Abstract: A hand-held tool has cutter blades actuated by a power wedge on a piston rod in an hydraulic cylinder. The hydraulic cylinder is powered by a compressed air supply through stationary apparatus containing an air-hydraulic pressure intensifier apart from the tool and connected therewith through a hydraulic line. The power wedge has inclined ramps at relatively steep angles of inclination to start closing of the blades quickly, and ramps at less steep angles to increase the force applied to the blades in cutting. An adjusting wedge stops the advance of the power wedge so that the blades do not strike each other. The tool may have an elongated rear extension with a pistol grip handle.

Abstract: This method of electric welding metal band ends together comprises a fusion cycle with the introduction of inert gas, a cooling cycle with the introduction of cooling air, and an annealing cycle. The method is carried out in a fusion head having grippers to manipulate the band ends, and a control system for the grippers, inert gas, cooling air, welding and annealing currents and timing functions.

Abstract: A bale binding machine for waste material has a bale encircling guide track for a band to bind the bale wherein the bottom portion of the guide track under the bale is provided with a pair of deflectors to intercept contaminating liquids and solids falling from the bale and prevent contamination of the guide track.

Abstract: In the illustrated embodiments, with a bale of material compressed between upper and lower press platens an end binder moves toward one end of the bale and a back track moves toward the opposite end to apply a loop of strap around the top, bottom and ends of the bale. Two side binders move from station to station along opposite sides of the bale to apply loops of strap around the top, bottom and sides of the bale at two strap positions at each station. Each side binder has a strapping section movable toward and away from the adjacent side of the bale. Strap guide tracks on the press platens are provided with covers which confine the straps during their feed movements and prevent premature release from the tracks.

Abstract: An elongated lift frame, lifted and moved by a crane, has a plurality of transverse spreader bars which may be shifted to different positions along the frame. The spreader bars have extensions in their ends equipped with supports for load hooks. A latch pin at each end of each spreader bar secures its extension in extended or retracted position and secures the spreader bar in a selected position on the lift frame.

Abstract: The lifting of a load moves a piston to pump a charge of air into a small compressed air reservoir above a load hook. A remote control radio signal opens a valve to transmit the air pressure to the load hook causing the hook to release itself from its load. The device may be incorporated in a self contained module associated with a single load hook or it may be adapted to a lifting frame having a plurality of releasable load hooks. Also, the device may be arranged to produce the pumping stroke of the piston by lowering the lifting frame down on top of the load as the load is lowered onto a support.

Abstract: Starting from a loading position, a door carriage moves a door sideways between a pair of saws to trim the ends of the door. Then the carriage remains stationary while a pair of planer heads move across the carriage to trim the side edges of the door. Finally, in a lower path of travel, the carriage returns to its loading position for unloading the door, with the door passing with clearance under the saws. During these operations the door is secured by a vacuum table on the carriage.

Abstract: A lifting hook has a spring biased safety latch to close the gap between the shank and the point of the hook. The hook is manipulated by a bent handle on the back side of the shank. A latch release cable extends along the handle in spaced relation thereto in the manner of a bow string. An operator can grasp the handle alone to manipulate the hook without releasing the latch or the cable can be included in the grasp when it is desired to release the latch.

Abstract: The entire table frame is a tank. The upper portion of the tank provides a working area and the lower portion forms a closed water flow control chamber. Removable gratings in the upper portion underlie support rails which support steel plates to be cut into desired shapes by an automatic profile burning head or a gang of such burning heads. The introduction of compressed air into the lower chamber displaces water into the upper section to submerge the removable grating. The water subdues the noise and smoke of the burning operation, cools the plates being burned, thus reducing distortion and catches the slag produced. Small pieces of metal falling off the plate being cut are cooled by the water and retained on the gratings. Release of air pressure from the lower chamber allows the water in the upper portion to return quickly to the lower chamber for convienent removal of the metal pieces from the gratings.
