FREDERICK SCHILLIN G, OF NEWARK, NEW JERSEY.

FOLDABLE UIVIIBRELLA.

Application filed June 2D, 1916.

To all whom. it may concern.'

Be it known that l, FREDERICK SGHILLING, a citizen of the United States, and a resident of Newark, county of Essex, and State of New Jersey, have invented a certain new and useful Improvement in Foldable Umbrellas, of which the following is a full, clear, and exact specification. y

rlhis invention relates more particularly to a class of umbrellas, and has for its object primarily to provide a form of umbrella adapted when not in use to be folded into a compact parcel for occupying a limited space so as to be readily carried in a hand satchel, or trunk or otherwise for convenient use when traveling. This is accomplished mainly by providing a rod, and to the rod is pivote-d one of the corresponding ends of a number of ribs for being swung radially to and from the rod. Each lof the pivoted ribs has a section which is slidably adjustable thereon whereby the ribs may be reduced and increased in length, and on the rod is a movable sleeve to which is pivoted one of the corresponding ends of a plurality of stays each having its other end pivotally held to the adjustable section of each of Athe ribs so that when the umbrella is closed the sleeve and the stays may be moved Jfor guiding the adjustable sections of the ribs to reduce the lengths of the ribs.

Other objects of the invention are to provide retaining elements for releasably holding the adjustable sections of the ribs with the stays against accidental movement when the sections are extensibly adjusted on the pivoted sections of the ribs; to provide forms of the rod which may be composed of detachably connected sections so as to be collapsible when the umbrella is not in use;

and to provide a ring adapted to be removably guided over the stays when closed on the rod tor allowing the stays with the sleeveto be moved for slidably adjusting the adjustable sections of the ribs on the f pivoted sections.-

A practical embodiment of the invention is represented in the accompanying drawing forming a part of this specication in which similar characters of reference indicate corresponding parts in all the views, the said invention being more fully described hereinafter, and then pointed out in the claims at the end of. the description.

Fig. 2 is an enlarged inverted plan, partly broken away, of one of the extensible ribs used in the umbrella.

Fig, 3 is an enlarged fragmentary view, partly in section and partly in detail, taken on the line 111-111 of Fig. 1, and

Fig. L1 is a view showing the ribs of the umbrella when folded as well as showing the parts of the rod of the umbrella when separated. f

rhe umbrella has a rod 10 which may be of a collapsible Jrorm composed of a main section 11, an end section 12, and a handle section 13, and these sections ofthe rod may be detachably connected in any suitable manner, though I prefer to provide the sections in the forms of metal tubes. In the main tubular section 11 of the rod 10 is a core, or bar 14 cfa length'so that both of its ends extend some distance beyond the ends ot' this tubular section, and these protruding ends are threaded, as at 15 and 16. The bar 11 is of less diameter than the tubular section 11', and this bar is rigidly held cen- .trally of the tubular section by one, or more pins 17 being driven through the vtubular section and through the bar to provide a In the end section 12 of the rod tion, and this tube is tightly-held in the end Y section by a pin 20 passed'through the openings in the tube and in theend section. The

j protruding end of the tube19 is of a diam- Aeter to removably fit in the space 18 between tlie bar 141 and the main section 11, and this protruding end of the tube-is interiorly threaded 'for allowing the threaded end 16 of the bar 11 to be screwed therein for detachably connecting thel end section 12 to the main section 11.l In the end yof the Vhandle section 13 is a tube 21 with one of its ends protruding out of the handle section, and this tubefis secured in the handie section by means of a pin 22 driven through openings in the handle section and in the tube. The tube 21 is of a diameter so as to removably it in the space 18 between the bar 14 and the main section 11. and the interior of the protruding end ot the tube 21 is threaded, as shown` to permit the threaded end 16 of the bar to be screwed.

therein for also removably fastening the handle section to the main section. Instead of employing this torni of collapsible rod, 1 may use a rigid rod it desired.

At the end ot the main section 11 oit the rod adjacent to the end section 12 is a stationary ring 23 ol: the usual type having radially extending spaced lugs, and on this main sect-ion contiguous to the ring is a spring catch. or stop, as 2l, which may be or a form used in ordinary umbrellas. ln 0o the spaces between the lugs of the ring are pivoted One ol the corresponding ends of a number ot ribs, as 2*', all ol2 which are preferably similar in formations. Each ot' the ribs 25 is of a tubular form as well as being somewhat similar to the length ot' the main section 11 of the rod 10, and all of these ribs are arranged so as to be swung radially to and from the rod. In the underside of the tubular section of each of the ribs 25, and disposed lengthwise thereof, is a slot 26 extending from the pivoted end of the rib to nearly its opposite free end. Part of the slot 26 of each of the ribs is reduced in width, as at 27, by torining the adjacent portions of the wall of the rib accordingly. 1n the slotted tubular section oli each of the ribs is a slidable section 2S preferably in the form ot' a rod and by each rib being made in this manner all of the ribs are adapted to be increased and reduced in lengths by the rods being movable inwardly and outwardly oi. the tree ends of the tubular sections. Connected to the slidable section 28 of each rib as well as being fastened on the rod 10 above the ring 23 is a cover 30. rEhe cover 30 is thereby` arranged on top of the ribs.

