UMBRELLA, eee.

SPECIFICATION forming part of Letters Patent No; 356,479, dated January 25, 1887.

Application filed May 25. 1885. Serial No. 166,582. (No model.) Patented in Germany December 28, 1884, No. 34,061; in Belgium April 11, 1885, No. 68,492; in Ita1yAnril15,1885, No. 18,205; in England April 24, 1885, No. 5,125; -in France June 13, 1885, No. 169,536; and in Austria-Hungary July 1li, 1885, No.15,063 and No. 37,187.

To all whom, it may concern:

Be it-known that I, CARL ALBERT Max KREMER, of Leipsic, in the Kingdom of Saxony, Germany, have invented a new and useful Improvement in Umbrellas and Parasols, (for which l have obtained patents as follows: Germany, No. 34,061, dated December 28, 1884; Great Britain, No. 5,125, of April 24,1885; Austria-Hungary, No. 15,063 and N o. 37 ,187, of July 16, 1885; France, No. 169,536, of June 18, 1885 Belgium, No. 68,492, of April 1l, 1885; Italy, No. 18,205, of April 15, 1885,) or" which the following is a specification.

In theaccompanying drawings the umbrellastick embodying the present invention is represented in Figures 1 to 5, Fig. 1 being a lou- Agitudinal section (partly broken off) showing the mechanism in the extended position, while Fig. 2 shows the mechanism closed. The remaiuing figures illustrate details.

The eontrivance can be applied to any umbrella, which can then be held opened or shut with one hand, and also secured when open or shut.

The mechanism consists, principally, ofthe rods c and b and the bent bar d, one extremity of the rod a being hinged onto a ring, o, fixed tov the stick, and the corresponding extremity of b to a ring, g, sliding on the stick. The other extremities of a and b, aswell as the extremities of the bar d, are pivoted together. Moreover, the mechanism comprises the spindle s, sliding inside the hollow umbrella-stick iS, and connected'at one end with the bar d and the spiral spring f, at the other with the link e and the lever k. n

As shown by Fig. 1, the rods a and b form a quadrilateral stretched by the bar d, which represents a diagonal of the same. y rilateral can be made to lie dat along the stick by pushing the spindle s against the crownring or top notch, h, the bent ends of the bar d following this movement, while the slide q is moved downward toward the handle G, as shown in Fig. 2. The, spindle s is moved by turning the lever la around the pin t', fixed to the handle of the stick.

An umbrella provided with such a stick, if held with the point downward, can be opened The quadwith one hand by means of its own weight, aided by the spiral spring f, 'and by drawing the spindle s toward the handle G by means of the lever 7c. When the umbrella is thus open, the struts or ties a b form the quadrilateral shown in Fig. 1, and it is secured in this position by drawing the ends ofthe bar d, connected with the spindle s, slightly toward the handle G by means of the lever la. The umbrella is released from this position for the purpose of being closed by pushing back the ends of the bar d, and the umbrella is also closed, when its point is held upward, by its own weight, and by pushing the spindle s toward the top notch, h, by means of the lever k. When the umbrella is being closed, the helical springf, which tends to open the umbrella, is compressed. When closed, the umbrella is secured by pushing the lever k so far into the handle G that the elastic pin r, guided on the handleG and actuated by aspring, projects into the groove in front of the rim z of the button on the lever k, as shown in Fig. 2, whereby thelever k is secured and the umbrella kept closed. Lastly, Fig. 5 shows a lever, k', which is a slight modification of k, and also a second ,contrivance for securing the umbrella when closed, consisting of the hook e on the lever k, and the bent pin r', actuated by a spring. In this case the umbrella when closed is secured, in the same way as already described, by pressing the lever k into the handle G, so that the hook 2^ catches under the pin i", and the frame is released by withdrawing the lever la at the proper time, whereby the hook is disengaged from the pin.

What I claim is- 1. An appliance for automatically opening and closing umbrellas, comprising an axiallyperforated umbrella-stick, S, a movable spindle, s, situated in the interior of the umbrellastick, a spring, f, adapted to press the spindle downward, rods a ci b b, connected so as to form a variable quadrilateral, the inner ends of the upper rods being rigidly connected with the stick, while the inner ends of the lower rods, b b, are connected with the movable sleeve or runner holding the stretchers of the umbrella-frame, a pair of rods, d, hinged in the` center to the spindle s and forming at diagonal of the said qnadrilaterztl, an operating-lever, la, hinged to the lower part of the stick, and a link, Z, connecting the lower end of the spin- 5 dle s With the outer end of the lever 7c, substantially as described.

2. The contrivanee fol' operating the meehanisni and for securing the umbrella when closed, comprising a spring-pressed pin guided Io on the umbrellastiek and a button hinged to thejoint of the operating-lever and link and adapted to form a catch for the said pin, sul stantially as described.

In testimony whereof I have signed this specication in the presence of two snbserb- 15 ing Witnesses.

CARL ALBERT MAX KREMER.
