UMBRELLA.

Speeication of Letters Patent.

Patented Oct. 6, 1914.

Application filed November 19, 1913. Serial No. 801,809.

T0 all whom it may concern Be it known that we, VAN DYKE CRUSER and AcoLri-i RosENBLUM, citizens of the United States, residing at 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, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in umbrellas; the object being to provide the stick of the umbrella with a yielding stop adjacent the top notch thereof, in order to allow the runner to pass over the same when the umbrella is subjected to an eXtreme pressure, whereby the umbrella can be turned inside out without injuring the saine, in any way.

Another and further object of the invention is to provide a yielding stop arranged in the path of an extension formed on the runner; said extension limiting the upward movement of the runner so as to prevent the stretchers and ribs from being broken when the umbrella is reversed.

We are aware that we are not the first in the art to provide an umbrella which is so constructed that the same may be reversed or turned inside out in order to prevent the same from being broken by the wind pressure. However, in constructions as heretofore employed, the stick was provided with a coil spring in order to allow the runner to move under extreme pressure and it has been found iii use, that an umbrella constructed in this manner, has many disadvantages.

1We have found that by providing the stick with a bowed spring forming a yielding stop, that an umbrella can be constructed much cheaper and will have many advantages over umbrellas of this character, now in use.

Other and further objects and advantages of the invention will be hereinafter Set forth and the novel features thereof defined by the appended claim.

ln the drawings Figure l, is an elevation of the stick, ribs and stretchers, showing the runner and a portion of the stick in section; and Fig. 2, is a similar view, showing the runner moved over the yielding stop so as to allow the ribs and stretchers to be reversed in such a manner that they will be prevented from becoming broken when the umbrella is turned inside out.

Like numerals of reference refer to like parts in the several figures of the drawing.

In the drawing, 1 indicates the stick which may be formed of the ordinary construction, having a top notch 2 secured thereto in which are pivotally mounted, ribs 3 and it will be seen that the notch is so constructed that the ribs are free to move in either direction in order to allow the umbrella to be set in a stretched position or reversed, as will be later described.

The stick is provided with a slot 4 spaced from the top notch communicating with a chamber 5 in which is mounted a bowed spring 6 which extends out through the slot 4L and is adapted to be engaged by the eX- tension 7 of a runner S slidably mounted upon the stick and held in its upper position, by a catch 9. The ruimer 8 carries a notch l0 in which are pivotally mounted stretchers 1l which are connected to the rib 3 in such a manner that they are free to swing in either direction so as to allow the ribs to turn as shown in Fig. Q, when the runner has passed over the stop formed by the bowed spring.

In Fig. 2, it will be seen that when the umbrella is reversed or turned inside out, the extension 7 of the runner 8 engages the top notch 2 in order to prevent the ribs and stretchers from becoming broken. vWhen the umbrella is moved into open position, the extension 7 of the ruimer S is engaged by the yielding stop so as to limit the movement thereof to such an extent that the umbrella will be held in a stretched position by the catch 9. When the umbrella is subjected to an extreme pressure, either by the movement of the runner past the yielding stop when raising the same or by an eX- treme wind pressure upon the inside of the same, the stop will yield so as to allow the ruimer to pass over the saine until it has engaged the top notch in which position, the ribs and stretchers will be reversed.

From the foregoing description, it will be seen that we have provided an umbrella which is so constructed that when the same is subjected to an unusual pressure, it can be turned inside out or reversed, without injury to the saine in the least and after it has been moved into that position by exerting a pressure upon the ribs from the outside, it can be moved back into its proper position. It will also be seen in the construction of umbrella as disclosed, that the ribs and stretchers are free to move upon their pivots in either direction and that after the runner has passed over the yielding Stop, it will be retarded from moving in a reverse direction by the action of the ribs and stretohers, so fis to prevent the same from beeoming strained. As the runner passes over the yielding stop, the movement of the seme is retarded by frietionel contziet therewith and the umbrella is allowed to be reversed Without injuring the same, :is is the ease *ith other constructions nonT in use.

We claim:

ln an umlinellsi9 the combination With a stick having i Chamber 'formed therein provided with :i slot, of ribs pivotally Carried by said stick, a runner slidzibly mounted upon Said stick having an extension, stretchere connecting said runner to seid ribs, and a bowed Spring arranged Within said chomber free to expend at each end having a, portion extending out through Said Slot in the path of travel of said runner, forming :i rietional stop for Said runner.

In testimony whereof We affix our signutures in presence of' tivo Witnesses.
