WINDOW CLOSING DEVICE Filed June 12, 1929 7 b iii 29 a? 1 Patented Apr. 1, 1930 UNITED STATES FRED SCHIERGHOFER, OF MOUNT VERNON, NEW YORK Application filed June 12,

The main object of this invention is to provide a device whichis adapted to close a sliding windowat the time when it begins to rain so that the furnishings of a room of whlch the window forms a part will not become damaged or water-logged.

Another object of this invention is to provide a latch for retaining a window in open position until such time as it begins to rain when a paper ring mounted on the latch becomes soaked and weakened and parts, permitting the latch to operate to retract a latch bolt and permit downward movement of the window.

apparent in the description below, in which characters. of reference refer to like-named parts in the drawing. I

Referring briefly to the drawing, Figure 1 is a front elevational View of a window,

showing the application of the device.

Figure 2 is a front elevational view of a portion of the window sash showing the latching device mounted thereon.

Figure 3 is a side elevational view of Figure 2.

Figure 4 is an end-elevational View of Figure 2.

Referring in detail to the drawing, the numeral 10 indicates the sides of a window frame. These sides 10 are joined by a top frame member 11 and a similar lower member 12.

a pluralityof window sashes 13 having glass I panes 14 therein. Near the ends of themember 12 the frame hasps '15 are mounted thereon and theends of an elastic rubber rope l6 i has a bracket 18 mounted thereon by screws 19. This bracket 18 has a pair of spaced- The above and other objects will become.

WINDOW-CLOSING DEVICE 1929. Serial No. 370,264.

apart ears 20 projecting'downwardly therefrom through which aligned openings pass. The aligned openings in the ears 20 receive" a headed square stud 21. In the space between the ears 20' the upper end of a deformed 26 receives the flat finger-like extension 28 of a slidable locking bolt 29. The extension 28 has a pin 30 mounted thereon which is engaged in the slot 27 of the bell crank 24. The slidable bolt 29 is circular in cross section and is journaled in a lug 31 which is mounted on the side of the bar 17 of the window sash near the corner thereof. This slidable bolt 29- has its axis aligned with the axis of the stud 21, and the extension 28 of the slidable bolt 29 is provided with'an eyelet 32 to which one end of a coil spring 33 is attached. The opposite end of said coil spring is attached directly to the stud 21. The active end of said slidable bolt 29 is provided with a squared head 34 which, when in looking position, is adapted to normally be arranged as shown in Figure 2 so that one of the faces makes seating contact upon the flat shoulder of a triangular tooth 35 which juts outwardly from the side of the 'members 10. The lower end of the bar 22 and bell crank 24 are normally spaced-apart from each other when the spring 33 is extended, and to retain the sliding bolt 29 in projecting position, the bell crank 24 and bar 22 must be retained in the position shown in Figure 2. This is accomplished by slipping a paper loop or ring 37 over the ends of the bar 22 and bell crank 24.

paper, it will immediately become weakened and the spring 33 will overcome the resistance, fracture the ring 37 and retract the locking bolt 29 in the lug 31 toward the stud 21. This operation will remove the squared head 34 of the locking bolt 29 from seating contact upon the tooth 35 and, after being released, the 1llbl)8].;l0] 1 6 wil l,.pull the entire window sashdownwardly to closed position. Immediately, as the squared end of the locking bolt 29 is released from the tooth 35 the spring 83, which has in the course of assembly been slightly twisted, will rotate the stud 21 upwardly, thus rotating the entire mechanism one-hundred eighty degrees to a position above the window member 17 so that it will not interfere with the closing of the window.

It is to be noted that certain changes in form and construction may be made without departing from the spirit and scope of the invention.

I claim:

1. In combination with a window frame having slidable sashes therein, a window closing device comprising a tooth mounted rigidlyv on said frame, a bolt normally extended to engage said tooth to retain said window in raised position, yieldable means for retracting said bolt, and means engaging said bolt for retaining said yieldable retracting means and said bolt in extended position.

2. In combination with a window frame having slidable sashes therein, a window closing device comprising a tooth mounted rigid- 1y on said frame, a bolt normally extended to engage said tooth to retain said window in raised position, a normally suspended bar, a bracket supporting said bar in suspended position, yieldable means secured to said bracket and said bolt for retracting said bolt, and means pivotally mounted on said bar engaging said bolt for retaining said bolt in extended position to engage said tooth on said frame.'

'3. In combination with a window frame having slidablesashes therein, a window closing device comprising a tooth mounted rigidly on said frame, a bolt normally extended to engage said tooth to retain said windowin raised position, a normally sus pended bar, a bracket supporting'said bar in suspended position, a stud rigidly mounted on said bracket having said bar rotatable thereon, a spring, the ends of said spring being respectively attached to said stud and said locking bolt, said bar being adapted to be swung to the suspended position in a horizontal plane so that said bar does not become an obstruction in the closing of said window, and means connected to said locking bolt and'pivotally mounted on said bar for retaining said locking bolt in extended position.

4. In combination with a window frame having slidable sashes therein, a window closing device comprising a tooth mounted rigidly on said frame, a bolt normally extended to engage said tooth to retain said window in raised position, a normally suspended bar, a bracket supporting said bar in suspended position, a stud rigidly mounted on said bracket having said. barzrotatable thereon, a spring, the ends of said spring being respectively attached to said stud and said locking bolt,said bar being adaped to be swung to the suspended position in a horizontal plane so that said bar does not become an obstruction in the closing of said window, a bell crank engaging said locking bolt pivoted on said bar, and means engaging the ends of said bell crank and said bar for retaining said bell crank in a position to extend said locking bolt against the tension of said spring.

5. In combination with a window frame having slidable sashes therein, a window closing device comprising a tooth mounted rigid- 1y on said frame, a bolt normally extended to engage said tooth to retain said window in raised position, a normally suspended bar, a bracket supporting said bar in suspended position, a stud rigidly mounted on said bracket having said bar rotatable thereon, a spring, the ends of said spring being respectively attached to said stud and said locking olt, said bar being adapted to be swung to the suspended position in a horizontal plane so that saidbar does not become an obstruction in the closing of said window, a bell crank engaging said locking bolt pivoted on said bar, a moisture fracturable ring encircling the end of said bar'and said bell crank for retaining said locking bolt in extended position, said ring being adapted to part when moistened.

In testimony whereof I aflix my signature.
