SKYLIGHT QR VENTILATED ROOF.

Application filed August 23, 1920. Serial No. 405,306.

T all wit-Om it may concern. i Beit known that I, SAMUEL J. OLsHiN, a citizen of the United States residing at 1 Underclifi', Yonkers, in the county of Vestchester and Sta teof New York, have invented certain new and useful Improvements in Skylights or Ventilated Roots, of which the following is a specification.

This invention relates to'an automatically operated ventilator, One of the objects of the invention is topro videa ventilator that will open automaticallyin case of fire- Another object is to provide a ventilator that may be opened and closed manually'with a minimum of noise. Another object is to pro-vide a ventilator that is substantially air tight when in a closed position. Another object is to provide a ventilator that will not let rain into the building even when the ventilator is in its open position unlessthe rain is accompanied by a' considerable amount, of wind. Another object is to provide a ventilator that will in its closed position efi'ectively shutout rain even in the 2 most violent storm. "Another object is to provide a. ventilator byrneans of which adequate ventilation can be secured in a practical and convenient- 1nanner. Other objects and advantages of the invention will be ob- 0 vious asthe description proceeds.

The invention will be understood from the following description and the accompanying drawings. which show an embodiment of j the invention in which the same reference characters refer to the sameparts in the different views. I p

Inthe drawings: v p I I Fig. 1 is a side view of-the device as used 7 on the side of a peak roof; I s 4 Fig. 2 is a similar-view showing the sashes in a closed position on the other side of the peak roof; 7

'Fig. 3 is a plan view; Fig. is a perspective view showing a sash andoperating rods;

Figs. 5 and 6 are views showing details of the mechanism. s I I In the drawings reference character refers to. the rafters which are shown coming together at the .top in 'a peak roof skylight. Pivoted between the rafters 1 are series of window sashes 2, 2, 2, etc., so mounted that the'lower edge o-feach sash overlapsthe upper edge of the one below it when the sashes are in a closed position as shown in F The sashes are each provided with a pro ectmg hp 3 extending along the under slde of their loweredges andwith a strip 4 of resilient material such as rubber for ex ample extending alongthe top'sideof'the upper edge thereof. The strips 4 may be provldedwith notches 5 so as to fit more closely the framework'or outlines along the underside of the sashes above, with which they come into contact when they are in a closed position, thereby forming substantially air tight joints between contiguous sashes. i

v Extending from each side of the sashes 2, 2.,'etc. near the point 6 (Fig. l) at which the sashes are pivotedyare brackets 7 that are connected by pivots 8 to operating bars there being an operating bar 9 along 'e'ach side of every series or setof vertical sashes.

Each operating bar 9 is pivotally connected by a link 10that is also pivotally connected to an arm 11 which arin llis in turn rigidly connected to. the operating rod or shaft 12 whichis mounted to turn in bearings 13 mounted upon cross pieces 14: which are secured to the rafters 1 at a convenient height. The arm 15 is adjustably connected by means of a set screw '16'to the rod 12in such ajposition that the'arm15 comes into Contact with and isstopped in its travel by'the oper'ating sha ft or rod 12 for the sashes on the opposite side of the peak root skylight which is show iniFig. 2. .The operating rod 12' for its; side offthe skylight shown in its actuallposition in dotted lines in Fig.1, the views inthe two figures showing thetwo respective sides. of the skylight slightly separated from each other, and the sashes being shown open in one view and closed in the other view. It is obvious that by adjusting the position of the, arm 15 on rod 12 by means'ot-set screw 16* the extent to which the sashes can be opened will be determined.

The end of the arm 15 and theend of a corresponding arm on the rod 12 will be connected to thebifurcated end of a rope 17 which has a fusible link 18 therein.

i 'ltis impractical to mount the sashes 2 between Ith'efraft'ers 1 with a sufficiently close fitto prevent water from entering between the sides ofthe sashes and the sides of the rafters. In fact since it is desirable to have the sashesQ to turnfreadily on the r p vots it is advisable to have a small, free space between the two. This makes it necessary to provide a cover arrangement for these spaces between the rafters and the adjacent sides of the sashes. Such an arrangement is shown consisting of covers and 21 correspond ing to or suitable for each pair of side-byside sashes. substantially the same shape in cross sect-ion which shape is clearly shown in Fig. 5. The cover 20 is pivoted at the points 22 to the rafter 1 and its lower end extends a short distance below the point 6 where the corresponding sash is pivoted to the rafter 1. The cover 21 is of substantially the same Shape as the cover 20 and is fixedly connected to the adjacent edges of side-by-side sashes'in such a manner as to extend horizontally over the spaces between the sashes 2 and rafters 1, thereby forming a continuous sash. The upper end of the cover 21 terminates somewhat below the pivot points 6 so as not to interfere with the opening of the sashes. The cover 20 which is pivoted to the rafter 1 overlaps the upper end of the cover 21 and the cover 21 overlaps the upper end of the next lower pivoted cover 20. The cover 20 may be offset near its upper end as shown at 23 in order to facilitatethis overlapping." M v j The ,operationis as follows: VVhenit is desired to close the ventilator, tension is applied to the rope 17 whereupon the arms 15 are pulled downwardly and the operating rods 12 and 12 are turned in their bearings thus through the mediation of the arms 11, links 10, and operating bars 9 the sashes are all turned together about their pivot points 6 to their closed position as shown in Fig. 2. The resilient strips. a of the respective sashes come into contact withthe lower sides of adjacent sashes that are higher up thus providing a substantially air tight ven tilator. ,When the rope 17 is released or when in caseof fire the fusible link 18 is melted the weight of the rods ,9 etc. will turn the sashes to their openposition as shown in Fig. 1. If necessary the sashes may be so pivoted as to tend normally to turn to their open position by having the pivot points nearer their lower than their upper ends. By proper adjustment of the arm 15 on the rod 12.,the sashes can be made to stop at the desired open position with the arm 15 in contact with the lower side of rod 12. Preferably, this adjustment will be so made that when the sashes are in their extreme open position they will slope downwardly slightly thus takingcare of ordinary rain that does not-descend at too great a slant. When the sashes are being turned about their pivots 6 towards their open position the covers 21 are carried upwardly and the covers 20 are turned about their pivots 22, their lower ends sliding along the These covers 20 and 21 are of tops of the covers 21 to the positions shown in Fig. 1.

lVhile the invention has been described as applied to a peak roof ventilator it is obvious that it is also applicable to a ventilator that has only one sloping side. It is also obvious that since the usual building regulations permit the total area of glass to be as small as the area of the opening through the roof, a portion of the glass can be left off and sheet iron or other material substituted therefor. This modification does not violate the requirement that the total ventilate ing space when the sashes are open shall equal the opening throughthe. roof.
