IMPROVEMENT |N SEEDlNG-MACHINES.

Specification forming part of Letters Patent No. 131,253, dated September 10, 1872.

To all whom it may concern:

Be it known that I, J. M. GULLEY, of J efierson, inthe county of Green and State of Iowa, have invented a new and Improved Seeding Attachment for Cultivators; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing forming part of this specification, in which Figure 1 is a perspective view of the attachment partly broken away to show the construction, and Fig. 2 is a front view of one of the grain-feeders detached from the hopper.

Similar letters of reference in the accompanyin g drawing denote the same parts.

My invention relates to that class of seedingmachines in which a series of feed-wheels are placed within a hopper to lift and discharge the grain therefrom when rotated andhas for its object to improve the construction of such machines, whereby they are rendered more complete and efficient in operation. To this end the invention consists, first, in inclosing each wheel within a separate compartment whose upper half is adapted for removal, the grain being fed to the wheel beneath the walls of the compartment only. By this construction the hopper can be completely filled with grain without interfering at all with the movements of the wheels, while the latter are accessible for adjustment or repairs by removing the upper portions of the compartments. It consists, secondly, in the construction of the devices by which the grain is fed from the hopper to the wheels. It consists, thirdly, in the combination of the feeding devices and p the seed-slides with the inclosing compartments and the feed-wheels, as I will now proceed to describe.

In the accompanying drawing, A is the hopper of a seeding machine, and B the feedwheels, mounted at intervals upon a horizontal shaft, 0, havingits bearings in the ends of the hopper. in a narrow transverse compartment composed of lower fixed walls or partitions D, which afford additional bearings for the wheel-shaft, and upperremovable sections or boxes E, which fit over the wheels and extend to the top of the hopper. The removable sections rest snugly upon the walls D, and are held in place against lateral displacement by fitting their open ends 'partments of the liftingwheel. wheels B are constructed with a series of pe- Each of the wheels is containedin front of the seed-tube J, while the arms pass each side of such tube through the front of the hopper, as above described. By moving the slides through the front of the hopper the size of the feed-openin gs is adjusted to regulate the quantity of grain fed to thelifting-wheels. K K are cams pivoted to the front of the hopper so as to be turned against one arm of each slide for the purpose of holding the latter in the desired position. L are the feeders, mounted at difl'erent angles upon the shaft 0, in close proximity to the outside of the compartmentwalls. They are each composed of a bar of wood or metal, having beveled edges extending about half their length upon opposite sides.

These beveled or sharpened edges are made in the form of a reverse curve, m, as shown in Fig. 2, the outer portion of the curve being flush or nearly so with the flat side a of the bar. By this construction, when the shaft is rotated the'bars not only stir the grain in the hopper but force it with a pushing action through the feed-openings 9 into the com- The feedripheral shoulders, 0, upon which are arranged curved plate P, secured in place by the removable bolts or set-screws q. By this construction buckets or seed-cups are formed upon the wheel, as shown, to lift the requisite quantity of grain. I design to supply the machine with two or more sets of seed'cups, the several sets differing in size somewhat, and to substitute one set for another when it becomes necessary or desirable to change the quantity of seed to be sown.

When the machine is in operation with the hopper filled and the compartments closed, the rotation of the shaft 0 causes the bars L to feed the grain into the wheel-compartments, where it is taken up by the buckets and discharged into the seed-tube through the openin gs R in the front of the hopper. By constructing the hopper with compartments, as above described, the feed-wheels are rendered accessible for repairs, 850. The hopper can be completely filled with grain without obstructing the movements of the feed-wheels, because such grain is fed to the wheels at the bottom of the compartments only.

Having thus described my invention, what I claim is- 1. The closed compartments for the feedingwheels, consisting of the fixed walls D and the removable box F, arranged transversely of the hopper A, substantially as described, for the purpose specified.
