THOMAS B. CLEVELAND, OF NElVARK, NEW JERSEY, ASSIGNOR TO ISAAC A. .ALLING, HORACE ALLING, AND R. ALLING, OF SAME PLACE.

SPRING-HINGE FOR BRACELETS.

SPECIFICATION forming part of Letters Patent No. 248,142, dated October 11, 1881.

Application filed June 17, 1881. (No model.)

To all whom it may concern:

Be it known that I, THOMAS E. CLEVELAND, a citizen of the United States, residing in Newark, New Jersey, have invented an Improved 5 Spring-Hinge,ofwhich the t'ollowingis a specification. 5 1

My invention relates to an improvement in that class of spring-hinges for bracelets and otherarticles ofjewelryin which aspiral spring I0 is contained within the eyes of the hinge; and

my improvement consists in a peculiar manner, fully described hereinafter, of constructing a hinge of this class with the view of readily introducing the spring into its place.

In the accompanying drawings, Figure l is a perspective view of a bracelet with my improved spring-hinge, and Fig. 2 an enlarged sectional view of the hinge.

The two segmental halvesAAof the bracelet are furnished at their front ends with any suitable spring-catch device the other ends of the segments being connectedgtogether by a spring-hinge, thepeculiar manner of constructing which constitutes my invention;

On the segment A of the bracelet are two eyes, a a, and ,on the segment A are two similar eyes, I) b, the eyes of the two segments being arranged to tit together, as shown in Fig. 2. i

- 0 To the opening presented by the combined eyes of the two segments is adapted a coiled 1 spring, (I, which isastflong as the bracelet is wide from edge to edge lthe wire at one end,

00, of the spring terminafin-gt tbruptly, and at the other end, y, projeeting from the convolution of the spring.

That end, as, of the spring where the wire terminates abruptly presents no obstruction to the introduction of the saidspringinto the 40 opening presented. by the combined eyes of the two segments of the bracelet, and in thus introducing the spring theprojecting end yet the wire is fitted into the recess mot the eye a of the segment A, while the abrupt end or of the wire abuts against an internal lug, i, in

.the eye I) of the segment A. After the spring has been thus introduced into its place, a. pin, f, is passedthrough it and through a washer,

e, the projecting en dbein g then riveted againstthe washer. 0

The tendency of the spring is to maintain the bracelet in a closed condition, tension being imparted to the spring when the bracelet is opened, and the spring recoilingwhen the segments of the bracelet are released.

The spring being of small diameter and concealed from view, the hinge presents an appearance differing but slightly from an ordinary hinge without a spring.

Thetwo segments of the bracelet have the usual guards for limiting the extent to which the bracelet can be opened.

There may be more than two eyes on each segment of the bracelet, and the invention may be applied to articles of jewelry other than bracelets in fact to any small articles which require neat' spring-hinges.

I am aware that a spiral spring has been ---c'om l1 ine d with the hinge of the two segments of 'a bracelet, and that a spiral spring has been contained within and concealed by the eyes of a hinge, but this spring was not constructed for introduction into and application to the eyes in the manner described above.

'I claim as my invention The combination of the eyes a a and I) b ofa spring-hinge, the eye I) having an internal lug, i, and the eye (ta recess, m, with a rivet or pin,f, and with a spiral spring, the wire of which terminates abruptly at one end or, for abutting against the said lug i, and the other end projecting at 3 for fitting into the said recess on, all as set forth.

In testimony whereofI have signed my name to this specification in the presence of two 8 subscribing witnesses.

THOS. B. CLEVELAND;
