Improvements in and pertaining to Printing Telegraphs, Typewriters
and the like.
[A communication from abroad by CHARLES LUMAN BUCKINGHAM, of 195 Broad-
way, New York, State of New York, United States of America, Lawyer.]
I, WILLIAM LLOYD WISE of 46 Lincoln's Inn Fields, in the County of London,
Consulting Engineer and Chartered Patent Agent, 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 :
-
This invention relates to apparatus by which printing may be done at high
speed, in page form, by operating the apparatus, type by type. While the machine
is in some rospects adapted to the purpose of an ordinary typewriter, when used
with a suitable key-board, it is primarily designed for reproducing, in page form,
telegraph messages sent over a wire at a high rate of speed and by apparatus
operating automatically after the manner of a Wheatstone transmitter, or by other
telegraphic apparatus.
By means of this apparatus, messages are printed upon sheets of paper whose
edges are pasted or otherwise fastened together to form a tube which is thereafter
placed upon a stationary tube or support and given rotary and axial movements
for feeding the same from one letter or space position to the next and from line to
line throughout a message. The particular object of the invention is to effect such
rotary and axial feed of the paper tube positively; and to this end, an escapement
wheel is employed which is subject to a continuous propulsive action imparted by a
motor. The escapement wheel is provided with a number of teeth equal to the
number of characters in each line upon the page and is directly connected through
a train of spur wheels with the paper in such manner that from the beginning to
the end of the message the sheet shall be positively and mechanically geared with
such wheel. That is to say, the paper tube is fed circumferentially step-by-step
for each letter and axially from line to line under the direct action of the escape-
ment wheel through a train of gearing which directly connects the paper tube
with said escapement. And as a special means for enabling such gear connection,
there is provided in the lap or double thickness of the paper where the edges are
pasted together, a line of perforations into which the teeth of a small spur wheel,
positively joined with the escapement wheel, are made to mesh, and with which the
teeth of said spur wheel are in gear connection throughout the printing of n
message.
The invention further consists of other and more specific means of improvement
hereinafter set forth.
In the accompanying drawings, Figure 1 represents a side view of a printer of
that class in which messages are printed upon sheets of paper first made into tube
form.
Fig. 2 is a plan view showing a stationary support for the paper tube, the type-
wheel and dogging thimble, and a part of the gearing for rotating the blank or
Daner tube.

page_text: Fig. 3 shows circumferential and diagonal grooves surrounding the stationary
support, and a slot parallel with its axis within which the feed wheel may be freely
turned at its initial position.
Fig. 4 represents a small block within which the diagonal grooves are formed,
and which is thereafter inserted within the stationary support with the diagonal
grooves matching those surrounding the tube.
Fig. 5 shows a small feed wheel, the teeth of which mesh within the grooves
surrounding the stationary support and the holes of the paper tube, together with
a directing guide for circumferentially adjusting said wheel so that its teeth shall
pass within the circumferential grooves of the tubular support at the first feed of
the message blank, at the beginning of a line.
Fig. 6 is asectional view showing the stationary support the train of gear for
rotating the paper tube and mechanism for circumferentially adjusting the small
wheel so that its teeth, upon the first step of rotation, shall enter the circumferential
grooves of the tubular support.
Fig. 7 represents a sectional view through the fixed support for the paper tube,
the dogging apparatus for setting the type-wheel and a train of gearing by which
a feed action is communicated from the step-by-step escapement to the paper tube
or blank.
.
Fig. 8 shows the small spur wheel and its supporting bracket.
Fig. 9 represents the spur wheel meshing with the row of holes in the lap of the
paper tube and mounted upon a wheel of the train connecting with the step-by-step
escapement.
Fig. 10 represents a paper tube or blank showing a row of holes in the lap
formed by the double thickness of the paper where its edges are lapped and pasted
or otherwise fastened together.
Figs. 11, 12, 13 show a modification of the arrangement of Figs. 1 to 6, the
particular device here outlined having for its object the lifting of the teeth of
wheel from the grooves of the tube at an initial point, or when one paper tube
is to be removed upon the completion of a message, and a new one inserted.
Fig. 12 shows the circumferential and diagonal grooves of Fig. 3 with the slot u
omitted.
Fig. 13 represents a modification of apparatus shown in Fig. 6.
