ALF THE SIZE OF THE COLUNIBIAN PRESS, DOUBLE ITS
SPEED, AND MORE THAN DOUBLE ITS POWER,

tl=iTH OXLI ONE MAN TO WORK IT!
KITCHEN'S PATENT SELF-INKING PRE-SS, pos-
sessing the above Requisites and Qualifications, may now
be seen at I% ork by *Master frinters, and other Gentlemen in-
terested in the Improvement of the Arts, at the Office of the
Newcastle %TOW nal.
Solid Forms are worked at the,self-Inking Press without an
Overlay.
The Presses will be constructed at the celebrated Works of
Messrs. R. and W. Hawthorn, Civil Engineers, Newcastle,
those Gentlemen having kindly afforded most valuable assist-
ance in what may be termed tne Architecture of the Machine,
including the calculations for the dimensions and proportions
of its several parts, and a symmetrical arrangement of the
whole upon unerring scientific and philosophical principles, so
that the Trade may rely upon the strength and truth of each
Press; whilst it is confidently asserted that in beauty of appear-
ance the Self-Inking Press is not excelled or even equalled, by
any hitherto known. Many Orders are now in course of exe-
cution, not only for Offices in England, Ireland, and Scotland,
but in the United States. Those of the Trade who have already
had an opportunity of judging, have expressed their delight and
astonishment at the beauty, effectiveness, and general utility of
this invention, it being alike applicable to every description of
Printing, and by its price placed within the reach of every res-
pectable Master.
The Self-Inking Press is peculiarly adapted for Book-work.
Correct register is obtained with less than-ordinary trouble.
Testimonials from experienced Master Printers and Over-
seers, who have seen the Machine at work, will be published
shortly.
EXTRACT FROM THE INVENTOR'S CIRCULAR.
Every experiment has been tried that practical experience
could suggest, with a view to ascertain the capabilities and
powers of the Press. The Machine already completed by the
Messrs. Hawthorn is calculated for a super-royal sheet and
the form generally used was a broadside of solid small type,_
The result of these several trials has more than answered the
most sanguine expectations, and fully proved that my calcula-
tions had been considerably underrated. In the foil ins de-
scription I have been equally careful to avoid exalt ration.
lne experiments were directed to ascertain— , The power
of the Press ; 2dly, Its speed; and, idly, Its eral applicabi-
y t to alt descripuous of work.

FIRST, AS TO POWER.
The power of the Self-Inking Press is, upon the most mode-
rate calculation, double that of the Columbian. It is certain
that, if the connecting-rod and cheek-pies were adjusted (which
can be dune readily and with case) so as to give the leverages
full play and the power of a strong man applied, the most
massive iron-frame ever made for a printing-Press would be
easily snapped asunder.

SECONDLY, AS TO spimo.
The result, as to speed, enables me to affirm, as a general
rule, that one man will, (with the improvements we contemplate
in the Machine s now in progress,) be enabled to accomplish
double the work that two men can now perform at the Colum-
bian; in other words, that one man wilt throw off as many im-
pressions as four men can ;LOW complete at two presses. Of course,
it would be difficult to lay down an exact rule as to the precise
number of impressions per hour, because much will depend
upon the activity and dexterity of the workman. I will take,
however, as a criterion, a man who is tolerably active at his
business, and suppose lie can pull at the common press, with a
companion to rots for him, 250 impiesSions per hour of a book
form—the same man would, at the Self-Inking Press, tv:thout
assistance, print vpwaras of 500 per hour. If a light form, he
would throw off 60U impressions per hour; and of a large news-
form, one man would certainly, with a fly-boy, print with ease
an impression of 1500 copies in three- hours.

I may as well remark that the Self-Inking Press will fall short
of the Napier Machine as to rapidity. but here the compari-
son ends. The Napier Machine requires three persons to at-
tend it: the Self-Inking Press only oue. The Napier Machine
is not applicable to a tithe of the work required to he performed
in a respectable office ; but it is perfectly immaterial whether a
heavy broadside or a light circular be lam on the Kitchen Press,
as a proof of which I may add, we are now working every thing
at it that comes to the Journal printing-tiflice. \Vith tue Na-
pier Machine so much time is rust in " making ready" for a
short number, that its speed whet' in operation dues nut compen-
sate for the delay; but at the Se,f-Inking Press, lornis of all
descriptions are gut to work much sootier titan with the Colum-
bian or any other known invention. The Napier Machine (and
every other where the cylinder is used) injures the types; but
the eif-liikiug Press is not imble to tins (injection. 'the Price
of the Napier ,Machine has hitherto been' i.:500; the largest Self-
Inking Press, is little more than °he-fourth of that sum, and
the smaller one only about one-lifth.
And, after ad, even as to speed, it is respectfully submittad
that ,500 impressions per bout is suitieleut fur uiiy provincid:
