Application filed November 16,1919, Serial No. 131,632. Renewed January 80, 1920. Serial No. 355,194.

To all whom itmai 00mm.- I I Be it known that 1, JOHN BYRNE, a c1t1-1 Zen of the United States, andresident of San Quentin, California, have invented certain new and useful Improvements in Safety-Locks for Bottles or the like, of which the following is a specification.

This invention relates to improvements in a safetylock for'bottles or-the like, and has for its object an attachmentwhich can be readily and easily applied over the head and neck of a bottle or container with a locking means coming in contact with the under surface of the head of the bottle other medicine.

The device is simple, consisting of an outer shell with a means located therein which'can be operated by a key when it is desired to remove it from the head and neck of the container.

Figure 1, is a vertical central sectional view of, my complete invention showing it in its locked position on the bottle.

Fig. 2, is a central sectional View of the same taken on the line 22 of Fig. 1.

Fig. 3, is a top plan view with the cap removed.

Fig. 4, is a detail perspective view of the unlocking member made use of.

Fig. 5, is a detail perspective view of the rotatable member by which the unlocking member is raised and lowered.

Referring to the drawings in detail, 6 indicates a cylinder, its top being provided with a cap 7, which cap is centrally provided with an elongated slot 8, through which a key 9 may be inserted.

In the cylinder and at the top is located a rotatable sleeve 10, its surface is provided with two curvilinear slots 11, which act as a cam, the upper portion of the sleeve is provided with a rigid cross pin 19 against which the notch end 13 of the key contacts.

The bottom surface of the sleeve 10 is designed to; rest upon a pair of cross pins 14., which are firmly secured to the walls of the cylinder .6, the same being suitablyspaced apart as shown in Fig. 2, so as to act as a guide for the vertical arms 15 of the unlocking member 16, they bottom of the arms terminating in a ring 17. ring-is situated near. the bottom ofthe cylinder G, as shown and the same is raised and lowered by means of the pin 18 connected to the upper ends of the arms 15 and supported in and riding in the curvilinear slots of the sleeve 10.

On the inner surface of the cylinder (5 and near the bottom is attached a plurality of inwardly bent springs 19, the bottom ends of said springs being securely riveted in position while the inner ends are free, and the normal tendency of thesame is to bend inwardly and come in contact with the under shoulder 20 of the bottle head as is clearly illustrated in Fig. 1.

By means of the resiliency of these springs the device may be placed in position by forcing it downwardly over the head and as soon as the springs pass over the head and in a line with the shoulder they will automatically move inwardly, in this manner it will be utterly impossible to again remove the device from the bottle except when inserting the key 9 and turn ing it onequarter around which will cause the pin 18 to ride along the cam grooves and raise the unlocking member upwardly pressing the. plurality of springs 19 outwardly against the inner surface of the cylinder 6.

This

The free contacting ends of these springs being then removed away from under the contact with poisonous substance or dan gcrous ingredients without first acting as a warning that such substance and ingredients is contained in the bottle.

l -iaving fully described my invention what I claim is:

1. A device of the class described com-;

prising an outer shell, a rigid cap mounted thereon, a vertical operating unlocking member located therein, a plurality of springs attached to the inner surface of the shell and operated by the movement of the unlocking member and a partially rotatable sleeve in communication with the unlocking member, the partial rotation of the sleeve clevating'the unlocking member and straightening out the springs substantially as specified.

2. A device of the class described comprising a cylindrical member, a cap securely attached thereto, a partially rotatable sleeve supported in the top of the cylindrical member and provided with cam slots, an unlocking member attached thereto but permitted to operate 'ertically by the partial rotation of the rotatable member, the motion being imparted to the rotating member by means of a key inserted through the top, substantially as specified.

3. A device of the class described com- JOHN BYRNE.
