PROVISIONAL SPECIFICATION.
Improvements in Printing Machines.
I, EDWIN BARRON, of 85 Fairfax Road, Hampstead, in the County of London,
Commission Agent, do hereby declare the nature of this invention to be as follows
-
My invention relates to printing machines which are specially applicable for use
by tradesmen for printing upon paper bags and wrapping paper, but which are also
applicable for other purposes.
According to my invention I provide a suitable bed or table upon which the bags,
or the like, to be printed rest.
The type, which is preferably in the form of an india-rubber printing pad, is
mounted upon a cylinder working in suitable guides, secured to the said bed or
table and bears with its entire weight upon the paper, whereby, as the bags or the
like are drawn one at a time beneath the said cylinder, the latter automatically
adjusts itself so as to bear with an uniform pressure upon the paper or the like.
As in all cases the length of the bag or paper to be printed will not correspond
with the length of the circumference of the cylinder, I provide means for raising the
type cylinder from the paper so that the bags or the like may be withdrawn without
rotating the type cylinder which is thus left in position for printing the next bag or
the like. For this purpose I can employ slings surrounding the shafts of the said
cylinder and connected by a cord.
An inking roller, which is advantageously made hollow to contain a supply of
ink, is arranged in connection with the type cylinder and preferably adapted to rise
therewith.
Upon the type cylinder are fixed indiarubber bands or roughened surfaces which
will afford a bite for the papers or the like as they are pulled one at a time beneath
the type cylinder so that the paper shall not ship relatively to the said cylinder
I sometimes provide for printing upon an endless web of paper, in which case an
impression cylinder is placed beneath the type cylinder, the paper being led between
the said cylinders.
Adjacent to the point from which the printed paper emerges from between the
cylinders is a bar or blade for facilitating the severance of pieces of paper from
the web.

COMPLETE SPECIFICATION.
Improvements in Printing Machines.
I, EDWIN BARRON, of 85 Fairfax Road, Hampstead, in the county of London,
Commission Agent, 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:-
My invention relates to printing machines which are specially applicable for use
by tradesmen for printing upon paper bags and wrapping paper but which are also
applicable for other purposes.
According to my invention I provide a suitable bed or table upon which the bags
or the like to be printed rest.
The type, which is preferably in the form of an india-rubber printing pad or sheet
is mounted upon a cylinder working in suitable guides, secured to the said bed or
table and bears with its entire weight upon the paper, whereby, as the bags or the like

page_text: are drawn one at a time beneath the said cylinder, the latter automatically adjusts
itself so as to bear with an uniform pressure upon the paper or the like.
As in all cases the length of the bag or paper to be printed will not correspond with
the length of the circumference of the cylinder, I provide means for raising the
type cylinder from the paper so that the bags or the like may be withdrawn without
rotating the type cylinder which is thus left in position for printing the next bag
or the like For this purpose I can employ slings surrounding the pivots of the
sid cylinder and connected to cords
An inking roller or rollers, advantageously made hollow to contain a supply of
ink, is or are arranged in connection with the type cylinder and preferably adapted
to rise therewith.
Upon the type cylinder are fixed india-rubber bands or roughened surfaces which
will afford a bite for the papers or the like as they are pulled one at a time beneath
the type cylinder so that the paper shall not slip relatively to the said cylinder.
I sometimes provide for printing upon a continuous length of paper, in which
case a roller or reel carrying the said paper is placed beneath the type cylinder.
Adjacent to the point from which the printed paper emerges from beneath the type
cylinder is a bar or blade for facilitating the severance of pieces of paper from the
continuous length.
To enable iny invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawing, in which
Figure 1 is a front elevation, and
Figure 2 is a side elevation of a printing machine constructed according to my
invention and adapted for printing upon paper bags or sheets of paper.
Figure 3 is a similar view to Figure 2 but showing the machine adapted for printing
upon a roll or continuous length of paper
Figure 4 is a front elevation of the bar or blade for severing pieces of paper from
the roll.
Similar letters of reference are used in all the figures to indicate corresponding
parts.
Referring first to Figures 1 and 2 a is the bed or table upon which the pile of bags
or the like b to be printed rests, c is a plate located in a groove in the bed or table a
and carrying a pin d which is passed through the bags or the like to prevent the
remainder fiom shifting while the top one is being pulled out.
adjusted to suit different lengths of bags or paper and fixed by means of a bolt and

