METAL WINDOW FRAME AND SASHES.
Application filed May 12, 1922, Serial No. 560,288. Renewed September 2, 1925.
To all whom it may (072/07)? Be it known that I, HARRY E. CAMPBELL, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Metal Winiow Frames and Sashes, of which the following is a specification.
The invention relates more particularly to metal window-frames and sashes sliding therein, and consists in the mechanism, hereinafter set forth, whereby certain joints between the sashes and the frame are closed, the sashes are prevented from rattling in the frame, and also may be clamped in closed position so that they cannot be opened until the clamping pressure is released. The device is here shown applied to windows of the type set forth in I. S. Letters Patent Nos. 1,222,357 and 1,222,358 granted to me April 10, 1917, in which the vertically sliding upper and lower sashes are provided with laterally extending metal plates which cuter and travel in gaps formed in the inner walls of the jambs.
In my pending application Serial No. 547,- 429, filed March 28, 1922, for a metal window-frame and sashes, I have described and claimed the specific construction of frame and sashes to which my present invention is here shown applied, to which application reference is made for a more detailed description of said construction.
The accompanying drawings are horizontal sections through one jaml) and portions of the sashes cooperating therewith, said sections being similar to those shown n Figs. 5 and 6 of in application Serial No. 547,429 aforesaid. n Fig. 1 the joint at Q, between the lower sash and the inner wall of thejamb is shown open, and in Fig. 2 said joint is shown closed.
Similar letters and numbers of reference indicate like parts.
The jambs of the window-frame, one of which is shown at A, are divided internally into two compartments into one of which Bthe sash extension plates, hereinafter described, enter, while the other-C-receives the counterweights (not shown) for the sashes. The inner wall of jamb A is made in three sections 10, 11, 12 separated by vertical gaps H I which extend from top to bottom of said well. The meeting edges of section 10 and of the rear jamb wall F are hooked together. The middle section 11 of the inner wall is supported on a barrier member J by means of screw bolts, one of which is shown at 24, which bolts pass through elongated slots in said section. On the member J are flanges 25 and 26 which bear against a Wall 19 within the jamb. Flange 25 is bent over, as shown at 27.
K is the upper and L the lower sash. On the side rail of sash K in an extension plate M, and on the side rail of sash L is a similar extension plate N. These plates travel respectively in the gaps H and I as the sashes are raised or lowered.
In order to stop drafts of air from entering the room or building in which the window is installed at the joints 0, P between the middle section 11 of the inner jamb wall and the extensionplates, I have described means whereby both plates M, N are simultaneously forced into contact with the edges of the middle section 11 by the closing movement of the lower sash upon its seat. Said means comprises an incllned projection 34 on flange 26 cooperating with an inclined projection 35 on plate N of the lower sash, so that as said sash is brought to its seat the pro ection 35 rides over projection 34, so moving the sash plate N until it tightly closes the joint P. At the'same time, the pro ection 34 is moved by the same means to cause the barrier member J to slide on wall 19, this movement being permitted b the slot and bolt connections of said mem er J with section 11, as shown at 24. By reason of this movement, the turned over end 27 of flange 25 acting upon extension plate M of the upper sash forces said extension late M into contact with section 11, and so 0 oses the joint at 0. Both joints and P are thus closed simultaneously with and by reason of the closing movement of the lower sash to its seat, the position of the parts being then as shown in Fig. 1.
All of the foregoing construction is disclosed and claimed in my aforesaid applicasashes are now brou ht closedly against the edges of the middle section, it becomes possible for these parts to move unitedly in l'lld out and so be liable to rattle in the frame when acted on by a strong wind. I prevent this by the following construction.
On flange 26 of barrier member is a bracket R which carries an internally threaded sleeve S, through which passes the threaded shaft T. Said shaft extends rearwardly, preferably through the hooked joint between the inner wall section 10 and the rear wall F. On the shaft T outside of wall F is a loose collar U which bears on said wall and may be held in place by a milled head V, by which the shaft T may tated by the operator. By suitably rotating shaft T the barrier member J may be moved in the direction of the arrow a, Fig. 2, and with it, as before stated, unitedly, the middle section 11 and the extension plate M, so as to cause the extension plate N of the lower sash to close the joint with inner jamb wall section 10 at Q. The closure of this joint may be only sufficient to prevent the rattling of the sashes, or the shaft T may be rotated with sufficient force to cause astrong clamp,- ing of the plate N between wall sections 10 and 11, so that the sashes cannot be opened until the )ressui-e is released. As the shaft T cannot e turned from the exterior of the building, it will be evident that my device provides not merely a means of stopping rattling of the sashes, but an effective frictional lock which renders unnecessary any other means for preventing said sashes be ing opened for unauthorized entry from the outside.
1. A metal window frame'and sash construction, comprising jambs each having an inner wall made in three sections with vertical gaps between said sections, upper and lowersashes, plates laterally extending from be ro-.
the side rails of said sashes and entering said gaps, mountings for the middle sections adapted to permit said middle sections to move in relation to the other two sections, means within the jamb for moving both of said sashes and said middle sections in relation to the other two sections and mechanism extending out of the jamb for manual'ly operating said means.
A metal window frame and sash construction comprising jambs having slots in their inner walls and enlarged openings l ehind such slots, sashes having plates adapted to enter said slots and adjustable means within said jambs for changing the clearance between said plates and the portion of the jamb wall that lies between said slots without changing the position of any other portion of the jamb wall.
3. A window franv. and sash construction comprising jambs, each having two vertical openings in its inner wall, dividing such inner wall into two side sections and a middle section, and sashes adapted to slide in said openings and adjustable means within the jamlzs tor holding the sashes in rel t'ivcly close contact with the middle section of each jainb wall. such means being operable withoutmoving either of the side sections of the jamb wall.
4. A metal window-frame and sashes, comprising jambs, each having an inner wall made in three sections with vertical gaps between said sections, upper and lower sashes, plate laterally extending from side rails of said sashes and entering said gaps, movable supports for said middle sections within said jambs, threaded sleeves on said supports, and rotatable shafts engaging said sleeves and extending through the rear walls of said jambs.
In testimony whereof I have atlixcd my signature.
