page_text: LETTERS PATENT to Henry Mathieson of Mile End in the County of Middlesex
Lithographer for an Invention of "IMPROVED MEANS OF DRYING BY COLD
PROCESS PRINTING ON TIN, ZINC, BRASS, OR OTHER METAL"
PROVISIONAL SPECIFICATION left by the said Henry Mathieson at the
Office of the Commissioners of Patents on the 18th March 1882,
HENRY MATHIESON of Mile End in the County of Middlesex, Lithographer
"IMPROVED MEANS OF DRYING BY COLD PROCESS PRINTING ON TIN, ZINC, BRASS,
OR OTHER METAL
"
My invention relates to drying by cold process printing on tin, zinc, brass, or
other metal. Hitherto lead has been the dryer of ink used for printing on metal.
In carrying my invention into practice I provide two ounces of Borate of Manganese,
and two drachms of Sulphide of Manganese which I boil for two hours in one
gallon of Linseed oil. I scum the oil when necessary during the boiling process.
The oil having been allowed to cool I mix the dregs thereof with a convenient
quantity of Frankfort-Black ground, pounded, or mixed, and I thus obtain a thick
paste. To render this paste easy for printing when applied to the printing-roller I
mix with said paste a convenient quantity of said boiled oil. For printing light
colors it is necessary that the aforesaid paste should be "tacky," or more elastic
than for printing dark colors. To effect that result I boil for two hours longer the
oil herein before mentioned, and I mix it with the paste above mentioned.
the quantity of dregs is insufficient I add thereto a sufficient quantity of the oil
boiled for four hours, and which is usually known as "strong oil." By this means
I obtain the requisite quantity of paste. I coat the sheet of metal with the paste
hereinbefore mentioned, and I dry the printing on said sheet (which printing is
executed in the ordinary manner) by exposure to the atmosphere instead of by hot
air or heating process as bas been employed hitherto. By my invention I obtain
the following advantages namely the sheets of metal when so printed will stand
ordinary wear without being varnished, and not being varnished will more readily
receive solder when they are being manufactured into shape.

My invention relates to improved means of drying by cold process printing on
tin, zinc, brass or other metal.
Hitherto lead has been the dryer of ink used for printing on metal. In carrying
my invention into practice I provide two ounces of Borate of Manganese, and two
drachms of Sulphide of Manganese which I boil for two hours in one gallon of
Linseed oil. I scum the oil when necessary during the boiling process. The oil
having been allowed to cool, I mix the dregs thereof with a convenient quantity of
Frankfort-Black ground, pounded, or mixed, and I thus obtain a thick paste. To
render this paste easy for printing when applied to the printing-roller I mix with
said paste a convenient quantity of said boiled oil. For printing light colors it is
necessary that the aforesaid paste should be, "tacky," or more elastic than for
printing dark colors. To effect that result I boil for two hours longer the oil
herein before mentioned, and I mix it with the paste above mentioned. When the
quantity of dregs is insufficient I add thereto a sufficient quantity of the oil boiled
for four hours and which is usually known as "strong oil." By this means I obtain
the requisite supply of paste. I coat the sheet of metal with the paste herein-
before mentioned, and I dry the printing on said sheet (which printing is executed
in the ordinary manner) by exposure to the atmosphere instead of by hot air or
heating process, as has been employed hitherto. By my invention I obtain the
following advantages namely the sheets of metal when so printed on will stand
ordinary wear without being varnished and not being varnished will more easily
receive solder when they are being manufactured into shape.
Having now fully described the nature of my said invention and the manner in
which the same is to be carried into effect I wish it to be understood that what I
consider new and therefore secured to me by the herein before in part recited Letters
Patent is substantially as is set forth in the foregoing specification In Witness
whereof I the said Henry Mathieson have hereunto set my hand and seal this
Thirteenth day of September in the year of our Lord One thousand Eight
Hundred and Eightytwo
