Year: 1879

page_text: LETTERS PATENT to Frederick Walton, of Heatham House, Twickenham, in
the County of Middlesex, for the Invention of "IMPROVEMENTS IN BOOK
AND PORTFOLIO COVERS, AND IN THE PROCESS FOR MANUFACTURING THE
SAME.
,,
Sealed the 5th September 1879, and dated the 22nd March 1879.
PROVISIONAL SPECIFICATION left by the said Frederick Walton at the
Office of the Commissioners of Patents on the 22nd March 1879.
FREDERICK WALTON, of Heatham House, Twickenham, in the County of
Middlesex. ." IMPROVEMENTS IN BOOK AND PORTFOLIO COVERS, AND IN THE
PROCESS FOR MANUFACTURING THE SAME."
This Invention has for its object improvements in the manufacture of book and
portfolio covers.
The usual method of manufacturing book covers is to take two stout card boards,
one forming the back and the other the front cover; these are faced with leather or
cloth, sized and embossed with some pattern thereon, usually an imitation of leather..
They are then subjected to the action of an arming press having a die fixed therein,
whereby a suitable design is impressed on the cover. The effects so produced are
comparatively flat, and also the surfaces are easily damaged by wet or moisture,,
the same not being waterproof.
My improvement consists in the manufacture of book covers by means of
embossing rollers in continuous lengths and in the application of solidified oils.
combined with colour and fibre for that purpose, whereby I obtain the effect' of the
most expensive stamped morocco leather covers with more sharpness and clearness
of outline, with the advantage of the covers being washable without fear of,
injury.
To effect this I use a machine having three rollers geared together and working
as is indicated by Figure 1 of the annexed Drawing..

page_text: A and B spread a coat of the composition on a fabric which passes to the engraved
roller C, which impresses with great sharpness of outline the desired pattern for
the two covers and connecting piece, as illustrated by Figure 2. The covers are so
produced in a continuous sheet.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Frederick Walton in the Great Seal Patent Office on the 22nd

This Invention has for its object improvements in book and portfolio covers, and
in the process for manufacturing the same.
The usual method of manufacturing book covers is to take two stout card boards,
one forming the back and the other the front cover; these are faced with leather or
cloth, sized and embossed with some pattern thereon, usually an imitation of leather.
They are then subjected to the action of an arming press having a die fixed therein,
whereby a suitable design is impressed on the cover. The effects so produced are
comparatively flat, and also the surfaces are easily damaged by wet or moisture, the
same not being waterproof.
My improvement consists in the manufacture of book covers by means of
embossing rollers in continuous lengths, and in the application of solidified oils
combined with colour and fibre for that purpose, whereby I obtain the effect of the
most expensive stamped morocco leather covers, with more sharpness and clearness
of outline, with the advantage of the covers being washable without fear of
injury.
To effect this I use a machine having three rollers geared together and working
as is indicated by Figure 1 of the annexed Drawings. A and B. spread a coat of
the composition on a fabric. The coated fabric passes to the engraved roller C,
which impresses with great sharpness of outline the desired pattern for the two,
covers D, E, and connecting piece F, as illustrated by Figure 2. The covers, with
their connecting pieces, are so produced in a continuous sheet.
The sheet so formed may afterwards be cut up into lengths, each containing a
back and front cover connected by a connecting piece, and the covers may be
stiffened by card board pasted on to them at the back.
Covers formed in the above manner can also be used as panels without the con-
necting pieces, leather in this case being used to form the backs and to connect the
two covers together.
A suitable composition and that which I prefer to employ, consists of the following

prepared for the manufacture of floor cloth. The ingredients are :—
100 lbs. oxidised oil.

I claim,-
First. The application of the solidified oils in combination with fibrous and
coloring matter to the manufacture of book and portfolio covers.
Second. The forming book and portfolio covers from compounds of solidified oils
by rolling them in continuous sheets, substantially as herein described.
In witness whereof, I, the said Frederick Walton, have hereunto set my
hand and seal, this Twentieth day of September, in the year of our
Lord One thousand eight hundred and seventy nine.
