.To @ZZ whom it may concern:

Beit known that I, WILLIAM J. DEALTRY, a citizen of the United States, residing at Louisville, in the county of Jefferson and object to provide a novel arrangement and construction of metal frame for this class of agricultural implements, and has particular relation to the employment of a single metal center piece which acts as a support for the connecting parts and to brace and strengthen the frame. Heretofore such center pieces have been Aconstructed of several pieces of wood, with the various metal parts bolted thereto, and with this construction the wood is -liable to warp and the joints work loose, and to obtain sufficient strength the center pieces must necessarily be made heavy and cumbersome. It is to overcome this defect and to combine lightness with strength and durability that this part of my invention is directed.

A second part of novelty consists in the particular construction of sprocket-wheel and hanger on the feed-shaft under the feed-box, whereby the least possible space is occupied between the feedand the adjacent hopper end. It is frequently'desired, in certain sections of the country where the land is rich and especially adapted to the raising of grain, to sow the seed in narrow rows of tive or six inches apart. In seeding implements as heretofore constructed, where the feed-cups are thus located close together, the ordinary construction of hanger and sprocket-wheel for driving the feed-shaft cannot be used, because the space taken up by these parts is too great, and consequently it has been customary to drive the vfeed-shaft in suchma- .sprocket-Wheel method of driving the feedshaft by means of a novel construction and arrangement of hanger and sprocket-wheeldesigned to occupy very little space.

The third part of Iny invention consists in a novel, simple, and cheap method for automatically throwing the feed into and out of gear simultaneously with the raising of the drills of the seeding-machine.

In the drawings, Figure 1 'is a plan view of the seeder-frame, with axle and shiftingclutch mechanism. Fig. 2 is a side view of same. Fig. Sis a side view of the malleableiron center piece. Fig. 4 is 'asectional view of the shifting mechanism. Fig. 5 is a plan view of same, with a portion of the frame broken away. Fig. 6 is a front view of the clutchshifting device. Fig. 7 is a side view of the sprocket and hangers on the feed-shaft under the seed-hopper. Fig. 8 is'a longitudinal section of same.

In the drawings, A is a front portion of the metal frame of the machine, preferably made of angle iron or steel, to which the drag-bars to secure the shoes or hoes are attached.

C C are the ends or sides of thejframe, preferably made of malleable iron and securely bolted to the frame A, and B is a cross-piece' connecting the end pieces, also preferably made of angle iron or steel.

D is a malleable-iron center piece and is used'principally in seeding-machines of large size and acts as a support for the connecting parts. At the point where the cross-piece B intersects the center piece a lip or shoulder D is formed thereon, which shoulder extends over the cross-piece'B, as shown in Fig. 3, and

Vwith the fixed clutch I-l onthe axle.

already stated, I believe this malleable-iron center piece, with its lip projecting over the cross-piece and with the pin cast on the front end thereof, is a novel construction and arrangement, and it takes the place of the older forms of wooden center piece which have heretofore been made in several pieces, which, as has already been stated, are liable to warp and loosen the joints.

E is the hollow rocker-bar extending across the rear of the frame and supported on the end pieces C C and center piece D. To this rocker-bar are attached the arms connecting the same in the usual way with theshoes or hoes, and the bar is rocked back and forth by means of the usual ratchet-lever and arch placed either at the ends or at the center. These parts are not shown in the drawings, as they are of the usual and wellknown construction.

F is the axle for the carrying-wheels of the machine, extending across under the frame and working in the journal-boxes G G, which are supported in the ends or sides of the frame C C. Mounted on this axle, preferably at one end, is the clutch-collar H, secured rigidly thereto by the set-screw H.

I is the combination sprocket-wheel and clutch-collar mounted loosely on the axle, and when the machine is in operation it is held in clutch with the collar Il by the coiled spring l', which is secured in position on the axle by the set-coilar I2.

J is a forked shiftencrank pivoted by means of a stud-bracket to the cross-piece B, the forked end of which engages with a groove in the sprocket clutch-collar I. The other or outer end of this shifter is provided with an opening through which passes the connecting rod K, which is secured to the rocker-bar E by means of the rocker-arm K2. A Cotter-pin K3 is secured to the other end of this connect` ing-rod K, so that when the rocker-bar is rocked backward to raise the shoes or drills the Cotter-pin engages with the end of the shifter, thus turning the same and throwing the sprocket clutch-collar out of engagement Then the rocker-bar E is thrown forward, the connecting-rod slips through the opening' in the end of the shifter and the coiled spring l throws the sprocket-clutch again in connection with the'axle.

A sprocket chain (not shown) connects the sprocket I with a sprocket-Wheel O, mounted on the feed-shaft P and supported in the hangers N N secured to the bottom of the seed-box.

As has already been stated, as ordinarily constructed the feed-shaft sprocket-wheel and hangers therefor take up too much space to allow the seed-cups to he placed closely to gether. To remedy this defect the web of the sprocket-wheel O'is recessed on both sides, as shown in Fig. 8, to a depth corresponding to the thickness of the lower ends of the snpportinghan gers, so that the hangers are flush with the outer edge of the sprocket-hub and occupy no additional spaceon the feed-shaftP.

L L are stay-rods extending the full length of the machine and secured to the outside ends of the frame by nuts, these rods acting as supports and preventing any tendency to sag in the frame, while M is the rear end of the hitch-bar that supports the doubletrees and is fastened to the center piece D.

Having thus described my invention, what I claim, and desire to secure by Letters Iatent, is

l. In a seeding machine, the combination, with a metallic frame therefor, of a metallic center piece having a lip or shoulder formed thereon, and cross piece connecting the frame ends and secured to said center piece under and against said overhanging lip, substantially as shown and described.

2. In a seeding machine, the combination, with a metallic frame therefor, of a metallic center piece having a lip or shoulder formed thereon, and a pin integral therewith at its forward end, with cross piece connecting the frame ends and secured to said conter piece under and against said overhanging lip, and front piece with hole therein for the reception and riveting thereto of said pin, substantially as shown and described.

3. In a seeding machine, the combination, with a sprocket clutch mechanism for communicating lmotion to the seeding devices, of a shifting crank pivoted to the frame in engagement with said clutch mechanism, a

Vrocker bar for elevating the sh oes or hoes of the machine and a rod connecting said rocker bar and shifting crank, whereby upon the elevation of the shoes the sprocket clutch will be disconnected, substantially as shown and described.

4. In a Seeding machine, the combination, with the axle, of a spring controlled sprocket clutch in connection with a rigid clutch on said axle, a shifting `crank pivoted to the frame in engagement with said sprocket clutch, hole in the outer end of said crank with rod sliding therein in one direction, and pin on said rod contacting with said shifter when the rod is shifted in the other direction, rocker bar for elevating and depressing the drill shoes, and rock arm thereon to which said rod is connected, whereby the elevation of the shoes will disconnect said clutch mechanism, substantially as shown and described.

5. In a seeding machine a sprocket wheel for driving the feed shaft with annular recesses in its web on both sides and a hanger for supporting same fitting within said annular recesses so as to be flush with the hub thereof substantially as shown and described.
