FEEDER FOR CLOVER-HULLING MACHINES.

SPECIFICATION forming part of Letters Patent N 0. 618,451, dated January 31, 1899.

Application filed February 12, 1898. Serial No. 670,016. (No model.)

To aZZ whom it may concern.-

Be it known that I, FRANCIS T. WRIGHT, a citizen of the United States, residing at Edinburg, in the county of Johnson, in the State of Indiana, have invented certain new and useful Improvements in Automatic Feeders for Olover-Hulling Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same reference being had to the accompanying drawings, which form part of this specification.

Myinvention relates to improvements in automatic feeders for clover-hulling machines.

It is well known that the customary manual operation of feeding dry clover into a cloverhulling machine is dangerous and unhealthful to the operator and that the attempt to automatically feed clover-hullers by means of an endless carrier or conveyer has proven unsatisfactory for the reason that in feeding clover having long straw the carrier is unavoidably clogged and choked up by the straw, thus requiring the service of an attendant, and that such feeding devices are not adapted to be readily attached to old or ordinary machines.

The object, therefore, of my presentinvention is to provide a cheap portable automatic feeding attachment for clover-hulling machines having a positive feeding movement feeding direct to the threshing-cylinder without danger of clogging, easily operated, and adapted to be conveniently attached to any ordinary clover-hulling machine by making a slight change in the front side of the hopper.

My invention consists generically ina traveling push-bar movable over a fixed table in cooperative relation'with the threshing-cylinder, and specifically in a push-bar or feeding device pivotally mounted at one end to a rotary shaft driven by power, the said feeding device having a semicircular sweep over the feeding-table and being directed in its vertical movements by a circular track whose sections are in varying planes and adapted for a direct positive movement.

The novel feature of my invention consists in providing a positive and direct feeding device for clover-hulling machines having a mode of feeding closely resembling the manual operation and adapted to prevent all danger of clogging or choking thereof.

In the accompanying drawings, in which similar reference numerals indicate like parts throughout the several views, Figure 1 is a feeding device, showing its pivotal connection with the actuating-shaft.

Upon the forward end 1 of any proper hulling-machine is revolubly mounted in the usual or other proper manner a suitable threshing-cylinder 2, having proper journalbearings 3. To the said forward end 1 and immediately adjacent to the threshing-cylinder is hinged in any prope rmanner a table 4, preferably of sheet metal, having an upright flange 5 upon its outer end and one side thereof. Upon the other side of the said table is arranged a proper base 6, which may be arranged either upon said table or at one side thereof and rigidly supported from the machine.

Upon the outer end of the base 6 is rigidly fixed the pedestal 7, having a proper journalbearing 8 for thehorizontal power-shaft 10, having upon its outer end a proper belt-pulley 16, connected to any desired power-transmitting pulley upon the machine.

Upon the outer edge of the pedestal 7 rises a proper supporting-stand consisting of an upright hemispherical basal flange 9, preferably integral with said pedestal and having an upright integral sleeve 11, provided upon its up-. per end with a horizontal annular flange 12, upon the upper face of which is rigidly fixed a circular track 23,11ereinafter to be described. In this upright sleeve 11 is rotatably mounted the vertical shaft 13, having upon its lower end the rigid bevel-gear 14, adapted for a meshing engagement with the smaller bevel gear-wheel l5, rigidly fixed upon the inner end of said power-shaft 10. The upper ex* tremity of the vertical shaft 13 is angular to better form a holding engagement with the coupling 17, having a central rectangular opening 18, Fig. 4:, to receive the said upper end of the shaft 13, and is firmly secured in position by a proper set-screw 19. This coupling 17 is providedwith a pair of horizontal lateral parallel lugs 22, having between them a bifurcation adapted to loosely receive the upper end of the arm 20, which is pivotally secured therein by the transverse pin or bolt 21, thereby afiording a limited vertical play of said arm 20.

