To aLZ whom it may concern:

Be it known that LJACOB HENRY ULL- RICK, a citizen of the United 'States, residing at Nashville, in the county of Davidson and State of Tennessee, have invented a new and useful Grain-Drill, of which the following is a specification.

The invention relatesto grain-drills.

The present application is a division of the application filed by me on or about September 14, 1905, Serial No. 287,441.

The object of the present invention is to improve the construction of grain-drills, more especially the means for mounting-and adjusting the drag-bars, and to rovide a machine'of this character adapte to operate effectively both on clean and trashy ground and capableof ready adjustment to arrange the hoes or other drilling devices, such as disks, either in a perfectly straight line for clean ground or in substantially V form for throwing off the trash at the sides of the grain-drill.

The invention also has for its object to pro vide a grain-drill in which the hoes or other drilling devices may be readily adjusted to throw them into and out of operation and to arrange them at the desired depth.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size, and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the in vention.

In the drawings, Figure 1 is a plan view of a grain-drill constructed in accordance with this invention. Fig. 2 is a longitudinal sectional view taken substantially on the line 2 2 of Fig. 1. Fig. 3 is a transverse sectional view taken substantially on the line 3 3 of Fig. 1. Fig. 4 is a detail view illustrating the arrangement of the spring for holding the slidable clutch sections or members in engagement with the clutch members or sections of the carrying-wheels.

Like numerals of reference designate corresponding parts in all of the figures of the drawings.

1 designates the main or. supporting frame, which is of angular form,.being substantially V form in plan view, and provided at opposite sides of the center with transverse bars 2 and 3, arranged at an angle and diverging rearwardly and connected by outer and intermediate longitudinal guide-bars 4 and 5, suitably secured to the transverse bars 2 and 3. The outer bars 4 are extended in rear ofthe bars 5 andrare suitably secured to a transverse shaft or axle 6, which is provided with carrying-wheels 7.

The longitudinal guide-bars 4 and 5, which consist of channel bars or beams, are provided with top and bottom flanges, forming grooves or ways for the ends of slides 11, to which are connected drag bars or beams 12. The guide-bars 5, which are arranged in pairs, are fitted back to back, as clearly shown in Fig. 3 of the drawings; but I bars or beams having opposite flanges may be employed'instead of separate bars-or beams, as will be readily apparent. The slides, which move longitudinally of the machine to'arrange the drill-hoes or other drilling devices either in a straightline or in V form, are provided atopposite sides with depending lugs or ears 14,

which are perforated for the reception of piv-- ots or pintles 15 for connecting the front ends of the drag bars or beams to the slides. The drag-bars or beams are preferably composed of two sides or members provided with forwardly-converging front portions having their terminals 16 arranged at the outer faces of the lugs or 'ears 14 and pivoted to the same by the said pivots or pintles 15, whereby the drag bars or beams are ada ted to swing upwardly and downwardly or throwing the drill-hoes into and out of operation and also for arranging'them at the desired depth.

The drill-holes 13, which are provided with tubular shanks or stocks 17, are suitably secured to the rear ends of the drag bars or beams, and when the machine is operated on clean ground they are arranged in a straight line; but when the grain-drill is used on trashy ground the hoes are arranged in V form, those at opposite sides of the center forming two rows which diverge rearwardly and which are adapted to work the trash laterally and discharge the same at the sides of the machine. This arrangement of the hoes is effected by means of a pair of levers disposed transversely of the grain-drill and located at opposite sides of the median line thereof andcentrally pivoted, by means of bolts 19 or other suitable fastening devices, to the adjacent longitudinal drag-bars 3. The transversely-disposed levers, which are arranged substantially in a horizontal position, are provided at intervals with longitudinal slots 20 for the reception of studs or projections 2 1 ofthe slides, which move longitudinally of the machine. The studs or proj ections 2 I extend from the upper faces of the slides, andwhen the transverse leversare oscillated the slides at one arm of each lever will be moved backward and forw'ardand those at the opposite arm will be simultaneously moved in the opposite direction. By swinging the levers in alinement transversely of the machine the drill-hoes or other devices carried by the rear ends of the drag bars or beams may be instantly Y brought into a straight line, and by swinging the inner arms of the levers forwardly to the position illustrated in Fig. 1 of the drawings the drill-hoes may be arranged in V form. Any trash collected by thehoes in the latterposition will be ;worked to the sides of the grain-drill and discharged thereat. The movement of the carrying-wheels assists in effecting this discharge, as the hoes are located. between the same.

The inner ends of the transverse levers are upturned to form ears 22, and they are connected bylinks 23 with the sides of a forked or bifurcated shifting lever 24. The front ends of the links or rods are-angularly bent and have straight transverse portions which vare arranged in the perforations of the ears 22. The forked or bifurcated portion of the shifting lever straddles the rear end of a draft beam or tongue 25 and is pivoted by a transverse pin 26 to a bracket 27, which is secured to the bottoms of the central guidebars 3 and which is provided with a depending portion having a perforation or opening for the reception of the pivot-pin 26. The

' rear ends of the links .23 are provided with eyes which are linked into perforations of the sides of'xther forked or bifurcated portion of the shifting. lever. The shifting lever is adapted to be swung backward and forward to oscillate the transverse slide-actuating lever, and it is locked in the desired adjustment by means of a foot-lever 28, disposed longitudinally of the machine and fulcrumed near its rear end on the shifting lever by means of a rivet 29-or other suitable fastening device and having a substantially U-shaped front portion 30. The front portion 30, which straddles a longitudinal ratchet-bar 31, is

provided with a transverse flange or engaging portion 32, adapted to drop into any one of a series of notches or recesses 33 of the ratchet-bar 31. The front arm of the ratchetengaging lever is heavier than the rear arm, so that the front end will be maintained in engagement with the ratchet-bar by gravity. The rear end of the lever 28 is provided with a foot-plate 34, adapted to be readily depressed by the driver, a suitable seat being in practice provided for his accommodation.

