' TELESCOPING UMBRELLA.

Applicationjiled February 2, 1923. Serial No. 616,558.

This invention relates to telescoping umbrellas and proposes the construction of an umbrella in which the fabric cover is stretched over and attached to telescopic ribs supported by a telescopic staff, the whole being contained, when-closed, within a handle which may or may not be telescopic according to modified forms'of the invention.

One of the objects of the invention is the provision'of an umbrellathat may be carried in an ordinary novelty -bag,thatis compact and-of pleasing appearance when closed, that maybe easily and quickly Opened and that 'is thoroughly reliable both in operation and 1 Another object of the invention isjthe provision of a telescopic umbrella, contained when closed within a telescopic handle,-the latter being extensible toitsmaximum capacity, through the closing movement of the umbrella and functioning as a casing therefor, and automatically telescoping to its minimum length, to serve merely as ahandle when the umbrella is open.

Another object of the invention is the'construction of an umbrella having collapsible sectional ribs and a telescopic sectional stall, saidribs and staff beingv arranged to be brought into parallelism by a closing movement of the umbrella and simultaneously shortened by pressure in a direction axially of the staff, causing the sections of said staff and ribs to slide relatively over one another into a casing secured to the lower end of the staff, further pressure in an axial direction ausingthe lower end of the staff to co-act with the end of said casing extendingtlie sec-- tions thereof to increase the capacity of said casing sufliciently to embrace the umbrella.

Still another object of the invention is the provision of-novel means for automatically locking the ribs against collapse when fully extended and for permitting them to telescope when a predetermined stage of the closing movement of the umbrella has been reached.

Afurther object of the invention is the provision of a telescopic stail with relatively fixed rib attaching ferrule and a slidable rib engaging runner mounted thereupon, and means associated with said staff for retaini ng the runner in the open or closed position of the umbrella, said means being selectively rendered operative, or released, by a part movable with and relatively to said sliding runner through pressure applied axially to said part in the act of opening or closing the umbrella.

Another object of the invention is the provision of a hollowstalf provided with resilient latching members secured therein and normally projecting therefrom, said resilient latching members being formedwith portions contacting the opposite wall from that to which said stop members are secured, and a reciprocable key'for depressing certain ofsaid latching members provided with a longitudinal slot embracing said contacting portions and affording themlateral'support throughout the range of. movement of said key. F

A still further object of theinvention resides in the provision of suitable locks for holding or releasing the staif when in its outermost positionrelative to the handle, and for locking the section'sv offthe handle casing in collapsed position, said locking means functioning automatically when" the umbrella is spread or closed; a 4

With the above and other objects in view, my invention consists in the improved telescoping umbrella illustrated in the accompanying drawings, described in the following specification, and particularly claimed,

-. 1 Referring now in detail to. the several figures, the numerals 1 and2 represent respectively 1 the telescopic sections of the case, forming thehandlel of th'e.umbrella,-3. and 4 designating the-telescoping sections of the staff. These parts will-be described in great-v er: detail; as the. specification .develops. To the upper-cendzof-the stafl' section ithe rib. attaching iferrlule 5; is secured; by means of the rivet-6 which passes through aligned apertures in said'ierrule and staff section. This ferrule is of the construction usually found in umbrellas, comprising'a flange furnished with ay'plurality .of radial notches 7 equal in number to the number of ribs of the umbrella anda circumferential groove 8 intersecting-the ends of said: notches. The ends of the ribs 'of the umbrella are arranged in the 'radial slots and secured-in place by a w'ire'91passing through apertures in said ends and seated in the circumferential groove.

