' I Gttotneg Patented Aug. 7, 1945 UNITED STATES PATENT O-FFI-CE I QHIlVlNEYLlNER EXTENSION Lester H. Munyon, Spokane, Wash. Application July 27, 1944, Serial No;"546,789
1 Claim. (cl. 'za-ssl This inventionrelates to an extension for-a chimney liner and it is one object of, the invention to provide'a device of this character formed of sheet metal and of such construction that it may be applied to a protruding portion of a liner and firmly secured in upright position.
Another object'ofthe invention is to provide an extension having a. slip joint extending longitudinally of one wall, the interfitting portions of the metal sheet from which the extension is formed being, pivotally connected at theupper end of the joint so that the lowerportion of the extension may be expanded or contracted and applied'to the protruding end portion of the chimneghli'ner in frictional gripping'engagement there- Another object 'of the invention is to provide a joint formed by folding aside edge portion of the metal sheetfrom which the extension is formed and of such formation that while the lower, portion of theextension may be expanded and contracted, leakage be likely.
Another object is to provide the extension with means at its lower end'for effecting tight binding grip between the extension and the chimney flu liner to which it is applied.
' I The extension is formed from a rectangular sheet of metal of suitable length and width, bent to form a tubular. extension 3 having opposed side walls, One of which is indicated by the numeral 4 and is formed intern'i'ediatev its width with a slip joint 5 extending thefull height or length of .the'extension. This joint is shown on an enlarged scale in Fig. 5, and, referring to this figure, it will be seen that a side edge portion of the metal sheet is folded back and forth upon itself to form a pocket 6 open along its outer side edge and of air through the joint will not' I Another object is to provide the extension-with 3 members for resting upon the upper endof a chimney'liner and provide a good support for the extension whensaid extension is .fittedwithin the liner.
Intheaccompanyingdrawing: Fig. 1 is a perspective view showing the improved extension applied -to a protruding upper end portion of a chimney liner and tightly clamped about the liner. I
Fig. 3 is a perspective'view showing an exten having inner and ,outer walls 1 and 8. The other side edge portion of the metal sheet fits within the pocket 6 and, at its upper end is secured by a rivet 9 which serves as a pivot pin and permits the interfitting portions of the wall 4 to have swinging adjustment transversely of the wall and its joint. Therefore, when the extension is applied to the liner, 'the lower end of the'extension may be expanded and fitted about the protruding portionof the liner and have snug fitting engagement therewith, or the lower end of the extension may be thrust into the liner and then ex.- panded for close fitting contact with walls ofthe liner.
When the extension is fitted about the liner, it must be constricted into tight frictional binding engagement with the liner, and to do so there have been provided clamps I 0, each of which consists of brackets ll fixedly secured against..-the wall 4 with the joint 5 disposed between the brackets. These brackets have ears|2 projecting latsion mounted within the protruding upper end portionof a chimney liner.
Fig. 4 is a sectional view on the line l.-.4 of Fl8.3. v
Fig. 5 is .a' sectional view, on an enlarged scale, taken transversely through the upper end of the slip joint.
This improved-extension is intended to be appliedto the liner l of a chimney and,- when it is applied, it has frictional gripping engagement with the portion of the liner which protrudes from the top of the chimney. It may fit about the protrudingportionof the liner, as shown in Figs. 1 and 2, or fit. within the liner, as shown in P ies. 3 and 4. l
erally from the wall t and formed with openings to receivea bolt l3 which'has its head engaging the outer side face of the ear of one bracket and its nut I4 bearing against the outer side face of the ear of the-other bracket. When the nut is tightened the brackets are drawn toward each other and the lower end of the extension will be.
contracted into tight binding engagement with the liner.
When the extension is. to be fitted within the liner instead of about the same, a single set of brackets l5 are secured to the wall 4 at opposite sides of thelower portion of-the joint; The flanges l6 arebraced by horizontal webs l1 and th bolt l8 passes through openings in the ears;'w1 h its head engaging the outer side face of one ear. Two nuts 19 are carried by the bolt l8 and engage confronting side faces of the cars, so that, by turning the nuts, the brackets may be shifted away from each other and the lower end of the extension expanded into tight binding engagementfiwitli walls of the liner. Strips of angle metal 20 are secured horizontally againstfsrde walls of the extension in the plane of the brackets l5 and the horizontal flanges of the strips 20, and the brackets serve to contact the upper ends of walls of the liner and limit downward movement of the extension into the liner. Therefore, the extension will be supported when applied to the liner and prevented from slipping downwardly into the liner beyond the position shown in Fig. 3.
In both embodiments of the invention illustrated and described, the extension may be expanded and contracted at its lower end when applied to the liner and held in tight frictional binding engagement with walls of the liner. The fact that the interfltting portions of the wall 4 are pivotally secured at the upper end of the slip joint 5, retains these portions in overlapping engagement with each other and eliminates an open crevice through which air could pass and interfere with efficient drawing of the chimney.
Having thus described the invention, what is.
claimed is:
brackets carried by said wall'at opposite sides of An expansible and contractible extension for a chimney flue liner comprising a sheet of metal ing a side edge portion of the sheet metal, back and forth to form a pocket open along its outer side and fitting the other side edge portion of said sheet metal into the pocket, a pin passing through the upper ends or the interfltting portions of th sheet metal and pivotally connecting same,
said joint and having ears projecting laterally from the tube, and a bolt passing through said ears and carrying nuts abutting confronting side faces of the ears to expand the tube for tight fit within a chimney flue liner, and cleats projecting laterally irom the tube cooperating with the brackets for resting upon the upper ends of the flue liner and supporting the tube in the liner.
