Abstract
A marine railway has a carriage pivotally connected to a support frame near the front of the carriage, and on a transverse horizontal axis. The rear of the support frame is carried by compression springs resting on the carriage. The support frame is provided with support abutments that are adjustable to accommodate the contour of the boat. A cable loop extends from a submerged pulley at the outer end of the railway, and engages a winch activated by a remote control unit. The carriage is interposed in one side of the loop.
Claims5
A marine railway carriage, comprising:
- a lower frame having substantially parallel spaced sides and provided with railway wheels;
- an upper frame pivotally connected to said lower frame at spaced points adjacent said sides, respectively, on a transverse horizontal axis adjacent the normally forward end of said lower frame;
- spring means connected at the opposite ends thereof to said lower and upper frame, respectively, adjacent the normally rear end of said lower frame, and biasing said frames toward separation;
- and
- support means on said upper frame adapted to engage a boat.
A marine railway, comprising:
- rail means intersecting the edge of a body of water;
- carriage means engaging said rail means;
- motive means including at least one pulley mounted below the level of said body of water at a position fixed with respect to said rail means, and also including a continuous cable loop engaging said pulley, and winch means adapted to drive said cable loop in opposite directions to induce movement of said carriage along said rail means, said loop having opposite sections, said carriage being interposed in one of said sections;
- and
- remote control means operative to control said winch means.
A marine carriage system, comprising:
- a carriage having supporting wheels;
- a continuous cable loop connected to said carriage;
- pulley means mounted below the level of a body of water outward from the shoreline thereof and engaging said cable loop;
- winch means including a capstan engaging said cable loop and adapted to induce motion in said cable loop in opposite directions transverse to said shoreline;
- cable-tension means engaging a section of said loop and interposed between said pulley means and said capstan;
- and
- remote control means operative to control said winch means.
A marine railway carriage, comprising:
- a lower frame provided with wheels;
- an upper frame pivotally connected to said lower frame on a transverse horizontal axis adjacent the normally forward end of said lower frame;
- spring means connected at the opposite ends thereof to said lower and upper frame, respectively, adjacent the normally rear end of said lower frame, and biasing said frames toward separation;
- a winch and cable system connected to said carriage, and a remote control for said system, said cable system including a cable loop having opposite sections, said carriage being interposed in one of said sections, and further including cable-tension means engaging said loop and interposed between said pulley means and said winch means;
- and
- support means on said upper frame adapted to engage a boat.
A marine railway carriage, comprising:
- a lower frame provided with wheels;
- an upper frame pivotally connected to said lower frame on a transverse horizontal axis adjacent the normally forward end of said lower frame;
- spring means connected at the opposite ends thereof to said lower and upper frame, respectively, adjacent the normally rear end of said lower frame, and biasing said frames toward separation;
- a cable terminal secured to said carriage and extending downward therefrom at an eccentric position on said lower frame;
- and
- support means on said upper frame adapted to engage a boat.
