' sashes and the window frame.

fAnother object of the invention is to so form and mount the sash guiding means carried by the window frame that they will serve not only as guides for the sashes but also as shields for concealing counter-.balance connections.

Another object'of'the invention is to provide the counter-balance 'connections with sash engaging members which are adapted to be Vengaged with the strips constituting the sash guide and released' lfrom" the sashes when thesashes are shifted upwardly to the'top of the Window frame.

I'tfwill thus be seen that, when the window sashes are raised, they may be automatically released from theco'unterebalance connections and withdrawn from the window frame through the upper [portion thereof.

Another object of the inventionis to provide the" lower sash with keepers which are' movable from Van extended position in engagement with the V4'guides ofthe frame to a retracted position permitting removal of., the lower sash from the frame when the lower sash is in its raiseclpos "Another object ofthe invention is'to provide means forrlixniting'sliding movement of the two sashes inthe frame relative to each other. *"iThe invention is illustrated in the accompanying drawings, wherein: `Figure lisa perspective view of approximately one-half' of a window frame having the improved construction, Y Figure 2 is a perspective View of approximately one-half of the upper and lower sashes which are slidablyY received in the frame of Figure 1,

'I

The improved window has, upperand lower 30 sashes I andi.` which are mountedin a frame 3y having an vupperhead portion 4, a lower sill 5 and a weight box V6 extending vertically :at each side betweenthe sill and the head portion. vThe usual outer strip or blind strip 1 extends vertical- 35 lyv along the wall B of each weight box, and there has also been `provided the usual cross strip 9 secured against the under face of the head portion 4 between upper lends of the strip l.

In order to vcounter-balance the upper and 40 lower sashes "and permit them to be slid easily v in the frameand remain in an adjusted position', there have been provided the usual weightsA I0 to which the sash cords I I are tied. The sash cords are engaged about the usual guide pulleys I2 and 45 at their outer ends carry hooks I3 which project out of the grooves I4 and I5 in which the sash cords move with their hooked lower endsdisposed in position to engage the plates I 5 and ,I'I se.- cured against side edge faces of the two sashes I 50 and 2'at lower endsthereof. The grooves or channels I4 and I5l extend the full height of the window frame,e andthe hooks I3 slide freely .in theseA lgrooves vfrom a lowered `position close to thebottom of the, frame to araised position subsash at upper corners thereof.

stantially midway the height of the frame. Therefore, the two sashes may be slid vertically from a raised position to a lowered position and opened and closed in the usual manner. To each upper corner portion of the upper sash is secured a cleat I8, and since the cleats project inwardly from the upper sash, as shown in Figures 2 and 8, they will serve to engage the upper end of the lower sash and thus prevent the sashes from being slid in opposite directions beyondthe position in which they have their upper and lower ends substantially flush with each other. Metal weather stripping I9 is secured against the inner side face of the cross strip 9, and when the upper sash is in its raised or closed position, it engages the yieldable lip 20 of this weatherstripping to form an air-tight joint across the upper end of the upper sash. N e j l e In order to conceal the outer portions of the sash cords, there have been provided weather strip guards 2| and 22 which are formed of sheet metal bent as shown clearly in Figure'5 and in Figures 9 and 10. The `guard 22' has a main portion which is substantially U-shaped in cross section and along its outer side carries a lip 23 defining a channel 24. This guard 22 ts snugly within the upper half of the groove I with its outer surface iiush withthe surface of the wall 8, and when the lower sash is in its lowered or closed position, the sash cords for the lower sash will be entirely concealed from View. The channels 24 of the two guards 22 are intended to receive the guides or keepers carried by the lower Eachv of the upper corner portions of the lower sash is cut to form a pocket 25 in which a guide` or keeper 26 is pivotally mounted through the medium of a pin 2'I extending through its 4,lower end. Each keeper or guide is of substantially triangular outline with its apex disposed downwardly and the upper edge of the keeper is cut to provide a cam surface 2S leading'from a recess or seat 29 and merging into the outer side edge 30 of the keeper. A finger 3I extends upwardly at the inner side of the keeper and passes through a slot 32 formed in a resilient strip 33 extending transversely of the sash and secured upon the upper edge faces thereof by a screw 34. The upper end portion of this finger is bentlaterally, as shown in Figure 5, so that the finger may be easily grasped and the keeper swung about its pivot 2l to the extended position in which it engages in the groove or track 24 or to the retracted position within the pocket, as indicated by the dotted lines in Figure 7.- When `the two keepers are extended, they are held in this extended position by the free-end portion 35 of the spring strip which engages in the seat 29 and the lower sash will be held in its proper position for sliding movement from a lowered or closed posi,- tion to a raised position. In view of the fact that the end portion 35 is curvedlongitudinally of the spring strip 33 as shown in Figure 7, a camaction may be exerted by the curved portion 28 of the keeper andthe keeper easily shifted to its retracted position. When the keepers are in the retracted position, the lower sash may be shifted inwardly aftery being raised and bodily removed from the window frame.

