The tricycle includes a rear axle, rear wheels coupled to free ends of the rear axle, a rear seat, and a rear frame coupled to the rear axle and to the rear seat. A front frame includes a fork tube, and the front frame and the rear frame are detachably connectable to each other. The tricycle also includes a handlebar, and a fork coupled to the handle bar. The fork is rotatably coupled to the fork tube. A front wheel includes pedal cranks and is rotat...

A novel dual bicycle connecting kit for connecting two bicycles in a side-by-side relationship. The kit may comprise a fixed handle bar coupling assembly attached to the first bicycle; one or more frame coupling assemblies attached at one end to the first bicycle and attached at the other end to the second bicycle. Also, one or more steering coupling assemblies may be attached at one end to the first bicycle and attached at the other end to the second bicycle. Another feature of the kit is that ...

A recreational bicycle apparatus includes side-by-side, interconnected bicycles, each of which is independently geared so that each rider can pedal at a different pace. The steering systems of the bicycles are linked so that either driver can steer using conventional handlebars. The position of comfortable, straight backed seats can be adjusted to suit the user. The apparatus is equipped with a positive trim or levelling mechanism for simultaneously changing the cant of both bicycles when riding...

A foldable tandem bicycle employs three separate frames joined at concentric seat tubes. The frames have quick release clamps to lock the frames into an open rigid orientation. The center frame has several configurations, unisex one having a closed complete frame with one diagonal brace and a second one with a pair of diagonal braces to eliminate the need for a top tube. A third embodiment employs in-line intermediate members.

A multipassenger pedal vehicle comprising at least two rear drive assemblies, each having a conventional design and including a triangularly shaped frame, a rear wheel, a seat, and a pedal assembly. The rear drive assemblies are interconnected in a side-by-side, spaced apart, and aligned relationship by a plurality of laterally disposed connectors. A steering assembly, also having a conventional design and including a wheel mounted in a fork-shaped frame with handlebars, is positioned centrally ...

A pump supported from a wheeled trailer having a hitch connection with a tractor drawbar and a drive connection with the power take-off of the tractor with the pump including dual inlets enabling it to be backed into a ditch, sump, concrete canal, sewage lagoon, or the like. The hitch includes an elevated central portion defined by upwardly angulated portions rigidly connected at the center to facilitate the pump and its supporting frame and wheels being easily backed into and operated in relati...

A foldable tandem bicycle employs three separate frames joined at concentric seat tubes. The frames have quick release clamps to lock the frames into an open rigid orientation. The center frame has several configurations, male one having a closed complete frame with one diagonal brace and a female one with a pair of diagonal braces to eliminate the need for a top tube.

A bicycle sidecar includes a frame. A protective skin covers the frame. A wheel is connected to the frame. A connector system is used to attach the frame to a bicycle. A seat is and a grab bar are connected to the frame. A pedal assembly is mounted to the frame. A transmission system is connected to the pedal assembly. A pedal adapter assembly connects the transmission system to the bicycle.

A portable pump for displacing water having a frame supported by ground contacting wheels for transport, an elongated tubular conduit with an impeller mounted therein and a drive shaft with one end connected to the impeller and the other end having a non complex universal bearing joint for detachably coupling directly to a driving motor shaft of a farm tractor or other prime mover. The drive shaft exits the tubular conduit on the underside so that the angle between the driving motor shaft and im...
