Improvements in Type Composing and Casting Machines.
I, OLIVER IMRAY, of Birkbeck Bank Chambers, Southampton Buildings, in the
County of London, Chartered Patent Agent, do hereby declare the nature of this
invention (as communicated to me from abroad by the Monoline Composing Com-
pany, of Washington, in the District of Columbia, United States of America,
Manufacturers of Type-setting and Line-casting Machines) 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 the Manoline type composing and
casting machine of the kind described in Patent No. 17135, September 2nd, 1893.
In this machine the matrix bars are stored in their proper chambers in a
magazine, and are delivered in the order required and assembled in a line, the
necessary space bars being introduced into the line as it is being composed. A
line carriage engages the line of assembled or composed matrices and carries it
to a justifying mechanism by which the space-bars are expanded to justify the line
after which the line carriage shifts the line to the casting point where a printing
bar is cast. The mould is then moved to the ejector, by which the cast printing
bar is ejected from the mold between trimming knives and is deposited in a
galley. The line held by the line carriage at the casting point is released and
depressed by a depressor, and then the line-carriage is moved back to a distributor
the hooked ends of the matrix and space bars stringing themselves upon their
proper horizontal distributing wires which are subsequently elevated into such
position that a distributing pusher pushes the matrix and space-bars from the
distributing wires into their appropriate chambers in the magazine.
The chief objects of the present invention are:-
First To provide the front end of the magazine with a novel transparent cover
or door and means for holding it closed, for the purpose of conveniently and
quickly gaining access to the foremost or leading matrix and space-bars.
Second: To provide new and improved means for successively lifting the space-
bars to place them in the channel from which they are forced at the required
time into the assembly box.
Third: To provide new and improved means for forcing the space bars, when
lifted, into their delivery channel of the magazine and discharging them one at
a time, into the assembly box for insertion into the line being composed.
Fourth To generally improve and simplify the construction and operation of
the oscillator or bell crank lever frame, by which, among other things, the
assembly box ejector is operated and the slide gates for delivering the matrix
bars from the magazine channels are reset in operative connection with the finger
keys for subsequent movements to release the matrix bars required to compose a
line.
Fifth To provide means for automatically arresting the back stroke of the
oscillator after a finger key is operated, to prevent the rotary cam on the rear end
of the oscillator from being thrown at improper times into engagement with the

page_text: continuously rotating roller, whereby objectionable chattering or rapidly repeated
vibrations of the oscillator, incident to its rebounding or springing back when
thrown forward to reset a matrix bar delivery gate, are avoided and smoother and
more uniform actions are obtained.
Sixth To provide novel and simplified means for operating the ejector by
which the matrix and space bars are ejected from the assembly box into the line
raceway.
Seventh To improve and simplify the construction and operation of the
assembly box, and the yielding carriage or slide on which is mounted the yielding
line abutment for one end of the line which is being assembled or composed, and
to combine with these parts an audible signal for indicating when the line is
of approximately the proper length.
Eighth To provide the assembly box with means for preventing its jaws from
unduly separating or spreading, and for promptly closing the jaws when the
assembly box ejector is retracted to normal position.
Ninth To improve and simplify the attachments of the line carriage, by which
the line of assembled or composed matrices is carried to the justifier, the casting
devices and the matrix-bar distributor.
Tenth To provide a second release of the line carriage as the line is being trans-
ferred from the casting point to the distributor so as to enable the distributing
rods or wires to lift the line with greater facility.
Eleventh To provide a safety or secondary depressor to insure the correct
depression of the matrix-bars so that their lower ends are surely levelled, and their
hooked upper ends placed with accuracy in position to engage the distributing
rods or wires.
Twelfth To improve and simplify the devices by which the distributor levers
carrying the horizontal distributing wires are operated, whereby the hooked ends
of the matrix bars are not unduly clamped or pressed upon by the distributing rods
or wires when lowered to stand in a substantially perpendicular plane, one above
another, thus avoiding possible undue oscillating or swinging motions of the
matrix bars from front to rear of the machine as the distributing rods or wires
rise in a curved path and spread into a substantially horizontal plane to permit
the matrix and space-bars to be pushed from the rods or wires into the proper
chambers of the magazine.
Thirteenth To improve the pot supporting devices and provide a new and
improved casting pot by which overheating of the metal in the well thereof is
effectually avoided, and the well and its channel leading to the casting point are
immersed within the body of the molten metal, so that the metal in the well and
channel are not exposed to the direct action of the heating flame from the burner,
thus insuring a practically uniform temperature of the metal flowing into the mold.
Fourteenth To provide a new pot cut off for the automatic closing of the mouth
of the casting pot to prevent the passage of the metal into the mold if the line of
the matrix bars assembled is a "lose" line that is to say, if a line is of improper or
such length that it cannot be, and is not properly expanded by the space-bars, in
obtain a tight line in the line carriage.
Fifteenth To improve and simplify the mechanism by which the sliding mold
is moved to and fro whereby the more or less complicated system of levers under-
hanging the bed plate of the machine is avoided and the mold operating lever is
placed above the bed plate.
Sixteenth To improve and simplify the means whereby the pivotted mold
carrying frame, in which the mold slides, is moved to and fro relatively to the
front of the machine, the construction being such that this is effected by the
direct action of the casting pot and the more complicated devices of the former
machine for this purpose are dispensed with.
Seventeenth: To provide the machine with a novel recasting mechanism,
whereby any required number of printing bars may be cast from one and the
same line of assembled matrix bars.

page_text: Eighteenth To provide new and improved means for wiping the trimming
knives as the mold moves from the casting pot to the ejector which ejects the
cast printing bar from the mold between the knives.
Nineteenth: To provide a new and improved galley which can be conveniently
and quickly removed and replaced, and is in operative connection with a
vibrating finger actuated by the horizontally sliding mold for pushing the column
of cast printing bars a definite distance along the galley, whenever a printing
bar has been or is about to be ejected from the mold."
Twentieth To improve, simplify and render more satisfactory in action the
automatic stop mechanism by which the motion of the line shaft is automatically
stopped after one cycle of motions, or rather after the line carriage has travelled
from the assembly box to ne casting point and returned to normal position.
Twenty first: To provide new and improved means, of a simple and effective
character, for operating the clutch of the starting and stopping mechanism, 50
as to stop automatically the rotation of the main or line shaft after each cycle of
motions of the machine.
Twenty second: To generally improve, simplify and render the Monoline com-
posing machine more effective reliable and satisfactory in practical use for the
production of type-high printing bars possessing the high perfection desired in
the printing art.

The several parts of the machine will now be described.
THE MATRIX BARS AND SPACERS.
The matrix bars and the space-bars are essentially the same
as those
in the former monoline machine, and may be produced in any suitable
manner, but the matrix bars are preferably made on the system known as
W. S. Scudders, by first obtaining from a line of fixed types, by electro-
deposit of metal, an accurate master matrix bar, casting from this bar a solid
type line or slug bearing relief characters, adjusting the relief of the type line or
slug accurately with relation to recesses formed in one edge of a blank matrix
bar, and reproducing the relief characters in intaglio form in the recessed edge
of the blank matrix bar by electro-deposit of metal, such as copper.
THE MAGAZINE AND MATRIX BAR DELIVERING MECHANISM.
As in the former monoline machine the magazine is divided by
vertical partitions extending in the direction of the length of the machine
into eight matrix bar chambers, 1 to 8 inclusive, and al space-bar
chamber 9, best seen in Figures 11, 12 and 27. These chambers are
provided in their upper parts with supporting guide rails or wires 10
running lengthwise of the chambers, upon which the matrix and space-bars are
suspended by their hooks, the guide rails or wires inclining down toward the
delivery channels of the magazine. The matrix bar chambers terminate at
their delivery ends in separate narrow channels 12, which extend in a line at right
angles to the chambers. The matrix bars move along the inclined guide rails
or wires and enter their respective delivery channels to be fed forward, one by
one, to the delivery point at the front end of the channel, whence they are caused
to enter the assembly box. The matrix bars are fed and delivered in the order
required by horizontal delivery gates 13, Figures 2 and 3, which at their tips
or front ends 14 constitute supports for the lower ends of the leading matrix bars.
The matrix bars in the delivery channels are moved forward until the front
matrix bars slightly fall and rest upon the tips or front ends of the delivery
gates, and when these gates are released and move rearward the front matrix bars,
being unsupported, rapidly descend. The delivery gates are each provided with
a thin upright matrix bar feed finger 15, which moves in a matrix bar channel and

