Specification of Letters Patent.

Application filed June 28, 19.67.

Patented Apr. 25, 1911. Serial No. 381,254.

To all 'whom it may concern:

Be it known that l, CHARLES F. BURTON, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful improvement in Umbrellas, and vdeclare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to umbrellas.

lt has for its object an improved umbrella intended and adapted to provide a more complete covering with the same or reduced spread of the frame, and also intended to provide a structure in which the user can bring the umbrella more directly over his head, thereby protecting equally the two sides and equally the front and the back of the user. These objects are accomplished by the structure shown in the drawings, in which Figure 1, is an elevation of the frame in the position it assumes when fully spread. Fig. 2, is a detail of the joint at the meeting of the two rods. Fig. 8, is a detail of the hinge joint between the two short ribs. Fig.

4, is a detail of a hinge joint between the full length ribs 6 and l26 of Fig. 1.

The structure which embodies this invention, consists essentially of two comparatively small umbrellas, whose rods are pivotally connected at their handle end, and each rod has at its canopy end a notched ring, which is central to a set of radiating ribs; the ribs of each set are actuated by braces or stretchers, which are pivoted to and radiate from a runner on the same rod. ln order that the covering may be easily applied to this duplex frame, and in order that it may be more shapely in appearance, I prefer to use eight ribs in each section of the frame, and I prefer to bring three ribs of each section of the frame into intimate connection with the corresponding three ribs of the companion section of the frame. Of these three ribs, the middle one in each set is shortened, so that t-he two sections of the frame meet along what might be considered a great circle, were these structures a complete sphere, and this great circle is in a plane passing midway between the two rods through the joint which unites them, and at a right angle to the plane which the rods themselves occupy.

1 indicates the rod of one of the small umbrellas, and 2 indicates the rod of the other small umbrella. The frame mounted on rod 1, is of ordinary construct-ion, comprising preferably eight ribs, of which ribs 6, 7, 8, 9 and 11 appear in the drawing; a rib corresponding to 6 is supposed to be directly behind the rib 6, and a rib corresponding to rib 9, is supposed to be directly behind the rib 9. Each rib is provided with its proper brace 6", 7", 8", 9b, and the braces are pivoted to a runner 12 of ordinary construction; the ribs themselves are pivoted to a top notch ring 13 of ordinary construction. The frame mounted on rod 2, is of exactly similar construction, being composed of ribs 28, 29, 26 and 27, braces 28h, 29h, 2Gb, and 27h, top notch ring 13EL and runner 12a. The ribs 6 and 26 are left their regular length and are joined together by a link 16. Ribs 7 and 27 are preferably shortened as hereinbefore stated and are connected by a double pivoted link 17 shown in detail in Fig. 4, which link itself is provided with a thread hole 18 midway its length. The link 17 is so narrow in its vertical width, (as shown in Fig. 4), that the rib is not received entirely into the groove of the link, which is made as a bent or grooved two walled link rather than of two separate pieces. The purpose of the narrow construction of thislink is that the rib may hold the cloth of the cover off from the edge of the link when the canopy is stretched. The under web of the link serves as a stop to prevent the ribs 7, 27, from passing beyond a straight line. The two rods 1 and 2 are pivoted together by a pivot 19 which engages through the end of the rods and in order that the two rods may be closed to a parallel condition, each end is slightly bent between the pivot point and the main part of the rod. For practical use, the umbrella may, if desired, stop at this point, but it is sometimes desirable, and I have preferred to add a handle 20, which terminates at the upper end in a fork 21, through the branches of which engage the 'ends of the pivot 19. The cavity between the members of the fork serves to conne the ends of the rods and the bottom of the cavity serves as a stop to prevent the handle 2O from swinging with respect to the rods when the sticks are spread to the position shown in Fig. 1. It is not necessary to make provision for a wider divergence or a greater angle between the two rods than that which they assume when the trames are fully spread, for although the ribs 7 and 27 in both opening and closing will describe an yarc slightly beyond the line between the pivot 17 and 19, in the drawing of Fig. 1; the spring of the ribs is sufficient to allow them to make the travel. The cover stretched over the frames thus constructed Vis similar to the ordinary covering, most of the sections of the cover being of regulation shape. The section of the cover which fills the space over ribs 7 and 27, and between Y ribs 6 and 26, and their companion ribs, is a diamond shaped piece, and a nearly triangular gore lills the space between pivot 164 and the ends of the ribs 11 and 11a.

lVith ribs sixteen inches in length an umbrella constructed according to this invention will cover the head and drop below the shoulder line at each side of the body,

, and at the same time will extend from front the handle removed, it will close into a spacev only slightly longer than the length of the rib used in constructing it, and with a sixteen inch rib, the entire structureroccupies only about eighteen inches. The tips d, d, are shown as made short for the same reason,

' but the llength of the tip is immaterial to the mechanical construction of the frame.

The details of the several pivotal connections between the parts may be greatly varied, while still retaining the main feature of novelty, which consists in so uniting the frames of two small umbrellas that they shall sustain and stretch a single cover, shall properly brace each other to hold the frame expanded, and hold the canopy end of the rod spread and the rods and ribs firm in their spread condition.

What I claim is 1. An umbrella, having in combination a pair of frames, each frame comprising rods, ribs and braces of ordinary construction, a

rib vot' one frame being joined to a rib of the second frame and the rods being connected, substantially as described.

6. An umbrella, having in combination a pair of frames, having a shortened rib of one frame pivotally connected by a double pivot link to a shortened rib of the other frame, and a pair of full length ribs at each side of the shortened ribs pivotally connected at their meeting points, substantially as described.
