"IMPROVEMENTS IN PRINTING PRESSES, CHIEFLY APPLICABLE TO FOOT POWER."
[A communication from abroad by the Gilman Vortical Press Company, of Boston,
Massachusetts, United States of America.]
This Invention relates to self inking printing presses adapted to be operated by a
foot treadle, and the objects thereof are to provide improved devices for guiding
and turning the platen in its upward and downward movements; for operating the
ink roller frame carrier and ink table; for governing the movements of the tympan
fingers; for carrying the platen against the type bed with greatly increased power,
and for adjusting the face of the platen and of the type bed to perfectly parallel
planes.
I attain the above named objects by the mechanism illustrated in the accom-
panying Drawings, in which Figure 1 is a front elevation of the printing press

Figure 8 is a transverse section of one of the hollow posts a, a', and of the platen
shaft box, and the treadle connecting rod together with the end of the platen shaft
and a portion of the platen.
Like letters and numerals refer to like parts in the different Figures.
The bed B with its hollow posts a, a', table D, and stands c constitute the frame
of the machine. The bed B is provided with a suitable wide channel between the
posts a, a, for the reception of the usual printer's chase in which the type form is
locked, and said chase is secured in place under the platen by screws c through the
ends of the bed.
The platen A is provided with a shaft e whose ends project beyond the ends
thereof, and through boxes c¹ fitted to slide in the vertical slots formed in the walls
of the hollow posts a, a', adjoining the ends of the platen, and the flange on said
boxes is adapted to fill the space between the said posts and the ends of the platen,
and prevent end wise motion of the latter.
Two vertical rods d, d, whose ends are perforated transversely are hung one on
each end of the platen shaft e-within-the-hollow posts a, a,-as seen in Figures 1,4,
and 8, and extend therefrom down through the table D.
Said rods_d_are_made_in_two parts, which are united by means of a split right
and left screw coupling b, each provided with flanges and a thumb screw through
them, as shown by means of which said-coupling-can-be-securely-fastened-in-any-
desired position on said rods; and by turning said coupling thereon, the rods can
be nicely adjusted to such a length as the proper action of the platen moving
devices may demand.
A shaft is hung in proper bearings in the stands c parallel with the base of the
bed B, and is adapted to have a reciprocating rotary motion.
Said shaft is provided with two arms d¹ and d², and is bent for a short distance
between each of said arms and the ends of it into a double crank form, as seen in
Figures 1, 3, and 4, and centrally between its ends is fixed a segment of a circle f
adapted to carry on its periphery a wire rope or chain g, which is secured to one
end thereof, as shown.
The other or lower end of said chain or rope g is secured to a foot treadle E,
whose rear end is pivoted to a rod F secured transversely between the rear lower
ends of stands c; the lower ends of the aforesaid vertical rods d, d, are pivotally
'connected to the sides of the arms d³, a², at their ends by bolts passing through
them, as seen in Figure 1.
Two retracting springs H, H, are secured adjustably by chains, as shown, to
collars i, i, on said rod F, and their upper ends are secured (likewise by chains)
around shaft H at the base of arms d', d³, as seen in Figures 1 and 3.
A rod F is fixed between the lower front ends of stands c opposite rod F in the
rear.
On one side of the segment F near to shaft h is pivoted a pawl rod j, its end
next to said shaft bent in the form shown, and its opposite end is properly formed
to engage with the ratchet wheel K.
A spiral spring t is attached to the under side of the table D and to said pawl
rod, as shown.
A circular ink table M is attached to the upper end of a vertical shaft N, to the
lower end of which is attached the aforesaid ratchet wheel K, and shaft N is fitted
to revolve in a proper vertical bearing set in table D.
A frictional spring o is attached to the table and bears slightly against the under
side of the ink table M.
Attached pivotally to the bolt which passes through the arm d³ on shaft hand

