Improvements in Bolts for Securing Doors, Window-sashes, Case-
ments and Shutters, and for other like Purposes.
We SAMUEL CLEMENT SOUTHAM of Elmhurst, Shrewsbury in the county of
Shropshire Wine and Spirit Merchant and JOHN DOWNES SOUTHAM of Linslade,
Shrewsbury in the aforesaid county also Wine and Spirit Merchant do hereby declare
the nature of this invention to be as follows:-
:-
Our invention relates to bolts employed for fastening or securing doors, window-
sashes, casements and shutters and for other like purposes.
We will first describe our invention as applied to a bolt employed for fastening or
securing a door.
We form in the door a hole which at one end communicates with a slot or opening
leading to one surface of the door. In the said hole we place the bolt which we
provide with a part connected to the said bolt by a hinge or joint the said part being
situate in the slot or opening before mentioned.
When the part above mentioned is turned at an angle to the bolt it serves as a
handle by means of which the bolt may be pushed into or withdrawn from a hole or
opening formed in the jamb or frame or other part by which the door is surrounded. When
the bolt is protruded into the hole in the jamb or frame or other part by which the door
is surrounded the part connected to the bolt is turned so as to be in line with the bolt
and so that it will act as a filling piece or prop against the end of the hole in which
the bolt is mounted and thus prevent such bolt from being withdrawn from the hole
in the jamb or frame or other part by which the door is surrounded. The slot or
opening above mentioned we form upon the "inside" of the door and to further
assist in preventing the bolt from being slidden to allow the door to be opened.
provide such slot or opening with a suitable cover.

Instead of mounting a bolt constructed and arranged according to our invention, in
the door, we in some cases mount such bolt in the jamb or frame or other part adjacent
to the door and in such cases the bolt will be made to pass into a hole formed in the
door at such times as the door is to be fastened or secured.
Although we have above described our invention as applied to a door we would have
it understood that our invention is applicable to bolts for securing window-sashes,
casements, and shutters and for other like purposes.
In another method of carrying our invention into effect, instead of forming the hole
and slot or opening above mentioned in the door or in the jamb or frame or other part
by which the door is surrounded or in the frame of the window-sash, casement or
shutter we form such hole and slot or opening in a block or piece or part of wood or
metal which may be secured to the door, door-jamb or frame, window-sash
or casement or shutter or in any other situation in which it may be desired to be
used.

Improvements in Bolts for Securing Doors, Window-sashes, Case-
ments and Shutters, and for other like Purposes.
We SAMUEL CLEMENT SOUTHAM of Elmhurst, Shrewsbury in the County of
Shropshire, Wine and Spirit Merchant and JOHN DOWNES SOUTHAM of Linslade,
Shrewsbury in the aforesaid County, also Wine and Spirit Merchant 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 bolts employed for fastening or securing doors, window
sashes, casements and shutters and for other like purposes.
-
We will first describe our invention as applied to a bolt employed for fastening or
securing a door.
We form in the door, a hole which at one end communicates with a slot or opening
leading to one surface of the door. In the said hole we place the bolt which we
provide with a part connected to the said bolt by a hinge or, joint, the said part being
situate in the slot or opening before mentioned. When the part above mentioned is
turned at an angle to the bolt it serves as a handle by means of which the bolt may be
pushed into or withdrawn from a hole or opening formed in the jamb or other part by
which the door is surrounded. When the bolt is protruded into the hole in the jamb
or frame or other part by which the door is surrounded the part connected to the bolt
is turned so as to be in line with the bolt and so that it will act as a filling-piece or
prop against the end of the hole in which the bolt is mounted and thus prevent such
bolt from being withdrawn from the hole in the jamb or frame or other part by which
the door is surrounded. The slot or opening above mentioned we forun upon the
inside of the door and to further assist in preventing the bolt from being slidden
to allow the door to be opened we provide such slot or opening with a suitable
cover.
Instead of mounting a bolt constructed and arranged according to our invention,
in the door we in some cases mount such bolt in the jamb or frame or other
part adjacent to the door and in such cases the bolt will be made to pass into a
holo formed in the door, at such times as the door is to be fastened or secured.
Although we have above described our invention as applied to a door we would
have it understood that our invention is applicable to bolts for securing window-
saslies, casements and shutters and for other like purposes.
In another method of carrying our invention into effect, instead of forming the
hole and slot or opening above mentioned in the door or in the jamb or frame or
other part by which the door is surrounded or in the frame of the window-sash,
casement or shutter we form such hole and slot or opening in a block or piece or
part of wood or metal which may be secured to the door, door-jamb, or frame,
window-sash or casement or shutter or in any other situation in which it may be
desired to be used.
a
Our invention is illustrated by the accompanying drawing in which Fig. 1 shows
"bolt" constructed according to our invention and separated from the door,
window-sash or casement or shutter in conjunction with which it is to be used.
Fig. 2 shows in elevation a portion of a door to which a bolt constructed
according to our invention is applied. Fig. 3 shows a horizontal section of a door in
which the bolt is shown withdrawn from the door-jamb and Fig. 4 shows a horizontal
section of a door in which the bolt is protruded into the door-jamb.
The same letters of reference are applied to corresponding parts in all the figures of
the drawing.
The bolt A is formed of two portions a and b the portion b being so hinged or
jointed to the portion a that such portion can be turned at right-angles to the
portion a as indicated by the dotted lines C. We form in the door ca hole d
extending from the edge of the door adjacent to the jamb e towards the opposite
edge of the door c. The hole d must be made as deep as the portion a of the

