GRAIN-DRILL.

Specification of Letters Patent.

Patented Nov. 17, 1908.

Application led June 27, 1907. Serial No. 381,084.

To all whom it may concern:

Be it known that I, DUNY A. SCHUTT, a citizen of the United States, residing at Peru, in the county of Miami and State of Indiana, have invented certain new and useful Improvements in Grain-Drills, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention refers to improvements in grain drills for the purpose of planting grain or seed and it has for its object to provide an apparatus of this class which will properly distribute the grain or fertilizer or both; to provide simple and' efficient means for driving the mechanism from one or both of l the supporting` traction wheels, depending` on the direction of travel; means for simuli taneously lifting the feeding disks and for l I l l l l l l l throwing the eeding mechanism out of gear; means for raising and lowering the frame with relation to the supporting wheels g means `for providing resilient mounting for i t-he disks and hangers; means for flexibly connecting the tongue and draft gear, and various other features of improvement as shall be more fully hereinafter described.

The present invention embodies improveil ments in that class of mechanism set forth in my copending application filed Dec. 6th, 1906, bearing the Serial Number 346663.

Referring to the drawings -Figure 1 is a plan view of the complete machine. Fig. 2 is a rear elevation, portions of the meehanism being shown in section, the back frame seat, etc., having been removed. Fig. 3 is an enlarged end elevation, showing the frame of the machine in its lowermost position and indicating the working position of the disks. Fig. 4t is a vertical sectional detail view on the line IV. IV. of Fig. 3. Fig. 5 is a transverse vertical section on the line V. V. of Fig. 1, showing the frame lowered with relation to the supporting axle, the disks being raised. Fig. 6 is a similar detail view, showing the frame raised with resectional view on the -line VII. VII. of Fig. 6. Fig. 8 is a transverse vertical sec tional view through the middle of the machine on the line VIII. VIII. of Fig. 1. Fig. 9 is an enlarged horizontal sectional view indicated by the line IX. IX. of Fig. 3. Figi() is a vertical detail sectional view indicated by the line X. X. of Fig. 8. Figs. 11 and 12 are detail views on an enlarged l scale showing a modified construction or mounting of the disk hangers. Fig. 13 is a. detailed view of one of the lifting levers, not slotted.

The main frame of the machine consists of front and

back bars

2, 3 and an intermediate transverse bar 1l, bars 2 and d being secured at the front and bar 3 being secured at the back, at both sides of the machine, to oppositely disposed flanges 5, 5, of the housing boxes 6.

7 is the main supporting axle of the machine, mounted at each side in the axle boxes S, said axle having mounted upon it at each end, by hubs f), the supporting traction wheels 10 of usual construction. The wheels 10 are provided at the inner ends of their hubs with ratchet driving mechanism for imparting movement on forward travel of the machine to the feeding mechanism, as hereinafter described.

Housing boxes 6, with which the

bars

2, 3 and L1; are connected, support thev entire framework of the machine and its superimposed and depending mechanism, said housings and framework being arranged for veri; tical adjustment with relation to the axle bearings, to any degree desired and are thus capable of adjustment with relation to the surface of the ground.

11 and 12 represent the grain and gra-in boxes respectively, which are mounted transversely of the machine upon suitable end plates or frames 13 supported by legs 111 upwardly from the inner sides of forward iianges 5 of the housings 6, or in any other suitable manner. The grain and fertilizer, or either, are fed by feeding mechanism actuated by

shafts

15, 16 respectively, said shafts being preferably separated at their middle portions, and each section with its feed wheels driven by the gearing at each outer end.

"he fertilizer feed shafts 16, which may conveniently be square or splined, are pr0- vided at their ends with longitudinally movable or sliding bevel gears 17 normally held in mesh with driving bevel gears 17 by spring 1S and arranged to be depressed backwardly to throw them out of gear by a sleeve 19. Sleeve 19 is mounted on the outer end of shaft 16 by a reduced extension Q0 extending through end plate 21, forming a part of or secured to the lower portion of the grain and fertilizer box plate 13. Sleeve 19 is preferably beveled or coniform as at 9.2,

providing a bearing for the fork-shaped unshipping wedge 23 mounted transversely across the inner side of plate 21. The wedge 23 is actuated by lever 24 pivoted at 25 and having a depending' crank extension 26. Likewise grain feed shaft 15 is adapted to be thrown out of gear by means of a doo' 27 mounted on shaft 28 provided with a crank arm 29, said. dog 27 being arranged to bear upwardly underneath shaft 30 of the driving gear 31 employed to transmit motion to the said grain feed shaft 15, thus throwing gear 31 out of mesh with gear 17. Shaft 30 and gear 31 are normally7 pressed downwardly into operative position by spring c bearing' against shaft 30 and a fixed abut-V ment, it being understood that shaft 30 is mounted in slotted bearings.

