Year: 1879

page_text: LETTERS PATENT to Thomas Hargreaves Taylor, of Manchester, in the County
of Lancaster, for the Invention of "IMPROVEMENTS IN MULTIPLE COPYING
APPARATUS, ALSO APPLICABLE TO COPYING PRESSES."
Sealed the 3rd February 1880, and dated the 4th August 1879.
PROVISIONAL SPECIFICATION left by the said Thomas Hargreaves Taylor
at the Office of the Commissioners of Patents on the 4th August 1879.
"
THOMAS HARGREAVES TAYLOR, of Manchester, in the County of Lancaster.
IMPROVEMENTS IN MULTIPLE COPYING APPARATUS, ALSO APPLICABLE TO COPYING
PRESSES."
These improvements relate especially to that class of multiple copying apparatus
which formed the subject of Letters Patent, No. 3159, granted to me on the 9th
day of August 1878, but are also applicable to other classes of multiple copying
apparatus, and in the construction of copying presses.
I use a case of wood or other suitable unyielding material, with a strong hinge
at the back connected to an iron or metal band arranged transversely from back to
front, both on or around the upper and lower parts. To the top band at the front
edge I attach a lever by a link or links allowing the lever to fall on the top, which
lever acts on a hooked fulcrum fixed to the lower part in front of the case in such
a manner as to draw down the upper part of the case, or plate, or lid as a press,
and retain its position when forced over the centre, whereby the two parts are
locked together, giving a sufficient pressure for copying.
As applied to copying presses, by rendering the hinges and fulcrum adjustable, I
arrange for various thicknesses of copying books to be used in the same press.

THOMAS HARGREAVES TAYLOR, of Manchester, in the County of Lancaster. "Iм-
PROVEMENTS IN MULTIPLE COPYING APPARATUS, ALSO APPLICABLE TO COPYING
PRESSES,"
These improvements refer especially to that class of multiple copying apparatus
which formed the subject of Letters Patent, No. 3159, granted to me on the 9th
day of August 1878, but are also applicable to other classes of multiple copying
apparatus, and in the construction of copying presses.
And in order that this my said Invention may be the more readily understood
and carried into practical effect I have hereunto annexed a Drawing illustrative of
my improvements, and will now proceed to describe the same, reference being had
to the Figures and letters of reference marked thereon.
Figure 1 is a plan, and Figure 3 a side view of a multiple copying apparatus or
copying press constructed in accordance with my Invention; and Figure 2 is a side
sectional view of Figure 1 across the line a-b.
In all the views A and A¹ form the upper and lower parts of a case of wood or
other unyielding material hinged together with a strong hinge B at the back, such
hinges forming part of an iron or other metal band C arranged to extend from back
to front of the case, and secured both on or around the upper and lower parts A
and A. To the top band at the front edge I connect a lever D by a link or links E so
as to allow the same to fall back on to the top of the apparatus, or to be drawn down so
as to act upon the hooked fulcrum F, which forms part of the lower or underneath
band and projects upwards in front, as illustrated. The action of this lever D upon
the hooked fulcrum F is to draw down the upper part of the case so that when the
short arm D' of the lever D is forced over the centre and hooked on the fulcrum F
the two parts A and A¹ become not only locked together and retained in such
position, but sufficient pressure is obtained for copying purposes, the copying book
G being placed between the two parts of the case, as illustrated.
In Figure 2 the lever is illustrated in the act of passing round the nose of the
toothed fulcrum F, and in Figure 3 the apparatus is shewn locked together in the
act of copying. I thus construct a multiple copying apparatus, suitable also as a
copying press. As applied to copying presses, by rendering the hinges and fulcrum
adjustable I arrange for various thicknesses of books to be used in the same
press.
Having thus particularly described and ascertained the nature of this my said
Invention, together with the best methods with which I am acquainted for carrying
the same into practical effect, I wish it to be understood that I claim,-
The construction and arrangement of multiple copying apparatus or copying
press, substantially as hereinbefore described and illustrated on the accompanying
Drawing.
In witness whereof, I, the said Thomas Hargreaves Taylor, have hereunto
set my hand and seal, this Third day of February, in the year of our Lord
THOS. HARGREAVES TAYLOR. (L.S.)
