Abstract: A strap-tensioning apparatus includes a base including two walls each formed with a first arched edge and a second arched edge, a short strap connected to the base, a spring-loaded reel supported on the base, a long strap wound on the reel, a spring-loaded detent movably supported on the walls for engagement with the reel, a handle supported on the base, and a spring-loaded detent/suppressor is movably supported on the handle for engagement with the reel. The detent/suppressor suppresses the reel when it is retained in position on the first arched edges of the walls but allows the reel to spin when it is moved on the first arched edges of the walls in a direction.

Abstract: A clutchable pry bar includes a bar member with a fitting connector; a rack member fitted with the fitting connector of the bar member, including two slots adjacent to a closed end of the rack member, and including two through holes proximate to an opened end of the rack member; a ratchet shaft inserted to the through hole of the rack member, and including a first end portion disposed on one end thereof; at least one ratchet member fitted to the ratchet shaft, a plate member movably fixed to the slots of the rack member, a returning spring between pegs of the plate member and a central extension of the bar member; a stem member to be retained with the ratchet shaft after the stem member is inserted to a radial bore of the ratchet shaft.

Abstract: A tool for creating tension of a chain on a cycle according to one embodiment comprises a wheel engaging portion; a frame engaging portion positioned opposite the wheel engaging portion; and at least one handle operatively coupled to the wheel engaging portion and the frame engaging portion such that application of force on the at least one handle is operative to bias the wheel engaging portion and frame engaging portion away from each other.

Abstract: The tensioning device for belts and the like comprises a supporting base (2), a winding reel (6) which can rotate relative to the base (2) about a respective axis of rotation (A1), a ring gear (13) which rotates integrally with the reel (6), an operating lever (14) for rotating the reel (6) in a first predetermined direction of rotation (S1) for winding the belt, a ratche mechanism (39), operating on the ring gear (13) and designed to prevent the reel (6) from rotating in a second direction of rotation (S2) opposite to the first predetermined direction (S1), the ratchet mechanism (39) comprising respective release means for allowing belt unwinding by reel (6) rotation in the second direction of rotation (S2). Further, the ratchet mechanism (39) comprises a first tooth (19) for engagement with the ring gear (13), the first tooth being designed to oscillate about two respective axis of oscillation (O1, O2).

Abstract: A rope/wire pulling device designed to provide maximum pulling pressure by the use of two handles and a non-slip ratcheting clutch which grasps the rope or wire tighter as additional pulling pressure is applied.

Abstract: A winch for controlling the tautness of a length of wire includes a generally U-shaped frame and a spindle rotatably mounted on the frame, the spindle serving as a spool on which the length of wire can be wound. The winch additionally includes a ratchet rotatably mounted on the frame in co-axial alignment with the spindle, the ratchet being fixedly connected to one end of the spindle using the combination of a threaded bolt and a washer. Furthermore, the winch includes a pawl pivotally mounted on the frame, the pawl capable of being pivoted between a first position in which the pawl sequentially engages outwardly extending teeth in the ratchet so as to limit rotation of the ratchet in only one direction and a second position in which the pawl disengages from the ratchet to allow for rotation of the ratchet in either of two opposing directions.

Abstract: A strap fastener includes a base, a shaft mounted on the base, a reel rotationally mounted on the shaft, two ratchet wheels formed on the reel, a torque spring arranged between the reel and the shaft, a lever pivotally mounted on the base, a first detent movably mounted on the lever for engagement with the ratchet wheels, a second detent movably mounted on the base for engagement with the ratchet wheels, a wedge formed on the second spring-biased detent, a handle including a first end in which a hole is defined, a second end secured to the lever and a control element extending through the handle and the lever and including a first end exposed through the hole defined in the first end of the handle and a second end in engagement with the wedge. The first end of the control element can be pressed so as to move the second end of the control element from a position for engaging the second detent with the ratchet wheels to a second position for disengaging the second detent from the ratchet wheels.

Abstract: A wire clamp device affixed to an outer end of a bar in a wire tightener of the type having a stationary wire holding clamp at an opposite end of the bar. A carrier is mounted on the bar and is also provided with a wire holding clamp. The bar is provided with a jack rack and the carrier has a jack mechanism for forcibly driving the carrier toward the first wire holding clamp so as to pull end portions of two strands of wire held by the two wire holding clamps toward each other. The wire clamp device which also has a wire holding clamp is positioned to hold the strand held by the wire holding clamp of the carrier after it has been drawn towards the first wire holding clamp so that the wire holding clamp on the carrier may be released to allow the carrier to be reset to a position near the wire clamp device, after which the wire holding clamp on the carrier is again activated to grasp again the tightened strand which it had previously held.

Abstract: A retractable tie-down assembly includes a frame, a spool rotatably mounted to the frame, a strap wrapable on the spool, and a locking device. A holder bracket is pivotally connected to an axle of the spool. A catch member is mounted in the holder bracket. A spring includes a first end attached to the holder bracket and a second end attached to an end of the catch member to thereby bias the catch member to a position disengaged from the ratchet wheel. When the locking device is in a position engaged with a ratchet wheel on the spool and thus locks the spool against rotation in a pay out direction, and when the holder bracket is manually pivoted in a direction away from the locking device, the catch member is moved to engage with and thus exerts a force to the ratchet wheel such that the spool rotates in a retracting direction. Fine tightness adjustment of the strap is achieved by simple repeated reciprocating pivotal movements of the holder bracket.

Abstract: A device for positioning cargo includes a rack slidably engaged in a tube and outstretched from the tube so as to force against the cargo in order to position the cargo within a container, a base is secured to the tube, a ratchet gear is rotatably supported in the base and engaged with the rack, a handle is pivotally coupled to the base and has a catch engaged with the ratchet gear, the rack can be easily and quickly outstretched from the tube when the handle is rotated in a reciprocating action.

Abstract: A device for quickly releasing tension in a load securement element such as high tension banding used to secure loads to railroad flat cars. The device includes a tubular housing within which a slide member is movable between set and released positions. Attachment devices for connection to the band or element and to a support are carried by the housing and slide member and are separated when the slide member moves from the set to the released position. A lock pin carried in the slide member engages the hosuing for locking the slide member in the set position, and also for guiding the movement of the slide member in the housing. A release element on the housing is readily movable in the transverse direction, as by striking with a hammer, to release the lock pin and permit the slide member to move from the set position. A bright colored surface on the slide member visible through a window in the housing indicates the position of the slide member.

Abstract: The present invention is concerned with a device for tensioning a chain. The chain tensioner in accordance with the present invention was developed in particular for securing deck cargo on ships and for binding timber bundles. As regards its technology, it is simplified as extensively as possible in order to reach reliability of operation in all possible circumstances. Owing to the simplicity of the construction, almost all maintenance becomes unnecessary and a reliability of operation is reached that meets the requirements imposed by the recommendations of the IMCO (Intergov. Maritime Consultative Organization).
