' VPatented Feb. 9, 1909.

Application filed December 12,1908. Serial No. 457,273.

To all whom fit may concern.'

Be it known that l, HENRY KRUC, a citizen of the United States ofAmerica, and a resident of Cincinnati, in thel county of Hamilton and Stateof Ohio, have invented certain new and useful Improvements in Window Ventilating Devices, of which the following is a specification.

This invention relates to window ventilating appliances, particularly to that class in which a Closure or safety device is used to enable either sash to be arranged and held in open position forventilation or the like, especially in warm weather, or in warm climates where such a deviceis necessary and most desirable. i rlhe invention consists in the provision of a pair of lazy-tongs gratings coupled so as to open `and close in unison and pivotallyconnected at their respective opposite ends to horizontal cross frame-bars, means for connecting said cross framabars to the sides of the window-frame, means for adapting said cross framebars to be locked in open position and means Vfor connecting the traveling upper cross frameebar with the open sash w ereby the latter is held in locked position readily accessible from the inside and the gratings prevented from being closed Y or operated except for authorized service.`

The essential features ofthe invention, including detailsy of construction, will be fully hereinafter described and particularly pointed out in the claims.

ln the accompanying sheet of drawings,

Figure 1 is a front elevation of my invention,

showing it in operating position in con- Y nection with an open window-sash, the view being taken on the innerside of the Window; Fig. 2, a central, sectional elevation of Fig. 1, but taken on a somewhat larger scale; Fig. 3, a fragmentary front elevation of the gratings and showing the upper cross frame-bar, but

omitting'the sashes and showing fragments of the vertical sides ofthe window-frame; Fig. 4, a ,front elevation of my invention, showing the device in closed position in connection with the lower portion of the window-frame` but omitting the sashes; Fig. 5, a

detail front elevation of oney of theV side socket-plates-used for the support andlocking-engagement of the` upper grating Cross frame-bar; Fig. 6, a view similar to Fig. 5, but of one of the lower pair of socket-plates "bolts used in connection with the lower cross frame-bar of the gratings; and Fig. 7, a horizontal section taken on line w, x, of Fig. 2.

ln these views, 1 indicates the window-sill, 2, 2 the upright Vsides of the window-frame and 3 the horizontal top of said-windowframe.

4indicates the lower sash and 5 the upper sash of the window, arranged as customary within said window-frame and adapted to slide vertically therein.

6, 6 indicates a pair of vertically-disposed lazy-tongs gratings coupled together by a pairof horizontal parallel bars 7 to prevent lateral sagging or tendency and so that they may operate in a direct perpendicular line into expanded, open position or into contracted closed position, as shown in Figs. 1

and 4, respectively.

f 8 indicates a lower horizontal cross framebar having laterally-operating. bolts 9, 9 at its op osite ends, the outer ends of such aving horizontally-projecting lugs that engage .slots 10 in plates 11 attached atV the lower ends of vthe . sides 2,2 of the window-frame. The slotted plates 11 are best shown in detail .in Fig. `6, the slots being@ elongated Vvertically and provided with" narrowed ends or notches 10a for the assage to and fro of the lugs on the bolts 9 w en the gratings are 'to be placed in kposition in the window opening or taken therefrom. When the gratings are in position said window opening, the lugs on the bolts 9 lie horizontally and are thus held firmly within the Cavity of the window-framesides back of the plates 11.

12 lindicates an upper horizontal cross frame-bar -to -which the upper ends of the lazy-tongs gratings are pivotally-attached,

the lower ends of said gratings being pivotally-attached to thclower horizontal crossbar 8, as best seen in Fig. 1. The upper cross-bar 12 carries a pair of bolts 13 having outwardly-disposed handles 14 at their inner ends and horizontally-disposed lugs 15 at their opposite outer ends, such lugs engaging horizontally-elongated openings 16 in plates 17 attached to the sides of the window-- frame about mid-height and the bolts turned a quarter of a revolution with the handles 14 disposed upwardly so that the lugs at the outer ends engage back of the plates 17 in suitable cavities provided in the said sides of are provided in the upper cross-bar the window-opening.

the `window-france. In order to turn the bolts said quarter of a revolution, notches i8 Y 12 and horizontal O'uide-wa s or slots 1Q are further n l u I n provided ror the sliding of said bolts inwardly and thereby releasing the lugs at their outer ends from engagement with the iorizontall-y-elongated slots of the plates 17. Notched corner lugs 20 are lprovided at the o i P lower portion of the plates 1! ror the seating oi the opposite ends oi' the upper cross-bar 12 when the gratings are in position tor closing 21 indicates a vertical tube slotted at 22 along its rear side and provided at its upper end with a projection orpin 2S, the latter engaging an eye 24 in the outer end of an arni 25 projecting forwardly from the center ol Athe .upper bar 26 of the upper window-sash, all as best seen in Fig. 2.

