HANGER FOR ARTICLES TO BE PLATED Filed Oct. 3, 1929 1 INVENTOR.

/ Lou/5 Z/CHTM/m/ Patented Oct. 13, 1931 UNITED STATES PATENT OFFICE LOUIS LICHTMAN, NEW YORK, N; Y., ASSIGNOR TO CHROMEPLATE, INC., OF NEW YORK, N."Y., A CORPORATION OF NEW JERSEY HANGER FOR ARTICLES TO BE PLATED Application filed October 3, 929. Serial Ito/397,028.

This invention is an improvement in hangers for articles to be plated, and more particularly'in a hanger for chromium dplating,

enabling the article to be supporte in the most favorable position for receiving the deposit.

In plating articles, such as spoons and the like, it is somewhat difiicult to obtain good contact between the article and the cathode, with a minimum of contact, and to support the article firmly against liability to displacement.

Wherever there is contact between the article and the. support for the same, which is 'electricall connected with the cathode, the

portion 0 the article covered in the contact is not coated. For this reason, it is desirable that the article be supported in such manner that it may be moved slightly during the deposition to expose the surface formerly covered in the contact.

One of the primary objects of the present invention is the provision of a hanger, ofa

nature such that close contact is provided between the hanger and the article, while at the same time the article may be moved with respect to the hanger during the plating operation, to expose the surface previously covered to the action of the electrolyte.

Another object is the provision of a hangerin the form of a one piece conductor, of a character such that the resiliency thereof is not materially im aired'by use.

Another object is the provision of a hanger wherein contact with the article is made at opposite sides thereof, at points spaced apart from each other, and resiliently to enable good conduction with the capability of manually moving the artiole for the purpose above mentioned. I

Another object is the provision of a rack,

of simple inexpensive construction adapted to support a maximum of articles in aminimum of space.

With these and other objects in view the invention consists in the'construction and novel combination of parts fully described hereinafter, illustrated in the accompanying drawings, and pointed out in the claims appended hereto, it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims, may be resorted to without departing from the spirit of the inven-.

tion.

In the drawings forming a part hereof Fig. 1 1s a transverse vertical section of a tank provided with the improved hanger.

T Fig. 2 is a perspective view of one of the cross bars with hangers or holders connected therewith.

Fig. 3 is a plan view of apart of a cross bar with a modified form of holder or hanger.

The present embodiment of the invention is shown in connection with the plating tank 1 of usual construction, having one or more cross bars 2 extending across the tank, either longitudinally or transversely, and adapted to support the rack, having hangers in accordance with the present invention.

The rack comprises a substantially U- shaped frame, composed'of a body 3, and arms 4, each arm having a hook 5 at its upper end for engaging a cross bar, so that the hanger depends into the electrolyte in the tank. The arms 4 are connected at suitable intervals by cross bars 6, and the cross barscarry the holders or hangers of the invention.

Each of these holders or hangers is a substantially U-shaped member, formed of wire of suitable gauge, the wire being bent to form an 0 en ring -or loop 7, with the arms Sextendlng along side each other in spaced relation from the ends of the ring. The ends of the arms remote from the body are soldered or-otherwise secured a) a cross bar 6, the connection, being indicated at 9.

Each arm is provided, near the ring 7, with I is turned. at substantially right angles in the dotted line position shown in Fig, 2.

The arms are so spaced that the bottoms of the notches are distant from each other less than the width of the article tobe held, and the material of the holder is resilient, so that when forced apart as above mentioned, they will grip the article firmly through their resiliency, holding it against accidental displacement, but permitting movement thereof when sufficient force isexerted. 1

In Fig. 3, the holder is slightly difierent in form, being designed to support two articles, or to support a single article in either of two positions. In this arrangement, the holder is of wire bent into U or hair-pin shape The arms 1270f the holder extend along each other in spaced relation, to a connection 13 with the cross bar it of the rack, Each arm has an outwardly bent portion 15 near the end remote from the cross bar, the outwardly bent portions 15 cooperating to form a ring or lo'o'p open atopposite sides.

At each sideof the ring or loop, each arm has outwardly bent portions 16 and 17, respectively, forming notches similar to the notches 10 of the arms 8, and similarly spaced. The corresponding notches are in register, and it will be apparent that two articles may be supported, one by the notches 16 and another bythe notches 17, or either set of notches may support a single article.

What is claimed as new is 1; In a device of the class described, a holder for articles to be electro-plated, com-' prising a substantially U-shaped member including resilient arms lying alongside each of U-shaped members, each member including arms lying alongside each other and connected at one end, the other ends of said arms being connected to the bar, said arms having cooperating means to engage the opposite edges of an article to be plated, and- .having registering outwardly bent portions transverse to the length of the arms, and the other and connected atone end, the other ends cf the arms being adapted for connection with a support for the member, said arms having cooperatmg means near thelr said connection to engage the opposite edges of an article to be plated, and having registering outwardly bent portions adjacent to said means to facilitate the engagement of the article therewith. I

2. In .a device of the class described, a

- holder for articles to be electro-plated, comother pair being adapted to grasp the ed es of the handle, when it has been slipped etween the arms with its plane in the direction of the length thereof, and turned transverse- 1y to the arms.
