We, ALEXANDER DEL GUERRA, Oil Skin Manufacturer, and DEMETRIUS STEFFANO,
of No. 160, Buts Road, Cardiff, in the County of Glamorgan, do hereby declare the
nature of this invention to be as follows:-

Our invention relates to improved devices for securing doors, and is more
particularly applicable to inner doors such as those of hotel bedrooms, the normal
fastening devices of which may be considered by a strange occupant as insufficient.
may
The invention consists in the combination of teeth adapted to enter the wood of the
door or door-frame and floor, and adjustable stops or expanding wedges; or the above
devices be used separately if duly modified. We propose to incorporate with, or
in, the devices which we make use of, a gong which is adapted in any convenient way
to sound under the compression exerted upon the device by pushing at the door from
the outside.
The following devices exemplify several methods of putting our invention in
practical form, which methods are to be taken as typical, and not as limiting the
invention.
A bar has teeth formed at one end of it adapted to be forced into the door frame
when the door is closed. A stop is provided at the other end of the bar adapted to
prevent the door being pushed out of the frame. This stop may be a screw nut or an
adjustable pin or a sliding block.
.
The above mentioned bar may be parallel or taper.
When we use a taper bar we propose to utilise its properties as a wedge to the
best possible effect by making it expansible. That is to say, the wedge is made in
two parts which are hinged together at one end and at the other furnished with a
screw device adapted to separate them.

page_text: The toothed bar-device mentioned above may be modified to the extent of substituting
a block of any convenient shape for the bar and be provided with teeth on opposite,
or as many, sides as may be desired.

We, ALEXANDER DEL Guerra, Oil Skin Manufacturer, and DEMETRIUS STEFFANO,
Ship Store Merchant, of No. 160, Bute Road, Cardiff, in the County of Glamorgan,
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:
'
Our invention relates to improved devices for securing doors; and is more
particularly applicable to inner doors, such as those of hotel bedrooms, the normal
fastening devices of which may be considered by a strange occupant as insufficient.
The invention consists in the combination of teeth adapted to enter the wood of the
door and door frame or floor, and adjustable stops or expanding wedges. These
devices may be used if duly modified. We propose to incorporate with or in the said
devices a gong which is adapted in any convenient way to sound under the com-
pression to which the fastener is subjected by pushing the door from the outside.
In order that the invention and the means by which it can be carried into practical
effect may be thoroughly understood, we will now proceed to describe the same in
detail, referring in so doing to the accompanying drawings which are to be taken as
part of this specification and read therewith.
The devices illustrated in the drawings exemplify several methods of embodying our
invention in practical form, but it must be distinctly understood that our invention is
not limited to the particular devices or methods illustrated, inasmuch as they may be
varied, and are put forward as typical illustrations rather than as final forms.
Fig. 1 is a perspective view of a door fastening made according to our invention.
A is a metal plate having fangs a. a, formed at one end. B is a pin, or adjustable
stop, conveniently attached to the plate by a chain; and b, b, are holes formed in the
plate at increasing distances from the fangs.
The plate A
is held against the door frame, with its fangs upon the wood, and the plate projecting
The device made as above described is used in the following manner.

page_text: into the room. The door is then closed. The act of shutting the door into its frame
will cause the fangs a a to enter the latter, and the pin B is next put into the hole b
next to the door. The closed door holds the plate to the frame, the plate holds the
pin up to the door, and the pin prevents the opening of the door.
Fig. 2 is a perspective view of a modification of the invention in respect of the
adjustable stop.
The plate A, instead of having a series of holes formed in it, and a pin B
attached to it, terminates in a screw C provided with a nut c adjustable thereupon.
The end of the screw is provided with a stop c¹ for the purpose of preventing the nut
being screwed off the screw.
Fig. 3 is a perspective view of a modification of the device illustrated in Fig. 2.
The screw C is prolonged as a shank d to admit of the nut c being drawn further away
from the door, for the purpose of allowing plenty of room for opening the latter. The
shank is not necessarily straight, but may be bent away from the door.
The stop nut c is preferable to the stop pin B, inasmuch as by it, the door can be
held immovably in its frame, and rattling efficiently prevented.
The devices illustrated in the figures above described are evidently not applicable to
doors which are hung within, instead of upon the front edge of, the frame; for when
such a door is closed there is no room for either a pin as in Fig. 1. or a nut as in
Figs. 2 and 3. We therefore propose to use for such a door the modification illustrated
in Fig. 4.
D is a second plate adapted by means of clips d to slide upon the plate A.
Each plate has a series of holes b formed in it. The pin B is attached to, preferably,
the second plate. The nose of the second plate is bent as shewn, thereby producing
an adjustable stop E. This is drawn back to allow of the door being shut, and
then pushed up thereto, and pinned there.
The adjustability of the stop E may be secured by a ratchet device, instead of
by the pin device illustrated; or an adaptation of the nut and screw device
illustrated in Figs. 2 and 3 may be used.
The expanding wedge device illustrated in Figs. 5, 6 and 7 can be used instead
of either a pin or nut device.
F, F are two plates hinged together in any, convenient manner along the ends f,
ie., along the apex of the wedge. A knuckle and pin connection is not essential.
It suffices if the top plate F is bent round the lower one F.
The plate F is drilled and tapped at the end furthest from the hinge, i.e., next to
the base of the wedge, to receive a thumb screw G. The nose of the screw is
shouldered down, and terminates in a point g. The point is long enough to pass
through the plate F", and to enter the floor or the frame as the case may be.
The hole in the lower plate is only large enough to admit the point G, so that
the shoulder g will bear upon the plate.
The wedge is closed and pushed between the door and the floor or the frame.
The screw is then turned into the tapped hole in the plate F, and screwed home
until its point has entered the floor or the frame, and the wedge has been expanded
as widely as possible. The inclined face of the top plate will prevent the door
being opened, and so far replaces the various stops herein before described; and
the hold which the point g takes of the floor or frame prevents the wedge being
pushed before the door.
The device illustrated in Fig. 8 consists of two hollow hemispheres h, h armed with
spikes ', a spring i, a gong j, its clapper, and a bolt k fast to one hemisphere and
holding the other by a nut .
The use and operation of this device are as follows. It is placed upon the ground
close up to the door, with the axis of the bolt pointing towards the latter. If the door
is pushed inwards, the spikes ' engage in the door and floor, and the two hemispheres
are pressed together, thereby actuating the clapper, and causing it to strike the gong.
Any suitable device may be made use of for causing the motion of either hemisphere
to bring the clapper forcibly against the gong.

