Abstract: At a power line discontinuous portion of a power-and-free trolley conveyor, a carrier is transferred from a carrier entering first power line to a second power line by being pushed by a following pusher dog from behind. The following pusher dog is restrained from disengaging from the rear free trolley by at least one endless free chain positioned immediately above and parallel to the path of the pusher dog. A pair of endless free chains can be used with the chains being reeved around sprockets to be free movable along with the engaged pusher dog, thereby avoiding wear on the pusher dog side projections. The loop of the chains extend for a distance sufficient for the front free trolley of the carrier to cross the powerline discontinuous portion of the conveyor.

Abstract: A high-speed switch machine for actuating railroad switch points. The machine has an electric motor which drives a hydraulic pump. The pump supplies pressure fluid to a hydraulic cylinder adapted to move the switch points from an initial to a second limit position. A four-way, two-position hydraulic control valve directs fluid to the cylinder such that the cylinder automatically operates in an extension and retraction cycle. The uni-directional motor and two-position control valve minimize response times of the actuating components so that the switch points are thrown in a short time period.

Abstract: A railway car coupler includes a shank, a head connected to a head end portion of the shank, a knuckle pivoted to the head having closed and open positions, and a lock axially movable within a chamber formed in the shank between a knuckle engaged position for maintaining the knuckle in the closed position and a knuckle disengaged position for enabling the knuckle to be pivoted to the open position. A thrower is pivotally connected to the lock and has an arm disposed to one side of the pivot for engaging the knuckle to rotate the knuckle to its open position. An actuating mechanism is connected to the thrower-lock assembly and is axially movable within the chamber. The actuating mechanism functions to axially move the lock towards its knuckle disengaged position, with continued movement of the actuating mechanism in the same direction pivoting the thrower and consequentially the knuckle to its open position after the lock has obtained its knuckle disengaged position.

The system can be readily assembled and disassembled and is capable of reducing vibration and noise transmitted from the truck to the car body.

Abstract: In accordance with the present invention a lock block link 34 has a first end 36 connected to a trailer hitch bumper block 22 and a second end 40 which engages a lock block 46 which holds the hitch jaws 16 in closed position. The lock block link 34 is supported by an operating shaft link 54 extending from a manual operating shaft 50 extending to the side of the hitch. When the bumper block 22 is engaged by a tractor, the bumper block rotates about pins 30 connecting the bumper block to the hitch head 10. This rotation moves the lock block link 34 and in turn the lock block 46 rearwardly, which allows the jaws 16 to rotate to open position to allow exit of the trailer king pin. A lost motion connection 31 is provided in the connection between the first end of the lock block link and the bumper block to allow the lock block link 34 to move relative to the bumper block when the lock block 46 is moved rearwardly manually by the operating shaft.
