Abstract: Hydraulic pump applications sometimes require the pump to be able to provide relatively low pressure with larger amounts of fluid moved, while other applications call for relatively higher pressures but less fluid moved. The multi-speed hydraulic pump can operate at multiple speeds so as to provide multiple outputs of pressure and flow. In a two-mode version, the pump has one mode of operation that provides for lower pressure/more fluid moved and another mode of operation that provides for higher pressure/less fluid moved. Having multiple modes of operation in the pump allows for a single pump to provide greater movement or greater pressure while working within the limits of the force or speed at which the pump is actuated.

Abstract: A pedestal (1) for a sailing boat comprises a casing (2) and inside such a casing (2): at least one driving wheel (11a, 11b) associated with a motion input shaft (3), at least one driven wheel (12a, 12b) associated with a motion output shaft (4) and at least one motion transmission element (13a, 13b) from said at least one driving wheel (11a, 11b) to said at least one driven wheel (12a, 12b). The pedestal (1) further comprises, also inside the casing (2), a speed variation system selectively activatable to vary the rotation speed of the motion output shaft (4) with respect to that of the motion input shaft (3).

Abstract: The features of a known auto shifting three speed winch having a drive shaft and rotatable drum are used to provide first, third and fourth gears upon reversal of rotation of the drive shaft. The third and fourth gears use common gearing and the final gear meshed with the drum. A separate drive train is provided for second gear and includes planetary gears having carriers secured to the drum and operating between a sun gear on the shaft and an outer ring gear. Second gear is selected by means of pawls brought into engagement with a ratchet track on the ring gear, with the pawls being connected to torsion springs controlled manually by a lever arrangement. When second gear is engaged, the winch can shift between only second and third, with fourth being overridden.

Abstract: A backwind feature is provided on a line-receiving winch and is particularly suitable for use on high capacity sailboat winches. The winch includes a main drive train to drive the drum of the winch in a winding direction and to prevent rotation in the opposite direction. A planetary gear assembly is provided on the output shaft of the winch, which permits independent rotation of the drum by a separate worm drive, without the need to disconnect any portion of the main drive.

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.

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.

Abstract: Multi-pedestal winch system with disconnect automatic reconnect.

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.

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.

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.
