SAFETY WINDOW. I

Application filed March 22, 1927. Serial No. 177,428.

This invention relates to windows of the type commonly used in home and building constructions and particularly to windows comprising upper and lower slidably mounted sections and has for one of its objects the provision of a window mounting adapted to permit both sections to be retained open at the same time thereby permittingthe maximum area of the opening in the wall of the building to be uncovered.

Another object of my invention is the provision of a pivotally mounted window section adapted to be suitably positioned to direct the draft of air passing through the window when open, and to allow a simple means of removing the window frame for repairing and replacing window panes.

Another object of my inventlon is the provision of a window mounting adapted to per? mit cleaning the windows from the inside of the house, thus eliminating the danger of sittingon the window sills.

A still further object of my invention is the provision of safety locking means for preventing the upper section of slidably mounted window sections from being lowered and abutted against the lower section thereof when the latter is rotated in open position.

Another object of my invention is the provision of safety locking means for preventing the lower section of a slidably mounted sectional window from being raised when the upper section thereof is rotated in open position.

A further object of my invention is the provision of a Window-comprising slidably mounted sections each of which may be rotated to open position.

Other objects will appear hereinafter, the

Fig. 3 is a transverse sectional view taken on the line 3-3 of Fig. 1.

Fig. 4 is a sectional view of the locking mechanism taken on the line 4-4 of Fig. 1.

Fig. 5 is a vertical sectional view of the locking mechanism taken on the line 5-5 I of Fig. 4.; and

Fig. 6 is a sectional view taken on the line 6-6 of Fig. 2.

Referring particularly to Fig. 1 of the drawing, the numeral 10 designates the window sash in which my improved window sections are mounted and the numerals 11 and 12 designate respectively, the upper? and lower ends of the sash 10. The upper and lower sections of the window, desigu nated by the

numerals

13 and 14, respectively, are mounted in the sash 10 in the usual manner with the lower window section positioned inside of the upper window section as shown in Fig. 2. Each of the window sections comprise an outer frame which is slidably mounted in the sash 10 in the cus tomary manner. The lower window frame 15 being provided with an inner frame 16 and the upper window frame 17 being provided with an inner frame 18. Each of the inner frames is adapted to hold a pane of glass 19, in the usual well-known manner of window construction. and is locked by suitable latches 16' and 17'.

The

inner frames

16 and 18 are pivotally mounted in the

outer frames

15 and 17 respectively, as shown in Figs. 1 and2. A bracket 20 comprising a socket is mounted on the upper end member of the inner frame 18. A second bracket 21 is mounted on the upper end member of the outer frame 17 directly below the bracket 20. The bracket 21 is provided with a stud or pin 23 which is journaled in the socket of the bracket 20. Similar pairs of brackets are mounted on the lower end members of the outer and

inner frames

15 and 16,'respectively. The bracket 24 is mounted on the lower end of the inner frame and is provided with a ends of the inner and outer frames of the lower window section are also connected with similar brackets as shown in Fig. 1, the bracket 27 being mounted on the upper end member of the inner frame having a projection or stud 28, journalcd in a socket of the bracket 29 mounted on the upper end member of the outer frame. As shown in Fig. 2, the lower ends of the inner and outer frames of the upper window section are also pivotally connected together by

brackets

30 and 31, respectively, it being understood that there is a projection 32 or stud mounted on the bracket 30 journaled in a socket in the bracket 31.

It should be understood that the above described construction pivotally supports the inner window frames in the outer window frames so that when the outer window frames are in the osition shown in Fig. 1, both of the inner rames may be rotated to open position thus permitting substantially the entire opening in the wall to be uncovered. Each of the inner window frames is pivoted independent of the other in their respective outer frames.

In the event that either the upper or the. lower inner frame is rotated to open position it is desirable that this rotation be effective in looking the remaining window section so that it cannot be lowered or raised, as the case may be, and jammed into the rotated inner frame. This locking operation is accomplished by the mechanism shown in Figs. 2 to 6 inclusive. It will be seen in Fig. 4 that the stud 25 extends through the socket of the bracket 26 and that the end thereof depends into a recess 32 An arm 33 is mounted on the end portion of the stud 25 and is rigidly secured thereto by a setscrew 34. This arm is disposed downwardly in the form of a hook at its outer end. The hook portion 35 of the arm 33 is disposed in an arcuate groove 36 in the lower end member 12 of the sash 10. This arcuate groove is under-cut as shown in Figs. 4 and 5 to provide a passage for the extremity of the hook 35. A slot 37 communicating with the under-cut portion of the arcuate groove 36 is provided in the lower member of the sash to permit the hook portion 35 of the arm 33 to be withdrawn from the under-cut portion of the arcuate groove 36 when the arm is in a predetermined position. It should be understood that when the inner frame is rotated to closed position the hook 35 is positioned in registration with the slot 37 and the outer frame is free to be raised, but when the outer frame is rotated to open position the hook is out of registration with the slot, and the outer frame is restrained from being raised. The upper end of the up er window section is provided with simi ar locking means and in view of the identical construction thereof, it is not thought that a. duplicate description is necessary.

The stud 32 mounted on the lower end of the upper inner window section as shown in Fig. 6 is provided with a semi-circular plate 38 having a slot 39 therein. This plate is rigidly mounted on the end of the stud 32 which extends through the end member of the outer frame 17 and is adapted to rotate in unison therewith. An arm 40 is rigidly mounted in the stud 28 of the upper member of the inner frame of the lower window section and is adapted to extend beneath the. plate 38. It should be understood that both the plate 38 and the arm 40 rotate in unison with their respective studs and that the studs rotate when the inner frames are rotated. Thus when the frames are in closed posit-ion as shown in Figs. 1 and 2, the arm 40 is in registration with the slot 39 and the sections may be raised and lowered relative to each other. but when either inner frame is rotated to open position the arm and slot are moved out of registration with each other and neither of the sections may be raised.

Having thus fully shown and described an embodiment of my invention, what is desired to be secured in Letters Patent of the United States is:

1. A window comprising up er and lower slidably mounted window fi'ames, inner frames concentrically mounted within said upper and lower slidably mounted frames, pins rigidly mounted on the end members of said inner frames and journaled on the end members of said slidably mounted frames for pivotally attaching said inner frames to said slidably mounted frames, 0. plate mounted on the end of the lower pin of said upper inner frame having a slot therein, and an arm mounted on the upper pin of said lower inner frame adapted to engage said plate, said arm and said plate being adapted to rotate in unison with the respective pins to which they are attached, said arm being positioned to register with the slot of said plate when both the inner frames are in closed position to permit raising and lowering of said slidably mounted frames and adapted to engage said plate when either of said inner frames is rotated to open position for preventing raising or lowering of said slidably mounted frames.
