Application filed June 7, 1926. Serial No. 114,240.

This invention relates to a combined sash holder and window release of the charactershown and described in my Letters Patent No. 1,547,775, issued July 28, 1925.

In this patented construction a stationary lever extended from the side of the sash holder casing at the. top, while a pivoted lever projected from the casing below the- Figure 1 is an'inside elevation showin an ordinary sash holder equippedwith one oi'm of my improvement with the parts in normal position- Figure 2 is a view similar to Figure 1 but showing the pivoted lever operated to release the sash Figure 3 is a view similar to Figure 1 but showing a modified form of the invention- Figure 4 is an elevation similar to Figure 3 but showing the position of parts after the pivoted lever has been operated to release the window Figure 5 is .a view similar toFigure 1 but showing the stationary lever extending from the bottom portion of the casing instead of from the top, and

Figure 6 is a view similar to Figure 5 but showing the positions assumed by the parts after the pivoted lever has been operated to release the window.

In the description to follow similar numerals of reference will be used to desi ate similar parts in the several figures o the drawing. f

Referring to Figures 1 and 2, 1 denotes the casing of the sash holder provided with the usual dowels 2 to extend within the sash. 3 is an L-shaped sash holder lever, hereinafter called the operating member, pivoted to a post 4 extending from the casing, and 5 is a coil spring interposed between the inner from the upper ed e of the inner end 6 of the operating mem er 3.

In Figure 1 this bolt is shown pro'ected for latching engagement with the usual rack at the side of the window casing, and the spring 5 acts against the operating member to normally effect this and to swing the outer lever 10 extending from said member upward as shown, and it Will therefore be clear that when this'lever 10 is forced downward ly the toe 9 will operate within the recess 8 to throw the bolt 7 inwardly to retract it from said rack. v

Slidably guidedwithin the bottom of the casing is a vertically disposed independent plunger pin 11, which moves freel through a boss 12 preferably formed on the casing, to contract the sill denoted by 13.

This plunger 11 is a pin or' short bolt and is provided with a head 14 whose upper surface is spherical as shown.

The operating member 3 has at some suitable location along its lower edge portion a suitably formed surface, which, when said member is forced downwardly, contacts the head 14 and drives the in 11 against the sill 13, and-, as'it is advisa le to exert considerable force against this head, a cam shaped member 15 is formed integral with the lower edge portion of the part 6, and the pin 11 is located in nearly the same vertical plane with the post 4, so that, when the lever 10 is forced downwardly,lthis cam 15 will exert great force against the head 14, owing to the very considerable leverage infavor of the operator, and this will both retract the latching member 7 and will also raise the sashfrom the sill, as shown at Fi ure 2. By easy manipulation, the lever 10 is held in its depressed position and force exerted against the stationary lever 16 to raise the sash.

This lever 16, in substantially all sash holders, extends rigidly from the side of the equally as well with a pivoted latching member, and therefore, referring especially to Figures 3 and 4, there is illustrated a latch-,

ing member 17 that is lpivoted around the post 18 extending from t e casing one end of said member adapted to be swung into latching engagement with the usual rack on the window casing, while the other extremity is formed with a recessed portion 19 within which operates a toe 20 extending from the upper portion of the inner end 6 of the operating member, and a coil spring 21 extends between this end of the member 17 and the top portion of the casing, which spring, like that heretofore described, serves to restore all the parts to normal position with the member 17 in latching *gengagement with said side rack.

The operation of this construction shown at Figures 3 and 4 is precisely the same as that heretofore described with respect to the structures shown at Figures 1 and 2.

Referring particularly to Figures 5 and6 the constructions therein shown are the same as those shown at Figures 1 and 2, with the sole exception that a lever 22 extends rigidly from the lower portion of the casing instead of from the top portion; so that the operator may grasp both levers in his hand, and by asqueezing action, and alsothe exertion of a downward force, bring the parts into the position shown at Figure 6, with the latch lease, comprising a casing having a stationary lever extending therefrom, an operating member pivoted within said casing and having a lever extending therefrom in j uxtap osition with respect to the stationary lever, a separate latching member movable in the casing, connections between said latching and operating members whereby the down ward and upward swinging of the operating member lever will effect the unlatching and latching movements of the latching member, a spring which acts to effect the latching movement and to restore the parts to normal positions, a vertically disposed independent plunger pin slidably guided within the bottom of the casing and adapted to be forced downwardly by the bottom portion of the operating member with a camming actionwhen the latter is forced downwardly to effect the withdrawal of the latch member.

In testimony whereof I afiix my signature hereto. JOHN L. ARMSTRONG.
