HERBERT JOHN HADDAN, of the Firm of Herbert and Company, Patent Agents,
of 67, Strand, in the City of Westminster, Civil Engineer. "IMPROVEMENTS ON
MACHINES FOR DISTRIBUTING TYPE." A communication from abroad by William
David Creighton Pattyson, of Sherbrooke, Province of Quebec, Canada, Student of
Arts.
This Invention has reference to an electro-magnetic machine, by which the type
used in printing will be separated, and each particular character out of the column
deposited in a separate receptacle. Thus, all the capital letters A will be deposited
in one receptacle, all the small letters a in another, the capital letters B in another,
and so on. Figures also will have their proper receptacles.
The machine inay be arranged to sort out various kinds of type, as for instance,
from the roman characters, the italics, and blocks will not only be separated, but
also each particular character in each type will be deposited in its proper receptacle.
In the Drawings hereunto annexed similar letters of reference indicate like
parts, and,
Fig. 1 is an isometrical view showing, partly in section and partly in clevntion,
the general arrangement of my Invention.

Letter a is any suitable entablature, upon which the mechanism is erected; b is
the pedestal of the main portion of the mechanism which, as shown in the Drawings,
is made circular in form, and has in its centre a step c to receive the end of a shaft;
d, c, are thimbles or distance pieces supporting and maintaining at the proper height
above the plate b, the receptacle plate f, and receptacles g. Projections are formed
upon the plate f supporting the guide plate i; kare thimble or distance pieces
placed upon i supporting the selector ring with the cam ring attached to it; m are
thimbles supporting the guide n, in which the upper end of the shaft d revolves;
o and p are brackets carrying respectively the ends of the shafts q and 7; upon these
the thimbles are placed, carrying the inclined type table s. These parts are all
secured together by bolts passing through the thimbles and eyes formed in the
various parts, holding them together.
As the machines so far constructed, embodying this Invention, have only been
small ones, the above arrangement of attaching the parts in their relative positions
alone has been employed.
In constructing large machines I should prefer to change the system, so that as
far as possible, each part may be attached or detached from the framework without
disturbing any other, or by disturbing as few as possible. The extremity of the
shaft q is carried by a bracket t, and upon it are placed and secured in the position
shown, cams and v, loose pulley w, friction cone x, operated by a pivoted arm y.
This arm is provided with a second arm carrying an armature placed immediately
over a double coil of electro-magnets a². As before stated, the foot of the shaft t
is received in the step c, and immediately above it is secured upon the shaft da
ratchet wheel b² (see Figs. 14 & 15), the teeth of the ratchet being spaced all around
the wheel to agree with the equal distance of the extremities of the pusher bolts c².
The receptacle plate f is of circular form and provided with sufficient dead space d²,
the purpose of which will herein-after more particularly appear.
The balance of the space is divided into as many radiacal grooves as the machine
is intended to accommodate, different characters, numbers, and varieties of characters
of type with the exception of the last one a¹, which is for what is called the
"pi" box.
In the Drawings shown, the machine is arranged for sixteen characters only, and
the "pi" box. In these grooves the receptacles g, which consist of two sides and
a bottom, fit snugly so that they can be pushed in by hand, but are not in danger of
being moved by the action of the bolts c; e are type rests, one of which is placed in
each of the receptacles g, to keep the types which fall into them in nearly an upright
position. The bolts care attached to the receiver plate f by means of a ring f
placed concentrically with the receptacle plate f, and secured by bolts or screws. In
this ring grooves are cut, forming guides for the horizontal part of the bolts to
slide freely in, but made sufficiently tight fitting to maintain the upper extremity g
in its proper position. One of each of these bolts c² is provided for each of the
receptacles g.
