Improved Devices for Holding Open Cabin and other Doors.
.I, FREDERICK JOHN TREWARTILA, Engineer, 54 Selwyn Road, Plaistow, London,
do hereby declare the nature of this Invention to be as follows:-
This Invention relates to retaining links and catches for holding open cabin and
other doors, and it has for its object to so construct these that the objectionable
rattling noise incident to the use of the ordinary hooks is obviated, and the
tendency of the links to work loose in their catches is minimised.
To that end I form the connecting link or rod with a ball at each end, one end
of whch link turns in a socket formed in a bracket attached to the door frame or
other stationary part, the other end being adapted to engage with a spheroidal
or other recess in a catch bracket fixed on the cabin or other door; or the arrange-
ment may be reversed. The link carrying bracket is a single casting and a semi-
spherical recess is formed in it communicating with the back of the bracket so that
the link can thereby be inserted in its socket. A slot extends from the socket to
the front and also to the lower side of the bracket through which the link or rod
passes outwards, said slot permitting of the rod or link being turned down out of
the way when not in use. The catch bracket, which is fixed to the cabin or other
door, is also a single casting with a slot in its front face which ends in a spheroidal
recess, open to the upper side of the bracket. Each of these brackets may be
provided with friction pads of india rubber on the parts against which the balls
of the link or rod bears.
The shape of the link or rod may be modified, in the following manner:-The
socket ball instead of being formed on the link or rod may be secured thereon by a
pin passing through the ball and the rod, or the link instead of being formed as
a straight rod may be bent near one end at right angles to suit the relative positions
of the socket and catch brackets. Further the connecting link may be T-shaped
at one or at either end, a corresponding socket and catch recess being formed in
the socket and catch brackets respectively.
Instead of pivoting the link or rod in a socket the link may be pivoted between
two jaws by means of a removable pin.

I, FREDERICK JOHN TREWARTHA, Engineer, 54 Selwyn Road, Plaistow, London,
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:—
This Invention relates to retaining links and catches for holding open cabin and
other doors, and it has for its object to so construct these that the objectionable
rattling noise incident to the use of the ordinary hooks is obviated, and the
tendency of the links to work loose in their catches is minimised.
a
The Invention is illustrated by the accompanying drawings, Figure 1 being.
side elevation of one modification of the improved device for holding open cabin
and other doors, Figure 2 is an end view and Figure 3 a plan of same. Figure 4
is a plan and Figure 5 an elevation of the catch bracket adapted to be used in
special circumstances, and Figures 6 and 7 are like views of another form of
bracket for the same purpose. Figure 8 shews a modified form of link.
In carrying out the Invention I form the connecting link or rod A with a ball at
each end, one end A¹ of which link turns in a socket B' formed in a bracket B
attached to the door frame or other stationary part, the other end A³ being adapted
to engage with a spheroidal or other recess C in a catch bracket C fixed on the
cabin or other door; or the arrangement may be reversed. The link carrying
bracket B is a single casting and the semi-spherical recess which forms the
socket B' communicates with the back of the bracket so that the link A can thereby
be inserted in its socket. A slot B2 extends from the socket to the front and also
to the lower side of the bracket through which the link or rod passesoutwards, or
slots B3, B4, B5, may also extend as shewn through either of which the rod or link
may pass, said slot or slots permitting of the rod or link being turned out of the
way when not in use. The catch bracket. C which is fixed to the cabin or other
door, is also a single casting with a slot C in its front face which ends in the
spheroidal recess before mentioned, and is open to the upper side of the bracket C.
Each of these brackets may be provided with friction pads of india rubber or other
material on the parts against which the balls of the link or rod bears.
The forms of catch bracket shewn at Figures 4, 5, 6 and 7 are used where the
catch piece may be conveniently supported upon a bracket carried on the door
frame or other stationary part.
The shape of the link or rod A may be modified, in the following manner:-
The socket ball A¹ instead of being formed on the link or rod A may be secured
thereon by a pin passing through the ball and the rod, or the link A instead of
being formed as a straight rod may be bent near one end at right angles as shewn
at A3, Figure 8, to suit the relative positions of the socket and catch brackets and
the end A may be of ball or other form. Further the connecting link may be
T-shaped at one or at either end, a corresponding socket and catch recess being
formed in the socket and catch brackets respectively.
Instead of pivoting the link or rod in a socket the link may be pivoted between
two jaws as shewn at Figure 7 by means of a removable pin D.
Having now particularly described and ascertained the nature of my said

page_text: Invention, and in what manner the same is to be performed, I declare that what I
claim is :-
The improved devices for holding open cabin and other doors constructed
substantially as described with reference to the drawings annexed.
