MOLDED BRACELET Filed Ma r ch 16, 1944 I INV NIOR Mafia/0'6 Bar zelit ATTORNEYS Patented June 17, 1947 UNITED MOLDED BRACELET Nicholas Barbieri, Providence, R. I., assignor to Uncas Manufacturing Company, a corporation of Rhode Island Application March 16, 1944, Serial No. 526,778

1 Claim. 1

This invention relates to an extensible article and more particularly to a flexible extensible bracelet.

Heretofore in the formation of bracelets of plastic material any relative movement of the parts of the bracelet have depended upon some jointed connection While often the bracelet has been of a rigid band-like construction.

One of the objects of this invention is to provide a bracelet formed of plastic material which will have some extensibility in the direction of length.

Another object of this invention is to provide an inexpensive bracelet by reason of its being formed in one integral piece of material bendable and extensible.

Another object of this invention is to provide a bracelet which may be formed in various shapes that its parts may take on various ornamental forms.

Another object of this invention is to provide a bracelet which may be formed in substantial lengths and cut off to provide bracelets of the length desired.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claim.

In the accompanying drawings:

Fig. 1 is a top plan view of a bracelet formed in accordance with this invention;

Fig. 2 is a bottom view of the same bracelet;

Fig. 3 is an end view on substantially line 3-3 of Fig. 2;

Fig. 4 is a sectional view on line 4-4 of Fig. 1;

Fig. 5 is a view similar to Fig. 1 illustrating a length of the bracelet in expanded position;

Fig. 6 is an edge view of the expanded relationship shown in Fig, 5 and the same being disposed arcuately;

Fig. '7 illustrates a mold from which the bracelet above illustrated was molded;

Fig. 8 is a view similar to Fig. 1 modified in that the obverse portions are of a different shape; and

Fig. 9 is an end view of the structure shown in Fig. 8.

In proceeding with this invention I mold a bracelet in separable dies and in a manner illustrated and described more particularly in my copending application filed of even date herewith. A plurality of members are connected together so that in effect a distorted or flattened helix is provided which may be extended in the direction of its axial length by reason of the inherent resiliency of the material of which the same is molded.

The article which I have produced consists of a plurality of members It! arranged in parallel relation with their ends ll all the same distance from the central axis of their assembly so that a straight edge might be placed along the edge of the assembly and touch each of the member ends.

This set of members may be termed the front or top of the bracelet or article and a second set of members designated generally l2 are also in parallel relation, which may be termed the back or bottom set of members is also provided. The members II and I2 are integrally connected at their ends by reason of the offset portion l3 of the members It] overlapping the offset portion M of the members l2 and being molded from one integral plastic mass which is extruded through recesses l5 and I6 entering from a gate I! in a mold shown in Fig. '7. This manner of forming serves to connect the portion of the bracelet Ill and I2, which I term members, at their ends something after the shape or form of a flattened helix as may be illustrated more clearly in Figs.

. 5 and 6.

This molding takes place about a central core or flattened strip l9 which may be removed leaving a central channel opening 20 through the bracelet as shown in Fig. 4 or in Fig. 3. The end portions l3 and I4 being the only portions connected will admit of certain bendings or flexings and yet will when sobent or flexed be under an inherent tendency to return to their former position, thus giving elasticity lengthwise of the bracelet.

In some cases instead of having a shaping of the members, as shown at It and 12, the shaping may be as shown in Fig. 8 at 22 and 23 with the connections as at 24 and 25 that a leaf form extensible bracelet may be provided.

I claim:

An extensible bracelet comprising a set of 3. plurality of members arranged in parallel relation and a second set of members connecting the first set by each second set member being attached to one first set member at one edge of the set and attached to the next member at the other edge of the set there being sufficient flexibility at said connections to permit extendibility of the members as a whole, said members being of a material and of a size to provide relative rigidity in the individual members NICHOLAS BARBIERI.
