IMPROVEMENTS IN ROWLOCKS
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
We EDWARD JOHN PITTOCK BROWN, of N° 112 Snargate Street, Dover, in the
County of Kent, Engineer, and GEORGE WILLIAM WELLER PAINE, of Kebir Villa,
Folkestone Road, Dover, in the County of Kent, Master Mariner, do hereby declare
the naturo of our invention for IMPROVEMENTS IN ROWLOCKS to be as follows:-
Our invention relates to improvements in Rowlocks for boats of all kinds, and it
has for object, to permit the rowlock to be removed from its vertical position upon
the gunwale while keeping it secured to the boat in a convenient position, and in
such a manner that it cannot be abstracted excepting by using considerable force,
or by the use of an instrument.
The upper part of our improved Rowlock will be of any of the ordinary forms
having a stem passing through the gunwale, but we propose to divide this stea
horizontally and to again unite the parts by a link or joint hinged both to the
upper and lower part, the length of this link somewhat exceeding the distance
from the hole through which the stem of the rowlock is passed to the inner edge of
the gunwale.
The stem will be pierced near the lower end by a hole into which we place a pin
split so that it cannot be readily driven out, and which prevents the withdrawal of
the stem of the rowlock by the hole through which it has been inserted.
The result of this construction is, that when the Rowlock is not required for use
it is only necessary to pull it up until the pin meets the underside of the gunwale
and then to turn it over inwards, when the link or joint will lie horizontally upon
the gunwale and the rowlock fall head downward and lie against the inside of the
boat.
When required for use, it will only be necessary to throw the rowlock upward,
and the stem, descending through the hole in the gunwale, will draw the link or
joint with it until the Rowlock is in its proper position.
Our device leaves the rowlock free to turn in the hole in the usual way,

Folkestone Road, Dover in the County of Kent, Master Mariner, do hereby declare
the nature of our invention for IMPROVEMENTS IN ROWLOCKS" and in what inanner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
Our Invention relates to improvements in Rowlocks for Boats of all kinds, and
it has for object to permit the Rowlock to be removed from its vertical position
upon the gunwale, while keeping it secured to the boat in a convenient position
and in such a manner that it cannot be abstracted excepting by using considerable
force, or by the use of an instrument.
Upon the accompanying Sheet of Drawing.
Figure 1, Represents a Rowlock einbodying our Invention, as seen from the
interior of a boat when shipped for use.
Figure 2 being an end view of same.
Figure 3°. Is a plan view from which it will be seen that the Rowlock is free to
revolve as shown in dotted lines, and
Figure 4°. represents a section through the gunwale the Rowlock being shown
unshipped.
A indicates tho Rowlock.
B the upper portion of stem of same.
C the gunwale of the boat.
D hole in gunwale through which the stem B passes.
E groove formed in upper surface of cleat on gunwale for link F of the stem to
lie in when the rowlock is unshipped.
F link connecting upper and lower portion of stem.
G lower portion of stem.
H split pin or cottar for securing stem in gunwale.
The upper part A of our improved rowlock may be of any of the ordinary
forms having a stem B passing through the gunwale C, but it will be seen that we
divide this stem horizontally and again unite the parts by the link or joint F
hinged both to the upper part B and to the lower part G of the stem, the length
of this link somewhat exceeding the distance from the hole D, through which the
stem B of the rowlock is passed, to the inner edge of the gunwale.
The stem is pierced near the lower end G by a hole into which is placed a pin H,
split so that it cannot be readily driven out, and which prevents the withdrawal of
the stem of the rowlock by the hole D through which it has been inserted.
We may substitute for this split pin H any kind of stop piece, fixed or
movable.
The result of this construction is, that when the Rowlock is not required for use,
it is only necessary to pull it up until the pin, or stop H meets the under side of
the gunwale C, and then to turn it over inwards; the link or joint F then falls
into and lies horizontally in the groove E upon the gunwale, and the rowlock A
falls head downward and lies against the inside of the boat, as shown in Fig 4.
When required for use, it is only necessary to throw the Rowlock A upward,
and the stem B, descending through the hole D in the gunwale draws the link
or joint F with it until the rowlock is in its proper position for service, sec
Figs 1, 2 and 3.

page_text: Our devico leaves the Rowlock free to turn in the hole D in the usual way—as
illustrated Figure 3.
Our improved Rowlock may be made of wrought iron galvanized, or of any
suitable metal or material, and of any shape, and we do not limit ourselves to any
particular form of link or joint F, to any mode of attaching this part F to tho
parts B and G (so that a suitable joint be obtained) or to the use of the split
pin H, as these details may be modified while retaining our invention.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
We Claim is :-
1°. A Rowlock constructed, combined and arranged to be operated substantially
as herein before described and shown on the accompanying Drawings.
2°. In a Rowlock the link or joint F, substantially as described for the purpose
specified.
