ROBERT IT. SChUMACHER, OF NAVASOTA, TEXAS.
VENTILATOR.
SPECIFICATION forming part of Letters Patent No. 644,335, dated February 27, 1900.
Application filed November 15, 1898, Serial No. 696,551. (No model.)To all whom it imay concern:
Be it known that I,ROBERT H. SCHUMACHER,
a citizen of the United States, residing at
Navasota, in the county of Grimes and State
5 of Texas, have invented a new and useful
Ventilator, of which the following is a speci-
fication.
This invention relates to ventilators de-
signed to be applied to the roofs of buildings
to and other structures to provide means for in-
suring a proper ventilation of one or more
rooms throughout the building by providing
for maintaining a constant circulation of
fresh or cold air into the building and an es-
15 cape for the heated and vitiated air.
To this end the invention contemplates an
improved construction of house - ventilator
having simple and efficient means for forcing
a large volume of air into a house or build-
20 ing, so that it can be distributed throughout
the various rooms or apartments thereof,
while also insuring the proper exhaust or out-
let for the heated and vitiated air,.thereby
causing a continuous circulation of the air.
25 In carrying out this object the invention pro-
vides a novel form of hood or cap for the ven-
tilator which will automatically adjust itself
in the direction of the wind in the manner of
a weather-cock and will also provide for a
30 forced downdraft of the cold or fresh air.
Another feature of this invention is u-
proved means for effectively excluding the
rain from the inlet and exhaust passages of
the ventilator.
35 With these and other objects in view, which
will readily appear as the nature of the in-
vention is better understood, the same con-
sists in the novel construction, combination,
and arrangement of parts hereinafter more
40 fully described, illustrated, and claimed.
While the essential and characteristic fea-
tures of the invention are necessarily suscepti-
ble to modification, still the preferred embodi-
ment of the invention is illustrated in the ac-
45 companying drawings, in which--
Figure 1 is a vertical longitudinal sectional
view of a house-ventilator constructed in ac-
cordance with the present invention. Fig. 2
is a cross-sectional view on the line 2 2 of
5o Fig. 1. Fig. 3 is a similar view on the line
3 3 of Fig. 1. Fig. 4 is a similar view on the
line 4 4 of Fig. 1. Fig. 5 is an enlarged de-tail sectional view of the ball-bearing support
for the revoluble elbow-hood.
Referring to the accompanying drawings, 55
the numeral l designates a stationary upright
cold-air trunk, which is preferably made in a
cylindrical form and is designed to be sup-
ported on the roof of a house or building by
any of the well-known means, and in the pres- 6o
ent invention the said cold-air trunk 1 forms a
downdraft-flue for the passage of cold or fresh
air which is to be circulated into the building.
To provide for conducting the cold air into
the house or building to be ventilated, the 65
cold-air trunk 1 has projected from its lower
end 2 a supply-pipe 3, which when only a sin-
gle room or apartment is to be ventilated is
designed to have coupled thereto a single ven-
tilating-pipe of the same diameter; but ordi- 70
narily the ventilator is designed to supply a
number of rooms with fresh air, and to carry
out this object the bottom pipe extension 3
of the cold-air trunk is provided -with an end
plate 4, closing its lower end and having fit- 75
ted thereto the upper ends of a plurality of
distributing - tubes 5, which are carried
through the walls or in any other desirable
way into the different rooms, so that each
room will have a separate and independent 8o
supply-pipe connection with the main cold-
air trunk of the ventilator.
The upright cold-air trunk 1 has projected
from the upper end thereof a reduced sup-
porting-neck 6, which provides for the sup- 85
port of the revoluble elbow-hood 7 of the ven-
tilator. The vertical or pendent portion of
the revoluble elbow-hood 7 loosely encircles
the neck extension 6 of the trunk and is pro-
vided at its lower edge with a horizontal bear- 90
ing flange or plate 8, which loosely bears on
top of a series of bearing-balls 9 or similar
antifriction - bearings, which are preferably
made of vitreous or other equivalent material
which will not corrode under the action of 95
the weather. The balls or antifriction-bear-
ings 9, which provide a loose antifriction-sup-
port for the lower end of the hood 7, are
loosely housed within a bearing-cup 10, fitted
to the neck extension 6 and encircling the ex- 100
terror portion thereof. In addition to carry-
ing the ball-bearings or equivalent support
for the revoluble hood 7 the neck extension 6
is further provided near its upper end with
