Abstract: Nestable trays are part of a pill crushing device. The trays have cylindrical midportions, spherical end portions and a planar flange. The pill crushing device has an anvil or mortar portion to engage a bottom tray, and a hammer or pestle portion to engage a top tray. The anvil portion has a recess the perimeter of which supports the bottom tray flange. A finger gap is conveniently left in the perimeter for access to the bottom tray. The hammer portion extends between two pivotable lever arms and has sufficient tolerance to allow limited independent movement of the lever arms, which in turn allows relative movement of the trays to crush pills. The hammer can contact the top tray, and may be of cylindrical form with hemispherical ends, which can itself nest in the top tray, in another version it is slightly larger and does not nest but engages the tray near the top. In a third version the cylindrical hammer has end blocks, the cylinder registers the top tray, while the blocks engage the top tray flange.

Abstract: A goal structure for a game such as ice hockey provides a safety net which is constructed in the conventional form to provide a rigid pair of posts and cross-bar together with net supports extending rearwardly of the posts. The goal structure can be attached to the playing surface or ice by an assembly mounted wholly within the posts comprising a spring and cable, the cable passing axially of the post through an apertured guide block at the end of the post into an anchor bolt within the ice. An upper end of the spring is movable axially to apply and release the spring tension either by a transverse pin which extends into slots in the wall of the post or by an axial pin which can be held in a tensioned position by a latch. The anchor bolt in the ice allows the post to slide sideways across the ice. A plug can be placed in the ice surface when the post is removed to prevent water entering the fixture when flooding.

Abstract: A door and door jamb assembly is provided either with a kit of parts or as an assembled unit and includes a door and surrounding door jamb together with mounting brackets for the door jamb and hinges for supporting the door on the door jamb. Both the inner surface of the door jamb and the outer peripheral edge of the door are tapered so that in the closed position they are closely adjacent and parallel with a sealing strip mounted in a recess around the periphery of the door edge. The door jamb is manufactured so as to provide a rigid structure which can be mounted on the frame of the building with the brackets which allow movement between the frame and the door jamb so that the door jamb remains rigid and rectangular despite any shifting of the building. A wiping compressing action of the seal on the tapered surface of the door jamb provides a large compressing force for the seal which improves the sealing effect.
