WINDOW CONSTRUCTION.

Application filed September 14, 1923.

To all whom it may concern Be it known that we, WILLIAM J. HEATH and HAROLD D. HEATH, subjects of the King of Great Britain, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Window Construction, of which the following is a specification.

his invention relates to certain new and useful improvements in window construction of that type embodying vertically slidable supplemental stiles which carry vertically swinging sashes.

The primary object of the invention is to generally simplify and improve window construction of the above kind whereby they may meet with the requirements for a successful use.

Another object of the invention is to projacent edges of the supplemental stiles and sashes in frictional engagement for effectively excluding air from the dwellings and preventing swinging of the sashes too freely.

A further object of the invention is to provide simple and eflicient means for looking the sashes in closed relation to the supplemental stiles, and means for locking the sashes in closed relation to the frame and for simultaneously excluding air which might otherwise enter the dwelling through cut-out portions in the upper rail of the lower sash and in the lower rail of the upper sash which are provided to give clearance for the means for locking the upper sash in closed relations to its supplemental stiles.

Other objects will appear as the nature of the invention is better understood, and the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accom panying drawings and claimed.

. In the drawings, wherein like reference characters indicate corresponding parts throughout the several views,

1 window,

Figure 8 is a perspective view drawn on a larger scale, of one of the sliding bolts for holding the sashes in closed relation to the supplemental stiles, and

Figure 9 is a perspective view illustrating the manner in which the sashes may be arranged, when revolved upon axis for facilitating washing both surfaces of the sash panes.

Referringmore in detail to the. drawings, 5 indicates a window frame of any well known or preferred construction having a pair of vertical guide ways 6 formed on each usual window jamb' by a parting strip and stop strips cooperating therewith in spaced relation in which are longitudinally slidahle supplemental stiles 7, a pair of supplemental stiles being provided for each pair of guide ways, and sash 8 being placed between each pair of supplemental stiles as shown clearly in Figure 1.

As shown in Figures 1 and 5, each sash is pivoted to its stiles by means of screws 9 which extend through longitudinally arranged leaf springs 10 disposed in the outer surfaces of stiles, which screws pass through the stiles and into the adjacent sash stiles of the sash frame. The screws 9 are unthreaded except at the inner ends of the same which screw into sash stiles of the sash frame, and these screws pass through the outwardly bowed central portions of the springs lOso that when the heads of the screws are disposed against the outer sides of said springs, the supplemental stiles are held in close contact with the sides of the sashes so as to effectively exclude the en trance of air into the dwelling when the sashes are in closed relation to said supplemental stiles. ,It is apparent that the screws are provided at about midway between the upper and lower endsof the sashes so as tov form horizontal pivots. about which the, sashes may be vertically swung or tilted,

and, for practical purposes, the springs 10 are preferably disposed within grooves 11 provided in the outer surfaces of the supple mental stiles.

The upper ends of the sashes are held against swinging outwardly by means of laterally projecting pins 12 provided in the sash stiles adjacent their upper ends and projecting into notches 13 formed in the inner surfaces of the supplementalstiles. Obviously, the supplemental stiles are preferably connected to sash cords which may be attached, in the usual manner, to sash balance weights movable vertically in the sides of the window ja-mb in a well known manner, not shown.

For the purpose of effectively holding the sashes in closed stiles, sliding bolts of the form shown in Figure 8 are attached to the lower portions of the sash stiles of the sash frames, and these bolts are preferably formed from short strips of sheetmetal bifurcated at their outer ends to provide arms 1 1 adapted to overlie the inner surfaces of the supplemental stiles when in looking position, and having laterally offset tongues 15 between the arms 14 adapted to enter grooves 16 in the inner sides of the supplemental stiles. Each bolt is formed with a longitudinal elongated slot 17 adapted for reception of a screw 18 that is threaded into the sash frame for slidably connecting the bolt to the respective sash frame for horizontal movements, and the inner ends of the bolts are out turned as at 19 to provide finger pieces by means of which the operation of the bolts is facilitated.

As shown in Figure 2, the upper frame bar of the lower sash has a weather strip 20 attached to the outer side thereof, while the lower frame bar of the upper sash has a similar weather strip 21 attached to the inner side thereof adapted to contact with the lower edge of the strip 20 when the sashes are in closed position so as to effectively exclude entrance of air or the like into the dwelling, these weather strips being provided between the usual parting strips 22 of the window jamb. In order that the upper sash may be lowered, clearance is formed for the bolts carried by the upper sash by providing cutouts in the ends of the strip 20 as indicated at 23 in Figure 3. It is thus necessary to make provision for preventing entrance of air into the dwelling through the cutout portions 28 of the strip 20, and this is accomplished by means of a pair of novel locking bolts of the form shown in Figure 7 which are also utilized to latch the two sashes in closed position relative to the frame. These bolts consist of elongated strips of sheet metal having longitudinal elongated slots 24 through which are passed screws 25 by means of which the bolts are slidably fastened upon the upper surface of the upper rail of the relation to the supplemental lower sash, the outer ends of the bolts being adapted to enter notches 26 provided in the parting strips 22, and being of a form, so that when they are so positioned, they effectively cover the spaces ornotches 23 in the strip 20, thereby excluding the entrance of air through these cut-outs or notches 23 when the sashes are locked by engagement of the bolts in the notches 26. For limiting movement of the bolts to proper locking position, the outer ends of the same are provided with extensions or tongues 27 adapted to impinge against the inner surfaces of thesides of the window frames, and for facilitating operation of the bolts, the inner ends of the same are upturned as at 28 to form finger pieces. Although the projection of the ends of the bolts into the notches 26 will have a locking effect, it is primarily provided for more efficient exclusion of air at the cut-outs 23, and the locking action is primarily obtained by means of upwardly ofiset tongues 29 stamped on the bodies of the bolts and adapted to enter suitable keepers 30 when moved to locking position, which keepers are suitably fastened to the lower rail of the upper sash and project upwardly through the notches 23 when the windows are closed.

