Abstract
Abstract A stay release for anchoring and tensioning a stay wire on a sailboat is comprised of a generally cylindrical housing which is secured to the deck of the boat. A rotary lever is arranged to engage a fitting at the end of the stay wire when the fitting is inserted through an opening in the housing. The rotary member can be turned by a winch handle or the like through an angle of about 180*, thereby pulling the stay wire down toward the deck and tensioning it. A spring loaded pin mounted in the housing engages the rotary member and locks it in a position at which the stay wire passes just beyond the axis of the rotary member so that the stay wire does not tend to rotate the lever in the opposite direction, yet imparts relatively little torque to that member.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
174 words
A stay release for anchoring and tensioning a stay wire on a boat comprising A. a housing whose inside volume is generally cylindrical in shape, B. a generally cylindrical drum whose diameter is slightly less than the diameter of the inside volume of the housing, said drum being mounted inside the housing for rotation about its axis, C. an abutment on the drum, D. a channel extending from the abutment diametrically through the drum, E. a circumferential slot in the top wall of the housing, said slot being aligned with the channel in the drum so that an elongated rigid fixture can be inserted through the housing to engage the abutment, and the drum can be rotated about its axis so that the abutment is moved from an upper position to a lower position within the housing with the fixture extending through the channel and projecting out of the slot, F. means for rotating the drum around its axis between its two positions, and G. means for stopping the drum in its lower position.
Claim 2
Dependent Claim
174 words
A stay release for anchoring and tensioning a stay wire on a boat comprising A. a housing whose inside volume is generally cylindrical in shape, B. a generally cylindrical drum whose diameter is slightly less than the diameter of the inside volume of the housing, said drum being mounted inside the housing for rotation about its axis, C. an abutment on the drum, D. a channel extending from the abutment diametrically through the drum, E. a circumferential slot in the top wall of the housing, said slot being aligned with the channel in the drum so that an elongated rigid fixture can be inserted through the housing to engage the abutment, and the drum can be rotated about its axis so that the abutment is moved from an upper position to a lower position within the housing with the fixture extending through the channel and projecting out of the slot, F. means for rotating the drum around its axis between its two positions, and G. means for stopping the drum in its lower position.
Claim 3
Dependent Claim
19 words
The stay release defined in claim 1 and further including means for locking the drum in its lower position.
Claim 4
Dependent Claim
55 words
when the drum is rotated to its lower position, the stay wire is pulled downward and moved just to the other side of the rotary axis of the drum so that the tensioned stay wire does not tend to rotate the drum in the opposite untensioning direction, yet exerts relatively little torque on the drum.
Claim 5
Dependent Claim
55 words
when the drum is rotated to its lower position, the stay wire is pulled downward and moved just to the other side of the rotary axis of the drum so that the tensioned stay wire does not tend to rotate the drum in the opposite untensioning direction, yet exerts relatively little torque on the drum.
Claim 6
Dependent Claim
42 words
A stay release system comprising A. a stay wire having one end anchored to a mast and its other end terminating in a fitting, B. a stay release as defined in claim 1 anchored well below said one end, and C. wherein
