' SPECIFICATION forming part of Letters Patent N. 769,877, dated September 13, 1904.

Application iiled February 26, 1903. Serial No.' 145,239. (No model.)

T0 1J/Z whom, it may concern:

Be it known that I, PAUL SERGE-KIssLow, a citizen of the United States, and a resident of Portland, in the county of Multnomah and State of Oregon, have invented a new and useful Improvement in Umbrella Frames, of which-the following is a specification.

My invention has for its object to obtain a frame in which the ribs are detachably'secured to the notch and the runner, so as to be conveniently removed and replaced when requiring repair; also, to combine with the runner certain devices adapted to allow the umbrella to be opened and shut again by merely moving the runner up and down, the same contrivances further operating to secure the ends of ribs when the umbrella is shut and all the contrivancesto be simply but durably made. These features oi' my invention are fully hereinafter described. In said drawings, Figures 1 and 2 represen upper and lower portions of the umbrellastick and the corresponding `frame portions, Fig. l showing a section of my improved notch in which the upper ends of the ribs are removably hinged and Fig. 2 showing a section of my improved runner in which the inner ends of the stretchers are removably hinged. Fig. 3 is a partial elevation of the umbrella-stick and of my improved runner, the latter being partly in section, and the whole ligure illustrating how my improved runner operates to hold the umbrella shut. Fig. 4 is an inverted plan section on the line w m oi' the stern m of my runner, the screw n being removed. Figs. 5 and 6 are enlarged details illustrating the construction of the hinge ends of the ribs and braces, and Fig. 7 is a top view or plan of the sockets 0.

The letters designate the parts referred to. The construction of my umbrella with respect to the parts not illustrated is'oi' the usual form. -The notch consists of a cap provided with an annular recess e and annular concavity f, the notch being iiXedly secured to the stick t by means of a rivet d. Inserted in the cap b is a socket 0, cup-like in construction and provided with a series of radial slots g, adapted to receive the lat part o of the hinge ends of the ribs, the heads j of such hinge ends being contained in the hollow of the socket c. It will be observed that said hinge ends of the ribs are slightly curved, and the inner surface w of the slots g are beveled, so as to allow the ribs z' to come closely against the stick when the umbrella is closed. The socket c is removably secured in place by means of a staple z, inserted in a ho'le therefor made through the base oi' said socket and the stick a. f

The runner consists of a stem m, made with a socket-head on. The socket-head has radial slots or notches p, adapted to receive the inner ends of the stretchers k, also provided with hinge-heads j. The upper end of the stem m is threaded and provided with a screwcap n, made with an annular groove 0, adapted to receive .the rim of the socket-head m.

On the stem m is slidably mounted a sleeve Q. Said sleeve is made with a body portion of greater diameter than the stem m, a contracted upper end sliding on the stem m, and a socket-head t, at its lower end adapted to -be slipped over and to hold the free ends of the ribs when the umbrella-frame is closed. Within the sleeve Q is inserted a coil-spring of', holding the former in its normal position. In practice the sleeve g and said coil-spring are first placed on the stem m, and thereupon the lower end u of the latter is upset or iiared, so as to inclose and provide a bearing Jfor the lower end of the sleeve q to slide on. When the sleeve q is in its normal position, the flaring lower end of the stem m slightly projects. The flaring lower ends of the stem m and the sleeve g are respectively made with an inward taper or chami'er, so as to be adapted to depress and pass over the detaining-spring s on the stick one after the other.

rPhe runner is shown in Fig. 2 in the position it occupies when the umbrella is open. Its further upward movement is limited by the usual pin Z, and it is kheld against downward movement by resting on the usual spring s. The construction of the hinge ends of the stretche'rs are like those of the ribs. Such ends are inserted in the slots p, the heads ,7'

resting in the annular cavity of the socket m.

IOO

The parts operate as follows: Supposing the umbrella to be opened, by taking hold of the sleeve q of the runner in the act of shutting the umbrella the chamfered lower end of said sleeve will be brought against the spring s and depress the same to such an extent as to enter the chamfered lower end of the stem m. Continuing to pull the runner down will now cause the same to depress and pass over the spring s and the umbrella may be closed. The described operation may be done with the greatest ease. The spring at the lower end of the stick usually providedv to engage the runner and hold the umbrella shut is omitted by me. My umbrella-frame is held shut by means of the socket t being slipped over the ends of the ribs z', as illustrated in Fig. 3, the sleeve Q being first drawn down, the ends of all the ribs being neXt drawn closely together and the socket t slipped over them.

To open the umbrella, it is but necessary to pull the sleeve Q down to disengage the ends of the ribs and then to move the runner up past the spring s. The hinge-heads of the ribs and stretchers are made of a brass bar z,

provided with spherical heads j, and such heads are secured in place by compressing the rib ends c upon the same.

The hinge ends of my ribs and stretchers are strong and durable, for there are no eyes made in the same, which usually weakened these parts.

My improvement also prevents rusting of the hinge ends of the ribs. In the best umbrellas more or less rain will beat through the cover and run down the stick to the hinge ends of the ribs, causing the latter to rust. rIhe construction of my improved notch is such that whatever rain runs down on the cap b will run off again without having any chance of collecting in the hollow of the socket c.

In practice the recess e may be of lesser depth than shown. The rim b',however, should have ample depth to overlap the rim of the socket c, substantially as shown.

The concavity f of the cap e while not indispensable nevertheless is of material advantage, because it forms a better socket for the hinge-heads j of the ribs. If the surface f be made iiat, it would finally wear and conform itself to such hinge-heads, and by so doing abnormally enlarge the hollow containing such heads. It would also cause an uneven and iiat wear of such heads TheA concaved form of said surface, on the other han'd, distributes the wear and makes the parts last longer in good condition. To obtain a like benefit for the hinge-heads of the stretchers, the hollow e of the cap n is also concaved.

What I claim, and desire to secure by Letters Patent, is

l. A runner comprising in combination a stem m, and a longitudinally-movable springcontrolled sleeve on said stem; the said stem and said sleeve, each being made with a fiaring lower end, provided with an inward taper or chamfer, and adapted to depress the detaining-spring on the umbrella-stick, so that the runner may be drawn over the same, substantially as described.

f 2. A runner comprising a stem, m, a longitudinally-movable spring-controlled sleeve on said stem; said stem and said sleeve, each being made with a iiaring lower end provided with an inward taper or chamfer, and adapted to depress the detaining-spring on the umbrella-stick, so that the runner may be drawn over the same; and the lower end of said sleeve being further made with an integral sockethead, t, adapted to be slipped over and hold the free ends of the ribs when arranged together, substantially as described.

3. A runner comprising a stem, m, a longitudinallymovable sleeve, q, on said stem, which sleeve comprises a contracted upper end sliding on said stem, and a body of greater diameter than said stem; a coil-spring within the sleeve 'g holding the latter in its normal position; the lower end of said stem m being made with a bearing for the lower end of the sleeve q to slide on; said stem and said sleeve each being made with a flaring lower end provided with an inward taper or chamfer, and

adapted to depress the detaining-spring on the umbrella-stick, so that the runner may be drawn over the same; and the lower end of said sleeve being further made with an integral socket-head t, adapted to be slipped over and hold the free ends of the ribs when arranged together.

In testimony whereof I have hereunto affixed my signature, in the presence of two witnesses, this 31st day of January, 1903.

PAUL SERGE-KISSLOVV.
