PROVISIONAL SPECIFICATION.
Improvements in Type-setting and Distributing Machines.
1, JAMES YATE JOHNSON of 47 Lincolns Inn Fields in the County of Middlesex,
Gentleman do hereby declare the nature of this Invention which bas been com-
municated to me from abroad by The Thorne Machine Company of 32 Vesey Street,
New York in the United States of America incorporated under the Laws of the
State of New York to be as follows:-
This Invention relates to improvements in type setting and distributing machines
the said improvements being especially applicable to machines of the class described
in the Specifications of Letters Patent Nos. 14517 and 14518 of 1887 and 3918 of
1888. The improvements constituting the present Invention relate more especially
to the distributing part of the mechanism.
One feature of the present Invention relates to a means for feeding the lines of
matter to be distributed downward in the channels of the distributing cylinder and is
designed as a supplement or aid to the followers shown in the aforesaid Specifications.
Another featuro of the invention relates to a means for preventing the type from
working outward in the channels of the distributing cylinder, thereby enabling the
fenders described in the aforesaid Specifications to be dispensed with.
Another feature of the invention relates to a means for sustaining the distributed
type for a certain length of time at the upper ends of the channels of the composing
cylinder in order to afford a support for the incoming type until they are presented
squarely above the channels and in register with the wards thereof.
Another feature of the invention relates to a means for preventing the thinner
type from turning as they enter and pass downward in the channels of the composing
cylinder, thereby dispensing with the foot nicks and wards heretofore employed for
that purpose and at the same time insuring a more certain descent of the type
without danger of their becoming tilted so as to bind in the channels.
The distributing cylinder is provided with vertical channels into which the lines of
matter to be distributed are introduced in the manner described in the aforesaid
Specifications and the composing cylinder is provided with channels which register
with the channels after each step of the movement of the distributing cylinder. The
types operated upon are nicked in their sides and the channels of the composing
cylinder are provided with wards corresponding to the nicks in the type which
determine the distribution by causing the type to enter the proper channels and no
others.
The types tend by reason of their gravity to fall to the bottoms of the channels of
the distributing cylinder, thereby causing the lines of type to settle in the channels
as the successive type are distributed from the lower ends of the lines.
It has been found in practice that when the channels of the distributing cylinder
are full or nearly full the weight of the line of types is sufficient to cause it to pass
downward as the successive types are removed from its lower end, but as the line
decreases in height it is correspondingly decreased in weight so that at the time a line
is partly or nearly distributed the weight of the types in the line is not sufficient to
cause them to move downward with the required degree of certainty.
An attempt was made to overcome this difficulty by providing auxiliary followers,
which could be inserted after the line of type in the channels of the distributing
cylinder had been partly distributed and thus increase the weight above said lines so
as to cause them to pass downward with certainty. It has been found that better
results can be accomplished by subjecting the lines of type in the distributing
cylinder to a yielding spring pressure, which tends constantly to force them down-
ward in the channels

