10 Claims. (01. err-50y This invention relates to improvements in windows and more particularly windows of the double-hung sash type.

Such windows are universally popular despite the fact that they have a number of inherent disadvantages. When the sashes are movedinto positions with one directly behind the other, the relation which opens the window as wide as possible, one half of the open area of the window frame is blocked by the sashes. This seriously affects the ventilation in warm weather, often making it difficult to cool 01? bed rooms on Summer evenings even after the air out of doors has become comfortably cool.

Washing the outside of double-hung sash win. dows is diflicult when attempted from inside the building. First floor windows can sometimes be reached from the ground, but in the 'absence'of a porch roof, balcony, or other standing room, windows above the first floor can be washed efficiently only by climbing through the: window frame and sitting or standing on the sill outside the window. For most housewives this is too strenuous and dangerous, and the result is that upstairs windows are'either left dirty or the washing done by a workman who must be paid for the job.

These difiiculties are overcome by casement windows, but'casement windows have disadvantages of their own. They are much more likely to leak and are difficult to weather strip effecvtively. If a casement window swings inwardly it takes up space in the room, and furniture must be located so as to leave the window an unobstructed arc in which to swing. If the window is hinged so as to open toward the outside it presents a screening problem. Outside screens cannot be used, andan inside screen must not block access to the window. An inside screen that swings may be just as objectionable as an inwardly swinging casement window.

A sliding sash window with the weight of the sash counterbalanced will remain in any position to which it is moved, but a casement window must be hooked or clamped to insure that itwill not blow open or shut. i

It has long been recognized that the ideal window would be one having sashes capable of both sliding and swinging movement. The desideratum has been a windown having all of the advantages of both sliding sash and casement windows. Many attempts have been made in the past to construct such a window, but so far as we are aware all of these attempts have been impractical because they require special and expensive frame construction.

It is an object of this invention to provide an improved window construction which obtains both sliding and swinging movement of the sashes. A more specific object of the invention. is to provide such a construction which can be conveniently and economically applied toexisting double-hung sash windows of the type most commonly used in wooden buildings. The invention can be applied to existingwin'dows, and its simplicity makes new windows. in which it is embodied reasonable in cost in comparison with ordinary sliding sash windows.

Windows made in accordance with this invention are easily operated, can be moved up and down when swung open as well as when confined by the stile runways, and are counter-balanced effectively in all positions.

Other objects, features, and advantages of the invention-appear or will be pointed out as the specification proceeds.

, Inthe accompanying drawings, forming part hereof:

Fig. 1 is a perspective view of a window embodying the invention, with the sashes swung open.

Fig. 2- is a perspective view, partly broken away, of the window shown in Fig. 1, but with the sashes in the positions occupied when the window is closed.

Fig. 3 is an enlarged sectionalview taken on the line 3-3 of Fig. 2, but with the lower sash raised.

the window shown in Figs. 1 and 2.

Figure 9 is a sectional view similar to Figure 3 but taken on the line 9-9 of Figure 2, and with the upper sash lowered.

. The window includes a frame Ill of conventional design. An upper sash I I, has a joint near its left edge com-prising hinges [3 connecting the main bodyof the sash with an outer shoe 15 which has the same height and thickness as the main body ofthe. sash so that when the sash is closed, (i. e. in position toslide up and down in the frame) the outer shoe is, in effect, a con- .tinuation of the main body of the sash as shown in Fig. 5. A weather strip ll attached to the L outer shoe insures against any leakage of air between the shoe l5 and the other part of the sash, but the window can be made without the weather strip if absolute tightness against infiltration is not essential.

The outer shoe I5 is recessed to fit over a track l9 which is fastened to the pulley stile 20 of the frame by countersunk screws 2| (Fig. 3) The track I9 extends for substantially the full height of the pulley stile.

The recess in the outer shoe l5 has a depth slightly less than the height of the track so that the shoe bears against the track and there is a small clearance between the shoe and the pulley stile.

An inner shoe 23 fits loosely within the track I!) and has a ridge 24 which extends through a slot 26 in the track and contacts with the outer shoe 5. The inner and outer shoes are fastened together by screws 25 which connect the hinge Hi to the outer shoe and thread into the inner shoe. The width of the ridge 24 is slightly less than the width of the slot 26. The height of the ridge 24 is a little greater than the height of the side walls of the slot so that there is clearance for the edge portions of the track below the inner and outer shoes. The ridge 24 is preferably integral with the inner shoe 23 but this is not essential and shims can be used in place of an integral ridge.

The outer shoe |5 slides in the channel or stile runway between the blind stop 29 and parting strip 30 in the same manner as the upper sash of any conventional double hung sash window. The sash H is counterbalanced by a weight 32 connected to the sash by a cable 33 which passes over a pulley 34 and connects with a hook 36 at the top of the inner shoe 23 as shown in Fig. 6. Spring balances which are used in place of weights in some modern houses, may, of course, be used in the same way with this invention. The counter-balancing of this invention is just as effective when the sashes are swung open as casements, as when they slide up and down as ordinary sashes.

