摘要： A variable utility chain saw apparatus which includes a mounting frame, a mounting plate removably carried in the mounting frame and a portable chain saw secured to one side of the mounting plate and including a saw blade guide plate which projects through a slot in the mounting plate and supports and guides a flexible saw blade. A chain saw guard subassembly is pivotally connected to the mounting plate to protectively shield the saw blade without interfering with the sawing function of the blade. A supporting assembly adapted for securement to a cylindrical structure is detachably fastened to a support flange which is secured to, and projects from, the mounting frame. The supporting assembly can take several forms to facilitate usage of the saw apparatus for accomplishing several precision sawing functions in the field or at a workbench, all in addition to the customary manual usages of a conventional portable chain saw.

摘要： A method of sealing building openings, such as windows or the like, which comprises initially bonding a strip of ferro-magnetic or magnetic material to the structure which defines the opening in a course around the periphery of the opening. A strip of material which is magnetically attracted to the first-mentioned strip is then bonded to a closure panel in a course position to register with said first-mentioned course. Finally, the closure panel is positioned across the opening with the two strips of material superimposed, in registry and in contact to magnetically retain the closure panel in a pre-selected position in relation to the opening.The apparatus used in carrying out the invention comprises at least two elongated strips of magnetic material having a strip of bonding material on one side thereof, at least two additional strips of material magnetically attractable to the first strips, a panel and adhesive bonding the additional strips to the panel at spaced locations on the panel.

摘要： Apparatus for sawing which can be used either in portable, manually operated form, or as a stationary bench-mounted sawing device for sawing through a workpiece along predetermined angles of cut. The apparatus comprises a portable chain saw which includes a prime mover secured to one side of a flat mounting plate. A saw blade guide plate projects from the prime mover through a slot provided in the mounting plate, and in a plane substantially normal to the plane of the mounting plate. A saw blade is extended around, and guided by, the guide plate, and is protected by guard means pivotally mounted on the mounting plate. A cradle frame structure releasably receives and clamps the mounting plate in a table sawing position when the chain saw is to be so used. A cradle frame pedestal pivotally supports the cradle frame structure for pivotation about a horizontal axis. A pivotally supported turntable is positioned beneath and supports the pedestal, with the turntable and associated pedestal being pivotable about a vertical axis. A workpiece-supporting table is positioned adjacent the cradle frame structure, pedestal and turntable, and has a substantially horizontal working surface located below the guide plate of the chain saw.
