Specication of Letters Patent.

Fatented ct. 18, 19150.

Application led August 2, 1910. Serial No. 575,170.

The present invention relates to improve` ments in folding'umbrellas, and more particularly to that class in which the ribs, braces andthe staff or stick are composed of .a plurality of slidably engaged sections.

One of the objects of the invention is to simplify and improve the construction and and to provide one which is of a very simple, strong, and durable construction, and easy'to operate.

Another object of the invention is to provide an umbrella which may be folded into a very compact and small bundle, which can 'be carried in the pocket or Satchel, the umbrella being in the form' oa small cylindrical package only a Afew inches in diameter and a few inches in length.

With these and other objects in view, which will appear as the invention is better understood, the same consists in the construction, arrangement and' combination of parts hereinafter fully described, pointed out vin the appended claims, and illustrated in the accompanying drawings, it being understood that various changes may be made in the size and proportion of' the parts, and minor details of construction without departing from the spirit or sacrificing any of lgheadvantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accom-A panying drawings, in which Y Figure 1 is a side elevation of the urnbrella stick, one of the ribs and one of the brace pairs of theimproved umbrella, showing themin their extended or open positions; Fig. 2 is asimilar view showing the rib and the braces in their closed positions; Fig. 3 is a similar view showing all parts folded or collapsed; Fig. 4: is a plan view of one of the ribs; Fig. 5 is a section taken on line 5 5 of Fig. 4; and Fig. 6 is a vertical l cross section ofthe umbrella stick in its ex- -'tended position.

In the present embodiment of the invention, the sta or4 stick is composed of six tubular sections 6, 7, 8, 9, i() and il.. @t

these the sections Sand 9 are iixedly attached to each therzand within each other. while the other sections aretelescoped into the sections 8 and '9. t'is,-ot` course, obvious that the stick may consist of a greater or less number of sections. The stick sections are held in .their extended positions, shown in Figs. 1 and 2, by means of. spring catches 12, 12, rlhe spring catch attached.

to section 'rests then upon the upper edge of the section 7, and the springcatch of thel latter section engages the upper closed ends of the section S and 9. ln a similar manner rests the spring catch of the section 9 upon the upper edge of the section 10, and the catch of the section l() upon the upper edge of the section 11'. The construction of these 'spring' catches need not be described, as the saine is well known in the' art. The disengagement of vthe stick sections from each other is prevented by suitable stops 12. The lower end of the 'stick section 1,1 is provided with a suitable handle 13. To the section 7 of the stick is secured a' notch disk 1st, to which the inner ends of the ribs l5 are lpivoted. A notch disk 16 is fastened to the section 8 of the stick, to which are pivotally attached the inner ends o'j the main stretchers 17, their outer ends being in a similar manner attached `to the ribs 1:3. The runner oi the umbrella is indicated at 18,

'having attached thereto the inner ends oi auxiliary stretchers 15), the outer ends oit which engage pivotally the stretchers 1T.

The rib is formed or' three sections 20, 21 and 22, or' which the sections 2O and 22 are slidably held upon the section 21. This latter section is of U-shaped cross section, hav ing a partition running throughout the length thereof, whereby two channels Qi The section20` and 25 are formed therein. slides into the channel 24, while the section 22 slides into the channel 25, when the ribs ci. the umbrella are collapsed. To prevent the rib section 2O from telescoping into the section 21, when thc'unihrella is in its open position, a spring pressed. locking lever 2G is pivotally attached at 27 to the rib section 2l, its nose engaging the end of the rib section 20, while vits iree end pro jects toward the stretcher 17, for a purpose hereinafter to be specified The rib section 22 is prevented frein telescoping yinto the section 21 by means of 1a spring stop 30, ii'xedly attached at 30 to the rib section 21, and having an inwardly projecting finger 31 engaging the end of the section 22. An extension 32 of the spring stop projects into the channel 2dr of the rib section 21 and into the path of the end of the rib section 20, in -telescoping The stretcher l'ffismade of two sections 33 and 34, which are pivotally secured to gether at 35. These stretcher sections and also the stretcher 19 are of U-shaped cross sections, and more particularly the cross'section of the stretcher section 3311s somewhat 14, so that, when the umbre a is being collapsed, the covering can be folded without detachinggthe saine from the frame.,

When it is desired to close the umbrella from its position shown in Fig. 1 to that shown in Fig. 2, the spring catch 36 upon the stick section 8 is forced into the stick sufficiently to be disengaged from the runner 18. The runner can the'n be pulled down-ward toward the handle 13, whereby the umbrella will be closed in the usual manner. v

To open the umbrella, that is tok bring it from the position shown in Fig. 2 to that shown in Fig. 1 of the drawings, the runner 18 is taken hold of and pushed toward the notch disk 16, and until the lower end of the runner is brought to rest upon the pointed end of the spring catch 36.

When it is desired to fold the umbrella, or in other words to reduce its length shown in Fig. 2 to that shown in Fig. 3, .first the spring catch of the stick section 6 is pressed inwardly, whereby the section-6 can be slid into section 7. In telescoping the section 6 into section 7, the lower end of the former will disengagethe spring catch 12 0j? section 7 'fromthe section 8, whereby the section 7 can be telescopcd into the section 9,'and at the same time the rib section 20 into 'the rib section 21. It will be observed that in closing the umbrella from the position shown in Fig. 1 to that shown in Fig; 2 of the drawings, the stretcher sections 33 will force the noses of the locking levers 26 out of engagfement with the outer ends ofthe rib sections 20, allowing thereby the latter to slide into the sections 21. The outer ends of -the rib sections 2O lift the projections 32 of the spring stops 30, and disengage thereby the lingers 31 of said stops from the inner ends of the rib sections 22, allowing them to slide into the sections 21. When the spring catch 12 upon section 10 of the stick is forced inwardly, the section 10 can be telescoped into section 11. In this position the bell 37 upon section 11 is broughtinto engagement with,

the outer ends of the rib sections 22, after which thesection 10 is telescoped into the Lstick section 8 5 the spring catch 12 ofthe section 9 having been previously disengaged.

from thesection l0 as .the section 7 of the stick was telescoped into the section 9, in the same manner as the section 6 disengages the spring catch of the section 7 from sec` tion 8. The rib sections 22 telescope with the movement of the stick section 10. `In

order to extend the umbrella, obviously the i reverse operations are necessary.

What I claim is 1. In a folding umbrella, the combination i with an umbrella stick made of va plurality of sections, of telescoping ribs each composed of an inner section pivotally connected to said stick, a middle section and an outer section, said .inner andouter sections being slidably arranged lengthwise upon the. middle-sections, a' notch disk secured to one of said stick sections, main stretcherstpivotally connected'to said notch disk and to the mid- 'dle sections of said ribs, a runner slidably arranged upon said stick, and auxiliary stretchers connected to said runner and said main stretchers.
