Description
TITLE OF THE INVENTION
End-wise connection of second chimney components and method therefor FIELD OF THE INVENTION
[0001] The present invention relates to a joint assembly for end-wise connection of two chimney components.
BACKGROUND OF THE INVENTION
End-wise connection of second chimney components and method therefor FIELD OF THE INVENTION
[0001] The present invention relates to a joint assembly for end-wise connection of two chimney components.
BACKGROUND OF THE INVENTION
[0002] Chimney systems permit the exhaust of combustion gases, under positive, negative or neutral pressure, emanating from a variety of appliances including, but not limited to, diesel engine and gas turbine exhausts, industrial oven exhausts, restaurant grease ducts, boilers, incinerators, etc.
(0003] The various components of known factory-built positive pressure chimney systems include lengths, expansion joints, tees, elbows, etc.
These components typically have a flange-to-flange end at there joining point.
These flanges are joined together by aligning the flanges together. They are then joined together by means of a v-shaped assembly band, which is clamped around the flanges of both parts. A sealant is applied in the groove of the v-band before it is clamped to the flanges.

DESCRIPTION OF EMBODIMENTS OF THE INVENTION
DESCRIPTION OF EMBODIMENTS OF THE INVENTION
(0013] Referring to Figure 1, there is shown a joint assembly, generally denoted 10, for connecting two chimney components, identified as A
and B. In the embodiment illustrated, the two chimney components A and B
are two lengths of a double wall chimney construction consisting of an outer wall 12 and an inner wall 14 for chimney component A, and an outer wall 16 and an inner wall 18 for chimney component B.
and B. In the embodiment illustrated, the two chimney components A and B
are two lengths of a double wall chimney construction consisting of an outer wall 12 and an inner wall 14 for chimney component A, and an outer wall 16 and an inner wall 18 for chimney component B.
(0014] The inner wall 14, 18 of each chimney component defines an open end section 20, 22 having a diameter slightly greater than a diameter of the remaining portion of the wall. Each end section 20, 22 has a flanged extremity 24, 26.
(0015] The joint assembly 10 comprises an inner tubular collar 28 having one end 30 insertable in the open section 20 of the chimney component A and an opposite end 32 insertable in the end section 22 of chimney B (as indicated by the arrows 34).
(0016 In the cases of high temperature applications, a tubular band 36 made of ceramic fiber may be circumferentially and exteriorly mounted over part of an outer wall of the collar 28.
(0017 The end-wise connection of chimney component A to chimney component B will now be described. First, the collar 28 is inserted in the end connection 20 of chimney component A. The upper end 30 of the collar is welded, for example seam welded or spot-welded, to the inner wall of the end section 20. When a tubular band 36 is used, it is then inserted between the collar 28 and the end section 20 and is fixed therein by means of an adhesive 40. Subsequently, a sealant 42, such as a silicone, is applied circumferentially on the flanged extremity 26 of the chimney component B.
Chimney component A with the joint assembly 10 is then moved as indicated by arrows 34 to engage the chimney component B.
(0018 Referring to Figure 2, where the two chimney components A
and B are shown engaged to one another, the connection is further secured by means of an assembly band 50,. having a V-shaped mid section 52, to which a pair of attaching bands 54 and 56 are mounted exteriorly. The pair of attaching bands 54 and 56 is welded to the assembly band 50. A silicone material 58 is deposited in the V-shaped section 52 of the assembly band 50. The assembly band 50 and attaching bands 54 and 56 are placed in a manner that the flanged extremities 24, 26 sealed to one another are received within the mid section 52 of the assembly band to which they are further sealed due to the adhesive 58.
[0019] Figure 4 illustrates the construction of the extremities 60 and 62 of an attaching band so that a full ring may be formed.
[0020] Although the present invention has been described hereinabove by way of embodiments thereof, it may be modified, without departing from the nature and teachings of the subject invention as defined in the appended claims.
(0016 In the cases of high temperature applications, a tubular band 36 made of ceramic fiber may be circumferentially and exteriorly mounted over part of an outer wall of the collar 28.
(0017 The end-wise connection of chimney component A to chimney component B will now be described. First, the collar 28 is inserted in the end connection 20 of chimney component A. The upper end 30 of the collar is welded, for example seam welded or spot-welded, to the inner wall of the end section 20. When a tubular band 36 is used, it is then inserted between the collar 28 and the end section 20 and is fixed therein by means of an adhesive 40. Subsequently, a sealant 42, such as a silicone, is applied circumferentially on the flanged extremity 26 of the chimney component B.
Chimney component A with the joint assembly 10 is then moved as indicated by arrows 34 to engage the chimney component B.
(0018 Referring to Figure 2, where the two chimney components A
and B are shown engaged to one another, the connection is further secured by means of an assembly band 50,. having a V-shaped mid section 52, to which a pair of attaching bands 54 and 56 are mounted exteriorly. The pair of attaching bands 54 and 56 is welded to the assembly band 50. A silicone material 58 is deposited in the V-shaped section 52 of the assembly band 50. The assembly band 50 and attaching bands 54 and 56 are placed in a manner that the flanged extremities 24, 26 sealed to one another are received within the mid section 52 of the assembly band to which they are further sealed due to the adhesive 58.
[0019] Figure 4 illustrates the construction of the extremities 60 and 62 of an attaching band so that a full ring may be formed.
[0020] Although the present invention has been described hereinabove by way of embodiments thereof, it may be modified, without departing from the nature and teachings of the subject invention as defined in the appended claims.
