Abstract: A chop saw comprising a table, pivot member, saw assembly, upper guard, lower guard and lever utilizes the lever to maintain the position of the upper guard and lock the saw assembly in the upper rest position by engaging the lower guard with an extension of the lever. Disengagement of the lever from the lower guard, and pivoting of the saw assembly to the lower engaged position causes the lever to re-engage the lower guard to further open the lower guard and expose the blade.

Abstract: A circular saw (14) has blower attachments (10) and (12) for producing a sufficiently strong air current directly in front of the circular saw blade (18) to blow away saw dust from about the lead guide (34) that is aligned directly in front of the saw blade. The lead guide is mounted at the front edge of the foot (30). The attachment (10) is a fan mounted about the arbor of the circular saw and abuts the saw blade to also provide damping effect that reduces noise vibration. The attachment (12) has a funnel inlet section (60) mounted against the exhaust vent section (38). A self supporting flexible pipe (66) extends from the funnel inlet section and has a free standing distal end (67) that can be adjustably pointed to the lead guide (34) to allow passage of air flow from the exhaust vents to the lead guide.

Abstract: Device for cutting a pipe (1) transporting fluid in order to stop the circulation of the fluid at any point, comprising a casing (2, 3) susceptible of being sealingly mounted on the pipe (1). The casing (2, 3) contains at least one blade (8) which is driven in rotation and feed motions so as to cut off the pipe (1) by sawing it transversely. The blade (8) forms a stop surface to the circulation along the section plane of the saw blade. The device is useful in the cutting of fluid flow in pipes and particularly in the case of accidents such as fires in oil wells.

Abstract: A chop saw arrangement having an improved lower blade guard pivoting mechanism. An upper safety guard is pivotally supported to a hinging member, and a circular saw blade is rotatably supported to the upper safety guard. A collar is attached to the upper safety guard, and a swingable arm pivotally connected to a supporting arm has a cam portion engageable with the collar. Angular position of the swingable arm is defined by the abutment between the cam and the collar. The swingable arm has an end portion pivotally connected to one end of a link member whose other end is pivotally connected to a lower blade guard. The lower blade guard is pivotally supported to the upper safety guard coaxially with the circular saw blade. Angular position of the lower blade guard is defined by the pivotal movement of the swingable arm through the link member.

Abstract: A rotary grooving or grinding drum is mounted about a drive shaft. The drum has an inner core of steel, an intermediate sleeve of neoprene rubber and an outer sleeve of steel. The neoprene intermediate sleeve provides absorption of the shocks, jars and harmonic vibrations that the drum undergoes during use. The exterior surface of the outer sleeve is provided with a plurality of cutting segments disposed in a particular configuration depending on whether it is desired to groove or grind the surface of the concrete or asphalt pavement. Each cutting segment or group of segments may be separately removable mounted on the exterior surface of the outer sleeve so that worn out cutting segments can be individually replaced.

Abstract: A saw guide is provided with a mixture of air, oil and water to lubricate and cool the saw and guide. The lubricant mixture is developed by a liquids mixer constructed around an oxyacetylene cutting tip. Greatly reduced water consumption is observed resulting in a drier working environment and reducing the amount of clean-up required.

Abstract: A portable self-contained gas operated hand saw is provided having a housing with a carburetor an engine therein, a handle having a trigger coupled to the carburetor mounted at one end of the housing and a saw blade mounted at the other end of the housing. The saw blade housing has a worm gear driven rotatable shaft to which a saw blade may be keyed for rotation. The worm gear is driven by a centrifugal clutch driven by the engine. Fans are provided for rotation with the clutch and saw blade for cooling the saw in addition to the normal cooling of the engine. Anti-vibration means are provided to isolate the handle and trigger from the engine. The engine is suspended from a rubber mount allowing it to vibrate freely, thereby isolating vibration from the saw blade housing, saw plate, and handle and trigger.

Abstract: In an annular saw force-exerting mechanism (56, 57) is provided so as to act on flange-equipped support rollers (40, 41) for the saw blade (8). The support rollers have at least one flange (44) engaging a groove in the web portion of the saw blade. The force-exerting mechanism acts essentially only in the axial direction of the support rollers essentially parallel to the plane of symmetry of the saw blade towards the centre of the saw blade. Alternatively, force-exerting mechanism is provided so as to act on a drive pulley for the saw blade essentially only in a direction perpendicular to the axis of rotation of the drive pulley, parallel to the plane of symmetry of the saw blade outwards from the centre of the saw blade. In both cases the drive surfaces (22, 38) of the drive pulley and the saw blade are pressed against each other, and the inner edge of the flange on the support rollers is pressed against the inner edge of the groove in the web portion of the saw blade.
