TQ' JALL WHOM IT MAY CONCERN:

Be it known that we, JOHN W. CRAW, of NOIWZLlh', in the State of Connecticut, and ABEL S. RANDOLPH, of Plainfield, in the State of New Jersey, have invented, made, and applied to use a certain: new and useful improvement in Mosquito and Fly-Nets; and we do hereby declare the following to be a. full, clear, and exact description of the said invention, reference being had to the annexed drawing, making part of this specification,

wherein- Figure 1 is an elevation of a window with our mosquito-net fitted thereto, the side slides being partially in section.

Figure 2 is a sectional plan of the same at the line a: x; and

Figure 3 is a separate elevation of one of the side bars receiving the net.

lhe object-of our said invention is to-allow easy access to the blinds outside the window, to allow the window to he opened or shut at pleasure, and the netting always to he in place for use, and notoin the way or liable to injury.

We make use of a roller, upon which the netting is wound by a spring, a headhar,'to which the moving edge of the netting is attached, and slides fixed to the edges of the window-casing, and receiving the ends of the head-her; and said head-bar is fitted so as to be connected, removahly, to the bottom rail of the sash. By this construction the spring-roller keeps thenetting under tension, taking up the slack as the sash is closed, the side slides keep the head-bar and edges of the netting in place, and when the head-bar is disconnected from the sashthe window can be opened without'spreading the netting, said netting remaining in position, but in a small compass, sees not to be in the way.

In the drawing, a represents a window-frame of any desired character; I) and c are the'sashes, fitted to slide as usual; 2' k are our grooved side slides, attached to thestop-bead of the window-frame; e is the roller for the netting f; and is the head-bar, perforated with holes, so as to set over pins that are introduced in the lower rail of the sash. The ends of the' head-bar 9 pass within g ooves in the faces of thoverticnl slides z'k, that are attached to the stop-heads or frames a,- but atthe lower part of said slides i k the rib on the side of the groove is removed, as seen in fig. 3, so thatthe head-oar 9 can be drawn off or put'upon'the pins 2 in the sash-rail b. The slide k'is made hollow, so as to receive a contractile India-rubber cord, 3, or other spring, from which a cord, 4, passes to the spool 5; on the axis of the rollere, so as to rotate said roller, and-wind up the netting as the sash 6 is closed. The act of opening said sash 6 draws up the head-bar g, and spieads the netting; and the cord 4 is wound upon the spool 5 by this movement, and the spring 3 distended. The edges of the netting, remaining in the groove of the slides Us, and under tension, are sufiiciently tight to keep out 'flies, mosquitoes, &c.

This netting can be applied to the top or bottom sash, or to a sliding door or sash, and allows access with facility to the blinds outside the window, and does not obstruct the light when the window is closed.

If desired, small ribs of whalebone or skirt-spring ma; be introduced horizontally in the nettinz. at suitable distances apart, to keep the edges of the netting into the grooved bars 2' and k.

We'do not claim a spring-roller and a bar connected to. the sash and receiving the moving end of the netting, as these have been used.

What we'claim, and desire to .secure by Letters-Patent, is--- The bar g, in combination with the slides tile and spring-roller a, when the ends of the bar g are formed to 'enter and slide in the slides i k, and said slides i I: are partially removed at their lower ends to allow the bar g to be removed from the pins 2, for the purposes and as set forth.

In witness whereof I have hereunto set my signature this twenty-sixth day of April, A. D. 1867. JOHN W. ORAW,

ABEL S. RANDOLPH.
