SAFETY-CATCH.

Specification of Letters Patent.

Application filed November 14, 1913.

Patented J ul y '7, 1914.

Serial No. 800,994.

To all whom it may concern:

Be it known that I, CHARLES D. HEATON, a citizen of the United States, residing at Providence, in the county of Providence and State of Ithode Island, have invented certain new and useful Improvements in Safety-Catches, of which the following is a specification.

My invention relates to safety catches for locking pin tongues upon brooches and other articles of jewelry.

The essential objects of my invention are those commonly sought in structures of this character, and more particularly to provide an engaging means wherein the constituent parts of the catch will not readily become bent and disassembled; to reduce the labor and expense of manufacture to a minimum; and to increase the security and facility of action of the parts.

To the above ends essentially my invention consists in such parts and combinations of parts as fall within the scope of the appended claim.

In the accompanying drawings which form a part of this specification Figures 1, 2, and 3, are plan, side, and end elevations respectively of my novel catch afiixed to a pin or brooch, Fig. 4, a section partially in elevation taken on line m m of Fig. 1, Fig. 5, a section on the same lineshowing the parts in open position, Fig. 6, a perspective view of the movable member, Fig. 7 a section of the fixed member of the catch taken on line y, y, of the Fig. 1, and Fig.8, a like section of a modified form of my catch.

Like characters of reference indicate like parts through the views.

In the drawings 1 is a pin or brooch body, carrying a joint 2, upon whose pintle 3 is mounted a pin tongue 4. It is in conjunction with these familiar parts that my safety catch is in the present instance described.

The body portion of my catch is preferably machined from a cylindrical rod cut in uniform lengths, and in detail comprises two end plates or supports 6 connected by a cylindrical bar 7 of less diameter than the plates. The supports 6 may be soldered or otherwise fixed to the brooch. body 1 or other article in conjunction with which the catch is to be used.

The rod,bar, or cross piece portion 7 is provided with a longitudinally disposed U- shaped channel or groove 8, which groove is continued through the end plates as at 9, 9. The described member 6, 7 forms a cradle to receive the pin tongue 4 in the groove 8, which groove is sufliciently deep to embrace the pin tongue. To cooperate with the cradle is a resilient or spring clamp member 10, comprising a curved loop or body portion 11 terminating in two arms 12, having inwardly curved or retracted portions 13 near their ends, thus making the inner or bearing face of the member 10 somewhat greater than a semi-circle. The latter member tightly embraces the portion 7 of the cradle, but is rotatable thereon, when manually manipulated, by virtue of its resilient character. The width of the member 10 is such as to be a sliding fit between the shoulders 6 of the cradle member.

When the catch is in open position to receive the pin tongue, the arms 12 are in up right position as shown in Fig. 5. After the pin tongue 4 is pressed down into the groove 8, the member 10 is manually rotated a quarter turn, bringing the arms into horizontal position, with the member 10 clasping or pressing the tongue 4 in its seat.

While the described form of clamp is more effective in operation it will be understood that it need not be angular in cross-section. In Fig. 8 it is shown curved in cross-section,

14, in which case the face of the cross-piece CHARLES D. HEATON.
