AUTOMATIC WINDOW SHUTTER Filed Sept. 5, 1947 2 Sheets-Sheet 1 Patented May 9, 1950 UNITED STATES PATENT OFFICE AUTOMATIC WINDOW SHUTTER Arthur Hamilton, Harrisburg, Ark.
Application September 5, 1947, Serial No. '772,291
The present invention relates to automatic, window shutters and it consists in the combinations, constructions and arrangements of parts herein described and claimed.
It is an object of the invention to provide a device which may be attached to the conventional window frame which will automatically regulate the passage of air into' a room in accordance with the temperature thereof and the velocity of the wind which may be motivated by the outside air.
A further object of the invention is the provision of simple thermostatic means for regulating the position of a shutter with relation to a window.
Another object of the invention is the provision of a novel adjusting spring for counterbalancng the weight of a shutter in a device of the character set forth above.
A further object of the invention is the provision of a novel automatic operated latch for maintaining the shutter in a closed position dur-- ing a storm.
A still further object of the invention is the provision of novel means for adjusting the thermostat in a device of the character set forth.
Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawings, in which:
Figure 1 is a front elevational View of an embodiment of the invention in operative position upon a window,
Figure 2 is an enlarged sectional view taken substantially along line 2-2 of Figure 1,
Figure 3 is a fragmentary elevational View illustrating certain details of Construction,
Figure 4 is a sectional view taken along line 4-4 of Figure 2, and
Figure 5 is a fragmentary elevational view of an element of the invention.
Generally, there is provided a shutter which may be pivotally mounted at its upper end upon the outer side of a conventional window frame. A novel adjustable spring is provided for normally holding the shutter in an open posi-- tion. A thermostat is operatively connected to the shutter and is adapted to close the same upon the reaching of a predetermined low temperature and the shutter is also adapted to be closed by wind pressure overcoming the pressure of the spring regardless of the temperature of the air. A latch is provided whereby the shutter, once closed may only be opened from the inner side of the window.
Referring now more particularly to the draw- 1 Claim. (CI. 236-49) ings, ther is shown therein a shutter comprising a frame !O of generally rectangular Construction and having mounted therein a body of glass l l or other transparent material. The frame !0 is hinged, as indicated at !2, to a supporting frame- !3 which is adapted to be mounted in the lower section of a conventional window frame having an upper sash !4 and a lower sash !5.
In one side of the supporting frame !3 there is vertically mounted a thermostat comprising fluid operated bellows !6 having a vertically extending rod !l at its upper end to the upper end of which, as indicated at !8, is attached one end of a cable !9 which is trained over a pulley 20 carried by the framework !3 and the other end of this cable is attached to the shutter !0, as indicated at 2!.
To the lower end of the bellows is affixed a rack 22 which is enmeshed with a gear 23 carried by a shaft 24 which is revolubly mounted in journals 25 mounted upon the lower end of the framework !3. The shaft 24 extends horizontally toward the center of the framework !3 and is adapted to be revolved by a worm 26 operatively connected therewith and provided with an actuating handle 21.
A coil spring 28 having its convolutions on substantially the same plane as its inner end aflixed to a shaft 29 revolubly mounted in the framework !3 and provided at its outer end with a pointer 30 and an Operating handle 3!. A dial 32 is carried by the framework !3 in operative relation to the pointer 30. The outer end of the spring 28 is bent at an angle to form a foot 33 which is slidably engaged in a guideway 34 vertically mounted upon the inner side of the shutter.
Centrally mounted at the lower end of the framework !3 pivoted, as indicated at 36, is a latch having a hook 35 at its outer end which is adapted to be urged upwardly by a spring 3'! and which is provided with an Operating handle 38 at its inner end.
In operation, it will be seen that the spring 28 will normally urge the shutter to an outward position of approximately 45 degrees to the plane of the window. This is accomplished by adjusting the position of the spring and its tension by means of the handle 3!, the dial 32 being utilized for such adjustment. The thermostat is also adjusted at the same time as it is adapted to contract upon the lowering of the temperature of the air and hence exert a pull upon the shutter by means of the rod I'! and cable !9, which pull is contra to the outward exertion of the spring 28. Once adjusted, the sash !5 will of course be lifted in an opened position to allow air to enter therethrough. When, however, the temperature of the air becomes lowered the thermostat will act to close the shutter to a greater and greater degree until upon reaching a certain predetermined lower temperature the bottom of the Shutter will engage the hool 35 and automatically latch therewith. The latch may only be disengaged by manually Operating the handle 38 to again allow the shutter to moveoutwardly. It will also be seen that any undue draft of air passing through the window will cause a pressure upon the outer side of the Shutter thereby exerting a force against the action of the spring 28 and thereby cutting off such undue flow of air through the window. It will be seen that this action is independent of the action of the thermostat. The thermostat is controllable in its action by simply turning the handle 21 which, through the rod 24, gear 23 and rack 22, will act to efiectvely lengthen or Shorten the bellows !6 and hence vary the action of the same by the Shutter.
While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled in the art that many minor modifications may be made without departing from'the spirit of the invention or the scope of the appended claim.
What is claimed is:
A device of the character described comprising, a frame, a Shutter hingedly mounted on said frame for opening and closing movement, means on said shutter defining a guideway, an adjustable spring mounted on said frame and having a portion cooperating with said guideway for urging the Shutter to open position, a bellows type thermostat, a rod extending from one end of said thermostat, a cable interconnecting the rod and the Shutter, a rack extending from the other end of the thermostat, a gear supported on said frame and enmeshed with said rack, and handle-operated means for turning said gear whereby to move the Shutter irrespective of the action of the spring.
ARTI-!UR HAMILTON.
