PROVISIONAL SPECIFICATION.
Improvements in the Moveable Windows of Vehicles.
STANLEY BETJEMANN of 21 Agate Road The Grove Hammersmith Mechanician do
hereby declare the nature of this invention to be as follows:-
The object of my invention is to improve the moveable windows of vehicles—such
as carriages, cabs omnibusses, tram cars, railway carriages &c. To achieve this I
construct the frames of the windows of metalic tubes, having a slit in one side to
receive the edge of the glass, joining the angles of the frame in any convenient way,
but I prefer to use a clamp in two parts-divided on the plane of the glass, and fitted
to receive the ends of the tubes at the required angle, and held together with the
tube ends and glass between in any suitable way-The frame can then be taken to
pieces for the renewal of the glass when broken. The tubes may be flattened to an
oval section if desired.
A second part of my invention is improved methods of working the front windows
of hansom cubs one method is to hingo, or pivot the frames vertically, at either side
of the cab, and fold them back from the centre, against the side windows, like the
leaves of a screen.
Another method is to divide them horizontally in the usual manner, but instead of
hinging the top frame to the cross piece under the roof, I hang a lever like piece, at
either end to the same line. The top frame is pivoted at the ends, at any convenient
point to these hanging pieces, when the windows are down, the top frame can be tilted
inwards for ventilation. When the windows are being raised, the lower frame sliding
up behind it, will force it back to its forward position, and the two frames will fold up
against the roof, in the usual way, or may turn on the pivot, so that the top edges of
the frames, will project into the cab, in the action of being drawn up to the roof.

COMPLETE SPECIFICATION.
Improvements in the Moveable Windows of Vehicles.
I, STANLEY BETJEMANN of 21 Agate Road The Grove Hammersmith, Mechanician
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 :-
The object of this invention is to improve the moveable windows of passenger
vehicles, especially hansom cabs, by making them of metal tubes, of a suitable 'form
with a slit or groove in it to receive the glass. By this means a much improved
appearance is obtained and less light is obscured than by the ordinary wooden frames.
For the purpose above described 1 employ metal tubing of the required section,
drawn in the usual method, leaving an opening, or slit, along one side to hold the
odge of the glass.
The angles or mitres are held by pieces of metal fitting inside the tube, at the
corners of the frames and screwed or rivetted from the outside.
To stiffen the tubes I have pieces of wood, the shape of the inside of the tube,
forced into them, to meet the angle pieces at the corners, the pieces of wood are
grooved to correspond with the groove or slit in the tube, to receive the glass.
A second part of my invention is the placing of a fixed eye or pulley on the side
or slide of the upper frame of a hansom cab front window, for the lifting cord or
strap to pass through.

page_text: The object of this is to get a direct lift when the window is turned up against the
roof, and so avoid strain.
The frames to which this improvement is applicable, are the ordinary ones in
common use, in which the upper frame is hinged at the upper horizontal edge to the
under side of the front of the roof of the cab so that it may fold up under the roof.
On the side edges of this upper frame are screwed strips of metal to form a slide,
into which the lower frame (which is about the same size as the upper one) telescopes
upwards till the lower one lies on the upper one, when the two are folded up under
the roof by means of a strap or cord attached to the lower frame which passes over a
pulley in the roof to the drivers hand.
To get the lower frame to slide up, the roof pulley must be placed in so forward a
position, that when the frames are folded up the hitching point on the lower frame is
several inches behind the pulley, consequently the strap or cord is pulling forward at
a strong tangent, involving great strain.
By my improvement, the strap or cord instead of going direct to the roof pulley
passes through an eye or pulley on the slide of the upper frame several inches from
the bottom edge, and thence to the roof pulley, which is placed farther back at the
exact point to get a direct lift as the frames fold upward.
The eye on the slide causes the cord to pull in a direct line on the lower framo and
telescopes it to its proper position before it begins to fold up. This will be clearly
understood by reference to the accompanying drawings Figs. 3. & 4.
Fig. 1. is a cross section of the frame.
Fig. 2. is a longitudinal section of the same.
A. is the tube. B. is the wood lining. C. is the angle piece. D. is the groove in
the wood for the glass. E. is the glass. F. F. F. are screws that hold the angle
piece and the tube together.
Fig. 3. is a side view of the frames in their place, the window being down.
Fig. 4. is the same with the window up. These two Figs. are to show the second
part of my invention.
A. is the top frame with the lifting pulley at B. C. is the lower frame with the
cord attached at D. E. is the pulley in the roof over which the cords or straps run.
A cord from each side and passing over a centre pulley would be used with these
frames.
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 construction of the moveable windows for passenger vehicles from metalic
tubes practically as described.
2. The placing a fixed eye or pulley on the upper frame of a hansom cab window,
as, and for the purpose described.
