  • Patent number: 7665252
    Abstract: A wall bracing apparatus for mounting between a wall and the floor during construction. The wall bracing apparatus includes a tube that is mounted to a wall-mounted device and a floor-mounted device. The wall-mounted device has a backing plate and a front plate on opposite sides of the wall. A t-bar having a head at one end and a shaft through which a hole is formed extends through aligned central apertures in the plates and a wedge is inserted in the hole near the front plate end of the t-bar. A pair of ears on the front plate has aligned holes through which a pin extends that is also inserted through the tube. A duplicate of the front plate can be mounted to the floor and the opposite end of the tube can pivotably mount to the ears thereof.

  • Publication number: 20090194565
    Abstract: An improved wet cement dispensing apparatus having a tilting hopper and a hinged, angled auger tube for aiding in the cleaning of the apparatus and for delivering grout to elevated and hard to reach locations. The hopper can be locked in a first position for dispensing grout and in a tilted position for cleaning. The hopper rotates about a vertical axis. The dispensing end of the auger tube preferably extends to near the top edge of the hopper.

  • Patent number: 7165877
    Abstract: The invention is an apparatus for mixing fluent material. A hopper is pivotably mounted to a frame on a pivot axis that is substantially spaced from the axis of rotation of a mixing paddle. Because the pivot axis is substantially spaced from the axis of rotation, the mixer can be loaded by the operator at a low charge height and subsequently dumped at a higher dump height. Horizontally adjustable arms in combination with vertically adjustable legs provide for adjustability in length, width and height of the apparatus for stability when the hopper is fully dumped.

  • Patent number: 7152762
    Abstract: A control valve for controlling the flow of fluent material from a machine, the machine having a frame including a hopper and a tube mounted to the hopper, an auger within the tube and a hose mounted to the tube. The control valve has a clamp, which has a first arm mounted to the frame on a first side of the hose and a second arm mounted to the frame on an opposite side of the hose. The first arm is movably mounted to the frame in a direction toward the hose. A prime mover is drivingly linked to the first arm and the frame for displacing the first arm toward the hose, thereby clamping the hose between the first and second arms for restricting the flow of fluent material through the hose.

  • Patent number: 6499718
    Abstract: A fluent material containing and dispensing apparatus including a hopper having four sidewalls. A tube mounts to one of the sidewalls, and an auger extends from one end of the tube to the opposite end of the hopper, driving material in the hopper through the tube when the auger is rotated. A flexible hose is mounted to the underside of the tube and material in the tube pours into the hose, which can be kinked to slow or stop flow of material. A gap is formed between the outer surfaces of the auger and the tube wall. A radially inwardly extending flange can be mounted to the tube wall to slow the flow of material through the gap. Alternatively, a compressible sleeve can be mounted in the gap between the outer surfaces of the auger and the tube wall extending a substantial length of the tube.

  • Patent number: RE39639
    Abstract: A grout hopper and dispenser which may be raised on a fork lift so that grout may be placed in a concrete block wall. The grout hopper and dispenser includes an auger in the bottom thereof which forces the grout out through a tube which is connected to a flexible tube which is used by the workman in directing the grout to the appropriate location. The auger may be remotely controlled by the operator of the forklift truck which has lifted the grout hopper and dispenser into position.
