SAMUEL ROEBUCK, OF BROOKLYN, NEW YORK.

IMPROVED MOSQUlTO-CANOPY.

Speeication forming part of Letters Patent No. 38,339, dated April 28, 1863.

To all whom it may concern.'

Be it known that I, SAMUEL RoEBUcK, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Mosquito-Canopies and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in Which- Figure l is a side view of my invention; Fig.c2, an inverted plan of the same; Fig. 3, a side view of the same in a folded state.

Similar letters of reference indicate corresponding parts in the two gures.

This invention relates to an improvement pertaining to the frames of mosquito-canopies for bedsteads; and it consists in a peculiar manner of constructing the metallic head in which the arms ot' the device are fitted, whereby the head is rendered capable of being cast in one piece at a triiiing expense.

' To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a metallic head, in which wooden arms B are tted radially at equal distances apart. This head is formed with a socket, a, at its upper part to receive a wooden knob, O, said knob being secured in the head by a screw, I), which passes up through the center of the head from its under side. (See Fig. 2.)

From the lower edge ot the socket a, a ange, c, projects downward in an inclined or flaring position, as shown more particularly in Fig. 3. This flange o extends all around the lower ed ge-of the socket a, and it is formed with a series of loop-projections, d, and shoul ders e, the latter being on the outer side of the liange and extending down about one-half the length ofthe loop-projections d. The shoulders e are between the loop-projections, and the former serve as bearings for a wire, D, which encompasses the flange and is secured at its ends by twisting the latter around each other, or by any other suitable fastening or connection. The loop-projections cl are formed with an indentation, f, at their outer surfaces, to receive the wire D, as shown clearly in Fig. 3.

The arms B are of wood, of cylindrical form, and tapered at their inner ends, as shown at g. These arms are fitted in the loop-projections ol, and are secured therein by the wire D, which passes through them. The arms are allowed to work or turn on the wire D that is to say, move up or down-but they are prevented from descending below a certain point in consequence of the inner ends of the arms coming in contact with the under side of the socket a, and the arms when at their lowest point have a slightly-inclined position, as shown clearly in Fig. 1. The arms are of different lengths, so as to form a rectangular frame, over which the netting E is fitted, the latter extending entirely around .the bedstead, the arms being made of such a length as to admit of that result. The head A is suspended from the ceiling by means of a cord, G, which passes over a pulley secured in the ceiling, directly over the center of the bedstead.

By constructing the head in the manner as set forth it will be seen that it may he cast all in one piece at a trilling cost, and the frame of the device, which consists simply of the head and arms may be manufactured at a small cost, for the arms, may be fitted in the head very expeditiously. All that is required to effect that result is to pass the wire D through the holes in the arms and adjust the wire in the indentation f in the loop-projections d, and underneath the shoulder e of the flange c. By thus constructing or forming the head A, the arms E, when the device is not designed for use, may be folded back in compact form, so as to occupy but little space, as shown in Fig. 3, 'and they may in consequence be boxed for transportation at a moderate expense, with the parts all adjusted together for use.

Having thus described my' invention, what I claim as new, and desire to secure by Letters Patent, is-

The head A, formed of a socket, a, and flange b, the latter being provided with loopprojections d and shoulders e, the loop-projections being provided with indentations f, which, in connection with the-shoulders e, hold the wire D in proper position, for the purpose specified.
