MICHAEL H. SHANLEY, OF GRANBURY, TEXAS.
VENTILATOR.
S1PECIFiCAT ONIT forming part of Letters Patent No. 340,829, dated April 27, 1886.
Application filed February 5, 18E6. Selial No. 193,163. (No model.)To Call Wzon it Many concerz':
Be it known that I, MICIIaEL H. SHANLEY,
a citizen of the United States of America, re-
siding at Granbury, in the county of Hood
5 and State of Texas, have invented certain new
and useful Improvements in Ventilators; and
I do hereby declare the following to be a
full, clear, and exact description of the in-
vention, such as will enable others skilled in
to the art to which it appertains to make and use
the same, reference being had to the accom-
panying drawings, and to letters or figures of
reference inarked thereon, which form a part
of this specification.
15 My invention relates to certain new and use-
ful improvements in combined flues and ven-
tilators; and it consists in the construction
and combination of the parts, as will be here-
inafter fully set forth, and specifically pointed
20 out in the claims.
In the accompanying drawings, which illus-
trate my invention, Figure 1 is a side view of
a combined flue and ventilator constructed in
accordance with my invention. Fig. 2 is' a
25 vertical section. Fig. 3 is a transverse sec-
tion taken through the line x x of Fig. 2.
Fig. 4 is a detail perspective view.
My improved flue and ventilator is applied
to the roof of a building, and extends through
30 the same to the apartment which it is desired
to ventilate, so that the same can be employed
during the winter months as a smoke-exit pas-
sage and during the summer as a ventilator-
passage compartment.
35 A refers to the outer casing, which extends
through the roof and above the same, and
downward into the compartment. This outer
casing is provided centrally with a flue, B,
which extends from the compartment or room,
40 preferably near the ceiling, to a suitable dis-
tance above the roof, and a transverse cover-
plate, b, is secured to the outer casing, A, and
through a central opening therein the central
flue, B, passes. Above the plate B, to the cas-
45 ing A, is attached a suitable cap, C, of orna-
mental configuration, which is provided, near
its upper part, with a cover portion, C', be-
tween which and the lower portion, C, is a
space,ithroughlwhiehimpure airfrom the apart-
50 ment may pass in summer or smoke in winter.
Thelower portion of the cap C has near its base
a series of perforations, c, through which airmay pass, so as to create an upward draft
above the flue through the exit-opening be-
neath the cover-plate C'. 55
The space D, between the central flue, B,
and the outer wall or casing, may, if desira-
ble, be formed in two independent compart-
ments, or may consist of a single compart-
ment, as desired. 6o
The outer casing, A, near its upper end, is
provided on its four sides with shields or
screens 4, and beneath the same are located
openings E, said screens or curved plates d
being located above said openings, so as to 65
prevent rain or snow entering therein. Be-
neath the openings E the outer casing, A, is
provided with hinges e, one of the leaves of
said hinges being secured thereto, while the
opposite leaf is attached to the under side of 70
the funnels F, said funnels being fully illus-
trated in Fig. 4 of the accompanying draw-
lugs. The funnels have attached near their
inner ends staples f, to which flexible con-
nections are secured, said flexible connections 75
extending therefrom downwardly through the
compartment 1) and into the chamber, the low-
er ends being provided with rings or knobs.
If desirable, the compartment D may have
located therein tubes G, through which the 8o
flexible connections or cords g will pass, these
tunles also serving as conduits for the air from
the interior of the building, and these tubes,
when desired, may extend under the outer
coinpartmen:, A, to suitable points within the 85
room. When the tubes G are not employed,
the outer casing, A, has perforations, through
which the air may pass.
When it is desired to ventilate a compart-
ment, the operation of mlly invention is as fol- 90
lows: The stove-pipe from the heating appa-
ratus is connected to the central tube, B,which
forms the smoke-exit passage, and when i t
desired to have air in the room for ventilating
purposes the funnel on the side from which 95
the wind is blowing is raised and held in an
elevated position by drawing upon and secur-
ing the flexible connection y, which causes the
air to enter the tube through which the flexi-
ble connection passes into the room. The fun- ioo
nels are of sufficient weight to drdp automatic-
ally, and are raised and held in a raised po-
sition by the flexible connections hereinbefore
described.
