PARASOL.

SPECE'IATIDN forming part of Letters Patent No. 296,318, dated April 8, 1884.

Application tiled October 29, 1883.

To all whom t may concern.'

Be it known that I, FRANK C. Dennis, a citizen of the United- States, residing at New York, in the county of New York and State oi N ew York, have invented certain new and useful Improvements in Parasols, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure l is a central vertical section of an umbrella or parasol to which my improvements have been applied. Fig. 2 is a central longitudinal section of the telescopic parasolstem extended, and Fig. 3 a similar view, ou an enlarged scale, ofthe parasol-stem closed. Fi g. L is a detail view oi' the top of the stem, showing the arrangementof the spring which holds the parasol open.

My invention relates to improvements in the construction of parasols or umbrellas, and is especially adapted for use in parasols or canopies of carriages.

Heretofore, in the construction of umbrellas or canopies, they have commonly been made with a single stem or handle, and have also been constructed with a sliding extension-handle, or with a stem which projected above and worked through the top of the umbrella.

My improvements consist of a stem made of two or more rods or tubes arranged to slide within or telescope each other, and with a springcatch arranged on the outside and above the parasol, whereby the latter may be lowered from the top. This construction also enables the parasol to be opened without the necessity I(which is usually the case with parasols' having short handles) or" inserting the hand between the braces of the parasol.

Referring to the drawings, A represents the telescopic stem ofthe parasol,composed oi' two or more sections, ci, arranged to slide within each other, so as to extend or collapse. In this instance I have shown the stem made in three sections, the outer one,or the one having the greatest diameter,constituting the top part of the stem, to which the collar b is attached.

The bows c converge and are fastened to the 5o the smallest diameter, carries the collar d at (No model.)

its outer end, to which are attached the braceribs c. This collar corresponds with what is called the runner l in an ordinaryT umbrella; but,instead of sliding upon the stem.it is rigidly attached to thetelescopic stem and moves therewith. A boss or button, f, projects below the collar d, upon which an upward press ure is exerted to raise the canopy. The inner or upper end of the lower sliding section, a, has a notch, y, or equivalent contrivance,which, when the parasol is raised, takes into a lug, Il, of any suitable construction form ed on a spring, i, and operated by a thumb-knob, 7s, which is pressed inwardly when it is desired to close the parasol.

Fig. 4 illustrates a sectional view of the para' sol head, showing the arrangement of spring i.

The top of the stem mayor may not be pro vided with the usual ornamental head.

Vhen my invention is used as a canopy for carriages,it is supported by a standard, B, in

the ordinary way. y

The lower or smaller section, a, may be either a solid rod or a cylindrical tube.

The arrangement of the telescopic sections may be reversed-that is, ,the largest tube,

`which in the drawings is shown at the top,

may be arranged for operation at the bottom of the stem, and the smallest one at the top. In this case the inner end of. the small rod is provided with the notch g, as in the first-described arrangement, and the lower or larger tube-section provided with the knob 7a and spring. This reversal of the stem-sections requires no change i-n their construction, they being simply turned end for end. By working the parasol either at the bottom or top of the stem, (the catch in both cases being outside the IOO from the notch in the lower telescopic section. The collar then acts as a stop to limit any further outward play of the spring.

Suitable means are provided to prevent the telescopic sections of the parasol-stem from coming apart. This may be accomplished in one Way by pins and slots Within the tube-sec tions. Y

Vhere but two sections are used in the stem, the pins or stops may be dispensed with, the bows and ribs of the parasol in that case preventing the disjointure of the stem.

-Having described my inventiomwhat I claim as new, and desire to secure by Letters Patent,

telescopic sections having-.a spring-catch for holding the umbrella open arranged at the top of the stem, whereby the catch may be operated from the outside to collapse the parasol, substantially as described.

4. In a parasol-stem composed of two or more sections, a spring-catch located at the top of the stem comprising the spring t', the lug h, and the thumb-piece k, arranged diainetrically opposite the spring, substantially as set forth.

5. rIhe spring-catch consisting of spring z', lug h, and thumb-piece 7c, arranged at the top of the stem, in combination with one of the telescopic sections having the notch or equivalent, substantially as described.

6. The combination of the spring i with collar l, the latter being mortised to limit the play of spring when thethumb-piece is operated to close the parasol, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

FRANK C. DENNIS.
