Be ity known that LCLARENCE E, LEEFEr., a resident of .Meadville, in the county of Crawforda'nd State of Pennsylvania, have `invented a new and useful Improvement in lllectroplating-Racks, of which l'the yfollow- This invention relates to racks `o`r` hangers kforuse in electroplating metal articles, and

more particularlyf" to cathode hangers for .electroplating y In electroplating all bare metallic surfaces connected with the cathode and immersed in the bath or solution receive a deposit of the metallic and consequently the metallic supports which hold the work or convey the current become heavily coated. This coating is practically wasted or, at least has to be recovered at considerableexpense, and in addition to this its depositionl involves a wasteful consumption of current.'

The object of my invention is to reduce toa minimum the bare surface of the rack outside of that necessary to make a proper electrical contact with the article to be plated. It also provides for holding all parts of the work to be plated practically equidistant from the anode so that all portions of the'article are uniformly coated.

The invention comprises a rack constructed and arranged as hereinafter described and claime In the accompanying drawing, Figure l is a sectional view of a portion of an electroplating tank showing one of the racks in position; Fig. 2 is an end view of the rack; and Fig. 3 is a side elevation thereof.

In the drawings, the electroplating tank is shown at l and the cathode conductor at 2. Theanode is not shown, but preferably there will be two, one on each side of the cathode', as will be readily understood by those skilled in the art.

The rack comprises two similar side members 3 and cross-connecting members L Each side member comprises a .body 5 of non-conducting material, such as wood. although 1f desired 1t may be fiber, porcelaln or other non-conducting y mater1al.4 The crossconnccting parts tare shown in the form of metal ducting support for the a good electric connection,

vsively coated attachment to or @detachment from the cathode conductor 2. On each side face `of the body 5'is a member Sjserving as aconarticle, these being in the form of strips of copper, brass or other good conducting materlal and having the article supports provided by bending the same to form projectionsf9, lpreferably inclinedupwardly. These members 8 `are connected tothe hooks 7 jin` a manner` to give of rivets 10 and are detachably connected to the insulating body 5, such as by means of nails or screws-11. Consequently, when they become excessively coated, theyv can be such as-by means readily removed and be replaced by new l strips.

The articles to be plated are laid upon the projections 9 of t-he two side members. The projections on the same side of the rack lare in line with each other, While, prefera'rranged in alternate relation with` ably, those on the opposite side of the rack, as shown.

The rack described provides for holding all articles a uniform distance from the' anode in a manner to practically expose all parts of the article and secure a uniform coating. The construction is such that when the article supporting members are excesthey can be replaced at a ver low cost fory labor and material. y A

What I claim is:

1. A cathode hanger for electro-plating,

comprising a 'non-conducting body, a conducting hanger therefor, and a conducting support detachably connected to the body, andi electrically connected to the hanger, the sai provided with a pluralityof integral supporting projections.

. 2. A cathode hangerV 4for electro-plating comprising a non-conducting body, a conducting hanger therefor.,l and a conducting strip detachably connected to the body and electrically connected to. the hanger, said conduct-ing 'strip being provided with a series of work supporting projections in permanent and intimate electrical therewith.

3.' A cathode'A hanger for electroplating, comprising a nonconducting body and a conducting hanger therefor, and a conducting strip bent to provide a seriesof'supporting projections detachablyconnected to the support comprising a conducting strip connection .Q Y L? body and i electrically connected to the hengel- 4. A cathode hanger'for electro-plating, comprising a pair of members each comprismg a non-conducting body, a conducting hanger therefor, and conducting supports detachably connected to the body and electrically connected to the ,'hanger, and cross members connecting said non-conducting bodies.

comprising a non-conducting body, and a yContact stri detachably secured thereto and provided with a plurality of integral Work supporting projections.

. 6. A cathode Vhanger for electroplatillga Copies of this patent mafy be obtained for 5. A cathode hanger for electro-plating,

comprising a pair of oppositely arranged conducting strips bent to provide a series of supporting projections,

port for said strips.

7. A. cathode hanger and a suitable sup- :Eor electro-plating,

comprising oppositely arranged conductlng strips bent to provide av series of supporting projections,

and a suspending member connected to the upper ends of said strips.

In y'testimony whereof, I have hereunto set my hand.
