Abstract: A springless, double ended elastic fabric tensioner including at least two gripping members, each having a first jaw and a second jaw biased together at a first pivot point and a second pivot point wherein the first and second pivot points are set apart from each other. A compression activation site is positioned in between the first and second pivot points for activating the first and second jaws from a closed position to an open position. The fabric tensioner further includes a tensioning elastomeric member having a first end and second end and providing sufficient tension between the gripping members whereby each gripping member removably engages either the first or second ends of the elastomeric member.

Abstract: A utility knife with a rotary blade magazine also has a safety catch carried by the blade transport mechanism. The safety catch has a manually engageable actuator moveable relative to the transport mechanism between operative and non-operative positions to prevent or permit respectively sliding movement of the transport mechanism in the housing. The knife further has an end cap removably and rotatably secured in the housing, and a rotatable and removable ratchet member adjacent a rear end of the magazine, the ratchet member being connected to the magazine whereby rotation of the ratchet member effects rotation of the magazine and having ratchet teeth engageable with ratchet recesses in the housing to enable the ratchet member to be clicked from one position to another. The end cap is connected to the ratchet member whereby rotation of the cap causes rotation of the ratchet member and subsequent rotation of the magazine.

Abstract: A utility knife has a blade magazine removably mounted in a manually holdable housing and rotatable about an axis parallel to a longitudinal axis of the housing. The blade magazine has a series of radially and longitudinally extending circumferentially spaced blade-receiving slots for separately receiving thin blades having a cutting edge at at least one end thereof, each slot having an open front end to enable a blade therein to be removed from the magazine by forward movement through the front end of the slot. The housing also carries a slidable transport mechanism having a manually engageable actuator projecting from the housing and slidable in a longitudinal direction between front and rear positions, the transport mechanism also having a blade-engaging arm within the housing.

Abstract: A cutting blade and a cutting blade holder are described which, when used together provide exceptional stability to the cutting blade. The cutting blade/blade holder assembly is particularly adapted for use in combination with a carpet cutting device for cutting matched seams in wall-to-wall carpet laying installations.

Abstract: A device for cutting overlapped carpet sections so as to produce matched seams is disclosed. The device comprises a generally planar base plate having an upper and a lower surface. Two generally planar side plates are provided on the base plate adjacent the respective opposed side edges of the base plate so as to protrude downwardly below the lower surface. A handle having a longitudinal axis is affixed to the upper surface of the base plate between the two side plates with the longitudinal axis in angled relation to the upper surface and in generally parallel relation to the side plates. A cutting blade is rigidly and adjustably affixed to the device between the side plates with its cutting edge in generally parallel relation to the longitudinal axis, the cutting blade protruding sufficiently below the lower surface so as to be positionable in operative cutting relation to the overlapped carpet sections.