page_text: b
bolt A, is long. From the surface c¹ of the door c to the hole d, we form a slot
or opening f, the length of the slot or opening f being the same as the length of
the portion 6 of the bolt A. The bolt A is inserted in the hole d formed in the door
and is so placed therein that the portion b of the bolt A will be situate opposite the
slot or opening and that the portion may be turned into such position that the end b¹
of the portion b may serve as a handle by means of which the bolt A may be moved
longitudinally. When the door is to be "bolted" the holt A is pushed longitudinally
in the direction indicated by the arrow B until the end a' of the bolt A passes into
the hole I formed in the jambe of the door c thereby preventing the door c
from being opened. After the bolt has been caused to pass into the hole
portion is turned so as to be in a line with the portion a and form a
"filling-
piece or "prop" which by abutting against the end d¹ of the hole d will prevent
the end a of the bolt A from being withdrawn from the hole g in the door-
jamb e. The slot or opening we form upon the "inside" of the door and to
further assist in preventing the bolt A from being slidden to allow the door to be
opened we provide the slot or opening with a suitable cover indicated by the "dot
and dash" lines h¹.
the
To facilitate the turning of the portion 6 of the boit A upon the portion a of
such bolt A we provide the portion of the bolt A with a knob b' by means of
which when desirable the portion of the bolt A may be readily turned so as to
be at right-angles to the portion a of such bolt A.
Although we have shown the bolt A as being of a circular cross section such bolt A
inay be made of any other suitable cross section, the hole d in which it is placed being
male of a corresponding form.
If it be desired the hole d in which the bolt A is mounted and slidden may be
"lined
with metal.

or
"
Bolts constructed according to our invention may be applied to prevent as may be
desired, egress or ingress at a door, window or casement or for analogous purposes,
the slot or opening being so placed that the purpose for which the bolt is employed
may be accomplished and so that the door, window-sash or casement can only be
opened "from the side desired.
"
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we, declare that what we
claim is
=
For securing doors, window-sashes, casements and shutters and for other like
purposes; a bolt such as that hereinbefore described which is mounted and capable
of being slidden longitudinally in a hole provided with a slot or opening such
as fand is formed in two portions such as a and b one of which being turned at an
angle to the other, at times may serve as a handle by means of which the bolt A may
be slidden and being turned into line with the other portion act as a "filling-piece" or
prop" to prevent the bolt A from being withdrawn to allow the door, window-sash,
casement, or shutter to which it is applied, to be opened.