page_text: Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is :—
1. The combination of plate, fangs, and stop, as set forth with reference to.
Figs. 1, 2, 3 and 4.
2. The combination of plate, fangs, and adjustable stop adapted to be used with
doors hung within the frames, as set forth.
3. The combination of expanding wedge, device for expanding it, and stop as.
set forth.
4. The combination of hemispheres and spikes as set forth.
5. The combination of hemispheres, spikes, and gong, as set forth.

Our invention relates to improved devices which are used for securing doors; and is
more particularly applicable to devices used for securing inner doors, such as those of
hotel bedrooms, the normal fastening devices of which may be considered by a strange

A is a metal plate having fange a, a, formed at one end. B is a pin, or adjustable
stop, conveniently attached to the plate by a chain; and 6, b, are holes formed in the
plate at increasing distances from the fungs

will cause the fange-a-a to enter the latter, and the pin B is next put into the hole-b
next to the door. The closed door holds the plate to the frame, the plate holds the
pin up to the door, and the pin prevents the opening of the door.
Fig. 2 is a perspective view of a modification of the invention in respect of the
adjustable stop.
The plate A, instead of having a series of holes b formed in it, and a pin B
attached to it, terminates in a screw C provided with a nut-c adjustable thereupon.
The end of the screw is provided with a stop-c' for the purpose of preventing the nut
being serowed off the seren,
Fig. 3 is a perspective view of a modification of the device illustrated in Fig. 2.
The serew C is prolonged as a shank d to admit of the nut c being drawn further away
from the door, for the purpose of allowing plenty of room for opening the latter. The
shank is not necessarily straight, but may be bent away from the door.
The stop nut is preferable to the stop pin B, inasmuch as by it, the door can be.
hold immovably in its frame, and rattling efficiently prevented.
The devices illustrated in the figures above described are evidently not applicable to
doors which are hung within, instead of upon the front edge of, the frame; for when
such a door is closed there is no room for either a pin as in Fig. 1. or a nut as in
Figs. 2 and 3. We therefore propose to use for such a door the modification illustrated
in Fig. 4 1 is a perspective view of one form of our present improved door fastening
device.
D is a second plate adapted which by means of clips d to can freely slide upon the
plate A. Each said plate has a series of holes 6 formed in it. The pin B is attached
to, preferably, the second plate D. The nose of the second plate is bent as shewn,
thereby producing an adjustable stop E. This is drawn back to allow of the door being
shut, and then pushed up thereto, and pinned there.
The adjustability of the stop E may be secured by a ratchet device, instead of
by the pin device illustrated; or an adaptation of the a nut and screw device
illustrated in Figs. 2 and 3 may be used. may be used for adjusting the plate D.
The expanding wedge device illustrated in Figs. 5, 62, 3 and 7 4 can be used
instead of either a pin or nut device.
F, F are two plates hinged together in any convenient manner along the ends f,
i.e., along the apex of the wedge. A knuckle and pin connection is not essential.
It suffices if the top plate F is bent round the lower one F¹.
The plate F is drilled and tapped at the end furthest from the hinge, i.e., next to
the base of the wedge, to receive a thumb screw G.
The nose of the screw is
shouldered down, and terminates in a point g. The point is long enough to pass
through the plate F", and to enter the floor or the frame as the case may be.
The hole in the lower plate is only large enough to admit the point G, so that
the shoulder g' will bear upon the plate.
The wedge is closed and pushed between the door and the floor or the frame.
The screw is then turned into the tapped hole in the plate F, and screwed home
until its point has entered the floor or the frame, and the wedge has been expanded
as widely as possible. The inclined face of the top plate will prevent the door
being opened, and so far replaces the various stops adjustable stop herein before
described; and the hold which the point g takes of the floor or frame prevents the
wedge being pushed before the door.
The device illustrated in Fig. 85 consists of two hollow hemispheres h, h armed with
spikes h, a spring i, a gong j, its clapper j³, and a bolt k fast to one hemisphere and
holding the other by a nut k¹.
The use and operation of this device are as follows. It is placed upon the ground
close up to the door, with the axis of the bolt pointing towards the latter. If the door
is pushed inwards, the spikes h¹ engage in the door and floor, and the two hemispheres
are pressed together, thereby actuating the clapper, and causing it to strike the gong.
Any suitable device may be made use of for causing the motion of either hemisphere
to bring the clapper forcibly against the gong.

page_text: We would have it well understood that we do not claim by itself a plate A having
fangs and used for the purpose specified but, Having having now particularly described
and ascertained the nature of our said invention and in what manner the same is to
be performed we declare that what we claim is :--
1. The combination of plate, fangs, and stop, as set forth with reference--to
Figs. 1, 2, 3 and 4.
2.1. The combination of plate, fangs, and adjustable stop adapted to be used with
doors hung within the frames, or otherwise as set forth.
