Improvements in Job Printing Presses.
I, HENRY JOHNSON, of, 202. Fulton Street, City, County, and State of New
York, United States of America, Manufacturer and Merchant, 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.:-
My invention relates to improvements in job printing presses in which both the
bed and the platen are movable and, with the other parts of the printing press, have,
heretofore been constructed to be operated by a singlo treadle and foot used to
"kick" the press-that is, to operate it by one foot resting upon a single treadle
connected with a motor shaft provided with one crank, and which also have, for ink
distributing purposes, been constructed with an annular plate and a circular plate
located within the annular plate, the annular and the circular plates being given
opposite motions for the purpose of distributing the ink taken from'the' duct roller;
by one or more of the form rollers, and. first distributed upon the annular and
circular plates combined, and then distributed therefrom or applied upon the form,
held in a movable bed, at the time when the movable bed is in motion; the
platen of the press being also movable and being given such motion that its face
will be turned up nearly flat or horizontal to receive and register the sheets to be
printed.
My invention also relates to improvements in mechanism for distributing ink,
attached to and operated by the mechanism of the press described.
"
My invention is an improved, double treadle, alternating and bipedal, or ambi-
pedal, job printing press, and the objects of my improvements are to provide means
for the better, easier, and more rapid operating of the press by 'means of a double
treadle,' or pair of treadles, one for each foot and leg, double treadle-hooks and
double cranks on the crank-shaft, improved ink feed and distribution from an ink
fountain through a duct, two distributing rollere, a cylinder, a carriage roller, a
revolving plate and form rollers, upon a form in a movable bed, an adjustable seat
and seat support for the double treadle and ambipedal operator, or press feeder,
preferably connected with the press, and a movable or adjustable feedboard or rest
against which the operator may lean in order the better to steady himself for the
purposes of operating and controlling the two treadles, alternately, one by each foot,
and also for the purpose of more rapidly and accurately feeding and registering the
sheets upon the platen and delivering the same.
A further object is to distribute the ink to better advantage and more
completely before it is applied to the revolving disk of the press shown 'and
Jescribed:
I attain these objects by the mechanism illustrated in the accompanying drawing,
n which
Figures 1 and 2 are part side and part sectional views of the entire press.
Fig. 3 is a top view of the treadles, seat, double crank-shaft and balance or pulley
wheel:
Fig. 4 is a detail front view of the seat, seat supports and the adjacent parts of
he press frame.
Fig. 5 is a top view of a slide table rest,, and Figs. 6, 7, 8 and 9 are detail views
f the adjustable table or slide rest arrangements.
Similar letters refer to similar parts throughout.the several views.
F is the frame of the press. 'B' is the balance wheel: P is the movable platen,

page_text: moving on the shaft or journal P. At the moment of feeding, the platen surface
lies nearly flat, as shown in full lines Fig. 2, and dotted lines Fig. 1. C is the cam.
shaft from and by which the platen P, the bed B' and its frame F', as well as the
roller carriage and brace E are operated. C 2 is the driving-shaft of the press,
provided with double cranks N N. B2 is the seat bracket, which at its lower end,
as shown, is made in the form of the letter T, and is removably but centrally
engagable with and supported by a central part of the frane F, at a central opening
therein, as shown in Figs. 1, 2 and 4. At its upper and outer end the seat bracket
has a socket for an adjustable rod R carrying an adjustable seat S.
TT are the two treadles, connected to the pair of cranks N N by the pair of
treadle-hooks O O.
The seat bracket B2 should be located in the center of the cross frame of the
frame F, or between the treadles, in order to hold the "feeder" or operator in
proper relations to the treadles TT to enable him to run the press properly and
easily by bipedal or alternating ambipedal action.
The crank or driving shaft C 2 is provided with a pinion G which engages the
large cogwheel G" secured on the cam-shaft C. T is the feed board provided with
the adjustable rest R', against which the seated feeder or operator leans in order
to steady himself for the purpose of gaining proper control over the treadles and
over his hands so that he may feed, register and deliver properly.