page_text: when a gate moves rearward this finger also moves rearward and passes the mouth
of the matrix bar chamber communicating with said channel, thereupon a matrix
bar descends by gravity from the chamber into the channel, and when the gate
moves forward the finger pushes forward the line or bank of matrix bars in the
channel and places another bar upon the tip or front end of the gate to take the
place of the one previously delivered to the assembly box.
The delivery ends of the matrix bar channels 12 are covered by a transparent
door 12ª, set in a frame, Figures 2 and 27, which is hinged at one vertical edge
to the right hand vertical corner of the magazine and is adapted to bodily swing
open as shown in Figure 27 for free access to the delivery ends of the channels 12,
or to the foremost matrix bars therein, and to the foremost space-bar, which latter
is exposed through a narrow vertical space in the delivery channel of the space-
bar chamber. The door when closed is held by a vertically movable slide 1b
having oblique slots through which pass pins, the construction being such that
the slide descends by gravity towards the door to lap over its edge. If the door
is open and is swung to the closed position its free edge strikes a small angular
bracket 12 on the slide and this is caused by the pins and oblique slots to move
up and to the left until the door passes the slide and is closed, whereupon the
slide descends by gravity and holds the door closed.
Each of the delivery gates is swiftly moved rearward through the medium of
a spring 16, and is held in its forward position against the tension of the spring
by a pawl 17 pivoted centrally between its ends and having a hooked rear end 18
engaging a lug 19 on the delivery gate. The front end of the pawl is acted on
by a spring which tends to throw the hooked extremity of the pawl upward into
engagement with the lug on the gate, and the pawl is disengaged from the gate,
when a key of the keyboard 19, Figures 1, 2 and 36, is touched, through the
medium of a pivoted spring pressed detent lever 20, Figures 2 and 3, having an
arm 21 provided with a rounded portion bearing against a rounded part on the
front end portion of the pawl. The provision of the pawls 17 to hold the matrix
. delivery gates set or in their advanced position, and the actuation of these pawls
through the medium of the detent levers, are improvements which secure a more
delicate and quick release of the delivery gates, and obtain a smoother action
of the parts which are under control of the finger keys.
As in the former machine there is employed in the present machine an assort-
ment of ninety six different characters and ninety six different keys in the key-
board, one for each character. The characters of the matrix bars are divided into
groups of twelve, a different group being carried by each different species of
matrix bar, and as each species is in a separate chamber controlled by a delivery
gate, twelve finger keys appropriate to the twelve characters of any one group
of matrix bars is susceptible of controlling one and the same delivery gate. This
is effected by connecting the detent levers 20 with the slides 20", Figures 1 and 2,
that are actuated by the finger keys, as in the former machine. The slides 20°
serve to advance the stop bars 56 by which the descent of the matrix bars is
arrested, as in the former Monoline machine.
As shewn in Figure 12, the extreme left hand matrix bar delivery channel is
considerably shorter than all the others and ordinarily such channel only contains
a single matrix bar. To effectually prevent back motion of this matrix bar when
the delivery gate of the short channel springs rearward to permit the matrix bar
to descend, the wall of the space-bar chamber, which forms the left hand side of
the short channel, is provided with a vertical latch or pawl plate 10°, Figures 7, 13,
and 17, having a broad bevelled nose pressed outward by springs. When the
delivery gate is advanced, its upright finger forces the matrix bar past the bevelled
nose of the latch or pawl plate and it engages, retains and assists in supporting
the matrix bar in a perpendicular position, in such manner that when the delivery
gate springs rearward to release the matrix bar, the bar cannot move back with
the gate. The same conditions do not exist as regards the other delivery channels,
as there is always a number of matrix bars in each of these channels which is

page_text: sufficient to resist any tendency of the leading matrix bars to slightly move back
with the gates when they are released.
The matrix bar channels of the magazine are each provided with an accelerating
ever 22, Figure 3, thrown into action by a spring when the corresponding delivery
gate is released, for the purpose of suddenly acting on the delivered matrix bar,
accelerating its descent, and swiftly shooting it into the assembly box. The
delivery gates require to be reset in operative connection with the pivoted pawls 17,
and consequently with the keyboard mechanism, each time they have been released
and moved rearward, which is accomplished by the new oscillator, as will now be
described:
THE OSCILLATOR.
In the back motion of each delivery gate, it comes in contact with a part
of what in the former machine was known as a bell crank lever frame, which
has been materially improved; and will hereinafter be termed the oscillator.
This oscillator 23, best seen in Figures 2, 3, 5 and 6 comprises a frame composed
of two side plates suitably pinned together. The side plates referred to are
pivoted near their centres upon a shaft 24, in such manner that the frame can
oscillate to and fro, its upper end moving forwards, as its lower end moves back-
wards and conversely. The oscillator is provided with rear projections approxi-
mately in line with the shaft 24 to support a shaft 25 on which the rotary cam 26
is mounted. The upper end of the oscillator is provided with a pin 27 on which
are mounted double armed levers, each comprising a downwardly projecting
arm 28, and a forwardly projecting arm 30, the latter being, respectively, coincident
with the respective delivery gates. The downwardly projecting arm 28, of each
lever is connected with a spring 31 which normally tends to force this arm against
a rear stop pin 32, thus causing the lever to normally stand as shown in Figure 3.
The number of double armed levers is equal to the number of delivery gates,
that is to say there is one lever for each gate, and since the present machine,
like the former machine, contains eight delivery gates, there are eight levers
provided. The upper end 29 of the oscillator is adapted to engage a rocking stop
dog, composed of a bar 33 on a rearwardly projecting portion 34, pivotted to plates
attached to the rear of the magazine and having a depending portion 35 lying in
the path of the rear ends of all the matrix bar delivery gates, the construction
being such that when the parts are in the normal position represented in Figure 3,
the upwardly projecting end 29 of the oscillator is engaged by the stop dog 33,
and the rotary cam 26 is held slightly above and out of engagement with the
continuously rotating roller 36. When a delivery gate is released and is moved
rearward, as in Figure 5 its rear end strikes the depending portion 35 of the stop
dog 33, and raises it from engagement with the upwardly projecting end 29 of
the oscillator. The gate then quickly meets the forwardly projecting arm 30 of
the double armed lever corresponding to said gate, and moves rearward with the
oscillator as the upper end of the latter springs back to put the rotary cam 26
into engagement with the continuously rotating roller 36.
When a delivery gate is released and moved rearward, the hooked end of the
retaining pawl 17 bears against the lower edge of the lug 19, as in Figure 5, to
enable the gate to be subsequently moved forward and reset into engagement with
the pawl.
The surfaces of the cam and roller are finely serrated or toothed to ensure a
positive action of the parts. The roller 36 rotates the cam and thereby throws
the upper end of the oscillator forward, and the forwardly projecting arm 30 of
the double armed lever corresponding to the delivery gate to be reset acts upon the
rear end of said gate and pushes it forwards until the lug 19 on the gate is
engaged with the hooked end 18 of the pawl 17 which co-operates with said gate,
as in Figures 3 and 6. The rear edge of each gate is cut away at its lower
portion so that the arm 30 bears against the upper uncut portion of the rear
edge, Figures 5 and 6, and ensures the complete resetting of the gate. As the

page_text: upper end of the oscillator rocks forward the double armed lever of the gate which
is being moved forward maintains contact with the upper portion of the rear
edge of the gate, but the remaining double armed levers remain in their normal
position and stand directly opposite the cut away portions 37 of the rear edges
of the gates while the acting double armed lever stands in the position represented
in Figure 6, whereby the gate being acted on by the double armed lever can be
completely reset without the other double armed levers coming in contact with
the rear ends of the remaining gates before the gate being moved forward has
reached the required position to be automatically engaged by the pawl 17. When
the delivery gate is moved forwards by its double armed lever, the depending
portion 35 of the stop dog 33 is released and the dog falls into such position that
when the rotary cam has made a complete revolution, and the oscillator springs
rearward, it is arrested by the stop dog engaging the upper end 29 of the oscillator
and therefore the rotary cam cannot engage the continuously rotating roller. In
the former monoline machine, when the oscillator or bell crank lever frame is
thrown forward, it rebounds and causes the rotary cam to engage the continuously
rotating roller at an improper time and not infrequently repeated vibrations of
the oscillator result, producing an objectionable chattering, which the new con-
struction entirely avoids. In other words, in the present invention the stop dog
automatically arrests the back stroke of the oscillator after a finger key is operated
and a delivery gate has been reset, and the rotary cam at the rear of the oscillator
cannot be thrown at improper times into engagement with the continuously
rotating roller, thus avoiding objectionable chattering or rapidly repeated vibra-
tions of the oscillator incident to its rebounding when thrown forward to reset a
matrix bar delivery gate. A smoother and more uniform operation of the parts
is also obtained by the present improvement.
The release of a gate, its rearward motion, the back motion of the upper end
of the oscillator, the engagement of the cam with the cam actuating roller, and
the forward motion of the oscillator to reset the gate, are practically instantaneous,
due to the swift action of the parts.
The arresting stop dog 33 is particularly important if the lower end of the
oscillator is moved forward by the action of a spring, as hereinafter appears par-
ticularly in connection with the detailed description of the assembly box ejector.
If the lower end of the oscillator is moved forwards by a spring, it is essential
to arrest the back stroke of its upper end to prevent the oscillator cam from
engaging the cam actuated roller on the back stroke after a delivery gate has
been reset. It is to be understood, however, that as regards the oscillator and its
arresting device, the oscillator may be thrown rearward at its upper end by the
direct action of a released delivery gate, as in the former machine, and need not
necessarily be acted upon at its lower end by a spring.
In Figures 3, 5, and 6, there is exhibited a horizontal spring projected pin or
rod on the support of the oscillator, which lies in the path of a lower part of the
latter. This spring projecting pin or rod may or may not be used. When used,
it is pressed rearwards by a part of the lower end of the oscillator as the upper
end of the latter is moved forwards by the cam 20 and the roller 36, thus com-
pressing the spring of the pin or rod and cushioning the back stroke of the lower
end of the oscillator. The release of the arresting stop from engagement with the
upper end of the oscillator, permits the spring pin or rod to shoot forward with
the lower end of the oscillator as the upper end thereof moves rearward.
As will hereinafter appear in the description of the starting and stopping
mechanism, the spindle carrying the serrated or toothed roller 36, which actuates
the serrated or toothed rotary cam of the oscillator, is not geared to the driving
gear by which motion is transmitted to the main or line shaft, but on the contrary
is driven by independent means completely under control of the operator, whereby
the roller which actuates the rotary cam of the oscillator can be started and :
stopped, or controlled whenever required without regard to the driving gear.
This is advantageous in that it places the oscillator under better control of the