page_text: For this purpose the channels are cored out so as to provide chambers for the
reception of long spiral springs which are inserted through openings in the head
plate of the cylinder and are held in position by means of screw plugs which are
inserted into the said openings after the springs are in position. Interposed between
the lower ends of the springs and the types are followers which rest upon the types
and receive the pressure of the springs and also by the reason of their weight serve
to aid the springs in forcing the type downward. The followers consist of flat pieces
of metal which substantially fill the channels in cross section and are of such length
that when raised to the tops or near the tops of the channels there will be sufficient
room beneath them for a line of types of the desired maximum length.
It is of course necessary to provide means for preventing the type and the followers
from working out of the channels of the distributing cylinders and this in the
arrangements described in the Specifications herein before referred to has been
accomplished by means of fenders which were arranged around the distributing
cylinder and extended downward in front of the several channels. Theso fenders
were somewhat objectionable in practice because they added to the complication of
the machine and because it was necessary to remove them in order to introduce the
lines of matter into the channels of the distributing cylinder.
These fenders are dispensed with in the present arrangement and for the purpose
of retaining the followers are provided with lateral guides or projections which enter
the recesses in the sides of the channels which are cored out to receive the aforesaid
springs. These guides or projections may be formed in several ways for instance the
upper sides of the followers are provided with recesses into which fit cylindrical or
substantially cylindrical blocks which are interposed between the springs and the
followers and are of a width sufficient to extend into the recesses in the sides of the
channels and thus prevent the followers from moving outward in the chanuels.
In order to permit the followers to be removed from the channels when it becomes
necessary to do so for any purpose the aforesaid blocks are provided with openings
into which a rod or pin can be inserted from the front of the channel so as to raise
the said blocks against the tension of the springs to a position above the followers.
The followers can then be removed from the channels without obstruction.
If in any case it should be preferred to dispense with the blocks the followers may
be provided with laterally projecting studs which enter the aforesaid recesses and
thus prevent the followers from moving outward in the channels.
In order to provide for the removal of the followers when they are thus constructed
the channels are provided at a suitable height with horizontal recesses which communi-
cate with the first named recesses. By raising the followers until the studs are
opposite the horizontal recesses the followers can readily be withdrawn leaving the
springs in the channels.
When the followers supplemented by the springs are employed in the channels of
the distributing cylinder, as just described, the types will have very little tendency
to move outward in the channels and therefore the use of the fenders for retaining
the type in the channels can be dispensed with. In some cases, however, the types
will have a tendency to move outward and may sometimes move sufficiently outward
to prevent their wicks from properly registering with the wards of the channels of
the composing cylinder and thus prevent proper distribution. To counteract this
tendency and to restore the types to their proper positions in the channels of the
distributing cylinder in case they should move outward a yielding presser roll is
provided which extends vertically at the side of the distributing cylinder and in such
proximity thereto that as the cylinder is revolved and the vertical line of type
contained in each of its channels is carried by it the roll will act upon the ends of
the type and force inward any which have moved outward beyond the proper position
and thus restore them into position to register with the wards of the channels of
the composing cylinder. The said roll may be made of any suitable yielding material
which will not injure the faces of the type but will preferably be of a length equal or
about equal to three fourths the height of the distributing cylinder. This roll will
be journaled in bearings arranged in any suitable manner the lower bearing being
A

page_text: secured to the upper end of the composing cylinder or to a stationary part of the
framework and the upper bearing being formed in a bracket projecting from any
convenient part of the framework.
It is found in practice that as the type contained in the channels of the distributing
cylinder are carried over the channels of the composing cylinder there is a tendency
on the part of the lower type in the lines to drop slightly at its advance edge before
it has been brought entirely into register with the channel of the composing cylinder
and when this occurs the type is liable to wedge in the upper end of the channel of
the composing cylinder and thus may impede the operation of the machine or if the
type is a very thin one it is liable to turn and fall downward in the channel of the
composing cylinder edgewise.
To obviate this tendency it is desirable to retain one or more type in the upper
end of channels of the composing cylinder the upper surface of the last type which
has entered the channel being maintained flush with the top of the cylinder until
the next type is ready to enter the channel. By this means a bridge is formed which
prevents the tilting of the type as they pass over the channels as before stated. To
accomplish this the upper end of the composing cylinder is provided with a series
of friction blocks or fingers which are pivotted upon the outside of the cylinder
between the channels of the composing cylinder and are provided with springs the
tendency of which is to rock the blocks or fingers across the channels. The blocks
are so arranged that as they are thus rocked they engage with the sides of the
type or they project from the channels at a short distance below the upper ond
of the cylinder. The pressure thus exerted against the sides of the type is
sufficient to arrest them and prevent them from falling to the bottoms of the
channels. By this means several types are retained in the upper end of each
channel of the composing cylinder the upper side of the last type which enters the
channel being flush with the top of the cylinder so as to afford a bridge for the next
typo passing over the channel. As soon, however, as the proper type arrives above
the channel the weight of the line of type above it in the channel of the distributing
cylinder, together with the force of the follower and springs will overcome the friction
of the block or finger and force the said type and the ones beneath it downward in
the channel of the composing cylinder.
As the types are thus forced downward in the channel of the composing cylinder
they are successively released from the friction of the block or finger and fall to
the bottom of the channel, the block or finger being properly formed upon its
bearing edge to release the type at the proper time. Or there may be provided
a device consisting of a brush or yielding piece such as a rubber slip secured by
a metal washer and screw so that the rubber retains. types at the upper end of
the channels in the composing cylinder. After applying the device to the cylinder a
sufficient number of types are passed into the channels to fill the space between the
point of contact of the type and the rubber slip and the top of the cylinder then the
tension of the rubber is ailjusted so it will just suffice to hold the line of types and
also yield to the force of the weight with a single type under it. Thus each
succeeding type will have the preceding one for a foundation preventing it from
turning over.
In machines of this class it has heretofore heen found desirable in order to prevent
the thinner type from being turned and either binding or falling edgewise in the
channels of the composing cylinder, to provide the type with a foot nick and to
provide the channels of the composing cylinder with a corresponding ward, which
entered the nick and thus prevented the type from turning. This has been found
objectionable in practice for several reasons and it has been found that the necessity
for the foot nick and foot ward can be obviated and better results secured by
providing those channels of the composing cylinder which are designed to receive
the thinner type with a rib or projection located at the front of the channel and
arranged to bear against the side of the type near its face. The said ribs or projec-
tions extend nearly the entire length of the channels in the composing cylinder but
terminate a sufficient distance from the bottom of the channels to permit the type

