HARVESTER.

SPECIFICATION forming part of Letters Patent No. 519,019, dated May 1,1894.

Application filed June 29, 1393- Serial No. 7 (N0 modem To aZZ whom it may concern.-

Be it known that I, WILLIAM D. HARMON, a citizen of the United States, residing at Marysville, in the county of Union and State of Ohio, have invented anew and useful Harvester, of which the following is a specification.

My invention relates to improvements in harvestersand to that particular class thereof employed for harvesting corn.

The objects of the invention are to provide a machine adapted to be operated along one side of standing corn, to sever the same and carry it vertically to a common point where it is conveniently held to be removed manually; to provide new andimproved mechanism for accomplishing this function; to provide for a shocking device, whereby thecorn may be conveniently stacked for shocking and conveniently tied into shocks or bundlos; and to provide for a convenient dumping of the shock thus formed and a square settling of the same firmly upon the ground; and to arrange or adapt for a utilization of the driving power of the machine to the operation of the dumping mechanism both in the act of dumping and in the act of returning the parts to their normal position.

Various other objects and advantages of the-invention will appear in the following description and the novel features thereof will be particularly pointed out in the. claims.

Referring to the drawings:-Figure 1 is a plan view of a harvester embodying my invention. Fig. 2 is a horizontal sectional view through the front end 'of the machine or the gathering device. Fig. 3 is a vertical longitudinal sectional view of the machine. Fig. 4 is a'transverse sectional view through the dumping tables. Fig. 5 is an inverted plan. Fig. 6 is a detail in perspective of the shocking post. Fig. 7 is a transverse sectional view through the shifting mechanism for operating the dumping tables.

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

In practicing'the invention the framework may be constructed in various ways but is preferably constructed in the manner herein shown and described, wherein as Will be seen, I employ at opposite sides thereof pairs of longitudinal beams 1 and 2, the same being arranged parallel and the beams 1 being located at the outer sides. The beams 1 and 2 at the left side of the machine are of the same length as the inner beam 2 is at the right side ofthe machine and the beam-1 at the right side of the machine terminates in rear of the front end of these beams. The entire series of beams is connected through the medium of transverse beams 33, 4 and 5, and the whole su-pportsthe platform 6' which above the beams 1 and 2 at the left of the machine is cut away forming an opening 7, and at the right of the machine is likewise cut away at the front end thus leaving the beam 2 at said side projecting in front of said platform. Resting partly on the platform at this front cut away portion and partly on the beam 2 that extends beyond the same at the right of the machine there is a diamond-shaped frame'S, from the four angles of which posts 9, 10, 11 and 12.rise, and they in turn support an upper similar frame 13. At each side of the front post 9 of the series slotted bearing plates 14 are located upon the bars of the frames *8 and 13, and set-screws 15 pass through the plates into the bars. These bearingplates accommodate pairs of front vertical stub-shafts arranged vertically opposite each other, the same accommodating sprocket wheels 16. Metal plates 17 are located above and. at the sides of the posts 10 and they are provided with sprocket wheels 18, similar to those mentioned. In rear of the sprocket-wheels 18 shafts 19 are journaled in the frames 8 and 13 and extend above the upper frame and above each frame are provided with sprocket-wheels 20. A stub-shaft 21 is supported upon the platform Within the frame 8 and carries upper and lower sprocket wheels; 22 and 23. Sprocket-chains 24 connect each upper and lower series of sprocket- Wheels 16,18 and 20, that chain at the right passing around the lower wheels also passing around the idle sprocket 22, so that the corresponding chain at the lower idle-sprocket 23. These chains are provided at intervals with pins 24, and upon each pin there is located a triangular catch or hook 25. Guide-strips 26 are located with in the sprocket-chains and against these said the opposite side of the machine passes around 7 chains ride, so that the said hooks are prevented from swinging beyond a right angle to the chain to which they are attached.

