(CLIZSS-ZD 7 Claims.

This invention relates to a window construction of either projected or top hinged type, and more particularly t0 the operation thereof.

It is among the objects of this invention to provide a window the frame of which may be narrow, but of great strength to support large panes of glass without deflection. Another object of the invention is to provide a window operator having pairs of links on either side of the sash controlling the opening 'and closing thereof and supportingV said sash in open position, one link of a pair being entirely outside the sash when the sash is in closed position and the other link of thepair beingY entirely inside the sash wherebyv the `seal between the sash and frame is not brokenby the connection of the links to the sash,A or the links themselves when the sash is in closed positionand a weather tight window is provided. Another object is to provide a window of the'above nature which can be installed with a number of vothers of the same nature, and allv of which maybe operated simultaneously. Another object is to provide operating ,mechanism for a single window or for a group of windoWs' of the character referred to. A further object is to provide a window operator particularly for pivoted sliding type windows in which only a small operating member extends inside of the plane of the frame and laterally outside of the area of thel window openings irrespective of the position of the sash whereby. screens, Venetian.

blinds, blackout curtains or the like may be conveniently mounted on the inside of the frame and will not be interfered with by the operator.

Other objects will be in part apparent andin section of a portion of the operating mechanism taken along the line 3-3 of Figure l;

Similar reference characters refer to similar parts throughout the views of the drawings:

Referring rst to Figure 1, the building wall Ill has mounted therein a frame generally indicated at Il, divided into fixed windows l2 and operable windows IS. Windows i3 may be installed singly in groups or alternately with xed windows I2, as shown, or in any other desirable combination, and being of the projected casement type, as better shown in Figure 7, may be pivoted outwardly by operating mechanism which will be described below.

As shown in Figure 1, frame il comprises subsill, jamb and header members i4 (see also Figure '7) which preferably are steel angle bars of suitable weight mounted in the wall of the building. These bars I4 surround the frame proper, and accordingly constitute a rigid reinforcement therefor. The frame proper, in turn, for a single window, comprises as shown in Figure '7, head, sill and jamb bars l5 of suitable cross section formation to receive in sealing engagement the top, bottom and side bars I6 of window sash I3.

In the particular construction shown each bar l5 includes the base 1B, the inside striking flange il and outside striking flange l2. The sash bars I6 include inside striker surface lli 'and outside striking flange 1E. The flange 'l5 and the striker surface may conveniently be joined by web l1.'

When the window is in closed position, the base l, flange 1|, web ll, flange 'l5 and flange 'I2 form a closed or dead air space which effectively prevents seepage of air from the outside to the inside of the window there being two complete seals about the four sides of the window.

Other constructions of sash and frame havingY other forms of sealing contact may be used with the operator of this invention as it will be seen that in no case does the operator interfere with the seal between the frame and the sash.

As shown in Figure l, projected easement sashes i3 are arranged in pairs horizontally and each horizontal pair of projected easement sashes is separated by adjacent pairs of fixed sashes I2. Projected Casement sashes I3 and also fixed sashes I2 are separated by a mullion generally indicated at Il. Mullion il (Figure 2) includes a mullion bar` iS suitably secured to a steel supporting and reinforcing strip I9, the Vertical extent of which is (3o-extensive with the entire window panel. Mullion bar I3 includes opposite corners of sash I3, the other upper corner thereof being similarly connected to another guide 2l (Figure 2) secured to mullion bar I6 of mullion I'I. Guides 2i) and 2| are substantially identical, and include a channel 22 partially closed by a pair 'of flanges 23 and 24 (see also Figure 4).`

At each end of upper sash bar I6 (Figures 4 and '7)v is Secured a sliding pivot generally indicated at 25, comprising a roller 26 (Figure 2) mounted on a stud 21 extending from the body 28 of the part. Roller 26 is shaped to nt within channel 22y of guide ZI so that sash I3 (Figure 7) may be pivoted with respect to its frame, and may also be slid vertically with respect thereto. To prevent sash I3 from dropping completely out of its frame,'the bottoms of guides 26 and 2l are closed as at 29 (Figure 4)'. It may now be seen 'that sashes I3 are of the projected easement type. but we do notmean to be limited to this type of construction as the pivoted projected easement window is within the contemplation hereof- Referring back to Figure 7, each side bar I6 of sash I3 has an ear 86 mounted on the outer face thereof; pivotally connected to ear 66 is oneend of carrier link 3i) the lower end of which is pivoted to a lug 3| connected to'and eXtending from the outside of the window frame I5. At all positions of the sash I3 in the frame I5 the carrier link 36 will lie outside of the window opening dened by the frame and laterally outward therefrom and in the closed position of the sash will be as shown in Figures 5 and 6 in position substantially,parallel to the plane of the closed -sash and outside the frame. Carrier link 30 andthe bottoms 29 of guide channels 29 (Figi ure 4) limit the pivotal and vertical movement of the window, respectively. It will appear that by variation in the dimensions of the guide channels and links, the extent to which the window may be opened may be varied.

