I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co. Patent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature of
this invention to be as follows:-
This invention relates to printing machines or presses of the class known as job
printing presses and more particularly to the job printing press for which Letters
Patent of the United States of America were granted to Fred O. Degener April 24th
1860 and in which a rocking platen and a rocking bed are about centrally connected
and are brought together that an impression may be given.
One part of the said invention comprises improved means for enabling the operator
to prevent the impression when desired in order to avoid a waste of material, either
paper or card, by improperly placing the same upon the platen of the machine and
which from such improper placing is rendered useless; and to impart the desired
quantity of ink to a large job, more particularly a colour or tint job by allowing the
inking roller to pass any desired or required number of times over the form of type.
The second part of my invention comprises improvements in the construction of
griper mechanism to be used in connection with such machines in order that the
gripers can be depressed upon the platen of the machine while the same is in the
horizontal or open position thus enabling the said gripers to be adjusted by
the operator to an impression made upon the tympan sheet. Heretofore in the
construction of the particular press hereinbefore referred to, the griper mechanism
has been attached to the lower end of the rocking bed, and after an impression has
been taken upon the tympan sheet, and the bed and platen have been rocked down
until they had assumed nearly the position necessary for the production of an
impression, the gripers employed have been adjusted by the operator to the impression
upon the tympan sheet by moving them along the frame supporting them.
Necessarily the operation was one requiring care and occupying considerable time.
This part of my improvements permits the operator to adjust the gripers when the
platen is in the horizontal position thus enabling him to do this more expeditiously
and with less care than was heretofore required.
The frame for supporting the operative parts of the machine the bed upon which
the form of types is placed the disc upon which is distributed the ink to be imparted
to the rollers, and the roller sockets or supports are of ordinary construction.
In order to regulate the position of the platen relatively to the bed, screws are
passed through the auxiliary frame supporting the said platen,

page_text: The beam of the auxiliary frame directly behind the platen is bored to receive a
shaft free to turn in the same when desired. This shaft is provided at each end with
eccentric studs to which are connected the forward ends of two connecting arms the
rear ends of which are attached to a shaft having its bearing in the main frame.
The auxiliary platen frame is slotted to allow the lower portion of a handle to pass
through it and be fastened in position upon the said shaft. The interior of this
handle is provided with a rod having at its lower end a stop, over which rod is passed
a spiral spring.
When the form requires more inking than would be given to it if the bed were
passed once or twice beneath these rollers or in order to suspend the impression or
prevent the platen being moved sufficiently forward to admit of the contact of the
paper with the type the said handle is grasped and turned down or back from the
vertical or nearly vertical position to an inclined position by which movement the said
shaft is turned and the extent of movement of the platen and of the connecting arms
shortened.
The handle can be turned down sufficiently to govern the degree to which the shaft
should be turned to accomplish the desired result, the slot being made of the proper
length for this purpose and the rod provided with the spiral spring which, as the
handle is grasped by the operator and turned, is compressed, and when the operator
releases the handle, expands and throws down the stop into its position, in which it
remains until necessary to manipulate it again the stop having its bearing upon the
side (so to speak) on the beam at either end of the slot.
The means herein before described to suspend the impression are simple, effective
and within easy reach of the operator, (whose position is in front of the machine to
feed it) are easily operated and the cost of constructing the machine employing them
is not materially increased.
In carrying the second part of my invention into practice ears are attached at the
base of the rocking platen at each end of the same, in which ears the griper frame
is hung.
The gripers are held upon such frame by bolts and nuts and are capable of
adjustment to the extent of slots, in the same.
Upon one side of the griper frame I provide a weighted extension carrying at its
forward end a stud and. roller. This roller is free to move upon a surface cam
attached upon one of the bolts employed to connect the rocking bed and the
rocking platen together, and so shaped that as the bed and platen are drawn together
for the production of an impression the gripers will be depressed upon the platen and
have their bearing upon the margins of the sheet to be printed and serve to relieve it
from the form or types employed in the printing.
