PROVISIONAL SPECIFICATION.
New Method of Raising, Lowering and Holding Window Sashes.
THOMAS CROOKE 5 Hilldrop Crescent. N. in the County of Middlesex, Coal
Merchant JOSEPH. THOMAS. NICHOLLS 49 Ellington Street Barnsbury Engineer in
the County of Middlesex do hereby declare the nature of this invention to be us
follows:-
A vertical rod of any required length is fastened to the middle of the bottom of
the window sash, projecting downward, at the lower end of the vertical rod is a
hole.
On either side secured to about the middle of one of the pillars of the well is a.
plate with vertical joint flange in centre.
A long arm is jointed at one end to the vertica Iflange on the plate revolving
vertically up and down across the well, a stud hole is placed near the opposite end of
the long arm.
A connecting rod with a stud hole at each end is jointed at one end to the hole
near the travelling end of the long arm acting obliquely upward, An angle lever
with joint at the angle, acts on a horizontal bolt fixed in the garnish rail about the
centre. The lower end of the angle lever is jointed to the upper end of the con-
necting rod.
At the upper end of the top leg of the angle lever a handle projecting upward
above the garnish rail is attached to it by a stop joint, By moving the Handle
sideways the travelling end of the long arm is raised or lowered.
A sheave pulley running vertically is fixed near the end of the garnish rail.
Attached to the lower end of the vertical rod is one end of a chain, band or cord
made of any substance suitable. The said chain or band runs over the pulley and is
fastened to the other end in the hole in the extremity of the long arm.
When the sash to which the "New Method" is applied is very heavy a balance
weight is attached to the travelling end of the long arm a spring is employed for
the same purpose, or both.
In the handle a pawl piece is placed with small spring attached.
Fixed to the garnish rail is a ratchet piece for the pawl piece to catch in.
The lower end of the handle is produced and formed so as to lift the pawl piece
out of the ratchet, and release the handle. By this arrangement the window sash is
placed and held at any required height.
To prevent water entering the well and injuring the several mechanical part of the
"New Method of Holding Window Sashes," a water guide is placed on the fence rail
of the window composed of a piece of angle sheet metal fixed along the bottom of
the window sash.
A long piece of sheet-metal (S shaped) runs parallel to the angle piece and is hinged
on the fence rail of the window, one part of the angle shaped piece turns over the fence
rail and the other part of the S shaped piece goes under the angle shaped piece when
the window is up, being so placed by a projection at the bottom of the window sash

page_text: catching on two small levers which are jointed to the pillars of the well and the S
shaped piece, when the window is lowered, the position of the S shaped piece is
reversed.

New Method of Raising, Lowering, and Holding Window Sashes.
We THOMAS CROOKE (Gentleman) 5 Hilldrop Crescent, Camden Road. N. in the
County of Middlesex, and JOSEPH THOMAS NICHOLLS (Engineer) 49 Ellington Street,
Barnsbury N. 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 suitable 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, with front
outer panel removed.
(A 2.) Movable window sash.
(B. 2) Outside frame of carriage door.
(C. 2) Pocket or well in which the window sash is placed.
À vertical rod A (Fig. 17.) of any required length is fastened to the middle of the
bottom of the window sash projecting downwards. At the lower end of the vertical
rod A, is a hole, (shown in detail Fig. 17.). On either side, secured to about the
middle of one of the pillars of the well is plate B, with vertical joint flange in
centre. (Figs. 5, 5, 5".) A long arm C (Fig. 6) is jointed at one end of the vertical
Hange on the plate B (Fig. 5) revolving vertically up and down across the well
(Fig: 1 C. 2). A stud hole is placed near the opposite end of the long arm C. (Fig 6.)
A connecting rod D. (Fig. 7) with a stud hole at each end, is jointed at one end to
the hole near the travelling end of the long arm C. (Fig 6) acting obliquely upwards.
An angle lever E. (Fig 8) with joint at the angle, acts on a horizontal bolt fixed in
the garnish rail about the centre. The lower end of the angle lever E (Fig 8) is
jointed to the upper end of the connecting rod D. (Fig 7.) At the upper end of the
top leg of the angle lever E. (Fig. 8) a handle F. (Figs 9, 94) projecting upwards
above the garnish rail is attached to it by a stop joint. By moving the handle F.
(Figs. 9, 9) sideways, the travelling end of the long arm C. (Fig 6) is raised or
lowered.
A sheave pulley G. (Fig 10) running vertically is fixed near the end of the garnish
rail. Attached to the lower end of the vertical rod A, (Fig 17.) is one end of a
chain, band, or cord, made of any substance suitable. The said chain or band (A¹
Fig 11) runs over the pulley G. (Fig 10.), and is fastened. to the other end in the
hole in the extremity of the long arm C. (Fig 6). When the sash to which the new
method is applied is very heavy, a balance weight C (Fig 12) is attached to the
travelling end of the long arm C (Fig 6). A spring B. (Fig 13.) is employed for
the same purpose or both. In the handle F. (Figs 9, 9A) a pawl piece M. (Fig 14)

page_text: is placed, with small spring attached, M¹ (Fig 15). Fixed to the garnish rail is a
ratchet piece L (Fig. 16.), for the pawl piece to catch in. The lower end of the
handle F. (Figs 9, 94,) is produced and formed, so as to lift the pawl piece (M. Fig 14)
out of the ratchet L. (Fig 16); and release the handle F. (Figs 9, 94,) is produced
and formed, so as to lift the pawl piece (M. Fig 14) out of the ratchet L. (Fig 16);
and release the handle F. (Figs 9; 9). By this arrangement, the window sash
(Fig. A) is placed, and held at any required height. To prevent water entering the
well (C 2 Fig 1), and injuring the several mechanical parts of the new method of
holding window sashes, a water guide is placed on the fence rail N (Figs. 29, 26, 27
& 28) of the window. Composed of a piece of angle sheet metal H
(Figs. 18, 19, 27, 28) fixed along the bottom of the window sash A2 (Fig 1). A long
piece of sheet metal I. (Figs 20, 21, 26, 27, 28) runs parallel to the angle piece H
(Figs. 18, 19, 27, 28), and is hinged on the fence rail of the window. One part of
the S-shaped piece 1. (Figs 20, 21, 26, 27, 28) turns over the fence rail N
(Figs 29, 26, 27, 28), and the other part of the S-shaped piece I (Figs. 20, 21 26, 27, 28)
goes under the angle shaped piece H (Figs. 18, 19, 27, & 28). When the window
is up, being so placed by a projection J (Figs, 24 25, 27, 28) at the bottom of the
window sash, A2, (Fig 1) catching on two small levers J and K, (Figs. 22, 23, 26,
27, 28) which are jointed to the pillars of the well, and the S-shaped piece, I.
(Figs, 20, 21, 26, 27, 28). When the window is lowered, the position of the S-shaped
piece I, (Figs 20 21, 26, 27, 28) is reversed.
When the sash holder is applied, and in use, the window sash A2 (Fig 1) is kept
up any required distance by means of the Pawl piece M (Fig. 14) acting on the
ratchet L. (Fig 16). By pulling the handle F. (Figs 9, 94) sideways, the pawl piece
M. (Fig 14.) is released from the ratchet 1. (Fig. 16) allowing the window sash
(A2 (Fig. 1) to be raised or lowered.

window sash down or open.

Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is performed, we declare that what we
claim is:-
(Firstly) The levers as applied.
(Secondly) The balance weight as applied.
(Thirdly) The Handle, Crank lever, Ratchet and Pawl piece as applied.
(Fourthly) Chain and Pulley as applied, and shown on the drawings.
