page_text: LETTERS PATENT to John Dales, of New Inn, Strand, in the County of
Middlesex, Engineer, for the Invention of "IMPROVEMENTS IN FITTING
MOVABLE OR TRAVELLING FRAMES AND SURFACES."
Sealed the 31st May 1864, and dated the 2nd December 1863.
PROVISIONAL SPECIFICATION left by the said John Dales at the
Office of the Commissioners of Patents, with his Petition, on the
2nd December 1863.
I, JOHN DALES, of New Inn, Strand, in the County of Middlesex, Engineer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
FITTING MOVABLE OR TRAVELLING FRAMES AND SURFACES," to be as follows:
My Invention relates to certain improved methods of and arrangements' for
fitting frames and surfaces, such as sashes and door frames moving or travelling
in grooves.. I fix to the edge of the sash or frame or surface a solid or par-
tially solid cord, rod, bar, strip, or cylinder of caoutchouc, gutta percha, or
their compounds, or similar elastic material, which as the sash or frame or
surface is moved in the groove will travel therewith against the style or jamb
of the fixed frame; or the cord, tod, bar, strip, or cylinder instead of being
fixed to the sash may be fixed to the style or jamb of the frame. Also I fix
springs with rollers or pulleys to the edge of the sash or frame or travelling
surface in such manner that the springs and rollers press against the style or
jamb of the sash or frame or surface as it travels along. Also spiral or other

page_text: springs may be fitted, acting on a false cheek or style between the frames or
surfaces. Also elastic tubes not charged with air or gas under pressure may
be interposed between frames or surfaces. Also,elastic tubes containing a
spiral or other spring may be interposed between the frame and the jamb or
face of the groove within which the frame travels. Also in the groove for
moveable frames or surfaces elastic tubes containing air may be fitted in
connection with a reservoir capable of having its diameter varied so as to put
air within the tubes in a state of pressure or otherwise.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Dales in the Great Seal Patent Office on the 2nd
June 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
DALES, of New Inn, Strand, in the County of Middlesex, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of December, in the year of our
Lord One thousand eight hundred and sixty-three, in the twenty-seventh
year of Her reign, did, for- Herself, Her heirs and successors, give and
grant unto me, the said John Dales, Her special licence that I, the
said John Dales, my executors, administrators, and assigns, or such others
as I, the said John Dales, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and at
all times thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN FITTING MOVABLE OR TRAVELLING FRAMES AND SURFACES,"
upon the condition (amongst others) that I, the said John Dales, my
executors or administrators, by an instrument in writing under my, or their;
or one of their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said John Dales, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following

page_text: statement thereof, reference being had to the accompanying Drawings, that
is to say:
.
My Invention relates to certain improved methods of, and arrangements
for fitting frames and surfaces, such as sashes and door frames, moving or
travelling in grooves, and the object of the improvements is to exclude damp,
dust, noise, and air between such moveable or travelling frames and surfaces
and the fixed frames or surfaces in, on, or against which they travel. Accord-
ing to one arrangement, I fix to the edge of the sash or sliding frame, or
surface, a solid, or partially solid cord, rod, bar, strip, or cylinder of caout-
chouc, gutta percha, or their compounds, or similar elastic material, which, as
the sash frame or surface is moved in the groove of the fixed frame, will travel
with it against the style or jamb of the fixed frame. Or the cord, rod, bar,
strip, or cylinder, instead of being fixed to the sash or sliding surface, may be
fixed to the style or jamb of the fixed frame.
According to a second arrangement, I fix springs with rollers or pulleys to
the edge of the sash frame or travelling surface, in such manner that the:
springs and rollers press against the style or jamb of the fixed frame as the
sash or movable frame or surface travels along.
.'
:
According to a third arrangement, spiral or other springs may be so fitted as:
to act on a false cheek or style between the fixed or moveable frames or
surfaces.
According to a fourth arrangement, elastic tubes, not charged with air or:
gas under pressure, may be interposed between the frames or surfaces.
According to a fifth arrangement, elastic tubes containing a spiral or other
spring may be interposed between the frame and the jamb or face of the:
groove in which it travels.
Also, when in the grooves in which moveable frames or surfaces travel,
elastic tubes containing air are fitted; such tubes may, according to my sixth
arrangement, be connected with a reservoir capable of having its diameter
varied, so as to put the air within the tubes in a state of pressure, or
otherwise.
Having set forth the nature of my said Invention, I proceed, with reference:
to the Drawings, to describe in what manner it may be carried into effect.
DESCRIPTION OF THE DRAWINGS.
The Drawings show the Invention applied to a window of an apartment,
though it may be applied in like manner to other similar travelling frames and
surfaces. In all the Figures A, A, are the sashes, B is the style of the win-
dow frame, C its head, and D. its sill.

