JAMES DROMMOND SCHOFIELD, OF DALLAS, TEXAS.

PLANTER.

SPECIFICATION forming part of Letters Patent No. 777,754, dated December 20, 1904. Application iiled April 30, 1904. Serial No. 205,658.

To f/,/ whom t may concern.-

Be itknown that I, JAMES DRoMMoND SoHo- FIELD, a citizen of the United States, residing at Dallas, in the county of Dallas and State of rlexas, have invented certain Improvements in Planters, of which the following is a specification. l

This invention relates to improvements in l planters, particularly to that class commonly known as "riding-planters.

Various objects will be found to be embraced in my invention; but among the most important are to adapt the planter to cover an),7 depth desired, ,jet at the same time have its covering-shovels flexibly supported or pressed to their work, thereby permitting' the heavier furrow-opening shovel to be run at different depths in uneven ground and the coveringshovels to follow and cover at a uniform depth regardless of such unevenness; to provide an improved lifting mechanism and an improved connection between the furrow opening and covering shovels and framework; to provide a novel and convenient mechanism for adjustably and movably supporting the hopper and other portions of the planting mechanism, and for taking up or compensating for the slack of the chain connection between the driving means and the hopper-feed and maintaining these parts in the same rela` tive positions.

Variousother objects and advantages of the invention will hereinafter appear, and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a plan view of a planter embodying my invention. Fig.2isaside elevation of the same. Fig.3isa perspective view of the planter, the running'- gear and frame broken away to avoid confusion. Fig. 4 is a detail in plan of the hoppersupport, thev hopper removed; and Fig. 5 shows details in perspective, disconnected, hereinafter referred to. A

Similar numerals of reference indicate similar parts in all the figures of the drawings.

The machine is supported by the axle 1, at the ends of which are located the usual groundwheels 2, secured upon and moving with the axle. To the tongue or center-beam 3, at a point somewhat in advance of its rear end, are pivotally connected, by means of a transverse bolt 4L, the front converging ends of the side beams 5, which comprise the main or draft frame. Bearings 6 are provided upon the two side beams, and within the same is journaled the axle 1. A seat 7 for the accommodation of the driver or operator is mounted upon an arched standard 8, the terminals of the arch preferably having a series of bolt-holes 9, in any two of which bolts 10 may be located for the purpose of adjustably securing the standard to the side beams 5. A pair of inclined brace-bars 11 may be bolted at their front ends, as at 12, to the side beams 5 and have their rear ends provided with series of boltholes 13 for the accommodation of bolts 14, whereby the standard and seat 7 may be given any adjustment necessary or desired to properly maintain it in relation to the planter.

15 and 16 designate, respectively, the front and rear furrow-opening shovels, the same being supported at the lower ends of the usual divided shovel-standards 17 and 18, respectively. A pair of braces 19 may be bolted at their rear ends to the rear standard 18, as at 20, and at their front ends, as at 21, to the front standard 17. A similar inclined brace 22 may be bolted by the bolt 21 to the front standard and at its front end bolted to the under side of the beam 3, as at 23. The front standard 17 is provided with the usual boltholes 24 for the accommodation of the bolt 25, by means of which said standard may be adjusted with relation to the rear shovel 16.

Securely bolted to the opposite faces or sides of the beam 3 are opposite angled fulcrumplates 26, the vertical upper ends of which project above the beam 3, and each is formed with an elongated opening' or slot 27. Fulcrumcd in, and therefore passing` through and beyond the two slots 27, is the center cranked portion 28 of a transverse crank-shaft 29, which beyond the crank portion has its ends oppositely disposed to form journals, the latter being loosely mounted in opposite bearings 30, located upon the side beams 5. A short arm 31 may be disposed at an angle to and form one end of the crank-shaft, and an expansion-spring 32 may have its front end IOO connected thereto and to the adjacent side beam 5, said spring, as will be obvious, exerting a tendency to elevate the cranked portion of the shaft 29, and hence the rear portion of the main beam 3 and the hereinafterdescribed planting mechanism carried by or connected therewith.

