  1. 1
    Having now described the construction of the device its operation will be given:— Assuming that the ribs and stretchers are in HO position shown to be the right in Fig. 1 and it is ,desired to fold the device the outer rib sections are first moved upwardly against tlie action of the springs 30 and 31, to positions at, substantially right angles to’ (he 115 inner rib sections, as clearly shown on the right of Fig. 3. When the. parts are so positioned the runner is moved upwardly on the stick sections and beyond the latch 17 and to a point adjacent to the grooved collar 120 12. 'W-hen the.parts are in.these positions the outer sections 18 are moved inwardly and parallel with the inner sections. 13. It. will be, observed, by reference to Fig. 3, at the beginning of .the folding movement, that, 125 is when the outer sections IS are bent at right angles to the inner sections 13. that end of the. coupling plate in engagement with the outer ends of the inner rib sections 13 will be moved outwardly from the said 130 874,643 Ο rib sections and the springs 30 and 31 will· extend in a plane oblique to the length of the coupling plate, as clearly shown in Fig. 3. Thus it will be seen when the outer sec5 tions are moved parallel with the inner sections as before described the distance between the lugs 28 and 29 to which the terminals of the springs are secured, will be decreased whereupon the tension of the 10 springs will be reduced and since the lugs on both clips will now be in a common plane and it being understood that the springs will be sufficiently tensioned to hold the outer rib sections against outward move15 inent it will be evident that the ribs will be yieldingly held in folded position. When it is desired to open the parts from the position shown in Fig. 2 to that shown in Figs. 1 and 3 the runner is moved downwardly 20 to the lowest point on. the stick section 5 after which the outer , rib sections may be moved downwardly and in axial alinement with the inner rib-sections. It will be observed when the rib sections are unfolded, •5 and the springs 30 and 31 tensioned as be;fore described the frame may be raised and . lowered in the ordinary manner without . danger of the rib sections folding. I From the foregoing it can be seen that I 8 have provided a device which is comparai tively simple in structure and inexpensive in manufacture, and which may be applied to most forms of umbrellas now in use with! out necessitating any expensive alterations 5 in the same. I claim:— 1. In a folding umbrella, an oblong coupling plate provided on one side and adjacent to its opposite ends with lugs, a rib section provided at one end with a channeled 40 clip to receive one of said lugs, and a pivot pin passing through the said clip and lug, a second rib section forming a continuation of the first-named rib section, said second rib section having at one end thereof a chan- 45 neled clip similar to the first-named clip and pivotally connected to the other of said lugs, laterally disposed lugs arranged on said clips and located to one side of the pivotal connection between said clips and coupling 50 plate, and a spring having its opposite terminals secured to said lugs, for the purpose described.
  2. 2
    In a folding umbrella, an oblong coupling plate provided on one side and adj a- 55 cent to its opposite ends with lugs, a rib section provided at one end with a channeled clip to receive one of said lugs, and a pivot pin passing through said clip and lug, a second rib section forming a continuation of 60 the first-named rib section, said second rib section having at one end thereof a channeled clip similar to the first-named clip and pivotally connected to the other of said lugs, laterally disposed lugs arranged on said clips 65 and located to one side of the pivotal connection between said clips and coupling plate, a spring having its opposite terminals secured to said lugs, and stops arranged on said coupling plate and beyond said lugs to limit 70 the pivotal movement of the rib sections. In testimony whereof I affix my signature in presence of two witnesses. GUST. CARLSON. Witnesses:Ed. H. Anderson, Oscar J. Eckberg.
