0@ S *5 S S *0U The following statement is a full description of this invention including the be~st method of performing it known to us:- 1A FIELD OF THE INVENTION The present invention relates to articles of jewellery and to processes for manufacturing same.
The technical sector of the invention is that of the manufacture of certain articles of jewellery, such as, for example, pens, lighters, bracelets, necklaces, ear-rings, pendants, etc...
BACKGROUND OF THE INVENTION Tubular metallic braids are known which are composed of interwoven metal filaments or strips and machines are also known for industrially manufacturing such tubular braids. Such braids are used in particular for sheathing flexible tubes in order to increase their resistance to pressure and to protect them mechanically.
o.S Metallic braided sheathes are also used for enveloping electric cables in order to protect them '"mechanically and also to form an electrical screen which is at the potential of earth or ground.
The present invention proposes a novel application of 20 tubular metallic braids.
It would be desirable to provide articles of jewellery, i.e. articles composed of precious metals such as gold, silver, platinum or stainless metals which present an ornamental and original outward appearance and 25 which may be manufactured industrially, using a relatively low weight of precious metal.
see* SUMMARY OF THE INVENTION The present invention provides an article of jewellery, a pen or a lighter which comprise a tubular braid composed of interwoven strips or filaments of precious or stainless metals, which braid constitutes at least a part of the visible surface of said article of jewellery.
The articles of jewellery according to the invention advantageously comprise a braid composed of interwoven 2 strips, in which each strip is constituted by a plurality of identical, juxtaposed filaments of precious or stainless metal.
According to a preferred embodiment, the articles of jewellery according to the invention comprise a tubular braid which is composed of interwoven filaments or strips of various colours.
According to a preferred embodiment, the articles of jewellery, the pen or the lighter comprises a rigid cylindrical body and a tubular sheath which envelops said rigid body and which is constituted by the tubular braid, which tubular braid is fixed to said rigid body by its two ends whilst being maintained under tension, with the results that the tubular braid is applied against said C. *eR 15 rigid body and said interwoven strips form therebetween free spaces through which said rigid body is visible.
The present invention also provides a process for S* SR manufacturing an article of jewellery comprising a rigid cylindrical body, comprises the following successive operations: making a tubular braid formed by strips or filaments of precious or stainless metals on a cylindrical e. mandrel having a diameter slightly greater than the diameter of said cylindrical body; removing said braid from said mandrel; R* fitting said braid over said cylindrical body; :*fe longitudinally stretching said braid, thus reducing the diameter of the latter which is applied against said cylindrical body; fixing the two ends of said braid to said cylindrical body; and engaging around each of the ends of said braid a metal ring which is welded on said body and/or on said braid.
The invention results in novel articles of jewellery, particularly pens, lighters or other articles comprising a rigid cylindrical body, of circular or ovalized section, which body is enveloped in a sheath constituted by a tubular braid formed by interwoven strips or filaments of precious or stainless metals and preferably in various alternating colours, which gives these articles an original, ornamental outward appearance.
These articles of jewelry present the advantage of b-eing able to be manufactured industrially for a relatively moderate cost.
In fact, machines are known, capable of industrially OS SO S manufacturing a metal braid on a cable or on a tube S" and it is therefore easy industrially to manufacture tubular braids composedof filaments orstrips of precious r 15 or stainless metals.
Moreover, the metal braids present the property of being easily deformable.
In particular, they may be drawn, which makes it possible to reduce their diameter or their transverse 20 dimension.
005S00 S" They may also be manufactured on cylindrical man-
OS..
drels having a transverse section other than circular, go for example an oval transverse section.
0 In order to manufacture articles of jewelry such as for example pens or lighters which comprise a rigid cylindrical body having a circular or oval transverse section which it is desired to envelop in a tubular 6 braid, a tubular braid may therefore firstly be manufactured industrially on a mandrel whose transverse section is similar to that of the cylindrical body and of slightly greater dimensions, so that it is easy to engage the cylindrical body inside the braid without requiring any precise machining, the tubular braid is then stretched longitudinally so that its transverse section is reduced and it is applied against the rigid tubular 1
L
-4body, and the braid is then fixed to the body for example by welding the two ends of the tubular braid to the rigid body.
