Application February 15, 1949 ,1S erial Nb. 76,441 7 claims. (01. 1's0 27 This invention relates to window structures. An object of the invention is to reduceothe cost of manufacture of windows and'the cost: and labor involved in their installation.

Another object of the invention is to eliminate sticking or binding of a sliding sash in its guideways and at the same time preventing such a sliding sash from rattling. p

- An additional object of the invention is to eliminate the necessity of putting up and removing screens and of providing winter storage space for them.

In accordance with the invention the opening in the wall of a building which is to be closed by; a window is provided around its periphery with an outwardly extending weather strip. 1 A unitary window frame assemblage which may be constructed in a factory includes a sill, guideways for a sliding sash,housings for sash bal ance weights, a rotary support for a flexible member connecting the sliding sash to the weight, and a recess or chamber into which the sash may slide in the open position of the window. In contradistinction to the general practice of building the frame into the window opening, theframe in this invention is mounted on the outside of the wall adjacent the window opening. One end of the frame is hinged to the outside walland the other is connected to a clamp which may draw the window into a position tightly against the outwardly extending weather strip. a p v The clamp is releasable from the inside of the building to permit the frame to swing slightly about its hinge to carry the sliding sash out of contact with the outwardly extending weather strips so that the sash may be slidably moved toanewposition. Thereupon the clamp may be operatedto lock the sash in the new position.

The inventionmay best be understood by-reference to the following detailed description taken 'inconnection with the accompanying drawing in v :which:

Fig. ,1 is an elevation partly. in section of the outside ofawindow assemblage constructed in :accordance with the invention; f-

,2 is a horizontal section'along the plane indicatedby line 2.2 of Fig. 1 and viewedin the direction of the arrows; I

.i .Fig. 3 is a vertical section along the line-3-.-3 of Fig. 1 showing the window assemblage positioned against the outside wall of the build- ,"Fig. 4 is a vertical section similar to thatsof .Fig. 3 except that the window is shown in its ;released or unlocked position; 1,

5 ajvertical section along the line 5- 5 of Figlfl exceptthat the window is swungj to a,much greater degree to permit inspection; cleaning or repair; t I I l Fig. 6 is an elevationof. a metal framejs'ash whichconstitutes the sliding element in a win: dow according to this invention;

Fig. 7 is a vertical s'ection in the plane oflth'e line 1-1 of .the structure shown in FigQIBfand "Fig. 8is a horizontal section of the sash of Fig. 6 in the plane along the line 81-8.. Referring to Figs. 1 andZ, one embodiment of a window frame assemblage in accordance with the invention comprises two vertical U -shaped sash weight housings l0 connected at their upper ends by a horizontal roller' and screen housing If in which'roller I2 is enclosed and at their lower ends by a second horizontal housing I3 into which the sash M (shown in Fig 3 in half open position) may slide; The roller l2 is supported ateach end by'bearings l5 and is connected by flexible sash cords or straps [6 to the counterweights I! which serve to balance the weight of the sliding structure including sash I4. The unitary rectangular frame structure comprising vertical members In and horizontal members H and I3 is mounted by hinges 8 at its lower end on the outside of thewall l3 adja} cent a window opening so that the sash M in its normal closed positionwill overlie the entire window opening. Outer window stops 2,0 are attached to the frame members I0, [I and I3 and serve as outer guides for the sliding sash M. The lower outer stop for I purposes of Weatherpro ofi'ngand of appearance is fashioned in the shape of-awindow sill.

Extending aroundthe periphery of the window opening and attached to the wall I9 are inner stops 2| which like the outer stops 20 preferably are provided with weathrproofing imateria-l, such as felt orrubber, .on their surfaces adjacent the sash 14. By means of a clamping strap 22, illustrated and described more fullygin connection with succeeding figures, the-window frame may be drawn inwardlyswinging about seated the end of a clamping bolt 26 having an ofiset portion 21 mounted on a panel 28, This panel is attached to the wall l9 beneath the upper margin of the window opening and on the lower edge of the panel the upper inner stop 2| is mounted. Turning the knob 29 to the position shown in Fig. 3 causes the clamping bolt 26 to I operate as an eccentricto draw the frame inwardly and loci; it in that position. The frame may be released by rotation of the bolt 26 as shown in Fig. 4 sufliciently to free the sash l4 from the stops and permit sliding it to any desired p siti n whe e po h w ndow a ain may be clamped to hold the. sash tightly in the new position against; rattling or entrance of rain or wind. Should it be desired to swing th window frame farther out from the building. to permit inspection, cleaning, or repair the bolt 26 may be drawn vertically downward to disengage it from clamping strap, 22; and the window frame may then swing outwardly as shown in Fig. 5 to a, limiting position determinedby metallic holders 30 connected to the. housing H by a screw or other fastener. The'holders 30 slide through holes in panel 28 and as shown in Fig. 5 they consist oftwo pieces, that are hingedtogether by a bolt- In the releasedposition of the irameshown in Fig. 4 holders 3!), not shown in Fig. 4, are folded against panel 28 and serve as stops. for housing IL This insures that'in this position of. the frame thesash is free at both sides from engagement withv the inner weather strips 2] .t

