AN IMPROVED APPARATUS FOR LOCKING UP FORMES IN CHASES
Year: 1878

page_text: LETTERS PATENT to Carlo Giuseppe Squintani, of Ludgate Circus Buildings,
in the City of London, Merchant and Manufacturer, for the Invention of
"
AN IMPROVED APPARATUS FOR LOCKING UP FORMES IN CHASES."
Sealed the 24th January 1879, and dated the 2nd November 1878.
PROVISIONAL SPECIFICATION left by the said Carlo Giuseppe Squintani at
the Office of the Commissioners of Patents on the 2nd November 1878.
CARLO GIUSEPPE SQUINTANI, of Ludgate Circus Buildings, in the City of
London, Merchant and Manufacturer. "AN IMPROVED APPARATUS FOR LOCKING
UP FORMES' IN CHASES."
"
This Invention consists in the construction of an improved apparatus for locking
up "formes of type, blocks, or electrotypes in chases for printing, whereby the
locking up is effected in a much more simple, speedy, and effective manner than
hitherto.
The improved apparatus is constructed of a foot or side "stick" consisting of a
metal bar, square on one side for fitting and bearing against the side or foot of the
"forme;
the opposite side of this bar is inclined from each end towards the
centre.
"
I provide two "quoins" with angles corresponding with the inclines or slopes of
the bar, the said "quoins" being connected together by means of a right and left
handed screw (which passes through the quoins), such screw being provided with a
nut, wheel, or boss suitably placed for turning the screw.
In some cases it may be desirable to connect the screw to the bar by any suitable
arrangement to ensure the "quoins” being kept at equal distances from the centre.
By this construction it will be understood that if the hereinbefore described

page_text: screw be turned, the said "quoins" will be moved towards or away from one
another (according to the direction in which the screw is turned), and that conse-
quently when the "quoins" are moved-towards_the_centre the "stick"
or bar will
be pressed against the side or foot of the "forme" through the whole-of-its-length,
and thus press the "forme in an even and-effective manner; whereas if the screw
be turned in the opposite direction the "quoins" will be moved from the centre and
the "forme" will be released from the pressure of the "stick"
or bar.
The herein before described driving screw may be turned by means of a knob or
button operating a worm wheel gearing into a thread or endless screw on the centre
of the driving screw.

the said Carlo Giuseppe Squintani in the Great Seal Patent Office on the 2nd
May 1879.
CARLO GIUSEPPE SQUINTANI, of Ludgate Circus Buildings, in the City of
London, Merchant and Manufacturer. "AN IMPROVED APPARATUS FOR LOCKING
UP FORMES' IN CHASES."
This Invention consists in the construction of an improved apparatus for locking.
up "formes" of type, blocks, or electrotypes in chases for printing, whereby the
locking up is effected in a much more simple, speedy, and effective manner than
hitherto.
The improved apparatus is constructed of a foot or side "stick" consisting of a
metal bar, square on one side for fitting and bearing against the side or foot of the
forme;" the opposite side of this bar is inclined from each end towards the
centre.
"
I provide two "quoins" with angles corresponding with the inclines or slopes of
the bar, the said "quoins" being connected together by means of a right and left
handed screw (which passes through the "quoins"), such screw being provided
with a nut, wheel, or boss suitably placed for turning the screw.
But to make my Invention better understood I will proceed to describe the same
by reference to the accompanying Drawing, in which Figure 1 is a plan and
Figure 2 an end view of my improved apparatus for locking up "formes" in
chases; Figure 3, section of the same on line A, B, of Figure 1; Figure 4 is a plan
on a smaller scale of a chase shewing the "forme "locked up therein by means of
my improved apparatus; Figures 5 and 6, plan and end view, and Figure 7, a
section on line C, D, of Figure 5, of a modified construction of apparatus. Similar
letters in all the Figures represent similar parts.
"
<
In the apparatus shewn in Figures 1, 2, 3, and 4, A is the foot or side stick,
which consists of a metal bar, square on one side a, a, for fitting and bearing against
the side or foot of the "forme "c, c; the opposite side b, b, of the foot or side
'stick "A is inclined, as shewn, from each end towards the centre; d, d, are the
two "quoins," the inclined surfaces of which correspond with the inclined surfaces
of the "stick" A; e, e, is the right and left handed screw passing through the
'quoins" d, d, which are cut with female threads corresponding with the right and
left handed screw threads respectively. The inclined sides b, b, of the "stick" A are
cut with a dovetail groove f, as shewn in Figure 3 (and in dotted lines at Figure 1),
in which slide the tongues or dovetails on the quoins d, by which means the
whole of the parts of the apparatus are kept together and the "quoins" prevented
from turning on the screw; his the nut, wheel, or boss by which the screw is
turned by means of a suitable key.
"
By this construction of apparatus it will be understood that if the herein before
described screw e be turned the said "quoins" d, d, will be moved towards or away
from one another (according to the direction in which the screw is turned), and
that consequently when the "quoins" d, d, are moved towards the centre the
27
stick or bar A will be pressed against the side or foot of the "forme "c through
the whole of its length, and thus press the "forme" c in an even and effective
manner, whereas if the screw e be turned in the opposite direction the quoins d, d,
will be moved from the centre and the "forme" c will be released from the pressure
of the "stick or bar A.
"
In the modified construction of apparatus shewn in Figures 5, 6, and 7, instead
of forming the "quoins" d, d, with a dovetail tongue, and the stick A with a
corresponding dovetail groove, as hercinbefore described, the " quoins" d, d, and
"stick" A are formed with plain tongues i, i, and a plain groovej respectively; and I
provide a supplementary stick or bar B in the return ends kc, c¹, of which the
screw e turus freely; this bar B is grooved, a tongue on each of the "quoins "d

page_text: sliding in the said groove. The object of this arrangement is to prevent the
quoins d, d, from turning-on-the-screw-e-and-thus-keeping-them_always_cqui-
distant from the centre of the "stick."
Having thus described my said Invention, and the best means with which I am
acquainted for carrying the same into effect, I wish it to be understood that I do
not confine myself to the precise details herein laid down and shewn in the
Drawing, as the same may be varied without departing from the principle of my
Invention; but what I do claim is,-
_Firstly. The construction and employment of improved apparatus for locking up
"formes" in chases, arranged and operating substantially as hercinbefore described,
and represented in the accompanying Drawing, or any mere modification thereof.
Secondly. The combination with an inclined "stick" A of the "quoins" d, d,
operated by a right and left handed screw, as hereinbefore described, and repre-
sented in the accompanying Drawing.
In witness whereof, I, the said Carlo Giuseppe Squintani, have hereto set my
hand and seal, this Second day of May, in the year of our Lord One
thousand eight hundred and seventy nine.
C. G. SQUINTANI. .(L.S.)