page_text: the lower end of one of the rods d is a connecting rod o² made of the form shown
in Figure 3, and running up through the table by the end of the bed B is pivotally
connected to one arm of a bell crank lover o³ which is pivotted to an arm o
projecting from the hollow post a¹, as shown in Figures 2 and 3.
An arm of corresponding to said arm o* projects from hollow post a, and attached
pivotally thereto by a bolt q, Figure 5, is a swinging arm r.
A post projects from the upper side of the platen, as seen in Figure 1, and to
said post and to the side of the aforesaid arm o³ on posts a is pivotally attached a
connecting rod v, bolt 9 passing through its end at arm o³.
Said bolt has that portion of it which passes through said rod v turned
eccentric to its axis, as seen in Figuro 5. A set screw, as shown, is placed in the
end of arm o³, and adapted to be screwed against bolt a to prevent it from turning.
Connecting rod v is provided with clamp pivot holes, as shown, so that there
may be no lost motion in this connection.
One arm of the bell crank lever o³ is perforated transversely to receive the end of
a shaft 8 and the other end of said shaft passes in like manner through aforesaid
swinging arm r.
is an ink roller frame carrier consisting of the semi tubular longitudinal part 2,
and the parts 3, 4, of like tubular form, at right angles to the former, and having
an arm 5 projecting from said part 3, as shown.
The shaft & passes through the tubular portion 2 of the frame carriers, and the
latter has an oscillatory motion thereon.
The tubular parts 3 and 4 of said carrier are set a little to one side of the axis
of shaft 8, as shown, and are adapted to receive two posts 6 and 7 of the ink roller
frame won the upper ends of which are nuts 8, as shown.
Spiral springs 9 are placed on posts 6 and 7 between the carrier
frame w.
and the
A bent connecting rod 10 is pivotally attached to the side of the post a' next to
the platen and to the end of arm 5 on frame 3.
The ink rollers 11 are adapted to turn on shafts which are fitted to proper twin
boxes attached to the frame w, as shown, and are provided with collars near their
ends which roll on tracks 12 running transversely across bed B when the ink
rollers run off from the type form.
On the opposite side of the platen near its rear edge are provided two short
posts 13 which are perforated transversely for the reception of the tympan finger
shaft 14 which is splined longitudinally, as shown, and has a crank 15 formed on
one end thereof, and to the end of said crank is rigidly fixed a bent lever 16, as
shown in Figures 6 and 7.
Pivotally attached to the side of crank 15, as shown in Figure 6, is a rod 17
provided with adjusting nuts, as shown, and its upper end enters a hole forined
through a projection 18 on the back of the platen. A spring 19 is interposed
between said projection 18 and said nuts on rod 17.
The tympan fingers 20, of which there are two, having collars 21 formed on their
lower ends to fit on shaft 14 and bent in the form shown are secured on said shaft
by set screws whose points enter said spline in said shaft, and said fingers reach
from the shaft under the bottom edge and up in front of the platen, as seen in
Figures 3 and 7.
Fixed to the outer sides of the posts a, a, are two vertical rods 22 adapted to
support two brackets 23, each of which is adapted to support a paper table 24
pivotally hung on said brackets to one side of their centres.
The operation of the press is as follows, it being understood that the usual
provision of type form and ink has been made :-
The position of the operating parts of the press when the platen is up, presenting
its underside or face conveniently for placing the paper to be printed upon it, . is
that shown in Figure 3.
Upon pressing upon the foot treadle E, shaft h is caused to turn by the action

