This invention relates to a storm window sash adjuster which contains many new features of design, and consequently offers advantages and improvements not heretofore found in such devices. This invention has for one of its principal objects to provide an adjuster which may easily, quickly, and without the aid of any tools be connected or disconnected from the storm sash. Thi we have accomplished in a new and unusual manner.

Other objects are to provide an adjuster which will also serve to lock the storm sash securely in a closed position, and to provide means whereby the adjuster will remain in any desired position.

Further objects such as simplicity, strength, durability, low cost, etc., will appear from the following description and drawings wherein Figure 1 is a perspective view of our sash adjuster in a partially opened position, shown attached to a window frame and storm sash;

Fig. 2 is a side elevation of the adjuster in the position which is reached just prior to its disconnection from the sash;

Fig. 8 is a side elevation of the sash adjuster in a modified form wherein the link arm connected to the sash is formed of round stock such as heavy Wire; and

Fig. 9 is a top plan view of the adjuster shown in Fig. 8.

Our new and improved window sash adjuster is in the form of a link comprising arms A and B made of metal or other suitable material. Arm A is formed with a long side wall I5, a short side wall I6 parallel with and opposed to the wall I5 and a connecting bottom I! which terminates short of the ends of the wall I6. A channel that normally faces upwardly is thereby provided. The long side wall I5 is offset at I8 as shown in Fig. 4. Arm B may be made of flat stock as Shown in Fig. 4, or of round heavy wire stock as shown in Figs. 8 and 9. This arm is formed with an elongated hook I9 at its outer end and a stake 2 Claims. (Cl. 292-263) 20 outstanding from the arm about opposite the hook and forming a shoulder.

Arms A and B are pivotally joined as by means of a nut and bolt 2|. In this assembly the arm B is sandwiched in between the walls l5 and I6 of the arm A and is separated therefrom by friction washers 22 (see Fig. 2) which are positioned wholly to the inside of the walls I5 and I6.

When .inuse the inner offset end of arm A is pivotally secured to the frame 23 of a window as by means of a screw or bolt 24, and the outer end of arm B is secured to the sash 25 of the storm window by inserting the hook I9 into an A eye fitting 26 of the ordinary common type which 15 may be attached in the usual manner to the storm-sash. This is done by merely swinging the pivotally joined ends of the two arms A and B'upwardly to a near top position, as shown in Fig. 2, and then feeding the hook into the eye. This is possible due to the absence of any bottom or stop on arm A in the region of the pivot bolt ZI which allows the arm B to be swung through more than 270 until it fetches up against up against the bottom Ii. By reversely swinging the arms to the straight-line position (see Fig. 3) or further, the hook I9 is secured in the eye 26 and cannot be removed. To disconnect the hook I9 from the eye 25 it is merely necessary to swing the arms upwardly to a point well above the straight-line position (see Fig. 2) whereupon the link may be manipulated to effect the desired release.

To adjust the storm sash inwardly the arms are swung downwardly as shown in Fig. 5, and when fully closed the arms will be in the position shown in Fig. 6. The stake 20 prevents the hook I9 from riding up into the eye 26 when the links A and B are in a swung-down position (see Figs. 5 and 6) When the storm sash is fully closed, as in Fig. 6, it may be positively locked in such position by rotating the closed arms A and B upwardly 180 (see Fig. 7) from the normal closed position of the link shown in Fig. 6. The arm B is then prevented from opening outwardly by the bottom I! of the arm A against which it rests. To release the arms from this locked position it is necessary merely to rotate the arms downwardly away from the storm sash to the position shown in Fig. 6.

The friction washers 22 when compressed by properly adjusting the bolt 2| serve to adequately hold the link in any desired position, thus providing the widest possible range of adjustment of the storm sash inwardly and outwardly.