Referring to Fig. 1, a represents a metallic tube rigidly supported at its right
end upon a bracket, b, affixed to a base plate, c. Upon the metallic tube a is placed
a sheet of paper formed into a tube by pasting or otherwise fastening its edges
together; and upon this tube messages are printed line by line in page form. In
other patents describing this plan of printer are shown various forms of apparatus
for moving the paper tube, but in previous arrangements there exists the difficulty
that for each line the paper is liable to be fed too far or not far enough, thus
rendering the left margin of the printed page inexact or crooked, while in soMA
instances letters which should appear upon a
end of lines preceding. To avoid these difficulties, a train of gearing is employed
succeeding line aro printed at the
which joins the escapement or step-by-step wheel of the printer with the paper
tube in such manner as to positively convey to the latter the movements of the
wheel both for circumferential and axial feed.
In Fig. 10 is shown a sheet of paper formed into a tube, T, whose overlapping
edges when pasted together, are perforated with a line of holes, h, h, into which the
teeth of a small spur wheel f¹, shown in Figs. 5, 6, 7, 8, and 9, are made to mesh,
whereby the paper tube may be given a circumferential feed a step at a time for
each succeeding letter, and axially from line to line in forming the page. The
train of gearing for connecting the escapement wheel with the paper tube is
represented in Figs. 1 to 9. In this organization is a ratchet wheel upon whose
shaft is rigidly fixed a wheel which meshes with wheel upon whose shaft is
also placed a larger wheel ¹, gearing with a large ring wheel 7, which surrounds &
the tubular support a, and which is itself supported on friotion rollers m, m³, n, n'.
The ring wheel is of diameter considerably in excess of that of the supporting

page_text: tube a, and, its diameter is sufficiently greater to permit said spur wheel f' to be
mounted within the ring wheel in such relation that the teeth of f¹ may project
through the holes in the paper tube into circumferential or diagonal grooves
formed in the periphery of the tubular support. Thus as the escapement or
step-by-step wheel is permitted to rotate, its movements are imparted through
spur wheels i, k, 2, 7, to the small spur wheel, the teeth of which projecting
through the holes of the paper tube, carry the latter circumferentially from ono
letter position to the next around the stationary tubular support. This train of
gearing is subject to a continuous propulsive action from a motor, e, Fig. 1, gearing
with the shaft d, which in turn, by a beveled gear, f, g, imparts a winding tendency
to one end of a coiled spring, the other end being connected with the shaft upon
which the spur wheel is mounted and by this means, with each movement of
the escapement pallets, which control wheel j, the train of wheels connecting j with
the wheel is given a step of rotation. The teeth of wheel j, with the exception
of a blank portion, are equally spaced over its periphery and are of a number equal
to the characters to be printed in each line of the message, while that portion of
the periphery upon which no teeth appear is of sufficient length to permit an
abnormally long step of rotation a step usually made equal to six or seven of the
shorter steps; and it is by this means that the paper tube may at a single step of
the escapement be permitted to rotate a distance representing that between the
two margins of the printed page. The escapement here referred to is operated by
magnet and an armature R, which is pivoted upon a shaft R' upon which is
carried a suitable bracket and pawls 4 and 5, the pawl 5 being fixed or rigid with
reference to its supporting brackets, while 4 is movable around an axis, 6. By this
means, as armature It is attracted, pawl 5 is drawn into a space between adjoining
teeth of the ratchet wheel while pawl 4 is disengaged. This action, however,
permits the escapement wheel to move only a very small distance, while at the same
time, pawl is disconnected from the wheel, and by means of spring, 21, is
caused to move backwards in a direction opposite to the rotation of the escapement
wheel, and into such a position that upon the retraction of armature R it will drop
into the next notch just before pawl is disconnected. That is to say, just
before disengagement of pawl 5, pawl 4 will be thrown into that cavity of the
wheel next back of the one which pawl 5 had left, thus leaving the wheel, under
the action of the propelling motor, free to rotate an additional step.
Although the invention is not limited to any specific form of ring wheol 7, or
device for carrying wheel ' around the tubular support, a preferred construction
is shown in Figs. 1 to 9, in which is represented a ring having horizontally
projecting edges or flanges, s, and a surrounding series of spur teeth.
By this
means, wheel is easily mounted and retained in position to mesh with spur
wheel, since by such arrangement friction rollers or guides m, m, n, n¹, having
ceutral grooves, serve to support the wheel both circumferentially and axially.
