Application filed February 9, 1907. Serial No- 356.506-

To whom it may concern:

. 1 Be it known thatl, Jonn l VoLFn, a citi- Eton oi the United States, resident of loveland, county of Guyahoga and State of Ohio;

have invented a new and useful lrnprove- .ment rnbrella Structures, of the is a specification, the pni-nciple of o the ins ention being herein explained and the The set of this invention, is to provide an uinhreila which may be turned inside -out or reversed, under extraordinary wind pres sure; without iii-joey to the frame or cover" nori'nal openor closed position the sleeve will thereof. f

' My intention, thereioro consists in pro? mdsng an umbrella in which the members composing the'irarne have a fixed normal.

length when the umbrella is open or shut but which are capable of a relative.con-

tract-ion and elongation so as :to permit the tie-to yield and assume, a position of.

least resistance under fibnOlfllfill Wind pres sure.

' ltiylinvention further consists in theiea;

' -turesoi construction and combination of parts as described inthe specification, pointed out in the claims and illustrated in the accoinpanyingdrawings. p

In the accompanying drawings Figure 1 'isflin fits .norm alopen positionand in dotted -other. w I cured to the notch audit-he rib section .4 is

'linesthe-position of the members when the umbrella is reversed. Fig. 2 is an enlarged detail'view, mostly in section, of a portion of the .frameof the umbrella. Fig. 3 is an enlarged detail view showi-n -.a modified constructi'on of the ribs an stretcher rods. i F-ig. t is asection on line 4=1, Fig. 3."

Again referrin to .the drawings .1 repre-. sentsthe umbre la rod'which is preferably made ofLhollow'steel tubing and at the upper endthereof isfrigidly secured a notch 2 to which the ribs are pivotally secured in such a manner-that they are free to swing through an are greater thanhinety degree s. Each ri-b v consisnts of two sections 3 and 4 which are-arranged to telescope with each The rib section3 is .pivotally se provided with azbor'e o arranged to'receive the free end'ofithe section 3; In the wall of cured in the'rib section 3 and is arranged to extend into'the said slot 6 and the arrangement is such that when .therib is extended its normal length the pin is at the end'of the slot 5 nearest to the umbrella rod so that the rib can never be increased or lengthened beyond its normal length and therefore the rib has a hired length when the frame is opened or closed, but can be contracted or shortis arranged a sleeve 10 which is i'ree to slide thereon. The movement of the sleeve '10 on the rib section 4 is linn'tedby two projections orlugs 13 and 14 and the arrangement is such that when the-umbrella frame is in its abut against the lug 13 whichjs nearest the =free end ofthe rib section. -On the umot the usual construction -.and on the rod is anranged the usual spring dog" 16 which holds the runner in its normal position when the umbrella is open but does not prevent the runner from moving up further on the rod under abnormal conditions.

The stretcher rods are formed in tWo secsecured at one end to the runner and in the free end is formeda bore 19 arranged to receive the end of the section 18 and the other end of saidisection 18 is pivotally secured to the sleeve 10 on the rib to which the stretcher rod. is to be attached. In the wall of the 'bore 19 is formed a slot 20 and .a projection into the said slot 20 and the arrangement is such that when the umbrella frame is in its normal open or closed position the projection 21 on the stretcher rod-section 18 will be at the end of .the slot 20,.in the stretcher rod section 1,7,ne-arest 'tothe umbrella rod so that the stretcher rod is free to elongate beyond its no'i-mallength but cannot contract. Within the upper end of the unibrella rod is arranged a coil spring 25' which issecured at its up; er end to a stationary pin 26 and at its 10*. er'end abuts against a -pin 27 which extends through a longitudinal slot formed in the umbrella rod and when the frame of the umbrella is in its normal open positionthe runner will come n contact with said pin and the pressure of the s'pring will tend to hold the runner against the bore 5 :.is formed a'slotfi and a pin 7 is setions 17 and 18. The section 17 ispivotally ened, On the outerend of the rib section brellarod' is slidably arranged a runner '15 21 is arranged on the section 18and extends upward movement. The frame is provided with a suitable cover 30.

In Figs. 3 and i are shown modified construction of a rib and stretcher rod. In this construction the stretcher rod is formed of two telescoping members or sections 3. and 33 and each section formed of a piece of angle iron, one of which is arranged to sl de within the other. .The outer section is pro vided with straps which are arranged to be turned in under the inner member to hold it in position. A lug formed on the section 33 which prevents the stretcher rod from contracting while leaving it free to lengthen. In this construction the rib so is formed in one piece and the stretcher rod is pivotally secured to a lug 37 formed integral with the rib.

It will be understood from the foregoing description that when the umbrella is opened or closed in the normal way there is no move- .ient of the sections of the ribs or of the sections of the stretcher rods on each other, but if. when the" umbrella is open. su'tlicient wind pressure is brought to bear upon the umbrella. then the rib sections will slide in upon each other shortening the 1b., and the stretcher rod sections will slide out upon each'other lengthening the stretcher rod and therefore the whole frame of the umbrella will yield to the wind pressure and be reversed and there will be little liability of it being broken or strained.

I therefore particularly point out and distinctly claim as my invention:

of a rod and a cover supporting frame comprising a notch rigidly mounted at the upper end of said rod, a seriesof ribs pivotally secured to said notch and free to swing through an are greater than ninety degrees, a runner arranged on said rod, stretcher rods pivotall'y secured to said runner and an operative connection arranged between each stretcher rod and the rib to be extended thereby, said connection having the same fixed position on the rib when the umbrella is in its noraml open or closed position and capable of moving on said rib when a pressure is exerted on the inside of said frame tending to reverse said frame.