It will now be seen that by turning round the wheel 62 in the direction indicated
by the arrow, Fig. 14, its teeth acting on the lower extremities of c will cause al

page_text: the bolts simultaneously to diverge and press into the receptacles g, thereby
pushing outward any type which has fallen in between them and the rests e", which
are placed near the inner extremity of the receptacle g. The bolts care caused to
converge at the passage of each of the teeth of the wheel be, by means of an elastic
band placed around their necks. Thus, as each character is received in g and
pushed back by g, the rest e recedes, sliding freely, and when the holt converges,
a new space is formed for the reception of the next character. The faces of the
rest and that of g, are inclined for the purpose of giving the type a slight incline
outwards, for should they be placed vertically and not stand fairly on their bases,
they might topple over and fall inwards, thereby obstructing the descent of the
next type.
The guide plate is constructed as follows:-In its contre a cylinder is formed,
having passages in it, to come immediately over the end of each of the recep-
tacles is a cam formed on the centre of i, as shown in Figs. 12 and 13;
through the centre opening in this the shaft de passes. Immediately above this is
secured on the shaft ( the distributor barrel m³, shown more particularly in Figs. 8,
9, and 10, having on its top rack teeth n to correspond in number with grooves o
formed on its periphery. These grooves are partially covered by plates p, leaving
a sufficient space for the projections of the selectors, which will be herein-after more
particularly described, to enter and "feel" or engage with the type. The dis-
tributor barrel is extended below the grooves, and on this extension small trap doors
or drop bottoms q are attached, being pivoted, and swinging freely on pins
screwed into the barrel of the distributor; s are small pins, passing, as shown in
Figs. 9 and 10, through the bottom extension of the distributor barrel, and so
situated that when any one of the drop bottoms is turned to a horizontal position,
and the pins & pushed out, the drop bottom is by it secured in that position. This
is done by the projection of the cam , the top of the cam & coming close to the
under surface t of the distributor bottom. Thus as the distributor barrel revolves
with the shaft & and the guide plate i and cam 2 are stationary, each of the pins f
are alternately pressed outwards as they pass the projection 2, the drop bottoms
being successively raised as the barrel m revolves by the projection n, which is
immediately over the dead space d on the plate f. It will be observed that there
are twenty grooves of in the barrel m². This is to cause the grooves in it to corre-
spond with the inner ends of the receptacles y, no matter in what position the
barrel may be turned to bring the grooves o² to agree with them, therefore the three
extra grooves are formed to occupy the space , the position of the projection &
of the cam, and the lifter u being so arranged that the pins s will be pushed out
after the drop bottom is raised to the horizontal, and before it is fully clear of the
projection On the shaft d immediately above the distributor barrel the pawl
lever is placed, the shaft & forming a pivot for it to rotate freely upon, having
on one extremity the pawl w to engage with rack teeth n on the barrel m² and
pawly to engage with the rack teeth on the cam ring 1; as is the selector ring,
which is stationary. This is made in two parts a³ and b³, as shown in Fig. 5, to
form a guide for the cam ring l.
In the selector ring 3 selectors care placed suitable in number to agree with the
receptacles Is and one over, the first one being for straightening the type in the
grooves o, and in position to agree with the grooves o2 of the barrel m², a space
being left in the circle they stand in agreeing with the dead space d². The par-
ticular construction of the selectors is more clearly shown in Figs. 5 and 7. A
hole is bored in the selector ring 63 for the reception of each selector; this hole
is of suitable diameter to receive the end 3 of the selector, and extends a distance
of equal diameter, as shown in Fig. 5, when the diameter is reduced to agree with
the body. By this means it fairly guided and held in position. To the body ƒ³
is screwed a head g³, and in it is inserted a pin working in a groove formed on
the under side of selector ring 3, and preventing the whole from changing its
position. In the space 3 a spiral spring is placed, pressing against the shoulder
formed by the enlarged end e³ at one end, and the shoulder formed by the decreased

page_text: diameter of the hole in 63 at the other. By this means the heads g³ are drawn up
closely to the inner surface of the ring b³.
is
The bodies f3 are hollow cylinders, and in the space existing between the end of
the head (screwed into them and a bolt 3 placed in them) a spiral spring
placed, the bore of the body being reduced in, the outer extremity, and a bolt ³
being provided with a head to fit the bores, as clearly shown in Fig. 7. Thus by
pressing on the outer end of the bolt 3 the spiral spring 3 is compressed and
pushes out the head g³, causing the spiral spring to be compressed. The pressing
in of the bolt is caused by the projections m³ of the cam ring as it is revolved
by the pawly on the lever v².
