Abstract: A quick release fitting for securing seating or other equipment to a section of aircraft floor track channel comprises a lower jaw member, an upper jaw member and multiple T-shaped cam members nested between locating dowels extending from the lower surface of the lower jaw member. The locating dowels are disposed in a plurality of adjacent cutouts in the floor track channel to locate the lower jaw member, and with it the rest of the quick release fitting. As the cam members are rotated to engage the aircraft floor track channel, the camming action draws the upper and lower jaw members together to squeeze a flange attached to the piece of equipment between the beveled facing surfaces of the upper and lower jaw members. Use of multiple T-shaped cams engaging the floor track channel adjacent a plurality of adjacent cutouts allows for better distribution of load along the floor track channel and the use of beveled jaws to support the equipment allows for angular misalignment of adjacent floor track channels.

Abstract: A collapsible plunger (10) for use in a pump is disclosed having a load carrying cylinder (12) forming in inwardly facing tapered end (14), a plug (16) forming an outwardly facing taper (18) mating the inwardly facing tapered end of the cylinder, a stud bolt (20) engaging plug 16 on one end, a plunger clamp end (22) abutting the cylinder on the opposite end and a nut (24) engaging the other end of the stud bolt. The nut is free to move away from the plunger clamp end so that the stud bolt is never in compression. The tapered end of the cylinder will yield to the plug at a predetermined force. The abutment surfaces (30 and 32) of the cylinder and plunger clamp end permit some relative movement between the two.
