WIN-DOW LATCH AND DRAFT PLATE.

Application filed October 5, 1926. Serial No. 139,628.

his i vention re ates to impreveme ts uble-hung wind w sashes, and h to its je o pr vide metal steeri g plate and ndow latch f rming an integmlcoin inetion, and operating in conjunction With the er and upper sash, and which has for ts object'to remedy and eliminate several obj ctionable condition inevit ly f und existing in the use of such windows aforementioned. 1

Such needs and purposes will hereinafter more fully be described and pointed out.

The bottom part, or metal steering plate, will thus eliminate all dust and draft from the corners of double hung windows at meeting rails, where sashes meet parting strip on sides of jambs, while the upper part, or latching member, will securely interengage such windows in any desired position.

With the further appliance of an independent :device, not described, shown, or claimed, herein, as it may consist of a simple hook, or similar apparatus, fastened to the sash, and adapted to engage recesses .01 notches in the frame, this invention will practically render such Windows burglar-proof, and the combined adjustmentmay be to the effect that no person will from outside lie able to enter, or operate the combination-lock as thus described.

Said combination will furthermore ,on account of its special constructionact as a steering guide tor loose and rattling winbinationwith the former, I shall in this application confine my description and claims. to said improvements 1n WIDClOW latch and.

draft plates.

In a slightly modified form the latching member of my device may be used instead of the ordinary window clasp, as .I in this case use a special toot-plateas shown clearly in Fig. 6.

With the above and other objects in view,

at the same time forming an integral com this invention consists of the novel features of constructlon, combination and arrangements of parts, hereinafter fully described, cla med, and illustrated in the accompanying drawings iorming parts .of this specification, and in which similar characters of reference indicate corresponding'parts in all views, and in which;

Figu e 1 is a perspective View of my invention; Figs. 2 and .3 illustrate the construction of the combined latch mechanism;

Fig. 4 is a top view of the combined device; Figs, 5 and 6 show my device in a modified form. Fig. 7 is a detail view of two latch members.

Referring more particularly to the drawings, 17 designates a fastening member formed integrally with the plate 10, the

latter indicates ametal plate adapted to be 1 fastened on top at one flipper corner of the lower sash of a doublelmng window. Said plate is provided with a substantially square, cutout portion 11 .to allow space for, and 03 ,111 a snug fitting with, the parting strip 15 .of the window This plate has a further reduced portion as shown at 12, providing suff cient space for the sash cord 16, for which purpose it has at its base, been formed with a slight, inward curvature 13. This reduced portion further takes in space, as indicated at 14, in order to permit the passing-0f the sash pulley, when .the sh i op ned a d rai t the t p of a window frame.

The said fiastening member 17 comprises a frame 18 side walls 19 and a lever or nd e 20- To sa d le i p v ta ly engaged, in the manner shown, a stop-member 21, and a release member 22. Said lever is turnaibly' seatedon an axle 23,, the latter being rigidly Supported by the walls 19. It will be noticed that the members 21 and 22 have .a reenforced bearing 241211; the section where the engagement with-the lever takes place. Said lever connects with members 2land 22 by means of bifurcated sections 25- formed on the latter and pivotally connected by means of axle pins .26. V