page_text: to be ejected. These ribs are constructed with great nicety so as to leave exactly
sufficient space between them and the opposite wards of the channels to receive the
width of the types and permit them to descend squarely without permitting them to
tilt or turn edgewise. The ribs or projections retreat very slightly at their upper
ends so as to permit the type to enter the channels readily, but for the remainder of
their length they hold the type snugly against the opposite wards of the channels.
These ribs may be constructed in a variety of ways, one form, and that which in
many cases will be preferable, is one in which the rib is formed just within the
channel in the same manner as the wards of the composing cylinder channels. The
ribs may, however, be formed of plates secured to or set into recesses in the side
of the composing cylinder.

Improvements in Type-setting and Distributing Machines.
I, JAMES YATE JOHNSON of 47 Lincolns Inn Fields in the County of Middlesex
Gentleman 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 incorporated under the Laws of
the State of New York and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
This Invention relates to improvements in type setting and distributing machines
the said improvements being especially applicable to machines of the class described
in the Specifications of Letters Patent Nos. 14,517 and 14,518 of 1887 and 3918 of
1888. The improvements constituting the present invention relate especially to the
distributing part of the mechanism.
One feature of the present Invention relates to a means for feeding the lines of
matter to be distributed downward in the channels of the distributing cylinder
and is designed as a supplement or aid to the followers described in the aforesaid
specifications.
Another feature of the invention relates to a means for preventing the types from
working outward in the channels of the distributing cylinder thereby enabling the
fenders described in the aforesaid specifications to be dispensed with.
Another feature of the invention relates to a means for sustaining the distributed
types for a certain length of time at the upper ends of the channels of the composing

danger of their becoming tilted so as to bind in the channels.
In order to convey a full and accurate understanding of the several improvements
constituting the present invention I will now describe them more in detail, reference

Figures 11 and 12 are sections similar to that shewn in Figure 10 but repre-
senting modified constructions.
Figure 13 is a side view illustrating the second improvement hereinbefore referred
to and
Figure 14 is a cross section taken along the line 7 of Figure 13.
Figures 15 and 16 shew a modification of the arrangement shewn in figures 6. 7
and 8.
Referring to said drawings it is to be understood that A represents the dis-
tributing cylinder and B the composing cylinder of a type setting and distributing
machine of the class referred to, the composing cylinder being stationary and the
distributing cylinder moving with a step by step movement, as described in the
aforesaid Specifications.
The distributing cylinder is provided with vertical channels a into which the lines
of matter to be distributed are introduced in the manner described in the aforesaid
Specifications and the composing cylinder is provided with channels b which register
with the channels a after each step of the movement of the distributing cylinder A.
The types operated upon are nicked in their sides, and the channels of the composing
cylinder are provided with wards 2 corresponding to the nicks in the type which
determine the distribution by causing the types to enter the proper channels and
no others.
The types e tend by reason of their gravity to fall to the bottoms of the channels
of the distributing cylinder, thereby causing the lines of types to settle in the
channels as the successive types are distributed from the lower ends of the
lines.
It has been found in practice that when the channels of the distributing
cylinder are full or nearly full the weight of the line of types is sufficient to cause
it to pass downward as the successive types are removed from its lower end, but as
the line decreases in height it is correspondingly decreased in weight so that at the
time a line is partly or nearly distributed the weight of the types in the line is
not sufficient to cause them to move downward with the required degree of
certainty.
An attempt was made to overcome this difficulty by providing auxiliary followers,
which could be inserted after the line of type in the channels of the distributing
cylinder had been partly distributed and thus increase the weight above said lines so
as to cause them to pass downward with certainty. It has been found that better
results can be accomplished by subjecting the lines of type in the distributing cylinder
to a yielding spring pressure, which tends constantly to force them downward in
the channels.
For this purpose (see figures 1 to 5) the channels a are cored out so as to provide
chambers or lateral recesses for the reception of long spiral springs 3 which are
inserted through openings in the head plate d of the cylinder and are held in position
by means of screw plugs 4 which are inserted into the said openings after the springs
are in position or by a plate or plates covering the openings or in any other suitable
manner. Interposed between the lower ends of the springs 3 and the types c are
followers 5 which rest upon the types and receive the pressure of the springs and
also by reason of their weight serve to aid the springs in forcing the type downward.
The followers 5 consist of flat pieces of metal which substantially fill the channels in

