Specification of Letters Patent.
Patented Jan. 10, 1911.
Application filed March 13, 1909. Serial No. 483,615.
To all whom it may concern:
Be it known that we, HIRAM E. 'PURDY and ERLE W. MILLER, both citizens of the United States, residing at Rockwell City and Des Moines, in the counties of Calhoun and Polk and State of Iowa, respectively, have invented a new and useful Corn-Harvester, of which the following is a specification.
The object of this invention is to provide an improved construction for portable corn harvesters.
A further object of this invention is to provide improved means for driving corn snapping, corn husking and corn elevating devices.
A further object of this invention is to provide improved means for receiving and elevating husked corn. 7
Our invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in our claims and illustrated by the accompanying drawing, in which Figure 1 is a plan of the complete mechanism. Fig. 2 is a side elevation of the same. Fig. 3 is a rear end elevation of the same. Fig. 4 is a detail plan, partly in section, of a portion of the mechanism. Fig. 5 is a vertical Section on the indicated line 55 of Fig. 1. Fig. 6 is a cross-section on the indicated line 6-6 of Fig. 4, on an enlarged scale. Fig. 7 is a cross-section on the indicated line 77 of Fig. 6.
The snapping and husking mechanisms and conveying devices illustrated and described herein form the subject matter of a companion application executed by us on even date herewith and pending concurrently in the Patent Office, to which application reference is hereby made.
In the construction of the mechanism as shown, the numerals 10, 11 designate traction wheels, which also serve as supporting wheels and carry the major portion of the weight of the machine. An axle 12 is mounted loosely in the wheels 10, 11 and a rectangular frame is mounted loosely on the axle. The rectangular frame is constructed of side bars 13, 14, end bars 15, 16, a cross bar 17 connecting central portions of the side bars, longitudinal bars 18, 19 connecting the cross bar 17 and end bar 15, a cross bar 20 connecting the longitudinal bars 18, 19,2. draft bar 21 connecting the cross bar 17 and end bar 16 and brace bars 22 connecting: the cross bar 17, side bar 13 and end bar 16. An arch 23 is formed in and at one side of the center of the forward end bar 16 of the frame. Casters 24, 25 areswiveled to and support forward corners of the frame. A tongue 26 is fixed and braced to the end bar 16 of the frame on the opposite side of the center thereof from the arch and draft animals may be attached to said tongue by swingle-trees 27. One of the braces from the tongue 26 engages the forward end of the draft bar 21. A seat 28 is mounted on the cross bar 17. A gear-frame 29 is pivoted on and extends longitudinally of the axle 12 between the traction wheels 10, 11. Internal gears 30, 31 are mounted loosely on the axle 12 and abut end portions of the gear-frame 29 Tubular hubs 32, 33
are formed on the internal gears 30, 31 and said hubs are connected by ratchet andpawl devices of conventional form to hubs 34, 35 of the traction wheels 11, 10. The hubs 34, 35 are formed with peripheral flanges 34 (Fig. 7) within and loosely fitting the tubular hubs 32, 33. Rock shafts 34 are journaled in the flange 34 at diametrically opposite points and are operated by hand levers 34 on the outer ends thereof. Pawls 34 are mounted on the inner ends of the rock shaft 34 and engage at times with ratchets 32 on the hubs 32, 33. The pawls 34 are held in either position in which they may be placed manually by spring-pressed levers 34 fulcrumed on the flange 34 Thus is the motion of the traction wheels transmitted to the internal gears 30, 31 and thus is provision made for differential travel of the traction wheels.
A driving shaft 36 is mounted for rotation in bearings 37, 38 projecting rearward from the gear-frame 29 and pinions (not shown) on end portions of said shaft are received within and mesh with the internal gears 30, 31. One of these pinions is shown and described in our companion application frame of the machine. The forked frame 40 is located above and crosses the end bar 15 and cross bars 17 and 20 and extends through the arch 23. L- bars 41, 42 are bolted to and adjustable vertically on the sides of the arch 23 and the laterals thereof extend beneath and are adapted to support the forward end portion of the forked frame 40 at any desired elevation, thus providing for level or inclinedlocation of said forked frame. The forked frame 40 carries snapping rolls, husking rolls, conveying devices, a fly wheel, and gear connections driven by the drive shaft 36, and are fully described in our. companion application above men tioned.,
An elevator boot 43 is mounted in inclined position transversely of the rear end portion of the main frame and the lower end portion thereof is below an opening 73 in the rearend portion of the forked frame 40 and is adapted to receive husked corn from the rolls in said frame. A drag conveyer 44 is mounted for travel in the boot 43 and is driven in a common manner by a shaft 45 journaled transversely of and beneath the upper end of said boot. The upper end portion of the boot 43 iscarried by a standard 46' rising from the left rear corner. of the main frame. The shaft 45 is driven by sprocket gearing 47 from a counter-shaft 48 journaled in suitable bearings on the end bar '15 and longitudinal bar 18. A bevel gear 49 is formed'on the internal gear 41 and meshes with a bevel gear 50 on the forward end of the counter-shaft 48.
A wagon may be driven alongside this machine and receive husked corn from the top of the elevator boot 43.
In practical use of this machine the forked frame 40 is adjusted, as to inclination, by raising or lowering the L- bars 41, 42 in the arch 23 according to the condition of the corn to be harvested. If the corn is badly down the forward end portion of the forked frame 40 would be brought into close relation with the ground in order that it may gather and pick up the corn stalks. Then the machine is driven across the field,
I the driver occupying the seat 28, and the snapping and husking devices remove the ears of corn from the stalks and husk them and'the conveying devices carry the ears of corn along the snapping and husking devices and discharge them through the opening 73 as described in our companion appl ication'above mentioned. When the corn is discharged through the opening 73 it falls into the boot 43 and is elevated and dismultaneously without departing from the spirit of our invention.
