Patent number: 6041916Abstract: A roll, along with methods of fabricating and using such roll, for driving a woven-wire conveyor belt, provide substantially-uniform drive across belt width, avoid disruption of belt drive, provide unidirection tracking of such belt, and avoid disruption of conveyed product during treatment of conveyed product at temperatures other than ambient. During conveyance of product for heating or cooling treatment, woven-wire conveyor belts and rolls driving such belts are often at differing temperatures, especially during start-up and shutdown of operations. Such temperature differentials can cause dimensional changes in a belt which change the relative location of belt recesses with respect to the roll surface. Selective shaping and dimensioning of roll protrusions from the widthwise center of a roll toward each lateral end of the roll eliminates mismatching of belt recesses due to changes in belt width during product processing at temperatures other than ambient.Type: GrantFiled: July 14, 1998Date of Patent: March 28, 2000Assignee: Maryland Wire Belts, Inc.Inventors: Ronald G.

Patent number: 5558208Abstract: A spiral overlay having multiple variations, but generically, comprised of wire spirals intermeshed together by connecting rods extending across the conveyor in the transverse direction. Broadly, a first overlay is made up of spirals which may be tapered and afford pitch control by incorporating elongated loops in the spirals to limit the movement of the rods therein. The elongated loops also provide for collapsibility of the spirals relative to one another. A second overlay is made of integral or modular spirals such that the overlay includes upstanding spiral elements on its conveying surface to provide traction and separation of the articles being conveyed.Type: GrantFiled: May 4, 1995Date of Patent: September 24, 1996Assignee: Ashworth Brothers, Inc.Inventor: John G. Kucharski

Patent number: 5404998Abstract: A wire conveyor belt includes a plurality of interlocked wire elements having closed ends. The interlocked wire elements have U-shaped regions which are interlocked with corresponding U-shaped regions of adjacent wire elements to form the conveyor belt. The closed end regions are formed after the wire elements have been interlocked. Each closed end region is formed by bending the end of each wire element around the adjacent interlocked wire element so that the end is adjacent to and overlapping the wire element forming a region having a substantially triangular, circular, or square shape. Each closed end region forms a space which is less than the diameter of each wire element for preventing other portions of the wire conveyor belt or other wire conveyor belts from catching on the closed end regions. A method of making such a wire conveyor belt requires first interlocking the wire elements and subsequently forming the closed end regions.Type: GrantFiled: January 3, 1994Date of Patent: April 11, 1995Assignee: Wire Belt Company of AmericaInventor: Donald J.

Patent number: 5375695Abstract: Fabricating method for an elongated woven-wire belt for direct-contact dynamic-frictional-drive along an inner perimeter lateral edge portion when the belt is moving in a path which is curved in a lateral direction with respect to its lengthwise direction. A curved path structure for support of such belt is disclosed along with methods of assembly and operation of curved path support structures. Lengthwise collection and extension uniformly across the width of the woven-wire belt is provided, along with selection of direction of movement providing for reversing direction of movement without requiring modification of the belt structure or curved path support structure. Provision is made for selectively controlling rates of movement of the woven-wire belt in a curved path support structure and for controlling rate of movement of the belt when exterior to a multi-layer curved-path tower structure.Type: GrantFiled: May 5, 1993Date of Patent: December 27, 1994Assignee: Maryland Wire Belts, Inc.Inventors: Ronald G. Daringer, Stephen D. Wilcox

Patent number: 5363952Abstract: In a materials treating furnace, a belt is provided for transporting articles to be treated through a high temperature treatment zone. The belt comprises a succession of interwoven links, each of which is made up of a length of tungsten wire which has been heated and wound around an elliptical mandrel to provide a link which is in the form of a slightly flattened helix having no sharp bends. The interweaving of the helical links provides a large number of interlocking contact points between successive links.Type: GrantFiled: September 10, 1993Date of Patent: November 15, 1994Assignee: Centorr/Vacuum Industries, Inc.Inventors: Charles W. Miller, Jr., John Currier, Larry Duclos, Thomas Ayer

Patent number: 5358095Abstract: A removable conveyor flight formed of a flight body 12 having downwardly extending arcuate clamp arms. A pair of opposing arcuately shaped rigid clamps (14) and (16) are embedded within the flight body. Formed integrally with clamps (14) and (16) are compression tabs (20) which extend upward into the flight body to a fulcrum point (22). Bolts (28) are provided to draw the clamps together, thereby clamping the resilient clamp arms of flight body (12) against the cross bar or rod (34) of draper chain (32).Type: GrantFiled: August 23, 1993Date of Patent: October 25, 1994Inventor: Robert B. Curl

Patent number: 5265715Abstract: A belt includes a plurality of rows of endless chains and can body conveying sections each defined between adjacent ones of the chains. Each of the endless chains are formed includes a plurality of U-shaped unit members each having a bottom fitted in an open end portion of a preceding one in the row, the engaged portions of the preceding and succeeding unit members being connected together by a plurality of rotatable connecting rods common to the chains. Intermediate rods having a length a little greater than the can body diameter are each provided between adjacent ones of the rods of the chains and also being opposed unit members of adjacent chains. The intermediate rods are disposed at a common elevation as the connecting rods beneath the top of the chains. Thus, the conveyer belt can convey can bodies in a plurality of rows in which the can bodies will not touch each other at the open ends of these can bodies.Type: GrantFiled: October 20, 1992Date of Patent: November 30, 1993Assignee: Daiwa Can CompanyInventors: Takayuki Yoshimura, Yoshiteru Kondo, Kiyoaki Inoue, Yoshimasa Matsumura

Patent number: 5176249Abstract: Wire stock for connecting rods is run through the nip of a pair of obliquely toothed rolls having teeth which taper from one face of the roll towards the other, and have a larger radius at the tip than along the portions flanking the tip. The angle of obliqueness matches the angle that a turn of a spiral wire will traverse the connecting rod. Round wire stock for the single-faceted spiral wires is run through the nip of a pair of rolls one of which has a cylindrical surface (i.e., a flat longitudinal profile), and the other of which has a circumferential groove with a slightly larger diameter than the round wire stock. As the wire is flattened on one side, its curved side is broadened. As the resultingly single-faceted round wire is wound into flattened spiral form, it is spatially orientationally guided, so that the facet becomes located facing outwards.Type: GrantFiled: February 8, 1991Date of Patent: January 5, 1993Assignee: The Cambridge Wire Cloth CompanyInventors: Christopher D. Esterson, Conroy R. Marth, Peter K. Bailey, John D. Carduff

Patent number: 5160020Abstract: In one embodiment, the invention comprises at least one roller with a plurality of recesses in its peripheral surface, mounted on the drive and trailing assemblies of a conveyor system. The recesses of each roller are angularly disposed relative to the central axes of their respective drive or trailing assemblies and are sized to receive a portion of an endless conveyor belt contacting the rollers. The bottom and size walls of the recesses act against the engaged portion of the belt to propel the belt through the system, support the belt and maintain the belt in proper tracking alignment. The recesses are preferably distributed in circumferential rows about the periphery of the roller and, in multi-row rollers, in a parallel relation across the width of the roller. A method for estimating the optimum size and configuration of the rollers of the invention for helical woven wire endless belts is also provided.Type: GrantFiled: November 9, 1990Date of Patent: November 3, 1992Assignee: Lindberg CorporationInventor: James A.