This process for assembling a tubular braid on a rigid body presents, moreover, the advantage that extension of the tubular braid causes diamond-shaped openings to appear between the strips or filaments which move apart from one another and the rigid body is visible through these openings, this contributing to giving the article of jewelry an original outward appearance.
In the case of a pen or lighter which is held CO CS S• between the fingers, the latter are in contact with the tubular braid which envelops the body of the article, so that the skin penetrates slightly in the openings e 15 of the braid, hence a very good adherence which avoids the risks of sliding in the fingers.
The articles of jewelry according to the invention may also be jewels such as bracelets, necklaces, pendants or ear-rings of which a part is constituted by a tubular 20 braid composed of interwoven filaments or strips of preci6us o o metal.
The presence of a tubular braid reduces wear of the rigid body that it envelops and enables the surface beauty to be maintained for a longer time.
BRIEF DESCRIPTION OF THE DRAWINGS The invention will be more readily understood e* on reading the following description with reference to the accompanying drawings, in which: Figure 1 shows an axial half-section and a half-view of the outside of a pen body according to the invention.
Figure 2 is a transverse section along II-II of Figure i.
Figure 3 shows an axial half-section and a half-view of the outside of a lighter according to the invention.
Figure 4 is a transverse section along IV-IV of Figure 3.
Figure 5 shows an axial section of an article in the course of manufacture.
DETAILED DESCRIPTION OF THE DRAWINGS Referring now to the drawings, Figures 1 and 2 show a pen which comprises a rigid cylindrical body 1 having a circular section. It is question of a pen sold in a jeweller's and the body 1 is made of precious metal or gold-plated metal.
The body 1 contains the ink reservoir and an internal mechanism which are not shown.
S* The cylindrical body 1 is enveloped ever the whole of its length by a sheath 2 which is a tubular braid comss _Dposed of. filanents or strips of precious or stainless oe:. 15 metal, which are disposed in several directions and which are interlaced or interwoven.
06 Figure 1 shows a preferred embodiment, comprising strips 3 parallel to one direction and strips 4 parallel to another direction, each strip being constituted by a plurality of identical, juxtaposed small filaments, having a very small diameter, for example a diameter S6 of 0.2 mm, so that the weight of precious or stainless metal per unit of length of the braid is relatively e* a low, of the order of 5 to 10 g for the whole of the braid adorning the pen.
The strips having the same direction are alternately in two different colours. For example, strips 3 comprise golden-coloured strips 3a which alternate with silvercoloured strips 3b.
Similarly, strips 4 alternately comprise strips 4a of one colour and strips 4b of another colour and these colours may be respectively identical to the colours of strips 3a and 3b or different from these colours.
These alternating colours give the braid which constitutes the major part of the visible surface of the pen, ar original and ornamental outward appearance.
The two ends of the tubular braid 2 are fixed on the ends of the rigid body 1, for example by welding.
These ends are advantageously hidden by a ring which surrounds each end of the body 1 and which is welded on the body and/or on the braid.
Figures 3 and 4 show a lighter which comprises a rigid cylindrical body 6 having an oval transverse section which contains the fuel reservoir and the mechanism of the lighter (not shown).
This lighter further comprises a cap 7 likewise presenting a cylindrical rigid body which fits on body to•* 6.
o 15 Body 6 and cap 7 are each enveloped in a sheath S 8, 9 which is a tubular braid composed of interwoven os strips or filaments of precious or stainless metal.
The composition of braids 8, 9 is identical to that of braid 2. They differ from the latter solely 20 by the oval shape of the transverse section which is oieoo obtained by making braids 8 and 9 on an oval mandrel.
•coo The two ends of each braid 8, 9 are fixed to the rigid body which is enveloped by the braid and are czvered by a ring 10. The upper ring 10 of the lighter body 6 is slightly recessed with respect to the upper end of the body to allow the cap 7 to fit on the body 6.
