COMPLETE SPECIFICATION.
Improvement for Raising and Lowering Railway Carriage and other
Windows.
ALLEN BELL, 242, Brookhill, Sheffield, Yorks., "Manager," JOHN PIEL HAIGH,
95, Weigh Lane, Sheffield, aforesaid, "Clock Maker," 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 relates to improvements in appliances for raising railway
carriage windows and other like windows or sashes, and for retaining them when
lowered to any point, also for releasing them when desired.
It is illustrated in the sheet of drawings annexed, in which like letters of refer-
ence indicate like parts in each of the several figures.
Fig. 1, represents a railway carriage door in elevation, with the front casing
removed to show the window or glass frame and the lifting appliance.
Fig. 2, is a similar elevation of a door with the front casing in position.
Fig. 3, represents a portion of the rack and the spring catch, on an enlarged
scale.

page_text: Fig. 4, shows the winding barrel with its spring and part of the lifting strap,
on an enlarged scale.
The door frame is marked 6, the front casing H, and the window or glass
frame I.
In carrying out our invention as shown in the drawings we provide two wind-
ing barrels B, preferably pivotted upon plates A, and fitted with internal coiled
springs C, and we fix them to the door frame G, in a suitable position for the
purpose for which they are required, such as that shown in Fig. 1.
To the outside of each barrel B, we attach one end of a strap, chain, metallic
tape or the like J, and the lower end of such strap or its equivalent we secure
to the side or edge of the glass frame or window I.
The winding barrels and the lifting attachment are adjusted to lift the window
to its highest position.
To one side of the glass frame I, we fix a rack D, and to the door frame we fix
a spring catch F, arranged to engage with the teeth of the rack. and thus to
retain the window or glass frame at any height, it is provided with a button E,
projecting through the door casing H.
When the window is pressed down by hand the barrels are caused to revolve
and thereby to coil up the springs, and when the knob or button E, is pressed
inwards the catch is withdrawn from the rack, the window released and is imme-
diately raised by the action of the spring barrels B.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is: -
1. The arrangement of the combined mechanism for raising and lowering
windows or sashes as hereinbefore described and set forth.
2. An arrangement of mechanism for raising holding and releasing the win-
dows or sashes of railway carriages and other like sashes consisting of two spring
winding barrels B, provided with lifting straps J or equivalents, a rack 1), and
co-acting catch F, for retaining and releasing, as hereinbefcre described and
shown.
