Application filed June 2B.

The main object of this invention is to provide an umbrella having all parts of its body collapsible telescoping so that it may be folded into a compact bundle and readily carried in an ordinary pocket.

The above and other objects will become apparent in the description below, in which cha `acters of reference refer to like-named parts in the drawing.

Referring briefly'to the drawing, Figure 1 is a longitudinal elevational vien of the skeleton of the umbrella, showing a half of the roof portion with the cover removed, in partly extended position, and in fully extended position.

Figure 2 is an elevational view, showing the umbrella completely collapsed.

Figure 3 is a longitudinal sectional elevational view of a portion of the rib sections.

Referring' in detail to the drawing, the numeral 10 indicates the tubular handle of the umbrella. This handle is hollow thruout its length and telescopingly receives a section tube 11 which in turn receives a third The upper ends of these tubular sections are open and are provided with internally threaded portions. The lower ends of the sections 11 and 12 are also open and are provided with threaded external surfaces which engage the internally threaded surfaces of the tube members. The upper or third tube slidably receives a rod 13 which has a flanged head inserted in the chamber of the tube 12 and at its upper end is provided with an additional llange 14 to which hollow flexible ribs 15 are pivotally attached. The channel formed in these hollow ribs 15 receives stays 1G which have very small knobs 17 at one end, which latter are pivoted in the hollowr ribs and are adapted to prevent the latter from telescoping inadvertently into said ribs. Said ribs extend radially from the flanges and project in curved conformation when a shed of fabric is spread over these-ribs and secured to the outer end of the stays 16. Each one of these hollow ribs has a sleeve 18 slidabb.Y mounted thereon. These sleeves are slitted longitudinally thruout their length in order to produce flexibility so that the same can be spread or opened when passing over the knobs 17. Similar knobs are provided Within the channel of the hollow ribs 15 which engage the surface of members 16 frictionally and are adapted to keep the ribs in a position extended from the hollow ribs reet. serial no. lirez-la.

l5, which latter are also seamed longitudiv nally. Said sleeves have ear extensions formed thereon which receive pivot pins for securing one end of hollow supporting ribs 19 thereto. rhe hollow supporting ribs slidably receive rods 2() whose lower ends are pivoted to a flanged collar 21, the flanged collar being slidable upon the articulated staff of the umbrella. A pin 22 passes diametrically thru the tube 12 near its upper end and is adapted to support the collar 21 when the latter is in raised position and secure from sliding upwardly by seating on the ridge 23.

The umbrella is adapted to be complete? ly telescoped and collapsed so that it can be conveniently carried in the pocket. The staff of the umbrella, consisting of parts 10,

11, 12, and 13, which are slidable one into .the other, are each provided with threaded internal and external ends. The part 1-0 being threaded only internally at its upper end normally engages the threaded external lower end of section 11 and the upper internally threaded end of said section engages the external threaded end of the third section 12. When these threaded portions are disengaged from each other, all of the sections 11, 12, and 13, telescope directly into the handle 10, as indicated in Figure 2. By

detaching the fabric shed, not shown on the drawing, from the stays 16, the latter may be slid into the hollow ribs 15, which it is to be noted are made of seamed material so that they may be slightly spread. These stays 16 are locked in position by the knobs contained in the channel of the hollow tubes 15. After that, the pin 22 is removed from its opening in the tube 12 and the entire roof skeleton of the umbrella may be conveniently folded and collapsed into the position illustrated in Figure 2.

It is to be notedf that certain changes in form and construction may be made without departing from the spirit and scope of the invention.

In an umbrella, a plurality of tubular sections slidab-le endwise one into the other, threaded portions on each of said sections for locking the same in extended position, said sections forming a staff, the sections being successively telescoped one into the adjacent one, a rod slidable in the uppermost tubular section having an external thread at its lower end engaging the internal thread at the upper end of the uppermost hollow section, telescoping ribs pivoted to said rod, said ribs comprising Va hollow rib member joined to said rod, a rod member slidable in said rib, support ribs slidably connected to said hollow ribs, knobs on the hollow ribs externally and internally, Said hollow ribs being seemed thruout their length, sleeves slitted lengthwise slidable on saidL hollow ribs, a collar slidable on said tubular sections and pivotally connected to the telescoping,` support ribs, and t pin in one of said sections and supporting said collar when the umbrella is in extended position.

In testimony whereof I aix my signature.

ALEXANDER MOSER.
