FIG.

INVENTOR. HARRY A. WHALEY ATTORNEY United States Patent WINDOW MEANS Harry A. Whaley, Wichita, Kans. Application March 9, 1956, Serial No. 570,542

Claims. or. 20-55 This invention relates to windows. In a more specific aspect, it relates to'spaced and parallel moving windows, such as double hung prime windows and storm windows therefore which have portions which can be raised or lowered. In a still more specific aspect, this invention relates to latch means which can be used to join prime and storm windows together so that they can be moved together.

Double hung main or prime windows with an upper and a lower sash have long been known, and storm windows therefore have long been known in the art, the more convenient of which have a sash which can be raised or lowered so that ventilation can be had through the storm window, and the corresponding raised or lowered prime window sash. Also, means to connect the prime window sash and storm window sash are known, so that upon raising or lowering the prime window sash, the storm window sash will also raise or lower. These prior art means have their disadvantages. They are not convenient to use, since they are not designed to remain out of the way when not in connecting relation to the window members, and they do not provide for compensating for the weight of the storm window member on the prime window when they are connected together. The new latch means of my invention for connecting the prime and storm window sashes for movement together is very convenient to use; it does not interfere with window movement when not in connecting position; and it readily lends itself to compensating for the weight of the storm window member when the windows are in raised position.

I have invented means to join two spaced Window members for movement together. The new means of my invention has a retractable member mountable on one of the window members. Resilient means are employed which urge the retractable member to extended position. The retractable member is adapted when extended to engage the other window member whereby both window members are moved together when one of them is moved. In a preferred specific embodiment of my new connecting means, the retractable member is made so that when not in use it lays back against the window member on which it is mounted and out of the way. I prefer to do this by using a spring loaded hinge member which is mounted on one of the windows.

It is an object of this invention to provide new window means.

It is another object of this invention to provide new connecting means for joining together spaced and parallel moving prime and storm window members.

It is still another object of this invention to provide new latch means for connecting together the lower sash of a double hung prime window and a movable sash of a storm window therefor so that they will raise and lower together when the prime window sash is raised or lowered, such latch means being adapted to lay back out of the way when not in use and to compensate for the extra ice 2 weight on the prime window sash caused by operatively connecting the storm window sash thereto.

Other objects and advantages of the new window means of my invention will become apparent to those skilled in the art upon reading this disclosure.

Drawings accompany and are a part of this disclosure. The drawings depict preferred specific embodiments of the new means of my invention, and it is to be understood that such are not to unduly limit the scope of my invention.

In the drawings, Fig. 1 is an elevation view, in longitudinal cross section through the portion of the latch means having the retractable member, showing a preferred specific embodiment of my new latch means in open extended position.

i Fig. 2 is a side elevation view in cross section showing the latch means of Fig. I mounted and attached to window members in operative position.

Fig. 3 is a front elevation view of the latch means of Figs. 1 and 2 as mounted on the prime window sash.

Following is a discussion and description of the new window means of my invention made with reference to the drawings whereon the same reference numerals are used to indicate the same parts and/or structure. The discussion and description is of preferred specific embodiments of the new window means of my invention, and it is to be understood that such is not to unduly limit the scope of my invention.

The new latch means of my invention is a hinge member pivotally joined in approximately the middle portion by hinge pin 5. The end portion 7 of the hinge member has holes 9 therethrough which receive screws or bolts 11 to mount the latch on the lower sash of a usual double hung window having pane 15 and sill 17.

The other end of the hinge member is a hollow cylindrical housing member 19. A plunger latch member 21 is retractably mounted in housing 19. A spiral spring 23 which acts in torsion is mounted on pin 5 with one end in contact with housing 19 and the other end in contact with mounting end portion 7. This spring 23 acts to urge the hinge member to extended open position (the position of Fig. 1), so that when the latch means is mounted on sash member 13 and not in use it will lay back out of the way against sash 13. Spiral spring 25 is mounted in housing 19 with one end in a recess in plunger 21 and the other end backed by pin 5 and spiral spring 23. Spring 25 acts in compression to urge plunger 21 to extended position. Housing 19 has a closed slot 27 therein. A latch operator 29 attached to plunger 21 in any suitable manner projects out through this slot, so that by use of the fingers the plunger can be retracted. The forward edge of closed slot 27 catches operator 29 to retain plunger 21 in housing 19. The outer end of plunger 21 has a socket 31 therein to receive the boss portion 33 on the end of shaft 35. Shaft 35 is suitably attached to the storm window sash.

The openable storm window sash has a lower rail member 37 and a storm window pane 39. As is the usual case, the storm window sash has latch means 39 which pivot inwardly to release the storm window sash for raising the window. These latch means are reengaged when the window is raised to its desired height. It is preferred to tap these storm window latch means 39 and threadedly secure shaft 35 therein, as shown.

End portion 7 of the hinge member is mounted on sash 13 at a point so that whenplunger 21 is in extended position, and outwardly extended against the force of spring 23, boss 33 will engage socket 31 of plunger 21 with the storm window latch 39 in disengaged position. Thus, when sash 13 is raised or lowered, storm window sash 37 will raise or lower therewith. Latch operator 29 is used to retract plunger 21 sutficiently so that boss 33 and 3 socket 31 can be engaged, and, of course, operator 29 is used to retract plunger 21 to disengage the window latch means, and with such disengagement spring 23 forces housing 19 back out of the way against sash member 13.

With my new latch means it is then possible to open both the prime and storm windows by merely operating the prime window sash. This is very advantageous both in winter and summer for ventilation, eliminating one window raising operation. I have found my latch means to be of particular value because it conveniently moves out of the way when not in use, and spring 25 compression and/or size can readily be adjusted or varied to exert force on the windows against the window casings so that the windows will remain in desired position. Without a spring 25 exerting force on the windows, in many instances the extra weight of the storm window sash would make it impossible to keep the prime window in raised position with its means for such.

As will be evident to those skilled in the art, various modifications of this invention can be made, or followed, in the light of this disclosure and discussion, without departing from the spirit or scope of the disclosure or from the scope of the claims.
