THOMAS J. GOODWIN, OF LAMPASAS, TEXAS.
VENTILATOR-FLUE.
SPECIFICATION forming part of Letters Patent No. 700,762, dated May 27, 1902.
Application filed July 26, 1901. Serial No. 69,800. (No model.)To all whom it may t concerm:
Be it known that I, THOMAS J..GooDWIN, a
citizen of the United States, residing at Lam-
pasas, in the county of Lampasas and State
5 of Texas, have invented a new and useful
Flue, of which the following is a specification.
This invention relates to flues for general
use, and has for its object the production of
a flue constructed of detachable parts that,
io dismembered, will "nest " or pack one with-
in the other, so as to occupy less space while
being shipped.
The invention is capable of being applied
to any form-of sheet-metal flue, and for the
15 purpose of illustration I have shown it in the
drawings applied to an approved form of flue.
Figure 1 represents a side elevation of the.
device complete. Fig._ 2 is a sectional ele-
vation. Figs. 3 and 4 are perspective views
20 of sections of parts of the casings, illustrating
the manner of""nesting" or packing them.
Fig. 5 shows enlarged sectional details of the
detachable fastenings or couplings.
The flue employed for illustration shows an
25 outer casing formed in two main sections 1
and 2, one of each section formed with one-
edge folded over, as at 3, and thence folded
back again upon the first fold, as at 4, the
latter fold forming a socket adapted to re-
30 ceive the opposite unfolded edge 5 of the other
section, as shown in Fig. 5, which represents
the two folds and embraced unfolded edges
of a pair of sections. -By this means the two
sections when combined form a completed
35 cylinder with overlapping joints. To "lock "
the sections thus united, small clips 5 are
attached to the unfolded edges 5 of the sec-
tions and adapted to pass through apertures
7:, formed through the bottom of the folds 4,
40 and be bent back over the folds, as shown in
Figs. 1, 2, and 5. By this means the two sec-
tions are securely "locked" together while
at the same time are easily detachable by
simply bending the outer ends of the clips
45 backward until they are in alinement with
the sections 1 and 2,again, as shown at. the
lower part of Fig. 1, when the two sections
may be easily disconnected.
The flue shown is of the double style, con-
50 sisting of an outer shell formed of the sections
1 and 2 and an inner shell formed of similar
but smaller sections 7 and 8, having the folded-over edges and the locking-clips of the same
construction as in the sections 1 and 2. As
all the folded-over edges and the clip-fasten- 55
ings are the same in all the various parts,
they are denoted by like letters of reference
throughout the drawings. The two sections
are connected at their lower edges to annular
perforated collar or socket 9, having an air- 6o
chamber between the two sections, through
which the air will freely pass. The upper
edges of the two main sections are coupled
by an annular perforated ring or collar 10, the
outer edge of the collar being turned down- 65
ward outside the outer section 1 and 2, as at
11, and the inner edge turned downward in-
side the inner section 7 and 8, as shown at 12
in Fig. 2. Attached to the inner section 7 and
8 are small clips 13 and 14, adapted to project 70
through apertures in the collar 10 and be bent
outward over the. collar, and thus form a
means for detachably locking the collar to the
sections, and similar clips 15 and 16 will be
attached to the lower edge of. the inner sec- 75
tion 7 and 8 and adapted to pass through ap-
ertures in the collar 9 and be bent over the
collar to form a means for detachably con-
necting the collar to the sections. Surround-
ing the outer section 1 and 2is a roof-shield 8o
17 of the usual form, which will be slidable
upon the sections and inclined to conform to
the ."pitch" of the roof through which the
.flue projects. Connected. removably to the
upper end of the main flue-sections is an ex- 85
tension-flue, and above this extension-flue is
a cap or rain-shield for the extension, and
between the extension-flue and the main flue
is a rain-shield collar.
The extension-flue consists of two semicy- 90
lindrical sections 18 and 19,having the turned-
over edges 3 and 4 and clips 6, which are
passed through corresponding slots or aper-
tures 7b, the same as the sections 1 2 and 7 8,
as shown in Fig. 3, which represents these 95
two sections 18 and 19 detached and placed
in position to be "nested" or packed for ship-
*ment.
20 is a short coupling-section secured to the
sections 18 and 19 and adapted to be inserted z o
into the upper end of the section 7 and 8, with a
rib 21 rolled therein to limit its downward
movement and also provided with one or more
ribs rolled into it, as at 22, to support a con-
