Among the principal objects of the present invention is to provide a double-hung sliding sash Window construction wherein provision is had for readily swinging either or both of the sashes inwardly of the window frame so as to render both sides of the glass panes of the window sashes accessible from within the room for cleaning.
A further object of the present invention is to provide a window construction of the above type wherein either or both of the sliding sashes may not only be swung inwardly of the window frame but may also be quick-detachably removed therefrom with a minimum of effort and without requiring any disorganization of the sash-balancing mechanism, the latter remaining intactwithin the Vertical boxes provided therefor in opposite sides of the window frame, the arrangement being such that either one of the sashes may be,
entirely removed from the window frame independently of the other sash.
A still further object of the invention is, to provide a window construction having double-hung sliding sashes which are adapted to be swung inwardly of the window fram to provide access from the room side thereof to a storm window or screen assembly Which is fitted upon the outer side of the frame, this assembly being provided with a hinged frame adapted to be fitted with screening or glass, this hinged frame being also swingable inwardly of the window frame to afford access thereto for cleaning both sides thereof from the inner or room side of the window frame.
A further important object of the present invention is the provision of means which are automatically operative when either of the sashes is swung inwardly of the frame preliminarily to removal of the sash from said frame to lock the sash-balancing mechanisms extending vertically along opposite edges of the sash to be removed against movement, these sash balancing mechanisms being maintained in such locked positions until such time that the sash is replaced within the frame to thereby automatically release the sash balancing mechanisms from their locked position.
Other objects and advantages of the invention and economies effected thereby will be apparent more fully hereinafter, it being understood that the invention consists substantially in the combination, construction, location and relative arrangement of parts, all as will appear more fully in the detailed description which follows, as shown in the accompanying drawings, and as finally pointed out in the appended claims.

Figure 19 is a view taken on the line l9-l9 of Figure 1'7.
Referring now to the drawings and more particularly to Figures 1 to 17 thereof, it will be observed that the window frame of the present invention which may be formed of wood or metal and of any heighth and width as may be desired,
is generally of rectangular form having a bottom sill member ID, a top header member H and a pair of opposed vertical stiles l2 and I3, all of which are joined together in any suitable man- As appears most clearly in Figures 5 to 7, the inner faces of the vertical stiles I2 and i3 are correspondingly shaped as shown to provide laterally spaced runways which are respectively adapted to slidably receive the sliding sashes I4 and I5 of the window. It will be noted particularly that the outer sliding sash M is of less width than the inner sash IS, the purpose of which will appear hereinafter. Provided in each of the stiles l2 and I3 are vertical boxes IS- l6 and l'I-ll in which are disposed the sash balancing mechanisms of the type preferably employing a coarse pitch screw I8 which moves axially into and out of an elongated tube immovably fixed in the upper part of the frame against the action of a spirally wound sash balancing spring encased within said tube. Inasmuch as this type of sash balancing mechanism is of conventional construction and quite generally used in the art, no further description thereof need be given here except to point out that in order to adapt this type of sash balancing mechanism to the present invention, the lower end of .the screw I8 is provided with a hook-shaped extremity I9 to serve as an anchor for securing said screw |8 to the detent mechanism, designated generally by the reference numeral 20 (see Figures 17 and 18) for retaining the sash balancing mechanisms in fully extended condition when the sash associated therewith is removed from the window frame.
As appears most clearly in Figures to 7, inclusive, each of the sashes I4 and I5 are rab-, beted along their outer edges (as at 2| and 22) and the frame is correspondingly shouldered to snugly fit said rabbet edges in order to provide an adequate weather-tight fit between each sash and the frame when the sashes are in closed position. The outer sash I4 is normally retained against lateral displacement out of the normal plane of its sliding movement by means of vertically extending angle members 23-24, while the inner sash 5 is similarly retained against lateral displacement out of its normal plane of sliding movement by vertically extending angle members 2526. These members 23 to 26 are of angular cross-section and are secured by means of screws to the inner faces of the opposed vertical stiles I2 and I3 in such manner that the flanges 23a-24a lie in a common vertical plane and serve as stop beads for the outer sash l4, while the flanges 25a-26a serve as stop beads for the inner sash l5.
As appears most clearly in Figures Band 9, the member 23 which serves as one of the stop beads for the outer sash l4 extends throughout substantially the entire length of the window frame and is provided at approximately its central point and at a point adjacent its lower end with axially aligned pivot pins 21 and 28. The member 26, which serves as one of the stop beads for the inner sash l5, likewise extends the full length of the window frame and is also provided with a pair of axially aligned pivot pins 29 and 3 0. It will be observed, however, that the members'23 and 26, each of which is provided with the abovementioned pivot pins, are respectively secured to opposite vertical stiles of the window frame.
