as to resist any ordinary effort to force the ribs in an outward direction, as occurs when the top of the umbrella is in popular phraseology turned inside out and the top of the umbrella assumes a convex relation relative to the user instead of its normal concave position. lVhcn the umbrella is closed, the flexible cords or stays pass back again to their normal position and the coil E rests once more against the spri ng-catch a', the resilience of the spring-coil being sufiicient to take up the slack of the cords and to hold the same taut again, and as the said cords are folded up within the umbrella-top our device is now entirely invisible.

Obviously as many of our exible cords may be used in an umbrella as may be desired, although we prefer to attach our device to every alternate rib, sufcient resistance being thereby given to the umbrella-frame to withstand any injury that would otherwise be caused by the ribs being bent or broken b v wind-storms, and as our device occupies no appreciable room within the umbrella-frame the said umbrella may be rolled up as tightly as if our invention was not in use in connection therewith.

As it is evident that many changes in the form, construction, proportion, and relative arrangement of parts might be resorted to without departing from the spirit and scope of our invention, we would have it understood that we do not restrict ourselves to the par ticular construction and arrangement of parts shown and described, but that such changes and equivalents maybe substituted therefor, and that TWhat we claim as our invention is l. An umbrella-frame comprising a stick or rod, a runner, ribs, and stretchers intermediate of the runner and the ribs to hold the opened ribs in an outward position, and means, extending from the said rod or stick to the runner and from thence to a point intermediate of the stretcher-joint and the tip of the rib, to hold the said opened rib from being forced in an abnormal outward direction.

2. An umbrella-frame comprising a stick or rod, a runner, ribs, and stretchers intermediate of the runner and the ribs to hold the opened ribs in an outward position, and 'flexible means held in a movable relation to the stick orrod and extending from the said stick to the runner and from thence to a point intermediate of the stretcher-joint and the tip of the rib to hold the `said opened rib from being forced in an abnormal outward direction.

3. An umbrella-frame comprising a stick or rod, a runner, ribs, and stretchers intermediate of the runner and the ribs to hold the opened ribs in an outward position, and means, consisting of a spring and a iieXible part running from the stick or rod to the runner and from thence to a point intermediate of the stretcher-joint and the tip of the rib, to hold the said opened rib from being forced in an abnormal outward direction and constructed and arranged to become folded up within the 'umbrella when closed.

et. In an umbrella, a frame, comprising a stick or rod, ribs, and stretchers intermediate of the runners and the ribs, and spring-controlled flexible means running from the said spring to a point intermediate of the stretcherjoint and the tip of the rib to prevent the said rib from being' forced in an outward direction, and a casing or tube to inclose and contain the said sliiring-controlled flexible means.

In an umbrella, a frame, comprising a stick or rod, ribs, and stretchers intermediate of the runners and the ribs, a spring-coil mounted around the rod, and a series of flexible cords extending from the said spring to points intermediate of the stretcher-joint and the tips of the ribs.

1n testimony of the foregoing specification we do hereby sign the same, in the city of New York, county and State of New York, this 2d day of April, 1904.
