Abstract

Abstract Water ski towline reel apparatus is disclosed which may be detachably affixed to a semi-permanently fixed bracket disposed at the rear of a towboat. An elongated rod is provided with two right angle bends directed such that the rod ends are parallel to one another. An outer rod end is adapted to receive the reel acting as the shaft therefor. The inner rod end is welded to a channel member after being inserted through aligned holes in opposite sides and near one end thereof. The channel member is provided with a pair of notches near its other end and is adapted to pass vertically through a pair of apertures in a U-shaped mounting bracket affixed to the rear of a towboat. The length of the channel member is sufficient for the end carrying the reel shaft to clear the upper surface of the upper bracket leg when the notches engage the lower bracket leg. Spring loading means bearing on the side of the channel member urge the notches into such engagement until it is desired to remove the reel apparatus from the bracket. When such removal is to be effected, the channel member is pushed against the spring means to disengage the notches from the lower bracket arm such that the channel member and reel assembly may be lifted through the apertures in the channel arms for remote storage. A three position friction brake variably bears against one side of the reel to achieve locking, restraining, and free-running operation as may be required during use of the apparatus. The rope is fed through the channel member beneath the inner rod end in order to provide a safety factor in which a knot in the rope near the attached end is stopped, because of its size, between the rod end and the upper surface of the upper bracket leg. Thus, any sudden strain resulting from complete pay-out of the towline from the reel is taken by the bracket rather than the reel.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 177 words
Watercraft towline pay-out and retrieval apparatus comprising: A. a bracket having a first leg, a second leg, and a connecting portion between said first and second legs; B. means for fixing said bracket to a watercraft; C. an elongated channel member, said channel member being provided with a pair of aligned notches on spaced apart sides thereof and proximate a first end thereof; D. a reel assembly; E. shaft means rotatably supporting said reel assembly, said shaft means being rigidly fixed to said channel member proximate a second end thereof; F. a first rectangular aperture in said first leg of said bracket, said first rectangular aperture being dimensioned and configured to receive said channel member with sliding clearance; G. a second rectangular aperture in said second leg of said bracket, said second rectangular aperture being dimensioned and configured to receive said channel member with sliding clearance; and H. spring means supported on said bracket and adapted to urge said notches proximate said second end of said channel into engagement with an edge of said second rectangular aperture.
Claim 2
Dependent Claim 177 words
Watercraft towline pay-out and retrieval apparatus comprising: A. a bracket having a first leg, a second leg, and a connecting portion between said first and second legs; B. means for fixing said bracket to a watercraft; C. an elongated channel member, said channel member being provided with a pair of aligned notches on spaced apart sides thereof and proximate a first end thereof; D. a reel assembly; E. shaft means rotatably supporting said reel assembly, said shaft means being rigidly fixed to said channel member proximate a second end thereof; F. a first rectangular aperture in said first leg of said bracket, said first rectangular aperture being dimensioned and configured to receive said channel member with sliding clearance; G. a second rectangular aperture in said second leg of said bracket, said second rectangular aperture being dimensioned and configured to receive said channel member with sliding clearance; and H. spring means supported on said bracket and adapted to urge said notches proximate said second end of said channel into engagement with an edge of said second rectangular aperture.
Claim 3
Dependent Claim 46 words
The towline pay-out and retrieval apparatus of claim 1 in which said spring means is oriented on said bracket to urge said second end of said channel toward said bracket connecting portion whereby said notches engage an edge of second rectangular aperture nearest said connecting portion.
Claim 4
Dependent Claim 93 words
The towline pay-out and retrieval apparatus of clAim 2 in which: A. said shaft means comprises a rod having first and second right angle bends providing first and second rod end portions parallel to one another; B. said reel means being rotatably journalled on said first rod end portion; and C. said second rod end portion being rigidly fixed to said channel proximate said first end thereof, said second rod end portion being positioned outwardly from said first leg of said bracket when said notches engage an edge of said second rectangular aperture.
Claim 5
Dependent Claim 136 words
The towline pay-out and retrieval apparatus of claim 3 which further includes: A. a brake lever fixed at a pivot point to said shaft means proximate said first right angle bend, said brake lever having first, second, and third edges disposed, respectively, first, second, and third distances from said pivot point; B. said reel assembly having first and second sides and a hub extending therebetween; and C. a spring washer disposed on said upper rod end portion between said first side of said reel assembly and said pivot point whereby rotation of said brake lever about said pivot point selectively brings said first, second, and third edges thereof to bear against said spring washer such that said spring washer is variably urged against said first side to provide first, second, and third degrees of reel braking.
