Abstract: A level having a pair of opposed edge rails, a web connecting the edge rails together, one of edge rails having an edge rail window therein with a cavity in the web communicating with the edge window. A vial assembly is mounted at said cavity in which the vial may be viewed from the edge rail window or from the sides of the web. Web openings may also be provided in the web with vial holding assemblies mounted in each web opening.

Abstract: A vial having an outer wall which is straight and cylindrical and a curved inner cavity. The inner cavity is curved in substantially uniform arc. The apex of the curved cavity is closer to the cylindrical outer wall of the vial than the ends of the inner cavity. The inner cavity is substantially uniform in cross section throughout its length.

Abstract: A mechanism and method for accumulating sheet stacks from a continuous web having sheets printed both in side-by-side relationship and with the sheets behind each other. Slitting the continuous web lengthwise between said side-by-side sheet and cutting the web transversely between the sheets behind each other sheets to separate the printed sheets. Accumulating the printed sheets into separate stacks and stacking the separate stacks one on top of the other in offset relationship to each other and moving the offset stacks into a receptacle, such as a cassette.

Abstract: A clamp having first and second handle assemblies with each handle assembly having a jaw, a hand grip and an intermediate portion. The handle assemblies are pivotally mounted to each other at their intermediate portions for movement between an open position and a predetermined closed position. A spring is provided for biasing the hand grips and jaws to an open position. A locking mechanism is provided to lock the jaws in the predetermined closed position. The locking mechanism comprises a rack mounted on one of the hand grips and a pawl mounted on the other hand grip, each of which have teeth adapted to mesh with each other to hold the jaws in the predetermined closed position. Mechanism is also provided to release the pawl teeth from the rack teeth to permit the jaws and hand grips to move to an open position.

Abstract: A mitre box having a base and a saw holder assembly pivotally mounted for angular movement over the base. The saw holder assembly is adapted to hold a saw and is capable of being locked at a predetermined angular position over the base.

Abstract: A foldable tool having a pair of jaws pivoted to each other on a pivot pin, each jaw having a head and a shank, a spring mounted between the shanks of the jaws, a hollow handle pivotally mounted at one end to each of the shanks and foldable relative to the jaws. The hollow handle having a plurality of auxiliary tools pivotally mounted therewithin, the spring adapted to keep the jaws in a partially open position.

Abstract: An article dispensing mechanism in which a plurality of stacks are mounted on a platform. Each has a plurality of articles such as paper sheets. The platform is moved from an article feeding position to a non-feeding position. An article feeding mechanism is mounted above a stack at the article feeding position. The article feeding mechanism feeds an article from the top of a stack at said article feeding position. When a stack at the article feeding position is devoid of articles, the platform is moved from the feeding position to the non-feeding position to present another stack to the feeding position.

Abstract: A miter box having a base and opposed side walls. A one slot in each of the side walls in alignment and coextensive with each other. A channel formed in the base. A holding assembly having a guide extending into the channel and movable along the channel relative one of the side walls. A locking element to lock the holding means at a predetermined position along the channel and at a predetermined space from the side wall.

Abstract: A stack control mechanism comprising a mechanism for feeding and accumulating sheets to an accumulating area. A control mechanism for controlling the feeding of the sheets to the accumulating area which includes emitting an impulse or vibration onto that stack ad receiving vibrations or impulses which are reflected from the stack. The feeding mechanism is responsive to the controlling mechanism to adjust to rate of feeding of sheets to the accumulating area.

Abstract: A feeding mechanism comprising an accumulating area mechanism for feeding sheets into the accumulating area to form a stack, exit mechanism, mechanism for moving the stack of sheets from the accumulating area through the exit mechanism, support mechanism are provided to keep the trailing edge of a previous sheet fed in the accumulating area uplifted until the leading edge of a subsequent sheet is moved beneath a previous sheet.

Abstract: A foldable multi-tool having a pair of jaws pivotally mounted to each other with each jaw having a head and a shank. A handle is pivotally mounted at one end to each of the shanks and foldable relative to the jaws along a first pivot pin. The handle has a hollow area comprising side walls, a bottom wall and an open top. The interior of the hollow area has a space to receive the jaws when the handles are folded relative to the jaws. The hollow area has a seat on which the jaws are seated when the jaws are in their folded position. The jaws have outer surfaces and the seats have an area which is contoured in a manner similar to the contour of the outer surfaces of the jaws.