A second inner shoe 38, shown in Figs. 5 and 7, is connected to the outer shoe l5 at the level of the lower hinge l3. The construction and attachment of the inner shoe 38 is the same as that already described for the inner shoe 23, except that there is no hook 36 because no counter-weight cord is attached to the lower inner shoe 38.

The window has a lower sash 4| which includes an outer shoe 42 (Fig. 2) connected to the main body portion of the sash by hinges 43 near the right edge of the sash. The lower sash has an inner shoe, track, counterweight and other construction similar to the upper sash already described, but the track for the lower sash is located in the stile runway in front of the parting strip 30, that being the runway in which the lower sashes of conventional windows slide.

The upright edges of the sashes I I and 4| which are remote from their hinged connections with the shoes 5 and 42 slide in the stile runways behind and in front of the parting strip 30 in the usual way. Weather stripping 41 is used in these runways in the illustrated embodiment of the invention. The sashes slide up and down in the frame, the hinges 3 of the upper sash being short enough to pass the lower sash. The window can be locked closed by the usual window lock 49.

The conventional window frame for double hung sash has a removable portion of the pulley stile through which access may be had to the weight pocket of the frame. In applying this invention to a conventional window, the removable portion of the pulley stile is taken out and the opening enlarged to make it somewhat longer than the height of the sash. While the pieces cut out of the stile can be connected with the removable portion to make the larger movable portion for this invention, it is more economical to save the labor by substituting a single piece of wood previously cut to fit the enlarged cut-out portion.

Fig. 5 shows a movable portion 5| of the pulley stile 20. This movable portion has stop plates 52 fastened to the upper and lower ends by screws 53. These stop plates 52 extend behind the fixed portions of the pulley stile 20 above and below the movable portion 5| and prevent the movable portion from moving out beyond the position shown in Fig. 5 in which the surfaces of the movable portion 5| are flush with the surfaces of the fixed part of the stile.

The track I9 is made in three sections as shown in Fig. 8, the lengths of the sections being such that the breaks 55 correspond with the upper and lower ends of the movable portion 5| of the pulley stile.

Springs 51 (Fig. 5) fastened to the fixed part of the pulley stile 20 by bolts 58 bear against the top plates 52 and hold the movable portion 5| of the pulley stile in its normal forward position shown in Fig. 5.

When the outer shoe I5 is on that section of the track l9 which is fastened to the movable portion 5| of the pulley stile the sash I can be pushed to the left, against the tension of the springs 51, far enough to make its edge which is remote from the hinges |3 come out of the stile runway in which it slides. The sash is then free to swing on its hinges l3.

It is necessary for the parting strip 30 to move back with the movable portion of the pulley stile,

otherwise the hinge l3 (see Figure 3) would strike the parting strip and prevent the sash from moving back far enough to clear the guide channel on the other side of the window. The movable portion of the pulley stile on the left hand side of the frame permits the sash II to move far enough to the left so that its free swinging edge clears the hinge edge of sash 4|, when that sash is swung open, as shown in Figure 1.

The strength of the springs 51 is such that the sash can be easily pushed laterally to clear the stile runway on the side away from the hinges when it is to be swung open in casement fashion, but the springs 51 are strong enough to hold the movable portion 5| of the pulley stile in the position shown in Fig. 5 during the ordinary up and down sliding movement of the sash. Best results are obtained by having the lower spring 51 under somewhat greater tension than the upper spring because the sash is counterbalanced on the hinged side only and that creates a tendency for the entire movable assembly, when in the position shown in Fig. 5, to rotate clockwise about the upper end of the top stop plate 52 as a center,

and such movement is prevented by the lower spring 51. Heavier sashes require stronger springs.

The lower sash 4| has a movable portion 60 of the pulley stile behind the track on which' the lower sash slides. This movable portion 60 is similar in construction to the portion 5| already described but is, of course, a portion of the forward runway instead of the rearward runway. It is a feature of the construction that the movable portions and Bil-ofthe pulley stiles for both sashes are at the same height above the window sill 62." It is much more convenient to push the sashes laterally to clear the stile runways and swing the sashes open when the sashes in. the lower part of the frame, In"fact a short person standing on the floor might not be able to push a sash laterally if the movement had to be made with the sash near the top of the frame and almost out of reach.

It is anothe r feature of the invention that the movable portions 5| of the pulley stiles are longer than the heights of the sashes. This makes it unnecessary tolocate the sash accurately before pushing it laterally preparatory to swinging it open.

The invention is not limited to wooden frames or to the embodiment illustrated in the drawings. Various changes and modifications can be madewithout departing from the invention as defined in the claims.