page_text: Figure 1. is a vertical section of part of a sash and frame exemplifying my
first arrangement. E is a solid gutta-percha cylinder, cemented in a semi-
cylindrical vertical groove, formed in the edge of the sash style. A. This
groove receives the cylinder E for its whole length, and for about one half of
its circumference, so that as the sashes are moved up and down in the frame
B, the cylinders E travel with them in the groove of the style of the said
frame B; or the cylinders may be cemented in a groove in the frame, and
work in a groove in the sash. Instead of a cylinder E a strip or band of
elastic material may be used. This Figure also exemplifies my fourth arrange-
ment, supposing E, instead of representing a solid cylinder, to represent a
hollow tube, open to the air at top and closed at bottom.
Figure 2 is a front elevation; Figure 3, transverse vertical section; and
Figure 4, horizontal section of my second arrangement. Figure 5, vertical
section on a larger scale, and Figure 6, transverse section of Figure 5.
a is a spring rivetted to the sash style A, and carrying a flanged metal
sheave b, on which is a gutta-percha roller c. As the sash A-travels up and
down in the groove of the frame B, the spring rollers c press against the said
groove. f, h, is an excentric spring regulator, for adjusting the spring a, con-
sisting of a toothed wheel pressing against the spring a and working between
fixed plates g. i is a hole for admitting a key by which the wheel f is moved
between the plates; an excentric spring catch h, (fitted on one of the plates g,)
takes into its teeth, to prevent it from recoiling; the spring a is thereby kept
to its work.
"
Figure 7 is a vertical section of my third arrangement, in which a false
style F is fitted between the sash A and frame B. d, d, are spiral springs,
fastened to the style F, between it and the groove of the fixed frame B, to
press the style F towards the sash, e is a gutta percha block, fitted in a niche
in the sash style A, and travelling with it against the false style F.
The springs may be enclosed, according to my fifth arrangement, in an
elastic tube..
In my sixth arrangement tubes, charged under pressure with air or gas,
similar to the arrangement described in Meears' Patent, No. 177, dated 21st
January 1868, communicate at their lower end with a vessel of flexible or
elastic material, forming a reservoir of compressed air, and fitted with valves,
worked by screws or otherwise, for admitting air into it, and discharging it
when compressed into the tubes. The vessel is fitted with a screw and sliding
collar, or other ordinary means, whereby its diameter may be varied so as to
put the air within it in a state of pressure, or otherwise.
Having now described the nature of my said Invention, and in what manner

page_text: the same may be performed, I declare that I am aware that the use of elastic
tubes, charged under pressure with air or gas, and fitted between sashes and
their frames, is a known arrangement, and I lay no claim thereto under the
present Patent, when uncombined with a reservoir, as before described and
herein-after claimed. And I declare that I claim, as constituting my said
Invention,
First, the employment of a solid, or nearly solid cord, rod, bar, strip, or
cylinder of elastic material, as described.
Second, the employment of springs combined with rollers or pulleys, as
described.
Third, the employment of springs combined with a false style or cheek, as
described.
Fourth, the employment of elastic tubes not charged under pressure with
air or gas, as described.
Fifth, the employment of elastic tubes containing springs, as described.
Sixth, the employment of elastic tubes in combination with a reservoir
capable of having its diameter varied so as to put the air or gas in the tubes.
in a state of pressure, or otherwise, as described.
In witness whereof, I, the said John Dales, have hereunto set my
hand and seal, this Second day of June, in the year of our Lord
One thousand eight hundred and sixty-four.
Witness,
