 35 to support the forward end of the frame, and a suitable clevis or coupling' 36 is provided on fork 35 for the attachment of a doubletree or pole to which the draft animals are hitched.

On the cross-pipe 5 sleeves 37 are secured and have parallel lugs 38, between which rearwardly and upwardly extending bars 39 are secured and pass through clips 40 on anglebar 2, and one of these bars 39 is bent over to the other, and a block 41 is secured between them, to which block the seatsuj'iporting spring 42 is secured and carries the seat 43". On this bent bar 39 a toothed segment 43 is secured, and an L-shaped lever 44 is pivotally secured against said segment and has a springpressed detent 45 to lock the lever in any position.

The rear ends of the hounds 31 are connected by an arched bar 46, and the latter is connected with the bar 33 and hounds by braces 47, and a link 48 connects the brace 47 on bar with the end of lever 44, so that when said lever is moved the hounds 31 and bar 33, which I term the tongue-frame, will be moved up or -down to depress the disks and feed-tubes or elevate them, as the case may be.

A shaft 49 turns in bearings carried by crossbar 2 and operates the seed-droppers, which deposit the seed in wire tubes 50, projecting into the flared upper ends of the seed-tubes 1l, and sprocket-wheels are located on this shaft 49 and on the axle, and a short shaft 5l carries a fixed sprocket-wheel 52, which is connected by a chain. 53 with the sprocket on the axle. A sprocket-Wheel 54 is mounted to slide on the shaft 51, and suitable means are provided to moven the same to clutch with the sprocket 52 and lock them together, and a chain 55 connects this sprocket 54 with the sprocket on shaft 49, so that when the sprockets 54 and 52 are clutched together motion will be transmitted to the shaft 49 to operate the seed-droppers, and when the sprocketwheel 54 is moved away from sprocket-wheel 52 the seed-droppers will be idle.

It will be. seen that with my improvements the disks A are pushed forward and not dragged, as heretofore, that the seed-tubes 11 carry both the main and covering disks and maintain them in proper relative position te perform the best results, and as the seed-tubes pivot on the cross-pipe 5 vertical vibration of the disks is allowed.

A great many changes might be made in the general form and arrangement of the parts described without departing from my invention, and hence I do not confine myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.
