FOLDING UMBRELLA.

Specification of Letters Patent.

Patented J an. 12, 1915.

Application filed June 6, 1914.. Serial No. 843,330.

To all whom it may concern:

Be it known that I, AUGUsT STEIN, a subject of the Emperor of Austria-Hungary, residing at the city of St. Louis, State of Missouri, United States, have invented a certain new and useful Folding Umbrella, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to folding umbrellas and, more particularly, to improvements in that class of folding umbrellas shown and described in my prior Patent No. 1,096,6i7, granted May 12, 1914.

In the accompanying drawings, which illustrate one form of umbrella made in accordance with my invention, Figure 1 is a View showing the umbrella extended, the cover being omitted; Fig. 2 is an enlarged detail view showing the telescoping" joint in one of the ribs, the ribs being extended; Fig. 3 is a view similar to Fig. 2, but showing the joint retracted; and Fig. 4 is an enlarged sectional view showing the operating joint in the stick.

Like marks of reference refer to similar parts in the several views of the drawings.

6 represents the main portion of the stem. Pivoted to this stem 6 at 7 are the inner sections 8 of the ribs. Pivoted to each of these inner sections 8 at 9 is a spreader 10. The spreaders 10 are also connected by means of struts 11 to the parts 8 and the inner ends of each of the spreaders is pivoted to a main spreader ring 12. In addition to the spreader ring 12, the umbrella is provided with an auxiliary spreader ring consisting of two parts 13 and 14 respectively, the flexible connections 15 being secured to the part 13, and struts 16 to the part 14:. The two sections of the ribs are folded together by the separation of the spreader rings in exactly the same manner as is described in my prior patent above referred to and, hence, the connections therefor will not be described in detail. The inner section of each of the ribs consists. in addition to the part 8, of a part 18, which telescopes therewith. The part 18 is pivoted at 19 to the outer section 20 of the rib. This outer section 20 is operated by means of a link 21 in the same manner as has been described in my prior patent. The action of the link 21, however, in the present instance, not only causes the section 20 of the rib to fold but, at the same time, causes the part 18 of the inner section to telescope with the part 8 thereof, so as to allow slack in the cover and thus prevent danger of injury to the cover by its being folded against the ends of the parts 18 and 19. In order to normally hold the part 18 in its extended position,'I provide a sliding oint 22 which is surrounded by a spring 23 bearing against the part 18 and against the end of the spreader 10. In order to provide for spring pressure in assisting to close the umbrella, the part 13 of the auxiliary spreader ring is carried on the end of the tube 28 which tube surrounds the tube 26 carrying the main spreader ring 12 and is itself surrounded by a spring barrel 25 containing a coil spring 29. This coil spring 29 bears at its upper end against the spring barrel 25 and at its lower end against the flange 30 carried by the tube 28. The lower end of the spring barrel 25 is pivoted at 31 to a link 32 which is in turn pivoted at 33 to an extension 84; of the lower part 85 of the stick. This extension 31 has pivoted to it a link 86 which is, in turn. pivoted to a sliding spring detent 37. This detent 87 is adapted to cooperate with hooks 38 on the link 32 to hold the umbrella in its extended or raised position, and to coiiperate with hooks 39 on the handle 35 to hold thrumbrella in its folded position.

The operation of my device will be evident from the above description. \Vhen it is desired to fold the umbrella. the spring detent 87 is disengaged from the books 38 and the handle moved into the pos tion illustrated by Fig. 4. This'action will separate the spreader rings, as has been described in my prior patent, and will fold the sections 8 and 20 of the ribs together. as shown in Fig. 3. and, at the same time, will cause the part 18 to telescope with the part 18 as indicated in this figure. so as to shorten the ribs and thus allow suihcient slack in the cover to prevent the cover being iniured by pressure against the parts 18 and 20. The tendency of the spring 29 is to force the tube 28 carrying the auxiliary spreader ring downwardly and thus cause the ribs to be folded together more quickly than would be accomplished without the use of this spring. After the parts are completely folded togather, the spring detent 37 will be brought.

into position to engage with the hooks 39 and thus hold the parts in their folded or closed position.

Having fully described my invention, what I claim as new and desire to secure by Letters-Patent of the United States of America 1s:

1. In a folding umbrella, the combination with a handle, of ribs hinged near the middle of their length, operative connections for causing said ribs to fold, and means for v shortening one portion of the folded rib to by .the folding of said handle for simultaneously folding said ribs and closing said telescopic joint to allow slack in the cover.

4. In a folding umbrella, the combination with a handle, of ribs hinged near the middle of their length, a pair of spreader rings, connections for folding said ribs by the relative movement of said spreader rings, and a spring normally preventing the separation of said spreader rings.

5. In a folding umbrella, the combination with a folding handle, of ribs hinged near the middle of their length, connections operated by the folding of said handle for folding said ribs, and a slidingly mounted detent carried on said handle, said detent operated in one position to hold the umbrella in open position and in another to hold said umbrella in closed position.

In testimony whereof, I have hereunto set my hand and afiixed my seal in the presence of two subscribing Witnesses.