page_text: operator and makes it practically independent of the operation of the driving
gear which rotates the main or line shaft.
In the action of the oscillator, when the rotary cam 26 has made one complete
revolution, it is desired to stop its motion immediately after the point of greatest
diameter of the cam leaves the continuously rotating roller. This is accomplished
in a very simple manner by constructing a part of the cam shaft 25, with a
flattened portion or seat 25 against which the free end of a curved spring 25b
bears immediately after the point of the cam leaves the roller. By this means
the motion of the cam is stopped in accurate position for the subsequent engage-
ment of its lowest or point of least diameter with the roller when the upper end
of the oscillator moves rearwards.
The oscillator is connected by a link 38 with a crank arm on a rock shaft 39
journalled in the top of the magazine, Figures 1, 2, 3 and 11, and carrying
vibrators 40, one for each matrix bar chamber, for jogging or pressing the matrix
bars well down upon the inclined guide rails or wires 10 by which they are
suspended in the magazine chambers. This is much the same as in the former
machine, but the auxiliary fingers of that machine are dispensed with and the
vibrators are mounted directly on the rock shaft which is connected with the
oscillator, whereby this part of the mechanism is simplified and a more positive
action of the vibrators on the matrix bars is obtained.
THE SPACE-BAR LEVER AND FEEDER.
Instead of the somewhat complicated connections used in the former
monoline machine for lifting the space-bars, placing them in their delivery
channel of the magazine, temporarily supporting them therein and then
driving them downward into the assembly box, the following improved and
simplified means are provided for effecting the correct feed or delivery of the
space-bars into the assembly box. An elbow or bell crank space-bar
lever 41, Figure 7, is pivotted at a point near its angle as at 43, to a bracket 42
on the rear of the magazine. One arm of this lever extends over the top of the
magazine and the other arm extends down behind it and is provided near its
lower extremity with a rearwardly projecting arm 44. The vertical arm of the
lever is connected with a spring 45 by which. this lever arm is suddenly drawn
rearwards, when released from restraint, for the purpose of throwing the front
extremity of the horizontal arm of the lever downwards to drive the space-bar into
the assembly box. Near the lower extremity of the space-bar lever, at the rear
of the magazine, is pivotted a space-bar lever detaining dog or pawl 46 connected
by a rod or link 47 and levers 48 and 49, Figures 7, 8 and 9, with the lever 50" of
the space-bar key 50. The lever 4$ is pivotted between its ends, and one end is
engaged with the lever 49 while the other end is raised by a spring 48 and is
pivotted to the lower extremity of the rod or link 47. The lever 49 is pivotted
and connects with the space-bar lever 50%, substantially the same as in the former
machine.
The front end of the arm of the lever which overhangs the magazine is jointed
by a pin and slot with a vertically movable slide plate 51, Figures 7, 13, 14, 15, 18
and 19 having a lifting horn 51" and a pusher arm 51. The horn serves to lift
the space-bars, one at a time, to register their hooks with the fixed notched
retaining plate 52, and subsequently the pusher arm drives the space-bars down-
wards through the delivery channel of the space-bar chamber into the assembly
box. When the space-bar is lifted by the lifting horn to the fixed notched retain-
ing plate and is caused to enter the delivery channel, it falls a short distance and
is then arrested and temporarily supported by a friction spring 53 until the pusher
arm of the slide plate 51 descends, when the pusher arm strikes the hooked upper
end of the space-bar and drives it swiftly down into the assembly box. The
vibrating motions of the space-bar lever 41 are effected by the oscillator and by
the spring 45. A pivotted pusher 54, Figures 13, and 18 to 21, pressed forward,
or to the right by a spring 55 is situated in the top portion of the space-bar

page_text: chamber, slightly above the fixed notched retaining plate 52, and is so constructed
that when the slide plate or pusher 51 rises to lift the space-bar and permit it
to pass over the retaining plate into the delivery channel, the pusher 54 springs
and acts upon the upper end portion of the space-bar to push it quickly over the
retaining plate into the delivery channel in which it descends by gravity until
arrested and temporarily held by the friction spring 53. As the slide plate or
pusher 51 descends to drive the space-bar down the delivery channel into the
assembly box, an inclined part of the slide plate acts upon an inclined part of
the spring pressed pusher and presses it backward or to the left, so that its spring
is put under increased tension and it does not interfere with the lifting of another
space-bar.
When the space-bar lever is in the position shown in Figure 7, it is assumed
that the slide plate 51, by its lifting horn 51, has lifted a space-bar and the latter
has been placed in position to be thrust swiftly down into the assembly box when
the space key 50 is touched by the operator. When the space key is actuated
the link 47 is drawn down and the detaining dog or pawl 46, releasing the lower
end of the space-har lever, is held down by the lower end of the
lever bearing on it, and the dog or pawl cannot rise until the lower
end of the lever is properly moved forwards by the oscillator. When the dog or
pawl 46, is drawn down and releases the space-bar lever, the lower end of the latter
is snapped rearwards by the spring 45, over and against the depressed dog or pawl.
and it remains in this back position until a matrix bar key is touched to release a
delivery gate, whereupon the oscillator thrown rearward at its upper portion and
operated by the cam and roller, is swiftly moved forwards at its upper end and
resets the delivery gate. Concurrently therewith a finger 44", Figures 4 and 10,
on a top part of the oscillator, preferably on the innermost side of its upper end 29,
acts upon the projecting arm 44 of the space-bar lever to move it forwards and
reset the lever in engagement with the dog or pawl 46. After the lower end of
the space-bar lever is moved sufficiently forwards by the finger 44° the dog or
pawl, previously held down by the lever, snaps up past and engages the lower
end of the lever, this action being effected by the spring 48", Figure 8, connected
with the rocking lever 48, as before explained. The action of this spring 48°
also restores the space-bar key 50 to normal position. In the last mentioned
movements of the space-bar lever, the slide plate 51 is raised, its lifting horn 51ª
clevates or lifts a space-bar, and the pusher 54 forces the latter into the delivery
channel ready to be driven down into the assembly box by a subsequent operation
of the space key. After the space-bar key is touched and the space-bar lever is
released, the lower end of the lever remains back until a matrix bar key is operated,
thus rendering it impossible for two space-bars to be delivered and assembled
side by side without a matrix bar between them.
THE ASSEMBLY BOX AND EJECTOR DEVICES.
The matrix bars are delivered into the assembly box and are arrested by the stop
bars 56, Figures 2, 27, 29 and 30, at the proper points to place the required
intaglio characters in line, and each of the stop bars is reset or retracted by the
comb-like yoke 56 jointed to the outer end of a slide bar 57, Figures 2, 28, 29
and 30, pivotted at its inner end to a link 58 which connects with a lower end
portion of the oscillator and is operated as hereinafter set forth in detail.
The manner of arranging the intaglio characters in groups on the matrix bars,
and the means for advancing the stop bars 56, are the same as in the former
monoline machine, so that a more detailed description is not here essential, for it
is to be understood that only those parts constituting the present improvements
are herein explained in detail, as the Specification and Drawings of the former
Patent sufficiently explains those things which are not herein referred to in
detail with regard to their specific construction and mode of operation.
As before, the matrix and space-bars descend, in the order in which the matrix
keys and the space-bar key are operated, into the assembling or composing box

page_text: from which each bar as it is received therein is ejected into the longitudinal line
raceway GOb, in proper position relatively to the line carriage 60, Figures 1 and 27.
The inclined guide plate 59 Figure 27, extending in front of the magazine, at
its right, serves to accurately guide the matrix bars to a common point in the
assembling or composing box, where they are properly arrested at the correct
level by the stop bars 56°.
The assembling or composing box is arranged directly beneath the delivery
point of the several channels running at right angles to the magazine chambers,
as before stated. The box comprises the two pivoted jaws 61, Figures 27, 28, 29,
30, 32 and 33, constructed with angular bent or hooked extremities which, when
the jaws are in their closed position, close or nearly close one end of the box. The
ejector finger 62 is movable horizontally in the box and is constructed with opposite
inclines 62 to act upon inclines on the insides of the jaws 61 and spread them
apart. The ejected matrix or space bar is pushed by the ejector past a spring
detaining pawl 60%, Figures 28, 29, 34 and 35, the purpose of which is the same
as the two spring hooks of the former patent, that is to say, to prevent the
matrix and space-bars from moving backwards or to the right.
The detaining pawl 60° co-acts with the line abutment to hold the line as it
is being assembled. This pawl differs from the former detaining hooks in that
it is a single plate having a broad faced engaging hook exactly vertical to afford
an extended base of support which aids in maintaining the matrix bars perpen-
dicular. The body of this pawl lies in a recess in the face plate below the
magazine and its engaging bevelled hook or nose is normally pressed outward by
springs through a vertical slot in said face plate into the path of the matrix bars
ejected from the assembly box.
The ejector is operated by improved and simplified mechanism. It is loosely
ngaged directly with one arm of a bell crank lever 63, best seen in Figure 28,
which enters a recess or socket in the ejector, the other arm of the lever being
pivoted directly to a bar or rod 64 extending back and provided at its rear end
with a slot to engage loosely a lower end portion of the oscillator, as for instance
the cross pin 59. The bell crank lever 3 is pivoted at its angle to a vertical pivot
pin to vibrate in a horizontal plane, and the bar or rod 64 is connected with one
end of a spring 65 having its other end attached to a lug on the bed plate of the
machine.
The link 58, which extends from the slide bar 57, of the yoke 56, is provided
at its rear end with a slot of a length slightly greater than the slot in the rear end
of the bar or rod 64, as shown in Figures 28 and 30. The cross pin 59, or a
similar part at the lower end of the oscillator, passes through the slots in the
bar or rod and the link, all in such manner that when the upper end portion of the
Oscillator moves forward to reset a delivery gate, its lower end portion moves rear-
wards and the cross pin 59 acts first against the rear end of the slot in the bar or
rod 64 to swing the bell crank lever in the direction necessary to advance the
ejector and eject the matrix bar from the assembly box, it being understood that
the actuation of a key of the keyboard has shifted the required stop bar into
position to arrest the matrix bar at the proper level to place the desired intaglio
character in the line being composed. The back motion of the lower end of the
oscillator also causes the cross pin 59 to act on the rear end of the slot in the
link 58 slightly after the cross piece has acted to move the bar or rod 64 slightly
rearward, whereby the slide bar 57 and the yoke 56 are shifted rearward to reset
or push back the projected stop bar immediately after the matrix bar is ejected
from the assembly box and the ejector is being retracted to normal position.
When the upper end of the oscillator moves rearwards and the lower end moves
forwards the spring 65 serves to hold the rear end of the slot in the bar or rod 64
firmly against the cross pin or piece 59 at the lower end of the oscillator, so that
when the rod or bar stops, as it does when the ejector strikes the right hand end
of the assembly box, the cross pin can move forward in the slot of the link 5S

