This-inventionrelates to" closure'fast'eners' and more particularly" those for securingstorm' sash in position at the exterior of window casings; Since=I anticipatea-major field of use of the device to be in connection with such storm sash, I shall herein describe such application as the specificterms in such description will easily be comprehended as used in an exemplary sense. As the description proceeds, it will be clear that I provide aconstructiorrembodying parts adapted i 2' Claims. (01. 292-303) for permanent installation on the storm sash. and l the window casing which will not interfere with the movements of the'sashes of the window proper andwhich permit the storm sash :to be secured from the interior of the building and firmly pressed in against the exterior of the window casing.

It is customary to provide storm windows" in the form of a single glazed sash which rests on the sill of a double hung window and overlaps the sides and top of the exterior casing. The commonest method of mounting them is by the use of wood screws driven into the outer face of the casing. This breaks the surface of the casing and the screw holes soon wear large. Moreover, it is laborious and dangerous to scale the building exterior in order to secure the sash. A device embodying permanently mounted parts on the sash and on the casing manipulable from the interior of the building is therefore desirable and such devices have been proposed and to a certain extent used. The fastener should be rugged, yet if the upper sash of the window is to be left clear for operation it must be housed in the narrow zone (about /8 of an inch in depth) between the outer face of the casing and the trackway of the upper sash. It should be capable of manipulation by simple movements not involving nice adjustments and provide for a considerable range of movement in the storm sash itself, permitting the latter to be drawn inwardly tightly against the casing. In accordance with my invention, these requirements may be met by a simple and inexpensive construction of which an illustrative example is shown in the accompanying drawing, wherein:

Fig. 1 is a horizontal section through one side of a double hung window showing a portion of the upper sash and the adjacent casing and the overlying stile of the storm sash secured over the window opening by a, fastening exemplifying the invention;

Figs. 2 and 3 are sections on the lines '2-2 and 33 of Fig. 1 respectively; and

Fig. 4 is a perspective view of the fastener.

Referring to the drawing, I there illustrate a portion ortheupper sash it of a double hung window;- which sash slides between the parting strip. i2 and the. vertical element id of the casing together with: one i offthe vertical. stiles of; a, storm sash l6 overlying that casing and securedby a fastener illustrative" of the invention; this: being. received'in the angle defined bytthe inner edge of the casingJM and: the interiorface-of the storm sash? l6- and located exteriorlyl of the path of the upper .w-indow sash. It: Usually two or three fastening. elements-Willi be installed at either side of thewin'dow opening althoughiat the bottom they maybe located along the sill and at: the'top insthe angle formed by the horizontal member of. the "casing,

In the case of allstorm'lwihdow" securedrirom the inside as shown and embodying a fastener located in :the 'interiorly. facing. angle referred to, the element mounted on the built-in window structure may be a simple headed pin lil, conl veniently a sturdy round-headed screw as shown,

driven into the edge of the casing about half-way between its sides and projecting perhaps of an inch. The storm sash is latched thereto by a latch proper connected to the storm sash and engaging the interior side of the screw shank inwardly of its head.

The element mounted on the window sash comprises a base conveniently in the form of a short length of structural angle, one flange 22] of which is provided with suitable screw holes 2| to receive screws by means of which it may be secured to the inner face of the stile of the storm sash so that when the latter is in position the other flange 22 will pass the inner edges of the casing M in a plane intersecting the exposed neck of screw 18. The flange is provided with a slot 24 to receive the screw. A latch proper is provided in the form of a swinging arm 26 which herein takes the form of a length of heavy, somewhat resilient wire, one end of which is coiled around and pivotally connected to a pin 28 at one side of the slot 24 so that the arm may be swung from an open position as shown in Fig. 4 to a position crossing the slot 24 to engage the shank of screw 58 at its inner side and inwardly of its head. By virtue of the yielding character of the arm 26 and its somewhat loose connection to the pin 28 the lower end of the arm may be forced past a headed pin 30 at the opposite side of slot 24 and brought to rest behind the head of the same, as shown in Figs. 2 and 3, thus locking the sash in position.

The lower end of the arm 26 extends downwardly and may be coiled to provide a finger-engaging portion or handle 32.

The arm in the unlatched position provides a substantial and convenient handle by which the storm sash may be manipulated and brought into its final position. The parts are preferably so proportioned that a considerable leverage is provided so that an adequate tension may be placed upon the arm, drawing the storm sash downward- 1y, viewing Fig. 1, to its seat on the outer surface of the casing to make a tight joint, the arm in its engaged position preferably being, when the parts are locked, somewhat flexed in resiliently tensioned position as illustrated in Fig. 2. It will be noted that in locking the parts and applying this tension to the storm sash the strains are always inward, there being no tendency to displace the storm sash once it has been positioned in the window opening. In fact the engagement of the walls of notch 24 with screw 28 provides a support for the sash against vertical displacement.

The use of a wire as shown is desirable not only on account of its cheapness and simplicity but because it can easily be bent to provide a desired degree of tension to suit the conditions of a particular installation.

I am aware that the invention may be embodied in other specific forms Without departing from the spirit of essential attributes thereof, and I therefore desire the present'embodiment to be considered in all respects as illustrative and not Number particular embodiment described and which I desire to secure by Letters Patent.

I claim: 1. A fastener for storm sash or the like com- 4 prising a base having provision for securing it to the face of the sash and including a plate projecting therefrom to lie along the inner edge of the window casing, the plate having an opensided notch to receive a pin projecting from the casing, a yieldable arm pivoted at one end of the plate to swing transversely to the casing and means on the plate for releasably engaging the arm adjacent its other end with its middle portion across the notch to engage such a pin received in the same.

2. A fastener for storm sash or the like comprising an angle iron having screw holes in one flange and a notch extending inwardly from the edge of the other flange, pins projecting inwardly from said other flange at either side of the notch, a resiliently yieldable wire terminally journalled on onepin and adapted to be releasably latched REFERENCES CITED The following references are of record in the file of this patent: i v UNITED STATES PATENTS Name Date Martin Oct. 18, 1892 Poertner et' al.
