  • Patent number: 4303107
    Abstract: A device for holding the weft yarn outside of a pair of takeoff rolls after there has been a filling break or upon starting up of the loom. The takeoff rolls in normal operation withdraw a measured length of yarn from a supply package and feed the yarn to a storage device such as a suction tube. The rapier on its filling stroke withdraws the measured length of yarn from the storage tube on each stroke of filling insertion. As the rapier approaches the end of the stroke, the takeoff rolls 4 and 5 separate so that the final portion of the yarn of each filling is taken directly from the supply package. After a filling break or upon starting up of the loom, in order to insure that the length of the first weft yarn is proper, a movable guide arm 14 holds the yarn outside of the takeoff rolls 4 and 5 and the yarn is manually withdrawn from the supply package. At the end of the first stroke of the rapier the rolls 4 and 5 are separated.

  • Patent number: 4300526
    Abstract: A woodburning stove having an inner housing and an outer housing spaced therefrom providing air passages therebetween. A blower circulates air through the air passages for absorbing heat from the walls of the housing and exhausting the heated air into the room where the stove is located. A substantially horizontal plate is spaced below the top wall of the inner housing defining an afterburner space. A duct extends between the passages extending between the two housings and the afterburner space. The duct is provided with a valve so that fresh air can be controllably applied to the afterburner space for causing combustion of gasses flowing through the afterburner space. A fresh air duct extends along the side of the stove and connects with the blower for supplying fresh air from the front of the stove to the blower.

  • Patent number: 4298473
    Abstract: A filter for removing solids from a liquid of the type wherein a rotatable basket or drum has media inside straining from inside out. A power operated conveyor is mounted in the drum above the axis of rotation for receiving and positively removing solids. Thus, a liquid level is possible above the axis of rotation but below the conveyor so that a large filter area is in contact with the liquid while not interfering with the operation of the conveyor. A retractable scoop is provided for positively delivering the solids to the conveyor with an alternate sealing arrangement. A discharge ramp is carried adjacent an end of a baffle which extends above a liquid inlet upwardly toward the conveyor and is spaced from an inner wall of the drum to collect solids therebetween and accommodate the scoop for their removal. An improved means for equalizing the distribution of the liquid within the drum is also provided.
