invention relates to umbrellas and more particularly to. umbrellas adapted tocollapse so thatthey maybe conveniently carried when not in use.

While traveling, it is often desirable to includean umbrella in the equipage, but on account of the awkward shape of the usual umbrella, it is inconvenient to do so.

It is therefore an object of this invention to provide an umbrella which may be collapsed so that it will occupy an inappreciable space when not in use.

It is a further object of the. invention to provide a collapsible umbrella which may be readily placed in condition for use.

These and other objects are attained by the novel construction,combination and arrangement of parts,l1ereinafter described and shown in the accompanying drawings, constituting a material part of this disclosure, and in which Figure 1 is a perspective view showing a collapsed umbrella positioned in a bag. 1 .Figure 2is a longitudinal sectional view of the umbrella.

, Figure 3 is a cross-sectional view of the upper section of the umbrella when in use.

'Figure 4 is a view taken on line 4-4 of Figure 3. 30

Figure 5. is a sectional view similar to Figure 3 showing the upper section of the umbrella when in a collapsed condition.

Figure 6 is a sectional view similar to Figure 2, showing one of the collapsibleribs used in the umbrella.

Figure 7 is a plan view of a joint used in the ribs. I I

, Figure 8 is a sectional View of the handle of the umbrella, showing actuating mechanism contained therein.

Figure 9 is an enlarged view of a winding drum included in the actuating mechanism.

Referring to Figure'2, the center post of the umbrella is collapsible and comprises a plurality of telescoping sections 10, 11, 12 and 13, each section having a pin 14 adapted to be moved in angular slot 15 in an adjacent section to hold them in an extended position. To facilitate the manipulation of the pin and slot connection between the sections, each is provided with a flange 16 interlocking with a similarflange 17 on the adjacent section.

Thelower section 10 has agrooved portion 18 and a clown-turned flange 19. A sheet metal handle 20 is held in the groove 18 and the lower part 20 of the handle is rotatable on the upper part 20. J ournalled in flange 19 is a shaft 21 to which are fixed a pair of drums 22 having elastic cords 23 wound around them. Fixed to the lower part 20 of the handle is a stud 24 upon which is mounted a rack 25 in engagement with pinions 26 fixed to shaft 21. A bracket 27 carried by the upper handle part 20 has pivoted thereon a pawl 28, which is normally held in engagement with one of the pinions 26 by the spring 29am adapted to be disengaged from the pinion by a plunger 30 slidablymountecl in member 20. (See Figure 8.)

The elastic cords23 pass up through the telescoping sections and is also wound about the drum 31 journalled in section 13. Also wound about drum 31 is afwire 32 which is connected to wires 33, the latter being con- :nected to the'ribs of the umbrella, there being I awire 33, for each rib.

' l/Vire33 passes through an aperture in the inwardly projectingarm 34 of a rib which is pivoted at 36 and the wire is guided through the hollow rib by eyes and passes through section 37 of the rib, the section 31 being connectedto section 4.0 by a joint 38. A spring 39 fixed to the joint and bearing against section. 40, tends to move the latter counterclockwise into a position against section 37.

pushed in position by the engagement of the hook on the end of leaf spring 46 in the notch The spring 46 is fixed to section 13 at 47 and a small plunger 48 passing through an aperture in the section 13 is adapted to engage centerpost consisting of a plurality of'telesin the pushed in position.

anend of the spring to disengage the latter from the notch 45'. When in a pushed in position, the lower end of the block 45 engages Y to each other as shownin Figure 2, and the lower handle part is rotated to cause the rack to rotate the pinions 26, the plunger being depressed todisengage the pawl 28 'from'the pinions. Rotationof the pinions cause shaft 21 to be rotated to wind cords 23 about the drums 22 and cause drum 31 to rotate to wind wire32 thereon, thus pulling oniwires 33 and straightening out the hollow ribs against the action of the springs 39 and 42, When the ribs have been straightened 0ut,'the block is pushed'in so that its lower surface'bears-against the arms 3st, to hold the latter in a horizontal position, and the spring latch 46 snaps into notch 45 to holdthe block The umbrella "is now incondition for use.

When it is desired'to collapse the umbrella,

jplunge'rs 48 are depressed to release the block 45,-and the ribs automatically collapse. The telescoping sections are then placed one fixed to the rib, a drum upon which the other end of the wire may be wound, said drum being journalled in one of thetelescoping sec; tions, a handle fixedto thecenter post, and

passing through the rib and having one end 7 r rack and pinion means carried by thehandle to wind the cord on the drum, whereby the rib assumes a substantially horizontal position. l In witness whereof I have affixed my signature. I I v v ,e
