Application February 19, 1952, Serial No. 272,450

2 Claims.

This invention appertains to storm window construction and more particularly to new and novel storm window latches.

Heretofore, removable storm windows, particularly the type that are pivotally hung to the top portion of the window frame, are provided with various latching devices which, when locked, firmly secure and hold the storm sash in place. If it is desired to open the storm sash for ventilating and airing the interior of the building, etc. it is necessary, in these prior devices, to unlock the storm window latches in order that the stor'm sash be free to pivot upon its outside hangers. If the storm sash is of a fixed type where the latching device is unlocked only for the removal of the storm sash, the lower transverse frame member or bottom rail of the storm window may be provided with an opening usually coveredL by some type of pivoted cover which may be swung away from the openings when it is desired to air the room. There has long been a need therefore for a latching device for storm windows which will firmly secure and lock the storm sash in its closed position but which will automatically open or pivot the storm sash on its hangers when the window sash is raised.

A primary object of my invention, therefore, is to provide a storm window latch which will firmly lock the storm sash in its closed position but which will automatically open the storm sash when the lower window sash is raised.

Another object of my invention is to provide a storm window latch which will automatically open and close the storm sash upon the raising or lowering of the window sash.

A further object of my invention is to provide my storm window latch with means which will allow the window sash to raise independently of the storm sash when the storm sash is stuck or frozen shut so that an instrument may be utilized from inside the roomto force the storm sash open.

Another important object of my invention is to provide a storm window latch having a latch bar pivoted at one end to a bracket secured to the storm sash but slidably and pivotally secured to a bracket fastened to the lower window sash.

A more specific object of my invention is to pvotably mount the inner end of the latch bar to a headed pivot bolt which is in turn resiliently secured to the window sash frame, the pivot bolt being under suicient tension to normally pivot about the upper end of a slotted bracket secured to the window sash frame but when the storm sash is stuck or frozen shut the pivot bolt will 2 slide down in the bracket slot to allow the lower window sash to be raised independently of the storm sash.

A still further object of my invention is to provide a simple, practical and reliable construction that is economical to manufacture, easy to assemble and positive in its operation.

With the above and other objects in View, which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

One preferred and practical embodiment of the invention is shown in the accompanying drawings in which:

Figure l is a vertical transverse section through a conventional window and storm window construction and illustrating in side elevation one of my novel storm window latches afxed thereto. The full lines indicating my window sash and storm sash in the closed position and the dotted lines represent the lower window sash and storm sash in their open positions;

Figure 2 is an enlarged fragmentary side elevational View of my storm window latch shown in Figure 1 of the drawings and again illustrating the two positions of the window sashflatch and storm sash;

Figure 3 is a fragmentary side elevational view of my latch similar to Figure 2 of the drawings but showing the lower window sash in the raised position and the position of the latch and storm sash when the storm sash is stuck or frozen shut; and

Figure 4 is an enlarged fragmentary rear elevational view of my latch looking in the direction of the arrows on the line 4 4 of Figure 2, certain parts being in sections to illustrate further details of construction.

Referring now to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter L generally indicates one type of my improved storm window latch and the same is shown secured to a conventional window and storm window construction.

While the window and. storm window construction forms no part of my present invention and may be of any standard construction, for the purpose of illustration I have shown one window frame, a pair of double-hung regular sash, and a storm sash. The window frame includes the sill I0, side pieces l l, top piece or jam l2, and the stool I3. Let into the side pieces and jam area pair of parting strips I4, whose inner side edges form a guide for the upper window sash I5.

I also provide an inner stop bead I6 which forms in conjunction with the inner parting strip I4, a guide or runway for the lower window sash I1. The window sashes I and I1 are provided with the usual glass G which are held in position by putty I8. The storm window W is also of the conventional type and the frame is of a one piece construction V'having an intermediate Ytransverse strip I9, separating the upper and lower glass members G'. to the outside wall of the building by means of any standard type of hook and eye hanger-H.

In utilizing my novel storm latch I provide a pair of identical latch members L', veach secured.

to the respective stile on each sideof .the .lower window sash I1 and storm sash W. However, for purposes of illustration, I have shown only one stile or end of the window and storm sash construction with one of my .storm latches kL 'applied thereto.` The "storm, window latch lL includes broadly, an angle bracket which is fastened Vto the inner surface of the upright side frame member lor-stile-2fl `of the :stormsash, a bracket 41-212 which is :secured to ithe outer surface of the Vupright side frame member .orstile .'35 of thelower windowfsash ;I1,-.and -pivotally ysecuredvto each of the;brackets2|l:and;22 is the respective Yend of the latch rod or lever 23.