Each of the ribs consists of a pair of 00-. operating and telescoping sectionslO and 11. The shape of thesection 10 is best. shown; in Figure 11, it being. formed of anovally bent metallic strip provided on its lower side with a longitudinal slot 12. A reinforcing piece 13 of similar shape to thatof-the rib section 10-but sufliciently smallto enter the latter, is inserted in the outer endthereof, the under side of said reinforcing piece be ing formed with a cut-away portion 14 having end walls 15- and 16,. The upper end of the reinforcing piece 13 is internally beveled as shown at 17 in. Figure 10 to ensure smoothness-0f operation. v

The rib section 11 takes the form of arod having the shape shown in Figure 11. comprising bead 18 of a shape and size to smoothly 'slide within the bore of the rib section 10. having'a web 19, slidable longitudinally in theslot 12 in the upper rib section, and arranged with a curve flange 29 adapted to slidably engage the outer surface of said ribsectionadjacent the sidesof the slot 12. These-parts areshown in extended position in Figure 1, and when the umbrella BEST AVAILABLE COPY "til the upperend thereof assumes a position adjacent the rib attaching ferrule 5, the effective length of the umbrella rib thus b reduced substantially one-half.

A flexible fabric cover, indicated in Fig. 1 b .-'-;-dot and dash lines, and in Fig. 2 in :folded condition as indicated by the referencecharacter 118, of usual construction adapted to be supported by the ribs of the umbrella and extends'ovcr the ferrule 5, a leather washer 21- interyening between said ferrule andgthe fabric cover for the protection ot' thelatter. A metal washer 2'3 resides. upon the fabric cover above the washer 21 and the upper end of the staff sectionyt extends through said washer-a slight H d sta c e, ext nd ng en being le gi udina y p it-at a umber a P aces for n lugs-.23. W C i-Iare turned down over the washer 22 holding the latter and thefabric e -c amped agai t-th r a a hing f rule 5. Theribisection 1Q isprovided with a loop 24 to whiclrthe fabric co rer is sccured and the rib section 11 is formed with an aperture 25 and a ring 26 towhich also the cover is attached. Thering .26 is split,

the ends thereof resting- .in the grooves formed ontheopposite-sides of the web 1 9 by the bead-18 and flange 20 so that the ring is adapted to slide outwardly within said-groove as itabuts against the lower end of the rib section 10 when said rib sections are-telescoped. hen the umbrella is opened, asfshown in Figure 1, the cover exerts a tension upon the ribs which would cause the sections thereof to telescope in the absence ,oit appropriate locking means for securing them in extended ppsition; One form of locking. means which may be employed for this purpose is shown in detail in Figures 7, 8, 9, 1O and 11 and, consists of .a clip 27 which is secured by welding or otherwise, at the upper. end of the rib sec tion 11, to. the .under face thereof. This clip is formed with an inclined resilient portion 28 which bends inwardly toward the rib section 10 as shown at 29 and is formed on the end of the bent portion with a head 30, adapted to play within the cub-away portion 14 of: the reinforcing piece 1?. The sides of the clip 27 are turned up to form flanges. 31. on opposite sides thereof, said flanges being apertured. as at 32. A brace 33 is furnished for each rib, one end of which is hingedly secured to a runner 34, theother end being apertured and pivotally secured to the clip 2Tbyineans of apin 35 passing through the aligned apertures in said end and in the flanges31. The brace is formed with a slot 36 having an end wall37, said slot being of such length that when thebrace the reinforcing'piece 13' so as to clear the end walls 155 and 16'of'the latter and to be freely slidablewitliin the bore of the reinforcing piece andtherihsection; Asa-sen is 'secured to the -rib"sec'tion 11, depression of the head 3O i'n, the" manner -,described; permits the 'ri-bsecticn 11 td-slide upwardly along the rib section 10 'towardthe rib "at taching ferrule 5. I g

"llhenthebrace '33 is out of parallelism withthe'rilisection 11 in thcp'o'sition shown in Figure -1,- the end wall 37 is out of contact with "the resilient portion 28 and the head aornormall lies in the plane of the end walls l5 and 16 of the-cutaway portion 14 preventingmaterial endwise movement of the ribseetion '11 relative to the rib section 10. Thehead fSO is, however, made of sub stantiallyf 'snialler' "dimensions than the cutaway portiea'ira to allowfor'distortion ot the parts oftheumbrella and for structural imperfections inits 'manufacture and a5;- sem'blyk When the umbrella is closed the clip Q K'liesadjac'ent the rib attaching ferrule 5, the latter being made suiiiciently lar e to permit the ribs to be folded over said clips'at the-ferrule.

