project was abandoned。



In 1816; Mr。 Cowper obtained a patent (No。3974) entitled;〃 A

Method of Printing Paper for Paper Hangings; and Other Purposes。〃



The principal feature of this invention consisted in the curving

or bending of stereotype plates for the purpose of being printed

in that form。  A number of machines for printing in two colours;

in exact register; was made for the Bank of England; and four

millions of One Pound notes were printed before the Bank

Directors determined to abolish their further issue。  The regular

mode of producing stereotype plates; from plaster of Paris

moulds; took so much time; that they could not then be used for

newspaper printing。



Two years later; in 1818; Mr。 Cowper invented and patented (No。 

4194) his great improvements in printing。  It may be mentioned

that he was then himself a printer; in partnership with Mr。

Applegath; his brother…in…law。  His invention consisted in the

perfect distribution of the ink; by giving end motion to the

rollers; so as to get a distribution crossways; as well as

lengthways。  This principle is at the very foundation of good

printing; and has been adopted in every machine since made。  The

very first experiment proved that the principle was right。  Mr。

Cowper was asked by Mr。 Walter to alter Koenig's machine at The

Times office; so as to obtain good distribution。  He adopted two

of Nicholson's single cylinders and flat formes of type。  Two

〃drums〃 were placed betwixt the cylinders to ensure accuracy in

the register;over and under which the sheet was conveyed in it

s progress from one cylinder to the other;the sheet being at

all times firmly held between two tapes; which bound it to the

cylinders and drums。  This is commonly called; in the trade; a

〃perfecting machine;〃 that is; it printed the paper on both sides

simultaneously; and is still much used for 〃book…work;〃 whilst

single cylinder machines are often used for provincial

newspapers。



After this; Mr。 Cowper designed the four cylinder machine for The

Times;by means of which from 4000 to 5000 sheets could be

printed from one forme in the hour。  In 1823; Mr。 Applegath

invented an improvement in the inking apparatus; by placing the

distributing rollers at an angle across the distributing table;

instead of forcing them endways by other means。



Mr。 Walter continued to devote the same unremitting attention to

his business as before。  He looked into all the details; was

familiar with every department; and; on an emergency; was willing

to lend a hand in any work requiring more than ordinary despatch。



Thus; it is related of him that; in the spring of 1833; shortly

after his return to Parliament as Member for Berkshire; he was at

The Times office one day; when an express arrived from Paris;

bringing the speech of the King of the French on the opening of

the Chambers。  The express arrived at 10 A。M。; after the day's

impression of the paper had been published; and the editors and

compositors had left the office。  It was important that the

speech should be published at once; and Mr。 Walter immediately

set to work upon it。  He first translated the document; then;

assisted by one compositor; he took his place at the type…case;

and set it up。  To the amazement of one of the staff; who dropped

in about noon; he 〃found Mr。 Walter; M。P。 for Berks; working in

his shirt…sleeves!〃  The speech was set and printed; and the

second edition was in the City by one o'clock。  Had he not

〃turned to〃 as he did; the whole expense of the express service

would have been lost。  And it is probable that there was not

another man in the whole establishment who could have performed

the double workintellectual and physicalwhich he that day

executed with his own head and hands。



Such an incident curiously illustrates his eminent success in

life。  It was simply the result of persevering diligence; which

shrank from no effort and neglected no detail; as well as of

prudence allied to boldness; but certainly not 〃of chance;〃 and;

above all; of highminded integrity and unimpeachable honesty。  It

is perhaps unnecessary to add more as to the merits of Mr。 Walter

as a man of enterprise in business; or as a public man and a

Member of Parliament。  The great work of his life was the

development of his journal; the history of which forms the best

monument to his merits and his powers。



The progressive improvement of steam printing machinery was not

affected by Mr。 Walter's death; which occurred in 1847。  He had

given it an impulse which it never lost。  In 1846 Mr。 Applegath

patented certain important improvements in the steam press。  The

general disposition of his new machine was that of a vertical

cylinder 200 inches in circumference; holding on it the type and

distributing surfaces; and surrounded alternately by inking

rollers and pressing cylinders。  Mr。 Applegath estimated in his

specification that in his new vertical system the machine; with

eight cylinders; would print about 10;000 sheets per hour。  The

new printing press came into use in 1848; and completely

justified the anticipations of its projector。



Applegath's machine; though successfully employed at The Times

office; did not come into general use。  It was; to a large

extent; superseded by the invention of Richard M。 Hoe; of New

York。  Hoe's process consisted in placing the types upon a

horizontal cylinder; against which the sheets were pressed by

exterior and smaller cylinders。  The types were arranged in

segments of a circle; each segment forming a frame that could be

fixed on the cylinder。  These printing machines were made with

from two to ten subsidiary cylinders。  The first presses sent by

Messrs。 Hoe & Co。 to this country were for Lloyd's Weekly

Newspaper; and were of the six…cylinder size。  These were

followed by two ten…cylinder machines; ordered by the present Mr。

Walter; for The Times。  Other English newspaper proprietorsboth

in London and the provinceswere supplied with the machines; as

many as thirty…five having been imported from America between

1856 and 1862。  It may be mentioned that the two ten…cylinder

Hoes made for The Times were driven at the rate of thirty…two

revolutions per minute; which gives a printing rate of 19;200 per

hour; or about 16;000 including stoppages。



Much of the ingenuity exercised both in the Applegath and Hoe

Machines was directed to the 〃chase;〃 which had to hold securely

upon its curved face the mass of movable type required to form a

page。  And now the enterprise of the proprietor of The Times

again came to the front。  The change effected in the art of

newspaper…printing; by the process of stereotypes; is scarcely

inferior to that by which the late Mr。 Walter applied steam…power

to the printing press; and certainly equal to that by which the

rotary press superseded the reciprocatory action of the flat

machine。



Stereotyping has a curious history。  Many attempts were made to

obtain solid
