WILLIAM B. DIMON, OF PHILADELPHIA, PENNSYLVANIA.

UMBRELLA OR PARASOL.

SPECIFICATION forming part of Letters Patent No. 403,993, dated May 28, 1889.

Application filed December 18, 1888. Serial No. 293,960. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM B. DIMON, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Umbrellas or Parasols, of which the following is a full and complete specification, reference being had to the drawings annexed.

My invention relates to that class of umbrellas or parasols in which the lining is separate from the cover in the interior of the device. Amongits objects is to furnish a parasol or umbrella in which an ornamental effect is produced by the lining, and to enable a parasol or umbrella covered with black or dark colored material to be by means of the air between the cover and the lining a sufficient protection against the hottest sun.

It consists, essentially, of a lining shaped in such a manner that the lining itself without the aid of any ribs or other support will by the counteracting forces of its shape and the pressure of the runners and stretchers be held firm and taut in its desired shape.

Figure l is a view of a parasol or umbrella open and having the parts lined on the side of the stick next the observer removed, and showing the details of a two rib space on each side. Fig. 2 shows a section of the lining superposed upon a section of the cover, the sections being formed by passing planes through two adjacent ribs and the stick. Fig. 3 shows the transverse section of a secondary shape of the device; Fig. 4, the corresponding sections of the lining and cover formed in the same way as in Fig. 2. Fig. 5 is a perspective view of a device for receiving the lining at the top. All the parts in Figs. 1, 2, 3, and 4 are drawn mathematically correct.

Similar letters in Figs. 1 and 3 and 2 and 4 refer to similar parts.

M, Figs. 1, 3, and 5, is the stick.

N is a notch, to which the ribs l3 B B B are attached.

P is the runner.

C C C O are the stretchers, the lines I) b b b b b b b show the outline of the cover A, and the lines 0 c c c and c c c c the outline of the lining D when the parasol or umbrella is open.

A, Figs. 2 and 4, is a section of the cover; D, a section of the lining. a a a a show the curved outline of the cover-section. (Z d d d show the curved outlines of the lining-section. The curved outline shown in Figs. 2 and 4 is such as will produce the bell-shaped effect shown in Figs. 1 and 3, respectively. IVhere the parasol or umbrella is composed, as usual, of gores or sections sewed together, the section shown above will correspond to them, except thata strip to receive the stitches will then be added at the edges.

The cover A is made as usual and fastened to the ribs in the usual manner. The lining D is then fastened to the edge of the cover and attached to the ribs up to the point E, where it is desired that the bottom part of the bell or other shaped protuberance shall begin, and to the channeled ring N, placed between the top spring and the top notch, where the protuberance is to end. The channeled ring N may be placed on the barrel of the top notch. It need not be made of any material placed on the stick or top notch, but may be simply an annular channel in the stick or in the barrel of the top notch.

The shape of the protuberance (shown as the shape of the inside of a bell) may be changed according to the fancy of the maker by the ordinary skill of a workman, and de pends upon the shape of the lining. However, where a curve other than a convex one is desired it is ordinarily necessary to attach the lining at the part where it falls away most from the stick either directly to the ribs or indirectly to them by means of a cord, when virtually two protuberances, the second made in the same manner as the first, are produced.

In all cases the shape is determined in the following manner: The length of the lining from the point where it leaves the ribs and begins to form the ornamental shape to the place of attachment is the length of the line outlining the desired shape when the umbrella is open, (the line 0 c c c in Figs. 1 and 3,) and the circular measure of the lining at any given distance from its upper point of attachment is the circumference of a circle having a radius of the distance that point is de- IOC with them the portion of the liningv attached.

to them, and draw the whole lining in an outward direction, while, being of smaller circumference than the cover at any corresponding part, is drawn inward by its shape, and the two forces thus opposed hold the lining in the shape desired. Where it is desired that parts of the lining should bulge or be loose, the width should slightly increase at those parts. When the ornamental shape of the lining begins at a point below the junction of the ribs and the stretchers O O O 0 it is necessary that the stretchers pass through the lining to the ribs. To make the hole thus required as small as possible, the stretchers are made of greater length than the distance from the top of the ribs to the stretcher-joint, so that their motion in a direction parallel to the lining be as small as possible. shown most strongly in Fig. 3.

I am aware that parasol-linings partly detached from the ribs and attached to a travnot fastened directly to the stick, have previously been made. claim.

What Ido claim, and desire to secure by Letters Patent, is-

This lengthening is That, therefore, I-do not 1. A parasol or umbrella having the lining attached at the top immovably to the stick and at points nearer the bottom to the ribs or cover, and intermediately detached from both ribs and cover.

2. A parasol or umbrella lining attached at the top immovably to the stick and nearer .the

bottom to the ribs or cover, having the intermediate portion at all points of less width than the corresponding portion of the cover.

3. In an umbrella or parasol, an interior canopy having its convexity toward the handle formed by a lining having its gores of less width in its upper parts than the gores oi the cover, said lining-gores having their upper extremities turned upward toward the top notch and attached to a channeled ring, substantially as described.

4. In an umbrella or parasol, the combination of alining covering the stretcher-joint ofthe rib with a stretcher longer than the distance between the top of the rib and the stretcher-joint. 1

5. In an umbrella or parasol, the combination of a channeled ring between the top notch and top spring with a lining forming a canopy having the convexity toward the handle attached to said ring. and exerting a down- 1 ward pull thereon. eler moved along the stick by a spring, but
