C. N. CARLSON STORM SASH FASTENER Filed March 1 1929 Patented Aug. 19, 1930 UNITED i stares CHARLES N. CARLSON, F VIRGINIA, MINNESOTA, ASSIGNOR OF FIFTY PER CENT TO PATENT, ()JFFICE CHARLES A. JOHNSON, 0F VIRGINIA, MINNESOTA' STORM-SASI-I Application filed March 1,

This invention relates to storm sash fasteners and has special reference to a novel form of fastener in which means is provided whereby the window may be slightly raised or lowered without alfectingthe storm sash.

The principal object of my present inven-v tion is to provide practical and eflicient means for accomplishing such relative movement of the window sash and storm sash.

Another ob eot is to provide a form of fastener which when supporting a storm sash in open position has the least susceptibility to rattling or abnormal movement.

Another object is to provide a fastener which "may be quickly and easily detached from the window either for removing the storm sash or supporting same in open position independently of the window.

Other objects and advantages of the invention will appear in the following description thereof.

Referring now'to the accompanying drawing, forming part of this application, and wherein like reference characters indicate like parts:

Figure 1 is a perspective view of a fragmental portion of a storm sash and window pairs or of like construction, in which latter event, of course, one would appear-as shown in Figure 1, while the other would appear as shown in Figure 2.

1 represents a portion of the side of a window frame, the outermost stop being illustrated at 2, and the parting strip at 3, while in Figure 1 the lower sash of the window is illustrated in dotted lines at 4 and in Figure 2 is shown in full lines, as the latter View is FASTENER 1929. Serial No. 343,717.

is pivotally connected as at 7 to the clip 8 fixed to the storm sash and upon its opposite end is enlarged somewhat in depth, in the upper portion of whichenlargement is fixed the laterally projecting pivot indicated at 9, which is designed to pivotally and slidably support the innermost end of the arm within the vertically elongated slot 10 in the outwardly extending flange ll of the angle bracket; the opposite flange 12 of which is fastened directly against the outer face of the window sash 4, as by screws or the like engageable through the slots 13 in the flange 12 of the bracket. There is also formed in this flange of the bracket intermediate of the slots 13 an elongated opening 14 by pressing outwardly therefrom the intermediate flangelike member 15, it beingparallel with the flange 11 and properly spaced therefrom to permit of the rounded hub like portion of the end of the bar 6 about thepivot 9 passing readily therebetween in its up and down movement. The lower extremity of the flange 12 of theangle bracket is somewhat pointed in shape and bent outwardly at right angles thereto as at 16, forming a slot 17 between the innermost terminus thereof and the lower corner of the flange 11', thisslot being for the reception ofthe elbow or limiting stop portion 18 of the enlarged end of the bar 6. The end face of this stop portion of the rod or elbow is straight for direct abutment against the inner flat face of the flange 12 at the lower corner thereof, but is provided with an extension or lip 19 at the lowermost corner thereof which overlaps the inner end of the slot 17to'insure a firm anti-rattling grip therein.

Between the stop portion 18 and the pivot 19 is formed an'arcuate slot 20 partially about said pivot andcon'centric therewith for oooperative engagement with the pin 21 fixed within the lower outer extremity of the flange 11 of the angle bracket; this engagement however only' occurring after a predetermined outward movement of the storm sash, and

the object of which is to provide positively against any movement of the storm sash by Wind or the like after being slightly open. It will be seen that when the two sashes are closed the bar 6 will lie in vertical position tightly within the'corncr of the angle bracket and intermediate of the flanges 10 and 15, at which time the pin 21 will be wholly out of engagement with the slot 20, or just at the entrance to same, and in which position the angle bracket is free to move vertically without being affected by the slot. Just as soon as for example the window sash is raised suffiiently to but slightly open the storm sash, the pin 21 will enter the slot 20 showing that it will be impossible to raise or lower either sash without affecting the other, thus providim a positive anti-rattling element in the device, which not only functions as such when the windows are in any open relation, but also assists as such when in their extreme open relation.

It will be noted that the lower end of the flange 15 terminates obliquely as at 22, this being for the purpose of pro 'iding lateral adjustment of the inner end of the rod 6 so that it may be readily removed when desired, but only, at this particular poin that is when the lower extremity of the portion 18 is free from the slot 1?. For as 'stance in the convenience of such adjustment in the event of the fastening device being installed as it were facing the window frame as shown in Figure 1 of the drawings, there is provided the notch 23 for indicating such removable position, and at which time it occurs directly opposite the outermost edge of the flange 11 of the angle bracket.

By this construction it is evident that provision is made for the quick and convenient adjustment of the device either for installation or removal of the storm window, and it is considered that such provision will in no wise jeopardize the efficiency of the device although to provide against any possibility of the lower end of the rod 6 being jarred out of position at this particular point of disconnection, there is provided the catch memher 2% pivotally mounted as at 25 upon the flange 15, and which is designed to overlap the lower end of said flange when in its lowermost position and provide a positive stop against lateral movement of the pivoted termini of the rod, which, of course, will have to be swung up into the position shown in Figure 2 of the drawings before the lower end of the rod can be removed laterally.

It is to be understood that various modifications of tae embodiment here illustrated and within the scope of the appended claims may be resorted to without departing from the spirit of the invention.

Having thus described my invention, what I claim and desire to secure by Leters Patent, is:

1. The combination with a window and storm sash therefor, of a fastener connecting same comprising a rod pivotally attached at one end to the storm sash, means at the opposite end for pivotally connecting it to the window sash, said means comprising an angle bracket having a vertical slot in one flange thereof forming the pivotal connec tion with the rod, and means whereby the rod is separable from the bracket only'whenat a predetermined angle to said bracket.

2. The combination with a sash fastener of the class described having one adjustable end, of an angle bracket for cooperative engagement with said end, and means whereby the fastener and bracket are unitable or separable only when at a predetermined angle to each other.

3. The combination with a sash fastener of the class described having one adjustable end, of an angle bracket for cooperative engagement with said end for permitting vertical mo ement of the bracket without movement of the fastener, and means preventing such movement when the fastener is at an angle to the bracket.

4. The combination with a sash fastener of the class described having one adjustable end, of an angle bracket for cooperative engagement with said end for permitting vertical movement of the bracket without the fastener only when they are lying substantially parallel with each other.

. In testimony whereof I a: X my signature.

CHAR-LES N. CARLSON.
