SNAPPlNG-ROLL FOR CORN-HUSKING MACHINES.
SPECIFICATION forming part of Letters Patent No. 778,588, d ed Decembe r 27, 1904.
Application filed March 12,1903. Serial No, 147,401.
To (tZZ whom it may concern:
Be it known that I, HENRY KoLLINe,a citizen of the United States, residing at Arlington Heights, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Snapping-Rolls for Corn-Husking Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
Myinvention relates to a novel construction in snapping-rolls for corn-husking machines, the object being to provide rolls which will take a firm hold of the cornstalks and prevent slipping and which will bite off the ears without partially shelling same; and it consists in the features of construction hereinafter fully described and claimed.
In the accompanying drawings, illustrating my invention, Figure l is a central vertical longitudinal section of snapping-rolls constructed in accordance with my invention and showing same mounted in the bearings and frame of a corn-husking machine and geared together. Fig. 2 isa transverse section, on an enlarged scale, on the line 2 2 of Fig. 1. Fig. 3 is a plan view of a part of a snapping-roll constructed in accordance with my invention.
My said snapping-rolls preferably consist of steel cylinders A, provided at their ends with trunnions I3, by means of which said rolls are journaled in bearings. Each of said rolls is provided on its periphery with parallel longitudinal rows of conical recesses C, so arranged that between the rows of recesses sharp edges D are formed, said recesses also forming parallel circumferential rows between which narrow shoulders E are left. Thelower of said rolls A is journal ed in rigid bearings F, while the upper roll is journaled in the vertically-movable bearings G, mounted in the guide-frames H and normally held at the lower limits of their movement by means of compression-springs I, the pressure of which is controlled by the hand-screws J in a wellknown manner. The trunnions B carry spurgears K at one end, by means of which said rolls are geared together, the trunnion of the lower roll also carrying a drive-pulley L.
The said rolls A are so arranged and geared together that in revolving the mouths of the recesses of one roll will always register with the mouths of the recesses of the other roll, so that said sharp edges D register and coact to cut the stems of the ears and by their pinching action on the cornstalks prevent the rolls from slipping Without pulling same through. The shoulders E and other smooth peripheral surfaces of said rolls provide such bearingsurfaces as to prevent dulling of the sharp edges D by pressure against each other.
The snapping-rolls of corn-husking machines are subjected to enormous pressure and frequently break, for the reason that the diameter of the same must be maintained as small as possible in order to prevent them from grasping the large ends of the ears and drawing same through instead of breaking them off. Owing to the irregular contour of such rolls, the same must be generally cast, and hence are brittle and unable to resist the strains.
My construction is advantageous, inasmuch as I am enabled to use steel shafting into which the recesses are drilled on an ordinary drill-press, and owing to the shape of said recesses the said shaft is only very slightly weakened, thereby enabling it to bear any strains to which it is subjected.
I claim as my invention-- 1. In a corn-husking machine, a pair of snapping-rolls, comprising two parallel cylinders geared together to revolve in unison and each provided on its periphery with longitudinally and circumferentially arranged parallel rows of conical recesses, said recesses being slightly spaced apart in their longitudinal arrangement and the edge of each recess meeting the edge of the adjacent recess in their circumferential arrangement so as to form sharp cutting edges between each two adjacent recesses.
2. In a corn-husking machine, a pair of snapping-rolls comprising two parallel cylinders geared together to revolve in unison and each provided on its periphery with longitudinally and circumferentially arranged parallel rows of conical recesses, all the recesses of all the longitudinal rows meeting at their edges all the recesses of the adjacentlon- IOO gitudinal rows so as to form sharp edges between each two adjacent recesses of the longitudinal rows, and circumferentially so arranged as to leave annular shoulders between the several circumferential rows of recesses.
3. In a corn-husking machine, a pair of snapping-rolls comprising two parallel cylinders geared together to revolve in unison and each provided on its periphery with longitudinally and circumferentially arranged parallel rows of conical recesses, said recesses being circumferentially so arranged as to form sharp edges between each two adjacent recesses of the longitudinal rows, and longitu-
