Harvester.
Nn.- 21,125.. Patented Aug. 10, 118.58.
UNITED STATES PATENT OFFICE.
M. E. ELLSWORTH, OF HUDSON, OHIO.'
IM PROVEM ENT IN HARVESTERS.
Specification formingpa-rt of Letters Patent No. 21,125, dated August l0, 1858.
To all whom it may concern:
Be it known that I, MAEcUsE. ELLswoE'rH, of Hudson, in the county of Summit and State of Ohio, have invented new and useful Improvements in Harvesters; and I do hereby declare that the following is a full and coniplete description of the construction and operation of the same, reference being had to the accompanying drawings, making part of this specification.
The nature of my` invention relates to the mounting of the drivers seat upon the gearplank or frame in such a manner that in raising or depressing the cutter-bar the center of gravity or' the seat is changed relatively tothe machine itself, and consequently an equilibrium is preserved, whereas in other cases, in a rigidly-attached seat, for example, as in those machines having a gear-plank, reach-board, and caster-wheel, the Weight of the driver is thrown more or less forward or backward, according as the cutter-bar is elevated or depressed.
Figure l is a side elevation of a machine with my improvement attached. Fig. 2 is an end view of the same, and Fig. 3 is a diagram representing the difference in the operation of a machine with and without my improvement.
Like letters refer to like parts.
A represents the driving-wheel.
B represents the gear-plank.
C represents the foot-board.
D represents the lever, and F represents the seat.
The foot-board C and seat F are attached to each otherin the following-named manner: The standard G is rigidly attached to the footboard O and supported by the brace H. When a long seat is used the forward end is attached to the standard G by a hii1ge-joint,and the back end is supported by a spring, I; or the standard G, brace H, and spring I may be dispensed withif the long seat is not used,
and a single standard, K, to the top of which a single seat may be attached to the arm L, used instead, and upon which the,seat L may be mounted.
The foot-board O is supported in a horizontal position by rods M and N, of proper lengths to reach the gear-plank B, the rods M being enough longer to accommodate the inclined position of the gear-plank B. These rods are attached both to the gear-plank and foot-board by iexible pin or hinge-joints M M and N N. By this means a certain amount of forward and backward movement is allowed the foot-board; but this is kept at any desired point by the rods O and P, but one of which, however, is used at one time. When the seat F is used the long rod Ois attached byahookand-eye joint to the forward end of the footboard C at C', the opposite end being secured ina similar manner to the reach-board at O. Now, if the lever D occupies the position seen in Fig. l, the gear-plank B, reach-board E, and foot-board O and seat F will also occupy the same relative position seen in Fig. 1 'but if the lever D is elevated from its position at Q to R the gear-plank, reach-board, foot-board, and seat would all be changed from their position seen at B E C F to that indicated bythe red lines in Fig. 1, representing the several positions of these parts, respectively. By this means the seat F is not only kept in nearly a horizontal position, but is brought forward, so as to preserve an equilibrium in regard to the point of gravity. It' the seat L is usedl, the
same being attached to the arm L upon the standard K, the rod O is removed andthe short rod P used instead thereof, with like results in regard to the seat L.
In case the seat is rigidly attached to the gear-plank B, the consequence resulting from an elevation or depression ofthe cutter-bar is clearly shown in the diagram, Fig. 3, in which the black lines represent the position of the machine as seen in Fig. l, the red lines showing the position of the seat and other parts, with myimprovement,the same as in Fig. l, and the dotted lines showing the position the scat and other parts would occupy with the lever raised from Q to B, with the seat rigidly attached to the gear-plank B, as in the common form of construction. The reason of this change is, that the distance between Nand Ol is less when the lever is at Q than it is when 'the lever is at B, in consequence of the increased number of degrees embraced in the angle E', the point O moving forward as the of the lever D, the back end of thefoot-board and seat are consequently elevated more than the forward end, as specified.
It will also be observed that in a certain sense this seat is self-adj usting-that is,'it preserves its equilibrium in relation to the axis of the driving-wheel, as specified.
What I claim asv my invention, and desire to secure by Letters Patent, is-
The herein-described manner of attaching the seat to the gear-plank by means of the or their equivalents, which connect the footboardv C directly with the reach-board E, all i operating in the manner and for the purpose set forth.
. M. E. ELLSWORTH.
