Improvements in Type-setting Machines.
We, THE DOW COMPOSING MACHINE COMPANY, a corporation organized under
the laws of the State of West Virginia. U.S.A., and carrying on business at
Park Row Building, New York, U.S.A., and ALEXANDER Dow, of 25, Pine Street,
New York, U.S.A., Engineer, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
Our invention relates to an improvement in that class of machines known
as type assembling devices or type setting machines; that is to say, that class
of apparatus whereby printers' type are automatically taken from reservoirs or
cases containing the same, by the operation of the mechanism of the machine
as controlled from a key board, and are set, in the form of words and sentences,
with appropriate spacing between them.
Broadly speaking, our invention relates generally to a novel machine for com-
posing printers' type into words and lines mechanically. This operation is
performed by the uniting of co-operative mechanism into an organized apparatus,
whereby from a key board, an initial movement is given to the apparatus, which
movement is completed by the operative mechanism of the machine, automati-
cally acting to set the type. This organized machine embraces several subor
dinate combinations which co-operate to make up the assembled machine, and
yet which in themselves are complete operative mechanisms, which in their
relation to the assembled device may be termed the subordinate combination of
elements, and the subordinate combinations of elements may be regarded either
in association with the assembled machine, or individually, as separate apparatus
working together as a complete invention, which combinations may in them-
selves be used in connection with other appropriate devices which they may
co-operate. These subordinate combinations may be classified as follows:
First, type reservoirs or cases in combination with an assembling table, so
arranged as to feed the type to the assembling table, as the same are required
in the operation of the machine; second, devices for ejecting the type from
the reservoirs or cases and delivering the same upon the assembling table;
third, a type driving apparatus-that is to say, devices operating to collect the
type, as the same are delivered on the assembling table, and to deliver the same
at a slot or type channel; fourth, devices, for subjecting the type to a uniform
restraint during the period of their movement on the assembling table under
the operation of the assembling mechanism; fifth, devices for positively forcing
or expelling the type from the assembling table into the slot or type channel.
Our machine may be specifically classified as one wherein individual types
are selected, and delivered on an assembling table, and thence driven to a type
channel or slot, located approximately in the center of said assembling table,
and forced into said channel. to the end, that the type are assembled immediately
in front of the operator of the machine and may be reviewed by him as they are
assembled by the machine; and are delivered to the slot or channel in the center

page_text: of the assembling table from each side alternately, to the end, that the assembling
mechanism has a minimum travel and is capable of very rapid movement. It
is also a machine operating positively; that is to say, by positive mechanical
movements, as distinguished from natural forces such as the forces of gravity or
electro magnetism, the operation of the device being dependent upon the force
of gravity alone in the matter of the feed of the type in the channels of the
reservoir and here equivalent mechanical forces may be employed. Further-
more my apparatus causes the type to be delivered on the assembling table,
lying upon their sides, thus presenting to the operating mechanism bodies con-
stantly varying in thickness, to which condition the said mechanism auto-
matically adjusts itself.
We have illustrated our invention in the accompanying drawings and desig-
nated the parts by letters, referring to like parts by like letters.

We will now describe the several parts of our apparatus dividing the same as
best we may into groups, in order that the same may be more clearly under-
stood. In the first place we will describe the frame of the machine with its
operative connections and the assembling table which becomes part of the frame,
when considered in relation therewith.
FRAME OF THE MACHINE AND ASSEMBLING TABLE WITH OPERATIVE CONNECTIONS.
is the table which forms a base plate for the operative mechanism of the
device. a, a, etc., are bolts intended to hold said table a¹ to suitable supports,
such as a³, a³, etc., which are intended to rest upon the ground. A and A. are the
two uprights of the machine, which are suitably braced together, preferably by
the stays and ², which are suitably secured to said frame by the nuisa
and is what we term an assembling table, for the reason that the type
are ejected from the type reservoirs upon said table, and are forced across the
face of said table, to a slot in the center of said table, where they are assembled
or brought together. This table as is secured between the uprights A and A,
and becomes a brace between said parts of the frame. is a slot or aperture
in the table 8, running parallel with the length thereof, and intended to be
of a size to receive the type cases or frames of the type reservoirs which will
hereafter be more fully described. a", a¹, etc., are blocks of metal milled out

page_text: to form ways for the ejector bars hereafter to be described. These milled
blocks are shown in Figure 37, and are intended to rest in the apertures a
which are provided for the same in the table as a is an apron, preferably
made as part of the table a8. a¹³ is a brace secured between the two uprights
of the frame A and A, and operates also as a hanger, to which are secured metal
blocks and a, etc., similar to those described under the title "; that is to
say, milled to operate as guides for the ejector bars hereafter to be described.
als is a brace suitably secured between uprights A and A, intended to operate as
a support for certain hangers and other devices, which in like manner operating
as a support for, and co-operating with, the ejector bars. is the base of what
I term a hanger for the jector bars; it is provided with the brackets a, a,
between which is supported the bar is a cushion bar suitably supported
by the helical springs and 2, at either end thereof, and by said springs
secured to a cross bar as. One of these cushion bars a is appropriately sup-
ported beneath each group of ejector bars. It will be seen in Figure 7 that
there are four groups of these ejector bars, and we therefore provide four of these
cushion bars and appropriate supporting frames for each one of these groups.
to
is a journal bearing within the upright of the frame A, Figure 36; this
journal bearing is duplicated in the opposite frame of the machine corresponding
to the one shown in Figure 36; but it is deemed unnecessary to illustrate the
same. 20 is a socket to receive a spindle to carry the operative crank lever, of
the assembling mechanism, hereafter to be described. 21 and 2 are brackets
upon which the table 8 is mounted, and to which said table is secured by the
bolts and a shown in Figure 37, is an aperture in the table
receive the elastic type channel, which is shown in detail in Figures 29, 30
and 31, and which will be hereafter more fully described. 2, etc., are apertures
in the apron a, by which the cushion bar, hereafter to be described, is secured.
The flexible slot within the table 8 and aperture is described as follows:
We provide two walls and for said slot, which slot is designated as a³.
These are pivoted together at , and are adapted to fit into said aperture a³,
the knife spring as being interposed between one wall of the aperture 23 and
the back of the wall 27 to cause the wall 27 to move in the direction of the
wall. The wall is fixed within the aperture 2 by the bolts, and the
wall a moves upon the pivot, and under the action of the spring 28. We
provide also the bolt, which is secured within the aperture, and adapted
to move within the elliptical slot, whereby the movement of the wall 27 is
limited. and a are spaces provided in the top of the walls and as, to
receive the heads of the dogs 25 and 25, hereafter to be referred to; these spaces
are of sufficient size to permit the movement of said dogs within said spaces for
purposes hereafter to be described. The slot between the walls and 27 and
within the table as is designated as a This slot is intended to receive the
type, and during the passage of the type through the same a certain friction
is brought to bear upon the same by the action of the spring as, and when said
type, by means hereafter to be referred to, is forced through said slot or
channel a, it passes through an appropriate type channel or race way to a point
of delivery. We have indicated this race way as a, and the same is shown in
detail in Figure 13.
We will now describe what we term the type reservoir or type cases in their
detail of construction.
TYPE RESERVOIR OR TYPE CASES.
We purpose in the construction of this type reservoir, is to provide columns
of type, supported in cases; said type lying side by side, each case containing
type representing a single letter, standing at a slight inclination as shown in
Figures 1 and 2; the lower surface of the bottom type in each case being in
the plane of the surface of the assembling table. To this end we construct a
frame and provide the same with a handle B, etc. In the operation of my

