STORM sAsH LOCKING DEVICE Filed Deo. 4, 1955 2 SheetS-Sheset 2 W//////////////{/ //W// /z e. JNVENTOR. ll. Q JoHN V. BRLINTFI United States Patent O STORM SASH LGCKING DEVICE Ohio, assignor to Storm John V. Balinti, Youngstown,

Ohio, a corporation of Sash, Incorporated, Girard, Ohio The present invention relates to sash locking devices, more particularly to a device for locking the outer sash of a double hung sash construction, and the principal object of my invention is to provide new and improved locking devices of the character described.

ln prior art double hung storm window constructions suitable latches have been provided for holding the inner and outer sashes in respectivepredetermined positions. However, particularly with metal sash constructions, it has been possible to unlatch the outer sash from the outside even though both inner and outer sashes were securely latched in respective closed positions. Obviously, this has been unsatisfactory since an intruder could easily gain access to the interior of a house unless the windows were securely locked.

My invention provides latch means for holding the inner and outer sashes in respective closed positions. Additionally, my invention provides means for automatically locking the outer sash in closed position when the inner sash is in closed position to prevent the outer sash from being unlatched from the outside. This and other advantages will become apparent from a study of the following description and from the drawings appended hereto.

In the drawings accompanying this specification and forming a part of this application, there is shown, for purpose of illustration, an embodiment which my invention may assume, and in these drawings:

Figure l is an elevational View of a double hung metal storm sash construction embodying my invention,

Figure 2 is an enlarged fragmentary sectional view generally corresponding to the line 2 2 of Figure 1,

Figure 3 is a reduced size, exploded perspective view of a portion of the outer sash illustrated in Figures l and 2,

Figure 4 is a perspective fragmentary view of the inner and outer sashes separated to better illustrate construction, and

Figure 5 is a reduced size fragmentary sectional view generally corresponding to the line 5-5 of Figure 2.

As illustrated, my invention is particularly, though not exclusively, adapted for use with double hung storm sash of metallic construction since this type of sash, because of space limitations, presents special problems in holding and locking the sashes in position.

As best seen in Figure 1, a conventional double hung storm window for a house or other structure comprises a frame which provides respective spaced-apart channels in which an outer sash 11 and an inner sash 12 are respectively slideable. As will be clearly understood, the storm window is adapted to overlie a conventional house window (not shown), the frame 10 usually being permanently secured to the casing of the house window by any suitable means.

ln the present embodiment and in the position of parts shown, the outer sash 11 comprises an upper member 13, a lower member 14, and side members secured together by any suitable means. The inner sash 12 comprises an ICC upper member 16, a lower member 17 and side members 18 also secured together by any suitable means.

In the embodiment herein illustrated, the sashes 11, 12, are glazed, any suitable arrangement being employed to secure a pane of glass Within respective sashes. As seen in Figures 2, 3 and 4, a groove 19 adapted to receive a pane of glass may be formed as shown in each of the members forming a respective sash. Any suitable means may be employed to sealably secure the glass in grooves 19, for example and as shown in Figure 2, a rubber gasket or the like 20 may be interposed between the sides of the grooves 19 and the glass for this purpose.

As in conventional double hung window constructions and when the storm window herein described is closed, the outer sash 11 is positioned adjacent the top of the frame 10 and the inner sash 12 is positioned adjacent the bottom of the frame. In this position of parts and as best seen in Figure 2, the lower member 14 of the sash 11 and the upper member 16 of the sash 12 are in overlapping relation but spaced apart by the respective channels in which the respective sashes are slideable (see also Figure 5). lt will be understood that the inner sash 12 may be moved in its channel from the closed position shown adjacent the bottom of the frame 10 to a position adjacent the top of the frame. The outer sash 11 may also be moved in its channel from the closed position shown adjacent the top of the frame 10 to a position adjacent the bottom of the frame.

ln order to close the gap between sashes 11, 12 when they are in closed position shown in Figure 2, the lower member 14 and the upper member 16 are provided with respective ribs 21, 22 which intert as shown to eifectively seal the storm window against drafts.

