A clamp, for example of the conventional "clothes peg" type, is provided with a wedging device 9 which may be selectively locatable between the rear ends of the two clamping members 2 so as to urge the rear ends apart, and thereby by virtue of the pivotal connection 4 between the clamping members 2 to urge the clamping jaws 3 together. In this way the wedging device 9 acts to increase the strength of the clamp in order to reduce the possibility of the items held between the jaws of the clamp fro...

A double-ended clip such as clothes pins, paper clips and the like including two elongated arms between which a floating elastically resilient fulcrum rides in a direction longitudinally of the arms. As the pin is manipulated the fulcrum snaps away from the closing end of the pin and in so doing snaps together the tips of the arms at this end.

A pivoted window frame is disclosed having an outer fixed frame and an inner pivotable frame together with a pivotable channel guide for a blind. An actuating mechanism on the movable frame can act to lock the movable frame in a closed position in the outer frame together with the channel guide or to release the movable frame for movement with or without the channel guide. The drive mechanism also actuates means for determining any one a plurality of pivoted positions of the movable frame and a ...

A vertical pivotable gate has a base with a part-circular anchoring plate and a gate member movable into raised and lowered positions, the gate member having cross-members above and below the anchoring plate and all three being apertured to receive a longitudinally slidable latch bolt serving to hold the gate member in the raised position. Upper and lower preferably resilient end stops may be secured on the anchoring plate to be abutted by a cross-member. For further support of the latch bolt, i...

A router and other cutting tools with a fixed center such as drills, shapers, milling machines, etc., used for cutting wood, metal or other materials, is provided with a fence mechanism for either a table or the base of a portable tool, for rapid and easy settings of the fence with respect to the center of the cutting tool. This is accomplished by a pivot mounting of the fence on a table or on a portable tool base, with respect to a block pivoted to the table or tool base, wherein the center of ...

A fume hood is pivotally mounted on a vertically extending axle fixed to a chemical tank and extending through a sleeve in the hood allowing the fume hood, with a flexible coupling to an exhaust blower, to pivot from a use position adjacent the tank to a position pivoted away from the tank to allow an operator to gain access to the tank. In one embodiment, the hood includes a support leg for supporting the end of the hood remote from the pivot connection to the tank.

A cabinet includes a frame extending vertically upwardly from a base. Wheels are mounted to the base for moving the cabinet over a floor. And, an elongate footrest is pivotally mounted to the base at the front of the cabinet for providing posture relief for the user.

A document feeder employs a lifting lever to lift stacked documents away from a feed roller each time a document is being fed away from the stack. In this way the separation of documents is enhanced, providing a mechanism that more readily accommodates documents of varying shapes, thicknesses, and materials. The feeder uses a motor linked by one-way clutches to feed mechanisms for documents and for labels, stacked separately. The motor is driven in one direction to feed documents and in the othe...

A nursery gate is provided with a pivoted latch. When the gate is swung to a closed position where it is co-planar with the keeper and hinge axis, the latch draw engages the keeper. At that time, a detent provided by the nose and the recess engages due to a spring movement of one of the part in the direction of the hinge axis. The gate is released for opening by a movement in the opposite direction against the spring so as to separate the nose and recess and allow the latch to pivot.

An electric jack for the connection of a module plug for signal transmission, including a base, and a cover pivoted to the base, wherein the base has two parallel side walls, a raised block on the middle, two longitudinal grooves at two opposite sides of the raised block, two pivot pins at two opposite sides of the raised block, two tongues respectively raised from the side walls, a plurality of metal terminals mounted in respective insertion slots in the raised block, a stop block for supportin...
