HAY-HARVESTING MACHINE.

Specification of Letters Patent. Patented NOV, 11, 1913.

. Application filed June 2a, 1912, Serial n6. voaasr. Renewedflctober s, 1913. Serial No. 794,325.

To all whom it may concern Be it known that I, Cnarnnon A. SUM- WALT, a citizen of the United States, residing at Sterling, in the county of Rice and State of Kansas, have invented certain new and useful Improvements in I-lay-l-larvesting Machines, of which the following is a specification.

The present invention comp-rises an improved machine for gathering hay, such as clover, alfalfa, or the like, .1 and depositing the same on the field in piles or cooks.

A special feature of importance included in the lnvention is the provisionof a pecullarly operating conveyor or carrier which receives the hay and is actuated automatically by the weight of the load deposited thereon to carry said load from the machine to the point of deposit on the field over whichthe machine travels. i

. The invention involves certain other genral features of construction, the advantages of which will appear more fully upon reference to the following description and to the accompanying drawings, in which- Figure 1 is a side elevation of a machine showing the preferred embodiment of the invention. 1 Fig. 2 is an enlarged side view showing more particularly the mechanism by which hay is deposited upon the ground. Fig. 3 is a rear end view of the machine showing certain parts not clearly illustrated A veyer 28 and the valves for the apertures in the other figures. Throughout the following detail description and on the several figures of the drawings, similar parts are referred to by like reference characters.

Describing the invention specifically and referrin to the drawings, 1 denotes the frame of the machine which will be supplied with any suitable propelling means, that illustrated comprising a motor 2 of any conventional construction. The motor 2 is operatively connected by suitable gearing 3 with the rear aXle 4, the latter being suppliedwith ground wheels 5. At its front portion, the frame 1 is supported by the caster wheels 6 mounted as usual upon rotative standards 7 atthe upper ends of which are the rearwardly projecting arms 8. The arms Sform part of conventional steering mechanism for the machine, the latter mechanism comprising gears 13 and 14: connecting said arms 8 with the steering shaft 15 whichhas a suitable steering wheel 16. A seat 17 on a platform 18 at one side machine of the frame of the machine alfords a convenient locatlon for the operator to oversee the operation of the machine.

Near the. front end of the machine is a suitable casing 9 which incloses a fan, the

latter being driven by a power connection 21 leading to the engine or motor 2. EX-

tending rearwardlyfrom thecasing 9 is a conduit 26, the rear end portion ofr which has openings 27 S211Cl1'62t1"611l of the conduit :26 terminating sjust above a conveyor 28. The casing 9-has a receiving spout 24 made in'sections, and each sectionbeing adapted to be held elevatedby hooks 25 so that the spout may clear obstacles over which the asses. At the discharge end of the conduit 26 is a discharge spout 26. p

By reason of the arrangement of the receiving spout 24; of thecasing 9, it will be swiftly to the discharge end of the conduit. From the discharge spout 26 of the conduit 26, the hay falls downwardly upon a con of the spout 26. permit of escape of the air passing through the conduit 26 so that the hay may be discharged gently upon said conveyer.

The conveyor 28 is of special construction,

as before promised and comprises a frame 29pivotod at one end,as shown at 80, in Fig. 2-, to the frame 1 of the machine. The rear end of the conveyor which is of the usual bolt type, is adapted forslight swinging movementvertically, or toward and from the; ground. A secondary swinging frame 31 is mounted at the rear end of the machine upon an upright frame 1 carried by theframel and said frame 31 comprises spaced sides, the rear ends of which are fulcrumedatfil on the frame 1*. The sides of thefi'ame 81 have the normally inoperative drive wheels 32: ournaled thereon, said drive wheels being formed each with a. drive gear i The drivegears of the wheels 32 are normally in mesh with gears 34 carried by the frame 29 of the conveyor 28 and mounted directly upon the conveyer shaft 35 around which the belt of the conveyer passes and by which said belt is driven. A bail of somewhat U-form, shown at 36, is connected at its lower ends with the rear extremities of the frame 29 of the conveyer. and said lower ends are also utilized to con nect the frame 29 with the rear portions of the sides of the frame 31. In this manner, the frames 29 and 31 are'caused to swing together in raising and lowering. At its upper end, the bail 36 is operatively con-- veyer and associated frames 29 and 31 move downwardly toward the ground. Said downward movement will carry the drive wheels 32 into contact with the ground, whereupon they will begin immediately to rotate, transmitting their movement through the gears 33 and 34: to the conveyer shaft- 35. When the shaft 35 begins to operate, the conveyer 28 is moved to carry the load now supported thereby rearwardly of the machine until said load is discharged upon the ground in the form of a pile or cock. As soon as the cock of hay has been deposited upon the ground, the conveyer 28 will be relieved of the weight of said hay and under the action of the counterbalance 38, said conveyer will be raised to its normal position, shown in full lines in Fig. 3 and remain in such position until another load of hay is deposited thereon and causes it to automatically operate in the manner hereinbefore described.

It is contemplated that certain of the minor features of construction of the in vention may be modified in accordance with the broad spirit of the improvements, as hereinbefore presented and as permissible by reason of the scope of the appended claims.

Having thus described the invention, what is claimed as new is:

1. In a machine of the class described, the combination of a frame adapted to be propelled over a field, a conveyer mounted on said frame and adapted for bodily movement toward and from the ground, and means connected with the conveyer and operable by depression of the latter under the weight of a load to impart movement to said conveyer.

2. In a machine of the class described, the

combination of a frame adapted to be propelled over a field, a conveyer mounted on said frame and adapted for bodily movement toward and from the ground, means connected with the conveyer and operable by depression of the latter under the weight of a load to impart movement to said conveyor, and counterbalance means connected with the conveyer to maintain the last mentioned means normally inoperative.

3. In a machine of the class described, the combination of a support adapted to be propelled over the ground, a conveyor mounted on said support and comprising a frame adapted to swing toward and from the ground, counterbalance means normally holding said frame in a predetermined position, means for depositing material upon the conveyer, and means connected with the conveyor and operative when the load upon the conveyer'depresses the latter to thereby impart movement to the conveyer.
