12 Claims. (Cl. 20-53) This invention relates to window structures, and particularly to a tier of windows, preferably of the type used in the South. They are the so-called awning type WlH- dow and include the mechanism for operating the same.

Among the objects of the present invention is to provide in the above type of window construction a novel type of hinge mechanism by which the window sashes may be swung about horizontal pivots and wherein the hinge construction is formed so that the metal of the hinge will embrace the vertical side members of the window sashes on opposite ends of the sash in a manner so that the stresses and strains are not placed upon the fastening screws that fasten the hinge members to the sash frame members.

Another object of the invention is to provide a combined hinge part member and window sash operating arm, all in one piece, thereby providing a more economical and rugged structure for accomplishing the two functions.

Yet another object of the invention resides in the provision of a hinge structure for pivotally mounting the upper ends of the window sash to the vertical s1de members of the enclosing window frame in such a manner that the upper sash may be adjustably slid downwardly with respect to the stationary portion of its hinge to permit an operator to reach outwardly above the top of the downwardly adjusted sash for cleaning purposes.

Another object of the invention resides in providing a hinge member for a window wherein the hinge members are vertically adjustable with respect to one another in one position but are locked from such vertical adjustment in another position.

Another object of the invention is to provide a hinge for a window construction which not only permits one of the members of the hinge to swing upwardly and downwardly about a horizontal axis but also in an adjusted position permits said hinge member to shift bodily upwardly and downwardly with respect to its complementary hinge section to permit cleaning of the window sash.

Yet another object of the invention resides in the provision of a Weatherstripping for sealing the joint between the upper horizontal frame member of the window sash and the adjacent stationary horizontal upper window frame member so that during the opening and closing movements of the window sash as the window swings about horizontal pivots, the junction is completely sealed at all times so as to prevent the ingress or the spattering in of rain and the like.

Another object of the invention resides in the provision of Weatherstripping, preferably metallic Weatherstripping, to seal the vertical sides of the enclosing window frame and the several vertically disposed window frames of the tier of awning-like window sashes.

Another object of the invention resides in providing a Weatherstripping construction for sealing the bottom of the top surface of the sill and the lower horizontal frame member of the lowermost frame member of the window sashes of the tier of window sashes.

Yet another object of the invention resides in the provision of flexible pads, preferably of felt, for insertion between the copper or other metal or flexible weatherstripping and the stationary frame member to which they are attached, whereby to maintain the resiliency of the Weatherstripping and/or also to assist in the sealing action.

Another object of the invention resides in the pro- 2 vision of the novel type of connection from the operating shaft that raises and lowers the tiers of window sashes and the crank handle on the inside of the window stool.

Another object of the invention resides in the provision of various improvements in the extension shaft and the manner in which its inner end is adjustably mounted with respect to tile stools or to elevated stiles located well above the floor and for connection to an elongated crank member.

Yet another object of the invention is to provide means for preventing the over-swinging of the crank arm for actuating the raising and lowering linkage mechanism for the sash arms.

These and other objects of the invention will be ap-' parent from a perusal of the following specification, when taken in connection with the accompanying drawings, wherein:

Referring now to Figure 1, there is shown in perspective view a portion of a building having a window structure embodying the present invention. This window structure 1s conveniently called an awning type window, since the window is provided with a plurality of sashes 11 and 12 and 13 arranged in vertical series, one above the other, so that when closed the upper sash rail and the lower sash rail of ad acent sashes are in abutment, thus limiting the need for any mullions or other spacing bars between the sashes of adjacent windows. Figure 1 shows a window assembly having a single vertical tier of sashes which when opened in awning fashion appear as shown and have the advantage of permitting adequate air circulation since the awning effect deflects the air upwardly, thus constantly moving the warm air normally accumulating at the ceiling as in cases of other types of window constructions.

Each of the sashes 11, 12 and 13 is hingedly secured adjacent the top sash rail to the outer window casing, and in the present invention a suitable operating mechanism sectional view taken on the line perspective view of the weather- 3 is mountedon-the inside of the window easing between the side jambs and between the window and the window sill so as to eliminate the need of expensive structures which would be required where the operating member :is fmounted within .the vertical side members or stiles. .Thiszmanner of structure permits a window of this type to be'inserted in the ordinary window opening.

