UNITED ALBERT B. TURNER, OF NEW YORK, N. Y.

FOLDING UMBRELLA.

'7 Application filed October 23, 1920. Serial'No. 419,030.

T all whom it may concern:

Be it known that I, ALBERT B. TURNER, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented new and useful Improvements in Folding Umbrellas, of which the following is a specification.

This invention relates to umbrellas and particularly to folding umbrellas, and one of the principal objects is to produce a device of this nature which may be folded into a compact bundle.

Another object is to provide a plurality of sleeves operable for effecting folding and unfolding of the device.

Another object is to provide novel means for locking the sleeves together for operation as a unit.

Another object is to provide a handle which may be screwed up over the sleeves for holding the device folded.

With these and other objects in view which will be apparent as the specification proceeds, the invention resides in certain novel construction and combination and arrangement of parts hereinafter described and claimed, and illustrated 1n the accompanying drawing forming part of this speci fication and, in which Figure 1 is a vertical sectional view of my improved umbrella in folded condition.

Figure 2 is a similar view with the outer sleeve raised to partly open the umbrella.

Figure 3 is a similar view showing the umbrella fully opened.

Figure & is a detail fragmentary view showing the means for locking the sleeves together.

Like characters of reference refer to like parts in all views.

This invention contemplates providing an umbrella with jointed ribs and with concentric sleeves mounted on the umbrella rod and one movable on the other for operating the outer sections of the ribs and both movable as a unit for effecting operation of the ribs as a whole.

Referring to the drawing in detail, 10 represents the central rod of the umbrella, provided with the usual notched crown 11 for pivotally supporting the ribs to which the fabric cover is secured. The ribs in the present instance comprise sections 12 and 13 which are pivotally connected at 14.

Slidably mounted on the rod 10 is aslecvc 15 having a crown 16 secured at its upper end. Struts 17 are pivotally mounted at one end in the crown 16 and pivotally connected at their other end to the section 12 at 18. A spring catch 19 inthe rod 10 is adapted tov hold the sleeve 15 in its upper position.

Mounted to slide over sleeve 15 is a sleeve 20 having a crown 21 at its upper end in which are pivotally mounted struts 22 the opposite ends of which are pivotally connected at 23 to the inner extensions 24: of sections 13. When sleeve 20 is moved to the position shown in Figure 2, it is above catch 19 so as to permit operation of the same to allow downward movement of sleeves 15 and 20 in unison. The sleeves are retained in lowered position as shown in Figure 3, by a spring catch 25.

The lower end of rod 10 is provided with a screw threaded boss 26 and onto this is adapted to screw a hollow handle section 27 which may be screwed over the sleeves 15 and 20 as shown in Figure 1 to hold the same in closed position.

The sleeve 15 is provided with a pin 28 adapted to ride in agroove or slot 29 in sleeve 20. A collar 30 is swivelled on the lower end of sleeve 20 and has a bayonet slot 31 whereby when the sleeves are moved 8 to the position shown in Figures 2 and 4-, movement of collar 30 will either lock or unlock the sleevesu In operation, the operator first unscrews the handle 2'? so as to permit free movement of the sleeves. He then raises sleeve 20 to the position shown in Figure 2 and by twisting collar 30 slightly effects engagement of elements 28 and 31 to lock the sleeves together. The two sleeves are then brought down rod 10 to the position shown in Figure 3. The initial movement of'sleeve 20 has by means of the struts 22 moved the sections 13 until they form substantially a single straight rib with sections 12, and the movement of both sleeves down has caused struts 17 and 22, to effect an expanding of the ribs 1213 to their fully opened position.

The catch 19 projects into slot 29 in the position shown in Figure 1 and rides therein when the parts are being moved to the posifore do not ,limit myself to theiexact details of construction herein set forth nor to :anything less than the Whole of my invention limited only by the appended claim.

l Vhat is claimed as new is A foldable umbrella of the character described comprising a central rod, an exteriorly screw threaded boss secured to the lower end of the rod, a hollow handle section having interior screw threads adapted to receive the screw threads of the boss and said sect-ion being slidable to its entire length on the rod, a pair of sleeves telescopically arranged one Within the other and slidab'ly secured on the rod :in a ananner to be engaged by (the handle section when the umbrella is in folded position, ribs radially extending from the upper end of said rod for a pivotal connection therewith, stretchers pivotally secured to the tops of said sleeves and With said ribs, the outermost of said sleeves being slotted, a stud projecting from the innermost sleeve for movement in the slot and a plurality of spring catches secured on the rod as and for the purpose specified.

In testimony whereof I have afiixed my signature.

ALBERT B. TURNER.
