' (01. 98-42)‘ v 2 1 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 ments, an eduction pipe 6 of substantially the same dimensions as the opening in the roof, and United States Patent to Edward R. Gunter, No. 2,232,027, dated February 18, 1941, and the pres ent invention, although possessing features of which preferably is an elongated rectangle in broader application presents speci?c improve ballle plates l4, and lips 16.. cross section, a cap member 8, a divider l0 form¢ ing a part of the cap member, storm bands l2, As will be apparent from the drawings, the cap ments for the ventilator structure there illus trated and described. 10 member‘ 8 and divider l0 form a cover for the eduction pipe 6 so as to prevent water from falling _ One object of the present invention is to in vertically thereinto.

They extend inwardly su?icient more general application, for example, by making the ventilator in sections of standard lengths and 15 1y far at the upper ends, as indicated at I8, to cross straight lines drawn through the upper by providing means whereby sections maybe edges of the eduction pipe and the outer edges added to one another so that the ventilator re of the cap so that the direct entrance of rain quirements for buildings having di?erent roof into the eduction pipe from the sides is prevented. lengths can be taken care of by standard length 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 20 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 parts is greatly simpli?ed. The invention con templates the elimination of an angle iron frame work and the replacement thereof by sheet metal 35 air flows at an angle, or even longitudinally of the ventilator, the ba?les l4, particularly since parts which may be readily cut, stamped, and they extend above the storm bands, provide a assembled.

The end walls 24 of the ventilator also extend upwardly as high as the baffles, so as to provide additional obstacles.

As shown in some of the ?gures, the ventilator when in operative po is intended to be applied over an elongated rec sition may be provided with a covering screen 26. tangular opening 2 in a roof ,4. It may be ar Still further,- the ventilator may be provided, if 2,404,961 3 4 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 individual parts of a section are perhaps more clearly shown in the exploded view (Fig ure 5). From this ?gure it will be apparent that I 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 ventilator section is required, such a ?ashing member 60 will be provided for each end wall 24. As previously indicated, the invention contem sheet metal or the like. The cap member 8 may also be cut and stamped from one piece of sheet metal and then bent or folded to provide the divided I9 as shown. 30 plates the use of a plurality of ventilator sec tions such as A and B when requirements de In the embodiment illustrated in Figures 1 to mand, or where, for example, it is found neces 5, the ba?les, generally indicated by the refer~ sary to add an additional section to one already ence numeral Ill, are shown as made of two installed and in use.

This is accomplished by further, it is readily ascertained that their shape or design prevents the occurrence of capillary action, an action which ordinarily results when two perfectly ?at pieces of metal are lapped and placed where moisture in the nature of rain or the angle members 46, one end of which is so snow might reach them. cured to the eduction pipe wall and the other to It should be apparent that when two ventilator the storm band.

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. ‘ I claim: 1.