The staff sections 3 and 4 are hollow, the lower staff section being contracted in diameter at its-upper endas shown at'38 in Figure F1, through which" contracted portion passesthe upper staff section"4, the latter beingprovided -a't its lOW8I 'e11d with an expanded portion "39 fitting the bore off-that part'of the lowerfstaff-fs'ection of largerdiam'eter: "That part of the's'tafi' section 4 which lies within-the contracted port-ion 38 of the stat? section 3 isalso' slightly: expanded, m'aking a tight 'fit' within said contractedportion.- l This Construction provides a-rigi'd jointbetwetenf'the two staff sections when extended and the abutting shoulders 40 formed ="between 'the parts "of diii'erent diameters prevents the staff sec tions from being pulled apart in the opening movem'enflof the umbrella. The expanded portion' -39' of the upper stafi' section '4 is bifurcated for a portion of its length for the purpose of straddling the spring catch 41 which is located within the lower-end of the-"staff section '3 and the function'- otwhich will-"bepresently explained. The-depending side portions 42, formed by this bifurcation are adapted to engage the plate-43, which forms part'of the stall lock in order to release the latter.

. staff seciions be relatively 'slightly twisted- Thedepending side portions are shaped intog'points so that should the upper and lower said depending side portionswill not catch BEST AVAILABLE COPY upon 'the'spring catch 41, but will slide by th sameyrestoring" said staff sections to their original relative postwar I The spring catch 41- is secured within the stafi'section 3 by means of'a, projection 44 passing through anaperture in the "wall of said staff section. 'Said spring catch has a back support 45 .resting against the opposite wall of thesta-if section and the head of saidnspring catch normally projects from a slot 46 preferably in longitudinal align inent with the projection 44.' This spring catch is for the purpose of latching the runner 34 when the umbrella is closed. "A spring catch. 47, which is slightly different in shapeg'but wsimilar to the spring catch 41 in its structural features is secured within the staff section 4, the head of said spring catch projecting through a slot in said staff section which is in alignment with the slot This spring catch latchesthe. runner in the openposition of the umbrella. The runner is secured to a quill 48 which is of s'uiiicient length to have a substantial bearing surface upon the stafli and of sulficient width to permitit to slide freely upon the larger portion of the sta'fi" section 3. Said quill is formed, intermediate its ends with a pair of oppositely located slots 49 and 50, said slots extending circumferentially through a wide angle, leaving between them a rib of metal 51 wide enough to afford proper support for the two ends of the quill 48. Slidably mounted upon said quill beneath the runner 34 is a sleeve 52 having-an expanded central portion-53 which is adapted to bridge the'slots 49 and without depressing whichever 'of the spring'catch 41 or 47 may be projecting therethrough. Above and below said ex panded portion the sleeve is contracted in such a manner that'when either of the con tracted portions is moved across the Zone of the slots 49 and 50, whichever stop member is projecting through said slots will he depressed flush with the surface of the staff. Said sleeve, then, is for the purpose of releasing therunncr 34 from either its upper or lower latched positions. Said sleeve is formed witha'transversely extending flange 54turned' up at the edge toprovide a rib. retainer for surroundhigthe balls 55 at the ends of the 'ribs. retaining tlie latter compactly together when the umbrella is closed.

