A combustion-powered fastener-driving tool that include a chamber member retainer assembly configured to enable the controller of the tool to prevent the chamber member of the tool from moving to an open unsealed position and to ensure the tool's combustion chamber remains sealed until the piston fully returns to its pre-firing position.

Various embodiments of the present disclosure provide a curtain wall panel bracket leveling system that facilitates leveling a panel bracket mounted to a fixture (such as an embedment or an anchor array) cast in a concrete slab.

Curtain wall panel bracket leveling system

Various embodiments of the present disclosure provide a curtain wall panel installation system. The curtain wall panel installation system of the present disclosure includes a plurality of rails each forming an elongated panel bracket spanning an entire edge or substantially the entire edge of a concrete floor slab of a given floor of a building. Each elongated panel bracket is mountable to anchors (such as embedments) cast in the concrete floor slab of a given floor of the building at discrete positions along the concrete floor. The elongated panel brackets enable the curtain wall panels to be laterally transported along the building fa&#xe7;ade to their respective installation positions, which enables workers to use a centralized crane location to hoist the curtain wall panels in preparation for installation.

Various embodiments of the present disclosure provide an embedment attachment system configured to attach to a concrete form such that an embedment of the embedment attachment system has a desired edge spacing from the concrete form. Use of the embedment attachment system of the present disclosure enables precise embedment positioning with respect to the concrete form.

Embedment attachment system

A fastener driving tool includes a power source including a cylinder, a piston with a driver blade reciprocating in the cylinder, a tool nose associated with the power source for receiving the driver blade for driving fasteners fed into the nose, and a magazine housing a supply of the fasteners. A magazine feeder mechanism is associated with the magazine for sequentially feeding fasteners into the nose, and the feeder mechanism includes a reciprocating feed piston. A conduit is connected between a port in the cylinder and the feed mechanism for diverting combusted gas for activating the feed piston. The port is disposed in the cylinder a specified distance below a piston prefiring position, the distance being reflective of a delay of activating the feed piston until the drive piston finishes a driving stroke and begins a return to the prefiring position.

A combustion nailer includes a tool housing, and a combustion engine substantially located within the housing and including a valve sleeve reciprocating relative to a cylinder head for cyclically opening and closing a combustion chamber. A control system is associated with the housing and is connected to the combustion engine for providing for a designated open time for the combustion chamber after a combustion event and before a subsequent combustion can occur.

A fastener driving tool includes a power source including a cylinder, a piston with a driver blade reciprocating in the cylinder, a tool nose associated with the power source for receiving the driver blade for driving fasteners fed into the nose, and a magazine housing a supply of the fasteners. A magazine feeder mechanism is associated with the magazine for sequentially feeding fasteners into the nose, and the feeder mechanism includes a reciprocating feed piston. A conduit is connected between a port in the cylinder and the feed mechanism for diverting combusted gas for activating the feed piston. The port is disposed in the cylinder a specified distance below a piston prefiring position, and the distance is reflective of a delay of feeding the gas to the feed piston at least until engagement between an end of the driver blade and a head of a fastener in the tool nose.

A fastener driving tool including a power source having a reciprocating driver blade, a tool nose associated with the power source for receiving the driver blade for driving fasteners fed into the nose, a magazine constructed and arranged to house a supply of the fasteners and a magazine feeder mechanism associated with the magazine for sequentially feeding fasteners into the nose. The feeder mechanism operates between a retracted position and an advanced position. An electromechanical retention device is operationally associated with the feeder mechanism and is configured for retaining the feeder mechanism in the retracted position until the driver blade is positioned to allow fastener advancement into the nose.

A combustion-powered fastener-driving tool includes a combustion-powered power source including a cylinder head and a combustion chamber defined by the cylinder head, a valve sleeve and an upper surface of a reciprocating piston, the valve sleeve reciprocable relative to the cylinder head between a rest position and a pre-firing position. The valve sleeve has a range of positions between a first sealing position in which the combustion chamber is closed, and said pre-firing position in which the valve sleeve is prevented from further movement. A lockout device is associated with the power source and has an actuated position configured for preventing the reciprocation of the valve sleeve beyond the first sealed position to open the combustion chamber, but permitting movement of the valve sleeve from the first sealed position to the pre-firing position until the piston returns to a piston pre-firing position post combustion.

A combustion-powered fastener-driving tool includes a tool housing, a power source associated with the housing and including a cylinder head, a cylinder and a piston reciprocating in the cylinder, a valve sleeve reciprocating relative to the cylinder, a chamber switch and a trigger switch; the cylinder head, the valve sleeve, the cylinder and the piston combining to define a combustion chamber, the closing of both switches required for initiating an ignition of the power source for driving piston down cylinder. A fan is disposed in the combustion chamber, and a control system includes a control program associated with the housing, connected to the power source, the chamber switch and the trigger switch, and configured for providing a designated ignition delay period after fuel is injected into the combustion chamber and when the chamber switch is closed, the delay period being variable as a function of monitored tool parameters.
