An Improved Apparatus for Feeding from a Reel of Paper to
Printing Machines.
I, GEORGE KEEP, of 151, Leathwaite Road, Wandsworth, London, S.W.,
Printing Machine Manager, 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 is applicable to both perfecting and one sided jobbing printing
cylinder machines which are now being fed by hand labour. Instead of the
continuous feed now used on the ordinary fast newspaper printing machine from
the reel of paper, my invention differs, as it is only required to give off sufficient
paper for the largest size sheet of paper the machine will print, then the feed
stops until the printing cylinder makes a revolution and then the feed commences
again. By altering the throw of a connecting rod on the main shaft of the
printing cylinder by a set screw in the slide of the crank it can be arranged to
print and cut off any smaller sized sheet of paper the printer may require to work.
And in order that my invention may be properly understood and readily carried
into practice I have appended hereto five sheets of drawings to which reference
will now be made and to the letters and figures marked thereon.
A is the connecting rod, connecting N to D N being the crank secured to the
spindle of the driving wheel Q of the printing machine the slot in the crank is to
allow the connecting rod to slide for adjustment of the paper to be given off and
to be printed.
Q-Driving wheel of printing machine.
D-Crank on spindle R.
D has a longer throw than N.
Attached to crank D is a rachet to work the wheel C, and the action of the
crank D is the same as a rachet brace, riz.: as the connecting rod works to and
fro, works the wheel C round.
S-A spur-wheel, with involute teeth, on spindle R, and is geared into a spur-
wheel on roller spindle E.
O is a set screw to alter position of crank N.
P-Printing cylinder.
G-Roller for carrying the paper to the laying-on table, the paper running
between the feed rollers E and F.
J-Double chain wheel, or a pair of chain gearing wheels fastened together,
one is geared by a chain from E to J the other J to I as indicated by the
accompanying drawing.
His geared to F by the same arrangement as J is geared to I. The chains
and chain wheels are the same as is used for bicycles.
K-Weight for balancing the frame if necessary. The frame is fitted with
indiarubber wheels, which cause the reel of paper to revolve, and fall as indicated
on drawing.
M-Reel of paper, and the dotted lines indicates the same passing up to the
laying-on table into the feeding rollers.
E-Set screw to alter position of weight as shown. The arrows indicate the
direction in which the wheels and chains move.
W-Rod connected to knife for cutting the paper.
F2 Geared into H by chain gearing.
A-Tapes running on rollers B and H to carry the paper down to the printing
cylinder.
V-Bearings to carry the spindles or shafting.
027

page_text: D bearings to carry spindle of reel of paper.
2-Disc on shaft of driving wheel.
3-Quadrant.
All rollers and actions can be reversed to attain the same motion and result.
The spindle of paper reel M can revolve between mitre centres (as for instance
in a lathe) to attain greater freedom to revolve.
By altering the connecting rod A, by moving it either way, will alter the length
of paper that will be given off of M, and as all the working parts are connected,
they work simultaneously, and the knife will cut off the paper the required length.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.―
The improved apparatus for feeding from a reel of paper to printing machines,
of the ratchet, eccentric and crank motion on wheel C or their or one of their
mechanical equivalents in combination with the other working parts of said
printing machine operating and working substantially as herein described and
shewn in the accompanying drawings.
Dated this 10th November 1890.
GEORGE KEEP.
