Kenneth M. Parsons, Coopersville, Michqassignor to Air Control Products, Inc., Coopersville, Mich" a corporation of Michigan Application July 24,1950, Serial No. 175,619 s This invention relates to improvements in roof ventilators adapted for installation on slant roofs. v
The main objects of thisinvention are:
First, to provide a roof ventilator which may be installed on a slant roof in which there are few Claims. (01-. 98-42) parts and they are so formed and assembled as v to provide effective joints between them and at the same time are simple to produce andvery easily assembled.
Second, to provide a structure having these advantages in which the parts may be very economically produced and formed 'of light sheet stock, and at the same time, the structure is relatively rigid and not likely to be distorted in handling or installing.
Objects relating to details and economies of the invention will appear from the description to follow. The invention is pointed out in the claims.
A preferred embodiment of the invention is illustrated in the accompanying drawings, in which:
Fig. 1 is a fragmentary perspective view of a roof ventilator embodying my invention illustrated in installed relation on a shingled roof.
Fig. 2 is a fragmentary longitudinal section.
Fig. 3 is an enlarged fragmentary view in transverse section on a line corresponding to line 33 of Fig. 2.
Fig. 4 is an enlarged fragmentary view in section on a line corresponding to line 44 of Fig. 2.
Fig. 5 is an enlarged perspective view with the top and screen removed or omitted.
Fig. 6 is a perspective view of the top.
. Fig. '7 is an enlarged fragmentary perspective view of one of the integral side and base members.
Fig. 8 is an enlarged fragmentary rear perspective view.
In the accompanying drawing, l represents portions ofa roof, such as the roof boards. and 2 represents shingles. These parts are conventionally shown and are shown for the purpose of illustrating the installed relation of my ventilator to parts of a roof.
The embodiment of my invention illustrated comprises a flat plate-like front base member 3 and laterally spaced side base members 4-4 which are lapped upon the frontbasememberand secured thereto as by spot welding indicated at 5. The side members 1 are joined integrally with the sideib'ase' members 4 being joined there- 'by the outwardly" facing 'jseam elements or flanges 61Th'hood'side'members l are near- 2 wardly tapered and terminate in spaced relation to the rear ends of the base side members 4, but the seam elements 6 extend to the ends of the base members 4. The hood top member 9 has downturned side flanges ll] overlapping the outer sides of the hood side walls I and fixedly secured thereto as by spot welding indicated at ll. a
Thehood top member 9 is provided with a rear base member extension l3 formed integrally therewith and having inturned seam flanges 14 on its end edges which are engaged with the seam flanges or elements 6 joining the base side members with the side walls 1. The side flanges ID of the top merge into the flanges l2. These coengaging seam flanges or elements are parallel so that they may be engaged by a relative longitudinal sliding movement which greatly facilitates the assembling operations. With the parts assembled as shown in Fig. 5, the top and rear base members may be assembled therewith by a relative sliding movement, and when so engaged, the joints are all effectively sealed to the passage of Water. It will be understood that the parts are of such relative dimensions as to provide for the passage of air through the ventilator. The parts which I have referred to as base members constitute the flashing when the structure is installed on a roof.
By reference to Fig. 2, it will be noted that" the front end of the hood top extends beyond the front ends of the hood side walls and is provided with an inturned flange l 5 over which the upper edge of the screen I6 is folded. The lower. edge of the screen is extended rearwardly at IT upon the base member 3; The ends ofthe screen are bent forwardly into flange-like portions 18' which are disposed on the inner sides of the hoodv side walls 1 and secured thereto by means of the U-shaped binding strips [9 which embrace the front edges of the hood side walls and the forwardly turned edge of the screen (see Fig. 4),
and as illustrated, are secured by indenting or no possibility of leakage. v have illustratedand-described my invention in "a highly practical embodiment thereof -both member, hood side walls integrally connected too said side base members by folds prov-iding'out'-- wardly facing seam elements, the upper edges of the hood side walls being rearwardly inclined and. terminating in spaced relation to the rear ends of the side base members, the seam elements-extending rearwardly beyond the rear ends of the sidewalls, a hood top'member having downturned flanges onv its side edges overlapping the outer sides of the hood side walls and secured'thereto,
a rear base member integrally extended-from said top member and having inturned seam-flanges at its ends disposed in coaeting engagement with said outwardly facing seamelements, the side flanges of said top member merging into said seam flanges of said rear base member, the said coengaging seam: members being engageable by relativelylongitudinai sliding movement thereof, thefront end of said hood top-member projecting forwardly beyond the-hood side membersand having an inturned flange at its front edge, a
screen having its upper edge turned forwardly over saidinturned flange of -said hood top memher and having forwardly projecting end: portions disposed at the inner sides of said hood side-walls, and U-shapedbinding members disposed over the forward edges of said hood sidewalls to embrace the forwardly turned edges of said screen and clamped thereon.
2. A roof ventilator comprising a' front base member, laterally spaced side base members lapped upon and flxedlysecured-to the front base member, hood side walls integrally connected to saidside base members by folds providing outwardly facing seam-elements, the upper edges of the hood side walls being rearwardly inclined and terminating in spaced relation to the rear ends of the sidebase members, the seam elements extending rearwardly beyond the rear ends of the side walls, a'hood top member having downturned flanges on its side edges overlap-ping the outer sides of the hood side-walls and secured thereto, a rear. base member integrally extended from said top member and having inturned seamflanges at its ends disposed in coasting engagement withsaid outwardly facing seam elements, the side flanges of said topmember merging into said seam flanges of said rear base memben-thesaid coengaging seam members being engageable by relatively longitudinal sliding movementthereof, louvers disposed between said hood side walls in spaced stepped relation and fixedly secured thereto and constituting braces therefor, the lower louver being provided with a rearwardly turned flange on its lower edge, the rear. edge of thefront base member being bent upwardly and forwardlyto receive said-flange.
3. A roof ventilator comprising a front base member, laterally spaced. side. base members lapped upon and fixedly secured to the front base--member, -hood. side. walls integrally connectedma sise-pasa mbesbr emales-Fir ing outwardly facing and longitudinally extending groove-like seam elements, the upper edges of the hood side walls being rearwardly inclined and terminating in spaced relation to the rear ends of the side base members, the said seam elements extending rearwardly of the ends of the sidewalls and opening at the rearends of the side-base members, a hood top member having downturned flanges on its side edges overlapping the outer sides of the hood side walls and secured thereto, a rear base member integral with said top-member'and' having inturned seam flanges at its ends telescopically engaged with said outwardly facing grooyer-like seam elements of said sidebasemembers; the side flanges of the top member merging into said seam flanges of said rear. basemembenand a louver disposed between said side walls in rearwardly spaced relation to their front ends and constituting a brace therefor, the louver having a rearwardly turned flange on itslower edge, the rear edge of the front-base member. being bent upwardly and forwardly to receive said flange.
