UNITED STATES PATENT OFFICE.
MARSHALL E. STEWART, OF PERTH AMBOY, NEW JERSEY, ASSIGNOR TO THE ROESSLER & HASSLACHER CHEMICAL CO., OF NEW YORK, N. Y., A CORPORATION F NEW YORK.
ANODE.
Application led March 10, 1922.
To NZZ 'whom t may concern:
Be it known that I, MARSHALL E. STEW- ART. a citizen of the United States, and resident of Perth Amboy, in the county of Middlesex and State of New Jersey, have invented certain new and useful Improvements in A\nodes, of which the following is a specification. y
This invention relates to improvements in anodcs for electroplating baths.
'l`hc object of this invention is to provide au anode having a large surface area. in proportion to the cross sect-ion of metal involved and thereby facilitating the plating operation and in addition witha cross section of such shape that the decrease in weight oi' the anode during use is not accompanied by a proportionate decrease in thcl surface ot the metal exposed.
'ith the above object in view the invention consists ot certain novel features of construction as hereinafter described and claimed.
In the accompanying drawing Figure l is a transverse sectional view of the anode constructed in accordance with the invention; Figure 2 is a side view of the same.
Referring more particularly to Figure l it will be seen that the projections increase thc working surface greatly over the cylindrical form of anode commonly used and thcrchy greatly increase its capacity for depositing metal. It will also be evident by rclcrcucc to Fig. l that the wasting away of this anode will not weaken it structurally or Serial No. 542,646.
greatly decrease its available surface until the greater portion of the anode has been dissolved. The anode is substantially in the form of a cross, each arm of which is one and one half inches long and three-quarters of an inch thick, giving the ratio of 1:2 between the thickness of the arm and its length. In order to adapt this form better to plating operations, we have eliminated sharp edges. The ends of the arms are, therefore, curved, giving convex and the sharp corners formed on the intersections of the arms are eliminated by a llet as shown in the drawing. The anode may be made of any convenient length from end to end depending upon the depth of the tank in which same is to be used.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
l. As a new article of manufacture an anode whose cross-section is in the form of a cross in which the length of each arm is approximately twice its thickness, substantially as shown.
2. As a new article of manufacture an anode whose cross-section is in the form of a, four-arm cross in which the length of each arm is approximately twice its thickness, all corners and fillets thereof being rounded substantially as shown.
Signed at Perth Amboy, Middlesex and State of New day of March, A. D. 1922.
