Abstract: A bowstring which is attached to a recurve or other long bow providing a section having an abrasive circular margin used to cut wood or other substance in an emergency replacing the bowstring of the bow utilized for shooting an arrow.

Abstract: A hacksaw with an improved mechanism for applying and adjusting the tension on a blade mounted to a blade mount on a front arm and a blade mount on a rocker arm. The rocker arm is pivotally coupled to a handle and is spring biased to place an initial tension on a blade held by the rocker arm and the front arm. A rotatably mounted lever is positioned on the handle for vertically displacing a nut captured in the rocker arm to pivot the rocker arm and adjust the tension on the rocker arm-held blade. An elongate top frame bar of the hacksaw defines a hollow I-beam cross-section accessible from the face of the front handle and is capable of storing saw blades. A bale screw is positioned in the front member for securing the blades in a position extending past the front handle.

Abstract: A portioning device is provided for use in cutting or leveling a food product. The portioning device comprises a handle section that is configured to be manipulated by a user, a leg section and a blade. The handle section includes an arm configured to receive a leg, a sleeve configured to slide over a portion of the arm, and an arm connector pivotally coupled to the arm. The leg section is configured to support the portioning device on a surface. The leg section includes a blade holder configured to hold an end of a blade portion, and a leg lock configured to adjustably lock the leg in a position. The blade is configured to cut an object.

Abstract: A foldable bow saw movable between a functional saw condition and a folded packable condition includes a handle arm, a top bar, a short arm, a saw blade, and a lever arm, all pivotally connected one to the other with an end of the handle arm and an end of the lever arm forming free, unconnected ends of the assembly. The free end of the handle arm includes a connecting fulcrum surface adapted to removably mate with a fulcrum surface receiver in the lever arm. Rotation of the lever arm in a locking direction about the fulcrum surface moves the pivotal connection of the lever arm to the saw blade to a tensioned functional saw condition. Rotation of the lever arm in an unlocking direction allows the fulcrum surface to be removed from the fulcrum surface receiver and the assembly to be folded to the packable condition.

Abstract: A tool machine includes an output spindle that moves back and forth and includes a drive motor. The spindle and the motor are coupled to each other via a transmission system. A longitudinal face of the output spindle and a longitudinal face of the drive motor run adjacent to each other such that the drive motor lies next to the output spindle. A very compact configuration is thereby produced.

Abstract: A blade replaceable hacksaw includes a spine with a handle connected thereto. A tension adjustor and a first blade securing portion are connected to the first and second ends of the spine. A positioning block is pivotably connected to the second end of the spine and a second blade securing portion is formed to the positioning block. A protrusion extends from the first end of the positioning block. A stop is connected to the second end of the spine and has an inclined face and a top face. When the positioning block is pivoted upward and supported on the inclined face, a first blade is connected between the first blade securing portion and the tension adjustor. When the positioning block is pivoted downward and the protrusion contacts the stop face of the stop, a second blade is connected between the second blade securing portion and the tension adjustor.

Abstract: A saw bow for a handsaw includes a saw bow body, a movable member movably mounted in a bottom of a handle of the saw bow body and movable relative to the handle along a longitudinal direction of the saw bow body, a bottom cover having a first pivotal portion pivotally connected with the handle of the saw bow body and a second pivotal portion, and a length-adjustable member having two ends respectively pivotally connected with a pivotal end of the movable member and the second pivotal portion of the bottom cover. As a result, the saw bow of the present invention can provide a congruous appearance and occupy less storage space.

Abstract: A bow saw provided with a handle on the rear end of its bow-shaped frame can be coupled to a rod (32), for instance a telescopic rod, by a rod-attachment coupling. For this purpose, the rear section of the bow-shaped frame (10) has a detent element (34) which is welded on it which is surrounded by the handle shell (30) of the handle and a device insertion pin (36) which is swingably fastened on the frame (10) by fork arms (38) in the region of the detent element (34). This device insertion pin (36) can be form-locked to the detent element (34) in the outward-swung position of the handle so that the device insertion pin (36) protrudes towards the rear and a rod (32) provided with a corresponding insertion hole and a coupling can be pushed onto it. The movement of the device insertion pin (36) into the coupling position is effected by entrainment upon the swinging of the handle shell (30).

Abstract: A saw is described as having an adjustable handle wherein the angle of the handle in relation to the longitudinal axis of the saw blade and blade holder is rotatably adjustable.

Abstract: A saw includes a handle having a channel formed in the upper portion for slidably receiving a beam. An arm is secured to one end of the beam. Two rotary members are pivotally secured to the handle and the arm for supporting a saw blade. A knob is slidably engaged in the handle and has a key for engaging with one of the rotary member and for securing the rotary member to the handle. The arm includes a stop for engaging with and for positioning the other rotary member to the arm. The beam and the arm are moved away from the handle for stretching and for securing the saw blade in place.

Abstract: The invention is to the combination of an attachment device and the combination of the attachment device with a saw blade for use with a standard hack saw frame. The attachment device has an arm that is inserted into one end of the hack saw frame where the blade is attached. A saw blade having at least one hole in a first end and a plurality of holes spaced apart in a second end is mounted between the attachment device and the hack saw frame, with one end of the saw blade extending beyond the hack saw frame such that the end of the saw blade extending beyond the hack saw frame can be used to saw in restricted or limited access areas.

Abstract: A hacksaw has an adjustable frame with an elongated rear frame member having an inverted U-shaped cross section and providing a downwardly opening channel. The rear frame rearward end portion is secured in the upper portion of the hand grip and its side walls adjacent the forward end have lower portions which extend inwardly and incline upwardly towards the forward end to provide an upwardly inclined ramp. This ramp substantially closes the channel and terminates in a lip at the forward end of the frame member, and the top wall and side walls adjacent thereto are relieved above the ramp. A front frame member of bar-like configuration having a bridge portion seated in the channel of the rear frame section, and a depending leg portion at its forward end which has a blade mounting element adjacent its lower end. The bridge portion has spaced recesses in its bottom edge in which the lip of the ramp is seated.

Abstract: A hacksaw frame having a blade holder having opposed blade clamping surfaces and means for locking the surfaces in clamping relationship loosely mounted on the frame for holding a hacksaw blade, and tensioning means on the frame for holding a blade under tension.

Abstract: A band-type abrasive strip and hand tool holder which utilizes the resilience of the holder to enable the band to be applied to the holder or removed and also the same resilience to maintain tension on the band. Modified holders allow difference size bands and a longitudinally split band allows transverse deformation to reach crevices and contours on a workpiece.
