AUTQMATIC wmnow CLOSER Filed Sept. 24, 1938 2 Sheets-Sheet 2 Inventor /0 7 "Fe Ze 7 PLzJQ/L Patented June 4, 1940 UNITED STATES PATENT OFFICE 1 Claim.

The present invention relates to automatic window closing devices and has for its primary object to provide a spring roller normally operating to close the Window and providing a strip 5 of disruptable material for holding the roller against the tension of the spring to normally secure the same against operation, said material adapted to be ruptured by rain or consumed by fire to release the roller to operate in closing the 10 window.

A further object is to provide an apparatus of this character of simple and practical construction, which is eificient and reliable in performance, relatively inexpensive to manufacture 15 and install in operative position and otherwise well adapted for the purposes for which the same i i is intended.

Other objects and advantages reside in the details of construction and operation as more 20 fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout and in which:

Figure 1 is a front elevational view of the 25 inside of a Window showing the same maintained in an open position.

Figure 2 is a fragmentary elevational view of the window taken from the outside thereof;

Figure 3 is a vertical fragmentary sectional 30 view through the window, and

I Figure 4 is a detail of the spring roller with parts broken away and shown in section.

Referring now to the drawings in detail, where in for the purpose of illustration I have disclosed 35 a preferred embodiment ofthe invention the numeral 5 designates a window frame Within which upper and lower sash 6 and 1, respectively,

are slidably mounted in the usual manner. To

the window sill 8 is secured a pair of spaced roller brackets 9 having a spring roller l rotatably supported thereon, one end of n the roller i being provided with a fixed trunnion ll rotatably supporting the roller in one of the brackets while the other end of the roller is provided with a recess l2 into which a shaft I3 is inserted and journaled in the end of the roller and forming a i rotatable support for said end of the roller.

A coil spring i4 is positioned on the shaft within the recess I2, one end of the spring being secured 5 to the shaft, as at l5, while the other end of the spring is secured to the roller, as at Hi, the shaft being secured to the adjacent bracket against rotation whereby it will be apparent that the rotation of the roller so as to place a ten- 55 sion on the spring M will cause a windingof the roller when thesame is released.

A flexible member l6, preferably of wire, has its ends secured to the roller, as at H, and its intermediate portion inserted through a pair of screw eyes l8 secured in spaced relation to the lower edge of the lower sash 1 of the window. 5

To the inside of the sill 8 is secured a spring clampis adapted to clamp one edge of a strip of paper 20 or similar disruptable material, the free end of the paper being Wound one or more times around the roller ID with portions of the 10 winding of the flexible member l6, as clearly shown in Figure 4 of the drawings, the strip of paper holding the roller against winding movement by the spring. One end of the paper strip is placed in abutting engagement with the ends of the member I6 which are connected with the roller and then the strip and portions of the member l6 are Wrapped together around the roller until finally the parts of the member it pass out of the side portions of the winding of the paper strip.

When securing the device in operative position, the window is raised andtemporarily held by means of a hook 2| secured to one side of theframe for engaging under the lower edge of the sash to hold the same against downward movement while the paper 20 is being positioned on the roller lll. After the paper has been placed in position, the hook 2| is released and the window willbe held in a raised position, against the action of the spring M by the paper 20. Should the, paper become disrupted or destroyed,

as by becoming subjected to rain or fire, the

roller ID will wind the flexible member l6" down-- wardly thus lowering the sash,

It is believed the details of construction and manner of operation of the device willbe readily understood from the foregoing without further detailed explanation.

Having thus described the invention, what I claim is: i A window closer comprising a spring roller, a

fixed mounting therefor, a flexible looped memher having intermediate portions attached to the window with its ends connected with the roller and having portions adjacent said ends wrapped about the roller, when the window is in open position, a strip of material pervious to moisture having one end wrapped about the roller and engaged by parts of the winding of the flexible member which holds said end of the strip to the roller and a clamp on the window frame for engaging the other end of the strip."