:Referring now to Figures 2, 3, 4'and 5, it will be'seen that the upper'window sash 11.is hingedly supported by a pair of hinges, generally designated by the numeral 19, .which servetohinge each uppermostfsashto the side jambs of the window frame, as hereinafter set forth. This hinge construction .and:the manner:in which it is mounted .on the window. sash and side jambs of the stationary frame of thewindow'constitute-one'of the novel features of the present invention.

Inasmuchas the nomenclature of the many components of the Window1construction and frame construction are importanbtoa description'of' the invention and description of the hinge, it is thought appropriate first to describe the various component 'parts of the sashes and the window .frame members :in which the sashes are mounted. The sashes 11 to 13 are supported within a structure comprising a head jamb 21,"see Figures 4and 5, which may :beErabbeted at .22 to facilitate mounting a screen window without the use of special hardware. The frame also includes a sill 23 and interconnecting side jambs and side stops. Immediately above the upper sash rail of the window sash 71 1 there ispositioned a combined-head blind and head jamb 24b. This is a horizontally extending member and the upper sash member of the upper window 11 is arranged to abut this head blind 24b in weathertight, water-tight arrangement when the window is in closed position, as shown in Figure '4. This arrangement likewise permits the upper sash to be -pivotally swung outwardly as shown in Figure 16, away from this head blind 24b, while maintaining a waterproof and weatherproof seal as hereinafter disclosed.

The sill 23 is mounted in interlocked relation to a stiffener 26:against which is positioned a window stool 27 and the usual window apron28, see Figure 2.

The upper head jamb 21, see Figure 4-, is preferably recessed, at opposite ends, sufiiciently to receive the upper portions of sash arms 29. The construction of each of .these sash arms as an integral part of one of the hinge members of the sashes is one ofthe features of this invention. This integral hinge and sash arm is shown in detail in Figure 13, see also Figure 17. In general it comprises a single stamped metallic blank comprising an intermediate flat plate-like portion 29a which is bent at right angles to provide a normally disposed second fiat plate portion 29b provided with one or more attachment holes, as shown. The plate-like portion 2912 has integrally joined thereto a third plate-like portion 290 which is formed with an upward extension providing the sash arm generally designated by the numeral 29 having a suitable perforation 290. The opposite side of the plate-like portion 29a is provided with an integral offset portion 29d in turn terminating in a longitudinally extending, elongated, narrow plate-like portion 29c, the upper end of which is provided with a boss 29 formed with a per-- foration 29g. In addition, the central plate-like portion 29a is provided with a struckout tab 2% having a perforation 29:. Tab 2% lies substantially parallel to and spaced from extension 29b. Thus there is formed a single piece of stamped sheet metal having the foregoing shape and functional features now to be described.

This plate-like portion 29a as shown in Figure 17 embraces the outer side of the vertical frame member of the sash. Each window sash, such as sash 11, is provided with a wooden frame comprising the vertical window frame members 11a on opposite sides, and the top and bottom frame members 11b. These frame members receive the glass sash pane, as is well known in the art.

In a similar manner the sashes 12 and 13 comprise the c vertical sash frame members 12a and 13a and the horizontal or upper and lower sash frame members 12b and 13b. Figure 17 shows the manner in which the combined hinge and sash arm embraces each of the vertical mem bers 11a or 12a or 13a of the respective sashes 11, 12 and 13. Referring to Figure 17, the plate-like portion 29a is shown as lying in flat contact with one of the two outer side walls Ila-a of the vertical frame member 11:: of the window sash. The other plate-like portion 29b (see Fig. 13 also) lies in contact with the inner face 11b b of-the vertical frame member 110 andis fastened thereto by a screw as shown, and the portion 29c extends at right angles therefrom and upwardly, to form the sash bracket 29 as shown in Figure 17. On the opposite side of the plate-like portion 29a the struckout ear 29h engages the outer face 11c-c of the frame member 11a and is fastened thereto by a screw, as shown.

