1 Claim.
This invention relates to weatherstripping and
is particullarlyadapted to closing the crack be
tween a door and a raised threshold.
Included among the objects of the invention
5 are the following: To provide »a weatherstrip
ping which is inexpensive. to manufacture; to
provide la weatherstripping which can be easily
installed; to provide a weatherstripping which
effectively shuts out inclement weather; to pro
10 Vide a weatherstr-ip'ping which is not unsightly
nor in the way; and to provide `a Weatherstrip
ping which has a relatively long life.
The manner of accomplishing the foregoing
objects, as well as further objects and `advan
15 tages, will be made manifest in the following
description taken in connection with the Kaccom
panying drawing in which;
Fig. 1 is a perspective view of the lower end
of a doo-r equipped with a preferred embodiment
20 of the invention.
Fig. 2 is `an enlarged, detailed, cross-sectional
View taken on the line 2.-,2 yof Fig. 1 and illus
trai-,ing the condition of the weatherstripping of
my invention when the door is open.
Fig. 3 is a View similar to Fig. 2 illustrating the
condition of the Weatherstripping of my inven
tion with the door closed.
Fig. 4 is a view on a reduced scale taken in
the direction of the arrow 4 in Fig. 3 and illus
30 trating the manner in which the weatherstrip
ping of my invention entirely seals the crack at
the bottom of the door.
Fig. 5 isa diagrammatic View illustrating the
condition of the rubber member of the weather
35 stripping of my invention before it is applied to
the lower edge of the door.
Referring specifically to the drawing, I have
there shown a door I0 and a raised threshold II,
the crack I2 between which is shown in Fig. 3
40 as closed by the weatherstripping of my inven
tion. This weatherstiipping is practically com
bined with the door Il? and 4threshold Il, lower`
edge I 3 of the door It being specially beveled to
provide for the application of the sealing mem
45 ber I4 of my invention. The member I4 is
preferably cast of rubber in one piece and in
cludes a butt portion I5 and a tubular portion
IG. When cast it has a cross section as shown
in Fig. 5 where it is seen that the tubular por
50 tion I5 is symmetrically disposed with respect to
the butt portion I5.
Means are provided for fastening the sealing
member IB to the edge E3 of the `door III, this
means consisting of a plate 2i), having `a flange
55 2| along one side thereof and being perforated to
(Cl. :Z0-69)
receive nails 22 which, as shown in Figs. 2 and 3,
extend through the butt portion I5 of the mem
ber Iâ and into the door I il. When the sealing
member I4 is thus applied to the door edge I3,
the upper face of the
mally has l‘a concavity
against the base i3 of
in Figs. 1, 2 and 3. It
member I4, which nor 5
23, is caused to lie flat
the door Il), as shown
is `also noted that when
the member I4 is applied, the tubular portion I5
lies `against and under that portion of the edge
I3 of the door i9 which is adjacent to the verti~
cal face 25 of the door IIJ, toward which the vdoor
swings when it is opened, as shown in Fig. 2.
It is to be noted that when the door is thus
opened, vas shown in Fig. 2, the tubular portion 15
I6 of the member I4 expands by its own natural
resiliency into a position Where its lower edge ex
tends a substantial distance below the level of
the upper face 26 of the threshold II.
When the door Ill is closed, however, as shown
in Fig. 3, the tubular portion I6 is slightly col
lapsed, thereby eiîecting a snug seal between
threshold I I and the door IB. It is also to be
noted in Fig. 4 that this seal extends the full
width of the door Iû, thus bringing the member
I4 into airtight Contact with the door jambs 2l
and 28.
In Fig. 1 it is to be noted that nails 22 are al
ternately placed adjacent to the opposite edges
of the metal plate 20. Attention is also directed 30
to the manner in which the flange 2I of the plate
2û embraces the free end of the butt portion I5
of the member I4, thus giving a neat appearance
to the plate 20, as well as stiiîening this.
It is further evident that the manner in which
the member Iâ is manufactured to produce a con
cavity 23 in opposite faces thereof results, when
the member I4 is applied to the lower edge of
the door, in the tubular portion I8 thereof being
held upwardly under the strain of its own resil
iency against the door edge I3, thus effectively
preventing any sagging of the member Ill.
In Figs. 1, 2, and 3 I have shown the weather
stripping of my invention in use with both ends
of the tubular portion IS left open. When thus
used, my weatherstripping operates satisfactorily
as hereinabove described.
In some instances it
is preferable, however, to have the ends, at least,
of the tubular portion IS of the weatherstripping
I4 closed. In such cases I íill opposite ends of the
tubular portion I6 with a yieldable filler SIB, which
may be made of sponge rubber, loose wool or the
like. If desired, of course, the entire interior of
the tubular portion I5 may be filled with the ma
terial 30.
Owing to the fact that the ends of the weath
erstripping I4 are tightly pressed against the
jambs 2l and 28 when the door is closed, access to
the interior of the tubular portion I6 is per
missible only when the door is open. This being
the case, no opportunity is aiîorded for the build
intersects with said hinge face being disposed a
relatively great distance from said threshold so
that said surface constitutes a lower edge of said
door which is beveled relative' to said door faces
at a substantial angle; a Weatherstripping mem
ber formed of rubber and including a tube of sub
ing of nests in this weatherstripping by insects
stantially pear-shaped cross section, there being
and the like, and for this reason it is unnecessary
to close the ends of the tubular portion I6.
What I claim is:
In a threshold weatherstripping, the combina
tion of: a raised threshold; a door hingedly sup
ported in position above said threshold about a
hinge axis adjacent a given face of said door;
15 jamb means for stopping said door in position
over said threshold by engagement with the op
formed integral with the stem edge thereof a rel
atively thin attaching flange; and means for se
curing said ñange to said door so that said mem
ber lies snugly against said beveled surface with
posite face of said door, the lower edge of said
door being provided with a relatively ñat surface
extending substantially from one of said faces to
20 the other, said surface at its juncture with said
jarnb face being disposed a relatively short dis
tance from said threshold, said surface where it
said flange extending beneath that edge portion
of said surface which is disposed a relatively
short distance from said threshold and said tubu
lar portion of said member lying beneath that
portion of said beveled surface which is disposed
a relatively large distance from said threshold,
said tubular portion of said member extending
downwardlybelow the level of the upper surface
of said threshold when said door is open.
