GENERAL DESCRIPTION.
In my patent for improvements in presses for printing and embossing dated
January 1. 1879 No. 14 as also in my former Patents for printing presses I show a
platen supported upon curved rockers and a spring link connection for controlling
the rocking motion of the platen, the curve of the rockers extending considerably
below the lower edge of the platen-This was necessary in order to have the
movement of the platen correspond with those of the impression cranks which
formed a part of the driving gear wheel and crank-wheel-In Fig. 5 of the present
case the crank pin G is shown as forming a part of the shaft of the impression
wheels or positioned within the circumference of the shaft and this allows the
rockers of the platen to be made much smaller and rocker seat N. fig: 7 is brought
above the line of the lower edge of the platen-With this construction the platen
is less liable to inaccuracy in its direct impression movement In the former patents
referred to the link which controls the movement of the platen is provided with a
spring or springs for holding the platen steady in its rocking movement.
In fig: 7 of the present case the link is provided with a lug as R. which follows
the curve of the cam S during the rocking movement of the platen and passes
under the horizontal face of the cam block during the direct movement of the
platen D. This device controls the movement of the platen without the use of a
spring
These
In my patent of 1879 an upright steam chest is shown for heating dies-Fig: 3
of the present case shews an improved construction of the chest. The body of the
chest A is made in two parts which have serpentine grooves in their face.
grooves are of sufficient capacity to take in loosely a bent steam pipe, the body of
the chest forming a Jacket for the pipe-The material of the two parts of the
Jacket which lies between the lines of the zig-zag pipe come together and form a
firm support for the impression-The advantages of this construction are:-first,
steam may be used at a much higher pressure without danger of leakage; no
packing is required; the pipe may at any time be easily renewed; and the body of
the chest is not liable to injury from rust.
In my patent of 1879 the impression gear which is shewn and described as having
a reinforcing segment cast on or attached to that portion of the wheel which takes
the strain of the impression-Fig: 5 of the present case shews a segment of steel B.
welded into the cast iron wheel at the time of casting-This allows the wheel to
be of an even thickness all round if desirable, and avoids extra fitting.
In my Patent of 1879 the impression adjusting sleeves for both sides of the Press
are shewn as locked in position by a single latch holding the adjuster bar to the
bridge of the platen.
In Fig 4 of the present case two latches g. g¹ are used one for each side of the
press for holding the adjuster sleeves E. E. more firmly in position.-These may be
latched to the Bridge as in the former case, but are shown in Fig: 4 latched to the
drawbar c. c-The advantage of this construction is the reduction of friction on

page_text: the sleeves as the sleeves move in unison with the drawbar during the impression―
The springs e, e at each end of the adjuster-bar F hold the latches engaged the
entire bar being raised to free the latches to throw off the impression.
To change the degree of impression the slides of the latches are moved upon the
arc of the eye of the drawbars to corresponding positions and each being then made.
fast with a bolt.
In Figs 2 and 11., two impression gears are shewn one for each side of the press,
and a pinion for each on the main driving shaft-both of these gear wheels are let
into the framework behind the face of the bed. In presses requiring a very powerful
impression, I also use two fly-wheels J. J. to avoid springing in the pinion shaft
and bearing as they act upon the impression gears at the extremes of the main
impression shaft
In the press as formerly patented I use soft composition distributing rollers on
metallic distributing cylinders, and metallic lateral change-distributors-These
lateral distributors I made of a shaft prevented from turning and a metallic
revolving sleeve having lateral motion on the shaft The lateral movement of the
sleeve was produced by an ordinary cross thread screw movement with crescent.
In the present case I show in Fig: 9 the shaft c². having a number of cross thread
screws of different lengths.-By using this shaft different distances of movement
may be given to the sleeve by changing the crescent of the sleeve from one screw
to another
In Fig 9 are also shewn 62 adjustable rings as K K. made fast to the sleeve
which sleeve has lateral motion on shaft m. These rings are made to correspond to
the measure of different lines of type taking into account the movement of the sleeve
and are for use in work of several colors done by the press at a single impression.
