THADDEUS S. SCOVILLE, OF NEW YORK, N. Y.

MOSQUITO-BAR.

Specification of Letters Patent No. 27,236, dated February 21, 1860.

To aZZ whom t may concern:

Be it known that I, THADDEUs S. ScovILLE, of New York, in the county ot New York and State of New York, have invented a new and Improved Mosquito-Bar; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification, Figure l, being a plan of my improved mosquito bar, applied to a bedstead, and lowered over the bed; Fig. 2, a side elevation thereof, in the same position; Fig. 3, a side elevation thereof, represented as raised away from over the bed.

Like letters designate corresponding parts in all the iigures.

The mosquito bar may be applied to any ordinary bedstead, A. To the tops a, a, of the head posts, or other convenient parts of the bedstead, are secured vertical supporting rods Z9, b; and on these rods respectively are situated adjustable supporting blocks g, g, which are secured at any desired height on the rods, by means of set screws h., ZL, as represented in the drawings, or in any other convenient manner. On these supporting blocks rest hinges f, f, arranged so as to turn horizontally on the rods Z), o, and vertically, on joints m, m. To these hinges is fastened the curtain-frame, which is of the proper form and size to cover the bed, and is conveniently made of a border wire, or rod, c, and diagonal or roof wires (Z, CZ, for suitably supporting and suspending the curtain, indicated by red lines in the drawings. On the top of the rods Z), Z), are secured pulleys 7c, ZJ, so as to turn horizontally thereon, and thereby adapt themselves to any position in raising and lowering the curtain-frame. Cords z', z', are respectively fastened to the foot corners of the curtain-trame, extend backward therefrom over the pulleys lo, la, and thence downward through the curtain, and toward each other, till they are united, substantially as shown in the drawings. To these united ends of the cords, is attached a balanceweight Z, of such size, that when the curtain-frame and curtain are turned up, away from over the bed, thereby bringing their center of gravity nearly over the points of support, they will be overbalanced by said balance-weight. The balance-weight Z, may be covered with a tassel, as represented in t-he drawings, or be otherwise ornamental. Thus, by simply drawing the balance-weight down, the curtain-frame and curtain are turned away from over the bed, when the occupant desires; and by simply raising the balance-weight, the curtain-frame and curt-ain fall back, by their own weight, to their horizontal position again. In order that the curtain-frame and curtain may thus fall back, by their own weight, it is necessary that, when fully raised, they should not be quite vertical. They may also be kept from falling below a horizontal position, by any convenient arrangement; one method being' to have knots, or stops, on the cords 2'-, z', strike the pulleys Zu, 1, as shown in the drawings,

IVhat I claim as my invention and desire to secure by Letters Patent, is-

The combination and arrangement of the supporting posts Z), Z), adjustable doublyturning hinges, f, f, curtain-frame c, (Z, cords z', z', pulleys la, la, and balance-weight Z, substantially in the manner and for the purpose herein speciiied.

In witness that the above is a true specication of my improved mosquito bar, I hereunto set my hand, this 17 th day of OC- tober, 1859.
