Referring to the drawings in detail, Figures 1 to 7 inclusive show one form of the invention as applied to a rectangular window frame generally designated I of channel or Z-bar formation in cross-section, including side frame members I06 having flanges I01, and the sash frame members or bars I06 are connected at their tops and bottom by horizontal cross rails (not shown).

A series of window sashes are adapted to be supported by the rectangular window frame I05 and are generally designated I08. The window sashes I08 are arranged in superposed relation one above the other to swing vertically on horizontal pivots to facilitate the opening and closing thereof.

Each of the window sashes I08 is formed of side rail portions I09 connected at the top and bottom by horizontal rails H8 and III respectively. The side, top and bottom rails are formed of suitable bar members of Z or channel section welded together at their ends or otherwise suitably fastened, and are adapted to support glass panel members H2.

Secured to the upper portion of the sash side rails I09 at each side of the window sash is a hinge bracket II3 which is fastened in place by rivets or the like I I4. A hinge plate I I5 is welded as at H6 to the flange I01 of the side rails I06 (Figure 4) and said hinge bracket H5 is provided with a suitable opening adapted to register with an opening in the upper end of the hinge bar I I5 for receiving a hinge pin III. In this manner, the sash members I 08 are hinged at their upper ends to the Window frame I85 to swing vertically on the horizontal pivot pins III.

In order to operate the window sashes I08 in unison, a slide bar generally designated H8 is slidably connected to the web portion of the side rail I06 by suitable pin and slot connections and it is to be noted that the slide bar I I8 is composed of bar sections I I9 having ofiset overlapping end portions I20 for being connected together by screws or the like as at I2I. Each of the slide bar sections H9 is provided with an elongated slot I22 which is adapted to be guided upon a guide screw I23 threaded in a suitable opening I24 in the web portion of the side rail I06.

Anchored to the screw pins I23 is an operating lever I25 which is provided with an offset portion I26 so that the free end of the operating lever may be slidably connected to the side bars I09 of the window sash I08. The slidable connection for accomplishing the above, includes a slide guide comprising a base portion I2'I having upwardly and inwardly extending flanges I28. The

base plate I2! is fixed in place by suitable screws T or the like I29. The extreme free end of the pivoted operating lever I 25 is bent or offset as at I30 to provide a slightly rounded guide portion I3I adapted to be received between the inwardly extending flanges I28 and be slidably guided therein.

The pivoted operating levers I25 are adapted to be connected to the slide bar I I8 by means of linkage I32, one end of which is pivoted to the side bar by means of a. pivot pin I33 while the opposite end is provided with a pivot pin I34 having flattened side portions I35. The pivot pin I34 is anchored to the end of the linkage I32 in such a manner as to be rigidly secured thereto, and as shown in Figure 1, the pin I34 is riveted in place. The pivot pin I34 is adapted to operate in a keyhole slot I36 formed in the operating lever I25 so that after: the slide bar II8 has been moved upwardly a slight amount to disengage a pair of mutually engaging cam surfaces, the same will be received in the circular portion I31 of the keyhole slot I36 so as to permit free relative movement of the pivot pin I34 with respect to the pivoted operating lever I25. Secured to the pivoted operating lever I25 adjacent the keyhole slot I 36 is a cam pin I38 which is adapted to be received in an obliquely extending slot I39 formed in the link I32 substantially intermediate the ends thereof. The cam pin I38 is rigidly affixed to the operating lever I25 by being riveted thereto as at I40.

Suitable operating mechanism may be provided for the slide bar I I8, such as a conventional rack and pinion drive, and it is to be understood that the sash frames I08 are slightly distorted or canted so as to permitthe operating slide bar I I8 and sash connecting linkage to move the opposite edge of the window sash into engagement with the window frame I05 prior to the engagement of the flanges of said sash member I08 on the side adjacent the operating mechanism. It is intended to provide a locking bar on the side of the window sash I08 opposite the operating mechanism, so that the projections thereon will engage the keeper members carried by the lower swinging end of the side sash rails I09. An operator for controlling the slide bar may also be incorporated in the window frame structure to securely lock the swinging sash member I08 in position when closed.

Operation It will be assumed that the window sashes I08 are in their fully closed position, and that the locking means on the sides thereof opposite the operating mechanism is in its latched position. The operating mechanism will assume the position shown in Figures 1 and 2 and by releasing the locking mechanism on the opposite side of the window sash, the slide bar I I8 may be raised or elevated by means of the control therefor such as the conventional rack and gearing mentioned above. During the initial upward movement of the slide bar H8, the square sided pivot pin I34 will travel upwardly toward the round portion I31 of the keyhole slot I36, so that the mutually engaging cam surfaces I38 and I39, upon continued travel of the slide bar H8, will exert an outward force on the sash members I08 and cause the same to swing about the hinge pins I I! as shown in Figure 3. As this occurs, the pivot points I23, I33 and I34 (which, it is to be noted, are in lineFigure 2) will be moved offcenter by the outward exertion created by the mutually engaging cam surfaces I38 and I39 so as to break the pivot points and throw the same off dead-center to thereby permit the sash members I08 to be raised to various positions of adjustment. The slide bar H8 will be held in its adjusted position by the manual control mechanism including the rack and pinion connection and the sash members I08 may be retained in their predetermined opened position. v

When the slide bar H8 is moved downwardly in a direction to close the sashes I98 and swing the same horizontally about their hinge pins I II, the links I32 swing the operating levers I25 inwardly until the flat-sided pin I34 is in registry with the elongated portion of the keyhole slot I36. As this occurs, the cam pin I38 will be received in the obliquely arranged cam slot I39 in the links I32 so that continued downward movement of the slide bar I I8 will cause the mutually engaging cam surfaces of the slot and pin to exert an inward force or pressure on the sash members I98 and swing the same inwardly against the window frame I95. As mentioned above, the opposite side of the window sash 38 will have engaged the window frame W35 prior to the exertion of the final closing force imparted to the operating mechanism side of the window sash. As the flattened pivot pin I34 travels downwardly in the elongated portion of the keyhole slot I36, the window sash will be locked at the operating mechanism side thereof against outward swinging movement, and by manipulating the locking mechanism at the opposite side of the window sash I98, the entire sash members will be securely locked at each side thereof to the window frame I95.

The uppermost vertically swinging sash member I08 in the window frame I95 is adapted to be provided with a hinge connection so as to permit the uppermost sash member to be swung to a position to facilitate swinging of the sash panel member II2.

In certain window constructions, it may be desired to provide an operating mechanism at each side of the Window frame, and in this event, the window operating structure mentioned above may be duplicated at each side thereof with operating ears connected by a horizontally extending torsion bar so that operation of one of said gears I6 by means of a control handle will cause rotation of both gears and the operation of the sash operating bar at each side of the window frame.

It is to be understood that the forms of the invention herewith shown and described are to be taken as preferred embodiments of the same and that various changes may be made in the shape, size and arrangement of parts without departing from the spirit of the invention or the scope of the subjoined claims.
