AN IMPROVED FASTENER FOR WINDOWS AND DOORS
Year: 1881

page_text: LETTERS PATENT to John Stables, of Eldon House, Longsight, in the County
of Lancaster, for an Invention of "AN IMPROVED FASTENER FOR WINDOWS
AND DOORS."
PROVISIONAL SPECIFICATION left by the said John Stables at the Office
of the Commissioners of Patents on the 5th January 1881.
JOHN STABLES, of Eldon House, Longsight, in the County of Lancaster.
"AN IMPROVED FASTENER FOR WINDOWS AND DOORS."
I make use of a small box or case through which a bolt is passed; one end of this
bolt is provided with antifriction rollers or an antifriction roller, and at the other
end is a knob or handle; on this bolt is a spiral or other spring inside the case; one
end of the spring bears against the end of the case, and the other end of the spring
bears against a shoulder on the bolt to press forward the end on which are the anti-
friction rollers. When this fastener is applied to a window the case is fixed on top
of the inner (lower) sash at the side, the bolt passing into a recess in the outer
sash when the window is shut; to open the window the knob or handle on the
bolt is drawn back and the sash raised; in the outer sash I make any desired
number of recesses for the bolt to fit into, so that the window may be fixed open to
any extent required; the antifriction rollers or roller at the end of the bolt allow
it to slide easily on the outer sash when the window is being opened or closed.
When I apply my improved fastener to a door I use a spring retaining catch to
keep the bolt inside the case when not required. This fastener may be applied to
a sliding door in the same way that it is applied to a window. I make a recess in
the bolt near the handle that locks the bolt when it is shot by catching on the end
of the case.
When a window to which this improved fastener is applied is shut
it is always secure and cannot be opened from the outside.

JOHN STABLES, of Eldon House, Longsight, in the County of Lancaster.
AN IMPROVED FASTENER FOR WINDOWS AND DOORS."
I make use of a small box or case through which a bolt is passed; one end of
this bolt is provided with antifriction rollers or one antifriction roller or a pulley,
and at the other end is a knob or handle; on this bolt is a spiral or other spring
inside the case; one end of the spring bears against the end of the case, and the
other end of the spring bears against a shoulder on the bolt to press forward the
end on which are the antifriction roller, rollers, or pulley. When this fastener is
applied to a window the case is fixed on top of the inner (lower) sash at the side,
the bolt passing through a plate into a recess in the outer sash when the window
is shut; to open the window the knob or handle on the bolt is drawn back and
the sash raised; in the outer sash I make any desired number of recesses for the 1
bolt to fit into, so that the window may be fixed open to any extent required; the
antifriction rollers, or roller, or pulley at the end of the bolt allow it to slide easily
on the outer sash when the window is being opened or closed. When I apply my
improved fastener to a door I use a spring retaining catch to keep the bolt inside the
case when not required. This fastener may be applied to a sliding door in the
same way that it is applied to a window. I make a recess in the bolt near
the handle that locks the bolt when it is shot by catching on the end of the case.
When a window to which this improved fastener is applied is shut it is always
secure and cannot be opened from the outside.
And in order that my Invention may be fully understood and readily carried
into effect I will describe the accompanying Sheet of Drawings, reference being
had to the Figures and letters marked thereon.
Fig. 1 shows a side elevation of my improved fastener applied to a window sash,
and Fig. 2 shows an end view of the same. a is the upper sash of the window
and b is the lower sash, on the top of which is fixed the fastener; c is the case;
d is the bolt, which is drawn back when it is desired to open or close the window
by the ring e which is passed through one end of the shank of the bolt; the other
end or head of the bolt is fitted with a roller which allows it to run smoothly over
the upper sash when the window is being opened or closed; on the bolt shank is
a spiral spring bearing against the back of the bolt head and against the end of the
which spring presses the bolt forward and causes it to enter the recesses
formed in the upper sash. I fit plates f, as shown on Fig. 1, or a single plate with
more than one hole in it, as shown on Fig. 2, on the upper sash where the recesses
are made.
case,
-
Fig. 3 is an elevation in section of my improved fastener; in one end of the
shank is a recess g into which the end of the case enters when the bolt is shot
forward, and the bolt is thus locked and cannot be moved back to allow the
window to be opened without raising the shank to disengage the recess from the
end of the case; h is a pin which is passed through the shank when the bolt is
drawn back to retain it, so that the window may be opened or closed at will.
.
Fig. 4 is a plan of my improved fastener, the bolt of which is furnished with a
pulley on which is an india rubber washer.
Fig. 5 shows a bolt for my improved fastener on which two rollers are mounted.
Fig. 6 is a front view, and Fig. 7 is a side view of a box casting to retain the
bolt when the fastener is fitted to the middle of the window.
Although I have shown my improved fastener fitted at the side of a window, it
may be placed in the middle, in which case I use a casting, see Figs. 6 and 7,

page_text: naving one or more holes for the bolt, and I fix the said casting on the upper sash.
When I apply the fastener to an ordinary door I fix the fastener on the door and
make the recess in the door post. I use a spring or other catch to lock the bolt
when it is shot and when it is drawn back.
When the fastener is applied to a sliding door the recesses to receive the bolt
may be formed in the beam or sill at the top or bottom of the door.
Having stated the nature of my Invention and described the manner of
performing the same, I wish it to be understood that I do not limit myself to the
details herein shown and described, as they may be varied or modified without
departing from my Invention, and I declare that I claim,-
The improved fastener, substantially as and for the purpose herein shown and
described.
In witness whereof, I, the said John Stables, have hereunto set my hand'
and seal, this Second day of July, One thousand eight hundred and
eighty one.
