| 7267639 | Compound bicycle exercising device A compound bicycle exercising device includes two foot pedals rotatably attached to a base, for being operated by users, two handle stems pivotally attached to the base, for being rotated by the users, and two rotary members secured to each handle stem. A spindle is... | 09/11/2007 |
| 6789439 | Reciprocal force outputting mechanism A reciprocal force outputting mechanism having a body having a slide slot that contains a slide block, thereby providing for the linear, reciprocal movement of the slide block within the slide slot. The slide block has an elongated opening formed centrally and a row... | 09/14/2004 |
| 5992253 | Method and apparatus for converting reciprocating motion to single direction rotational motion An apparatus for converting reciprocating motion to single direction rotational motion that includes a frame, a shaft supported by the frame for rotation relative to the frame, a first one-way clutch mounted on the shaft, a first pinion mounted on the fir... | 11/30/1999 |
| 5655404 | Mechanism for converting reciprocal movement A mechanism of converting a reciprocal movement into a rotary movement comprises a coulisse and a toothed unit cooperating with one another, the coulisse being shaped so that conversion of the reciprocal movement to rotary movement is performed in a seque... | 08/12/1997 |
| 4941396 | Reciprocating double-ended piston The present invention relates to a reciprocating engine which has an improved reciprocating double ended piston which substantially reduces the size and weight of piston components. The double ended piston comprises a center portion between the two end po... | 07/17/1990 |
| 4912995 | Thrust to torque converter, particularly for coupling a reciprocating shaft to a rotary electrical generator or the like A rotary-to-linear mechanical motion converter has a housing attachable to a drive engine, an input shaft reciprocable to the housing and coupled directly or through a gear arrangement to a reciprocating output shaft of the drive engine, a first drive tra... | 04/03/1990 |
| 4861055 | Drive mechanism A drive mechanism for a human-powered vehicle is disclosed. The vehicle has a frame, plural wheels and linear motion generating mechanism, which is operable by a human being, for generating substantially linear, oscillating motion. A motion converting dev... | 08/29/1989 |
| 4475412 | Infinite speed power transmission with shiftable gear plates An infinite speed transmission having aligned input and output shafts with the input shaft driving a pair of eccentrics each of which oscillates an arm which in turn drives a gear plate housing in a rectilinear manner. Each gear plate housing slidably car... | 10/09/1984 |
| 4408578 | Piston engine as a combustion engine or as a compressor with opposed cylinders A piston engine in which opposedly working pistons are rigidly connected to each other by a hollow carrier through which the engine shaft extends. The carrier has interior wall portions with a series of staggered projections thereon. The shaft has a stack... | 10/11/1983 |
| 4125350 | Mechanical die adjustment mechanism Apparatus for adjusting the rotary position of any selected one of a plurality of rotatable die bolts to control the position of a die lip and the size of a die opening adjacent the die lip comprising a reciprocable drive member movable in a to-and-fro pa... | 11/14/1978 |
