3 claims. (Cl. ie-c2 The present invention relates to an insulat ed chimney and has to do with .a chimneycon- .struction of such character that the chimneI may be `erected next to framework of buildings without any fear of nre hazard.v l
The present invention is'u-scilllin connection with the erection of housing .projects wherein minimum cost and efliciency'are necessary, although it is adaptable for use on any kind of building construction.
An object of the present invention is to provide an insulated metal chimney having means `for maintaining the exterior oi the chimney at temperatures below the ignition points of usual building materials.
The chimney construction of the present invention is shown as a sectional chimney, the sections comprising inner and outer metallic tubes with the space between them filled by finely ground heat insulating material.
The objects of the present invention will be apparent -from the following description and accompanying drawing.
The accompanying drawing illustrates a chimney construction of the present invention and the views are as follows.
Fig. 1 is a vertical sectional view through a chimney;
Fig. 2 is an enlarged cross sectional view taken in the plane of line 2--2 of Fig. 1; and
Fig. 3 is an enlarged fragmental View of a joint between the sections of the chimney.
The drawing will now be explained.
The chimney shown in Fig. 1 includes a plurality of sections arranged one on top of another and comprising a lower section 5 and a plurality of upper similar sections 6.
The section 6 includes an inner liner of vitriiied enameled metal having at its upper end a socket 'l to receive the lower end of an adjacent upper section in nested relation. The inner liner is designated 9.
Spaced from the liner 9 is an outer casing member IB to provide an annular space between the casings 9 and i0. This space is lled with powdered insulating material such as aluminum silicate, designated as Il, which I have found to be a very excellent heat insulator.
In order to prevent the powdered material from escaping between the spaces 9 and ill, plugs are inserted at each end of the section. The plugs I2 are annular members made of powdered aluminum silicate and a suitable binder so that when the plugs are inserted in place at the ends 2 of the sections, .the .powdered insulating material l l .is .preventedfr'om escaping..
Referring .to Fig. 3, it will lbe' noted that angle flanges? l .3.. are secured to thelower vends of the inner.casings 9 toextend intothe space. between thefrcasings .9, and il), and that the .outer margins lof `'the outer casings .lil are indented as at Il. The plugs l2 are heldin place by the angle members I3 and the indentations i4.
The lowermost section 5 has a closed lower end and a lateral take-off i5 to which the pipe from a heater is connected.
The lower section 5 comprises an inner casing member I5 and an outer casing member, both of which are formed to the particular shape desired, and the spaces between these sections are lled by insulating material l held in place by a plug l2 at the upper end of the section, and a similar plug l2 at the end of the take-01T section I5.
Communicating with the lower end of the nuethat is, with the space within the inner casing 9, is a drain pipe il which may be connected to a sewer to draw off any condensation that may accumulate in the lower end of the chimney.
The chimney is erected by piling sections one on top of another to the desired height.
Tests of the chimney construction of the present invention have shown a maximum temperature on the outside of the casing l0 of 195 F., with a stack temperature of 1000 F.
The ignition point of certain building materials, a-s supplied by the National Fire Products Association, discloses the following:
White pine 406 Long leaf pine 428 Cedar 370 The Bureau of Standards gives the ignition point of Yellow Pine as 496 F.
It will therefore be readily observed that the chimney construtcion of the present invention makes possible the erection of a sectional chimney of more than adequate protection against nre hazard, so that a chimney of the present invention may be erected in contact with frame building material.
In connection with the test above mentioned, it may be noted that the temperature in the heater was 1500 and the heater was placed 36 inches away from the chimney.
The invention has been described herein more or less precisely as to details, yet it is to be understood that the invention is not to be limited thereby, as change-s may be made in the arrange-` ment and proportion of parts, and equivalents may be substituted Without departing from the spirit and scope of the invention.
The invention is -claimed as follows:
1. A sectionalized chimney comprising a plurality of sections, every section having a vitried metallic ue casing and an outer metal` lic casing. spaced from. the fiue,.and a lling of finely -ground aluminum silicate lling the space between the casings, and end plugs comprising rings of aluminum silicate and a binder fori preventing escape of the powdered insulating material. 'Y
2. A sectionalized chimney comprisingalplurality of sections, every section having'a vitried enamel coated metallic iiuer casing-andan outer f metallic casing spaced from the flue, andalling of fine particles of insulating material such as aluminum silicate filling the 'space betweenthe casings, and end plugs comprising rings/of refractory material and a -binder forV preventing escape ofthe powdered insulating material.
3. VA bottom sectionior a secti'onalized chimney comprising anouterfcasing .of generally cylindri` cal form with a closed lbottom and a lateral flange,` an inner sectionof the same general sectional outline but of less dimension in diameter and length arranged within the -outer section, said inner section having a lateral flange within and spaced from the lateral ange of the outer casing, the space between said casings and the ilanges being lled with fine particles of insulating material such as aluminum silicate with the material at the lower end of the closed bottom of theinner section between it.k ,and .the lower bottom of the outer section, Aand ring plugs closing the spa-ce between the casings at the upper end thereof and the space about the ends of the ilanges.