page_text: a
machine we employ four of these frames as indicated in Figure 1. This frame
is constructed with two side bars, and b, and a top bar, 62, with a base bar, 3,
forming the base of the frame."
is a post secured within the table as and
preferably within the aperture a, and b is a socket in said base to fit over
said post 6 The construction of the base 3 is of particular interest and will
now be described. The walls and 66 are preferably made as part of the base b³,
and the spaces are milled out of said base to leave said walls 66 and 6, and
each of said walls is provided with the shoulders and . This detail is shown
in Figures 38 and 41. The milled space 68 is of a width to receive the type in its
uniform width and form a permanent type channel in which the column of type
rests. We also provide a rear support for the type channels which forms also
a back for the base of the frame. We have designated this rear support or cross
bar as . It is secured to the base bar of the frame by the screws 10 and 10.
We provide this bar with the milled channels 11, etc. These channels are
arranged in line with the milled spaces 68, and are of an elevation corresponding
with the width of the type, which are fed to the channel opposite which they
are located. 12, etc., are type channels preferably made of thin metal to carry
a column of type lying side by side, and we prefer to make the base of said type
channels 62, with a bell flange such as 3 and 63 adapted in their construction
to rest on the shoulders 67 and, which thus form a support for the type channels.
It will be understood that these type channels are readily removable from their
position, as indicated in Figure 38 and elsewhere. We have indicated
column of type within one of these channels as . It will be noted that the
lowest type in, said channel which we have indicated in Figure 40 as 16 is on
a level or in the plane of the surface of the table 8, as indicated at 1 and ¿¹.
In the operation of this reservoir or type case, the frames having handles B, B,
B, B, are each provided with preferably twenty-four type channels such as 12.
Each of these type channels are loaded with types, as indicated at 6, and con-
taining characters of a similar kind: that is to say, all of the types bearing
characters representing the letter A will be in one channel, and that of B, in
another and so on. In some instances, which will be hereafter described, we
load two or three channels, as the case may be, with similar types, where the
types are of that kind which is more frequently used than others in the opera-
tion of type setting. I may load these type channels by hand, or through the
operation of a machine, known in the art as a type distributing machine. When
the channels are appropriately loaded I place the frame within the machine so
that the base of the frame & rests within the slot or aperture of the table 8,
and is supported by the cross bars and a³. The correct position of the reser-
voir within the slot is determined by the post and socket ; that is to say,
the socket must be over the post, before the frame can find its seat within the
aperture 4. When in position, as last described, it may be again noted that
the type stand in column, one upon the other, the lower part of the column rest-
ing on the base of the channel 68, and rising through said channel into the remov-
able channels 61, forming the column of types 65. When the type frame is
placed in position within the table as heretofore described, the lowest type
in each column is maintained by the base of the channel 68, on a level with or
in the plane of the surface of the table 8, as indicated in Figure 40, which figure,
it will be noted, is a section of Figure 38 on the line 40. We will presently
describe how the lowest type in each column may be ejected from the reservoir
upon the table; but it may be as well to note here that the types rest one upon
the other, forming a column and that they descend to the surface of the table
by gravity as the lowest type of cach column is ejected.
We will now describe the operation of what we term my selector and ejector
apparatus that is to say, a selector device operating from a keyboard to perform
an initial movement, to select the particular type, that we desire to be ejected,
and then the ejector device, by which the type is actually ejected upon the
assembling table.

