GEORGE HENRY RAYNER of 36 Great James Street London, W.C. Architect I do
hereby declare the nature of my said invention to be as follows:-
These Improvements relate to the construction of retaining catches for doors, that
are acted upon by the opening or closing action of the door, and by such action tho
door is kept open or closed at any desired angle until such retaining catch or catches
are released from holding such door.
By these contrivances retaining catches are constructed, which by the action of the
door are opened to receive the door, and by the same action are closed or brought
into position to retain the door, in any desired position.
The first part of my said Improvements consist in constructing a fixing plate with a
slot or hole in it, and on this plate a catch is mounted, the inside of which catch is
formed of three sides of a square to receive the door, and on this catch there is a
projection on that part of it that rests on the fixing plate, and this projection works in
the slot or hole in such fixing plate, and determines the distance that such catch shall
move to open and close; the said catch working on a stud bolt or pin fixed on such
fixing plate. By this arrangement the door opens the catch to receive it, and by
acting on the side of the square on the inside of such catch, that is in line with the
edge of the fixing-plate closes the catch on the door, and thus retains the door in the
desired position.
The second part of my said Improvements consists in constructing the catch with
two arms at a given angle from a centre point, which centre point is the centre of a
pin or bolt fixed to a fixing plate, having a slot in it to receive a projection that is on
such catch, at or about the centre on which it works, one of the arms of the catch is
formed for the door to act on, the other arm is curved inwards as a hook to take into a
eye bolt, that is fixed to the door, by this arrangement the door when opened or closed
to the desired angle, acts on the plainarm of the catch, and by this action moves the
hooked formed arm of the catch into the eye bolt on such door, and so retains the
door in the desired position.

page_text: In order that the nature of my said Improvements may be more fully understood,
I will proceed to describo the several figures on the sheet of drawings hereunto
annoxed, all of which figures are marked with the like letters of reference throughout
to the like parts.

COMPLETE SPECIFICATION.
Improvements in Retaining Oatches for Doors.
I GEORGE HENRY RAYNER Architect & Surveyor of 36 Great James Street
Bedford Row, 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:-
These improvements relate to the construction of retaining catches for doors of
every description, including casement doors, and window sashes. These retaining
catches are arranged to be actuated by the opening and closing action of the door,
and by such action are kept open or closed at any desired angle, until such retaining
catches are released from so holding such doors.
By these contrivances retaining catches are constructed that by the action of the
door or window are opened to receive such, and by the same action are also closed or
brought into position to retain such door or window in the desired position. For
some purposes such catches are arranged to open or close on the door or window by
the hand with or without keys, or knob, or handle; to push, pull, or rotate, and with
or without releasing latches attached thereto.
The first part of my said improvements consist in constructing a fixing plate with a
slot, or hole, or groove in it, for a given distance in a given direction, and on this

