tJhlllED STATES CHARLES EUGENE BBINEY,

OF COVINGTON, KENTUCKY.

WINDOW-SCREEN LATCH.

Application filed July 1,

To all whom it may concern:

Be it known that I, OHARUZS E. BRINEY, a citizen of the United States, residing at Covington, in the county of Kenton and State of Kentucky, have invented new and useful Improvements in \Vindow- Screen Latches, of which the following is a specification.

The object of my present invention is the provision of an improved construction embracing a lower slidable window sash, and a window screen, and means under the control of an operator whereby when desired the sash may be coupled to the screen so that raising of the lower sash will be attended by elevation of the screen into working position, while lowering of the lower sash will be attended by a disposition of the screen in a pocket provided for its accommodation whereupon if deemed expedient as in the winter time, the lower sash may be uncoupled from the screen so that the said lower sash may be raised or lowered at will in the ordinary well known manner without any movement whatever of the screen.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part of this specification Figure 1 is a view showing my improve ment with the lower sash and the screen in their lower positions.

Figure 2 is a similar view of the lower sash and the screen raised.

Figure 3 is an enlarged detail section on the line 33 of Figure 1.

Figure 4: is an enlarged detail section at right angles to Figure 3 and on the line of said figure.

Figure 5 1s a broken plan view of the upper edge of the screen.

Similar numerals of reference designate corresponding parts in all of the views or the drawings.

In furtherance of my invention the window casing 1 is provided with a pocket 2 arranged below and in the same vertical plane as the lower sliding sash 3, and in the said pocket is adapted to be arranged a rectilinearly movable screen ft. In the up per bar of its frame the said screen 4 1s provided with pockets 5, and attached to the said upper bar and arranged over the said pockets 5-are flush plates 6 with aper- 1922. Serial No. 572,125.

tures 7 and cross bars 8, one cross bar to each plate.

Also in furtherance of my invention the lower sash is provided in its lower frame bar with chambers 9 one of wnich is clearly shown in Figure 4. It will also be noticed that the lower sash is equipped with headed bolts 10 of angular form in cross section, the said headed bolts being. introduced through openings 11 in the outer side of the sash bar and arranged at right angles to the chambers 9 and having their inner ends disposed and fastened in rotary caps 12 opposed to the inner side of the lower sash bar and equipped with handles 15. Keyed on the bolts 10 are latch arms 14 and mounted on the bolts 10 and'interposed between the heads thereof and the outer sides of the latch arms M are coiled springs 15. These springs 15 are designed and adapted to impose such tension on the latch arms 1 L that the said latch arms 14 will rest in their upper idle positions in the chambers 9 when the latch arms are adjusted to such idle positions.

In the practical use of my improvement it will be manifest that when the handles 13 are in upright positions as shown in Flgures 2, 3 and 1, the latch arms 14 by cooperation with the plates 6 will couple the screen 4 to the lower sash 3, and hence upward movement of the sash 3 will be attended by the upward movement of the screen I so that the said screen will effec tively bar the opening left by the raising of the sash 3. Likewise when the sash 3 is lowered to closed position the screen 4t will be moved down into the pocket 2 and entirely out of the way as well as entirely out of sight. When the handles 13 are turned to horizontal positions as appears in Figure 1, it will be understood that the latch arms 14 will rest idly in their upper positions in the chambers 9, and hence the sash 3 and the screen 4: will be uncoupled with the result that the sash may be raised and lowered in the ordinary manner without any movement whatever of the screen. This uncoupling feature is particularly advantageous for use in the winter time when screens are obviously unnecessary. It will be noted, however, that whenever it is desired to couple the screen t to the sash 3 the same may be accomplished while the sash 3 is in its lower position by simply of the construction and relative arrangen'ient of the parts embraced in the present and preferred embodiment of my invention in order to impart. a full, clear and exact understanding of the said embodiment. I do not desire, however, to be understood as confining myself to the specific construction and relative arrangement of parts inasmuch as in the future practice of the invention various changes and modifications may be made such as fall Within the scope of my invention as defined in my appended claim.

Having described my invention, What 1 claim and desire to secure by Letters Patent, is

A Window screen latch including a square headed member rotatable transversely of one side member, a handle removably mounted on one end of said headed member having a face for bearing contact with the sash member, a latch arm slid-able on the headed member and adapted tor rotation therewith to engage or disengage a keeper mounted on a cooperating sash nien'iber, and a coil spring mounted on the headed member between the latch arm and the head for normally holdingsaid latch arm in bearing contact with the sash member in opposed relation to the handle.

In testimony whereof, I atlix my signature.

CHAR-LES EUGENE BRINEY.