A pair of spring stops 56,21nd 57 are sccured within the upper staff section 4 in a manner similar to that of the spring catches previously described, the former of said spring catches projecting through a slot 58 in the wall of said upper staff section and forming a shoulder against which the upper end of the quill 48 is adapted to abut, thus aiiordinga stop for limiting the upward movement ofthe'runner 34 beyond its nor ice mally open latched position. The: spring stop 57- p rojec ts through a slot 59,'adjace'nt the lower 'endJof-the upper, stafi section and functions to latch the two stafi sections in their entended position.

The reciprocatory movement of said hey is limited by the length vof oppositely arranged slots 67 through which'the rivet 6 passes. The up: per end of the key. projects from the outer end of the upper staff section and is secured in any suitable manner to a manually operable knob 68 which is manipulated in the opening and closing operation 01"; the umbrella. In the present instance a stud 69 having a threaded outer end is riveted in the end of the key 60, said outer end being screwed to a boss 70- on the inner side of the knob 68. Said knob is otherwise hollow, and when in its depressed position-encloses the washer 22 andthe outer end of the upper stafi section in a weather-tight manner. The peripheral flange 71 of said-knob makes close contact with the fabric cover of the umbrella, when the latter is spread, excluding moisture from the mechanism associated with the top of the staff. Engagement of said flange with the ribs, in the spread position of the umbrella, prevents accidental depression of the key to which would-permit collapse ,of the umbrella.

The case sections 1 and 2 telescope one within the other, the upper case section being contracted atv its lower end forming a shoulder 72. The lower case section 2 is. f d at s append i pm 73 of SEST AVAILABLE COPY larger diameter which abuts against the shoulder 72 when the casesections are extended preventing them being drawn apart when the umbrella is closed. The upper of the outer case section is provided witha flared outwardly rolled flange 7 4; which pre sentsa funnel shaped opening for the easy entrance of the fabnic of the umbrella and also aiiords a smooth sur-face which avoids injury to other articles with which the-fold ed umbrella may be packed; Said outer sec} tion is preferably formed of metal but may. if desired be of non-metallic material and finished in any desired manner to efl'ect the ornamentation to the umbrella. When the latter is opened the outer case section 1 forms the handle of theumbrella.

The inner case section 2 is provided near its upper end with a peripheral groove? 5 having beveled sides 76 and T7, theend ofsaid-case section above said groove, being reduced in internal diameter. and curved into an outwardly flaring lip, through which the folded cover of the umbrella may enter without impediment. The tapered walls of the groove are designed to cooperate with a staff lock on the lowerend oj-the lower staff. section 3 byineansotwhich the latter is retained in the upper end of the case seca tion 2 in the extended position of the rimbrella.

The lower end of the stafi section 3, is Surrounded by a quill 7 8 which tightly fits said stafisection and is formed with a reduced-upper end 'Z9jafiording a seat for the s fl trams w ch. i l d a a nu- 1& hub 8l having three or more inclined arms 82 extending therefrom at spaced intervals, each of arms being formed-with a thin resilient portion 83 and an integral rigid-portion 84 having a beveled projection 85 capable in certain positions of the staii of spreading, through the resiliency of the portion 83 and seatinglitself in the groove 75 in the inner case section. The lower.por-, tion 86 of each. arm are formedto extend radially toward the axis of the staff, the ends thereof being beveled as shown at 87 inFigure 3.

The quill 78 is, in turn, surrounded by a sliding sleeve 88, the cylindrical wall 89 of which is spaced from the quillZS, and atfords a chamber surroundingsaidquill in which is located the helical spring 90. Said spring bears at one end against the top. flange of the sleeve 88, and at its lower end against a ring 91 which is located upon a reduced portion 92 of said quill and retained in place by a flange 93, the latter being formed by riveting the lower edge of the reducedportion 92 over said ring.

The lower end of the cylindrical portion 89 of the sleeve 88 is formed with a wedge portion which has two degrees of taper, a very steep taper 95 and a gradual-taper 96.

