Abstract: A removable gooseneck for detachably connecting a tractor and trailer utilizes an elongate beam member attached to the hitch of the tractor and having an upstanding frame member depending from a rear end of the beam member. A foot is pivotally mounted at a lower end of the upstanding frame member for engagement with a front end portion of the trailer. A guide pin and link arrangement detachably connects the foot at a front end to the trailer and a locking pin and bushing arrangement detachably connects the rear end of the foot to the trailer at a location spaced from the guide pin and link arrangement. A power fluid ram extends between an upper portion of the upstanding frame member and the foot to selectively cause the foot member to swing upwardly and tilt the trailer downwardly for detachment of the gooseneck from the trailer and swing the foot downwardly to tilt the trailer upwardly for drafting.

Abstract: Conditional exchanging of working fluid between plural fluid circuits (13A, 13B) having separate supply pumps (18A, 18B) is provided for without continuously bleeding fluid from the pump control pressure lines (21A, 21B). Each circuit (13A, 13B) has a pump control (19A, 19B) responsive to a control pressure, a plurality of fluid motors (14A, 15A, 16A, 14B, 15B, 16B), and a group of resolver valves (38A, 38B) which compare motor pressures and intercommunicate the pump control (19A, 19B) with the most highly pressurized motor (14A, 15A, 16A, 14B, 15B, 16B). At times when fluid from one circuit (13A, 13B) is being delivered to a motor (16A, 16B) of another circuit (13A, 13B), the pressure comparing function of the resolver group (38A, 38B) of the one circuit (13A, 13 B) is extended to include the motor (16A, 16B) of the other circuit (13A, 13B).

Abstract: A self loading multiple bale trailer comprises an elongated trailer frame with a belt conveyor extending from end to end and a lift fork for engagement at the lower periphery of a large round bale at the side of the trailer, for example, by forward motion of a tow vehicle. The lift fork is supported on a frame which is connected by an arm to a sleeve slidable on a verticle shaft and having an hydraulic cylinder for lifting the bale. The sleeve is also rotatable about a vertical axis to swing the lifted bale a half circle from the side of the trailer to a position over the conveyor for deposit thereon. The conveyor is operable to move the deposited bale to a desired position along the trailer, and may also be used to discharge the bale from the rear of the trailer or to reengage the lift fork with the bale. In an alternative form, the bale may be handled by a penetrating spike instead of lift fork legs, which spike may be utilized, in a quarter turn position, in unwinding the bale for feeding.

An additional slot is disposed in the shoulder and opens to the groove, has a ramp-like bottom, and a width different from that of the metering slot.

Abstract: A hydraulic system including a hydraulic pump, a hydraulic motor having at least one port and a hydraulic reservoir. A main spool valve is interposed between the motor and the pump and reservoir and has a spool shiftable between positions connecting the pump to the port, connecting the reservoir to the port, and blocking fluid flow to or from the port. A single combination check and flow control valve is interposed between the main spool valve and the port. A fluid responsive surface opens the combination valve to permit relatively free flow of fluid therethrough when the spool is in the first mentioned position thereof. A pressure responsive surface and a control valve provides for partial opening of the combination valve to meter fluid flow therethrough when the spool is in the second position thereof. A spring is operative to close the combination valve to prevent fluid flow therethrough when the spool is in the last mentioned position thereof.

Abstract: A supply or demand margin valve for use in hydraulic systems having at least one load provided with hydraulic fluid under pressure by a main pump, a pilot pump and at least one control valve for the load. The margin valve includes a valve body having a bore with a spool reciprocally received within the bore. A first port in the body extends to the bore and is adapted to be connected to the pilot pump. A second port in the body extends to the bore and spaced in relation to the first port and is adapted to be connected to a component of a hydraulic system other than a pilot pump. A spring is disposed in the valve body for applying a biasing force to the spool to urge the spool in one direction and a third port is in fluid communication with the pressure responsive surface and is adapted to be connected to a main pump so as to apply a force to the spool to urge the spool in the same direction as the spring.

Abstract: A check valve comprises a housing defining a valve seat thereon and a valve member reciprocally mounted in the housing to normally engage the seat for blocking fluid flow therepast. Two pairs of split retaining members are mounted in axially spaced relationship on a stem of the valve member and are expanded axially thereon by a compression coil spring for biasing the valve member to its closed position. A stop member is secured on an end of the stem of the valve member to prevent movement of one pair of the retaining members therepast. A slot is formed axially through the stop member and extends partially in the stem of the valve member to expose an end of the spring. In assembling the valve, a tool is inserted into the slot to compress the spring whereby the one pair of retaining members may be mounted on the valve member, between the spring and the stop member.

Abstract: A construction vehicle has a work implement, such as a bucket-carrying boom, pivotally mounted thereon to be raised and lowered by one or more double-acting hydraulic cylinders. A directional control valve is conditioned to selectively communicate pressurized fluid to the rod end of each cylinder, for example, through a check valve. When the fluid pressure in the rod end of the cylinder exceeds a predetermined level, a pilot signal will be communicated to a modulating valve which will open to closely control and modulate the flow of the fluid exhausted from the head end of the cylinder. A pilot relief valve is interconnected between the head end of the cylinder and the modulating valve to cooperate therewith to relieve excessive fluid pressures. The above system is duplicated for selectively pressurizing the head end of the cylinder and for exhausting the rod end thereof.

Abstract: Pressurized fluid is supplied to fluid-driven mechanisms by a variable displacement supply pump through a check valve and a flow control valve. A compensator receiving a pressure feedback signal from the control valve side of the check valve increases pump displacement in response to a pressure signal drop and decreases pump displacement in response to a rise in the signal pressure to compensate for variations in demand. Part of the supply pump output is used to drive a small fluid motor which turns a small pressure signal-amplifying pump connected in parallel with the check valve. The check valve opens to transmit the variable displacement pump output to the driven mechanisms when the control valve is opened.
