JOHN HENRY RICHARDSON DINSMORE, of Liverpool, in the County of Lancaster,
Bookbinder. " IMPROVEMENTS IN AND APPLICABLE TO MACHINES FOR PRINTING
AND RULING PAPER."
This Invention relates,-
First. To apparatus or appliances for feeding or supplying sheets of paper to
printing and ruling machines. Under this first part of my Invention, I place the
sheets of paper to be fed or supplied to the machine on an inclined table, and cause
such sheets to be removed from the table one at a time by means of excentrically
rotating discs, wheels, or drums, formed of or coated with india-rubber or elastic
material. India-rubber or other elastic stops are provided to prevent more than
one sheet rising at a time. The inclined table is made adjustable to suit various
sizes of sheets, and is caused by means of ratchet, adjustable screw, or like gear to
move towards the discs, wheels, or drums as the sheets of paper are removed there-
from. An india-rubber faced quadrant-shaped adjustable arm is placed in front of
the table on a shaft, which arın rises when in contact with the front sheet as the
said sheet is being drawn from the pile. By throwing the ratchet out of gear the
table is prevented from moving forward too quickly. When the paper allows it
the table falls, the ratchet being brought into gear, and in this way the sheets are
uniformly fed one after another.
Second. This part relates to guides or stops for adjusting sheets of paper in
position before being printed upon or ruled. In carrying this said second part of
my Invention into practice I cause the sheets of paper to be carried one after the
other from the delivery table between endless travelling threads or tapes, or a
blanket or cloth, or both, to a transverse stop piece which is caused to rise at the
desired time, and thereby arrests the motion of each sheet of paper for a sufficient
time to allow of the leading edge of said sheet being adjusted transversely against
the said stop by the action of the continuously travelling threads or tapes and
blanket or cloth. The said stop whilst (or after) the sheet has been adjusted trans-
versely as regards its leading edge is caused to travel in a direction at right angles

page_text: to the motion of the endless threads or tapes and blanket or cloth; this causes the
said sheet to adjust itself as regards one of its side edges against an adjustable stop
placed longitudinally. The said transverse stop is then caused to fall, and the
motion of the endless threads or tapes and blanket or cloth carries the said sheet
into the printing or ruling table; the above operation is repeated for each sheet.
Cam, eccentric, or other suitable gearing is employed to give the required motion
to the transverse stop. To cause the endless blanket or cloth to move truly, I. affix
thereto near each edge a band of leather or other suitable material, and form in the
carrying rollers recesses or grooves to receive the said bands.
Third. This has reference to apparatus or appliances for delivering sheets from
printing or ruling machines. In practice I employ a series of flexible travelling
tables, each table being formed by cloth or tapes stretched on transverse rods and
connected together. by means of endless bands, belts, or chains, and give a
continuous travelling motion to such tables. Each table receives a printed or ruled
sheet from the printing or ruling table and carries it forward until such sheet
comes over a receiving table; the said sheet is then arrested in its motion by a
transverse stop which rests on the cloth of the table or projects downwards
between the tapes of which the table may be composed. The said travelling table
continues its motion and leaves the sheet behind to drop on a wooden receiving
table.
Fourth. The fourth part relates to apparatus or appliances for raising ruling pens
from off the and causing them again to rest on the surface of the paper to be ruled.
In carrying this part of my Invention into effect I employ a disc caused to rotate
on a shaft. On the said disc are placed two, adjustable, rings or collars, between
each of which and projecting from the periphery thereof are placed and fastened at
suitable distances, according to pattern required, strikers formed of small pieces of
iron or
steel which act on the arm from the pen frame so as to raise the pens from
the paper at any desired time, a catch or its equivalent retaining the pens in
position when once raised. Each alternate striker serves to release the catch at the
desired time so as to allow the pens to descend. The apparatus or appliances above
described receive motion and are driven and geared together in any desired or
suitable manner.