page_text: THE TYPE SELECTOR AND EJECTOR APPARATUS.
The movements employed in this device are, an initial movement, controlled
manually by the hand of the operator, according to the arrangement of a key
board, and a mechanical movement, operated in conjunction with the moving
parts of the machine to eject the type, this movement is uniform and automatic.
The several parts of this apparatus may be described as follows:
C is a key board constructed according to any of the well known forms or
arrangements of such key boards best known in the art of typewriting machines.
The selection of the type emanates from this key board, under the hand of the
operator. We have illustrated the operation of this selector and ejector appara-
tus as in vertical section in Figure 3, where it is shown in association with the
other devices with which it co-operates, and we have illustrated it as taken,
apart, by itself, in association only with the devices with which it directly co-
operates, in Figures 17, 18, 19, 20 and 21, and we have limited my illustration
to the operation of one key for the reason that all the keys operate in a similar
manner and the illustration of one is sufficient to illustrate all. then may
represent the entire. key board as well as a single key. This key forms one
arin of a forked crank lever, which is suitably mounted and pivoted at c¹, and
provided with the arms 2, 3 and 4. is a rod suitably hinged to the end of arm,
and carrying the tongue . is a guide to receive the rod secured to the
hanger a is a binding post suitably mounted and is a helical spring inter-
posed between the binding post 8 and the arm with its tension directed to nor-
mally maintain the key C in position to be operated upon. is a cushion plate
suitably secured to the apron a12 by the bolt c¹ and provided on. its under side
with elastic material c¹ to receive the shock of the key lever c, as the same is
retracted by the tension of the spring c. 3 is also a cushion below said arm
to receive the shock from the hand of the operator. is one of the ejector
bars and c is an ejector. 16 is a square lug, being part of the ejector bar c¹³,
and is a recess in the ejector c. This detail is shown in Figure 6, when the
square lug c is seated within the recess c, the ejector c¹ becomes part of the
ejector bar and moves therewith. The ejector bar e is provided with certain
shoulders, against which the operative parts hereafter to be described operate,
to move said ejector bar backwards and forwards. We have designated the
shoulders as follows: e18 is a shoulder which is engaged by the end of the arm c²
to perform what we call the initial movement. is a shoulder which is engaged
by a revolving blade operating automatically to drive the ejector bar forward
to the full limit of its throw, and 20 is a shoulder engaged by a spring trigger
to retract the ejector bar to its normal position. is a beveled shoulder to
engage certain contact points, which are part of a device employed by us to
exercise upon the type a certain resistance during their movement on the assem-
bling table. This beveled shoulder will be more fully referred to hereafter.
The ejector bar is also provided with a recess for the tongue. 23 is a crank
lever suitably pivoted and provided at one end with a head or knob c and con-
necting at the other end, with a helical spring 2, secured to a binding post 26.
28 is a cushion bar suitably mounted on a bracket 29 on which is also mounted
said trigger 3, the said bracket being secured to the table or brace a. 30 is
an inclined plane secured to the table a, and 31 is a cushion bar preferably hav-
ing a metal core with an elastic covering, adapted to rest between the abutting
end of the ejector bars, and the inclined plane.
Referring to Figure S, 11 and 12, we will now describe in detail the apparatus
which has for its purpose the shifting of one of the levers above described,
so as to bring the same into engagement, with either one of three of the ejector
bars. The purpose of this device is to provide means by which, by the operation
of one key of the key board, the lever connected therewith, may be brought
to operate upon one of three of the ejector bars controlling the type in as many
type channels; that is to say, where three type channels being side by side are
loaded with type representing the same letter, as, for instance the letter A, and

page_text: in the course of the operation of the machine it is found that one column of
said type is exhausted, the operator by the use of this shifting device which
we am now about to describe, may cause the lever to shift, so as to engage
the ejector bar on either side of its normal position, and thus cause said ejector
bar to operate upon one of the other of said columns of type, thus giving to
the machine a capacity of three columns of type for each key, if such an
arrangement should be desirable. The construction of this detail is as follows:
is a sleeve suitably secured within an aperture of the apron a12. This
sleeve is provided with notches and substantially as indicated in Figure 12.
33 is a rock shaft journalled within said sleeve and is knob carried by
said rock shaft 33" is a crank arm secured to the end of said rock shaft
and and are guide pins secured to said rock shaft. These pins are indi-
cated in Figure 11 where it will be noted that the arm 2 is held between said
guide and and when the crank arm is rocked by the rock shaft in one
direction, the arm is brought against the guide, and in line to operate
another ejector bar. is a helical spring secured at one end to the rock
shaft and having its bearing against one end of the sleeve 2. 46 is a cross
pin, carried by the shaft 3.
co is a guard bar suitably secured to the table by the guide screws 42,
these guide screws carry helical springs bearing upon said bar to main-
tain the same normally in contact with the surface of the table a8. The bar 40
is suitably milled or cut with channels of a depth to receive the type as
the same are rejected from the type reservoir and of sufficient size to permit
said type to pass through said channels. The spring is interposed to permit
the bar to rise should a type of abnormal thickness be forced out of the
reservoir under abnormal conditions, which will be hereafter specified. e is
a main shaft of the apparatus hereafter described upon which is mounted the
blade secured to said shaft by the screws With the revolution of said
shaft said blade & engages the shoulders to force the ejector bar forward
to the limit of its movements for the purposes which will be hereafter described.
It may be here noted that the cushion bar is provided to permit a yielding
of the ejector bar as the same is engaged by the blade should there be any
abnormal resistance to the operation of said ejector bar.
We will now describe the operation of what we call the ejector and ejector
mechanism in connection with the cases or reservoirs of type heretofore des-
cribed. In addition to the description which is heretofore given of the appara-
tus, it must be understood that the shaft e, shown in section Figures 17, 18
and 19, is a main shaft, journalled within the frame of the machine, carrying
the beveled blade e, and that this shaft is kept in constant rotation during
the operation of the machine. These features will be more fully described
hereafter, but for the present purpose the foregoing is deemed to be sufficient
reference thereto. To a complete understanding of the operation of the mecha-
nism, it must also be made clear that each one of the keys of the key board is
intended to control directly, one ejector bar carrying one ejector, and that
each ejector is intended to operate upon the lowest type in one column of
type contained in one of the type channels, such as 612. It will, therefore, he
understood that Figures 17 to 21 represent the complete operation of the
selector and ejector mechanism, and it will be also understood that all of the
ejector mechanism by which the type are selected and ejected from each of the
type channels are duplicates of the one shown in said drawings and heretofore
described. It will, therefore, be clear that a description of the operation of
one of these selector and ejector mechanisms will be sufficient as a description
of the whole.
Referring to Figure 17, we have shown the apparatus in its normal position of
rest, wherein one of the keys of the key lever C is elevated in a position to be
depressed by the hand of the operator. We have also shown the table 8, with
one of the type channels or reservoirs 12 and a column of type 41 within the

