| 20110068239 | ATTACHMENT FOR FASTENER DRIVEN BY POWDER CHARGE SETTING TOOL - A connector of frangible material for mounting on the piercing end of a nail-like fastener, connects the fastener to a bracket or clamp. The bracket has a conical frustrum-shaped aperture. The connector has a conical frustrum-shaped leading end that fits into the conical frustrum-shaped aperture in the bracket. The trailing end of the connector grips the fastener. The connector locks to the bracket by passing its trailing end through the leading opening of the conical frustrum-shaped aperture and snugging the conical frustrum leading end of the connector into the conical frustrum-shaped aperture in the bracket. | 03-24-2011 |
| 20100000173 | SUPPORT STRUCTURE FOR CAST IN PLACE CONDUIT, JUNCTION BOXES AND SIMILAR STRUCTURES - Poured concrete floors and ceilings in buildings contain electrical conduit, air conditioning conduit, plumbing and junction boxes, for example. These conduits must withstand the rigorous activity of a construction floor and the concrete poured on them during the construction phase. Rod support structures made out of steel rod stock are used to hold the conduit and junction boxes in place on a temporary plywood floor in between rebar. The support structures have feet. The poured concrete floor covers the conduit, junction boxes and support structures. The footprint of each of the support structures is designed to be as small as possible by having minimum contact with a temporary plywood floor. When the plywood floor is removed, the support structures are substantially buried in the concrete. The concrete floor is underneath the feet, providing minimum exposure of the feet to the surface of the concrete next to the plywood floor. | 01-07-2010 |
| 20090199504 | SUPPORT STRUCTURE FOR USE WITH METAL BEAMS - A support bar for spanning a pair of metal studs is attached to the studs by gripping fasteners formed at the ends of the support bar or attached to a horizontal support beam by a gripping fastener at one end. The gripping fastener is formed out of the support bar in the form of a first loop that extends from the first end of the bar and lies in a first plane, substantially perpendicular to the rod, with a second loop extending from the first loop lying in a plane substantially perpendicular to the first loop. In a second embodiment, the gripping fastener is formed out of the bar as a series of slots in the bar, perpendicular to the central axis, for a short distance along its length, at the ends. The slots are sized to fit the thickness of the metal stud. | 08-13-2009 |
| 20080302846 | EXPLOSIVE DISCHARGE ACTUATED TOOL FOR DRIVING FASTENERS - An explosive discharge actuated tool for driving fasteners has a barrel with a closed bore, an interchangeable nose piece to accommodate different length fasteners and a piston that is manually reset to firing position by a spacer-fastener being inserted into the barrel. | 12-11-2008 |
