IMPROVEMENTS IN WEATHER STRIPS
Year: 1884

page_text: COMPLETE SPECIFICATION.
I, HERBERT JOHN HADDAN, of the firm of Herbert and Company, Patent
Agents, of 67, Strand, in the City of Westminster, Civil Engineer, do hereby
declare the nature of my invention for IMPROVEMENTS IN WEATHER STRIPS, 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 class of weather-strips in which an elastic packing-
strip is secured to a firm sustaining strip which receives the nails or screws by
which it is attached to the parts adjacent to the crevice to be closed.
The invention consists in an improved construction and combination of the
constituent parts of the weather-strip, whereby increased stability, durability and
efficiency is imparted thereto as hereinafter more fully explained, and specifically set
forth in the claim.
The invention is fully illustrated in the annexed drawing wherein Figure 1 is
an isometric view of a portion of a window provided with the improved weather-
strip Figure 2 is a detached enlarged plan view of the weather-strip, and Figure 3
is a transverse section of the same.
Similar letters of reference indicate corresponding parts.
A represents the elastic packing strip composed of sheet rubber or other
suitable elastic material, and B is its sustaining plate or strip formed of sheet
metal.
The elastic strip I first fold longitudinally along the centre thereof as indicated
by the reference letter b and then fold a portion along the two edges back upon
itself and secure the said strip to the metal strip B by folding the two edges of the
latter toward each other as shown at a a¹ in Figure 3, and inserting underneath
one of said metal folds a the two edges of the elastic strip A and underneath the
other metal fold a¹ the four fold portion of the elastic strip and pressing the metal
folds down upon the embraced portions of the strip A so as to securely retain the
same. The first longitudinal fold b of the elastic strip projects from under the
metal strip B. and forms a tubular packing, which lies across the crevice to be closed
as represented in Figure 8 of the drawing.

page_text: It will be observed that by folding the metal strip in the manner shown and
described I reinforce the edges thereof and materially stiffen the strip, and at the
same time form thereon two separate and distinct bearings, one of which presses
and binds the elastic strip against the jamb of the door or window to which the
weather-strip is applied, and thus more securely fastens the elastic strip. Further-
more by the described construction and combination of the constituent parts of
the weather-strip the latter is relieved of the exposure of raw edges of either the
rubber or metal and presents a neat and perfect finish.
In order to further strengthen the metal strip B I make the same concavo-
convex in cross section and secure the elastic strip in the concavity of the metal
strip by folding the edges of the latter upon the elastic strip in the manner
hereinbefore described.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is,
The elastic strip folded once upon itself along the centre and back again from
the raw edges part way the width of the double portion, in combination with the
metal strip formed concavo-convex in cross section and having its edges folded into
the cavity part way toward the centre thereof and embracing respectively the raw
edges and four fold edge of the elastic strip substantially as described and shown.
Dated this 19th day of February 1884..
