PROJECTED WINDOW.

Application filed July 14, 1927, Serial No. 205,703, and in Japan December 30, 1926.

My invention relates to improvements in windows of the type comprisinga swinging sash provided with horizontal axes pivotally and slidably mounted on rails and a sliding sash provided with counter balances.

The object of the invention is to provide a novel operating mechanism for windows of this type whereby said swinging and sliding sash may be operated independently of each other or co-operatively keeping the sliding sash at a desired position.

According to the present invention a chain or rope mounted on a pulley is connected at one end to the swinging sash and is connected at the other end to the sliding sash by detachable coupling means. A hand rope attached at the lower side of the swinging sash is passed over a guide pulley arranged 0 on the upper end of the sliding sash and a of the swinging sash. The sashes are closed by pulling the lower one of the hand ropes and opened independently or jointly according to whether the first mentioned chain or rope is in engagement or disengagement with the coupling means to the sliding door by pulling of said second hand rope.

The invention is more particularly illustrated with reference to the accompanying drawing in which Fig. 1 is an elevation of the improved window as closed and seen from inside.

Fig. 2 is a sectional side elevation of Fig. 1.

Fig. 14 is a plan view showing the operation of the modified coupling mechanism.

Referring more particularly to the drawing the window frame (1) is provided at the upper part of its sides with vertical rails and the upper sash on its adjacent sides and spindles or axes (4) (4) provided atone end with shoe guides that are slidably mounted on said rails (2) (2) as shown in Figs. 8 and 4. The otherend of said aXes are pivoted to the sides of the swingng sash (3) so that the latter can be proected outwardly as shown in Figs. 6 to 9. The sash (3). is provided at its sides with pivoted supporting links (5) (5), the lower end of said links being also pivoted'to the frame (1) so that when the sash (3) is closed said links (5) (5) are slightly'inclined outwardly as is shown in Figs. 2 and 3.

A grooved pulley (7) is arranged in a recess. (6) formed at the central part of the top of the window frame (1), and a chain or One end of said rope (8) is connected to the upper end of the swing sash (3) and the other end is connected to a coupling piece (10) provided with a grooved pulley (11) on a bracket, the purposes of which will be more particularly pointed out hereinafter. A

sliding sash (9) is provided with the usual counter balances (12). The upper side of the sliding sash (9) is grooved and provided with a seat (13) and a screw bolt (14) between which the aforesaid coupling piece (10) can be clamped so that the swinging sash (3) and sliding sash (9) may be coupled to each other through the chain or rope (8) or may be uncoupled by unscrewing the bolt (14).

The swinging sash (3) is further provided with hand ropes (15) and (16), the upper one (15) hangs freely insidethe sash and the lower one (16) after passing over the guide pulley (11) on the coupling piece (10) also hangs inside the sash. The free ends of said ropes (15) and (16) can be connected to each other as is shown in Fig. 1.

A transverse frame member (17) extends across the window frame (1) between the swing sash (3) and the sliding sash (9), and a guide rod 18) is vertically fixed between said transverse frame member (17) and the top of the frame (1). The coupling piece (10) provided with a guide tube (19) slidably fitted on said guide rod (18) so that the coupling piece may run smoothly on the rod (18) when the sashes (3) and (9) are opened or closed. Said guide tube is preferably provided with a set screw (not shown in the drawing) whereby the tube may be clamped on the guide rod (18) at the time of the closure so that the sashes may be locked.

In case of necessity, the window may be divided into three parts; the upper part of which being provided with the swinging sash the lower part with the slidin sash (9) and the central part with a fixed sash in such a manner that the upper sash is situated by turn outside of the lower sash when the window is closed. frame member (17) is removed and the guide rod (18) is fixed on the fixed sash.

The operation of the improved window is as follows -When the coupling piece (10) is connected to the sliding sash (9) as shown in Figs.- 2

and 3, and the sliding sash (9) is moved upward the swinging sash moves downward on the rails (2) by its own weight and the lower side of the swinging sash is pushed outward by the arms (5) (5) so that the sash (3) is projected and the lower side of the sliding sash is opened to form air passages at the upper and lower parts of the window as shown in Fig. 6.

Further movement of the sliding sash (9) does not affect any movement of the swinging sash, and the sliding sash can be raised to any desired height as is shown in Fig. 7. When the lower rope (16) is pulled by hand when the sashes are in the position shown inFig. 6 or Fig. 7, the coupling piece (10) is pressed downward by the guide pulley (11) which causes the sliding sash (9) to be closed and at the same time the swinging sash (3) is pulled upwardly at its lower end and is as a whole moved upwardly and is closed as shown in Figs. 2 and 3. The guide tube (9) may be then clamped on the guide rod (18) and the sashes may be locked in their closed position.

When the coupling piece (10) is uncoupled the rope (8) slackens and the swinging sash is projected by its own weight or by aid of the upper hand rope (15) pulled downward as shown in Fig. 8. Thus the swinging sash (3) may be opened. while the sliding sash (9) is kept closed. The swinging sash may be closed by pulling the lower rope (16'). The sliding sash (9) may be opened or closed independently of the swinging sash (3) when the coupling piece (10) is uncoupled as shown in Fig. 9.

The coupling means may be modified as shown in Figs. 10 to 14. A pair of endless chains or ropes (20) (20) are passed on In this case the transverse grooved pulleys (21) (22) arranged at both sides of the window frame (1). The pivotal axes (4) (4) of the swinging sash are fastened to one side of said ropes (20) and on the other side (20) of said ropes are adjustable collars (23) (23). The sliding sash (9) is provided at its upper side with a tri-. angular cam (24) projecting its axis (25) inside the sash and provided with a finger piece (26) at its end. ranged at one side of said cam to prevent the free rotation of the latter. The cam (24) is provided with rods (28) (28) slidably passing through guides (29) (29). The other ends of the sliding rods (28) (28) are forked at (30) (30)v and said forked ends project at the other sides of the endless rope (20) (20). i

shown in Fig. 13, the forked ends (30) (30) are disengaged from the endless ropes (20) (20) and the swinging sash may be opened irrespective of the sliding sash (9) by pulling the upperhand rope (15)-so that said sash is projected "outward. to form an air passage at the upper part of the window as shown in Fig. 11. The sliding sash (9) ing sash (3) to a desired position to form an air passage at the lower part of the wmdow.

The sashes are closed by pulling the lowerv hand rope (16) whereby the swinging sash (3) is pulled upward and at the same time the sliding sash (9) is pressed downward so that they may be closed as shown in Fig. 12.

When the cam (24) is rotated to the position shown in Fig. 14, the forked ends (30) (30) of the sliding rods (28) (28) are brought in engagement with the endless ropes (20) (20) at the collars (23) (23) so that the sliding sash (9) becomes coupled to the swinging sash (3) and they may be. opened or closed co-operatively as stated be- A spring (27 is ar- When the cam (24) is kept in the position may also be opened irrespective of the swingconnecting one end of said chain or rope to said swinging sash, means for detachably connecting the other end to said sliding sash, said other end carrying a pulley, hand ropes secured to the top and bottom of said swinging sash the lower one of which passes over the guide pulley arrangedon said chain or rope, substantially as described.

2. In the improved projected window, a swinging sash and a sliding sash, pulleys arranged at the upper and lower ends of the window frame at both sides and a. pair of endless chains or ropes vertically passed thereon one for each pair of pulleys, each endless chain or rope connected to apivotal axis of the swinging sash, adjustable collars secured to said endless chains or ropes, forked sliding rods secured on said sliding sash, cain means to operate said sliding rods to stantially as described.

In testimony whereof I have aflixed my signature.
