SPECIFICATION forming part of Letters Patent No. 513,060, dated January 16, 1894.

Application filed May 22,1893. Serial No. 475,184. on. model.)

To all whom it may concern.-

Be it known that we, ANDREW Sonorr and JULIUS LIEsE, both of Belleville, in the county of St. Clair and State of Illinois, have invented a certain new and useful Improvement in Grain-Drills, of which the following is a full, clear, and exact description.

The subject of ourinvention isagrain'drill, constructed with a runner frame and wheel frame jointed together, and in which each shoe is held down to its work independently, by a spring in such a manner that the principal part of the weight of the drill frame is exerted upon the said springs in holding the shoe runners in the ground, and in forcing them into the ground when the machine is thrown into working position by the action of the hand lever. The shoes are lifted by means of rods pivoted thereto and sliding through plates on the drill-frame against which the springs have their bearing, so as to permit the independent rising and falling of the shoes in passing over obstructions. The lifting rods, together with the pressure springs through which they pass are stayed or supported intermediately of their ends by checks or lugs projecting forward from the shoes near the upper part. The pivot connection between the lifting rod and the shoe consists of a wooden pin, which is preferable to a screw or rivet, because it requires no projecting head or nut, as is the case with a screw bolt, and admits of being punched out, when occasion requires, for separating the parts, without cutting or drilling, as is necessary with a rivet. The rear member or wheel frame is connected with a clutch device, throwing the feed mechanism out of gear automatically when the shoes are lifted out of the ground, and springs are employed to automatically throw the feed into gear when the shoes are lowered.

The improvements also embrace other details hereinafter particularly referred to.

In the accompanying drawings, forming part of this specification:-Figure I is a vertical section of a drill, illustrating the invention on the broken line I-I, F-ig. II, showing the parts in working position. Fig. .1 is a detail, sectional elevation of the same parts,

showing the jointed connection between the runner frame and the wheel frame, when the shoes are raised out of the ground. Fig. II is a plan view of the drill, with part of the hopper removed to expose the automaticfeed detaching device. Fig. III is a detail, plan on a larger scale of the automatic feed detaching device. Fig. IV is a rear elevation of the same. Fig. V is a longitudinal section thereof. Fig. VI is a detail, longitudinal section of the dropper, feed tube, shoe, and their accessories. Fig. VII is a front elevation of the same parts, showing the runners in section. Fig. VIII is a horizontal section on the line V IIIVIII, Fig. VI.

1 represents the tongue of the implement, permanently bolted in the customary manner to the runner frame 2, on which the hopper 3 is mounted. The several bars at of the rear or wheel frame are jointed as at5 to the main frame 2, permitting the frames to tilt relatively in a vertical plane, as illustrated in Fig. I, for the purpose of raising and lowering the shoes as hereinafter described. The said wheel frame 4 is supported by an axle 6, and roller wheels 7, following the drill shoes. The shoe runners 8 are connected by draft bars 9 to the main frame 2, by means of pivots l0, permitting them to rise and fall, and on the rear ends of the runners are mounted the. drill shoes 11. The shoes are held down to their work independently by springs 12, supported by internal guide rods 13, which are connected to forwardly tapering ears 11 on the front of the shoes by wooden pins 14, as shown more clearly in Figs. VI and VIII, the ends of the said pins being finished fiush with the face of the ears 11, as shown in Fig. VIII, so as to offer no obstruction or projection.

On the front face of each shoe ll,'near the top, is formed a pair of projecting lugs or cheeks 15, between which the springs 12, and their guide rods 13 are stayed laterally. The springs 12 bear upward against plates 16, bolted to the rear part of the main frame 2, as shown in Figs. I and VI, through which plates the guide rods 13 pass, and move freely up and down, as the shoes rise and fall'independently in passing over obstructions. In

the upper ends of said guide rods are pins 17 which engage with the plates 16 in lifting the shoes bodily from the ground.