In addition, the integral elongated plate-like member 296, see Fig. 13, extends vertically upwardly parallel with the central 'plate-like'member 29a but is bent forwardly out of'the plane of the same. This portion, being perforated at 29g, forms a horizontal bearing for a pivot pin 29g, whereby thesashthrough the instrumentality of this pivotal hinge connection on each side may swing about the horizontal axis of this ipivotpin 29g for raising and lowering movement. For the upper sashes of each series the complemental hinge members are different from the complemental hinge members of the lower sashes and this forms an additional importantpart'of the invention. Thus, for instance, referring to Figures 12 to 15 inclusive, each complemental hinge 'member for the upper sashes comprises a stationary channel-shaped sheet metal blank -29j, see Fig. 13, having an integral rightangle plate-like portion 29k and an opposed andparallel plate-like portion 291 which forms a guideway. The plate-like portion 29k is provided with fastening openings 29m by which this portion is fastened to one of the parallel, front vertical members 24a of the window frame on each side thereof, see Fig. '12. The central plate of this supplemental hinge Iplate (see Fig. 13) is provided with an elongated slot .2911 which receives a pin 290, see Figs. 14 and 15, on a vertical narrow bar 29p. The upper portion of this bar supports the pivot pin 29g hereinbefore described.

As shown in Figure 14, the pivot pin 29g comprises a headed'shank portion 292 and a shoulder portion 29s and a reduced neck portion 29t and a riveted head 2911. The riveted'portion 291: fastens'the pin to the bar 29p and the shoulder portion 29s forms a bearing surface against the slotted member 29 see Fig. 13. A fiber washer 291' is interposed between the surface of the bracket plate 29 and the inner surface of the portion 292 of the hinge. This fiber washer 29r permits a loose fitting construction so that the lower portion of the bar 29p may be moved laterally away from the slot to disengage the pin 290 from the slot as shown in dotted lines in Figure 14 and full lines in Figure 15.

The release of the pm 290 from the bracket 29k permits the hinge pin 29g to move downwardly in the slot 29n, thereby permitting the upper sash to move downwardly the'length of the slot as the sash is swung outwardly about the pivot pin 29g. The upper sash thus assumes the lowered positionshown in Figure 12 so that a window washer may insert '-his hand over the top of the sash to clean the outside surface'of-the sash'pane from the inside of the room and thus eliminate the need for any special brushes and equipment to clean the outside of the upper window sash. Whenthe cleaning is completedthe sashes with the-hinge members are raised until the pin 290 has assumed a position opposite the slot when the bar 29p causes the pin 290 to snap back into the slot 29a. in

other words, the pin 290 will ride over the lower edge portion 29w of the slot and will'snap into position above that edge 29w. Figure 14 shows the pin 290 in position above the edge 29w to'lock the bar 29pto 'thestationary hinge member-29 and thereby holdthe associated hinge pin of the upper sash in its uppermost position.

With respect to the lower sas'hes'it is not necessary to have the same drop down to clean the outside of them because each one of these sashes can be reached from above when the next upper sash is in 'open position. Therefore the complemental hinge members for the lower sashes, each comprises a plate 79 having a right angle portion 83'provided with a perforated ear for the reception of a pivot pin 79a having an intermediate shoulder 79b and a reduced portion 790, see Fig. 20. In addition, there is a fiber washer 79d interposed between the fixed member of the hinge on the side frame of the window and the movable hinge member which is attached to the sash,jallshown in disassembled 'view in Figure 20. It is understood "that the member 79 of this hinge is attached to the front face-of the vertical member 2411 of the window frame. These hinge connections are on opposite sides of each sash.

The various sash arms 29, which are attached to the various window sashes 11 to 13, are interconnected by vertical link members 31. These link members are round rods flattened at their ends, the flattened end portions being perforated to receive pivot pins 31a which connect the link members to the upper sash arms 29. The upper rods 31, on opposite sides of the window, are connected to the upper sash arms 29 in the manner illustrated in Figure 4 and at each its opposite or lower end is connected to the adjacent, lower link member 31 by means of a pivot pin 31a that passes through the opening 29c in the associated sash arm 29. The bottom end of such lower rod 31 is connected to the top end of the next lower rod 31 and to the next lower sash arm 29 also by means of a pivot pin 31a.

