'EDMUND H. LUNKEN, OF CINCINNATI, OHIO.`

WINDOW.

Specification of Letters Patent.` Patented Dec. 30, 1919.

Application filed August 13, 1918. Serial No. 249,728.

To all 'whom 'it may concern.'

Be it known that I, EDMUND H. LUNKEN,

vided in the upper portion ofthe sash.

frame for the reception of the sash to give a free and unobstructed window opening, provision also being made for window screens located outside the sash and also adapted to be pushed up into the window pocket either to obtain access to` the sash, or for winter storage of the screens when their use is not required.

` It is the object of my present invention toprovide in connection with such windows for a storm window construction.- j i Heretofore wherever storm windows have been desired during the winter months, it has been necessary to fit into the window opening an extra sash which has'to besecured in place temporarily for the winter season, a matter of considerable' expense, both for installation and removal. It is the object of my present invention to provide a storm window construction in which the storm .window sash can be permanently mounted in the window casing and pushed up out of the way when not in use.

I alsoprovide in this connection a certain 4 novel construction for applying and mounting the weather stri for the cross rails. of th'e sash, which obviates the special fitting of the weather strip andwithwhich accuracy in mounting the strip so as to obtain a perfect closure is readily attained. y

I also in connection' with the sash provide for a spring check on the sash to prevent the throwing up of the sash too rapidly against the head piece of the casing.

These various features and otherpoints of novelty will be hereinafter particularly pointed out and claimed.

`foi-the window screens.

In the drawing, 1 n Figure 1 is a vertical'longitudinal section of my improved window construction.

Fig. 2 is a transverse section of a portion' of one of the side stiles, taken on the line A, A, of Fig. 1. i

Fig. 3 is a detail longitudinal section, taken on. the line B, B, of Fig. 2.

The pocket window is provided with the usual lower andupper sliding sashes l, 2, with the .

meeting rails

3, 4, the sashes being mounted in side stiles 5, 6, provided with the inside and outside beads 7, 8, with the parting bead 9 for the two sashes, sill 10 and head piece 11'.. The sash stiles run to the top of the pocket above theiwindow opening and the head piece closes the pocket top, while the front of the pocket is in the construction illustrated formed of corrugated sheet metal 12 suitable for plastering. The outer wall of the pocket is inclosed by sheeting 13,y over which the weatherboarding` 14 or other outside finish is secured.

he window casing is also provided with the finish 15 and the sill piece 16. l The sashes are provided with the usual

sash cords

17,18, which run over sash pulleys 19 at the head of the stiles and to the sash n cords are attached the usual weights in the weight box behind the stiles. f Outside of the sash' stile'sis the vsheet 'metal channel strip 20, one on each side, to serve as a guide y Thesescreens are preferably metal frames, 2l' for the lower sash and lower frame, and 22' for the upper, with wire screening 23, 24, for the respective screens. As illustrated, a flanged strip is provided for the top rail'of the lower screen to confine itbetween the upper the upper rail of the upper screen is formed of double thickness to lill out the opening head piece to the sill which is provided in the Sli casing with the parting bead 28 and formed at the outside by the inner bead 7, hitherto referred to. Mounted in this additional runway is an additional sash 30, provided with the sash cord 31 and the sash pulley 32 at the head of the stile.

To form an effective closure of the window pocket and ordinary sash, great care must be taken that the weather stripping for the cross rails of the additional sash shall lit accurately. On the upper rail is secured the weather stripping support 33, provided with a strip' of felt 34 rejecting beyond the face of the support strlp 33, and when the additional sash is drawn down opposite the upper sash, this felt strip 34 has a close bearing along the bearing strip 35. In order that an accurate fit may be obtained, a shoulder 36 is provided for the lower face of the strip 33, with a corresponding shoulder on the upper surface of the upper rail, and these shoulders will insure whenproperly cut a snug bearin of the felt 34 on the bearing strip 35. Thisweather strip fills up the space between the side of the sash and the upper cross piece 37 of the inside bead which space. is left in order to prevent this bead from marring the outer surface of the sash when raising or lowering the same.

At what corresponds to-the meeting rails .3, 4, ofthe ordinary sash, that is the cross rail 38, there is also provided a felt strip 39 which bears against the inlaid bearing strip 40 carried by the upper rail 3 of the sash 17 so that when the

rails

38 and 3 are opposite each other, there shall be a tight closure between these cross rails.

lVith a pocket window construction, inasmuch as the y sashes run up for their full length into a pocket, it is found that with a well-balanced sash, in raising the sash the user is very apt to give such a momentum to the sash as to cause it to strike with a considerable blow against the head piece and the sash lights are liable to be broken by the jar, or the sashotherwise damaged. In order to check this movement and serve as a brake in raising the sashes into the window pocket, I therefore secure in the pulley stile so as to bear against the Side front. face of the sash on each side, spring metal strips 41, which bear against the side members of the sash and act as a very effective brake and check the movement. As illustrated in the drawing, "I have applied these spring strips in the path of the additional sash, but for each of the other sashes similar strips may be mounted. l

In fitting the weather strips for the cross i tion as well as the entrance o withthe bearing strip with which it is to make contact.

It is thought that from the foregoing description, the use and advantages of my 1nvention will be obvious.

It is intended to construct and ship the entire casing with all its parts properly fitted as a single package.

Except during the winter months the additional sash will be pushed u. into the pocket and will be entirely out of) theway. The lower sash is strippin 42 to furnish an accurate fit at the base an this 4lower sash can be raised or lowered, and the two ordinary sashes used as usual by merely raising the storm sash temporarily. `With the vaccurate fitting of the weather strip material and the complete el0- sure of the pocket opening by the additional sash, I have found that it is not necessary to provide any lower storm sash, and that the single sash shown' serves sufficiently to meet all the exigencies of the weather. The air space between the upper sash and the additional sash very effectively revents radiaair around the joints.

Having thus described my invention, what I claim as newand desire to secure by Letters Patent, is y 1. In a pocket window construction, a window frame with u per and lower sashes mounted to slide therem, and into the pocket, with the upper sash locatedV and adapted to close the space between the lower sash and the outer 'wall of the pocket at the mouth provided with weather thereof, and an additional sash mounted to slide in the frame and into the pocket, and

positioned and adapted to close the space.`

between the lower sash and the inside wall of the pocket at the mouth thereof.
