ARTHUR F BROIVN, OF DAYTON, OHIO, ASSIGNOR TO THE STODDARD MANUFACTURING COMPANY, OF SAME PLACE.

COMBINED SEEDER AND HARROW.

- SPECIFICATION forming part of Letters Patent No. 408,290, dated August 6, 1889..

Application filed November 2, 1888. Serial No. 289,794. (No model.) I

To all whom it may concern.-

Be it known that I, ARTHUR F. BROWN, a citizen of the United States, residing at Day ton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Combined Harrows and Seeders, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a harrow of that class known as rotary disk harrows, upon which is mounted a seed-box whose feeding mechanism is operated from one or both of the dislegangs; and it has for its object the improvement in the construction and mode of operation of such machines.

The novelty of my invention will be herein set forth, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1, Sheet 1, is a plan view of a harrow embodying my invention, but with the seed-box removed. Fig. 2, Sheet 2, is a side elevation of the machine. Fig. 3, Sheet 2, is a rear elevation of the machine. Figs. 4, 5, 6, and 7, Sheet 3, are enlarged details, to be referred to more particularly hereinafter. Figs. 8, 9, and 10, Sheet 4:, are likewise enlarged details, to be referred to more particularly hereinafter.

The same letters are used to indicate identical parts in all the figures. Y

The frame of the machine is composed of the following parts: The tubular metal crossbar A, to each end of which is secured a downwardly-curved and tapering casting B,

whose upper end, embracing the bar A, is slotted on each side, as at a, Fig. 4, and provided with ears I) to receive clampingbolts c, and whose lower end is provided with a vertical spindle d, the central forwardlyprojecting metal L-bars C, Figs. 1, 8, and 9, bolted to the bar A at theirrearends and connected at their forward ends by the cross-bar 1), Figs. 2, S, and 9, riveted to the bars 0, the drivers scat-beam E, secured to a cross-bar F, attached to the bars 0, and the brace-rods G, Figs. 1 and 2, extending from an arch-bar 11 upon the bars 0 back and outwardly .to

thimbles J, between the second and thirdouter disks, enlarged and provided with rearwardly-projecting vertically-perforated lugs f, in which the spindles d are inserted and secured with keys thus forming hinges 011 which the gangs can be angled as desired, and with'sufficient play in the joint to permit the gangs to vibrate vertically and independently for a limited distance, to follow the inequalities of the ground.

In Fig. 1 I have shown a three-horse hitch with a well-known form of draft-equalizer, of which the doubletree K is pivoted to a slide L, confined between the bars C, and Whose slotted sides embrace the horizontal portions of said bars. To a strap M, Figs. 8 and 9, connecting the slide L to the under side of the doubletree-bolt, is secured a pendent casting N, having two vertical perforations 71, through which are inserted the forward perforated ends of two draw-bars O,one for each of the disk-gan gs, and each of which extends back and has its rear end bent downward, (see Figs. 1 and 6,) and has its spindleshaped end inserted through a perforation in a lug t' upon the forward side of the thimble P between the two inner disks of each gang, and has its elbow united by ahook j to a strapbar 76, secured to and extending up from said thimble, thereby forming a secure and what I designate a compensating hinge-joint. Pins Z are inserted through the perforations in the forward ends of the draw-bars and bear against the forward side of the casting N.

To hold the slide L locked from forward movement and to adjust it backward or forward to determine the position of angling of gangs by the power of the team and the re sistance of the earth, I employ the lock-lever Q, pivoted, as at m, and provided with a pivoted dog a, engaging with a segment-rack 0 upon the bars C, and united to the slide L by the pivoted link R. The lever Q may have an upper removable extension S, with the usual latch mechanism for lifting the dog a; or the dog n may. have a rear extension T, Figs. 2, 3, and S, by which the dog and slide can be operated from the rear of the seedbox, as will be readily understood. To prevent the gangs from rising too far at their inner ends, I provide stops U, Figs. 1 and 8, which project down from the bars C over the upper edges of draw-bars O.

The scrapers V for each gang are pivoted to arms 19, strung and adjustably held by means of set-screws q upon a bar W, preferably square in cross-section, and adj ustably held in a perforated head projecting from and secured to the bar K, and another head 3 upon a bar 6, secured to and extending up from the lug f. Thus it will be seen that the scrapers can be individually adjusted to or from the disks and can also be adjusted in a body by sliding the bars W.

The seed box or hopper y, of the usual or any suitable construction, is supported upon and removably connected to the frame by means of the two rear strap-bars 20, which extend down from the rear side of the hopper and are secured by screws or bolts to lugs '0 upon the castings B, and by the two convergent strap-bars 20, which extend forward from the hopper and are screwed or bolted to the bars C.

Upon the convex side of the inner disk of one of the gangs is a sprocket-wheel A, Figs.

' 1, 3, 6, and 7, from which a chain B extends up to a sprocket-wheel 0, having a clutchhub to, and loose upon a spindle D, j ournaled in a box or sleeve E, secured to an upper extension of the bar 70. Feathered upon the spindle D, by side of the hub a, is a second clutch-hub Z), Fig. 10, having an annular recess c and a slot for the feather or pin (1, secured to the spindle. A spring 0, surrounding the spindle between a collar or nut f upon its end and the clutch I), normally holds the latter in engagement with the clutch a, so that the revolution of the sprocket O is transferred to the spindleD, as will be readily understood. To stop the revolution of the spindle at any time, it is only necessary to draw back the clutch 1) until it is disengaged from the clutch a and the pin (1 is out of its slot, whereupon by turning the clutch b slightly the pin (1 is caught against the wall of the recess 0 and the clutch locked out of engagement.

The revolution of the spindle D is communicated to the feed-shaft F of the hopper by means of a rod G, Figs. 2, 3, and 7, united by gimbals H to the spindle D at its lower end and to a short spindle I, journaled in boxes secured to the rear side of the hopper and carrying a pinion g, meshing with a pinion h upon the shaft F. The rod G, preferably square in section, is free to slide in its socket in one of the gimbal-sections to enable it to accommodate itself to the movements of the gang.

The seed cups and spout-s of the hopper are of the usual or any suitable construction,and while I have shown the machine with thills secured to a cross-bar T upon the bar D, it is evident that a pole may be employed as well where a two or a four horse hitch is desired.

Having thus fully described my invention, I claim- 1. The cross-bar A, composed of tubular metal and having secured upon its ends the curved tubular castings B, provided with the slots a and clamping-bolts c, in combination with the main frame and the disk gangs hinged to the vertical spindles of the castings B, substantially as and forthe purpose specified.

2. The main frame composed of the tubular cross-bar A, having secured upon its ends the curved tubular castings B, the L-bars C, bolted to the cross-bar A and united at their forward ends by the bar D, and the bracerods G, extending from the forward ends of the bars 0 to the castings B, in combination with the disk-gangs hinged to the castings B,

substantially in the manner and for the purpose specified.

3. The combination,with the sliding doubletree and its slide L, of the casting N, having vertical slots 71, the draw-bars 0, having their forward ends inserted through and confined in said slots and their rear ends bent down and hinged to the inner ends of the diskgangs, the hooksj, uniting the elbows of the draw -bars to upward extensions from the gang-axles, the main frame, and the disk-gan gs hinged thereto, substantially as described.
