Specification of Letters Patent.

Patented June a, 1918.

Application filed December 27, 1917. Serial No. 209,082.

To all whom it may concern Be it known that I, IVAR L. RUDOLPH, a citizen of Sweden, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Umbrellas, of which the following is a specification.

This invention relates to folding umbrellas.

The primary object of the invention is to provide an umbrella which is capable of being readily folded into small compass, so as to enable the same to be conveniently carried in a grip or a suit case. A further object of the invention is to provide an umbrella of this character which can also be folded in regular manner as readily and conveniently as a non-foldable umbrella. A still further object of the invention is to provide a device of this character, which has its fabric supporting elements so assembled and arranged as to minimize the opportunity for breaking or unduly stretch ing the fabric, when the umbrella is raised, whereby the length of service of umbrellas of this character is greatly increased. Still further objects of the invention reside in providing a folding umbrella which shall be of simple and inexpensive construction, which is composed of but few readily assembled parts, which is easy of operation, and which will prove thoroughly efficient in the attainment of the ends for which it is designed.

With these objects in view together with others which will appear as the description proceeds, the invention resides in the novel formation, combination and arrangements of parts, all as will be described more fully hereinafter, illustrated in the drawings, and

particularly pointed out in the claims.

In the drawings:

Figure 1, is a fragmentary sectional view taken through an umbrella embodying the invention, the view illustrating the position the parts will assume when the umbrella is raised.

Fig. 2, is a view similar to Fig. 1 and illustrating the umbrella folded in regular everyday-position.

Fig. 3, is a view showin the position of the parts when the umbre la is folded for packing into small space.

Referrin to the drawings, 6 indicates the umbrel a stalf, which in the present instance comprises an elongated tube open at both ends. This tube may be formed of any suitable material and a tip 17 is detachstaff 6 and has a shoulder 16 to limit the inward movement therein.

The inner extremity of the tip has secured thereto a spring catch 15 for engagement within a notch or slot 1 1 in the stafi 6. The handle is indicated generally at 2 and comprises a stem-portion 29 to the outer end of which is secured a hand grip 1. The stem 29 is also of a size to fit snugly within the tubular stafi' 6, and carries a spring pressed detent 3 adapted to engage within a notch or slot 7 in the staff 6. This detent locks the handle against inward or outward 1novement, but when moved to released position permits of the handle being readily slid inwardly or outwardly of the tubular staff. The inner end of the stem 29 is beveled or tapered as at 5 and when the same is moved inwardly of the staff this beveled end will engage the inclined outer extremity of the spring catch 15 of the tip, so as to withdraw the detent 15 from engagement within the slot 14 in the staif. Further inward movement of the same will operate to eject the tip 17 from the staff, projecting outwardly from the stafi' 6 adjacent thetip end thereof is the circular plate 18. This plate is preferably formed of metal and is bent downwardly and inwardly upon itself at its outer edge in such a manner as to form a lip which extends and forms a lap over the fabric, which is fastened to a ring 21. This ring surrounds the plate in groove formed by plate, immediately under the lap. Plate 18 is then bent outwardly and downwardly and inwardly and upwardly, forming a loop 19 at lower edge. Into this 100 is cut notches to receive the ribs. The ribs comprise inner section 20 and outer section 27. The inner end of section 20 of the rib is pivoted to loop 19 by a ring 30. The outer end of section 20 is pivoted to joint plate 25 which fits snugly in channel of rib. Outer section of rib 27 is fastened in similar manner to joint plate 25. Joint-plate 25 is so constructed as to fit snugly in channels of both rib sections and brace 13, and resting solidly in the bottom of said channels, so as to prevent rib-section 27 to swing inward, and to form a substantial frame when umbrella is raised. On the upper and inner end of joint plate 25 is an extension a sliding sleeve lO at 12.. At the upper end of the sleeve the inside edge is beveled off and thus the hole made a trifle largorin' order to permit sleeve 10 to pass easily over lower end of staff 6 when raising the umbrella from position illustrated in Flg. 2. The spring catch 9 is positioned in'the staff '6 so as to lock the sleeve 10 against sliding back when raised. Said catch 9 is flush on inside of staff 6so as to permit handle 2 to slide through stafi. 6 when folding umbrella as in Fig. 3. Then it is desired to fold the umbrella as shown in Fig. 2, the spring catch 9 is forced inwardly and the sleeve 10 is moved toward handle. This action moves the fabric supporting ribs inwardly to closed position. I

When it is desired to fold the umbrella as shown in Fig. 3 the spring catch 9 is forced inwardly, and the sleeve 10 is moved toward the handle until tension on fabric has ceased, then the outer section 27 of the rib is swung outward andtoward tip 17' describing a circle with pivot 26 as center. When rib section 27 has assumed a square position to joint plate 25, said joint-plate will move with rib section 27 swingin on pivot 24c- When both rib sections have een folded together, with the fabric doubled between them sleeve 10 is pushed toward the tip 17 until ribs 13 rest against staff 6. Spring catch 3 is then forcedinwardly and section 2 of handle ispushed through staff 6. Beveled end of handle 2 engages spring catch 15 on tip 17 releasing same from notch 14: in staff 16. Further pressure on handle 2 will eject tip 17.

derstood that various changes in the minor details of construction, proportion and ar nrangements of parts may be made without departing from the spirit of the invention .as defined in the appended claims.

What I claim is: p

1. In a folding umbrella a hollow upper staff section a detachable tip means for looking the tip to the staff a lower staff section. slidable within the, upper staff section said lower section adapted in collapsing within the upper section to disengage said tip locking means.

2. The device defined in claim l and the lower section is adapted to eject the tip from the upper section.

3. In a folding umbrella an upper hollow staff section a tipdetachably engaged with in said section a catch on the tip to engage said section a lower staff section slidably engaged within the upper section the upper end of the lower section being formed to disengage the catch and eject the tip when the lowersection is collapsed within the upper section. 1

4. In a foldinginnbrella a rib comprising inner and outer sections, each shaped in cross section a joint-plate pivoted within the sides of the rib sections and a brace pivotally connected tothe joint-plate.

In testimony whereof I aiiix my signature in presence of two witnesses.
