Patented Dec. 19, 1944 UNITED STATES PATENT OFFICE 2,365,323 STORM SASH vEN'rnA'roa Martin H. AveLallemant, Milwaukee, Wis. Application December 10, 1941, Serial No. 422,423

6 Claims.

The present invention relates generally to improvements in the art of ventilation, and relates more specifically to improvements in the construction and' operation of ventilating devices especially adapted for-cooperation with storm sash or other building closures.

An object of the-invention is to provide an im proved ventilator which is simple in construction and efficient in operation.

' It has long been customary in the building industry, to provide ventilators associated with storm sash or the like, for permitting a moderate degree of fresh air ventilation without necessarily opening the storm windows to which the ventilators were applied. These prior storm sash ven-' tilators usually consisted of a series of holes bored through the'lower rail of each sash, and a closure plate for the holes pivotally attached to the inner side of the rail laterally beyond one end of the series, the plate being swingably adjustable from a position wherein all of the holes were completely closed, to various positions wherein the holes were moreor less uncovered. Since the elongated closure plate of this prior type of regulator was pivotally suspended from endonly, usually the right hand end, adjustment of the plate would always 1 necessitate opening of the opposite or left hand ventilator, it was heretofore necessary to remove the closure plate by unscrewing the pivot; and these prior devices also required the use of considerable'unnecessary stock in the formation of the closure plate and the stop plate for limiting the closing-movement thereof.

The present inventi'ontherefore contemplates provision of a new and useful storm sash ventilator which obviates all of the above ,mentioned objectionable'features of the prior swing plate ventilators, and which can be readily applied and actuated to produce any desired degreeof ventilation or distribution of the fresh air.

Another specific object of my invention is to provide an improved window ventilator of the type having one or more slotS or openings adapted to be closed by means of'an adjustable plate,

J mi w e n Fe 1? a m y b e are readily and quickly detachable or removable in order to facilitate cleaning or painting of the window frame or. other parts.

An additional specific object of my presentinvention is to provide an improved ventilator assembly which can be manufactured and sold at moderate cost and without th use of excess material, whichcan be readily-installed and manipu-' lated, and which is highly attractive inappearance. v

These andother objects and advantages of the improvement will be apparent from the following detaileddescription.

I A clear conception of one simple embodiment of the invention, and of the mode of constructing, of applying and of manipulating the improved ventilators, may be had by referring to the drawing accompanying-and forming a part of this specification wherein like reference characters designate the same or similar parts in the various but showing the regulating plate adjusted to partially open some of the vent holes;.

Fig. 3. is another similar elevation of the yentilating assembly, but showing the adjustable control plate positioned to uncover. all of thevent holes; r

Fig. 4 is still another similar view of the ventilating'device, showing one of the end retainers released to permit free swingingor removal of closure plate;

Fig. 5 is a transverse vertical section through the window and ventilator assemblage, taken along the line 55 of Fig. 1; and

Fig. 6 is an enlarged fragmentary section through the ventilator and window rail, taken along the line 6-6 of Fig. 1.

5 5 While the invention has beenshown and devided with a horizontal slot or a series of boredv holes 8, and being associated with atransparent window pane 9; and the improved ventilator assembly comprises in general an elongated closure.

plate ID of sufficient length and'breadth to completely cover all of the holes 8, and a pairof oppositely disposed pivotally suspendedspring arms II secured to the rail 1 by pivot screws l2 and having inwardly directed swinging end projections i3 cooperating with-sockets hi formed in the ends ofthe platel'il.

Asshown irrthe. drawing, the closureplate l .may be formed of sheetmetal with the aid of punches and .dies,.and when so formed, it=is preferable. to .disnthis plate. 1 0. sumcientlyto provide an elevated grippingridge lfi-along the edge thereof so as to facilitate adjustment. This plate. illv may. however beformed of non-metallic material, and in ordergtoieliminate-waste of stock,

the closure plate may obviously bereduced in size. on area so. ,that..it will .just cover the vent slots or holes 8 when'the plate is in closed position, see Fig. 6. Theclosureplate ill of theven tilating assemblage may also be attractively decorated,,and the sockets. l lzmay be circular and preferably do not penetrate the plate Ill. The surface or outer edge portionoi the plate flange cent plane surface of the vwindowrail 1 when the plate is in closed position; and the opposite ends of the elongatedplate-may be either semieircular. as shown, or any other desirable shape, but the plate lil is preferably-of symmetrical contour so that it cannot be improperly assembled.

