Abstract
A tool for securing items together closes C-rings to create hog rings. A drive mechanism allows the tool be used continuously for a greater length of time than heretofore possible without inserting a new string of C-rings. The drive mechanism utilizes one-way clutch bearings to provide a ratchet-like mechanism. Each time a trigger on the tool is pulled, a C-ring is closed and another C-ring is advanced to a position in which it may be closed by the same jaws. A pneumatic system moves a piston inside a cylinder to move the C-rings along a magazine towards the jaws.
Claims20
A clamping tool for closing C-rings to create hog rings, the tool comprising:
- a body comprising a handle and a pneumatic cylinder;
- a piston movable inside the cylinder, the piston being attached to a piston rod extending from the piston towards a front end of the tool;
- a movable trigger for activating the piston inside the pneumatic cylinder;
- a pair of side plates secured to the body, the piston rod being movable between the side plates;
- a pusher attached to the piston rod for engaging and moving a clamp, the clamp being fixedly secured to a shaft, said shaft being secured in position by a mounting bracket secured to one of the side plates;
- two movable jaws pivotally mounted to the side plates;
- at least one feed roller and at least one one-way clutch bearing, the shaft extending through each of the feed rollers and each of the one-way clutch bearings;
- a spring biasing the clamp rearwardly towards the body of the device;
- a magazine attached to one of the mounting plates, the magazine being adapted to receive a plurality of C-rings;
- wherein upon the trigger being pulled, the pusher moves rearwardly with the piston rod, the spring contacting the clamp and moving the clamp, shaft, one-way bearings and feed rollers in a counter-clockwise direction, when viewed from the top of the tool, the feed rollers contacting the C-rings to advance the C-rings one at a time into a clamping position from the magazine and upon release of the trigger, the pusher contacts the clamp and rotates the clamp in a clockwise direction, when viewed from the top of the tool, to load the spring for the next pull of the trigger.

A clamping tool for closing C-rings to create hog rings, the tool comprising:
- a body comprising a handle and a pneumatic cylinder;
- a piston movable inside the cylinder;
- a piston rod attached to the piston at one end and attached to a feeder blade at the other end;
- a pair of side plates secured to the body, the piston rod being movable between the side plates;
- upper and lower jaws used to close a C-ring, said upper and lower jaws being pivotally secured to the side plates and located between the side plates;
- a magazine attached to one of the mounting plates, the magazine being adapted to receive a plurality of C-rings;
- a mounting bracket secured to one of the side plates for rotatably retaining a shaft;
- a pusher attached to the piston rod for engaging and moving a clamp, the clamp being fixedly secured to a shaft;
- feed rollers and one-way clutch bearings, the shaft extending through the feed rollers and the one-way clutch bearings;
- a spring biasing the clamp rearwardly towards the body of the device;
- wherein upon the trigger being pulled, the pusher moves rearwardly with the piston rod away from the clamp, the loaded spring contacting the clamp and moving the clamp, shaft, bearings and feed rollers in a counter-clockwise direction, when viewed from the top of the tool, the feed rollers contacting the C-rings to advance the C-rings one at a time from the magazine into a clamping position between the jaws of the tool and upon release of the trigger, the piston and piston rod with attached pusher move forwardly, the pusher contacting the clamp and pivoting the clamp and shaft in a clockwise direction, when viewed from the top of the tool without rotating the feed rollers or the C-rings.

- a pusher attached to the piston rod for engaging and moving a clamp, the clamp being fixedly secured to a shaft;
- at least one feed roller and at least one one-way clutch bearing, the shaft extending through each of the feed rollers and each of the one-way clutch bearings;
- a biaser biasing the clamp rearwardly towards the body of the device;
- a trigger oriented such that upon the trigger being pulled, the pusher moves rearwardly with the piston rod out of contact with the clamp, such that the biaser moves the shaft and clamp in a counter-clockwise direction, when viewed from the top of the tool, along with rotating the feed rollers in the same direction, the feed rollers contacting the C-rings on the magazine to advance the C-rings one at a time into a clamping position and upon release of the trigger, the pusher moves forwardly into contact with the clamp, rotating the clamp and shaft in a clockwise direction, when viewed from the top of the tool, without rotating the bearings or feed rollers.
