Abstract:
A clamping tool (10) for removing the gap between and temporarily clamping workpieces (12, 14) together for subsequent fastening and having a cable actuated toggle member (46) for engagement with one side (70) of the workpieces (12, 14) and a nut member (40) engageable with the opposite side (68) of the workpieces (12, 14).
Abstract:
A gripping jaw assembly (34) for a pull tool for setting pull type fasteners of a type which include a pin and collar and/or sleeve with the pin having a pull portion adapted to be gripped by a plurality of jaws (36) in the jaw assembly (34) with the jaws (36) having a plurality of gripping teeth (44) and with the jaws (36) being movable in separate guide tracks (31) and also supported in a manner whereby the jaws (36) and their gripping teeth (44) are maintained axially and radially in phase with each other and with the pull portion of the pin and with the jaw teeth (44) of the separate jaws (36) being maintained in phase with each other when gripping the pull portion of the pin.
Abstract:
A fastening system for securing structural members such as C-channels (10, 10a) for buildings, bridges and the like and including a fastener construction (20, 20a) for securing the structural members through spaced flanges or plates (14, 16, 14a, 16a) at locations where there is limited support between such flanges or plates (14, 16, 14a, 16a) with the fastener (20, 20a) as installed having a member (46, 46a) providing substantially direct, columnar support between the spaced flanges or plates (14, 16, 14a, 16a).
Abstract:
A tool (220) for use in installing fasteners in workpieces is disclosed. The tool includes a piston cylinder (204) and a piston (240) slidably disposed whithin the piston cylinder which defines a forward piston chamber (246) and a return piston chamber (248) within the piston cylinder. Pressurized hydraulic fluid is utilized to deploy the piston. An air return chamber is defined in part by within a handle (202) of the tool. A supply of pressurized air is connected in fluid communication with the air return chamber. A one-way valve (348) is positioned between the pressurized air and the air return chamber. The tool further includes a pintail bore which includes a passage (378) extending through the nose assembly (206), the piston, and the back cap (210). An air channel (384) connected to a supply of pressurized air is connected to the pintail bore. An air restriction mechanism blocks the flow of air out the nose of the tool and a pintail retaining device prevents detached pintails from exiting out the nose of the tool.
Abstract:
A pintail fastener installation tool includes a nose piston cylinder (12) which surrounds a nose piston (14) having bore (20) which is aligned with a jaw opening (22) of a nose assembly (30). The nose piston (14) also has a venturi bore (50) which meets the bore at an angle. When connected to pressurized air the venturi bore (50) creates a venturi effect which suctions detached pintails out of the nose assembly (30) into a container (100). The venturi bore (50) is disabled by a slide valve (56) which separates the venturi bore from the air feed. The slide valve includes a ring (58) which is positioned around the exterior of the nose piston cylinder. The slide valve (56) is slidable between a position, which allows pressurized air to flow from the air feed to the venturi bore, and a position, which prevents air flow from the air feed to the venturi bore.
