I, HENRY WALTER BROWN, of Walham Green, in the County of Middlesex,
Gentleman, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN WINDOW FRAMES, AND IN GLAZING WINDOWS," to be as follows:-
My object is to render windows, and especially the windows of railway
carriages, cabs, and other vehicles noiseless at all times, and when closed dust
and water tight.
For this purpose I construct the window frames as follows:-Where the
outside edge of my sash is intended to slide, as in the case of the stiles of an
ordinary sash window, I form a groove along the outside edge. These grooves
fit upon and slide along a beading of vulcanized india-rubber or other suitable
fabric, which beading is fixed into the corresponding inner surface of the stile
of the window frame. Where there is much friction between the groove and
the beading I sometimes line the grooves with pewter or other suitable metal.
Where the window shuts upon or against the window frame, as in the case of
a common sash window, I form a similar groove along the edge or the face of
the rail or stile which shuts upon or against a corresponding beading fixed
along the frame, upon or against which the window shuts.
The second part of my Invention consists in the mode in which I some-
times fix my beading of elastic material, and this I do as follows:-I first
form in the wood which has to carry the beading a groove of a size and shape
suitable to receive the beading. This groove, where expense is of small

page_text: importance, may be lined with metal, I then stretch the beading longitudinally
until I have sufficiently diminished its diameter to enable me to slip it easily
into the groove. After placing it in the groove I remove its longitudinal
stress, upon which it resumes at once its normal shape, and fits tightly and
accurately into the groove without any application of glue or other adhesive
material. These elastic beadings may, however, be placed and sustained in
their grooves in any ordinary way.
A third part of my Invention consists in the mode applied by me to fix
carriage windows when pulled up either fully or partially. I fix in a suitable
part of the framework of the window the following contrivance :-I take a
blunt pointed stud of a suitable length, the shaft of the stud, which must
not be round, I form into a female screw, into which I cause a male screw to
work. This male screw also passes through a socket in the framework of the
window and terminates by a convenient head or handle inside the carriage.
The stud is arranged to move freely backwards and forwards. When I want
to fix the window I turn the handle or bead of the screw so as to make the
point of the stud travel forwards until it gently presses against the framework
of the sash so as to hold it in its place. A travelling stud of this description
may be applied to either side of the frame of the window, or placed so as to
work against the bottom rail of the window, and such stud may be made with
a single head or with more than one.
The fourth part of my Invention is the mode adopted by me for glazing
carriage and other windows. If the glass has any cutting edges they must be
smoothed by grinding or other suitable means. I stretch all round the glass
over its edges a folded elastic band of vulcanized india-rubber or other suitable
material. This band when fixed is nipped between the sash framing and the
metallic or other framing hereafter described. I then place the glass into
its sash frame, and fix it there by placing upon its edges a metallic or other
suitable framing or beading, which I retain in its place by screws or other
suitable means.
