[Communicated from abroad by FREDERIC HENRY LIEKER, of the City of Toronto, in
the County of York, in the Province of Ontario, Canada, Manufacturer.]
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E. do hereby declare the nature of this invention and in what manner the same
is to be performed, to be particularly described and ascertained in and by the following
statement:-
The object of the invention is to cheapen the cost of manufacturing covers and to
produce at the same time a superior article; and it consists essentially, in first pasting
the paper or other stiffening material upon the face of the leather, then cutting the
edges to the proper shape then binding the edges so shaped with a narrow strip of
very thin leather or other suitable material, then placing the cover so prepared in an
embossing press by which the embossing is effected after which the crease is formed
by a tool placed in an embossing press substantially as hereinafter more particularly
explained.
-
Figures 1, 2, 3, 4, 5, and 6 illustrate the process now adopted in manufacturing
covers similar to the kind for which this improved process is designed.
Figures 7, 8, 9, and 10 illustrate this improved process.
In order to explain the advantages of this process it will be necessary to refer first
to the process now commonly adopted for producing the class of covers now made by
this improved process. In the old process a piece of leather or material representing
the same is first cut into shape its edges pared and then embossed on one of its sides
as shown in Figure 1. The opposite side of Figure 1 is shown in Figure 2 which also
represents the cover cut into proper shape and its edges a pared or chamfered off in
order that the said edges may be thin enough to turn over and cover the edge of the
paper or other stiffening material b which is pasted on it as indicated in Figure 3 and
in Figure 4 the pared or chamfered edges are represented as turned over the edges of
the paper b; the dotted lines in Figure 3 representing the inside edge of the chamfer
while the dotted lines in. Figure 4 represent the outside edge of the paper or

page_text: stiffening b. The leather c is then pasted on as represented in Figure 5. During
this process the embossing which is done first is all worn away in places as shown
in Figure 6 so that the outside of the cover has not as finished an appearance as it has
in Figure 1. The creasing line d is made around the book near its edges as shown in
Figure 6 but owing to the wearing off of the embossing during the process just
described the said line runs through many bare places so that the outside appearance
of the cover is seriously affected.
In this improved process the leather or similar material is first cut to the shape
shown in Figure 7. It is then pasted upon the paper or other stiffening material b
the edge of which is shown turned up in Figure 7. After this the edges are trimmed
to the required shape and a narrow strip e of thin leather or other suitable material is
taken and pasted around the edge as indicated by Figure 8. When this is
accomplished the cover is placed in an embossing press and by subjecting it to
the requisite pressure it is embossed as shown in Figure 10 or in any other suitable
design. After thus embossing it, it is placed under a tool formed like a blunt cutter
corresponding in shape to the creasing line d which is formed on the cover by one
action of the press. A piece of leather c is then pasted over the paper 6 which is on
the opposite side of the cover to that which is embossed. By this process a cover is
finished in a very much shorter time than in the old process, and as the embossing is
not done until after the cover is otherwise completed the cover produced by this
process will have a handsome and finished appearance.
Having now particularly described and ascertained the nature of the said invention
as communicated to me by my foreign correspondent and in what manner the same is
to be performed I declare that what I claim is :-
1. An improved process for the manufacture of covers which consists in first pasting
the paper or other stiffening material upon the face of the leather then cutting the
edges to the proper shape then binding the edges so shaped with a narrow strip of
thin leather or other material and then placing the cover so prepared in an embossing
press substantially as and for the purpose specified.
