D. O. MALAFOURIS TELESGOPING CHIMNEY FLUE ASSEMBLY March 14, 1967 Filed May 28, 1965 Dannie OMQIQ Four-1's INVENTOR BY United States Patent Ofifice 3,308,808 TELESCOPING CHIMNEY FLUE ASSEMBLY Dannie O. Malafouris, 7945 NE. Alberta St., Portland, Oreg. 97218 Filed May 28, 1965, Ser. No. 459,662 6 Claims. (Cl. 126314) This invention relates to a telescoping chimney flue assembly for use in routing a stove pipe into a chimney flue.
It is the general object of the present invention to provide a telescoping chimney flue assembly which is useful in routing a stove pipe leading fromv a stove or fireplace through a wall or ceiling and into the chimney flue, which assembly is suitable for use with stove pipes of varying length and cross section and which is so constructed as to conceal oran'mentally the opening through which the stove pipe and flue pass.
In the drawings:
FIG. 1 is an exploded view illustrating the parts of the hereindescribed telescoping chimney flue assembly in their separated relation;
FIG. 2 is a detail view in side elevation, partly in section, of the hereindescribed assembly; and
FIG. 3 is a perspective view of a support plate used in conjunction with the assembly.
The telescoping chimney flue assembly of my invention broadly comprises a support plate which fastens to a structural member, a started flue pipe section releasably engaging and supported by the plate, a stove pipe, and an escutcheon plate mounted on the starter flue pipe section and and overyling the opening through which the stove pipe and flue pipe pass.
Referring particularly to FIG. 3, the support plate indicated generally at 10, comprises: A flat support section 11 having a central opening dimensioned to receive the flue pipe section; a shield section 12 parallel to the support section, but spaced from it and extending outwardly; a connecting section 14 connecting the support and shield sections and arranged substantially perpendicular to the planes of the latter; and an upstanding rim 16 extending upwardly from the outer edge of shield section 12.
Fastening tabs 18 are provided with screw or nail holes and extend upwardly from connecting section 14 at suitable intervals, for example at intervals of 90. Support plate is dimensioned for insertion in an opening in ceiling or wall 20 adjacent the stove or other heating unit. Securing tabs 18 are nailed or screwed to joists or other supports 22.
The opening through support plate 10 receives a starter flue pipe section, indicated generally at 24 which, with companion sections not illustrated, form the flue leading from the stove pipe to the chimney.
The starter flue pipe section comprises an outer pipe 26 concentric with an inner pipe 28. The space between the pipes is filled with asbestos or other packing.
The diameter of the flue pipe section is somewhat less than the diameter of the opening through support plate 10. However, the flue pipe section is provided with an annular exterior rib 32 having a diameter such that it engages and bears against support section 11 of the plate, thereby supporting the starter section as well as the remaining superimposed, communicating, flue pipe sections.
The inner end of flue pipe section 24 is formed with an annular head 34 of somewhat smaller diameter than the diameter of rib 32 and which accordingly will pass through the opening in the support plate.
A length of stove pipe 36 is received in the bore of flue pipe section 24 in telescoping, adjustable arrangement. The stove pipe may be of constant diameter along 3,308,808 Patented Mar. 14, 1967 its length or, as frequently is necessary, may comprise two sections 38, 40 of different diameter interconnected by a reducer section 42.
The lower end of the stove pipe connects to the stove or fireplace opening. The upper end telescopes into the interior of flue pipe 24. It may be adjusted between the full line and dash line positions of FIG. 2, as required for installation and use. A single stove pipe thus may -be employed without diflicult alteration in a variety of different installation situations.
An escutcheon plate, indicated generally at 44, is provided to conceal the opening and exposed parts of the flue assembly. This lends an ornamental feature to the assembly since, in addition to concealing unsightly parts, the escutcheon plate may be enameled in a color matching the stove or fireplace, or provided with ornamental designs.
The escutcheon plate is provided with a central opening dimensioned to receive the upper end of stove pipe 36. It also is provided with means for releasably securing it to the inner end of starter pipe section 24. Such means are shown particularly in FIG. 2.
A flange 46 having an annular recess around its inner margin is secured to the inner surface of escutcheon plate 44, concentrically with the opening theret hrough. It is held in place by suitable securing means, such as bolts 48. The recess in flange 46 is dimensioned to receive in snap-fit engagement head 34 on the inner end of starter pipe section 24.
To mount the assembly, support plate 10 is secured across the flue opening through ceiling 20 by inserting it in the opening and nailing tabs 18 to joists 22. Starter flue section 24 then is slipped into the opening through the plate until rib 32 abuts against support section 11 of the plate. The remaining flue sections then are stacked on the starter section and connected to the chimney in known manner.
Escutcheon plate 44 is secured in place 'by snapping recess flange 46 over bead 34 on the lower margin of flue section 24. Stove pipe 36 is passed through the opening in ornamental escutcheon plate 44 and telescoped into the bore of flue section 24. Stove pipes of varying length and type thus universally may be accommodated in a single flue assembly, without trimming them, shaping them, specially, or altering them in any way. It accordingly will be seen that there is provided an assembly in which the several objects of this invention are achieved and which is well adapted for the conditions of practical use.
It is to be understood that the form of my invention herein shown and described is to be taken as a preferred example of the same and that various changes in the shape, size and arrangement of parts maybe resorted to without departing from the spirit of my invention or the scope of the subjoined claims.
Having thus described my invention, I claim:

('b) means for fastening the support plate to a structural member,
(c) a starter flue pipe sect-ion insertable through the opening in the support plate substantially normal to the plane thereof, the flue pipe section having a bore of substantially uniform cross section,

5. A telescoping chimney flue assembly comprising (a) a support plate having a central opening,
(b) means for fastening the support plate to a structural member,
(c) a starter flue pipe section insertable through the opening in the support plate substantially normal to the plane thereof,