v The sash M is connected by a flexible member 31 to the roller I2. In accordance with the invention the flexible member 3,! takes. the form i' a screen which serves, to hold the sides of the sash M at alltimesin a vertical position and which when the window sash hasslid down into the. lower housing l3 serves to cover the window opening andto exclude flying leaves and insects. v

The, sash is shown in two alternate forms. Figs. 3; 4 and5 illustrate a frameless sashcomprising solely a pane of glass or other translucent material. Figs; 6 and 7 illustrate a sash having a metal frame with atranslucent pane mounted therein. It will be noted, however; that both of" these-sashes are specially designed in accordance with the requirements of this invention and have the common feature ofasash structure presenting athickness that is substantiallyno' thicker than thethickness of the translucent panein the principal portion ofthe sash between its-upper and lower margins. This-enables the sash structure to becla-mpedtightly between the inner and oppositely placed outer stops of the window thus insuring-a weather tight seal. It also insures that the window structures mayslide into their respective housings through slots'of uniform width throughout without making theslots-wider than is necessary=for easy-action.

In the speciesof Figs. 3, 4- and 5l the-vsash I4 or cemented to the pane throughout the central portion and near the upper margin as shown in Fig. ,1 on the inside of the pane. It serves both to support the upper edge of the pane against excessive displacement in stormy weather when the sash is'partly open and also as a means for grasping the sash to open or close it.

The alternative window sash 33 of Figs. 6, 7 and 8 comprises a thin flat metallic upper horizontal'rail 34 of substantially the samethickness as the translucent pane 35 which it supports The pane 35 is carried at its lower margin by flanged central members 36' extending laterally from both sides of the lower horizontal rail of the sash frame and may be seated-on a leather packing strip 31 which fitsbetweenthe flanges. The upper margin-of the pane 35 isseated and clamped between two wooden strips 38 held tightly by the two central metal flang portions 39 of the upper horizontal rail 34. The-lower margin-of the supporting screen E0 is fastened by soldering or other means to a metal'strip 4| which may be fastened tothe upper'horizontal rail-3.4 of the sash by means of a few cotter pins 42. The two vertical side rails 63 of the sash have less thickness than the pane. In operation the lower flanges 36 will-always be positioned below the sill or lower outer step. In theclosed position of the window the upper flanges 39 will lie just belowthe upper coacting stops 20- and 21. At the sides the stops will'engage the name. This insures a tight weather'seal when the window is closed and clamped. HoweverQto prevent access of rain through the slots at' the ends of the upper flanges 39- it may be desirable to insert in these slots rubber gaskets 44. In this form the sash 33-" will require no supporting bar 32 since theupper flanges as'will'serve for its: functions.

It readily will be appreciated from'theforegoing explanation that the window: structure of thisinventioxi does not require to be built into the wall; opening or tube accurately-fitted toit but that it readily may be applied to the window opening irrespective of the fact that there may be considerable deviation of the window openin from ideal dimensions. It also will be understood that installation of. a window according to theinvention may be-made after the masonry or carpentry work. has been fully completed since it. isnecessary only to. apply the window-frame to the outside of the wall and not to build it. into the opening; Sliding: of 'windowsashes inpclose fitting. guides with: consequent stickingand squeaking has been. wholly eliminated. Most important of all when the window. is in closed position there are no opportunities for airleaks or any necessity of special weather'stripping'to overcome-such leaks; The window sash is'held firmly. thus. eliminating rattling. Moreover the structure is such: that in rapid change of'weather one may have either a closed window with vision unimpaired by a screen, or a screened opening with the ventilation areaaunobstr'ucted' by a window sash. No smalli advantage istheprotection of the screen from the weather under conditions where the screen is not in use. Moreover upkeep which ordinarily involves considerable labor for maintenance of the putty or other glazing material in the less expensive windows is very greatly reduced.' The window is especially advantageous for structures in which the window opening is wide relative to the height of the opening.