The peripheries of these rollers serve as guides and supports for the flanges ss,
while their central grooves afford a passageway for the spur teeth of the wheel,
the sides of said grooves at the same time serving to hold the said wheel in an
accurate axial position. Upon the inner periphery of the wheel / is affixed a
bracket or shoc, particularly shown in Figs. 5, 6, 7, and 8, within which is pivoted
the small spur wheel f
As shown in Figs. 7, 8, and 9, a bracket piece, a¹, is joined to b¹ by means of a
yoke having arms 1 and 2, within which is pivoted a shaft gl carrying the spur
wheel f; and to secure the bracket to wheel 1, the arms a¹ b' are preferably
provided with screw holes d' by means of which its convex surface may
be tightly
bolted to the inner periphery of 7, as shown in Figs. 6, 7, 8, and 9. In forming
this bracket, however, the yoke piece c¹ of Figs. 8 and 9 may be omitted and
structure substituted like that shown in Figs. 5 and 6.
Preparatory to the printing of a message, spur wheel f' is brought into a pre-
determined position with reference to the tubular support, and while f' is in this
position the tubular blank is pushed along the stationary support until the first

page_text: holes in the lap of the tube are brought into mesh with its teeth. One means by
which this may be accomplished is shown in Figs. 3, 7 and 9, in which is employed
a small slot cut into the tube lengthwise slightly at one side of a central line.
If wheel f is brought into the plane of slot u, obviously it may be rotated and the
paper tube thrown forward since the teeth of f¹ will find a clearance in the slot,
and, at the same time, will mesh with the holes h of the tube T. To accomplish
the circumferential feed of the paper tube, wheel is swept circumferentially
around the tubular support a, its teeth at the time being stationary with reference
to its own axis, they being held within the circumferential grooves r, s, t, of tho
tubular support, as shown in Figs. 7 and 9. At the end of each line of the message,
however, the teeth of wheel f' are brought into the inclined grooves ', to', ., and
by this means said wheel is given a rotation equal to the angular space covered by
two of its teeth and a distance equal to that from one line to the next; and it is by
this means that the paper, while given a circumferential rotation representing the
distance between the two margins of the page, is also moved axially a sufficient
distance for a new line.
Thus it is seen that the spur wheel f¹ while bodily carried by the ring wheel 1,
has its teeth projecting through the holes in the paper tube T into the circum-
ferential grooves in the tubular support and that said wheel is held stationary
upon its own axis during the printing of a line, while thereafter it is rotated
sufficiently to move the paper for a new line as its teeth are moving through the
inclined grooves u, to, r¹. To the end, however, that the teeth of wheel may
move freely past the slot u, the inclined grooves, w¹, r', are terminated a short
distance at the right of the slot, whereby the teeth of the wheel after passing the
inclined grooves, must find their normal position within the planes of the circum-
ferential grooves before reaching the position of the slot. To further insure against
the catching of the teeth of wheel in passing slot u', the wheel may be provided
with a small check wheel having several concave or notched sides within which
the curved ends of a spring or dog p may press. By this means, the teeth of fl
can have only such a normal position as must insure their entrance within the
circumferential grooves after passing slot u'.
A check wheel and a spring p, or some substitute device is particularly
necessary in determining the position of the teeth of wheel f' when a blank for a
new message is to be inserted. Without some such arrangement, the teeth of the
wheel would be left in any angular position, so that upon the first operation of the
feeding device they would be liable to be caught upon the ends of the ridges
between the grooves of the tube.
A preferred form of apparatus for setting the teeth of wheel is shown in
Figs. 1, 2, 3, 4, 5 and 6, in which the operation is automatically performed by the
action of a manual device which is employed for engaging and disengaging the
pallets of the escapement. But in this case check wheel ql and spring p may be
and preferably are omitted. Another device adapted to the same purpose is shown
in Figs. 11, 12, and 13.
In carrying out the invention there is employed manual means for connecting
and disconnecting the escapement wheel from its pallet, whereby at the end of a
message, if only a part of a line has been printed, the escapement wheel and its
accompanying gear may immediately return to a zero position; and such manual
apparatus is further employed for connecting the feed train with a fly or retarding
apparatus, whereby, upon releasing the escapement wheel from its pallets the train
may run rapidly to a unison position, but without undue shock.
As shown in Figs. 1, 2 and 6, ml is a rod which, when pulled to the left, dis-
connects the escapement wheel from its pallets and joins with the feed train a
Hy, Connecting with this rod is an upright stud, 27, to which is attached a
cord, 28, passing under a grooved wheel, 29, upward over wheel 30, and thence to
a stud, 43, which is attached to a sliding har, 35, the latter being supported in its
various positions upon an arch bracket 31. The arched support 31 is provided with
oblong holes, 32, 33, 34, and within these openings pass bolts 36, 37, 38, which are

page_text: attached to bar 35. Also rigidly fixed upon bar 35, as shown in Figs. 2, 5 and 6,
is a downwardly projecting arm, 39, upon one end of which is formed a wedge-
shaped guide, the point of which may, when wheel is in its normal position, be
thrust between any pair of its teeth in such relation as to so move wheel f', that
its teeth must find the grooves r, s, t, after leaving slot ul.