The plate suspension arms which-are pivcta'lly attached to the lower window rail I be holes 8 by the pivot screws l2, are preferably formed of spring metal', and have their swinging ends. biased towardthe adjacent surface of the rail 1 so that the integral and projections l3 will be retained within the sockets I 4 and the entire; plate lil will be constantlyresiliently urged toward the mill. The arms ill are preferably of like and, interchangeable construction and may beformedwith the aid of punches and dies,;and

the pivot scnews 12 should 'be so located that they will permit theplate i0 to-be positioned either over :the holes- 8 as in- Fig. l, or entirely freefrom the .ventholes 8- as in Fig. 3, or in any intervening tilted position either inclined to the left or to the rightas in Fig. 2, The suspensionarms ll .while normally maintaining the ventilator assembled, should be-sufficiently flexible so that either or both of them may bereadily withdrawn fromthe plate sockets l4 as shown at the right of Fig. fl, thereby permitting theclosure plate l0 to beeither swung away from the rail 1, or entirely removed from the-window in order to facilitate cleaning or painting. The integral end projections I3 0? the suspensi'on arms ll rather loosely. coact with the-sockets l4 order 16 should be formed t0...snugly engage .the

' yond the opposite ends of the series of vent,

to avoid binding of the parts, and the pivot screws l2 may be ordinary wood screws.

During normal use of the improved ventilator, after the suspension arms ll have been properly applied to the sash rail 1 with the aid of the pivot screws l2 and have been caused to properly cooperate with the sockets M of the closure plate I0, this plate may be conveniently adjusted to various positions by merely grasping the plate ridge l5. When the ventilator isnot in use, the closure plate l0 will be positionedias shown in Figs. 1, 5 and 6, and will thus seal the vent holes 8 in the rail 1. If a moderate degree of ventilation is desired, either end of the closure plate sill-may. .be swung upwardly to partially uncover the adjacent vent holes 8 as depicted in Fig. 2; and if maximum ventilation is to be effected, the. oppositeendsof .the elongated plate It] may beelevated in succession so as to place the plate in its highest position as illustrated in Fig. 3 wherein theholes 8 are entirelyuncovered., The closure plate illmaythus-be readily adjusted to uncover the ventholes8 :to any; desiredqextent, or. ,to; uncover only selected-end -holes,-..and-.-the swing links cramps ll will nevenpermit the plate It) to moveabpve the topipi thelower rail a yrhiehe th nssshown infield. The sp i ll normally pressthe-closure-plateHLsnugly against the sash raill while permitting convenient sliding of the plate ior, adjustment purposes; but if it becomesdesirable to partially or completely release the closure plate Ill, the swing links or arms ll mayv bewithdrawn from ,the sockets id as shown .in,'Fi g'.,4, thereby permitting free access to the surfaces. normallyconcealed by the plate l0.

From the foregoing detaileddescription it will be ,apparent that present invention. provides an improved ventilator especially applicable to storm sash or the like, ,which is simple, compact, and durable in construction, and which is moreover. highly effective and flexible in use. 'By forming the closure-.-.plate l0 symmetrical .as shown, and the suspension arms ,l l --interchang-e ably similar, the .cost' ofv construction is not only reduced to a minimum, but possibility. oferror in making installations is also-minimized and the improved assembly can obviously be applied as a unit to practically any standard storm window having either a single elongated vent slotor a series of holes8 such as shown. The improved ventilator can. also be. produced with practically no waste of ,materiaLandjis operable without ,undesirably obstructing theviewnthrough the window; and the. closureplate .lll may be-quickly and conveniently removed from the suspensionarms II in order to gainaccess to the. normally concealed surfaces. The device is readily manipulable by virtue of the previsiono -the; shoulder ridge l5, and has provenentirely ,satisfactoryin actual use.
