Application July 7, 1936, Serial No. 89,398 12 Claims. (01. 268-123) This invention'relates to closure operators,
and its general object is toprovide a device of that character which is primarily designed for automatically closing a window, in the event of '5 rain or excess moisture passing within'the win- I dow opening, thereby preventing damage by storms and moisture laden atmosphere. j
A further object of the invention'is to provide an automatic window closing device that cushions the closing action of the window, thereby preventing damage thereto, as well as to the parts of the device.-
Another object is toprovidean automatic window closing'device that can be attached to either side of the window, as well as enclosed within the sash, so as to be completely hidden from view, when the window is in closed position.
A still further object is to provide an automatic window closing device that can be set; to remain in open position, is easy to install, compact in form, simple in construction, inexpensive to manufacture, and extremelyeflicient in operation, use and service.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter'fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims. 3O 1 In describing the invention in detail, reference will be had to the accompanying drawingswherein like charactersdenote like or corresponding parts throughout the several views, and in which:
Figure 1 is a perspective fragmentary view illustrating one form of the present invention applied to a window.
Figure 2 is a vertical sectional view taken therethrough.
Figure 3 is a fragmentary view illustrating the position of the parts when the window is being closed.
Figure 4 is a sectional View taken approximately on line 44 of Figure 2," looking in the direction of the arrows.
Figure 5 is a detail perspective view of the fragile keeper member used with the present device.
Figured is 'a fragmentary sectional view illustrating a modified form of the present invention applied to a window.
Figure 7 is a fragmentary viewof the device per se-and taken at right angles toFigurefi.
Figure-8 is a sectional view. taken approximately on .line"8--8 of Fig.ure 6,l looking in the direction of the =arrows.. I
Figure 9 is a sectional view taken approximately on'line 9-9 of Figure'8, lookingin the direction of the arrows.
Figure 10- is a sectional view'taken through the cam bearing cap.
Referring to thedrawings in detail, andp'arr ticularly to the form as'showninF'l'gures 1 to! inclusive, the letter A indicates the base of a window frame and B the lower-sash whichto- M,
gether with the base has our device attached thereto, as'clearlyshown in Figure 1.. I
flThe-device includes a cylinder I having a closed upperend'Z which has formed therewith a right angle extension 3, provided with openings to i'receivesecuring means suchas screws, as shown, for fixing the cylinder to the sash -B,'for disposalin depending relation with respect thereto.
The lower end of the cylinder is closed by'a cap 4 which is threaded thereon and provided with an opening "forthe passage of a piston rod 5 therethroug'h, the latter having secured to its pperend a piston 6 of the cup washer type, as shown. Surrounding the rod 5'and having its end convolutions engaging the piston 6 and the cap 4 isa coil spring I, for the purpose of urging the cylinder downwardly on its piston. It
' will'be obvious that as the cylinder is being moved into-rounded seats in the lower en'dsthereo'f for the purpose of receiving the pin ll of a'dog 12 which is pivotally mounted on the cap 4 and spring pressed for normally retaining thepin thereof within one of the notches to; hold the window in openposition, as clearly shown in Figure l. However, the rod'5 is rotatable to move the notcheslll out of the'path of 'the dogl'2, to allowthe window to close by the action of the spring, in this form of the invention. p
The lower end of the rod 5 is mounted'flfor' rotation #within a sleeve l3 that is formed on and rises from a base plate M, the latter hav ing aperturesftherein to receive screwsor the like, to--be '-flxed'tothe base A of the window name, as clearly shown in Figure 1, "and "the sleeve l'3has its open free end closed by a cap l which is fixed to the rod by aset screw or the like. a
Extending from the'sleeve is a bracket l6 5 which has fixed thereto an arm II, the latter extending horizontally therefrom for cooperation with an arm [8, that is threaded orotherwise secured to the rod 5, for horizontal swinging movement withinja slot 19 that extends for a 10 portionjfof its 'ycircuniference of the sleeve; l3; whereby thearm i8-can be disposed parallel with the arm 1'! or at right angles thereto, as
shown in full and dotted lines in Figure 4.
The rod is urged to a position for. disposing;-
the notches l0 outof the path of the dog l2, by
a coil spring that surrounds that portionxof the rod within the sleeve and has one end"fix"ed-r'" to the sleeve and its oppositeend to the rod,
clearly shown in Figures 2 and-1, it being ob employ a fragile keeper s'tr ip2l whichv of course a;acts-in;then capacityas moisture responsive ,meansand as best shown infFigure 5, is preferablyan elongatedlstrib ,of paper having its end portions secured together bysuitable' adhesive .jmeians 22, to provide a band for disposal about,
the free end portions of the arms l1 and i8.
;We likewisevemploy manuallyactuated means r i for, holding the parts against movement; andin the form as shown, the; arm It has slidably' mounted ;thereon a collar 23 which is limited H iniit's movement by a pin, and the inner end of} the collar 23. is provided vwith lugs 25 that arefreceivable inrecesses26 arranged at one end of the slot l9, andin the upper and lower walls thereof, astbest shown in Figure 1,- consequently whenthe Jugs are mounted in the recesses 2B,,itjwill be obvious that :the device is held against mo'vement,,. but when the device is set to beacted upon bymoistureor rainwaterthe I collar 2315 moved to the full line ipositionffof Figure}, and in the eventt'the 1 strip or band 2| becomes broken the spring-2|] will rotate, the re 1" d eeelns t net he ea the path of the dog. -,l 2,, and therebyresult in the ndow'being: closed by the action of j the coil 's'pring;1.

The sleeve 35 is provided with lugs 39 rising therefrom and diametrically opposed with respect to each other to be received in like also has a cam lug 40 formed on and depending from the inner surface there of,:as best shown in Figure 10.
i Extending through thef'rodifll isja' pin'4l, and' the rod is held agai'nsvmovement by the cam lug 40 being disposed in the path of one ofthe projecting 'portionsof the pin 4|, it being "obvious thatthe cap must be raised for disposing the lug40 out of said path, to allow the rod f -to2be 'rotated, and" the rodis rotated by a coil pring 42 in the. same manner, as described in the form shown in Figures 1 to 4 inclusive."