Upon the platform at the right side of the machine and extending parallel with the rear sides of the frames 8 and 13 is a pair of parallel guide-bars 27, which are connected by vertical posts 28. These bars 27 at their front ends project beyond the side angles of the frames 8 and 13, and at their rear. ends proj ect beyond the rear angles of said frames and at the latter ends are provided with lateral extensions 29 connected by a vertical bar 30.

From the upper sides of the bars 27 at their front ends slotted plates 31 are secured by means of adjusting-screws 32. Vertical studs 33 are mounted on the plates and are provided with sprocket-wheels 34. In rear of the rear bar 28 a vertical shaft 35 is journaled in the horizontal bars 27 and above said bars are provided with sprocket-wheels 36, the two sets of sprocket-wheels being connected by sprocket-chains 37. Guide-strips are located at the inner sides of the sprocket chains, and triangular hooks are pivoted at intervals upon said chains.

At the opposite or left side of the diamondshaped frame upper and lower frames 38 are located at the rear inclined sides of the frames 13, and vertical posts 39 serve to support the upperframe above thelower. Slotted bearingplates 40 are made adjustable by set-screws 41 at the front ends of the frames 38, and stubshafts 42 rise from the plates and carry sprocket-wheels43. The rear angles of the frame 38 are occupied by sprocket-wheels, the outer wheels 44 being located upon a stub shaft 45 and the inner wheels 46 being mounted upon a vertical shaft 47. These Wheels 46,44, and 43 are connected by upper and lower endless chains 48 within which guide-strips 49 are located, as in the previous instance, and to which are secured pivotally triangular books 50 that ride against the strips and coact therewith in the manner heretofore specified, These frames 38 terminate slightly in advance of the extension 29 of the bars 27 so that they combine with said extension to form a pas sage. The chains being set in motion it will be seen that they will gather the stalks after they are cut and conduct them in a vertical manner through the two passageways 51 and 52 formed by the frames described to the points where the two passage-ways meetor intersect, from whence they will be caught by the hooks of the chains 48 and carried laterally to the short passage 53 formed by the rear end of the frames 38 and the extension at the rear ends of the bars 27. As the stalks make their exit from this passage-way 53 their upper ends are caught by an L-shaped arm 54 that projects from the outer side of the upper frame 38 and across said passage-way. A spring-arm 55 is mounted upon a stud 56 of the arm 54, and at its free end extends across the opening in the arm so as to form one side of the stalk-receiving frame or arm. It will be obvious, however, that the accumulations of stalks deposited in the arm and retained by the spring may be readily removed from time to time by an attendant, the spring-arm yielding readily to a suflicient pressure.

A stub-axle 56 extends from the beam 1 at the right of the machine, and upon the same is mounted the ground-wheel 57. Bearingstandards 58 rise from the beams 1 and 2 at each side of the opening 7 of the platform and support a shaft 59 which accommodates a ground-wheel 60 that is located in said opening.

In suitable bearings 61 located upon the beams 1 and 2 a transverse main shaft 62 is jourualed, one end of the main shaft,namely, that opposite the grain-wheel 57, being provided with a gear 63, which is driven by a gear 64 with which said shaft 59 is provided at one side of its center. The shaft 62 car ries a small spur gear 65 and transmits its motion received from the shaft 59 to a short longitudinal shaft 66, which shaft 66 is journaled in depending bearings 67 upon the under side of the platform and is provided at its ends with beveled gears 68 and 69, the former meshing with the gear 65, and the latter meshing with a beveled gear 70, which is located upon the lower end of the short vertical shaft 21. At one side of the gear 65 a similar beveled gear 71 is mounted upon the shaft 62, and it meshes with a beveled gear 72 which is located upon the lower end of the rear vertical shaft of the side frame 38, which shaft has its lower end projected through the platform. Beyond this gear 71 a beveled gear 73 is located upon the shaft 62, and it engages with and drives a beveled gear '74 located upon the lower end of the rear shaft 35 of the opposite side frame. Thus it will be seen that motion is imparted from the grain wheel to the several guide or carrier chains heretofore described in a manner that will be obvious at a glance.

