Total Claims: 4
Claim 1
Independent Claim
236 words
A trailer for carrying a boat or the like comprising: a frame having a forward end adapted to be detachably connected to a prime mover; transversely spaced wheels mounted to the rear of said frame; a plurality of rollers mounted in longitudinally spaced relation along the longitudinal axis of said frame for movably supporting a boat upon said frame; elongated stationary members placed on either side of the longitudinal axis for also supporting a boat in conjunction with said rollers; winch means mounted at the forward end of said frame for releasable engagement with a boat, said winch means capable of pulling a boat from the rear of said frame toward said forward end; and means mounted at the rear of said frame and operable to move the boat from a position resting upon said stationary members to a position raised above said stationary members, said boat raising means comprising an elongated lift roller mounted transversely to ane on the longitudinal axis of said frame, said roller mounted offset relative to its longitudinal axis; and further wherein a stop light is mounted to one side of said frame at the rear thereof, and wherein a handle is pivotally connected to said lift roller for movement in a plane perpendicular to the longitudinal axis of aid lift roller, said handle extendable over said stop light whereby said stop light limits movement of said handle in one direction.

Claim 3
Dependent Claim
31 words
A trailer as described in claim 1, and further wherein stop means is secured to said frame for limiting movement of said pivotal connection in a direction opposite said one direction.
Claim 4
Dependent Claim
91 words
A trailer as described in claim 2, and further wherein in the raised position of said lift roller, said handle is extendable forwardly of its pivotal connection relative to said trailer, with said stop light disposed below said handle to prevent rotation of said handle and said lift roller in one direction, and with said stop means disposed intermediate said stop light and said pivotal connection to limit rotation of said handle and said lift roller in an opposite direction, whereby said lift roller is substantially locked in a raised position.
