STORM-SASI-I FASTENERi Application filed April 21,

To all to IlOlitiZi may concern Be it known that 1, Armor: Scrmonnnn; a citizen of the United States, residing at St. Paul, in the county of Ramsey and State oi Mi11nesota, have invented certain new and useful Improvements in Storm-Sash Fasteners, of which the following is a specification;

T his invention relates to devices for howing windows such as storm sash and the like, and has for its object to provide in a bowing device improved means for holding the win dow in outwardly extended position, which will not rattle or become easily dislodged.

A further object of the invention is to provide in a device of the class described an antirattling stay bar in connection with a bracket which may be easily manufactured. and which will be neat and ornamental in appearance. To this end the invention consists in the construction and combination hereinafter described and claimed: In the drawings:

Figure 1 is a perspective view of a stay bar and its bracket embodying the invention.

Fig. 2 is a side view of the invention showing the stay bar pivoted to a window sash.

Fig. 3 is a top view of the stay bar and bracket, and

Fig. i is a diagrammatic view showing one position of the parts when locked.

A designates a window sash, B a bracket suitably secured thereto as by means of screws, C a stay bar and B a bracket slidably supporting said stay bar.

The bracket is formed from a plate bent at right angles so as to form a base plate 1 and lugs 2 and8 disposed in spaced relation, the opposite edges of said lugs adjacent the space between them being parallel, the upper edge of the lower lug 3 has extending upwardly therefrom the comparatively high narrow projection or stop 4h having its straight upper edge in parallelism with the edges of the lugs 2 and 3 adjacent said space. The base plate 1 is formed so as to extend beyond said lugs to form the gage block 5, the vertical outer edge 6 thereof serving as a guide whereby to facilitate mounting of the bracket on the window frame (not shown).

The projection or stop 4; on the lug 3 is comparatively high and narrow, its inner edge adjacent the space between the lugs 2 and 3 being for a distance parallel with the face 01":

the base plate 1 to form the side 7, the balance of said edge inclining outwardly away from said base plate to form the edge d. The space between the lugs which is comparatively wide and high is adapted to receive so as to slide longitudinallv therein the stay bar C. The stay bar consists of a strap-like bar oiuniform width, sliding edgewise in said space and connecting with the bracket 13 by means of the pin 9 sh as to swing in a vertical plane thereon. At its upper edge preferably near its outer free end is the notch 10 adapted to loosely receive the lug 2 edgewise, the notch effecting a narrow place on the stay bar. This narrow portion of the stay bar is entered loosely sidewise into the space between the .top of the fingers and the lower edge of the lug 2 when the latter is inserted in the notch 10, so that the bar may be placed within the space and slid longitudinally therein. The space between the finger and the lug 2 may be termed the entrance to the stay bar. At its outer extremity the stay bar is rolled upon itself to form an elongated eye or loop 11. p 1

As indicated in Fig. 3 the face 12 of the stay bar lies flatly against the base plate 1 of the bracket, the outer leg 13 of the loop 11 which is bent against the opposite face of the stay bar being comparatively straight so as to form a wedge adapted to be projected into the space so as to contact with the face of the base plate and the edges 7 or 8 of the finger 4. In its lower edge 14 the stay bar has a transverse notch 15, to form a shoulder with its wall 16 at a position cutting the wedge between the bend of the loop and the vertex of the converging sides thereof so that said notch will be in a position to receive the horizontal edge of the lug 3. When the notch 15 is in full engagement with the lug 3, as shown in Fig. 1, the converging faces of the wedge will be in firm contact with the face of the base plate 1 and the finger l thus obviating any possibility oi rattling thereat due to the vibration of the storm sash. In order to facilitate locking of the wedge in the bracket the finger 4 is slightly beveledas at 8 so that when the stay bar is projected-forwardly with its upper edge contacting with the lower edge of the lug 2 until the wedge is seated with its opposite sides it may then be pressed downwardly until the notch is seated on the lug V -tional pieces to be riveted'to the latter, the

3 as above explained. Thus, is secured a tlght fitting wedge joint between the'bracket and stay bar without resorting to any addi latter being made of a single piece of uniform width preliminarily stamped or blanked with respect to the notch 15. The bar is then rolledupon itself by means of suitable dies so that the slot will come at right angles to the face 12 of the bar.

The bevel portion of the stop his sufficiently long to permit the edge of the lug 3 to partially enter the notch 15 (Fig. 45) so that absolute accuracy in the formation of the wedge is not absolutely essential though preferred. As long as that part of the lower edgeof the wed e 1n the notch is in the zone of the beveled slde 8 the wedge is free to be moved back and forth until the forward wall 16 of the notch 15 contacts with the forward face of the lug 3. The Wedge may then be forced downwardly as far as it will go when it will be firmly gripped and held. When the wedge is perfect it will fit as indicated in Fig. 2. The lug 3 in connection with the so as to receive the lower edge 111g when said wedge is in engagement with respectively said parallel vertical sides, and a notch d1sposed transversely of sand wedge of said openthe parallel vertical sides thereof.

V 2. Ina device of the class described, the combination with a bracket on the window frame having a vertically disposed plate extending edgewise into the window opening said plate having an opening with upwardly and outwardly diverging sides, a stay bar .slidable longitudinally at right angles to said plate in said open ng' and being bent upon itself to form a wedge the sides thereof converging toward the body of the bar, and a transverse shoulder facing away fromthe body of the bar and located in the lower edge thereof intermediate the length of said wedge so as to abut against said plate when said wedge is wedged between said diverging sides.

In a storm sash hanger, of the class described, a stay bar formed with a forwardly directed, wedge at its free end, a shoulder facing opposite to the direction of said wedge, and a bracket formed with oppositely disposed sides adapted to wedgingly receive said wedge between them, a part of said bracket beingso disposed as to become alined with said shoulder when said wedge is wedgingly positioned so that said bar may be moved to bring said shoulder and bracket part into engagement-to hold the bar against longitudinal bracket. p

In testimony whereof I affix my signature.
