Year: 1879

page_text: LETTERS PATENT to Joseph Julius Sachs, of Barrow in Furness, in the County
of Lancaster, for the Invention of "IMPROVEMENTS IN PRINTING PATTERNS OR
DESIGNS UPON TEXTILE AND OTHER FABRICS OR MATERIALS."
Sealed the 15th August 1879, and dated the 25th March 1879.
PROVISIONAL SPECIFICATION left by the said Joseph Julius Sachs at the
Office of the Commissioners of Patents on the 25th March 1879.
JOSEPH JULIUS SACHS, of Barrow in Furness, in the County of Lancaster. "IM-
PROVEMENTS IN PRINTING PATTERNS OR DESIGNS UPON TEXTILE AND OTHER FABRICS
OR MATERIALS."
My Invention relates to the printing of cotton and woollen cloths and tissues
and of other textile fabrics, and of paper and other fabrics or materials and surfaces.
In lieu of the ordinary rollers or blocks used for printing I employ a printing
surface or medium consisting of a textile material or fabric which is woven, knitted,
crocheted, embroidered, or otherwise prepared or an impression obtained therefrom
by electrotype or other suitable process. I suitably charge, or supply, or coat this
material or the printing surface thereof with the color or matter, and transfer such
color or matter to the material, or substance, or surface to be printed by means of
roller pressure or of the pressure of a platten, or of pressure applied in any suitable
manner. The fabric, material, or surface to be printed may be brought into contact
with the printing surface in any manner which will produce the desired effect. By
way of example, I will indicate one method of carrying my Invention into effect.
I take a piece of textile material woven or produced with a suitable pattern, and fix
it on the surface of a roller. The said roller is then mounted in a printing machine,
and is treated with the printing matter, and the fabric to be printed is fed through
the machine as when printing in the ordinary way. In some cases the printing
material may be in the form of an endless belt or of a web, and in others it would
be applied to other than roller surfaces. By the means indicated a great variety of
effects can be obtained, and when desirable several pieces may be printed simul-
taneously by being superimposed, or may be printed on both sides at the same
time. In some cases the rollers, plattens, or beds may be elastic to some extent.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Joseph Julius Sachs in the Great Seal Patent Office on the 16th
September 1879.
JOSEPH JULIUS SACHS, of Barrow in Furness, in the County of Lancaster. "IM-
PROVEMENTS IN PRINTING."
My said Invention relates to the use for printing patterns or designs upon textile
and other fabrics or materials, of printing surfaces or media consisting of open or
figured woven, knitted, embroidered, crotchetted, or other fabrics.
According to one part of my said Invention I employ as the printing surface or
medium a close figured fabric the pattern on which is by the process of printing
reproduced upon the textile or other fabric or material to be printed. In carrying
out this part of my said Invention I first, by preference, prepare such figured fabric
in order to impart the requisite rigidity thereto, and render it not liable to be
affected by the color or other matter to be subsequently applied to it; and I then
place the fabric either around a roller, or cylinder, or on a printing block, or I form
the fabric into an endless web, and mount the same upon rollers or arrange it in a
single length so as to be capable of longitudinal motion.
When a roller or cylinder is employed it is mounted in bearings in a suitable
frame so as to be capable of turning therein, and means are provided for imparting
rotatory motion to the said roller or cylinder, also for supplying color or other
printing matter thereto, and for carrying and feeding along the fabric or material to
be printed in contact with the roller or cylinder, and subjecting it to the requisite
pressure. The fabric or material to be printed having then been introduced into
the machine, and the latter set in motion, color or other matter is supplied- to the
surface of the printing roller or cylinder, and the fabric or material is passed through
the machine in contact with the printing roller or cylinder, which is caused to
exercise the requisite pressure upon it, the pattern of the printing roller or cylinder
is thus reproduced upon the fabric or material as when ordinary printing surfaces
or media are employed. When an endless web is used the operation of printing is
effected in a like manner. Similarly the printing fabric arranged in a sheet or
length and the fabric or material to be printed may be conducted together between
pressure rollers, or they may be extended upon a flat surface and subjected to
pressure between a roller and a platten; or the operation of printing may be pro-
ceeded with after the manner of using ordinary printing blocks.
The parts upon which the printing fabric or material is mounted or through
which pressure is applied or received may be covered with felt, caoutchouc, or other
suitable elastic material.
In the case of lace or other open worked fabrics or materials used as printing
media, when it is required to print a number of copies of the counterpart of the
pattern or design I perform the operation simultaneously upon a number of pieces
of the textile or other fabric or material to be printed in the following manner,
videlicet:-The several pieces of fabric or material are secured together by their
edges in clamps or frames with the open worked printed surface or pattern either
above or below, or both above and below the same, and the color or other matter is
forced through the whole either by the ordinary atmospheric pressure by producing
a vacuum on the opposite side to that at which the reservoir of color or other matter is
situate, or by means of a blast of air, or by suction, as will be well understood. The
figure of the interstices of the pattern will thus be reproduced simultaneously upon
the whole pile of fabrics, leaving the figure of the full parts of the pattern in blank
upon such fabrics. By this arrangement also both sides of each fabric are printed
at the same time, and a similar method may be adopted when it is required to print
single fabrics on both sides with the same pattern.
According to another part of my said Invention which is applicable when both
open worked and close figured fabrics are used in lieu of employing such fabrics for

page_text: printing direct upon the fabrics or materials to be printed I take casts, copies, or
impressions from the said printing fabrics by the electro type or other suitable
process, and use such casts, copies, or impressions as the printing surfaces or media,
or for other purposes. When it is required to obtain roller or cylindrical surfaces
this part of my said Invention may be conveniently carried out in the following
manner, videlicet:-The fabric is placed around a roller or cylinder, and a hollow
cast of gypsum or india-rubber is taken from the same, the said cast bearing upon
its interior the impression of the roller fabric; from the interior of this gypsum or
india rubber cast may then be taken a cast by the electro type process, which will
thus bear on its exterior a facsimile of the pattern on the original roller, and may
be used as the printing cylinder or otherwise.
Having now described and particularly ascertained the nature of my said Inven-
tion, and the manner in which the same is or may be used or carried into effect, I
would observe in conclusion that what I consider to be novel and original, and
therefore claim as the Invention secured to me by the hereinbefore in part recited
Letters Patent is,―
First. The employment of close figured fabrics as printing surfaces or media,
substantially as herein before described.
Secondly. The employment as printing surfaces or media of casts, copies, or
impressions obtained from open worked or close figured fabrics, substantially as
herein before described.
Thirdly. The system or mode of printing simultaneously multiple copies of the
interspaces of an open worked pattern, substantially as herein before described.
Fourthly. The system or mode of reproducing the counterpart of an open worked
pattern upon both sides of a fabric or material simultaneously, substantially as
hereinbefore described.
In witness whereof, I, the said Joseph Julius Sachs, have to this my
Specification set my hand and seal, this Twenty-eighth day of August, One
thousand eight hundred and seventy nine.
