IVIOSQUITO-BAR FRAME.

SPECIFICATION forming part of Letters Patent No. 229,071, dated June 22, 1880. Application filed November 20, 187D.

To all whom it may concern:

Be it known that I, DAVID F. AGNEW, of Allegheny, in the county of Allegheny and State of Pensylvania, have invented a new and useful Improvement in MosquitoBar Frames; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to an improvement in mosquito-bar frames; and it consists in the novel combination and arrangement of parts, as will be hereinafter fully described and claimed.

To enable others skilled in the art to make and use myinvention, Iwill proceed to describe its construction and operation.

In the accompanying .drawings7 which form part of my specification, Figure l is aside elevation of a bedstead provided with my improved detachable mosquito-bar frame, representing the bows of the frame lowered with the mosquito bar or netting stretched over it. Fig. 2 is a transverse section of the bedstead, representing the bows'of the frame in an elevated position, with the mosquito bar or netting removed. Fig. 3 is an enlarged detailed view of the post, hinge, and bows. Fig. 4L is a `front view of the detachable hin Oe, representing the bows removed therefrom. Fig. 5 is a perspective view of the detachable socket for the reception ot the lower end of the detachable posts. Fig. `6 represents a section of the netting with the exible metallic cord or chain hemmed therein. Fig. 7 is a perspective View of the frame or body of the hinge.

In the accompanying drawings, Arepresents the bedstead, which is of the ordinary construction.

To the head-board or side rails of the bedstead A are secured the metallic sockets C for the reception of the detachable posts B. The socket C is secured in position by means of screws, which pass through the openings m, and the post is supported and held in position by means of the flanges n, which form a tapering cavity corresponding to the taper of the lower portion of the post B.

The post B is made tapering from each end toward the center, so that the lower portion will wedge firmly in the sockets C, and the hinges D become firmly wedged upon the upper portion, over which pass the hinges D through the socket-s e, which taper from the bottom edge toward the top edge.

The body ofthe hinge is provided with a spring, lL, as shown in Fig. 4, which is held in position by means of a screw, which enters the opening g, shown in Fig. 7.

The lugs of the body of the hinge D are provided with openings c for the reception of the pintle l, upon which are pivoted the bows 1 2 3 4l, between which are placed metallic washers.

The ends of the bow 1 are secured in a rectangular plate, o, which'is pivoted on the pintle l, withf its inner end resting against the lower end of the spring h, as seen in Fig. 3, when the bows are elevated as represented in Figs. 2 and 3, the spring acting against the under side of the rectangular piece o, when the bows are lowered, as shown in Fig. 1. By this arrangement of securing the ends of the bows 1 in the outer end of the rectangular piece o, and the inner end of it resting against the spring h, the bows are held in a fixed position, and by the spring acting against the under edge of the rectangular piece o the bow l is held in position when it and the bows 2 and 3 are in the position shown in Fig. l. The bow tis secured in an elevated position by means of cords p passing around the bow and the upper end of 8o the posts B; but other instrumentality may be employed for securing the bow 4 in an elevated position, as indicated at K in Fig. 3, in which a metallic loop or staple is used.

To the bow 4. is attached at each side a cord, r, to which are attached the bows 1, 2, and 3, for the purpose of holding the several bows in proper position with relation to each other, which is clearly shown in Fig. 1.

To the bow 1, at s, are attached cordst, which pass over pulleys a in the posts B, and are united at x for the purpose of forming drawcords for elevating the bows, as shown in Fig. 2.

The bows may be lowered into the position represented in Fig. l by simply pulling on the bow l.

The netting 'i is constructed of the usual material and in the form represented in Fig. l.

IOO

cordin g in the border of the netting is for theY I claim as of myinvention, and desire tosccure Vby Letters Patent, is-

In a mosquito-bar frame, the combination of the sockets C, posts B, hinges D, consisting of the sockets c, perforated lugs ff, spring h, and pintle Z,1"1Xedbow 4, pivoted bows 2 3, and bon7 l, provided with the pivoted rectangular piece o, the several parts arranged relatively to each other substantiallyin the manner herein shown and described.
