COMBINATION WINDOI SCREEN, UVINDOV SASH, .AND VENTILATOR.

Application 'led May 28,

T0 all 'whom t may concern: i

Be it known that we, ROY E. CUMMINGS and Josnrrr V. SULLIVAN, citizens of the United States, residing at Eastport, in the county of l/Vashington and State of Maine, have invented certain new `and useful Improvements in Combination l/Vindow Screens, Window Sashes,'and Ventilatore, of which the following is a specication, reference being had therein to the accompanying drawings.

This inventionrelates to a combination window-screen, windowesash and ventilator, and has for its object 'the production of a simple and efficient device that can quickly be placed in a window-frame, or removed therefrom, for the purpose `of `ventilating a room. y f

Another object of `the invention is the provision of a detachable window-sash that can be quickly applied to a window-frame, whereby a room can be ventilated without permitting rain to enter the room, or caus` ing drafts in the room, direct upon a person, or persons;

With these and'other objects in view, our` invention comprises certain novel combina` tions, constructions and arrangements 'of parts as will be hereinafter described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings: p Figure 1 is a view in elevation, partly shown in. section, of an apparatus ccn-v structed vin accordance with the present invention.

Figure 2 is line 2 2, Fig. of the arrows. .i y Figure 3 is a vertical, `sectional view, taken on line3-3, Fig. 1,and looking `in the direction of the arrows, as the apparatus appears in open position.

d igure t is a fragmentary, sectional View, taken on lino 4;4, Fig. 3, and looking in the direction of the arrows. Figure an enlarged, fragmentary, sectional view of the apparatus, showing the hinged window-sash in a closed posim tion.

1, looking in the direction Referring to the drawings by numerals, y

l. designates the window-screen frame, and 2 is the window-sash frame, constituting a ventilating frame, this frame 2 is hinged, at 3, within the primary or screena sectional view, taken on n 1921. f Serial No. 473,538.

`We prefer `to use a window-pane d in this frame so that -a person can readily see.

through the entire apparatus; therefore, by

using a pane 1, the vision of a person in a room, looking rthrough the apparatus when it is in position within the window-frame, will not be obstructed.

Screws `5 are used to fasten the upper strip 6 (constituting part of the frame) in position; if the pane 4 is broken, the screw can .be removed, the strip 6 lifted off the frame, whereby a new pane can be easily assembled with the window-sash :frame 2, forming a part thereof.

An adjustableextension device 7 is formed upon one end of the primary or windowscreen lframe 1, and this extension device includes a strip 8 fastened by a fabric cover 9, to the end of frame 1, and positioned in sockets 10, in strip 8 are pins 13; in the end of frame 1, are coil springs .12, and pins 13 extend from the strip 8 within the springs 12, to guide the springs when they" are depressed snugly into the sockets 10 yand 11. This extension device 7 permits the apparatus to be quickly fitted into the window frame. y y,

On the other end of the primary or window-screen frame `1I maybe placed a strip `14C, whichstrip 14 is provided with pins 15 extending into the frame 1. yIt will `be obvious that any number of such strips 1li :maybe attached to the end of the win dow frame for increasing its size, "without departing from the spirit or scopo of' the present invention. .l y Flexible or fabric strips 16 are fastened., preferably by taclrs 17, to the inner, vertical edges of the primary or screen frame 1 just behind the wire screening or mesh 18. This ics mesh 18 is held in place by asuitable beadi ing 19, which beading 19 is secured to the front of the screen frame l. Additional taclrsl, Fig. 3, are used to secure the flexi- Eye screws 2O are fastened to the inside of the primary or screen frame 1,'neai its upper corners and close to the wire mesh 18. ldlye screws 21 are arranged in pairs and are secured to the inner face of the auxiliary or sash frame 2 at its upper corners; the eye screws 21 are placed in alignment so that the A tightly wound coil spring 22 is threaded through the inner eye screw 21 of each pair and permanently fastened to the outer eye screw, as clearly shown in Fig. 5; the other end of spring 22 is fastened to an eye screw 20. lt will be understood that the structure at both ends is the saine, as two coil springs 22 are used and the'peculiar positioning of the eye screw is of importance inasmuchV as the upper ends of the flexible or fabric strips 16 are over the coil springs, and when'the hinged frame is closed, the flexible yor fabric strips 1G `are away from the'in'eeting edges of the screen frame 1 and the sash frame 2, whereby no obstruction occurs during the closing action; in other words, the flexible ends, whereby the side draft is prevented, of the apparatus, when in closed condition, are placed well out of the way and permit of such closin as will produce an eficient apparatus. screws on the prima-ry frame 1 are at right angles to the eye screws on the auxiliary frame 2, and from practical experience, we have found that this peculiar arrangement produces a Very efficient and durable structure.

To hold the hinged, auxiliary frame in an open position, short pivot-ed rod 23 can be swung to the position shown in Figs. 1 and 3, or long, pivotally-mounted rod 24ey may be used if a greater opening is desired.

7e claim that our apparatus distinguishes from the ordinary screen in many respects, among which can be pointed out the fact that with anv ordinary screen the air rushes through the same instead of, going upwardly so as not to blow directly against a person that may be in the room; with our apparatus, when `in an open condition, air rushing through the wire mesh will strike the auxiliary or ventilator frame7 2 and said air is shot upward, almost perpendicularly into the room. The collapsible ends,

' constituted by the lex'ible'orfabric strips 16,

prevent the air in motion from escaping sideways, so that all fresh air, coming into the room through the wire mesh orv screening must, of necessity, be shot upward.` Itis also obvious that in case of sudden storms, no rain (water)` can' get into the room to destroy carpets, or furniture, orother decorations, because that which does come through the" screen strikes upon the glass or pane a and falls outward, or outsideof the building. In the event of very severe storms or when the" ventilation of the` room is such that no further air is desirable, the

t is to be noted that the eye hinged, auxiliary frame 2 may be closed and secured in place by the pivotally mounted button 25 on the primary screen frame 1 without removing the apparatus from the window, thus stopping all ventilation through our apparatus.

Our apparatus is designed to be of very great value and service in hospitals or rooms where persons are sick in bed in that 'they are protected from drafts. )In ofiices where persons occupy desks near windows they are protected from drafts and papers will not be blown from their desks and scattered about the room.

The apparatus is also of inestimable value when it is used toyeiitilate a room and the occupants of the room are asleep, or when a sudden rain storm arises because of the'absolute protection afforded by this invention, as herei'nbefore explained.V

While we 'have described the preferred embodiment of our invention, and have illustrated thesame in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the` art to which this invention relates, during the extensive manufacture of the same and we, therefore, reserve the right to make such alterations or changes as shall fairly fall within the scope of the appended claims.
