Improvements in or connected with Machines or Apparatus for
Composing Type for Printing Purposes.
I HUGH HAMILTON Managing Director of The Type Setting Syndicate Limited of
2 Copthall Buildings in the City of London do hereby declare the nature of this.
invention which has been communicated to me from abroad by The Thorne Machine
Company of 32 Vesey Street New York in the United States of America to be as
follows:-
This Invention relates to improvements in the type setting and distribution machines
of the kind described in the Specifications of Letters Patent Nos. 3924 of 1880,
14517 and 15418 of 1887 and 3918 of 1888 and of the application for Letters Patent .
No. 12617 of 1889.
In the machines as at present constructed it sometimes occurs that "sorts"
accumulate in the channels of the composing cylinders and have to be removed by
hand an operation involving some loss of time. To obviate this there is provided in
every tenth or in other convenient channels of the distributing cylinders plugs or
weights and spiral springs similar to the weights and springs described in the
Specification of the application for Letters Patent No. 12617 of 1889 but in the said
tenth or other channels the plugs or weights are longer and the springs are shorter
than they are in the rest of the channels. When "sorts" accumulate in any of the
channels of the composing cylinder a part of the type therein may be run up into one
of the channels in the distributing cylinder provided with the longer plugs or weights
and shorter springs.
The spiral springs in the distributing channels have hitherto abutted against screw
plugs in the head plate of the distributing cylinder. To avoid the complication of so
large a number of screw plugs the upper ends of the channels are covered with an
annular abutment plate which is held in position by clamps. In the said abutment
plate there is a hole (or more than one if preferred) closed by a removable plug.
When it is desired to remove any particular spring the clamps holding the annular
plates are loosened and the plug is removed; the plate is then turned until the bole
is above the spring which may then be withdrawn through the hole. Instead of
clamps for holding the abutment plate it may be held by guides which prevent
vertical movement of the plate.
In order to facilitate the entrance of the types from the channels of the distributing "
oylinder to the channels of the composing cylinder the entrances to the composing
channels may be slightly opened or bevelled.
Instead of driving the separator rollers independently of the vertical driving shaft
they are driven from the band which drives the packer shaft in a more simple
manner than heretofore. A horizontal pulley is mounted in contact with the band
driving the packer shaft. The upper end of the spindle of the horizontal pulley
terminates in a square or other noncircular form upon which fits a correspondingly
recessed or shaped lower end of a vertical shaft geared with the separator rollers.
This arrangement enables the separator rollers to be lifted away from the apparatus
at once.
The hammer by means of which the types are fed forwards into the packer is
reciprocated twice for every revolution of the packer shaft by means of a duplex
cam.
t
The outer end of the roller carrying the travelling band below the packer runs in
a bush which is held in place. by a collar on a screw which collar carries a hook
which engages with and holds down the "gate."
The shield which covers the face of the types in the curved path of the packer is
.

page_text: held downwards in the covering position by a spring bearing on a rectangular boss.
This spring holds the shield botir in the open and in the closed position.
In place of a dabbing brush or similar device for driving the types to the bottom
of the type way on emerging from the packer a soft of. roller is used and it may be
provided with an 'indiarubber surface bearing upon the faces of the types.
The types as they enter the quadrant, or curved, path in the packer are held and
guided by three rollers. Of these rollers two are constructed of rubber or
the like
and engage respectively with the heads and feet of the types the roller engaging with
the feet of the types being mounted in a swing frame. Below the rubber rollers, is
an intermediate hard metal roller mounted in a swing frame and operating to bring
each type into position to be lifted into the curved typeway.
A spring friction bar may in some cases be substituted for the brush in the type
way. This friction bar has two springs fixed upon one side and its other side forms
part of the typeway. The bar is arranged so as to be capable of a slight motion
tending to widen, or narrow, the typeway and the tendency, of the springs is always to
narrow the typeway and thus to put friction upon the types, in their passage to the
justifier.
+24
Above the driving pulley of the travelling band a smaller pulley is mounted between.
which and the driving pulley, the travelling band passes. This ensures a larger, arc of
contact and a more positive drive. To prevent the slack of the travelling band from
being carried round by; the pulley a pin is fixed below. the band and between it and
the pulley. The travelling band both in its passage to and from the packer passes,
above the cover of the driving disc on the vertical shaft. The, two parts of the band.
are separated by a spring strip which prevents their frictional contact. The travelling.
band is protected by, covers which, may be removed at, one operation and which are..
constructed to prevent the types from being accidentally carried backward by the
retreating, part, of the travelling band. This construction, and arrangement permits
the travelling band to be removed and replaced in a very short time when desired..
and it is generally more convenient than the former arrangement.

