JOHN BRADBURY, OF DEEPEAR, NEAR SHEFFIELD, ENGLAND, ASSIGNOR TO SAMUEL FOX AND COMPANY, LIMITED, 01 STOCKBRIDGE WORKS, NEAR SHEFFIELD, ENG- LAND.

FRAME OF UMBRELLAS AND THE LIKE.

To all whom it may concern:

Be it known that I, JOHN BRADBURY, a subject of the King of Great Britain, residing at 77 Haywoods Park, Deepear, near Sheffield, in the county of York, England, have invented new and useful Improvements in the Frames of Umbrellas and the Like, of which the following is a specification.

In an umbrella or sunshade frame, the ribs of which have tip ends of the ordinary kind, the india-rubber ring which is used to embrace the tips is frequently apt to slip off backward, thus releasing the ribs and therefore failing in the purpose for which it is intended; on the other hand to prevent this slipping off, it is often pushed a considerable way down upon the cover of the closed umbrella, in which case, in addition to being most unsightly, it wears the cover into holes in a short time.

To obviate these disadvantages, I bend or curve the tip end of each rib so that when the several ribs close around the stick, a groove is formed in which the india-rubber ring rests securely, and keeps the ribs firmly in position. The bending or curving may extend over the whole tip end or for a portionof its length only.

In order to form a more pronounced groove I may also raise the back of the rib, which at the same time allows of the opposite edge of the rib that which lies toward the stick being straight. This also brings the loop to which the cover of the umbrella is secured parallel with the other portion of the rib and thus obviates scratching of the stick by the loop.

When necessary I may also hollow out the stick at the point where the tip ends of the ribs come into contact with it the better to accommodate the curved ends described above.

This invention applies to all the different kinds of umbrella or sunshade ribs, whether with loops or solid eyes at the tip ends.

Specification of Letters Patent.

Application filed October 15, 1910.

Patented Aug. 29, 1911. Serial No. 587,143.

The invention is illustrated in the accompanying drawing in which:

Figure 1 shows a side view of the upper part of an umbrella rib of the ordinary kind in which that portion a commonly known as the tip end, is straight. Fig. 2 is a similar view of a rib made in accordance with my invention and shows the tip end bent or curved for the purpose named above. Fig. 3 is a similar view showing the tip end bent or curved, while the back of the rib is raised at the point indicated by (Z. Fig. 4; shows the hollowing out of the stick as indicated at b, the better to accommodate the curved tip ends. Fig. 5 shows the bent or curved tip ends in position when the umbrella is closed, 0 indicating the groove thereby formed to receive a ring of india-rubber e or other suitable material.

The end of each rib is beaded as usual at f and it has means at g, as usual, to receive the thread for attaching the cover to the ribs.

What I claim is:

1. The combination with an umbrella stick of a retaining ring and ribs having means near their outer ends for attaching the cover and which are bent between their extreme outer ends and said attaching means to form a groove which the ring closely fits and whereby the ring is held away from the edges of the cover.

2. The combination with an umbrella stick formed with an annular groove, of a retaining ring and ribs having means near their outer ends for attaching the cover and which are bent between their extreme outer ends and said attaching means to form a groove which the ring closely fits and whereby it is held away from the edges of the cover, the bent ends of said ribs being received in the groove of the stick when the umbrella is closed.

Witnesses: JOHN BRADBURY.
