To. all whom it may concern: y l

Be it known that I, JAMES A. Srmmcitizen of the United States, burg, in the county of Allegheny andState of Pennsylvania, have invented. certainr new and useful .Improvements in Window-'Ventilators',

d cation, in which drawing ication. v l

My invention relates to ventilators and is especially adapted for service in the win-- dows of dwellings, oliCeS, etc.

'I he invention has for itsobjectl theprovision of ventilator means whereby freshan" of which the following is `aspecispeel-amena e: Lettere Patent. d Appumammea/Jdly. 2e, l190s. seal-N0. 444,993.

.residing a Piasf is taken'into the room and the impure air i withdrawn, said invention havingv certain new land novel features of construction and operation as will be hereinafter more fully described in connection with the accompanying drawings forming a part ofthis specifis: f F'gure I, is a frontA elevation of the inside of a window and attending frame, showing the application ofnny improved ventilator thereto.' Flg. 11 1s an'enla-rged transverse sectional view throl'lgh the same. Fig, III.` vis an end elevation of .the air outlet member- Views -having similar parts designated by I like numerals of reference.

The inventioncomprises an intake menuber which consists in'structure of an elon-I gated` frame, preferably formed of' sheet meta1, the' side walls 1 thereof having 'out-v wardly disposed flanges` 2-at the front and the base portion 3which is ada ted to engage? upon the sill proper 4 am has at itsv rear a downwardly disposed flange 4 -to en gage the sub-sill, said frame having its upper `portion 5 formedat an elevation below' that of the upper edge o :t the side walls and extends from the rear but part way inwardly so as to form a support for the lower vsash and carries-upon its mner upper edge a-weather strip 7 which is secured thereto by screws 8. Pivotally secured to the rear of and within the base of said frame is a movable vdeliector blade 9v-wh`ich inclines in an lupward direction through the open space at thev top, which blade has suitablyV secured to the upper surface thereof agauze'fabric or l Patented Dec. 1, laos.

screen wire-10 which is al'sosecured between Athe aforesaid weather strip 7 and top portion 5 of the frame. P ivotally secured atv the base of and within the front portion of, the frame is anadjustable support l1 the upper edge of which is tapered to a 4fine edge and enga-ges'a strip 'of'. wood .or other lsuitable material 12 of4 a non-slipping nature i attached to the underside of the deflector blade, said support carrying pins 13 whichv extend through radial slots 14 in the sidel walls of the fra1ne,`said slots being closed at thefront of the frame by the smal carried by the frame to limit the inward movement of' the support. Secured to the g side walls of the frame are the laterally disposed flanges 16 into which are loosely fitted Ithe wooden extension pieces 1,7 carryin weather strips 18 to engage the sash andsil Vand fillA up the space between the same and frame, which extension pieces I prefer be provided 'with small pins 19 to enter the sashv and assist in retaining the' same in position, The air outlet member consists of a frame `20p1'e1l`erably formedof sheet metal, to engage between the upper sash 21 and frame 22 plates 15 and is provided with a strip .23 at the topl topreserve a level. position with the inner portln of the frame and with a weather strip 24;y upon lts under slde to engage the inner port1on of the, sash, said frame having Ya rear wall 25 which extends down vertically and thence outwardly at an angle to a point -on about a level with the base of the ame leaving a narrow air .outlet space 27. This frame is also provided with a sci'eeu-27a11d, like that ofthe intake, is preferably elon- 'gated in form and is also provided with laterally dis osed flanges 28 between which engages woor en extensions 29 provided with weather strips 30 to fill up the remaining space between the window frame and sash.

In order to make the window .sashes secure against movement from the outside, I provide suitable fasteners 31 for the upper vsash 21'a1i'd fasteners 32 for the lower sash 6.

