, The general object is toprovide a frame and sash which are impervious'to' weather conditions, is practically air tight and locked against opening from the outside when closed, and is secure against accidental movementfrom any causewhenopen. f 10 A further object is to provide a small primary opening" without raising the lower part of the sash out of its sealedpositiom thus to provide some ventilation and still prevent ingress of rain. snow or sleet under any weather conditions, vand 16 whereby in the other open positionsthe'sash will prevent ingress of rain, snow orsleet except in very severe wind conditions and a sash which will prevent a harmful draft by'deflecting all of the incoming air upward. p, I 4 I 'An important object of our inventionjis' to provide a ventilating window which 'jcannotfbe moved or 'jarre'dfloose from any" position nor rattled by the action of the wind, and wherein any position it may be left' in, is practically a 25 locked position. 4 J A still further object is to provide a sash which may be; raised and swungl inward from] the top without being raised above' the top jof' the frame: I thus afvjery low ceiling willfnotiprevent a full 30 Op in thW Q With thetfore'go'ing and other objects inview our invention resides in' features of construction. the parts and combinations" thereof, as hereinafterfset forth and cilaimed and shown in the 35 faccompanyingdrawingswhiht. e i .1 isfa' front 'elevationfof. oneforrn, 0 our improved: frameiandvjsash; ,,.Fig. 2 is a side sectional view of maiden 'as illustrated in Figure, 1, 1 taken fon "line of Q pig. 3 is a iraction'alsection off ef:d'ev ii;e taken onjline 3-3 of Figure' 1..'

Weprovide a sashmade from barssimilarto the 'frame bars comprising the bottom rail jll, top rail l5 and side rails"l6l6; These four 10 members are preferably miter joined and welded slm'ilar to. the frame. The side members ll and I '6 are positioned, when the window is closed, as clearly illustrated in Figure 7; Theltop header l3 and top rail l5fare positioned when thevwin- 16 dow is closed,as illustrated in Flg ure a h bottom sill lo andithebottomrail I! are ,051+ tioned when the window is closed, asllclearly illustrated in Figures'2 and 3. .1, H p I Thus it will be seen that the, twofframes have 20 the same depth, whereby when thewin'dowlf is closed, thereare two spaced andsealed contacts, one", on the outside and one on' theinside and that we provide novelmeans which act to tightly I hold these contacting, e bersto e her, as: will Q'A'sj a matter of. lconveniencewe have illustrated our sash; havin six glass panes. Clearly the sash and frame'may be mademto a commodate I anynurnber and any sized panes an while,thev device. as, illustrated in Figure .1 is higherthan its width, the usualwindow for; the present purposeis somewhat greater in width than in height. It wiilbe noted byv scrutinizing Figures 5 and 8 p that. I our,improved}sash is opened, inwardly by swin in t e top awa from; th fr me n lift: ing the {sash from the bottom. The desired relaative openings .above and. below, the sash are secured by the length and positionof connecting links as will hereinafter appear. 1 The incom- 40 ing air at thetop .openingis directed upward thus forming a slight; yacuum, below; the ,sash vwhich tends to also direct the air upward, which enters below the sash, thus .:preventing harmful, drafts near-the fioor.

; Weprovidean angle bar vi 8, which {is secured to and positioned on sill. l0, as =illustrated'in;1?ig, ure 3, and a similar angle bar |9 is positioned similarly onsidejambs llll. Bars lfltermi nate as at go, I a portion, of a the inwardly .extend- ,lipjof I the angle" being bent, outwardly as l at zl thus to g a closure t the end ofthe guide channel formed by member l9. I .j rririe ow' i gure 1 a d 6;. '\wr;=., p' vldetwd links 2525, each being 'pivotally' se- 5 cured at their upper ends to members II as at 26, the washer 21 answering as a suitable spacer between the two members. The lower ends of links 25 are pivotally secured to side rails 18 as at 28, a washer 29 acting as a suitable spacer; thus when the sash is lifted, the upper end will swing away from the frame as illustrated in Figures 5 and 8.

We provide a drip cap 30 which is secured to member II and loosely embraces the outer flange of member II when the window is closed. as illustrated in Figure 3. We also provide brackets 3| which are secured to the bottom of member 30, as illustrated in Figures 2, 3 and 5, each having projections 32 which extend into the channel formed by member l3, thus to prevent the lower end of the sash from swinging inward and away from the frame.

We provide angle guides 33 which are secured to members l3 and IS, the rear end being positioned whereby when the sash is lowered, lugs 32 will contact member 33 and force the sash outwardly into its sealed position, as illustrated in Figure 3.

We provide means for locking the upper end of the sash into position as follows:

Spaced arms 35-35 are suitably secured to top header l3. as illustrated, each having cut out notches 36 and 35' on their under sides. Spaced brackets 33-38 act as hinges for the upper ends of depending loops 31, as illustrated. A loop extension 39 is suitably positioned to enter notches 36 and 36 when loop 31 is in the position shown in Figure 2, and to be disengaged when loop 31 is moved to the position shown by dotted lines in Figure 5. A spring latch 43 acts to lock loop 31 to the position shown in Figure 2. We provide a handle ll whereby the operator may easily move the sash by grasping loop 31 with one hand and handle ll with the other.

It will be seen that when the window is closed and loop 31 is in the position shown in Figure 2, the sash will be held in its sealed position and if loop 31 is then moved to the position shown by' dotted lines in Figure 5, the top of the sash will be moved out of contact with the frame and that the sash may be further moved to a position where member 39 will engage notch 36' whereby some ventilation is provided but without lifting the bottom of the sash out of its sealed position; thus clearly a heavy wind will not blow rain. snow or sleet into the building when the sash is in this position.

We provide stops 35 which are preferably positioned and shaped as clearly indicated in Figure 5; thus the sash may be moved so lugs 32 will rest on either pair of stops as indicated in Figure 5. The weight and position of the sash and action of links 25 will cooperate to hold the sash securely in either of the positionsprovided.

Thus is will be seen that the applicants frame and sash are light, strong. pleasing in appearance and especially adapted to the service for which they were devised. We have shown and described the preferred embodiment of our invention. Clearly many detail changes may be made without departing from the scope and meaning of the appended claims.

Having thus shown and described our invention, we claim:
