Chelsea, in the County of Middlesex, for the Invention of "AN IMPROVED
METHOD OF EXCLUDING DUST, WATER, AIR, AND OTHER EXTRANEOUS MATTERS.
PROVISIONAL SPECIFICATION left by the said James Anning Gollop at
the Office of the Commissioners of Patents, with his Petition, on the
20th May 1856..
I, JAMES ANNING GOLLOP, of 74, Lower Sloane Street, Chelsea, in the
County of Middlesex, do hereby declare the nature of the said Invention of
"AN IMPROVED METHOD OF EXCLUDING DUST, WATER, AIR, AND OTHER EXTRANEOUS
MATTERS FROM DOORS, WINDOWS, GLASS SHOW-CASES, AND SUCH LIKE CONSTRUC-
TIONS," to be as follows:-
This Invention consists in adapting vulcanized india-rubber, or other suit-
able clastic tubing of small size, to those parts of the framing of doors against
which the door rests or abuts when closed, so that the closing of said door
[compresses the said elastic tubing, and thus effectually excludes the entrance
of dust and air, and obviates the objection attending "slamming" of the door,.
the aforesaid elastic tubing serving as a cushion for the door to strike against..
As regards the adaptation of this Invention to windows, glass show-cases,
and such like constructions, it will appear evident that by a proper application
of the elastic tubing, dust, water, air, and other extraneous matters may be.
effectually excluded therefrom in a simple and efficient manner.

is to be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say:-
My Invention relates, firstly, to doors, and consists in adapting thereto
vulcanized india-rubber or other suitable elastic tubing of small size to those
parts of the door jamb against which the door rests or abuts when closed, and
also to the lower rail of the door, so that the closing of the door compresses
the aforesaid elastic tubing, and thus effectually excludes the entrance of dust
and air, and obviates the objection attending "slamming" of the door .by.

entrance of: dust, air, and other extraneous matters in a more simple and
efficient manner than heretofore.
In order to explain my said Invention as completely. as possible, I now
proceed to describe the best means I am acquainted with for carrying the
same, into practical effect, reference, being had to the illustrative Drawing
hereunto annexed, and to the numeral figures and letters of reference marked
thereon respectively,.as follows:-

DESCRIPTION OF THE DRAWING.
..:
Figure 1 is a horizontal section of a door, shewing the mode of adapting the
elastic tubing thereto, and the position it would occupy in the jamb of the
door, supposing the door to be open: Figure 2 is a section of the door, closed!
Figure 3 is a, horizontal section, through the lower rail of the door, shewing
the mechanism for compressing the tubing at the bottom of the door.
Figure 4 is a longitudinal and vertical section, taken through the bottom
rail and jamb. of said door. Figure 5. is a longitudinal vertical section of a
window sash (open), and frame, shewing the manner in which I adapt the
elastic tubing thereto, and operate thereon by the closing of the said sash.
Figure 6 shews the position of the elastic tubing when the window is open,
An important feature in this part of my said Invention consists in combining
certain mechanism with the elastic tubing and the window sash, whereby the
lowering and entire closing of the said sash causes the tubing to be forcibly.
pressed against. the sides of the frame in which the sash slides, or moves,
thereby effectually excluding the entrance of air, dust, &c. The upward
movement of the sash relieves the pressure of the tubing, and allows the sash
to move freely in the frame. Figure 7 is a section of the elastic tubing which
I employ. Figure 8 is a horizontal section of one of the rails of the window.
sash, shewing the position of the groove therein. At each of the foregoing.
Figures. I employ similar letters of reference to denote corresponding parts; in
so far as such, parts appear or can be seen at each of such said Figures
respectively. At Figures 1 and 2, A, A, is the door frame, to which is hinged
the door B in the ordinary way; C is a

a, a, to the sides and top of the door
any convenient and suitable manner.;
tubing may be fastened to the door B. By this application of the aforesaid
elastic tubing it will appear evident that the shutting of the door will compress
piece of elastic tubing of the shape
This tubing I securely fix by the parts,
jambs, and under part of the door, in
or, if desirable, the aforesaid elastic

