Fig. 6 is a view similar to Fig. 3 showing a modified construction; and
Fig. 7 is a View taken on line VII-VII of Fig. 6.
Referring particularly to Fig. l, it is seen that the invention may be applied to a, pair of corn harvester husking rolls rotatably supported in coacting side-by-side relation by longitudinally spaced front and rear pairs of bearing structures I and 2, respectively, and that each roll may include an inner shaft member 3 to which is removably secured a forward ear-snapping section 4, an intermediate trash-removing section 6, a rear husk-removing section 1, and a rear trash-removing part 8. The rear end portions of the inner shaft members 3 are drivingly connected by rneshed gears 9 and the end of one shaft member is provided with a suitable coupling II for connecting same with a power shaft or source (not shown). In this connection, a pair of rolls such as herein described is adapted to be utilized in a corn harvester of the type disclosed in U. S. patent, C. J. Scranton, 2,340,084, to which reference may be had for additional information as tothe general arrangement and coaction of parts.
The rear end of each trash section 6 terminates in a cylindrical portion I2 of reduced diameter provided with a pair of longitudinally extending, diametrically opposed grooves, keyways, splines or the like I3 (see Figs. 2 and 3), and the forward end of rear trash section 8 also terminates in a cylindrical portion I4 of reduced diameter provided with longitudinally extending grooves, keyways, splines or the like I6 similar in shape, num.- ber and arrangement to the grooves I3 in the opposed reduced end portion of trash section 6. The trash sections 6 and 8 are secured to the inner shaft member 3 with their grooves I3 and I6 disposed in substantial longitudinal alinement.
In this embodiment of the invention, the husking section 'I comprises front and rear parts (the rear portion of trash section 6 and the front portion of trash section 8, respectively), a relatively thin tube II surrounding the portion of shaft member 3 included between trash sections 6 and 8 and having its opposite end portions telescopingly surrounding and radially rigidly supported by the cylindrical end-portions of the front and rear parts, and a pair of internal projections, keys, or the like I8, which may be riveted or otherwise secured to or formed on each end of the tube, are slidably disposed in the diametrically opposed grooves I3k and I6 of the front and rear parts, i. e., the rear and front portions I2 and I4 of trash sections 6 and 8, respectively. And it should now be obvious that the connection between the ends of the tube and the front and rear supporting parts or elements prevents an angular movement of the tube relative to such parts and permits the ends of the tube to move longitudinally relative to the parts supporting same as the tube flexes laterally relative to its longitudinal axis. Moreover, if the tube should become worn or damaged suiciently to warrant replacing same, only the tube part need be replaced, and all that has to be done, in order to remove the tube part from the shaft member, is to remove only those other parts which are se'- cured on the shaft member outwardly of either the front or rear tube supporting part, and to then remove the appropriate tube supporting part and slide the tube longitudinally of the shaft member.
Referring also to Figs. 4 and 5, it is seen that one of the tubes ls covered with a relatively thick layer of rubber I9 and is formed of separable, interchangeable arcuate sections 2l having outwardly flanged longitudinal edges or edge portions 22 detachably united in abutting relation by means of bolts or the like 23. The bolts may be readily inserted and removed through alined, flange exposing holes or recesses 24 formed in the lay-er of rubber I9 which is preferably of a thickness approximately equal to the width ci the flanged portions 22. The other tube section is of nonsectional, uncovered construction and is provided with a longitudinal series of pairs of opposed holes 26 and with spring husking pegs 2'I which project through the holes 2E and are held in place by rubber plug-like members 23 operative to permit the pegs to recede within the holes 25 when engaged by the surface of the opposed roll. The construction and mounting of the husking pegs forms no part of this invention and if more detailed information is desired concerning this feature, reference may be had to the disclosure of C. J. Scrantons Patent Number 2,391,846, led November 6, 1943.
The ends of the sectional tube are supported on and connected with the cylindrical end portions of the front and rear tube-supporting parts in exactly the same manner as the uncovered roll, i. e., as hereinbefore described, the only difference being in the external diameter of the cylindrical portions of the front and rear tubesupporting parts which in this case differ an amount nearly equal to twice the thickness of the rubber layer I9 as is evident from a consideration of Fig. 4. And it should now also be obvious that in addition to preventing an overstressing of the connections between the ends of the tubes and the parts supporting same, the connections just referred to permit one or more of the rubber covered tube sections to be readily removed without disturbing the front and rear tube-supporting parts or any other parts of the roll assembly, simply by removing the readily accessible bolts 23.
Referring now to the modified construction shown in Figs. 6 and '7 in which like numerals are used to designate the same or corresponding parts, it is seen that the ends of tube I1 may be connected with front and rear parts or elements secured to shaft member 3 for rotation therewith by providing the plane annular end surface of each of such parts (the connections between the front and rear parts are identical and therefore only the connection between the front part, trash section 6, is shown) with a pair of vdiametrically alined slots 29, and by providing each end of tube I'I with a radially flanged annular plug member 3i having an exterior end surface which is coextensive with and abuts the end surface of the opposed section or part and which presents a pair of diametrically alined projections or ribs 32 slidably disposed within the slots 29. The plug members 3I may be inserted in the en ds of an integral tube and secured therein by a pressed fit or otherwise to prevent an angular movement of the tube relative to the plug members, and if seguace? g5 :the tubesis formedffnfi:separablev'sectionsaasilindicated in Figs. 2, 4 and 5, the endsibf--theisec tions .should be; clamped:l aroundtheip'lugsnby the .actionfofbolts .unitn-sufficient lforce'ltot prevent .af relative `angular@movemenimnfxthe tube :and J plugs eitherv with tore-Without thexaid Y:of interen- 'gaged projections inotfshown) .-.-Bothf fof rthe':constructionsr herein". shownand .described aiiord. a relatively finexpensilve,.I rugged 'shaftfmemberceuclosect thereby; means mounting --saiditubein spacdzsconcentricr:relationifwithf refspect. to..said portion. vof..1the-lslf1aft member `comeprisingtvannular;,plug .members mounted on'l said :shaftim'ember :for movement; axially thereofl and affordinga radially rigid support for-the opposite :ends zofxlsaidtube,.;.said: plugmembers 1 and? lthe opposed ends of said parts having portions Ytliere- -of::nonrotatably :detachably engaged :forf relative .constructionin that. no fpartmffthehusking .roll 10 eaxialzzmovement sonas to permitrthe ends-0f. said f. assembly is Asecured to shaftmemben 3sat alpoint remote from .the -rear'bearing structure therefor .byy a 1connection requiring. a hole,ikeyway.or,other :opening in or.Y through Itl'1efslf1aft,Whichwveakens -ltuberto move :longitudinally `relative 'to said' parts .andiishaftt-:member asthenltube" flexes :laterally vrelative to "its longitudinal axis said? ftube lbeing .formedzofr complementary rubber `covered arcuate zsame, and .inlthatrthe .-endsfofl tlle--tu-bel parts-,of ':15 ...s-gctions; havngyoutwaymy aangeda:longitudinm t-he' husking Vroll are :substantially .tree to'.A move longitudinallyr relative; vto 'wither frontrffand frear shaft,-.carriedy tube-supp orting rparts vas lthe .tubes Viiex` .laterally rrelativettotheir longitudina1..axes.
