Abstract: 14,852. Mills, B. J. B., [Ely, C. H., and Danser, J. W.]. June 30. Folding, telescopic, and like umbrellas.-Relates to the invention described in Specification No. 9417, A.D. 1900, and consists of a locking- device for the telescoping ribs of, and an improved folding stick for, a folding umbrella. The parts can be manufactured by means of dies and presses without soldering or brazing. The stick A, Fig. 14, is composed of two tubular sections, the relative rotation of which is prevented by a tenon 26 in the upper part engaging a notch 27 in the lower. A rod 28 is rigidly secured to and projects from the upper section, and is secured to a rod 30 which slides in the lower section by means of a link 32 of sufficient length to allow the folded cover space between the folded parts of the stick. The slots 31 in the rods 28, 30 are made deep in order that the ends of the rods may come close together when the stick sections are in line. A small rod 33 connects the rod 30 to a block 34 attached by pins through a slot in the stick to a sleeve 35, which slides on the staff and has a screw-threaded upper end, which engages a nut 36 on a sleeve 37 attached to the handle 38. By unscrewing this nut and withdrawing the handle, the lower section of the staff can be pulled from over the link 32 and the stick can be folded. The tip B, Fig. 3, is removably secured to the stick by a spring latch 1 having a tip 2 which engages a hole in the staff. The telescoping ribs are each made in two sections C, D, the latter or outer section sliding over the former or inner section. The sleeve H, which is attached to the inner rib section C by the depressions 15, Fig. 7, in the latter, completely encloses the outer rib section D, which is attached to a sleeve I by bending the end clips 8 formed on the latter into grooves 9 formed in the rib section. The inwardly-turned edges 10 on the sleeve guide the sections in their sliding movement. Two ears 11, with holes 13 and slots 14 for the stretcher attachment, and a loop 12 for the attachment of the cover are also provided. The stretchers E, Figs. 1, 3, and 5, which are pivoted to the runner G have forks J fastened to their upper ends by crimping the stretcher, as shown at 17, and by bending over the fork, as shown at 16, Fig. 5. The pin 18 in the fork pivotally joins the stretcher to the sleeve I and serves as a pivot also for the locking-dog K, Fig. 6, the cam-slot 20 in the latter standing obliquely to the slots 14 in the sleeve. Locking- rods F, Figs. 1, 3, and 5, which are pivoted at their lower end to a sleeve 4, Fig. 1, carried on the runner and moved thereon by a nut 5, slide inside the stretchers and have each at their forked upper ends a pin 21 which engages both the slots 14, 20 in the corresponding sleeve and dog. By screwing the nut 5, the locking-head 19 of the dog K is moved into engagement with or away from the locking-block L, which is secured to the inner rib section C by crimping the latter,. as shown at 23, Fig. 7. Fig. 1 shows the rib extended and the dog locking the rib sections. Fig. 3 shows the unlocked rib partly telescoped. Each locking-rod is guided in its corresponding stretcher by a band 24 secured to the latter, and a band 25 may be secured to one or more of the inner rib sections to limit the movement of the outer rib sections. The sleeves H, I and the fork J are made from sheet-metal punchings, and the ribs, stretchers, and locking-rods are made of U-shape or "paragon" construction.
