  • Patent number: 4138897
    Abstract: A balanced crankshaft mechanism for the two piston Stirling engine which permits the use of a single crankpin and eliminates side forces on the pistons. A triangular yoke has connected to its respective apexes the connecting rods for each piston and the crankpin. One end of a rocking lever is connected to said yoke at a point between the points at which the connecting rods are attached. The other end of said rocking lever is connected to the base of the machine. As the crankpin rotates, the separate connecting rods and their respective pistons are moved with a phase relation appropriate for a two piston Stirling engine, and side forces are absorbed by the rocking lever, rather than by the pistons. A simple means of balancing the reciprocating inertial forces is described, which is also applicable to other types of Stirling engines.

  • Patent number: 4138004
    Abstract: Hydraulic controls in a transmission for engaging a clutch for the F-R, or forward or reverse, direction before a clutch for first, second, or third speed. Flow of hydraulic fluid to each direction clutch and to each speed clutch is by way of a reducing valve which modulates fluid pressure in controlled way by throttling the flow. After the power unit for the clutch for the F-R clutches and the power unit for the clutch for first, second or third speed are filled with fluid by the reducing valve, pressure in the power units is then slowly raised by the valve linearly toward its maximum; for this purpose the hydraulic controls are supplied by a single source of hydraulic fluid and operate therefrom to provide a pair of modulated pressure outputs which are maintained with varying differences throughout their range of operation, and which operate the selected one of the F-R clutches and the selected one of the first second or third clutches.

  • Patent number: 4137786
    Abstract: A belt-type speed change device having a pair of pulleys around which passes a belt. A side plate of each of the pulleys is axially movable relative to the other, fixed, side plate, thereby to provide for changes in transmission ratio. A rest position of the movable side plate of one of the pulleys, in embodiments described the driven pulley, is defined by a first abutment. The first abutment is movable between an operative position in which it is engageable by the movable side plate to define the rest position of the movable side plate and a retracted position in which the first abutment permits further axial movement of the movable side plate away from the fixed side plate to a retracted position as defined by a second or stop abutment, thereby to permit removal of the belt from the pulleys.

  • Patent number: 4137783
    Abstract: The invention relates to a device for converting a rotary movement into an oscillating movement frequently employed in agricultural implements, comprising a rotatable driving shaft, a fly-wheel rigidly secured thereto, an oscillatorily driven body adapted to oscillate about an axis crossing or intersecting the driving shaft axis and a coupling element pivoted to said body and journalled eccentrically in the fly-wheel; to adjusting in a simple manner the magnitude of the oscillating movement or the amplitude thereof, the device is adapted in that the bearing of the coupling element in the fly-wheel is arranged in a displaceable manner for varying the eccentricity and hence the amplitude of the oscillatory movement.

  • Patent number: 4136571
    Abstract: The disclosure embraces a manure disposal installation including an electric motor having a fixed stator and a rotor which is attached to a hollow cylinder on the interior of which is fixedly secured a threaded nut; a threaded shaft passes through the center of the cylinder that is fixed to the rotor whereby rotation of the rotor will effect linear translation of the shaft; to one end of the shaft is attached a coupling means for coupling the shaft to a manure shovel rod to which is secured a manure shovel; the shaft is provided adjacent its ends with non-threaded, reduced diameter portions so that in the event that the direction of rotation of the rotor, upon the shovel reaching its limit of travel, is not automatically changed, damage to the associated mechanisms will be avoided since the reduced diameter portion of the shaft will come into juxtaposition with the nut fixed on the hollow cylinder whereby further movement of the shaft is prevented.

  • Patent number: 4134306
    Abstract: A rotary actuator for converting reciprocating motion to rotary motion including a housing having spaced-apart end plates connected by guide rods. A bellows is provided having opposite sides one of which is connected to one of the end plates, the bellows being adapted to be connected to a source of fluid under pressure so that the bellows expands from a collapsed to an expanded position. A guide plate is provided movably mounted on the guide rods with the other bellows side being connected thereto. A rack and pinion assembly is provided mounted on the other end plate, the rack being connected to the guide plate so that expansion and contraction of the bellows causes linear movement of the rack thereby imparting rotary movement to the pinion. A spring acts between the guide plate and the other end plate thus resisting expansion of the bellows and returning it to the collapsed position upon the release of fluid pressure.

  • Patent number: 4134481
    Abstract: Back-pedal brake operator for multi-speed bicycles in which the brake operating action is obtained by turning the foot pedals rearwardly a short distance from any position which the pedals may occupy at the instant when the driver wishes to apply braking action, the braking operation being obtained without utilizing the sprocket chain to apply the braking force, and the brakes are automatically released without any "lock-up" effect when the driver starts pedaling forward in the normal manner. The back-pedal operators shown are directly associated with the sprocket assembly as a compact self-contained unit integrated therewith and can be installed as original equipment by bicycle manufacturers or can be retrofitted by bicycle shops or owners on existing multi-speed bicycles. The bicycle is permitted to be wheeled freely rearwardly without the brakes becoming applied.
