This invention relates to ventilators and par
' ticularly to ventilators adapted to be disposed
over an opening along the ridge of a roof. Ven
tilators of this general type are disclosed in
ranged at the ridge of the roof, or at any other
suitable point. It comprises as its principal ele

same dimensions as the opening in the roof, and

ventilator units.
This feature obviates the ne
cessity, in many instances, of making the venti
lators to order in accordance with the length
dimensions of a speci?c building.
Moreover, this feature of the invention makes
it possible for the user to add one or more stand
ard length ventilator units to those already in
use, where, for example, the building is put to
a use requiring greater ventilation.
_ In accordance with another feature of the in
vention, the structural strength of ventilators of
this type is materially increased, while at the
same time the manufacture and assembly of the

The lower edges 20 of the storm bands l2 are
spaced from the eduction pipe 6. Along the up
per longitudinal edges of the eduction pipe 6 are
provided the lips [6 which extend outwardly sub
stantially as far as the edges 20 of the storm
25 bands l2, these lips having slight downward in
clinations.
Spaced along the ventilator are a number of
transverse ba?les generally indicated by the ref
erence numeral l4. These have their upper edges
28 located higher than the upper edges 18 of the
storm bands, and extend downwardly to the cap
8. When air flows transversely of the ventilator
or perpendicular to the length thereof these
baffles have no effect. However, whenever the

desired, with dampers (not shown) of the type
of inwardly projecting angle members 50 for
joining the end walls to the storm band [2 (see
Figures 4 and 5). Moreover, the end walls are
provided with angle support means 52 for the
indicated in U. S. Patent No. 2,232,027, to which
reference has already been made.
The ventilator, as described thus far, is sim
ilar to the ventilator disclosed in said U. S. Pat 5 ends of the cap 8, and also an inwardly project
ing vertical member 54 for the end of the di
ent No. 2,232,027. The improvements provided
by the present invention reside primarily in the
particular shape and manner of construction of
the parts and their assembly.
As shown in Figure 1, two ventilator sections
A and B are suitably joined together by means
which will be described hereinafter, the arr-ange
ment being such that ventilator sections of
standard lengths may be made, which sections
may be joined together in su?icient numbers
when placed on a building roof to meet any de
sired ventilating requirements.

the eduction pipe 6 is made up of two longitudi
nal members 6a and 6b, each having a down
wardly ?aring ?ashing portion 1 adapted in use
to be supported by the roof 4 adjacent the roof
opening 2. The members 8a and 6b constitut
ing the eduction pipe 5 may be stamped from
vider l5. Brace members 56, to which the ends
of the walls of the eduction pipe are secured, are
also provided. The members 58, 52, 54 and 55
may be of heavier material and may be secured
to the end walls 24 by spot welding or the like.
The tops 22 of the end walls 24 extend up
wardly to a distance corresponding to the upper
edges of the ba?le pieces Ma, MI), and like them
are also turned over to avoid any sharp protrud—
ing edge. The bottom edges 53 of the end walls
24 are cut with an inverted V to correspond to
the angle of pitch of the roof.
In disposing a ventilator section on a roof, it
is advantageous to provide end ?ashing mem
bers 68 which, as shown in Figure 5, may be cut
and stamped from one piece of sheet metal in
such manner as to provide two upstanding pieces
62 and, 64, between which the lower edge 58 of
an end wall 24 is disposed when the ventilator
section is positioned on a roof. Where only one

The embodiment of Figure 6 is generally simi 15 prising clip members adapted to be disposed over

plane of the ba?le pieces Ma, [41), two brace
members 14 of sheet metal‘ provided with pro
jecting angle portions 18. It will‘ be seen from
the drawings that these angle portions are adapt
ed to be rigidly secured to the storm band l2 near
the bottom edge by securing means 19. The
brace members ‘[4 also are rigidly secured to their
adjacent baille pieces either [4a or Mb by secur
ing means 8|.
The brace members 14 are also
rigidly anchored to the sheet metal bracing mem
ber 38 by means 83. In this embodiment, the
brace members 14 take the place of angle mem
bers 45 in the other embodiment.
It will be noted that in both embodiments dis
closed, substantially all of the parts may be sim
ply cut and stamped from sheet metal, and that
the various parts may be readily assembled with
the minimum of eilort or skill,
Still further it will be apparent that the inven- .
tion avoids the necessity of an angle bar sup
porting framework such as disclosed in the pat
ent referred to above. In accomplishing this end
the baflie pieces themselves, together with other
sheet metal pieces disposed in the same plane, are i;
so shaped as to support the storm band in proper
relationship to the walls of the eduction pipe and
other elements.
As previously mentioned, the invention also
makes it possible to construct ventilators in
standard length units which may be joined to
one another if necessary to meet speci?c venti
lation requirements.
It should be obvious that changes in the con
struction and disposition of the parts may be
made within the scope of the invention as dis
closed.
