IMPROVEMENTS IN CAPSTANS, WINDLASSES, CHAIN AND WIRE CABLE HOLDERS AND RIDING BITTS
Year: 1882

page_text: LETTERS PATENT to Samuel Baxter of 18 and 19 Great St. Helen's in
the City of London for an Invention of IMPROVEMENTS IN CAPSTANS,
WINDLASSES, CHAIN AND WIRE CABLE HOLDERS AND RIDING BITTS
PROVISIONAL SPECIFICATION left by the said Samuel Baxter at the Office
of the Commissioners of Patents on the 19th June 1882.
SAMUEL BAXTER of 18 and 19 Great St. Helen's in the City of London
"IMPROVEMENTS IN CAPSTANS, WINDLASSES, CHAIN AND WIRE CABLE HOLDERS
AND RIDING BITTS"
The Invention has for its object improvements in Capstans, Windlasses, Chain
and Wire Cable Holders and Riding Bitts.
Heretofore the above mentioned articles have been made from wrought iron and
the parts thereof have been rivetted, screwed and bolted together thereby involving
considerable cost and time in their production.
According to my present invention I form the above mentioned articles in cast
steel and I anneal them in order to impart toughness thereto.
In carrying my Invention into effect I cast the entire or as much of the said
articles in one piece as can be conveniently cast in one operation and afterwards
annealed and manipulated and in the case of capstans windlasses and cable
holders I provide the castings with suitable bosses or enlargements which I bore
to fit the shafts or axes to which they are applied.
In the case of riding bitts I cast the cylinder, base and shelf in one piece and
I bore the holes to receive the stems or shanks of the projecting pieces on which
the cable rides and I form such projecting pieces and their stems or shanks
separately of cast steel which I afterwards anneal.
By these means I obtain great economy in the cost and time of production of
such articles together with greater solidity and reliability in use than when such
articles are built up in wrought iron as heretofore.

WIRE CABLE HOLDERS
This Invention has for its object improvements in capstans, windlasses chain and
wire cable holders and riding bitts.
Heretofore the above mentioned articles have been made from wrought iron
and the parts thereof have been rivetted screwed and bolted together thereby
involving considerable cost and time in their production.
According to my present invention I form the above mentioned articles in cast
steel and I anneal them in order to impart toughness thereto.
In carrying my invention into effect I cast the entire or as much of the said
articles in one piece as can be conveniently cast in one operation and afterwards
annealed and manipulated and in the case of capstans windlasses and cable
holders I provide the castings with suitable strengthening webs or pieces and
with bosses or enlargements where required which latter 1 bore to fit the shafts or
axes to which they are applied.
In the case of riding bits I cast the cylinder, base and shelf in one piece and
I either cast or bore the holes to receive the stems or shanks of the projecting
pieces on which the cable rides and I form such projecting pieces and their stems
or shanks separately of cast steel which I afterwards anneal.
In the case of windlasses I cast as much of the different parts as can be conveniently
cast in one operation bosses enlargements and strengthening pieces being cast where
required. In a Specification of a former Patent granted to me and dated the 11th day
of November 1880 (No. 4649) I have described a vertical windlass on a bed plate
with tubes to carry the cable holders and through which the driving spindles pass,
this hitherto has been made in cast iron. I now cast this bed plate, with the tubes,
the necessary steps for spindles and half bearings all complete in steel but in two
halves with flanges and lugs cast thereon for securing the two halves together and
also with flanges and lugs on the lower half for bolting the same to the deck, by
this means less space and less weight are required while much greater strength is
obtained than when the same is made in cast iron.
By these means I obtain great economy in the cost and time of production of
such articles together with greater solidity and reliability in use than when such
articles are built up in wrought iron as heretofore.
Having thus described the nature of my said Invention and the mode in which
carry the same into effect I would have it understood that what I claim is, the
manufacture of capstans, windlasses, chain and wire cable holders and riding bitts
by casting them in steel and annealing the same as herein described.

In witness whereof I the said Samuel Baxter have hereunto set my hand
and seal this eighteenth day of December in the year of our Lord One
thousand eight hundred and eighty two.