I, HUGH HAMILTON Managing Director of The Type Setting Syndicate Limited
of 2 Copthall Buildings in, the City of London do hereby declare the nature of this
Invention which has been communicated to me from abroad by The Thorne Machine.,
Company of 32 Vesey Street New York in, the United States of America and in
what manner the same is to be performed to be particularly described and ascertained 4
in and by the following statement:
-
This Invention relates to improvements in the type setting, and, type distributing,
machines of the type described in the Specification of,, Letters Patent Nos. 3921, of
1880, 14517 and 14518.of 1887, 3918 of 1888 and 12617 of 1889.
I will particularly describe my present improvements with reference to the accom. 4

In the machines as at present constructed it sometimes occurs that "sorts"
accumulate in the channels of the composing cylinders, and in order to avoid blocking
the machine, these sorts have to be removed by hand when they accumulate, an opera-
tion involving some loss of time. In order to obviate this delay and inconvenience
there is provided in every tenth or, in other convenient channels of the distributing
cylinders of the machines, plugs or weights and spiral springs, similar to the weights
and springs described in the Specification of the Letters Patent No. 12617 of A.D. 1889,
but. in the said tenth or other channels, the plugs or weights are longer and the
springs are shorter than they are in the other channels. This is illustrated by Figure 1,
which shews one of these channels in vertical section. In consequence of this arrange-
ment, when sorts accumulate in any one of the channels of the composing cylinder a
part of the type therein may be run up into any one of the channels in the distributing.
cylinder which is provided with the shorter spring 6 and longer weights.

In the said
The spiral springs 6 in the distributing channels have hitherto abutted at their upper.
ends against individual screw plugs in the head plate of the distributing cylinder. To
avoid the complication of so large a number of screw plugs the upper ends of the
channels are covered with an annular abutment plate which is held in position by
clamps as shewn in section in Figure 1, and in plan in Figure 2.
abutment plate there is a hole (or more than one hole if preferred) closed by a
removable plug f³. When it is desired to remove any particular spring from the
channels of the distributing cylinder, the clamps which hold the annular plate fare
loosened and the plug f³ is removed, the plate is then turned until the hole from
which the plug is removed, is above that spring 6 which it is desired to remove, the
spring may then be withdrawn through the plug hole. Instead of employing clamps
for holding the abutment plate, guides or similar devices arranged to prevent vertical
motion of the plate may be used.
In order to facilitate the entrance of the types from the channels of the dis-
tributing cylinder into the channels of the composing cylinder, the entrances at the
upper ends of the channels of the composing cylinder may be slightly opened or
bevelled.
Instead of driving the separator rollers k k independently of the vertical driving
shaft, they are driven from the band / which drives the packer shaft in a more simple
manner than heretofore as shewn in part sectional elevation in Figure 3. A horizontal
pulley gis mounted in contact with the band h. The upper end of the spindle of
the 'horizontal pulley 9 terminates in a square or other suitable non-circular form
(also shewn in Figure 4) upon which fits a corresponding shaped recessed or shaped
lower end of a vertical shaft ; a pinion fixed upon which is geared with pinions on the
axes of the separator rollers kk. This arrangement enables the separator rollers to
be lifted away from the apparatus with facility.
The hammer (which is shewn in Figures 5 and 6 in elevation) is reciprocated
twice, in each revolution of the packer shaft by means of a suitable cam l¹ as
indicated in the drawings, for the purpose of feeding forward the types into the
packer.
The travelling band at the end of its course nearest to the packer passes around a
bush Figure 6 which is mounted upon a stud or pin p (shewn also in Figure 10)
thus constituting a roller or bowl. The bush s is carried upon the vertical plate n by
the pin p which is secured thereto. This vertical plate receives a vertical reciprocating
motion from the eccentric e and the end of the travelling tape is consequently raised

