WINDOW CONSTRUCTION Application flleiAukixstlB, 1927. serial no. 213,729.

This invention relates to window construction and has for its object to provide a window in which the sashes can be securely clamped in place in closed position or any position of adjustment, but may be loosened so as to be freely movable when it is desired to open or close the window.

A further object of the invention'is to provide a window of this class wherein the mech anism for holding the window in fixed'position extends throughout the entire length of the window and not only makes a tight connection with the window throughout the length of the window, but also tightly engages the window frame and thereby makes the window weatherand wind-proof to an extent impossible with windows operating in fixed guideways and which must therefore be more or less freely movable.

A further object of the invention is to provide a window of this character which costs but little more than an ordinary sliding sash window construction, which may be readilynstalled inhouses already built, as well as in new buildings, and'which is adaptable to either wooden or metal window frames- A further object of tlfe invention is to provide a window construction of this character which has no unsightly parts and which in effect is indistinguishable from ordinary sliding sashwindows except for the'provision of a small operating member which may be a small handle, a thumb screw or similar inconspicuous part. I It may be a window of more than two sashes and may be used for the operation of shutters or screens. It may\be I used for windows in railway or other cars as well as in any type of building. It may be used for windows of one movable pane of glass as in an automobile.

In the accompanying drawings I have disclosed my invention applied to a wooden frame sliding sash window of usual construction.

In said drawings,

Fig. 1 is a vertical sectional view through one side of a window frame equipped with my improvement and showing the adjacent portions of the sashes in-elevation;

Fig. 2 is vertical section at right angles to Fig. 1, on the line 2-2 thereof;

Fig. 3, is a pers ective view artly in section on an enlarge scale of the ower portion of the window;

Fig. 4 is a sectional view on line 4-4 of Fig. 1 showing the parts adjusted to loosen thedwindow so that 1t may be raised or lowere F-i 5 is a similar view with the parts adjuste to the ositionfor clamping the window tight; and

Fig. 6 is a sectionalview on an enlarged scale'on line 66 of Fig. 1.

Referring to the drawings, 1 is the vertical member of the house wall at one side of the window opening, ,and 2 and 3 indicate, re-;

spectively, the upper and lower sashes formmg the window. The sashes 2'and 3 are of a width somewhat less than the space between with strips 7 and 8,

the member 1 and the corresponding member the principal parts of my invention and consists preferably of sheet metal, such as pressed steel, in the form' of a double channel. The sash guide 9 is of a length to extend from the bottom member 10 of the window frame to the top member 11, and the twd flanges at the edges of the sash guide extend, respectively, between the spaces between the-sash frames and the adjacent strips 7 and 8. The inner faces of these flanges, that is, the faces adjacent the sashes, are inclined or beveled as shown, and the adjacent ortions of the sashes are correspondingly eveled so that as the sash guide is forced outwardly or toward the sashes the two sashes will be clamped together. The middle strip 12 maybetapered also, butis preferably flat, so that formed not only between the sas the sash frames will be drawn toward each other by the-clamping'action of the sash Any suitable mechanism may be em loyed for shifting the sash guides toward an y from the sash frames to lock the sashes in position in the manner described. The mechanism shown in the drawing consists of a rectangular sheet metal frame 13 of a length slightly less than the height of the window and with its two vertical members in engagement with the rear face of the sash guide 9 at its edges: The frame 13 is vertically movable and has attached to it a series of rods or bars 14 whose ends are cylindrical, as shown, and project beyond the edges of the frame 13 and the sash uide 9, in position to engage the inclined'facesof cam blocks 15 attached to the inner faces of the frame members .5 and 6 adjacent the ends of the bars 14.

Three bars 14 are shown but the number may obviously be greater or less if desired, depending primaril upon the height of the window. The bloc s 15 are thicker at the bottom than at the top so that when the frame 13 is lowered it will thrust the sash guide toward the sash frames, and when elevated will permit the sash frames to be withdrawn and thereby free the sashes.

To insure the positive release of the sashes when the frame 13 is raised there is provided, as shown in Figs. 3 and 6, a spring device comprising a bar 16 attached to the back of the sash guide 9 at its middle part and with its ends bent outwardly to clear the frame 13 and extend beyond the frame to thereby provide a space between the ends of the bar and the strips 7 and 8. Each end of the bar carries a cup or spring guide 17 in which is seated a spring 18 working between the bottom of the cup and a plunger 19 whose head presses against the inner face of the strip, whereby the spring will be compressed by the movement of the sash guide toward thesash frames and when released will force the frame outwardly to positively free the sash frames. The extent of movement of the springs is limited by pins 20 inv the end of the plungers. Spring; bars 16 are provided at both the top and bottom of the window, as shown in Fig. 2, and obviously, of course,

other bars may be provided at intermediate points, particularly with high windows.

Any suitable mechanism may be employed for raising and lowering the frame 13. As

a convenient device for this purpose I have illustrated a lever 21 fulcrumed at'its far end to the inner face of the outer sash frame-- Figs. 2 and 3. This pivot opening is sufiiciently large to give the necessar play in raising or lowering the lever. The ever is' pivoted to the bottom cross. member of frame 13, and its outer end terminates in a handle 22 whereby it may be readily operated. A block 23 is attached to the lever back of the handle and this block works in a vertical guideway 24 attached to the face of the window frame, the frame 13 being provided with a lock 25 whereby the block 23 is locked in either upper or lower position, as desired.

Instead of block 23 attached to the lever back of the handle there may be a metal guard, closing the opening in which the lever operates and extending under a guideway so as at all times to be under a thumbscrew which may be screwed down so as to hold the lever firmly at any point.

It is of course to be understood that my invention is not limited to the particular devices for operating the frame 13 or the wedge and rod construction. for forcing the sash guide towardand from the window sashes. While the mechanism illustrated constitutes the preferred form in which the invention is to be embodied, other mechanical movements may be employed instead, for example, eccentrics pivoted on the window frame pressing against the back of the sash guide might be employed.

As stated above, the sash guide extends from top to bottom of the window and is slotted at the top to receive the edges of the pulleys for the window weights. The flanges at the edges of the sash guide are, however, continuous from end to end, and consequently when the window is closed and the sash guides clamped against the sash rails a weather-tight joint will be formed throughout the length of the upper sa'sh between the sash and the sash guide and also between the sash uide and the window frame. There will also be a weather-tight pressure between the sashes where they overlap and between the inner face of the lower sash and the adwill give way before the window willmove,

and unless the handle of the lever 21 be posi-' tively pressed downward the windowsvill remain locked, for the inclined faces of the blocks 15 are very gradual and under the pressure brought about by the clamping action. the frame 13 will be held in place until positively elevated.

1 inseam:

It will be understood, of course that it is not necessar to have sash guides at both sides of the win ows for adjustment in the manner described; The sash guide at one side may be movable and at the other side may be of the samedesign but fixed in osition whreby the movement of the mova 1e sash guide will force the sash against the-fixed sash guide and thereby clamp the sashes at both edges. When so constructed, spring buttons may be inserted in the fixed sash guide to release the window when pressure on the opposite side of the sash is released. When two movable sash guides are employed they may be coupled to receive the top of the upper sash and bottom of the lower sash when the window is closed, to thereby clamp-the window around its entire edge and make it substantially airtight. Such additional channels are, however, not necessary, as ordinary tongue-andgroove metal weather stripping makes a'sufficiently tight joint at the top and bottom of the window for all practical purposes. Such Weather stri pin-g is not, however, satisfactory at the side edges of the window"for the reason that if the en agement is tight enough to keep out the weather it makes the window too tight to open and close freely.