To the right end of bar 35 (Fig. 6) is connected one end of a U-spring, 41, while
its other end is fixed upon the arched support 31. From this arrangement, it will
be seen that when rod m" is pushed in, cord 28 will be pulled downward, thereby
drawing the carrier 35 to the right, and with it the setting pin, 40, or into a
position to set the teeth of wheel into their proper position, both at the com-
mencement of a message and at all times in the printing of a message as the blank
is being rotated over its long step, and while wheel is passing the slot u. It
will also be seen that, at the same time, the escapenient wheel is thrown in gear
with its pallets, while the fly is disconnected from the driving train.
Upon
pulling rod ml to the left, however, the carrier 35 is thrown to the left by spring 41
and with it the point 40, thus carrying said point back out of the path of wheel /',
thereby leaving the latter free to rotate within the slot at the time of inserting a
paper tube for a new message. Thus it is seen that the pull rod, while connecting
and disconnecting the escapement wheel from its pallets, actuates a movable cam
or guide for setting the teeth of wheel f¹ into proper position, the wheel previously
having been left free to rotate within slot for the insertion of a message blank.
Manual apparatus for connecting and disconnecting the escapement, and means
for bringing the paper tube to a unison position at the end of a message are
particularly shown in Figs. 1, 2, 5, and 7. The rod m" carrying a hand-button at
one end, has an arm near the other which engages in a groove, 8, cut in the hub of
the support of escapement wheel j. Another part of the hub carrying the escape-
ment wheel is provided with a slot within which slides a pin, 10, the latter being
connected to the driving shaft, while upon an auxiliary disk fastened to the escape-
ment wheel is a tooth, 7, the end of which, in normal rotation, clears a fixed
stop, 22, but which, when rod m" is pulled to the left, is brought into the path of
said stop, whereby as the escapement wheel is disengaged from its pallets, stop 7 is
put into a unison position; that is to say, in such a position that wheel f' will at
the time be in the plane of slot u'.
The
Referring to Figs. 11, 12 and 13, there is affixed to the inner periphery of wheel 7,
a bracket or shoe, within which is pivoted the small spur wheel f. In Fig. 13 is
shown a bracket formed of legs, a', 'b', fastened upon or within the ring 1, between
which project the teeth of wheel f, while upon b', at 40, is pivoted a lever having
two arms, 38, 41, upon the latter of which is mounted wheel f'. Upon the free end
of arm 38 is a horizontally projecting pin, 39, which, during rotation of ring 7,
may come in contact with cam 36, formed at the free end of lever 31, the latter
being pivoted at 30. As the paper tube arrives at that point of its rotation where
the long step takes place, pin 38 may, when cam 365 is depressed, come in contact
therewith and thereby raise spur wheel fabove the paper tube, and sufliciently
far to remove its teeth from the holes in the lap of the tube and from the circum-
ferential and diagonal grooves formed around the stationary support.
special purpose of this arrangement is to enable paper tubes to be easily
removed from or placed upon the tubular support. In the normal operation of the
machine, cam 36 is in an upper position and as ring wheel makes one revolution
after another, pin 39 and cam 36 will not come in contact with each other.
the end of a message, however, when escapement wheel is disconnected from its
pallets, cam 36 is depressed into a lower position whereby, as the escapement wheel
rotates into a zero position, pin 39, is depressed near the latter part of the move-
ment, and while the teeth are passing through the diagonal slots e', ', r', they
are lifted therefrom and entirely away from the paper tube. As shown in
Figs. 11 and 13, m" is a horizontal rod which is pulled by the operator in bringing
wheel to the left away from the escapement pallets, 4, 5. This, as already
described, in connection with preceding drawings, is done by means of an arm 36
At

page_text: having a forked end surrounding the slotted portion, h, of the hub of said wheel.
