GEORGE WV. MURRAY, OF REMBERT, SOUTH CAROLINA.

. REAPER.

SPECIFICATION forming part of Letters Patent No. 520,892, dated une 5, 1894.

Application filed September 25; 1893. Serial No. 486,450. (No model.)

To a/ZZ whom it may concern/.-

13e it known that I, GEORGE W. MURRAY, a c1t1zen of the United States, residing at Rembert, in the county of Sumter and State of South Carolina, have invented a new and useful Reaper, o-f which the following is a speci- My invention relates to reapers; and the objects in view are to produce a cheap and simple construction of machine adapted to reap small grain, to gather the same into bundles, and to automatically dump the bundles at proper intervals upon the ground,

whereby said grain may be readily gathered.

Other objects and'advantages of the inventlon will appear in the following description, and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawingsz-*Figure 1 is a plan view of a reaper embodying my invention. Fig. 2 is an end elevation thereof. Fig. 3 is a front elevation of the same with the front bars of the framework removed to show the construction in rear thereof. Fig. 4.1s a rear elevation of a portion of the carr1er-frame. Fig. 5 is a similarv view, the parts being in a dierent position from that shown in Fig. 4. Fig. 6 is a detail view in perspective of the bell-crank rocking lever.

Like numerals of reference indicate like parts in all the figures of the drawings.

In the practice of my invention I employ an oblong framework, which in the present instance comprises the opposite side frameloars 1, the front and rear cross-'frame- bars 2 and 3, respectively, the former having attached thereto any ordinary draft device, as

i forl instance, the bail 4. The framework furat its outer ends.

ther comprises intermediate cross-bars 5 andV 6. The frame bars 1 between the rear crossbar 3 and the intermediate cross bar 6 are provided with bearings in which is journaled the transverse axle 7 having ground-wheels 8 This axle has a sprocket Wheel 9 fixed thereon to revolve therewith and also has splined at one sideA of the sprocket-wheel a master gear 10, whose hub is grooved to receive the lower forked end 11 of a shifting hand-lever 12 that is fulcrumed on a standard or yoke 13 that straddles the axle and has its terminals secured to the bars 3 and 6. A pair of handles 14 is boltedto the frame bars 1 and are connected at their rearends by a tie-rod 15, beyond which the handles are shaped to produce suitable handholes.

Arranged longitudinally opposite each other in the bars 5 and 6 are bearings, in which is j ournaled a short longitudinal shaft 16. This shaft 16 accommodates a sprocketwheel 17, and projects beyond both bearings. The front end of the shaft terminates in a crank 18, while the rear end has arranged thereon a pinion 19 which may be engaged by the master-gear 10 and thereby revolve as the Vaxle rotates, or, on the other hand, by means of the shifting lever the said master gear 10, which is splined on the shaft, may be moved away from and out of contact with the pinion, and the latter therefore remain idle.

Extending from the right side of the machine and suitably secured thereto are the carrier frame-bars 20, which are connected at proper intervals by suitable tie-rods to render them rigid with relation to each other. This frame at its front side is provided with fingers 21, and mounted for reciprocation between the fingers is the knife or cutter-bar 22. Pivoted as at 23 to the under side of the frame is a vibratory lever 24, the front end of which is pivoted at 25 to the inner end of the cutter-bar or knife 22, while the rear end is pivoted as at 26 to a pitman 27, whose inner end is by means of a link 23, to which it is pivoted at 29, pivotally connected to the inner end of the crank 18 of the shaft 16, so that as will be obvious,'the rotations of the shaft 16 will be communicated through the vibratory lever to the cutter-bar or knife, which will be rapidly reciprocated between the fingers and hence cut all grain admitted thereto.

Rising from the opposite bars l at the front of the machine is a pair of vertical standards 30, whose upper ends areconnectedby a tierod 31 and which are braced apart by means of an X-vbrace or frame 32, whose ends are mortised in the faces of the standards. This frame is suitably braced and is rigid, and is provided with transversely opposite bearings for the accommodation of a transverse shaft 33. The shaft 33 has a sprocket-wheel 34 thereon and receives its motion through 'the medium of a sprocket-chain 35 from the IOO sprocket-wheel 9 of the axle. One end ofthe shaft projects beyond one of the standards and has fitted thereover and secured thereto a rcel-head 36 provided with radial reel-arms 37 connected by blades 38, the reel thus constructed being designed to revolve over the carrier-frame and to `feed the grain to the cutters.

