Abstract: A mounting system for one or more traverse cylinders of a die cast machine positions the cylinders behind the movable platen on a side out of the die area between the platens. A horizontally extending cylinder support bar is mounted between the ends of the lower tie bars. A traverse cylinder is mounted between the support bar and movable platen. In another embodiment, vertically extending cylinder support bars are mounted to the lower and upper tie bars on each side of the machine, with the lower ends being fixedly secured to the lower tie bars and the upper ends detachably secured to the upper tie bars. The traverse cylinders are mounted between the support bars and the movable platen.

Abstract: A vertical die cast apparatus having a novel docking/shot assembly in which the docking and docking cylinder and shot cylinder are constructed in one compound cylinder. A novel construction for supporting the docking/shot assembly is also provided.

Abstract: A metal die casting machine having a safety bar mechanism for cushioning the stopping action of a movable platen when it is stopped prior to reaching the closed position of the dies. One embodiment provides a two-part bar connected together by a cushioning means. A second embodiment mounts a cushioning means on one of the platens, preferably the movable platen.

Abstract: A system and machine for squaring tie bars for die casting machines in which a detector means is provided for each of the tie bar nuts for separately and individually detecting the relative positions of the tie bar nuts of each of the tie rods whereby when the machine is originally squared by adjusting the adjustable means, the original squared positions of the nuts are detected and after operation of the machine it can be resquarded by adjusting said adjustable means to adjust said tie bar nuts back to their original squared positions. This adjustment is automatically accomplished through a logic circuit which controls the adjustment of the tie bar nuts.

Abstract: A clamping device used for mounting die sections on machine platens, the device including a support carriage slidably mounted on the platen and having a clamp arm thereon. Means is provided for advancing and withdrawing the carriage from a die section on the platen and for moving the engaging end of the clamp arm toward and away from the platen, the carriage and clamp arm being activated from the periphery of the platen. Preferably, a camming assembly is engaged with an advancement screw and is slidably mounted on the platen to shift with the carriage. The camming assembly and the carriage are biased apart, but converge when the carriage contacts the edge of the die section in order to cam the clamp arm onto the die section.

Abstract: An oil filter is disclosed as having a filter enclosure provided with oil inlet and outlet ports adapted for communication with the oil circulating system of an associated oil lubricated engine. Disposed within the enclosure is a filter element fabricated of any suitable filtering media. In addition to the filter element, a body of an oil soluble, relatively solid polymer having oil additives compounded therein is disposed within the enclosure. The polymer body is located within the enclosure so as to be in an area where minimum oil flow occurs, i.e. in a relatively non-turbulent oil flow area, which results in the polymer dissolving at a relatively uniform or linear rate so as to prevent undesirable concentrations of the additives during the effective service life of the filter.

Abstract: A vehicle leveling system comprising at least one leveling strut having a pressurizable chamber and a height sensing and controlling mechanism located directly on the strut, the height sensing and controlling mechanism being operable to control the internal pressure within the chamber without requiring any mechanical connection or engagement of the component parts thereof which are associated with the sprung and unsprung portions of the vehicle. In one embodiment of the invention, the height sensing and controlling mechanism includes a light source and a light responsive device for controlling operation of an electrically energized compressor, while in another embodiment of the present invention, the height sensing and controlling mechanism includes a proximity switch arrangement.

Abstract: A vehicle leveling system adapted for varying the attitude between the sprung and unsprung portions of an automotive vehicle, the system including a pair of leveling struts interposed between the vehicle portions and operable in response to an increase in fluid pressure supplied thereto to elevate the sprung portion of the vehicle relative to the unsprung portion thereof, an operable in response to a decrease in fluid pressure supplied thereto to lower the sprung portion of the vehicle relative to the unsprung portion thereof, an electrically energized means for supplying pressurized fluid to the struts and fluid circuit means communicating a pressurized fluid to the struts, and a control device located within the interior of the associated vehicle and operable by the vehicle driver, with the control means including first and second control elements, the first control element including electric switch for opening and closing an electrical circuit communicating a source of electrical energy with the fluid pres

Abstract: A hydraulic clutch system comprising a first piston and cylinder assembly including a piston rod for causing a first piston to move within a first enclosure in response to actuation of a vehicle clutch pedal or the like, a second piston cylinder assembly including a second piston movable within a second enclosure from a non-actuated position to an actuated position to operate a vehicle clutch mechanism, a fluid circuit including a hydraulic conduit communicating fluid from one end of the first enclosure to the second enclosure and operable to bias the second piston from the non-actuated position toward the actuated position, a fluid reservoir communicable with the fluid circuit, and a valve operative in response to preselected movement of one of the pistons within the associated of the enclosures for communicating the reservoir with the conduit.
