THOMAS LOGAN GRAY, OF NEW PROVIDENCE, TENNESSEE.

COMBINED GRAlN-PLANTER AND TOBACCO-HILLER.

SPECIFICATION forming part of LettersPatent No. 544,222, dated August 6, 1895.

Application filed October 13, 1894. Serial No. N 111011613 To all whom it may concern.-

Be it known that I, TEOMAS LOGAN GRAY, a citizen of the United States, residing at New Providence, in the county of Montgomery and State of Tennessee, have invented a new and useful Combined Grain-Planter and Tobacco- Hiller, of which the following is a specification.

My invention relates to a machine for hilling tobacco and planting grain; and the objects in view are to simplify and improve the construction and arrangement of the parts to produce a simple, inexpensive, and efficient mechanism capable of suitable adjustment and adapted to be operated by power derived from a ground-wheel or by foot-power.

Further objects and advantages of the invention will appear in the following descrip tion, and the novel features thereof will be particularly pointed out in the claims.

In the drawings, Figure 1 is a perspective view of a machine embodying myinvention. Fig. 2 is a longitudinal section of the same. Fig. 3 is a plan view to show the feeding devices and operating mechanism. Fig. 4 is a rear view, partly in section. Fig. 5 is a detail View in perspective of the pivotal frame which carries the furrow opening and closing devices.

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

The frame of the improved machine comprises the side beams l, connected near their front ends by a transverse bar 2 and at their rear ends by the upper and lower transverse bars 3 and 4, and connecting the beams at an inter-mediate point is a yoke 5, having its ends dropped vertically, as shown at 6, and then turned out horizontally to form the spindles 7, upon which are mounted the ground-wheels 8. The combined supporting and packing roller 9 is provided with a spindle 10, which is mounted in bearings at the centers of the upper and lower cross-bars3 and 4, at the rear end of the framework, said roller performing the function of a caster-wheel.

Resting upon transverse supporting-bars 11, which are attached to the upper sides of the side beams of the framework is a seedbox 12, preferably divided by means of a partition 13 to form a plurality of compartments 14 15, adapted, respectively, to receive grain and a fertilizing material. In the floors of the compartments of the seed-box are mounted the slides 16, provided with slots 17 and adjustable gage-plates 18, said plates being adjustable by means of screws 19 and slots 20 to vary the size of the openings 17. These openings 17 are adapted, when the slides are moved toward therear, to be closed by a stopplate 21, and when moved forward to register with outlet-openings 22, and mounted upon the slides are the cut-off plates 23, which are connected at their front ends to contractile springs 24, attached to the front of the seedbox. shoulders to engage similar stop-shoulders 26, whereby the rearward movement of the cut-offs is limited and forward movement is communicated thereto during the forward movement of the slides by the engagement of the gage-plates with the inneror rear ends of the cut-offs. In the construction illustrated the front ends of the seed-slides are connected by means of a cross-head 26, which is pivotally connected to an operating-lever 27, fulcrumed adjacent to one end upon a bearingplate 233.1; the front end of one of the side beams. V

Fixed to one of the ground-wheels is a driving or master gear 29, and fulcrumed on the frame adjacent to the plane of said gear is an arm 30, upon which is mounted the spindle 31 of a pinion 32, which meshes with said gear. The spindle of the pinion carries a crank-arm 33, to which is connected a rod 34, having at its front end a terminal stud 35 to engage a perforation 36 in the free end of the lever 27. The rear free end of the arm 30 fits in a guide or keeper 36 and said arm is normally held in such a position as to maintain the pinion in engagement with the gear by means of a coiled contractile spring 37.

Fulcrumed between the side beams in advance of the drivers seat 38 is a foot-treadle 39, said treadle having a spindle 40, mounted- This spindle termiin suitable bearings 41.

These cut-offs are provided with stop-' too l6 of the lever 27 or an extension of said lever beyond its fulcrum. Also connected to said crank-arm is a coiled return-spring 48, by which the arm and the c onnec'tingrod are returned to their initial positions after having been moved by the operation of the foottreadle.

It will be understood that either the groundwheel-operated mechanism or the foot-treadle may be employed as means for communicating motion to thelever27 to operate the seedslides, and to support the several connectingrods when they are not in use I provide hooks or keepers 49 and 50, located, respectively, at opposite sides of the framework.

Upon a spindle 51, which is arranged between the side beams at their front ends, is pivoted a frame 52, which carries the furrow opening and closing devices, said frame having side bars 53, which are connected at their rear ends by a yoke 54, and intermediate parallel bars 55, which are connected to the central portion of said yoke. Pivotally mounted between said intermediate bars of the pivotal frame 52 is a furrow-opening shoe 56, provided at its rear end with lateral cars 57, which are connected by means of coiled springs 58 with similar ears 59 on said intermediate bars. These springs are arranged to depress the rear end of the furrow-opening shoe and are adapted to yield and relieve the shoe of strain when the latter encounters an obstacle.

Pivotally mounted upon the side bars of the frame 52 are the furrow-closing shovels 60, having arms 61, to which are connected the springs 62 for holding the shovels normally in their depressed or operative positions. These springs also provide for the yielding of the furrow-closing shovels when the latter encounter obstacles.

Mounted upon a horizontal spindle 64,which is mounted in bearings in the arms of the yoke 54, are the pulverizing-disks 65, which are preferably concave in construction, said disks being adapted to follow the furrow-closing shovels to pulverize the soil on the surface preparatory to compression by the packingroller 9, hereinbefore described.

Mounted transversely in the framework near its rear end is a drum 66, and reeled thereon is a cable 67, which is connected to the rear end of the frame 52, whereby when said drum is rotated the cable is either reeled or unreeled to elevate or depress the furrow opening and closing devices. Pivoted to the framework adjacent to the drum is a handlever 68, connected at its lower end by means of a cable 69 with said drum, the cable 69 being reeled upon the drum in the opposite direction to the cable 67, whereby when the hand-lever is operated to unreel the cable 69 the drum is turned in the direction necessary to reel the cable 67 and thus elevate the furrow opening and closing devices. Attached to the hand-lever and arranged in operative relation with a segmental rack 70 is a springactuated locking-pawl 71, to hold the handlever in its adjusted positions.

This being the construction of the apparatus, the operation thereof is as follows: When the connecting-rod 43 is in engagement with the seed-slide-operating lever 27, and the connecting-rod 34 is engaged with the hook or keeper 50, the driver may operate the foottreadle to communicate motion to the lever 27. As the seed-slides are moved backward and the front ends of the gage-plates are removed from the adjacent terminals of the cut-offs a suflicient number of grains to form a hill pass through the opening or interval thus formed and rest upon the subjacent stopplate, and during the forward movement of the slides said intervals are closed by the contact of the gage-plates with the rear ends of the cut-offs, and the grains which have passed through said intervals are moved forward upon the stop-plate until the outlet in the stop-plate is reached. Thus the seed-slides receive the grain during their backward movement and discharge the same during their forward movement, and the adjustment of the gage-plates provides for regulating the number of grains which form a hill.

The operation of the furrow opening and closing devices will be readily understood without a detailed description thereof.

The hand-lever 68 is provided with an arm 72, which extends laterally under the arm 30, whereby, when the hand-lever is operated to elevate the furrow opening and closing devices, said arm 30 is elevated to disengage the pinion carried thereby from the mastergear.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
