Improvements in or relating to Bolts for Locking Windows, Doors or
the like.
I, JOSEPH MANTON, 75A, Clarence Street, Rotherhithe, London, S.E., Painter,
do hereby declare the nature of this invention to be as follows:
This invention consists of improvements in or relating to bolts for locking
windows, doors, or the like, the object being to reduce the possibility of the bolts
being removed surreptitiously, such as in the case of burglary; ordinary bolts
for doors and windows, being more or less exposed.
In carrying out my invention, I provide a suitable support or guide in which
the bolt slides; this guide and bolt being of a length determined according to
the position in which the bolt is placed, for the purpose of preventing the bolt
being withdrawn. The support carrying the bolt is not placed upon the outside
of the door or window, but carried in the wall, and may be operated by means of
nobs or projections. The locking device, which I prefer to employ consists of
a hinged piece, which is adapted when in its locking position, to prevent the
withdrawal of the bolt, and by rotating the projection by which the hinged piece
is operated, a screw may be caused to engage in a suitable socket; thus preventing
the bolt from being shot back, until the hinged locking piece is removed from
its securing position. It will be seen that by having the bolt embedded or
carried in the wall and being carried in a guide a sufficient length, the possibility
of opening a window or door burglariously, that is by forcing the bolt, is greatly
reduced; as the parts which operate the bolt are removed the required distance
from the probable point of such burglarious attempt.

Improvements in or relating to Bolts for Locking Windows, Doors or
the like.
I, JOSEPH MANTON, 71, Clarence Street, Rotherhithe, London, S.E., late of 75A,
Clarence Street, Rotherhithe, London, S.E., Painter, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-

This invention consists of improvements in or relating to bolts for locking
windows, doors, or the like, the object being to reduce the possibility of the bolts

page_text: being removed surreptitiously such as in the case of burglary, ordinary bolts
for doors and windows being more or less exposed.
In carrying out my invention I provide a suitable support or guide in which
the bolt slides, this guide and bolt being of a length determined according to
the position in which the bolt is placed for the purpose of preventing the bol
being withdrawn. The support carrying the bolt is not placed upon the outsid
of the door or window but carried in the wall and may be operated by means o
nobs or projections. The locking device which I prefer to employ consists o
a hinged piece which is adapted when in its locking position to prevent the
withdrawal of the bolt and by rotating the projection by which the hinged piece
is operated a screw may be caused to engage in a suitable socket, thus preventing
the bolt from being shot back until the hinged locking piece is removed from
its securing position. It will be seen that by having the bolt embedded or
carried in the wall and being carried in a guide of sufficient length, the possibility
of opening a window or door burglariously, that is by forcing the bolt, is greatly
reduced, as the parts which operate the bolt are removed the required distance
from the probable point of such burglarious attempt.
For purposes of illustration I will now refer to the annexed drawings in
which:
Figure 1, is a side elevation shewing my invention applied to a door.
Figure 2, section to enlarged scale through line X Y in Figure 1.
is
a is the bolt which is carried in the support or guide b. This support or
guide is built in or affixed in the wall as shewn. The hinged piece
provided with the screw spindle e which is rotated by the thumb piece f. This
screw spindle e passes through an aperture in the bolt a when required to
secure the bolt a in its locking position, the end of the screw spindle e engaging
in the socket h. When in its open position, the spindle e may if required, pass
through an aperture in the bolt a for securing it therein.
Although I have described my invention applied to a door, it will be readily
seen that there are other positions in which it may be employed.
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 is:-
1. An improved bolt and locking device, substantially as described and illus-
trated herein and for the purpose set forth.
2. In bolts of the class herein described, a guide or support of suitable length,
in which the bolts slide, said guide or support being affixed in or built into the
wall or other suitable position; a hinged piece upon said guide carrying a set
screw or spindle adapted to pass through the aperture in the said bolt, for the
purpose of securing it in its locking or open position; a socket piece for the
reception of one end of the bolt, said bolt being provided with a knob or projection,
for the purpose of operating same, substantially as described and illustrated
herein and for the purpose set forth.