Below the forwardly projecting portion of the frame 8 a finger-bar 75 is supported, and in the same works an ordinary reciprocating harvester knife or cutter-bar 76, one end of which is by a pitman 77 connected to a crankdisk 78 located upon the front end of a short longitudinal shaft 79, which is journaled in bearings 80 upon the under side of the platform to the left of the carrier-mechanism. The rear end of this shaft has a beveled-gear 81 which receives its motion from and meshes with. a gear 82 mounted upon the main transverse drive-shaft 62.

The platform of the machine terminates above the rear transverse beam 5, but the longitudinal beams 1 and 2 project rearward beyond the same to support the dumping-table. The rear ends of these beams 1 and 2 are connected in pairs by short transverse bars 83 and each has secured thereto a curved standard 84 in which is mounted a swiveled casterwheel 85, which supports the rear end of the machine. Between the two inner beams. 2 it will be seen that nothing intervenes, so that the framework is open from the rear transverse beam to a point between the casterwheels. This portion of the framework is covered by the sectional sliding-table 86 which surmounts the beamsl and 2. The table-sections are provided upon their under sides with inverted T-shaped slides 87, and the same are engaged by keepers 88 located transversely opposite each other, and upon the upper sides of the beams 1 and 2. Thus it will be seen that the table-sections may be slid together to form a solid platform or table or separated so that their inner ends or edges are vertically opposite the inner beams 2. Rack-bars 88 are secured to the under sides of the table-sections and extend transversely, and their teeth are engaged by gear-wheels 89 located upon longitudinal shafts 90 at opposite sides of the machine and supported in bearings between the opposite pairs of beams 1 and 2. One shaft 90 terminates immediately in advance of the transverse beam 5, though the one at the right extends up to the main transverse shaft 62. However, each is provided in front of the transverse beam with a beveled gear 91,and the two gears intermesh with beveled gears 92 which are located upon a short transverseshaft 93 journaled in bearings 94 located upon the inner longitudinal beams 2. The front end of thatshaft 90 at the front of the machine is provided with abeveled gear 94 immediately at the rear of the shaft 62, and upon this shaft 62 opposite an opening formed in the platform and in front of said shaft 90 a sleeve 95 is located, said sleeve being fixed. At each side of the sleeve upon the'shaft loose conical shells 97 are located, and at the inner ends of the shells beveled gears 96 are located, each shell and gear being adapted for movement loosely upon the shaft. Conical friction pulleys or gears 98 are located at the outer side of each shell, and mounted upon a splined grooved sleeve 99. These grooved sleeves are engaged by the terminals of an inverted U-shaped shiftingframe 100 made fast to a sliding bar 101 which surmounts the platform 6 at one side of the opening 102 in which the shifting-frame is mounted and is provided with slots 103 at its ends through which guide bolts 104 pass into the platform 6 and serve to guide the bar 101 in its movements. A lever 105 is fulcrumed as at 106 upon the platform at the side of the bar, and by a link 107 is connected with the bar in a loose manner. A lever 108 is pivoted as at 109 to the platform in rear of the slide-bar 101, and the rear end of said lever projects into the path of pins 110 located upon the front edge of the sliding table section at the right side of the machine, so that as the section is slid outward or inward, said pins will contact with the rear end of the lever and operate the same and inasmuch as the front end of said lever engages with the sliding bar 101 said sliding-bar will be operated in a similar manner and direction, and

thus cause the friction pulleys to be moved out of contact with the conical frictionshells 97. The outward movements of the tablesections are also limited by stop-pins 111 that extend upward from the beams 1 and frormthe under sides of the table-sections.