From the foregoing description it will be seen that by simply sliding the bolts upon the upper rail of the lower sash inwardly toward each other, the tongues 29 will be disengaged from the keepers 30 and the bolts will be simultaneously moved to a position to uncover the cut-outs 23 and to withdraw from the notches 26. When so disposed, the sashes are free to move vertically for being opened. As shown in Figure 9, the sashes may be swung upon the screws 9 as horizontal pivots relative to the stile bars so that the inner surfaces and outer surfaces of both of the sashes may be conveniently positioned for permitting washing of the same from the interior of the dwelling, upon release of the locking bolts carried by the sash frames adjacent their lower end portions. The construction of the several bolts employed effec- V tively holds the movable members in position and against vibration in either direction so that the supplemental stiles and sash frames will operate as units, substantially as efficiently as though the supplemental stiles and sash stiles of the sashes were integral. 7

It will thus be seen that we have provided a window construction by means of which the outer and inner surfaces of the sash panes can be cleaned without any risk of accident to the person cleaning them; that the ashes can be far more easily and better cleaned without any risk of life than with the usual non-pivoted sliding sashes;

that on account of the specific construction standing upon a chair or the like,

lower sash being cut surfaces of the window panes will be accessible from the interior of the dwelling without the necessity of the windowcleaner sitting upon the outer sill and holding on to the window for support, or like operations.

From the foregoing description, it is believed that the construction and operation as well as the advantages of the present invention will be readily understood and appreciated by those skilled in the art.

Minor changes may be made without depart-ing from the spirit and scope of the invention as claimed.

What we claim as new is 1. In a window construction, the combination with a frame having vertical guide ways, of a pair of supplemental stiles lon gitudinally each slidable in one of said guide ways a sash positioned between the supplemental stiles of each pair, said supplemental stiles having longitudinal recesses in the outer sides thereof, leaf springs having outwardly bowed central portions arranged within said recesses, and screws extending through the central portions of said springs and through the supplemental stiles and threaded into the sash stiles for pivotally mounting the sashes for swinging movement upon horizontal axes, the supplemental stiles of each pair being provided with notches in the inner faces thereof near their upper ends, and outwardly projecting pins upon the sash stiles adapted to seat within said notches for limiting the sashes to their prop-er vertical position relative to the supplemental stiles and for preventing rearward swinging movement of the upper ends of the sashes, the lower rail of the upper sash and the upper rail of the lower sash having super-imposed packing strips secured thereto, the packing strip of the away at its end to provide clearance for said bolts of the upper sash whereby the latter may be lowered, and locking bolts upon the upper surface of the top rail of the lower sash for holding both sashes closed and formed to cover the spaces formed by cutting out the ends of the packing strips carried by the lower sash.

2. In a window construction, the combination with a frame having vertical guide ways, of a pair of supplemental stiles longitudinally each slidable in one of said guide ways, a sash positioned between the supplemental stiles of each pair, said stiles having longitudinal recesses in the outer sides thereof, leaf springs having outwardly bowed central portions arranged within said recesses, and screws extending through the central portions of said springs and through the supplemental stiles and threaded into the sash stiles for pivotally mounting the sashes for swinging movement upon horizontal axes, the supplemental stiles of each pair being provided with notches in the inner faces thereof near their upper ends, and outwardly projecting pins upon the sash stiles adapted to seat within said notches for limiting the sashes to their proper vertical position relative to the supplemental stiles and for preventing rearward swinging movement of the u per ends of the sashes, the lower rail of the upper sash and the upper rail of the lower sash having superimposed packing strips secured thereto, the packing strip of the lower sash being cut away at its end to provide clearance for said bolts of the-'up per sash whereby the latter may be lowered, and locking bolts upon the upper surface of the top rail of the lower sash for holding both sashes closed and formed to cover the spaces formed by cutting out the ends of the packing strips carried by the lower sash, said last named bolts further including upwardly offset tongues intermediate the ends of the same, and keepers attached to the lower portion of the upper sash adapted to be engaged above said tongues when the sashes are closed.

In testimony whereof we aflix our signatures.
