'o a/ZZ whom t may concern.-

' Be it known that we, HENRY BOLLAOK and GEORGES MEYER, citizens of the French Bepublic, residing at Paris, in the Department of the Seine, in the Republic of France, have invented a new and useful Improvement in Umbrellas, (for which we have obtained Letters .Patent iii-France, No. 150,719, bearing date of August 19, 1882, and provisional protection in Great Britain, No. 5,187, dated October 31, 1882,) of which the following is a specification.

This invention relates to improvements in an umbrella, whereby it is made to open automatically, aetuatedbya spiral orhelical spring, which expands or distends when it is desired to open the umbrella for use, remains compressed in the socket of the slider or runner while the umbrella is closed, and is held in this position by a kind of spring clasp or catch set in the handle, or by a suitably-arranged cup or tip-fastener with or without spring. The spiral or helical spring is coniined between the upper part of the socket of the runner and a second runner, to which are attached as many tension-rods of thin metal wire as there are hollow stretehers, corresponding to the ribs receiving the cover, which is made of any suitable material. The upper part of the socket of the main slider or ruimer, or the lower part of the nut or collar to which the ribsare joined, is provided with a washer of indiaerubber or other elastic material to deaden the shock arising from the expansion of the spiral spring, which is particularly felt upon the nut or collar of the ribs. Another spiral spring may, if desired, be placed between the second slider or runner and the piece into which penetratesfthe spring-catch of the handle when this catch is used, also for the purpose of deadbeing completely compressed, and Fig. 3 is a similar section, but showing the use of a tipcup fastening.

A is the nut or collar, to which are attached the ribs a; and C is the slider or runner, to which are attached the stretchers f, hollow or U- shaped in section. This runner is extended in form of a socket, c, furnished at its upper part with an india-rubb er washer, c', Fig. 2, intended to deaden the shock or blow against the nut or collar when the umbrella is opened. This washer, as above stated, may be placed immediately under the collar to produce the same effect.

Within the socket c is placed the spiral spring R, encircling the tube D, soldered to the said socket, which spring has its fulcrum or bearings under the washer x, and also upon the second runner, E, to which are attached the tension-rods t, the outer ends of which are attached to the strctchers f. The lower part, d, of the tube D is screw-threaded on the outside to receive the piece B, into which takes the spring-catch o, set in the handle M.

m is the stick or rod, which may be of metal or of wood, passing through the tube D.

Upon Fig. 3 we have shownl in section the tube D, the lower part of which is tapped at d to receive the tube I), which is enveloped by the tip-cup G, intended to receive the ends of the ribs a..

o' is the spiral spring, which constantly brings back the cup G upon the ribs when the umbrella is closed, and which is compressed when the cup is drawn backward, in order that the umbrella may open of itself, actuated by the spring B.

We would here observe that a spiral spring, R, may be, if desired, placed between the bot- Y tom ofthe second runner, E, and the upper part of the socket of the piece B, for the purpose of lessening or deadening the shock produced in opening the umbrella.

In the position shown in dotted lines atFig. 1 the umbrella is closed, the tension-rods t lying snugly within the hollow ribs f, and the catch o taking into the piece B, or the spring tip-cup keeping the whole in place, the spring R being completely compressed, as shown, Figs. 2 and 3.

By pressing Aupon the part oof the catch or IOO by pulling back the cup, the piece B or the ribs are released, and the spring R,in distending, eauses the opening of the umbrella, the washer c and the spring R deadening the shock or concussion.

We do not desire to claim, broadly, the oombination with an umbrella, of a spring to automatically open the umbrella; but

XVe claim as our inventionl. The combination of the ribs and stretchers of an umbrella with a runner, G, to which the stretchers are connected, a runner, E, and tension-rods, and a spiral spring, R, interposed between the two runners, substantially as set forth.

2. The combination of the ribs and stretchers of an umbrella and a sliding tube, D, with
