Improved Window Sash Holder.
Joseph ThomAS NICHOLLS Ironfounder 25 Canal Road Kingsland Road
in the County of Middlesex THOMAS CROOKE, Gentleman, 5 Hilldrop Crescent
Camden Road in the County of Middlesex, do hereby declare the nature of
this invention to be as follows:-
:-
My invention is composed of a metal bar fixed vertically in the middle of one
side of the well, or open space, for the reception of the window sash. This
metal vertical bar extends from the under part of the garnish rail to the bottoin
of the side of the well to which it is fastened. In one side of the said vertical
bar are any required number of angular notches, the lower side of each notch
being horizontal and the other side oblique. An oblong or quadrilateral sided
box slides up and down on the aforesaid vertical bar. The front plane of the
sliding box is flat and has a horizontal slot in its centre.
The back plane of the sliding box is similarly formed but has a Hange pro-
jecting from each upper corner, or angle. The one on the right corner is
vertical and level with the top and side of sliding box, and extends half way
down. In the side of this vertical flange which stands at a right angle, to the
back of the sliding box is a vertical slot extending equally from the middle.
On the other (left) corner, also at the top of the back of the sliding box, another flange
projects which has a plane at right angles, extending beyond the side of the sliding
box and is parallel to the back of the sliding box. In the parallel plane of this left
flange there is a hole in the middle, in the part of the flange which is at right angle
to the back of the sliding box, an open vertical slot extends from the top half way
down. The form of one side (say right) of the sliding box is a plain oblong plane
or parallelogram the shortest sides run from front to back of the sliding box. The
other side of the sliding box which is similar to the right side, has a vertical slot
extending equally from the centre.
In the back of the sliding box there is a T shaped slot, the cross of the T is
placed vertical, the horizontal part of it running parallel with the slot in the front
of the sliding box. In the side of the box toward the front is a flange
corresponding with the right angle plane on the left flange, with hole opposite in the
middle.
In the top of the box is a slot fitting the vertical bar running parallel to the front
of the sliding box. In the bottom of the sliding box a long slot also running
parallel to the back and front of the sliding box, fitting the vertical bar only one
way. This bottom slot is larger than the vertical bar sidewards and allows the
sliding box a slight rocking motion when sliding up and down. In the inside of
the sliding box a loose metal piece placed vertically and acting horizontally, on the
metal piece are trunnions which act in the slot in the back and front Hanes of
the sliding box, this piece forms a catch for the notches in the vertical bar.
Fixed in the holes in the side flanges is a rod running across the upper part of
the sliding box, on this rod acts a wire spring keeping the lower end of the loose
catch-piece pressed on the side of the vertical bar. A lever runs through the slot
in the vertical Hauge at the back of the sliding box extending across to the flange
on the opposite corner, and catches the other end of the wire spring, which keeps
the lever constantly pressing upwards. On the lower part of the back of the

page_text: sliding box, an arm is fixed turning upwards towards the side extending to the
top of the sliding box not quite as high as the lever on the opposite side.
When the window is pressed down, the fixed arm brings the sliding box slightly
oblique and releases the catch piece from the notches in the vertical bar. At the
bottom of the window sash, a right angle piece is fixed, the right angle part coming
under the sliding box, this right angle piece, when the window is drawn up,
bring the sliding box with it. The lifting piece is fixed to the window by means of
screws.

Wo JOSEPH THOMAS NICHOLLS Irofounder 25 Canal Road Kingsland
Rond in the County of Middlesex and THOMAS CHOOKE 5 Hilldrop Crescent
Camden Road in the County of Middlesex, 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 :-
Our invention consists of a mechanical contrivance applicable to movable window
sashes or shutters of every description acting vertically.
It is for the purpose of holding open or closed to any extent required such
window sashes or shutters, it is especially adapted to railway and other carriage
doors.
The advantages of our invention are that its construction is strong and
simple, not easily injured or put out of order and can be readily applied.
The following is an explanation of the several parts and conformation of the said
invention and of the accompanying drawings.
Fig. (1) elevation of railway carriage door with sash holder applied. The front
panel of the door is partly removed.
(A) movable window sash, (13) outside frame of carriage door, (C) pocket or
well in which the window sash holder is placed. On one side of the well a
metal bar (D) is fixed vertically. The upper end of this bar (D) is fastened by
means of screws to the under side of the garnish, or middle rnil of the door, the
lower and of the bar (D) is also fastened by means of screws to the bottom rail of
the carriage door. On one side of the bar (D) are suitably formed notches of
any number required, shown in detail (Fig. 32, Fig. 33, Fig. 34 Fig. 35, Fig. 36,
Fig. 37).
A metal piece, or sliding box (d) with flanges projecting outwards on each side,
slides up and down on the bar (D), the bar (D) preses through the sliding box (d)
vertically, one side of the opening through which the bar (D) passes is vertical, the
other side of the inside of the sliding box (d) is oblique at the top of the opening,
and open outward at the lower part which allows the sliding box (d) an oblique or
rocking motion, shown (Fig. 9).
A pin () is fixed through the box (d) to catch in the notches in the bar (D)
shown in (Fig. 8).
The vertical opening or slot in one side of sliding box (d) is shown in (Fig. 14),
AT formed piece (Fig. 1, 6) is fastened to the bottom of the window sash (A),
the lower part of which is hook shaped and bent to hold the sliding box (d), an
arm (e) turning upward and extending above the level of the top of the sliding
box (7) shown in (Fig. 3) Fig. 4, Fig. 5, Fig. 7, Fig. 8, Fig. 9 and detail in
Fig. 30, and Fig. 31. The armi (e) when pressed down by the straight part of
the shaped piece gives the sliding box (d) an oblique position on the rod (D)

page_text: and releases the pin (f) from any one of the notches on the rod (D) t
action is shown (Fig. 9).
In the vertical opening (Fig. 14) in the side of the sliding box (d) acts
oblong piece (), piece (i) is flat on one side and on the other side is a vertic
channel lengthwise, piece (i) has a trunnion on each side, the position of piece
is shown. (Fig. 4) Fig. 8 Fig. 9, and in detail Fig. 28, Fig. 29.
A wire spring on bolt (4) keeps the flat side of piece (i) pressing constant
on the plain side of bar (D). The trunnions of oblong piece (i) acts in clongat
holes in the front and back of the sliding box (d).
The sash of window by this means is held at any height or place accordi
with the position of the notches in the bar (D).

When the sash holder is applied and in use the window sash is kept up an
required distance by means of the pin (f) holding in the notches on the bar (D
By pressing the window sash down the T shaped piece (b) presses on the lever (
The lever (c) keeps the window sash from touching the arm (e). When the lever (
is bent down low enough the T shaped piece comes in contact with arm (e) an

page_text: places the sliding box (d) in an oblique position removing the pin (1) out of
the notch in the bar (D), thus letting the window down to another notch in the
bar (D).
The shape of the notelies on the bar (D) allows the window sash to be drawn up
free by the handle.
When the window sash holder is applied to heavy window sashes a weight and
pully can be applied.
