' CANOPY-FRAME.

To all whom it may concern Beit known that we, GEORGE F. LINDSEY and GEORGE A. WILLIAMS, citizens of the United States of America, residing at Birmingham, in the county of Jefferson and State of Alabama, have invented certain new and useful Improvements in Canopy- Frames, of which the following is a specification.

Our invention relates to an improvement in collapsible frames for canopies.

The object of our invention is to devise an extremely simple and cheap method for flexibly connecting together the members forming the canopy frame to a central support, all parts being so arranged that the the plate and strung on a hinge ring orotherwise loosely connected beneath the plate. In order to prevent thearms from sliding down through theopenings 1n the plate when in collapsed position, 2'. 6., swung up to vertical position relatlvely to the plate, we provide means for connecting the hlnge means to the underside of the plate. We prefer the hinge ring as the simplest and cheapest manner of hinglng the several frame members to the center plate, but other equivalent means may be employed.

Our invention further comprlses the details of construction and arrangement of parts which in their preferred embodiments are hereinafter more particularly descrlbed and illustrated in the accompanying drawings, in which Figure l is a top plan vlew of a canopy frame in extended position. Fig. 2 is an enlarged bottom view of the center plate and fastenings for the frame members. F 1g. 3 is a vertical sectional view taken on the line m-m of Fig. 1. Fig. 4 is a detail sectional View of the center plate. Fig. 5 is an end elevation of the plate.

Similar reference numerals refer to similar parts throughout the drawings.

The center plate 1 is preferably formed of a steel plate which has a series of radial seats 2 pressed therein, which seats extend Specification of Letters Patent. yate tgdga 11 191 Application filed 0ct0b eri7, 1914. Serial No.

fromthe periphery of the plate to a point near 1ts center and each is provided with a slot 3 at its inner end. The central portion 4. of the plate has a central opening 5 to receive the threaded shank of the hook member 6 by which the canopy is adapted to be suspended. The frame is formed of a series of arms or members 7 adapted to fit snugly into the seats and the inner ends of which arms are adapted to project through the slots 3 to a point below the plate. Preferably the arms are formed of metal rods, the inner ends of which are bent to form loops 8 which are passed down through the slots 3 and project sufficiently below the underface of the plate so that a ring 9 may be passed through the several loops 8 and thereby afford a cheap and effective means for hinging them below the plate. The ring 9 is held in position against the underface of the plate 1 by any suitable means, preferably by a plate 10 which serves as a washer for the nut 11 which is screwed on the threaded shank of the hook 6 and attaches the latter to the plate 1. The seats 2 are preferably formed by pressing a steel plate, but obviously they may be formed in the plate in any desired manner. The outer ends of the arms or rods 7 are provided with loops 12 to which the canopy, indicated formally by the dotted line 13 in Fig. 1, is attached. It is not essential that the washer plate 10 should engage the ring 9 but it is preferable as otherwise, when the frame members 7 are swung upwardly to collapsed position, see doted lines Fig. 3, they will be free to slide down through the slots 3 in the plate and thereby become temporarily displaced relatively to the center plate.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is

1. In a collapsible canopy frame, a center plate having radial seats in its upper periphery and openings in line with said seats, frame members adapted to fit in said seats and having their inner ends adapted to project down through said openings in the plate, and means to hingedly connect the several inner ends of said members to the underside of said plate, substantially as described.

2. In a collapsible canopy frame, the combination with a center plate having a series of radial seats in its upper face, frame members adapted at their inner ends to fit in said seats and having eyes at their inner ends, said plate having openings through which said eyes project below the plate, and a common ring passed through the eyes of said members below the plate and serving to hingedly connect them to swing from vertical to horizontal position relatively to the plate, substantially as described.

3. In a collapsible canopy frame, a center plate formed of pressed metal and shaped to provide radial seats extending from its periphery to points adjacent to its center, said seats having openings at their inner ends, frame members formed of metal rods adapted to fit snugly in said seats and having their inner ends bent to form an eye Copies of this patent may be obtained for adapted to pass through said openings in the seats, a ring which passes through the several eyes below the plate, a hook which is provided with a screw shank which passes downwardly through the center of the plate, a nut and washer to connect said hook to the plate, said Washer being adapted to en gage and hold the ring adjacent to the underface of the plate substantially asv described.

In testimony whereof we aflix our signatures in presence of two witnesses.