page_text: 22
:
cross section and are of such length that when raised to the tops or near the tops of
the channels there will be sufficient room beneath them for a line of types of the
desired maximum length.
It is of course necessary to provide means for preventing the type and the followers
from working out of the channels of the distributing cylinders, and this, in the arrange-
ments described in the specifications herein before referred to, has been accomplished
by means of "fenders which were arranged around the distributing cylinder and
- extended.downward in front of the several channels. These fenders were somewhat
objectionable in practice because they added to the complication of the machine and
because it was necessary to remove them in order to introduce the lines of matter.
into the channels of the distributing cylinder.
These fenders are dispensed with in the present arrangement and for the purpose
of retaining the followers lateral guides or projections are provided which enter the
recesses 6 which are cored out in the sides of the channels to receive the guides or
projections and aforesaid springs 3. These guides or projections may be formed in
several ways, two of which are illustrated in the present case.
In the construction illustrated in Figures 1. 2 and 3 the upper sides of the followers
are provided with recesses into which and into the core or recess 6 fit cylindrical or
substantially cylindrical blocks 7 which are interposed between the springs 3 and the
followers and are of a diameter or width sufficient to fit freely within the recesses 6 in
the sides of the channels, as shewn in figure 3, and thus prevent the followers from
moving outward in the channels. The followers may also extend upwards behind the
springs.
In order to permit the followers 5 to be removed from the channels when it
becomes necessary to do so for any purpose the aforesaid blocks 7 are provided with
.openings 8 (Figure 3) into which a rod or pin can be inserted from the front of the
channel so as to raise the said blocks against the tension of the springs to a position
above the followers. The followers can then be removed from the channels without
. obstruction.
If in any case it should be preferred to dispense with the blocks 7 the followers may
be provided with laterally projecting studs 9 as shewn in Figure 4 which enter the
-recesses 6 and thus prevent the followers from moving outward in the channels.
In order to provide for the removal of the followers when they are thus constructed
the channels are provided at a suitable height with horizontal recesses 10 which
communicate with the recesses 6 as also shown in the said Figure 4. By raising the
followers until the studs 9 are opposite to the recesses 10 the followers can readily be
withdrawn leaving the springs in the channels.
When the followers supplemented by the springs 3 are employed in the channels of
the distributing cylinder as just described the types will have very little tendency to
move outward in the channels and therefore the use of the fenders for retaining the
type in the channels can be dispensed with. In some cases, however, the type will
still have a tendency to move outward and may sometimes move sufficiently outward
to prevent their nicks from properly registering with the wards of the channels of the
composing cylinder and thus prevent proper distribution. To counteract this
* tendency and to restore the types to their proper positions in the channels of the
distributing cylinder in case they should move outward one or more yielding presser
rolls 12 is or are provided (see Figures 13 and 14) which or each of which extend
vertically at the side of the distributing cylinder and in such proximity thereto that
⚫ as the cylinder is revolved and the vertical line of type contained in each of its
channels is carried past the roll it will act upon the faces of the types and force
inward any types which have moved outward beyond the proper position and thus
restore them into position to register with the wards of the channels of the composing
cylinder.
The roll or rolls 12 may be made of any suitable yielding material which will not
injure the faces of the types and will preferably be of a length equal or about equal to
.:three fourths the height of the distributing cylinder although it may be longer or
shorter. The roll or rolls will be journalled in bearings arranged in any suitable

