Year: 1861

page_text: LETTERS PATENT to Corneille Wynants, of Saint Josse ten Noode, in
the Kingdom of Belgium, Engine Builder, for the Invention of." AN
IMPROVED CHASE FOR PRINTING PRESSES."
Sealed the 11th April 1862, and dated the 15th October 1861.
PROVISIONAL SPECIFICATION left by the said Corneille Wynants at the
Office of the Commissioners of Patents, with his Petition, on the 15th
October 1861.
I, CORNEILLE WYNANTS, of Saint Josse ten Noode, in the Kingdom of
Belgium, Engine Builder, do hereby declare the nature of the said Invention
for "AN IMPROVED CHASE FOR PRINTING PRESSES," to be as follows:-
My Invention consists in so constructing chases used in printing that the
pages of type placed therein may be tightened and firmly secured in position by
means of eccentrics, or volutes, or scrolls, governed by a key or other suitable
means to cause them to press against the setting rules and by them upon the
pages of type to secure them tightly in the chase; and on turning the eccentrics,
volutes, or scrolls in an opposite direction the type is immediately released
from pressure, and may be removed or changed with ease. By this means I
avoid the necessity of binding the pages of type with string; I also prevent the
type from slipping or falling into pie, and obtain a considerable saving of
time.

page_text: To the sides of a rectangular frame, which I prefer to be of wrought iron,
I connect the setting rules by means of screws which pass freely through the
sides of the frame so as to have a certain play therein, and at their ends are
screwed into the setting rules, which by this means have sufficient play to
allow of their being pressed against or drawn back from the pages of type
contained in the frame. In suitable apertures formed in the sides of the chase
I place the eccentrics, or volutes, or scrolls to act upon the setting rules.
Eccentrics may also be used to secure the chase, when required, between
flanges on the marble of the press.
In order to the better tightening of the type in the chase, I cover with any
suitable elastic material both sides of the setting rules and the sides of the
chase against which they press.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Corneille Wynants in the Great Seal Patent Office on the
12th April 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CORNEILLE
WYNANTS, of St. Josse ten Noode, in the Kingdom of Belgium, Engine
Builder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of October, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Corneille Wynants, Her special licence that I, the said Corneille
Wynants, my executors, administrators, and assigns; or such others as I, the
said Corneille Wynants, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "AN IMPROVED CHASE FOR PRINTING PRESSES," upon the condition (amongst
others) that I, the said Corneille Wynants, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and cause
the same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.

page_text: NOW KNOW YE, that I, the said Corneille Wynants, do hereby declare
the nature of the said Invention, and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say:-
My Invention consists in so constructing chases used in printing that the
pages of type placed therein may be tightened and firmly secured in position
by means of eccentrics, or volutes, or scrolls governed by a key or other
suitable means to cause them to press against the setting rules, and by them
upon the pages of type to secure them tightly in the chase; and on turning
the eccentrics, volutes, or scrolls in an opposite direction the type is imme-
diately released from pressure, and may be removed or changed with ease.
By this means I avoid the necessity of binding the pages of type with string;
I also prevent the type from slipping or falling into "pie," and obtain a con-
siderable saving of time.
To the sides of a rectangular frame, which I prefer to be of wrought iron,
I connect the setting rules by means of screws, which pass freely through the
sides of the frame so as to have a certain play therein, and at their ends they
are screwed into the setting rules, which by this means have sufficient play
to allow of their being pressed against or drawn back from the pages of type
contained in the frame. In suitable apertures formed in the sides of the chase
I place the eccentrics, or volutes, or scrolls which act upon the setting rules.
Eccentrics may also be used to secure the chase, when required, between
flanges on the marble of the press.
In order to the better tightening of the type in the chase, I cover with any
suitable elastic material both sides of the setting..rules and the sides of the
chase against which they press.
In order, however, that my Invention may be fully understood, I will
proceed to describe it more particularly by the aid of the accompanying
Drawings.
DESCRIPTION OF THE DRAWINGS.
Figure I. is a plan and Figure II. an end elevation of a chase constructed
according to my improvements. A, A, A¹, A', represents a wrought-iron
chase; B, B, are the setting rules which are connected to the sides A¹, A¹, of
the chase by the guide screws C, C, C, C, which pass freely through the sides
of the chase, and are at their ends screwed into the set rules B, and guide
them in their movements. In recesses or apertures formed in the sides A', A',
of the chase are placed the eccentrics D, D, D, D, which are fixed to`and

page_text: turn upon the pivots d, d, d, d, formed at their upper ends to fit a hollow key
by which they are made to revolve, and at their lower ends they are slightly
beaten down to secure them to the chase. The pages of type are placed in
the chase at T, T, T, T; and it will be readily understood that when the
eccentrics D, D, D, D, are caused to turn to the right they will make the set
rules B, B, advance and press against the pages of type so as to fix and hold
them tightly in position. By turning the eccentrics in a contrary direction
the pages s of type will be instantly released from pressure, and may be removed
readily from the chase.
Figure III. is an elevation of one of the pivots d, d, d, d, the upper end of
which in this case is hollowed to receive the solid end e of a key, Figure IV.
Figures V. and VI. represent in plan and in elevation part of the side A'
of the chase, and setting rule B, and show the pivot d of the eccentric D held
in position by a washer fattached to its lower end. The side of the set rule B
is covered with india-rubber at g.
Other modes of carrying my Invention into effect are represented in plan at
Figure VII. A, A, A, A, is a rectangular chase; T, T, T, T, are the pages
of type; B is a set rule.
Instead of attaching the eccentrics D to the sides of the chase, as herein-
before described in respect of Figures I. and II., I affix the said eccentrics in
a similar manner to blocks E, E, which I place between the set rules B and
the side A of the chase.
Figures VIII. and IX. are a longitudinal and side elevation of one of these
blocks E, and show the eccentric D working upon its pivot d. It will be
readily understood that the action of the eccentrics D attached to the blocks E
is exactly similar to that of the eccentrics D, Figures I. and II., herein-before
described.
Another mode of effecting the same object is shown at F, Figure VII.,
which is a set rule placed between the pages of type and the side of the
chase, and having affixed to it eccentrics D', D', D', D', which, when they are
made to revolve, press against the side of the chase, and cause the opposite side
of the set rule to fasten or release the pages of type, as may be required.
J represents part of a flange or rim round the marble of the press; the chase
is secured thereto either by a set rule F¹ provided with eccentrics similar to
that shown at F, or by any number of eccentric blocks E' similar to the
blocks E, E, herein-before described, within the chase.
Having now described the nature of my improvements, and the means I
prefer to adopt in carrying the same into effect, I wish it to be understood

page_text: that I do not confine myself to the precise details herein-before described, and
illustrated in the accompanying Drawings, as the same may be varied without
departing from the nature of my Invention; but what I claim is,-
First, the mode of constructing chases used in printing so that the pages of
type placed therein may be tightened and secured in position or released from
pressure, as required, by means of eccentrics, or volutes, or scrolls acting upon
set rules, in substance as described.
Second, the mode of securing the chase to the marble of the table or press,
when required, by means of eccentrics, volutes, or scrolls, in substance as
described.
Third, the use of india-rubber or other suitable elastic material, when
required, to cover the sides of the set rules and chase, so as to produce a
more effectual tightening thereof, as described.
In witness whereof, I, the said Corneille Wynants, have hereunto set
my hand and seal, this Eighth day of April, in the year of our Lord
One thousand eight hundred and sixty-two.
CORNEILLE WYNANTS. (L.S.)
