摘要： A saw blade includes an elongate and helical or flexible blade member having an outer peripheral cutting edge for allowing the blade member to be engaged into and engaged around a work piece without being maintained perpendicular to the work pieces and for allowing the blade member to be operated by the users. The blade member may include two elongate and planar blade elements superposed with each other and each having the cutting edge formed on the outer portion and extended out of an inner portion of the other blade elements for allowing the cutting edges of the blade elements to be exposed for easily working on or cutting the work pieces.

摘要： Disclosed is a hand held, cordless electric, coping saw, which has a "U"-frame with a handle at one end of the "U". A battery and motor power the saw. The blade of the saw is endless and is round cylinder-type flexible blade trained in a generally rectangular loop about four wheels, one mounted in each corner of the "U", three of them idle wheels and one of them functioning as the drive wheel. The drive wheel is located at the handle end corner of the "U". At the other end of the "U", the frame has a "floating" corner piece housing one of the idler wheels and being spring biased away from the main part of the frame to provide saw blade tensioning.

摘要： A cast system, which includes: a padding layer configured to be disposed within a cast and support a portion of a patient's limb; a casting material which hardens around the padding layer and form an outer shell of the cast surrounding the patient's limb; and a wire saw configured to be disposed within the cast and extend along a longitudinal axis of the cast. The wire saw has a cutting surface which is at least partly enclosed by a plastic sheath. By enclosing the wire saw cutting surface in a plastic sheath, the saw does not lock up during the cutting operation, cutting is facilitated, allowing for easy and safe removal of the cast by pulling at least one end of the wire saw so as to cut through the outer shell of the cast.

摘要： A pocket safety saw that can be carried by a detention officer or psychiatric personnel without fear that it could do harm to another patient, inmate or guard is described. The pocket safety saw may be used to quickly cut down a suicidal patient or detainee from a hanging suicide attempt. An exemplary pocket saw comprises a handle, a saw portion, saw support, and safety saw element. A safety saw element is a saw element that will not cut human skin when pressed and reciprocated against the skin. The safety saw element may be used to cut fibrous material such as rope, cord, fabric and the like. A pocket safety saw may have one or more frangible features that cause the safety saw element to fracture when removed from the saw support. A frangible feature may be a removed portion of a safety saw element.

摘要： A removeable attachment for a powered tool includes a frame with a continuous loop blade positioned in a coplanar relationship with the frame along a system of blade guides so that a cutting surface of the blade faces a desired cutting area. The relative positions between the frame arms, the frame handle, and the blade provides a degree of stability and control that allows the operator to precisely and accurately control the cutting surface of the blade along curves, notches, and protrusions, including those involved in coping and sanding. In addition, this arrangement results in a compact design that positions the cutting surface in close proximity to the handle.

摘要： A motor saw for cutting wood or stone includes a continuous wire loop (18) which carries uniformly-spaced cutting elements (25) and which is tensioned over a saw guide bar (17), from a drive wheel (30) mounted in the machine housing (15) to a loop-guiding sprocket wheel (20) at the outer end of the guide bar (17), said sprocket wheel functioning as a circular saw. As the cutting elements (25) pass over the sprocket wheel (20), they drop into recesses (28) between cog-like sprockets (27) thereon. The sprockets (27) support and guide the wire loop with the cutting elements (25) hanging freely in cutting positions in the recesses (28) between the sprockets. In the case of a duplicated wire loop, a cog claim (51) on the sprockets penetrates between parts (18′, 18″) of the loop so as to prevent the freely-hanging cutting elements (25) from twisting. These cutting elements may be irregularly shaped if desired. Given an enlarged diameter, the guide sprocket wheel (20′) with the aid of the guide bar (17) attains an enhanced circular-saw effect to a depth that passes beyond the center of the guide sprocket wheel (20′).
