Original application filed February 10,
To all whom it may concern:
Be it known that 1, ROBERT L. WHITE- HEAD, a citizen of the United States, residing at Perth Amboy, county of Middlesex, and State of New Jersey, have invented certain new and useful Improvements in Electrolytic Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to certain new and useful improvements in electrolytic apparatus, and particularly to the arrangement of the electrodes in such apparatus and the connections for maintaining electric contact of an eflieient character and of low resistivity throughout the system.
Prior to my invention, it has been customary in electrolytic apparatus for the deposition of metal from solutions (as, for instance, in the electro-metallurgy of copper, nickel, and the like) to arrange the electrolytic vats containing the solution to be electrolyzed, alongside of each other, and in such relationship that the working current entered a bus-bar, with which the anodes of the first vat of the series connected. From these several anodes, the working current then passed through the solution to the several cathodes of said vat, thereby electrolyzing the solution therein. The cathodes of the first vat, in these prior arrangements, rested upon and made elec-- trical connection with a supporting bar, which, in its turn, supported and made electrical connection with the anodes of the next succeeding vat in the series. The main defect in this general arrangement has been that it involved a double series of electrical contacts along the common bar supporting the cathodes of the first vat and the anodes of the second vat, and so on, through the series. This difficulty is of particular importance in electrolytic apparatus, for the reason that the working current employed is of relatively low voltage, so that the total loss of energy due to the large number of individual contacts called for in an extensive installation is very considerable in amount and importance.
My present invention is intended to minimize this loss of energy by connecting the cathodes of the first vat of the series di- Specification of Letters Patent.

' tween the cathode of one of the vats and the anode of its neighbor in the series; Fig. 4: represents a top plan view thereof; and Fig. 5 represents a sectional view on the line 5-5 of Fig. 3.
Similar letters of reference indicate similar parts throughout the several views.
Referring to the drawing, A indicates the individual members of a series of electrolytic vats, forming part of an installation for electrolytic purposes, as, for instance,
the deposition of metal from its solutions,
by means of an electric current of low The anodes a are provided with supporting lugs 19, 0, for suspending them in the solution. The lugs 72 of the anodes rest upon the bus-bar B, which supplies the working current to the apparatus, and the lugs 0 rest upon an insulating strip d,
.as shown. The cathodes e are likewise provided with lugs f, connecting them to the bar 9, which is thus electrically connected with and constitutes a part of the cathode structure, and the ends ofthe bar 9 constitute the supports from which the cathode is suspended in the solution. One end of the cathodes rests upon the insulating strip h, and the opposite end rests upon the supporting lug b of the corresponding anode in the next vat of the series. It willbe apparent, therefore, that, instead of the double set of contacts incident to the use of the common connecting bar of the former arrangement herein before referred to, an electrolytic apparatus provided with my improvements has but a single set of connecting contacts between the cathodes of.
the several vats and the anodes of the corthat is to say, the single contact established that? there isa corresponding saving in energy of one-half of the loss incident to.
the usual practice.
It will be particularly noted that my preferred connection between the cathode and anode is a Wedging contact. The preferred form of this connection is fully indicated in Figs. 3, 4 and 5, and, as shown therein consists of a ridge or projection 2', cast integral with the lug b, cooperating with a recess j made onthe underside of a boss K of the cathode bar 9. This recess 7' is so related to the ridge or projection i that the side walls of the recess shall come in wedging contact with the sides of the ridge or projection, and, to this end, a corresponding clearance is provided, as indicated in Figs. 3 and 5. The relative conformation of the ridge or projection and of the recess permits of this wedging contact. In the instance illustrated, the result is attained by making the angle of the recess smaller than the angle of the entering ridge or projection, but it will be understood that this is merely one of many other like or equivalent expedients for producing the same result, that is to say, of causing a binding or wedging contact on opposite sides of the ridge or projection and between said sides and the lower edges of the recess.
I do not claim herein the form of the contact above described including the provision of a wedging effect by the employment of a ridge or projection on one of the coacting parts and a recess or groove on the other, as that form of contact constitutes the subject matter of another application filed by me on .February 10, 1913, and serially numbered 747,253, of which this application is a division.
