E. HARRISON GRIFFIN, OF NEW YORK, N. Y.

UMBRELLA-LOCK.

SPECIFICATION forming part of Letters Patent No. 313,493, dated March l0, 1885.

Application filed January 9, 1884. (No model.)

To all whom t may concern.-

Beit known that I, E. HARRIsoN GRIFFIN, a citizen of the United States, residing in the city of New York, in the county and State of New York, have invented certain new and useful Improvements in Locking Devices for Umbrellas, of which the following is a specification.

My invention relates to a lock to be applied to an umbrella, so that when not in use it may be locked or fastened so as not to be opened by one unfamiliar lwith the mode of operation; and it consists of the devices shown in the drawings and hereinafter described.

In the drawings, Figures l and 2 show different methods of applying my device so as to fasten an umbrella, the lock being in position to hold the umbrella closed. Fig. 3 is a sectional view of one of the movable double rings B. Fig. 4 is a cross-sectional view of the same. Fig. 5 is an exterior side view of one of the movable rings shown in section in Figs. 3 and 4, with combination-letters thereon. Fig. 6 is a plan view of the sliding tube with the fixed rings and one ofthe movable double rings thereon. Fig. 7 is the same in section with the movable double ring omitted, and Fig. 8

a section of the sliding tube and fixed ring.

The same letters of reference refer to similar parts in all the drawings.

A is the stick of the umbrella, and C a tube sliding freely thereon. The tube C may be either the runner to which the rib-braces c c are fastened, or it may be a tube working separately and placed on the .'stick A below the rib-cap H, as shown in Fig. 2.

On each end of the tube C are placed the fixed rings C U', which may loe formed by turning back the ends of the tube C, or by soldering to the tube C a ring having one edge turned down in a ange.

On the outside of the tube C, and between the xed rings C C, are placed the double movable rings B B, of which I use, preferably, two, though there may be three or more, and of such width as to completely fill the space between the fixed rings C C'. The double rings B B consist of an outer ring, D, and an inner ring, E, soldered to the outer ring, as at h, and having a slot, F, as shown in Fig. 4. The tube C has cut in it the slot G, extending lengthwise, and so placed and of such length that the spring S shall set up through the slot G and hold the tube C in position when the slot is moved overthe spring, and the slotsF in the inner ring, E, are coincident with the slot G.

On the movable rings B B and the fixed rings G are marked letters or figures, as shown in Fig. 6, of which there may be any number, and so placed that when certain letters on the movable rings are in line with the proper ones on the fixed rings the slots in the inner rings, E, will be directly over the slot G.

The mode of operation is as follows: When the umbrella is closed, the slot F being over the slot G, the spring S stands up in the slot G and the tube C is held in place. The double rings B B are then moved so that the inner ring, E, passes under the spring S, thus holding it between the inner and outer rings and preventing it from being pressed down into the recess provided for it, thus making the moving of the tube C along the staff, and consequently the opening of the umbrella, impossible until by turning the rings so as to form the proper combination of the letters thereon the slots F are again brought over the slot G. The spring S will then give way into the recess in the staff, when the `tube C is pushed against it and permit the opening of the umbrella.

Vith such a device the locking mechanism is entirely concealed from view, and it is impossible to open the umbrella until all the slots F are brought over the slot G.

Any desired. degree of intricacy in the combination may be obtained by increasing the number of the movable rings B B.

Instead of applying the locking device to the tube to which the rib-braces are attached, it may be employed as shown in Fig. 2. Here a separate tube C is placed on the umbrellastaff below the sliding cup H, which fits over the ends of the ribs. When the umbrella is closed, the cup H is slipped up so as to confine the ends of the ribs, and the tube C is then pushed against'it, and then locked by means of the spring S and movable rings B B, as before. TWhen I apply the device in this way, I bend the rib-tips a: .fr at right angles, or

ymake them somewhat larger than usual, so

that they may be firmly held within the lip or fiange ofthe cup H.

I am aware that combination-locks having Ioov letters and figures thereon have been heretofore applied to umbrellas, and I do not broadly claim such device as a part of my invention.

What I do olaim as new, and desire to secure by Letters Patent, is-

1. The eombination,with the staff' of an um- 2. The combination, with the retainingspring of au umbrella or parasol and the runner-tube thereof, of one or more double rings, B, formed of a complete outer ringr and aslotted inner ring, the inner ring being adapted to engage under the spring and prevent its brella, of a movable tube, O, provided with l being pressed down, substantially asset forth. fixed rings C and movable double rings B, each formed of a complete outer ring and a slotted inner ring firmly fastened thereto having letters or gures on their outer surface, substantially as and for the purposes set forth.
