LOOK FOR UMBRELLA-STANDS.

SPECIFICATION forming part of Letters Patent No. 739,180, dated September 15, 1903. Application filed January 3, 1903- Serial No. 137,710. (No model.)

To all whom it may concern:

Be it known that I, WILHELM HOLL, a subject of the German Emperor, residing at Winterthur, Switzerland, have invented certain new and useful Improvements in Looks for Umbrella-Stands, of which the following is a specification.

The subject of the present invention is a lock for umbrella-stands which renders impossible the unauthorized removal of the umbrella, walking-stick, or the like placed therein by securing the umbrella in its place by the arm of an angle-lever held in the looking position. This lever can only be rotated for freeing the umbrella on the introduction of a specially-formed key.

In the accompanying drawings, Figure 1 shows a plan view of the umbrella-stand pro-- vided with the lockpFig. l a front view thereof. Fig. 2 shows in plan the interior arrangement of the lock. Fig. 3 is a section on the line a b, Fig. 2. Figs. 4, 5, and 6 show the tumblers of the lock in side and plan view. Figs. 7 and 8 show the lock-detent in side and plan view. Fig. 9 is a section onthe line C D of Fig. 7. Figs. 10'and 11 show the locking-lever in plan and side View, and Fig. 12 shows the key employed.

As can be seen from the drawings, the lockcase b is secured to the cast body-piece a by screws 00 x. In this case b are arranged the locking-lever c and the sliding detent d.

enter into the recesses u u of the detent d and in this manner prevent the longitudinal sliding of the detent, as now the angle-1e ver 0 is in engagement by means of its toothed sector 2 with the toothed portion a of the detent d. In this position, as can be seen from Fig. 2, the angle-lever c is locked. As soon, however, as the key 2', Fig. 12, is introduced through the guide f into the recesses la la k of the tumblers ll Z the latter,in consequence of the special formation of the recesses is k and of the key 1), will .be forced aside in both directions. When the keyz' has been inserted as far as possible, the tumblers [1'1 will so be pushed aside under the action of the springs 0 0 0 that the rolled projections s s of the recesses lo k of the tumblers enter into corresponding recesses in the key 1'. The openings m m m of the tumblers are hereby so actuated that the detent d or its projection It can be freed, whereby the locking-lever 0 can be rotated through a right angle for opening the lock. While the detent d is being slid the projection 72 remains in engagement with the recesses m m m of the tumblers, so that an unauthorized removal of the key '11 from the openings or recesses 70 It 70 is prevented, since the tumblers are also locked against sliding and the rolled projections 8 remain in engagement with the corresponding recesses of the key 1;. As soon as on inserting an umbrella or walking-stick the arm of the angle-lever is again rotated through a right angle, owing to the engagement of the teeth a z, the detent at will be brought out of connection with the tumblers Z Z Z which on withdrawing the key are moved to either side under the influence of the springs o 0 o in such a way that the recesses m m m of the tumblers lock the projection h of the detent cl in its position. The angle-lever 0 will hereby be brought into the locking position, so that the umbrella inserted will be completely secured against unauthorized removal. In order to secure the lock in its open or in its closed position, the spring at is provided, which so acts upon a nose t of the locking-lever c that the latter is certain to snap into one position or the other.

What I claim, and desire to secure by Letters Patent of the United States, is-

1. In an umbrella-stand, the combination 7 with a suitable casing, of an angular lockinglever formed with a toothed sector, a sliding recessed detent having teeth to engage those of the sector, and a series of tumblers adapted to be locked and released from engagement with the recesses in the detent,.substantially as shown and described.

2. The combination in an. umbrella stand; with a casing, of an angular locking-lever formed with a toothed sector, a sliding re able casing, an angular toothed lever, an ac- I 5 tuating-spring, a sliding toothed and recessed detent having a projection thereon, a series of recessed tumblers adapted to be locked or released by a suitable key, all constructed and adapted to operate substantially as shown 20 and described.

In testimony whereof I have hereunto set my hand in the presence of two Witnesses.

WILHELM HOLL.
