IMPROVEMENT IN UMBRLLAS TheSchedu1e referred to in these Letters Patent and making part o the same.

To allwhom it may concern:

Be it known that I, DURWARD ADAMS, of Boston, in the county of Suffolk, and Stute of Massachusetts, have invented en Improvement in Umbrellas and Porasols, of' which the following is a full, clear, und exact description, reference being had to the accompanying drawings making part of this specification, in which- Figure 1 is acent-rul vertical section, representing my improvement applied to an umbrella when open and ready for use.

Figure 2 is :t central vert-ical section through a closed uinbrellzushowing the position or relation of my improvement thereto just previous to its being opened.

Figure 3 represents the position ofr my improvement .when the umbrellaI is to be set :iside und is not required for use. l

My invention hes for its object to provide an urnbreilu. or parasol which shall instantly spring open when required, by means ot' elastic rubber springs or bonds; and v My invention consists in the application of rubber springs leading from the stud' or handle, or asleeve thereon, to the breces or runner, or both, the springs being dstended whenthe umbrella. or parasol is closed, so that when the catch is pressed in, the runner will he drawn up andu the braces thrown out by the recoil of the springs, thereby opening the cover as required.

Toeneble others 'skilled in the art to understand und use my invention, I will proceed to describe the manner in which I have carried it out.

In the said drawings- A is the stuff or handle, B B the braces, C G the ribs, D the cover, E the runner, G the lower catch, and H the upper catch, ull constructed in e well-known manner.

I I are rubber springs, one end of each of which is secured by a ring or otherwise to one ofthe braces B, the opposite end of the spring being secured to e. sleeve,

K, surrounding the staff or handle A, the sleeve being heldin place by e, catch, a.

J is also a. rubber spring, one end of which is secured tothe sleeve'K, while its other end, instead of being secured to one of the braces, is connected dlrectly with the runner.

When the umbrella is closed, the springs I J are distended and held in this position (see fig. 2) by the lower catch G, which passes through the side of the runner E.

On pressing in the lower catchA the runner is released, when the recoil oi' the springs IJ willinstently draw it up and throw out the braces B B, thereby opening the umbrella without the necessity of' employing both hands, as heretofore.

To relieve the tension on the springs when the umbrellzt is to be set aside und is not required for immediste use, it is simply necessary to press in the catches H and a and slide the sleeve K over them, when it will be drawn down by the closing of the umbrella. without extending the springs.

Instead of employing a sliding sleeve, K, the springs muy beA secured directly to the handle, their opposite ends being secured to the braces and runner by means of hooks, which `rnny readily be detached when the umbrella is to be set aside.
