IMPRCVEID MSQUITO-BR I. The Sche'ule referred to in thse LettersPatent and making part: of the same.

'Be it known that I, HENRY SEABLE, `of Washing ton, in the vcounty of Washington,.in the District of i Columbia, have invented a newand` improved Mode `of Constructing Mosquito-Bar Frames; 'and Ido hereby declare that theY following is a fulland exaetde- `seription thereof, reference being had4 to the accomf panying drawings, and to theletters of reference marked theieon. i v

` The nature of -my invention consists in constructing an arehed,`sp1ing mosquito-bar'ame, by providing springs, made of wood or metal, of any desired length to formthe frame, the "springs being held together inA n the eentre bya screw-eye, forming a pivot, on which` they turn, and then by fastening cordsv of a proper "length to theends` of the springs, 'and drawing the cord inward, so as to bend the springs into anarchform, and get the force of the springs against the cords; andethen fastening the cords by looping them on to the `ends of the centre spring, I have a'substautial y archedtop frame complete; and, by `vunlooping the cords, the springs may be Abrought together, with `the ,netting attached, so that the netting may befolded or `wound`around the springs when not in use, or for transportation.

Figure 2 showsa top view of the springs when folded together, with the netting removed.

Figure 3 `shows the netting wound around the springs. i i ,n i n p A, B, and C, iig. 1, show the springs which form theframe. n K,

D D show the end'eords.

To enable others skilled in the art to make and useV n ,my invention, I will proceed to4 describe its construc- Jtion and operation, by referring to the annexed drawings, in whichi 1 Y i y Figure 1 is a perspectiveiview of my 'mosquito-bar frame, with the netting attached.

Witnesses: l

E F and G 11 show-the eords'on the sides.

I shnws the adj listing-cord, which is looped onto the ends of the centre spring C, by means of which the centre spring is adjusted.

. -J, iig. 1, shows a serewfeye, on which the springs work, and to which a cord is fastened, for the purpose of suspending the frame.

K shows the netting, which isfastened to the cords around the frame, and parted on each side, and also over the top of the frame, the netting over the topv of the frame being lapped, and held together by tying, or

vin some way that itfmayvbe'easily unf'astened.

Now, it will be seen, that the "cord I kbeing of a properlength, and looped on to the. ends of the spring C, the'spring C is bent, so as to 4form an arch ;v and, by making the cords D D, fig. 1, of a proper length, and having .them fastened to' the ends vof' the springs A and B, and drawing them inward, so as to bend them into the form of an areh, and then by looping the cords E F and G H to the ends of the spring C, I have an arched frame, and the springs, acting against the cords, keep them stretched, and in their proper position.

By unlooping the cords from the ends ofthe spring C, and unfasteningthe netting on .the top of the frame,

the frame may be closed up, as shown, iig. 2, and the` netting may be folded or wound around the springs, as shown, fig. 3. 'Y What I claim as my invention, and desire to secure byLetters Patent, is-

The combination of three or more intersecting springs, A B C, with a transverse adjusting-conifl,

and with lateral cords, D, D, E, F, G, and H, the

'Whole constituting an adjustable arched mosquito-bar frame, substantially ashereiu set forth. t HENRY SEARLE.