The surface of said wedge portion may be continuous but the sleeve is here shown as split longitudinally so .as to provide a certain'but very slight degree of resiliency. in the parts to compensate for any lack of trueness in size or fit of the cooperating elements. Aperipheral groove 97 is formed within the lower end of the cylindrical portion of the sleeve8 8 in which issprung or otherwise seated the plate 13 against which the lower end of-the upper staff section .4; abuts as .has hereinbefore been described-l;

When the staff ofthe umbrella is drawn outwardly in the act .of -.-rai si ng itjthe frame travels with itnntilithe upper end of the inner .case. section 2 is reached at ,which point; theprojections5 of the arms 82 spring .into. the. peripheral. groove 75. This permits the tapered portion of the-isleeve 881.110 enterathe, space betweenthe ring 91 and; the; ends 87 of said .arn1s,sai d tapered portionn being ;i1npe lled by the expansion of the helical spring .90 firmly forcing the projections into, .contactwith thetapercd walls '76 and 'ilofthe groove 7.5 and'holding the staff .in rigid position-:relatively to the inner gcase; section 2. ..'Eurther outward pull upon the staff causes saidinner case section to travel outwardly. with said staff telescoping it within the outer case section 1.

-The inner case section 2 18 provided adjacent its outer end'witlr an annular reinforcing plate 98 having slots 99 formed on opposite sides thereof and registering with slots 100 formed in the wallet the inner casesection. Said reinforcing plate is also provided at its lower edgewith depressions 101. These depressions afi'ordseats for the extended edges 102 of thecase lock frame 103, the latter being a plate preferablyslightly convexed on its lower. side and having adjacent each endpairs of upstanding lugs 104 provided with the aligned apertures 105. These apertures are for the purpose of pivotally mounting the catches 106 which have pairs. of depending .lugs 107 hingedly cooperating with :the pairs of lugs 104. .-Each of said catchesis also provided with a nose 108 which is adapted to be projected throughone of the openings formed by the aligned slots 99 and 100 in the inner case sectlOn. Said catches are .each provided with a back plate 109 and are preferably formed with downturned flanges 110 which engage with a leaf spring 111 seated within the case lock frame 103. Said spring normally urging the noses 108 ofthe catches outwardly to a position in which they project slightly beyond the vwall of the inner case section. When said inner case section is drawn inwardly by pulling upon the staff of the umbrella after the staff lock engages the groove 75 the projecting noses of said catches are depressed by contact with the largest 91 ih-9l i9 .1 nd

YVhen -in this position-saidcase sections serve as a handle for the umbrella the latter then being open. I 1

' in the lowering of the umbrella the inward. thrustof the staflf .first forces the wedge shaped portion.96 of the staif lock outwardly against the tension ofvthe spring from-.-between the ends of thearms 82 and the ring .91 permitting the projections 85 of said arms to. ride ,over the'inclined wall 76 of the. groove 75 so that the lowerupon further. pressure on the stalf.,; .lVhen 1 the staff is at the limit of its-downward movement within the, lowercase section the steeply tapered surfaces .95 of said wedge shapedportions forcibly engage the ends of the arms v82 spreading themgagainst the inner wall of the inner case section with sufficient force so that they will surely enter slot- 75 when'brought opposite to it, but at the same time will slide within the case without undue friction or distortion of the case; also, the action of the steep-taper reversibly permitting the arms 82 to move back nearer the staff to ride over any inequalities in the case.

The lower end of the case section 2 is closed by a cap 112 which may be secured thereto in any desired way but is here shown as being formed with a flange 113 having cut away portions 114' forming oneelement of abreech block arrangement. The reinforcing plate 98 is provided with an outwardly extending flange 115 which is furnishe-zl with arcuate projecting portions 116 the latter being adapted to register with the cut-away portions 113 of the cap flange. 3

The upper shoulder of the flange 1150f the reinforcing plate lies in an inclined plane forming a shoulder slightly spaced apart from the bottom end of the inner-case section 2. When the complementary breech hlock parts of the cap and flange 115 are placed into registration the'cap is given a partial turn causing it to tighten against the lower edge of the flange 115by virtue of said inclined shoulder. f

