  • Patent number: 4506698
    Abstract: A garden hose storage apparatus is particularly adapted for mounting on a substantially vertical surface and includes a side mount. The side mount has a base adapted for attachment to a substantially vertical surface and a cantilever journal is formed integral with the base. An elongated pipe is fixed in the cantilever journal and extends outwardly from the journal. A hose reel is rotatably mounted on the journal and has its axis of rotation substantially coincidental with the longitudinal axis of the pipe. An out tube is releasably connected to the pipe and has a connector adapted for connecting the out tube to a garden hose. A lock releasably connects the reel to the longitudinal pipe to retain the reel on the journal. Release of the lock allows the reel to be removed from the journal.

  • Patent number: 4483362
    Abstract: An apparatus for supplying fluid under pressure, such as compressed air, to movable using devices, includes a feed line having tap points spaced along it, with a tap valve at each tap point. A connection unit for connecting the feed line to the user is movable along the feed line and can receive fluid at any tap point. As the connection unit slides into place at the tap point, the tap valve automatically opens to supply fluid. Each valve has a rotary or slide-type valve member movable between open and closed positions, which is always exposed to equal fluid pressure all about it so as to require only a small force to actuate the valve. The valve member is tubular and open-ended and extends parallel to the feed line. Both mechanical and magnetic means for actuating the valve member are disclosed.

    Abstract: A take-up reel for storing and paying out an elongated flexible member such as a cable, rope, hose or the like features viscous damped rewind action which reduces shock loads on the hose and associated equipment. A viscous damper is coupled to the take-up reel assembly and limits the rewind velocity so that the hose can be released for free rewind without undergoing excessive shock. In a preferred embodiment, the viscous damping action is provided by a stator disc which is enclosed within an annular damper housing carried by the rotor of the take-up reel assembly.

  • Patent number: 4441522
    Abstract: A fluid swivel is described, of the type which includes an annular chamber formed at the interface between the stationary and rotatable parts of the swivel, which facilitates the passage of a pig through the chamber. A pig diverter device lies beside the outlet formed in one of the parts through which fluid normally exits the chamber, to divert a pig moving through the chamber into the outlet. The diverter device can include a projection lying on the downstream side of the outlet. The projection can extend radially only up to the interface between the two swivel parts, to facilitate disassembly of the swivel. The diverter device can also include a valving mechanism that can shut off fluid flow immediately downstream of the outlet, to direct the fluid stream and pig into the outlet, and the upstream end of the outlet can extend tangent to the chamber to facilitate pig entry therein.

  • Patent number: 4391298
    Abstract: A piggable fluid swivel comprising a first element on which a second element is rotatably mounted. Grooves in both the first and second elements align to form a continuous flow passage between the elements. Openings are provided through the first and second elements and into the flow passage whereby fluid can enter through one element, flow through at least a portion of the flow passage, and then exit through the other element. A flow barrier means similar to a gate valve is provided on one of the elements and includes a baffle plate that is extendable between an open position and a closed position. In an open position, the elements can be easily assembled and disassembled. In a closed position, the baffle plate blocks backflow in the fluid passage which allows pressure to build behind any pig that may become stuck in the flow passage to free the pig and carry it from the swivel. The swivel may be coaxially stacked to provide a multiline piggable fluid swivel.

  • Patent number: 4375823
    Abstract: In the coil end of a rotor of an electrical machine, the terminal ends emerging from different grooves and resting on different cylindrical surfaces must be electrically connected with each other and hydraulically with a water chamber. This is accomplished by distributors which include a connecting stud and two shanks which extend therefrom. The shanks have bores which extend at an acute angle into a bore on the connecting stud. This causes only very small flow resistance. The freedom that is gained in terms of choosing the desired shank lengths, and the freedom to choose the interval between the free shank endings, gives rise to a number of production advantages. Furthermore, the quality tests for checking the junction of the distributor pieces with the terminal endings of the windings are simplified.

  • Patent number: 4372341
    Abstract: A rotary switch valve, particularly for use in a vehicle where the operator may wish to face in either direction such as on a tractor where implements or attachments may be mounted on either the front or rear ends. The valve consists of at least two passageways for allowing passage of hydraulic fluid, which passageways pass through both a casing and a spool, relative rotational movement being allowed between them. Upon 180.degree. relative rotational movement, the passageways feed fluid from the outlet ports in a sense opposite to that when the spool and casing were in their original positions. The steering system of the vehicle, therefore, will continue to direct the vehicle in its normal sense.

The conduit is formed of split annular rings adapted to be mounted over a propeller shaft, the rings being interconnected to form passages for directing air pressure from the A-bracket through relative rotating seal members and into the body of the propeller. The disclosed interconnection of the annular rings permits substantial axial and bending movement of the propeller shaft without loss of air.
