VENTILATING SYSTEM.
Specification of Letters Patent.
Patented Mar. '7, 1922.
Application filed October 12, 1920. Serial No. 416,403.
To (lilac/[0m it may concern Beit known that I, Ewcnn'r'r B. ARNOLD, acitizen of the Dominion of Canada, and residing at Hi hland Park, in the county of Vayn'c and tate of Michigan, have invented a new and Improved Ventilating System, of which the following is a specifi cation.
lhis invention relates to the construction of the roofs of factories, workshops and other buildings, and particularly those in which large quantities of dust, smoke and objectionable gases occur, and its object is to provide a structure of this character with novel ventilators at those points where they will be inost efi'ective, usually adjacent the highest parts of the roof.
, 1is invention consists in a roof structure formed with a series of sashes or panels longitudinally of the roof, and of any desired type or character, which panels are JlVGtflll y mounted and can be swung from hair normal longitudinal positions where they constitute a portion of the general plane of the roof to substantially transverse positions where they permit the free escape of dust, smoke and gases.
In the accompanying drawings, Fig. 1 is a transverse vertical section of a roof embodying my improved ventilating system. Fig. 2 is a portion of this section on a larger scale, with the movable roof sections in normal position longitudinally of the roof.
Similar reference characters refer to like parts throughout the several views.
The drawing shows side posts 1 which support one of a series of'roof trusses which embody the tension members 2 and the inclined compression members 3. On these compression members are mounted the frames 4 of any desired construction, and on these frames are mounted the hinges 5 for the roof section 6, which hinges may be of any desired construction so long as the roof sections may swing freely thereon. These roof sections, panels or sashes'fi may be of any desired types, character and construction and are preferably centrally balanced on horizontal pivots in order to permit easy operation. The frames 4 which are in alinement longitudinally of the roof are'preferably connected at the lower edges of their upper portions by the angle bars 7 against the lower sides of which the upper edges of the roof section 6 contact when swung to normal or closing position, that is, in the general plane of the roof and upon the upper sides of which the lower edges of these sections rest when the sections are. in normal or closing position. When these sections are swung to their normal position, as shown in Fig. 2, a continuous roof is obtained, but when they are swung to their perpendicular positions, as shown in Fig. l, the openings in the roof are suflicicntly great to permit the immediate escape of all smoke and gases therein.
The angles 7 embody the parts 12which arerin the general plane of and constitute stationary portions of the weather resisting surface of the roof. These stationary roof sections may be of any desired width so long as their upper edges extend under and constitute supports for the lower ed es of the next upper pivoted sections 6 an their lower edges overlap the upper edges of the next lower pivoted sections when these several sections are swung to the positions shown in Fig. 2, and while I prefer to form these sections 12 as integral parts of the angles 7, I do not but may build these sections 12 many manner and of any width and proper material. It is evident that in some cases these stationary sections may be omitted entirely, in which case the pivoted sections would overlap each other when swung down. The movement of the movable sections is preferably about ninety degrees, from the general plane of the roof to about per endicular thereto, although this angle" wif de land upon the construction ofth'e roof a fthe building and also upon the air condi ons adjacent the roof. I
It has been found that under certain conditions it is desirable to have a dividing plate 8 extend down into the building and to have deflectors 9 at an angle thereto, which plates and deflectors may be of well known metal lath and plaster, and aid the natural escape of dust, smoke and gases by preventing cross currents of air through the roof openings. thus permitting the ventilators at each side of the roof to do maximum work. \Vhen there is very little gas or smoke in the building, or during inclement weather, the ventilator 10 having the branches l1 connecting to the spaces on each side of the division plate 8 may be found suflicient to carry off such smoke and gases. The number of these ventilators and their wish to be limited thereto dimensions will depend uponth e size and character of the building as will also the use of suction fans therewith.
The number of these pivoted and stationary roof sections and theirsizes and proportions will be determined by the constrguction and size of the building to be ventilated and the character of the occupation followed therein. The mechanism for operating these ventilators is not shown, as any desired transom lifters or standard sash apparatus may be adapted for this purpose, and such operating mechanism may be operated or controlled mechanically or electrically to obtain the desired openings, but such devices form no part of this invention and are therefore not shown.
I claim 1. In a roof construction, the combination of a series of roof trusses and frames mounted thereon the upper part of each frame extending parallel to the general plane ofthe roof, a stationary roof member at the lower ends of the upper part of each frame constituting portions of the weather resisting surface of the roof, and movable sections pivoted on said frames at the upper ends thereof and adapted to be swung from normal position in the general plane of the roof to ventilating position at an angle to the general plane of the roof. I 2. In an inclined roof, a series of sections pivoted intermediate their upper and lower edges to swing from positions where they constitute portions of the same weather rcsisting surface of the roof to positions at an angle thereto, means to pivot-ally support said sections and normally stationary longitudinal sections of said roof extending above the upper edge of one and below the lower edge of another adjacent pivoteabscctions when they are swung to constitute portions of the weather resisting surface.
3. In an inclined roof, a series of sections pivoted intermediate their upper and lower edges to swing from positions where they constitute portions of the weather resisting surface of the roof to positions at an angle thereto, and means to pivotally support said sections comprising frames so constructed as to permit the pivoted sections to be swung to positions at right angles to said surface of the roof.
4. In a roof construction, a truss comprising an inclined compression member, a series of frames mounted on the inclined member, and roof sections pivotally mounted on said frames to swing to ventilating positions substantially perpendicular to said inclined members and at the upper sides of said frames.
5. In a roof construction, a truss comprising an inclined compression member, a series of frames mounted on the inclined member, and roof sections pivotally mounted on said 1 "allies to swing to ventilating positions substantially perpendicular to said inclincd members and at the upper sides of said frames, the heights of said frames being greater than those portions of the pivoted sections which extend toward the top of the roof from the pivots when the sections are in normal position.
6. In a roof construction, a truss comprising an inclined compression member, a series of frames mounted on the inclined member, roof sections pivotally mounted on said frames to swing to ventilating positions substantially perpendicular to said inclined members and at the upper sides of said frames, and stationary roof sections connecting to said frames to extend between and overlap adjacent pivoted sections when in normal position.
T. In a roof construction comprising two inclined sides and a supporting framework therefor. a dividing plate extending downwardly adjacent the top of the roof, a series of frames mounted on the framework of the root on each side of the dividing plate, a series of roof sections pivoted intermediate their upper and lower edges to swing from positions where they constitute portions of the weather resisting surface of the roof to positions at an angle thereto, and stationary roof sections to complete the weather resisting surface.