In bearings 112 located upon the stationary platform 6and the short transverse beams 83 there are pivoted the opposite ends of swinging strips 113 which serve to condense the lower end of the shock and prevent the same from following the movements of the tail-sections. When the machine is being operated, the hinged strips 113 lie flat upon theplatforms and hence do not offer obstructions, over which the operators would be liable to trip while placing the stalks in position thereon.. Theyare, however, as will hereinafter appear, swung to a vertical position when it isdesired to condense the bottom of the shock shape, is secured to the inner end of a horizontal arm 119, and at its terminals has perforations 120, which receive and loosely ride upon the guide-rods 117. A coiled spring 121 is secured at its upper end to the transverse cleat 116, and at its lower end to a part that moves with the horizontal arm 119,-the tendency of the spring being to normally elevate the arm. The horizontal arm is surmounted by a pair of curved arms 122 which are pivoted as at 123 at their inner ends and overlap each-other. A pivoted trigger 124 is located in a slot immediately in rear of the curved arm, and the lower end of the trigger is loosely connected with the front end of a reciprocating rod 125 whose rear end is adaptagainst the same byacoiled spring 127 coiled upon the rod 125. When not influenced by the spring but by the cam the trigger remains elevated at its upper end in rear of the crossed or overlapping inner ends of the curved arms, thus locking them in their outward position, but when the horizontal arm together with the curved armsis lowered and the rod is influenced only by the spring the said rod' is retracted and draws the trigger downward out of the path of the curved arms permitting them to fold or swing into alignment with the horizontal arm, and thusin a manner hereinafter obvious be readily disengaged or with drawn-from the shock.

This completes the construction of the ma chine, and the operation of the same is as followsThe machine is drawn along the side of a body of standing corn, the team being located at the left of the machine and connected with the draft-tongue 130. The corn is divided by the diamond-shaped frames at the center of the same and a portion deflected to each side of said frames where the stalks are gradually concentrated and severed even with the platform 6. As they are severed they are caught by the hooks of theinwardly traveling chains in the manner heretofore described and carried back through the passages 51 and 52 to the passage 53,where they are caught by the arm 54. An attendant grasps the corn by the armfnl and deposits the same against the curved arms of the shockpost around which the shock is formed, the butts of the stalks resting upon the table sections which of course are closed. When a sufficiently large shock is produced, the same is tied, and the lever 105 is swung to the left or away from the grain-side of the machine. Through the gears described motion is conveyed to the longitudinal shafts which are retated and through the medium of their gears communicate motion to the rack-bars upon the under sides of the table-sections, so as to spread or separate the same. The hinged strips are swung upward by hand so as to prevent the stalks following the movements of the table-sections, and the latter being drawn from under the lowerend of the shock, said shock is dropped solidly and squarely upon the ground so as to stand firmly. The dropping of the shock causes the horizontal arm of the shocking-post to descend against the tension of its supporting-spring so that the shockis maintainedintact until it reaches the ground. The opening or separating of the table sections is arrested by the pins 110 operating against the lever, which as before stated, causes a breaking of contact between the cone-pulley and the shell. When this has been accomplished the operator shifts the lever 105 so as to throw the opposite conepulley and shell into engagement and reverse the movements of the shafts and gearings, the machine all the While being driven along and thus the table-sections are closed or drawn inward. The descent of the horizontal arm of the shocking-post serves to unlock the curved arms of the post, and as the machine is driven ofi the curved arms yield or swing into alignment with the horizontal post and arelthus drawn readily from their engagement with the shock. In this manner the operation is continued the shocks being formed and deposited with facility and dispatch.

From the foregoing descriptionin connection with the accompanying drawings it will be seen that I have provided a machine of comparatively simple construction, that may be readily operated, and which will sever and gather the corn-stalks in a convenient manner for bundling, and which will facilitate the building of the shock and tying of the same, and finally that after such tying the movement of the machine may be utilized to drive the gearing for purpose of dumping the shock squarely upon the ground, and that an automatic disengagement of the shocking-devices will then occur.

Various changes in the details of construction will readily suggest themselves to those skilled in this class of machines, and I therefore do not limit my invention to such details as I have herein shown, but hold that I may make such variations as may suggest themselves from time to time and yet be within the scope of my invention.
