Abstract:
An endless conveyor chain with a plurality of permanently secured links and rods, a plurality of replaceable links and rods secured together by snap ring means, and a plurality of links and rods provided with push bar members thereon, all of said rods having enlarged diameter portions for contact by a drive sprocket.
Abstract:
An idler member is provided for use in changing the direction of travel of a moving web. The member has a cylindrical exterior surface which is adapted to be engaged by the moving web. A portion of the said exterior surface has fused thereto material deposits which are adapted to increase the frictional engagement between the idler member and the web.
Abstract:
An elastomer-covered conveyor belt employing a belting fabric having warps of metallic cables which are maintained coplanar, parallel and linear to equalize stress distribution therein and to insure that the belt will track truly. Selectively inwardly crimped, nonmetallic wefts are employed in respective layers above and below the warps in order to maintain the warps in proper positions relative to one another and to impart a desired degree of transverse stiffness to the fabric. The inward crimping of the wefts is achieved by positioning a plurality of nonmetallic binders between the warps in each pair of adjacent warps and selectively interlacing the binders with the upper and lower wefts. The binders between adjacent warps cross one another and form intersection points which abut against the warps and assist in maintaining the warps in proper position relative to one another. The belting fabric is preferably dipped in a resorcinol formaldehyde latex solution after weaving and then heat treated to remove the volatile components of such solution and shrink the nonmetallic weft and binder strands therein. The foregoing abstract is neither intended to define the invention disclosed in this specification, nor is it intended to be limiting as to the scope of the invention in any way.
Abstract:
System for the production of steel-wire-reinforced flexible belts consisting at least of an elastomeric or synthetic-resin upper layer, a core in which the steel strands are embedded and a lower layer of such material bonded into a unitary laminate while the reinforcing strands are tensioned; the invention resides in the use of an equalizing press adapted to bond the core to the steel strands prior to the application of the upper and lower layers and the final laminating phase. A supply means for each of the outer layers is provided downstream of the equalizing press and the layer is, in turn, downstream of a further supply system adapted to sandwich the generally planar array of longitudinally extending tension steel strands between layers of the core material.
Abstract:
In the illustrative embodiments of the invention described herein, a drive chain comprises at least two chains arranged in superposed interlocking relationship. Each chain comprises a succession of links with the overlapping portions of adjacent links connected together by pin members. The links of each chain further include bearing surfaces and when the two chains are arranged in interlocking relationship, the overlapping portions of the links in one chain engage the bearing surfaces of the links composing the other chain. To drive or guide the drive chain, a sprocket having a pitch equal to one-half the distance between the overlapping portions of adjacent links is provided.
