Abstract: A hanging chute with a rib cage is described. In accordance with one embodiment of the invention, a chute constructed from flexible wear material with a rib cage to reinforce the chute. In particular, several ribs are dispersed throughout the length of the flexible sheet for support. A flexible sheet has a reinforced edge with varying thicknesses to accommodate different weight loads and abrasive conditions. Furthermore, the chute has interlocking edges for ease of constructing long lengths from a series of shorter sections. These shorter sections are easier to transport to a processing plant or other site where the chute is to be installed. Preferably the chute is easily maintainable and can incorporate wear inserts for additional wear resistance.

Abstract: The invention pertains to a sieve bed for a sifting machine, consisting of rectangular sieve elements (10), which are attached to a support frame (1) with their edges abutting each other, the support frame being provided with mushroom-shaped mounting pins (3), each of which is provided with a head which engages in an interlocking manner in corresponding recesses (11a and 11b) of the sieve elements (10). To facilitate the assembly and disassembly of the sieve elements in a sieve bed of this type and to protect the connection from premature wear the invention proposes that the receptacle (11) for the head (4) of the mounting pin (3) be closed off at the top; that the receptacle (11) for the head (4) of the mounting pin (3) be provided at the bottom with an entrance opening for the head (4) of the mounting pin (3); and that the wall of the receptacle (11) be provided with an inward-projecting bead (12), which can be snapped under the head (4) of the mounting pin (3).

Abstract: An improved sorting apparatus for sorting sand, rock, gravel and other fragmented material utilizes a wire screen panel having a plurality of sorting zones with the apertures of each zone having a different cross-sectional area. A multiplicity of equally spaced, parallel, serpentinely crimped, longitudinal wires extend from receiving end to discharge end of the panel and are rigidly retained by attachment shrouds at the ends, permitting the longitudinal wires to be tensioned and sagging of the wires avoided by gradually tightening and straightening the longitudinal wires. Mounting means is provided to mount the panel in most commercially available vibrating screen boxes and includes a stationary angle iron mountable at one end of the screen box to retain an attachment shroud at an end of the panel and further includes a plurality of clamping devices adjacent the remaining end of the screen box and engaging an attachment shroud at the remaining end of the panel.

Abstract: Integrally formed, elastomer screen units having a multiplicity of sorting apertures therein are provided for longitudinal and transverse connection in multiples to form screen bodies for sizing and sifting fragmented, hard-stock materials, each unit comprising a generally rectangular, preferably integral construction having upper and lower surfaces and first and second edges. The shaping of the first edge is preferably complemental to the shaping of the second edge and the same complemental relationship is true of the left and right lateral side edges of the unit. The units connected together in multiple are supported and mounted for hinge action on rods or stiff wires which extend transversely of the direction of flow of material along the shaker box or screen body.

Abstract: A segmented screen body or bottom for classification, screening and washing of fragmented hard stocks employs a multiplicity of segmented elements constructed of elastomer or rubber material which, when abutted and supported in predetermined relations, define sieve apertures of a predetermined size and extending, if desired, in staggered longitudinal rows. The structure further requires a multiplicity of parallel transverse metal wires or equivalent elements which are embedded and extend through appropriate apertured portions of the elastic components. In the preferred form the essential elements include T-shaped and L-shaped elements, all of which may be obtained from identical integral moldings of T-shape and many of which are cut along transverse lines at the T-top to provide from the same moldings complementary L-shaped elements.
