FOLDING UMBRELLA.

To allyb ho mit mayc onc em:

Be it known that we, PETER SIMMONS and WiLLIAM J.j FRIoK, fcltizens of the United States, residing at Paterson, in the county ofPassaic and State of New Jersey, have invented. certain. new and useful Improvementsin Folding Umbrellas, of which the following is a specification.

, y This inventionrelates to folding umbrellas, and particularly to folding umbrellas of the class in which the ribs are composed of pivotally connected sections. Instead off arrangin the. outer section of each rib to move pivota lyin the sameradial plane as the inner section,which results at the joint in formin a step, projection or other breech of continuity in the outer or fabric-supporting surface of the rib that reveals itself through the fabric when the umbrella is raised and causes the fabric to wear away at that point, we arrange the outer sectionto move pivotally in another radial plane, that j is, in a plane beside that of the inner section.

Preferably the pivot for the outer section is arranged somewhat short of the free end of the inner section, and the latter has a lateral stop or rest against which the outer section bears when the ribs are extended.

' In the drawing,

Figure 1 is a side elevation of the improved folding umbrella frame, raised Fig. 2 is a side elevation of a fragment-of one of the folding ribs including the joint portion; 9

Fig. 3 is a plan of what is shown in Fig. 2; Figs. 4, 5, 6 and 7 are sectional views on lines 4.4, 5-5, 6-6 and 7-7 of Fig. 3;

i and and lower catches therefor; and e the stretchers.

Each inner rib section f, pivoted to the crown o and formed preferably of channeled material such as is commonly used for umbrella ribs, hassecured to its free end a saddle-piece gthe blank for forming which is illustrated inFig. 8 as having on one side projections g, g and g and on the other side complementary projections g, g and h,

the projection it being somewhat longer than its complement 9 the intermediate projections arepreferably rounded and they have holes 2'. The saddle-piece is attached to the end of the section 7 by bending it on a line between thetwo sets of projections so as to fit over the section and then bending the projections g g onone side and g on the other up into the channelof said section, the projections thus serving to clench the saddle-piece in place. The two intermediate projections are left in a pendent relation, while the projection h is bent laterally and back to form a hook-shaped rest or seat. The holes 2' receive a pin j which site side or edge thereof so as to fit over the section 7 and then bending the projections 70 and the said opposite edge portion 7.2 up into the channel of section f so that they serve to clench the saddle-piece in place. The intermediate projection 70 is bent laterally and back to form a channeled portion whose channel opens oppositely to the channel of the section f. A pin Z penetratesthe saddlepiece and contained portion of section 7",

eing parallel to the pin j.

The outer rib section we is also preferably formed of channeled material the same as the innerrib section f, and it has its inner end flattened, as at n, and fairly snugly received in the channel of saddle-piece is, being pivoted on the pin Z. When the rib is extended, the outer section on thereof obtains support on the seat or rest h, which engagesup in the channel of said section and thus prevents any lateral play, see Fig. 7.

j The opening and closing of the umbrella occur the same as in any ordinary umbrella. But by releasing the upper catch cl the run ner d may be run up to the crown 0, so that the stretchers are grouped around the upper portion of the staff a; (dotted lines, Fig. 1) and the ribs may be collapsed or closed, in

which position their outer sections may now be folded outwardly and back on their upper or inner sections f.

By arranging the outer section so that it is plvotally movable in a plane beside that of the inner section of each rib We produce a' joint between the sections that avoids unduly prominent steps, projections or the like on the fabric-supporting surface of. the rib and also the pinching of the fabric by the rib when the latter is folded.

The coacting means to limit the movement of the outer rib sections past the position Where they Will be alined with the inner rib sections form an interlock (as indicated in Fig. 7, by portion 71. engaging in the-channel of rib section m), that preserves the sections parallel in plan when the ribs are extended.

Having thus fully described our invention, We claim: v o

1. A folding umbrella rib including an inner member and an outer member pivoted on the inner member and pivotally movable in a plane beside that of the inner member, one member having at a point removed from the pivot between said members a lateral hook and the other at a point correspondingly removed from said pivot a channel adapted to receive said hook and coact with the hook to limit the pivotal movement of the outer member.

2. A folding umbrella rib including an outer and an inner section, the outer section being pivotally movable in a plane beside the inner section and one section being channeled, a sheet-metal piece bent around the convex side, and having opposite edge portions thereof bent into the channel, of the channeled section and also having a lateral other section.

In testimony whereof we aflix our signatures.

PETER S. SIMMONS. WILLIAM J. FRIOK.
