CANE-UMBRELLA.

SPECIFICATION forming part of Letters Patent No. 386,078, dated July 10, 1888. l

Application filed January 5, 1887.

To @ZZ whom it may concern.:

Be it known that I, JOHN MoCoRiirIoK, a resident of W'ashington, in the District of Columbia, have invented certain new and useful Improvements in Cane-Umbrellas; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which 1t pertains to make and use the same.

My invention relates to improvements in cane-umbrellas, and is fully described and eX- plained in .this specification, and shown in the accompanying drawings, in which# Figure l is a longitudinal central section of the frame of my umbrella. Fig. 2 is a similar section, on a larger scale, of the end of the umbrella shaft and the tip attached thereto. Fig. 3 1s a view, partly in section and partly in elevation, showing the connection of a rib and brace of the frame.-` Fig. 4 is a central longitudinal section of a portion of the shaft and the runner mounted thereon. Fig. 5 is a crosssection through the shaft, the ribs, and the braces,the plane of section passing through thejoints which connect the ribs and braces. Flg. 6 is a side elevation of the complete caneumbrella, the umbrella being inclosed in a sectional shell in the manner hereinafter set forth, and Fig. 7 is a longitudinal section of a y number of the sections making up the shell.

In these views, A is a tapering corrugated shaft, of any suitable material, but preferably of hard rubber, and A is a stiffening rod or tube of metal lying within the shaft and projecting beyond the smaller end thereof. Upon the tube A', and in contact with the end of the shaft A, is fastened a thimble, B, formed with the usual annular groove, b, adapted to receive the wire which secures the ribs of the frame to the shaft, and also provided with a second annular groove, b', intended to receive the edge of the material with which the umbrella is covered. A tip, A, having a daring mouth which fits over the covering of the umbrella, is mounted on the tube above the thimble B, and the thimble and tip are both fastened to the tube by means of a rivet, r.

A soft-rubber tip, a, is set in the end of the tip A, and secured therein by an ordinary metal ring, a', and a suitable rivet. A run- Seral No. 223,424. (No model.)

ner, D, slides freely on the shaft A, and is provided with a latch, d, actuated by a spring, d', and provided with an inwardly-extending lug adapted to enter suitable notches, d", on the shaft, and thus to secure the runner in any desired position thereon. The catch d lies in one of the grooves of the shaft, in which it slides freely, and thus prevents rotation of the runner on the shaft. A series of ribs, C, forming the main frame of the umbrella, is joined to the shaft by means of a wire lying in the groove b of the thimble B, and ribs O, pivoted at their lower ends to the runner and at their upper ends, by means of pivots p, to the centers of the corresponding ribs, complete the frame. -Each of the ribs C is a solid bar, and each of the braces C is a corrugated bar, U shaped in cross-section, the closed edge of the corrugated bar being inward and the open edge outward. The joint between each brace and the corresponding rib is formed by flattening the rib, cutting away the closed edge of the corrugated brace for a sufficient distance at the end thereof, placing the separated ends of the brace on opposite sides of the flattened portion of the rib, and passing a rivet through the center of the joint thus formed. The rivet is approximately in the central line of the rib,and when the frame is closed and the runner is at its lowest possible position on the shaft the lower half of each of the ribs lies wholly within the corresponding brace. The braces are so placed on the runner and the ribs are so spaced on the thimble B that when the frame is closed the upper part ofeaoh rib and the whole of the corresponding brace lie in one of the grooves of the shaft, and since the lower half of each rib lies within the brace the entire frame lies within the grooves of the shaft, and, in fact, l

the diameter of the entire frame when closed is no greater than the greatest diameter of the shaft itself.

A portion of the metal forming the closed edge of each of the braces O is loosened at its edges near the joint with the rib, but is still connected with the brace at one end, though free at the other, and this partially-detached strip of metal forms a tongue, o, which affords a yielding spring-connection of the brace and 1o( rib when the frame is expandel, as shown in inthe formation of a canenmbrella, do not Fig. 3.

To convert the umbrella into a cane, I nclose it in a telescopic cover made up of sec? tions E E E E, preferably of cellnloid,or hard rubber or other similarnlaterial. Each ofthe sections is a short cylinder, and the successive cylinders from the tip toward the base or handle of the umbrella-shaft gradually in crease in diameter, their relative sizes being such that each section may be inclosed in the larger one next succeeding it, and the entire shell may be telescoped until itis wholly contained within thelargest section, E. Ahollow handle, A", having adetachable cap, AW', is fastened to the larger end or base of the shaft A, and serves as a receptacle for the entire shell when removed from the umbrella and telescoped, as described. Each of the sections of the shell has at its upper or tip end a double annular flange, e e', and at its opposite end is made daring, and is provided with an external flange, e. The inner iange, e', of each section engages with the outerange, e, of the section within it when the shell is fully extended, t-hus preventing accidental separation of the parts through the extension of the shell, and the flange e of each section strikes the ilange c of the next larger section when the shell is telescoped. and thus prevents accidental separation of the parts through the teleseoping of the shell. The flaring month of each of the sections prevents abrasion of the cover when the shell is slipped on or of the umbrella, and the other peculiarities of form of the sections are necessary to the satisfactory operation of the shell.

Vhile the frame shown and described is peculiarly adapted to use with an inelosing-shell limit my invention, with relation to the frame itself, to its combination with a shell like the one shown and described, or any other form, since the improvements in the frame are applicable to any umbrella.

Having now described and explained my invention, what I claim as new, and desire to se cure by Letters Patent, is-

l. The combination ofthe shaftA,thethi|n ble B, the runner D, the ribs C, pivoted to the thimble, and the braces C', U-shapcd in crossseetion and pivoted to the runner with their open edges outward, each of said braces being provided at its outer end with ears which clasp the corresponding rib, C, and with the integrally-formed tongue c,and connected with the rib by means of the pivot P, passing through the ears and through the rib at a point approximately in its central line.

2. In an umbrella, the combination, with a suitable shaft, of a runner sliding thereon and having its inner surface longitudinally recessed, a latch pivoted in said recess and having one of its ends turned inward in a lng adapted to enter corresponding notches in the shaft and its opposite end turned outward to form a pin for operating it, and a spring interposed between the latch and the outer snrface ofthe runner and pressing inward the inwardly-turned end of the latch, substantially as and for the purpose set forth.

In testimony whereof I have signed this Specification in thepresence of two subscribing witnesses.

JOHN MCCORMICK. Vitnesses:

M. A. BALLINGER, GEO. P. WHITTLESEY.
