Specification of Letters Patent.

Patented May 19, 1908.

To all whom it may concern:

- Be it known that I, JOHN T. DANIELS, a citizenof the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Im rovements in Electroplating Apparatus; an I do hereby declare the following to be a full, cl'eanaudexact descri tion of the invention, such as will enable t ers skilled in the art towhich it appertainsto make and use the same, reference being had to the accom panying drawings, and to characters of reference marked thereon, which form a part of this specification.

This mventionrelates, generally, to improvements in apparatus for the electrO-dep- 'osition ofmetals upon various articles; and,

the present invention is in the nature of an improvement in that class of electro-plating a paratus comprising a tank or vat in which t e electrolyte s contained and inwhich is placed a'rotatable drum, cylinder or basket, ordinaril termed the container, and in which the artic es which are to be plated are placed,

the container being supported upon contactbrackets or so ports extending from the si ea or ends oflt e, tank, and the container being provided with means for lower-. ing and raising the said container, so that the container or basket-carrying frame will make.

or breakelectrical connection with the said contact-brackets or supports.

The invention, therefore, has for its princi pal object to provide a novel and simple a'rrangement of the contact-making bracket or'.

. support-for the removable-container or haske't of an electro-plating apparatus, all-er ranged that a positive electrical contact will be made between the parts of the container or basket and-the means forsupporting the same 1n Its o erativerelation'within the tank or vat of t e'ap aratus. Q

A further 0 j'ectof this invention is to pro- -der-or basket being supported by means of a suspensionsjframe, which is provided with means which is adapted, as the di'um, cylin der or basket is lowered into the electroplating solution, to automatically register with contact-teats or projections,

withm the tank or vat, while making elecde an apparatus :of thegeneral character so as to er-' said bars or rods being ,fectly centerthe drum, cylinder-or basket lateral displacement, whereby the process of electro-deposition might possibly be interfered with. a

Other objects of this invention notat this time more particularly enumerated will be clearly understood from the following detailed description of the present invention.

The invention consists in the novel electrolating apparatus hereinafter set forth and, iiirthermore, this invention consists'in the novel arrangements and combinations of devices and-parts, all of which will be heroin after more fully described and then finall embodied in the clauses of the claims which are appended to and which form an essential part of-this specificatlon.

The iIfYGIltlOIl is clearly illustrated in the accompanying drawings, in which Figurel is a plan or top view of one form of electroplating apparatus rovided with a, revoluble contalner'mounte in a suspension frame adapted" to be brought in supporting engagement with the contact-making brackets or supports, all embodying the principles of this invention; Fig. 2 is a transverse section, on an enlarged scale, said section being taken on line 2.2 in said Fi 1, looking in the direction of the arrow-ac, t e tank or vat and some of the other parts, however, being Omitted from said View; and Fig. 3 is a crosssection, on still a larger" scale, said section bein taken on line 33 in Fig. 2, looking in the irection of the arrow 1 said View showing, in connection therewith a transverse sectional representation of a portion of the tank or vat and the contact-making bracket or sugport.

lmilar characters of reference are em ployed in all of the above described views, to indicate corresponding parts.

Referrin now-to the said drawings, the reference-c aracter 1, indicates a suitable plating tank or vat, comprising the sides 2 and ends 3, all of which are suitably con-. nected and may be tied by means ofthe usual tie-bolts 4.

The reference-character 5 indicates suitably disposed anode-bars or rods, in the present drawings two of such bars being shown,

provided with contact-elements or fixtures 6, having a connecting circuit-wire or rod 7 between them. An
