ELECTROLYSIS SUSPEIfiION I HOOK.
Specification of Letters Eatent. Pg tgnted Apr, 18, 192,2.
Application filed April 22, 1921. Serial No. 463,510.
To all whom it may con-scam:
Be it known that l, EDMUND Vole-r, a citizen of the United States, residing at 112 1: N. Dearborn Street, Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Electrolysis Suspension Hooks, of which the fol lowing is a specification.
My inventionrelates to improvements the so-called hook for suspending in a tank-containing electrolyte, from conducting-rods supported to extend transversely across the tank, the cathode and anode.
Two main objects are accomplished by my improved construction of the hook, which enables the supply of current to be nicely regulated to the requirement of the work to be done, and the hook to be longitudinally adjusted to lengthen and shorten it for immersing the cathode and anode to varying depths in the electrolytic solution.
In the accoinpanying drawings, Figure 1 is a broken perspective View illustrating a tank for the solution, equipped for electrotyping, the equipment involving hooks of my improved construction; Figure 2 shows the hook in side elevation as suspended on a conductor-rod and connected with an ammeter, the latter and the rod'and also a case (block forming the cathode) being shown in dotted representation; Figure 3 shows the hook as in Fig. 1, but partly in longitudinal section; Figure i is a view of the hook in front elevation; Figure 5 is a similar View of that part of the hook in volving the metal hanger-head and longitudinally slotted stem extending from it, and Figures 6 and 7 are sections respectively on lines 6-6 and 7-7, Fig. 3.
I have more especially designed my improved device for use as an electrotypers case-hook; but it is equally useful, with the same advantages, as a suspension-hook for electroplating generally.
On the tank A (Fig. 1) are provided the usual current conductors B and C, which are included in an electric-generator circuit (not shown), and the conductors B- and G extending across the tank respectively from B and G and on which are suspended the hooks, for carrying, immersed in the electrolytic solution, one the cathode, or case D and an adjacent one the anode D.
The suspension-hook, whichis designated as a whole in the drawings by the referenceletter E, has a metal head 8, of hook-like form for hanging it on a rod B or C, a handleS extending upwardly from the head by means of which to manipulate the hook, and a slotted metal stem 9 extending from the head and encased in or covered by insulating'lnaterial 10, which maybe guttapercha or any suitable composition; and a metal bar 9 forming an extensible'and retractable section of the stem 9, is adjustably fastened against the rear face of the insulation 10. At 12 is represented on the head 8 a rheosta-t having one terminal connected by an insulated conducting-wire 13 with a binding-post at 11 on the bar 9 and the other terminal connected through an ainineter, indicated at F, with a binding-post 11" on the head 8 to lead current from the conductor B through the rheostat and the ustabl section of the hook E to the cathode or case D. I
For adjustably securing the bar 9 in place, a'bolt 14 passes through it and the insulation and through the slot in the stem 9 anda washerlotherein, and carries on its threaded end awing-nut 1%. The bar 9 terminates at its lower end ina pair of cars 16 carrying pivotally between them a depending shoe 17 to be yieldingly pressed into close contact with the face of the case D by a spring 18 rigidly fastened to the bar 1 9 by a bolt through the latter and the solid lower end of the insulation.
For carrying the cathode or anode on a hook E it is hung, at holes provided therein, on a pair of hornlike hangers 19 extending forwardly on the lower end of the hook.
lit is the practice in the electrotyping art to suspend a plurality of cases D in the solution to be elettrotyped simultaneously, and these are liable to be of various sizes some presenting larger and some smaller surfaceareas, and the amount of current required for the work varies with the extent of surface-area. lVhere an excessive amount of current is used, not only does waste thereof ensue but the electro-deposited shell contains blisters and tends to peel off, spoiling the work and requiring it to be done ever. My improvement avoids these objections by enabling the quantity of current to be nicely regulated according to the requirement for each piece of work. Then by reason of these varying surface-areas, hooks of different l ngths have to be provided for immersing the cathodes and also anodes of varying dimensions to the proper depth in the soluscribed, having a current-conducting section and shortening it.
tion, thereby requiring a plurality of the hooks of different lengths to be provided, always ready at hand. The adjustability of my improved hook adapts it forthe'requisite immersion to any desired depth, by lengthening or shortening the hook upon loosening, the bolt 14: to enable the bar 9 and parts carried by it, including the insulation 10, to be lowered or raised, the Wingnut 1 rserving to fasten the parts in their ad 'usted relation,
I realize'that considerable variation is possible in the details of construction herein shown and described, and I do not intend by illustrating a single specific or preferred embodiment of my invention to be limited thereto, it being my intention in the following claims to claim protection for all the novelty there may be in my invention as fully as the state of the art will permit.