13
The heads are provided with projections ³, which engage with similar nicks
or notches o, formed in the type 2, which are at this time in grooves o², shown in
Figs. 8, 9, and 10. If the nicks o³ do not correspond with the projections n³ the
selectors will be prevented from passing inwards to their full extent; q3 is a
pin screwed into the bottom part of the head 93 and arranged exactly to agree
with the pins s². By reason of the projections n³ not agreeing with the nicks o
the pins 8, the spiral spring yielding to let the projection m³ pass the end of
the bolt, consequently the drop bottoms are not allowed to fall and the types
are retained in the grooves o2. Had the projections n³ agreed with the nicks o
the projections would have passed inwards until they reached the inner side
of the grooves o², and the pin q3 would have driven in the corresponding pin 82,
allowing the drop bottom q to fall, and by being releived by the passage of the pro-
jection n the spring carrying the selector back would allow the type to fall into
the corresponding passage in the guide plate i beneath it. By arranging the
nicks o and projections n³, and varying them according to the types, characters,
and figures, the types contained in grooves of will be carried around the barrel till
they come to the selector, having projections to agree with their nicks.
Although but two projections n³ are shown on the heads their number may
be increased or diminished, as well as their position varied, it being necessary
to have such a variation of nicks and projections that a different combination
will be provided for each type character in that type and figure. The pawl
lever is actuated by a connecting rod attached to a double eye upon the
lever and the pin of a crank upon the shaft q. By this arrangement the cam
ring and barrel m³ are alternately rotated in opposite directions.
The type table s is constructed as follows:-Upon it flanges 3, u³, are raised per-
pendicular to the plane of the table. These are for the reception of the type in
column requiring to be distributed. The galleys containing them are brought to
the table and the column removed and placed upon the table so that the first
line of type comes fair with the line of the pusher 3, the front of the column
being supported by an angle plate w", which in the case of unleaded type is
secured stationary by set screws or similar devices, but which in the case of leaded
type is only held sufliciently in place to support the leads as they are pressed
forward from the column, but is free to move when forced to do so by the action
of the back angle plate, as will be herein-after more clearly understood. This
back angle plate is actuated by a pawl attached on a slide bar In the
flange an opening is formed and the flange extended, as shown at at, Fig. 17,
forming a channel c¹, at the end of which a spout or conductor d' is attached. The
lower extremity of this is situated to come immediately over the groove o of the
distributor barrel m². In this extension of the flange an elastic cushion &* is placed,
as shown in Figs. 1 and 17, opposite which extensions of the flange care formed
carrying and supporting the separator d'. This consists of a plate of two thick-
nesses, forming shoulders upon it, having springs et attached on each shoulder. It
is also provided with projections f* for further guiding it, and is actuated by the
lever operated by a cam on a shaft carried by brackets attached or made
in one with the table s. This shaft is rolated by a worm gear and worm wheel m
upon the shaft 7. The angle plate and pusher 23 are both operated by a worm
wheel n working in the teeth of a worm gear o. This worm gear is secured on

page_text: the lower end of a spindle ps passing through a sleeve q' in the table s, above
which is secured on the spindle a collar, having a cam projection engaging with
a hook on the end of the bar 3 (see Fig. 16). Again, above the collar upon the
spindle p is secured a gear wheel 8, the teeth of which only extend two-thirds
around the circle, and engage with the rack teeth th on the pusher bar 3, the above
gears being so arranged that the shaft makes one revolution for each of the rack
teeth t' on the pusher bar 3, and as the cam h is provided with five projections;
the separator operates five times to each revolution of the shaft is a pro-
jection on the pusher bar extending through a slot a" in the arm v', and is connected
by a spring a to a stop w' on the arin. This spring causes the pusher to return as
soon as the teeth of the wheel s' are clear of the teeth t'.
