Patented Dec. 29, 1936 UNiTED STATES PATENT OFFICE 24 Claims.

This invention relates particularly to window constructions for tall buildings and the objects of the invention are to provide a practical construction by which the window structure may be more readily harmonized with the architecture of the building; to facilitate the setting up of the windows in the building structure; provide practical and durable weather seals at all joints; to hold the window sash against rattling and to keep the action of the window sash quiet and smooth and easy to operate; to enable ready inspection and repair of the normally concealed sash connections and the like, and to provide a thoroughly desirable construction, which for its advantages will be relatively inexpensive and will be entirely practical commercially.

The foregoing objects are attained by the novel construction, combinations and relations of parts hereinafter disclosed and broadly claimed.

The drawings accompanying and forming part of the specification illustrate certain practical embodiments of the invention, but it is to be understood that the structure may be modified as regards the present disclosure without departure from the true spirit and broad scope of the invention.

Fig. 1 is a face View or front elevation of the window structure as incorporated in the building structure; Fig. 2 is an enlarged broken sectional detail as on the plane of line 2-2 of Fig. 1 and showing particularly the weight box and the sash guide plate closing the open inner side of the box; Fig. 3 is an enlarged sectional view as on the plane of line 3--3 of Fig. 1 showing the joinder of two horizontally related window units; Fig. 4 is a broken vertical sectional view as on the plane of line 44 of Fig. 1;

Fig. 5 is a broken vertical sectional view as on line 55 of Fig. i;

Fig. 6 is a broken detail illustrating the securing of one of the spandrel panels in the sill portion of one window frame;

Fig. 7 is a broken vertical sectional View as on substantially the plane of line 'l'l of Fig. 1;

Fig. 8 is a horizontal sectional detail as on the plane of line 88 of Fig. 1 illustrating the construction of the spandrel panel;

Fig. 9 is a broken part sectional View of a frame construction for glass panel spandrels;

Fig. 10 is a broken sectional detail illustrating another method of securing the spandrels in the hollow sills.

Fig. 1 illustrates an assembly of four window units connected horizontally and vertically to form a continuous vertical panel effect in the building wall 20. This continuous panel effect may be extended any number of floors to meet the architectural requirements of the building and if desired, the panel effect may be widened to include more than two window units horizontally. Each of the window units consists of a frame made up of a head 2! and sill 22 connected by weight boxes 23.

The weight boxes as shown particularly in Figs. 2 and 3 are of hollow three sided construction secured at top and bottom to the head and sill respectively and arranged with their open sides faced inwardly of the frame and terminating in inwardly directed flanges 24. These hollow shells may be made of relatively light sheet metal reinforced by intermediate partitions 25 dividing the boxes into front and rear compartments for the sash weights 26.

The open inner sides of the weight boxes are closed by the sectional sash guide plates 27 having outstanding, inturned

flanges

28, 29, along the front and rear edges and an intermediate T-section parting rail 30, defining guides for the upper and lower sash 3|, 32, respectively.

The guide plates are sealed to the weight boxes plates and clamp bars and by passing through openings 36 in the weight box flanges 24 definitely locate these parts on the weight boxes.

The guide plates are made up of vertically distinct sections separable on horizontal lines 31,

Figs. 4 and 5, which sections can be independently removed upon taking out the screws 35, to give access to interior portions or parts inside the weight boxes. As shown particularly in Fig. 5, the reinforcing, leading or clamp bars 34 cover the joints between adjoining sections of the guide plates and the

angle pieces

38, 39, close the joints between the guide plates and the head and sill of the frame. Thus, the structure is tight and weather-proof and at the same time any sections of the guide plates can be readily removed and be as easily replaced.

The upper sections of the guide plates are shown as carrying brackets 40 for thepulleys 4|, over which the window weight straps 52 are run so.

that the removal of the upper guide plate sections enables the taking out of these pulleys for inspection or repair. The pulley brackets are indicated as detachably secured on the back of the guide plate sections by screws 43, with the straps,

. to keep this weathering tight. At rails of the sash, similar weathering may be protapes or chains passing through slots 44 in the guide plates and down and up around pins 45 secured across the flanges of the sash (Fig. 2) and caught beneath the screws' lfi set in the heads of the sash. On loosening these screws which are easily accessible in the top of the sash, the tapes may be removed or secured in other adjusted relations, to take up for stretch, or the like.

To prevent the weights from being noisy in the boxes, they may be equipped with bumpers 41' in the form of bands of rubberor other cushioning material seated in grooves 48a surrounding the weights as illustrated in Fig. 5.

To keep the sash quiet, bumpers of rubber or other suitable material may be provided in the upper corners of the upper sash and in the lower corners of the lower sash as indicated at 48, 49, V

Fig. 5 and-bumpers or cushions 50, 5| Fig. 4 in the lower end of the upper sash guide and in the upper end of the lower sash guide to be struck by these sash whenthey are thrown fully open.

, The pulleys are mounted in centered relation over the

sash

31 and 32, and this fact, with the provision of adjustable sliding spring shoes 52, secured near the top and bottom in thevertical channels of the sash and sliding in the grooves of the sash guides, together with the special spring weathering strips 53, Fig. 2 held in the pockets behind the inturned

flanges

28 and 29 of the sash guide plates and engaging the edges of the sash, insure smooth and quiet operation of the sash.