page_text: and lowered together with the gate (Figure 10). To provide for the vertical
motion of the gate with that of the tape, a rocking arm m is mounted upon the pin p
and pivoted at its outer end. To this rocking arm there is fixed a table which
lies under and supports the tape, a fixed part q overlying the tape, and the hinged
gafe r. When the gate (Figure 10) is closed a narrow passage will be left between
the part and the gate sufficient for the passage of one type only at the same.
time. By this means the passage of more than one type simultaneously is prevented.
The pin p is drilled and tapped axially for the reception of the screwed pin t' to the
head of which there is secured a hook or catch which is capable of engaging with a
pin on the gater and thus of securing it in the closed position or of liberating it
when the gate is desired to be opened.
The shield a which covers the faces of the types in the curved path after
leaving the packer and which is shewn in end view in Figure 6 and in front
elevation in Figure 7 is held downwards in the covering position by a spring b
which bears upon a rectangular boss formed on the pivoted part of the shield.
The spring it will be obvious will tend to hold the shield in either the open
or the closed position and some effort will be required either to open or to close
it, thus preventing the possibility of damage or danger to the faces of the type by its
being accidentally opened or closed at improper times.
In place of a dabbing brush or similar device for driving the types to the bottom
of the typeway on emerging from the curved path after leaving the packer a soft
roller c Figures 6. 7 and 8 is employed and it may be provided with an india
rubber or similar elastic surface bearing upon the faces of the types. In Figure 8
the roller c is represented as being turned out of the way for the purpose of examining
the type. This may be provided for by mounting the roller upon a stud which is
pivotted on a pin to the bracket.
The types as, they enter the quadrant or curved path after leaving the packer are
held and guided by three rollers as shewn in Figures 6 and 7 of these rollers two
marked respectively d and d' are constructed of india rubber or similar soft elastic
material and engage respectively with the heads and feet of the types the roller d
engaging with the feet and being mounted in a swing frame i. In a lower plane
than that of either of the two soft elastic rollers is an intermediate metallic or hard
roller u also mounted in a swing frame and operating to bring each type into position
to be lifted into the curved type-way.
A spring friction bar may in some cases be substituted for the brush which is
at present used in the type-way. This friction bar Figure 9 (shewn in end view
and plan) has two springs a¹ x fixed upon one side and the other side forms one of
the walls of the type way. The springs a abut upon the outer fixed wall of the
type channel and they normally tend to narrow the type way between a and the inner
wall of the type channel and thus to put friction upon the types in their passage to
the justifier.
Referring to Figures 11 (an elevation) and 12 (a plan) it will be seen that
above the pulley y which drives the. travelling band there is mounted a smaller
pulley y' between which and the driving pulley the travelling band passes. This
ensures a larger arc of driving contact between the pulley and the band and
consequently a more positive drive. To prevent the slack portion of the travelling
band being carried around the pulley a pin y² is fixed. below the travelling band and
between it and the pulley y. The travelling band both in going to and returning
from the packer passes above the cover of the driving disc on the vertical shaft. The
forward and return parts of the band are separated by means of the spring strip
which prevents their rubbing contact this is also shewn in partial section in Figure 6.
The travelling band is protected by covers which may be readily removed and
which are constructed, and arranged to prevent the types from being accidentally
carried backwards, by the retreating part of the travelling band. This construction
and arrangement permits the travelling band to be removed and replaced in a very
short time when desired and it is generally more convenient than the arrangement in
the former machines.

shaft which gears into a worm wheel » upon the shaft of which is mounted the
first of a series of wheels w w by means of which the motion is communicated from
