of this invention to be as follows:-
The
This invention is designed for the purpose of fastening doors, windows, and the
like independently of an ordinary lock or other means of fastening and is adapted
to be carried about and applied to any of the objects as required. It is particularly
suitable for travellers for use on hotel doors, rattling windows and the like.
device consists substantially in a plate provided with means such as one or more
projections for attaching it to the door frame, and so arranged that it may be
placed in position when the closing of the door will force the points into the wood
work and thus secure this portion of the apparatus. In connection with plate
No. 1 is another plate preferably pivotted to No. 1 and so arranged that it can be
placed parallel with No. 1 or at an angle. In using this apparatus the first plate
is as already explained secured to the door frame and cannot be removed therefrom
until the door is opened; the second plate is then turned on its pivot or otherwise
placed in its proper position, say folded down until it abuts against the door so that
with the plates in this position the door cannot be opened. A pin or other fastening
may be secured by a chain and adapted to pass through holes in both plates or
otherwise prevent the second one from being turned or moved away from the
first.
The second plate may with advantage be provided with a screw or other means
for varying its length so that it may always come conveniently against the face of
the door and both plates may be provided with knobs projections or the like by
which they can be fixed and operated.
As in some cases there may be considerable space between the door and the
frame a third plate or equivalent may be used and may be pivotted between the first
and second plates and so arranged that it will lie between the first plate and the
edge of the door thus filling the space and preventing the first plate from being
improperly withdrawn.

Improvements in Fasteners for Doors, Windows, and the like.
5 A communication from JOHN CAMPBELL, of Villafield, Cardross, Glasgow, in the
County of Lanark, Marine Engineer, at present upon the 5.s. Headlands, now
on a voyage from Cardiff to Port Said.
I, ALFRED JULIUS BOULT of 323 High Holborn, in the County of Middlesex,
M.I. Mech. E., and Chartered Patent Agent, 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 is designed for the purpose of fastening doors, windows, and the
like independently of an ordinary lock or other means of fastening and is adapted
Price Q1'1,

page_text: to be carried about and applied to any of the objects as required. It is particularly
suitable for travellers for use on hotel doors, rattling windows and the like. The
device consists substantially in a plate provided with means such as one or more
projections for attaching it to the door frame, and so arranged that it may be
placed in such a position that the closing of the door will force the projections into
the wood work and thus secure this portion of the apparatus. In connection with
plate No. 1 is another plate preferably pivotted to No. 1 and so arranged that it
can be placed parallel with No. 1 or at an angle. In using this apparatus the first
plate is as already explained secured to the door frame and cannot be removed
therefrom until the door is opened; the second plate is then turned on its pivot or
otherwise placed in its proper position, say folded down until it abuts against the
door so that with the plates in this position the door cannot be opened. A pin or
other fastening may be secured by a chain and adapted to pass through holes in
both plates or otherwise prevent the second plate from being turned or moved
away from the first.
The second plate may with advantage be provided with a screw or other means
for varying its length so that it may always come conveniently against the face of
the door and both plates may be provided with knobs projections or the like by
which they can be fixed and operated.
As in some cases there may be considerable space between the door and the
frame a third plate or equivalent may be used and may be pivotted between the first
and second plates and so arranged that it will lie between the first plate and the
edge of the door thus filling the space and preventing the first plate from being
improperly withdrawn.
In the accompanying drawings:-
Figure 1 is a back end elevation of a fastener constructed according to this
invention.
Figure 2 a plan, and
Figure 3 a perspective view.
Figure 4 is a perspective view showing the fastener applied to a door for holding
said door in its closed position.
Like letters indicate like parts throughout the drawings.
A is the plate formed with the projections or claws A' for attaching it to the
door frame B, Figures 2 and 4. C is the plate pivotted at C to the plate A and
preferably formed with the arm or projection C in which the screw D is adjustable ;
the screw D is formed with a milled head D¹ or equivalent to enable it to be
readily turned by hand and at its inner end is provided with a loose washer or
head D² which is adapted to bear against the door, window or other device to be
retained in its closed position. E is the plate pivotted at C¹ between the plates A
and C and which at its operative end may be tapered or wedge shaped in one or
preferably as shown in Figures 1, 3 and 4 in both directions.
F is a collar mounted loosely on the screw D and to which is attached the
chain F connected to a split pin or equivalent F which is capable of insertion in
the holes F in plates A E and C in the manner shown in Figures 1, 2 and 4 so as
to secure these plates in their parallel positions.
In using this apparatus the plate A when the door is open, is placed against the
door frame B Figure 2 with the claws or projections A¹ presented to the frame,
and the plates E and C turned upon the pivot C¹ out of the way. The door is
then closed, the claws A¹ being thereby forced into the door frame in the manner
shown in Figure 2. The plate C C2 may then be moved to its horizontal position
or alongside the plate A as in Figures 2 and 4 and the pin F may be inserted in
the holes F of the plates A and C, to prevent C from being moved out of the way.
The screw D is then turned until it bears against the door when the door will be
secured in its closed position. Should there be more space between the edge of
the door and the door frame than the thickness of the plate A there might be a
possibility of the claws A' being drawn out from the door frame B by pressure on
the door and to prevent this the plate E is provided, this being only necessary for

page_text: When the
use when such a contingency is to be met. To use the plate E it is simply necessary
before tightening the screw D against the door G to turn the plate E on its pivot C
so as to come between the plate A and the edge of the door G as shown in
Figures 2 and 4 thus preventing the claws from being withdrawn, the tapered form
of the operative end of the plate E rendering this operation easy.
plates A E and C have thus been placed beside each other the pin F is inserted in
the holes F3 thereof, though if the space between the edge of the door G and the
door frame B be too small to admit of the plate E being placed in the same plane
as A and C the pin F may be left out of the holes F³.
The before described device instead of having only one plate such as E may be
provided with two or more plates or in some cases the device may be constructed
without even one plate E and besides being applicable for fastening doors, and the
like may also be used for fastening windows, and such like apparatus. The device
also instead of being provided with a screw for tightening the fastening as before
described may be provided with a wedge or equivalent for insertion between the
faces of the door G and plate arm C, and moreover if desired the plate arm C³
may be dispensed, with under which construction the plate C would preferably be
sufficiently thick to extend in front of the face of the door; this arrangement
however is not considered to be so satisfactory as that before described and,
illustrated in the accompanying drawings.
Having now particularly described and ascertained the nature of this said inven-
tion as communicated to me by my foreign correspondent, and in what manner the
same is to be performed, I declare that what I claim is :-
1. In a fastener for doors windows or the like the combination with a plate such
as A A¹ of a plate such as C substantially as and for the purpose described and
illustrated in the accompanying drawings.
2. In a fastener for doors windows or the like the combination with a plate
such as A A' and plate such as C C² of a screw D adjustable in the plate C C'
substantially as described and illustrated in the accompanying drawings.
3. In a fastener for doors windows or the like the combination with plates such
as A A and C of one or more plates such as E substantially as described and
illustrated in the accompanying drawings.
4. The combination and arrangement of parts constituting the complete fastener
for doors windows or the like substantially as described and illustrated in the
accompanying drawings.
