Abstract: This invention relates broadly to an apparatus for shortening wires, cables and the like without requiring the disconnection of such wires and cutting off the ends thereof to achieve the shortening. The apparatus consists generally of a sheet metal or the like shortening device which has a degree of flexibility therein by means of which the shortening function is accomplished. The wire or the like to be shortened is affixed to lugs or the like which are struck from the edge of one portion of the device and from this portion extends a tail which is bent towards the aforesaid portion and the wire is affixed to the bend which is made in this tail portion. The amount of shortening of the wire is determined by the place where the tail is bent.

Abstract: A fastening mechanism for a safety belt comprising a locking tongue attached to one end of a safety belt and a locking case attached to the other end of the safety belt. The case pivotably supports a locking flap which selectively engages the locking tongue to lock the same in the case or to release the locking tongue. A spring acts on the locking flap to urge the same to a locking position in which the locking tongue is engaged by the locking flap. An expeller is mounted in the case for displacement to expel the tongue from the case when the tongue has been released from the locking flap. A push button including an integral cam has a cam surface on which the locking flap is engaged under the action of the spring and displacement of the push botton displaces the cam and moves the locking flap to a release position with respect to the tongue.

Abstract: A fuel burning stove for holding and burning fuel to heat the surrounding atmosphere in a room where the stove is employed. The stove includes a fire box which supports the fuel and where the combustion is sustained. An air inlet is provided to the fire box allowing the inflow of air for combustion with the fuel. The air is preheated upon entry into the fire box for mixture with volatiles formed by the burning fuel directed toward the entering air by a baffle means to effect a secondary combustion. In addition, a movable damper cooperates with the baffle to direct volatiles toward the incoming heated air when the damper is in the closed position and to provide a more direct path to the chimney when in the open position.

Abstract: A one piece cable tie for positioning first and second wires relative to one another comprising spacer means for spacing the first wire a predetermined distance from the second wire, retaining means for releasably retaining the first wire, securing means for securely holding the first and second wires against relative movement and spaced the predetermined distance, and abutment means for tightening the hold of the cable tie about the wires.

Abstract: A buckling assembly for a safety harness has two parts which can be connected and disconnected from one another. One of the parts has a member which must be actuated to allow connection and disconnection, and once the assembly is connected and closed, actuation of this member is prevented. Additionally, the two parts can only be separated in one relative orientation which will not be reached while the harness is being worn.

Abstract: A fixture for a string, a band or the like, comprising at least two spaced vertical fixing portions and a horizontal connecting portion extending between the vertical fixing portions. The material, such as a string or a band, is helically wound or coiled round the horizontal connecting portion.

Abstract: This invention relates to a clamping mechanism which is effective to produce a high compressive force on the gathered open end of a thermoplastic bag containing an appropriate product, such as food items for freezing, characterized by the fact that a high compressive force is supplied to at least two spaced portions of the gathered bag end material to effect the sealing of the bag material through cold flow of the material and without the application of any external heat.

Abstract: Apparatus for fastening spaced ends of a necklace and the like or for locking a safety pin of a badge, brooch, or the like, the invention comprises a rotatable locking member having spaced opposing bayonet slots formed in arcuate wall portions of the locking member. The wall portions are discontinuous about diametrically aligned portions of the periphery of the locking member to define aligned openings which receive a portion of a safety pin or spring thereinto, the locking member being rotatable to engage said portion of the safety pin or spring within the bayonet slot, thereby to releasably lock the pin or spring therewithin.

Abstract: A one-piece elastic fastener includes a pair of spaced elastic, generally dish-shaped head members adapted to fit on opposite sides of pieces of material to be joined. The head members each have a rim and are disposed concavely inwardly with their rims facing each other. An elastic shank member joins the head members and is adapted to pass through an opening in the pieces of material. In one embodiment an elongated loop member is centrally attached to one of the head members and is adapted to pull it through an opening in the pieces of material to be joined. In another embodiment a boss is positioned on one of the head members and a hook is used to pull it through the opening.

Abstract: A ring clamp has a pair of flexible sheet-metal strips formed into a ring with one end of each strip juxtaposed with the one end of the other strip, and the other end of each strip lying intermediate the ends of the other strips. The buckles are each formed of a pair of sheet-metal parts one of which has ends bent over and formed with channels into which fit similar channels of another latch part whose ends are in turn bent over the first part for locking-together of the entire buckle into a rigid unit without the use of welding or rivets. Furthermore each buckle has inwardly directed teeth that can bite into the object being clamped. When the ends of the clamp are drawn together to tighten it around an object the two buckles are tightly pressed against the object and prevent sliding of the two strips relative to each other.