The annular metallic track 23 has that portion thereof adjacent to the threshing-cylinder abruptly elevated, as shown in Fig. 1, and is rigidly secured to said annular flange 12 by proper holding-bolts (not shown) and by the supporting-braces 24. This track 23 has upon its opposite edges proper vertical flanges 25, thus forming a central groove or recess upon the upper face of said track, adapted to contain the traveling roller 26, which is pivotally mountedin the hanger 27, which in turnis pivotally mounted in a second bifurcated hanger 28, having a shank 29, adapted to be secured in a suitable opening in said arm 20 by means of a washer and a holding-nut upon its screw-threaded extremity. The rake-arm 20, Fig. 1, normally oblique in arrangement to the said shaft 13, has a horizontal integral portion at its upper and inner end, as shown, so pivoted, as described, to the upper end of the vertical shaft 13 as to permit a limited vertical adjustment of the feeding device upon the outer end thereof, hereinafter described, as the said roller 26 makes its circuit upon the said flanged track 23. To the lower or outer extremity of the said handle 20 is rigidly bolted or otherwise fixed the horizontal push-bar 30, adapted to sweep the said table 4 in its rotary swinging movement about the revoluble shaft 13, upon which it is fixed, and thereby automatically feed the contents of said table to the hulling-cylinder. The union of the said push-bar 30 with its operating-handle is still further braced and strengthened by the rods 31, 32, and 33, Fig. 1.

The above description refers particularly to that form of construction shown in Fig. l, the operation of which is obvious and, briefly stated, is as follows: The fixed belt-pulley 16,

. being connected with a proper sou-roe of power,

when set in motion rotates the power-shaft 10 and its rigid bevel gear-wheel in the same direction as that of the threshingcylinder,thereby actuating the bevel gear-wheel14 and the shaft 13, which carries with it the pivoted push-bar 30 in its sweep over the table 4, in the same direction as that of the hands of a clock, by which movement the clover which is first deposited by the operator upon said table 4 is by a regular and positive movement fed directly to the said threshing-cylinder. As the annular track 23 has that portion adjacent to the threshing-cylinder abruptly elevated and as the arm 20 has a pivoted connection with both the shaft 13 and the traveling roller 26, it is obvious that when the said roller enters upon the elevated portion of said track the push-bar 30 will be proportionally elevated, the pin 21 serving as a fulcrum for the handle 20 of said push-bar in its vertical adjustment. By this means the said push-bar or feeding device has a full sweep of the table at from its point of entrance thereon, as shown in Fig. 1, to the point of exit therefrom, which is a sufficient distance from the front face of said cylinder to properly escape the same, thereby presenting a direct and positive feeding movement without any possibility of clogging. Obviously aplurality of said push-bars may, if desired, be mounted on said shaft 13, all identical in construction and mode of operation.

It is obvious that my construction may be variously modified without departing from the spirit and scope of my invention, which consists in providing an automatic feeder for clover-hulling machines, comprising a fixed table adjacent to the threshing-cylinder, a traveling push-bar or a plurality of bars mov ing over said table in cooperative relation with said cylinder, and means for actuating the said push-bar.

Having thus described my invention and the manner of employing the same, what I desire to secure by Letters Patent is- A clover-hulling machine provided with a threshing-cylinder 2, a fixed feed-table 4 connected to said hulling-machine and provided with an upright flange 5 upon its outer edge, and rounded at its outer end; a supportingstand arranged upon one side of the table, a vertical shaft 13, mounted in said stand and provided with a driving-wheel 14:, at its lower end, and a driving-shaft provided with a driving-wheel at its outer end and a pinion at its inner one, combined with the arm 20 pivoted upon the upper end of the vertical shaft, a supporting-roller loosely connected to said arm, a cam-surface over which said roller travels for the purpose of raising and lowering the arm, and suitable push-bars connected to the lower end of the arm, and which bars are adapted to be raised and lowered by the roller and the cam, substantially as shown and described.

Signed by me, at Fort Wayne, Allen county, State of Indiana, this 5th day of February, A. D. 1898.

FRANCIS T1 VVRIGIIT.
