Abstract
Abstract A boat and trailer combination in which a hoisting attachment is provided for pivoting the boat either end-over-end or sideways about detachable hinges, by which the boat is connected to the trailer, from an inverted position on the trailer to an upright position beside the trailer. The hoisting attachment includes a mast which provides an elevated position from which to lift the boat about the hinges and a winch which is desirably designed so that the cable can be paid out only by reversing the operating input to the winch, as by reversing the direction in which the handcrank is rotated. By locating the mast near the axis of the hinges, rotation of the crank on the winch in one direction raises the boat up to the mast, and then after the boat swings past the mast, the crank on the winch is reversed so that the boat is gently lowered from the mast to a position adjacent the trailer or onto the trailer, depending on whether the boat is being unloaded or loaded.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
241 words
A boat and trailer combination in which the boat is carried by the trailer in an inverted position with the boat detachably hinged to the trailer adjacent one of its longitudinal anD transverse extremities with the pivot axis about which the boat is hinged disposed adjacent a peripheral portion of the boat and parallel to one of its longitudinal and transverse axes, such that the boat can be swung through substantially 180* between its inverted position on the trailer and an unloaded position adjacent the trailer, hoisting means for swinging the boat about said pivot axis for loading the boat onto and unloading it from said trailer, said hoisting means comprising in combination, a mast mountable near said pivot axis and clear of the boat in the direction of said pivot axis, a winch having a hoisting line supported by said mast for swinging the boat about said pivot axis, fastening means for attaching said hoisting line to said boat at a predetermined distance from said pivot axis, and guide means on said mast over which said hoisting line is trained as it passes from said winch to said fastening means on the boat, said guide means being located on said mast a predetermined distance above said pivot axis, the distances of said fastening means and said guide means from said pivot axis being selected such that adequate leverage is provided for lifting and lowering the boat about said pivot axis.
Claim 2
Dependent Claim
241 words
A boat and trailer combination in which the boat is carried by the trailer in an inverted position with the boat detachably hinged to the trailer adjacent one of its longitudinal anD transverse extremities with the pivot axis about which the boat is hinged disposed adjacent a peripheral portion of the boat and parallel to one of its longitudinal and transverse axes, such that the boat can be swung through substantially 180* between its inverted position on the trailer and an unloaded position adjacent the trailer, hoisting means for swinging the boat about said pivot axis for loading the boat onto and unloading it from said trailer, said hoisting means comprising in combination, a mast mountable near said pivot axis and clear of the boat in the direction of said pivot axis, a winch having a hoisting line supported by said mast for swinging the boat about said pivot axis, fastening means for attaching said hoisting line to said boat at a predetermined distance from said pivot axis, and guide means on said mast over which said hoisting line is trained as it passes from said winch to said fastening means on the boat, said guide means being located on said mast a predetermined distance above said pivot axis, the distances of said fastening means and said guide means from said pivot axis being selected such that adequate leverage is provided for lifting and lowering the boat about said pivot axis.
Claim 3
Dependent Claim
53 words
The combination defined in claim 1, wherein said fastening means and said guide means are spaced at substantially equal distances from said pivot axis so that as the boat is pivoted from a horizontal position to a vertical position, said fastening means on the boat passes near said guide means on said mast.
Claim 4
Dependent Claim
36 words
The combination defined in claim 1, wherein the boat is hinged at its stern to the rear of the trailer, said mast being mountable at the rear of the trailer to one side of the boat.
Claim 5
Dependent Claim
59 words
The combination defined in claim 3, wherein said mast comprises an upright member pivotally mounted on said trailer so that it can be swung from its operative position to a storage position in which it is disposed substantially parallel with the body of the trailer, said mast also including means for bracing said upright member in its operative position.
Claim 6
Dependent Claim
39 words
The combination defined in claim 3, wherein said mast comprises an upright member mountable on said trailer in a substantially vertical position, said winch being mounted on said upright member at a convenient height for manipulation by the operator.
Claim 7
Dependent Claim
63 words
The combination defined in claim 1, wherein said boat is hinged at one side to the side of the trailer, said mast being mountable adjacent said one side of the boat and clear of the boat in the direction of said pivot axis so that it does not interfere with the boat as the boat is swung sideways while being loaded and unloaded.
Claim 8
Dependent Claim
28 words
The combination defined in claim 6, wherein said boat is carried bow first on said trailer and said mast is mounted rearward of the stern of the boat.
Claim 9
Dependent Claim
18 words
The combination defined in claim 3, wherein said winch is reversible only upon reversing the power input thereto.
Claim 10
Dependent Claim
137 words
The combination defined in claim 4, wherein said bracing means comprises an elongated strut having an upper section pivoted at one end to said upright member at a point spaced from its pivotal mounting on the trailer, said strut having a lower section pivoted at one end to said trailer at a point spaced from said upright member, pivot means connecting said upper and lower strut sections to each other adjacent their other ends and overlapping each other when aligned, said upright member being in its operative position when said strut sections are aligned, and means for releasably fastening said strut sections at a second point in their overlapping portions spaced from said pivot means in order to lock said strut sections in alignment with each other and to fix said upright member in its operative position.
Claim 11
Dependent Claim
139 words
The combination defined in claim 9, wherein the distance from the point at which said upright member is pivoted to the trailer to the point at which said upper strut section is pivoted to said upright member plus tHe distance from the pivot point of said upper strut section with said upright member to said pivot means is substantially equal to the distance from said pivot point of said upright member with the trailer to the pivot point of said lower brace member with the trailer plus the distance from said pivot point of said lower brace with the trailer to said pivot means, such that said upright member may be swung down so that it and said strut sections lie substantially parallel or flush with the body of the trailer while maintaining said pivotal connections with each other.
Claim 12
Dependent Claim
98 words
The combination defined in claim 10, wherein said upright and strut sections comprise U-shaped channels, the inside dimensions of the channel of said upright member and lower strut section being substantially the same and large enough to receive the outside dimensions of said upper strut section, the open side of the channels of said upright member and said lower strut section facing each other such that said upper strut section is pivotally connected within the side flanges of said upright member and lower strut section and is completely nested therein when in the stored position of said mast.