To the bottom of the hopper are secured the customary feed boxes or cups 18, in which revolve the ribbed feed disks 19, carried by the shaft 20, and delivering theseed into the spouts 21 from which the flexible feed tubes 22 deliver it within the shoes 11, in the usual way.

The drivers seat 23 is mounted upon bars 24, secured at their front ends by bolts 25 to the tongue or runner frame and supported at the back by standards 26 from the rear of the I wheelframe 4. The oblique bars 24, and supporting standards 26, will thus be seen to constitute a seat-frame supported in front upon the mainframe 2, and at back upon the wheel frame 4.

For the purpose of tilting the connected frames 2 and 4 to the position illustrated in Fig. I, in (irder to raise the shoes above the ground, we employ a bell crank or triangular frame 27, fulcrumed at 28 to the rear of the main frame 2, and connected by pivots29 and hangers 30 to the seat bars 24, to which the said hangersare bolted at 31.

"32 represents a hand-lever mortised into 'the'sideof the bell-crank frame 27, and securely bolted thereto, so as to form a rigid part of the same, so thatthey move together about the fulcrum points 28, 29.

'33 represents the customary segment, provided with notches 34, 35, 36, and 37 to receive a latch 38, operated by a rod 38, and finger-lever 39, fulcrumed to the hand lever 32, for the purposeof securing the hand lever 32 in "any position to which it may be adjusted. It will be understood that by releas ing the hand lever 32, and drawing it'back to the vertical position shown in dotted lines in Fig. I, the bell-crank frame 27, being thus turned onits supportingfulcrum 29, will raise 'the pivot point 28 by which it is connected to therear of the main frame 2, thus tilting the connected frames as illustrated in Fig I, and

through the medium of the suspension plates 7 16, and rods 13, lifting the whole rank of -shoes bodily from the ground tothe position 'shewn by dotted lines in Fig. I, in which po-- sition the'yare held by the engagement of the 1 latch 38, with the rear notch 37. lhe shoes may thus be supported clear of the ground when the implement is to be moved from place to place, without seeding.

The raising of the shoes by the relative tilting of the frames 2, 4, as above described, operates to automatically throw the feed mechanism out of gear by means of the devices which will now be described. The'roration of the feed shaft 20 is eifectedthrough the medium of a sprocket wheel 40, upon a clutch sleeve 41, having the customary ratchet connection with one or more of the Wheels 7, as shown in Fig. II, so as to drive the dropping mechanism, when the machine is going forward, but admit of backing without transmitting movement thereto. The driving chain 42 passes arounda sprocket wheel 43, mounted loosely on the feeder shaft 20, and placed in rotative connection therewith, by a sliding clutch sleeve 44 turning with said shaft, and movedlongitudinally thereon by a bifurcated slide 45, engaging in an annular groove or gland 46 in the clutch sleeve, and actuated by a bell crank lever 47 fulcrumed at 48, en-

. gaging by a pin 49 at one end with a slot in the slide 45, as shown in Fig. III, and drawn forward at the other end by a spring 50, so as to hold the clutch 41 in gear with the sprocket wheel 43.

To automatically stop the feed when the shoes are raised, an arm or standard 51 is mounted rigidly on one of the bars 4, near the joint 5, so thatthe-tilt'ing of the frame in rais* ing thesho'es will impart abackward,11ori- 'zontal movement to the top of saidstand'ard 51, causing a pin52 thereon to'retract'the free end of the bell crank 47againstthe tension of the spring 50, and thus retract th'e'clu'tch 41. This movement is clearly illustrated in Figs. III, IVan'd V. The latch 38 of the hand lever 32 is then caughtin the notch 37 of the segment 33. To lower the shees 11 to wet-l0 and hold them at the desired depth'of penetration.

The combination of the tilting orrunner frame 2, independently pivoted shoes l'l having'cheek plates 15 near their upper ends, lifting rods 13 pivoted to the shoes, and sliding through plates 16 on the frame and springs 12bearing at bottom against shoulders on'the shoes and at top against the plates -16;substantially asand for the purpose set'forth.