The drag bars orbeams are swung upwardly and downwardly to throw the hoes into and out of operation by means of a pair of oppositely-disposed rock-shafts 35, journaled in suitable bearings at the center and sides of the supporting frame. These rock -.shafts are arranged at an angle and diverge rearwardly and are provided at intervals with downwardly and forwardly projecting arms 36, which are connected with the drag bars or beams. The drag bars or beams are preferably arranged in loops or stirrups 37, suspended from the arms 36 by short chains 38 or other suitable flexible connections. The rock-shafts are also provided at their inner ends with arms 39, which are connected by links 40 with an operating-lever 41. The operatinglever.41 has a lower forked or bifurcated portion 42, the sides of which are ofiset from the plane of the upper or body portion of the lever and which are pivoted to the main or supporting frame by a transverse pin 43. The pin 43 passes through an eye of a plate 44, which is secured to the main or supporting frame at the adjacent ends of the transverse bar 3. The operatingdever is provided at the sides of the lower forked or bi.- furcated portion with a pair of oppositelydisposed upwardly-extending arms 45, which are connected to the links 40. When the op erating-lever 41 is swung downwardly from the position illustrated in Fig. 2 of the drawings, the rock-shafts will be partially rotated and the arms 36 will be swung upwardly for raising the drag bars or beams. The drag bars or beams are'adapted to slide through the stirrups or loops, so that the longitudinal adjustment of the former will not interfere with the operation of the mechanism for raising and lowering the drag bars or beams.

The operating-lever is locked at the end of its rearward movement by means of a pivoted dog 46, extending upwardly from the main or supporting frame at a point in rear of the. draft bar or beam and provided with a slot 47 through which the operating-lever 41 passes. The lower end of the pawl or dog 46 is forked orbifurcated to receive an upwardlyextending portion of a plate 48 and is secured to the same by a pivot or pin 49. The plate 48 is secured to the central guide-bars 5, its front end being extended over the rear end of the draft bar or beam and its rear end being bent upwardly to form a support for the pawl or'dog. The operating-lever 41 is provided with a notch 50, forming a shoulder for engaging the pawl or dog at the lower end of the slot 47, whereby the lever 41 is locked against forward movement. The lever 41 a may be provided with other notches or any IIS other suitable means may be employed for locking the drag bars or beams at an inter mediate point to control the depth of the hoes.

The transverse rock-shafts are provided adj acentto their outer ends with short arms 51 which are located beneath and arranged to engage front arms 52 of longitudinal rockshafts 53, journaled in suitable bearings at opposite sides of the main or supporting frame and extending rearwardly to points adjacent to the shaft or axle and provided thereat with depending laterally-movable arms 54, which are curved or hook shape for engaging the grooves 55 of slidable clutch sections or members 56. The clutch sections or members 56 engage clutch-faces 57 of the carrying-wheels. The hubs 'of the carrying-wheels are extended at their inner faces to form clutch sections or members for cooperat ng with the slidable clutch sections or members 56, and the latter are provided with teeth, forming clutch-faces for interlocking with those of the carryingwheels. The slidable clutch sections or members 56 are connected with the shaft or axle by a suitable key or keyway or other suitable means for permitting the slidable sections or members to move into and out of engagement with the clutch sections or members of the wheels. The slidable clutch sections or members 56 are yieldably held in engagement with the clutch sections or members of the carrying-wheels by means of coiled springs.

58, connected with the front arms of the longitudinally-disposed rock-shafts. This construction will permit the carrying-wheels to move in either direction, and when turning the grain-drill the carrying-wheel at the outerside of the machine, or side describing the greater circle, positively actuates the feed mechanism.

The machine is also adapted to be backed without operating such feed mechanism, and when the operating-lever is swung backward to its rearmost position the front arms of the longitudinal rock-shafts will be swung upward, and the slidable members or sections of the clutches will be carried out of engagement with the clutch sections or members of the wheels for throwing the machine out of operation. This is automatically effected when the hoes are swung upward out of the ground.

The grain-drill is designed to be provided with three sets of hoppers 59, 60, and 61. The members of each set of hoppers diverge rearwardly and are arranged in parallelism with the transverse bars 2 and 3. The front hoppers are designed for sowing grass-seed broadcast. The intermediate hoppers are designed for containing any kind of grain which is sown in drills, and the rear hoppers are provided for fertilizer, which is distributed in the drills simultaneously with the grain.

The hoppers are provided at intervals with depending seed cups or casings 62 and 63, which contain suitable force-feed mechanism constructed substantially the same as that shown and described in an application for patent filed by me on or about July 26, 1905, Serial No. 271,341. The intermediate and rear seed-cups 63 and 64 are connected by flexible spouts or tubes 68 and 69 with the tubular shanks or stocks 17 of the hoes 13. The particular construction for feeding the seed and fertilizer and for planting the same in drills does not constitute a portion of the present invention, but is described and claimed in the said application, of which the present application is a division, and further illustration and description of such construction are deemed unnecessary.
