OLAUS JENSEN, OF SEATTLE, VZASHINGTON.

UMBRELLA.

Application filedFebruary 20, 1928. Serial No. 255,604.

My present invention relates to improvements in umbrellas an d part1 cularly to means for repairing umbrellas. As is well known,

the umbrella ribs forming part'of the frame frequently become broken at the eye part or part that is pivoted to the head of the umbrella, and as a result the umbrella is either worthless, or else the broken rib when used ultimately tears the umbrella cover.

The primary object of my invention is the provision of a repair device which may be applied to the broken end of an umbrella rib in order that the broken rib may again be pivotally joined to thehead of the umbrella. The device is designed in such manner that it may with facility be applied to the end of the broken rib and when located in proper position the repair device renders the rib upon which it is usedas strong as the original structure of the rib.

My invention consists in certain novel combinations and arrangements of parts involv ing the use of a repair sleeve and a lock bar on the sleeve in combination with the broken rib and the head of the umbrella, as will hereinafter be more fullyset forth and claimed.

In the accompanying drawings, I have illustrated one complete example of the physical embodiment of my invention wherein the parts are combined and arranged according to the best mode I have so far devised for the practical application of the principles of my invention.

Figure 1 is a view showing a portion of the head of an umbrella and the pivotal ends of the ribs of the frame, with two repair sleeves or thimbles sh own in use;

Fig. 2 is a sectional detail view showing the use of the repair thimble;

Fig. 3 is an end View showing the repair thimble or sleeve and its locking bar;

Fig. 4: is a perspective view showing the repair sleeve applied to the end of a rib and connected with the retaining ring or wire of the umbrella; V

Fig. 5 is an enlarged transverse sectional view at line 55 of Fig. 1;

Fig. 6 is a perspective view of the lock bar;

' and Fig. 7 is a sectional view showing one of the thimbles or sleeves located on the end of .a broken rib and pivoted to the retaining wire or band of the umbrella head.

In order that the general arrangement and relation of parts may readily be understood, I have shown in Fig. 1 the circular head 1 and tubular stem 2 of an umbrella and the circular head is fashioned with the usual edge notches 3. These edge notches are adapted to receive theusual fi'at eyes 4; of the ribs 5 and the retaining band or "wire 6 passes through the eyesfl to pivotally hold the ribs to the headin usual manner. The ribs 5 are" U-shaped in cross section throughout their length but as usual, are formed ad acent eyes 4; with closed tubular ends as indicated at 5' in Fig. 7.

In carrying out my invention, I utilize a thimble or sleeve 7 which is open at both ends and of a diameter to be slipped over the end of a broken rib. Thus if the eye 4- of the rib is broken, the repair is made by slipping one of these repair sleeves 7 over the broken end of the rib. with a notch 8 and at the sides of the notch are arranged a pair of longitudinally extending prongs 9 as best shown in Fig. 4.

In connection with the sleeve 7, I use a longitudinally extending lock bar 10 which coacts with the sleeve and with the rib for locking the sleeve on the rib. As seen in Fig.

6, one end as 11 of the lock bar is provided with a compound curve and preferably the material is resilient in order that this curved end may act as a spring. The opposite end of the lock bar is provided with an angle bend 12 which terminates in a head 13 and the angular bend is provided with a pair of lateral notches 14- below the head 13 which forms shoulders. Near the spring end 11 of the lock bar a lug 15 is fashioned for coaction with the end of the sleeve and on the opposite side of the lock bar adjacent to the angular end of the lock bar is provided a lug 16 that is designed to coaot with the closed end 5 of the broken rib 5. i

From the above description taken in connection with my drawings, it will be understood that the sleeve is slipped over the end of the broken rib and then the lock bar 10 is inserted through the sleeve so that its spring end 11 frictionally engages the inner face of the rib 5 and the angular end 12 of the lock bar projects partly around the retaining wire 6, as seen in Fig. 7. The notched angular end of the lock bar is slipped into the notch 8 of thesleeve and it will be seen in Figs. 3 andt that the angular end of the lock bar is thus secured to the sleeve. engagement-of the lug 15 with one end of the sleeve and the lug 16 with the closed end of the rib, the repair sleeve is rigidly anchored By the i v 1,684,628" PATENT OFFICE;

On e end of the sleeve is fashioned of the unbroken ribs of the umbrella.

Having thus fully described my invention,

What I claim as new and'de'siretoseeure'by' Letters Patent is 1. A repair sleeve for umbrella ribs having a notched end and spaced prongs thereon, combined with a lock bar adapted to engage saidnotched end, andmeanson the bar for engagement with an umbrella rib and said sleeve respectively. I
