CORN-HARVESTER.

SPECIFICATION forming part of Letters Patent No. 555,406, dated February 25, 1896, Application filed June 20, 1895. Serial No. 553,438. (No model.)

To all whom it may concern:

De it known that I, IVILSON IV. SMITH, of Fritchton, in the county of Knox and State of Indiana, have invented a new and useful Improvement in Oorn-IIarvesters, of which the following is a specification.

My invention relates to improvements in corn-haiwesters, and has for its object to provide a harvester which can be drawn between two rows of corn to cut the same and deposit it in piles ready to be t-ied into bundles.

rl`he invention has also for its object to provide a machine of the character indicated which can be operated by a single attendant, and which is simple and cheap.

The invention consists in the particular construction and combination of parts, as hereina-fter fully described and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference refer to corresponding parts in all the views.

Figure l is a side elevation of the improvement. Fig. 2 is a section on line 2 of Fig.

Fig. is a plan view. Fig. 4C is a perspective view of one of the sprocket-wheels. Fig. 5 is a sectional elevation of the same, and Fig. 6 is a plan and partly sectional elevation of the sprocket-wheel and a portion of the chain.

A is a rectangular frame, consisting of the side bars u, and the cross-bars a2. The frame is supported in an inclined position, as shown, by the drive-wheels B secured to the axle C, mounted in the rear ends of the side bars u, and the caster-wheel D mounted in the front cross-bar u? of the frame. Upon the frame in front of the wheels B the platform E is secured, and below the platform and suspended from the side bars a by hangers f is the crossbeam F. The platform E and cross-beam F project beyond the sides of the frame, as shown.

In the projecting ends of the beam F the vertical shafts g, carrying the winged cutters G on their lower ends and the beveled pinions G2 on their upper ends, are mounted. The pinions Gr2 mesh with bevel gear-Wheels Il secured to the ends of the transverse shaft 71. mounted in the hangers f, and upon the said shaft between the gear-wheels II and the said hangers are secured the sprocket-wheels IVI?. The endless chains I pass around the sprocketwheels HV2 under guide-pulleys I2 on the side 55 bars of the frame and around the sprocketwheels J, hereinafter referred to, and secured to the axle C outside of the drive-wheels B, so that the shaft h will be revolved as the ma chine is drawn forward, and through the 6o medium of the pinion Gf2 and gear-wheels H rotary motion will be imparted to the Cutters G, Secured to the rock-shaft 1, mounted on the rear side of the cross-beam F, are the dumping platforms or droppers K, which re- 6 5 oeive the corn cut by the cutters G. The rock-shaft 7o is provided with a rearwardlyprojecting arm k', to which is secured the connecting-rod l, the upper end of which is secured to the foot-lever L mounted on the 7o platform E adjacent to the drivers seat M. By this construction the dumping platforms or droppers K can be held in an inclined position by the driver pressing upon the footlever L until they have received a sufficient 7 5 quantity of cut corn to form a bundle, when by releasing the foot-lever they will be lowered and the corn deposited on the ground.

AThese dumping platforms or droppers can be of any desired shape so as to hold and retain So the corn thereon, but I prefer to make them semicylindrical, as shown.

In order to catch the corn as it is cut and deliver it to the receiving platforms or droppers, I mount upon the projecting ends of 8 5 the platform E the endless chains N provided with the curved iingers N2. The endless chains N are driven by the sprocket-wheels O on the upper ends of shafts o, mounted in the ends of the platform E, and provided with 9o beveled pinions O2 on their lower ends, which mesh with the beveled gear-wheels Il. The chains pass around the said sprocket-wheels O and hanged pulleys P, mounted on shafts p on the platform E in rear of the shafts 0.

In order to take up the slack in the chains I, the axle O is mounted in adjustable bearings o in the rear ends of the side bars of the frame. Any suitable bearings may be employed, but in the drawings the axle is shown roo in slots in the rear ends of the side bars d of the frame, and the bearings c for the axle project through plates c2 on the rear ends of the side bars u, and are provided with nuts c3, so that by adjusting the nuts the axle can be adj usted to take up any slack in the chains. The sprocket-wheels J, instead of having their teeth projecting through the links of the chain, as is usual, engage the ends of the links. For this purpose the wheels are formed with two rows of teeth j, which project on opposite sides of the ends of the links, as best shown in Fig. G, and in order that the chains may hug the wheels closely annular grooves jg are formed in the periphery of the wheels to receive the joint of the chains.

'lhills Q are connected to the forward part of the frame by means of the shaft q passing through the side bars of the frame, or they can be connected in any other suitable manner.

The operation is as follows: The driver seated on the seat M presses with his foot upon the foot-lever L, which, as before described, holds the platforms or droppers K in an inclined position, and as the machine is drawn forward the corn will be cut by the cutters G and caught and delivered by the fingers N2 of the endless chains N onto the droppers K. As soon as a sufficient quantity of corn is received upon the droppers to form a bundle, the driver releases the foot-lever, when the droppers will by their own weight and the weight of the corn thereon drop down and deposit their contents upon the ground, it being understood that the corn being of a greater length than the droppers will come in contact with the ground as soon as the droppers are lowered, and that as the machine moves forward the droppers will pass from beneath it.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a corn-harvester,the combination with a wheel-supported frame provided with a transverse beam suspended therefrom, a revolving shaft mounted in the beam, and a cutter on the lower end of the said shaft, of a rock-shaft mounted on the rear side of the transverse beam and projecting beyond the end of the same, said shaft being provided with a rearwardly-projecting arm, a semicylindrical dumping-platform secured to the end of the said shaft, a foot-lever on the frame, and a rod connecting the foot-lever with the arm of the rock-shaft, substantially as described.
