of Doors Windows, Hatches, Ports, and the like.
I, JAMES HAMILTON, of Ardedynn, Kelvinside, near Glasgow, Lanarkshire,
Ship Builder and Engineer, do hereby declare the nature of this invention
to be as follows:-
The object of this invention is to provide improved means, whereby the joints
between the opposing surfaces of a window, door, or hatch, and the framework
against which such is brought into direct contact, can be rendered air, water,
dust, and weather tight, by the employment of flexible packing.
The type of packing to which this invention relates is of flexible tubular
description, located in the framework, and arranged so that the closing part, such
as the window, when shut, directly abuts against such packing, and this inven-
tion particularly refers to the arrangement of the packing, and to the construction
of the framework to receive the packing.
According to this invention, within the frame to which the window is attached,
and upon the face of the frame against which the window closes, a groove is
formed, of approximately circular cross section with a narrow opening in the
face of the framework. The groove is arranged near the interior edge of the
frame and extends the whole distance around same.
Within the groove is inserted a ring of elastic tubing, fitted with a valve or
valves, so that the tubing may be inflated; upon inflation taking place a part of
the tubing is forced well through the narrow opening of the groove, and is
caused to project evenly and continuously, beyond the surface of the frame,
along the entire length of the groove.
The window sash is so arranged, that when the window is closed, the sash comes
into contact with the projecting part of the tubular ring, and bears upon same.
The pressure with which the sash is caused to press upon this pneumatic packing,
is regulated by the fastener.
By this arrangement, the pressure of contact at all parts between the sash and
the pneumatic tube, is equal.
It may be desirable to form the part of the tubular ring, which is caused to
project through the aforesaid groove, of thicker or tougher material than the
body of the tube, or to fit a pneumatic tube within another tube.
Dated this 29th day of September 1898.

of Doors, Windows, Hatches, Ports, and the like.
I, JAMES HAMILTON, of Ardedynn, Kelvinside, near Glasgow, Lanarkshire,
Ship Builder and Engineer, 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 provide improved means, whereby the joints
between the opposing surfaces of a window, door, or hatch, and the framework
against which such is brought into direct contact, can be rendered air, water,
dust, and weather tight, by the employment of flexible packing.
The type of packing to which this invention relates is of flexible tubular
description, located in the framework, and arranged so that the closing part, such
as the window, when shut, directly abuts against, such packing, and this inven-
tion particularly refers to the arrangement of the packing, and to the construction
of the framework to receive the packing.
In order that my invention may be readily understood I will describe same
with reference to the accompanying drawings, whereon is shewn several views of
a deck-house window by way of example, fitted with my improved packing. Fig. 1
is an elevation of the window and its frame, the window being shewn closed.
Figs. 2 and 3 are longitudinal sections drawn to a larger scale than Fig. 1, (being
about full size) shewing respectively the joint at the hinge side and the joint at
the fastener side. Fig. 4 is a vertical transverse section taken on the line X Y
of Fig. 3, and Fig. 5 is a sectional view shewing a modified construction of the
flexible pneumatic packing.
According to this invention, within the frame A to which the window B is
attached, and upon the face A¹ of the frame A against which the window sash B'
closes, a groove is formed, of approximately circular cross section with a narrow
opening in the face A' of the framework A. The groove is arranged near the
interior edge of the frame A and extends the whole distance around same.
Within the groove is inserted a ring of elastic tubing C fitted with a valve or
valves C, Fig. 3, so that the tubing may be inflated or expanded; upon inflation
or expansion taking place a part of the tube C is forced well through the narrow
opening of the groove as shewn at Figs. 2, 3 and 4, and is caused to project evenly
and continuously, beyond the surface A¹ of the frame A, along the entire length of
the groove.
The window sasli B₁ is so arranged, that when the window B is closed, the
sash B¹ comes into contact with that part of the tubular ring C which projects
beyond the face of the frame A and bears upon the projecting part of the
tube C.
The pressure with which the sash B¹ is caused to press upón this inflated or
expanded tubular packing C is regulated by the fastener D.
The fastener shewn in the drawing at Fig. 3, is composed of a lever pivotted
to the fixed frame A one arm of which lever acts against the window sash B¹,
or against a plate fixed thereto as shewn; this plate B2 may form an inclined
plane as shewn at Fig. 4 whereby the rotary movement of the arm, acting thereon,
will force the window sash A¹ upon the projecting part of the pneumatic tube C.
Other constructions of fastening devices may be employed adapted to so force the
window frame on to the packing, such as screw fastenings and the like.
By this arrangement the pressure of contact, at all parts between the sash and
the tube, is equal.
It may be desirable to form the part of the tubular ring which is caused to

page_text: project through the aforesaid groove of tougher or thicker material, as at Fig. 5,
than the body of the tube is composed of, or to fit a pneumatic or impermeable
tube within another tube as is also shewn at Fig. 5 aforesaid.
In some cases I may make the outer casing of the tube C of asbestos fabric, or
of other non-inflammable material to obviate liability of damage by fire.
The tube may be made if so desired, not in the form of a complete ring, instead
of which the ends of same may abut on each other or overlap in the groove, and
moreover the tubes may contain or be held expanded by gas or fluid instead of
air; all the tubes of several windows may be connected by tubular connections
and be simultaneously maintained under pressure derived from one pressure tank
or cylinder.
If so desired, the arrangement of the tube may be reversed, that is, the tube
may be fitted in a groove in the window sash and abut against the framework.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. In that class of windows, doors, hatches, ports, and the like, wherein a
hinged part closes directly against and abuts upon a fixed frame, the construction
and arrangement of air-tight packing, composed of a closed tube, located in a
groove extending around the frame, the groove having a narrow opening around
the face of the frame, and being larger in cross section within the frame, a
valve or tubular connection on the tube by which the latter may be expanded by
internal air or fluid pressure, a beading of the flexible tube being thereby forced
through the narrow opening of the groove, and caused to project beyond the
faces of the frame, and fasteners to the hinged windows or the like, by which the
frame of the latter may be forced upon the projecting bead of the tube, sub-
stantially as described.
2. In that class of windows, doors, hatches, ports and the like, wherein a hinged
part closes directly against and abuts upon a fixed frame, the arrangement and
construction of tubular air tight packing, all substantially as described and illus-
trated with reference to the accompanying drawings."
