Filed:

Sep 5, 1989

Appl. No.:

7/403997

Inventors:

William C. Ottemann - Fremont CA
Richard A. Gabellini - Aptos CA

Assignee:

IMI-Barient, Inc. - Guilford CT

International Classification:

B66D 108

US Classification:

254284

Abstract:

A power sailboat winch mechanism for the high speed gathering of running rigging line under initial low tension with final slow speed gathering of the same line under final high tension combined with line storage is disclosed. The winch mechanism includes two drums handling the line in series, these drums constituting a winding drum and a high torque drum. The winding drum is provided threaded to the bitter end of the line with a level wind for even distribution of the line along the drum. This winding drum provides initial rapid line take-up, tailing force to a high torque winch drum and line storage for the requisite amount of line used in the particular running rigging handled by the winch. A conventional high torque winch drum is provided between the winding drum and line load. This high torque winch is provided with surfaces to induce line climbing of the drum by conventional crowd climbing over the drum surface.

William C. Ottemann - Menlo Park CA

Barient, Inc. - Santa Ana CA

International Classification:

B66D 120
B66D 122
F16H 572

US Classification:

254344

Abstract:

A three speed winch has two alternative inputs. The first input shifts the winch between first, second and third gear trains by successive reversals of the direction of an input member. The alternative input drives the winch at two different speeds responsive to rotation of an input member in opposite directions. The alternative input may be connected to drive the winch in either first or third gear so that the winch provides seven gear ratios. There are four pairs of gear ratios available by simple reversal of direction of an input, and the winch has three different ratios between the gear ratios of the different pairs.

Assignee:

International Marine Industries - Guilford CT

International Classification:

B63H 910

US Classification:

114107

Abstract:

In a sailboat having a sail such as a Genoa jib with roller reefing for spirally winding the sail on a fairing around a stay, a winch mechanism for turning the fairing about the stay and spirally winding the sail to and from the fairing is disclosed. The winch includes a high mechanical advantage clutch, preferably a cone clutch, normally engaged by load between the sail and sheet exerting an unwinding force upon the fairing through the normally engaged clutch to a normally stationary clutch driving shaft. The clutch driving shaft has a first clutch member ratchetted from the vessel to permit turning of the entire clutch for taking in of the sail. The clutch includes a second clutch member attached for rotation with the fairing relative to the vessel and driven for both sail take-up and let out by the normally stationary clutch driving shaft. The normally stationary clutch driving shaft is in turn driven usually by a hydraulic motor or upon motor failure by a ratchetted winch handle.

Appl. No.:

5/962246

Inventors:

William C. Ottemann - San Carlos CA

Assignee:

Barient Company - San Carlos CA

International Classification:

B66D 130

US Classification:

254333

Abstract:

A deck winch for sailing craft provides a direct drive from main shaft to drum and has a self-tailing capability. Pawls mounted in the drum near its upper end extend through an arcuate opening in a stationary extended base member to engage the shaft intermittently. The base member affords a fixed mount at its upper end for the line lifter of a self-tailing device and comprises a cylindrical sleeve whose axis is offset from the axis of the main winch shaft. As a crank turns the shaft, each pawl progressively projects through the base member opening to drivingly engage the shaft for a portion of a revolution and then is cammed outwardly out of engagement as the next pawl takes over. The invention provides a relatively simple winch having both direct drive and self-tailing capabilities.

Appl. No.:

6/586113

Inventors:

Christopher E. Boome - Woodside CA
William C. Ottemann - San Carlos CA

Assignee:

Barient, Inc. - Menlo Park CA

International Classification:

B66D 100

US Classification:

254266

Abstract:

A pedestal winch with variable radius crank arms. The winch is intended for use on a sail boat or the like. The crank arms each include two telescoping sections together with a locking apparatus for locking the sections together in differing positions so as to achieve differing radii. A thumb-actuated operating member is positioned adjacent each crank handle for controlling the locking apparatus. Accordingly, an operator need not remove his/her hands from the crank handles in order to switch the winch between a short radius position for high speed winching and a long radius position for high power winching.
