WINDOW WITH WINGS. ADAPTED TO BE OPENED OUTWARD AND INWARD.

To all whom "it may concern:

Be it known that I, CARL AUeUs'r VALCII- NER, a subject of the German Emperor, and resident of Frankfort on the Main, Germany, have invented certain new and useful improvements in Windows with \Yings Adapted to Be Opened Outward and Inward, of which the following is a specification.

The well known wing windows, in which the wings are opened by rotation, are secured by means of hinges to the window frame. In opposition to this well known arrangement of the wing motion, the window which forms the subject matter of the present invention, is provided with tubular hinges which are secured by means of screws to the base and the top edge of the window. Owing to this arrangement not only an easy motion of the wings outward and inward is obtained but also the lowering thereof in the hinges is prevented.

In the annexed drawings: Figure 1 is a front elevation view of the closed window; Fig. 2 is a vertical section through the closed window; Fig. 2 is a vertical section of same in an open state; Fig. 3 is a top plan view of the closed window; Fig. 3 is a similar view of same opened; Fig. 4 shows a vertical section on line a.b of Fig. 6 Fig. 5 is a similar section on line cd of Fig. 6. Fig. 6 shows a horizontal section on line ef of Fig. 4 the window being closed. Fig. 7 is a vertical section on line gh of Fig. 9. Fig. 8 shows a similar section on line ik of the same figure. Fig. 9 is a horizontal section on line Zm of Fig. 7 the window being open. Fig. 10 is a front elevation view of the device for raising and lowering the carrying beam, the window being closed. Fig. 10 shows a similar elevation view of the same device, the window being open.

My improved window comprises the window frame A, the carrying beam B, the upper cross beam 3, the lower wings D, the upper wings E, the tubular hinges F, the tightening bars G and the window locking mechanism H provided with the actuating handle I (Fig. 1-3).

By raising the carrying beam B the lower wings D are pressed against the upper cross beam C and are held in place by a feather and groove joint (Z without the use of basquill bolts or similar closing devices. At the same time, a wind and water tight joint is secured. \Vhen the carrying beam B is lowered the wings D owing to their own weight also de- Specification of Letters Patent.

scend they must however find a bearing point with a view of allowing rotation, when they have been lowered a height correspond ing to that of the upper engagement (Z (Fig. 8) increased with a certain play :t' (of about 3mm.) while the carrying beam B has still to be lowered afterward the same distance. After this motion is finished, the wing D is freely suspended between the carryii'ig beam B and, the upper cross beam C and can thus be swung inward and outward. This oscillation of the wings is rendered possibleby the lower and upper tubular bearings F in which the pivotsfof the window wings D are adapted to oscillate and to slide (Figs. l, 5, 6, 7,8). The lower tube F bears with the plate f on the lower part of the window framework A and passes through the carrying beam B. This passage is necessary .in order to allow the carrying beam B to continue its descending motion without the wings 1) following it. The pivotf of the upper hinge is so long that after the lowering of the wings I) it remains still far enough engaged in the tube F (Figs. 7 and 8) for allowing the rotation of the wings.

At the place where the lower tube F passes through the carrying beam B, a covering platef is arranged which at the same time serves as a bearing for the tightening lath G (Figs. 4, 7).

The longitudinal axis of the tubular hinges is a little farther removed from the window frame A than half the thickness of the wood I) of which the wing is made, so that the wing may be opened more than 90 (Fig. 6). The window wing engages the window frame A in the well known manner with its longitudinal edge which is rounded according to an arc of a circle having the axis of oscillation of the window wing as a center (Figs. 6 and 9). The thus formed joint is preferably engaged, in order to realize a better closure, by a tightening device which is formed by a. tightening lath G engaged into the frame A and which when the carrying beam B is raised is disengaged from the frame A by the covering plate and the oblique slots g, 9 provided in the lath (Figs. 4 and 6) and is again drawn into the said frame when the carrying beam B is lowered (Figs. 7, 9). The carrying beam B itself is raised and lowered by means of a device H (Fig. .l) which is composed of two or more supporting members it adapted to be folded down like hinges and connected. together by means of a connecting rod 7t (Figs.

10, 10). The righting and knocking down of these supporting members an d consequently the raising and lowering of the carrying beam is effected by the connecting rod 7L being reciprocated by means of a crank 7L3 and an intermediate rod 7t.

Having now fully described my said invention, what I claim and desire to secure by Letters Patent is:

1. in a window the combination with the window frame and the windoi r wings of a carrying beam, vertically movable in the said window frame, a tongue and groove joint between the upper edge of the wing and the upper cross beam of the frame, and the lower edge of the wing and the upper edge of the carrying beam, a tubular bearing in said up per cross beam, a vertical pivot secured to the said win and rotatably and slidably engaged in said tubular bearing, a lo ver tubular bearing passing through the said carrying beam and resting upon the lower part of said frame, and a lower pivot secured to said wing and rotat ably and slidingly engaged into the said lower tubular bearing and means for raising and lowering the said carrying beam, substantially as and for the purpose set forth.

2. In a window the combination with the window frame and the window wings of a carrying beam adapted to vertically move in said window frame, interlocking means provided between the upper edge of said window wing and the lower ecge of the upper cross beam of said window frame, interlocking means provided between the lower edge of said window wing and the upper edge of said carrying beam, a vertical tubular bearing provided in the said upper cross beam of the frame, a vertical pivot secured to the upper edge of said wing and rotatably and slidingly engaged in the said tubular bearing, a lower tubular bearing vertically resting upon the lower cross beam of said window frame and crossing the said carrying beam, a vertical pivot secured to the lower edge of said wing and slidably and rotatably engaged into the said lower tubular bearing, a plurality of folding carrying members arranged between the said carrying beam and the lower cross beam of said window frame, a connecting bar between these members, and a crank mechanism adapted to reci )rocate the said connecting bar, substantia 1y as and for the purpose set forth.

3. In a window of the kind described, the combination with the window frame and the window wings of a carrying beam mounted so as to be vertically movable in the said window frame, interlocking engaging means arranged at the top and bottom of said window wings, means for raising and lowering the said carrying beam, a vertical groove in each of the side members of said window frame, a corresponding groove arranged in the adjacent edge of the said window wing, a tightening lath engaged in the said groove of the frame and adapted to engage also the groove of the wing, this tightening lath resting on said carrying beam and adapted to be vertically shifted thereby, oblique slots in the said tightening bars and pegs secured to said frame and adapted to engage the said slots, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of two witnesses.

CARL AUGUST WALCHNER.
