Application filed July 17, 1899. Serial No. 724,134. \No motleLl To all whom it may concern.- In my previous patent, No. 599,623, dated Be it known that I, WALTER E. MOULTON, February 22, 1898, I have shown a construc a citizen of the United States, residing at tion wherein the socket for the spherical end Shelby, in the county of Richland and State of the stretcher is madeintegral with the rib. of Ohio, have invented certain new and use In the present device, however, while emfnl Improvements in Umbrellas, of which the ploying a rounded socket or seat forthe outer following is a specification. spherical end of the stretcher I make it in a My present invention relates to umbrellas, somewhat different manner.

To hold thecup or disk S in place, Iemploy a nut U, which is screwed up against the under face of said disk, and a locking-nut V. The balls R are held directly up against the spherical heads of the stretchers and form, in connection with the sockets P, a superior bearing for said heads.

By theuse ofthe nutsUandVthe cup ordisk S and the balls R supported thereby may be adjusted to a nicety, so that the spherical ends of the stretchers will be held in their proper position.

No claim is made herein to the ball-andsocket connection between the rib and stretcher, as that forms the subject-matter of a divisional application filed by me, in pur suance of the requirement made by the Oflice, on the 25th day of October, 1899, Serial No. 73%,743.

Having thus described my invention, what I claim is 1. In an umbrella, the combination of a series of ribs; a series of stretchers connected thereto and provided with spherical heads upon their inner ends; a tube or sleeve having a collar extending outward therefrom and provided with radial slots; sockets or bearing-surfaces formed in the body adjacent to said slots; a groove or channel Q around the base of said collar; a cup or disk provided with a groove or channel in its upper face; a series of balls seated in said groove in a plane beneath and bearing against the spherical heads of the stretchers; and means for holding said cup or disk in place beneath the collar, whereby the balls are caused to bear against the spherical heads of the stretchers, substantially as described.

2. In an umbrella, the combination ofa series of ribs; a series of stretchers connected thereto and provided with spherical heads upon their inner ends; a runner provided With a series of spherical bearing-surfaces adapted to receive and hold said spherical heads;

and a series of balls held beneath said heads in a plane below the bearing-surfaces, said balls serving to hold the heads in the bearing-surfaces, substantially as and for the purpose described.

3. In an umbrella, the combination of aseries of ribs; a series of stretchers connected thereto and provided with spherical heads upon their inner ends a runner provided with a sleeve having a series of radial slots and spherical seats, said seats being adapted to receive and hold the heads formed upon the stretchers; a cup or disk provided with a channel in its upper face; a series of balls mounted in said channel immediately below the spherical heads of the stretchers; and means for maintaining said cup or disk in position.

at. In an umbrella, the combination ofa se ries of ribs; :1. series of stretchers connected thereto and provided with spherical heads upon theirinnerends; a runner provided with a sleeve at its upper end, said sleeve being provided with a series of radial slots 0 and sockets P adjacent thereto; agroove or channel Q formed in the under face of said sleeve; a cup or disk S provided with a groove or channel T; a series of balls R seated within said groove and the groove orchannel Q; and locking-nuts for holding said cup or disk in position.

In witness whereof I hereunto set my hand in the presence of two witnesses.
