C. R. GEISEL FOLDING UMBRELLA Feb. 19, 1935.

Filed May 16, 1955 Patented Feb. 19, 1935 Y half to Eugene Carl R. Geisel, `Windsor, Conn., assgnor of one- A.' La Brie, Hartford, Conn.

Application yMay 1G, maaserial No. 671,336 150mm. (o1.V 13s-725) .Y ,My invention relates to folding 'umbrellasand more particularly to Vthat class of umbrellas Which can be collapsed into a Vsmall and com'- pact'form which will fit yinto a small compart.

mentsuch asin a ladys handbag, atraveling bag he object Vof my invention is primarily to providean umbrella of the character described which isv simple in its operation.L

. A further object is to provide such an umbrella which is durable Vandso constructed that it is strongly braced whenrin its open position.

- An improved umbrella comprising my invention and by which the objects above set out may be attained, is illustrated in the accompanying drawing in which: l

Figure 1 is a View ofthe umbrella as it appears in its openvposition, but showing only, two of the oppositely disposed ribs v"for the purpose Aof sim# plifying the illustration. Figure 2 is a view showi gthesame in a partly closed position. L 1

Figure 3 is an enlargedview showingthe umbrella completely collapsed; 'the rbottom' portion oi the stai and handle being shown in central vertical section. l Y

Figure 4 is a view similar to Figure 3, but showingthe position of the umbrellaat thestart of the opening operation; the lower portion'of the umbrella only being shown.

Eigure5 is. aurther enlarged view in central vertical section on aline between the ribs, with some of the parts broken away; Ythe st a being shown in collapsed position while the umbrella vis in its .open position. f Y Y Y y l A rEigure 6-is a. detailview showing the construction of the staff sections..

Referring to the drawing in which like reference numerals denotecorresponding parts in the different views, thenumeral 5 indicates astaf and 6 aV handle secured to the end thereof. I The said staff is composed of telescoping sections7,

l

8 and 9. Each of the

sections

7 and 8 is reduced at"the bottom thereof ltovform tapered Walls ,10. The upper ends of the sectionsS-and 9 are provided with expanding' tapered walls 1l which, whenv the staff is extended,.will engage the tapered Walls 10A and thus form a frictional lock to retainsaid sections securely in the extended position.' Q In' order to provide a more secure engagement between the sections, I provide bushings 12.whi'ch are rigidly secured to theupper .ends ofthe

sections

8 and 9, and which form the tapered walls 11 above described.v`lr Y v A collar 2O is slidably mounted on the sadex-` ytop section of the staff 5, and "nasa camming flange 18 and a tubularl extension-19 extending above the said flange. y f

tension 19 and the said extension is flaredoutwardlyfat 'the topthereof, as Yat 21, to limit the sliding movement of said collar thereon. The handle is threaded tothe section 9 of the staff as Vat 22, and is provided with a recess 23 to receive the runner 17 when the umbrella is Aco1- lapsed as clearly shown in Figure 3." Y

A cap 24 is threaded to the extension 16 of the collar 13, and is providedwith recesses 25 in the 25 top thereof to receive a wrench for .turningthe same. ,l l v f A spring lockingpin 26 is securedto. the said cap 24. The said pin is provided with k a head 27 contractior'rof the said head. A locking groove 29 is formed atI the inside vof Vthe section 91tobe engaged bythe Ysaid locking Apin head 27 when the staff4 of the umbrella is collapsed as illustrated inFigure `5.v Y j- .Y -f Collapsible ribs 30 lare provided. Theseribs are constructed in aform commonly known as lazy tongs, and comprisea lseriesof one or more tong sections which are pivoted 'together at their ends. Y YAs illustrated vin ,the drawing,A I have shown each oflthese ribs having two tong sections. The first Aof said sections comprising a link 31 which is pivoted `to thecollar 2() and has an offset pore tion 32fformed` to vsupport the cover 33 of the 45 umbrella when the said umbrellais in its-open Cil of the link 36, and to the link 39 as at 41. 'Iips 42, such as commonly used on umbrellas are provided at the ends of the links 39 to which is attached the umbrella cover 33 by means of sew ing the 'said cover thru openings in the said tips.

The pivots 43, connecting the link sections adjacent the umbrella cover, are tubular in construction to provide openings 44 thru which is sewed the cover 33. v

The links 40 are provided With cam extensions 45.

When the ribs are extended to the open position as shown in Figure 1, the extensions 45 enengaging gage the links 37 of the adjacent tong sections,

thus preventing further closing of saidtong sections and retaining the relation of the rib sections in a position which will render a strong-Y ly braced rib.

In order to secure the umbrella cover 33 at the center thereof, I provide a ring- 46 to which the said cover is Vsewed.l Y The said ring fits over and surrounds' the extension 16 of the collar 13. washer 47, preferably of leather, is provided over the said ring and pressed firmly in engagement thereon by the cap L24 which is threaded to said extension. l

To'retain my improved umbrella in its open position, I provide a hook 48 whichv is pivoted on the collar 20 and located between two of the ribs 30. The Vsaid hook is provided with a cam tail 49 which projects thru an opening 50 in the camming flange 18. A spring 51 is provided to force the said hook into engagement with the locking groove 15 when the umbrella is in its open position.

In order to minimize the friction between the various links at their lpivotal connections, I provide spacing washers 52 at each point where the links are pivoted together.

- 'Ihe operation of my improved umbrella is as follows: H j

When it is desired to open the said umbrella from its collapsed position illustrated in Figure 3,' the handle 6 is pulled downwardly'extending the staff to theposition shown Figure 1. The runner 17 is thenV pushed upwardly causing the cam 18 to engage the cam engaging extensions 45 on the ribs and force them outwardly thus starting the opening operation of the umbrella as clearly illustrated in Figure 4.

Raising the said runner will also disengagethe tailV 49 ofthe hookr48 permitting the said hook to -be moved forward by the action of the spring 51. A continuation of the operation of raising said runner 17 will open the umbrella thruthe position shown in Figure 2 to the completely open position shown in Figure 1. When the umbrella is yabout to reach its completely open position, the YVhook 48 will engage the locking groove 15, in the collar 13, and thus retain the umbrella in the said openV position. Thus, the extending of theV staff 5 and the raising of the runner 17 thereon, may be performed in one single manual op.- eration which will resultinopening the umbrella from its entirely collapsed position shown Vin Figure 3, to its entirely opened position shown in Figure 1.

In closing the said umbrella from the position shown in Figure 1, vthe same is held by the handle 6 in one hand and the runner 17 is graspedin the other. The said runneris pulled downwardly, lowering the ycaml and forcing the tail 49 of the hook 48finwardly, releasing the hook from` its lengaf-enirerit With the locking groove 15. Continuing thev lowering of the said runner will close the umbrella back thru the position shown in Figure 2 to that shown in Figure 3. The operation of collapsing the staff being completed by forcing upwardly on the handle 6 after the ribs have been collapsed.

While I have shownV and described an umbrella by which the above objects are attained, it is to be understood that the construction of the same may be changed toa `greater ,o rjlesser extentlwithout departing from the scope of my invention as set out in the following claims.
