IMPROVEMENT IN PLATFORMS FOR HARVESTERS.
The Schedule referred to in these Letters Patent and making part of the lame.
To all whom 'M may concern:
Be it knownjthat I, @anrsrornnn Lrnanx, of La Fayette, in the county of Tippecanoe and State of Indiana, have invented a new and useful Improvement in Harvesters; and I do hereby declare that the followingis a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification.
Figure 1 represent-s an inverted plan view of my improved harvester.
Figures 2 and 3 are vertical transverse sec-tions of the same, taken on the plane of the lino :t a', fig. 1,
vand showing the platform'respectively extended and contracted.
Similar letters of reference indicate corresponding parts.
This invention rela-tes to grain platforms for liarvesters, and consists in certain improvements, which will be specified hereinafter.
A, in the drawing, represents the finger-bar of a harvester. It is made of.,n1etal in such form thatits cross section will be like the letter U, the clo'sed end being in front, and the face forming, respectively, the upper' and lower sides. The finger-bar may as well be made in form of a letter' L, that is to say, the. lower face plate may be lei't ofi'.
Near the ends of the finger-bar are pivoted to its lower' plate levers B B, which are laid diagonally to reach, respectively, to the diagonally-opposite ends ot'- a plate C.
'.lhe outer ends of the levers B have projecting pins n., that fit into slots b, of a rib, c, that is fastened to the under side of the plate C. One of the levers is or may be slotted near the middle, to receive a pin, d, from the other; thereby their motions are made simultaneous. The plate C is the outer one of a number th-at forms the plat-form. The other plates D of the platform rest 4each with its back portion upon the front portion of the one in itsy rear. Each has a hook, e, at each end, and a downward bent front edge, f, as shown.
The hooks e embrace the ends of the plates in rear,
back of their flanges f. rIhe several plates are .thus
pull the next in its front, and so on until the entireA platform is produced in rear of the finger-bar, as in ti gs. 1 and 2. When, however, the levers B areswung into the finger-bar, they will carry the plate C in with them, and that will, with its fla-nge f .or other similar stop, push against the flange f of the plate D, next in front, and so forth, until all the plates will be collected within the ngerbar, as in tig. 3. The levers can be swung in and ont by means of avertical crankshaft E, which is swivelled in ther inner end or shoe of the linger-bar and has its crank g fitted into the front end of lever B.
The shaft can be turned by means of a hand or footlever F.
G G, are bars pivoted under the ringer-bar, to sustain the platform, their ends abntting'in such case against stops h formed on the plate C.
The operation is as follows:
Then the platform is to remain extended for handraking, it is merely left in the position shown in gs. 1 and 2.
\Vhen, however, the gavels are to be dropped quickly as soon as cut, the driver or some other attendant will have to alternately extend and contract the platform. \Vhile it is extended, it will receive the ont grain; when contracted, it will suddenly drop it. The movement may, if desired, be made automatic.
Having thus described my invention,
I claim as new and desire to secure by Letters Iat entlevers B B, plate C I), and pivoted sustainin g bars G G, all constructed, arranged, andoperating asset forth.
2. The grain platform constructed as described, in combination with the V-shaped tiuger-bar A, as and furthe purpose specied.
