MANUFACTURE OF SILVERED-GLASS MIRRORS.
Specification of Letters Patent.
Original application filed June 22, 1909, Serial-No. 508,708.
Serial No. 568,155.
To all whom it may concern:
Be it known that I, EMILE Hoolnoxx, subof Bel' 'ium, residing at 308 Rue des Palais, Brussels, Belgium, have invented new and useful Improvements'in and Relating to theManufacture of Silvered- Glass Mirrors, of which the following is "a specification. 1 The present invention relates to a process of depositing on silvered mirrors a protecting layer, of copper or some other suitable metal by electrolysis.
It has for its object to provide a perfect connection between generator and the mirror.
This application is a division of my copending application, filed June 22, 1909, Serial N o, 503,708.
In the accompanying drawings: Figure l is an elevation of a connecting clamp; Fig. 2 is a view of the flexible conductor with the the negative pole of the layer of silver on the connecting pieces mounted on it.
' The current is conveyed to the silvered surface very carefully in order not to damage the surface. The device illustrated in Figs. 1 and 2 is well adapted for this purpose. The system consists in a series of spring clamps connected with each other and with: the negative pole of the current generator by means of a flexible conductor. These clamps clip the edges of the mirror and for this purpose consist each' of two parts, connected vpivotally together or simply connected together by an elastic connection, one of which is a contact finger, the part of with the layer of silver is connected electrically with the flexible conductor. Owing to this construction the current is conveyed to the silvered surface freely and smoothly whatever may be the position of the mirror or its thickness. of each clamp being'displaced during working of the apparatus, this being necessary in order that the portion of the layer of silver which is beneath the contact finger of the clamp may in its turn receive a deposit. The displacement of one clamp does not prevent current being conveyed to the layer of silver by the other clamps. Whatever may be the form of the mirror, that'is to say whether it is rectangular, oval, round or of irregular contour;v the clamps can always be applied Patented May 30, 1911. Divided and this application filed June :31,
along the edge of the mirror, the flexible conductor facilitating this. lVher'i the current is to be conducted by a single set-of clamps to several carriers of small dimensions this may be done without any difliculty.
In the clamp shown in Fig. 1, the member 20 is provided with a shoulder'21"and an extension '22, adapted to be applied to the under surface of the mirror 23, 13 connected with the member 2 1- by a caoutchouc band 30, preferably situated in a groove of suite ble cross section in the two members. The finger 25 is put into electrical connection with the conductor 27 by a metallic de osit 29. The members 20' and 24 are pre erably each provided with a groove 31 in which the conductor 27 may be situated so that it may form a fulcrum upon which the part 2 L turns. clamp is made of insulating material such impermeable wood, fiber or cbonite; in fact when the electroplating process is that generally used, the clamp must be covered completely with an insu ating varnish except at the end of the finger 25 contact with the mirror.
In order thoroughly to distribute the, current through the layer of silver a number of clamps are distributed along the sides of the which makes Preferably, the whole of the mirror, a single insulated conductor of suitable section connecting all the clamps or several of them with each other.
. A suitable flexible conductor is shown in section in Fig. 2; it comprises a number of short bars 27 which are the current terminals resting in the clamp member 20'; these are connected by soldering or otherwise with thin flexible conductors 32 contained within caoutchouc tubes 33 of suitable length slipped at one end on one of the bars 27' and at the other end ,on the next following bar so as to leave uncovered suflicient of the bar to form the the conducting surface of the clamp. The length of the flexible portion 32 is 0 course determined by the distance between the current terminals. The advantages which accrue from the flexibility of the conductor will. be obvious, for example, it enables the clamps to be satisfactorily connected with the mirror whatever the form or contour of the mirror may be.
Having now particularly described and ascertained the nature of my said invention necessary connection withw and in what manner the same is to be performed, I declare that What I claim is 1. In apparatus for electroplating mirrors, a single conductor and a plurality of means spaced from one another and connect- "ed electrically to said conductor and carried rors, a single conductor and a plurality of spring clamps carried thereby, said clamps being spaced from one another, each of said clamps comprising means for electrically connecting said conductor with the edges of the mirror to be electroplated.
3. In apparatus for electroplating mirrors, a single flexible conductor provided with a plurality of spaced rigid sections, and 0 means carried by each of said sections for electrically connecting said conductor with the edges of the mirror to be electroplated. 1
4L. In apparatus for electroplating mirrors, a single conductor and a plurality of spaced 5 means carried by said conductor for electrically connecting said conductor with .the edges of the mirror to be electroplated, said means extending substantially atright angles with said conductor.
In testimony whereofI have signed my name to this specification inthe presence of -two,subscribing witnesses.