page_text: and act against the forward end of said slot to move or push forward the yoke 56
for a subsequent back motion to reset a stop bar.
The two jaws of the assembly box are spanned by a yoke shaped bar 66, having
its ends extended downwards to form shoulders 67. These shoulders contain
chambers containing springs 68, Figure 33, which act to close the two jaws of
the assembly box after they have been opened or spread apart by the ejector and
the latter is retracted. The shoulders of the yoke shaped bar serve as stops to
limit the opening movement or spreading apart of the two jaws of the assembly
box.
The first matrix bar of a line being composed, after it is ejected from the
assembly box past the detaining pawl 60 bears against a yielding line abutment
connected with a slide block or carriage which is restored to normal position after
a line is composed and moves towards the justifier, as will now be explained.
THE LINE ABUTMENT AND ITS CARRIAGE.
In the former machine, a part of the holder for the line being composed consists
of a slide block which carries two fingers constituting a travelling line abutment
for one end of the line, the fingers being tripped at a predetermined time as the
assembled line is carried by the line carriage to the justifier to permit the fingers
to be forced inward and with the slide block to resume normal position preparatory
to composing a new line. This slide block carries a spring pressed pawl co-
operating with a rack, and is otherwise provided with more or less complicated
or intricate devices which have been materially improved and simplified. The
new line abutment is composed of a solid head 69" having two arms or members
extending substantially at right angles from it and constituting a duplex finger 69.
The solid head is pivoted, as at 69b, to a carriage or slide block 70 moving in
suitable horizontal guides on the inner side of the perpendicular face or front
plate lying below the magazine. The two arms or members constituting the
duplex finger project through horizontal slots 70, Figure 29, in the face plate,
and the upper and lower acting faces of said finger, against which the end of
the line bears, are exactly co-incident in a vertical plane. The head 69" is acted
on by a spring 1 which throws the duplex finger outward when it is not held by
a locking dog 72. This locking dog is pivoted to the carriage or slide block at
a point in rear of the pivot of the head 69", and when the duplex finger is
projected through the slots in the face plate to form an abutment for one end of
the line being composed, the notched extremity 73 of the dog engages the angle 74
of the duplex finger and its head to hold the said finger rigidly projected. The
notched end of the locking dog is positively forced into engagement with the
angle 74 by a spring pressed pin 75 mounted in the carriage or slide block 70.
The carriage or slide block 70 is pivottally connected by a link 76 with the outer
end of a horizontal vibratory lever 77, mounted at its rear end on a stud 78, rising
from the bed plate around which is coiled a spring 79 engaged with the lever in
such manner that as the latter is forced to the left the power or tension of the
spring is increased.
After the line of matrices is composed and this line is in charge of the line
carriage, as the latter moves to the justifier the line abutment is carried along
until the locking dog 72 strikes a fixed stop bracket 80, that trips the dog and
releases the line abutment, which is then forced inward by the moving composed
line, after which the carriage or slide block 70, carrying the line abutment, is
restored to normal position by the action of the spring 79 forcing the lever 77
towards the right hand end of the machine. When the tail end of the locking
dog 72 leaves the stop bracket 80, and the composed line has passed the line
abutment the latter is thrown outward by the spring 71 and the spring pressed
pin 75 forces the locking dog 72 into engagement with the angle 74 of the line
abutment to hold it rigidly projected.
The vibratory lever 77 carries a pivotted bell hammer or striker 81 designed
to strike a bell or gong 82 suitably supported over the pivoted end of the lever.

page_text: The bell hammer or striker 81 is provided at its pivoted end with a tail piece on
which a trip pawl 83 is so pivoted that when the line is nearly of the proper length
the trip pawl strikes a lug 84 and thus swings the bell hammer away from the
bell and against the tension of a spring 85 connected with the bell hammer. The
continued motion of the vibratory lever 77 to the left causes the pawl 83 to trip
past the lug 84 and then the bell or gong is instantly sounded by the bell
hammer 81 indicating to the operator that the line is approximately of the proper
length. When the vibratory fever 77 moves to the right to restore the line abut-
ment to normal position, the trip pawl 83, by its pivotal mounting and inclined
face, easily rides past the lug 84, as is obvious. The lug 84 is shown mounted
upon an adjustable arm St arranged at its inner end on the same axis as the
vibratory lever 77, the purpose being to adjust the lug 84 relatively to the trip
pawl of the hell hammer to suit the conditions required when lines of greater or
less length are desired, as for instance where the line carriage is made adjustable
to compose a line of greater or less length. The tension of the coiled spring 79
can be varied by means of the notched disc 87 and the locking pawl SS.
THE LINE CARRIAGE.
The line carriage 60, best seen in Figures 23 to 27, is similar to that
employed in the former machine, and is moved longitudinally on the horizontal
guide bar or rail 89, by means of the line carriage lever 90, Figures 1
and 2, which is actuated by a cam 91 on the main line shaft 92. The line
carriage lever is pivoted below the bed plate, as at 93, and comprises two sections
jointed together at 94, one part having its front end engaged with the line carriage
and curved outwardly at its rear where it is connected by a pull spring 95 with
the rear section of the lever. As the cam 91 has considerable overthrow motion,
the rear section of the line carriage lever can yield if the front section comes to
rest, and the line carriage can be very firmly pressed into the anvil under the
tension of the spring 95, without regard to the length of the line.
The latch, trip pawl and lug on the radial arm H8, for locking and releasing
the swinging wing of the line carriage which were used in the former machine,
are now dispensed with, and the means for locking and unlocking the wing, are
materially simplified and improved as will now be explained. The wing 96
swings vertically on the guide rod 97 into and out of the line raceway and is
locked in position after being swung upwards against the rear or right hand end
of the composed line of matrices by means of a horizontal locking bolt 98 housed
in the body of the line carriage and projected by the action of a spring 99 which
bears against the inner end of the bolt. The wing is raised against the tension of
the spring 100, when the desired line is composed, by the radial lever 101 and
lever 102, as in the former machine. When the wing is raised to the proper
position the spring locking bolt 98 snaps into a bolt hole or orifice 103 in the
wing, thus locking the wing until the line has been shifted to the justifier and
the casting mechanism and is making its return stroke, when it becomes essential
to unlock the wing so that it will be automatically thrown down by the spring 100
out of the path of another line being composed by the operator, for enabling the
line carriage to pass to normal position for a subsequent raising and locking of
the wing and shifting of the carriage. To accomplish this automatic release of
the wing, the locking bolt 98 is recessed to receive the rounded lower end of a
bolt unlocking lever 104 pivoted between its ends as at 105 to the carriage body
and having its upper end arranged in the path of a lever operating device or pro-
jection 106, Figures 1 and 27, on the movable aligning bar or rail 107. The
upper end of the lever passes the device 106 when the aligning bar is advanced and
the line carriage is shifted to the left, as is necessary to move it to the justifying
and casting mechanisms, but is acted upon by said device when the aligning bar
is retracted and the carriage moves back to normal position, thus causing the
locking bolt to release the wing, whereupon the spring 100 throws the latter down-
ward out of the line raceway and permits the carriage to move into normal position

page_text: to take charge of the new line being composed by the operator. The jaw or
Jug 108, Figure 27, which co-operates with the wing 96 to carry the line, is sleeved
at its upper end on the guide rail or rod 97, and at its lower end on the shaft 110,
which extends into the line carriage body where the ratchet hub 109 and ratchet
sleeves 110, Figure 26, are arranged, as in the former patent, in such manner
that when the crank arm 111, on the shaft 110 is raised, the jaw or lug 108 is
caused to move to the left, or away from the wing 96, that is to say the line
carriage is expanded to loosen the line of matrices and facilitate the depression
of the matrix bars, after the casting operation, as in the former Monoline
machine. The crank arm 111 is raised at the casting point, after a printing bar
has been cast, by means of the slide 112, having slots through which headed
pins 113 pass into the body of the line carriage. The slide 112 is provided at its
left side with a roller stud 114 which at the proper time is acted on by the incline
or wedge shaped outer end 115 of the transverse sliding bar 116, Figures 36, 60
and 61, to obtain a primary or first release of the line and enable the depressor 117
(after the movable aligning bar 107 is retracted, as in the former machine), to
depress the matrix bars to a level at their lower ends, and push down the upper
ends of the lower expander scetions of the space-lars to restore the latter to
normal length. The transverse sliding bar 116 is pivotted at its inner end directly
to an arm 118, Figures 60 and 61, rigidly projecting from the auxiliary shaft 119,
which latter is like that in the former machine. The auxiliary shaft is provided
with a radial arm 120, Figure 59, connected by a link 121 with an elbow or bell
crank lever 122 actuated by the cam 123 on the main shaft, to rock the auxiliary
shaft at the proper time.
THE SECOND LINE RELEASE.
As before explained, the line of matrices is released at the casting point
for the purpose of enabling the matrix bars to be depressed for placing their
lower ends on the same level and to push down the upper ends of the
lower expander sections of the space-bars. A second release of the line is
advisable at the distributor, that is to say where the matrix and space-bars are
strung upon the distributing rods or wires hereinafter referred to, in order to
facilitate the lifting of the matrix and space-bars out of the line carriage when
the distributing wires rise. To secure this second release of the line the front of
the machine to the left of the key board, instead of being open, as in the former
Monoline machine, is closed by a solid metal panel or plate 124, Figures 27 and 8,
on which is pivoted at 125, a gravitating ilog 126, placed centrally below the
distributor, and constructed at its outer edge with a lateral bevel or incline 127,
which, as the line carriage moves back to the distributor, acts upon a roller
stud 128. Figure 24, extending from the inner side of the slide 112, to raise the
slide and elevate the crank arm 111. The crank arm, through the shaft 110 and
the ratchet hub and sleeves before mentioned, and disclosed in the former patent,
causes the carriage to expand or spread and release the line for enabling the
matrix and space-bars to be easily Efted out of the line carriage. The gravitating
dog 126 is held against swinging to the right or towards the key-board, but is
free to swing to the left or towards the casting mechanism, and, therefore, as the
line carriage travels to the casting mechanism, the roller stud 128 rides
under the level or incline 127 of the dog and lifts the latter out of the path
of the stud. After the stud passes the dog the latter gravitates to normal position
and operates upon the stud 128 to raise the slide 112 on the return stroke of the
carriage, as above explained.
THE PRIMARY LINE DEPRESSOR.
The primary line depressor 117, best seen in Figure 36, comprises a broad metal
plate mounted on the upper end of the skeleton sliding frame 129 which moves
in vertical guides and at its lower end is connected by a link 130, Fig. 59,
with the outer end of a curved lever 131 pivoted at 132 to a bracket arm

