UMBRELLA.

Specification of Letters Patent.

Patented July 19, 1921.

Application filed December 4, 19%). Serial No. 428,333.

To all whom it may concern:

Be it known that I, JERRY M. LEWIS, a citizen of the United States, residing at Little Rock, in the county of Pulaski and State of Arkansas, have invented a new and useful Umbrella, of which the following is a specification.

This invention relates to umbrellas and the like, one of its objects being to provide means whereby the sliding sleeve or ferrule of the umbrella can be looked against movement, thereby to prevent the umbrella from being opened unless a key, provided for that purpose is used to unlock the sleeve.

Another object is to provide locking mechanism which is simple and compact in construction and which does not detract from the appearance of the structure.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings- Figure 1 is a view partly in section'and partly in elevation of a portion of an umbrella having the present improvements combined therewith.

Fig. 2 is a section on line 22, Fig. 1.

Fig. 3 is an end view of the handle of the umbrella.

Referring to the figures by characters of reference 1 designates the tubular stem or rod of the umbrella and slidably mounted thereon is a runner 2 having a slotted flange 3 to which the stretchers 4 of the umbrella ribs are connected in the" usual manner or, if preferred, by means of ball and socket joints such as shown at 5. The runner 2 is provided with a slot 6, as ordinarily, for the reception of a pivoted tongue 7 mounted within the stem or rod 1 and adapted normally to project through a slot 8 in said stem or rod.

One end of the stem or rod 1 projects into the shank 9 of a handle 10, said shank being provided with a bore 11 extending throughout the length thereof. The rod or stem 1 can be attached to the shank 9 in any manner desired, as by means of a tongue 12 formed integral with the rod or stem and fastened to the handle shank 9 by means of screws 13 or the like.

The outer end of the bore 11 has a lock casing 14 secured therein by means of a face plate 15 as shown particularly in Fig. 3 and the lock mechanism, which can be of any construction desired, includes as a portion thereof a stem 16 adapted to be rotated when the proper key, A is inserted into the casing 14. To this stem 16 is secured one end of a rod 17 the other end of which merges into a spiral 18 engaging a cross pin 19 mounted within the tubular rod or stem 1. The spiral 18, in turn, merges into a rod 20 which extends longitudinally within the stem or rod 1 and carries at its free end a wedging block or head 21.

When it is desired to lock the umbrella so that the same cannot be used, the runner 2 is slid along the rod 1 until the tongue 7 springs into the slot 6 as ordinarily, thus holding the runner in position with the umbrella folded. The key A is then inserted into the lock casing 14 and rotated. This re quires the rod 17 to rotate and as the spiral 18 is formed of spring metal it will, when rotated, be fed longitudinally by the rod 17 and partly expanded, thus to thrust the head or block 21 under the tongue 7 and prevent the tongue from being pushed inwardly. By turning the key in the opposite direction the spiral 18 will be rotated so as to feed downwardly upon the pin 19, thus relieving the spiral of its tension and restoring the parts to normal position.

What is claimed is 1. The combination with the tubular rod of an umbrella or the like, a tongue movably mounted therein and normally projecting therefrom, and a runner slidably mounted on the rod and movable into engagement with the tongue. of a handle, a resilient spiral mounted for rotation within the tubular rod, means in the handle and engaging the spiral for feeding the same longitudinally when rotated, a wedging head connected to the spiral and movable into and out of engagement with the tongue, and key operated means at one end of the handle for actuating the spiral.

2. The combination with the tubular rod of an umbrella or the like, a tongue movably mounted therein and normally projecting therefrom, and a runner slidable on the spiral and direct the head into or out of en gagement with the tongue.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.

JERRY M. LEWIS.
