IMPROVED WINDOW-SCREEN.

@the Stljrhult rrfettrh tu in illes ltttetsslttnt zmr mating glatt nf the smite.

TO ALL WHOM IT MAY CONCRN:

Be it known that I, Josnrn` G. BICKNELL, ofthe city of Cambridgeport, county of Middlesex, and Stat-e of Massachusetts, have invented a new and original plan forQVindow-Screens or Mosquito-Frames; and I do hereby declare that theifollowing is a'ull and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in covering the whole window, from the top to the bottom, so as to eiectually exclude mosquitoes or iiies, and at the same time have the window open at the top or bottom, as the occupant of the room may desire.

In order to do this I make a frame to cover the wholewindowfsnsh; this I call an outsideV frame, and isi marked A in the drawings. I next make an inside frame, ot' three pieces of wood, of one-half ot' the sizeA of' the outside frame, or smaller, as the case `may require, and hang it with hinges, or by putting screws through the top end of each upright bar into the outside frame. From the top ends of this frame I nail some small pieces of wood round the inside of the outside frame, to nail the netting to, and to hang the bottom frame to when hinges are used;` thus, showingthe outside frameall r'ound, it will be readily seen that this bottom or inside frame will open readily to enable a person to opena window o1' ,blinds easily, or to close the same. This inside frame is marked B in the drawings, and if wanted to be kept open it may be by putting a catch, G'r, on' the top or side of thet'rame, or by a cord, M, and hook N, as shown in the drawings. I-I, hinges.; S, spring-catch to hold the opening frame together when closed; K, knob; `r, screws by which the frame is fastened to the window.

Sectional drawing No. 2 represents a screen-t`ritme with smaller openings,- to be used in places where there is not room to swing one-half of the screen-frame into the room. I make these small openings to enable any one to open or shut blinds or windows with ease, and keep thescreen in the window.V At the same time it will be useful to have two of these openings in most frames, viz, one' at the bottom to open blinds through, and one near the centre of the frame to unfasten the sash from. The same letters of reference apply to this as to the other.

Claim.'

I claim the' combination of the outer frame A with the inner netting-covered frame B, fitted into it and hinged at its sides, all as and for ythe purpose described.

JOSEPH G. BICKNELL.