page_text: extending from the front plate or panel of the machine. The lever 131. is
provided with a tail piece 133, in rear of the pivot, connected by a slotted
Link 134 with an armi 135 rigidly secured to the auxiliary shaft 119, the con-
struction being such that the depressor is raised and lowered by the rocking
of the auxiliary shaft. The auxiliary shaft, as in the former machine, operates
the transverse sliding bar 116, to release the line, retracts the aligning bar 107
in the anvil 136, and draws down the depressor 117. The devices for retracting
the movable aligning bar are located in the anvil, Figs. 1 and 36, and are operated
by the vertical shaft 137, crank 187ª and rod 138 connected with the auxiliary
shaft.
The upper end of the vertical shaft 137 is engaged by an eccentric pin with a
slot in the left hand extremity of the movable aligning bar or rail 107, and when
the shaft is turned the bar or rail is moved longitudinally by oblique slots and pins
and is advanced or retracted at the proper intervals according to the direction in
which the shaft is turned by its connection with the auxiliary shaft.
SAFETY OR SECONDARY LINE DEPRESSOR.
To insure the correct depression of all the matrix bars, if from any cause one or
more should not be accurately levelled after the printing bar has been east, the
primary line depressor 117, is depressed and the line is being moved by the line
carriage 60 back to the distributor, hereinafter described, there is provided a
safety or secondary depressor 159, Figs. 37, 86, 41, 43 and 45, composed of a broad
plate of metal attached to the mold carrying frame 160 and having a bevelled
underside to act upon the flat upper portions of the matrix bars to level any one
or more that may possibly not be properly level as the line is moved from the
casting point to the distributor. The object of this is to place with certainty all
the matrix bars in exact alignment at their lower ends, which is important to
secure the correct position of their hooks and their accurate stringing on the
distributing wires of the distributor. This safety or secondary depressor is fixed
to the end portion of the mold carrying frame opposite the pivoted end of the latter
and is projected and retracted as will hereinafter appear in connection with the
description of the operation of the mold, the mold carrying frame, and the casting
pot.
THE JUSTIFIER.
The justifying mechanism by which the space-bars are operated to expand the
line to exact length, is constructed and operates substantially the same as in the
former Monoline machine and comprises a shoe 139. Figs. 37 and 36, secured to a
base plate 140 movable vertically between the guide legs 141 and 142 and con-
nected as before, with a spring yielding link 145, Fig. 2. attached to a pivoted
lever 146 engaged with and operated at the required intervals by the cam 147 on
the main shaft.
The overchanging or raised flange 139°, Fig. 27 on the fixed aligning bar or
rail 139, to extend over the usual lugs on the space-bars at the justifying point,
is at the left hand end braced by a perpendicular brace-post 139° so that the
flange can successfully resist all strains and upward pressure exerted on the space
bars.
In operative connection with this justifier there is provided mechanism for
operating a loose line signal and a pot cut off, which latter prevents the flow of
metal to the mold if a line of matrix and space bars should be loose, that is to say
of such length that the upward motion of the movable parts of the space bars
will not properly expand the line and the justifying shoe unduly rises, which is
permitted by the spring link 145. When this occurs the signal and pot cut off
are operated, as will be hereinafter explained.
THE CASTING POT, MOLD AND MOLD FRAME.

page_text: surrounding jack 148 entirely open at its lower end, and the bottom wall of the
well, in which the plunger operates, and also a portion of the lower side of the
metal delivery channel or throat leading to the mold, are exposed to the direct
action of the heating medium, such as the flame of a gas burner, in consequence
of which the metal at the bottom of the well and in the lower portion of the delivery
channel or throat lying inside the pot is heated to a higher degree than the remain-
ing metal in the pot and well. To avoid this disproportionate and overheating
of the metal in the well and a part of the delivery channel or throat, the well 149,
Fig. 40, is submerged in the pot 150 in such manner that the well is suspended
with its bottom wall elevated above the bottom wall of the pot, so that a body of
molten metal lies in the pot between its bottom and the bottom wall of the well,
by which means the bulk of metal in the pot and that in the well and delivery
channel or throat are sustained approximately at the same temperature and there-
fore the metal which flows into the mold to produce the printing bars is always
of a uniform temperature, by which better castings are obtained and the best
results are secured.
The casting pot is constructed with flanges at ats its top. Fig. 41, which rest on the
upper edge of the pot jacket 148 and by set bolts 150, carried by the jacket, the
pot is adjustable in two planes at right angles to each other, to accurately place
it to suit whatever conditions may be required. The jacket is supported at its
front by roller bearings 150 to facilitate its to and fro sliding motions.
The plunger of the pot is operated in the usual manner by a cam 151, Fig. 1, on
the main shaft acting on a lever 152, which after being raised by the cam is quickly
drawn down by a spring 153, as is well known. The cam 154 on the main shaft
serves to move the pot to and fro, and for this purpose the cam is constructed at
its sides, as in the former machine, to engage anti-friction rollers on the ends of
the arms 155 extending back from the pot jacket. The pot operating cam 154
is constructed with two acting surfaces 156 and 157, one of which acts on the
roller 158, to move the pot to and against the mold, for locking up the line and
casting the printing bar, while the other acting surface acts to subsequently
advance the pot and press forward the mold carrying frame 140 for the purpose
of placing the safety depressor 159, Figs. 37, 36, 41, 43, and 45 before referred
to, in proper position to insure levelling of the matrix bars as the line is moved
by the line carriage back towards the distributor. The safety depressor, as before
stated, is composed of a broad, flattened piece of metal having a beveled under-side.
This piece of metal is rigidly secured to the mold carrying frame 160, which is
pivoted at one end, as at 160, as in the former machine. Instead, however, of
this frame being moved to and fro by a set of levers and a cam on the main shaft,
as before, it is according to the present invention moved to and fro by a direct
connection with the casting pot. To secure this result, the casting pot is provided
at one side with a projection 161, Figs. 41 and 43, to which is secured an arm 162.
The end of the mold carrying frame opposite its pivotted end 160" is provided
with a bracket 164 pivotally connected with the arm 162 by a link 165. Thus as
the pot is moved to and fro the mold carrying frame is correspondingly moved to
and fro by very simple devices.
The right hand end of the mold carrying frame is constructed with a guide
notch, Fig. 45, movable in engagement with a fixed guide flange 160, for guiding
The safety depressor 159, before
and steadying the motions of the said frame.
referred to, secured to the mold carrying frame near the end opposite its pivoted
end, is moved forward, each time the mold carrying frame is advanced by the
casting pot. This depressor passes through an orifice in a front part of the
machine and can project some distance froin it. When the pot advances to lock
up the line of matrices and effect the casting of the printing bar, the safety de-
pressor performs no fuction, but on the second forward stroke of the casting pot
The safety depressor, being projected lies in such position that as the depressed
line of matrices is moved by the line carriage towards the distributor, the safety
depressor presses down any of the matrix bars that are not properly leveled or

