CANOPYNFRANIE.

SPECIFICATION forming part of Letters Patent No. 678,789, dated July 16, 1901. Application filed January 29, 1901. Serial No. 45,188. (No mccl) I all whom t may concern:

Beit known that I, WASHINGTON T. JOHN- STON, of I-Iouston, in the county of Harris and State of Texas, have invented a new and useful Improvement in CanopyFram es, of which the following is a specification.

My invention is in the nature of an improved canopy-frame for supporting amosquito-net or drapery of any kind; and it con- Io sists in a very simple, cheap, strong, and light construction for this purpose which I will now proceed to describe, with reference to the drawings, in which- Figure l is a perspective view of the entire frame set up. Fig. 2 is an enlarged detail of the connection of the horizontally-project ing arm with the vertical su pporting-post and cross-bar, and Fig. 3 is an enlarged detail of the connection of the outer end of the horizo zontally-projecting arm with the outer crossbar.

In the drawings, A A are two posts which' may be erected vertically upon any suitable base, as at B, or which posts may be bedz5 posts themselves.

O C are the side arms, D the inner crossbar, and E the outer cross-bar. The side arms are each made alike out of a single piece of bent steel wire. Each arm has at its up- 3o per side a straight horizontal section 1, which at its outer end is bent into an oval eye 2 and is thence extended inwardly and downwardly at an angle at 3 and then is bent at an obtuse angle at 4 up again to close proximity to the upper straight member l, at which point the upper and lower sections are embraced and locked together by a loop or link 5, of the same material, and from this point the wire is bent at an angle downwardly 4o again and enters a socket or hole in the post some distance below its upper end. The inner end of the upper section l is extended across and lies in a notch or groove 6 in the upper end of the post and is then bent downwardly behind the post at 7 and then has its end turned inwardly toward the post and enters a rear socket 8 in said post. This connection of the upper and lower members of the side arm to the post makes a braced cantaliver construction that causes the arms to be maintained in a horizontal position even when there is considerable weight on their outer ends, the connection to the post being such that weight on the arms has not only a tendency to force the lower member more tightly into its socket, but also pulls the bent end of the upper member more flrmlyinto its rear socket and the notch at the upper end of the post.

To brace the two posts together and hold 6o the inner ends of the arms apart, a cross-bar D is formed at each end with a ferrule, and a hook d is fixed in each y'end thereof, which hook passes around and embracesa similar ferrule on the upper end of the post, while the end of the hook abut-s against and forms a side bearing for the downwardly-bent end of the upper member of the arm that forms a reciprocally stitened and braced joint.

To hold apart and brace the outer ends of 7o the horizontal arms, an outer cross-bar E is provided, which has valso a metal ferrule on each end with a projecting wire e, which passes through the eye at the outer end of the wire arm and is then bent atl-ight angles, so as to lie in the crease or space between the upper and lower wire sections of the arm, so as to lock the said cross-bar against rotating and also to hold the cuter ends of the arms against spreading apart.

With a canopy-frame thus constructed a very light and cheap device is provided,- which is easily portable and which may be conveniently set up or be taken apart and compactly folded for transportation.

Having thus described myinvention, what I claim as new, and desire to secure byLetters Patent, is

l. In a canopy-frame,' a horizontal supporting-arm made of wire in a single piece, 9o and formed of a straight upper section bent at the outer end into a loop or eye and then extended inwardly irst down, and then up to the straight section and coupled thereto by a link, and then extended downwardly to 95 connect with a post, the inner end of the upper section being also bent downwardly and its end turned forwardly to adapt it to enter a rear socket in the supporting-post substantially as described.

2. In a canopy-frame, the combination of a Vertical post having a notch in its upper IOO end and a socket both on its front and rear sides near the top, and a horizontal supporting-arm made of wire in a single piece formed of a straight upper section bent at the outer end into a loop or eye and then extended inwardly, first down and then up to the straight section and coupled thereto by a link, and then extended downwardly and entered into the front socket of the post, the inner end of the upper section being arranged inthe notch at the top of the post and also bent downwardly behind the post and then bent forwardly and entered into the socket in the rear of the post, substantially as and for the purpose described.

3. In a canopy-frame, the combination of a Vertical post having a notch in its top and also a front and rear socket, a bracket-arm having two members one fitting in the front socket of the post and the other bent over the top of the post and lying in the notch, and bent down and entering the rear socket of the post, and a cross-bar arranged between the posts and having at each end a hook each having a'notch in its upper end and a' front and rear socket in its sides near the top, two horizontal bracket-arms made each of a single piece of wire bent on itself as described to form a double angle in its lower portion and a straight upper portion whose inner end is turned downwardly and forwardly and having the inner ends seated in the notches and sockets of the posts, a crossbar connecting the posts at their upper ends, and another cross-bar connecting the outer ends of the arms substantially as and for the purpose described.

VASHINGTON T. JOHNSTON.