The inclination of the table s is for the purpose of causing the line of type as it
is placed in front of the pusher bar to rest fairly against it or "on their feet,"
and to obviate any danger of their toppling over when approaching the conductor
d, and obstructing the advance of the line of type. The bar is provided with a
projection, to which an elastic or spiral spring y' is attached, connecting it with
a projection on the table 8, and drawing it back to a stop a³. 65 and c are two
poles connected with an electrical battery insulated from each other, and 65, being
provided with an insulator head fl which acts upon the periphery of the disc u,
causes the poles to touch at and the contact to be maintained during about three-
quarters of the revolution of the disc, the rod 65 being made sufficiently flexible or
elastic to recover its upright position after the step e³ has passed the head 1, thus
separating the poles and c. The position of the notch e being, as shown in
Fig. 20, close to the end of the pole b, the disc v will be secured on the shaft in
such a position that the notch on it f³ will be about ten degrees behind in the
circle of the disc's periphery of coming in contact with the stop of the
armature. is an elastic band or other spring for drawing back the arın y
operating the friction clutch a. On the back of the loose pulley w projections 15 are
formed to engage with an arm on the friction clutch x, to assist the friction
surface in revolving the shaft q.
The friction cone is attached to the shaft by a key or feather in the ordinary
way of allowing it to slip freely longitudinally on the shaft, while it obliges the
shaft to revolve with the cone. Thus it will be seen that when the inaguets a³
attract the armature with sufficient force to overcome the spring 15, the army
thrusts the friction cone a forcibly into the loose pulley v, and the shaft q is caused
to revolve. is a standard carrying a pivoted lever m³ made of superabundant
weight towards its outer extremity, and causing its point which enters between the
grooves o and drop bottoms q of the barrel m² to be elevated and press slightly
against the bottom of the grooves o. The inner extremity of the lever is so
situated that it comes fairly under the groove of at each pause of the revolution of
the barrel m n³ is a standard carrying a screw o³, adjusted so that when the
inner point of the lever m³ is depressed and caused to rest on one of the drop
bottoms q the outer extremity of the lever touches the end of the screw o. The
screw o and the lever m³ are poles of the same battery as the poles b and c for
the purpose of completing the circuit by connecting the lever m with o when the
circuit is broken by the separation of the pole 5 from pole c² In constructing the
lever m³ the superabundant weight of its outer extremity is only such as to cause
it to fall down readily from the screw o, but when a type in one of the grooves o
rests upon the inner end of the lever its weight brings the outer end in contact
with the screw o. The wires of the battery will be arranged in any ordinary
manner readily understood by any electrician of ordinary skill. One of the wires
of the pulley is connected at 7, and a connection is made from it to c³. The other
battery wire is connected at s", thence running through the magnets a² and passing
from them to the pole 65, standard 1, and lever m³ ³ is a pulley on the shaft r,
connecting by any suitable belt with the pulley w.
The operation of my Invention is as follows:-The "forme," after use in the
printing press, is placed upon the inclined table s. The shaft is rotated by any

page_text: suitable power in the direction indicated by the arrow in Fig. 3, rotating the worm
wheel m attached on its extremity, engaging with the worm gear 1, and rotating
on the shaft it in the proportion of twenty-two revolutions of the shaft to one of
the shaft it, consequently the worin gear nt, revolving with the shaft it, drives by
means of the gear of the spindle, 2 revolving the collar and wheel 8', the teeth
of the latter engaging with the rack teeth th of the pusher v³, causing it to drive
the line of type then in position towards the tube d, down which each type falls
separately, and is received in one of the grooves o of the distributor barrel m².
Before, however, the type can reach the tube it has to pass the separator d',
constantly working its inner end pressing on the type each is forcibly pressed
into the elastic cushion bt, thereby separating it from the next character following,
in case they should be stuck together by printing ink, &c.