page_text: pressed down into correct position for stringing upon the distributing wires of
the matrix bar distributor, bereinafter explained.
The arms 155 of the pot jacket move to and fro on anti-friction rollers 155ª,
and the shaft 158" of the roller 158, passes through slots in the arms 155, Fig. 41
and is carried by arms 155b, Fig. 41, engaging the pot jacket and made adjustable
for moving the shaft to adjust the roller 15S relatively to the acting surfaces of
the pot moving-cam on the line shaft. The arms 155b are made adjustable by
suitable screw threads on them.
As here shewn, the pot jacket moves to and fro on roller bearings and the
roller 158 between the pot arms is provided internally with roller bearings for
the purpose of obtaining a smooth working of the parts. The mold 166 Fig. 50,
is movable longitudinally in a slot in the mold carrying frame 160, but it is
operated by the improved and simplified means hereinafter explained. When
the pot moves up to the mold after the line of matrices has been placed by the
line carriage in proper relation to the mold, the forward thrust or pressure of the
pot upon the mold forces all the parts closely together. locks them up and tightly
clamps the line between the mold and the anvil 136 which latter, as in the former
machine, is made strong and substantial so as to resist all pressures and strains.
When the parts are clamped, as above stated, the plunger of the well in the pot
is operated to inject the metal into the mold, after which the pot cam retracts
the pot, the mold carrying frame and mold are drawn back to withdraw the cast-
ing from the matrices, the mold moves to the ejector, and immediately the pot cam
again moves the pot forward to advance the mold carrying frame parallel with
the trimming knives and to thrust forward the safety depressor 159 for ensuring
the levelling of the previously depressed matrix bars. The frame 160, carries a
back trimming knife 1604, Figs. 1, 45 and 50, to remove surplus metal from the
bases of the castings as the mold moves to the ejector.
THE MOLD SHIFTING DEVICES.
The mold 166, Fig. 50 is shifted to and fro in the slot of the mold carrying
frame to convey the printing har from the casting point to an ejector blade 167,
Fig. 1, reciprocated at the proper interval by the cam 168, on the main shaft, by
which the printing bar lying in the mold is ejected between the trimming
knives 169 for dressing or smoothing its sides. Instead, however, of employing
a system of levers and toothed sectors underlying the bed plate of the machine,
to shift the mold, as in the former machine, this is now effected through the
medium of a single lever 170. Figs. 1, 46, 49 and 50, which overlies the bed plate
of the machine and is pivotted to it between the ends by a vertical pivot as at 171.
The pivot of the leaver is near the main shaft, and the lever possesses a long
and a short arm. The short arm is provided with a roller stud 172 engaging
the lever operating cam 171-similar to that in the former machine. The outer
extremity of the long arm of the lever is pivotted to one end of a link 174 jointed
at the other extremity to a part of the mold so that when the lever is vibrated
in a horizontal plane the mold is shifted to and fro.
THE TRIMMER WIPER.
In the practicable use of the Monoline composing machine simple means are
desired for cleaning the trimming knives as the mold moves in its carrying frame.
without however sweeping the trimmings from the knives in opposite directions.
To accomplish this, the outer end portion of the mold shifting lever 170 is pro-
vided with an upright post or stud 175, Fig. 46, which enters a somewhat en-
larged rectangular opening 176. Fig. 49, in a flattened plate 177 attached to and
projecting back from a wiper carrier or slide 178. Figs. 46, 47, 48 and 49, sleeved
upon and travelling lengthwise of a guide rail 179 secured at its ends in lugs
rising from the top edge of the mold carrying frame. The wiper carrier or slide
is provided at its front with a horizontal stud 180 on which is pivotted a pendent
arm 181 having its lower end portion provided with a flexible wiper 182. This

page_text: When the
wiper may be of any construction and of any material suitable for the purpose,
that is to say, for cleaning the trimming knives after each printing bar has been
ejected between them. The pivotted wiper arm 181 is provided at its upper end
with a tail piece connected with one end of a spring 183 which at the other end
is attached to the wiper carrier or slide 178, the spring serving to force the wiper
arm to a perpendicular position, as shown in full lines, Fig. 47.
wiper arm is perpendicular or approximately so, and is making its wiping stroke,
it is held or supported by a stop lug 184 on the wiper carrier or slide. The wiper
arm is provided with a leaf spring 185 secured at its upper end by a screw or
otherwise, as at 186, and provided at its lower end with a lateral pin 187 which
freely passes through an orifice in the wiper arm and normally projects beyond
its rear surface to travel upon the upper edge of a horizontal guide strip 188
attached to the mold carrying frame above the slot in which the mold is shifted
to and fro. The guide strip 188 is provided at one end, that is to say, the end
nearest the pivotted end of the mold carrying frame, with an incline 189 extend-
ing to and merging in the horizontal top edge of the guide strip. The end portion
of the guide strip having the incline is constructed at a point opposite the incline
with a beveled portion 190 designed to act upon and press outward the pin 187.
as will hereinafter appear. In the normal position of the mold operating lever,
the wiper arm 181 stands substantially perpendicular as shown by full lines.
Fig. 47, and when the mold is shifted from the trimming knives to the easting
pot, the pin 187 on the lower end of the leaf spring rides up the incline 189 of
the guide strip 188. As the wiper carrier or slide follows the motion of the mold
the wiper arm is held in an inclined position by the pin 187 resting against and
travelling upon the upper edge of the guide strip, whereby the wiper 182, is held
above the trimming knives and does not act upon the same as the wiper travels
towards the casting pot. The pin 187 however eventually rides off the guide
strip, whereupon the spring 183 swings the wiper arm to the perpendicular posi-
tion indicated in dotted lines, Fig. 47. On the return stroke of the wiper, or
when the mold is moved from the casting pot to the trimming knives 19 for the
ejectment of a cast printing bar, the wiper sweeps over the edges of the knives
and sweeps off all trimmings in a direction towards the left hand end of the
machine. Thus the wiper sweeps trimmings from the knives only in one direc-
tion and the accumulation of trimmings at hoth ends of the knives is thereby
avoided. In order to enable the mold to travel a slightly greater distance towards
the casting pot than the wiper carrier or slide travels, when the mold shifting
lever swings towards the casting point, the enlarged opening 176 in the plate 177,
is provided. When the mold shifting lever begins to move it can move a limited
distance in the opening 176 before motion is imparted to the wiper carrier or slide,
and, therefore, the mold begins to move before the wiper, which enables the guide
rail 179 to be shortened and not necessarily to be made of a length co-extensive
with the extent of movement of the mold. The enlarged opening 176 also
enables the wiper carrier or slide 178 to move in a rectilinear path on the guide
rail 179 while the outer extremity of the shifting lever travels in the are of a
circle. In the operation of the mold, as the justifying shoe 1339 rises, the mold
shifting lever begins to swing, and the mold to slide in a direction from the
trimming knives to the casting pot. The wiper carrier or slide begins to move
slightly after, as it does not require to move the same distance as the mold. The
mold moves to the pot, and the line carriage moves to the mold where the printing
har is cast. The mold then makes the back stroke while the line carriage
remains motionless and the line is released to be depressed by the primary
depressor 117.
TTIME

page_text: correct action.
This is avoided by the present invention and a novel simple and
efficient galley is provided which can be readily removed and replaced and wherein
the printing bars are accumulated in a horizontal column. The galley is best
shewn in Figs. 1, 36, 57 and 58 and comprises a rectangular box like receptacle 191
the rear wall of which is somewhat higher than the front wall so that while the
basis of the printing bars are squarely supported by a solid wall the upper end
portions of the edges, bearing the relief characters are exposed. The galley box
is mounted on a horizontal bracket or shelf 192 projecting from the front of the
machine and having at its lower side a leaf spring 193 attached at one end and
provided near the opposite end with a locking pin 194 extending upward
through an orifice in the bracket or shelf and entering a pin hole in the base of
the galley box whereby the latter is locked in partition but can be readily removed by
pressing down on the leaf spring to disengage the locking pin from the galley box.
The galley box contains a sliding abutment or block 195 for one end of the column of
accumulating printing bars. The base of the abutment or slide block is provided
with a friction spring 196 pressing against the bottom of the galley box for
retarding to a certain extent the free sliding motion of the abutment or block
and preventing it from moving too far when a printing bar is introduced into the
column being so accumulated. The bracket or shelf 192 is provided at its lower
portion with a bearing 197 in which is mounted a short rock shaft 198 having at
its outer end an attached upwardly projecting finger 199 rising through and
vibrating at intervals in slots in the bracket or shelf and the bottom of the galley
box. To the inner end of the rock shaft is attached a rigid tappet arm 200
extending upwardly to a point directly in front of the mold carrying frame.
The upper extremity of the arm 200 lies in the path of a tappet dog 201 pivotted
to the sliding mold and having a tail piece 202 which normally rests against a
pin so that, while the dog is free to swing to the left, it is held, when sub-
stantially perpendicular, against moving to the right by means of the pin.
When the mold is shifted from the trimming knives to the casting pot the dog 201
rides over the upper end of the tappet arm, but on the return of the mold back
to the trimming knives the dog 201 strikes the upper extremity of the tappet arm
and as the dog is now held rigid the tappet arm is swung towards the left and
the vibrating finger 199 correspondendingly swung to push the column of accumu-
lating printing bars longitudinally of the galley box for making room for another
printing bar after the vibrating finger has been restored to normal position which
is preferably effected by suitable spring 20%.
THE DISTRIBUTOR.
In the former Monoline Composing Machines one set of swinging distributor
levers which carry the horizontal distributing rods or wires are pivotted at their
tail ends to slide blocks which accurately fit and work in horizontal grooves
formed in a vertically moveable slide bar. This construction is such that there
is no possibility of a release and loose play of the levers during the rising and
falling motions between their highest and lowest positions. In consequence
of this the horizontal distributing wires which are one above another when
lowered are liable to unduly clamp or press upon the hooked ends of the matrix
bars strung upon the wires immediately after the latter begin to rise. The effect
of this is that the matrix bars are more or less rigidly held at their hooked
ends and sometimes they are thus caused to stand more or less out of per-
pendicularity until the distributing wires begin to separate and spread into an
approximately horizontal plane. Under such conditions the matrix bars when
suddenly released from the holding effect of the distributing wires oscillate or
swing to and fro relatively to the front of the machine, with the result sometimes
that owing to the oscillating or swinging motions of the suspended bars they are
not pushed into the magazine chambers by the distributor pusher which forms
a part of the distributing mechanism, but strike the edges of the partitions of
the magazine chambers and perhaps fall to the bed plate of the machine this

