f2 and three iden-tical idler roll `element e assemblies or units 114, AII5 and IIB lthat-are `carried through thehousings I2 and "I'3fupon the main frameor chair iII.
Main frame lor chair fl I -includes a basemember I-lof inverted V-shaped cross section, the outer end .portions I8 of which are bentto extend outwardly and upwardly .from Vthe `central portion `I'S'I yto provide .a symmetrical `base. Extending upwardly, Vone from each `of the outer ends ofthe central lportion I9 of the -base `member Il, chair Iliincludes two brackets or legs 20 and at each of the outermost ends of the sections I8-it includesa'bracket or leg 2| that eX- tends upwardly and inwardly. Brackets and `legs 20 andZ-I'Aare identical and each is welded at its bottom to v'therbase member I'I. The ytop of each'bracket-orrleg 20 and 2| #is slotted vertically=toprovide a-yoke122 (gsee Fig. `2) that receives-one loftlfieghousings I2 or I3.
Housings `I2 and I3 vare castings provided with U-shapedxgrooves or channels 23 in their outsidesurfaces that interfit slidably with the yokes 22 of brackets orlegs 20 or '2| and they are shaped to cooperate with the yokes 22 Vto pre- Vventl lateral 4,shifting 'and rotation of the housbearing .rece ,cooperate to provide self-aligning mounting features `i'or the bearing "30. Chamber "24 cooperates with the resilient orfcushion bearlnghsupport 26 and thebearing 30 to 'forms a reservoir fcrlubricant for'the bearingy y v Eachpf the centen bearingv housings t2 includes two spaced machined;oylindricalportions 3l .and 32, the axes of `whichintersect,and are parallel tothe portions I8 and I9,respect ively,vof main frame. .or chair l I I, and yeachcf these f cylindrical portions I .and `3,2j receives ,a resilientfor cushion bearing f Support t 2 6 for one of 1 the anti-friction bearings 1 30 that I support adjacent l ends of Troll .assemblies '.4 .and l5 or I I5 and Je. 1 The 595mmdrical portionss I and-elect housing- I are specerieeert letereIlY tifo .provide .aree es between 3 them that functions when the resilient or cushion bearing supports 26 and bearings 35 are mounted in the cylindrical portions 3l and 32 to form a chamber or compartment for lubricant for the bearings.
Each idler roll assembly or unit I4, I5 and I5 includes a pair of identical metal end disc members 34 provided with peripheral tires 35 of rubber or material having like resilient characteristics. The outside of each disc member 34 is recessed centrally to provide a well having a tapered cylindrical outer wall 36 that nts over a collar of one of the cylindrical portions 25', 3l or32 ofahousing I2 or I3.
Centrally or upon its axis of rotation disc member 34 is bored axially and at its outside and at the center of the recessed orwell portion thereof there is a laterally extending integral collar, boss or hollow stub shaft 3'I that-extends into the inner race of one of the bearings 3!) and is supported thereby. Opposite the boss 3l the disc 34 includes a second laterally extending integral collar, fboss or hollow stub 38 that receives a center or tubular hub member 39 that functions Yto space the opposite end discs 34 and to carry a plurality of resilient idler roll elements, discs or wheels 46 placed thereon in side by side relation. A rod 4I provided with nuts upon its opposite ends extends axially through the end discs 34 and central or tubular member 39 and clamps the elements of the resilient idler roll assembly or unit together.
Roll assemblies or units I4, I5 and I6 of idler roll assembly i3 carry and trough the working run of the belt, indicated in dot-dash lines in Fig. 1 of the drawings, of an endless belt conveyer and in practice a plurality of idler roll Yassemblies I0 are positioned to carry that portion of the working run of the conveyer where material is loaded or spilled upon it. It may be mentioned that the working run of the conveyer belt is normally troughed to such shape that its under side does `not normally ride upon the tires 35 of the adjacent end discs 34 of roll assemblies I4 are provided with the resilient tires 35 only to arrest and prevent excessive distortion of the conveyer belt thereabove as a result of overloading Each of the resilient idler roll elements, discs or wheels 40 includes a center mounting or hub sleeve 42 that ts tightly upon the center or tubuper square inch of area than others.