It will be observed that the separator d' acts a great many times to a very small
motion of the pusher bar, so that each type in passing will thereby be forced
several times on the cushion b, ensuring its separation. By this arrangement the
types are ensured to drop separately or singly down the tube as they come to it,
which falling into one of the grooves of they strike the inner end of the lever m³,
causing the opposite end of it to come in contact with the screw o, connection
with which and the lever m³ completes an electrical circuit, bringing into action
the power of the electromagnets a², causing the army to bring the friction cone a
into operation, and rotates the shaft 7 and crank 83, which latter in its forward
motion, by means of the arm and pawl w², causes the barrel m² to advance the
distance of one groove in its circular movement, bringing an empty groove imme-
diately under the tube to receive the next type as it drops. The lever m³ thus
releived of the weight of the type ceases to be in contact with the screw of The
electrical circuit is however still complete by means of the electrical pole 5 being
pressed by the cam disc u against the pole c until the notch con releases the
spring pole from contact with the pole c. The electrical circuit being then
entirely destroyed, the armature is released from the magnets a² by the spring,
the army disengages the clutch, the stop g on the armature rising simultaneously
and engaging with the notch f5 of the disc v. This prevents any further revolution
of the shaft q until another type drops upon the lever m. The notch e is so
placed on the cam disc that the electrical circuit is severed on the instant the
crank s has completed its entire revolution.
The return half of the revolution of the crank s³, by means of the lever and
pawl, causes the cam wheel to travel the space of one cam, which movement
presses simultaneously into action all the selectors c, one of which is required for
each character in the class of type to be distributed. A dead space s¹, equal to
that required for three selectors, is appropriated to the operation of the lifter u²,
the cam, and the working of the lever m³. The last selector t being a detected
opener which opens any box containing a type which may have escaped the action
of its proper selector, in which case it will be received by the receptacle a
appropriated to "pi." This selector differs from all the others in that in has no
projections n for engaging with the type.
The action of the selectors is as follows:-The type used with this machine
differs from that ordinarily in use only in that each character in the "font" has
its on peculiar arrangement of nicks in lieu of those at present placed on the
side of the type for the convenience of the compositor. The dead space & above
referred to agrees with the dead space d in the receptacle plate f. The required
number of selectors, each provided with projections n³ to correspond with the nicks
on the single type allotted to that particular selector, are uniformly arranged
around the stationary ring b³, concentric with the barrel m², in such a manner that
the vertical line of nicks o" in the type contained in the grooves o is in each case
directly opposite to the vertical line of projections n³ on the selector heads g³, so
that when the cam wheel 7 presses against the bolts the springs are compressed
and the projections n³ enter the corresponding nicks o³ in the type, which allows
the pin g to push back the sliding pin 8, so permitting the drop bottoms g² to

page_text: fall. Projections 3 of the cam wheel then passing the bolts, the projections
n retire with the selector by the action of the spring 3, thus having the type
unsupported, allowing it to pass through its groove in the plate i and rest in its
receptacle tube g, which is placed directly under the guide to receive it when it is
acted upon by g in the manner herein-before described. When any of the
receptacles become full they are removed, and empty ones put in their place.
The small spring u is attached to the head g³ of the selectors with the exception
of the first one v¹, this selector is for the purpose of straightening up the type in
the grooves o before it is acted upon by the other selectors. The springs are
for the purpose of preventing the type from being displaced by the friction of the
projections when they withdraw from the notches o³. After each groove o² has
passed the detecting opener t', its drop bottom q is raised by means of the stationary
projections to its proper level, which being attained the projection & forces the
sliding pin sout to support it, to receive the type from the tube d. After a line
of type has been removed by the pusher from the front of the column, the
wheels has revolved till the blank space in its periphery has come opposite to the
pusher, thus allowing the pusher to fly back by the action of the spring a², at the
same time the cam projection on the collar engages with the hooked end of
the slide bar 3 drawing it forward, and by the action of the pawl y³ on the rack ¹
(see Figs. 1 and 16) draws forward the angle plate 23 the length of one rack
tooth. The rack teeth are made equal in length to the space of one line of type,
or one line of type and the leading, should they be leaded, and thus bringing
forward the next line of type in the column to be acted upon by the pusher v³.
After the cam projection on the collar has revolved a sufficient distance to clear
the hook, in doing which it brings up the next line of type in front of the pusher ",
it is brought back by the action of the spring y' till the projection comes in
contact with the projection a³.
