HUSK1NG-ROLL.

SPECIFICATION forming part of Letters Patent No. 613,249, dated November 1, 1898.

Application filed November 4, 1897. Serial No. 657,318. (No model.)

To all whom it may concern:

Be it known that I, Simon S. Creider, a citizen of the United States, residing at Sterling, in the county of Whiteside and State of 5 Illinois, have invented certain new and useful Improvements in Husking-Rolls, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,forming a part of this speciio fication.

My invention relates to certain new and useful improvements in husking-rolls of that general type in which rolls are employed for removing the husk from the ear.

The primary object of the invention is to provide a simple construction and arrangement of parts and combination of devices for completely and effectually removing all the husk from an ear of corn without shelling the corn or crushing or otherwise injuring the same.

Another object of the invention is to provide husking-rolls having operative surfaces graduated in hardness so as to facilitate the 25 removal of the husk and prevent shelling or inj ury to the corn.

A further object of the invention is to provide husking-rolls composed of unyielding sections and yielding sections securely held 30 in place between the unyielding sections and provided with projections seated therein and capable of moving to a limited extent in any direction.

My invention also has certain other objects 35 in view, which will be hereinafter pointed out in the detailed description and in connection with the accompanying drawings, in which—

Figure 1 is a perspective view of a pair of 40 husking-rolls embodying my invention. Fig, 2 is a longitudinal sectional view of one of said rolls. Fig. 3 is a transverse sectional view of the pair of rolls. Fig. 4 is a transverse sectional view of a modified form of one 45 of the rolls. Figs. 5, 6, and 7 are longitudinal sectional views of the rolls embodying my invention in different forms.

Referring to the drawings, in which like letters of reference denote corresponding go parts in all the figures, A designates the rolls in their finished form, which are arranged side by side, so that their peripheries are in substantial contact with each other, as shown in Fig. 1. These rolls are mounted on shafts B B, which extend entirely through the rolls 55 and are provided with intermeshing spurgears C, so that motion imparted to one of the rolls will be communicated to the other in an opposite direction. These rolls and spur-gears are preferably of equal size, so that 60 the peripheral velocity of the two rolls may be equal, and in their operation the rolls rotate in an opposite direction, so that their peripheries will approach each other, as indicated by the arrows in Fig. 1. 65

Each roll is built up of unyielding sections and yielding sections mounted and secured upon its shaft, and the operative surface of the roll is composed of alternate yielding and unyielding sections. 70

D D designate cylindrical and substantially smooth sections composed of wood or metal or other unyielding and non-gripping material whose diameter is equal to the diameter of the roll. These unyielding sections are ar- 75 ranged on the shaft and are provided with laterally-extending cores F of less diameter than the diameter of the unyielding sections proper. When these unyielding sections are arranged in place on the shaft, the cores will 86 contact with each other and thereby hold the unyielding sections rigidly in place and spaced a regular and suitable distance apart. To this end nuts b or other devices may be employed for securing the unyielding sections 85 on the shaft.

E E are cylindric sections composed of india-rubber, gutta-percha, or other yielding material, and these yielding sections are arranged on the shaft between the unyielding 90 sections, and their diameter is substantially equal to the diameter of the unyielding sections, so that the operative surface of the roll may be smooth and even. These yielding sections are preferably arranged on the cores 95 F and between the unyielding sections to completely fill the space between said unyielding sections and form therewith a smooth-surface roll.

The sections D and E maybe permanently 100 and non-rotatively secured on the shaft by keys or bolts or otherwise; but I prefer to .

613,249 make all of said sections independent of the others and removable, so that they may be readily replaced when worn or broken. The shafts B may therefore be of non-cylindric 5 cross-section and the sections D and E provided with openings corresponding thereto, in order that when the sections are arranged upon the shaft they will be held in their proper position; but it is obvious that the secio tions may be secured upon a shaft cylindric in cross-section by means of clamping devices.

The sections D and E are preferably made solid; but they may be built up of parts and T5 projections G, having bases g seated in the yielding sections, substantially as indicated in Fig. 2 and elsewhere in the drawings. The bases of these projections are preferably of greater diameter than the diameter of the 2o projections themselves, so that when the yielding material is molded around the projections they will be securely held in place. The projections are also capable of a lateral movement in every direction, and they may 25 also move in a radial line of the roll. The rolls are substantially in contact with each other, as before stated, and during their rotation toward each other the projections will embed themselves in the yielding sections, 30 the fact that the projections are supported and held entirely in the yielding sections enabling them to respond to any peculiar or unusual movement of the rolls. Both the surface of the yielding and unyielding sections 35 and the projections engage the husks while the ears of corn lie in the trough formed by the upper adjacent faces of the rolls, and the continued operation of the rolls finally remove all the husks from the ear,which gradu40 ally works down on the inclined rolls to the bottom thereof and drops off.

To facilitate the operation of husking the corn, I prefer to graduate the hardness of the engaging surfaces of the rolls so that the up45 per ends of the roll will be comparatively soft, while the lower ends are comparatively hard. If the rolls are made entirely of rubber or like yielding material, the upper portion will preferably be composed of compara50 tively soft material, the middle portion of a somewhat harder material, and the lower portion of a still harder material. This graduation in the hardness of the yielding material may be carried out when the rolls are com5 5 posed of yielding sections and unyielding sections, it being only necessary that the adhesive action of the rolls shall be greater at their upper ends than at their lower ends. By thus graduating the adhesion of the rolls 60 it will be observed that the operation of the roll will be greatly facilitated, for the reason that it is desired to have the rolls engage the husks firmly when they first enter the rolls; but as the husk is removed it is desired that 65 the rolls shall not engage the ears to injure the corn, and it will therefore be understood that as the husk is removed the ears are work ing down the length of the rolls, and by the time the husk is entirely removed the ears are on the lower ends of the rolls, which are 70 composed of the harder material, wherefore the ear of corn is moved on without injury.

In Fig. 2 I have shown by the shading of the yielding sections the graduation in the hardness thereof above referred to, the black 75 sections at the left-hand end of the roll indicating the softest section, the heavy-lined middle sections indicating somewhat harder material, and the lighter-lined sections at the right hand of the roll indicating the hardest 80 sections.

The sections E maybe secured to the cores by frictional contact or by suitable adhesive material or by screws or pins or by the engagement of tongues E in grooves F' on the 85 core F, as illustrated in Fig. 4. The yielding sections E may also be built up directly from the shaft B instead of being arranged on the cores of the unyielding sections, as shown in Fig. 5. It is also obvious that the 90 core F may be made independent from the unyielding section D, as shown in Fig. 6, or it may be attached only to one end of the section, as shown in Fig. 7, such changes and modifications in the construction and arrange- 95 ment of the core being within the purview of my invention.

I am aware that changes in the form and proportion of parts and details of construction of my invention may be made without too departing from the spirit or sacrificing the advantages thereof, and I woiild have it distinctly understood that I reserve the right to make all such changes as fairly fall within the spirit and scope of my invention. The 105 shafts B may be made hollow and other changes may be made in the construction and arrangement of parts which will not constitute a departure from my invention, but will lie within the skill and callingof those fa- no miliar with the art.