By using a number of such lateral distributions baving different distances of lateral
movement and rings to correspond as a² and be a great variety of work in bands
or lines of color can be done by applying the ink of different colors to the rings of
the changers and without necessarily changing any other parts of the press-A
modification of construction is shown at d³, e in which short adjustable sleeves are
brought to position on the shaft and made fast, the short sleeve having a sinuous
or diagonal groove therein-A moveable ring on the sleeve is provided with a pin
or traveller which works in the groove of the sleeve and gives lateral movement to
the ring-In this way a number of rings differing in width and distance of lateral
movement may be placed on a single shaft. If the rings are very narrow in order
to prevent cramping in their movement, I make the groove in the short sleeve 1³.
sinuous having three curves to the right and three to the left and use three pins in
the ring as ³ In making up the lateral distributor e² other short sleeves or
washers are shown-These are made to correspond with measures of different
kinds of type and aid in making up the distributor to correspond with any other
form of type-These lateral changes may be prepared for any color-job while the
press is being used for other work-The rings and washers may be cheaply made
by casting them from type metal or hard Britannia-The arrangement of
distributing rollers y, distributing cylinder T³. and lateral changers a³. 62 is shewn
in Fig: 10.
ns
To prepare the ink-fountain to correspond with the lateral changers to supply
the several colors of ink I use dividing adjustable partitions M Fig: 8. Movable
partitions for dividing an ink-fountain into apartments are common but
ordinarily constructed are defective as they allow mingling of the ink when the
fountain blade is lowered to increase the feed-To avoid this I construct the
partitions as shown in Fig: 8 The curve of the partition M is made to fit
the curve of the fountain roller W and a clamp is constructed at the opposite end
of the partition which by means of screws fp make the partition fast to the
fountain after being placed in the position with its curve nicely fitting the fountain
roller A deep groove his cut into the under edge of the partition M and a
movable wedge shaped slide p placed in the groove. When the fountain blade O is
lowered to increase the feed of ink a space would be left under the base of the

page_text: partition and cause a mingling of the inks in different compartments were it not
for the wedge shaped slide which being thrust forward as the blade is lowered fills
the space and keeps the division of color perfect-This color apparatus both as to
the lateral changers and fountain partitions is applicable both to platen and
cylinder presses and I do not wish to limit my patent as to its use to either
It is often desirable or necessary in printing, and also in embossing to skip one
or a number of the ordinary impression movements of the press to prepare the
work for the next impression while the heavy fly wheel and most of the machinery
of the press must of necessity be kept in motion-This is easily accomplished in
toggle presses by simply throwing out the impression toggle after each impression
until the impression is again required, but in presses having impression cranks or
continuously moving impression apparatus the skip is difficult to make
In Fig. 11 I show a device for a stop motion which is both positive and safe in
its action-The heavy fly-wheel J. is loose on the driving shaft and is revolved
constantly by means of driving belt a³ The part of clutch es slides on a spline
in the shaft and is thrown in and out of connection with the hub of the
fly wheel J by means of the automatic shifter f³. The automatic shifter is
constructed and operates as follows:-a gear wheel 9 driven by the driving shaft
by means of a pinion is constructed to require the same number of turns of the
driving shaft for a single revolution of the wheel as the impression crank-wheel B.
On the end of the driving shaft is a tight and a loose pulley run by means of a
belt b This belt has a shifter having an automatic throw off movement-The
movement for throwing on this belt produced by means of the foot lever H' or
other convenient device for the operator; or it may be made to act automatically
at stated intervals from the motion of belt 65 if desirable-The gear wheel g³ has
on it three shifting cams a7, n°., m³,-When the belt 65 is shifted from loose
pulley do to tight pulley c³ the driving shaft starts the impression wheels B. B
in motion, and when reaching their proper speed just before the time of the
impression nip the cam no operates shifter f³ connects the driving shaft and
fly-wheel by means of the clutch, and the heavy fly-wheel carries the press over the
powerful impression-As at the same time the clutch is moved the shaft and
Hy wheel are turning at or about equal velocity no stroke is made but the entire
machinery moves steadily without jar-As soon as the impression is passed the
cam m³ throws out the clutch and the power of the belt 65 alone brings the platen
of the press to its position for receiving the nest sheet-when cam a' shifts the
belt to the loose pulley and leaves impression wheels and platen again at a
stand-still in which condition they remain until it is desirable to produce another
impression, which may be done by shifting the belt 65 again on to the tight
pulley c³.
To secure the turning of the distributing rollers, while the wheels B. B. are at
rest I connect the distributing cylinder with the fly wheel J¹. by means of belt x
and as the flywheel is in constant motion the distribution of ink goes on without
interruption
The stop motion of Fig: 11 is applicable not only to printing presses and
embossing presses but also to other power presses stamping machines, cutting
machines &. and I do not wish to limit myself in its use-In using the stop motion
as described with the press the platen rest of my patent of 1879 previously referred
to is not needed; and the impression cranks therefore needing much less throw are
drawn in toward the centre of motion and are made to form a part of the
impression shaft.
