PROVISIONAL SPECIFICATION left by the said Thomas Jones Smith at the
Office of the Commissioners of Patents, with his Petition, on the
14th January 1860.
I, THOMAS JONES SMITH, of Plaistow Marshes in the County of. Essex,
Engineer, do hereby declare the nature of the said Invention for "AN IMPROVED
MACHINE FOR PRINTING, IN MORE THAN ONE COLOR AT A TIME," to be as follows:-
This. Invention consists of certain machinery by the means of which printing
may be done in more than one color at a time in the following, manner :-
A metallic framing is erected of any suitable construction, the centre part
thereof being somewhat in the form of a V, at the lower part of this framing.
aro spur wheels working into each other on cranked shafts, one up and the,
other down alternately. On each side of the V frame is placed a case holding,
a form, each form being inked with the required color by means of inking
rollers, the sheet cylinder is placed between these form frames with a wheel.
affixed to its end, and has a number of teeth around one part of its periphery

page_text: corresponding in number with those on the end of the form frames so that
when the crank on the left hand with its guide rod has drawn down the frame
on the same side it has made the cylinder revolve about one third the circum-
ference having printed-one-color-when-the-crank-on-the-right hand.commences.
pushing upwards the other form frame which catches the first tooth of the
cylinder wheel, and also carries it round, thus printing another color, on the
same sheet, the crank rods and frames are connected to each other by suitable
chains passing over rollers or grooved wheels affixed thereto, and working in
slides on the framing of the machine upon this principle more than two colors
may be printed on the same cylinder.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Jones Smith in the Great Seal Patent Office on the
14th July 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
JONES SMITH, of Plaistow Marshes, in the County of Essex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of January, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-fourth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Thomas Jones Smith, Her special licence that I, the said Thomas
Jones Smith, my executors, administrators, and assigns, or such others as I, the
said Thomas.Jones Smith, my_executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "AN IMPROVED MACHINE
FOR PRINTING IN MORE THAN ONE COLOR AT A TIME," upon the condition
(amongst others) that I, the said Thomas Jones Smith, my executors or admi-
nistrators, by an instrument in writing under my, or their, or one of their
hands and seals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Thomas Jones Smith, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-

page_text: object is effected it will be necessary to refer to the accompanying Sheets of
Drawings and to the figures and letters of reference marked thereon as
follows.
DESCRIPTION OF THE DRAWINGS.
At Sheet 1, Fig. 1 is a side elevation of the machine as it would appear
when in use; at Sheet 2, Fig. 2 is a partial view of a portion of the inner
working parts; Fig. 3, side view of chain motion detached; Figs. 4, 5,
and 6, various views of travelling form table; similar letters of reference denote
corresponding parts. A, A, is the metallic framing of the machine on the
lower part of which is a placed the main driving shaft c, and on the upper part
of the cylinder d on the end of the cylinder d is a wheel having teeth on one part
of its periphery only, these teeth take into others on the end of the form case e,
which travels on an inner framing b; thus it will be seen that as the type or form
case is brought drown by the cranks, rods, and chains shewn at Fig. 3, it causes
the cylinder d, to revolve, printing the paper on the cylinder in one color; on the
last tooth of the cylinder wheel leaving the form case it is drawn up to its former
position by means of a connecting rod f*, and counter balance weight f, by which
time the teeth on the cylinder wheel have been caught by the teeth on another
form case g,
which is run up on the inclined frame b, by means of the rod h, being
driven by a crank actuated by the arrangement of toothed wheels shewn
Fig. 1, thus printing a form of another color between or among that already
printed. At Fig. 1 also will be seen the paper pile table i, and the laying on
board j. At Figs. 4 and 5, Sheet 2, will be seen two views of the travelling
form case, and frame on which it moves, Fig. 6 being a longitudinal and
vertical section of Fig. 4, shewing that by an inclined plane k, and fixed
screw 7, the type are to be raised or lowered as may be required. The
arrangement of inking rollers shewn together with the various motions at Fig. 2
will be readily understood to those experienced in the art.
Having now described the nature and object of my said Invention of "An Im-
proved Machine for Printing in more than One Color at a Time," together with
the manner in which the same is to be performed, I would remark, in conclusion,
that I do not confine or restrict myself to the precise details herein described
and shewn in the accompanying Sheets of illustrative Drawings, as many slight

page_text: modifications and variations may be made therein without in any way departing
from the principle of my Invention, for instance only two forms are shewn for
printing but two colors, but more may be used on the same principle, but what
I claim as my Invention intended to be secured-to-me by the herein in part
recited Letters Patent is printing in more than one color at a time in the
manner and by the means shewn and herein-before described and set forth.
In witness whereof, I, the said Thomas Jones Smith have hereunto set my
hand and seal, this Thirteenth day of July, in the year of our Lord
One thousand eight hundred and sixty..
