CHIMNEY CAP LINK
FIELD OF THE INVENTION
[0001] The present invention generally relates to a wood or combustion stove
or furnace
installation, and more particularly, to a frame mounted slidable pipe link
assembly and its utility
in providing quick access to an open flue, and by means by which the flue may
be rapidly
coupled to a stove or other combustion device.
BACKGROUND OF THE INVENTION
[0002] Combustion heating units, such as furnaces or stoves, whether utilizing
wood or other
forms of fuel to generate heat, all require a smoke evacuation conduit, a flue
pipe leading to a
chimney, is common place.
It is such that these are popular devices for heating in residential and
commercial buildings.
[0003] When such a unit is not in use, however, the opening within the unit,
connected to a flue
leading outside forms a passage, through which heated air or cooled air can
escape from the
interior of the building.
A frame mounted slidable pipe link assembly, providing instant access to a
flue, when it is not in
use, said assembly when installed preferably at the exterior wall hole, at the
bottom of the
chimney, inside the building, would provide simple access to open a flue line
at the wall in order
to install a cap directly over and into the wall hole opening, at the wall or
to clean out the inner
chimney bottom or to simply inspect the inside of the flue at this important
location in the flue.
In there lies the usefulness and utility of a chimney cap link. Or a frame
mounted slidable pipe
link assembly. The multi-purpose utility of the said device is evident.

[0004] Few innovations for quick and easy access to a flue have been
previously put forth in
prior art. For example, EP Pat. No 2149751A2 to Thomas, Pierre, Druette and
Coiner discloses a
"device of preparing for a conduit ensuring connection between a heating
appliance (standard
stove or cooker) and a flue of smoke leading to a chimney, it still relates to
the process of setting
opens some of such a device of preparing." Note the single purpose and utility
of this device is to
introduce to an already standard flue pipe an additional outer sliding shield
cover, encasing the
standard flue pipe concentrically sliding one into the other and introducing a
collar spacer ring at
one extremity of both pipe lengths so as to allow for, when one pipe length is
slid into the other,
pipe lengths are interlocked and slid up and down. This newly attached sliding
shield cover
allows for an air chamber space within the two interlocked pipe lengths and
two openings or
vents are present and situated at one extremity of each sliding pipe. One for
the top end and one
for the bottom end. When installed the sliding pipe lengths serve to adjust
the vent hole openings
permitting increased or decreased circulation of colder air entering the air
chamber, between the
parallel walls of the main flue and the additional two cylindrical
interlocking sliding cover parts,
then air rising up to the top opening vent, venting out the hot air
accumulating in the upper
chamber area. Thus creating an air insulated barrier of a double wall nature,
with the outer cover
surface cool enough to touch and thus creating a safer characteristic of said
device permitting by
law the flue pipe device to be located closer to interior walls of the
building. However, it does
not open or provide any access inside the flue itself, which presents again
another major
difference. In addition there is no seal as compared to the frame mounted
slidable pipe link
assembly. Another difference is stated, the device is made to be installed in
a vertical position.
Note the framed slidable pipe link assembly is constructed to be installed at
all angles or slope,
either vertical or horizontal or yet again at a slope of any angle. This fact
constitutes a major
CA 02858528 2015-12-09
3
difference with its enhanced versatility and wider or broader applications
such as a wall
connection, as compared to the previously stated EU patented prior art.
The two spacer rings in the EU patented device are similar to the two spacer
rings used in the
frame mounted slidable pipe link assembly device. However there utility,
purpose and function
are different , in such that, yes the EU spacers serve as an abutment in
between the sliding
cylinders in order for them to snugly fit within one another and slide easily
and also they serve to
create an open air space between said parallel walls. Note this is where their
resemblance ends.
The spacer rings within the frame mounted slidable pipe link assembly actually
do more. They
are present in order to provide a concentric frame platform around the pipe
ends in which allows
for the attachment of the shorter interior seal walls within the sliding seal.
Also they constitute
the parts or location within the seal which stops any leakage eminating from
within a flue pipe
by being the abutment part inner surface within the seal, where and when the
sleave is pulled and
slid tight, the shorter inner walls abut squarely against the spacers tightly
and block any leakage
of the conduit or flue. Thus constituting a two inner point of contact sliding
seal, which can be
applied to many conduits of smoke and also liquids, such as water, pulp,
steam, oil and more.
[0005] Therefore, a heretofore unaddressed need still exists in the art to
address the
aforementioned deficiencies and inadequacies.
SUMMARY OF THE INVENTION
[0006] In one aspect the present invention relates to a stove or combustion
unit flue coupling
device, permitting an opening and access inside the flue. In one embodiment,
the stove smoke
flues new framed slidable pipe link assembly, includes two, 2 pipes of a set
length and same
diameter, three frame rods of solid heat resistance material, bent to a 900
angle, in from each end.
