Abstract: In a block for a rope or sheet: a pulley over which the rope moves, an eccentric cam which is pivotable to selectively clamp or release the rope against the pulley and a pivotably lever to which the cam is connected such that motion of the lever pivots the cam between its clamping and releasing position; bearing means to enable pivoting of the lever away from the cam clamping position; a spring to at least return the cam to its clamping position.

Abstract: An internal tire lubricant which minimizes or prevents injury to a pneumatic tire when it runs flat, and which also assists in sealing small punctures, consists of a mixture of liquid or easily fusible materials, one of which is a partially crystalline solid olefine polymer, and another of which is an essentially noncrystalline liquid or solid hydrocarbon or analogous material.

Abstract: In a track tamping machine, opposed pivotally mounted tamping arms are oscillated by respective single acting hydraulic cylinders controlled by one or more hydraulic duplex rotary distributing valves. Fluid supply and return lines for each piston assembly are connected to a source of pressurized hydraulic fluid by way of a respective rotary valve. Each valve has a stationary ported shell which receives a rotary cylindrical spool having a pair of axially displaced supply and return throughports which alternately register with supply and return line ports in the shell to open and close the connections between the oscillating cylinder and the supply and return lines. Such oscillating cylinders are useful in controlling the vibration of the tamper arms in a track tamper unit.

Abstract: A cargo control restraint shield for use in the container of a trailer truck for weather protection of the cargo, compartmentalization of the cargo and for restraining the cargo and holding it in place. Cables are secured within the container at the upper and lower corners thereof so as to extend from the rear to the front of the container in a taut fashion. Clamps are received on the cables and are movable thereon from front to rear of the container. A flexible rectangular sheet of vinyl material has hooks mounted at the four corners thereof. Two of the hooks are secured to the clamps and two are secured to the lower cables. The clamps lock on the cables against movement of the vinyl sheet away from the cargo but may be released by long levers which hang downwardly from the cables. Long handles are attached to the hooks which are secured to the clamps and may be used to lift the hooks off of the clamps or to place the hooks on the clamps.

Abstract: A motorized shovel comprises a carriage which may be provided with wheels to enable it to negotiate the ground and is formed with an upright pole carrying an arm adapted to overhang the operator. The arm is swingable about a vertical axis to follow the movements of an operator and carries a pneumatic-motor-driven winch drum adapted to pay out and retract a cable depending from the free end of the arm. The cable is anchored to a shovel unit whose handle is provided with a handle bar adapted to be gripped by the operator. Controls on the handle bar regulate the operation of the winch and of a pneumatic vibrator interposed between the handle and the shovel blade. Flexible conduits run along the downwardly extending stretch of the cable to connect the pneumatic controls to the winch.

Abstract: A transfer mechanism for dumping the contents of a shipping drum into an open-topped mixing vessel has a rotatable frame spaced above the support surface on which the vessel and drum can be rolled about, the frame having an annular plate and hooks on one side of the plate for lifting and holding the vessel against that side of the plate and a fork on the opposite side of the plate for lifting and holding a drum against that opposite side of the plate. By first picking up the vessel, rotating the frame 180.degree. to turn the vessel upside down, picking up the drum, and rotating the frame to its original position with the drum upside down, the drum contents are transferred to the vessel through the annular plate in a confined manner. A suction chamber is mounted on the transfer mechanism to withdraw any remaining loose material or dust from the shipping drum before it is removed from the transfer mechanism.

Abstract: The invention comprises improvements to an automatic bale wagon of the type having a load table for receiving bales thereon and being pivotable between a bale-receiving position and a bale-unloading position for transferring bales loaded thereon onto a further component. The invention enables to use such bale wagons on slopes transverse to the longitudinal axis thereof and comprises retractable bale-retaining means associated with the load table and operable to maintain bales deposited on the load table in a predetermined position when moving from its bale-receiving position to its bale-unloading position.

Abstract: An arrangement of a detachable ballast weight, especially at the front side of an agricultural motor vehicle, which includes a holding device connected to the vehicle transverse to the driving direction of the latter for receiving the ballast weight. The ballast weight is adapted non-rotatably to be suspended on the holding device by catching behind the holding device or a protrusion thereof and is adapted to be locked in its suspended position by means of a locking shaft when the latter extends transverse to the ballast weight and behind a portion thereof. The two ends of the locking shaft are by means of radially engaging clamping elements detachably connectable to the holding device or to a part connected thereto.

Abstract: An automated refuse container discharge station is disclosed in which a refuse container is emptied such that its volume decreases as an essentially constant function of time. The unloading station includes a support assembly on which a carriage assembly is adapted for longitudinally sliding motion. The carriage assembly includes container opening apparatus at one end and container discharging apparatus at the other end. The carriage assembly also includes apparatus for unlatching a container tailgate portion and releasably securing the container to the carriage. A hydraulic cylinder advances the carriage assembly with respect to the support assembly and hydraulically damps movement of the carriage and container at the end of the advancing stroke. The carriage assembly includes an hydraulic discharge cylinder which may be intermittently advanced into the container. Part of the discharge cylinder is supported by guides carried by the carriage and aligned guides carried by the container.

Abstract: A lock for a railway hopper car gate in which a hopper outlet chute defines a discharge opening with a siding platelike gate operating in the opening. An undercarriage structure having a pair of spaced side frames supports the gate for sliding movement relative the opening. An elongated lock shaft extends between and projects through guide slots formed in both side frames with one of the side frames also being formed with a lock hole. A U-shaped handle is fixed to each end of the lock shaft with each handle having a return leg supported for transverse and pivoting movement relative the side frames. A latching shoulder is fixed to the elongated lock shaft and one of the guide slots is formed with a latching notch. Transverse movement of the lock shaft by operation of either handle effects an engagement of one of the handle return legs into the frame hole to thereby lock the gate.

Abstract: A pedestal liner for railroad trucks is disclosed in which the liner is not bolted to the pedestal leg, but instead is allowed to "float" -- that is, to move relative both to the journal box and to the pedestal leg.

Abstract: An improved load moment sensing system for a lift truck having tilt and lift cylinders for tilting a mast and lifting a carriage on the mast, respectively. A sensor is provided for sensing the load moment placed on the frame and a sensor is provided for determining when the carriage is elevated on the mast. A logic system is responsive to the sensors for preventing actuation of the tilt and lift cylinders simultaneously when an overload is sensed while allowing rearward tilting only when an overload has been sensed and when the carriage is elevated. The system also prevents tilting forwardly when an overload has been sensed and when the carriage is elevated. The system also allows tilting forwardly when an overload has been sensed and the carriage is not elevated.
