the sash-carrying frame from the stationary frame. 7

A further object is to provide such a window structure of simple and inexpensive construction, which may be assembled as a unit and mounted in the usual wall opening as an ordinary window frame, thereby provldmg such a structure well adapted for use in the building art. 7

Other objects of the invention will appear from the following description and the accompanying drawings, and will be pointed out in the annexed claims. y

In the drawings there, has been disclosed a structure designed to carry out the various objects of the invention, but it is to be understood that the invention is not confined to the exact features shown, as various changes may be made within the scope of the claims which follow.

The novel Window structure featured this invention includes a stationary frame comprising the side jambs 12, sill 13, and the upper cross member 14:, suitably secured to the jambs 12, to provide a rectangular frame adapted to be mounted in the usual wall opening 20, as shown in Figure 7. Gasings 15 are secured to the outer edges of the side jambs 12, and are adapted to overhang the inner faces thereof, as particularly shown in Figure 7, to provide a seat 16 adapted to demountably receive a storm sash or screen 17, mounted therein from the interior of the building, as shown in dotted lines in Figure 6. A casing board 18 is secured to the upper cross member 14 of the stationary frame, and likewise overhangs the lower face thereof to provide a seat at the upper portion of the frame adapted to receive the storm sash, as shown in the various figures of the drawings.

A feature of this invention resides in the means provided for supporting the usual sash in the stationary frame. Such means consists of a sash-carrying frame demountably supported within the stationary frame. This sash-carrying frame comprises grooved side jambs 19, having their upper ends secured together by means of a similarly grooved head jamb 21. The usual upper and

lower sash

22 and 23 are slidably mounted in the grooved or rabbeted jambs 19, as particularly shown in Figures 1, 3 and 7. The lower ends of the grooved side jambs 19 are preferably inclined and adapted to be seated upon correspondingly inclined blocks 2%, forming in effect, continuations of the jambs 19, when mounted in the stationary frame. The blocks 24- may be suitably secured to the main jambs 12 of the stationary frame or to the sill 13.

The lower, inner portions 25 of the grooved jambs 19 are pivotally connected to the jambs b 1 means of hin 'es 26 shown )artieularl in .l b v Figures 3, 4 and 5. These lower hinged sections'25 are provided with grooves 27, adapted to be aligned with the grooves 28 in the jambs 19, when the hinged sections 25 are in normal position, as shown in Figures 1 and 1. By thus pivotally connecting the sec ions 25 to the jambs 19, the sash 23 may readily and quickly be removed from the sash frame by swinging the sections 25 inwardly to the positions shown in full and dotted lines in Figure 3, after which the sash may be removed f-rom the sash-carrying frame. suitable fastening means, such as screws 29 and 31, are provided to secure the sash-carrying frame, including the hinged sections 25, to the stationary frame. (See Figures 1 and Means are provided at the upper portion of the sash-carrying frame for counter-balancing the weight of the sash. Such means preferably consist of suitable flanged

drums

32 and 33, rotatively mounted upon the head dew frames.

jamb 21, and having

flexible connections

34 and 35 connecting them, respectively, with the outer sash 22 and inner sash 23, by such means as hooks Each pair of drums and 33 are connected together by means of cross members 37, each having a torsion spring 38 mounted therein, as shown in Figure 9. Each torsion spring 38 has one end secured to a member 37 and its other end scoured to one of the brackets 39 supporting the drums 32 and These springs are constantly under tension and tend to rotate the

drums

32 and 33 in a direction to lift the

sash

22 and 23. The tension of the springs 38 is sufficient to substantially counterbalance the weight of the sash.

Means are provided for locking the

drums

32 and 33 against movement when the sash are to be removed from the sash-carrying frame for such purposes as cleaning or repairs. Such means preferably consist of threaded stems l1 and 12, rotat'ively mounted in brackets 13, secured to the upper portion of the head jamb 21. Angle brackets 14- and -15 are received in threaded engagement, re-

spectively, ith the threaded

stems

41 and 12, and are adapted to be moved into and out of engagement with the cross members 37 by rotation of the

stems

41 and 42. (See Figures 10 and 11.) The portions of the angle brackets 4 1 and 15 engaging the members 37 are preferably corrugated or rouglr cued, to provide a gripping surface adapted to arrest the movement of the members 3?, when the brackets are moved into engagement therewith, and the sash are removed from the flexible connections 34 and Each threaded stem is terminally squared to receive a suitable key member (not shown) inserted through openings 16, provided in a finishing plate 47, secured to the inner face of the inside top casing 18, as shown particularly in Figure 2. Inner side casings 49 may also be secured to the inner edges of the main jambs 12 to provide a finished appearance of the frame within the building, as is customary in window structures of ordinary construction.

The construction of this novel window structure is such that. it may be mounted in wall openings of ordinary size, such are commonly provided for ordinary win- The stat" ;nary frame. including the

outer casings

15 and 18 and also the demeuntable saslrcarrying frame comprising the grooved jambs 1) and 21, may be assembled as a unit and mounted in the wall opening as an ordinary window frame. By removing the sash-carrying frame from the stationary frame, the sash may readily be mounted therein and connected to the sashbalancing mechanism at the upper portion thereof, after which the sash-carrrying frame, with the sash mounted therein, may be mounted as a unit, in the stationary frame 29 and 31.

and secured therein by means of the screws The grooved jamb 21 of the sash-carrying frame is preferably relatively thicker than the upright jambs 19, in order to provide a shoulder 51 adapted to abut against the adjacent edge of thecross member 14 of the stationary frame, to provide a limit stop for the inwardmovement of the sash-carrying frame. By hinging the lower, inner portions of the side jambs 19 the lower, inner sash may readily be removed from the sash-carrying frame, as shown in Figure 3 and as hcreinbefore described.

The upper sash may also be removed from the sash-carrying frame by disconnecting it from the sash-balancing mechanism and lowering it to the bottom of the frame, after which, when the hinged sections 25 are swung upwardly to the position shown in the dotted line in Figure 3, the outer sash may be tilted outwardly, as indicated by dotted lines in the same figure after which it may be readily lifted clear of the sash- V carrying frame for cleansing or repairs.

The lower glazings or panes 52 of the storm sash 17 may be mounted in a frame 53 hinged to the frame of the storm sash, whereby they may be swung outwardly to an open position to admit fresh air into the building. The storm sash may readily be removed from its seat after the sash-carrying frame has been removed from the stationary frame, as clearly shown in Figure 6. 'When the storm sash is mounted in the stationary frame and the sash-carrying frame also is mounted therein, as shown in Figure 4, the latter will engage the storm sash and securely hold it in its seat, thereby preventing cold air or moisture from entering the building between the storm sash and its supporting means. 7

It will also be noted that the storm sash may be mounted in the stationary frame and removed from the interior of the building, thereby eliminating the usual disadvantages encountered when hanging or mounting storm windows and screens from theexterior of the building, as is customary with present window structures.