The stop bead 24, which coacts with the stop bead 23 to retain the outer sash in normal sliding position, also extends lengthwise of the sash but it is sectionalized, the lower section 3| thereof (see Figure being removable from the sash. Similarly, the stop bead 25, which coacts with the stop bead 26 to retain the inner sash in position, is also sectionalized' to permit its lower section 32 (see Figure 8) to be removed. It will be observed that the removable sections 3| and 32 of the stop beads 24 and 25 are each of a length greater than the overall length of either sash. As appears most clearly in Figures 11 to 16, inclusive, the upper extremity of the removable section 32 of the outer stop bead and the lower extremity of the fixed upper section of said stop head are complementally formed, as at 33 and 34, to form a flush joint 35 (see Figure when stile. To retain the fixed and removable sections of the stop bead 25 in position, a headed pin 38 is employed which projects commonly through the overlapping portions of the bead sections to maintain them in their assembled relation shown in Figures 8, 15 and 16. The overlapping portions of these sections are preferably cut at a diagonal as illustrated in order to facilitate removal of the lower removable section 32 by rotating the same in the direction indicated by the arrow in Figure 15 about the screw 31 as an axis. It will be understood, of course, that the stop bead 22 is formed in the same manner as the stop bead 25, that is, it is also sectionalized to provide for the ready removal of the lower section 3| thereof upon withdrawing the retaining pin 39, thereby permitting the slotted lower extremity 40 thereof to be disengaged from the retaining screw 4| (see Figure 10) The outer sash I4 is fitted along one edge thereof with vertically spaced female hinge elements 42 and 43 adapted respectively to engage with the male hinge pins 21 and 28 when said outer sash is moved into its lowermost position, as shown in Figure 9. Similarly, the inner sash I5 is provided along one edge thereof with a pair of vertically spaced female hinge elements 44 and 45 which are adapted respectively to engage the hinge pins 29 and 30 when said inner sash is lowered into the position shown in Figure 10.
From the foregoing, it will be observed that when either or both of the sashes l4 and I5 are lowered into their respective positions shown in FigurelO they may be swung inwardly of the frame about their respective pivots, assuming, of course, that the removable sections 3| and 32 of the stop beads respectively engaging the free or unpivoted edges of the sashes are removed from the frame. Thus, if it is desired to swing the inner sash 5 inwardly, it is merely necessary to lower the sash so as to effect a pivotal connection with the pivot pins 29 and 30 and then remove the lower section 32 of the stop bead 25. The inner sash may then be swung inwardly of the room, as illustrated in Figure 6. Similarly, in order to swing the outer sash inwardly of the room, as shown in Figure 7, the said sash I4 is first lowered so as to effect a pivotal connection with the pivot pins 21-2B and the lower section 3| of the stop bead 24 is then removed, thereby permitting the sash to be swung inwardly as shown.
The pivotal connections between each sash and the window frame are such as to permit the sashes to be readily removed bodily from the frame, it being merely necessary to effect this to lift each sash sufliciently to disengage the female hinge elements (which are fixed to the sashes) from the upwardly projecting pivot studs (which are fixed to the opposed vertical stiles of the frame). This operation of bodily removing each sash from its frame is, of course, performed when the sash is in its lower position, in which case the sash-balancing mechanisms heretofore mentioned are drawn into their most extended condition. By so bodily removing the sash from the window frame, it is, of course, necessary to effect its disengagement from the sash-balancing mechanisms and this is accomplished by the means now to be described.
As has been previously mentioned, each of the sash-balancing mechanisms is disposed for operation within a vertically extending box provided in the vertical stile of the frame. Secured to the hook-shaped lower extremity of the screw l8 of each sash balancing mechanism is a block 50 which snugly fits within a channel forming part of the sash-balancing mechanism box. This channel extends throughout substantially the lower half of the vertical stile of the frame and is in vertical continuation of the fully enclosed box within which is housed the upper portions of the sash-balancing mechanisms. The channels 5| are each disposed so that the mouths thereof present toward each other, the inner faces of the stiles l2 and I3 being respectively transversely slotted, as at 52 and 53, to provide communicating passages with the channels 5| located in said stiles. The block 50 which is secured to the screw I8 of each sash-balancing mechanism by means of the transverse pin 54 is provided with a detent 55 pivoted to the outer face of the block by means of a pivot pin or screw 56, this detent being spring-biased by a tension spring 51 which tends constantly to rotate the detent, when viewed as in Figure 17, in counter-clockwise direction. The block 50 is provided with a transverse slot 58 immediately above its pivot 56 and with a vertically extending slot 59 in its lower extremity. The detent 55 is itself shaped, as is best shown in Figure 17, to provide a hook-shaped lower extremity 60. It will be understood, of course, that each of the sash-balancing mechanisms is equipped with a block and spring-biased detent of the type shown in Figure 17. v
Secured in the base wall of each of the channels 5| within which the block 56 is vertically slidable is a detaining screw 6| (see Figure 17) with which is engageable the hook-shaped lower extremity 60 of the detent 55. This detaining screw 6| is so located that when the block 6| is shifted into its lowermost position, the shank of the screw is received within the slot 59 of the block. As appears most clearly in Figures 1 to 7,
inclusive, each of the sashes is provided at opposite sides and adjacent the bottoms thereof with oppositely extending pins 62 which serve as the means for automatically effecting engage- -ment and disengagement of the detents 55 to and from the detaining pins 6|.
