.v n This invention relates to improvements 1n automatic closers forwindows and the like,

and the primary object of theinvention is.

15 It is common to open windows in rooms before retiring at night, and dierent types' Aof devices have been constructed for automatically closmgthe windows, but so far as I am aware, these devices have not come 20 into general use.

kOne object of my present invention is to l construct a device for the above described purpose that is' comparatively cheap and Ysimple in construction and `easily applied to any window. 'l

Another object of the invention is to provide the device with a manually operated means for charging it, and holdin@ the window open and for releasing the charge and releasn the holdingmeans for the window, the win owv then being automatically closed. Further objects of the invention will api pear-from the following description:

. Figurel isa side elevation of my iinproved automatic window closing device, the same being shown attached to a window sill and in conjunction with a window.

a Figure 2 is a front elevation of the same.

Figure 3 is an enlarged vertical central sectional view of my improved window operating device.

V.Figure y4 is -a front view of the modified form. Y

I here show a mechanical ex ression of my present improvement, whic may be varied in certain respects without departing .from the spirit of the invention so long as it is within the scope of the appended claims.

In the form of the invention here shown, I have a' Suitable cylinder l which is here i shown'mounted on a suitable casing 2 that contains within it a suitable spring 3. The cylinder 1 will be attached yto the casing 2 by spot welding, bolts or otherwise, and the casing provided with a flange portion 4 through whichv screws v5 pass into the win-- dow sill 6. 7 indicates the sash of a window and 8 its glass.

The sprinfr 3 may be elongated'to form a tape 9 whici is provided with a plurality of openings 10 located at suitable points throughout its length. Instead of having the spring itself extended as just described, it will be readily vunderstood that any suitable material may form the tape 9 and have its end attached to'the end of the spring. The upper end of this member 9 ispreferably provided with a loop 11 that ispassed -over a hook 12 carried as here shown on an upwardly extending member 13 that has 1ts lower end 14 suitably attached by screws or otherwise to the window sash'7.

-I here show a diaphragm 14 having its periphery 15 welded or otherwise air tight attached to the inner side of the cylinder. This diaphragm will be made ofy thin metal whereby it can be ressed outward, and the diaphragm prefera ly has its central portion. 16 bulged outward whereby it can be forced or pushed in the-opposite direction. A bolt 17 is slidably mounted in the inner end of the cylinder 1 and its outer end 18v beveled as shown whereby .the tape can freely pass upward by the end of the bolt, and when the bolt passes in one of the openings 10 of the said memberf9, its upper surface end will engage with the upper wall of the opening 10, thereby preventing the said member 9 and thevwindowto which it is at tached frombeing pulled down and the window closed.

I here show any suitable form of coil spring 19 that will serve to engage a suitable pin or projection 20 extending from the bolt v17, whereby the bolt is normally spring'held wl'r'ereby after being pushed outward suiiicientlyfito. actuate'the bolt',vv it will normally spring inward.

. lFor the purpose of charginglthe .cylinder 1 `attached to the'cylinder is a. suitable pipe or lother connection 26 carrying at its outer end a nipple-27, the -said nipple provided with a screw threaded needle valve 28. At the outer end of the stem 29 of this valve is a disk handle 30 that has on its periphery any desired number of numerals 31 that can be made to register with a pointer 32. The object of this handle 30 thus marked will be presently described.

For the purpose of holding the member 9 in proper relation with the extended end of the bolt 17, I provide a member 33 that has its end 34 suitably attached to the inner end of the cylinder 1. Guiding pins 35 also project from the outer end of the cylinder and are located at each side of the tape or other device 9 for suitably guiding it in its movements.

In the form here shown I preferably close the inner ends of the cylinder by a member 36, which carries a central opening that receives the bolt 17, the said member 36 provided also with an inwardly projecting portion 37 through which the bolt passes, thus making a bearing therefor.

The pump 21 is an ordinary air pump pro` vided with a handle 38 for forcing the air through the pipe 22 to the cylinder 1 thereby furnishing the cylinder wlth air pressure. This pump 21 is provided with the usual air valve or valves (not shown) as they are well understood.

Instead of having the end of the spring act as the member 9, the said casing, 2 may be extended laterally as shown in Figure 4. This lateral extension will have the spring 3 attached to a suitable shaft 39 while its end is attached to the casing by a pin or' other device 5. In this instance a spool or other like device 40 may be carried by the shaft and the inner end of the member 9 attached to the spool. It will be understood of course that when the member is drawn outward, the spring will be wound up, and hat the spring always is under tension pulling down on the member 9.

It is unnecessary to specifically describe the manner of 'holding the spring shaft against rotation, but it will be stated that its end or ends 41 are squared and fit in square openings either in the walls of the box or other member, and that the inner end of the spring 42 is att-ached to the shaft. Suit- 3 lable provision is made whereby the shaft can be rotated for putting the spring under the desired tension for pulling the window down.

The operation of the device is as follows: The pumphandle 38 4is operated until the cylinder '1 is filled with air under considerable pressure. This air pressure will force the center 16 of the 'diaphragm 14 and cause it to push the bolt 17 into the position shown in Figures' 1 and 3. The cylinder can be provided with any desired air pressure and the valve 28 closed during that operation. When the window 7 israised the desired height, the end 18 of the bolt will engage an opening 10, thus holding the window in the adjusted position. In order to cause the window to automatically close say at 7 oclock a. m., the handle 30 will be turned until 7 is at the pointer 32. This will permit enough air gradually to escape so that the window will be closed at that time, likewise as to the other figures on the lhandle 30.

Therefore on retiring it is only necessary to charge the cylinder 1, turning the handle 30 to the number indicating the hour that it is desired the window should close in order to operate automatically, whereby the room will be warm when the occupant arises.

Instead of having the numbers on the handle 30 indicate the hour that it is desired the window should close, it may indicate the number of hours that it will require the air to escape and release the bolt 18. When a person retires at a given time, then the numbers may be used to indicate the hour that the window will close. When, however, the occupant is irregular in retiring, then the numbers will indicate the amount of hours required for the pressure to properly belowered to withdraw the bolt 18. By that is meant that a person retiring at 11 p. m. who is desirous of having the window closed at 7 a. 1n. should set the device at 8 which would mean that 8 hours are required for the pressure to release the bolt 18 and the window to close.

It will ot course be understood that the threads on the stem 29 of the valve 28 will be very fine since the adjustment of the air valve must be delicate in order to prevent the too rapid escape of air and at the same time enable the valve stem to be turned to have the numbers on the wheel at the pointer 32. It will also be understood that instead of the handle 30 a lever may project inwardly from this wheel and the lever swing past a numbered dial, the operation then being substantially as that described for the wheel. I desire it also to be understood that this device may be used in connection with dampers, radiator valves, etc., to cause them to be opened or closed at specified times, for the purpose of regulating the heat.

Different Jforms of diaphragms may be used in the cylinder, that is to say it may be corrugated to permit its longitudinal movement, Aand this may` be made` in the locking. device operated bythe diaphragm y and` other details may be changed, ally without departing 'from the spirit and scope of the said invention as expressed in ,the 'api pended claims.
