FEEDING MECHANISM FOR GRAlN DRlLLS.

SPECIFICATION forming part Of Letters Patent 1\IO. 659,367, dated October 9, 1900. Application filedAngnst 8, 1900. Serial No. 26,299. (No model.)

To aZZ whom it may concern:

Be it known that 1, ROBERT GALLOWAY, of Bufialo, in the county of Erie, State of New York, have invented certain new and useful Improvements in Feeding Mechanism for Grain-Drills and I do hereby declare the following to be a full, clear, and exact description of the same, reference beinghad to the accompanying drawings, forming a part of this specification, and to the letters of reference marked thereon.

discharge-openings.

This invention relates to seeding machinery generally, but is more especially applicable to seed-drills, the objects of the invention being to provide a simpleand practical grain-feedingj'mechanism capable of handling and distributing evenly grain of difierent sizes and kinds and by adjustment to regulate the exact quantity of any size to be fed for a given distance.

To the above vends the invention consists generally in an improved feeding mechanism embodying double runs for the grain, with a single feed-wheel adapted to be adjusted for feeding the grain in either run at will and in quantities in proportion to the desired rate of feed.

The invention further consists 'in certain novel details of construction and combinations and arrangements of parts, all as will be now described, and pointed out particularly in the appended claims.

Referring to the accompanying drawings, Figure 1 is a top plan view of the bottom of a section of a grain-drill hopper,showing a conple of double-run distributors and a controlling mechanism for the feed-shaft. Fig. 2 is a vertical section through the cup and feeding mechanism, taken longitudinally of the feedshaft. Fig. 3 is an elevation looking at the Fig. 4 is an end elevation. Fig. 5 is a vertical section at right angles ,to the feed-shaft.

Like letters of reference in the several figures indicate the same parts.

For the purpose of illustrating the present invention I deem it necessary only to show that portion of a grain-drill to which the invention directly relates, and it will be understood that the other portions of the drill or seeding-machine may be of any usual or preferred type, the invention itself being capable of general application.

' In the drawings the part lettered A is a sec- .tion of the bottom of the hopper'of a drill,

and B is a feed-shaft adapted to be rotated-by any suitable power mechanism (not shown) and to be moved longitudinally for varying the rate of feed, as is common in some classes of single-run distributors, the shaft being moved longitudinally by a shifting lever O, pivoted at any suitable point on the frame and codperating with a spool C, fastened on the shaft.

In proper position for cooperating with the shoes or spouts for conducting the grain to the ground there are secured beneath the hopper-bottom suitable seed-runs, which in the present instance are in the form of double runs, each occupying one-half of acasing D, preferablysecured to the bottom of the hopper, one run in each casing being adapted for a larger-sized grain than the other run, for which purpose it may be made slightly deeper, so as to more readily accommodate the grain. In the front-elevation these runs are indicated by letters E and F, and each in general conformation is similar to the runs heretofore employed in single-run distributors of this same character, The feed-shaft heretofore mentioned passes through all of the runs and is journaled so as to rotate in the cutofis H, mounted in opposite sidesof the casing and adapted to move longitudinally into and out of the casings, so as to close more or less the runs through the casing.

Forthe purpose of so closing the runs and of pre-.

venting the seed from passing through the casings in the wrong direction the cut-offs H are provided with wings h h, as shown, and between them there is mounted, so as to rotate in unison with the shaft, a fluted feed-- wheel K, adapted to project more or less into either run in accordance with the longitudinal adj ustment of the shaft. In the preferred construction this fluted feed-wheel is adapted to slide longitudinally through a central disk or rosette L, journaled in the casing and constituting the major portion of the dividing-wall between the two runs, the upper portion of said wall being formed by a bridge M, held in position in the casing by projecting lugs m and having a downwardly-extending flange m on one side, against which the disk takes a bearing for preventing fine seed from Working over from one run to the other. In this preferred construction also the rotary disk is of such size and the channel for it so formed that said disk may extend down to the bottom of the larger or deeper run for the purpose of effecting a more perfect and complete feeding of the grain in the larger run and, also for preventing the passage of the grain from one run to the other, as aforesaid.

As a convenient construction in the practical manufacture of the double-run seeding mechanism, as before described, the feedshaft is square and the fluted feed-wheel K is provided with a central diaphragm k for imparting rotation to the feed-wheel. The cut-off devices and feed-wheel .are provided with cylindrical projections and bearings 70', adapted to cooperate for centering said outoff devices and feed-wheel at their meetingpoints, while the outer ends of the cut-off devices are supported by inwardly-extending cylindrical projections 07,, formed on disks or hubs N, fitting on the squared shaft and held .in posit-ion by cotters or other suitable devices at opposite ends, whereby when the parts are assembled the feedrwheel will be held centrally between the cutofi devices and the entire mechanism will be accurately centered and positioned on the feed-shaft with- .out thehecessity of separately fittingand attaching each part thereto.

The controlling-lever for the feed-shaft is adapted to register with two scales marked on a suitable quadrant and reading in opposite directions, for in operation it is obvious that when one run is in use a scale must be provided for indicating the projection of the I -feed-wheel into that run, and thereby indi- 'on a center immediately eating to the operator the quantity of grain which will be fed by that run; but when the opposite run is in use the adjustment of the feed-wheel is in the opposite direction, and a second scalemust be provided for giving the vdesired indications of the projection of the feed-wheel in the latter run. 7

In order to control which run shall be operative, a gate or cut-01f is provided in the hopper-bottom for closing one or the other of the runs at will. As shown, this gate or cutoff is in the form of a flap-valve O, mounted above the partition between the runs, and is adapted to be turned in one direction or the other, so as to close; one or the other of the runs, by means of a handle P, and, if desired, suitable indicatingmarks may be placed on the valve for showing which run is adapted to handle certain kinds of grain. For instance, one side of said Valve may be marked Wheat and the opposite side Oats.

In operation now the farmer or attendant after having set the flap-valve in accordance with the kind of grain to be handled may then adjust the feed-wheel into or outof the run, so as to feed any desired quantity of grain, this being easily determined. by reading the scale for that run in connection with the controlling lever.

It will he observed that with the present invention but a single feed-wheel is necessary and that with that single feed-wheel the capacity of the, machine for feeding accurately and without injury different sized grains and difierent quantities of the different-sized grains'is attained. Thus not only is the mechanism perfected and greatly simplified, but the parts may be indefinitely duplicatedand mounted in very small compass,

so that the drills may be' run close together,

itself.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
