We GEORGE CHRISTOPHER FIELDER, Joiner of 13 Crossley Street, Clarendon
Road, and RICHARD SIDDALL, Plumber, of 22 Claren lon Road, both of Crumpsall,
near Manchester, in the County of Lancaster, do hereby declare the nature of this
invention to be as follows:-
This invention relates to the construction of an improved lockfast safety bolt for
securing or fastening sash windows.
According to our invention we fix firmly by screws onto the top bar of the
bottom sash, near to one side (say the right hand for example) a metal plate
provided with a fixed strap carrying a bolt which is capable of both turning and
sliding therein. This bolt is provided near to one end with a spur or arm at right
angles thereto, by means of which it can be turned partially round, and also caused
to move or slide horizontally, the latter motion being limited to about of an inch
by one side of the fixed strap and a pin fixed in the plate. Near to the other end
of the bolt is a hinged strap the loop of which is provided with a slot to receive a
pin fixed in the bolt so that when the bolt is shot and the hinged strap is brought
down into its place the pin on the bolt passes through the said slot and locks
the bolt so that it cannot be moved back without first raising the hinged strap.
To the outer edge of the hinged strap which coincides with the front edge of the
sash bar is hung a hinged hasp provided with a slot which comes over a staple
fixed by a screw plate to the front of the sash bar; and it will be evident that if a
bow of a padlock be placed through the part of the staple which projects through
the said basp the bolt cannot possibly be shot back until the padlock has been
unlocked, which can only be done from the inside.
The end of the bolt may pass into a hole in the right band sash stile on one side
of the weight cord, but we prefer to let it lock into a slot formed in a metal plate
fixed thereto so as to allow of the sash being raised a short distance for ventilation
or otherwise, at the same time that it is bolted or secured against further raising.
The arm of the bolt is sufficiently long to pass over the base plate and project into
a similar slotted plate fixed to the inner side of the upper sash, the length of the
slct being such that the upper sash can also be lowered a short distance for
ventilation whilst securely fastened against further opening.

We GEORGE CHRISTOPHER FIELDER, Joiner, of 13 Crossley Street, Clarendon
Road, and RICHARD SIDDALL, Plumber of 22 Clarendon Road, both of Crumpsall,
near Manchester in the County of Lancaster, 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 relates to the construction of an improved lockfast safety bolt for
securing or fastening sash windows.

page_text: The nature of our said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the sheet of drawings hereunto annexed and the following explanation thereof.
Fig. 1 on the drawings is a face view of our improved means for fastening
windows.
Fig. 2 a plan view, and Fig. 3 a vertical section of the same.
According to our invention we fix firmly by screws onto the top bar a of the
bottom sash, near to one side (say the right hand for example) a metal plate b
provided with a fixed strap c carrying a bolt d which is capable of both turning
and sliding therein. This bolt is provided near to one end with a spur or arm e at
right angles thereto by means of which it can be turned partially round, and also
caused to move or slide horizontally, the latter motion being limited to about of
an inch by one side of the fixed strap c and a pin f fixed in the plate. Near to the
other end of the bolt is a hinged strap g the loop of which is provided with a slot
to receive a pin h fixed in the bolt d so that when the bolt d is shot and the
hinged strap g is brought down into its place the pin on the bolt d passes through
the said slot and locks the bolt so that it cannot be moved back without first raising
the hinged strap g.
To the outer edge of the hinged strap which coincides with the front edge of the
sash bar a is hung a hinged hasp i provided with a slot which comes over a staple k
fixed by a screw plate to the front of the sash bar a and it will be evident that if
the bow of a padlock be placed through the part of the staple & which projects
through the said hasp the bolt d cannot possibly be shot back until the padlock
has been unlocked, which can only be done from the inside.
m
The end of the bolt may pass into a hole in the right hand sash stile / on one side
of the weight cord, but we prefer to let it lock into a slot formed in a metal plate
fixed thereto so as to allow of the sash a being raised a short distance for ventilation
or otherwise, at the same time that it is bolted or secured against further raising.
The arm e of the bolt d is sufficiently long to pass over the base plate 6 and project
into a similar slotted plate n fixed to the inner side of the upper sash o the length
of the slot being such that the upper rash can also be lowered a short distance for
ventilation whilst securely fastened against further opening.
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 :-
The improved means for securing or fastening windows substantially as herein-
before described and illustrated by the drawings annexed.