Kis a foot support, for each foot, one on each side, secured in or on the seat-
bracket B 2, upon which either foot may be placed to obtain rest while the press is
alternately kicked" by the other foot; or both feet may be placed there, leaving
the treadles free to run if in motion. Consequently the press may be alternately
kicked by either foot,.or run by both feet, or be left free, much to the relief of the
operator and feeder while he is resting his feet and legs.
The feedboard and adjustable steady rest R' is made adjustable in order to
accommodate operators or feeders of different sizes and lengths of arm, and in different
positions, and to thereby enable them to steady themselves and with both hands to
feed, register and deliver more rapidly and accurately, while using both legs in
operating the press. The seat and the scat rod are made adjustable for similar
purposes, not only in relation to each other, but also in relation to the treadles and
to the steady rest. The seat becomes in fact a new fulcrum from, which the press
is operated that is, run, fed, registered to and delivered by the feeder, replacing
the floor. This seat fulcrum is not only preferably attached to the frame so as to
become a new, related and integral part of the press, but as a fulcrum is related to
all parts of the press as one of the efficient elements of its operation and different
functions. The feedboard and steady rest become a sort of secondary fulcrum
co-operating with the seat to give the feeder entire control of the press and all its
functions.
The fountain is, secured to, carried upon and moved with the bed-frame F, and
therefore is changed as to its levels and angles of relation to the other parts of the
press, and requires to be adjusted thereto in order to give a proper How and
distribution of ink.
M is the fountain. M' the duct roller, which is operated by the ratchet lever L
and transfers the ink from the fountain to the distributing roller M 2, from
which it is trausferred to, upon and with the cylinder M 3, to be taken therefrom
and further distributed on the upper carriage frame roller M 4, to be thence and
thereby distributed upon the distributing disk or plate M5 and by the form
rollers M 6 and M 7, and by these last upon the form in the movable bed at last.
The revolving plate M 5 is operated in the usual way.
The plate M 5 is a single plate-that is to say, it is not made up of an annular
plate with a disk fitted in the open center of the annular plate, as in the Gordon
press. Consequently the whole of the distributing plate surface revolves in one
direction instead of opposite directions, as is the case with annular and disk portions
of the Gordon distributing plate, and the distribution of the ink is greatly improved
thereby.

page_text: The bed containing the form is not only movable on, with and by the bed
frame F, but is in motion during the entire process of taking the ink from the
fountain, distributing it upon the cylinder M 3, upon the plate M 5 and also upon
the form. The double treadles operate all these moving parts, and the driving
force being more steadily applied there is less shake in the action of the press and
consequently a more even distribution of the ink.
The duct roller M" is operated in the usual automatic way by the motion of the
press and is held in fixed bearings. The rollers M 2 and M 3 are operated, at the
time of taking ink from the fountain, by the roller M', and the ink passes.
from M to M 2 and thence to M3 through the contacts shown in Fig. 2..
But M 2 and M3 are held in slotted bearings and can be and are lifted by the
upper carriage roller M-4 so that the roller M 2 is not in contact with the roller M',
being lifted and held by M3 and M. 4. When so raised, the upper carriage roller
takes the rollers M 2 and M3 in charge, revolves both of them and distributes and.
transfers the ink to the upper carriage roller and thence to the revolving disk with
which this last roller is at the time in contact. Thus the rollers M 2 and M 3 are-
subjected to two different sets of transferring and distributing operations, in
succession, at overy vibration of the bed frame F. The movement of the bed
frame which carries the inking devices,assists in producing a proper transfer and
distribution of the ink. It is an advantage to have the ink taken from the
Froller M when the bed frame F is in its extreme rearward position. At that
part of its motion the roller M 2 rests more securely upon the roller M¹ and
therefore takes the ink in a more uniform thickness or quantity. The carriage
rollers take the ink from the revolving disk and transfer it to the form in the usual.
way, but in a complete or perfect state of distribution for high class work, such as
tint and half tone work.