Inner and outer shafts 39 are arranged in the carrier frame-bars 20 adjacent to the inner and outer ends thereof, and the inner shaft is provided with a sprocket-wheel 40 which is revolved through the medium of a sprocketchain 4l that is in engagement with the sprocket-wheel 17 of the short longitudinal shaft 16. The two shafts 39 of course accommodate rolls, and thelatter are connected by an endless apron or belt, designated as a carrier 42, and which moves toward the outer end of the carrier-frame. The frame-bars 20 of the carrier are provided with openings, and in the same are mounted loosely the spindles 43, whose rear ends below the frame-bars are forked and have journaled therein casterwheels 44. The length of the spindles exceed the width of the bars 20, and coiled springs are located between the forks of the spindles and the under sides of the bars 20. A vertical bearing-eye 46 is located at the front of the main frame, and in the same a vertical spindle 47 is loosely mounted or swiveled and may be adjusted through the medium of a bindingbolt 4S or any other desired means. The upper end of the spindle is provided with a han dlever 49, whereby it may be moved to the right or left, the rear end of said lever eX- tending adjacent to a seat 50 employed for the accommodation of the operator, and supported upon suitable standards rising from the framework. The lower end of the spindle 47 is forked and receives a caster-wheel 5l. A bracket-arm 52 of L-shape is secured to the fork and projects upward in front of the framework. A coiled spring 53 is arranged upon the spindle between the lower end of the bracket-arm and the under side of the eye 46. A lever 54 is connected with the upper end of the bracket 52, has an opening in it to loosely receive the spindle 47, and projects to the rear under the lever 49. This lever 54 may be depressed, and by so doing the en-l tire framework will be depressed against the tension of the springs 53 and 45, so that the cutting-mechanism will sever the grain nearer the butts. The lever 54 may be locked in this position by means of a notched locking-standard 55, rising from the framework. By releasing the lever, the springs react to elevate the frame work and the cutter, so that the latter will sever the grain near the tops. 1 also provide means for raising and lowering the reel, and for this purpose I provide the standards 30 withaseries of transverse notches 56, in which I removably seat metal bearings 57 which are provided above and below their centers with openings for the reception of bolts 5S and between the same provide the rear sides of these bearings with transverse ribs 59 designed to take into the recesses '56.

Beyond the outer roll-shaft 39 upon which the carrier 42 is mounted I arrange a transverse shaft 60 and provide the same with a series of curved arms 6l. These arms are arranged normally under the outer end of the carrier and are yieldingly supported in such position by means of a coiled spring 62, whose outer end is attached to a bracket-arm 63 extending from the end-of the carrienframe. From the rear end of this shaft GO extends a rock-arm 64, whose outer end is pivoted as at 65 to a link Gwhose rear end is pivoted as at 67 to a curved arm (i8 that extends inwardly toward the main framework of the machine. There also extends from the shaft 60 a bellcrank lever G9 whose inner end is splined upon the shaft 60 and beyond which said shaft extends and is provided with a head 70. Interposed between this head and the bellcrank is a coiled-spring 7l which bears against the bellcrank and normally throws the same inward. The outer roll-shaft 39 is provided with a cam 72 which revolves therewith, and the path of the same is normally uninterrupted. The grain falling on the carrier is, by the latter, carried to the outer end thereof, where it is delivered on the curved arms Gl and by its weight causes the said arms to yield and lower against the tension of the spring 62. This operates the bell-crank lever so as to depress the same against the side of the bar G8, which, as shown, is pivoted between its ends at '74, and the said bell-crank lever the free end of which is beveled upon its inner side as shown in Fig. 6 is deflected by said bar against the tension of the spring 7l so as to be moved outward against the head of the shaft 60 and is thus brought into the path of the revolving cam 7 2, whereby it is struck and a complete dumping of the grain takes place. Owing to the action of the spring 7l the bell-crank rocking-lever is normally held in the position shown in Fig. l, in which it is located above the bar 68, but when said rocking lever is partially depressed by thc downward movement of the arms Gl, the beveled side of the free end of said lever is brought into contact with the bar 68, thereby deilecting the lever and bringing it into the path of the cam. As soon as the grain is dumped, and the cam has traversed beyond the bell-crank, the spring 62 serves to return the parts to their normal position, thus leaving the cam free to rotate until a second gavel of grain has accumulated upon the arms 61, when the operation is repeated.

From the foregoing description in connection with the accompanying drawings it will be seen that I have provided a machine of simple and cheap construction, that is designed to cut grain near its tops or near its butts as desired, and maybe quickly adj usted for this purpose, and which will receive the grain, form the same into bundles, and conveniently and automatically at proper inter- IOO vals drop the same, to be subsequently readily gathered.

I do not limit my invention to the precise details of construction herein shown and described, but hold that I may vary the same to any degree and extent Within the knowledge of the skilled mechanic without departing from the principle or sacrificing any of the advantages thereof.
