PROVISIONAL SPECIFICATION.
Improvements in Sliding Windows for Railway and other
Vehicles.
I, CLARA COLLS of Beaconwood Barnt Green in the County of Worcester do
hereby declare the nature of this invention to be as follows:-
This invention refers to new or improved means applicable to the doors and
windows of railway and other carriages and vehicles and for other purposes and
whereby the window can be easily raised or lowered, and it consists in the employ-
ment of a suitably shaped semi-revolving piece of wood, metal, or other material of
suitable width laterally and which is carried by a horizontal metal or other retaining
rod or axis from side to side of the door frame.
The semi-revolving wooden or metal piece is located in the upper part of the
permanently enclosed portion of the door and is formed with an inclined horizontal
groove upon its farthest edge behind the supporting rod or axis aud somewhat of
a V shape in cross section, the front part covering the opening of the door which
receives the window when down.
The horizontal rod is as stated supported upon each side of the frame, for which
purpose the said frame is suitably hollowed out to receive a metal plate
attached thereto formed with a cup shaped recess for retaining a hall upon
the end of the rod-suitable washers may be interposed if necessary-a second
plate is then attached to the frame by screws, which pass through same and
the aforesaid inner plate the outer plate having a hole or slot therein for the rod
to pass through, it will be understood that the outer plate or plates must be passed
onto the horizontal rod (being stopped by the ball at the end) before the semi-
revolving wooden or metal piece is threaded thereon, suitable means will be
provided whereby the ball end of the rod is placed in its seating in the frame,
the other end being retained in an aperture or slot in the opposite side of the
frame.
Let it be assumed that the window is down the semi-revolving piece which it
may be stated can be suitably weighted at the front edge will have dropped auto-
matically into position parallel with the window, by now raising the latter with the
strap or other menus and pushing it slightly outwards in the vertical grooves in
the door frame the bottom of the window is received in the horizontal groove of
the wooden or metal piece so that the window is securely retained in the
groove which tilts backwards somewhat by the weight of same, by drawing the
window a little forwards the semi-revolving piece turns and allows it to easily
slip from the horizontal groove when it is free to pass down the door in the
ordinary way.
In connection with my improvements I attach to each side of the upper portion
of the vertical grooves of the door frame a metallic or other suitable holding device
so that when the window is closed up it cannot move or rattle for this purpose a
washer or pad may be suitably fixed therein.
The attachment will also prevent the window from being raised too far above
the sill of the opening whereby it might be liable to he pushed over the before-
named grooved semi-revolving piece.
By the hereindescribed method it will be seen that the window can be easily

page_text: raised or lowered without the necessity of employing both hands as in some of the
arrangements now adopted for railway carriages.

COMPLETE SPECIFICATION.
Improvements in Sliding Windows for Railway and other
Vehicles.
I CLARA COLLS of Beaconwood, Barnt Green in the County of Worcester, 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, reference being had to the drawings accompanying this specification
and to the figures and letters shewn therein :-
My invention relates to new or improved meaus applicable to the doors and
windows of railway and other carriages and vehicles, and for other analogous
purposes, and whereby the said windows can be easily raised or lowered for closing
or opening the same.
Figure 1 of the drawings represents in part sectional elevation a door with the
window closed according to my improvements.
Figure 2 represents a side section with the window lowered.
Figure 3 represents a similar section shewing the window raised.
Figures 4 and 5 are enlarged details of my improvements.
Figure 6 represents an end view of same."
Figure 7 is a plate.
My invention consists in the employment of a suitably shaped semi-revolving
strip or bar A of wood metal or other material, preferably metal, of suitable width
and length and which is carried by means of lugs A¹ or other devices by a
horizontal metal retaining rod or axis B passing through same from side to side
of the door frame C. C. This semi-revolving strip or bar A. is located in the upper
part of the permanently enclosed portion of the door (for convenience of
illustration a part of the permanently enclosed portion is shewn broken away)
said revolving strip A is formed with an inclined horizontal groove D running
along its furthest edge and parallel with same and behind the supporting rod or
axis B and is somewhat of a V shape in cross section see Fig. 6. the front part of
said strip A forming a flat surface and covering in the vertical opening of the door
within the enclosed portion which receives the window E. when down.
The
aforesaid horizontal rod B. forming the axis upon which the strip A pivots is
as stated supported on each side of the frame as at C. C. for which purpose the
said frame is suitably cut out to receive metal plates F. F. FF, the latter being
formed with a concave recess or socket G. Fig. 7. which provides a seating for
receiving and retaining a ball or enlargement G₁ upon the end of rod B. suitable
washers may be interposed if necessary, the said plates are attached to the frame
by screws the plate F having a hole or slot for the rod B to pass through, it will
be obvious that the plates F. F' must be threaded on to the horizontal rod B (being
stopped by the bali G' at the end) before the semi-revolving metal or wooden
strip is passed on.
It has been shewn that the one end of the rod B is supported by the ball
end G', in the recess or socket G in the plate F the other end of said rod is
retained in an aperture or slot in the plate F attached on the opposite side of the

page_text: frame C. The action is thus-Let it be assumed that the window is down, the semi--
revolving strip or piece A which it may be stated can be suitably weighted if
desired will have dropped by its pivoting action automatically into a vertical
position with the window see Figure 2, by now raising the window with the
strap H or by other means and pushing it slightly outwards in the vertical
grooves in the frame the bottom edge of the window which may be edged with a
strip of metal is received in the horizontal V groove in the strip A whereby said
window is securely retained therein by its weights and fits closely against the
outside permanently enclosed part and so excludes all draught or wet. To open
the window it is merely necessary to pull it a little forwards and the semi-
revolving strip A turns or pivots on its axis B. and allows the window to easily
slip from the frame D when it is free to pass down the panel of the door in the
ordinary way.
In order that the window shall not be raised too far above the sill whereby it.
might be liable to be pushed over the grooved strip A the top part of the window
frame is suitably blocked so as to allow of the window being raised just.
sufficiently high relative to the opening for the bottom bar to pass into the
groove D.
By the herein described improved method it will be clearly understood that the
window can be easily raised or lowered without the necessity of employing both.
hands as in some of the arrangements now adopted, for railway carriages or the
like, it will also be apparent that when the window is closed all draught is excluded
by the strip A completely boxing in the window aperture in the lower part of the
door.
Having now particularly described and ascertained the nature of this my
invention and in what manner the same is to be per formed I declare that what I
claim is.
Firstly. In sliding windows for railway and other carriages and vehicles and for
analogous purposes the herein described arrangements consisting of a semi-revolving
strip or bar A in connection with the horizontal rod or axis B supported by the..
side plates F. F. F1, F2, in the frame of the window all in combination and
operating as and for the purpose described and illustrated.
Secondly. In combination the metallic wooden or other strip A having a
V groove parallel with its outer edge said strip pivoting upon the axis B by
means of the lugs B' said strip being suitably weighted if required, said V groove
providing a seating for the base of the window when raised, all in combination.
with the ball ended rod or axis B, the side plates F. F. F1, F2, substantially as.
described.