On the rod 10 is a slide, or sleeve 29 which may be ot a well known, or any preferred type adapted to be moved baclr and forth on the rod, and this slide has a slot, or opening 30 for recept-ion of the spring stop 24 when the slide is moved accordingly on the rod and this slide has outwardly extending spaced lugs 31. 1n the spaces between the lugs of the slide 29 are pivoted one of the corresponding ends of a number of stays 32 which are of similar numbers to the ribs. and serving to releasably hold the slidable sections 2S against accidental movement in the tubular sections 'of the ribs, 1 provide a plurality of retaining elements. as 3?), all of whicli mav be ot' similar formations. y

Each of the retaining elements 33 is preferably made of spring metal bent in substantially a` U-shape to provide two spaced arms 311- and and through these arms contiguous to their free ends are registered slots 36 and S7. rllhe connected end of the slotted. arms 3l and of each of the retaining elements B3 is soldered, or otl'ierwise secured to the end of each of the slidable sections et' the ribs which are disposed in the tubular sectiong thereof, while between the arms of each ot' the retaining elements is pivoted the second end of each of the stays 32 by means ot a pin which is movably disposed through the slots of the arms o'f its respective retaining element. The spring arms S1 and of each of the retaining' elements are spaced apart at a distance to move freely in the slots 2G ot' the tubular sections of the ribs as well as being spaced apart at a distance so that when the retaining elements are guided into the reduced end portions 27 of the slots the tension ot' the arms will cause them to trictionally engage the edge of the reduced portions of the slots, and the slidable sections or' the ribs will then be releasably held in the tubular sections thereof against accidental displacement when the slidable sections are eXtensibly adjusted in the tubular sections.

1n practice the umbrella is opened for use by moving the slide 29 on the rod 10 toward the end section 12 of the rod so that the spring stop 21 will be seated in the slot 30 oit the slide. The stays 32 will then be guided radially outward from the rod, and the slidable sections 28 of the ribs will be moved also outwardly of the tubular sections 25, simultaneously with the radial movement of the ribs in the manner common to the raising of umbrellas of the usual types. Then the stays 32 have been swung sullicient distances the retaining elements 33 will be admitted into the reduced end portions 27 of the slots 26 for releasably holding the sections 25 of the ribs against accidental movement, as above explained, and to fold the umbrella so as to be carried in a hand satchel, or trunk, or otherwise for convenient transportation, the slide 29 is released from its engagement with the stop 2-l by springing the stop from its engagement in the opening of the slide 29. The slide is then reversely guided on the rod toward the handle section 13, and the stays with the ribs will thereby be reversely swung to closed positions on the rod. To permit the umbrella to be folded, or reduced in length, a ring, as 36, or other suitable means is guided over the ribs 25, and the sleeve, or slide 29 with the stays are forced toward the top, or end section 12 of the rod 10. T he sections 28 of the ribs will thereby be slidably adjusted inward of the tubular sections 25, and the cover 30 will be partially intolded between the tubular sections 25 of the ribs and the stays 32. The end section 12 of the rodA 10 may then be disconnected from the main section 11 by unscrewing the tube 19 from the bar 1-1, and the handle section 13 may also be detached from the main section ot the rod by unscrewing the tube 21 also from the bar 14;

oit the main section or the rod, 1n this inanner a simple and eflicient umbrella may be provided for being packed into a very limited space When not in use.

In the foregoing description, I have cmbodied the preferred form of my invention, but I do not Wish to be understood as limit; ing myselii thereto, as I am awa-re that modilications may be made therein Without departing' from the principle, or sacrificing any oi" the advantages of this invention, therefore I reserve to niyselil the right to make such changes as fairly tall Within the scope thereof.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:-

'Qhe combination, in a 'foldable umbrella, a rod composed of detachable sections, a plurality of ribs each having one end pivoted to the rod Jfor being swung toward and :trom the rod, and each of the ribs having a slotted tubular section with a slidably adjustable rod in the tubular section of its respective rib Where-by the ribs may be reduced and increased in length, a Sleeve on the sectional rod, a. plurality of stays each having one end pivoted to the sleeve, a plurality of yielding retaining elements one pivotally connecting the second end of each stay to the slidable rod of each of the ribs, and the retaining elements being adapted 'to rictionally engage the tubular sections of the ribs to hold the adjustable rod against accidental movement when eXtensibly adjusted in the pivoted sections.

This specieation signed and witnessed this 17th day of June A. D. 1916.

FREDERICK SCHILLING.
