WILLIAM CARTER, OF LONDON, ENGLAND.

UMBRELLA AND PARASOL.

SPECIFICATION forming part of Letters Application filed May 7, 1881.

Patent No. 244,545, dated July 19, 1881.

(No model.) Patented in England April 4, 1879, in France October 4, 1879, and in Belgium October '7, 1879,

To all whom it may concern:

Be it known that I, WILLIAM CARTER, of London, England, have invented new and useful Improvements in Umbrellas and Parasols, (for which I have obtained a patent in Great Britain, No. 1,316, bearing date April 4, 187 9, a patent in France, No. 133,011, hearing date October 4, 1879, and a patentin Belgium, No. 49,487,bearing date October 7, 1879,) of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to improvements in umbrellas and parasols, and is designed to pro- .vide better means than any heretofore in use for securing the upper end or tip of the ribs to thefixed ring or top notch, and for securing the lower end or tip of the stretchers to the sliding piece or runner.

It also relates to forming the lower end or tip of such ribs as are made with a groove running lengthwise, as in the so-called well-known paragon -frames, with a flattened portion, whereby such ribs will lie closer to the stick when the umbrella or parasol is closed than heretofore.

The said invention is illustrated in the accompanying drawings, in which Figurel represents a portion of an umbrellastiok and the top notch and runner, and shows my improved ribs and stretchers applied thereto. Fig. 2 is an interior view of the upper end of a rib constructed according to my invention; and Fig. 3 is a longitudinal section of the top notch, showing my improved ribs attached thereto. Fig. 4 is a side view of portions of a stretcher constructed according to my invention, and Fig. 5 is an interior view of the same. Fig.6 shows the method of securing the stretchers to the runner. Fig. 7 is a side view, and Fig. Sis an interior view, of the lower or outer end of an umbrella-rib constructed according to my invention. Figs. 2 to 8 are drawn to an enlarged scale.

Like letters indicate the same parts through out the drawings.

a represents the stick of the umbrella, l) the top notch, and c the runner. d d are the ribs, and e e are the stretchers, for the same.

In carrying my invention into practice, instead of forming the said ribs and stretchers with thin, flat, and elongated ends, to be attached to the top notch and runner, I make the said ends or eyes of a round or curved form, as shown at d e, and of a comparatively great width or thicknessthat is to say, considerably thicker than these parts have heretofore been made. This form is obtained by turning over a portion of the metal of which the rib or stretcher is constructed, an aperture being left for the passage of the ordinary wire for securin g the tip to the top notch or runner. These eyes or ends d ore are preferably formed of the same or nearly the same width or thickness as the ribs or stretchers, and fit into apertures b c, of corresponding width, provided in the top notch, 72, and the runner c. The said top notch and runner are somewhat similar to those heretofore constructed, but are smaller in diameter, the apertures therein are wider, and the projections are deeper than those in the top notches and runners heretofore employed. The tips or ends d and c are secured to the said top notch and runner by passing a wire, f, through the aforesaid tips or ends in the ordinary manner.

I prefer to form the runner with a curved flange or ring, 0 upon whose upper edge the ends 0 of the stretchers rest when secured in position, as shown in Fig. 6.

It will be seen that by forming the tips or ends d and e as above described, and by constructing the ribs or projections b and c on the top notch and runner deeper than heretofore, I insure a larger bearing-surface for the ribs and stretchers than is possible with the flat thin heads heretofore employed, and the ribs and stretchers therefore open and close in a direct manner without any liability to be come crossed, twisted, or obstructed. Moreover, by forming the top notch and runner of small diameter, as above described, I obtain the further important advantage of causing the ribs and stretchers to lie closer to the stick when the umbrella is closed than heretofore.

Each rib d and each stretcher e is formed of 9 5 of the said ribs and stretchers, as shown at (l 0*, thereby providing a greater thickness of metal at those parts.

Instead of forming the lower end or tip of the ribs with the usual projecting knobs, I form the same with a knob, (1 which is cutaway or flattened upon the inner side, as shown at d in Figs. 7 and 8, so that the rib will lie closer to the stick when the umbrella is closed than heretofore.

Heretofore umbrella ribs and stretchers have been formed with broadened fiat-eyed ends fitting broad notches in the crown-piece and runner, and confined in place by wires, but such is not broadly claimed by me.

What I claim is 1. The longitudinally-flanged umbrellarib herein described, having an eyed end formed of the same width as the rib, and the ends of the side flanges of the rib turned or folded inward toward each other beneath the broadened eyed end, substantially as and for the purpose described.

2. A longitudinally-flanged stretcher for the ribs of umbrellas, having an eyed end formed of the. same width as the stretcher, and the end portions of the flange of the stretcher turned or folded inward toward each other beneath the eyed end, substantially as described.
