A communication from WILLIAM EDWARD THOMAS, of Johannesburg, in the South
African Republic.
I, ARTHUR FREEMORE SPOONER, of 323, High Holborn, in the County of London,
Chartered Patent Agent, do hereby declare the nature of this invention to be as
follows:-
This invention relates to fastenings for doors, windows and the like and comprises
the improved device hereinafter described.
At or
According to the said invention an L-shaped piece of metal is provided, the
short, or one, arm of which is intended to be let into the frame into which the door
or the like fits when closed, or between the window sashes, and to be firmly secured
in position by screws, nails, or the like. The other or long arm of the said L-shaped
piece rests against the front part of the frame or sash rail so that its inner surface
is in line with that of the door or other sash, when the latter is closed.
about the apex of the said L-shaped piece is a pivoted piece which, when the door
or the like is closed and it is desired to fasten or secure the same, can be turned
over or outwardly so as to bear against the side rail of the said door, or the like;
and thereby to hold it firmly in position, a spring or other catch mounted on the
long arm engaging with a projection upon the said pivoted piece, and preventing the
return thereof until released to admit of the said door or the like being opened.
.
When the above mentioned spring catch is disengaged from the extension upon
the pivoted piece it slides upon a curved surface upon the other side of the said
extension, and the said pivoted piece can be folded back, or shut up so as to be out
of the way of the door, or the like, and will be retained in that position by the said
spring catch.
Provision may be made for securing the long arm of the above mentioned
L-shaped piece to the frame, as well as the short or other arm thereof, by screws
or their equivalents; or the short or other arm thereof may be dispensed with, and
the part carrying the pivoted piece and spring or other catch secured to the said
frame by means of screws or their equivalents.

Improvements in Fastenings for Doors, Windows, and the like.
A communication from WILLIAM EDWARD THOMAS, of Johannesburg, in the South
African Republic.
I, ARTHUR FREEMORE SPOONER, of 323, High Holborn, in the County of London,
Chartered Patent. Agent, do hereby declare the nature of this invention and in what
Price R71

page_text: manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
This invention relates to fastenings for doors, windows and the like and comprises
the improved device hereinafter described.
In the accompanying drawing, which shows how the said invention may be
conveniently and advantageously carried into practice,
Figure 1 is a plan, showing the fastening closed or out of operation,
Figure 2 is a similar view showing the said fastening open or in operation, and
Figure 3 is a side elevation showing details of construction thereof.
Like letters indicate corresponding parts throughout the drawing.
a is an L-shaped piece of metal the short, or one, arm of which is intended to be
let into the frame into which the door or the like fits when closed, or between the
window sashes and to be firmly secured in position by screws, nails, or the like as
seen in Figure 3. The other or long arm of the said L-shaped piece a rests against
the front part of the frame or sash rail so that its inner surface is in line with that
of the door or other sash, when the latter is closed. At or about the apex of the
said L-shaped piece a is a piece b pivoted as indicated at b*, and which pivoted
piece when the door or the like is closed and it is desired to fasten or secure the
same, can be turned over or outwardly as shown in Figure 2 so as to bear against
the side rail of the said door, or the like and thereby to hold the said door firmly
in position. c is a catch adapted to be maintained either in its fully open or
completely closed position by a spring c¹ or otherwise, which spring catch c is
pivoted at c✶ to the long arm of the L-shaped piece a, and is adapted to engage
with one side of a projection 61 upon the said pivoted piece b, and prevent the
return thereof, until such time as it may be released to admit of the said door or the
like being opened.
When the above mentioned spring catch c is opened in the direction indicated by
the arrow 1 in Figure 2 it becomes disengaged from the projection 61 upon the
pivoted piece b. The latter may then be turned towards the position indicated in
Figure 1, and upon the catch c being closed again it slides upon a curved surface b²
upon the other side of the said projection 61, and the said pivoted piece b will then
be shut up into the position shown in Figure 1, so as to be out of the way of the
door, or the like, and will be retained in that position by the said spring catch c.
Provision may be made for securing the long arm of the above mentioned L-shaped
piece a to the frame, as well as the short or other arm thereof, by screws or their
equivalents; or the short or other arm thereof may be dispensed with, and the part
carrying the pivoted piece band spring or other catch c secured to the said frame by
means of screws or their equivalents.
The drawings show the said device attached to a door frame in such a manner as to
be operative upon a door opening in the direction of the arrow 2 in Figure 2.
Obviously if the door opened in the opposite direction or if the fastening were
required to be placed on the opposite side to that on which it is shown in the drawing
the device would be attached to the door instead of to its frame.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is :-
1. A fastening or device for securing doors, windows and the like, comprising an
L-shaped or equivalent piece such as a, a pivoted piece such as b and a catch such as
c substantially as set forth.
2. The improved fastening or device for securing doors, windows and the like
constructed substantially as set forth and as illustrated in the accompanying drawing.
