IMPROVEMENT IN HARVESTERS. i
Specification forming part of Letters Patent No. 156,344, dated October 27, 1874; application filed March 10, 1874.
To all whom yit may concern:
Be it known that I, J EREMIAH HALL, of Shell Rock, in the county of Butler and State of Iowa, have invented Acertain new and useful Improvements in Harvesters; and I do hereby declare the following to bea full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon.
The nature of my invention consists principally, first, in a device for conveying the grain as itfalls on the harvester-platform to a receptacle formed `atthe inner end of the platform; second, in a device for lifting the grain from the receptacle in parcels of suitable size for bundles and placing them on the binding-ta- In order to enable others skilled in the art to which my invention appertains to make and use the same, 1 will now proceed to describeits construction and operation, referring to the annexed drawing, which forms a partof this specification, and in which- Figure l is .a plan view of a harvester embodying my invention. Fig. 2 is a rear elevation of the same. Fig. 3 is a side view of one of the cams used to operate the lifting device. Fig. 4 is a detailed view-of the reciprocating conveying carriage. Fig. 5 is: a sectional view.
A represents the frame of my machine supported at the inner end by the large driving or master wheel B, and at the outer end by a smaller wheel, B', which may be made adjustable up and down, asis Adone in some harvesters. Over the inner end of the frame is erected a vertical frame-work, G,.in which is secured the binders7 table D, directly over `the master-wheel B. E represents the platform of the harvester, which is slotted longitudinally,
as shown in Fig. 1, and from the inner end of the platform extends a concave longitudinallyslotted addition or extension of the platform upward to the edge of the binders table,which forms a receptacle, G, wherein the grain is collected to form a suitably-sized bundle, and is then carried up to the top of the binders table. On the inner side of the main driving or master wheelB is attached a cog-wheel, H, which gears with a pinion, a, on the end of a short shaft, b, running on a line in rear of and parallel with the axle of the driving-wheel. On the shaft b is a miter-wheel, ,which gears with a corresponding pinion, e, on the front end of the shaft f running at right angles with the former shaft. 0n the rear end of the shaft f is 'a crank, t', from which a pitman, I, connects with the rear end of a lever, J, pivoted in the frame A. The front end of this lever is pivoted to the cutter-bar K and operates the saine by the oscillating motion impartedl to it by the crank and pitman above described.
revolutions of the crank 'i' said carria e obtains a reciprocating motion. The carriageL consists simply of two parallel side bars connected by suitable cross-bars and sliding in grooves made in the longitudinal bars of the frame A under the platform E. In the carriage is a series of shafts, p p, each provided with a number -of curved teeth, n u. Upon one end of each shaft p is a crank, s, with projecting pin inserted in a hole, t, in a bar, M, placed at the side of and moving with the carriage. At each end of the path of the carriage L is a bumper, t, so arranged that the end of the b'ar M will strikethe same an instant before the carriage completes its stroke.
When the carriage reaches the end of its track, near the receptacle Gr, the bar M, having been stopped .by the bumper an instant before, causes the shafts p p toturn so as to throw the teeth an down below the surface of the platform, where they remain during the passage .of the carriage to the opposite end of the track. At this end, in like manner, by the stoppage of the bar M before the carriage is stopped, the teeth a a are thrown up through the slot-s of the platform, and are held in thisv position by friction, or a spring, or other suitb clc G. 0n the shaft h above described is a loosely-fitting pinion, w, which is revolved with the shaft by means of a clutch, fr, feathered on the shaft. This pinion w gears with a cog-wheel, N, upon the end of a shaft, y, which passes through the frame-work C below and parallel with the binders table D. On the inner side of the cog-wheels are two cams or camgrooves al. and b for operating the lifter.
The grooves a1 and b give motion to two levers, O and O2, and a groove, a2, on the inner` ends of lthe levers 0 Ol a shaft, P, has its bearings, and to this shaft are atttached the iin gers Z Z for lifting the grain up. The outer end ofthe lever O2 is connected by a rod, d1, with an oscillating stay, d2, which is pivoted .0n the same fulcrum as the lever O, and this stay is by a rod, d3, connected with a crank, d, on the end of the shaft P. To lift the grain from the receptacle G and place it on the binding -table D, the ends of the ngers Z are .brought down to the inner end of the platform of the harvester, when the cam-wheel N presses out the short arm of the lever O2, thus driving back the connecting-rods d1 d? the upper end ofthe stay d2 and the crank d4,
thus causing the shaft P to make part of a revolution until the fingers Z reach. a horizontal position or thereabout, when the cam,- wheels N N press down the short arms of the levers O 01, carrying up the other ends with the shaft P, during which motion the camwheel N so presses back the lever O2 and turns back the shaft P that the ends of the fingers remain nearly stationary, while the shaft is being carried up till it reaches a suiicient height to empty the grain carried up by the fingers on the table D, and then after the cam-wheels have made part of a revolution without moving the fingers or either of the levers, the cam-wheel N still further turns back the shaft P and throws back the lower ends of the iin gers till they stand in nearly a perpendicular position, when the long arms of the levers O O1 are again brought down, bringing with them the shaft P and the lower ends of the iingers to their starting point at the inner end of the platform E.
D1 represents the platform or foot board upon which the binder stands. Convenient to this foot-board and pivoted to the frame C is a treadle, R, connected by a rod, e', with .one arm of an elbow-lever, S. This lever is pivoted at its angle to the frame C, and at the end of its other arm is a loop, f7, through which passes one end of a pivoted lever, m. The other end of this lever is forked and iits 5r at@ in a circumferential groove on the clutch X. This clutch is held against the pinion w bya spring, n.
By depressing the treadle R with the foot the clutch X is thrown out of gear, hence the shaft h will revolve without turning the pinion w, and thus stop the motion of the grainlifting apparatus without interfering with the movement of the cutter-bar and grain-carrier, the object being to allow the grain to accumulate in larger quantities in the receptacle Gr before it is taken up by the fingers.
To enable the driver to do the work of distributing the bundles in convenient position for setting up on the `field, I arrange at the side of and near the rear end of the binders table a carrying-table, D2, pivoted or hinged to an arm, p', and operated by means of a compound lever, consisting of two bent levers, s1 and s2, united at t. The lower end of the lever s2 is attached to the carrying-table D2, and the forward end of the lever s1 is in position to be worked by the driver. In the lower arm ofthe lever s2 is a joint, t', which admits of its bending outward, when the forward end of the lever s is drawn back and tilting the table, but prevents it, after the end of the lever s1 is thrown forward, from bending any further inward, and thereby it forms a selfadjusting lock to prevent the table from being tilted by the weight of the bundles. It will be seen that this harvester is designed to save the labor of one binder. is accomplished by delivering the grain on the binding-table in parcels of suitable size for binding, where it is bound without removal to another place, thus permitting the binder to stand in the same position and do his work, and not consume his time in passing from one place to another. All this is secured by placing the binding-table directly over the master-wheel, as above described. It also relieves the binder from the labor and care of distributing the bundles upon the field by enabling the driver to do that work.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. The combination with the carriage L,- shafts p, and teeth n of the cranks s, sliding perforated bar M and bumpers o, all constructed substantially as and for the purposes herein set forth.
2. The combination of the cam-wheels N N', levers O 01 O2, rods d1 d3, stay d2, and crank d, all constructed as described, to operate the shaft P with its-fingers f, in combination with the receptacle G, substantially as and for the purposes herein set forth.
In testimony that I claim the foregoing a my own I affix my signature in presence of two witnesses.