Finally, the bottom end of the lowermost link rod 31 is attached by means of a pivotal pin 31b, Figure 5, to a crank arm 34. By suitable plates 32, secured by screws passing through the side frame 24a, there is supported a rock shaft 33 which carries at each end one of these crank arms 34. The rock shaft 33 is provided at one end with a gear 36 which meshes with a worm gear 37 mounted on a shaft 38. This shaft 38 has at its right hand end, as shown in Figure 4, a socket to accommodate a hexagonal extension which extends beyond the structure of the window and has at its end a crank 39, see Fig. 2. Thus by rotating the crank through the before described connections the window sashes are raised and lowered, the bottom portion of each window sash closing upon the top rail of the next lower sash. In addition, a plate 32a, Figures 4, and 21, is fixed to the supporting plate 32 and is provided with a notch 32b which limits the movement of the gear 36 by means of a pin 36a fixed on the outer face of the gear 36. The pin 36:: enters the slot 32b to contact the back wall 320 of the slot and prevent the gear 36 from revolving more than a predetermined angular extent in a clockwise direction. This is to prevent the turning of the crank 39 beyond a predetermined point in the window opening operation so as not to jam the sashes into the frame, thereby causing undue stress upon the hinges and other parts of the mechanism.

It will thus be seen that the operating mechanism is readily accessible from the inside of the building and yet is hidden to a considerable degree by means of an inside window screen 41, the upper rail of which fits into the plowed or rabbeted recess 22 of the head jamb. The head jamb 21 is provided with a cut out portion 21a, shown in Figure 4 to accommodate the upper portion of the hinge member 29 when the sash is in closed position. This cut out portion 21a is closed at the top to prevent any dirt or dust from entering into the structure by this means. The bottom of the screen 41 rests upon the stiffener 26 which is retained by the window stool 27. The side members of the screen 41 engage side stops 55 shown in Figure 6.

Weatherstripping means is provided for preventing the ingress of moisture and rain and wind when the sashes are in open position and also when they are in closed position. A head strip 44, Figures 2, 4, 11, 12 and 16, is attached to the upper window frame member 2412. This head strip holds in place and is provided with a downwardly projecting copper Weatherstripping member 44a. This Weatherstripping projects downwardly well below the upper surface of the upper window sash frame member 11b. The lower end of this copper weatherstripping is, of course, flexible and flexibly engages the outer face of this upper window frame member 11b of the sash whereby when the sash is in the closed position shown in Figure 4 or when it is in the open position shown in Figure 16 it overlaps and contactingly seals against this flexible upper sash rail or member 11!). This copper strip extends the entire width of the upper sash and thus forms an effective seal so that, as shown in Figure 16, if heavy rains strike the upper frame and tend to splash, it will be stopped effectively so that it cannot enter into the room above the open upper sash 11 even when the sashes are in open position. There is no necessity for any such Weatherstripping on the lower sashes because each sash prevents the rain from entering below it.

In addition, side Weatherstripping members are provided, see Figures 6 and 18, to make a weathertight seal when the sashes are closed. These side copper Weatherstripping members 4417 are hold by means of -of the hinge.

tacks or other fasteners to the side jambs 55 shown in Figure 6 and they project beyond the inner walls of these side jambs and beyond the vertical frame members 24a to engage the rear faces of the window sash members 121: and 12a.

In addition, Weatherstripping is provided for the top of each of those sashes 12 and 13 which are below the upper window sash 11. To this end, aflixed to the upper horizontal window sash members 1212 and 13b of sashes 12 and 13 are horizontal elongated copper strips 44c, Figures 4 and 18, that are attached as at 44d. Felt pads 44e are provided in the corners and underlie the extreme ends of this Weatherstripping in order to give it resiliency and prevent it from being bent or collapsed flat onto the upper wall of the sash members 12b and 13b of the sashes 12 and 13. These felt pads project outwardly beyond the free resilient edge of the strip and engage the vertical weatherstrips 44b whereby to provide seals at these points.