Attached to the two said pipes, by welding or other means, parallel to the
pipe exterior walls
CA 02858528 2015-12-09
4
which are lined up, end to end, and linking the two flue pipe lengths, while
also leaving a gap or
empty open space in between the two pipe ends. The frame rods are to be
attached in a triangular
fashion. Another pipe for the sliding sleave seal, of a longer length but
larger diameter is also
present, serving as the body of the moving part, the sliding sleave seal being
of greater diameter
than the two initial pipe lengths, it can be slid left and right over the pipe
of the link and covering
or revealing the open gap in the stove pipe line. At the output end of the
sleave, a reducing
concentric pipe piece is attached to reduce the diameter of the head of the
sleave down in order
to fit over and connect to the pipe end, at the output end of the link
assembly. The open output
pipe length that is within the link assembly.
100071 In one embodiment the frame mounted slidable pipe link assembly,
entails a seal feature
which serves to seal the slit that exist inside, between the sliding sleave
wall of one diameter and
the link pipe wall of standard diameter. This interior slit or crack, that is
present, is the open slit
of air in between the sliding sleave wall and the pipe wall in which the
sleave slides over when
slid one within the other.
By adding and attaching by way of welding or rivets, one new shorter semi-
length of flue pipe
of a different smaller diameter, being shorter in the the length of the
sliding sleave, by way of
inserting it within the sleave at its intake end, and sliding it in flush,
then inserting a metal spacer
ring in between the pipe walls at the intake end, then affixing them together
to create the bottom
double wall section of the sliding seal sleave. The said spacer is providing a
gap in between the
pipe walls, this gap enabling shorter pipe walls to slide into one another and
thus constituting one
half portion of the sliding pipe seal.
The other half of the seal is present at the output end of the number 2 pipe
part, in the link. Again
another shorter pipe, of this time, a larger diameter than the standard
diameter number 2 pipe, but
CA 02858528 2015-12-09
again being shorter than the length of the sleave. This new shorter length
pipe is slid down and
over the number 2 pipe in the link, down again. Flush with the pipe end, then
another metal
spacer is inserted within the now parallel pipe walls, encircling the pipe
wall within and creating
another small gap in between and allowing the other shorter wall to also slide
in and out.
By sliding the head of the sleave up over the number 2 pipe, then pulled
together tightly, the new
shorter walls that were added, interlock then abut squarely with the spacers
creating a four wall
seal chamber with two points of contact barriers contained within.
The inner slit present in the seal wall, is protected against the leakage of
creosote and such by a
protective inner cylindrical type shield, which protrudes down within and
overlapping and
bypassing the slit.
[0008] In one embodiment, the chimney cap link device further includes, an
insulated flue cap, to
be left hanging, when not in used, on the units frame by way of a hooked metal
handle that is
incorporated onto the cap which also embodies an inner concentric metal wall
cavity containing
two and one half (2 Y2) inches of insulation, capped with a concentric cover
plate. However
although, spoken of here the insulated double wall cap is not and does not
form part of this
claim.
[0009] In one embodiment, the frame mounted slidable pipe link assembly
further includes two
metal flexible leaf snap in locks. Measuring four inches by one inch in width
with one sixteenth
of an inch in thickness. Attached to the lower area of the frame, they rise up
in a slope leading
under the protruding bottom of the sliding sleave when it is locked in place.
Bent outward at the
top ends one inch, then upward one inch, in which providing small handles to
grip, and pull out
or push and snap in against the pipe wall.

DETAILED DESCRIPTION OF THE INVENTION
[0020] The present invention is more particularly described in the following
examples that are
intended as illustrative only. Since numerous modifications and variations
there in will be
apparent to those skilled in the art. Various embodiments of the invention are
now described in
detail. Referring to the drawings, like numbers indicate like parts throughout
the views. As used
in the description herein and throughout the claim that follows. The meaning
of "a", "an", and
"the", includes plural reference unless the context clearly dictates
otherwise. Also as used in the
description herein and throughout the claim that follows, the meaning of "in",
includes "in" and
"on" unless the context clearly dictates otherwise. Also ,in the construction
of the invention, all
parts are attached by way of either welding and rivets and threaded nuts that
attach the frame
parts.
[0021] The description shall be made as to the embodiments of the present
invention in
conjunction with the accompanying drawings in FIG. 1 - 9. In accordance with
the purposes of
this invention, as embodied and broadly described herein, this invention, in
one aspect relates to
a combustion stove or furnace flue opening link assembly device. It includes a
rigid metal frame
(25), of three solid metal rods (24), threaded at the ends and bent uniformly
at a 90 angle, one
and one half inch 1 Y2 in from the ends. This frame (25) then attached in a
triangular pattern,
parallel to the two pipes contained within the link (2), (4), with angled ends
inward connecting
and attached to the outer pipe walls of the two pipe parts of the link, (2)
and (4), when they are
aligned end to end, leaving an open space in between. Thus the frame (25)
permanently linking
CA 02858528 2015-12-09
11
these two aligned pipe parts in a fashion that permits a sliding sleave to
slide back and forth over
said two pipe parts, (2) and (4).