As best shown in Figures 2 and 3, the means provided for holding the upper sash 11 in the closed position shown or in other preselected positions comprises a bolt 23, a member 24 having a transversely extending portion 25, and a spring 26. The bolt 23 (see Figure 3) comprises a pair of axially aligned, spaced-apart portions 27, 28 connected together by a bight 29 for a purpose to appear. The spring 26, member 24, and the portions 27, 28 of the bolt 23 are slideably receivable between spaced-apart ribs 30 formed in the member 14. The bight 29 of the bolt 23 is notched at 32 adjacent portions 27, 28 in order to provide clearance for certain of the ribs 30, and although the bolt 23 is herein disclosed as being an integral structure, it may, if desired, be formed of separate pieces welded or otherwise secured together.

A side of the member 14 is notched out at 33 to provide operating clearance for the portion 25 of the member 24 and the member 14 is further cut away at 34 to provide for assembly in a manner to be disclosed.

At assembly, the spring 26, member 24, and the bolt 23 are adapted to be slid into position between the ribs 30 (in the order illustrated in Figure 3) until the spring abuts a pin 35 or the like (Figure 5) which extends across the channel 31 between the ribs 30. As illustrated in Figure 3, the member 24 will be so positioned that the transversely extending portion 25 extends downwardly, ortoward the open mouth of the channel 31, so as to permit the member 24 to slide between the ribs 30. Movement of the parts 23, 24 against the compression of the spring 26 will be continued until the portion 25 of the member 24 is aligned with the cut-out portion 34 of the member 14.

The member 24 will then be rotated to align the portion 25 with the notched out portion 33 and the spring 25 will then be permitted to shift the member 24 and the bolt 23 to the right until the portion 25 of the member 24 extends into the notched out portion 33 and until the portion 28 of the bolt 23 projects beyond the side member 15 of the sash. A pin 36 (see Figure 3) may be carried by the member 1,4 so ,that it extends across the channel 31 whereby engagement of the bight 29 therewith will prevent unintentional disassembly of the aforementioned part-s.

As shown in Figure 5, an aperture 37 is provided in the frame V1() for receiving the portion 2S of the bolt 23 when the outer sash 11 is in its uppermost position. As will be clear, the spring 26 will pres-s against the member Z4 which in turn presses against the bolt 23 'to urge the latter to seat in the aperture 37. When it is desired to shift the sash 11, the bight 29 will be grasped by the user and the bolt 23 shifted against the compression of the spring 26 until the bolt is withdrawn from the aperture 37.

Means are provided for preventing shifting movement of the bolt 23 without first raising the inner sash 12 and in the embodiment disclosed, a laterally extending abutment 3S is provided on the member te of the inner sash 12 adjacent the portion 25 of the member Zd. To prevent interference between the rib 21 and the abutnen't 33, thc rib 21 is cut away at 21a as shown in Figures 3 and 4. in the position of parts illustrated in Figure 5 wherein each sash is shown in respective closed position, interengagement between the abutment 33 and the portion Z5 of the member 24 will prevent withdrawal of the bolt 23 from the aperture 37. ln order to shift the sash 1li, it is tir-st necessary to raise the inner sash 12 so that the abutment 38 is moved through the opening 21a away from the portionv 25. The bolt may then be withdrawn from its aperture and the outer `sash 11 positioned as desired.

Although only one lower corner of the outer sash 11 and an adjoining upper corner of the inner sash 12 have been described and shown in detail, it is to be understood that the opposite lower corner of the outer sash 11 and the adjoining upper corner of the inner sash It). may be provided with structure identical to that hereinbetore disclosed. Additionally, while means have not been disclosed for locking the inner sash rin its closed position, any suitable well-known mechanism may be employed.

In View of the foregoing it will be apparent to those skilled in the art that i have accomplishedA at least the principal object of my invention and it will also be apparent to those skilled in the art that the embodiment herein described may be variously changed and modied, without departing from the spirit of the invention, and that the invention is capable of uses and has advantages not herein speciiically described, hence it will be appreciated that the herein disclosed embodiment is illustrative only, and that my invention is not limited thereto.