page_text: interrupting the work of the operator and causing the loss of more or less time.
To entirely avoid this interruption to the operator which although it may not be
frequent is vexatious when it occurs devices are provided whereby the distributing
rods or wires after they rise a short distance from their lowest position do not
bear firmly against the hooked ends of the matrix bars strung thereupon but are
slightly released and susceptible of a limited play or loose motion in contra-
distinction to being held substantially rigid relative to one another until they
reach the point where they begin to separate and spread into an approximately
horizontal plane. The object of this release and play or loose motion is to avoid
the gripping or holding of the hooked ends of the matrix bars by the distributing
wires, so that the bars are always suspended perpendicularly, and do not unduly
oscillate and swing to and fro as the distributing wires rise to and reach their
highest position. Therefore when the distributor pusher operates instead of acting
upon oscillating or swinging matrix bars it encounters these bars while they are
motionless or practically so.
The result above stated is accomplished in the manner which will now be
specifically described.
The distributing mechanism is situated as in the former machine between the
justifier and the casting mechanism and the distributor is so operated that it
meets the line of matrix and space-bars as the line is carried back by the line
carriage. The distributing wires 204, best seen in Fig. 37 are suspended respec-
tively from the outer ends of carrying levers 205 and there are nine distributing
wires and nine pairs of levers the same as in the former machine one distributing
wire receiving the space-bars and the others the eight species of matrix bars.
The pairs of levers are mounted upon horizontal shafts 206 arranged in suitable
bearings rising from the bed plate of the machine. The shafts are mounted
one upon another in approximately the manner represented in Fig. 37 to obtain
the correct throw so that the pairs of levers are lowered at their outer ends the
distributing wires correctly overhang the line raceway and are arranged one
above another in an approximately perpendicular plane at one side, are provided
with arms or tail pieces 207 having lateral roller studs 216 which with
one exception hereafter stated co-operate with lever release blocks 208 fixed in
horizontal grooves in the vertically moveable slide bar 209. This bar has at
its end an arm 210 connected by a spring link 211 with a lever 212 having a
roller engaged with a cam 213 as indicated by dotted lines for the purpose of
raising and lowering the slide bar and thereby swinging the distributor levers in the
are of a circle. When they are lowered and the slide bar is depressed the levers
are raised and arrested at the exact point by a stop plate 205 Figs. 1, 38 and 39
to place the distributing wires in correct position for distribution of the matrix
and space-bars. When the levers are elevated and the slide bar is raised the
levers are lowered and the distributing wires placed one above another in correct
relation to the line raceway as in the former machine. The lever releasing blocks
are cut away at their lower sides for a portion of their length to provide hori-
zontal acting surfaces 214 and release surfaces 215 the latter being formed in
such manner that they are each at a slightly higher elevation than the horizontal
acting surface leading thereto these cut away surfaces 215 serve to slightly
release the tail ends of the levers as will hereinafter appear. The horizontal
acting surfaces 214 are parallel with horizontal acting surfaces 217 forming fixed
parts of the slide bar the construction being such that as the slide bar descends
to raise the distributing wires 204 from their lowest to their highest position the
roller studs ride off the horizontal acting surfaces 214 or on to the cut away
release surfaces 215. At this time instead of the tail ends of the distributing
levers being held in fixed relation to the slide blocks as in the former machine
the distributor levers are. susceptible of a certain amount of play or loose motion
and likewise the distributing wires which receive the matrix bars have a loose
play relatively to one another which prevents them from clamping clipping or
pressing upon the hooked upper ends of the matrix bars strung upon them. By

page_text: this means the oscillating or swinging motions of the matrix bars herein before
referred to as produced by the clamping or gripping action of the distributing
wires as they rise to the distributor pusher are practically avoided and conse-
quently when the distributor pusher plate 218 Figs. 38 and 39 moves to the right
to push the matrix and space-bars from the distributing wires the bars do not
strike the edges of the magazine partitions but glide smoothly into their proper
chambers in the magazine. The release of the tail ends of the distributor levers
by reason of the roller studs 216 riding on to the release surfaces 215 occurs,
immediately after the distributing wires begin to rise.
The two uppermost distributor levers carry the distributing wire which is the
highest one when all the distributing wires are lowered to stand in an approxi-
mately perpendicular plane over the line raceway and it receives all the space-
bars. The tail end of the uppermost distributing lever is or may be pivoted to a
slide block the same as in the former patent. The release of the tail ends of the
distributor levers occurs only when the distributing wires are between their
highest and lowest positions in both of which positions the levers are held or locked
as regards the loose motion referred to as it is advisable to maintain the hori-
zontal distributing wires motionless and steady when the matrix and space bars are
strung on them and pushed from them.
The distributor pusher plate 218 Figs. 38 and 39 is attached to two horizontal
guide rods 219 moveable longitudinally of the machine in sleeved bearings 220
supported in an elevated position so that when the distributing wires are elevated
the pusher plate when advanced pushes the matrix and space-bars from said wires.
The two guide rods are connected together by a cross head to which is pivoted one
end of a link 221 having its other end pivoted to the upper extremity of a lever
arm 222 rising from and secured to a rock shaft 223 journaled in suitable bearings
under the bed plate the lever projecting through and working in a slot in the
latter. The rock shaft is provided at one end with a crank arm 224 having a
roller stud 225 engaging a cam 226 on the main shaft in such manner that at
the required intervals the shaft 223 is rocked to swing the lever 222 and advance
the pusher plate 218 in the direction necessary to push the matrix and space
bars from the distributing wires into their respective magazine chambers. The
top edge of the pusher plate is stepped to provide pusher fingers 227 which pass
respectively beside the distributing wires and remove the matrix and space-bars
therefrom. The cam 226 and connections which actuate the distributor pusher
are so properly timed in their movements relatively to the motions of the
distributor levers that before the distributing wires start to descend the pusher
plate is retracted to normal position for a subsequent movement.
THE RECASTING MECHANISM.
It is considered advisable and advantageous to provide the Monoline Composing
Machine with mechanism whereby any desired number of printing bars can be
cast from one and the same line of assembled matrices while the line remains
motionless at the casting point. To accomplish this the motions of the justifying
mechanism the line carriage the distributor the distributor pusher the vertically
the line releasing
moveable depressor the moveable aligning bar and
devices situated at the casting point should be discontinued when the
line is at the casting point. For this purpose the cams, which operate
distributor pusher,
the line carriage, the justifier. the distributor, the
or
main line
release, the
the first
the
main line depressor, and
moveable aligning bar, are fixed to a sleeve 228 Figs. 1, 51 and 52 adapted to
rotate on or with the main or line shaft. In a portion of the cam sleeve is arranged
a longitudinally sliding locking bar 229 constructed at one end to enter a notch 230
formed in a collar 231 rigidly fixed to the line shaft near one end of the sleeve. This
locking bar is projected or pressed outward by a spring 232 to automatically engage
the notch in the collar. While the locking har is engaged with the collar the
machine operates in the usual manner and casts a single printing bar from each

page_text: line of matrices presented to the casting mechanism, but for recasting purposes
this locking bar can be thrown out of engagement with the notch in the collar by
a bevel or incline 233 formed on the arm 234 of an elbow or bell crank lever which
is pivoted at its angle as at 235 to a support in rear of the sleeve. The arm 234
of the bell crank lever is curved to extend in a direction around the rigid collar
while the other arm 236 of the lever extends upwardly and is pivoted to the rear
extremity of a rod 237 Figs. 1, 53 and 54 extending over the machine to the front
thereof and having a suitable handle within convenient reach of the operator.
The recasting rod 237 is normally pushed rearward, and the curved arm 234 having
the incline 33 is, therefore normally lifted out of the path of the locking bars 229.
to enable the cam sleeve to rotate with the main shaft during which the usual
operation of the machine takes place that is to say a single printing bar is cast
from or by each line of matrice. To release the locking bars 229 from the notched
collar 230 for the purpose of recasting any desired number of printing bars from a
line of matrices, the recasting rod 237 is drawn outward by the operator and the
curved arm 234 of the bell crank lever is thrown downward to rest upon the peri-
phery of the rigid collar 231 thereby placing the bevel or incline 233 in the path
of a portion of the outer end of the locking bar. When the locking bar, turning
with the cam sleeve, reaches the bevel or incline the bar will be pushed inward and
out of engagement with the notched collar, whereupon the cam sleeve will cease
to rotate and the motions of the line carriage the justifier, the distributor, the
primary depressor, the moveable aligning bar and the first line releasing devices
are suspended until the recasting rod is pushed rearward to move the lever arm 234
out of the path of the locking bar which enables the latter to spring outward and
snap into the notch in the rigid collar. The motion of the parts, suspended as
above mentioned will then continue at the proper time. During the time the
locking bar is disengaged from the rigid collar the operation of the casting ejecting
and trimming mechanisms continue the line of assembled matrices remains motion-
less in front of the mold, and any desired number of printing bars can be obtained
from this line of matrices as will be obvious.
THE POT CUT OFF AND LOOSE LINE SIGNAL.
The base plate 140 carrying the justifier shoe 139 is provided at its lower end
some distance below the shoe with an arm or dog 239 Figs. 27, 30, 55 and 51,
pivoted at one end and slotted at the other for the passage of a screw 240 for adjust-
ing the slotted end of the arm or dog vertically. The arm or dog is constructed
with a rounded upward projection 241 adapted to bear against the end of the long
arm 242 of a bell crank lever 243 secured at its angle to the outer end of a trans-
versely arranged rock shaft 244 journaled in and extending through the solid front
panel or plate 124 of the machine. The short arm 245 of the lever 243 normally
bears against the upper edge of a strip pawl 246 pivoted at one end as at 247 to
the lower end portion of the guide leg 141 which guides one edge of the base
plate to which the justifier shoe is attached. The trip pawl is cut away or recessed
in its upper side as at 248 and is connected with one end of a spring 249 having its
other end attached to a pin on the front panel or plate of the machine. A lever
arm 250 is secured to the inner end of the rock shaft 244 and lies along the inner
side of the front panel or plate 124. This lever is connected at its left 'hand
extremity by a link 251 with a swinging pot cut off plate 252 pivoted at one end
as at 253 to the mold carrying frame 160. The link 251 connects the cut off plate
at one side of the pivot of the latter and the cut off plate is composed of a compara-
tively thin plate of metal preferably brass of sufficient width to entirely close the
mouth of the casting pot when the cut off plate is shifted directly in front of said
mouth as indicated by full lines in Fig. 55. The cut off plate is designed to he
lowered into position to close the mouth of the casting pot, as will hereinafter
appear immediately before the pot reaches a position to lock up the mold and line
of composed matrices. The vibatory lever 250 is connected to one end of a
spring 254 which at its other end is attached to the rear of the front panel

