PIN SAFETY-LOCK.

Specification of Letters Patent.

Application filed March 8, 1911.

Patented Jan. 23,1912.

Serial No. 613,026.

To all whom it may concern:

Be it known that I, SOIHUS J. E. VVIL- HJELM, a citizen of Denmark, and a resident of Brooklyn, Kings county, New York, have invented certain new and useful Improvements in Pin Safety-Locks, of which the following is a specification.

This invention relates to improvements in safety looks or guards for jewelry and like articles. The invention, however, is not limited to such use but may be found practical, useful and applicable in connection with other articles and for other purposes.

The detailed construction of my invention is fully set forth in the following specification while reference is had to the accompanying drawing in which- Figures 1 and 2 are side views of a brooch pin embodying my invention and showing the pin in closed and open positions respectively. Fig. 3 is a sectional view on line 83 of Fig. 1. Fig. 4 is a view of the blank which forms one element of the invention. Figs. 5 and 6 are views of a modified form of the invention showing two steps in the process of making it.

Referring to Figs. 1 to 3 the numeral 8 represents a brooch or like article and 9 is the pin for securing the brooch in the usual manner to the garment. The two principal objects of the invention are to provide a safety locking device for locking the pin firmly against accidental or untimely opening and to form the locking means in such a manner that the point of the pin is contained within the lock to prevent injury. In the present instance I accomplish these objects by the following means. Referring to Fig. 4, 10 is a blank stampedor made to form a base 11, two perforated pivot lugs 12, 12 and a pin guide 13. It may be made of any suitable metal and the base 11 is secured to the back of the brooch by solder or otherwise. 14 is a spring locking member freely rotatable on the pivot pin 15 which is inserted in the pivot lugs 12 as will be understood. The spring '14 is provided with an aperture 16, see Fig. 3, to permit the spring to pass over the pin point 17 of the brooch 9. The spring 14 is an expansion spring and has the tendency to throw the free end 18 outwardly or to the right in the drawing.

The operation of the device is simple. When the brooch pin is looked as in Fig. 1 it passes through the aperture 16 in the spring 14 and the point 17 is contained within said spring thereby preventing injury. Further, the brooch pin cannot be opened without moving the spring endwise of the brooch or to the right and this cannot be to be locked it is laid down in the forked portion in the guide piece, which registers with the opening 16 and the spring lock is then snapped up over the pin point 17 as in Fig. 1, whereby the free end 18 is forced outward and thus automatically locks the pin which cannot be unlocked except by manual operation.

The guide piece is not essential to the successful operation of the device but helps to prevent sidewise movement of the pin 9, and to position the latter with respect to the opening 16 in the spring 14.

In Figs. 5 and 6 is disclosed a device for securing the end of a watch chain or other article. In this instance there is formed a blank 20 having a ring 21 to which a watch chain may be attached. 22 is the pin portion and 23, 23 the pivot lugs. The portion 24 forms a base similar to the base 11 above. After the lugs 23 are bent at right angles to the base portion 24 the pivot pin 15 and the spring 14 is inserted as before, after which the blank is given a quarter turn as at 25 to bring the lock in proper position under the pin 22. The operation for locking and unlocking the latter is the same as above described. This device may be used at the edge of a vest where either the pin is looked through a button hole or the pin may be shaped to easily penetrate the garment. The distance between the 'lock and the ring 21 depends somewhat upon how the device is to be used. The pin 22 may be very short and springy if desired.

From the foregoing it will be seen that I have invented a pin safety lock of very simple and practical construct-ion, and which may be used for purposes entirely'different from those disclosed without materially changing the construction or departing from the spirit of the invention.

I have found that this device may be made at little cost and works well.

The device may be either made to be attached to a piece of jewelry already made or itmay be incorporated in the article while the latter is being constructed.

I claim:

1.- The combination of a brooch, a pin for securing the same, a spring adapted to lock the said pin, said spring being bent in the form of an upwardly curved loop and provided with an aperture to admit the point of the said pin to project within the said formed loop and having a free end portion abutting the said brooch at right angles thereto for preventing accidental removal of the said pin, the said spring being adapted to be moved away from the point of the pin to release the latter.

2. The combination of a brooch, a pin for securing the same, a locking spring adapted to engage the said pin to lock the same and having a free end portion adapt- .ed to engage the said brooch to prevent accidental removal of the pin, said free end portion when locked standing at right angles to the brooch and in front of the said pin to protect it against injury and adapted to be bent in under the point of the pin to release the latter.

3. The combination with a brooch and a pin for securing the same, of a locking means for said pin comprising a spring pivoted at its one end to the said brooch, the body of the spring being bent to form an upwardly curved loop and provided with an aperture for the passage of the pin to secure the latter, the other free end of the spring being adapted to abut the brooch at right angles to prevent accidental removal of the Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, Washington, D. G.