As shown inFigure 7, jamb I4 has secured thereto inside the plane of the sash when closed, a channel generally indicated atV 32, a substantiallyr similar channel generally indicated at 33 being secured to reinforcing bar l of mullionv I7 (Figure 2); Channels 32 and 33 are identical, and accordingly include sides 34 and inwardly extending vilanges 35 which together comprise a guide for a block 36 or-the like having an extension 3'! extending outwardly ofthe channel between - flanges 3,5. The bottoms of channels 32 and 33 are suitably closed to prevent blocks 35 from falling therefrom. Each of blocks 36 has pivotally connected thereto an operator link 38 (Figures 2 and 7)the other end of which is pivotallyconnected to side bar I6 of window i3 through striker surface i4 but laterally inward of the sash so as not to interfere with the seal between striker "I4 and flange 'II of the frame (seca-lso Figures 5. 6'and 8). Thus, 1119011 Vertical downward movement of block 35 (Figure 7) window I3 is not only lowered vertically, but is also pivoted outwardly, the extent of its movement being limited by the vertical travel of block 36, The link 38 being pivoted to the block inside the .innermost position of the sash and thru the striker surface of the sash bar will thus lie at all times inside of the sash in all positions thereof. When the sash is closed the link 3S lies in the position shown in Figures 5 and 6, substantially parallel to the closed sash and in conveniently disposed position iiat against the frame but eX- tending inward no further than the channel 32. This arrangement permits lthe operating parts inside of the closed sash to be conveniently enclosed in the side fra-me casing 59 (see Figures 1 and 2) and in any event such parts do not eX- tend inside of the innermost portion of the frame (See Figure 7) whereby screens, blinds, blackout curtains and the like may be mounted on the frame in close relation to the sash without interfering with the operator.

As shown in Figure 7, a rod 39 is connected to the bottom of block 36 (see also Figure 5) and the bottom end of this rod is adjustably threaded into a suitable coupling 46 (Figures 6 and 7) being held in its adjacent position by a nut 4 I. The lower end lof coupling 40 is suitably machined so that the top link of a link belt 42 may be attached thereto. Link belt 42 is trained around a driving sprocket 43 mounted on the end of an operating shaft 44 rotatably mounted in a hanger i The other end 42a of link belt` 45 or the like. 42 is connected to another rod `45, the upper end of which is threaded into a nut. The upper end of nut 4l threadably receives another rod 48,

the upper end of which (see Figure 4) is con-` nected to a flexible chain or the like 49. Chain 49 is trained over an upper pulley 59.

Referring to Figure 5, the upper portion of block 36 is formed to receive a rod 5I which eX tends upwardly therefrom as shown in Figure 7,

in Figure 1, each window is provided with opero ating mechanism such as that shown in Figure 7,

and these mechanisms are interconnected so that only one operator such as will be vhereinafter described is needed to operate both windows simultaneously. Y

By yway of summation, and with reference to Figures 4, 5 and 6, upper and lower sashes I3 respectively are operated by blocks 52 (Figure 4) and 36 (Figure 5), these blocks being interconnected by rod 5l. The upper end of block 52 (Figure 4) is connected to the lower end of block 36 (Figure 5) as follows: Chain 49 (Figure 4) rod 48 (Figures 4, 5, and 6), nut 41 (Figure 6), rod 46, link belt 42, coupling 49 and rod 39 (Figures 5 and 6). Thus, upon operation of sprocket 43 in one direction or another, vertical movement is imparted to blocks 36 and 52, and in accordance with the direction of movement sashes i3 are opened or closed. To maintain the various rods, chain 49 and link belt 42 in proper operative tautness, nut 41 (Figure 6) and also nut 4I may be adjusted. Also, to preclude blocks 35 (Figure 5) and 52 (Figure 4) from traveling out of their respective channels upon operation, the

with a worm'54: suitably mounted on a shaft 55 journaled in a bracket 55.` Shaft i/Leear, worm 54 and its shaft55'comprise the operator for the mechanism above described, andvmay be housed, if desired, in a suitable casing 5T through the side 51a of which shaft 55 may extend to rel ceive Van operatingcrank 53. A casing similar to casing 51 may be provided, 'if desired, to en-Y closethe operating mechanism shown in Figure 7, a casing of this nature being indicated at 59V irl-Figure 2.

Upon rotation of crank 5&3, sprocket 53`is ro' tated' `clockwise or counterclockwise to operate sash I3. Upon counterclockwiserotation, block 36is slid' upwardly in its channel 32v and by rea/-v son of theconnection` between the block and sash i3 by'link 38, the sash is both lifted and pivoted toward its closed position until at the yupward extent of travel of the block thesash is securely shut in its frame. Similarly, upon clockwise r'otationof sprocket 43, block 3S slidesdownwardly permittingsash I3 also to slide downwardly within its frame and also to pivot outwardly there" from. At thesame time, by reason of the connection between blocks 36 and 52 afforded by rods 48 and 5l (Figure 4) the upper sashes I3 are operated at the same time, and in the same manner.

Thus, it will appear that an indeiinite number of vertically arranged sashes of the nature described may be operated simultaneously through one simple mechanism. As the upper bar of the sash is constrained to slide within the plane of the window frame, the advantages of a projected easement window are attained without the disadvantages resulting frorn the usual complicated structure generally used in easement windows of the projected type. It will also appear that the operating mechanism described is equally applicable to a Casement Window of the pivoted type.

Accordingly, we have provided a window construction by which we attain the various objects set forth hereinabove in a thoroughly practical and efficient manner.

As many possible embodiments may be made of the above invention and as many changes might be made in the embodiment above set forth, it is s to be understood that all matter hereinbefore set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
