A cycle, for example a bicycle, comprises a frame, a crossbar vertically pivotally mounted to the frame, a saddle fixed to the crossbar, a crank rotatably mounted on the frame, a mechanism for transmitting rotation of the crank to a drive wheel of the cycle, pedals rotatably provided on the crank for effecting rotation of the crank and a force transmission member for transmitting a force from the saddle to the crank, the force transmission member being pivoted to the crossbar for vertical moveme...

The crankset (1) includes two cranks (2) that extend in opposite directions on both sides of a crankset shaft (3), whereby each crank (2) is connected to the crankset shaft (3) at one of its ends and has, at its opposite end, a housing (4) that can accommodate a free end of a pedal shaft (5) by defining a distance between centers (L) between the crankset shaft (3) and the pedal shaft (5). The housing (4) is combined with elements (11, 12) for securing the pedal shaft (5) inside the housing (4). ...

A combined cycle wherein part of the gas turbine exhaust gas stream is recycled to the gas turbine and the remainder of the gas turbine exhaust gas stream is expelled from the cycle. The power output of the combined cycle is increased by increasing fraction of gas turbine exhaust gas that is recycled to the gas turbine and the power output of the combined cycle is reduced by reducing the fraction of gas turbine exhaust gas that is recycled to the gas turbine.

A light-reflective attachment to the spokes of a cycle wheel, formed for lug attachment where adjacent spokes cross relatively near the hub; to reflect light principally in the direction the wheel travels, and alternatively additionally at right angles thereto.

A seat structure for ready attachment and detachment from the luggage carriers of cycle type vicles providing a padded seat and back rest maintained in operative relation by strap means detachably secured to ring connectors disposed at the forward corners of the seat and encircling the back rest adjacent its upper edge so as to be inclined downwardly and forwardly past the thighs of the occupant to provide centering side support. The seat structure be comprised of a one piece foam rubber padding...

A cycle saddle comprising a baseplate and an insert, and a cover, a saddle post bracket attached to said insert by means of a pair of struck up generally cylindrical members like hollow rivets extending through commensurate apertures in the insert, said members being peened over on the interior of the insert in the areas adjacent the apertures.

A separate stand for a bicycle comprising an elongated member, having a transverse hook at one end thereof, a bent out leg, at the opposite end, and a crank housing offset intermediate the ends of the member, and a stiffening member secured to the elongated member adjacent the hook and also adjacent the bend of the leg, said stiffening member also including a like crank housing supporting offset, and an appositely bent leg.

This invention relates to cycle exercisers and is particularly applicable to such exercisers that either alternatively or simultaneously exercise the muscles of the legs and lower torso and muscles of the arms and upper torso. Arm levers for propelling the energy absorbing wheel of a cycle exerciser, do so by acting on crank arms through rotating slidable bearing means operating in slots in the arm levers; the crank arms are connected to a second drive shaft that is linked to the wheel by chain ...

A cycle exerciser having a one-way sprocket and a pair of one-way pinions disposed on a compound shaft. The one-way sprocket is rotated by a pedaling mechanism through a chain. The one-way pinions are respectively rotated by a pair of lever arms through a respective toothed element and a connecting mechanism. The toothed element engages and rotates the one-way pinion. The connecting mechanism comprises a substantially cylindrical swivel block and a torsional spring. The swivel block has a rim po...

A system for air conditioning and generating electrical power including a fuel-fired internal combustion engine, an electrical motor/generator, and a vapor compressor/expander all interconnected. The vapor compressor/expander driven by the engine operates in one mode with an evaporator and a condenser in a generally conventional refrigeration cycle. In an alternative mode, the vapor compressor/expander is operated in reverse by refrigerant boiled in the evaporator by the rejected heat of the eng...