page_text: same, resting at the base of the channel 8 within the base of the frame b³ and
flush with the surface of the table as in the line 14, 14. We have also shown
all of the selector and ejector mechanism, the operation of which in conjunction
with said type channel we will now proceed to describe. It will be understood
that the key illustrated in Figure 17 is the one corresponding to the type in
the type channel shown. This being the case when the operator desires to set
a certain type represented by said key, as for instance the letter "A," he will
depress the key C, until the type bar crests on the cushion c¹³. This operation
will perform what I term the initial or selecting movement, which consists in
first, the elevation of the lug out of the recess, thus releasing the ejector
bar from its locked position. This unlocking movement is performed in the
partial movement of the key C and in the completed movement of said key the
arm is brought into engagement with the shoulder 18 of the ejector bar c¹4
and said ejector bar is moved forward, that is to say towards the type, a dis-
tance indicated in Figure 18; that is, sufficient distance to bring the shoulder c¹
into the operative field of the beveled blade in the course of its revolution,
said revolution being indicated in dotted lines. The effect of this contact between
the shoulders and the beveled blade 44 is illustrated in Figures 19 and 20,
where it will be seen that the ejector bar is driven forward with the revolution
of said beveled blade 44 to its full throw, that is to say, until in the revolution
of said beveled blade e, the edge of said blade leaves the shoulder, as
shown in dotted lines Figure 19, and the complete throw is shown in Figure 20.
where it will be noted that the ejector 15 has engaged the lowest type 16, of
the column of type and has ejected the same from the channel 12 upon the
surface of the table a8. It may be noted here that the ejectors which are
secured to the several ejector bars c¹ are regulated in thickness according to the
thickness of the type upon which they are intended to operate. I have now
described the operation whereby the type are selected by the initial movement
of one of the keys of the key board and how they are ejected upon the table by
the operation of the revolving beveled blade c. We will now describe how the
ejector har 4 is retracted to its normal position, cushioned and locked. As the
ejector bar is moved forward by the beveled blade 44, the shoulder 20 is brought
in engagement with the head 24 of the trigger and said trigger is drawn
back to the position shown in dotted lines in Figure 19, against the tension of
the spring. When therefore the beveled blade e in its revolution leaves the
shoulder, the ejector bar c¹ is left under the operation of said trigger
and spring and is thereby retracted. The trigger, is, however, arrested
in its movement by the cushion bar 28 as shown in Figure 17; but the abutting
end of the ejector bar 14 is driven against the cushion bar which I have
heretofore described as made with a loaded core, and a cushioned covering.
The operation is therefore to drive said cushion bar to a limited degree up the
inclined plane 30 upon which it rests, and thus to cushion the retraction of the
ejector bar. The ejector bar rebounds from this cushion, and lug c falls into
recess, thus locking the ejector bar in position for a further operation of the
device.
It may also be noted in this connection that the ejector c¹³ first passes through
the milled slots 6 etc. In the cross bar shown in a rear view in Figure 41.
It then operates upon the type to eject the same, as shown in Figure 19, and
the type 61, Figure 19, passes beneath the bar of said figure: that is to
say, through one of the milled slots of said bar as " of Figure 9 and Figure 10.
This bar is interposed as a guide for the type in their passage to the table.
As the ejector is retracted and withdrawn from beneath the column of type 65,
it falls under the action of gravity or under the pressure of an appropriate
mechanical device, should such be deemed expedient, and rests on the base of
the channel 8 and on a level with the surface of the table 8 and in position
for the next operation of the ejecting mechanism. From the foregoing it will
be noted that the operator, by manipulating the keys of the key board, brings

page_text: the apparatus into the operative position, that is to say, performs what we call
the selecting of the type and by the automatic operation of the devices hereto-
fore described, the type is ejected. This we call the ejector apparatus.
We may also note that we interpose beneath the ejector bars c¹, and cushion
bar a, this cushion is provided for the purpose of counteracting a condition
which might occur, that is to say, an engagement between the edge of the
shoulder c, and the edge of the blade c, in which case the cushion a would
yield under such pressure.
TYPE DRIVING MECHANISM.
We will now describe what we call the type driving mechanism; that is to
say, the mechanism by which we assemble or collect together the type as they
are ejected upon the assembling table, and bring them to the central channel a
We have heretofore described this assembling table, with its central slot or type
channel, and we have specified the mechanism by which we select and deliver
the type from the type reservoir upon the assembling table.
The present
description assumes that one type is ejected upon the assembling table 8, as
in Figure 25, and it is the purpose of the devices which are about to be described
to deliver said type at the slot a. The construction of these devices may be
described as follows:-E is à bar suitably secured between the braces A and A,
preferably by screws, as c¹, or otherwise. This bar E serves the purpose of a
side bar, and is T-shaped in form, as indicated in vertical section in Figure 14
and 24. Upon this T-shaped guide bar are mounted the slide bearings (28
and, secured together by the plate 30 and e³ are adjustment screws to
take upon any wear of the bearings. e5 is a stud secured to the plate e, by
which the bearings 28 and 29 are secured. Upon this stud 5 is mounted the
connecting rod 6, which is suitably secured at e to the driving lever 8, the
same being pivoted at e upon the stud 20. el is a connecting rod, connecting
the other arm of the driving leveres to a stud on the side of the wheel e. The
disk 2 is mounted on one end of a shaft e¹, which is suitably sustained in the
journal bearings el3 and el, which are supported by a suitable bracket connected
with the frame A, and at the other end of the said shaft e" is suitably mounted
a beveled gear e¹. The shaft e¹6 and e¹ is suitably journalled in the bearings es
and e, in the walls of the frame A and A, and said shaft is provided at one
end with a pulley e17, by which power is conveyed to the machine, and at the
other end with a beveled gear e, adapted to engage with the beveled gear e¹5.
It will be readily understood that the power thus conveyed through this train
or gears and shafting is the power which operates the mechanical movement of
the machine. Upon the shaft e¹s and e¹ are mounted the beveled blades and
the cam wheel h7, hereafter to be described. Through the operation of the crank
arms connected with the stud e, a reciprocating movement is given to the carrier
formed of the face plate e and the bearings 28 and 28.
We will now describe the type drivers, which are supported by being secured
to the bearing 29. These type drivers are intended to drive the type from the
position at which it is delivered on the assembling table to the central slot, or
type channel. The construction of these drivers is shown in elevation and also
partly in section in Figure 13 and in vertical section along the lines 14-14
of Figure 14 and in vertical section along the lines 15-15 in Figure 15. The
description of the parts is as follows: el is a bracket secured to the under side
of the bearing 29. The wall of said bracket which is at right angles to the
under side of the bar is provided with the guides 20 and 20 shown in Figure 14,
and with the screw-threaded hole 21 and are parallel walls provided
with the ways 23 and 23 to receive the guides 20 and 20. These plates and e23
are secured together by the driving plate 2, which is shown in Figure 26. This
plate is made of a thickness less than the thickness of the thinnest type which
may be delivered upon the assembling table, and as heretofore stated, it is secured
between the said walls and at the base thereof and is intended to engage

