'1 the preparation of j electrotypes, the
mo ds or cases of wax; or similar material are co' 'ered "with graphite or; black lead; and are usually-treated with a;solution of 5 copper-sulfate a'nd'iron filings. This has theefi'e'etof inereasing the conductivity of the case so that plating almost imme dia t ely uponimmersionin theiplafiing bath. 7 The use, of ,blue stone or" cop er sulfate and; iron 'filin'gshas inany draw acks, chief of which is a tendency tos'cratchthe faceof th1case the undi'ssolv'edpiec'es'of th'e'i'ron egsolution is'exgensive and; very,

In' practj'cing my 'proeess atethispoint, I iminerse the case. in a '801-1ition of-dpyrogalho nerd, which is an or anie'acidan an oxygen acid of the ca rbocyc ic Series. I prefer to use pyrogallic acidfthough 1'; they use tannic acid, gallotannic' 8cid' )l.:g &1 l1' i11d for th'e same Th -mi is p i 1 5 by .tlie as described int e acid Application and J un'e 9,; 90a." ser al-11o. secede.

{contains ahout SO grains to the gallon of ',;water.- After'treating the'case with the acid' I -fspra it again with the nozzle, to
I rinse the acid from the face of the, lead.
The ca is then placed inlthe plating bath.
'It'i's ve'r important that'the cases should be thoroug y washed, sothat all; of the acid or =1ts' pro ucts will beremoved. ,Ifthis is not accomplished, the acid remains in the recesses of type, increasingthe resistance in its locality; this produces spots and destro'ysthe. uniformity of.- the resulting late.
it is the effect of the treatment with th-eiacid which is desired rather than the presence of ftlmes by ink which a erefs to the type after For this reason it should be understoo that the acid itself. In this connection it should taking prboflsheets fromlthe' form. I beheve'; also, that the tendencytoform spots is a avatedby the presenceof lighter oils v wi i h come to the surface of the wax under the great pressure .to which the cases are I subjected. "The acid dissolves these sub 'stanceswhenfia'pplied to the"lcase,-'and the surface of the'casebecomes'. thorou hl'y clean when-rinsed" with water as ldes'cri'ed. Thje faction of the acid appears-to be' to prevent thelafpgearancelon the surface .ofthe case'ofbubb e of occluded gas,- and 'itl-is thought that it has agcertain advantageous actlonuponthe lighter foil's which may- .hebrought to the surface ofthe wax by the pressure. -What'I claim and desire tosecurel Letp I ters Patent is:
