2 Claims; (01. se -so 'My invention relates to chains adapted primarily for use in the jewelry art for bracelets, girdles, necklaces, anklets, arm bands and the like.

The essential objects of my invention are adaptability to the display of any desired surface ornamentation by engraving, stones, or other ornaments; to insure lightness of weight combined with adequate strength; to enable the use of a soft metal in construction; to permit a measure of transverse or lateral flexibility together with longitudinal flexibility to insure such strength of connection of the units as to prevent breaking or loss of the latter; and to attain these ends in a structure inexpensive to manufacture, and wherein units maybe easily removed or substituted.

With the above and other objects and advana tageous features in view, the invention consists of the arrangement of parts and details of construction more fully disclosed in the detailed description following, in conjunction with the accompanying drawings more specifically defined in the claims appended thereto.

In the accompanying drawing forming a part of this specification,

Figures 1 and 2 area plan and side elevation respectively of a series of my novel units assembled into a chain embodying my invention,

'Figure 3, a longitudinal section of the same taken on line 33 of Figure 1, 1

Figure 4, a perspective view of a link prior to closing down the tongue, I

Figure 5, a side elevation of two links partially interengaged, and

Figure 6, a central longitudinal vertical section of the same.

Similar reference characters indicate similar parts throughout the views. 7

The chain 1 comprises a plurality ofnovel units 8 adapted for facile interengagement. Each unit is composed of a relatively soft metal including tin or the like as one ingredient such as Britannia metal, which imparts a greater degree of pliability and less hardness than brass. For this reason the bending operation involved in the construction of the link is facilitated and the metal is more adapted for the formation therein of seats for stones or other desired ornaments.

The units are individually formed in one piecerear ends outwardly inclined plane faces con- 1 stituting diverging end abutments l2. The points ID are laterally curved. Integral with the concave or inner sides of the segments, intermediate their lengths, and oppositely disposed with relaf the abutments ii, the diameter of the former being less than the area of the latter. Transversely disposed rearwardly inclined spacing bars 9 integral with each unit extend from the lower portions of the rear shoulders [2 to a longitudinally disposed tongue 2c of flat stock comprising a vertically disposed rear portion 2|, and a forwardly directed portion 22 laterally tapering at its free end to a point 23. The under surface of the portion 22 is provided with a longitudinally disposed convex: shoulder 26. The inner ends of the pivotbars H) are fixed to or integral with the opposite sides of the tongue portion 2i atthe lower end of the latter.

In the initial step of assembling a plurality of units into a chain the portions 22 of the tongues are originally in horizontal or elevated position, as shown in Figures and 6. To interengage the units the cross bar N3 of the rear unit is inserted under the tongue of the forward unit and is drawn rearwardly until said bar abuts against the portion 2| of the tongue, and the bars !9 of the forward unit loosely register in'the grooves l5 of the rear unit.

The next step is to manually depress the forward portion of the tongue 20 of the forward unit until the point portion 23 thereof reaches a position between the knobs or projections l3 where which permits a slight vertical movement of the bar 18 therein whereby the chain has a capacity for flexibility in a vertical direction.

The chain has some flexibility also transversely in a horizontal plane since the abutments ll of the body segments 9 are spaced somewhat from the sides of the tongue portion 2|, as at 29, and the curved outer faces of the point portions of the segments are slidable against the abutments l2, and the recess 21 affords sufiicient space to allow the bars l9 to ride out of the grooves I 5 when the engaging unit is transversely tilted.

I claim:-

1. An ornamental chain comprising a plurality of units of relatively soft metal, each unit consisting of horizontally convexo-concave body segments provided upon their forward ends with points and with abutments and at their rear ends with abutments, a cross bar connecting the for-, ward abutments, a longitudinally disposed tongue between the segments adapted to receive the cross bar of an adjacent unit comprising an upwardly directed rear portion and a downwardly inclined forward portion, spacing bars connecting the rear abutments to the lower end of the rear portion of the tongue to loosely receive the points of an adjacent unit therebetween, and projections upon the segments fixed to the forward portion of the tongue. 7

2 An ornamental chain comprising a plurality of units of relatively soft pliable metal, each unit consisting of vertically arched horizontally convexo-concave segments having top and bottom faces and provided upon their forward portions with lateral abutments and upon their lower faces adjacent the abutments with transversely inclined grooves, and provided at their rear ends with abutments, a cross bar connecting the forward abutments, a tongue adapted to receive the cross bar of an adjacent unit comprising an upwardlydirected rear portion and a downwardly inclined forward portion, rearwardly inclined spacing bars connecting the rear abutments to the lower end of the rear portion of the tongue to loosely receive the forward extremities of the segments of an adjacent unit therebetween, the spacing bars being adapted to loosely register in the grooves of the adjacent segment.
