HAY-LQADER.

SPECIFICATION forming part of Letters Patent No. 406,699, dated July 9, 1889.

Application filed November 2'7, 1888 T0 all whom it 7mm] concern:

Be it known that I, HARRY L. BOTSFORD, a citizen of the United States, and a resident of Clifton, in the "county of Sully and Territory of Dakota, have invented certain new and useful Improvements in Hay-Loaders; and I do declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 is a side elevation of my improved hay-loader. Fig. 2 is a sectional elevation, and Fig. 3 is a plan view of the same. Fig. 4 is an enlarged detail plan view of the coupling-link F and its adj unctive parts. Fig; 5 is a detail view of the block T andwheel Q, together with their adj unctive parts.

This invention relates to improvements in hay-loaders; and it consists in the construction and novel arrangement of parts, as hereinafter set forth, and pointed out in the claims.

The loader is designed to be secured to the rear end of a hay-wagon and to be drawn therewith over the swath or windrow of hay, and the loader is so constructed that the rake may be released to pass over large stones or other obstructions by a man on the load of hay, and extension-legs are provided that may be lowered to the ground by the man on the load when it is desired to support the loader detached from the wagon.

Referring by letter to the drawings, A des ignates the inclined side bars of the draft or main frame, which are secured at their rear ends to the vertical bearing-strips 13, connected transversely by the hollow bar C, through which the driving axle or shaft D has its hearing. The shaft D has the drive-wheels E rigidly secured to its outer ends, and by placing the shaft within the hollow bar C the said shaft cannot interfere with or clog the hay while revolving.

To attach the loader to a wagon, the link F is provided, which is pivotally secured to the cross-bar G of bars G, depending from the elevator-frame Q, by means of a bolt passing through said crossbar and the open- SerialNo. 291,987. (No model.)

ing a in the link, which is elongated, so that the link may be moved lengthwise should it become necessary while coupling. The shank portion of the coupling-link is normally seated in the notch Z) in the frame H, which is secured to and projects forward from the crossbar G, and the arc slot 0 is formed in said frame, so that the link may be moved laterally while coupling to the coupling-pin din the block I, which is bolted to the frame-work or rack of the wagon, said coupling-pin being retained in its lower position by an encircling coiled spring (1'. A cord c extends from the pin (1 to any convenient point on the frame of the loader within reach of the person on the wagon, so that the pin maybe operated therefrom. J shows extension-legs adapted to move in the guides f, secured to the loader-frame, and having the racks K engaging with the gears L on the shaft M, having journal-bearings through the extended portion M of the elevator-frame, as shown. A crank N is secured on one end of the shaft M, by means of which the legs may be lowered to the ground from the load in the wagon when it is desired to disconnect the loader from the wagon, and a dog g, engaging with one of the gears, holds t-he'legs as adjusted either up or down.

O is an endless carrier turning on the pulleys P P, having journal-bearings in the elevator-frame Q. The journal of the pulley P is extended outward through the frame at one end, as shown, and has loosely mounted upon it the sprocket-wheel Q, which is driven by the chain R, and the sprocket-wheel S 011 the shaft D. The sprocket-wheel Q is provided with clutch-arms m, designed to engage with the arms at on the clutch-block T, which has an angular longitudinal opening adapt-ed to fit upon the extended angular portion 0 of the journal, which is long enough to allow the block to be drawn outward to disengage the arms or and m, thus throwing the carrier out of gear when it is'desired to transport the loader from' fieldto field. When drawn outward, the spring-keeperp, secured to the block T, enters the notch q in the angular portion of the journal and prevents the block from being wholly withdrawn.

A shows the spring rake-teeth secured at their upper ends to the bar B of the frame C, which has journal-bearings on the upper portion of the strips B, held therein, it may be, by button-like plugs (not shown) secured to said strips B and entering the unoccupied portions of the said bearings, and the said teeth extend rearwardly through the guidestaples a on the bar D of the frame 0, and thence downward and inward to a contact with the ground. The frame C is held rigidly in place by the dog I), pivoted at one end to the strip B and engaging at its other end with the barD, forming the lower end of the frame C, comprising the inclined side bars 01 secured at their lower or outer ends upon the ends of the shaft D, which ends are in turn supported in recesses in the brackets (1 secured to the strips 13. The lower or engaging end of the dog bhas an angular recess or notch, which receives the corresponding portion 12 of the shaft D. When it is desired to release the frame to allow the rake-teeth to ride over an obstruction, the dog I) may be released by means of a chain or rope c, which is secured at one end to the dog Z) and passes over a pulley c on a support or post 0 secured to one of the side bars (Z to a point at the upper end of the loader within reach of a person on the loaded wagon. The staples a, however, allow sufficient play for the teeth to ride over small stones or through small obstruetions.

,E is the feeding-roller, having the projections thereon, having journal hearings in the strips B near the lower ends, and the said feed-roller is revolved in'a direction opposite that of the endless carrier by means of the pinion F on the extended journal meshing with the pinion G on the shaft D.

H designates fingers secured to the rockshaft 1, journaled in bearings 011 the pendent bars or portions J, depending from the side bars. The said fingers normally stand at an angle with their lower ends toward the rake teeth, and are designed to ride upon the surface of the ground hay is raked up by or hay, so that when the the rake-teeth it will be piled upon the upper sides of the fingers, and the hay will be forced through the throat K to the carrier by the revolving feed-roller. These fingers 11 may be dispensed with when the loader is operating in long hay or grain; but in short hay, or hay thinly spread upon the ground, it is desirable to use the fingers, as described. v

A skeleton guide-board L is pivoted, as at L at its lower end within the elevator-frame above the endless carrier, and is designed to prevent the hay thereon from blowing off, its upper portion being suitably supported in position by across-bar L applied thereto and resting upon the upper edges of the elevatorframe Q. The object in pivoting the guideboard is so that the hay will not pile up or become choked 011 the carrier.

Having described my invention, .what I claim is 1. The combination, with the endless carrier, the pulleys, and the driving mechanism, the sprocket'wheel of the driving mechanism being loosely mounted on the extended journal of one of the pulley-shafts, the clutcharms thereon extending in opposite directions, of the clutch-block having the angular longitudinal opening engaging an angular portion of the extended journal, said angular portion having a notch, the vertical arms thereon, and the spring-keeper, substantially as specified.

2. The combination, with the loader-frame, the side pieces B, wheels E, the-shaft D, and the rake-teeth, of the rock-shaft having journaled bearings in the depending portions of the frame and located in front of the raketeeth, the rearwardly-inclined fingers secured to said rock-shaft, and the feed-roller having the projections and operated by the pinions on the wheel-axle, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
