Letters Patent No. 96,7 54, dated November 9, 1869.

IMPRovED ADJUSTABLE wmnowfscnnnw.

The 4Schedule rexerred to in these Letters Patent and making part of the-same.

` To all whom, 'it may concern:

Beit known that I, BENJAMLN J. WILLIAMS, ofl

the city and `county of Philadelphia, and State of Iennsylvania, have invented a new and improved AdjustableWindow-Screen; and I do hereby .declare that the following is a full, c1ear, and exact descrip# tion of the construction and operation of the same, reference being had to the accompanying drawings, making a part o f this specification, in which- Figure 1 is tn-inside view of screen, when adjusted and fastened tol window. A

Figure 2 is an outside view of screen.

Figure 3 is a view, in detail, of grooved strip.

Figure 4 is an edge view of screen.

Like letters, in the figures of the drawings, indicate like parts.

My invention, A, relates to the class of adjustable window-screens, for excluding mosquitoes and other insects from houses; and consists of a centre or stationary screen, with supplemental screens, movable in guides, andadjustable i'om each side thereof, and having the outer side-bars of the frames provided with tongued edges to it grooved strips, the latter to be screwed on to the beads of the window-jambs, thus enabling the Screen vto be adjusted and fastened at' either top or bottom :of window, with greater convenience than can be by pins or otherwise.

I construct and operate my'invention as follows:

'A is the stationary screen.

RB, supplemental screens, which move in guides a a, at top and bottoni of stationary screen, and having the outer side-bars of the frames provided with tougned edges, b b.`

O O are the grooved strips, to bescrewed on to the beads of the window-jambs. These str ips will extend up tothe meeting-rails ofthe sash, or up to the top of two witnesses,

of the window-frame, so that the screen may be se cured at either -top or bottom of window, as may be desired. Y

The stationary .screen is provided with set-screws, c c c c, to fasten the supplemental screens, when adjusted with their tongues, to t -the grooved strips, and has a movable bar, D, with tongued ends, to t and'move in grooves of the top and bottom bars of the frame, for preventing the screen from being pressed in by the wind or otherwise, so 'as to exclude any .possibility of insects from gettingin the window at this point, by bringing the movable bars-opposite those ot' the supplemental screens. LA

As the setserews c and movable bars D are shown and claimed in the patent of D. H. Hurlburt, J une 1,

1869, No. 90,845, of course Ido not appropriate them as parl: of my invention, but describe them simply to show their connection with it;

I do 'not claim, broadly, an adjustable windowscreen, as I am aware of the same being shown in the patents of Abner Magoun, February 20, 1866, No. 52,726, and I). H. Hurlburt, June l, 1869, No. 90,845; but

What I do claim, and desire to secure by Letters Patent, 'is- The stationary screen A, with supplemental screens B B, having the outer side-bars of the frames thereof provided with tongued edges b, in combination with grooved strips C, substantially as set forth.

As evidence that I claim the foregoing as my invention, I have hereunto set my hand, in the presence BENJN. J.WILLIAMS. Witnesses:

J As. J. OROMWELL,

THOMAS D.- SNYDER.