Such being the construction it will be observed that after an impression has been
printed upon the tympan sheet and the platen rocked back to the horizontal position,
the gripers can be depressed by the operator on the platen by bearing down upon the
same, the frame supporting them swinging freely in the ears in whch it is hung and
the gripers adjusted to the impression upon the tympan sheet by moving them in the
slots in the frame. After the gripers have been secured upon the frame by the bolts
and nuts, the weighted connection will cause the frame to return to its normal position
In the operation of the machine in printing, as the bed and platen are brought
together, the weighted connection, carrying at its forward end the stud and roller, is
guided by the surface cam already described, and the gripers are at the proper time
depressed upon the margin of the sheet to be printed and lying upon the platen
The printed sheet is thus relieved from the form or types secured upon the bed.

page_text: Improvements in Printing Machines or Presses.
1, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co Patent Agents,
Southampton Buildings, in the County of Middlesex, 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 printing machines or presses of the class known as job
printing presses, and more particularly to the job printing press for which Letters
Patent of the United States of America were granted to Fred O. Degener April 24,
1860 and in which a rocking platen and a rocking bed are about centrally connected
and are brought together that an impression may be given.
One part of the said invention comprises improved ineans for enabling the operator
to prevent the impression when desired in order to avoid a waste of material, either
paper or card by improperly placing the same upon the platen of the machine and
which from such improper placing is rendered useless; and to impart the desired
quantity of ink to a large job, more particularly a color or tint job by allowing the
inking roller to pass any desired or required number of times over the form or type.
The second part of my invention comprises improvements in the construction of
griper mechanism to be used in connection with the machines hereinbefore referred to
in order that the gripers can be depressed upon the platen of the machine while the
same is in the horizontal or open position thus enabling the said gripers to be adjusted
by the operator to an impression made upon the tympan sheet. Heretofore in the
construction of the particular press herein before referred to the griper mechanism has
been attached to the lower end of the rocking bed, and after an impression has been
taken upon the tympan sheet, and the bed and platen have been rocked down until
they had assumed nearly the position necessary for the production of an impression,
the gripers employed have been adjusted by the operator to the impression upon the
tympan sheet by moving them along the frame supporting them.
Necessarily the operation was one requiring care and occupying considerable time.
This part of my improvement permits the operator to adjust the gripers when the
platen is in the horizontal position thus enabling him to do this more expeditiously
and with less care than was heretofore required."
In the accompanying drawings.
Figure 1 is a side sectional view of a job printing press to which my improvement
has been applied.
Figure 2 is a top view of the bed platen and their connections the impression being
suspended.
Figure 3 is a sectional view of the platen and means for suspending the impression.
Figure 4 is a view of the means for suspending the impression.
Figure 5 is a view of my improved griper mechanism applied to the press, the bed
and platen being shown in the horizontal position and the gripers depressed upon the
platen.

page_text: Figure 6 is a view of the bed and platen in the horizontal position and the gripers
elevated.
Figure 7 is a view of the bed and platen brought together for the purpose of giving
an impression and showing the position of the griper mechanism.
In the drawing like parts are designated by like letters of reference.
A is the frame for supporting the operative parts of the machine; B the bed upon
which the form of types is placed; D the disc upon which is distributed the ink to
be imparted to the rollers and E the roller sockets or supports.
F is the platen frame supporting the platen G. Through this frame Fand entering
into the platen G to regulate its position for printing relatively to the bed B are passed
the screws H.
The frame F, directly behind the platen G, is bored to receive a shaft I free to turn
when desired. This shaft I is provided at each end with the eccentric studs J to which
are connected the forward ends of two connecting arms K, the rear ends of which are
attached to shaft L having its bearing in the frame A and through which motion is
communicated to the platen.
The platen frame is slotted as at f to allow a rod i to be passed through the frame F
and be fastened in position upon the said shaft i. The handle M is passed over the
rod to slide thereon, and has at its lower end a stop h adapted to engage with
notches at the sides of the opening f. Over the rod i is passed a spiral spring g,
which at its upper end bears against a collar i secured to the rod i and at its lower
end against a collar secured in the lower portion of the handle by a set screw.
