WINPOW CONSTRUCTION.

.Application med August '7.1926. semi No. 127,797.

This invention-v relates to windows-morev to the sashes or to the frame, these being not only inefficient in a good many cases, but unsightly and in the way.

One object of my invention is to dispense with the; necessity for separatev attachments to attain the end aforementioned through novel construction of the window parts themselves. s v

Another object ofmy invention is to offset passage of draft air by trapping and deflect. ing it at the regions of juncture between the Window frame and the'sashes.

Still another object is to enable securing of the window sashes against operation with assurance of absolute weather-tightness in the event of extreme cold and high winds.

One wayin which the foregoing as wellas other objects and advantages of this invention may be readily secured in practice will be apparent from 'the detailed YYdescription hereinafter of the typical embodiment shown in the drawings.

Fig. I is a part horizontal section of my novel window structure; and

Fig. II, a fragmentary view 4illustrating certain arts differently adjusted.

The rame or jamb of thewindow, herein comprehensively designated 5, has at each side (only one being represented) a member 6 conveniently -formed from sheet met-al to -t-he hollow configuration shown to accommodate up and down movement of the

sash balance weights

7, 8. Themember 6 is usually known in the art as the weight box, and, in the present instance, will be observed as having an opening 9 at the inner side. This opening 9 is bridged by a part 10 which may be conveniently termed the sash runner strip, the same having

rearward flanges

11, 11

engaging grooves

12, 12 formed in the weight boX 6. Supported with capacity for free rotation in bearing apertures of theY sash runner strip 10 are adjusting* screws 1313 that take into the retroverted mar.- ginal edges 14, 14of the opening 8 inthe side of the weight box By this arrangement, the sides of the window frame 5 'are rendered expansible and contractable for .al

preferably identical in construction, each` comprising a main frame member 17 which 1s offset as at 18 to provide a recess for 4the edges of the window pane 19'together with the weather acking 20, and a erimetric ref taining mem er 21'to overlap t e packing on the ln-side of the sash. The member 21may be secured by any convenient removable fastemng means, such, for example, as screws whereof one is depicted at 22. As shown, the marginal portions .23, 23, afforded by the

members

17, 17 of the

respective sashes

15, 16, extend into

guide slots

24, 24 which are coextensive with integrally-formed tubular pockets or

channels

25, 25 of the sash runner strip 10. The channels 25, 25', it will be noted, are rounded in cross sectional configuration, and the sash vmargins 23 formed with

counter-rounded anges

26, 26.

By means of the screws 13e-13 aforementioned, the sash runner strips l-at opposite i sides of the jamb 5-may b relatively adjusted to establish the normal relation of the parts shown in Fig. I,-that is to say-with the

margins

23, 23 of the

sashes

15, 16 running free in the associated

guide slots

24, 24, whlle the -ends of the

ianges

26, 26 contact with the walls of the respective

tubular channels

25, 25. Under these conditions, draft air entering through the clearances at the

guide slots

24, 24 will be trapped in the

channels

25,25, and; by virtue of the rounded configuration of the latter and the counter rounding of the

sash flanges

26, 26, will be whirl' 1 and deiected for expulsion at the region of ent as graphically indicated by the arrows in ig. I, and thereby prevented from getting past the

sashes

15, 16.

If desired, the

sashes

15, 16 may be made absolutely. weather tight in extremely cold and windy weather when there is no necessity for opening them for ventilation, by

tightening up the adjusting screws 1313.l

as Y

well as with provisions whereby the sashes may be secured against operation in absolute weather-tight relation to the window -frame or jamb during periods of extreme cold and wind Vwhen universal ventilation is not essential or desirable.

while i have shown and described my invention in connection with Va fire-proof window wholly of metal, the underlying principles are obviously capable of embodiment.V in windows constructed from other materials with attendant advantages analogous t those herein pointed out.

'Having thus described .my invention, I claim:

1. In a window, the combination of sliding sashes, and a jamb aording tubular channels with longitudinal guide slots for engaging side margins of the sashes, the channels aforesaid being rounded in cross sectional configuration and the lapped sash margins counter-rounded for cooperation in lwhirling draft air thereby to check and'prevent it from getting past the sashes.

2. In a fire proof window, the combination of sliding metallic, sashes and a hollow sheet metal jamb affording tubular channels with longitudinal guide slots for engaging side anges of the sashes, the channels aforesaid being rounded in cross section and the sash flanges counter-rounded for cooperation in whirling draft thereby to check and prevent it from getting past the sashes. 3. In a window, the combination of sashes,

and a jamb with longitudinal guide slotsI for engaging margins of the sashes with a i clearance fit and coextensive tubular channels of rounded cross section to take counterrounded flanges of the sashes, the sides of the J amb being contractable thereby to effect binding engagement of the flanges aforesaid with the channel walls and concurrent displacement of the plane of the sashes to close the guide slots for absolute' Weather-tightness.

4. In fireproof window construction, the combination of metallic sashes, a jamb comprising sheet metal weight boxes open at their inner sides, and sash runner strips, also of sheet metal interitting the jamb openin s, said runner strips embodyin integral tu ular channels to take lateral anges along the sliding edges of the sashes, and

vmeans enabling adjustment of the runner strips toward the jamb sides for binding contact with the flanges aforesaid and Weather-tightness.

5. In ireproof window construction, the combination of sliding metallic window sashes, a jamb comprising sheet metal weight boxes open at their inner sides, and sash runner strips also of sheet metal interitting the jamb openings, said runner strips einbodying longitudinal guide slots and coextensivetubular channels of rounded cross section to take counter-rounded flanges of the sashes, and means enabling adjustment of the runner strips toward the jamb sides thereby to effect binding engagement ofthe flanges aforesaid with the channely Walls, and concurrent displacement of the plane of the sashes for closure of the guide and slots and absolute weather-tightness.

In testimony v whereof, I have hereunto signed my name at Philadelphia, Pennsylvania, this 4th day of August, 1926.

FRANK C. FERGUSON.