page_text: of the rope or chain g attached to the periphery of the segment f. As said shaft
turns, arms d', d², are caused to swing downward, drawing rods d connected to the
ends of the platen shaft e and the platen in the same direction.
Immediately that said downward movement begius, the platen commences to
turn on its shaft in boxes e¹ so actuated by the connection of the post x on the
back of the platen with the fixed arm o³ on post a of the frame through the
connecting rod v, and while moving down turns so as to bring its face squarely
against the type thereunder, or to the position shown in Figures 1, 2, and 4.
To enable the operator to so adjust the plane of the face of the platen that it
shall perfectly agree with the plane of the type face, means for slightly swinging
the platen on its shaft while nearly against the type are provided in the bolt q
connecting one end of the rod v with arm o³ By turning this bolt slightly its
eccentric portion causes rod v to move longitudinally in the direction required to
adjust the platen to the necessary plane, and when so adjusted the bolt may be
secured against turning by the set screw shown on one side of arm o³.
When shaft h is turned far enough over to bring the ends of arms d³, d³, down to
the position relative to the axis of said shaft, which the double crank shape of it
permits, before rods d can strike it, a very great pressure of the platten upon the
bed is produced as said arms and rods approach a corresponding line, and a powerful
printing impression is tho result.
While shaft h is revolved, as above stated, springs Hare elongated, and upon
lifting the foot from the trendle, their retracting power turns said shaft in the
opposite direction and lifts the platen back to its upward position.
Said springs, as heretofore set forth, are connected to collars i on-rod-F,-and-by-
turning and setting said collars-suitably-thereon-;-the tension-of-said springs.may_be_
increased or diminished as may be desired.
When shaft is revolved to bring the platen down, as above described, the pawl
body j is drawn towards the front of the machine, and when said shaft turns back
the end of said rod engages with the ratchet wheel K, and so turns the ink
table M partly around, spring t serving to hold the end of the rod against the
wheel.
It will be seen that the ink rollers in Figure 1 are shown in front of the
post a, a', having been brought into that position and across the type form from
the ink table as the platen moved up. Figures 1 and 2 show the position of the
said rollers and their actuating parts when the platen is down.
Simultaneously with the downward movement of the platen just described occurs
the backward movement of the ink rollers on to the ink table actuated by the
swinging of the bell crank lever o³ caused by the downward movement of rod o²
connecting it with arms d on shaft h.
The connection of the upper end of the ink roller frame carrier z with post a¹ by
the connecting rod 10 allows said frame to swing freely below said rod. Frame
obeys the oscillating motions of shaft 8, the latter being actuated by the movement
of the bell crank lever.
Thus cach time that the platen goes up the ink rollers are carried from the ink
table across the types between posts a, a', and when it descends they return to
said table and the springs 9 tend to force the rollers against the type bed sufficiently
to cause the form to be properly inked.
It will be observed that the tympan fingers, when the platen is up, spring away
from the face of the platen, as shown in Figures 3 and 7, and they are caused to
move to this position by the striking of lever 16 (Figure 7) against shaft s
when the platen swings to this position, but as soon as the platen has turned
slightly on its axis said lever is moved away from said shaft and springs 19
operating to drive rod 17 downward shaft 14 is revolved causing the fingers 20 to
quickly spring against the face of the platen and hold the paper placed thereon to
be printed.
The paper tables 24, supported on brackets 23 at the ends of the bed, are

page_text: provided with pivots placed on their under sides; one side of their centres and
said brackets may be swung backwards and the tables 24 be swung over the ink
table in such a way that they offer no obstruction to placing a box cover over the
whole upper part of the machine.
This press may be easily converted into a power press by any suitable attachment,
whereby shaft h is caused to have a reciprocating rotary motion, such as is given to
it by the treadle and its shaft connections and by springs H, in which case those
parts may be dispensed with.
By the construction herein described and shown a self inking foot power press is
provided, which is simple in construction, one in which an unusually large typo
form can be practically printed from, owing to the great power which operates to
force the platen down, and. in which the self inking devices are simple and
effectivo.

platen-shaft box and the treadle connecting rod, together with the end of the platen
shaft and a portion of the platen.
Like letters and numerals refer to like parts in the different Figures.
The bed B with its hollow posts a, a, table D, and stands c constitute the frame
of the machine. The bed B is provided with a suitable side channel between the
posts a, a, for the reception of the usual printer's chase in which the type form is
locked, and said chase is secured in place under the platen by screws c³ through the
ends of the bed.
The platen A is provided with a shaft e whose ends project beyond the ends
thereof, and through boxes e fitted to slide in the vertical slots formed in the
walls of the hollow posts a, a¹, adjoining the ends of the platen, and the flange on
said boxes is adapted to fill the space between the said posts and the ends of tho
platen and prevent end wise motion of the latter.
Two vertical rods d, d, whose ends are perforated transversely are hung one on
each end of the platen shaft e within the hollow posts a, a, as seen in Figures 1, 4,
and 8, and extend there from down through the table 1).
Said rods d are made in two parts, which are united by means of a split right
and left screw-coupling b, each provided with flanges and a thumb-screw through
them, as shown, by means of which said coupling can be securely fastened in any
desired position on said rods, and by turning said coupling thereou the rods can

