WINDOW vENrILA'roR.

-Application led August 14, 1920. Serial No. 403,568.

This invention relates to window vent-ilators and has for its object the provision of a device which may be set in a window frame below either' sash and easily adjusted to admit a desired volume of air or to exclude all outside air and prevent the entrance of rain, snow, or other elements.

Another object of the invention is to provide means whereby when the ventilator is opened, guards will be provided to prevent side drafts and to screen the occupantsV of the room from observation 4from the outside.

Other objects of the invention are to proride means to prevent spreading oit the panels and the frame in which they `are mounted; to house the working parts within the Ytraine, so that they will be protected against breakage, and to provide an adjusting mechanism which will be simple and direct acting.

Other incidental objects will appear in the course oli the following description.

A preferred embodiment of the invention is illustrated in the accompanying drawings in whichi j Fig. l is an elevation of my improved window ventilator `viewed from the inside and in closed position;

Fig. 2 isa plan `view of the same;

Fig. is an enlarged verticalv section with the panels in partly open position;

Fig. l is an enlarged end elevation' of the closed ventilator;

fiig. 5 is a detail section ot a part of the ailjusting mechanism; Fig. 6 is an enlarged detail section showing the manner of connecting a` panel 'to the :nljusting shaft;

Fig. 7 a detail of the stay rod;

Fig. 8 is a section on the line SMS of Fig. l; and

Fig. 9 is an enlarged transverse section of the upper portion of the ventilator showing the closed relation ol the panels.

The ventilator comprises a frame l, which isv adapted toit in a window between the sash stops or beads thereon; it may be placed beljoxyv the raised lower' sash with the sash resting thereon or it may beplaced in the outer grooves below the upper sash, 'in which event thelower sash may be raised or lowered at will without requiring any shifting oi` the ventilator. One end strip" ol the traine may be adjustable longitudinally oi"` the frame so as to adapt the device to windows of different widths and this strip may be secured in a set position by a thumb screw 2. The frame may be provided on its top side or edge with a metal cover 3, adjustable transversely and secured in adjusted position by set screws 4 passing through transverse slots 5, the frame being thus adapted to 'lit under sashe's of various widths, and to allow of its extension in towards the room, to come under the lower sash, when the ventilator is set in between the stops that hold the upper sash. This to prevent the storm from coming` in between the ventilator top and the bottom of the lower sash when raised, the flange coming up on the inside of' the bottom of the lower sash the same as when the ventilator is set directly under the lower sash. The cover isV provided along its inner edge with an upstanding flange 6, which is adapted to engage against the sashand prevent the entrance ojl" water underthe same. The frame is rectangular to rest securely in the window frame and upon the sill and presents a central opening in which the Ventilating panels 8 are mounted.

The panels 8 are oblong strips of transparent or translucent glass or other material 'carried in inetal holders 9, which receive the ends of the strips and extend across their lower edges so as to firmly support the same. The holders project above the upper edges of the panels, as at l0, to form fulcrum lugs or ears through which pivot or fulcruni screws or pins l1, are inserted into the frame to secure the panels in place. The space between the holders over the upper edge ott' a panel is open to facilitate the removal of a broken panel and it will be readily understood that the heads of the pivot screws serve as retainers to prevent the panels being accidentally released from theholders. To further facilitate thewithdrawal of a broken panel and the insertion or' a new paneh'the wooden guard strips l2 on the inner side of the frame are secured in position by screws so that they may be easily removed and replaced. These strips, when in position, prevent rain or other weather elements beating around the ends of the panels into the room. The holders for the intermediate `panels are cut away "on their outer faces at their upper ends, as shown at 13, and on their inner faces at their lowerends, as shown at `la, so that the panels lmay be in intimate contact when closed as 'shown in Fig. 9, and

form a wind and dust-proof joint. As will be readily understood, the holder for the bottom panel is cut away on only its front face while the holder for the top panel is cut away on only its rear tace. y

ln the lower edge ot the top bar of the it aine l forni a groove or longitudinal chamber l5 having an upturned rib or flange 16 along the edge of its front wall and on the upper edge ot' the topV panel I provide an overhanging hook-like lip or flange 17 which extends` into the recess l5, and adapted to engage upon the rib 1G so that the weather elements cannot work over the top of the panel and into the room, as will be readily understood on reference to Fig. 9. The overhanging lip is carried on a base plate 18, which is litted snugly upon the top edge of the upper panel., as shown clearly in Figs. 3 and 9, and the holders 9 for said panel are expanded at their upper ends, as at 19, to accommodate the base plate and lip and hold them snugly on the panel.

One of the panels carried by a pivot rod Q5 instead ot'jthe screwsll, said rod extending through the upper extremities oi the holders and being journaled in `the side members of the traine. Rivets or similar astenings 2l are inserted through this rod 25 and the inner webs oi the holders to msecure the rod to the holders and these holders are enlarged, as at 22, so as to be sutliciently reenforced to sustain the strain of turning the panels. A wormpinion 24 is provided on one end of the rod 25 and meshes with a worm 23 on a shaft 20 whichl is housed within the end of side bar of the :trame and equipped at its free end with a milled knob or other torni of handle 26, wheieby a turning movement may be imparted to rod 25 to adjust the panels. It will be readily understood that the turning movement. of the pivot rod or shaft 25 shifts the angular positions `of the panels so as to open the ventilator to a greater or less degree.

