Abstract: The disclosed toy may be used for capturing an intended toy victim within a snare net sufficiently large when opened to fit over and around at least part of the victim. A carrier, shaped as a monstrous insect or the like, may be used for holding the net open while stalking the victim, for positioning the net over and down around the victim, and for releasing the net when desired to snare the victim. The carrier may have a body and a plurality of legs depending from the body in an array to fit at least partially down and around the victim. Corresponding free ends of the legs have means for receiving and removably holding the snare net, to hold the same opened. The net may be elongated and generally tubular in shape, having a closed end and an open end. Flexible elastic means at the open net end, may be stretched to the holding means on the legs; and when released, may resiliently close the open net end against and relative to the victim.

Abstract: A method of repairing an end-of-car cushioning device for railroad cars is disclosed. The cushioning device is of the type having a piston and a shaft connected to the piston. In such devices, the shaft may become damaged with wear. In the disclosed method of repair, the old piston and shaft are removed from the cushioning device. The old shaft is substantially removed from the piston. The piston's true center is found, and a bore is cut through it. The bore is threaded, and an angled chamfer is cut in one end of the bore. A new shaft is provided with a threaded portion, the threads being adapted to mate with the threads of the bore. The shaft also has an angled chamfer adapted to mate with the bore's chamfer. The new shaft is connected to the old piston so that the threads engage and the chamfers abut.

Abstract: A self propelled toy vehicle provided with a self contained bridging assembly. A bridging assembly is provided which upon manual actuation is automatically positioned to be driven over by the toy vehicle as it climbs over an embankment or passes over a chasm. After the vehicle has passed over the bridging member, it is automatically returned to a rest position on top of the vehicle.

Abstract: An air turning vane assembly in which the vanes are attached to rail tabs by integral locking clips formed upon the rail tabs. The rail assembly is constructed from nestable rails having cutout portions to receive the tabs of similar rails to permit compact nesting. A locking tool has a cutting tooth which cuts a ribbon in a vane wall to form an integral locking clip for securing the vanes to the rails.

Abstract: A drawing machine having a frame for translatory movement upon a drawing surface. The frame defines an elongated, transverse interior opening. A plurality of template means are removably receivable within the interior opening. Each includes an aperture defining a shape which may be traced upon the drawing surface by the user. The template means may be repositioned along the transverse length of the elongated interior opening. Translatory movement of the drawing machine upon the drawing surface and guided movement of the template means along the interior opening permit the user to create varied patterns and pictures.

Abstract: A package seal particularly suited to pumps or other applications having a drive shaft which terminates internally of a housing at its connection to the impeller or fluid working element. In such an apparatus partial disassembly of the components provides access to the free end of the drive shaft. The package seal has an outer member adapted to be disposed coaxially on the rotatable shaft and pass through the housing bore. The outer member includes a mounting flange adapted to be secured in the interior of the housing and a cylindrical body adapted to extend axially along the rotatable shaft from the seal flange to the exterior of the housing. The cylindrical body houses the seal components which provide a fluid tight seal between the housing and shaft.

Abstract: A toy formed as a small vehicle which is propelled from a simulated explosive such as dynamite. The simulated dynamite is inserted in the rear of the toy. The toy vehicle is released from the simulated explosive by a cable attached to a plunger type detonator. The insertion of the simulated dynamite into the vehicle compresses a spring which drives the vehicle away from the simulated dynamite on actuation of a release mechanism.

Abstract: An apparatus and method utilizing pressurized air discharged through nozzles to segregate a mixture of elements having either different geometrical characteristics or different masses. The mixture is placed in a container having a conveyor track, and is forced to move along the track, across a primary nozzle which forms the mixture into a single layer. The mixture then moves across a blow-off nozzle which propels one set of elements off the track and out of the container while the other remains within the container. A two stage separation may be used to optimize efficiency.

Abstract: An all purpose railroad car for transporting trailers and containers, having an elongated frame adapted to be supported by wheel trucks, combined hitch and container bolster means adjacent one end of the car frame for selectively receiving and releasably retaining a trailer king pin and one end of a container, and means spaced from the combined hitch and container bolster means for selectively receiving and supporting the wheels of a trailer and the other end of a container. The car may be a light-weight skeletal frame including an elongated center sill, wheel trucks at opposite ends of the center sill supporting said center sill, each wheel truck including a single axle. Cushioning means may be provided between the combined hitch and container bolster means and the frame operable to oppose longitudinal movement of the lading relative to the frame.

Abstract: An elongated sheet of printed material for a roll stamp dispenser having formed flaps serving as driving sprockets and also having perforated score lines for tearing the stamp from the dispenser. A plurality of partially cut spaced apart flap groups formed of flaps along transverse lines mate with driving pins on the roll stamp dispenser. The flaps remain in tact with the stamp roll so as not to destroy the printed appearance of the stamp roll. Perforated transverse continuous score lines are formed at predetermined positions along the longitudinal length of the roll for use in separating adjacent sections of the roll as desired.

The offset unit also includes external support such as external auxiliary frame (45) affixed to the outside of the main frame between the main frame and the gear train.

Abstract: Improvements in sprinkler systems having fluid under pressure flowing therethrough and a sprinkler head with a pop-up nozzle actuated by fluid pressure. An impeller is actuated by the fluid flow to rotate the nozzle and thus rotate the spray of fluid therefrom. A transmission is disposed between the impeller and the nozzle for transmitting rotation of the impeller to the nozzle. The transmission is sealed off from the fluid passing through the system by a resilient expandable diaphragm at one end. A fluid pressure responsive seal is provided in the system in sealing engagement with the nozzle. The sealed-off portion of the transmission is completely filled with a lubricating medium which is free to selectively contract or expand against the diaphragm in response to varying ambient conditions encountered by the sprinkler head. The nozzle may also include means for varying the pattern of the sprayed fluid and may be comprised of molded plastic components which may be assembled together.
