SIGMUNID SCI-ILESINGER, OF BROOKLYN, NEW YORK.

UMBRELLA.

Specification of Letters Patent.

Patented Mar. 27, 1917.

Application filed December 7, 1914. Serial No. 875,867.

To all whom it may concern:

Be it known that I, Srsrrunn SoHLnsINGnR, a citizen of the United States, and resident of New York city, borough of Brooklyn, in the county "of Kings and State of New York, have invented certain new and useful improvements in Umbrellas, of which the following is a specification.

One of the objects or" my invention is to provide simple and improved means to permit an umbrella to be turned inside out, as when it is subjected to severe wind pressure.

Another object of my invention is to pro-.

vide improved means to retain the ribs in a closed position when the umbrella is folded or closed.

My invention comprises novel details of improvement and combinations of parts that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming part hereof, wherein,

Figure l is a partly broken side elevation of an umbrella embodying my invention;

Fig. 2 is a substantially similar view showing the umbrella partly reversed;

Fig. 3 is an enlarged vertical section illustrating a portion of the umbrella, shown reversed or turned inside out,

Fig. 4. is an enlarged detail showing parts of the umbrella in a closed position, and

Fig. 5 is a detail sectional view of a portion of the umbrella showing my improvements adapted to retain the ribs of the um brella in the closed position.

Similar numerals of reference indicate corresponding parts in the several views.

The umbrella to which my improvements may be applied may be made in any suitable or wellknown manner, and may comprise a rod 1, the ribs 2, pivotally attached to the rod by the notched ring at 3 in an ordinary Way, said ribs being pivotally connected with the stretcher rods 4; as usual, or in any suitable manner. The inner or lower ends of the stretcher rods are pivotallyconnected at 5 to the notched ring 6 that freely surrounds and is slidable relatively to rod 1. The fabric 7 may be applied upon the umbrella in a Wellknown manner. The ring 6 is slidably mounted upon a tube 8, which tube is mounted to slide upon the rod 1. Said tube is adapted to be retained, when the umbrella is opened, by coaction with a spring-acting stop 9 carried by the rod in an ordinary manner, and at 10 is a spring-acting stop carried by rod 1 and spaced from stop 9 to coact with a slot 8 of tube 8 to hold the umbrella closed in an ordinary way. At 11 is a spring shown coiled around tube 8 above ring 6, said spring bearing at one end against said ring and at its upper end against a stop 8" on tube 8, which stop may be formed by bending the upper end of tube 8 outwardly. The arrangement is such that spring 11 will tend to press ring 6 normally against a shoulder or stop 8 on tube 8, whereby ring 6 is normally maintained in the operative position with respect to tube 8.

lVhen tube 8 israised and lowered the ring 6 and spring ll'will be moved equally with said tube. Ring 6 being normally maintained by spring 11 against shoulder or stop S will be. pushed upwardly by said shoulder or stop when tube 8 is pushed outwardly along rod 1 for the purpose of opening the umbrella, and ring 6 will push upon the stretcher rods 1- to distend the umbrella so that when the tube 8 rests against the stop 9 the umbrella will be retained in the opened position. I have shown the tube 8 of such length as to provide a space 12 between the outer end of tube 8 and the notched ring 3 when the umbrella is in the normally open position (Fig. 1), whereby, it wind pressure tends to open the umbrella tube 8, ring 6, stretcher rods a, and spring 11 may move together outwardly along rod 1 until said tube is stopped by the ring 3. It the wind pressure is excessive and tends to turn the umbrella inside out, the stretcher rods 4:, by pulling upon ring 6, will tend to compress spring 11 and as ring 6 may then slide freely along tube 8 until the final oompressi'on of spring 11, the umbrella may turn inside out without danger of breaking it, (see Fig. When the umbrella is next turned back to its normal condition the ring 6 may slide "along tube 8 assisted by spring 11, and tube 8 will again rest against stop 9. Spring 11, it will be observed, performs the double function of retaining ring 6 and the stretchers 4 in the normal position upon tube 8 and of permitting ring 6 to assume an abnormal position on tube 8 when the umbrella is turned inside out, thereby relieving the umbrella from becoming broken under high wind pressure. WVhen the umbrella is to be closed the spring 11 by holding ring 6 against shoulder or stop 8 of tube 8 enables said ring to draw or pull the stretcher rods and ribs to the normal closed position.

Since the tube 8 is slidable within the ring 6, in a direction toward the umbrella handle 1, it aifords a convenient means to retain the umbrella closed. By having the stop 10 so located upon the umbrella rod 1, with respect to the position of ring 6 when the umbrella is closed, that the tube 8 must be pulled against the tension of spring 11 in order that the stop 10 may enter the slot 8 of said tube, the tension of the spring, with the parts in the position shown in Fig. 1, serves to draw the tube 8 outwardly, causing the metal at the lower edge of slot 8 to engage the stop 10. The shoulder 8 will then be out of engagement with ring 6, so that the spring 11 may draw tube 8 against stop 10 in the manner stated, and as spring 11 will then continue to bear against ring 6 the umbrella will be kept from springing open spontaneously.

As a means to retain the tips of the ribs 2 closed, the outer end of tube 8 may be provided with a retainer 14- 'for the ribs, as shown in Fig. 5, in which case it will not be necessary to have the metal at the outer end of slot 8 engage the stop 10, although this may be done if desired.

Said retainer is shown in substantially hollow or cup-like form surrounding the end of tube 8 and adapted to receive the tips of the ribs, which retainer may be formed on or applied to tube 8 as desired. With this arrangement it will be observed that when the umbrella is to be closed the retainer 1 1 may be pulled outwardly, as in dotted lines in Fig. 5, tube 8 thereby sliding through ring 6, (which is then retained by the stretcher rods 4:), and compressing spring 11, whereupon the tips of the ribs may be drawn together and held, and then retainer 14' may be released to inclose or receive the tips of the ribs, the spring 11 then, by bearing against ring 6 and the stop 8 causing tube 8 to be slid outwardly along rod 1 to retain the ribs closed, as in Fig. To release the ribs the retainer 14 is pulled out and then released.

Changes may be made in the details of construction and arrangements of parts set forth, as the same may be varied, within the scope of the appended claims, without departing from the spirit of the invention.

Having now described my invention what I claim is 1. An umbrella comprising a rod, ribs attached thereto, a tube slidable upon the rod, a ring slidable upon the tube, stretcher rods pivotally connecting said ring with the ribs, a spring positioned between the ring and one end of the tube, the tube having a stop to engage the ring, and means to retain said tube and ring elevated, said tube having a retainer for the rib tips located at the outer end of the tube.

2. An umbrella having a rod, ribs attached thereto, a tube slidable upon the rod, a ring slidable upon the tube, stretcher rods pivotally connecting said ring with the ribs, a spring coacting with said tube and ring, and means to retain said tube and ring elevated,

said tube having a slot, a stop on the rod to enter said slot, said tube having a retainer for the rib tips located at the outer end of the tube, said retainer comprising a hollow member adapted to receive the rib tips, said slot being longer than thestop to permit the tube to slide to engage the retainer with the rib tips while said stop is in said slot.

3. In an umbrella, a rod, a notched ring on the rod, ribs attached thereto, a tubular member slidable on the rod a stop forming a part of the tubularmember, stretcher ribs, a ring to which the stretcher ribs are secured, said ring adapted to slide on the tubular member, a spring mounted between the ring and stop, said spring adapted to contract under excessive wind pressure in one direction whereby the tubular member is moved longitudinally of the rod and into engagement with the notched ring.
