Abstract: A stone metering system for a railroad track maintenance vehicle providing improved accuracy in stone delivery. The system includes a surge hopper, a number of metering augers, and a corresponding number of splitters. The metering augers convey ballast stones from the surge hopper to the corresponding splitters, which divide the stones evenly between a number of blow tubes. The pitch of the auger screw flights is increased from the inlet end of the screw to "expand" the stone and reduce the production of fines. In addition, the diameter of the final screw flight is reduced at the outlet end of the auger to provide a consistent and even flow of stone into the splitters. The splitters are dynamically adjustable to provide even distribution between the blow tubes regardless of the cant to the rails. The desired amount of stone is delivered to the tubes by rotating the auger screw the number of full or partial revolutions associated with the amount. In an alternative embodiment, each of the metering augers is replaced by a conveyor having a belt divided into a series of uniformly sized compartments each conveying the same quantity of stone. The desired amount of stone is delivered to the tubes by driving the belt so that a desired number of compartments are emptied into the splitter.

Abstract: A conveyor for particulate matter is provided with a channel extension movable between a use position aligned with the channel and a non-use position displaced relative to the channel. The extension includes an angled edge which cooperates with the auger flighting to shear material as it leaves the extension to break apart lumps which form in the material and provide an even flow of material from the conveyor.

Abstract: A hollow shaft of a screw conveyor for transporting powder material receives pressurized air in its interior. A plurality of openings through the wall of the hollow shall permits the pressurized air to exit energetically to prevent build-up of the powder material on the inside wall of the casing of the screw conveyor. In one embodiment, the openings are slits angled with respect to the axis of the screw conveyor at about the same angle as the helical blade. This produces a swirling flow of air which, in addition to preventing build-up of materials, enhances the advance of the powder material and, when the powder material is a mixture of different materials, helps prevent separation of the materials during transport.

Abstract: Screw conveyor apparatus fabricated from integrally molded plastic modules is disclosed. The apparatus includes a multiplicity of modules axially aligned and joined or bonded so as to provide a unitary plastic screw conveyor of a desired length. A plastic axial member extending the length of the screw conveyor and which defines an elongated aperture of a non-circular cross-section is formed by joining or bonding the individual modules. In addition, each of the modules include a flight member which individually helically encircle not more than 360.degree., but when bonded together result in an overall flight member encircling more than 360.degree. and which extends the length of the joined or bonded modules. The plastic screw conveyor is driven by a drive shaft which has a non-circular cross-section and which is inserted through and cooperates with the non-circular aperture extending the length of the joined axial members. A drive or power source is connected to the drive shaft for rotating the apparatus.

Abstract: An apparatus for displacing material includes a transport thread composed of a central thread spiral and an outer thread. The outer thread spiral is fixed to one of the radially directed defining surfaces of the central thread spiral. The central thread spiral is dimensioned so as, without permanent deformation, to absorb at least the major portion of the mechanical forces occurring in the axial and radial direction of the transport thread. The outer thread spiral has an outer surface which faces away from the geometric centre axis of the transport thread and is of shorter extent in the axial direction of the transport thread and is located more distally from the center axis than the outer surface of the central thread spiral. By regulating the extent in the axial direction of the transport thread of the surface of the outer thread spiral turned to face the substrate, the abutment pressure of the transport thread will be adapted to the substrate in relation to the properties of the material being displaced.

Abstract: An auger assembled from a plurality of auger segments each of which includes a central longitudinal hollow hub with a longitudinal extension at each end of the hub. A section of helical flighting winds about the hub extending from the extension at one end of the hub to the extension at the other end. The end portions of the helical flighting are beveled to provide an acute edge and a supplementary obtuse edge of the flighting at each end portion. The auger segments have end-for-end symmetry and a plurality of segments are assembled in an end-to-end relationship about a main drive shaft to comprise the auger. When assembled to form the auger, the beveled end portions of adjacent segments overlap in a matching relationship to create a substantially smooth continuous helical flighting surface over the length of the auger. Similarly, the longitudinal extensions of adjacent augers join to create a substantially continuous outer periphery of the assembled hubs. The auger segments are made of an inert material, such as polyethylene, for use in conveying abrasive and corrosive materials.

Abstract: An auger for bulk material compressors of the type having a feed chamber and a packing chamber to which is attached a tubular silo bag. The auger includes an inlet portion, located within the feed chamber, and an outlet portion, located within the packing chamber. The inlet portion includes a shaft and flights, each preferably of constant diameter. The outlet portion also has flights preferably of uniform diameter and a shaft which is cone-shaped, increasing in diameter from its connection with the shaft of the inlet portion, adjacent the beginning of the packing chamber, to the end of the auger flights, within the packing chamber, for gradual compression of bulk material within the packing chamber. The terminal most end of the auger, within the packing chamber, is provided with an end member to provide a large surface area as a support bearing for the auger in its engagement with the compressed material without substantial lengthening of the shaft.

Abstract: A mold and process for integrally forming a modular helical shaped device such as a screw conveyor is disclosed. The mold has a center operating axis (26) and includes a first section (20A) which forms a portion of the axial member (33). The first section (20A) also forms one of the helical surfaces (36A) disposed around the center axis (26) which has an amount of rotation no greater than 360 degrees. In a similar manner, a second section (20B) is adapted for reciprocating movement along the center axis (26) between an open and closed position with respect to section (20A). The second section (20B) forms the other one of the helical shaped flight members (41). Thus, the two mold sections define a substantially enclosed cavity having an elongated axial portion and a helical shaped flight portion with a selected cross-section that forms the helical shaped device. In a preferred embodiment, there is also included a center rod member (62) which is coaxial with the axial cavity (34A) and operates so that when withdrawn from the cavity it provides an aperture in the resulting axial member (33) of the helical shaped device. In addition, the mold and technique may be used to form helical shaped devices having more than one flight member so long as each flight member does not overlap another flight member.
