This invention is an improvement in racks or hangers for articles to be electro-plated,
- and more particularly in a rack or hanger for supporting plate-like articles, in such manner as to leave substantially the entire surface thereof exposed, and with a good electrical contact between the rack and the ar- In order to obtain a smooth and even deposit on plate-like articles, it is essential that the surface of the article be exposed to. the deposit throughout the entire area, while at the same time electrical contact must be maintainedbetween' the article and the rack. v
- One of theprimary objects of the present invention is the provision of a rack or hanger especially designed for supporting articles of this character, withsubstantially the entire surface thereof exposed, andwith close contact between the article and the rack or hanger.
Another object is the provision of a rack havin members, resilient and laterally displacea le to facilitate the insertion of an article, and so arranged that the insertlon of each article braces the resilient member of the preceding article against lateral displacement.
Another object is the rovision of a rack wherein the resilient an laterally displaceable members act to cause the angers to tightly engage the articles when they are in place-in the rack. r With these and other ob ects 1n 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 fromthe spirit of the inven- .tion.
In the drawings forming a part hereof Fig. 1 is a transverse vertical section of a plating tank provided with the improved hanger;
Fig. 2 is a detail '1l 1 perspective of a part to-oftherack.
"The present embodiment of the inventionis shown in connection with a plating tank 1 of usual construction, having the usual cross bars 2, extending transversely or longitudinally of the tank, from which the racks or hangers are suspended, the'cross bars resting on the tops of opposite walls of the tank, and being the circuit.
The improved rack includes a substantially U-shaped frame composed of a bottom memher 3 and side members 4 extending upwardly from the bottom member, and each provided at its upper end with a hook 5 for. engaging a cross bar 2.v The side members 4 are connected atsuitable intervals by. cross bars 6 o f relatively small cross section, and of res1l1ent material. The cross bars are riveted or otherwise secured to the side members 4, as indicated at 7, and each cross bar 6 .and the bottom member 3 carries a set of hangers for engaging the articles indicated at a, to be plated.
Each of the hangers is of substantially U-shape, comprising a body 8, which is soldered or otherwise secured to a cross bar 6, as indicated at 9, and arms 10, extending from the ends of the body. The arms extend from the body at' an obtuse angle, as shown, and each is provided at its outer end with an angular portion 11, which is notched as indicated at 12 for ascribed. I
The angular portions 11 are substantially perpendicular to the cross bars 6, and to the bottom bar 3 of the frame. Referring purpose to be de- 'to Fig. 1, it will be seen that the hangers of the bottom member 3 of the frame are opposed bya set on a cross bar 6, and a set on the o posite side of this crossbar 6,are opposed y a set on another cross bar.
connected to the negative lead of The bottom member 3 of the frame is sub I stantially rigid, but the cross bar justv above it 1s resiliently displaceable away from the member 3 to enable insertion of an article.
The second cross bar from the member 3 is also displaceable in the same manner, but
when an article has been placed between the lowest cross bar 6 and the next lowest it braces the lowest cross bar against lateral displacement, so that'the article between the lowest cross bar and the member 3 is tightly I I clamped by the hangers.
In use, a plate is first inserted between the bottom member 3 and the adjacent bar 6, the said bar 6 bein sprung upward inter-.
mediate its ends to. acilitate the insertion ofthe plate, and the plate-is held by its edges in the notches 12. Another plate is now in-j serted between the, lowermost bar 6 and the next 11 per in the same manner, the next:
upper ar being-sprung to enable the insertlon of the plate.
It will be apparent that, the insertion of the second plate locks the first plate in place, acting as a brace to prevent springing of the lowermost bar 6. Practically the whole surface of the articleis exposed to the electroe plating action, while at the same time good electrical connection is provided between the article and the rack,- to which the negative lead isconnected. The tank is provided with 4 the usualanodes to which the is connected.
positive lead It will beapparent that the members 8- l0-11, which engage the articles, contact with the articles only at the corners of the edges This is due-to the -V-shapeof the notches 12. The articles are slidahle longi tudinally i'n'the members 810-'-11, so that" if desired, they may be shifted longitudinally toexposethose minute portions which have been engaged by the said members. 7
