Improvements in Rowlocks for Boats.
I EDWARD CHARLES MARTIN of 5 Pottery Street, Ipswich, in the County of
Suffolk, Manager of Works, do hereby declare the nature of this invention to be as
follows:-
My invention relates to an improved construction of rowlock for boats, and it
consists in mounting the rowlock on a plate adapted to be either fixed in position
for use or fixed under the gunwale when not in use, and in facing the moving parts
with vulcanite fibre or similar material, the objects being rigidity in
convenience in stowage.
use, and
In carrying my invention into practice I swivel the rowlock on a plate adapted
to fit on a plate fixed to the gunwale of the boat, and connected thereto by a pin
terminated in a ball. This pin fits in a hole formed in a projecting lug on the plate
fixed to the gunwale and so locates the position of the plate carrying the rowlock
thereon. The face of this lug is slotted through to the hole so that the pin which
is recessed may form a kind of ball connection between the two plates. On to the
plate carrying the rowlock a link is fulcrated and adapted to engage with projec-
tions on each end of the lug on the plate fixed to the gunwale of the boat
and so locks the plate carrying the rowlock in position both for use or for stowage.
The under side of the base of the rowlock and the underside of the plate carrying
the rowlock are both faced with vulcanite fibre attached by screws so as to be easily.
renewable. The hole to receive the swivel pin of the rowlock is also lined with
vulcanite fibre for the same purpose.

COMPLETE SPECIFICATION.
Improvements in Rowlocks for Boats.
I EDWARD CHARLES MARTIN of 5 Pottery Street, Ipswich, in the County of
Suffolk, Manager of Works, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
My invention relates to an improved construction of rowlock for boats, and it
consists in mounting the rowlock on a plate adapted to be either fixed in position
for use, or fixed under the gunwale when not in use, and in facing the moving parts
with vulcanite fibre, or similar material, the objects being rigidity and durability in
use, and to obviate the noise caused by the metallic parts when in direct contact.
In carrying my invention into practice I swivel the rowlock on a plate adapted
to fit on a plate fixed to the gunwale of the boat and connected thereto by a pio
terminated in a half ball. This pin fits in a hole formed in a lug on the
plate fixed to the gunwale and so locates the position of the plate carrying the
rowlock thereon. The face of this lug is slotted through to the hole, so that
the pin which is recessed may form a kind of working or movable connection
between the two plates, the traverse of this pin being determined by two small
studs fixed one at each end of the slotted hole in the plate fixed to the gunwale.
To enable the connection between the two plates to be broken when desired, the

page_text: end of the pin is recessed to admit of its passing over the said studs. On to the
plate carrying the rowlock a link is fulcrated and adapted to engage with
projections on each side of the lug on the plate fixed to the gunwale of the
boat, and so locks the plate carrying the rowlock in position both for use or for
stowage.
"
The underside of the base of the rowlock is faced with vulcanite fibre attached
by screws so as to be easily renewable. The hole to receive the swivel pin of the
rowlock is also lined with a non-metallic substance for the same purpose.
In order that my invention may be fully understood I will more particularly
describe it making reference to the accompanying drawing in which
Figure 1 is a view in side elevation-looking from the interior of the boat-
showing the rowlock in position, and
+
Figure 2 is a similar view showing the rowlock folded within the boat.
Figure 3 is view in transverse section through line a.. Figure 1, and
Figure 4 is a view in side elevation of the rowlock folded as shown by Figure 2.
Throughout these views similar parts are marked with like letters of reference.
The rowlock A is mounted on a plate B so as to be free to swivel thereon in the
ordinary manner. This plate B is adapted to fit on to a plate fixed to the
gunwale X of the boat.
**On the plate B is formed or fixed a depending pin B' terminating in a half
ball as shown. On the front of the plate C is formed a socket in the face
of which is cut a slot c of a width slightly greater than the diameter of the
pin B The half ball on the end of the pin B forms a working or movable
connection between the two plates B and C, and allows the plate B carrying
the rowlock to be placed in either of the positions shown by Figures 1 and 2
of the accompanying drawing. To lock the plate B in both these positions a
link D is fulcrated on the plate B, and is adapted to engage with projections c
on each end of the socket C'as shown by the drawing. To retain the half ball 6 in
the socket C small studs ce are fixed near each end thereof, and to enable the two
plates B and C to be disconnected when desired a recess is formed in the free
end of the half ball to allow the said half ball' to' pass over either of the studs.
The underside of the plate B carrying the rowlock A is faced with vulcanite
fibre or other suitable non-metallic material E to prevent the metallic contact of
the two plates. This facing is preferably fixed to the plate by screws so that it
can be readily renewed when worn. The pin A by which the rowlock is allowed
to swivel on the plate B is also faced with vulcanite fibre or other suitable non-
metallic material E' for the same purpose.
I wish it to be particularly understood that I do not limit myself to the precise
details of construction hereinbefore described and shown but that I hold myself
at liberty to make such changes and alterations as fairly fall within the spirit and
scope of my invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
"The improved method of mounting a boat rowlock, substantially as and for
the purpose hereinbefore described and shown.
2. in.a boat rowlock, facing the wearing parts with a non-metallic material, as
and for the purpose set forth..
3. In a boat rowlock, mounting the plate carrying the rowlock on a plate fixed
to the gunwale of the boat by means of a depending pin on the rowlock plate
engaging with a socket on the plate on the gunwale of the boat, and by means
of a link fulerated on the rowlock plate and adapted to engage with one or
other of two series of projections on the socket on the plate on the gunwale of the
boat, as set forth.
4. The combination of the rowlock A, of the plate Bon which the rowlock is
mounted so as to be free to swivel thereon, of the pin B having a half ball 6 on its

page_text: free end, of the plate C adapted to be fixed to the gunwale of the boat and
carrying a socket C¹ slotted down its front, of the link D fulcrated on the plate B,
and of the projections c', c', on the ends of the socket C', all combined arranged
and operating as and for the purpose set forth.
5. The combination of the rowlock A, of the plate B on which the rowlock is
mounted so as to be free to swivel thereon, of the pin B₁ having a half ball on its
free end, of the plate C adapted to be fixed to the gunwale of the boat and carrying
a socket C¹ slotted down its front, of the link D fulcrated on the plate B, of the
projections cc on the socket C, of the studs c c², in the socket C', and of the
recess in the end of the half ball on the pin B1, all combined arranged and
operating as and for the purpose set forth.
