I, CHARLES GROOMBRIDGE, of Edmonton, in the County of Middlesex, Gentleman,
do hereby declare the nature of said invention for IMPROVEMENTS IN MEANS
OR APPARATUS FOR RAISING AND CLOSING WINDOWS, SASHES, PANELS AND
SHUTTERS OF ALL KINDS, MORE PARTICULARLY APPLICABLE TO THE WINDOWS
OF RAILWAY AND OTHER CARRIAGES, to be as follows:-
+
My Invention relates to improvements in means or apparatus for raising and
closing windows, sashes, panels and shutters of all kinds, and is more particularly
applicable to the windows of railway and other carriages, and which, by way of
example, I proceed to describe.
In carrying out my Invention I fix to the lower bar or rail of the window a
block carrying a spring pawl or click which enters the teeth of a vertical rack
pivotted at its lower end to a cross bar secured in the casing of the door. To this
cross bar is also pivotted the lower end of a lazy-tongs arrangement, whose upper
end is secured to the aforesaid block. The lowermost pair of levers of the lazy-
tongs arrangement is attached to springs which actuate the same to raise the
window on the rack being displaced. To the uppermost end of the rack is secured
a knob or handle by moving which horizontally this rack is released from the pawl
or click, thus allowing the lazy-tongs to come into action and to raise the window.
On the knob or haudle being released a spring restores the rack to its vertical
position and brings its teeth again into contact with the pawl or click. By
releasing the knob or handle at any point the window is arrested or stopped at
any desired height. The window may be lowered to any point by applying
downward pressure to a finger-plate attached to its upper bar or rail.
In order to raise the window from the outside of the carriage, without the
necessity of opening the door for the purpose, I provide on the outside of the door
a knob or handle whose spindle slides in a horizontal slot in the casing of the door
and actuates a system of levers in connection with the vertical rack and releases
it from the pawl or click in the same manner as does the knob or handle on the
inside of the door., . This outside handle is restored to position by the said system
of levers. The lowering of the window from the outside is effected in like manner
as from the inside by downward pressure on a finger-plate on the upper bar or
rail.

AND
I, CHARLES GROOMBRIDGE, of Edmonton, in the County of Middlesex, Gentleman,
do hereby declare the nature of said invention for IMPROVEMENTS IN MEANS
APPARATUS FOR RAISING AND CLOSING WINDOWS, SASHES, PANELS
SHUTTERS OF ALL KINDS, MORE PARTICULARLY APPLICABLE TO THE WINDOWS
OF RAILWAY AND OTHER CARRIAGES, and in what manner the same is to be i
performed, to be particularly described and ascertained in and by the following
statement, reference being had to the accompanying drawings, and to the letters
and figures marked, thereon, that is to say:
My Invention relates to improvements in means or apparatus for raising and
closing windows, sashes, panels and shutters of all kinds, and is more particularly
applicable to the windows of railway and other carriages or vehicles.
By way of example I proceed to describe my Invention as applied to the window.
of a railway or other carriage, reference being had to the accompanying drawings
in which
Fig. 1 is a front elevation of the inner side of a door of a vehicle shewing its
'window raised and closed.
Fig. 2, a similar view shewing the window lowered.
Fig. 3, a side elevation, and
Fig. 4 a front elevation of the outside of the door.
In figs. 1 and 2 the inner panel of the door is removed in order to shew clearly
the means or apparatus for raising the window.
.
In carrying out my Invention, I fix to the lower bar or rail A of the window
a plate or block a, carrying a spring pawl or click b, which enters the teeth of a
vertical rack B. This rack is pivotted, at its lower end, at c; to the cross bar D,
which is secured in the casing of the door. To this cross bar D, is also pivotted
the lower end of a lazy tongs arrangement E, whose upper end is pivotted to the
aforesaid plate or. block a. The lowermost pair of levers of this lazy tongs
arrangement is attached to spiral springs G, G, which actuate the same to raise the
window, on the rack B being displaced. To the uppermost end of this rack. is
secured a knob or handle H whose spindle passes through a slot / cut in the cross
framing Z of the door, and by moving this knob horizontally, the rack is released
from the pawl or click b, thus allowing the spiral springs G G to contract, as shewn
in fig. 1, and the lazy tongs arrangement to come into action and raise-the window.
On the knob or handle H being released a spiral spring J, having one of its ends
secured to the rack and the other to the stile of the door, restores the rack to its
vertical position. and brings its teeth again into contact with the pawl or click,
By releasing the knob or handle H at any point, the window is arrested or stopped
at any desired height.
Fig. 5 shews in detached view, on a larger scale, the arrangement of spring pawl
or click in gear with the rack.

page_text: The window may be lowered to any point, by applying downward pressure to
& finger plate L, attached to its upper bar or rail.
In order to raise the window from the outside of the carriage, without the.
necessity of opening the door for the purpose, I provide, on the outside of the door,
a knob or handle H* whose spindle f is secured to a sliding bar m, working in
guides mx, so as to steady the motion of the handle. At its inner extremity, this
spindle is connected to one end of a bar n, which is jointed at its other end to a
vertical lever N. This lever N is pivotted at its uppermost end to the cross bar Z
and lies parallel with the rack B. O is a cross bar connecting the lever N with
the rack B. On the handle H* being moved, movement is communicated by its
spindle to the bar n which actuates the vertical lever N which in its turn, through
the medium of the cross bar O, displaces the rack, thereby freeing its teeth from
the pawl and permitting the window to rise. On the handle being released it is
restored to position by the bar. n and lever N.
The lowering of the window from the outside, is effected in like manner, as from
the inside, that is to say, by downward pressure on a finger plate L* fixed to the
upper bar or rail of the window. The window slides in a guide or groove s.
For raising heavy windows, shutters, panels or sashes two or more sets of the
apparatus or mechanism herein described may be used in combination.
Although I have described and shewn my invention as applied to the raising
and closing of the window of a vehicle, wholly or partially, it can be applied, in
like manner,
to the raising and closing of sashes, panels and shutters, and the
means for operating the mechanism from the outside may be dispensed with, if not
necessary, in any of these instances.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. The general arrangement and combination of the parts constituting the means
or apparatus for raising and closing windows, sashes, panels and shutters, sub-
stantially as herein described and as shewn in the drawings.
2. In combination with the window of a vehicle, the lazy tongs arrangement E,
operated by its springs G, G, the rack B actuated by the knob or handle H, tho
spring J, for restoring the rack to its normal position, and the spring pawl or
click b, in gear with said rack, all combined to operate substantially as described,
and as shewn with reference to.figs. 1 and 2 of the drawings and for the purposes
set forth.
3. In combination with the means or apparatus above claimed, the arrangement of
the sliding bar m, vertical lever N, and connecting rod O, actuated by a knob or
handle, on the outside of the door, for the purpose of raising and closing the
window, without opening the door.
4. The combination with sashes, panels and shutters, of the means, or apparatus
herein described, whether the same be used singly or in two or more sets in
combination, substantially as and for the purpose set forth.