In the operation of the detaining means just described, it will be assumed that the inner sash I5 is in its normal sliding position as shown in Figures 1, 5 and 8. In this position of the sash,
the oppositely extending pins 6262 thereof will each be in such engagement with the detents 55 that the-latter will each be forced into the dotted line position shown in Figure 17. In this dotted line position, the detent is disengaged from the detaining screw 6| and the sash is then free to be moved upwardly or downwardly within the limits of the frame, the blocks 50 which move 7 with the sash serving as the means for connecting the sash to the sash-balancing screws Hi. In other words, the oppositely extending pins 62 being disposed within the slots 58 of the blocks 50, cause the latter to move with the sash and inasmuch as the blocks are in turn connected to the sash-balancing screws, the latter are operative to balance the weight of the sash in whatever position it may be located.
However, when the sash I5 is lowered into its lowermost position so that its hinge elements are in engagement with the pivot studs of the frame so as to enable the sash to be swung inwardly of the room, when the sash is so swung the detaining pins 6| inwardly the oppositely extending pins 62 thereof move out of the slots 58 in the blocks 50 in consequence of which the detents 55 swing into the full-line position shown in Figure 1'7 under the influence of their tension springs 51. When this action takes place, the blocks 50 are, of course, in their lowermost positions with the detaining screws 6| respectively located at the upper end of the slots 59 in these blocks. It will be apparent then that when the detents are no longer influenced by the pins 62 and swing into the full-line position (Figure 17) under the influence of their tension springs 51, the hook-shaped extremities .60 of these detents respectively engage and so hold the sashbalancing mechanism against retraction, that is, in their fully extended condition. In this condition of the device, the windows may be bodily removed without further disturbing the sashbalancing mechanisms.
To restore the sash-balancing mechanisms into operative condition, it is merely necessary to swing the sash back into its normal sliding position within the frame whereupon the pins 62 thereof reenter the slots 58 of the connecting blocks 50, and engage and shift the detents 55 of said blocks out of engagement with the detaining screws 6|, the sash-balancing mechanisms storm sash assembly which may be fitted within the outer side of the window frame. In accordance with the present invention, the window frame is so fitted with an exterior assembly 63 which may be either in the form of a screen assembly, as shown in Figures 8 and 9, or a storm sash assembly as' shown in Figure 10. This as-, sembly 63 generally comprises a main frame 64 the upper edge of which is detachably hinged, as at 65, to the'wlndow frame in such manner as to permit this frame to be swung outwardly about its pivotal connections in the direction of the arrows shown in Figures 8 to 10. Normally, the frame 64 is secured in the flush vertical position within the frame, as shown in these figures, by any suitable locking means 66, access to which is had from the inner side of the window frame when the sashes are either swung open, as shown in Figure 7, or are both vertically raised to'a height sufficient for that purpose.
Fitted within the hinged frame is an auxiliary frame 61, one vertical edge of which is hinged, as at 68-68, to permit this auxiliary frame to be swung inwardly of its. supporting frame into the dotted line position shown in Figure 7. This inward swinging of this frame 61 is, of course, effected only when the sashes I4,
and I5 are both swung into their, open position shown in Figure 7. The hinged auxiliary frame 61 may be fitted with a screen 68 (see Figures 8 and 9) or with a glass pane 69 (see Figure 10), in which latter event the assembly 63 serves as a storm sash. To facilitate inward swinging of, the auxiliary hinged frame 61, it is provided with a suitable knob 10 adjacent its free edge. Also, in order to maintain the auxiliary frame 61 in locked position, suitable. locking devices 1 l-1| may be employed which serve to lock the frame 6'! in flush relation with respect to its supporting frame 64. It is, of course, preferable to provide a pair of the auxiliary frames 61 for each of the hinged main frames 64 and to respectively fit them with screening and glass so that either one may be replaced by the other depending on whether the window frame is to be equipped with screen or storm sash.
By swinging the window sashes M and H5 in-' wardly as shown in Figure 7, not only may the operation of mounting the interchangeable screen or storm sashunits within the frame M be performed from within the room, but also the operation of mounting the frame 64 upon the window frame may likewise be performed from within the room.
It will be understood, of course, that the invention is susceptible of various changes and modifications from time to time without departing from the real spirit or general principles thereof and it is accordingly intended to claim the same broadly, as well as specifically, as in dicated by the appended claims.