page_text: be nicely adjusted to such a length as the proper action of the platen-moving devices
may demand.
A shaft is hung in proper bearings in the stands e parallel with the base of
the bed B, and is adapted to have a reciprocating rotary motion.
Said shaft is provided with two arms d' and d², and is bent for a short distance
between each of said arms and the ends of it into a double crank form, as seen in
Figures 1, 3, and 4, and centrally between its ends is fixed a segment of a circle f
adapted to carry on its periphery a wire rope or chain g which is secured to one
end thereof, as shown.
The other or lower end of said chain or rope g is screwed to a foot treadle E
whoso rear end is pivotted to a rod F secured transversely between the rear lower
ends of stands c. The lower ends of the aforesaid vertical rods d, d, are pivotally
connected to the sides of the arms d¹, d, at their ends by bolts passing through
them, as seen in Figure 1.
Two retracting springs H, H, are secured adjustably by chains, as shown, to
collars i, i, on said rod F, and their upper ends are secured (likewise by chains)

An arın o corresponding to said arm o' projects from hollow post a, and attached
pivotally thereto by a bolt g, Figure 5, is a swinging arm r.
A post y projects from the upper side of the platen, as seen in Figure 1, and
to said post, and to the side of the aforesaid arm o' on posts a is pivotally attached
a connecting rod v, bolt q passing through its end at arm o³.
Said bolt q has that portion of it which passes through said rod v turned
eccentric to its axis, as seen in Figure 5. A set screw, as shown, is placed in the
end of arm o³, and adapted to be screwed against bolt q to prevent it from
turning.
Connecting rod v is provided with clamp pivot holes, as shown, so that there
may be no lost motion in this connection.
One arm of the bell-crank lever o³ is perforated transversely to receive the end

is an ink roller frame carrier consisting of the semi-tubular longitudinal
part 2 and the parts 3, 4, of like tubular form at right angles to the former, and
having an arm 5 projecting from said part 3, as shown.
The shaft & passes through the tubular portion 2 of the frame carrier =, and the

of shaft a, as shown, and are adapted to receive two posts, 6 and 7, of the ink roller.
frame w, on the upper ends of which are nuts 8, as shown.

page_text: Spiral springs 9 are placed on posts 6 and 7 between the carrier Z and the
frame w.
A bent connecting-rod 10 is pivotally attached to the side of the post a' next to
the platen, and to the end of arm 5 on frame Z.
The ink-rollers 11 are adapted to turn on shafts, which are fitted to proper twin
boxes attached to the frame w, as shown, and are provided with collars near their
ends which roll on tracks 12, running transversely across bed B when the ink-
rollers run off from the type-form.
On the upper-side of the platen near its rear edge are provided two short
posts 13, which are perforated transversely for the reception of the tympan finger-
shaft 14, which is splined longitudinally, as shown, and has a crank 15 formed on
one end thereof, and to the end of said crank is rigidly fixed a bent lever 16, as
shown in Figures 6 and 7.
Pivotally attached to the side of crank 15, as shown in Figure 6, is a rod 17,
provided with adjusting nuts, as shown, and its upper end enters a hole formed
through a projection 18 on the back of the platen. A spring 19 is interposed
between said projection 18 and said nuts on rod 17.
The tympan fingers 20, of which there are two, having collars 21 formed on
their lower ends to fit on shaft 14 and bent in the form shown, are secured on said
shaft by set-screws, whose points enter said spline in said shaft, and said fingers
reach from the shaft under the bottom edge and up in front of the pluten, as seen
in Figures 3 and 7;
-
Fixed to the outer sides of the posts a, a, are two vertical rods 22 adapted to
-support-two-brackets-23,_each_of_which_is_adapted to support a paper-table 24,
pivotally hung on said brackets to one side of their centres.
The operation of the press is as follows, it being understood that the usual-
provision of type-form and ink has been made.
The position of the operating parts of the press, when the platen is up, presenting
its under side or face conveniently for placing the paper to be printed upon it, is
that shown in Figure 3.
Upon pressing upon the foot treadle E shaft h is caused to turn by the action
of the rope or chain g attached to the periphery of the segment f. As said shaft
turns arms d¹, d², are caused to swing downward, drawing rods d connected to the
ends of the platen-shaft e and the platen in the sanie direction.
Immediately that said downward movement begins the platen commences to
turn on its shaft in boxes e', so actuated by the connection of the post y on the
back of the platen, with the fixed arm o on post a of the frame through the
connecting rod v, and while moving down turns so as to bring its face squarely
against the type thereunder, or to the position shown in Figures 1, 2, and 4.
To enable the operator to so adjust the plane of the face of the platen that it
shall perfectly agree with the plane of the type-face, means for slightly swinging
the platen on its shaft while nearly against the type are provided in the bolt q.
connecting one end of the rod v with arm 08. By turning this bolt slightly its
eccentric portion causes rod v to move longitudinally in the direction required to
adjust the platen to the necessary plane, and when so adjusted the bolt may be
secured against turning by the set screw shown on one side of arm o³.
When shaft is turned far enough over to bring the ends of arms d', d², down
to the position relative to the axis of said shaft, which the double crank shape of it
permits before rods & can strike it a very great pressure of the platen upon the
bed is produced as said arms and rods approach a corresponding line, and a powerful
printing impression is the result.
While shaft is revolved, as above stated, springs H are elongated, and upon
lifting the foot from the treadle their retracting power turns said shaft in the
opposite direction, and lifts the platen back to its upward position.
Said springs as heretofore set forth are connected to collars i on rod F, and by

