Abstract: A latching assembly, such as for use in assembling and disassembling mating foamed insulating panels, may have housing components of inexpensive materials such as cellulosic or non-structural plastic materials. A cam shaft passes through an opening in a latch, the cam shaft mounting a cam keeper which has its peripheral surface engaged by a friction clutch (e.g. a cantilevered tongue) which supplies a radial or axial spring force from the exterior of the cam keeper to provide high level of predictable friction force. The cam shaft, and a latching pin for cooperation with hook portion of the latch, are mounted by metal or structural plastic flanges which engage the inexpensive housing components. An external clutch, such as a spring tab integral with the second metal or structural plastic flange, maintains the position of the cam shaft with respect to the flange unless the cam shaft is positively rotated.

Abstract: A metal bar is fixedly clamped by a U-bolt or similar member to the periphery of a dryer bolt head protruding outwardly of a paper machine dryer cylinder end panel. The metal bar bears one or more threaded studs which project from the face of the bar for projection through a thermal insulation end panel to fix the panel to the end face of the dryer cylinder to reduce heat loss axially of the cylinder. In one form, a sheet metal locator plate fitted between circumferentially spaced bolts bears an oblique metal bar carrying one or more studs, eliminating the need for U-bolt mounting of the metal bar to more than one bolt head.

Abstract: A paper machine dryer cylinder mounts a plurality of circumferentially spaced stud clamps which project from the inside face of the panel, each stud clamp constituting a slotted, arcuate body with a screw spanning the slot to reduce the diameter of a central opening within the body and to which a dryer bolt head is clamped to fix the panel to the end face of the dryer cylinder to reduce heat loss axially of the cylinder.

Abstract: A unitary, light weight metal I-beam frame member of generally oval plan configuration bears a first transverse spreader rod between lateral sides to support a flat swivel toe plate which extends across the top of the rod. The plate has fixed at its center a flexible strip material toe binding for partial wrapping of its opposite lateral sides about the toe of an inserted boot of the snow shoe wearer. The I-beam frame carries opposed sharp edges at its base for improved traction. Flexible sheet material pads are laced to the interior of the frame forward and aft of the binder to resist snow shoe penetration into the snow field during use. A U-shaped traction device is fixed to the bottom of the I-beam frame member, beneath the toe plate, and is notched on its lower edge to bite into the snow.
