Abstract: A wrench comprising a handle carrying a flexible strap that is arranged as a loop with both of its ends anchored to the handle. A loop-adjusting slide is mounted on the handle for movement relative to the anchoring point and has the doubled ends of the strap slideably passing through it outwardly of the anchoring point so that movement of the slide adjusts the size of the loop. A ratchet is provided to hold the slide member in loop-tightening position and a spring returns it to its original position upon release of the ratchet.

Abstract: A kitchen appliance including a cap-gripper and a can-opener actuated by the same motor. The cap-gripper includes relatively movable jaws which are moved by a screw driven by the motor which is automatically stopped when the jaws come together. The can-opener is driven directly by the motor but a clutch is provided for interrupting the drive to the screw each time the can-opener is selectively actuated.

Abstract: A radiant heater in which the fuel is supplied at an inlet end of a combustion chamber, formed by an imperforate tubular shell, where combustion takes place, and the products of combustion are forced axially in one direction through the tubular shell, which is elongated to provide a substantial heat radiating wall, and out through an outlet end thereof. Surrounding the first shell, is a second tubular shell, which is concentric with the first shell to provide a second substantial heat radiating wall and an annular chamber which receives the products of combustion from the combustion chamber, directs them axially in a reverse direction, and permits them to discharge outwardly through radial outlets provided in said second radiating wall. Combustion is accomplished by a burner which is located at the inner end of the first shell to cooperate therewith and with the second shell in an effective manner to obtain maximum combustion and radiation.

Abstract: A gripper which automatically grips the screw cap on a jar or the like when it is moved thereinto in order to facilitate removal of the cap. It includes a motor-operated clamp which is automatically actuated by movement of the capped jar thereinto to grip the cap and suspend the jar so that, thereafter, both hands of the user are free to grip the jar and turn it relative to the clamped cap. After the jar is separated from the clamped cap, the motor may be actuated to release the cap from the clamp.

Abstract: A door lock which can be slipped from the inside between the edge of a door and the jamb into the latch plate carried thereby and adjusted to engage the door and prevent inward swinging. It is made as a single assembly consisting of a narrow carrier strip which has a lug on its outer end for engaging the latch-receiving opening and a carriage slidable thereon which carries a pivoted locking lever having an outer end for engaging the inner face of the door and an inner end which has a restraining portion that is biased into engagement with the adjacent face of the carrier strip and which will engage the strip more firmly when inward pressure is exerted on the door. The carriage also carries a releasing lever for engaging the locking lever to swing it in a reverse direction to release the restrainer portion from the strip and permit inward sliding movement of the carriage to disengage the outer end of the locking lever from the inner face of the door.
