UMBRELLA.

SPECIFICATION forming part of Letters Patent No. 336,034, dated February 9, 1886.

Application filed Jul) 15, 1885. Serial No. 171,706.

To all whom it may concern.-

Be it known that I, CHARLES HENRY BUT- LIN, surgeon, a subject of the Queen of Great Britain and Ireland, and residing at Gamborne, in the county of Cornwall, England, have invented certain Improvements in Umbrellas, (for which I have obtained a patentin Great Britain, dated the 15th June, 1885, No. 7,273,) of which the following is a specification.

In Letters Patent of the United States No. 311,809, granted me February 3, 1885, is shown an arched carrier extending from side to side of a vehicle for the purpose of supporting the umbrella therein shown. The ferrule or slider of the umbrella to which the stretchers are attached is a divided or com pound one, part of the stretchers being attached to one and part to a second division thereof, in order that the ferrule or slider and the stretchers extending therefrom may be opened laterally to permit the umbrella to be attached to the arched carrier above the ferrule or slider, and as near the upper end of the stick as possible, the umbrella being thus supported sufficiently low to afford proper protection to the occupants of the vehicle.

Umbrellas of the necessary size for use as vehicle-tops or shelter are subject, especially when in motion, to a great strain of resisting air or wind, often sufficient to turn them inside out, which also sometimes happens to umbrellas of ordinary size carried in the hand against a breeze or high wind.

The object of my invention in this present instance, therefore, is to diminish to a mini-v mum the danger of such an accident, in fact, entirely obviating it, unless it bein the presence of very rare and exceptional gales. To accomplish this, I use an auxiliary set of stretch ers, extending from the ribs or from the stretchers at their point of junction to the ring carrying the inner ends of the ribs, or to an additional ring fixed upon the stick near to such ring for the ribs. These auxiliary stretchers may be used with each rib and its ordinary stretcher, or with only part thereof, forming braces for the ribs, the regular and auxiliary stretchers forming, when the umbrella is opened, a triangle whose base is the (No model.)

stick and whose apex is the point whereat they support the ribs, giving great resistance to any tendency of the umbrella to turn inside out under stress of wind. This will be better understood by reference to the drawings, wherein- Figure 1 is a view of the interior of an umbrella embodying my invention, while Fig. 2 is a view of such an umbrella-frame partially closed, the covering being removed.

In Fig. l the reference-letter G is the stick of an umbrella, of any desired length, near the upper end of which is secured the ring E, in which are pivoted the inner ends of the ribs B. Upon such stick moves the runner O, in which are pivoted the inner ends of the ordinary stretchers, A, whose outer ends are secured to and pivoted with the ribs B.

D are the additional or auxiliary stretchers, forming braces for the frame when the um brella is opened. At their outer end these auxiliary stretchers D are attached to the ribs B and stretchers A at the point of union of the latter. At their inner end they are pivoted in and secured to the ring E of the ribs B, or to a separate ring, F, attached to the stick closely beneath the ring E, so that their fixed inner pivotal points are in the immediate neighborhood of the pivotal points of the ribs they are intended to brace. Being thus arranged, the movement of the runner O in operating the ribs B and ordinary stretchers, A, for either opening or closing the umbrella also operates upon and places the auxiliary stretchers in proper position, thus obviating any extra care or operation for their use.

lVhen the umbrella is closed, the stretchers A and auxiliary stretchers G lie close to the stick in one plane, each set then forming practically a continuation of the other, so that the diameter or transverse bulk of the umbrella is not materially, if at all, increased, a neat appearance and compactness being secured thereby. As seen, the stick and the two sets of stretchers form a triangle, G A D, whose base is the stick and whose sides are the stretchers A D, strain upon the ribs being thus conveyed to the stick at two points of some distance apart, and each rib being strengthened and braced at such two points.

This construction is applicable to all sizes and forms of umbrellas, and with the same advantages, the term umbrella being used to include all such forms and sizes irrespective of technical namessuch as sunshades, 850.

In Fig. 2, however, I have shown the invention applied to an umbrella having the divided ferrule or slide of my patent herein before referred to, in order that the stick of the umbrella may be secured to an umbrella carrier or arch at a point very near to E F, so as to bring the umbrella as closely down as desired to the occupants of a vehicle for securing the full protection of the umbrella. The auxiliary stretchers need not necessarily be applied to each rib in all cases, as in some instances a few such auxiliary stretchers, or such used
