SNAP?I1\TG ROLLS FOR- HUSKING MACHINES.
Application filed December 29, 1923. Serial No. 683,457.
To all whom it may concern:
' Be it known that we, MICHAEL J. GEE- HAnnT, LoUis S; SMITH, and :h/TATHIAS S. Sirrrn, citizens of the 'United States, residing at Howard Lake, in the county of TV right and State of Minnesota, have invented certain new and useful Improvements in Snapping Rolls for Husking Ma chines, of which the followingis a specification, reference being had to the accom-' panying drawings.
This invention relates to machines for husking corn and has for its object the provision of novel rolls for snapping the ears from the corn stalks regardless of the condition of the stalks, the action being positive whether the stalks are green and moist or dry and hard.
- An important and more specific object is the provision of co-acting rolls equipped with detachable blades which may be removed and sharpened when necessary and replaced when excessively worn or broken so that the rolls may be made to last indefinitely, the construction being furthermore such that there is an interlitting relation, the blades on the co-acting rolls being what might be described as staggered and the blades of each roll being received within grooves in the other.
i-in additional object is the provision o1 rolls of this character which will be simple and inexpensive in manufacture, which will greatly increase the efficiency of the husking machine equipped therewith, and which will. consequently effect a saving in time and labor.
With the above and other objects and advantages in View, the invention consists in the combination and arrangement of the several parts to be hereinafter more fully described and claimed and illustrated in the accompanying drawings in which:
Figure 1 is an elevation of a pair of rolls constructed in accordance with the present invention.
Figure 2 is a cross section therethrough.
Referring more particularly to the drawings, we have shown a pair of rolls 10 which are identical in construction and which. may be of any desired length and proper diameter, depending upon the type of husking machine in which they are used. Each roll consists of a body 11 formed at its ends *ith reduced extensions 12 which provide means for mounting. The rolls are intergeared by means of the usual pinions 13 which are mounted on the extensions at one end.
Each roll-is "formed with a plurality of longitudinally extending grooves 14 which are relatively deep and which define shoulders 15 and 16. Disposed within these grooves against the shoulders 16 are blades 17 which project slightly beyond the periphery of the body and which have their projecting edges 18 beveled off. Disposed within the grooves are clamping strips or bars 19 which abut against the shoulders 15 and which bear upon the blades 17. The holding means consists of a suitable number of studs 20 which pass through holes in the strips 19 and which are screwed into threaded sockets 21 in the body. The heads of the studs are counter-sunk, as clearly disclosed so as not to project beyond the periphery of the roll.
It is intended that the rolls be arranged with. the blades of one in staggered relation or in alternation with respect to the blades of the other to insure an interfitting relation. Each roll has its periphery formed with longitudinal grooves 22 which will. come opposite the projecting edges of the blades as the rolls turn. I These grooves are illustrated as define-d by beveling oii the corners of the shoulders 15 and the adjacent edges of the strips or bars 19. Between the successive grooves 14, each roll has its periphery formed with other grooves 23 which assist in the proper operation.
In the use of the rolls, it is apparent that they will take all stalks whether they be dry and hard or damp, green and soft, there being no possibility of clogging under either condition. It is well known that the common snapping rolls on corn husking machines are provided only with grooves,
the edges of which wear and become dull in a short time so that they fail to pull the corn stalks and snap the ears. The well known disadvantages are not present when our improved rolls are employed and actual experience has demonstrated that these rolls are capable of doubling the output of a husking machine. Owing to the fact that the blades are removable it is apparent that they may be sharpened quickly and easily as often as necessary and may be replaced at small cost when they become excessively study of the drawings it will be apparent that we have thus provided a most efficient snapping roll structure which will be advantageous not only in the above pointed respects but which will also be a protection to operators inasmuch as the clog-proof nature of the rolls will render unnecessary the dangerous practice of putting the hands into the machine to break up a jam.
WVhile we have shown and described the preferred embodiment of our invention, it is of course to be understood that we re-- serve the right to make such changes in the form, construction and arrangement or parts as will not depart from the spirit of the invention or the scope of thesubjoined claims.
We claim:
1. A pair of revoluble snapping rolls each including an. elongated cylindrical body formed with a series of longitudinal grooves having side walls defining abutment shoulders, a blade disposed against one shoulder of each groove, clamping strips positioned within said grooves and abutting against the other shoulders and against the blades, the inner faces of the clamping strips being curved transversely to extend from the last mentioned shoulders to the blades in diverging relation to the bottoms of the grooves, and means for drawing said strips into the grooves and retaining the strips in tight clamping relation to the blades.
2. A. pair of revoluble snapping rolls each including an elongated cylindrical body formed with a series of longitudinal grooves having side walls defining abutment shoulders, a blade positioned against one shoulder of each groove, clamping strips positioned within said grooves and having their sides abutting against the other shoulders and against the'blades, the inner :faces of the strips being curved transversely and extending towards the blades in diverging relation to the bottoms of the grooves, and fastener screws passing through the strips and having their inner ends screwed into threaded sockets formed in said body and their outer ends provided with heads countersunk in the strips, said screws being adapted to draw the strips inwardly into tight clamping engagement with the blades.
In testimony whereof we hereunto atliX our signatures.