page_text: manner, the lower bearing 13 (Figure 13) being secured to the upper end of the
composing cylinder or to a stationary part of the framework and the upper bearing 14
being formed in a bracket projecting from any convenient part of the framework.
It is found in practice that as the types contained in the channels of the distributing
cylinder are carried over the channels of the composing cylinder there is a tendency
on the part of the lower types in the channels to drop slightly at their advanced edges
before they have been brought entirely into register with the channels of the
composing cylinder and when this occurs the type is liable to wedge in the upper end
of the channel of the composing cylinder and thus may impede the operation of the
machine or if the type is a very thin one it is liable to turn and fall downward in the
channel of the composing cylinder edgewise.
To obviate this tendency it is desirable to retain one or more type in the upper ends
of many channels of the composing cylinder the upper surface of the last type which
has entered the channel being maintained flush with the top of the cylinder until the
next type is ready to enter the channel. By this means a bridge is formed which
prevents the tilting of the types as they pass over the channels, as before stated. To
accomplish this the upper end of the composing cylinder is provided with a series
of yielding friction holders or fingers 15 (Figures 6, 7 and 8) which are pivotted
upon the outside of the cylinder between the channels and are provided with
springs 16 the tendency of which is to rock or force the holders 15 across the channels.
The blocks are so arranged that as they are thus rocked they engage with the sides of
the type projecting from the channels at a short distance below the upper end of the
cylinder. The pressure thus exerted against the sides of the types is sufficient to
arrest them and prevent them from falling to the bottoms of the channels. By this
means several types are retained in the upper end of each channel of the composing
cylinder the upper side of the last type which enters the channel being flush with the
top of the cylinder so as to afford a bridge for the next type passing over the channel.
As soon however as the proper type arrives above the channel the weight of the line
of types above it in the channel of the distributing cylinder together with the force of
the follower 5 and springs 3 will overcome the friction of the holder 15 and force the
said type and the ones beneath it downward in the channel of the composing
cylinder.
As the types are thus forced downward in the channel of the composing cylinder they
are successively released from the friction of the holder 15 and fall to the bottom
of the channel the holder 15 being properly formed upon its bearing edge to release
the type at the proper time.
Or there may be provided an equivalent device (shewn in Figures 15 and 16)
consisting of a brush or yielding piece 1 such as a rubber strip secured by a metal
washer 2 and screw 3 so that the said yielding device retains types at the upper ends
of the channels in the composing cylinder and prevents thin types from turning or
being turned over as they enter their respective channels which is effected in the
following manner. After applying the device to the cylinder a sufficient number of
types is passed into the channels to fill the space between the point of contact of
the type and the rubber slip and the top of the cylinder then the tension of the
rubber is adjusted by means of a bodkin or like device by pushing forward or
backward as the case may require so that it will just suffice to hold the line of
types and also yield to the force of the weight with a single type under it. Thus
each succeeding type will have the preceding one for a foundation preventing it
from turning over.
In machines of this class it has heretofore been found desirable in order to prevent
the thinner types from being turned and either binding or falling edgewise in the
channels of the composing cylinder to provide the type with a foot nick and to
provide the channels of the composing cylinder with a corresponding ward which
entered the nick and thus prevented the type from turning. This has been found
objectionable in practice for several reasons and it has been found that the necessity
for the foot nick and foot ward can be .obviated and better results secured. by

page_text: providing those channels of the composing cylinder which are designed to receive
the thinner type with a rib or projection 17 Figures 9, 10, 11 and 12 arranged to
bear against the side of the type. The projecting ribs 17 extend nearly the entire
length of the channels in the composing cylinder, but terminate a sufficient distance
froin the bottom of the channels to permit the type to be ejected. These ribs are 5
constructed with great nicety so as to leave exactly sufficient space between them
and the opposite sides of the channels to receive the width of the type and permit
them to descend squarely without permitting them to tilt or turn edgewise. The
ribs or projections 17 retreat very slightly at their upper ends so as to permit the
types to enter the channels readily but for the remainder of their length they hold
the types snugly against the opposite walls of the channels. These ribs may be
constructed in a variety of ways, one form, and that which in many cases will be
preferable, is that illustrated in Figures 9 and 10 in which the rib is formed just
within the channel in the same manner as the wards 2. The ribs may however, be
formed of plates set into recesses in the side of the composing cylinder, as indicated
in Figures 11 and 12 or they may be otherwise suitably secured to the cylinder.
The constructions illustrated in Figures 11 and 12 are substantially the same and
are the equivalent of the construction illustrated in Figures 9 and 10.

tion and in what manner the same is to be performed I declare that what I
