Abstract: A scum sweeper for sweeping surface floating matters in a clarifying tank to a collector channel. A sweeping blade is pivotally hanged by arms to parallel endless running chains mounted onto a supporting frame installed in the tank at an above position with respect to the collector channel. A motor drives the chains that haul the blade back and forth successively over and at the surface of water in the tank.

The apparatus efficiently equalizes surface pressure exerted on the tree (2) trunk, even though the drive wheel is without cushioning rubber material. The transmission means (5) arranged on the drive wheel (4) is longer than the wheel perimeter. Consequently, the transmission means is arranged to form a plane surface between the drive wheel and the tree trunk, whereby a continuous surface pressing evenly against the tree trunk is formed on the wood side in the apparatus.

Abstract: A drag conveyor consists of a uniquely-configured trough and correspondingly-shaped outer edges of chain-driven paddles which enable the trough construction to provide physical support for a return run of the chain. The cross-sectional shape of the trough further restricts the paddles from tending toward lifting above the trough bottom and climbing or twisting as they carry material toward the outlet end of the conveyor. The paddle shape results in a self-cleaning conveyor, even enabling handling of materials heretofore not feasible with conventional U-shaped trough conveyors. Elimination of obstructing idler sprockets and cross shafts of the prior art enables a productivity increase of as much as 15% for the same designated size of conveyor.

Abstract: A high-performance chain scraper conveyor is equipped with symmetrical channel belts and with a chain conveyor which can turn around corresponding axles so that in combination with the corresponding shape of the channel belts a considerably longer life and higher capacity can be achieved. The ends of the individual channel belts are equipped with overlap tongues and abutting areas across the entire width of the channel diagonally to the transport direction so that the result is an extremely quiet, highly efficient operation. The unit, therefore, is clearly more economical. Channel and herringbone chain conveyors are fully symmetrical over three axles. This means they can be turned separately or together and have at least twice the life of customary chain scraper conveyors. FIG. 3 is to be used for publication.

Abstract: Chain webs for chain conveyors, which are primarily used in underground mining and in tunnel building for the transport of large quantities of materials, consist of mutually engaging horizontal and vertical chain links in which the horizontal links of the two adjacent chains are joined by a one or two-piece bracket running across their longitudinal direction, sufficiently raised above them and having a reversible tooth shape. This results in a kind of toothed chain providing the optimum power transmission from the chain wheel to the chain web, where both chains run exactly in the middle of the belt, as is usual in double-centered chain conveyors. The special shape of the reversible teeth makes it possible to use such a chain web on both sides and to move it forwards and backwards without any risk.

Abstract: A chain conveyor for a miner in which the chain adjacent the drive sprocket is guided and supported by channels in a casting such that tension in the chain is reacted by the casting and separated from the driving force applied to the chain by the drive sprocket. The casting may be spring loaded away from the idler sprocket at the other end of the conveyor. The pitch of the sprocket teeth is preferably less than the pitch of the chain, allowing for drive sprocket build up from entrained fines.

Abstract: Conveying apparatus for use in conveying mineral ore employs a curvilinear channel section or pan which joins straight groups of similar channel sections joined end-to-end together. A scraper-chain assembly circulates along the channel sections in upper and lower runs. A unit with a hollow housing is combined with the curvilinear channel section and this unit has an upstanding hollow pillar forming a hub on which two rollers are mounted for independent rotation. The rollers are shaped to engage with the scrapers of the scraper-chain assembly to guide the latter during its passage along the curvilinear channel section. To enable the roof of the mine working to be adequately supported over the zone in which the curvilinear section and unit are installed, a roof support with alternately shiftable hydraulic props is located within the hollow hub of the unit. The props are connected to a multi-part roof bar and extend through an elongate aperture in the housing top wall.

Abstract: Corner units for automated animal feed conveyors and the like include a wheel about which a feed carrier, such as an endless chain or belt, is guided. A wear plate and wheel mounting arrangement for such corner units comprises a wear plate having a generally regular shape with a geometric center supported on the base of the unit housing adjacent the corner thereof. A spindle rotatably mounts the wheel thereon, and is attached to the wear plate at a location eccentric to the geometric center of the wear plate, whereby rotation of the wear plate about its geometric center with respect to the housing base shifts the wheel between a first position wherein a narrow feed carrier is centered in the housing and a second position wherein a wider feed carrier is centered in the housing. Fasteners rigidly attach the wear plate to the housing base in one of the positions selected in accordance with the width of the feed carrier, thereby adapting the housing for conversion to use either narrow or wide feed conveyors.

Abstract: An endless power-driven conveyor has flights in the form of rakes whose teeth extend between a plurality of parallel comb elements that extend lengthwise of the upper run of the conveyor, for example for removing solids from a liquid. Two endless conveyor chains are interconnected by crosspieces beneath the comb elements; and the rake teeth upstand from these crosspieces.

The comb elements are curved about the head wheel and received in crenelations in the head wheel, the outer surfaces of the crenelations and the outer surfaces of the comb elements about the head wheel forming a continuous partially cylindrical contour. The comb elements then diverge downwardly from the head wheel and terminate in substantially vertical downwardly directed free ends which strip the solids from the rake teeth for gravity discharge of the solids into a container.
