HAY-LOADER.

S'PncrrrcA'rroN forming part of Letters Patent No. 659,382, dated october 9, 1900.

Application filed August 6. 1900. Serial No. 26.056. (No model.)

To all whom it may concern.-

Be it known that I, FRANK N. 'Tnissnn a citizen of the United States, residing at Dayton, in the county of Montgomery, State of Ohio, have invented certain new and useful Improvements in Hay-Loaders, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to machines for loading hay adapted to pick up the hay from the ground and elevate it to the wagon by means of forks attached to parallel bars, which bars are given a reciprocating and an u p-and-down movement by their attachments to a crankshaft at right angles to the bars.

The special purpose of my invention is to provide a simple, cheap, and effective method for supporting this .crank-shaft at the center` to overcome the liability of the bending and twisting of the shaft, which frequently happens when it is supported and journaled only at the ends/ This matter presents considerable difliculty from the fact that the central portion of the crank-shaft is inclined at an angle to the point of desired support, so that where a central bearing has been desired it has been customary to supply two shafts or to give an extra horizontal bend to the shaft at the center. It is. the object of my invention to provide this center bearing and support without any modification or change in the shaft itself, and this I accomplish by the special construction to be hereinafter particf ularly pointed out and claimed..

In the drawings, Figure l is a perspective view of so much of the hay-loader as will illustrate my invention. Fig. 2 is a cross-section of same. Fig. 3 is a detail front elevation of the central hanger.A AYFig. 4 is a side view of same. Fig. 5 is a front view of one of the crank-shaft castings.

A is the bed-frame of the hay-loaderA of the usual description, across which is mounted the usual crank-shaft B, forming a number of cranks across the frame. At the ends of these cranks are attached the vibrating rods O O, which rods carry forks on their lower sides, and by the rotation of the crank-shaft.

in any well-known way the rods and forks are "ings to be rigidly secured to the shaft.

given a reciprocating and up-and-down movementv to pick up-and carry forward the hay to the upper end of the machine. This construction is old and well known and need not be further described. The bed-frame and its operating parts are mounted on carryingwheels, and the crank-shaft is usually rotated by sprocket wheel and chain connection with the carrying-wheels of the loader. In order to obtain a central bearing for this crank-shaft, I provide as follows:

D D are semicircular castings provided with ears a, et, by means of which they may be bolted together to form a hub or fixed pulley With fianges b b and central groove c. v A diagonal recess d is formed in the abutting faces of these castings D D to receive and fit around the crank-shaft at its central point, and one of the castings is provided with a lug c to t within a corresponding recess in the crank-shaft to prevent the castings from sliding on the shaft and to enable the cast- These castings are thus secured at the axial center of the crank-shaft, so that the pulley thus formed will rotate with the shaft, the axis of the shaft passing through the center of the wheel.

y E is a top brace supported in brackets F F to the sides of the bed-frame and extending across the frame in line with the plane of the crank-shaft. Bolted to the middle of the top brace and depending therefrom are a pair of straps G G, curved around and fitting in the groove c between the flanges b b of the pul- .ley and bolted together at the'bottom, these straps thus forming a support and bearing for the pulley secured to the crank-shaft. In

this way a perfect support is obtained for the IOS) shaft, and a divided strap forming a bearing IO for said pulley, With a cross-brace supported on the frame to which said strap is secured, substantially as shown and described.