Motion is imparted to bevel gear 17 and to bevel gear 31 (on shaft 30) simultaneously by driving bevel 17 when said gears' 17 and 31 are in mesh therewith. Driving bevel 17 is mounted at the upper end of the square or splined shaft 32 with which slidingly engages the hub 33 of bevel gear 34 in mesh with driving bevel 35. Said bevel 35 is loosely j ourn aled on the axle 7 and is provided at the outer end of its hub with a series of ratchet teeth 36 adapted to be engaged, on forward motion of the machine, by pawls 3G of the wheel hubs, more clearly shown in F ig. G.

The wheels 10 are j ournaled by their hubs on the outer ends of the stationary axle 7, being free to rotate in either direction, but by the pawl and ratchet teeth construction which have just described, will only impart feeding motion to the gearing' and the grain and fertilizer feed mechanism when running' in a forward direction.

The axle 7 is mounted at each side of the machine in axle boxes S as stated, and the outer portion of each axle box is closed by a removable cap 37 whereby the various parts may be taken apart. The axle box 8 is, as shown, made of considerable length to embrace the axle and is provided with an extension 38 upon which rests a projecting button or knob 39 of gear whereby said gear is normally maintained in mesh with driving gear 35. lts hub 33 extends upwardly through the upper bearing portion 40 of the housing 6, having a sliding bearing therein, and said hub is lengthened as shown and embraces the square shaft 32 by a corresponding squared central socket 41, sufficient space being left between the top of bearing 40 and the lower side of the hub of driving gear 17 to permit of the necessary vertical play. By this construction it will be seen that the frame of the machine and housing 6 may be vertically adjusted with relation to the axle boxes 8, while still maintaining driving transmission between gear 35 and gear 17 at each side. For the purpose of effecting said vertical adjustment I employ a lever 42 pivoted at 43 to the inner side of housing 6, and at 44 the terminal of lever 42 is slotted and engages a stud fixed to the lower side of axle box S, the other end of lever 42 being pivoted at 45 to a link 4G which in turn is pivoted at 47 to crank arm 43 mounted on shaft 49. Saidy shaft is preferably squared, extending' transversely of the machine at the back through suitable thimble bearings in brackets 50, and is actuated by the operator through a lever 51. Said lever is connected by a link 52 with a crank 53 mounted on the lower end of vertical spindle 54 mounted in suitable bearings 55 and provided with an operating handle lever 56.

57 is a ratchet wheel, locked by a footoperated spring-pressed pawl 53, whereby the position of lever 51 and the relative positions of the axle box and housings are maintained. It will be understood that such construction is used at both sides of the machine, and that upon operating' spindle 54, the connections 44 acting as fulcrums, the entire frame of the machine may be raised and lowered by reason of its being supported by pivotal connections 43. By this means the adjustment of the machine towards or from the ground level may be accurately regulated.

Referring again to the means for driving the grain and fertilizer feed mechanism, the fertilizer feed mechanism being already apparent, driven gear 31 imparts power through shaft 30 and bevel gear a to bevel gear Zi on shaft 15, when the gears are all in mesh. In order to throw out both the grain and fertilizer feed from the machine the levers 26 and 29 are actuated simultaneously,l or one or the other may be actuated alone by disconnecting the other, by means of connecting rod or link 59 pivotally attached at its other end G0 to the crank arm 61 mounted on spindle 62 having an operating lever or handle G3 at its upper end. Said spindle 62 is, like spindle 54, mounted in bearing 64 at the back of the machine and is also provided with a ratchet wheel 57 and foot-actuated pawl 58, whereby its position may be fixed at all times.

Spindle G2 is designed to perform the double function of throwing out the grain and fertilizer feeds and of simultaneously lifting the feeding' disks of the apparatus, and on the other hand of simultaneously throwing in the grain and fertilizer feeds and lowering the disks, so that feeding of the grain or fertilizer, or both, can only be supplied to the disks when they are in position for operation in the ground.

65 are the feeding' disks j ournaled for rotation upon the hub of the disk hanger (36 carried at the rear end of drag bar 67 and provided with upwardly extending conduits 68 to which grain or fertilizer, or both, are

supplied by means of flexible tubes 69 from the feeding mechanism, in the well known manner. The drag bars 67 are pivotally mounted at 70 upon a suitable pivotal bearing shaft or support depending below the front portion of the machine, and all the drag bars, disk hangers, and disks are designed to be raised and lowered simultaneously by the operator. For such purpose 1 provide a rock shaft 71, preferably squared, extending transversely across the machine at its front upper portion, mounted in suitable bearings and provided with a series of downwardly extending levers 72. Said levers are preferably slotted as at 7 3, and connected at their outer ends with connecting rods 7 4 which in turn are pivotally connected at with the disk hangers.

