An Improved Delivery Apparatus for Printing Machines.
1
I, WILLIAM PANTER, of 69 Edward Road, Penge, in the County of Surrey,
Printer, do hereby declare the nature of this invention to be as follows
-
This invention has reference to that class of printing machines which print upon
separate sheets. In these machines it has been usual that the sheets as they issue
from the delivery rollers of the machine after printing, should be received by a boy,
and by him laid in a pile; or in some cases an appliance called a "flyer" has been
used for this purpose.
In my improved apparatus, I so construct the delivery rollers, that instead of the
sheets issuing from these flat, they are corrugated or bent into ridges & furrows
running parallel to the line in which the sheets are moving. By this means the
sheets are given sufficient stiffness to permit of their being pushed over the surface
of the pile of sheets by the action of the delivery rollers without the leading end
doubling under, as in the case where sheets are delivered flat in the ordinary way.
To effect this I construct the delivery rollers, which at present are made of uniform
diameter, with bosses or small discs of greater diameter than the body of the roller,
so arranged that each boss on the upper roller works opposite to an interval between
two such bosses on the lower roller. These bosses are capable of adjustment along
the length of the rollers to suit sheets of varying width, and may be covered with
india rubber or otherwise.

An Improved Delivery Apparatus for Printing Machines.
WILLIAM PANTER 69 Edward Road Penge, Surrey, Printer. I 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 :-
66
This invention refers to an apparatus for delivering or taking off" sheets from
printing and other similar machines printing one or more separate sheets and is
designed to do away with the necessity for manual labour in taking off such sheets
after passing through the printing or other machine as the sheets become self delivering by
the use of this apparatus. It is applicable for printing, ruling, hot rolling, bronzing,
varnishing and gumming machines or any other similar machines where sheets of
paper or other material are passed into a machine for undergoing a process and
which now require manual labour for delivering or taking off the sheets as they leave
the machine.
The main point of the invention is that the apparatus makes ridges, furrows, or
bends in the paper or other material and enabling the air to get underneath and
support the same it renders the paper or other material stiff and secures its being
delivered by the apparatus into the position or place desired without doubling up or
under and without manual labour.
This apparatus may be briefly described as follows:
r
It consists of two rollers as shewn in drawings and marked A and C to which are
attached disc rollers marked B and E E. The apparatus is attached to the machine
by variable brackets or other fastenings according to the make of the machine and
the bottom roller A receives its impetus from the machine by means of bands, tapes or
other gear.
Attached to the top roller O at each end is a disc-roller D D which
11 A

page_text: communicates the impetus from the bottom roller A and the two rollers A and Care
kept running, together at uniform speed in the direction in which the sheet leaves
the machine. On the roller A and, are placed disc rollers B and E E which may be
fixed or alterable as desired by set screws as shown in the drawings. At the outlet.
when the paper or other material leaves the machine after it has passed through the
printing or other process this improved delivering or taking off apparatus is fixed in
such a position that the sheets on leaving the machine are carried between the rollers A
and C by the tapes F F F F as shown in the drawings, the dotted lines indicate the
sheet which in passing through rollers A and C is pressed upward by disc roller B
making a ridge and downwards by disc rollers E and E making furrows and thereby
stiffening the sheet of paper or other material secures the accurate delivery of same.
Where very large sheets are to be delivered extra disc rollers are added as in second
drawing which may be increased as desired making more ridges and furrows.
The disc rollers B and EE are capable of any adjustment desired along rollers A
and C and may be covered with rubber or other material.
In place of the disc rollers, rods, points or tapes may be used to deflect the sheets
into ridges and furrows but the effect is best produced by disc rollers as herein
described.
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 :
1. That it is an automatic, self delivering, simple taking off apparatus, whereby the
paper or other material is deflected into ridges and furrows and gets atmospheric
support producing stiffness and enabling the delivery accurately into the desired.
position without damaging the material.
2. There are few working parts to get out of order.
3. That it does away with manual labour in taking off or delivering the material
from the machine.