The operation of this assembling device is shown in Figures 22 to 26 In
Figure 23, it will be noted that the parts supporting the type-drivers are given
a reciprocating movement and it is intended that this movement shall be of
great rapidity, it being necessary to the successful working of the machine that
each of the type-drivers should make one complete movement more rapidly than
the operator can select a type by the key board. It will be evident, therefore,
that this being the case, it would be impossible 'or impracticable, for the machine
to deliver more than one type upon one side of 'the assembling table during the
interval of the reciprocating movement of the type-drivers. When a type is
delivered on the assembling table, as designated in Figure.25 by 616, the driving
plate which is carried by the walls and they in turn by the reciprocating
carrier, engages the said type and forces. "the same into a position

over the slot. Should any obstruction arise in
of the
type, we provide the cushion spring to relieve the shock that may
be incident to driving the type against such obstruction. It will be readily
understood that the plates 23 and 2 will slide on the guides 20 and 20 and the
spring will yield to such pressure. This cushioning spring is necessary in
the event of two type of the same thickness being delivered upon the assembling
table at the same time, in which event the spring will compensate for the
presence of the extra type at the point of delivery.
AMENDMENTS.
It will be noted that the screw e screws into the bracket e and it will be
readily understood that this screw will control the relative throw of the type
drivers in their relation to the central channel e, that is to say, with the
movement of these screws the drivers and may be adjusted nicely, so
that in their reciprocal movement, they will deliver the type exactly over the
type channel a
It may be well to note here also that when I assemble the type driving
apparatus and the type restraining device, in the organized machine, the
walls and sustaining the type driver, span the friction bars g¹3 which
moves vertically between them.
We will now describe the operation of a mechanism by which we subject the
type during their movement by the assembling device upon the assembling table
to a certain friction which operates as a restraining force to maintain the type
under the action of the driving mechanism of the assembling device. We call this
THE TYPE RESTRAINING AND CONTROLLING MECHANISM.
"
"
We have heretofore stated that when the type are delivered upon the assembling
table they rest upon one side, and as the side-wise dimensions of the bodies
of the several letters of a font are seldom the same ranging from the lower
case "i" and "t" which are the thinnest to the upper case 15 which is the
thickest, it is necessary that a friction bar which may be used to exercise a slight
pressure on the upper surface of said type for the purposes heretofore explained
of controlling their movement, should automatically adjust itself to admit be-
neath whatever type is presented and rest lightly thereon. For this reason we
have advised the apparatus which we are about to describe.
G is a bracket suitably mounted on the table 8 and provided with journal
bearings; g is a journal bearing in the frame A. 92 is a rock shaft suitably
journalled in the bearing g¹ and the bracket G. is a crank arm suitably

and adapted to receive the vertical bar 99, with a helical spring interposed in
said sleeve, with its bearing upon the upper end of the rod 9º. g3 is a friction

and 18 is a connecting rod connecting the spindles g15 and 928 919 and 19 are
crank arms, carrying between their ends the cross bar g20, and the cross bar 20
is arranged to carry the contact points 9 etc. A section showing these contact
points is illustrated in Figure 34, in which it will be seen that contact points
are formed of screw threaded points passing through said bar 20 and provided
with nut locks 922. In Figure 32 it will be noted that the connecting rod gl
is provided at one end with an aperture 923 to permit the free movement of said
connecting rod in one direction in relation to the spindle g¹.
.
In the operation of the friction bar ga upon the type, we find it is necessary
to interpose at the end of the friction bar some means to arrest the movement
of the type upon the assembling table 8, when said type under the action of
the type-driver reaches the central slot. We therefore provide two dogs, one
at each end of each friction bar with abutting heads. In Figure 15 at gl we have
shown a vertical section of one of these sliding dogs, which we have also desig-
nated in Figure 16 as g; it will be noted in Figure 15, 5, that the dogs are
beveled in form, and adapted to slide in beveled ways, one in each friction
bar g3; each of these friction dogs is provided with the heads 26 and 2; and
arranged to abut one against the other, and to move uniformly, backward and
forward, yet the arrangement permits each of them to be in a different plane, for
the reason that their abutting cheeks engage each other without preventing a
vertical movement.
We will now explain the operation of the type restraining device which we
have just described in detail. As heretofore stated, the purpose of this device
is to exercise upon the type during their movement upon the assembling table,
a certain friction, which it is desirable should be the same upon each type, what-
ever its thickness. This friction is brought to bear on the type during their
movement on the table, to give to such movement a precision and certainty for
the purpose of restraining such movement, against the pressure of the type-
drivers, so that the type may be always held in control whilst being acted on
by the type-drivers.
As we have heretofore explained, the type are delivered upon the assembling
table, lying upon one of their sides, thus presenting to be acted upon by the
friction bar bodies constantly differing in their thickness. It is necessary there-
fore to provide means by which said bar 13 will be elevated above the plane
of the assembling table, just enough to permit the type which is to be ejected
upon said table, to pass under said friction bar g³, and yet said bar g¹³ must
have a certain friction bearing upon said type in order to obtain the result
which we accomplish by this mechanism. We therefore, regulate the device so
that the elevation of said pressure bar g¹³ may be varied as each type is ejected
upon the table. We do this in the following manner: we provide the contact
points shown in section in Figure 34, and we screw these contact points into
the cross-bar 20, to form contact points on the under side of said bar of different
lengths. I have heretofore described how these contact points engaged the
bevel shoulders of the ejector bar c¹, in the operation of forcing said ejector