page_text: or plate 124 the tendency of the spring being to raise the long arm of the lever and
thereby elevate the pot cut off plate to normal position as in dotted lines Fig. 55
where it does not prevent or obstruct the free How of metal from the pot mouth
into the mold.
The base plate 140 and the justifier shoe 139 can rise the usual distance to operate
the space-bars for expanding and justifying a correct line without operating
the bell crank lever 243 but if the line of assembled matrix and space-bars be loose
or of a length insufficient to be expanded by the space-bars the distance necessary
to make a tight line in the line carriage the base plate and the justifier shoe carried
thereby will unduly rise, because there is insufficient resistance to the upward
motion of the justifier shoe as is the case in a correct or tight line, such undue
upward motion of the base plate and justifier shoe being rendered possible by the
presence of the spring yielding link 145. When the base plate 140 unduly rises
the rounded extension of the arm or dog 239, strikes the long arm of the lever 243
and by raising the same forces the short arm 245 to the right until it passes off
the upper edge of the trip pawl to the cut away or recessed portion 248 whereupon
the pawl snaps or springs up from the position indicated by dotted lines in Fig. 55
to the position shown in full lines and the short arm of the lever bears against the
shoulder formed by the recess in the pawl. As the trip pawl springs a spring
pressed trip dog 255 pivotted to the pawl acts upon a tappet 256 provided at the
outer end of a rock shaft 257 to sound the audible signal as will hereinafter appear.
The upward motion of the long arm 242 in the hell crank lever 243 turns the
rock shaft 244 in the direction necessary to throw the lever 250 in a downward
direction thereby pulling the pot cut off plate down and placing it in position to
cut off or close the mouth of the casting pot when the pot is advanced and its
plunger is operated.
The metal therefore will now flow to the mold, which would be very objectionable
if a loose line of matrices or no line were presented to the casting mechanism.
The rock shaft 244 is journaled in and extends through the front panel or plate of
the machine and the inner end of the rock shaft is provided with a bell hammer 258
designed to sound a hell or gong 259 supported at the inner side of the said front
panel or plate. The rock shaft is provided with an arm or lug to which is attached
one end of a spring 260, in such manner that when the trip pawl 246 snaps or
springs upward and operates the tappet 256 the rock shaft is turned, the spring 260
is stretched and the hell hammer is moved away from the bell, but the instant the
trip pawl slips past the tappet the spring 260 turns the rock shaft back restores
the tappet to normal position indicated by full lines in Fig. 55, and causes the
hammer to sound the bell or gong, thus giving the signal to the operator which
indicates that a "loose line" is in the line carriage at the justifier whereupon the
operator can instantly stop the machine, or permit it to continue its motions as the
pot cut off lies in a position to close the pot mouth and prevent the passage of
metal to the mold. The trip pawl is provided on its outer side with a lateral
pin 261 adapted to be acted upon by a suitable dog 262, Figs. 23, 24 and 25
pirotted to the inner side of the line carriage in such manner that when the line
carriage subsequently moves from the casting point back to normal position the
pivotted dog is held against swinging and acts upon the pin 261 to force the trip
pawl 246 down to be engaged and held down by the short arm of the lever 245.
the spring dog 255 yielding to permit it to pass the tappet 256. The parts are thus
reset, as shown in full lines Fig. 55, for a subsequent operation if a loose line
should exist in the line carriage after the justifying shoe is operated.
The arm or dog 239, on the base plate of the justifier shoe, is adjustable, as
before set forth, to regulate its position relatively to the long arm of the bell
crank lever 243, to suit the conditions required.
The pot cut off mechanism can be used independently of the loose line signal
devices, that is to say, the latter can be omitted without affecting the operation
of the pot cut off mechanism. Further, the loose line signal devices can be operated
if the pot cut off plate is dispensed with. The invention therefore is not confined

page_text: to the employment of the signal devices in connection with the pot cut off mecha-
mism, nor to the employment of the pot cut off mechanism in connection with the
loose line signal devices, as either or both may be employed, but it is advisable to
employ both in substantially the manner described and shown as by this means
the usefulness of the machine is enlarged.
THE STARTING AND STOPPING MECHANISM.
As
The main or line shaft of the machine is placed under control of the operator by
devices some of which are similar to those employed in the former machine.
regards the automatic stopping of the main shaft at the end of each cycle of
motions, and the means for operating the roller which actuates the cam on the
oscillator, desirable and advantageous improvements have been made which
materially simplify the machine and contribute to making it certain effective and
reliable in operation.
The spindle 271, Figs. 1 and 4, which corresponds to the shaft on which the
pinion in the former specification is loosely mounted, instead of being geared
to the driving gear of the machine, as before, is provided with a loose pulley 272
driven by suitable power, as for instance by a belt connection with an overhead
driving shaft. The nave of the pulley is provided with notches as at 273, designed
to be engaged by projections, as at 274, on a handle knob 275 which rotates with
the spindle, but is movable along it, in such manner that when the knob handle 2
be pushed in to engage its projection with the nave of the loose pulley the latter
is caused to rotate with the knob handle and the spindle 271. The spindle carries
the serrated or toothed roller 36 which operates the serrated or toothed rotary
cam 20 as hereinbefore explained.
Thus the spindle carrying the roller which actuates the cam of the oscillator
is driven by driving mechanism entirely independent of and disconnected from the
driving gear or mechanism which transmits niotion to the main or line shaft. The
object of this, as herein before stated, is to simplify this part of the machine, to
render it certain and reliable in operation and to place the roller under control of
the operator, without any positive connection with the driving gear which operates 3
the main or line shaft.
The rotation of the main or line shaft is effected by a driven pulley 276.
Figs. 1 & 63, the shaft of which is provided with a pinion 277 gearing with a
wheel 278 attached to a tubular shaft 279, Fig. 62, supported in suitable bearings.
The tubular shaft also carries a loosely mounted pinion 280 geared to the toothed 3
driving wheel 290, on the line shaft 92, as in the former machine. The pinion 280
has a nave which enters the annular nave of the wheel 278 and is formed on its
inner end with teeth 281 constituting one member of a clutch. The other clutch
member is composed of a toothed collar 282 loosely mounted on the tubular shaft
and placed within the annular nave of the wheel 278.
4
The toothed collar 282 is secured to a clutch shaft 283 arranged within the
tubular shaft and pressed outward by a spring 284 acting against the inner end.
Instead of providing the projecting end of the clutch shaft with a grooved collar
to engage the bifurcated end of the clutch operating lever 285, as in the former
machine, the inner end of the clutch shaft 283 is provided with a rounded 4
extremity bearing directly against the front end of the clutch operating lever 285
which is pivotted at its rear end as at 287 and is provided at its left hand side
with a lateral abutment or stud 288 designed to co-operate with a stop dog or
pawl 289 pivotted to the toothed drive wheel 290 on the main shaft. The dog or
pawl is pivotted to the right hand face of the toothed drive wheel as at 291, as best 5
seen in Fig. 64 and at its outer end it is constructed with a segmental slot 292
through which a pin 293 passes into the toothed driving wheel. The pawl is
provided with a projecting finger 294 and is connected to one end of a spring 295
which at its other end is attached to the right hand face of the toothed driving
wheel. The action of the pawl will hereinafter appear.
5.
The clutch operating lever 285 may be pushed to the right to force the clutch

page_text: shaft 283 inward, by means of an incline 296 at the inner end of a slide bar 297
which by a rod 298, Fig. 27 is suitably connected with the lever 102 at the left
hand side of the keyboard to be conveniently reached by the operator. The hand
lever 299 is fixed to a rock shaft 309 extending under the keyboard to which shaft
the lever 102, which operates the radial lever 101, is attached. When the hand
lever 299 is swung rearward the slide bar 297 is moved rearward and its incline 296
forces the clutch operating lever 285 to the right, or inward, thereby disengaging
the clutch sections so that motion is not transmitted to the driving wheel 290 on
the main or line shaft and the latter instantly ceases to rotate.
When the hand lever 299 is swung outward the clutch operating lever 285 is
released and the spring 284 at the inner end of the clutch shaft 283 forces the
latter outward, or to the left, to engage the clutch sections, whereupon motion is
transmitted to the driving wheel on the main or line shaft.
The main or line shaft is automatically stopped after each cycle of motions of the
machine, that is to say, after the line carriage has been shifted from the com-
posing to the casting mechanism and has returned to the composing mechanism
by means of the dog or pawl 289 which has its finger 294 bevilled on its underside
to set against the abutment or stud 288 on the clutch operating lever 285 to force
the clutch shaft 283 inward and thus separate the clutch sections, whereby the
transmission of power to the main or line shaft shall cease and the latter instantly
stops. When this occurs the finger of the dog or pawl lies in engagement with
the abutment or stud 288 of the clutch operating lever and it is necessary to
remove the dog or pawl from such engagement before the clutch shaft 283 can
move outward to engage the clutch sections and transmit motion to the main or
line shaft. To accomplish this result, the operating hand lever 299 is pushed
rearward to force the clutch operating lever 285 to the right to such a distance
that the finger 294 of the dog or pawl can by the slotted construction of the dog,
and quick action of the spring 295, snap past the abutment or stud 288 and thus
offer no obstruction to the instant movement of the main shaft driving wheel 290.
The operating lever handle 299 must be moved forward to subsequently start the
machine.