76 are a series of pins or rods pivotally connected at 77 with the drag bars 67 and having surrounding pressure springs 78 bearing upwardly against blocks 79 having a sliding engagement with slots 78 by pins SO. By this `construction it will be seen that there is at all times provided a resilient cushioning downwardlypressed bearing against the upper side of the drag bars, tending` to positively insert the disks downwardly into the earth all at the same time, with means for lifting the disk hangers and disks against the said resilient pressure. Levers 72 are also provided with limiting arms 81 adapted to bear upon the upper edge of the bar 4t when the disks are lowered, as shown in Fig. 3, and to be lifted upwardly therefrom when the disks are raised as in Fig. By means of such arms S1 it will be seen th'at the entire strain is taken off of the lifting mechanism and the disks are positively supported in position for operation,

Levers 72 and all of the disks are actuated upon rotation of rock shaft 71. To accomplish this I employ a lever arm 82 pivotally connected at S3 with arm Sel, which arm in turn is connected at its rear end with crank 85 on the lower end of spindle 62 and capable of operation like crank The connecting ends of lever S2 and rod Set are of elbow form whereby to facilitate the operation and provide suflicient clearance for the other parts of the mechanism.

By the construction above described it will be. seen that the grain and fertilizer' feeds and the raising and lowering of the disks, are controlled from the single spindle 62. Said spindle and spindle 54 are, as shown in Fig. 1, located at one side and the other re spectively of the drivers seat S6, so as toV be within easy reach of the operator.

87 is a curved bar or bars extending upwardly and backwardly from the main cross bar 4, connected by brace S8 with back bar 3, and supporting the drivers seat, said bar 87 having at its forward lower portion up- 'wardl'y and inwardly projecting cheeks 89.

90 represents the tongue of the machine supported by bracket arms 91 upwardly above the front bar 2 and pivotally supported at 92 upon a transverse bolt connecting the flanges of brackets 91. At its rear end tongue 90 is provided with a strap 93 surrounding a bolt 91 extending across from one cheek 89 to the other, and by this construction it will be seen that considerable vertical play is provided within strap 98 whereby the forward end of the tongue may be raised or lowered to a considerable extent. This is a feature of great advantage in adjusting the tongue to the horses and renders the work of drawing the machine easy.

95 is the double-tree, not mounted on the tongue as is ordinarily the case, but directly attached to the main frame. The tree 95 is pivotally mounted by king bolt 95 within the upper and lower sides of a clevis 96 verw tically pivoted at 97 in block 98 secured by bolt 99 between an upper plate 100 secured to bar 2 and a lower bar 101 extending forwardly from underneath the main bar 4L. By this construction it will be seen that the power of the draft horses is imparted directly to the main body portion of the machine, a feature of advantage contributing to the durability, tiexibility and ease of operation In Figs 11 and 12 I have shown a modified construction whereby the raising and lowering of the disk hangers and disks and also the maintaining of the resilient cushion ing pressure is secured by a single mechanism. Upon rock shaft 71 are mounted the levers 72 provided with a slot 73 and the integral supporting extensions 81 adapted to bear upon the main bar 4. Said bar et is located somewhat forwardly in the machine and the mechanism is arranged in reverse of that already designed, it being understood that the rock shaft 71l is however actuated by the same lever Connection. Rod 76 is pivotally mounted at 102 between cheeks 103 cast integral with the disk hanger, rod 76 being similarly surrounded by Vcoil spring 7 8 bearing downwardly against the washer disk 104 secured by Cotter pin or otherwise to rod 76. At its upper end rod 7 5 passes through and has a sliding bearing in block 105 of stem 106 which passes through slot 7 Spindle 76 extends upwardly through and beyond the block 104 and is provided with a limiting nut 107 so located as to bear down on top of block 105, when the disk hanger is lifted, as in Fig. 12, but which may be pushed upwardly above said block more or less owing to the operation on uneven ground. The upper end of stem 76 is threaded for a considerable distance whereby the nut may be set to any desired position to adjust the mechanism to suit the ground etc. An advantage in the slotted construction of lever 72 is that the stem 106 of the lifting block 105 may, if necessary, slide into the slot, providing ample clearance and freedom of motion while greatly facilitating the lifting operation. Thus assulning the stem 107 to have slipped from one end tothe other of the slot, when the lever is operated pin 106 will slide along in the slot while the wedge-like action of the lever as it is lifted will greatly ease the operation. By this construction, I also avoid the necessity of the supplemental connecting rod 74 and secure the raising of the disk by the same means, through which the downward cushioning pressure is exerted. In Fig. 13 I also show a modified construction of lifting lever wherein the slot is eliminated, the connecting rod being' pivoted to the lever as at 108, and good results may be had with this arrangement, the construction otherwise being the same as already described.

The various advantages and improvements of my invention will be fully appreciated by all those familiar with this class of apparatus. The machine is unde1 the complete control of the operator; it provides against waste of grain or fertilizer; gives a construction capable of an accurate degree of adjustment to suit all conditions of ground level, providing a well balanced machine, reducing the work of the horses to a minimum, and simplifying the construction in many essential respects. The size, details, design, or other features of the invention may be varied or changed by the skilled mechanic, and I do not desire 'to be limited to the exact construction shown, as many of these elements may be altered to suit varying conditions.