A hopper-supporting frame 37, comprising an upper horizontal rectangular frame 33 and a depending inverted-U-shaped branch 34, has the lower ends or terminals of the latter pivotally connected by a transverse bolt 35 to the opposite sides of the shovel-standard 18. Opposite bearing-ears 36 rise from the opposite angles or corners of the rocking frame 37, and within the same is mounted the trunnions 38 of a hopper 39, said trunnions being located at the front and upon the under side of said hopper. Of course the hopper itself may be of any construction, and for that reason it is not necessary to go into the details of the same. At the rear ofthe upper horizontal rectangular portion of the hopper-support I may locate a rest-lug 40, upon which said hopper is supported at its free rear end when in actual operation. For operating the feed devices or mechanism within the hopper I may journal within the rear part of the frame 37 a transverse counter-shaft 41, the same having a tappet or any other means for transmitting the necessary motion. A sprocketwheel 42 may be carried by one end of the shaft, and a sprocket-chain 43 may connect the same to a sprocket-wheel 44, keyed upon or otherwise fastened upon the axle 1, and therefore moving therewith.

Loosely suspended from the shaft 41 and extending rearward and converging to a point between said shaft and the axle 1 is a pair of brace-rods 45, the same merging at their rear extremities into clamping- plates 46 and 47, respectively. The plates are provided with upper and lower lianges 48, and each plate is formed with an elongated slot 49, designed to receive an adjusting-bolt 50. An arm 51, having a bearing-eye 52 loosely journaled upon the axle 1, is engaged between the clampingplates 46 and 47 and `is provided at intervals with perforations 53, into any one of which the adjusting-bolt 50 may be located. Any suitable bearing may be provided for the eye 52; but preferably the hub 54 of the sprocketwheel 44 is extended to one side for this purpose, as shown. It will be obvious that by means of the construction described a comparativel y short drive-chain may be employed and that by a manipulation of the bolt 50 such chain, through the brace-bars 45 and their coupling, may be at a proper degree of tension.

Fast upon one end of the crank-shaft 29 an operating-lever 55 is secured and designed to operate the same for the purpose of raising and lowering the shovels. This lever extends to within easy grasp of the driver when perched upon the seat7. The leveris furthermore provided with a reciprocating springpressed pawl 56, operated by a handle at the upper end of the lever 55, the ratchet at the lower end being' adapted for engagement with a convenient tooth of a toothed segment 57.

58 designates the opposite draft-beams for carrying the covering-shovels, and the same may have their front portions upwardly disposed or curved, as at 59, and pivotally connected, as at 60, to the opposite side frames 5. A curved brace 61 may connect the rear ends of the beams 58, and beyond the points where it is bolted to the beams said brace may be inclined and bolted to the covering-shovel standards 62.

Through `slots 63, formed in horizontal extensions of the brackets 26, extend the upper vends of suspension-links 64, said links being provided above the slotted brackets with suitable stopsfin this instance cotter-pins 65- whereby a loose connection is formed. The lower ends of the suspension-links are pivotally connected, as as 66, to the beams 58, and upon each link between its two points of connection is mounted a compression-spring 67, whereby when the covering-shovels are lowered they are held yieldingly to their work and will cover uniformly regardless of the irregularities of the field. Also loosely hung upon the shaft 38, (see Fig. 4,) by means of ears 68, is the usual spout 69, the lower end of which is immediately in rear of the opening-shovel standard 18 and is loosely coupled thereto, as at 70.

A standard 71 rises from one of the braces 45 in rear of the hopper and may have formed in its edge one or a series of notches 72. A swinging pivoted handle 73 may be secured to the under side of the hopper, and after raising the rear end of the hopper until out of operative position with relation to the shaft 41 the hopper may be thus maintained by inserting the handle into engagement with any one of the notches 72.

By raising the rear end of the lever 55 the cranked portion of the shaft 29 is thrown forward to a substantially horizontal position, as shown in the drawings, thus lowering the rear end of the main or draft beam'3, the furrowopening shovels, and, in fact, all parts connected therewith and in rear of the bolt 4. A reverse movement of the lever 55 has a reverse effect-namely, the rear end of the beam 3, the shovels, and planting mechanism are elevated above the ground.

It will be observed that regardless of the position of the parts the hopper-supporting frame 37, being perfectly free to move upon the pivot-bolt 35 and being connected by the loose braces 45 to the axle 1, will always move or swing upon the arc of a circle of which the axle 1 is the center, and hence the sprocketwheel 42 always remains equidistant from the companion wheel 44. This eliminates entirely IOO IIO

the necessity of employing a long chain and numerous compensating idlers or other forms of take-up devices.

Pivotally connected to either covering-beam 58, (preferably the right) at or near the rear end thereof, as at 74, or at any other convenient point desired, is the front end of a footlever 75, the latter between its ends being fulcrumed on the axle 1 and in rear thereotl terminating in a foot-plate 76. By pressing down upon the rear end of this lever, the axle serving` as a fulcrum, it will be obvious that the covering-beams and the shovels carried thereby may be elevated momentarily for the purpose of becoming cleared of any accumulated trash.
