Feeding of Sheets of Paper to Printing and like Machines.
I, FREDERICK WILLIAM VICKERY, of 14, Newcastle Street, Farringdon Street,
City of London, Ruling Machine Maker, do hereby declare the nature of my
said invention to be as follows;-
-
This invention has for object automatically feeding sheets of paper in printing
and like machines.
To carry this invention into practice, say if fitted to a single cylinder printing
machine, I attach a weighted cord or strap to the reciprocating table, this cord
or strap I wrap round a grooved roller or wheel whose circumference is equal to
or about that of the distance the table has to travel.
The boss of the wheel is in connection by spring and clutch pawl so that it
turns actively in one direction only.
The axle of the wheel carries a drum on which a sheet or a series of strips of
cellular faced fabric, is secured by one end only, the other end being free to fall
over the drum for flopping down upon the paper to be fed, and then to be drawn
under and around the drum; the cellular faced fabric by its suctional action on
many points of the paper retaining its hold and drawing the top sheet away
from the pile, thereby feeding the paper on and releasing itself gradually as it
rises, so that by the time the fabric has passed its tail end under the vertical
axial line of the drum, the sheet of paper has been delivered on to the feed
board, or on to endless conveying cords, with its fore end against the stops ready
for the grippers to engage and take it away to be printed.
The action of the drum is intermittent but always in the same direction, and
as the wrap of cellular faced fabric arrives at the top of the drum it slides off and
flops down upon the top sheet of the pile, and awaits the active rotative motion
of the drum to draw the existing top sheet from the pile and pass it to the cylin-
der grippers, as before explained, and so on for each successive sheet.
If a second or next under sheet be shifted with the top one, it would be stopped
by a roughened edging over which it would have to pass.

I, FREDERICK WILLIAM VICKERY, of 14, Newcastle Street, Farringdon Street,
City of London, Ruling Machine Maker, 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 has for object, automatically feeding sheets of paper in printing
and like machines.
My invention will be clearly understood by reference to the annexed drawings.
Figure 1 side elevation, and Figure 2 plan of a portion of a single cylinder
printing machine with the table thrown outwardly and with the cellular faced flop
Hap down upon the top sheet of a pile of paper ready for its removal.
Figure 3 plan of parts with the table thrown inwardly and a sheet of paper in
position for removal for the printing operation, the cellular faced flop flap being
upon the drum and awaiting the next rotation of the drum for flopping forward
the next top sheet of paper from the pile.
A, frame of machine.
B, cylinder. C, reciprocating table. D, lug on under-
side having cord or strap E attached. F, guide pulley. G, grooved pulley
around which strap E is wrapped and secured.
H, boss on pulley G mounted loosely on shaft I. J, ratchet teeth on boss.
K, clutch teeth on fixed collar of shaft I. L, spring encircling shaft I and press-
ing against boss H to ensure engagement of ratchet teeth J.
M, resistance weight on free end of strap E. N, drum on shaft I. P, cellular
faced fabric as a flop flap secured at one end in drum N, the other end being free
to fall onto the top sheet of the pile of paper Q at each revolution of said drum N.
R, R, endless cords for receiving each sheet of paper in succession. S, S, sup-
porting shafts of cords R, R, said cords R, R, being adjusted at an angle to carry the
paper sideways against the " side lay" T and in contact with stops U ready for
the "gripper" of the cylinder B to remove as they come round for the purpose.
V roughened rib to prevent the lower of two sheets being carried on by the
cellular faced flop flap P should, from any cause, two sheets be moved as one from
the pile Q.
In operating this cellular faced flop flap P it is essential that the level of the
pile of paper Q be maintained for proper feed purposes, and to effect this I hinge
the table top W to the back frame X and allow the opposite end to rest upon a
lever which with the counterweight Z effects the rising of the free end of the
table top Was the pile is reduced.
The action is as follows;-A ream or other quantity of paper is placed upon the
table top and the weight M is adjusted on the lever Y for the front end of the
top sheet to be level with the entry between the bottom of the drum N and the
roughened rib Y. On the drum N being rotated by the rack a and its pinion b
during the back travel of the reciprocating table C, the cord E slackens and the
weight M causes the pulley G to turn for its teeth J to slide over the teeth K of
the otherwise fixed shaft I.
On the reverse travel of the reciprocating table C the ratchet teeth J, K, engage
and the pull of the cord E causes the pulley G to rotate and also the drum N,
this carries the cellular faced flop flap P over to fall on to the top sheet of paper
on the pile Q and then to draw the top sheet away, passing it over the roughened
rib V and delivering it on to the endless cords R, the cellular faced flop flap P

page_text: coiling itself upon the drum N ready for the next fall and suctional gathering of
the succeeding top sheet, the first sheet being simultaneously removed by the
grippers of the cylinder B for the printing operation and during which the
second sheet has been passed on to the endless cords R in the manner already
explained, there being always a sheet of paper in reserve and bearing against the
stops U for the purpose of collection by the grippers.
The speed of the endless cords R can be regulated by cords c from an overhead
pulley or otherwise.
:
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. The means and appliances for automatically feeding sheets of paper to print-
ing and like machines, as herein before described and arranged substantially as
indicated on the annexed drawings.
2. The slip and feed action of drum N from the reciprocating table C of a
machine, in or to which a cellular faced flop flap P is arranged and so mounted as
to wrap upon said drum and to suddenly fall for suctional grip and then to move
the top sheet from a pile of paper, as and for the purposes set forth and substan-
tially by the means illustrated on the annexed drawings.