An additional copper or other flexible Weatherstrip 44;, Figure 16, is atfixed to the underside of the head piece 24b and at each end it is provided with an underlying, resilient pad (not shown) similar to the pad 44c, which projects therebeyond to engage the side Walls of the vertical window frames and also to engage the top ends of the vertical weatherstrips to provide similar sealing functions and to prevent the upper horizontal Weatherstripping members 44 from being packed down tightly when the Windows are closed from time to time.

In addition, a lowermost copper sealing strip 44h, Figure 4, is attached to the sill as at 441' and runs the length of the sill. The free end of this strip extends normally upwardly and resiliently engages the lower side of the frame member 13b throughout its length, each one thus forming a seal at this point for the lower window sash when in closed position.

If desired, a storm sash complete Window pane can be substituted for the screen 41 and mounted in the same manner as the screen itself, as shown.

Figure 7 shows a modified form of stool detail for tile construction. In using this tile stool construction means must be provided for accommodating the operating handle for the windows to the width of the tile stool construction. To this end therefore the end of the shaft 38 is provided with an extension thimble 381) that has a socket to accommodate a crank handle 39. This crank handle 39 extends through an adjustable sleeve connection consisting of the plate 38c afiixed to the window stool stiffener 26 by screws 2%. The plate 38c carries an externally threaded sleeve 38d which threadedly engages an outer sleeve member 38:2 fastened to a plate 38 which in turn is perforated to fasten to the inside wall below the stool and into a wooden frame member 38g. By turning the plate 33 and threadedly moving it back and forth on the threaded sleeve 38d, an adjustable position can be arrived at at which the plate 38 may finally be attached to the frame member 38g and held in permanently aflixed position.

Figure 9 shows a construction wherein the crank operating means is positioned at an upper elevation well above the floor so that it cannot be reached by the hand. In this case the outer end of the extension shaft is mounted in a substantially U-shaped bracket 38m which supports a pair of bevel gears 38n and 380, the gear 38mv being connected to a connecting sleeve 38;) by set screw 38g. This interconnecting sleeve also connects with the elongated extension shaft 40. The bevel gear 380 has attached to its stub shaft a ring member 381' for engagement with a hook 38s on an extension rod or crank handle 381, see Fig. 10. This crank handle may be of considerable length for operating the windows Hvhcn the same are at a considerable elevation above the oor.

As shown in Figures 6, 11 and 12, a preferably rounded head thumb tack 50 is inserted into the inner opposed walls of the vertical window frame members 24a to be engaged by the adjacent face of the plate-like portion 29a of the movable hinge member, as shown particularly in Figure 17, so as to permit accurate spacing between these two surfaces during the opening and closing movements of the window and also to form a smooth surface bearing against the movable portion 290 It is understood that these thumb tacks are on each side of the Window sash and operate as above described. As shown in Figure 12, to permit the lowering of the .upper sash for cleaning purposes, the pivot connectionso'f the upper rods 31 to the upper sash arms 29 must be released. This 'may be accomplished by first removing the snap fasteners 31d from the pins 31a at the upper rods 31, one only of these snap fasteners 31d being shown in Fig. 12. The snap fastener 31!! is removed from its associated pin 31a by operating it out of an annular groove 31s in which it is positioned when attaching the rod 31 to the associated sash arm 29. After the snap fasteners 31d have been removed, the pins 290 are removed from'the slots in the stationary hinge members 29 It will thus be seen that the hinge member is constructed in a manner such that the movable hinge memher is enabled to support the vertical side frames of the window sashes on opposite sides thereof, with a sort of clamping action since the spaced walls of this hinge member engage opposite sides of the vertical sash frame 11a, as shown in Figure 17, the screws shown merely serving to hold the hinge member in place instead of supporting the entire hinge. Furthermore, it must be evident that by forming the movable hinge member and sash arm in one piece considerable economy and ruggedness of structure are provided.

In addition, the construction of the upper hinge provides a very simple manner of permitting the upper sash pane to be cleaned from the inside, without the use of special brushes.

By reason of the manner of arranging the Weatherstripping, moisture and rain are prevented from entering the window through the various joints, also making the entire structure adaptable to climates where the weather is more severe.

It is apparent that many widely different embodiments of this invention may be made without departing from the spirit and scope thereof, and therefore it is not intended to be limited except as indicated in the appended claims.