[0022] This sliding sleave (1) is of slightly greater diameter than the two
previous standard sized
pipes (2) and (4) and is slid over back and forth on the 2 pipe parts of the
link. Being part of an
inner sliding seal, the sleave slides easily left or right thus opening and
revealing the open space
that exist between both pipe ends. Or when slid up tightly and closed, creates
an inner four wall,
two point of contact chamber seal that surrounds the pipe wall and seals the
existing inner wall
slit from the sliding sleave. The framed sliding pipe link assembly is
intended for use in all
regular standard flue pipe diameters. The device is intended and most
effective when installed at
the exterior outer wall or ceiling flue hole, which leads out of the structure
into the chimney
outside, where it's cold. Thus the link provides, access inside the flue,
exactly at this key location
within the structure, where an insulated, double wall chimney cap can be
inserted directly into
the cold exterior wall and block the cold out, and also being the key location
to clean out the
chimney without dismantling anything and also for internal inspection of the
flue or conduit.
[0023] Refering to FIG. 1 ¨ 9, the framed mounted slidable pipe link assembly
device, FIG. 1,
includes a sliding sleave (1), made of standard flue pipe, but of a slightly
larger diameter. The
sleave (1) also has attached at its bottom end, a new shorter length pipe (9),
of slightly smaller
diameter, and being of shorter length than the sleave (1). When (9) is
inserted into the bottom
end of the sleave (1) a metal spacer (22) is also inserted in a concentric
manner, where the spacer
is now situated in between the now parallel pipe walls and flush with the pipe
ends which are
also flush. When, attached we have two walls on the lower end of the sleave
(1). Then a second
semi length pipe (9), being the same length as the first, but of larger
diameter, is fitted down and
CA 02858528 2015-12-09
12
over pipe part (2) until the ends are flush, then again a concentric spacer
(22) is attached in
between the pipe walls flush with ends. Please refer to FIG. 6.
Like illustrated in FIG.'s 2, 3 and 4, the device of preparing being the frame
mounted slidable
pipe link assembly understands: a cylindrical sleave (1), made up of more than
just an inner
double wall (9) on its lower end but also contains other parts. Illustrated in
FIG. 7 is the inner
shield (5) this being a cylindrical and slightly cone shaped metal tube (5)
that when slid down
into the top of the sliding sleave (1) until flush and attached around the
top, it, this shield (5)
protrudes down within the sleave (1) and by-passes the inner wall slit that is
present within the
sliding link wall, thus overlapping the wall slit inside and protecting the
inner seal from any
creosote leakage and the likes. Being attached to the sliding sleave (1), the
shield (5) also travels
left or right along with the sleave.
Also depicted in FIG. 7 is the reducing upper end part (23) pipe piece of the
sleave (1), whereas
when attached concentrically over the sleave (1), it (23) serves to reduce
down to the standard
diameter to connect to the crimped top end pipe (4) of the link.
[0024] Depicted in FIG. 1 is one of two metal handles (26) of a flat surface
grip style, attached.
Also depicted are two metal flexible spring leaf locks (8), made of thin flat
metal and bent at the
top outward horizontally for an inch, then bent up vertical for one inch to
form a flat pull grip,
when firmly attached to the lower inner frame (25) and at a slope in which
they abut slightly to
the sleave wall they can be manipulated to snap into locking position or be
pulled out to unlock
the seal.
[00251 illustrated in FIG. 8 is a detailed part by part depiction of a double
wall, hooked handle,
insulated, chimney flue cap (3). By utilizing a regular standard metal chimney
flue cap (18) a
hooked metal handle (12), is attached within the cap (18), at the center, then
bending outward at
CA 02858528 2015-12-09
13
the center of the cap facing, a threaded bolt (21), is inserted through the
center facing and leading
directly through the unit and protruding out the other end. Then an inner
concentric metal
cylinder (16) is fitted within the cap (18), being of smaller diameter than
the standard cap (18), it
is the new inner lining wall attached down in the cap (18) to the inner facing
wall. Thus
providing for the double wall nature of the cap (3) creating an inner core for
insulation (15) to be
inserted. A flat concentric metal cover plate (14) is then fitted over the
exposed insulation
present, at a center hole accepting the bolt ending and tightened by a lock
nut (13). Note because
of the double wall (16) feature of the cap (3), it connects to both, either, a
regular crimped male
flue pipe end or any standard sized opening.
