Specification of Letters Patent.

Patented June 9, 1914.

Application filed March 1, 1913. Serial No. 751,411.

To all whom it may concern Be it known that 1,; ELOF R. LEONARD, a citizen of the United States, residing at Woodclifi', in the State of New Jersey, have invented certain new and useful Improve ments in Window Frames and Sashes, of which the following is a specification.

My invention relates to window frames and sashes so arranged that the sashes may not only be raised and lowered, vertically, but that they may also be tilted or inclined at an angle to the vertical, as well as readily removed from and replaced in the frame, all as hereinafter more fully described and claimed.

In the drawings Figure 1 is a vertical, sectional view of my improved window frame and sashes; Fig. 2 is a similar view of the window frame, but it shows the sashes in full lines and set at an angle to the vertical; Fig. 3 is a top view partly in section of the frame and sashes, the upper part of the frame and the left hand portion of the upper sash being shown in section; and Fig. 4 is a front view, shortened by breaking away portions, of one side of the frame, sashes and attachments.

Corresponding reference numerals designate corresponding parts in all the figures.

The frame 1 is preferably made of sheet metal, and is provided with front stops 2 and 3 for the outer and inner sashes respectively. These front stops, 2 and 3, are preferably provided with grooves 41 and 5 adapted to receive flanges 6, 7 forming weather strips on the edges of the respective sashes. In the inner side of the frame are also formed vertical grooves or recesses, in which travel the pivots 10, 10 and 11, 11 of the upper and lower sashes. These pivots also serve as anchors for the chains 12, at either side of the frame, each of which chains runs over a pulley 13, in the top of the frame, so that the sashes act as counterbalance weights, each for the other.

The upper sash is provided at or near its top on one or both sides with a sliding bolt 14, which may be projected into the groove 8, so as to retain the sash ina vertical position in the frame.

The side of the frame is provided with an upper sash stop, which is shown in the drawings as consisting of a sliding bolt which can be entirely housed within the frame or pushed out therefrom so as to intercept and support the upper sash when it is swung forward, as shown in Fig. 2. And it will be seen that, in consequence of this arrangement, the upper sash may be lowered slightly, the bolts 14: withdrawn from the grooves 8, the bolt 15 projected, and the sash swung inward upon its pivots 10, 10 into the inclined position shown in Fig. 2, where it will be supported by the stop-bolt 15; the angle at which it is inclined being governed by the point at which the stop-bolt is placed in the frame. If it is desired, the stop-bolt 15 may he slid. out of the path of the upper sash, and the sash may be lowered into a substantially horizontal position where it may be supported by the top of the lower sash, when the latter is inclined inward, as shown in Fig. 2.

To one side of the lower sash is attached a bracket 16, carrying a swiveled guide head 17, through which slides a curved rod 18, pivoted at its upper end to a sleeve 19 which slides in the frame-groove 9. The chain 12 travels freely through the sleeve 19, which, however, is prevented by the chain from leaving the groove 9. The lower end of the rod 18 is provided with a detachable screwknob 20, or other suitable means for preventing its slipping out of the guide 17; and it may be locked in any desired position in the guide 17 by means of the set screw 21 mounted therein. This arrangement permits the top of the lower sash to be swung in from the frame, to any distance permitted by the length of the rod 18, and to be locked at the desired position by means of the set screw 21. As the sash is swung in, the sleeve 19 will slide down the chain lowering its end of the rod 18, thereby increasing the distance to which it will permit the sash to be swung in. In this manner the upper part of the lower sash may be swung inward without raising it free of the sill, and with out moving the upper sash from its ordinary vertical position. And the lower sash may also be raised and lowered in the frame while in its inwardly inclined position.

By removing the screw-knob 20 from the end of the rod 18, and slipping the rod out of the guide 17, the lower sash may be lowcred into a horizontal position, and its pivots 11 removed from the grooves 9 by tilting the sash sidewiso, so that the sash may be taken entirely out of the frame for cleaning, repair or other purposes. In this case the upper sash may be allowed to slide down to the bottom of the frame. Or the bottom sash may be allowed to turn upside down, its weight being supported by the upper sash. Again, the lower sash may be raised, and held up by any suitable means, as for instance the sliding bolt 22. This will bring the top of the upper sash, when lowered,

and the top of the upper sash is provided with a tongue 27 cooperating with a groove 28 in the top of the frame so that the frame and sashes are providedwith interlocking weather stops along all their meeting lines. 7

By means of my improvements, I am enabled to produce a window frame provided with self balancingsashes either of which can be swung inward at its-top without interfering with the other; either of which may be readily removed from the frame without disturbing any part of theframe and without removing the other sash; both of which may be raised, lowered, tilted, or

removedwithout causing them to protrude beyond the front stop of the upper sash; all of the operations being carried on entirely from the inside of the window, which is not only a great convenience to the workman but is a matter of the first importancewhen thewindow is provided with double sashes oris screened on the outside.

It will be understood that the mechanism for carrying out my improvements may be modified by substituting equivalents for the slide-bolts, stops guides and other accessories of the'sashes and frames, without departing from the spirit of my invention; and I do not desire to limit myself simply to the specific forms shown for these elements, the forms shown being used as illustrations of suitable devices forthe purposes int-ended. V q

A modification of the attachment for controlling the swinging of the uppersash may be made by attaching a chain 3l to an eye 32 in the 'topof the sash, the other end of the chain being fastened to a collar 30 which travels on a rod 29 fastened to the window stop outside of the sash. p As the sash is raised and lowered the collar 30 will slip up: and down therod 29, but the chain will arrest and hold the sash when it is tilted forward, as shown in Fig. 2. The chain is detachably secured to the rod through a hook, so that it may be readily disconnected if that is requisite forthe convenient manipulation of the sash.

Having thus described my invention, what I claim and desire to secure by Letters lPatent of the United States is V 1. The combination, with a window frame, having guide grooves in the sides thereof, of a sash having sash bottom guides and counterbalance chains traveling in said guideways, a slidable element embracing one ofsaid chains and a sash controller con-1 sash, whereby the sash may 'be-tilted at an,

angle to the vertical and raised and lowered while so tilted. V j V ELOF KLEONARD.
