A fitting is provided for locating and securing a channel-shaped carpet edging cap along the bottom of a wall at a predetermined height above a floor or carpet surface. The fitting comprises an angle section base member and a cap-supporting member adjustably mounted on the base member so that an upper edge of the cap-supporting member can be adjusted to the required height of the cap. In use, the cap is supported on the upper edge of the cap-supporting member in contact with the wall and is secu...

Interchangeable internally gripping chucks for use in a machine applying non-rotative closures to containers, the machine having a multi-station rotary turret arrangement for receiving the containers from a feed conveyor. Each chuck is attached to a spindle in the rotary turret and includes spring loaded jaws for gripping a closure and seating it into or onto the upper portion of a container. The jaws are respectively biased radially outward by the spring loading means, and as the chuck descends...

An improved cap disc air clutch mechanism is provided, in which a pair of improved cap disc air clutch mechanisms will sense the torque between a cap and neck of a container and will allow cap tightening discs thereon to stop once the desired torque is reached and at the same time, allow the respective spindle shafts to continue to rotate. The improved cap disc air clutch mechanisms are adjustable to different torques by varying air pressure thereto, since the torque required for caps and contai...

An apparatus for mounting caps onto fluid containers in a predetermined particular orientation relative to the fluid containers. Caps are drawn from a source of caps and placed singly, in succession, on a cap seat which is in a particular known orientation. Each cap is taken, while on the cap seat, to a delivery position. During transfer to the delivery position, each cap is aligned into a known particular orientation. A device for picking up the caps takes each cap from the cap seat to a contai...

A capper for a printhead maintenance station is provided. The capper comprises a capping chamber sealingly engageable around a printhead; a constriction member positioned in the capper chamber; an air inlet defined in a wall of the capping chamber; and a vacuum aperture defined in a wall of the capping chamber. The constriction member divides the capper chamber into an air inlet channel and a vacuum channel into which the respective air inlet and vacuum aperture open. The constriction member als...

The invention concerns an apparatus for applying closures to containers. Each closure is carried to a respective container in a chuck of a closure holder mounted on a closure conveyor. The holder has an axially movable spindle which is yieldably moved from a retracted position to an extended position as the closure conveyor moves. The spindle may be selectively rotated while in extended position, by a pulley which is coupled to it by a clutch. The closures are applied to containers moving on a s...

This air operated plastic pail capper machine is designed to quickly and effectively push a cover onto a pail, while also pushing out any air that may be above the contents of the pail. Primarily, it consists of a base with rollers on top for easy alignment of a pail with a plate attached to a piston rod of an air cylinder, and the air cylinder is mounted to a sleeve attached to a post secured to the base of the machine. Palm operated valves are also employed to operate the machine.

This invention concerns a printhead capping mechanism for preventing evaporation of ink from a printhead when it is not in use. The invention has utility, for instance, in a color printer which uses a drop-on-demand inkjet printhead. The mechanism includes a cap fitted with an elastomeric seal to seal against the face of the printhead, and a sponge to catch drops ejected from the printhead during the nozzle cleaning cycle. The mechanism also includes an actuating structure operable to selectivel...

A heat seal capper head assembly for forming a closure and sealing a container with a heat seal cap having a heat shrinkable film includes an elongated housing having at one end adaptor means for releasably securing the assembly to the conventional filling apparatus for the container, while at the opposite end of the housing there is provided means for folding and heat sealing the heat seal cap to form a heat sealed closure having a central portion and a skirt portion. The folding means includes...

Apparatus and method for extinguishing oil well fires by plugging a wellhead pipe from which oil, gas and a fire flame front are emanating including centering and fluid ballasting a capper over the wellhead pipe, forcibly inserting the capper into the wellhead pipe to seal the wellhead pipe and introducing mud through the capper into the wellhead pipe to "kill" the fire. The apparatus includes the capper, fluid ballast and pressure exerting apparatus and plugging apparatus.