page_text: said tubing, and thus exclude draughts at the sides of the door, and obviate
the noise occasioned by slamming doors of the ordinary kind. If necessary,
draughts of cold air may be prevented from entering at the top and bottom
of the door by arranging the elastic tubing C, and operating thereon by
certain mechanism exhibited at Figures 3 and 4, where A marks the bottom
rail of a door; B, a bell-crank lever connected by a pin in a recess formed
in the edge of the door to receive it, one end of this lever protrudes through
a hole in the door rail, and the other end of said lever is connected to a
sliding piece D, of which there are two of similar construction to that here-
after described and represented at Figures 5 and 6. E is a check spring, one
end of which is fastened to the door rail, and the other end is connected to
the upper 'sliding piece D. The effect of this arrangement is as follows:-
When the door is open the tubing C is flush, or nearly so, with the top and
bottom rails of the door, so as to enable it to open freely; but upon closing the
door, the projecting part 6 of the bell-crank lever B, coming into contact with
the door jamb, causes the other arm of said lever to be moved, and with it the
sliding pieces D, D, by which the tubing C is forcibly pressed and held by
the catch of the lock, and in this manner and by these means I exclude
draughts or currents of cold air from doors. Upon opening the door, the
spring E draws back the sliding pieces D, D, thus allowing the tubing to
retire free from the floor or upper part of the door jamb, or both, as desired.
I now proceed to describe my improved method of excluding dust, &c. from
windows, as exhibited at Figures 5 and 6, said method being also applicable
to the construction of glass show-cases and such like constructions. At
Figures 5 and 6, D is a window frame; E and G are window sashes fitting
thereinto. The edges of these sashes have grooves formed along them, as
at d, Figure 8, into which I place two sliding pieces of wood or metal H, I, of
the shape exhibited at Figures 5 & 9. The bottom of each of the grooves d
are hollowed out to receive the parts h of the pieces H, said pieces being
connected together by a piece of elastic K and pieces of wood or metal a, a,
which pieces take loosely into recesses c, c, formed in each of the pieces H, I,
as exhibited at Figure 9. L is a piece of elastic tubing (of the shape exhi-
bited at Figure 7), the part a of which is securely fixed by screws or otherwise
to a rebate formed on the edge of the window sash, so that when the parts
are in the position exhibited at Figure 5 the surface of the elastic materiál is
flush, or nearly so, with the edge of the sash frame. The above arrangement
is employed at each side of each sash, the top edge of the top sash and the
bottom edge of the bottom sash simply having a groove or rebate formed:
therein to 'receive about half the diameter of the elastic tubing.L. It will be

page_text: seen, upon referring to Figure 5, that one end of each of the sliding pieces H
projects below the edge of the lower sash for the following purpose:-Suppose
the lower sash to be up, as at Figure 5, and the pieces H and I to be in the
position there exhibited, it will appear evident that there will be no pressure
or binding of the sash in the frame. But upon closing or pulling down said
sash, the projecting parts. i of the pieces H, coming into contact with the
bottom part of the sash frame, will force such pieces along the grooves d; and
the piece I being prevented from moving laterally, the effect of the sliding
piece H will be to force the pieces a, a, into a straight line, as at Figure 6,
thereby pressing the elastic tubing L close against the sides of the sash frame,
thus forming an air-tight joint at such part; and this mode of operating upon
the elastic tubing applies also to the top sash when moveable, the two sashes
being held in that position by a catch of the ordinary kind placed at the
meeting rails of the two sashes; and this applies also to glass show-cases and
such like constructions. .
Having now fully described and ascertained the nature and object of my
said Invention of "An Improved Method of Excluding Dust, Water, Air, and
other Extraneous Matters from Doors, Windows, Glass Show-Cases, and such
like Constructions," I would remark in conclusion that what I claim as my
Invention is, the combining of the sliding pieces H, I, and a, a, with the
elastic tubing L, and operating thereon by the opening and closing of the
window and door respectively, or other similar construction, for the purpose of
excluding dust, water, air, and other extraneous matters therefrom, as above
stated.
In witness whereof, I, the said James Anning Gollop, have hereunto
set my hand and seal, this Twentieth day of November, in the year
of our Lord One thousand eight hundred and fifty-six.
