Abstract:

A glass cutter having a cutting wheel rotatably mounted at one end thereof. A cutting fluid reservoir is situated within the tool housing at the end remote from the cutting wheel. The cutting wheel is mounted on a support member which is spring biased to provide a constant cutting pressure. A part of the wheel supporting member cooperates with the interior of the housing to form a valve which allows cutting fluid to flow through the wheel when the wheel is displaced against the action of the spring toward the housing during a cutting operation. A wheel cover pivotably mounted to the housing adjacent the cutting wheel has a closed position in which it protects the cutting wheel, and an open position in which the cover acts as a cutting guide.

Abstract:

A hollow wall fastener using a specially shaped or conventional toggle bolt and a toggle anchor which is pointed and which has an open groove for receiving the toggle bolt. The end of the groove has a threaded portion which cooperates with a threaded portion of an aperture opposite the groove to permit the anchor to pivot with respect to the bolt to a position where the bolt is threadably engaged and locked in the threaded portions of the anchor, forming a "T" configuration behind the surface of the hollow wall. Thereafter the bolt may be rotated, e. g. by turning a screw or fastener body, to draw the anchor tightly against the interior of the hollow wall.
