CORN-PLANTER.

Specification of Letters Patent.

Application led March 27, 1908.

Patented Dec. 15, 1908.

Serial No. 423,740.

To all whom it may concern:

Be it known that I, EDGAR BLANEY, a citizen of the United States, residing at White City, in the county of Morris, State of Kansas, have invented certain new and useful Improvements in Corn-Planters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. v

The present invention has reference to corn-planters, and it resides, primarily, in the provision of an exceedingly simple and eiclent mechanism for changing the speed of the shaft which operates the droppers,V

whereby the speed at which the dro per plates rotate, and in consequence, the uration of the intervals between successive discharges therefrom, may be varied to suit the ground over which the machine is traveling, the various changes being effected during the time that the machine is in actual operation.

To this end, the invention comprises an axle-carried pinion having a series of concentric sets of teeth formed thereon and a shaft provided at each end with a pinion, one of which meshes interchangeably with the sets of teeth formed on `said axle pinion and is slidable upon the shaft, while the other, which is stationary, meshes constantly with a pinion carried b a shaft disposed in advance of and paral elwith the axle and having a driving connection with a third transverse shaft which in turn, operates the dropper mechanism.

More es ecially, the invention resides in the particu ar construction of the shaft which carries the sliding and fast inions above referred to; in the artcu ar devices employed for looking t e sliding pinion against displacement when engaged with one of the sets of teeth formed on the master or axle inion; and in the articular mounting of the ever for shifting tfie sliding pinion when released from engagement with the locking devices.

The invention will be readily understood from a consideration of the following detailed description, and its preferred embodiment is illustrated in the accompanying drawings, in which corresponding parts or features, as the oase may be, are designated by similar reference numerals in the several views.

Of the said drawings: Figure 1 is a fragmental side elevation of the improved machine. Fig. 2 is a top plan view. Fig. 3 is an enlarged detail section on the line 3-3 of Fig. 2. Fig. 4 is an enlar ed detail view of the operating lever and t e sliding pinion secured thereto.

Referring more particularl to the drawings, 6 designates generally, t e frame of the planter which, as shown, includes left and right hand side sills 7 and 8, and an intermediate sill 9 disposed parallel therewith. The several sills are provided with bearings for the axle 10 upon whose ends are mounted the traction wheels 11. Adjacent the right hand sill 8, the axle carries a pinion 12, upon which is formed a plurality of concentric sets of teeth 13, three sets -being shown in the present instance.

Located at the front end of the frame and disposed parallel with the axle, is a shaft 14 provided at opposite ends with pinions 15 which mesh with pinions 16 mounted on the shafts 17 which carry the feed plates or disks 18, said plates being disposed within the seed boxes 19 which are supported in any preferred manner upon the front ends of the side sills of the frame. The shaft 14, hereinafter termed the operator shaft, is further provided with a sprocket wheel 21 connected y a chain 22 with the sprocket member 23 of a combined gear and sprocket wheel mounted upon a shaft 24 located intermediate the operator shaft and the axle and disposed parallel with the same. The rotation of this last mentioned shaft is effected by means of the beveled gear or pinion member 25 of the combined gear and sprocket wheel above referred to, the rotation of said member being caused by the engagement therewith of a pinion 26 secured to the front, or

relatively stationary section 27 of a longitudinal shaft whose rear section 28, which is connected with said front section by a universal joint 29, carries a sliding pinion 30 adapted for interchangeable engagement with the sets of teeth 13 formed on the master pinion 12. The front end of the shaft section 27 has a bearing in a collar 31 loosely mounted upon the shaft 24.

The sliding movement of the pinion 30 is effected by means of a lever 32 pivotally mounted upon the sill 8 in such a manner as to be capable of both a forward and backward, as well as a sidewise swinging movement, said lever being rovided with a yoked lateral finger 33 which) engages a sleeve 34 formed upon said pinion 30, the sleeve havf a pinion carried by said axle and provided of the foregoing.

. the other end of said shaft and said operator -with reference to the other section thereof,

ing preferably formed therein a' circumscribl ing groove in which the yoke portion of said finger loosely fits. By -reason of thisv construction, it will be seen that the lever may j be swung to one side, to disengage the pinion 30 from the particular set of teeth 13 with which it happens to be engaged, and then swung forward or backward, to bring the pinion into alinement with one or the other of the remaining sets of teeth, after which the lever is returned to its original position, engaging the pinion with said set. This return movement of the lever is effected automatically by means of a retractile coil spring 35 secured at one end to said lever, and at the other end to a hook 36 carried by a vertical rod 37 secured to the beam 9 the lever being thus drawn inwardly into engagement with the teeth 3S which project laterally inward from the bight portion of an inverted U- shaped rack 39, the free ends of whose arms are likewise secured to the sill 8. This spring will therefore, be expanded when the lever is swung outwardly, to effect its disengagement from the teeth 38, and the swinging movement of the rear section 28 of the jointed longitudinal shaft.

It will be apparent from the foregoing, therefore, that the speed at which the operator shaft rotates, and in consequence, the duration of the intervals between successive discharges from the feed plates can be varied to suit the character of the ground over which the machine as a whole is traveling, by merely engaging the sliding pinion with the proper set of teeth formed ori the master or axle-carried pinion, the movement of said sliding pinion being effected by means of the swinging lever, as above described.

The machine, as a whole, may be propelled in any desired manner, but is preferably provided with a pole or tongue (not shown), which is secured to the front beam.