page_text: "
bar to its complete throw, as heretofore described. It will therefore be under-
stood that as any one of the ejector bars is moved forward in the performance
of its complete movement, the contact point which is arranged to engage the
cam-shoulder 21, of the particular ejector bar which is operated, will cause the
crank arm g¹ to be lifted, as the contact point engages said beveled shoulder and
with it will be moved the crank arm g, connecting rod 918 crank arm g, crank
arms and g and hence the friction bar g¹³ will be lifted, according to the
degree of depression or elevation which is given to the contact point g¹ in
question.
The apparatus which we have just described may be termed a rocking frame,
by which the friction bar is lifted with the movement of any one of the ejector
bars. It is our purpose, in the operation of our device, to deliver not more
than one type on each side of the slot of the assembling table with each com-
pleted movement of the type-drivers. Hence it follows that the friction bar gla
may be maintained at any predetermined degree of elevation or at any pre-
determined distance from the surface of the assembling table during the passage
of each type. For this reason, we have provided two rocking frames, each carry-
ing. one friction bar, adapted to exercise a certain friction upon the type during
its movement beneath said bars, and, as it is intended that only one type shall
be presented beneath each of said bars during the said operation it is only
necessary that said bar should be maintained at one elevation or distance from
the surface of the assembling table during the movement of said individual type
upon said table. For the purpose of lightening the operation of the organized
apparatus, and reducing the friction upon the contact points 921, and ejector bars,
we have divided each of these rocking frames so that only part of. the working
apparatus of the frame is moved with each engagement of the contact point effect-
ing the same. We accomplish this result by the slot g2 in the connecting
rod 18. It will be understood, from an inspection of Figure 35 in connection
with Figures 32 and 33, that when one of the contact points engages the beveled
shoulder of one of the ejector bars, one of the spindles gl5 will slide within the
space 923, while the other spindle will be engaged by the hooked end of the con-
necting rod 18 and drawn backward in the operation of the rocking frame.
We will now describe the means by which we force. each type, as it is brought
over the type channel in the assembling table, into said channel ³, and thence
into the race way a³7.
THE TYPE FORCER DEVICE.
His a bracket suitably secured to the brace 13 h² is a shaft carried by said
bracket, and h¹ is a rock lever suitably mounted upon said shaft 2. is an
idle contact roller adapted to engage the cam h². h is a metal plate secured to
the other end of the rock lever . This plate is provided with an aperture h
leaving two forcer blades 6 and . h is a double cam wheel mounted on the
shaft and 48 are two eccentric elevations forming the double cam h.
h is a binding post. h is a hole in the rock shaft h¹, the helical spring 10
being interposed between said binding post and said rock shaft with its tension
directed to maintain the roller 3 in contact with the cam.
The operation of this forcer is as follows: With the revolution of the cam
the shaft his rocked and it is retracted by the spring . By this operation
the forcer blades h and 6 are moved from their position shown in Figure 27:
that is to say, slightly above the level of the table a8, to their position shown
in Figure 28; that is to say, slightly below the surface of the table 8.
In the arrangement of the organized machine, we so adjust the relative opera-
tion of the type assembling mechanism, and the forcer device, as to cause the
type-drivers e, in their movement operating from both. sides of the central slot,
to deliver the type to the slot at the same moment or immediately before the
operation of rocking the lever h¹, by which the type forcer h6 is caused to move
from the position shown in Figure 27 to that shown in Figure 28. Hence it

page_text: will be understood that the type are driven to said type channel from both
sides of the assembling table, traversed by the reciprocating type-drivers, and
at the same instance that each type is brought over said type channel 4, the
forcer mechanism acts upon the same to force the type into said channel.
We have heretofore described the construction of our machine in detail and
the operation of each one of the subordinate combinations which go to make
up the organized machine. We will now describe the operation of my organized
machine; that is to say, the operation of the assembled combination in co-
operation.
We have devised and heretofore patented a machine for distributing type
after the same have been assembled, said patent being numbered 26,636 of 1896.
By the operation of this device, or others that may accomplish the same result,
the type are distributed and delivered into the channels which we have hereto-
fore described, such as 612. These channels are placed, preferably to the number
of twenty-four, in each of the frames to which the handles B are attached. We
place these frames, preferably four in number, in the machinė, substantially as
shown in Figure 1. The column of type in .each channel immediately descends
to the base of the slot 68, and is therefore, on a level with the surface of the
assembling table, and as the lowest type in each channel is ejected from said
channel upon said table, the other type in the channel fall, under the action of
gravity, or any suitable mechanical device, to take its place in position to be
ejected.
We have found, in the operation of assembling or setting type, that there are
certain type which are more frequently employed than others. These are usually
found to be a, e, h, n, 0. We therefore find that it is desirable to load the
channels or type reservoirs with more of one type than another; that is to say,
we will provide two channels of a's, three of e's, two of h's, and so on, as I
find the necessities of the case may require.
We have heretofore described the manner in which I cause certain of the
arms c, of the key lever, to be so shifted, as to engage one of two, or one of
three, ejector hars, as may be necessary. It will be understood that there is one
ejector bar and one ejector for each type channel; hence where we desire to
employ three channels of 'a's, we place said channels together in one frame in
position to be operated upon by three ejector bars, which are under the control
of a single key as 2, and said key is operated by one rocking shaft as 3, and
one knob as 4. In Figure. 1, we have shown five of these knobs c, with the
letters indicated thereon. As the type are placed in the channels of the reser-
voir 6, the operator may read their characters as he is seated before the machine.
He can, therefore, observe how the type in each channel are being consumed
in the operation of the machine. If he perceives that one column, as of a's, is
being exhausted, he moves that one of the knobs, controlling the "a" lever c².
so as to bring it into position to act on the ejector bar controlling the next
column of type; and thus the operator, by the movement of the knobs 4,
controls three columns of type in the channels 6¹³.
It will therefore be manifest that the operator, may, by this device, draw from
three columns of type by one key without removing the type channels or frame:
when the whole or part of the type in the channels carried by one frame are
exhausted, it is. removed and replaced by another filled with loaded cases, or
reservoirs.
The machine is set in motion by the movement of the pulley wheel e". Thus
the power is conveyed along the shaft et, the shaft c1, crank levers and con-
necting rods, communicating with the stud, which is secured to the face
plate e, of the type driver carrier. With the revolution of said pulley e¹7.
the type-drivers 25 are caused to reciprocate over the face of the table a³, each
of said drivers 25 sweeping the table from the extreme throw of the crank
arm in one direction, to the edge of the slot in the other. Thus, whatever
type may be delivered upon the surface of the table 8, and beneath the friction