fis the sheet of india-rubber with the type thereon mounted upon the cylinder g
the pivots h, h of which work in the guides (as clearly shown in Figure 2) secured
to the bed or table a The dotted lines, indicate the slings surrounding the pivots h
of the type cylinder g and k, k are the cords attached to the said slings and passing
through guides 1, 1, 1 and terminated by a ring m whereby the type cylinder g
can be lifted so as to withdraw a bag or sheet of paper without rotating the type
cylinder.
n is a hollow perforated and covered roller containing a supply of ink which it
imparts to another roller o on which it bears, the roller o resting upon the type cylinder
and serving to ink the surface of the type thereon. The spindles of the rollers m and o
are located and work in the guides i so that the said roller can rise and fall with the
type cylinder g.
P, P are the india rubber bands or roughened surfaces which I provide upon the type
cylinder g in order to prevent the paper from slipping when being drawn out.
To make use of a printing machine of this construction, the rollers n and o and
type cylinder must first be lifted by means of the cords k and slings, and the pile of
bags or paper 6 then placed in proper position upon the hed or table a with the
pin d
piercing their rear end. The type cylinder g is then turned by hand so that it shall
print on the required portion of the bags or paper and the said cylinder is lowered
onto the latter. The front end of the uppermost bag is then laid hold of by a finger and
thumb and drawn out and the type cylinder will meanwhile rotate over and print upon

page_text: the surface of the bag, when the next uppermost bag is drawn out it will be similarly
printed upon and so on.
Should the length of the part of the bag or paper over which the type cylinder
revolves not correspond with the length of the circumference of the said cylinder the
latter must, when it has completed one revolution as the bag or paper is being drawn
out, be raised by means of the slings, and cords k so as to allow the withdrawal of the
bag or paper to be completed with further rotating the type cylinder, which, being
again lowered, will be in proper position to print the next bag or paper.
In Figure 39 is the roller or reel upon which the continuous length of paper 18
wound the said reel revolving in bearings & beneath the ty pe-cylinder g so that as the
paper is drawn out or unwound from the reel it will be printed upon by the
type cylinder g. t, figures 3 and 4, is the bar or blade for facilitating the severance
of pieces of paper of the required lengths from the roll wound upon the reel 9. This
bar or blade t is formed with hooks u, u to allow of it being attached to bosses on
the spindles of the type cylinder the blade t being adjacent to the point from which
the printed paper emerges from beneath the type cylinder g so that a downward pull
upon the paper when the required length has been drawn out will cause the blade t to
sever it.
Instead of placing the reel of paper so that the type-cylinder bears thereon it can be
placed in bearings provided at the rear part of the frame of the machine in which case
an impression cylinder would be placed beneath the type cylinder, the paper being led
between the said cylinders.
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) In a machine for printing upon paper bags webs or the like the combination of
a type cylinder so arranged as to automatically adjust itself upon the paper, inking
rollers also adapted to automatically adjust themselves upon the said printing roller
and means for lifting the printing roller out of contact with the paper, substantially in
the manner herein before described.
(2.) In a machine of the kind herein before described and illustrated in Figure 3 for
printing upon a web of paper, the employment of a self-adjusting bar or blade for
severing pieces from the said web, substantially as hereinbefore described and illustrated
in figures 3 and 4 of the accompanying drawing.
(3.) The manufacture and use of the improved machines for printing upon paper
bags, webs, or the like, hereinbefore described and illustrated in the accompanying
drawing.
