PROVISIONAL SPECIFICATION.
Improvements in Window Sash Holders for Railway Carriages and
other Vehicles.
I, GEORGE INGRAM, of 4A Chapel Street, Marylebone in the County of
Middlesex, Clerk, do hereby declare the nature of this invention to be as
follows:-
I place horizontally across the top of the window-sash frame a metal rod having
a double cam and a central pivot at each end and a knob or finger-piece at the
middle. I fasten to each side of the said frame, vertically, a flat spring, one end
of each spring being turned over so as to form a round hole for the said pivots
to enter and partly rotate in, I screw to each side of the sash frame a small metal
plate as a fulcrum behind each cam, and adjacent to these fulcra-plates I screw,
not quite home, plates made angular, so as to jut over the wood, or wood strips
forming the guides for the window sash on each side of the carriage door. The
springs pass against the said angular plates, whose grip on the said wood or wood
strip holds the window in position, pressure applied, either upwards or downwards
to the knot or finger-piece takes the pressure of the springs off the angle plates, the
pressure being resumed after the window is raised or lowered to the desired
position.

COMPLETE SPECIFICATION.
Improvements in Window Sash Holders for Railway Carriages and
other Vehicles.
I, GEORGE INGRAM, of 4A Chapel Street, Edgware Road, in the County of
London, Clerk, 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 :-
My invention relates to improvements in window sash-holders for railway
carriages and other vehicles.
I place horizontally across the top of the window sash frame a metal rod having
a double cam and a central pivot at each end, and a knob or finger piece at the
middle.
1 fasten to each side of the said frame vertically a flat spring, one end of each
spring being turned over so as to form a round hole for the said pivots to enter
and partly rotate in. I screw to each side of the sash frame a small metal plate
as a fulcrum behind each cam and adjacent to these fulcrum-plates I screw, not
quite home, plates made angular, so as to jut over the wood or wood strips form-
ing the guides for the window-sash on each side of the carriage door.
springs press against the said angular plates, whose grip on the said wood or wood
strips holds the window in position. Pressure applied, either upwards or downwards,
to the knob or finger-piece, takes the pressure of the springs off the angle plates,
the pressure being resumed after the window is raised or lowered to the desired
position.
The
I attain this object by the mechanism illustrated in the accompanying drawings,
in which-

page_text: Fig. 4 is a view of the inside of the swell on the top of the spring.
Fig. 5 is a view of the hold fast or fulcrum-plate.
Fig. 6 is a view of Fig. 4 with the cam on the rod passing into its position.
Fig. 7 is an alternate view of the inside of the swell on the top of the spring.
Fig. 8 is an alternate view of a holdfast or fulcrum plate.
Fig. 9 is a view of Fig. 8 on the opposite side.
Fig. 10 is a view of the grip and pin.
Figs. 11, and 15, are alternate cains at the ends of the rod.
Fig. 12 is a view of the hold fast for the centre of the rod.
Fig. 13 is a view of the lift in the centre of the rod.
Fig. 14 is a view of a plate to be placed at the bottom of the window frame.
Fig. 16 is the rod with a cast lift in elevation.
Fig. 17 is a plan of the cast lift.
Several of the figs. are broken off for want of space.
Like letters refer to like parts throughout the several views.
In Fig. 1 I make the angle plates so that the central pivots on the angle
plates and on the transverse rod d shall enter into the heads of springs g, the
said angle plates facting swivel-like on the said pivots, (which pivots, with the
springs 9 described, fitted into the angle plates hinge-like,) support the angle-
plates and sash h.
The action of the cams d" on the transverse rod d when pressure is applied
to the finger-piece or lift c to press the said cams d" against plates and thereby
taking the pressure of the springs g off at the swell or head which lifts the grip
plate away from the door frame a while the sash his being raised or lowered
by the fingers of the operator. The screws at the head of the springs g are
not screwed home but left out to allow, sufficient play for the heads of springs
to work.
In Fig. 2 is represented the swivel-like action in two slide blocks e whose
pivots e are fitted into a hole in the swell or heads ; of the springs y as
described in Figs. 4, 6, and 10. The fulcrum or holdfast is screwed to the
sash and the rod d with the cams are fitted to the heads j of the spring g
and passed upwards through the slot in the plate i Fig. 5 into position, the aforesaid
arrangement being secured by a bearing plate 6 Fig. 12 screwed over the centre of
the rod d between the loop c¹ beneath the lift c.
b
In Fig. 3 the pivots of the trausverse rod d are fitted into two stays f¹ Fig. 8,
the cams d' in this case acting against the head; Figs. 7, and 9, of the springs g.
The hole in the spring head; being made to receive the pivot e¹ of Fig. 10, the
slide e is then held in a rigid position by means of the springs g after they are
screwed to the sash h.
The various plates f, f, and i, and the heads j of the springs are of both right
-and left hand.
The fingers of the operator applying pressure to the finger-piece or lift c at the
centre of the transverse rod d presses the cams d' against the plates for i and the
heads of the springs g and so releases the grip of the angle plates for the slides e
on the said door frame a. Wood, metal or composition strips if preferred may be
fixed to door frame a for the purpose of providing a better grip or hold. After
the sash is put to the desired position it will stop by the aid of my hereinbefore
described invention.
The finger piece or lift is made in the form of a loop c¹ on the transverse rod d
but if preferable any other shaped lift may be adopted as in Figs. 16 and 17.
At the bottom of the sash h, in the middle, I screw a plate Fig. 14 so as its top
edge shall be above the wood of the bottom rail of the sash frame and opposite the
glass of the sash h, in order that the fingers of the operator may enter the available
space between the glass and the said plate to pull the sash from over the fence
rail of the carriage door, where it is sometimes placed in wet weather or during
the washing of the vehicles.
The central stay or plate 6 of the transverse rod d is made to go over the rod

page_text: in the loop c¹ made thereon for the finger piece or lift e; or a solid lift 1 with a
slot 2 to receive a clip 3 on a cast stay bas in Figs. 16, and 17, may be adopted
if preferred.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a window sash-holder for railway carriages or other vehicles, the combina-
tion of the springs 9 cams d" angle plates f transverse rod d loop c¹ lift c and stay b,.
substantially as herein described and according to Fig. 1 of the accompanying
drawings.
2. In a window sash-holder for railway carriages or other vehicles, the combina--
tion of the slides e pins & heads ; springs g plates i cams d rod d loop and lift c
and stay b, substantially as herein described and according to Figs. 2,4,5, 6, 10, 11, 12,
and 13, of the accompanying drawings.
3. In a window sash-holder for railway carriages or other vehicles, the combina-
tion of the slides e pins e' heads j springs 9 plates f cams d' rod d loop c¹ lift c and

and 15, of the accompanying drawings.
4. In a lift for a window sash holder, the combination of a plate 1 a slot 2 and
plate 6 with a clip 3, substantially as herein described and according to Figs. 16.
and 17, of the accompanying drawings.
