MANUFACTURE OF SILVER-ED-GLASS LMIRBORS Application filed Jane 22. 1909. Serial No. 508.708.
To oft whom it may concern:
lie it known that 1 EMILE llooincnx,
' subject of Belgium, residing at 30%; line des Palais, ln't ls, Belgium, have invented new and useful Improvements Relating to the Marnifaeturtof Silvereddilass Mirrors; and I. do hereby declare the following to be a full, clear, and exact description of the same.
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 mechanism for imnnj-rsing the mirrors in the electrolytie bath. This mechanism is so constructed that by a single manipulation the frame carrying the mirr and that :arrying the anode are immersed in the, electrolytic bath in such a manner that the mirrors travel oblitpiely into the bath and are completely immersed therein before the frame carrying the anode has entered the bath. The oblique passage of the mirrors into the bath avoids the d tnrbanee of the liquid which occurs when the mirrors enter the liquid normally to thesurface thereof. On the other hand, the fact that the mirrors are completely immersed before the frame carrying the anode has begun to enter the bath, has the important result that there can be no localization of the current on a small portion of the silvering of the niirro and a burning thereof as occurs if the niirrms are only partially immersed in the bath when the anode comes in contact with the latter.
In the accompanying drawings: Figure la is a vertical section through a vat provided with a device for immersing the mirrors horizontally: Fig. 2 a vertical section of a modification Referring to Fig. 1, 11 is the electrolytic vat, 12 a frame supporting the mirror or mirrors, 13 a frame carrying the anodes. The frame 13 hinged to one of the sides of the vat so that it may be folded down to bring it; parallel to the bottom of the at and therefore to the, mirrors during the the positing process; on the other hand when the apparatus is to be put out of work the frame 1; may be brought into the vertical position; the frame 12 is constructed to dosccnd into the vat \vhile renmining horizontal, or approximately so, when the frame 1? is turned downward so that a single operation serves to put; the whole apparatus Specification of Letters Patent.
in working condition. For this purpose the frame 12 has at one end rollers 1-1. adapted to roll on an inclined plane 13 fixed at that side of the bath which is opposite to the hinges carrying the frame 13. At the other end the frame 1'2 carries pins or the like adapted to engage in hooks It; on the ends of rods 17 fixed rigidly to the frame 1 One limb of the hook 16 is longer than the other to facilitate introduction of the pin carried by the frame 12. it will be obvious that when frame 13 is lowered into the horizontal position, frame 12 will accompany it desccndinginto the vat l1, and that in order to raise the frame 12 from the vat it is only necessary to lift the frame 13-3 into the vertical position.
The dotted lines, Fig. 1. show the relative positions of the frame carrying the. mirrors and that earryii'ig the anode at a certain time of the manipulation of the mechanism. As shown by these dotted 'lines the mirrors are completely immersed before the anode 9 has begun to enter the bath, whose level is indicated by a;'-;r.
The current is conducted to the silvered surface by means of any suitable device such as the clamp 18, connected by a flexible eon ductor. through a copper bar 19 fixed to the outer surface of the wall of the val, with the negative pole of the current. generator while the frame carrying the anode is connected with the positive pole.
The connection of the flexible conductor with the bar 19 may be any that is suitable, thus the end of the conductor may be insorted beneath the screw or into a spring blade contact The, frames 12 and 1;) may he of any suitable dimensions being limited merely by the dimensions of the vat. 'hen the latter is of very large dimensions it is prefe'able in practice to combine one vat with two or more frames, 12 and l3, so that the latter. may not be of very large dimensions requiring powerful machines for moving them.
in the umd lieation shown in Fig. 2 instead of rollers ll rolling on an inclined plane 15 the frame 12 has pins 8 or the like, adapted to engage in books on the ends of lovers (3 pivoted at; T in the vat.
llaving now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, l declare that what 1 claim is:---
l. in apparatus for electropiating mirrors, a vet, an anode pivoted on said vat, a mirror carrying frame, pivoted at one end on said anode, at a suitable distance from the latter, and means for supporting and guiding the other end of said mirror carry- 3; In apparatus forelectroplating mirrors, a vat, an anode pivoted on said vat, a mirror carrying frame, pivotally supported on one end on said anode frame, at a suitabledistance from the latter, and levers, pivoted on said vat, and the free ends of which engage suitable devices carried on the frame, substantially as described.
In testimony whereof, I have signed my name to this specification in the presence of two subscribing Witnesses.
