Improvements applicable to Railway Carriage and other Windows,
Sliding Panels, and the like.
I, WILLIAM WRIGHT, of Ashfields. 751, Hyde Road, Gorton, Manchester, in the
County of Lancaster, Commercial Traveller, 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 improvements upon the invention for which Her
Majesty's Letters Patent hearing date the 11th Day of May 1896, Numbered 9,952.
were granted to me, the principal objects of the present invention being to facili-
tate the construction and to make the same applicable to the top rail of an
ordinary sash window, also when placed vertically to casements, doors, and French
windows and the like, opening and closing upon hinges, and for fixing panels
folding seats or shelves and the like sliding or moving vertically, horizontally, or
otherwise.
The nature of my present improvements and the manner in which the same
is to be performed or carried into practical effect will be readily understood on
reference to the drawings hereunto annexed and the following explanation thereof.
Fig. 1 on the drawing is an elevation, partly in section showing the method
of applying my said improvements to the top bar of the top sash of an ordinary
sash window.
Fig. 2 is a side elevation of the sash pulled a little way down, the pulley and
cord at the back being shewn and the other cord shewn broken. Figs. 1 and 2
are similar views of part of the lower sash of the window with the fastener
applied thereto; and Fig. 3 is an enlarged view of the fastener hereafter described.
Instead of making the sliding bolts and as shown on the drawings filed with.
the Specification of my Letters Patent above referred to I prefer for facility and
economy in manufacture to make the bolt ends solid as heretofore and to make
the shank and other portions of the same of a piece of round wire a, b, the inner
ends of which are cranked and bent into the form shown in the drawings, and
their outer ends screwed into the blocks a, b, which form the bolts. I also
make the central boss f in the form shown at Fig. 3 with a notch at top and
bottom in which the wires a and lie, and with an additional projection f*
to act as a stop and limit the amount of rocking action. I also prefer to arrange
the coiled springs so that the wires a and b pass through them.
When applying my invention to ordinary sash windows, instead of fixing the
apparatus on the top or bottom of the window frame I cut a rebate in the upper or
lower part of the inside of the sash frame. into which I .fit 'the casing flush with the
inside of the frame so that the bolt ends a, b, do not interfere with the cords.
also prefer to line the stile with thin sheet metal m (Figs. 1 and 1) such as
zinc or brass to prevent wear and to make the sash run easily.
I
Instead of the handle or knob g I attach to the inner end of the spindle of the
boss f. in the case of a top sash a short lever which hangs down at an angle
when the bolts a and b are shot as shown at Fig. 1. and to this lever I attach

page_text: (by a ring or otherwise) a cord i, and I make the sash weights & heavier than the
top sash so that their tendency is to lift the sash, and to keep it always at the
top, and when so raised the spring bolts a and b will secure it in that position.
When it is required to lower the sash, the cord & must be pulled straight down,
the first effect of which will be to draw down the lever into a perpendicular
position causing the central boss † to rock and release the bolts a and b, and as
the downward pull on the coru i is continued it will pull the sash d down, and on
releasing the cord the spring bolts a and ₺ will fix it and bring the short lever *
again into the diagonal position.
To raise the sash all that is required is to pull the short lever back into
the perpendicular position by the cord & so as to withdraw the bolts a and b and
to hold it in that position as the falling of the sash weights & raises the sash d
up again to the top. On releasing the cord 7.the spring bolts a and b will shout
out and fix the same.
The method of applying my invention to the other analogous purposes herein-
before mentioned is too obvious to require any further explanation.
The mechanism of the fastening will in all cases be practically the same, the
only differences being that the fastenings must be fixed either horizontally
vertically or otherwise, and, that the bolt ends must be bevilled rounded or left
square according to circumstances.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed L declare that what
I claim is:-
1. The construction and application of the improved fastening for railway
carriage and other windows sliding panels and the like substantially as herein-
before described and illustrated by the drawings annexed.
2. The improved arrangement of fastening applied to sash windows, substan-
tially as hereinbefore described and illustrated by the drawings annexed.