A process for manufacturing a pen according to Figures l and 2 comprises the following operations.
A tubular sheath is firstly manufactured, composed of filaments of precious or stainless metal having a diameter of the order of 0.1 to 0.2 wm, which are braided. This operation is effected on a machine of the type such as used for making braided sheaths for enveloping electrical cables or flexible tubes.
The tubular sheath is composed for example of 1 9 -7interwoven strips, each strip being composed of a plurality of identical, juxtaposed filaments. The strips are disposed for example in two directions. For example, the braid comprises strips 3 which are wound in parallel helices rotating in one diretion and strips 4 which are wound in parallel helices, of the same pitch and in a direction opposite the direction of helices 3.
In this way, each strip 3 successively intersects strips 4, passing alternately above and below the successive strips 4, thus being interwoven and interlaced.
The tubular braid is made by winding the strips around a cylindrical mandrel whose diameter is slightly greater than the diameter of the rigid body 1 of the o. pens.
0*S* e* 15 The successive strips of the same direction may be juxtaposed or slightly moved apart from one another and, in that case, the braid comprises diamond-shaped openings which are defined by four interwoven strips.
Once the braid is made, it is removed from the mandrel of the machine on which it was made, and it is cut into sections 2 having a length equal to or S less than the ler.gth of the rigid bodies 1.
Figure 5 shows the following step.
Pen bodies 1 generally comprise a female thread 2a, 2b at each of their ends.
There is screwed on each end of the body 1 a small O threaded endpiece 11 comprising a male thread which .is screwed in the female thread of the body. These endpieces are composed of a material which withstands the temperature of the welding oven. For example, threaded endpieces made of graphite or ceramics are used.
These endpieces have for example a length of the order of a centimeter and they project on each side of the body i.
A pen body 1 fitted at its two ends with an endpiece -8- 11i is then introduced into each section of braid 2, previously cut out to the length of the pen body.
This operation presents no difficulty since the t.ubular braid has an inner diameter which corresponds to that of the mandrel on which it was made and which is greater than that of the pen body.
The tubular braid 2 is then stretched longitudinally, so that it is drawn, covering the endpieces 11,ii and its internal diameter decreases.
It is stretched until it is firmly applied against the outer surface of the rigid body i. The two ends :0 of the tubular braid 2 under tension are then fixed to the two endpieces 11 by any fastening means, for example by clip-shaped collars 12.
15 Once the taut braid is fixed around the body, o welding paste, which corresponds to the nature of the metals constituting the braid and the body i, for example gold paste in the case of body 1 being made of gold or gold-plate and braid 2 being made of gold filaments, is applied on the braid, around the two ends of the body 1.
Body 1 bearing the braids coated with welding paste is then introduced into a welding oven, which *results in the braid being welded to the ends of the body 1.
The action of the heat on the braid also has for •its effect to anneal the braid and therefore to reduce the internal tensions in the braid which tended to return it to its initial state.
The body 1 bearing the braid welded thereto is removed from the oven, the clips 12 as well as the endpieces 11 are removed and the excess lengths of the braid are cut, i.e. those parts projecting beyond the ends of body i. A ring 5 which was internally coated with welding paste is then fitted on each end of the -9braid and the' body is again introduced into an oven to weld the rings on the ends of the braid. The duration of the second dwell time in the oven is shorter than the duration of the first, in order to avoid melting the weld of the braid on body 1.
A lighter according to Figures 3 and 4 is manufactured with the same sequence of operations, but this sequence is repeated for body 6 and for cap 7. The only difference resides in the fact that the tubular braid is made on a mandrel having an oval section corresponding to the section of the lighter.
*Figures 1 to 4 show articles of jewelry comprising a rigid cylindrical body having a solid wall. It is specified that, in the case of jewelry such as bracelets 15 or necklaces, the rigid body may be in the form of open-work or constituted by longitudinal strips which OS maintain the braid taut.
