SEEDER.

SPECIFICATION forming part of Letters Patent No. 787,467, dated April 18, 1905.

Application filed July 30, 1904. Serial No. 218,782.

To all whom it In/my concern:

Be it known that I, EDMUND K. REA, a citizen of the United States, and a resident of Kansas City, county of Jackson, and State of Missouri, have invented certain new and useful Improvements in Seeders, of which the following is a specification and which are illustrated in the accompanying drawings, forming a part thereof.

This invention relates to broad-casting seeders, and particularly to that class of devices when applied to wheel implements. Its objects are to secure simplicity of construction and action, to provide a seeder which may be applied to wheeled cultivators of various forms and sizes or to seed-drills or other farm implements, to provide improved means for operating the seeder from the carrying-wheel, and to suitably locate and provide for the adjustability of the seeder relatively to the shovels or similar parts of implements to which it may be attached. These various objects are attained in the structure hereinafter described and which is illustrated in the accompanying drawings, in which- Figure 1 shows a detail side elevation of a cultivator with the seeder applied thereto. Fig. 2 is a vertical central section of the seeding device. Fig. 3 is a detail, partly in elevation and partly in section, of the driving mechanism of the seeder. Fig. 4 is a sectional view on the line 4 4 of Fig. 3. Fig. 5 is a plan view of the hopper with its cover removed, some parts being shown in section. Fig. 6 is a detail section of the hopper on the line 6 6 of Fig. 5, and Fig. 7 is an elevation of a sleeve used in the device separated from other parts.

The frame of a cultivator is shown at 10 and may be of any desired form of construction. The axle of the vehicle is shown at 11, one of its carrying-wheels at 12, certain of its shovels at 13, the drivers seat at 14, and one of the handles by which it may be controlled when the operator is not mounted is shown at 15.

The seeding mechanism is designed to rest 3 upon and be carried by the wheel 12. It is provided with a hopper 16 for carrying the seed, and from this hopper there leads downseveral sections, as shown, its upper section being preferably a casting. This tube is open at its lower end and discharges upon a rotatable distributer 18, which may be of any desired form of construction. The seeding device is supported upon the wheel 12 by means of a friction-roller comprising a pair of heads 19 20, fixed upon a sleeve 21, which turns loosely upon a stud-shaft 22, projecting laterally from the upper section of the tube 17. One of the heads, 19, takes the form upon its outer face of a beveled gear, as shown at 23, which is adapted to mesh with an annular rack 24, running upon the tube 17 and supported by means of an annular shoulder 25 formed thereon.

The distributer 18 is carried by a shaft 26, which is preferably located on the axis of the lower portion of the discharge-tube 17, and this tube is bent or offset, as shown at 27, so

that the upper end of the shaft projects through 1 be provided and is shown as taking the form of a Worm-wheel 30, mounted upon a shaft 32, located across the interior of the hopper, the worm-wheel being provided with studs 31 for agitating the seed and being driven by a worm 33, secured upon the shaft 26 by a setscrew 34.

A gate or valve 35 is provided for regulating the discharge of the seed from the hopper and is shown as being in the form of a plate resting upon the hopper-floor and adapted to oscillate across the discharge-aperture. The gate 35 is secured to and controlled by acrankrod 36, projecting upwardly through the top of the hopper and carrying a crank-arm 37, which swings over a notched segment 49, secured to the rim of the hopper, so that it will frictionally hold the gate in any position to which it may be adjusted.

The head 19 of the friction-roller is secured to the inner end of the sleeve 21 by means of a screw 38. The head 20 is in threaded engagement with the sleeve 21, so that it may be adjusted relatively as to the head 19 for the purpose of adapting the roller to wheels of different width of tread. A lock-nut 39, running on the sleeve 21, secures the head 20 in its adjusted position. Each of the heads 19 and 20 is provided with a steel inner face, as shown at 40 41, each of these members being in the form of a truncated cone, so that their bearing-faces converge. By adjusting the head 20 upon the sleeve the depth to which the rim of the wheel 12 will enter the channel of the roller may be varied, thereby varying the speed at which the roller is driven by changing the diameter of the line of contact with the drive-wheel. A band 42 may be placed upon the sleeve 21 between the heads 19 and 20, so as to protect it from dirt or abrasion. This band may be of any suitable material, such as rubber.

The sleeve 21 being slidable upon the shaft 22 the gear 23 may be thrown into and out of engagement with the rack 24, and this movement is secured by means of a supplemental sleeve 43, loose upon the shaft 22 and engaged with thesleeve 21 by means of a collar 44, secured thereto, and fitting within an annular groove in the sleeve 43, so that the two sleeves are independentlyrotatable, but are locked against relative axial movement. The sleeve 43 is provided with an oblique camgroove 45, through which projects a pin 46, fixed in the shaft 22. This sleeve may be provided with a suitable handle 47, by means of which it may be turned, and the cam action moves it longitudinally as to the shaft and with it is moved the sleeve 21, carrying with it the friction-roller, so as to throw it into and out of engagement with the rack 24.

The seeder is held in place upon the wheel by means of a suitable brace-rod, as 48, leading from it to the frame of the machine, and it is stayed by means of a collar 50, through which the lower end of the discharge-pipe may freely slide and which is secured at the hub of the wheel 12 and preferably to the outer end of the axle 11, as shown.

In order to adapt the seeder for use upon drive-wheels of different diameters, its delivery-tube is telescopic in form, and a clip 52 is applied to the upper end of its lower section 51, so that the two parts of the tube may be securely clamped together. In adjusting the length of the tube the pinion 28 and worm 33 are loosened from the shaft 26, so that the latter may slide through them. An expansion-spring 53 is coiled around the lower end of the discharge-pipe and reacts between the collar 50 and the discharge-nozzle 54, secured to the pipe, and tends to hold the frictionroller to the wheel 12.

In use, as shown in the accompanying drawings, the seeder is mounted upon the drivewheel of the cultivator and secured by the brace-rod 48 and collar 50. Its friction-roller is adjusted so as to adapt it to the width of the rim of the cultivator-wheel and so as to allow this rim to enter the channel of the roller a suitable depth to secure the desired speed for the distributer. The hopper being supplied with seed and the gate having been set so as to discharge the same at the desired rate, the gear 23 is thrown into engagement with the rack 24 and the apparatus is ready for work. The seed may be thrown in any desired direction by turning the nozzle 54, which may be done by first loosening the clip 52.