The mechanical tetion' of the umbrella during the closing" increment is es follows: Drawing dbwn the rib reteinei' 54 with 'thezittafched sleeve has depressed the spring czitch 1&7 thereb" permitting the quill runner to be drawn-down the and acting thro gh the braces 33 to cose the ribs in the hs'na'hmanne'r; When the quill 8 passes" over the spring- Cilt'll 41 it depressesthe mien-bet vhe'n the ribs are up roximately par-allele) the-staff said spring Catch snaps into'o'ne of the "opening's'in the quill and halts it and the 'rrinner dotvn. When ther'ibs areheld c'lo'se 'tothe the end 37 ef the slot 36 presses i'i'ponthie rel iilient portion 28 of the clip 27 sot'h-at the head 30 of said clip is raised out of the plane ofthe were 15 the 1'6 ofthe slot that the rib section 11 it free to slide longitudr na'lly with-respect to-th'e rib section 10'.

Pressure on the c'a pf68 nioves the key 60 down within then'pp'e'rseetionfthereby depressingthe springfs'topsfifi and 57 helor' the srirfl'e e of eai'd staff section, permitting the latter "t6 slide Within the lower 's'tafi'eection 3. The pufif dse 0f depressing the spring 56 has already been ekpleinedp til pressure causes the latter to slide within the lower staff section and at the same time causes the rib sections 11' to telescope over the rib sections 10, thus shortening the timbreila. When the telescoping of the ribs is nearly complete the outer ends of the rib sections 10, come into contact with the split rings 26 and forces them along through the grooves in the rib sections 11 toward the outer ends of said rib sections sothat when the operation is' complete the folding of the fabric cover is as shown at 118 in Figure 2. Continued pressure on the cap 68 brings-the lower end of the upper staii section into contact with plate 43 and acting through said plate and the sleeve 88 compresses the helical spring 190 forcing down' the wedge'sliaped portions of s'aid sleeve, permittingthe projections "to rid e out of the peripheral groove 75" a-nd so to release, the stall: lock causing the entireframe to move within the innerjcasef'jsectionj 2. When the spring 90 is sufiiciently -coinpressed to release the staff lock, thefribj'attacliing sleeve 5 restson the upper endiof ,the lower stali' section, thus relieyingjlie spring,' the plate 43 aud'the sleeve 88' of any "furtherfstrain.

When the j 'wfedge' shaped portion V of the sleeve 88 approaches 'the'flower end of the inner case section 'it'comes in contact with the catches of the case lock and by compressing theispring 111 draws said catches out from their seat on the shoulder 72-thus releasing the case lock and permitting'the inner and outer case sections to, slide one without theother, extendingthe case to its full length, permitting the'entire frame, and cover ot-the umbrella to enter thejcase the upper endof the outer case section being closed by the flange 71 of the cap 68 as-is clearly shown in Figure 2. This completes the operation of closing. It will be observed that the cover was first forced into one of the case sections and then into the other as a sequential operation, thus requiring only about one-half as much strain on the cover and parts as would be required to force the cover into a one-piece case of the same 'dimensions.

It is, however, within the scope of the invention to substitute a one-piece case for the telescopic sectional case herein described, said substitution effecting a simplification in the mechanism by omitting the elements of the case lock and the case parts with which it cooperates. It would of course be obviously impossible to make a one-piece case as short as a two-piece casing which in most instances might militate against its appearance as a handle and render it somewhat inconvenient to pack or carry.

While I have above described what I have found to be a very practical embodi meat of my invention, it is nevertheless to be understood that the telescopic umbrella BEST AVAlLABLE COP may also he exemplified in numerous other alternative constructions and I accordingly i'eserv'e'the right of adoptin all such legitimate changes as may beiairly embodied within the spirit and scope ofthe invention as claimed.- 1