Upon the pull rod is also a pin, 35, which engages with the slotted end of arm 34,
pivoted at 33, which, as rod m" is moved, draws rod 32 downward and with it
lever 31. Thus, as the escapement wheel is released and as unison pin 7 comes in
contact with stop 18, cam 36 being depressed, the teeth of wheel f¹ are lifted from
the grooves surrounding the stationary support of the paper tube. Upon thrusting
the pull rod m back to the right or into its normal position, cam 36 is raised above
the path of pin 39, whereupon wheel 39 is lowered and its teeth pressed into the
holes of the paper. As a means for positively depressing wheel fl a spring, 37,
shown in Fig. 13, is employed, the free end of which bears beneath arm 38. In
this arrangement the slot of Fig. 3, is no longer necessary from the fact that,
at the time of inserting a paper blank, wheel f¹ is lifted entirely above the paper
tube and away from the grooves of the stationary support.
B
An essential condition in operating the escapement is that its wheel shall not
rotate at the time of actuating the press mechanism, or when armature Ris
attracted by M¹. It should only rotate when armature R is moving into a back
position or after an impression has been made. A further condition is that, at
the end of a message, when it is desired to let the apparatus or train run to zero, the
oscapement wheel should be disconnected from the fixed pallet of the escapement
rather than from the movable pallet. If the wheel were disconnected, from the
morable pallet and not from the fixed one, re-engagement would be with the
movable pallet and thereby one false step of rotation would take place, causing
derangement of the lines of the printed message. To avoid this difficulty, the
escapement magnet, wheels and pallets have been arranged, as shown in
Figs. 6 and 7, in which, for unison disengagement, the escape wheel is moved to :
the left, assuming, at the same time, the armature R to be attracted so that
stationary pawl 5 shall normally be in a position to arrest the teeth of the wheel.
Upon disengagement, the wheel is pulled along its axis to the left of 5, leaving it
free to rotate, and by this means it is apparent that when rod ml is thrust to the
right the teeth of the wheel must be pushed back over the rigid tooth of the escape-
ment, thus, at the beginning of a new line, leaving the escapement wheel in the
axact position it would have occupied if disengagement had not taken place.
If a message were completed after having printed only a few characters upon a
line and the escapement wheel were disengaged from its pallets, the feeding train
would move to unison position with great rapidity. To avoid injuring the 3
apparatus by unnecessary blows, a train of gearing carrying a fly or fan, as already
described, has been provided, as shown in Figs. 1 and 7, which is connected to the
shaft of the escapement wheel at the time the latter is disconnected from its
pallets. This organization has been specifically described and claimed in the
specification of preceding English patent No. 15215 of 1895, and it therefore 4
constitutes no part of the present invention, except as it is a part of the combination
of the new positive feed arrangement. As here shown, a clutch 11 and 12 is
normally disengaged, the free portion thereof being connected to fan 13; but upon
pulling rod m to the left to disengage the escapement, parts 11 and 12 engage
with each other, thus joining the fly with the escapement train.
4
As shown in the specification of said former patent No. 15215 of 1895, a rubber
band is carried within the tubular support between the type-wheel and the press
hammer. In such instances, however, this band is rotated by the action of a
wheel within the tubular support, and is driven by a friction feeding device acting
from without the tube; but as the friction device is now omitted, it is necessary 5
to employ other means for actuating such band. As shown in Figs. 6 and 7, 19 is
the rubber band, which is carried around two upper rollers, 20, and a single lower
roller, 18, placed upon a shaft, 17, the latter being provided with a ratchet
wheel, 16, with whose teeth an arm, 15, attached to the press lever, engages. By
this means, with each movement of the arm p, the band 19 is given a slight 5
movement, and during continued operation its entire length is repeatedly brought
opposite the small aperture 21, through which the platen acts upon the type.

page_text: Said band 19, however, need not be automatically moved. It is found sufficient
in practice to manually move it a short distance from time to time.
The tubular support a is made in three sections, to, r, y, which are separated by
joints, a, as shown in Figs. 3 and 7. Sections w, and y, are preferably of brass
tubing of a circumference slightly less than the width of the paper sheets, of which
the message tubes are formed, while the middle section, a, is of iron whose shell is
thicker than that of to and y, and particularly that part within which the circum-
ferential and inclined grooves for controlling the position of the teeth of spur
whee! fare cut. A further detail of this construction is shown in Fig. 4, which
consists of a small block of metal having a cylindrical and convex surface within
which the diagonal grooves,,, are cut. Corresponding with such block,
the tube section, r, is provided with an aperture and within this aperture is
closely fitted the block, thus forming an arrangement of the circumferential and
inclined slots, as shown in Fig. 3.
The circular and diagonal grooves, however, may be cut upon an integral
tubular surface thereby avoiding the imperfect joints that are liable to result from
the use of a block placed within an aperture as shown in Fig. 4.
