I, JAMES GORDON, of 161 Varna Road, Edgbaston, Birmingham, County of
Warwick, Coach Builder, do hereby declare the nature of this invention to be
as follows:-
This invention relates to the improvements hereinafter described in window
sashes and has for its object to provide means whereby such sashes may be
raised and lowered as desired in a simple effective manner. When applied to a
cab my invention consists essentially in providing the sides of the window sash
with anti-friction rollers working in grooves formed in a frame attached to the
roof of a cab in such a manner whereby the rollers follow the path of the grooves
thus enabling the raising and lowering of the said sash.
In carrying my invention into practice I make a frame of steel, iron, or
other metal, or of wood, having bifurated fork like ends one of which depends
vertically from the end of the fork, the other fork terminating into a semi-
circular recess. The said frame is arranged to be attached to or to form part of
the roof, that is to say the extended part of the frame is attached to the extreme
edge of the roof and side of the cab with fork like end projecting diagonally,
close to the side thereof, thus forming a ] shaped groove or channel which
shoots off at a junction some little distance from the end thereof, the horizontal
end of the said channel forming one part of the fork terminates into a semi-
circular recess, that is to say the end projects a little below its centre forming a
lock for the roller and sash. I furnish the window frames on both sides with
two or more anti-friction metal rollers covered with rubber or they may be made
entirely of rubber or the like. The said rollers engage in and are capable of
rotating in the said channel taking the path thereof. I make the window frame
of L shaped sheet steel or other sheet metal, the glass fitting up or lying against
the long flat side of the angle and is held in position by a wood fillet pressing
against the glass on one side and on the other against the short turned up part
or lip of the angle which I make taper so as to effect tightening up of the same,
thus facilitating the changing of broken glass. When the sash is in place in a
closed position the top roller aforesaid rests in the lock aforesaid. The sash is
raised either by a cord or strap, raising the top roller out of the lock which
slipping along the channel along the cab roof the bottom rollers following the
vertical and diagonal path and hence to the horizontal path. When it is desired
to open the window a little at the top the sash is pulled or lifted up which
brings the top roller along the horizontal path of the channel thus lowering the
position of the rollers, hence the sash to its open position. By a slight modification

houses, or other buildings.

Improvements in or relating to the Raising and Lowering of
Window Sashes of Cabs and other Vehicles, also applicable to
other Windows.
I, JAMES GORDON, of No. 161, Varna Road, Edgbaston, Birmingham, in the
County of Warwick, Coach Builder, 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 the improvements hereinafter described in window
sashes and has for its object to provide means whereby such sashes may be
raised and lowered as desired in a simple effective manner. When applied to a
cab my invention consists essentially in providing the sides of the window sash
with anti-friction rollers working in a grooved frame attached to the cab roof
in such a manner that the rollers follow the path of the grooves thus allowing
the raising and lowering of the said sash.
In carrying my invention into practice I make a frame of steel, iron, or other
metal or of wood having bifurated fork ends one of which depends vertically
from the end of the fork the other fork terminating in a semicircular recess.
The said frame is arranged to be attached to, or form part of the cab roof,
that is to say the extended part of the frame is attached to the extreme edge of
the roof and side, with the fork ends projecting diagonally close to the side of
the cab, thus forming a ☐ shaped groove or channel which shoots off at a junction
some little distance from the end thereof. The horizontal end of the said channel
forming one part of the fork terminates in a semicircular recess that is to say
the end projects a little below its centre forming a lock for the roller to catch.
I furnish the window frame on both sides with two or more anti-friction metal
rollers covered with rubber, or made entirely of rubber or the like. The said
rollers engage, and are capable of rotating, in the said channel taking the path
thereof. I make the window frame of L shaped sheet steel or other sheet metal
the glass fitting up or lying against the long flat side of the angle and held in
position by a wood fillet pressing against the glass on one side and on the
other against the short turned up part or lip of the angle which is made taper
to effect the tightening up, thus facilitating the changing of broken glass. When
the sash is in place in a closed position the top roller aforesaid rest in
the lock part aforesaid of the channel. The sash is raised by a cord or
strap raising the top roller out of the lock which slips along the cab roof the
bottom roller following the vertical and diagonal path and hence to the horizontal
path. When desired to open the window at the top the sash is pulled or lifted
up which brings the top roller along the horizontal part of the channel thus
lowering the position of the rollers, hence the sash to its open position. By a
slight modification my invention may be applied to the sashes of any windows
of greenhouses, dwelling houses, and other buildings. The nature of my inven-
tion will be more clearly understood from the accompanying drawings the same
letters of reference indicating similar parts throughout.
Figs. 1 and 2 represent in end and front elevation my invention.

page_text: Figs. 3 and 4 show in end and front elevation a window sash.
Fig. 5 shows the manner in which my invention is applied to an ordinary cab.
Figs. 6 and 7 show the method of raising and lowering the sashes.
Figs. 8 and 9 are modifications.
A represents a metal frame provided with forklike end B2 which depends into
the vertical part B³ terminating in the recesses B5 the forked end B terminating
in the semicircular recess B¹. The entire frame forms a groove or channel D.
The window frame Figs. 3 and 4 is provided with corner plates E, E, furnished
with the axles F, F, carrying the rollers G, G. I, I are rubber tyres attached
to the rollers G, G. The similar rollers H, H are attached to the window frame
by the plates K, K. A frame A is attached to each side of the cab arranged
in a similar position to that shown at Fig. 5. The action of the window frame
will be understood from Figs. 6 and 7; the rollers G, G, and H, H being placed
in the grooves or channels D are capable of rotating freely therein.
The position indicated in dotted lines at 1 shows the window closed at the
front of the cab the rollers G, G, resting in the recesses B, B4, and the rollers H, H
in the part B3 of the frame A. To raise the window a little at the bottom the
sash is raised to the position shown at 2 in which the rollers G, G, are raised
from the recesses B, B, and run along the groove D to the position indicated
at 6 the bottom roller rising to the position indicated at C.
The sash may be lowered a little at the top by allowing the rollers H,H to rest
in the recesses B5 as indicated at 3 and may be raised to the cab roof as shown
at 4 the rollers taking to the path of the frame i.e., the rollers G, G, rolling
horizontally along the groove D and the rollers H, H, up the part B³ and hence
into the position indicated at d. The sash may be raised and lowered from the
inside of the cab by hand or from the outside by means of a cord. Fig. 8 shows
a section of a sash frame, L is the glass & M a metal frame having a taper part N,
the glass being held in the frame M by a fillet of wood O, kept in position by
the taper part N. in Fig. 9 is shown the manner of applying my invention to an
ordinary window sash such as in use for dwelling houses, greenhouses and the
like. A is a metal frame to take the rollers G, G attached to the window frame P',
R being a metal recess to take the rollers H, H. The sash is shown in its closed
position at g, the dotted lines indicating the open position. The opening and
closing is effected similar to the arrangement in the cab.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is;-
-
1. The improvements in the method of raising or lowering window sashes of
cabs or other vehicles consisting of the rollers G, G, and H, H attached to the
framework of the sash and arranged to rotate in the groove D of the metal
frames similar to that shown at Figs 1 and 2 substantially as described and
illustrated in the accompanying drawings.
2. The metal frames consisting of a horizontal channel terminating at one
end into a fork like end B2, the vertical part B3 and the recesses B and 135
substantially as and for the purpose set forth and illustrated at Figs. 1 and 2
of the accompanying drawings.
3. In combination with a metal frame as claimed above the window frame
provided with rollers, substantially as described and for the purpose set forth.