The operation of this part of my invention will be readily understood. When
necessary to suspend the impression or prevent the platen being moved sufficiently
forward to admit of such contact either from misplacement upon the platen of the
paper or card to be printed (by contact with the same of the type secured upon the
bed B and inked as the bed is passed beneath the inking rollers placed in the sockets
or supports E) or when the form requires more inking than would be given to it if
the bed were passed once or twice beneath these rollers, the handle M attached to the
shaft I is grasped by the hand of the operator and lifted to release the catch / from
the notches The handle M is then turned down or back from the vertical or
nearly vertical position shown in Figure 3 to the position shown in figure 4. By
this movement the shaft I is turned, and the extent of movement of the platen G and
of the connecting arms K shortened to a sufficient extent to prevent contact of the
type secured upon the bed B, of the press with the paper or card placed upon the
platen G.
The handle M can be turned down sufficiently to govern the degree to which the
shaft I should be turned to accomplish the desired result, the slot being made of the
proper length for this purpose. As the handle M is grasped by the operator and
raised, the spiral spring g is compressed, and, when the operator releases the handle
the spring expands and throws down the stop h into its position, in which it remains
until necessary to manipulate it again, the stop having its bearing upon the side (so
to speak) on the frame F at either end of the slot f.
It will be observed that the means hereinbefore described to suspend the impression
are simple, effective and within easy reach of the operator, (whose position is in front
of the machine to feed it) and are easily operated, and that the cost of constructing
the machine employing them is not materially increased.
In carrying the second part of my invention into practice ears N Figure 5 are
attached at the base of the rocking platen G at each end of the same in which ears
the griper frame O is hung.
P are the gripers held upon such frame by the bolts and nuts p and capable of
adjustment to the extent of the slots q in the same.
Upon one side of the griper frame OI provide a weighted extension Q carrying at
its forward end a stud and roller R. This roller is free to move upon a surface cam S
attached upon one of the bolts T employed to connect the rocking bed B and the
rocking platen G together, and so shaped that as the bed and platen are drawn
together for the production of an impression the gripers will be depressed upon the

page_text: platen and have their bearing upon the margins of the sheet to be printed and serve
to relieve it from the form or types employed in the printing.
Such being the construction it will be observed that after an impression has been
printed upon the tympan sheet and the platen rocked back to the horizontal position,
the gripers can be depressed by the operator on the platen by bearing down upon the
same, the frame supporting them swinging freely in the ears in which it is hung and
the gripers adjusted to the impression upon the tympan sheet by moving them in the
slots in the frame. After the gripers have been secured upon the frame by the bolts
and nuts the weighted connection will cause the frame to return to its normal position
as shown in Figure 6 of the drawing.
In the operation of the machine in printing as the bed and platen are brought
together, the weighted connection carrying at its forward end the stud and roller is
guided by the surface cam already described, and the gripers are at the proper time
depressed upon the margin of the sheet to be printed and lying upon the platen. The
printed sheet is thus relieved from the form or type secured upon the bed.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed as communicated to me by my
foreign correspondent I declare that what I claim is
First In a printing press in which a rocking platen and a rocking bed connected
about centrally are employed, the combination of a shaft I provided with the eccentric
studs J, the slotted platen frame F, the connecting arms K, the shaft L and the
handle M constructed and operating substantially as, and for the purpose, set forth.
Second The combination of the platen frame F, the platen G, the shaft I provided
with the eccentric studs J, the connecting arms K, the shaft L, and the handle M
provided with a rod i, stop h and spiral spring g, substantially as and for the purpose,
set forth.
Third In a printing machine provided with a rocking platen and a rocking bed
hinged about centrally, the combination of a griper frame O free to swing in the
ears N and provided with a weighted extension Q carrying a stud and roller R, the
gripers P and the surface cam S constructed and operating substantially as, and for
the purpose set forth.
