1 Claim. 1

Thisinvention relates to window sashes, is particularly concerned with window sash construction, ismore particularly concerned with a device whereby the sashes may readily beraised and lowered and wl'xereby the sashes may be ad justed at substantially any desired position, and is still more particularly concerned with weather stripping to prevent cold air from entering into .the building, and is most particularly concerned with runways disposed between the siderails of the sash and the side members of the frame and adapted for the smooth movement of the said sashes.

There are presently many window sash constructions to be had, and there are many devices Vadapted for raising and lowering of window sashes. Howeven the devices presently had for raising and lowering, and adjusting sashes in position, rely principally on devices having sash weights. Sash Weights are not only unwieldy of installation but are extremely awkward of repair. Such devices are for other reasons quite undesirable! It is therefore an object of the, present invention to `provide a sash construction. It is a further' object to provide'a window sash construction whereby the sash may readily be raised and loW`- ered. It is a further object to provide a window sash construction whereby the sash may readily b adjusted in any desired position. a further object to provide a window sash weather stripping. further object of this invention is the provision of a window sash construction having ease of construction and having economy of fabrication.

Y I have now discovered and invented in a window sash construction, a frame, an upper sash, a lower sash, two pairs of sash runways, each of the said sashes having a runway disposed on either side thereof, each of the said runways being interposed between the Side rails of each of the sashesand the said frame, the runways of each Side of the said frames being disposed back to back in respect to each other, a recess in each side rail of each of the sashes being adapted for conforming of the said runways with the side rails of the said sashes, four coil springs, each of the said runways an open space, each of the said spaces having longitudinally disposed therein the said space one of the said springs, each of the said springs being secured at their upper ends of the said frame, the lower ends of each of the said springs being secured to the lower bottom rails of each of the two sashes, and the said springs being arranged to hold the said It is still sashes in their adjusted position, and I amnow able to avoid the disadvantages of the prior art andam ableto `accomplish the objects set forth.

Referring tothe drawings: I

Fig. 1 isan elevation View of la frame from the room side.

Fig. 2 is avertical section taken along the lines 2-2 of Fig. l.

Fig. 3` is a cross section view of the runways device into` which the sash conforms.

Fig. ris a horizontal section taken along Vthe lines 4-'4 of the Fig. l. i i

Fig. 5 is a vertical section taken along the lines V5--5 0f the Fig. 1.

` In 'the Fig. l the lower window pane I is setinto `the side rails 2, the bottom rail 3, and the inside meeting: rail 4. The upper window pane I is set into the side rails 2a, thetop rail of the upper frame, and` the lower inside meeting rail 5 of the upper frame. The numeral I3 designates the vertical stops from the interior of the room, and the numeral I4 designatesthe vertical stops from Athe weatherfside. `The numeral' designates the runway device for the lower sash. y

The Figi 2 isa verticalsecti'on taken along the line 22 of` Figfl, and shows the longitudinal right side'view of the runwayl device 8a for the upper sash. `The numeral @designates the coil spring `for the lower sash. The numeral I0 desig- -natesfthe coil spring for the upper sash. The clip Ia is formed from-the spring 9, andthe said clip I'Ilctv is held over the `upper end of the run- `away 8. The cliplb is formed from the spring IIJ, and the said clip IIlb is held over the upper end of the runwayv 8a.

In the Fig. 5 is shown'the weather stripping 6 `set into` the rail 5, at` the meeting of ythe'said rail 5 and the rail 4. One edge of the said weather stripping"J 5i iss'et .into alongitudinal groove formed in the frame 5, and the said stripping is frictionally held thereto by the said frame.

In the Fig. 4 a cross section of the two runways are shown in small scale, while in the Fig. 3 is shown a cross section of the runway in larger scale. In the Fig. 4 the recess 1, cut into the side rails 2 and the side rails 2a is shown.

The lower end of the spring 9 is secured to the thin steel bar I I. The lower end of the spring I 0 is secured tothe thin steel ybar I2. The steel bars I I and I2 are nailed to the lower ends of the

side rail

2, and 2a respectively.

Referring now to the Fig. 3 in which the larger cross sectional view of the runway is shown, the numeral I5 designates the outer side wall of the runway, the numeral I6 designates the inner window and side wall of the runway, and I1 the arch of the runway, which arch rests against the middle of the side rails. The side rails of the sash are movable between the members I5 and I6. The numerals I8, I9, and designate the flat surfaces, and are merely a continuation of the member I6. The numeral 2l designates an angle continuation from the surface 20, and the edge bent upon itself. The numeral 22 designates the space in the runway for holding the spring 9, and the spring I0. The numeral 23 designates the opening between the member I6 and the angle 2I throughl which the bar II, or bar I2, projects to engage the lower end of the spring 9 or the spring IIJ. The numeral 24 designates the edges of the arch I1.

4The window frame comprisesv the window sill 25, the under surface 26, and the two side frames. The lower sash is bordered at the bottom by the sill 25, and is bordered at each of its sides by each of a pair of runways 8 and 8a, disposed as shown in Fig..4. The springs 9 of the lower sash are disposed Within the space 22-of the runway,

and are secured at the top end by the clips IIIa, which clips are part of the springs, to the upper end of the runways. The lower end of the said springs 9 of the lower sash is secured to the bar I I.

I wish to point out that the structure of the. runway is specifically fabricated and when seen from the cross section View as in the Fig. 3, the outer side wall is folded somewhat upon itself, the arch I1 is substantially 80 degrees in respect to the said outer wall, the flat surface I8 is substantially 90 degrees from the flat surface I9, the at surface I9 is substantially 90 degrees in respect to the at surface 20, and the angle continuation from the surface 20, which is the second outer wall is substantially 90 degrees from the surface 20.

I wishparticularly to point out that in the window sash construction of my invention there is great ease and economy of fabrication. The

runways may be constructed of light gauge sheet metal andthe machinery therefore is very inexpensive -of construction. The assembly of the runways with Ythe rest of the window construction can be accomplished without the need of any special machinery, and without the need of any special skill;V an ordinary carpenter can make `the complete assembly with ease.

making any necessary repair or replacement. I want further to point out that great versatility of the construction is possible. The entire construction comprising the frames, sashes, and all other members may be fabricated, assembled, or not assembled, in the plant, as it is most convenient to the builder or the fabricator.

The window construction of my invention may be used on any knocked-down window frame; and the frames can be'made sat the point of the cheapest manufacture. The rabbeting on the side rails may be done at the point of sale after the sashes have been assembled. There is no need for varying transverse sizes of runways since the runway of a given transverse size is adaptable for any window construction, and all that is necessary is to vary the length of the runways. To adjust for the varying weights of window sashes, it is only necessary that the diameter of the spring wire vary from substantially 0.141 inches for the smallest and lightest sash, to 0.064 inches for the largest and heaviest sash. The length of the spring Varies according to the height of the component sashes.

I claim:

In a window sash construction, a sheet metal runway comprising a narrow outer wall, the said outer wall being substantially folded upon itself, an arched surface, the said arched surface extending therefrom the said outer wall and the said arched surface being substantially eighty degrees in respect t o the said outer wall, an inner wall, the said inner wall extending from the arched surface and formed by folding of the sheet metal upon itself, a flat surface, the said flat surface extending from the said inner wall, a second flat surface, the second flat surface extending from the first at surface in a direction substantially ninety degrees from the first flat surf-ace, a third flat surface, the third fiat surface extending in a direction substantially ninety degrees from the second flat surface, a second outer wall, the said second outer wall being folded upon itself and extending from the third ilat surface in a direction substantially ninety degrees from the said third at surface.
