Abstract
A winch for tightening lines and webbing on the lashing of cargos, the winch having a frame which consists of two preferably oval plates which are spaced from each other by means of cross-pieces, of which the one is used as an anchorage for the winch and the other for securing one end of the webbing, and a winding roller located between the cross-pieces and connectible to the other webbing end and having a ratchet mechanism in the form of two disks abutting against each other under the action of a spring, the disks having radial locking surfaces on their sides in abutment with each other and being movable apart for canceling the locking action by means of a clutch ring located between the disks.
Claims4
A winch for lines and webbing, comprising a frame consisting of two plates spaced from each other,
- cross-pieces between said plates, one of said cross-pieces forming means for anchoring said frame to a stationary object, and another of said cross-pieces forming means for anchoring one end of a line,
- a winding roller rotatably journalled in said frame having a line securing portion thereon,
- a housing on said frame fixedly mounted to one of said plates, and
- a ratchet mechanism for said winding roller disposed in said housing,
- said ratchet mechanism comprising two ratchet disks concentric with said winding roller and in abutment with each other, one of said disks being rigidly connected to said winding roller and the other being axially movably journalled in said housing against the action of a spring, ridges which are saw-toothed shaped in cross-section on the sides of said ratchet disks facing each other having radial locking surfaces thereon, a clutch ring rotatably journalled in said housing between said ratchet disks, said ring having clutch portions directed towards its center and there is provided wedge-shaped portions along the periphery of said axially movable disk, said clutch portions being shiftable into engagement with said wedge-shaped portions by the rotation of said clutch ring for shifting of said axially movable disk against the action of said spring such that the locking surfaces of said disks are disengaged from each other, and an operating arm connected to said clutch ring and projecting from said housing adjacent the outwardly facing side of said one plate.