A window guide 36 which is formed of sheet metal is provided and is secured against the wall 8 of the weight box along one side of the lower half of the groove I5. The window guide has an spaced relation to the upperend of said window guide, as shown in Figures 1 and 11, and this flange or lip extends into agroove 38 formed along the adjacent side of the lower sash at the outer face thereof. A metal closure strip 39 for the outer side of the recess 38 and a sealing strip or companion weather strip 40 are mounted in the recess 38 with their inner portions secured in a groove 4I by a suitable number of nails 42, and when the lower sash is in place, the flange 3'I of the guide 36 engages between the closure 39 and the weather stripping 40, as shown in Figure 6. Therefore, an air-tight joint will be provided at each side of the lower sash for the full height thereof when this sash is closed and air will be prevented from flowing through crevices between the window frame and sides or the lower sash. In View ofthe fact that the iiange 31 terminates in spaced relation to the upper end of the guide 36, this flange will be disposed below the lower edge of the lower sash when this lower sash is fully raised and the lower sash may be shifted inwardly out of the window frame. It should also be noted that, while the hook I3 of the sash cord will normally remain in engagement with the retainer plate I1 of the lower sash, the upper end portion of the lower sash may be tilted inwardly as it is raised and thus shifted upwardly tosuch a height that the hook of the sash cord will engage the lower end of the weather strip guard v22 and automatically release the window sash from the sash cord. This takes place at both sides of the window sash and the lower sash may then be bodily removed from the window frame with the hooks of its two sash cords remaining in engagement with lower ends of the two closure strips and their hooked ends projecting outwardly in position to again engage the plate I'I when the'lower sash is replaced and slidl downwardly. A guide 43 is secured against the wall 8 of the weight box at each side of the window frame to guide movement of the lower sash as it is inserted or removed.

The weather strip guard ,2| for the outer grooves I4 are each provided with a ange or lip 2|' along its outer side edge and thus provide each guard 2I with a flange or lip also serving as a weather strip. The weather strip 2| extends into a recess 44 formed in theouter face of the adjacent side portion of the upper sash and corresponding to the groove or recess 38 of the lower sash. An outer closure strip 45 is provided for each recess 44 and within each recess isr disposed a metal weather strip 46 corresponding to the weather strip 40, andv upon referring to Figure 5, it will be seen that the guide strip 2I' fits between the closure strip 45 and the weather strip 46 with said strip- 2I and'the weather strip 46 in close contacting engagement with each other to provide'a tight joint when the upper sash is in its raised or closed position and thus prevent air from flowing through crevices between side edges of the upper sash and side portions ,of the Window frame. A flange 41 formed along the closure strip 45 engages in a groove 48 formed in the outer face of the upper sash and when a suitable number of screws 49 are passed through the

strips

45 and 46 and into the sash the two strips will be firmly held in place and prevented from shifting out of their proper position. The upper end of each weather strip 46 is bent` away from the companion-closure strip 45, as shown at 50 in Figure 2, thus providing means for guiding the lower end ofthe weather strip 44into place between the-

strips

45 and 46.

When the upper sash is removed, it is shifted .downwardly after moving the cleat I3 to such a position that lower ends of the weather strips 2I move from between the

strips

45 and 46. The upper sash may then be tilted inwardly at its upper end and shifted upwardly to a position in which the hook I3 of its sash cord will engage lower ends of the guard 2l and automatically free the hook from the plate I6. Therefore, the sash cords of the upper sash will be released therefrom and the upper sash may be shifted inwardly for bodily removal from the window frame. When the upper sash is replaced and the cleat I3 again applied, it may be shifted downwardly to a lowered or opened position but it cannot be shifted downwardly a sucient distance to effect movement of the strip 2l' from between the

companion strips

45 and 46 as the cleat will engage the upper end of the lower sash and limit downward movement of the upper sash. It will thus be seen that the strips 2| will serve as guides for the upper sash as well as constituting weather stripping.

Having thus described the invention, what is claimed as new is:

1. In a window construction, a sash having vertically extending grooves at its opposite sides, a sash shftable vertically in said frame, counterbalances for said sash having' portions extending longitudinally in said grooves, closure strips for upper portions of said grooves, the closure'strips being formed with vertically extending channels, and retainers carried by said sash and movable from an extended position within the channels to a retracted position for freeing the said sash and permitting removal thereof from the frame.

2. In a window construction, a frame having side' portions formed with vertically extended grooves, a sash slidable vertically in `said frame,

counter-balancing means for said sash having members extending longitudinally in said grooves and adapted to be connected with adjacent side portions of said sash, and closure strips for upper portions of said grooves formed with longitudinally extending channels, keepers carried by said sash and movable from a retracted position to an extended position for engagement in said channels to guide vertical shifting of said sash, and means for yieldably resisting movement of the keepers in adjusted position.

3. In a window construction; a frame, upper and lower sashes slidable in said frame, strips extending longitudinally in said frame against opposite side portions thereof and each having a portion bent to form a longitudinally extending channel, upper corner portions of the lower sash being formed with pockets, keepers pivotally mounted in said pockets and eachbeing movable from a retracted position in the pocket to an extended position for engaging in the channelof the companion strip, spring strips secured upon the upper-edge face of the lower sash and extending across upper ends of the pockets with their free ends curved longitudinally and bearing upon upper edges of the keepers for yieldably resisting movement of the keepers to adjusted holds adapted tobe grasped when moving the keepers to adjusted position.
