WILLIAM E. VERNON, OF SAN ANGELO, TEXAS.
VENTILATING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 670,443, dated March 26, 1901.
Application filed October 20, 1898. Serial No. 694,123. (No model.To all whom 7t m7ay concern:
Be it known that I, WILLIAM E. VERNON,
a citizen of the United States, residing at San
Angelo, in the county of Tom Green and State
5 of Texas, have invented a new and useful Ven-
tilating Apparatus, of which the following is
a specification.
My invention relates to ventilating appara-
tus, and particularly to a device adapted for
to use in connection with buildings, storehouses,
and school and other buildings, both public
and private; and it consists in the construc-
tion and arrangement of the several parts,
which will be more fully hereinafter described
r5 and claimed.
In the drawings, Figure 1 is a perspective
view of a ventilating apparatus constructed
in accordance with my invention. Fig. 2 is
a detail view showing the hoisting devices
20 used in connection with the ventilating pipe
or shaft. Fig. 3 is a detail view, partly in
section, of one of the sections of the pipe or
shaft. Fig. 4 is a similar view of a section of
a ventilating pipe or shaft, showing a differ-
z5 ent construction of coupling.
Similar numerals of reference indicate cor-
responding parts in all the figures of the draw-
ings.
In the construction illustrated the pipe or
30 shaft 1, which constitutes the conveyer for
air, consists of detachable sections united
by suitable couplings corresponding in size,
whereby the sections are interchangeable.
In practice I prefer to provide each section
35 at one end with an internally-threaded socket
for the reception of the contiguous threaded
extremity of the adjoining section. This
coupling, however, is particularly adapted for
pipe-sections of metal or the equivalent there-
40 of, and when said sections are made of lighter
material, as hereinafter described, an ordi-
nary sleeve-coupling 2, such as that shown in
Fig. 4, may be employed. Also in connection
with the pipe or shaft may be employed a
45 standard 3, provided at intervals with guide
rings or sleeves 4, through which the pipe or
shaft extends, such standard in the construc-
tion illustrated also being sectional, with its
members connected by suitable couplings 5.
50 In connection with the pipe or shaft is a frame
or derrick 6, carrying a windlass 7, which in-
cludes a drum 8, and reeled upon this drumis an elevating - cable 9, extending over a
guide pulley or sheave 10 and terminating in
the clutch 11, adapted for engagement suc- 55
cessively with the sections of the pipe or shaft
as the latter is elevated. It will be under-
stood that I desire to employ a pipe or shaft
of even diameter throughout, and hence in
extending the air-conveyer the sections there- 6o
of must be added successively, the first one
being elevated by the engagement of the
clutch 11 therewith and the reeling of the ca-
ble upon the drum 8, the next section being
attached to the first and the elevating pro- 65
cess repeated until the lower extremity of the
last-named section has reached an elevation
sufficient to allow the application of a third
section, and so on throughout the operation.
At suitable intervals, however, I prefer to in- 70
troduce pipe-sections la, which are provided
with flanges or rings 12, to which are al tached
guy wires or cables 13, said sections 1 being
identical in construction with the other sec-
tions of the pipe, with the exception of said 75
flanges or rings, and being adapted to be in-
troduced at different intervals to suit the con-
ditions under which the ventilating appa-
ratus is to be used or the strains to which
the same will be subjected while in position. 8o
Said guy wires or cables extend from the
flanges or rings 12 to suitable windlasses 14,
arranged at suitable intervals around the
shaft, whereby when the shaft has been ex-
tended to the desired height the strain of the 85
windlasses will tighten the guy wires or ca-
bles, and thus firmly brace the structure.
Obviously during the erection of the shaft
these windlasses 14 are allowed to turn freely
to unwind the guy wires or cables carried 90
thereby.
The pipe or shaft 1 communicates with the
conveyer 15 both directly, as shown at 16,
and indirectly through an air compressor or
reservoir 17, a suitable valve 18 being em- 95
ployed in the direct connection 16 to cut off
such direct communication and cause the air
introduced through the pipe or shaft to pass
into the compressor or reservoir 17 before
finding its way into the conveyer 15. The too
conveyer 15 is separated,and the terminals of
the separated portions are connected to the
opposite ends of a valve-chamber 19 in box
form and having supporting-legs, one of the