page_text: fixing plate a catch is mounted to work on a stud pin or bolt, that is fixed to such
fixing plate, the inside or gripping faces of this catch are formed by three sides of a
square, to receive the butting edges of the door, or fillet that may be attached thereto,
and on this catch there is a projection or pin on that part of it that rests on the fixing
plate, and this projection works in the slot or groove made in the fixing plate, to
determine the distance at which such catch shall open and close, and the hole in this
catch for the pin on which it rotates or moves, is fixed in, or about in a line with, the
centre side of the three sides of a square forming the inside or gripping sides of
such catch.
By these arrangements the action of the door when closing opens the catch to
receive the door, and then acts on the inside square of the catch that is in a line with
the edge of the fixing plate, to close the catch on the door, to retain such in the
desired position.
AL
The second part of my said improvements is a modification of the first part herein
before described, and is applicable to all kinds of doors where such catches are to act
as locks, independent of any other lock or fastener, and consists of attaching one end
of a rod or lever to a part of the catch, by means of a pin or otherwise, and having a
knob or handle attached to the other end of such rod or lever, for the purpose of
moving the catch and releasing the door to allow such to open: the knob or handle
motion being arranged for push, pull, or rotary motion, or such catch to be moved to
release the door by a key, acting direct on the catch to anove it, or on a disc with
pin or projection on it, to move the catch and release the door. The third part of my
said improvements is a further modification, and consists of constructing the catch
with two arms, at a given angle from the centre of the pin on which it works, and
which is secured to the fixing plate, one of the arms of the catch is formed for the
door to act on, and the other arm is curved inwards in the line of motion as a hook to
take into an eye-bolt that is fixed to the door. By this arrangement the door when
opened or closed to the desired angle acts on the plain arm of the catch, and by this
action moves the catch, and the hook formed on the end of the other arm of the catch
enters the eye-bolt on the door, and retains the door in the desired position.
When any of such retaining catches are applied to retain doors, or casement or
sash windows, closed, the fixing plate is secured to the shelf, or door, or butting
door, or butting casement or sash, or to the framing around such door, casement or
sash window, in a line with the door, or casement or sash window when closed; and
when applied to retain doors open such fixing plates are secured to the floors, skirting,
walls, or framing according to convenience.
In order that the nature of my said improvements may be the more fully under-
stood, I will proceed to describe the several figures on the sheet of drawings
hereunto annexed, all of which figures are marked with the like letters of reference
throughout.
Figure I is a perspective view of a retaining catch constructed according to the
first part of my said improvements, A is the fixing plate having the slot B therein,
and C is the retaining catch mounted on the fixing plate A, and D, E, F are three
sides of a square which form the gripping part of the catch C, and which grips over
the door or fillet attached thereto, the centre side being E and the side F is that on
which the door acts to close the catch C, on the door or fillet, and H is the projection
on the catch C that works in the slot B formed in the fixing plate A, that determines
the distance the catch C shall move, and I is the pin or pivot fixed on the fixing
plate A on which the catch C works.
Figure 2 is a perspective view of a modification of Figure I, shewing a projection K
on the side of the catch C, to release the catch from the door.
Figure 3 is a perspective view of a further modification of Figure I, in this
arrangement the slot B is dispensed with in the fixing plate A, the projection H on
the catch C being formed to act on the outer edge of the fixing plate A, and a fillet
piece L is formed to fit the gripping part of the catch C, for such catch to close on
instead of closing on the door, such fillet piece being fixed to the door.
Figures 4 and 5, are perspective views of further modifications of Figure I.

page_text: Figure 6 is a perspective view of a retaining catch constructed according to the
second part of my said improvements. In this arrangement the slot B in the fixing
plate A, and the projection H on the catch C are dispensed with, the retaining catch
in this arrangement being released by means of the lever M, that works on the pin N
as a pivot, that is fixed to the fixing plate A, one end of the lever M working in the
recess P in the end of the catch C to release such catch.
Figure 7 is a perspective view of a modification of Figure 6, and Figure 8 is a
perspective view of the form of the catch only, that is used in Figure 7. In this
arrangement one part of the lever M acts as a cam at R on the projection K of the
catch C, and S is a tightening spring.
Figure 9 is a perspective view of a further modification of Figure 6. In this
arrangement a key T is employed to release the catch, and U is a raised projection
on the catch C for the key T to act upon.
Figure 10 is a perspective view of a retaining catch constructed according to the
third part of my said improvements, in which V is the arm of the catch C that is
acted upon by the door, to move the catch and bring the other arm of the
catch W (the end of which is formed as a hook) into the eye-bolt Y that is fixed to.
the door.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim-
1st. The construction of retaining catches that work on a pin or bolt for a pivot,
that is arranged in a line with, or about in a line with, the face of the centre side of
the three sides of a square, forming the gripping sides of such retaining catches; such
retaining catches being opened to receive the door or sash by the action of the door
or sash, and by the same action are also closed to grip the door or sash and retain the
same in the desired position, as herein before described and set forth.
2nd. The arrangement of such retaining catches to be released from retaining
doors or sashes by means of levers, pins, or keys as hereinbefore described and
set forth.
