Railway Carriage and other Windows.
JAMES WALLACE of 87 St. James's Street London, Merchant and Albert Hosier
of 41 Cheapside London Civil Engineer do hereby declare the nature of this invention
to be as follows:-
*
Our Improvements relate to an Improved Apparatus for raising lowering and
holding in position Railway Carriage and other Windows." We use a longthreaded
screw to each end of which we fasten a cogwheel. A nut with a knob attached, slides
through a slot in the crossbar over the screw rotating the same and thus turning the
cogs. The cogs actuate upon serrated surfaces thus either raising or lowering the
sash-To take off the weight we employ a coil of spring so placed that on lowering
the window, it is weighted. To hold the window in position we use a flat spring,
in conjunction with the knob, falling into a slot.

We JAMES WALLACE of 87 Saint James Street in the County of Middlesex,
Merchant and ALBERT HOSTER of 41. Cheapside in the City of London, Civil
Engineer 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 :-
This Invention relates to Improvements in automatically shutting or opening
windows. Details as per following description are specially applicable for carriage
and other Windows, in which the sliding shutters should be opened or closed with
case and securely fastened in any desired position.
This Improved Apparatus is applicable to existing Windows or other sliding
shutters, as it does not necessitate any special arrangement of the usual parts thereof.
Such being the nature and object of our Invention we will now proceed to describe
the manner in which the same is to be or may be performed or carried into practical
effect and in order that such description may be properly understood we have
annexed hereunto one sheet of drawings and have marked the same with figures of
reference corresponding with those in the following explanation.
On the annexed drawings Figure 1. represents the front elevation of the apparatus,
the locking arrangement being removed.
Figure 2. is a plan of the position of shafts, guide-rods and ratched wheel for
adjusting and holding spiral spring.
Figure 3. is a sectional plan of the apparatus.
Figure 4. shows the knob or handle for moving and locking arrangement.
1 represents a window on which are screwed a toothed rack 2, 2; on each side.
These racks are carried by two cogwheels 3, 3, which are fastened to a tube 4, the
tube is bearing on a shaft 5 whose bearings are in the side plates 6, 6;-On shaft 5
is fastened a ratched wheel 7; inside tube 4 is a spiral spring 8, which is fastened
with one end to the tube and the other to the said shaft. By means of the ratched
wheel, the spring can be wound up or tightened so as to counterbalance the weight of
the window or shutter intended to be lifted 9 is a quick threaded screw and has
on each end a cogwheel 10; 10; which also gears in the toothed racks 2; 2;-
When the nut 11, is slided along, the screw will revolve and by this action through
the cogwheels gearing in the toothed racks, the window can be raised or lowered.
12 12, are guide rods for slide 13. The slide 13 consists of two tubes which are
connected together with a plate 14 on which also the nut 11 is fastened. At the
front of plate 14 the bearings 15 are fastened for the handle shaft 16. The handle
or knob 17 is fastened to shaft 16 and has two points 18 which serve for unfastening
the lock 19. The lock 19 is guided by the shaft 16 in a slotted hole and in an

page_text: opening in plate 14 and extends into the teeth of the rod 20. The lock 19 has two
pins 21 and is here unfastened by the points 18 of the handle.
To raise or lower the window the handle is taken in hand which through the
pressure pulls first the lock out of the toothed rod 20 and can then be pushed along
to either side whereby as above described the screw and cogwheels are turned and
the window raised or lowered. When the band is taken off the handle the spring 22
presses the lock into the toothed rod 20, and at the same time brings the handle
again in its straight position.
Having now particularly described and ascertained the nature and object of our said
invention and in what manner the same is to be or may be performed or carried into
practical effect we declare that what we claim is
The novel and peculiar construction and combination of parts in the apparatus
for lifting Windows or other shutters by means of a quick threaded screw and nut,
cogwheels and toothed racks, oporated by a handle with the locking arrangement
for securely holding the window or other sliding shutters in any desired position
as above described and as illustrated on the accompanying sheet of drawings and
to which combination we lay special claim as being specially suitable for their
respective purposes.
