Year: 1871

page_text: LETTERS PATENT to William Laycock, of Church, in the County of
Lancaster, for the Invention of "IMPROVEMENTS IN CALICO PRINTING
MACHINES.'
Sealed the 24th November 1871, and dated the 25th May 1871.
PROVISIONAL SPECIFICATION left by the said William Laycock at
the Office of the Commissioners of Patents, with his Petition, on
the 25th May 1871.
I, WILLIAM LAYCOCK, of Church, in the County of Lancaster, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
CALICO PRINTING MACHINES," to be as follows:-
The object of this Invention is to make all the rollers and bowl of
the printing machine, whether the rollers are used continuously or
intermittently, positive in their motions so that there shall be no
> possibility of one part of the pattern or design disagreeing with another

page_text: part when once the rollers are properly set by means of the ordinary
box wheels.
For this purpose in one arrangement instead of driving the bowl from
the rollers I make the shaft of the bowl the driving shaft, and fix upon
it at each end a crown or toothed wheel into which is geared box toothed 5
wheels on the maundrils of the rollers, the circular pitch of each wheel
exactly corresponding with the periphery of its corresponding roller, it
being understood that the rollers are of the same or different diameters
according to the pattern or design.
In another arrangement I cause box toothed wheels on the maundril 1
or maundrils of one or more rollers to gear into the driving wheel giving
motion to the bowl and crown wheels before mentioned, and all the
printing rollers geared as before described.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Laycock in the Great Seal Patent Office
on the 25th November 1871.