page_text: turning and setting said collars suitably thereon the tension of said springs may be
increased or diminished as may be desired.
When shaft h is revolved to bring the platen down, as above described; the pawl-
rod j is drawn towards the front of the machine, and when said shaft turns back
the end of said rod engages with the ratchet-wheel K, and so turns the ink-table M
partly around spring t, serving to hold the end of the rod against the wheel.
It will be seen that the ink-rollers in Figure 1 are shown in front of the post
a, a', having been brought into that position and across the type-form from the
ink-table as the platen moved up. Figures 1 and 2 show the position of the said
rollers and their actuating parts when the platen is down.
Simultaneously with the downward movement of the platen just described,
occurs the backward movement of the ink-rollers onto the ink-table, actuated by
the swinging of the bell-crank lever o³, caused by the downward movement of
rod o², connecting it with arms d² on shaft h.
The connection of the upper end of the ink-roller frame carrier with post a' by
the connecting rod 10, allows said frame to swing freely below said rod. Frame
obeys the oscillating motions of shafts, the latter being actuated by the movement
of the bell crank lever.
•
Thus each time that the platen goes up, the ink-rollers are carried from the ink-
table across the types between posts a, a, and when it descends they return to said
table, and the springs 9 tend to force the rollers against the type bed sufficiently
to cause the form to be properly inked.
It will be observed that the tympan fingers when the platen is up spring away
from the face of the platen, as shewn in Figures 3 and 7, and they are caused to
move to this position by the striking of lever 16 (Figure 7) against shaft s, when
the platen swings to this position; but as soon as the platen has turned slightly
on its axis said lever is moved away from said shaft, and springs 19, operating to
drive rod 17 downward, shaft 14 is revolved, causing the fingers 20 to quickly
spring against the face of the platen, and hold the paper placed thereon to be
printed.
The paper tables 24, supported on brackets 23 at the ends of the bed, are
provided with pivots placed on their under sides, one side of their centres and said
brackets may be swung backwards, and the tables 24 be swung over the ink table
in such a way that they offer no obstruction to placing a box cover over the whole
upper part of the machine.
This press may be easily converted into a power press by any suitable attach-
ment, whereby shaft H is caused to have a reciprocating rotary motion, such as is
given to it by the treadle and its shaft connections, and by springs II, in which
case those parts may be dispensed with.
By the construction heroin described and shewn, a self inking foot power press
is provided which is simple in construction, one in which an unusually large type
form can be practically printed from, owing to the great power which operates to
force the platen down, and in which the self inking devices are simple and
effective.
