Abstract: A portable headlamp that is particularly designed for use with bicycles integrates a number of essential features and functions desired by modern bicyclists. The headlamp has an easily removable and universally mountable fastening system that requires no tools to install. The mounting system includes a rotary joint that enables a headlamp to be pointed in any desired direction while maintaining a constant friction that can be set by the user. A focussable light beam enables the operator to vary the light distribution pattern, thereby making the headlamp suitable for use under a number of different conditions. The electrical system for the headlamp can be readily upgraded to accommodate the needs of different riding conditions, without requiring additional parts.

Abstract: A ratchet spool mechanism including a rear or bottom housing having a central column, and positioned around the central column a belleville-type spring, positioned thereover a rotary spool having affixed therebetween two lengths of twine and positioned over the top portion of the spool a rotary cap having beveled projections which cooperate with correspondingly positioned orifices in the top surface of the rotary spool whereby operation of the belleville spring, the beveled surfaces and the orifices provide for a locking mechanism and one-way rotation to tighten or draw in the twine, and upon pressing the rotary cap downward against the belleville spring, the beveled projections become disengaged from the orifices, and the spool may be rotated in either direction.

Abstract: A cam buckle for adjustably securing a strip of web-like material includes a pair of side walls having front and rear ends, a top wall extending between the side walls, a first bar extending between the side walls below the top wall and a second bar slidably mounted between the first bar and the top wall. A loop is pivotally attached to the side walls rearwardly of the second bar, and one end of the strip is secured to the loop. The buckle is pivotable relative to the loop between locked and unlocked positions. The other end of the strip is looped around the second bar when the buckle is in the unlocked position, and the end of the strip is secured to the remainder of the strip by hook and loop fasteners. The buckle may be cammed over center to the locked position to tighten the strip.

Abstract: A two part, over center buckle for belting. The buckle has a retention member on one part of the buckle which will engage a detent on the second part of the buckle when the buckle is closed. The retention member holds the buckle closed against normal vibration and jarring.

Abstract: A quick release two piece buckle of economical construction for use in situations where rapid release of a strap is required such as for example a buckle for a strap holding a scuba air tank to a back pack. The buckle has a handle member with a pair of oppositely positioned side arm portions extending therefrom. The arm portions have slots formed on the outer walls thereof, there being a detent at the entry portion of each slot. Detents are further formed on the outer walls of the arms adjacent to the bottoms of each of the slots. One end of the strap is attached to a cross arm extending between the two side arm portions. The other end of the strap is connected to an attachment member which has a pair of opposing arms. Each of the arms has an inwardly extending post member at the end thereof which is adapted to slidably fit into a respective one of the slots of the main body portion.

Abstract: A clamp band which includes a strip member having an intermediate portion formed to substantially conform to the outline of an article to be fastened and two ends projected outward from the intermediate portion and a lever member welded to the two ends of the strip member. One of the two ends of the strip member extends approximately tangentially from the intermediate portion and the other extends to make an acute angle. The lever member is welded to the outside of the end located nearer the intermediate portion of the these ends when two ends of the strip member are brought down. The lever member is formed to contact closely an outer peripheral surface of the strip member and has high hardness edge portions extending longitudinally thereof.

Abstract: In a binding device comprising a serrated strap engaged through a leader of an assembly for adjusting the binding tension, the strap can be locked by tightening within the leader with the intermediary of a wedge mounted movably in the leader itself.

Abstract: This wristlet clasp with unfolding buckle has a central portion made of two curved plates of which the relative position is adjustable and which can be secured by means of screws, the arms hingedly connected to the ends of this central portion being provided with side webs adapted to be secured by snap action to the widest element of the central portion of the clasp. The ends of the two arms to which the wristlet sections are attached and the gap possibly left between these ends in the closed clasp position are concealed by a cover plate adapted to be decorated.

Abstract: In order to permit the quick release of a motorcycle rider's helmet when a bee or wasp is trapped inside the visor, a quick release arrangement for operation with only one hand is provided. The normal strap arrangements for a helmet include a first strap extending from one side of the helmet and carrying two D-Rings secured to the end of this strap. The other strap is threaded through the two D-rings, and then back through the outer one of the two D-rings so that friction between the two portions of the second strap holds the helmet tightly in place. The present disclosure involves the addition of a release member which extends around the second strap between the point where it is threaded through the two D-rings and the point where it extends back through the outer D-ring. By pulling on this release member, the strap assembly may be released with only one hand so that the motorcycle rider can continue guiding the motorcycle with his other hand.

Abstract: A toggle clamp assembly for a flexible hose includes a flexible strap having a friction grip buckle for securing the ends of the strap into a loop around a hose and a toggle lever having one end attached to the strap and adapted to pivot from a non-tensioning position to a tensioning position for applying tension to the strap for clamping it about a flexible hose. The toggle lever includes a slot for receiving a twist fastener for fastening or holding the lever in the tensioning position.

Abstract: An adjustable emergency fan belt is provided which substitutes in an emergency as a fan belt. The emergency fan belt has a plurality of belt links that may be used in any combination with a main belt to produce a belt of various lengths. Installation of the belt around the fly wheels is relatively simple and requires no mechanical skill or tools.

Abstract: A quickly tensioned divider line for swimming pools is provided, comprising, in combination, a first divider line adapted for attachment to a first fixed location in a swimming pool; and a tensioning toggle attached to the line, and adapted for attachment to a second fixed location in a swimming pool, optionally, via a second divider line, the first and any second line thereby being located with the toggle in a divider line position in the pool; the toggle having first and second toggle arms, the first toggle arm being pivotably mounted on the second toggle arm, and movable between retracted and extended positions, in the retracted position being axially coextensive over at least a part of its length with respect to the second arm, and in the second position being axially extended over at least a part of its length with respect to the second arm; attaching means pivotably mounted on the first toggle arm, for movement therewith between its retracted and extended positions; and attaching means on the second tog