These weathering strips are shown in Fig. 2 as three sided sheet metal strips 53 seated in the rectangular pockets behind the

angular flanges

28, 29, and having bowed spring edge portions bearing against the face of the guide plate and outwardly flared springWings or flanges 55 bearing against the edges of the sash. This same type of weathering is carried out at the parting rail in a double form of weatheringstriptlfi caught be-' neath the T rail and having the outwardly flaring spring wing portions 5'! engaging edges of the sash opposite those engaged by the spring flanges 55. This construction yieldingly centers the sash in the guides and keeps them weather-tight. along the vertical edges. In the channels across the top of the upper sash frame, between bumpers 48 and across the bottom of the lowersash frame between the lower corner bumpers -49, U-shaped weather strips 58 are seated having introverted or reversely bent edges 55, Fig. 4, forming'springs 1e meeting vided as illustrated in Fig. 4, where the U-shaped strip 58 is shown seated in a groove provided by an outstanding angle piece 68, secured on topof the lower sash frame and adapted to cooperate with an inwardly extendingpiece El secured to I the bottom of the upper sash frame.

At the ends, themeeting rails of the sash may be centered and sealed by the wedge blocks 62 secured on the face of the parting rails in position to be engagedby reversely faced wedges 63 the lower sash to close up any gaps at this point.

While each window unit is complete and may be used singly as such, the units'ar'e particularly well adapted for being combined in continuous panels after the manner illustrated in Fig. 1.

In eflecting this result, the horizontally aligned of an upper window frame.

window frames are combined as shown in Fig. 3 by connecting the weight boxes of horizontally adjoining frames in edge-to-edge relation, as by means of

cover plates

64, 65, fastened in the

inset portions

66, 61, at the inside and outside portions of the boxes as by means of screws 68 concealed in the weight boxes. These inside fastening inside the weight boxes when the sash guide plates are removed. If desired, the frames may be secured inhorizontally engaged relation by other means and the inset or shouldered portions 66 and/or 61, be left uncovered to form portions of the architectural details. The covered or bonded condition is illustrated in Fig. l and this view, with Figs. 4 and 7 shows how the vertical spaces between windows of adjoining floors may be covered by ornamental or other spandrels 69 between vertically aligned window frames and by intermediate spandrels 10 in linewith the cover plates 65. 7

As shown particularly in Figs. 4, 6 and 7, the spandrels 69 may be secured and supported by having their lower edges hooked in engagement over the upstanding flanges H on the head of a lower window frame and their upper edges caught behind the dependent flange or lip 12 on the sill In the views referred to, the hooked engagement at'the bottom is provided by a hook, lug or lugs 13, secured on the back of the spandrelto engage over the upstanding, flange H on the head of a window frame and the upper edge of the spandrel is locked in'po'sition back of the'lip of the sill by a wedge or wedges l4, dropped down through an? screws 68, it will be noted, are readily accessible weight box, Figs. 2 and 6, the wedge being indicated in the latter view as shouldered at 16, so that it can be forcedover into interlocked en gagement beneath the sill and held thus by small wedges l1 dropped into position at theopposite side of the shouldered wedge. In placing the spandrels, as with locating the other parts, suitable calking may be employed as indicated at 18 ing structure.

To prevent the weight of the spandrels from crushing down the hollow heads of the window frames, filler pieces 19 may be inserted in the hollows of these heads as shown in Fig. 4 to transmit the weight of the spandrels 69,10, to

r The intermediate spandrels 10 are indicatedin Fig. 7 as held in position by the intermediate cover plates 65, the latter having portions 80 overlappingthe edges of the intermediatespandrels.

Fig. 8 illustrates how'the spandrels may be bonded to the wall surfaces at the outside edges by suitable calking 18 and this view also shows how the spandrels may be made up as channeled frames 8| having the spandrel panels 69, set in the grooves of the same. This construction may be modified as in Fig. 9, which illustrates a corner'of the spandrel frame within the top bar outer channel of the side bar of. the frame, where" it is removably held by screw 85. Such aspandrel frame is well adapted for holding a panel 86 of glass, bright metal, vitreous material, or the like.

Instead of only the hooks at the bottom, the

spandrels may have hooks at the top as illustrated in Fig. 10, where hook lugs 81 are shown provided at the forward upper edge of the spandrel engaged over the inwardly hooked lower edges 88 of the lip of the sill, eliminating the need for the wedges 14.

As shown particularly in Figs. 4 and 10, an angle piece 89 may be welded or otherwise secured on the underface of the sill back from the lip 12 of the sill in position to fit the wall in back of the spandrels. This angle thus positions the sills of those frames which carry the spandrels, and as particularly shown in Fig. 4, form abutments for the spandrel holding wedges 14, the same being substantially in line with the wedge openings 15 in the top of the sill.

The spring weather strips 58, Fig. 4, in the channels in the top of the upper sash and in the bottom of the lower sash, when not compressed project slightly beyond the edges of the sash substantially flush with the bumpers in the corners of the sash, so as to make effective sealing engagement with the head and sill portions of the frame.

The pulleys are mounted on the back of the upper sections of the sash guide plates to carry the sash chains or straps up through the slots in the guide plate in exactly centered relation to the sash, so the natural tendency of the sash is to run true. But, in addition, the spring weather strips in the pockets of the sash guide plates engage opposite faces of the sash to prevent rattle and the adjustable spring sliding shoes near the upper and lower corners of the sash guide and hold the sash against edgewise movement. The guide plates are completely sealed to the weight boxes, but may be easily taken off and replaced in sections without injury to such sealing. The cover plates between adjacent window frames are attached by screws disposed inside the weight boxes and hence are entirely concealed in the finished structure. The spandrels are secured at top and bottom, either by hooks at top and bottom or by hooks at the bottom or wedges at the top, back of the lip of the sill and the weight of these spandrels is transferred to the vertical members of the frames, which are well capable of sustaining such weight.
