Filed:

Feb 9, 1998

Appl. No.:

/020528

Inventors:

Paul D. Cavanagh - Byfield MA

International Classification:

B66D 100

US Classification:

254266

Abstract:

The present apparatus includes an improved weather resistant marine winch arranged to permit the control of lines on a ship and to minimize water intrusion into the winch. The winch comprises a base for attachment to surface of the ship, the winch including a vertically oriented drive shaft supported over the base. A cylindrically shaped drum is rotatively disposed about the drive shaft, the drum having an upper drum flange and a lower drum flange. The upper drum flange has an upper hub portion on which an annular peeler bar is arranged. The peeler bar has a central bore with a shoulder therearound. A ring cap is fit about an upper end of the drive shaft, with a downwardly extending flange mating radially about the shoulder of the peeler bar. An annular "U" shaped groove is arranged about the outer periphery of the shoulder to divert any weather elements from infiltrating under the ring cap, thereby protecting the winch from the weather. Other annular seals are disposed between the lower flange and the base of the winch, and between the peeler bar and the central hub of the upper drum flange, as further water diversions between other rotating and stationary surfaces, to prevent infiltration of water into the inner workings of the winch.

International Classification:

B66D 100

US Classification:

254374

Abstract:

The present invention comprises an improved marine winch drum having a plurality of grooves of a specific geometry formed in the spool of the drum to increase the holding power of the drum with respect to the line received thereon and to minimize damage to the line wrapped around the drum.

Inventors:

John F. Cavanagh - North Providence RI

Assignee:

Cavanagh & Sons - Smithfield RI

International Classification:

A21D 1300

US Classification:

426497

Abstract:

Wafers are produced by guiding a sheet of bread having friable outer crusts and a relatively soft center through wafer forming apparatus. The apparatus includes a pair of rolls, one of said rolls, i. e. , a cutting roll having one or more wafer forming recesses or cavities therein and the other roll being a pressure roll which operates in rolling engagement with the cutting roll. As the sheet of bread is introduced into the nip formed between the two rolls the pressure roll acts to press the bread into the cavity or cavities on the cutting roll and into engagement with the edges of the cavity or cavities to cut wafers from the sheet of bread. Each cavity is configured to have a bottom surface which rises as a gradually tapering wall to a cutting edge which is coterminous with the surface of the cutting roll. Continuous production of wafers is possible with the edges of the wafers being sharply defined, free of undesirable crumbling and devoid of fracture lines.

Paul D. Cavanagh - Byfield MA

International Classification:

F16H 3700
B63H 1900

US Classification:

74 1569

Abstract:

The present invention comprises a transmission for the distribution of power from a rotating shaft, which shaft is supported between a pair of housing segments, which housing segments are connectedly joined to one another, including a rotatable shaft having a power source at one end thereof, for rotation of the shaft; a first housing enclosing at least a portion of the rotatable shaft, the housing having a first end with a plurality of spaced apart longitudinally directed holes therein; a flange having at least one radially directed projection thereon, the projection having a cammed surface which sweeps across the holes on the first end of the first housing; a second housing having a first end with a plurality of circumferentially spaced apart longitudinally directed holes therein; a plurality of reciprocally moveable pins disposed within the holes in the first and the second housing; and a cam arranged within the second housing, so as to effectuate longitudinal movement of the pins within the second housing to return their engagement with the holes in the first housing, thus locking the housing portions into non-rotative engagement with one another as the radially projecting cam sweeps past each pin.

International Classification:

F16H 408
F16D 2104
F16D 4302

US Classification:

74363

Abstract:

The present invention includes a passive shifting apparatus for a marine winch having a plurality of gears thereon. The passive shifting apparatus permits the winch to be rotated in either a clockwise or counter-clockwise direction, and comprises a central shaft about which the gears rotate, supported on a base in a marine winch housing. A rotatable curvilinear cam is mounted on the shaft. A radially inwardly and outwardly movable cam follower is engaged against the curvilinear cam. A first spring is arranged between the housing and the cam follower to bias the cam follower against the curvilinear cam. A second spring is arranged between the housing and the cam follower to bias the cam follower on the inner end of the shift arm when the cam is counter rotated. The cam follower may then move into and out of a slot in the curvilinear cam, and the cam may be able to rotate either clockwise or counter-clockwise without locking-up the cam follower.