page_text: bar 13, it will be driven, or swept, by said drivers, between said friction bar
and the surface of the table, to the said slot, or type channel.
The shaft is provided with two beveled blades c, set in position shown in
Figure 3. As heretofore stated, these beveled blades are adapted to engage each
shoulder c¹ of each ejector bar c4, when said shoulder is brought into the field
of said blade. In Figure 7, it will be noted that one of these blades is adapted
to affect that group of ejector bars, that deliver type to one side of the assembling
table, and that the other is adapted to engage that group of ejector bars which
are arranged to deliver type to the other side of said table, and that these blades
are set on opposite sides of the shaft el, as shown in Figure 3, one being shown
in solid lines and the other in dotted lines. It will be understood that these
blades, only operate upon the ejector bars when the shoulder 19 is brought
into the field of their operation. The normal movement of said blades is one of
constant rotation and out of contact with the ejector bars c¹, a semi-circular
shaped space being, formed in said bars to admit the rotation of said blades with-
out engagement therewith.
The machine is thus set in motion, and we prefer that its operation shall be suffi-
cently rapid to reciprocate the type-drivers to deliver type to the type channel a³,
as fast as the operator moving the key board, can operate the same to deliver
one type at a time upon the assembling table; that is to say, one type upon
either side of the central channel of the assemgling table. In other words, it is
our purpose in the normal operation of my machine, to eject but one type upon
either side of the type channel, during the period occupied by one complete
movement of the type drivers.
The machine being thus in rapid motion, the operator may proceed to select
the type that he desires to be assembled, by operating the appropriate keys of
the key board C; that is to say, suppose, as a letter to be selected, the operator
chooses the letter "a"; to select the type corresponding with said letter, he will
depress the appropriate key operating upon the ejector bar, which in its turn
operates upon the column of type in the reservoir which contains the "a" type.
This operation has already been described: but it may be well to review the
same briefly, in order that all of the movements may be understood, in connec-
tion with the other parts of the apparatus. The depression of the "a". key,.
heretofore referred to, will first operate to unlock the ejector bar c¹, and to
move the said ejector bar forward a short distance, as indicated in Figure 18;
that is to say, sufficient to bring the shoulder c¹ into the field of one of the
beveled. blades 44. It being understood that these are revolving with great
rapidity, it will necessarily follow that as the edge of said blade makes.contact
with the shoulder c, the ejector bar e thus operated upon, will be driven
forward with considerable velocity, moving in the ways. 10 and a and the
ejector will be driven against the lowest type in the column of type contained
in the channel 613, and said type will be ejected from said reservoir or channel 613,
passing through the aperture provided to receive. the same in the guard bar-co
and thence it will be delivered upon the surface of the table. This move-
ment of the ejector bar c¹ also performs the other function of lifting the friction
bar 3 to an appropriate elevation above. the surface of the table as, to receive
the type delivered upon the table as last stated. This operation is performed by
the contact point engaging the beveled shoulder 2 of the ejector bar c As
the same is operated by this contact, the rocking frame by which the friction
bar g3 is controlled is rocked with a sufficient movement to elevate said friction
bar g3 above the table, against the pressure of the spring gl, a distance sufficient
to permit the type ejected from the channel 92, as heretofore recited, to. pass
under the said friction.bar g with a slight pressure; that is to say, the friction
bar is so adjusted as to bear upon the type under the action of the spring 12
and hold the same between its under surface and the upper surface of the table,
with a friction sufficient to operate as a restraining resistance to the movement
of the said type whilst being operated on by the type-driver The ejector is

page_text: then retracted under the action of the trigger and is cushioned against the
cushion bar 31, and falls into its normal position, and is finally locked by the
lug e falling into the recess and the friction bar g¹³ rests on the type depressed
by the spring 918.

"
It will be observed that the operation thus described contemplates several
movements: First, the operator depresses a key of the key board, representing
the letter which he selects; this I term the manual selection of the type as
distinguished from the mechanical operation by which the type are ejected, by
this operation the shoulder c9 is brought into the field of the revolving blade c
Second, the ejector bar is moved forward by said blade, and the type is delivered
upon the table, and by this same movement of the ejector bar the rocking frame
causes the friction bar g3 to be lifted to receive the. type, and restrain the move-
ment thereof upon the table; and third, the ejector bar is retracted.
and falls into its normal position and, as it is detracted, the column
of type descends so as to bring the lowest type into the position of that one. which
has just been ejected, and in position itself to be operated upon by the ejector c¹³.
It being understood therefore, that one type is ejected from the reservoir,
and delivered upon one side of the assembling tables, and is lying under the
uniform pressure of the bar g, the next movement is that of forcing the type
by the operation of the driver over the face of the table and delivering the
same over the type channel a. This movement is accomplished with great
rapidity and the type are driven or swept by said driver e25 toward the channel a34,
and at the same time, held by the friction bar between the under surface of
said bar, and the surface of the table. It will be understood that, by the
operation of the keys of the key board, the type are delivered upon one side or
the other of the type channel in the assembling table, and that the two type
forcers are constantly operating to force the type towards the said type channel,
and the two friction bars g¹³ are constantly exercising a restraining force upon
said type in their movement upon the table. But it will be readily understood
that the resistance exercised by the friction bar upon the type, might not be
sufficient to arrest the movement of the type directly in front of the type
channel For this reason, we have provided the friction dogs g and g with
the heads and. When the type is driven over the table beneath the
restraining resistance of the friction bar g13 and it comes to the end of the
stroke of the type-driver and in contact with the head g of the dog g³, the
dog is moved in its beveled ways to the extent of its movements, carrying with
it the opposing dog, and it will be noted that the limit of its movement will
positively arrest the movement of the type immediately above the type channel a¸
The next movement is, therefore, that of forcing the type from the position last
described into the type channel. This is accomplished as follows:-
We have heretofore described the operation of the type forcer; but it may
be well to note again how the same operates in conjunction with the operative
parts of the machine as assembled. The normal position of the forcer blades h
and is that shown in Figure 27 and it will there be seen that these forcer
blades span the friction bar g and stand immediately above the type just as
it is delivered, restrained by the friction dogs g, as heretofore described. At this
moment, one of the eccentric faces of the cam operates to rock the shaft h¹
and by this operation the forcer blades are brought in contact with the type,
delivered above the type channel, and the said type is forced into said channel g³
driving ahead of it whatever type may be already in the channel, and thus the
type are continually. forced into the channel and through the race-way a
It is the purpose of our apparatus to deliver the type upon the assembling
table, when the type-drivers are at the furthest limit of their movement away
from the central channel. We accomplish this result by so adjusting the relative
position of the forcer blade with reference to the type-drivers, as to bring the
said forcer blades into position to make contact with the shoulder c¹ of the

