  • Patent number: 4174815
    Abstract: A machine and method for winding coils of wire on a slotted core of an armature core assembly. The machine has a holder for releasably supporting the armature core assembly in an upright position. Rotatable annular members located adjacent opposite sides of the core have holes for accommodating wires that are wound on the core. Chucks mounted on the annular members guide the wires moving from the annular members into two pairs of slots in the core. A motor connected to the annular members with a common drive structure rotates the annular members in opposite directions to wind two coils of wire on the core. A core indexing motor drivably connected to the holder operates to sequentially index the core during the winding operation.

  • Patent number: 4147331
    Abstract: A plaster spraying and concrete mixing machine comprised of a frame chassis, a rotatable top loading horizontally axis mounted drum type mixing tank with a center mounted rotatable mixing shaft and mixing paddles therein, and a gravity fed Moineau type progressive cavity pump mounted to the bottom of the mixing tank for pivoting therewith. A primary power source and driving mechanisms provide for turning of an air compressor, the mixing paddles, and the Moineau pump which enable the machine to mix and spray plasters and other cementitious materials. The embodiment of a selectively rotatable mixing tank provides that the machine can also mix and conveniently fully discharge batches of concrete or mortar. The pump is mounted directly to the bottom of the tank with the drive arrangement permitting the pump to pivot with the mixing tank between its mixing and dumping positions.

  • Patent number: 4145771
    Abstract: A locking device for use with a toilet provided with a seat and cover or lid assembly. The device provides the locking of the cover to the toilet bowl so as to prevent access to the interior of the bowl by small children or persons lacking knowledge of its operation or suitable dexterity. A flat locking strap of suitable length is secured at one end to the top of the toilet seat cover. The strap is provided with a tapered section near its free end which terminates in a grippable handle. A lock cylinder is attached to the toilet bowl exterior in position to receive the tapered section of the locking strap. The lock cylinder has a longitudinal slot and internal bore sized to permit only an edgewise insertion or removal of the tapered section of the locking strap. When the toilet cover is lowered and the locking strap inserted and turned flat within the lock cylinder further movement of the locking strap is prevented, thus locking the toilet seat cover closed.

  • Patent number: 4143430
    Abstract: This invention relates to water conserving devices to be used in the water closets of bathroom toilets. The devices may also find applications in other liquid containing and discharging vessels. The invention consists of a partition wall or alternatively a minitank installable in the water closet of a toilet so as to divide the water closet into two separate liquid holding compartments. A flapper valve with a magnetic closure, fitted into the partition wall or into the minitank, opens and closes a port which communicates between the compartments. The actuating means of the flapper valve is operably connected to the existing trip lever of the water closet in such a way that the valve will be actuated only after the existing discharge valve has been actuated first. This arrangement permits the user to discharge water from one or both compartments of the water closet according to his needs.