In practice, the 'deflector blade, which is I 'shown as occu ying its extreme inward inclmatlon, 1s a ]usted by mea-ns of the support 11, so as to open or close the space be- 'tween the blade and strip 7 to regulate the intake space and consequent amount of air ,f;-lesired, or shut oli' the supply if desired by moving the; plate 11 toward the deliector blade to cause the said blade to engage against the said strip When air is beingsupplied to the room, through the intake, as indicated by the arrows, aconstant circulation of air through the room is induced by the action of the external air currents upon the deflector lip 26 of the outlet member, causing a tendency to form a'vacuum in the outlet member with the result that the air in the room is drawn off through .the outlet member at the same time as fresh air is being supplied through the intake member.

By making the extension pieces 17 and 29 of wood, they may be readily shortened to tit any sized window.

At Fig. VI, the deflector blade 9 is shown as provided with a'toothed rack 12"which may be substituted for the previously mentioned strip ofwoodl2 to be engaged by the support 11.

Having thus fully shown andfdescribed my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a window ventilator, a frame adapted te engage between the lower window sash and the frame sill, theair inlet thereof embracing the rear and a portion of the frame top, an upwardly and inwardly inclined detlector blade pivotally secured at its base in saidfrarne, the free end of which extends into the spaceat the top of the frame and is adapted to be adjusted to regulate the flow of air therethrough, and an upwardly disposed member pivotally attached to the frame beneath the said blade for supporting and adjusting the latter.

2. In a window ventilator, a frame adapted to engage between the lower window sash and the frame sill, the air inlet thereof embracing the rear and a portion of the top of the frame, an upwardly and, inwardly inclined delector blade pivotally secured at its lower end to the frame, the free end of 1 which extends into the s ace at the top of the frame and is adapte to be adjusted to regulate the flow of air therethrough, an upwardly disposed member pivotally attached to the frame beneath the said blade for supporting and adjusting the latter, and a screen disposed across the .air inlet and attached to the frame and blade.

3. In a window ventilator, a frame adapted to engage between the lower window sash and the frame sill, the air inlet thereof embracing the rear and a'portion of the top of the frame, an u wardly and inwardly ineline'd deiector biirde pivotally secured at its lower end to the frame, the free end of which extends into the space at the to of the frame and is adapted to' be adjuste to regulate the iiow of air therethrou h, an upwardly disposed member pivotal y attached to the front of the frame beneath the, blade for supportin and adjusting the same, a screen dispose across the air inlet and attached to the frame and blade, andlaterally disposed members fitted between the sash and frame and against the ends of the venti* lator frame to fill up -the space therebetween.

4. In a window ventilator, a frame adapted to engage between the lower window sash andthe frame sill, the air inlet thereof embracing the rear and a portion of the top of the frame, an upwardly and inwardly inclined deflector blade pivotally secured at its lower end to the frame, the free end of which extends into the space at the top of the frame and is adapted to be adjusted to regulate the flow of air therethrough, an upwardly disposed member pivotally attached to the front of the frame beneath the detlector blade and is adapted to support and adjust the same, a screen disposed across the air inlet and attached to 1the frame and blade, laterally disposed members fitted between the sash and frame and against the ends of the Ventilator frame, and means arranged between the upper window sash and frame top to withdraw the impure air displaced in ,the room by the intake member.

5. In a window ventilator, a` frame adapted to engage between the-lower window sash and frame sill, the air`inlet thereof embracing the rear and a portion of the top of the frame, an upwardly and inwardly inclined deflector blade pivotally secured at its lower end to the frame, the. free end of which extends into the space at the top of the frame and is ada ted to be adjusted to regulate the fiow of air therethrough, a hinged door on the front of the frame the upper free end of which engages with and is adapted to adjust the. said blade, asi-.reen disposed across the said inlet and attached to said frame and blade, laterally disposed members fitted between thesash and winden' frame the inner ends of which engage bctween flanges carried by the ends of the ventilator frame, and means arranged be tween the upper window sash and frame top to withdraw the impure air displaced in the room by the intake member.

In testimony whereof I aiiix my signature in presence of two witnesses.

JAMES A, SHEA.
