JOSEPH MACKERT, OF SEATTLE, WASHINGTON.

UMBRELLA.

To all whom it may concern Be it known that I, JOSEPH MACKERT, citizen of the United States, residing at Seattle, in the county of King and State of WVashington, have invented a certain new and useful Improvement in Umbrellas, of which the following is a specification. My invention relates to improvements in umbrellas and its object is to provide a cheap, strong, and simply constructed umi brella that may be turned inside out without sustaining injury.

Numerous umbrellas of the ordinary type are broken by being caught by the wind and turned inside out and it is my purpose to eliminate this trouble by providing an umbrella that has its ribs so hinged that the umbrella may be turned inside out and again brought back to its normal position Without injuring any of its parts. I attain this object by devices illustrated in the accompanying drawings, wherein Figure 1 is a vertical sectional view of an umbrella embodying my invention in its normal raised position, Fig. 2 is a vertical sectional view of a similar umbrella as it appears when it is turned inside out, Fig. 3 is an enlarged view of the rib joint embodied in my invention when the rib is in its extended position, Fig. 4. is an enlarged r b joint as it appears when the umbrella is turned inside out and Fig. 5 is an enlarged sectional view on the line 00, x of Fig. 3.

Like reference numerals indicate like parts throughout the drawings.

Referring to the drawings, 6 is a fixed sleeve of the usual type positioned near the upper end of an umbrella rod 7 and having radiating arms or lugs between which are pivotally mounted the upper ends of a plurality of radiating ribs, each rib consists of two parts, an upper rib 8, 8 and a lower rib 9, 9 which are pivotally connected by two link 10 and 11 respectively. The lower end of the rib 8 is provided with a guide collar 12 adapted to slide over the rib 9 and normally adapted to seat within the notch 13 on the bottom side of the rib 9. The lower end of the rib 8 is also provided with a spring 14 which projects beyond the end of said rib and is adapted to bear on the top side of the rib 9 and normally to seat within the notch 15. The sleeve 16 having a plurality of radiating arms or lugs 23 between which are pivotally mounted the lower ends of a plurality of brace ribs 17 is slidably Specification of Letters Patent.

Serial No. 763,033.

mounted on the umbrella rod 7 in the usual manner, the upper ends of the brace ribs 17 being pivotally connected to the lower main rib 9. The link 10 has its one end pivotally attached to a stud 18 on the upper rib 8 and its other end pivotally attached to one end of the link 11, the other end of the link 11 being pivotally attached to the upper end of the lower rib 9. A pin 19 which projects from either side of the link 10 is adapted to engage an offset 20 provided on its upper end of the link 11 and thus prevent the links 10 and 11 from folding backward on each other. The upper end of the rib 9 terminates in a hook-shaped member 21 which is normally adapted to have its end positioned be tween the two sides of the link 10 and to have its point rest upon the bottom of said link 10, as illustrated in Fig. 5, thus serving as a stop and guide and greatly strengthening the pivotal structure.

My umbrella when in the normal raised or lowered position conforms substantially to the ordinary type of umbrella and opens and closes in the usual manner, but when it is caught by the wind and turned inside out the pivoted links 10 and 11 are thrown outward and backward as illustrated in Fig. 2, thus allowing the ribs to be turned backward toward the umbrella tip without injuring any of their parts. WVhen the umbrella is turned inside out it may be lowered by lowering the sleeve 16 and each rib may be restored to its normal extended position by exerting a slight pull on its lower end. l/Vhen in its normal position the spring 1 1 rests within the notch 15 and the collar 12 rests within the notch 13 thus preventing the umbrella from turning inside out or the rib joints from becoming operative when the umbrella is being raised or lowered in common use, but when a force sufficiently strong to turn the umbrella inside out is exerted the spring 1 1 and the collar 12 are moved from the notches 15 and 13 respectively and allow the rib joints to become operative thus preventing the ribs from being broken.

Obviously minor changes in the details of construction of my umbrella may be made within the scope of the appended claims without departing from the spirit of my invention or sacrificing any of its advantages.

What I claim is:

1. In an umbrella of the class described, the combination with an umbrella stick, of a plurality of radiating ribs each of which comprises an inner and an outer member each inner member of said ribs having one end articulated with said umbrella stick, a double link joint pivotally connecting the other end of said inner member and the inner end of said outer member, detent means provided on the outer end of said inner member to allow said outer member to swing in one direction only, and a spring associated with the inner endof said outer member normally to prevent said outer member from swinging in said direction.

2. In an umbrella of the class described, the combination with a plurality of ribs each of which comprises two members, of a double joint articulating one member with its mate and permitting one of such members to swing in one direction'only with respect to the other of said members, whereby one In witness whereof, I hereunto subscribe my name this twentyefourth day of'March A. D. 1913.
