PROVISIONAL SPECIFICATION.
Improved Construction of Stop Catch for Gates, Doors, Windows,
and the like.
-
I, EDMUND TUCKER ROBINSON, of Cheshunt, Hertfordshire, Coach Builder,
do hereby declare the nature of this invention to be as follows:-
This invention relates to the construction of rods for use alone, or in connection
with plain hinges, or with rat-tail hinges, or the like to be affixed to gate or door
posts, or to window frames in which the sash swings for the purpose of holding the
gate, door, or the window sash in an open condition.
The invention is particularly applicable to field, coach house, stable, and other
gates and doors which can be thrown open after releasing a Norfolk, or other latch,
and be retained in that position, and be easily released for the gate or door to
close after the opening is passed.
I will describe my invention as forming part of a rat-tail hinge. I make the rod
with a tooth somewhat like a ratchet tooth on one side, and with a stop on another
face or side, said rod slides in a socket fixed to the gate, and when the gate is
pushed fully open, the end of the rod strikes against the stop, and by its looseness
of fit at the pivot or hinge joint, the outer end drops, or engages, and becomes
caught and locked over the tooth to keep the gate open.
The tooth is easily released from the socket by a lift, or other movement on the
rod to enable the gate to swing back.
The use of this invention to a huntsman and other on horseback, will be of the
greatest advantage, as he can readily open a gate without dismounting, and as
readily free it for closing again.
Garden, coach house, or other gates or doors, and also windows furnished with
my invention, if the rods have more than one tooth, can be set open to any desired
extent, and be held firmly.

Improved Construction of Stop Catch for Gates, Doors, Windows,
and the like.
1, EDMUND TUCKER ROBINSON, of Cheshunt, Hertfordshire, Coach 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:-
This invention relates to the construction of rods for use alone or in connection
with plain hinges, or with rat-tail hinges, or the like to be affixed to gate or door
posts, or to window frames in which the sash swings for the purpose of holding the
gate, door, ventilator, or the window sash in an open condition.
The invention is particularly applicable to field, coach house, stable, and other
gates and doors which can be thrown open after releasing a Norfolk, or other latch,
and be retained in that position, and be easily released for the gate or door to close
after the opening is passed.

page_text: I will describe my invention as forming part of a rat-tail hinge. I make the rod
with a tooth somewhat like a ratchet tooth on one side, and with a stop on another
face or side, said rod slides in a socket fixed to the gate, and when the gate is
pushed fully open the end of the rod strikes against the stop, and by its looseness
of fit at the pivot or hinge joint, the outer end drops or engages and becomes
caught and locked over the tooth to keep the gate open. The tooth is easily
released from the socket by a lift or other movement on the rod to enable the gate
to swing back.
The use of this invention to a huntsman and others on horseback will be of the
greatest advantage, as he can readily open a gate without dismounting and as
readily free it for closing again.
Garden, coach house, or other gates or doors, and also windows furnished with
my invention if the rods have more than one tooth can be set open to any desired
extent and be held firmly.
My invention will be clearly understood by reference to the annexed drawings.
Figure is a plan view of a field, stable, or other gate with my invention
applied thereto for keeping said gate, or it may be a door in a fully opened or a
closed position, the means of fastening the gate or door in such positions being on
the same hinged bar which constitute my invention, and may be part of the
appliances by which the door can be opened or closed if so desired as by a spring
arrangement.
Figure 2 is a front view of the same appliance as shown at Figure 1.
Figures 3 and 4 are front and plan views of an ordinary rat-tail spring but with
the end extended and provided with my posed catch to engage over the stop on the
runner plate when the gate or door to which such rat-tail spring is affixed has to
be kept in a wide open condition.
.
A is a bar hinged at B to a strap C secured to the gate or door post D.
E, E, are two nosed catches in opposite order. F is a plate secured to the gate or
door G, through an eye H of which plate my nosed bar A has play when the gate
or door is opening or closing.
In the position shown in Figures 1 and 2, the gate or door is in a locked and
closed position by reason of the nose E passing through the eye H of the plate F
and dropping on the outer side of it, which bar A has to be lifted simultaneously
with the gate or door being pushed open for the narrow part 1 of the bar A to
ride in the eye H until the door is fully opened when the plate rides over the
notch El and allows the bar A to drop on the inner face of the eye H to lock the
gate or door in a fully opened condition.
To prevent the door, when in an opened condition, going beyond a certain angle,
such as in a fully opened position, I turn the end of the bar A, as at J Figure 1,
to form a stop so that the gate or door is held firmly between the stop J and the
nose El.
The application of my invention as shown in Figure 1 is, say to a field gate,
such as that which simply closes to by reason of the hinges K being set out of
the vertical, so that a postillion or an equestrian has simply to lift the bar A and
push the gate which can be easily effected by, say, the hunting crop of a huntsman,
and he can either leave the gate, after passing through, to close itself, or he can
push it wide open for other huntsmen, or carriages to pass through, after which by
again lifting the bar A, the gate will close and become locked.
.
I have described this invention, according to Figures 1 and 2, as applied to a
gate or door but it is equally applicable to the back or panel doors of tradesmens
and other carts, as well as to the hinged roofings of- such, the attendant has only
to shift the bar A simultaneously with the push over. or the lift when the door,
counter flap, or hinged roofs such as one finds with bakers and grocers, carts. can
be kept open or closed without throwing a strain upon the. hinge joints as by the
present system where chains are used.
According to Figures 3 and 4 one nose, such as E is necessary on the bar A, the
spring in the box L being sufficient to keep the bar by its roller M in contact for

page_text: riding against the plate and keeping the door in a closed position but which door
can when pushed wide open become locked by the nose E riding over and engaging
with the stop N, as before explained with reference to Figures 1 and 2.
P, P, are guide lips, one of which carries the weight of the bar A, the other
being sufficiently distant to allow the bar A to be lifted for the nose to pass
over the stop N the door G then being free to close under the action of the
spring.
I have shown the nosed catches at the ends of my bars but they may be
at any other convenient part, especially when applied to casement windows, or
ventilators.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The construction and employment of a hinged bar A with one or more nosed
catches E, E', for engaging with an eye H for retaining a gate, door, window,
flap, or the like in an open or closed condition, substantially as set forth.
2. Providing a rat-tail, or equivalent hinge with a nosed catch E to engage over
a stop, such as N, to hold a gate, door, window flap or its equivalent in a fully
opened, or other condition substantially as described.