'lo eii'ect simultaneous movement of all the panels, connecting bars 2G are provided at the ends oi' the panels `and the panels are pivoted to this connecting bar by pins or studs indicated by dotted lines at 27, thelpins or studs being spaced apart the same distance as the pivotal-connections of the panelswiththe frame so that the swing- .ing movement of one panel will be transmitted through the connecting bar to all the panels.` The panels will be held in the set position by the well known braking action o't' the worm gearinff. The connecting bars 26 are relatively thin and may be ot sheet material but they should obviously be long` enough to connect all the panels; they are preferably of such `width that their inner edges will rest against the facing guard strips l2 and their outer `edges will lie flush with the outer side oi' the frame when the ventilator is closed. The connecting bars are provided near their ends with arcuate slots 2S which play over pins 29 on guard plates 30 of similar dimensions as the con necting bars and arranged between-said bars and the sides of the :fi-aine. The guard plates 30 are provided near their ends with arcuate slots 3l playing on studs or pins 32 on the end strips of the lraine.

The holders 9 for the lowerlnost panel are extended somewhat below the lower edge ol the panel and a tic rod 33 is fitted at its ends in saidhohlcrs and is scoured to the same by rivets or similar devices 3st, :is shown. Spreading ot the holders and consequent release ot' the panel is prevented by the provision ot the tie rod and, as the pivots 2T are headed studs, the connecting bars will be prevented from falling away 'from the panels.

From the foregoing description, taken in connection with the accompanying drawings, the operation and advantages of the device will be readily understood and appreciated. When set in a window with the panels set as in Fie. 3, passages through which fresh air may iiow into a rooin are provided and it will be noted that the air currents must flow upward so that dust will drop to 'the outside of the window and the air passing into the room will be substantially 'tree ol impurities and air currents moving up wardly will not malte a draught to blow articles about the room or cause colds. To set the panels at any desired inclination, the shaft 2O is turned by manipulation of the handle 26', and the iiulcrum rod 25, will be rotated or rocked through the gearing shown and described. As this rod is connected rigidly with the adjacent panel holders, the panel, will, of course, swing as the rod rocksand the connecting bars 26 will transmit the motion to the other panels `su that all the panels will assume 'the saine in clination. As the panels swing outwardly, the connecting bars Q6 also, ol course, swing outwardly and ride upon the studs or pins 29 until the ends ot the slots 28 iinpinffo against the saine whereupon a pull will e exerted upon said studs or pins to draw the guard plates 30 outward so that the bars and plates together form guards or shields to preventlateral air currents entering the ventilator andto screen the occupants of the room from the view of persons standing at the side of the window. It the panels be swung inwardly the connecting bars and guard plates will telescope into the spaces between the ends ot the panels andthe adjacent end strips of the frame with their outer edges flush with the outside of the :trame so to present a neat appearance. Thus the side guards ext-end and close only so far as the panels are opened or closed. The device is simple in construction and till lUl

etlieient in use, serving the purposes of an awning, a window and a ventilator.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States isl. In a window ventilator, the combination of a frame having a longitudinal recess in the under side of its top bar and provided with an upturned longitudinal rib on the front wall of said recess, a plurality of panels pivotally mounted in the frame, t-he pivot oi one of the panels being elongated, a worm wheel fixed on said elongated pivot, a shaft disposed transversely to the worin uf'heel, means for setting said shalt, a worin on said sha'lt meshing with the worin wheel, and an overhanging lip extending along the top of the uppermost panel and playing in the recess in the traine to engage over and bear upon the upturned rib.

2. In a window ventilator, the combination ot' a frame, a series of panels pivotally mounted in the frame, means connected with one of the panels for setting the same, connecting bars pivotally connected to the panels whereby to effect synchronous moveinentot the panels, said connecting bars having arcuate slots, studs on the frame, guard plates having arcuate slots engaging said studs, and studs on the guard plates littin'g inthe slots in the connecting bars.

3. In a window ventilator, the combination of a frame, a plurality of holders pivoted at their upper ends in the frame, panels having their end edges engaged in said hold ers, connections between the holders, means acting on one panel to set the saine, and a tie bar disposed below the lower edge of one panel and having its ends secured in the holders carrying said panel.

4. In a window ventilator, the combination of a frame, holders having open tops, panels tltted at their ends in the holders with their top Vedges below the upper ends ot' the holders, and pivots extending through upper ends of the holders into the frame, and bearing on the upper edges of the respcetive panels, whereby to pivotally attach the holders to the trame and ret-ain the panels in the holders.

5. In a window ventilator, the combination of a frame, holders having open tops, panels fitted at their ends in the holders with their top edges below the upper ends of the holders, and pivots extending through upper ends ot' the holders into the frame and bearing on the upper edges of the respective panels whereby to pivotally attach the hold ers to the frame and retain the panels in the holders, the pivots of one panel extending entirely across the panel and heilig pinned to the inner webs of the holders and said `webs being enlarged to reenforce the fastening.
