PROVISIONAL SPECIFICATION.
Improvements in Folding Row-lock Carrying Frames for Outrigged
Boats.
1, SAMUEL EDGAR SAUNDERS, of Goring-on-Thames, in the County of
Oxford, Boat Builder, do hereby declare the nature of this invention to be
as follows:-
My invention relates to row-lock carrying frames for outrigged boats and has
for its object to provide improved means for folding such frames.
According to my said invention the carrying frame consists essentially of two
arms which at their outer ends, at the point where the row-lock is carried, are
jointed together while the inner end of one arm is adapted to fit into a socket
attached to the gunwale of the boat the inner end of the other arm fitting into a
clip. The socket is adapted to partially rotate on a horizontal or nearly horizontal
axis, so that after the arm held by the clip has been disengaged therefrom the two
arms can be folded together and moved parallel to the gunwale and can then be
turned down so as to lie against the inside of the boat. The arm is retained
in the rotatable socket by an eccentric head or collar at its extremity or by any
other desirable means.
In some cases where long outrig frames are employed I find it advantageous
to use in connection with each frame a third arm. This third arm is jointed
to the outer ends of the arms herein before described and at its inner end
is supported against the side of the boat so as to form a strut or support for
the frame.

COMPLETE SPECIFICATION.
Improvements in Folding Row-lock Carrying Frames for Outrigged
Boats.
I, SAMUEL EDGAR SAUNDERS, of Goring-on-Thames, in the County of Oxford,
Boat Builder, do hereby declare the nature of this invention, and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
My invention relates to row-lock carrying frames for outrigged boats, and has
for its object to provide improved means for folding such frames.
According to my said invention the carrying frame consists essentially of two
arms which at their outer ends, at the point where the row-lock is carried, are
jointed together while the inner end of one arm is adapted to fit into a socket
attached to the gunwale of the boat, the inner end of the other arm fitting into a
clip. The socket is adapted to partially rotate on a horizontal or nearly horizontal
axis, so that, after the arm held by the clip has been disengaged therefroin, the two
arms can be folded together and moved parallel to the gunwale and can then be
turned down so as to lie against the inside of the boat. The arm is retained in the
rotatable socket by an eccentric head or collar at its extremity or by any other
desirable means.
:-
To enable my invention to be fully understood I will describe how it can
be carried into practice by reference to the accompanying drawings, in which :-
Figure 1 is a plan of a folding row-lock carrying frame for outrigged boat;

page_text: boat:
constructed according to my invention and shewn applied to the gunwale of a
Figure 2 is a side elevation of the same:
Figure 3 is an end elevation, the gunwale of the boat being shewn in transverse
section.
Similar letters in all the figures indicate similar parts.
a, a¹ are the two arms constituting the carrying frame, and 6 is the joint which
connects them at their outer ends at the point where the row-lock c is carried on a
spindle a fixed to the arm a'.
e is the socket attached to the gunwale A of the boat, in which socket fits and
works a pin on the inner end of the arm a.
gis a dovetail-shaped pin on the inner end of the arm a', which pin fits into the
correspondingly shaped clip consisting of a plate fixed to the gunwale A and
provided with a fixed jaw i and a sliding jaw j, operated by means of a regulating
screw having a milled head 7. The sliding jaw j is formed with slots m, m working
over guide-pins n, n on the plate h.
The socket e can rotate in the plate o by which it is secured to the gunwale A.
2 is the eccentric head at the end of the pin ƒ of the arm a, 'which eccentric can
be loosened or fixed by turning the screw 7, and when loosened can be rotated so as
to retain the pin in the socket e.
When the row-lock carrying frame is in use, the arms a and a extend outwards
from the gunwale A of the boat, and their pins fand g are located respectively in
the socket e and clip hj, which latter is tightened up by means of the screw k, as
shewn by the full lines in Figures 1, 2 and 3.
In order to unship the frame it is only necessary to release the ping of the arm a¹
from the clip by opening the jaws i and j by means of the screw ; to fold the
arms a and a together, as shewn by the dotted lines in Figure 1; and to rotate the
arm a and its socket so as to bring both arms inwards over the gunwale A, when
they can be turned down so as to lie against the inside of the boat, as shewn in
Figures 2 and 3, the rotation of the socket e in its plate o allowing of this latter
movement.
In some cases where long outrig frames are employed I find it advantageous.to
use in connection with each frame a third arm. This third arm is jointed
to the outer ends of the arms hereinbefore described and at its inner end is
supported against the side of the boat so as to form a strut or support for
the frame.
1.1
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
1. A folding row-lock carrying frame for outrigged boats consisting essentially
of two arms jointed at their outer ends at the point where the row-lock is carried,
a rotatable socket in which one of the arms fits and works, and a clip adapted to
receive and secure the other arm, the said socket and clip being fixed to the gunwale
of the boat, substantially as herein before described with reference to the accom-
panying drawings.
2. The improved folding row-lock carrying frame for outrigged boats hereinbefore
described and illustrated in the accompanying drawings.
