Abstract: A pallet truck hydraulic jack has a base plate mounting a lift cylinder with a reciprocal piston or lift rod and a pump cylinder with a reciprocal pump piston. A cartridge type directional control valve assembly within the base plate controls the flow of pressurized hydraulic fluid in respective manifold passages so that manual actuation of the pump effects a quick lift of the frame when it is unloaded, effects an additional application of lifting force through the lift cylinder when the frame is loaded, bypasses pressurized hydraulic fluid to the reservoir when the frame is overloaded, and provides a release of pressurized hydraulic fluid from the pump cylinder and the lift plunger and returns it to the reservoir for lowering the frame and forks.

Abstract: A cartridge type directional control valve assembly includes an elongated housing having a bore and a plug threaded in the outer end of the housing adjacent the bore. A changeover, spring biased piston forming a load senser or pressure sensor is provided in the bore with a sealing O ring therebetween. A coil spring is interposed between the plug and the changeover piston. The plug has a vent passage for venting the chamber of the coil spring. A valve retaining screw located in the housing, is centrally apertured and loosely receives the shank of the cone or flow control valve. A coil spring is nested within the valve retaining screw and bears against the flow control valve which is normally seated with respect to a central aperture within the cone valve insert seat. A floating ball check valve is nested within the cartridge assembly and is axially aligned with and opposite from the flow control valve. The control valve and ball check valve control flow across their respective valve seats.

Abstract: A modular drum rack for storing and stacking drums. Two, three, four, or more laterally adjacent modules may be assembled together in a unit, to accommodate an equal number of drums in a single tier. Subsequent tiers can be stacked upon one another to form a drum stacking rack. The modules include openings for receiving fork truck tines to allow the units to be moved by a fork truck. Openings are provided on four sides of the units to permit handling from all directions. Two sets of openings are provided on the front and back of the unit to provide a balanced lift point for the unit with either an even number of drums or an odd number of drums. When the units are empty they are adapted to be interlocked with one another to reduce space requirements for return shipment.

Abstract: A cylinder assembly comprises a cylinder having a bore, a bearing therein and an extension bore. A head on the cylinder removably mounts and retains a gland assembly including a piston rod seal and wiper. A piston rod is reciprocally mounted within the bore and bearing and at its outer end mounts a stop plate assembly engageable with the cylinder head. The stop plate assembly is removable from the piston rod which is retractable into the extension bore, the outer end of the piston rod being inward of the wiper and seal, to permit removal and replacement of the seal and wiper. The method of replacing the seal and wiper from a cylinder assembly without disassembling the assembly or disconnecting the assembly from its support includes the steps of removing the stop plate assembly from the rod, retracting the rod into the bore extension until the front end of the rod clears the wiper and seal and removing and replacing the seal and wiper.

Abstract: An apparatus for transporting, cutting and dispensing heavy web sheet material such as cardboard, plastic film and the like, while in roll form. The apparatus includes a manually wheelable frame that can be selectively raised and lowered by a retractable handle at its rearward end to support the frame on a pair of front wheels for transporting the roll to the jobsite. Lowering the apparatus onto fixed rear legs supports the frame in a rest position for cutting and dispensing the sheet material. The frame has upright front and rear standards mounted in asymmetrical opposed relation on one side of the longitudinal center line of the frame. Thus, the roll is readily mounted in a stabilizing manner substantially along the frame center line by means of its roll axle shaft being supported on the inboard side of the standards.

A stop plate is mounted on and extends laterally outward of each jaw and is engageable with the support plate when the jaws are in a horizontal position for holding the jaws to operatively clamp a drum therebetween.

Abstract: A strip curtain door is adapted for positioning across a door opening having a header with a curtain rod spanning the opening at the top thereof. Hanger brackets support the rod and are secured to the header. A series of spaced opposed pairs of arcuate clips are loosely mounted upon the rod, each clip having a depending finger. A series of upright flat flexible strips of plastic material have their adjacent edges overlapped, extend across the opening over the height thereof with upper portions of each strip projected between a plurality of the pairs of clips. A fastener extends between the fingers of each pair of clips and through the strips whereby the fingers of the clips compressively engage and support the strips. In a modification, one finger of each pair of clips has a transverse dimple, with the other finger having an opposing transverse hole therethrough. Securing of the clips together forms a dimple in the strip which is projected into the finger hole for interlock therewith.