page_text: ejector bar, when the said type-drivers are at the limit of their movement. This
operation may be described in detail as follows:
The rotation of the disk e imparts to the type-drivers, a rapid reciprocating
movement, causing said forcers alternately to approach to and withdraw from
the centrally located slot in the assembling table, as has been described. The
only office of the type-drivers being to assemble the type as selected by the operator
and delivered on the table, into a composed line in the central channel.
Should the ejector deliver a type upon the assembling table in front of either of
said drivers as they move from the central located channel aforesaid, where it
is intended said type shall be assembled, the effect would be to force any type
so delivered, from the said slot instead of towards it. It is essential then to
the successful working of my machine, that the contact of the blade ct with
the shoulder c on the ejector bars, by which a type is delivered on the assembling
table should be impossible, whilst the type drivers e, are moving from the slot a³ to
the limit of their outward movement. We find it necessary therefore to so
adjust the time of contact on the blade c, with the shoulder c¹ of the ejector
bar, that the said contact can occur only whilst the type-drivers are changing
the direction of their movement on the assembling table from an outward direc-
tion to one towards the center of the assembling table. The adjustment by
which this is effected is made in the following manner: the main driving shaft e¹,
carries at one extremity the beveled gear wheel e, which is intended to engage
with the similar beveled gear es, carried by the short shaft e; it is necessary
that these two beveled gears should be of the same diameter, in order that the
two shafts aforesaid, shall rotate in equal times. Now it will be seen that
said shafts referred to, one carrying the beveled plates that actuate the ejector
mechanism, and the other actuating the assembling type-drivers e, may be so
set with respect to each other, that the blades c, for instance, can only engage
the shoulder c, of the selected ejector bar, whilst the type-driver, operating on
the same side of the machine, is changing from a movement outward to one
towards the centrally located slot in the assembling table, when these relative
positions of the blade and the type forcer have been made, as described, the two
beveled gears a³ and e15, (the machine being at rest), are made to engage, and
are then secured to their respective shafts in the usual way.
It is obvious from the foregoing description, that the two blades c++, are set
with respect to each other, at an angle of 160 degrees, so that they act alternately
first on the ejector bars of one side, and then upon those of the other. The relation
between the blade c** on one side, and the type-driver on the same side being,
that the blade e is adapted to engage the shoulder e, at the same time that
the type-driver on the same side of the machine is reversing its movement, and
starting towards the type channel a³. It will be obvious that the same adjust-
ment is employed on the opposite side of the machine, as regards the relative
position. Now when motion is imparted to the machine, it will be found im-
possible to deliver a type upon the assembling table, whilst either of the type-
drivers is moving from the central slot, and consequently, every type delivered
upon said table is forced to said centrally located slot, as described, and into
the assembled line.
There is one feature of the operation of our machine to which we desire to
call attention, as it may not be at first apparent from the foregoing description,
which is to the effect that under certain conditions, in the operation of the machine
there may be found one type on the assembling table beneath the friction bar
on one side of the central channel, and at the same time, a type on the other side
of the central channel and beneath the friction bar. The possibility of this
condition existing will make apparent the necessity of the employment of
two friction bars, one on either side of the central channel, for the reason that
if the type beneath the friction bar on one side of a greater thickness than the
type beneath the friction bar on the other side, and these two friction bars were
united together as one bar, then the operation of the friction bar would be such

page_text: that only the thickest type would be affected by the operation thereof; hence we
have employed two friction bars, one controlling the operation of the type on
one side of the central channel, and the other controlling the operation of the
type on the other side of the central channel.
The condition under which this operation may be seen, is as follows: Suppose
we depress two keys, one to effect the ejection of the type on one side of the
central channel and one to effect the ejection of the type on the other side of the
central channel, the machine is then set in motion, the type first ejected will
in the course of the operation of the drivers be swept toward the central channel,
and, the adjustment of the machine is such, that just before the arrival of said
type at the central channel, the ejector mechanism operating on the other side.
of the central channel will operate to eject the type selected as aforesaid; hence,
the condition will be manifest, that is to say, there will be two type on the two
sides of the assembling table at the same time; one of these type may be of one
thickness and one of another, and hence it is necessary in order that the friction
bars may be effectively operative upon the type, no matter what their relative
thickness may be, the friction bars must operate independently of each other. It
is evident, therefore, that when the machine is in continuous and regular opera-
tion, the question as to whether or not two type are in reality upon the table
at the same time, depends entirely upon the time interval between the depression
of two keys by the operator and when manipulated at nearly its full capacity, i.e.,
when a letter is set at each half revolution of the driving mechanism (when they
so happen to occur in words) it is apparent that two letters are present on opposite
sides of the assembling table very frequently, and hence, entirely independent
friction bars and their controlling mechanisms must be provided on each side
of the central channel, otherwise letters of variable width could not be con-
trolled.
The machine is so adjusted that the type are ejected upon the table, when the
type-driver, operating on that side of the central channel on which the type is
ejected, is at the extremity of its movement away from the central channel. In
my claims hereinafter, we have referred to the ejector mechanism as taking place
when the type-drivers are at the extremity of their movement. We do not intend,
by this language, to confine ourselves absolutely to the remote point of the
extremity of their movement away from the central channel; we simply intend
to convey that the ejector mechanism is operated at a time when the drivers are
withdrawn from the path of the type, as the same are or may be ejected in order
that there may be no collision between the type, as the same are ejected, and
the drivers, and in order that the type may be ejected before, and not behind,
the drivers that is to say, between the drivers and the central channel.
Having now particularly described and ascertained the nature of our said
