IMPROVE!) WINDOW-GUARD AGAINST FLIES AND MOSQUITOES.

The Schedule referred to in these Letters Patent and making part of the same.

www

To all y'1t-hom Iit Imay concern Beit known that I, EDGAR L. Loenn, of Central Falls, in the county of Providence and State of Rhode island, have invented a new and improved Device for Keeping Out Flies and Mosquitoes; and lI hereby declare that the following specification, taken in con` neotion with the drawings, making a part of the same, is a full, clear, and exact description thereof'.

4.l'Pigure 1 is a view ofthe window from inside.

Figure 2 is a vertical section showing the window partially open.

The object of my invention is to produce a self-adjusting device, which when app/lied to a window shall render that space between the two sashes which is made by the raising of the one'or the dropping of the other sutiiciently tight to4 pre'fcnt the ingress of flies or mosquitoes.

rlhe glass, being set into the sash and not parallel with the outside -o' the same, there will he no open space between the top part of the lower sash and the vlower part of the top sash while they remain in contact with each other, which they do when the window remains closed but if either sash` be opened so that the contact is no longer 4preserved an openespace will 4be left equal in width tothe distance of the glass from the outside of the sash.

it is now almost a universal custom during the warm season to keep the windows open except in stormy weather, and t place within the open space anetting of wire or other material to keep out the ies and mosquitoes, which in many localities are very numerous, and in nearly all are attracted to the house during the evening by artificial light. These insects' finding their way through the open space eiect-nally checked by the net-ting, make use of the Space between the sashes already described.

My invention is attached to the under side of the upper sash, as shown in iig. 1, 'by the metal end pieces,.\'vhich are so constructed as to also act as guides to the horizontal lip A, which, being cut out to receive the perpendicular part of the sash B, shuts tightly against the glass, and is held in that position by springs C C' upon each end ofthe same.

The space now left between the lip A and the upper sash is closed by a strip, E, attached to the lip A, or both may be made iu the same piece.

The operation of my invention is as follows:

The springs press the lip A against the glass, but not with suiiicient tince to prevent the sliding of' either sash.

In order, however, to have the free use of the window it is oftentimes necessary to force back the lip A,

which slides between ythe guides :1: and x' to allow the the lip A two halilcircular pieces of metal, H and H', which being acted upon by the piece F pushes back the lip A until it has passed them, when the lip is again pressed against the glass by the action ot' the springs.

What l claim as my invention, and desire to secure by Letters Patent, is-

The device herein described for closing .the space between the upper and lower sashes of a window for the purposes specified, consisting in the combination and aran'gement of the lips A and E, the springs C and C', the guides :c and 1v', and the curved rods H and H', in the manner substantially as set forth.
