2 Claims. (Cl. Ztl-55) This invention relates to windows of the double sash sliding type and particularly to mechanism adapted to connect the inner sash to the outer sash in such a manner as to cause the outer sash to be closed automatically when the inner sash is closed.

Heretofore in air conditioned or heated homes, apartment houses and other buildings where independently slidable outer and inner sashes are used, much of the insulating value of outer sash has been lost because of the failure of the occupants of the buildings to close the outer sash when the inner sash is closed, after both have been opened. Failure of the tenants of apartment houses to close the outer sash is particularly troublesome and expensive for the landlords who furnish air conditioning service or fuel for heating the building because the tenants or guests frequently, after opening the windows of sleeping quarters at night, fail to close the outer or storm sash when the inner sash is closed for daytime occupancy.

The present invention has for its principal object to provide for windows of the class described simple and readily attachable means for automatically actuating the outer sash to closed position when the inner sash is closed.

Another object is to provide an attachment of the class described which may be securely and easily fastened in operative relation to both sashes during the winter or other season when the insulating value of the storm sash is needed and readily removed when the storm sash is not needed.

A further object is to provide an attachment of the class described which guards against the unauthorized opening of the outer sash when the inner sash is locked in either closed or slightly open position.

My invention also includes certain other novel features of construction which will be more fully pointed out in the following specification and claims.

The invention will be best understood by reference to the accompanying drawings which illustrate, by way of example and not for the purpose of limitation, a preferred embodiment of my invention.

In the drawings:

Figure 1 is an inside elevational view showing my device in connection with a sliding sash window of common type and with portions of the inner sashes broken away to show the outer sash and connecting members;

Fig. 2 is a vertical sectional view showing the window in closed position and with my improved attachment in place thereon;

Fig. 3 is a typical horizontal section through the window, showing the sash connecting members in plan view;

Fig. 4 is a front elevational view showing a pair of the connecting members and carrier bar separate from the window;

Fig. 5 is a top plan view of the connecting members and carrier bar and with an end portion of the bar shown in horizontal section, and

Fig. 6 is a fragmentary, horizontal sectional View taken approximately on the line 6-6 of Fig. 3.

In the drawings a window of conventional type is shown ited States atent Cil ice

as having a frame indicated generally by the numeral '7, a sill 8 and inner and outer vertically sliding sashes. Each of these sashes has upper and lower relatively slidable members. The lower inner sash, indicated generally by the numeral 9, has a lower rail 10 and an upper rail 11 and is guided in the usual manner between stop and parting members 12 and 13 (Fig. 3). Similar guides are provided for the upper member 14 of the inner sash.

Mounted in outwardly spaced relation to the inner sash is an outer or storm window having a lower sash 15 and an upper sash 16 which are slidable vertically between suitable guides indicated generally by the numeral 17. This window is of a conventional metal type including a storm sash and a screen. The outer sash 15 has a bottom rail 18 and stile members 19 litting in the guides 17. The upper sash 16 may be mounted in a common plane with a screen 20 in conventional manner.

Pairs of connecting

members

21 and 22 are provided to operatively connect the inner sash 9 to the outer sash 15. The members 21 are strong, rigid arms fastened at one end to the lower rail 18 by means of a bar 23 which is preferably formed with a channel 24 extending along its upper edge to receive the lower marginal portion of the rail 18. The bar 23 is also formed with a bottom channel groove to receive a flange 25 formed on a fixed lower frame member 26 of the outer window frame. Mounted centrally on the bar 23 is a lock 27 adapted to be actuated by a removable key 28 (Fig. 5) to fasten the bar to the lower rail 18 of the sa'sh 15. A keeper 29 is fastened on the rail 18 to receive and interlock with the bolt of the lock 27.

