ROOF CUTTER
20200325687 · 2020-10-15 ·

A roof cutter and a method of cutting a roof is provided. The roof cutter includes a base that is movable between a retracted configuration and a cutting configuration. In the retracted configuration, the blade is displaced from the roof. In the cutting configuration, the blade is positioned so as to facilitate cutting of the roof. The roof cutter includes a stop assembly and an engagement member that is configured to engage with the stop assembly when the base is in the cutting configuration, thereby establishing a maximum cutting depth. A dampening mechanism softens impacts associated with the blade moving to the cutting depth and absorbs vibrations associated with cutting the roof at the cutting depth. An adjustment assembly is configured to selectively adjust the cutting depth and/or to selectively restrain the base in the retracted configuration, thereby preventing the blade from cutting the roof.

CUTTING DEVICE

A cutting device configured to cut a workpiece includes a base and a cover plate. The cover plate includes a base plate, a pressing member, and an elastic member. A surface of the base plate facing the base defines a receiving groove configured to receive the pressing member. The pressing member defines a number of first cutter slots to allow cutters to pass through to cut the workpiece located between the base and the cover plate. The elastic member includes a connecting portion and an elastic portion. The connecting portion is fixedly coupled to the pressing member and partially extends beyond an edge of the pressing portion. One end of the elastic portion abuts against the base plate, and a second end of the elastic portion is coupled to the connecting portion.

CONDUIT CUTTING ASSEMBLY
20200198166 · 2020-06-25 ·

A conduit cutting assembly is comprised of a conduit cutting surface, a drive shaft, a top shield and a bottom guide. The conduit cutting assembly is inserted into a rotary device which provides a torque to rotate the conduit cutting assembly. The shield glides along the top surface of the conduit preventing deeper penetration of the cutting surface and deflecting dust as conduit is cut. The guide is positioned on the internal side of the conduit and prevents the cutting surface from contacting encased wiring. The distance between the bottom surface of the shield and the top surface of the guide is closely aligned to the conduit wall thickness. Conduit cutting assemblies can be customized for conduit material and conduit wall thickness. The conduit cutting assembly safely cuts through conduit without damaging encased wiring, limits incidental contact with the cutting surface, and limits contact with dust generated through the cutting procedure.

Facer for end fusion of polyolefin pipes

A facer facing the ends of polyolefin pipes for butt fusion is modular in the sense that it employs three types of modules, a drive unit, two blade holders and a motor assembly, that are separable from one another and each independently light enough to be hand-lifted along walls and up to ceilings. The drive unit module is adjustable to accommodate different guide rail spacings. The blade holder modules are interchangeable to accommodate different diameters of pipe. The motor assembly module has multispeed capability to accommodate the total area of material to be faced. Each module can be exchanged or modified without use of tools to change the geometry of the assembled facer to accommodate different fusion machines and/or diameters of pipe within working spaces dictated by the diameter of the pipe and not by a fixed geometry of a facer.
