Abstract: A trash compactor using a dolly as a receptacle for the trash to be compacted. The dolly is normally spring supported ready for movement into and out of the compactor, but when in the compactor and subjected to compacting pressure, the dolly is pressed downwardly, upon the beams of the main compactor frame which then takes the full compacting pressures.A novel construction of the dolly and compactor floor of the main frame makes such transfer of load possible. The compacting pressure is developed by four hydraulic cylinders, all of which are mounted on a common plate. The rod ends of the two center cylinders are connected to the top member of the main frame and the cylinder ends are connected to the common plate. The rod ends of the remaining two cylinders are connected to the main compacting plate with the cylinder ends mounted on the common plate. With the four cylinders mounted in this manner, twice the movement of the compacting ram is obtained.
Abstract: An improved motor Speed Actuated Vehicle Bumper wherein a cam and linkage arrangement combined with a spring is provided to restrain an inward movement of a bumper under collision conditions. The restraint increases as the speed of the vehicle on which it is installed so that its effectiveness is substantially constant over a range of vehicle speeds. The present improvement utilizes the speed responsive restraint, but in addition, it provides means for gradually extending the bumper in accordance with the speed of the vehicle. Thus, in addition to increasing the restraint with vehicle speed, the travel of the bumper is also increased with speed thereby dissipating the force of a collision over a greater travel of the bumper.
Abstract: A tape container and dispensing apparatus formed of plastic material including means for advancing the tape to dispense a strip of any desired length and integrally formed shearing means to provide scissors-like shearing action to sever the tape strip.
Abstract: Disclosed is a circuit for automatically turning off the lights of a vehicle after the ignition switch is turned off. A delay in the turning off of the lights is produced with the aid of a thermally responsive switch in series with the light switch. The light switch is initially in series with the ignition switch through the thermally responsive switch. The heat source of the thermally responsive switch is shut off with the ignition so that when the ignition switch is turned off, the heat source is deenergized and the bimetallic switch controlled thereby changes its shape to disconnect the light switch from the car battery. The heat source may be an electric heating element, or it may be some part of the vehicle power plant such as the exhaust pipe.
Abstract: A segmented packing for a ship's propeller shaft at a bulkhead in the ship's hold to prevent water in one ship's compartment from passing through the propeller shaft opening in a bulkhead to an adjacent compartment. The seal is normally held out of contact with the propeller shaft by equally spaced pins. The pins have grooves into which the seal segments are forced by encircling garter springs when the pins are normally pushed axially to apply the packing. The pins can be pushed from either side of the bulkhead so that the operator need not enter the flooded compartment to make the packing effective. The packing can be cocked again after use by operating a threaded jack for each segment and then retracting the pins to their initial position in which the packing is held out of contact with the shaft.
Abstract: The invention disclosed is a composite ring made of press-fitted parts and method of assembling concentric articles having an interference fit, the inner one of which has a surface of a granular material such as ceramic, the method eliminating the customary heat shrinking step by which the outer one, usually of metal, is heated and expanded over the inner one and then cooled to shrink it tightly over the inner one. According to the method disclosed, the ceramic surface is coated with a polyetetrafluoroethylene lubricant and then pressed into the outer one without the use of heat. A mating ring for rotary mechanical end face seals, wherein the mating ring is formed of a ceramic ring pressed into a metal supporting stamping, is also disclosed.
