A perni utation ring l() is mounted loosely upon thev stick 5, said ring having an inwardly extended annular wall 10a, the inner circular edge of which loosely engages the stick. The annular wall 10a is flat and is disposed a distance below the upper edge of the ring, an annular recess c being produced above said wall 10a. A radial bead d is formed on the exterior of the permutation ring l0, the edge of which is milled or otherwise roughened, and below the said ring is arranged a spring casing 10b, the interior diameter of which loosely receives the collar 9, the said casing being secured to the stick by a pin 10. A coil spring 11 is arranged within the spring casing, between the upper end thereof and the upper end of the collar 9. Above the permutation ring l0, a second permutation ring l2 is placed on the stick 5, the forni of which is similar to the upper portion of said ring l0.

Be it known that we, WILLIAM Lnoimin)v SPERRING and GUY REED PRIDE, both citizens of the United States, and residents of J ackl. sonville, in the county of Duval and State j of Florida, have invented a new and inproved Locking Device for Umbrellas and the Like, of which the following is a full, clear, and exact description.

The purpose of this invention is to provide novel means for locking the runner sleeve and attached stretcher rods of an umbrella or parasol in closed adjustment on the Reference is to be had to the accompanying drawings forming a part of this specificaltion, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a broken and partly sectional side view of the lower portion of an umbrella stick, a runner sleeve and stretcher rods in lowered adjustment on the stick, a spring latch carried by the stick and engaging within a slot in the runner sleeve, a slide bar. longitudinally adjustable in the stick for locking or releasing the spring latch, and a permutation lock carried by the stick and adapted by its adjustment for control of the slide bar; Fig. 2 is an enlarged longitudinal sectional view of an umbrella stick, and a partly sectional side view of details of the improved locking device mounted on said stick; and Fig. 3 is a transverse sectional view, substantially on the line 3 3 in Fig. l. The stick 5 of the umbrella, partially shown to illustrate the invention and its application, is tubular and cylindrical, having in complete form a suiiicient length for receiving the ribs and covering therefor as usual, these latter-named parts that are not necessary for the disclosure of the invention, being omitted from the drawings. Upon the stick a handle 5a is secured at the lower end thereof, and at a suitable point above central circular opening therein of such diameter as' permits the slidable insertion of the stick 5 therethrough and, as shown, the ring 12 is seated upon the ring 10. A third permutation ring 13, similar to the ring 12, in every respect, is loosely mounted upon the stick 5, the fiat inwardly extended bottom wall 13a of the permutation ring 13 seating on the upper edge of the ring 12, as shown in Fig. 2the wall 13a defining the depth of a recess c2 in the ring 13. The permutation rings 12 and 13, have circumferential beads and g respectively formed thereon, and these beads areL milled similarly to the bead d, to facilitate the rotation of the rings upon which they are formed.

Onl the stick 5, a washer plate 14 is fitted and disposed in loose contact with theupper edge of the upper permutation ring 13. A. collar 15 is mounted upon the stick 5 and seated upon the washer plate 14, the collar being secured in' place by a cross pin 71, or other means, thus loosely mounting` the permutation rings 10, 12, and 13 in place on the stick 5 between the top of the spring casing 10"` and the washer-plate 14 to allow individual rotation of either permutation ring` 10, 12 or 13;

Upon each ring 10, 12, 13, a plurality of indices are formed or secured, which may be either a series of numerals or of alphabetical characters, the latter being shown spaced apart thereon in Fig. 1. In each of the bottom walls 10, 12a and 13l of the respective permutation rings 10, 12,- 13, a radial slot z'V is formed, said slots being equal in width and length, and in the stick 5, within the permutation rings, a single elongated slot m is cut, having an equal width with that ofv the slots e' that may be disposed opposite said slot m.

A locking bar 16 is a completing detail of the improvement, and as clearly shown in Fig. 2, consists of a fiat strip of metal fitted loosely in the lower portion of the stick 5, and having three similar flat tongues n formed on one side edge thereof, which project through the slot m into the respective radial slots t', wherein said tongues are normally positioned. The locking bar 16 is laterally lextended at or near the lower end thereof, so as to have contact with the inner surface of the collar 9, whereon it is secured by means ,of a screw 0, as is shown in Fig. 2. The length of the locking bar 16, is proportioned so as to dispose the upper end port-ion of said bar below and near to the inner lower corner y? of the latch head 6a, when the locking device is not in use for retaining the umbrella closed. There is a rounded corner 11 formed on the upper end ofthe locking bar 16, which will engage with the corner p of the latch head 6a if the locking bar is moved upward a short distance, and this will prevent a depression of the latch head 6a. In

ordinary use, the spring 11 will by its ten` sion press the collar 9 and the attached locking bar 16 down until the lower end of the collar seats upon the handle 5, which will dispose the tongues n in the radial slots z', as is represented in Fio. 2.

When it is desired to lock the umbrella in close folded condition, assuming that the Vrunner' sleeve 7 is slid downward, so that the latch head 6a engages the slot a in the runner sleeve, the collar 9 is slid away from the handle 5EL by manipulation of the radial flange 9a, thus compressing the coiled spring 11 and imparting an upward sliding movement to the locking bar 16 thus disposing the tongues n in the annular recesses c, c', c2 iii the permutation rings 10, 12, 13, above the radial slots c' they normally occupy. The rings are now adjusted by turning them, so as to produce a selected combination of letters that may be word orany other associ ation of the letters on the rings, which will Y dispose the tongues@ on the end walls of the rings 10, 12, 13, away from the slots t'. upward movementV of the locking bar 16, due to the upward sliding movement of the collar 9, will enforce a locking engagement of the corner 1" with the corner y; on the latch head 6a, which will prevent a release of the runner sleeve 7 from the latch head and obviously secure the umbrella in folded condition. To the owner of the umbrella, who has set the combination of characters on the permutation rings, it will be the work of but few seconds `to turn the rings, so as to aline the radial slots z' with each other, and Vthus dispose them opposite the tongues a, which will adapt the tension of the spring 11 for effecting a downward sliding movement ofthe collar 9 into its normal position, and a retraction of the upper end of the locking bar 16 from the latch head 6, so that the umbrella may be raised and lowered as usual.

Having thus described our invention, we claim as new and desire to secure by Letters Patent: l