,and I5, and I5 and I6 and that the end discs 34 lar hub member 3S, and surrounding and preferably vulcanized to the sleeve 42 is a disc or cen `tral portion 43 made of resilient material, such,
it a rim, ring or tire 44 that is substantially nondeformable. As indicated in Fig. 1 of the drawings, rim, ring or tire 44 is T-shaped in cross section with the leg of the T imbedded in the resilient disc or central portion 43. Rim or ring 44 and the central rim mounting resilient disc 43 are preferably vulcanized together.
The disc or central portion 43 of each roll element 40 is so shaped cross sectionally, as seen in Fig. 1 of the drawings, that it includes a portion having substantially equal circumferential cross sectional areas at any of successive cross sections taken therethrough circularly or concentrically with the rim, ring or tire 44 or the axis of rotation of the portion 43. This portion of substantially equal circumferential cross sectional areas is defined generally by the radially innermost edges of the laterally flared or rim portion of resilient disc 43 adjacent the center leg of the T-shaped rim, ring or tire 44 and the outside circumferential surface of the center mounting sleeve 42 to which the resilient disc or rim mounting member 43 is vulcanized.
In Figs. 1 and 3 of the drawings there is indicated by the dot-dashlines A, B and C three of such circumferential cross sections above referred to and the equal circumferential areas mentioned are determined by calculating the circumferential areas of the disc 43 of resilient material where it is cut by the section lines A, B and C, that is, the circumferential area of disc 43 at section A substantially equals the circumferential areas of disc 43 at sections B and C.
It is important to note that by the construction herein disclosed, the resilient roll elements, discs or wheels 43 include a mounting means for `a substantially non-deformable ring, rim or tire that possesses substantially uniform elastic characteristics particularly to radial distortion produced therein when the rim, ring or tire is displaced axially or radially with respect to the mounting means for the central disc 43 of resilient material.
In known constructions of resilient conveyer discs the material at the periphery thereof and adjacent the point of impact or load may tend to dent or flatten adjacent said point of contact or certain circumferential cross sectional areas of the disc may be required to support more load With the construction disclosed herein the load supported upon the periphery of the disc or wheel 40 tends to displace the entire peripheral surface including the substantially non-deformable tire 44 with respect to the axis of rotation of the disc or wheel 40, and the load that is tending to displace the outer peripheral surface or rim of the disc 43 is distributed substantially equally throughout that portion of it where the successive circumferential cross sectional areas are equal.
Each of the rolls I4, I5 and I6 includes three of the disc or wheel elements 40, and in considering the rolls I4, I5 and I6 it is to be noted that each of them includes a hub portion comprised of the central portions of the spaced end discs, the center or tubular hub member 39 and the tubular hub sleeves 42 of the resilient roll elements, discs or wheels 40 and they each include three rim portions each of which is carried by a disc portion of resilient material between the rim portion and hub portion of the roll. Each of the rim portions of the Wheels 40 may be considered as being the radially outermost portion of it that is ared laterally to accommodate the tire 44. Each of the disc portions of resilient material increases in its axial dimension or thickness from this outer radial rim portion of the wheel 40 to the inner radial portion thereof which is adjacent the tubular hub sleeve 42 of the hub portion of the idler and this increase in the axial dimension of the resilient disc is such that successive circumferential cross sectional areas of the disc between the radially outermost rim portion and the hub portion are substantially equal. Because of the increase in the axial dimension of the disc of resilient material sothat successive circumferential cross sectional areas of it are substantially equal any load supported upon the rim portion of each of the discs or Wheels 40 Will be distributed equally throughout the resilient disc, that is, the load carried per square inch of area at any of the circumferential cross sectional areas will be subl stantiallyequal because the areas of each of the circumferential cross sectional areas are substantially equal.
It is also important to note that because the bearings 30 are supported through resilient rings or cushions 26 and because the idler roll assemblies or units I4, I5 and I6 are resilient in themselves, the bearings 30 are cushioned against shock resulting from large pieces of material falling upon the conveyer or riding over the roll units -40 thereon, thereby substantially eliminating Brinelling eiect upon the bearing parts. y f Obviously those skilled in the art may make various changes in the details and arrangement of parts Without departing from the spirit and scope of the invention as ydefined by the claims hereto appended, and applicant therefore wishes not to be restricted to the precise construction i herein disclosed.