:Referring :howto-Figure 4 lof the drawings, -it is readily apparent that '.the vangle bracket Y2 0 vis vfas-,- tened to the storm sash-stile 2! by ymeans-of the screws f'Sfand the yupstanding angle section ,-24 vof the-bracketis providedjwith :a transversely Vexf7' tending pivot pin which extends through the aperture z,2li ormedin-the section 211. The pivot pinv'l 5 lis providedfwith'ahead :21 l and a spaced integral washerZB `and thus the longitudinalmovement-of the Apivotfpin 25 is prevented.'v While it is notnecessary, the outer1end of the: pivot pin 25 is 'tapered at :'29, the purpose Yoi which will :be readily :apparent as the description proceeds. The angled bracket 22 `isfastened-togthestile 33 of fthe lower Vsash :I-I by means-of -thescrews .-S.

YBracket 2-2 -is-also provided 'withwan vupstanding angleisection f3 I and 'this fbracketeis Vof considerably. greater :length than bracket 20.` The ripstanding section 3| of the bracket 22 is-provided with zan elongated :slotr'32 which -is :adapted to receive a '.h'eaded bolt'33.A The headed bolt 33 passes through'an aperture formed'ononeend-of thexlatchrrod'f23 andtis received 'intheslot 32 of section :of the bracket.l Theouter shankend 34 of the head bolt 33 is threaded for the reception Iof :.a flock :nut- 35. Received Tover `iahe fshank end :34 of fthefbolt-33 `andfbearing Yagainst .the innerzsurface'of section 3f! 'of bracket ,f2'2'oncthefside opposite fromthe -latch rod .23 isfa washer 36 upon which one end of an expansionspring3'I -is adapted :to rest, the other -end of the'fspring 31 rests againstthe lock washerfBwwhich :is-also received-onltheshank13A-.of bolt 33` and Lwhich bears lagainst the lock nut 35. ,By ,threading the lock'nut 35 -.on vthe shank-end34 of the bolt ,the tension vof :springl .maybe adjusted. .Fornormal use of my latch the latchrod.23.is pivotedto bracket 22.at.one end by means of theheadedbolt 33 .and the otherend is provided with an opening `.39 which 4receives the shankend29 of the pivot .pin V25 in the position illustrated bythe full .lines The storm sash is pivotally hung l tured end 39 will move off of the pivot pin 25 and the lever 23 may be moved to a vertical position parallel to the stile 30 of the window sash I1 and the storm sash may then be removed from the hangers I-I.

However, in utilizing my novel storm latch mechanism it will be assumed that the latching lever 23 is in the full line positions illustrated in Figures 1, 2, 3, and 4 of the drawings. Lock nut 35 is threaded on to the headed bolt 33 so that thev spring 31 Iis under considerable tension, whereby, when the window sash I1 is raised in the direction of the arrow to the dotted line positions illustrated in Figures 1 and 2 of the drawings, headed bolt 33 will, in eiect, form a rigid pivot point .in -a .manner similar to the pivot pin 25 and the storm sash will be swung out in the direction of the arrow to the dotted line position shown in thedrawing and my novel storm window latch L will assume the dotted line position as shown. It is .readily .apparent therefore, vvthat .by .raisingland lowering the .window .sash I'I .my vstorm ,sash `W will, under normal circumstances, be .correspond-v inglyopened or closed..

4Insome instances, however, the stormsash W may become stuck o1' frozen .shut and .therefore the .raising ofthe sash would not create suicient leverage `to .break the storm ,sash loose. In this instance it is to be `noted that the ,tensiornoiv spring 3,1, while. being sufficient to allow V. a 1miform Vopening and closing of Vthe -window sash land .storm window sash, will now yield and .the headedbclt 33 will slide ,down `in the slot 3,2 .when the window is moved inthe direction ,of Athearrow in Figure 3 of the drawing. This `willallow enough space under vthe sash to insert a toolbar or the likefor loosening `the storm,sas'h. `Vllhen the stormsash is loosened the headedbolt 33 ,isl returned to ,its upper position in slot 32 ,and 'the storm sash will again respond to the ,automatic raising and lowering of the sash I1.

,Again lit isto berunderstoodthat in 'the preferred embodimentoi `the invention, I providev each end of Vmy window and storm windowcon-l struction withmy novel storm latch device L: However, one vof the latch devices may suflice b ut whereverpossible I utilize one on each side.

From ,theforegoingit is believed that the-fea-v tures and advantages of the invention will be readily apparent to those skilled in the art, land it will, of course, be understood that changes in theV form, yproportion and minor details ,of vconstruction ,may be .resorted towithout `departing from the spiritbf the ,inventionbr the-scope ,of impending claims.