As best shown in Figs. 4 and 5, the bar 23 carries at each end a latch pin 30 which is spring biased to project into apertures formed in the vertical guides 17 of the outer sash. A handle 31 projects from each of the pins 36 through an elongated slot 32 formed in the inner side of the bar 23. The slots 32 are approximately L-shaped, having vertically extending portions 32a into which the handles 31 may be moved to retain the latch pins 30 in retracted, inoperative position.

As viewed from the side, the connecting members 21 are substantially Z-shaped and have end portions 21a which are rigidly secured to the bar 23. The opposite end portions 2lb of the members 21 project beneath the connecting members 22 which are rigidly fastened to the rail 10 by brackets 33 carried by the end portions of the rail. A bracket 33 may be formed integrally with each of the members 22 and may be secured to the rail 10 by means of screws or other suitable fastening members, as indicated in Fig. 6. It will thus be evident that the connecting members 22 project into the path of the inner end portions 2lb of the members 21 so that when both sashes are in open positions and the inner sash 9 is moved downward to closed position, the connecting

members

21 and 22 are operative to close the outer sash 15.

To install my attachment on sliding sashes of the common type described, the bar 23 carrying the connecting members 21 is placed in engagement with the lower marginal portion of the rail 18 and fastened in engagement therewith by operation of the lock 27, whereupon the key 28 may be removed to guard against unauthorized removal of the outer sash attachment. The connection between the outer and inner sashes is completed by fastening the brackets 33 carrying the members 22 to the outer surface of the rail 10 in proper vertical alignment with the inner end portions 2lb of the members 21. In cases where it is desirable to provide for the locking of the outer sash 15 in closed and/ or partially open positions, the side guide members 17 for this sash are drilled at suitable intervals to provide sockets to receive the outer ends of the pins 30. This makes it possible to lock the outer sash with its bottom rail either in fully closed position or at any selected elevation, e. g., that indicated in broken lines in Fig. 1.

ln operation, the inner sash member 9 may be raised to any open position, in the usual manner, without regard to my device because my connecting members 22 are separate from the members 21, Aft'er moving the inner sash to open position, the outer sash may also be raised to corresponding open position or to any position at a lower elevation in the usual manner. if the latch pins 3) are used to lock the outer sash in closed or other selected position, these pins may be actuated to retracted position to permit opening of the outer sash by manipulation o the handles 31. Subsequently, when it is desired to close the window, the latch pins may be retracted from their operative position and the inner sash 9 moved downward to closed position in the usual manner thereby automatically, by operation of the connecting

members

21 and 22, closing the outer sash 1S. It will be evident that with my attachment properly installed, the inner sash cannot be closed without closing the outer sash also.

My attachment constitutes a safeguard against the unauthorized opening of both sashes from the exterior of the building when the inner sash is suitably fastened in either closed or slightly open position.

When the insulating value of the outer or storm sash is not required, the members 21 connecting the outer sash to the inner sash may be quickly and easily removed after merely operating the lock 27 to disconnect the bar 23 from the rail 18.

I claim:

l. For a window having outer and inner sliding sashes and first and second rail members of the respective sashes disposed in parallel relation one to the other, an attachment comprising, a rigid bar adapted to extend along and in contact with the first rail member, said bar being laterally coextensive with said rail member, means for detachably fastening said bar to said first rail member, a first pair of rigid connecting members projecting from said bar toward the inner sash at widely spaced points along said bar, and a second pair of connecting members carried by the second rail member and projecting therefrom into the path of said connecting members of the first pair whereby said outer sash may be actuated to closed position when the inner sash is closed.

2. For a window having outer and inner substantially vertically sliding sashes and rst and second lower rail members of the respective sashes disposed in parallel relation one to the other, an attachment comprising, a rigid bar formed to t in engagement with said lirst rail member and being laterally coextensive therewith, means including a lock having a removable key for detachably fastening said bar to said first rail member, a first pair of rigid connecting members projecting from said bar toward the second rail member, and a second pair of connecting members carried by the second rail member and projecting therefrom into the path of the connecting members of said first pair whereby said outer sash is actuated to closed position when the inner sash is closed.
