Application filed August 9, 1920, Serial No. 492,487. Renewed February 7, P922. Serial No. 534,814.

T 0 all whom t may concern; Y

Be it known that I, WILLIAM H; lVrLLE'rT, a citizen of the Dominion of Canada, residing at New Richmond Viest, in the county of Bonaventure and Province of Quebec, Canada, have invented certain new and useful improvements in Stovepipes, of which the following is a specification.

This invention relates to the novel construction of the sections of an outer cylindrical casing for stove pipes with intake and outlet air vents. Y

The invention consists in the construction, combination and arrangement of parts asl will be hereinafter -fully described, illustrated in the accompanying drawings, and

pointed out in the claims hereunto appended.

Figure l shows a portion or" the pipe casing partly in section and broken away.

Figure 2 shows one of the brackets 6. Figures 3 and 4 are'details in section of the casing showing' the notched openings.

Referring to the drawing like numerals designate like parts in the various views.

The stove pipe 4 is ot' the ordinary type or of any other particular type which vmight be used in carrying smoke from aA stove or other combustion chamber to a chimney. As is the custom, these pipes are oftencarried through severalV rooms before enteringV the chimney. They often extend through i'loors,r partitions, walls or other portions oicr the building, and on account of overheat in the combustion chamber, the pipe will cause a ire to be Started in the wall or other portions of the building through which it passes. Y v

For overcoming such lires, I provide 'an outer casing 5 which is similar in construe* tion to the stove pipe 4, having one -end of each section telescoped into the end oit the following section to form a continuous length of outer casing. To hold the stove pipe centrally in the casing 5, I provide holding means or brackets which are each formed of a strip Vof metal having the endsriveted or otherwise connected tothe interior oi' the casing 5, so that by the use of a set of two or more of these holding means 6, the pipe 4 is held centrally of the casing5. The brackets '6 are bent inwardly as shown in the ldrawiin many cases the stove pipe is carried through various rooms for heatingpurposes l Vas well as for carrying off the smoke from the the stove pipe 4 and the casing 5 is heated and will suck air in through the openings atV the bent portions 7, while the portions 8 being bent inwardly forces the air outwardly and by' this means I keep a circulation of air passing from the room through the openings at the ent portions 7 striking the Vstove pipev 4, and being carried back into the room through the openings at thebent portions 8, which will be most efficient in keeping the circulation of air between the pipe 4 and the casing 5 cool as wellfas providing the means for heating the rooms stove pipe passes.

explanation' has been omitted. f

What I claim as new is: 1. A cylindrical casing adapted to enclose a stove pipe, and having portions bent outwardly and portions bent inwardly to form notched inlets and outlets, and brackets inside said casing disposed-opposite said inwardly bent portions to hold a stove pipe centrallyrwithin said casing and to'provide through which they vi .80. 51 From the foregoing itV is ythoughtuth'at the Vconstruction of my invention will be clearlyk 1 understood and, therefore, aV more extended i.
