AN IMPROVED APPARATUS FOR RAISING LOWERING AND SECURING WINDOW SASHES
Year: 1884

page_text: I, FRANK SMITH of Birmingham in the County of Warwick, Manufacturer do
hereby declare the nature of the said invention for AN IMPROVED APPARATUS FOR
RAISING LOWERING AND SECURING WINDOW SASHES to be as follows:-
The sash being hung in the usual way to one or both sides of the top rail of the
lower sash is attached a metal plate carrying a tube or barrel in which is a bolt to
which is attached a lever arm, A spiral or other suitable spring with the tube or
barrel bearing against the bolt throws it back into position when it has been
turned by the raising up of the lever arm. Upon the end of the bolt projecting
from the barrel is a disc with a projection upon its surface. This projection is for
the purpose of catching or locking into sinkings or notches upon a metal plate
which is placed at the side of the upper sash so, that the projection on the bolt
catching into the plate prevents the sash from being lowered.
The following is the means employed to release the catch, Two cords are
attached to the side of the sash the one being brought down below the lever arm
is passed up through a loop at the end thereof and brought down over it so that
the act of pulling the cord to lower the sash raises the lever and releases the catch,
the other cord is passed over a pulley on the head of the sash frame to raise the
sash in the ordinary way.
Instead of the loop on the lever arm small pulleys may be used for the cord to
pass over.
When it is desired to prevent the sashes from rattling a spring is placed in the
barrel at the back of the bolt causing it to bear against the plate on the other sash
and press the sash against the frame.

page_text: I FRANK SMITH of Birmingham in the County of Warwick Manufacturer do
hereby declare the nature of my said invention for AN IMPROVED APPARATUS
FOR RAISING LOWERING AND SECURING WINDOW SASHES and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement reference being had to the drawings hereunto annexed
and to the letters and figures marked thereon that is to say :-
The sash being hung in the usual way, to one or both sides of the top rail of the
lower sash is attached a metal plate carrying a tube or barrel in which is a bolt to
which is attached a lever arm. A spiral or other suitable spring bearing against
the bolt throws it back into position when it has been turned by the raising up of
the lever arm.
The spiral spring is by preference placed within the tube although
it may be placed outside or a flat or other spring may be used if desired when it
has been turned by the raising up of the lever arm, Upon the end of the bolt
projecting from the barrel is a disc with a projection upon its surface, This
projection is for the purpose of catching or locking into sinkings or notches upon a
inetal plate which is placed at the side of the upper sash so that the projection on
the bolt catching into this plate prevents the sash from being lowered.
The following is the means employed to release the catch. Two cords are
attached to the side of the sash the one being brought down below the lever arm,
is passed up through a loop at the end thereof and brought down over it or it may
be simply passed down and through the loop so that in either case the act of
pulling the cord to lower the sash raises the lever and releases the catch. the
other cord is passed over a pulley on the head of the sash frame to raise the sash
in the ordinary way, Instead of the loops on the lever arm small pulleys may be
used for the cord to pass over. When it is desired to prevent the sash from
rattling a spring is placed in the barrel at the buck of the bolt causing it to bear
against the plate on the other sash and press the sash against the frame.
Referring to the drawings Fig 1. shews a sash window with the apparatus
attached Fig 2. is an enlarged view of one side of the upper sash and Fig 3. a
section through the same Fig 4. represents the bolt or catch for securing the
sash. a.
Figs 2. 3 and 4. is the metal plate carrying the barrel b. which contains a
bolt,the back of which is shewn at c. To this portion of the bolt is attached the
lever arm d. Upon the end of the bolt c. is the disc e. (shown by the dotted line)
projecting from the barrel b. and having upon its surface the projection. f.
When the barrel is fixed into position as shewn in figures 1. 2 & 3 this
projection f. catches into the notches (g. g¹) upon the metal plate which is fixed to
the upper sash as shewn in the drawings one of these notches. g. is to receive the
catch and fasten the window when it is closed and other notches g'. are to receive
the catch and fasten the window when it is open.
To release the catch the two cords h & (i) are attached as shewn to the side of
the sash, the cord is brought down below the lever arm d. passed down through
the loop at the end of it and brought down over it and terminated with the
handles j. . Fig 1. so that the act of pulling the handles j. to lower the sash raises
the lever arm d. thereby turning the bolt c. and releasing the catch f. and allowing
the sash to slide down The cord i. is passed over the pulley 1. to raise the sash by
pulling the cord by the handles k.

page_text: 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,
The peculiar form of barrel bolt and catch described and illustrated for the for
the purpose of fastening the sashes of windows and the arrangement of cords for
the purpose of lowering the upper sash whilst actuating the said bolt as herein set
forth and described.
