| 20080271409 | Method of Attaching Reinforcing Bars - A method of attaching and aligning reinforcing bars includes providing a plurality of molded plastic clips having first and second parallel seats and a third transverse seat, all seats of equal size. A lower seat of a clip is pressed over a first reinforcement bar, then a second reinforcement bar is pressed into the upper seat to attach two bars of equal size in parallel. Another identical clip can be used to attach a third bar transverse to the first two bars, all the bars being of equal size. | 11-06-2008 |
| 20090301025 | Telescoping Chair For Supporting Bars - A chair for supporting bars is comprised of telescoping sections which lock in an extended position. The chair is intended for supporting the reinforcing bars utilized in reinforced concrete construction, but can also support other long bodies. The sections of the chair can be extended and locked individually, so the height of the chair is determined by which sections of the chair are extended and which sections are collapsed. Each section may have two or more different locking heights to increase the height adjustability of the chair. | 12-10-2009 |
| 20110107714 | System For Attaching Reinforcing Bars - A system of attaching and aligning both parallel and transverse bars for supporting a concrete matrix includes a plurality of substantially identical molded plastic clips for alternatively attaching and holding two parallel reinforcing bars of equal diameter or two transverse reinforcing bars of equal diameter. | 05-12-2011 |
| 20110107719 | Bar Connecting Apparatus With Clip Advance - An apparatus for connecting bars includes a clip string, a barrel having a clip receiving cavity, with a terminal clip of the clip string received in the clip receiving cavity. A drive is received in the barrel and extends proximally from the barrel. The drive includes a hammer received in the barrel. The hammer reciprocates longitudinally within the barrel for contacting and expelling the terminal clip from the barrel. A cam guide is connected to the drive. A cam plate having a cam track is pivotally connected to the barrel. The cam guide engages the cam track such that the cam plate pivots back and forth as the drive is moved distally and proximally relative to the barrel. At least one finger is connected to the cam plate such that the finger engages and advances the clip string end of the clip receiving cavity as the cam plate pivots back. | 05-12-2011 |
| 20110139644 | Clip String For A Bar Connecting Apparatus - A clip string includes a plurality of connected clips. Each clip includes a downwardly open lower seat for receiving a reinforcing bar from below, a downwardly open upper seat for receiving a reinforcing bar from below, and an upwardly open upper seat for receiving a reinforcing bar from above. The downwardly open upper seat is oriented transversely to the lower seat. The upwardly open upper seat is oriented parallel to the lower seat. At least one connection point is defined on each clip, and the plurality of clips are connected at the connection points such that all the clips are consistently oriented. | 06-16-2011 |
| 20110308192 | Rebar Clip For Joining Different Size Bars - A rebar clip is provided for joining a larger diameter rebar to a smaller diameter rebar transverse to the larger diameter rebar. In a first embodiment the clip includes diameter reducing tabs extending into upper arches of the clip for engagement with smaller diameter bars crossed on top of larger diameter bars. In a second embodiment the clip includes diameter reducing tabs extending into lower arches of the clip so that the clip may hold larger diameter bars on top of smaller diameter bars. A guide track for a clip applying gun is provided which allows for use with either version of clips and with clips of the same nominal diameter for joining equal size bars. | 12-22-2011 |
| 20120055578 | WIRE TWISTING TOOLS AND METHODS - A wire twisting tool provides a rotatable jaw housing defining an interior cavity and a housing slot shaped for receiving one or more strands of wire. One or more jaw members are disposed in the interior cavity of the jaw housing. The jaw housing is generally rotatable relative at least one jaw member. At least one jaw member advances inwardly during jaw housing rotation and is operable to engage the wire. One or more jaw members can be rotated simultaneously with the jaw housing for twisting the wire. Methods of twisting wire using a wire twisting tool are also provided. | 03-08-2012 |
