PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Printing Surfaces.
I GIBBARD RICHARD HUGHES of 77 Leadenhall Street in the City of London,
Printer do hereby declare the nature of this invention to be as follows:-
To render the lines or type-surfaces cast or made by the Linotype or similar
or other composing machine harder or capable of greater wearing power than is
possible or economical as the lines or type surfaces are now cast, I propose to coat
or cover them by the electro deposit or other suitable process with a harder metal
such as copper or tin or other suitable material. To enable me to so coat or cover.
them cheaply and economically I propose to carry them automatically or by other
convenient means through the solution or other arrangement employed so to cover
or cont them.
Dated this 7th day of November 1895.
GIBBARD R. HUGHES,
I GIBBARD RICHARD HUGHES of 77 Leadenhall Street in the City of London
Printer do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
According to this iuvention I render the lines or type surfaces cast by the
Linotype or similar or other composing machine harder & capable of greater
wearing power by coating or partially covering them with a harder metal than can
be used for casting them.
To enable me to coat or cover them economically I drill or punch one or more
holes in each line cast or in several lines at one operation. Into these holes I pass
a rod with or without a screw head at one end & a screw thread at the other. A
column of lines can thus be passed into the bath or tank as a solid block, & left
until a sufficient deposit has accumulated upon their printing surface or upon that
greater part of their surfaces as is considered necessary.
By another method I arrange the lines together as taken from the casting
machine & plane as otherwise cut a longitudinal groove or indentation at either
end into which a tongued side stick or frame may be fitted or by which the lines
may be passed along guiding-rails into & held in the bath or vat until the deposit
has been accumulated by the electro-deposit or other convenient process.
The drawing annexed will show both arrangements more clearly.
No. 1 gives the side view of a linotype or solid line of type A. A. At B B two
holes have been pierced or cut through the body A. A. C. is the printing surface
in Nos. 1, 2 & 4.
No. 2 shows several lines so pierced and after the screwed rod or pin has been
passed through them and screwed into the further line K thus holding them
together in the form of a solid block.

page_text: No. 3 shows the screwed rod or pin detached.
No. 5 shows the section of the tongued side stick or rail.
No. 4 shows a linotype with the side slots to fit the tongue J.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
] claim is:
1. The coating of the printing surfaces of linotype lines as above described.
2. The piercing of holes in such lines & the insertion of a pin or other device
for holding them in a solid block while they are being so coated or for any other
purpose.
3. The side slots in linotype lines for the purposes above explained.
Dated this 7th day of August 1896.