27, 27 indicate a pair of lateral arnis or lugs projecting in opposite directions troni the lowerend of the tube 21 and provided on their rear ends ywith inwardly-projeeting pins 28, shown dotted in Fig. 1, such pins engaging the openings 29 in each orp the two handles 14 of the sliding bolts i3, for the purpose oi sustaining said bolts 13 in their locked position and, also, for the purpose of supporting said tube 21 in vertical position in engagement between the eye 2d on the arm 25 of the upper sash and the upper cross-bar 12 of the gratings. rllhe gratings are thus held in their open position to properly close the opening beneath the raised lower sash when it is desired to ventilato or 4to leave said lower sash in its open position.

' 30 indicates a vertical rod provided wita a pin 3l projecting at its lower end inwar ily toward the apartinent and with a pin 32 proj ectingirorn its upper end outwardly into engagement with a inetal soclret 33 secured to the inner face oi the central portion oi the meeting-rail 34 at the top of the lower sash, as best seen in Fig. 2. This vertical rod 3() telescopically-engages the tube 21 lroni the lower end or inouth of the latter, the vertical slot 35 provided between the lateral-projecting lugs 27 and the upper pin end oi the rod being engaged with the upper meeting-rail of the lower sash and the pin 32 being adapted to ride vertically in the slot 22 oi the said tube 21. The pin 31 at the lower end of the rod 30 serves as a handle in sliding such rod vertically within the tuoe 21, but the ordinary ineans of raising the lower sash by talring hold of the lower bar or' said sash serves the purpose of raising the rod in the tube through the intermediary of the u; pin engaging the meeting-rail oli said lower sash. Said pin 31 is housed 'within the slot or opening 35 at the lower end of the tube 2i, as best seen in Fig. 2, and thus prevents the rod -from turning-strain within the tube and relleves the pin 32 at the top oi the rod from i arnese turning-strain in connection with its engagement with the ineetiirr-rail of the lower sash.

TWhen it desired to remove the grating device troni the win lo\\'-l"ranie, the followingl operation is pursued ze-The rod i3() is lirst lowered so that its lower end shall engage the opening 3G provided between the inner ends ot the ribs 37 of the lower cross-bar S, at wliich tinie the upper pin end ol" .iai d bar ran be swung outward liroin engagement with the meeting-rail of the lower sash and, also, from position at the lower end ol the tube 2l g said rod can now be entirely renioved troni the device and set aside the lower end ol" the tub-e 21 carrying the pins is thon swung outward so that said pins can become disengaged lroni the openings L@ in the bolt-handles 14 and then the tube can be lowered so that the pin at its upper end can be remlilv disengaged froin the eye 2a in the arni 25 at the upper end of the upper sash.; said tube can now be set aside the saine as said rod ,z the handles la on the bolts 13 are now swung inwardly(toward the operator) a quarter turn so that both bolts can he drawn inwardly freni engagement at their outer ends with the lock-plates 17 ,z the upper cross-har 12 is now raised troni seating-eiigageinent at its ends #ith the lower lugs 2t) on said lock-plates 1.7 and then swung outward slightly, thereby permitting the said opposite ends to clear said lugs 2O in the further downwaid moveaent of the upper cross-bar 12, the bolts E) sert/*ing as pivots until the quarter turn has been nia-de, at which tiine said bolts 9 can drawn inwardly for releasing` their outer lugged ends frein engagement with. the slotted plates 11.

Yhen the parts are in the position seen in Figs. 1 and f2, neither of the uf'iiniow-sashes can be nioved owing to the presence ol" the tube 21 and the rod 30 with their locking-pin connectionsin due engagement hereinbefore described and it is not possible lor any one on the outside ol' the window to enter the rooin or apartment through the grating, as access to the locking rod and pin devices is retarded and prevented by the lowering ol the open lower sash which is progressively clo. J 'ainst the hand ollr the intruder at all tin-ies noni the beginning oi the descent ner cross-bar to which the un ier end of said l i grating is attached, locking ineans on said upper cross-bar adapted to engage the window-traine and ineans between said upper cross-bar and the upper har ol the windowtraine to lock said grating in its open position for closing the opening of an open lower window-sash.

2. ln awindow-grating forventilating purposes, the combination of a lazy-tongs grating vertically eXpansible, a lower cross-bar having bolts at its opposite ends that Aare adapted to engage lock-plates in the windowfrarne and connected to the lower end of said grating, an upper lcross-har having bolts adapted to engage look-plates in the windowfrarne intermediate its upper and lower end and connected with the upper end of said grating, a tube having pins at its lower'end' sash.
