METALLIC FASTENING FOR UMBRELLA-COVERS.

SPECIFICATION forming part of Letters Patent No. 490,999, dated January 31, 1893.

Application filed May 12, 1892. Serial No. 432,752. (No model.)

To all whom it may concern.-

Be it known thatI, FREDRIK S. UCHERMANN, a subject of the King of Norway and Sweden, residing at Christiansand, in Norway, have invented certain new and useful Improvements in Metallic Fastenings for Umbrellas; and I do hereby declare that the following is a full, clear, andexact description of the in vention, which will enable others skilled in theart to which it appertains to make and use the same, reference beinghad to the accompanying drawings, which form a part of this specification.

My invention relates to improvements in means for securing the covers of umbrellas and parasols to the outer ends or tips of the ribs. The usual method of securing the covers to the tips is by sewing or Wrapping the same with thread, a hole or aperture being formed in the rib near the outer end through which the thread is passed to prevent it from slipping. This is a very insecure method of fastening as the thread is extremely liable to break and the cover become detached from the rib.

The object of my invention is to provide improved metallic fastening devices whereby the employment of thread is obviated and the cover attached to the ribs in a very secure and permanent manner.

The invention consists in the novel construction and combination of parts hereinafter fully described and claimed.

In the accompanying drawings: Figure 1 is a View of a portion of an umbrella cover and rib, connected together according to my invention; Fig. 2 is a view of the clamp detached, on a large scale. Fig. 3 is a view of the ring or loop engaging with the rib and clamping or securing plate; Fig. 4 shows the manner of forming the eye or loop in the ribs.

In the said drawings the reference numeral 1, denotes an umbrella or parasol rib provided with an eye or aperture 2. This eye is formed by bifurcating the end of the rib and twisting said ends together as shown in Fig. 5. The numeral 3 designates a clamp consisting of a piece of sheet metal, having its sides beveled from each end toward the center and bent over upon itself forming two clamping plates 3 and 3 and a loop 3 one of said plates being provided with two or more tongues 4, and with a series of teeth or serrations 5. The numeral 6 denotes aring or loop formed of wire which is adapted to be passed through the eye in the rib, and the loop 3.

Theinethod or manner of securing the cover to the ribs is as follows: The umbrella or parasol may be of any ordinary construction, the gores comprising the cover being sewed together as usual, wit-h the seams running along the ribs. The edge of the cover is inserted between the clamping plates 3 and 3 which are then pressed firmly together by a pair of nippers or pliers, so as to press the teeth 5 into the cloth. The arms are then bent over the opposite plate so as to securely clamp the plates together; The ring 6 is then inserted in the eye in the rib and in the loop 3 and its ends pressed together,-whereby the clamp is securely attached to the rib.

From the above it will be seen that a very simple, inexpensive and efficient fastening device is provided by which the cover can be easily and readily secured to the rib points.

Having thus described my invention, what I claim is:

In an umbrella or parasol, the combination with the cover, and the ribs having their outer ends bifurcated and twisted together forming eyes, of the clamp consisting of a piece of metal bent over upon itself forming clamping 7 plates and a loop, and provided with teeth and overlapping tongues, and the rings engaging with said loops and the eyes in the ribs, substantially as described. v

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

FREDRIK S. UOl-IERMANN.

O. RIELZERR, A. A. CHRISTEMIN.
