COMPLETE SPECIFICATION..
An Improved Cylindrical Printing Apparatus.
We, RANDAL CRESSWELL of 5 Bedford Place, London, Merchant, and BERNARD
BLOOM of 24 Doughty Street, London, Engineer 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 designed to facilitate the reproduction of documents or notices
by a simple form of printing apparatus requiring little technical skill.
It consists of a central cylinder or roller on which the type can be set up letter by
letter as on an ordinary composing stick, and it is also furnished with an inking roller
or rollers, a roll of paper, and a pressure roller, all working in unison, and has a
cutter for cutting off the paper in suitable lengths.
The printing and inking and pressure rollers are enclosed in a case of suitable size,
which case can also be furnished, with a drawer or drawers to hold the type, which
latter may be of metal, or of metal faced with india-rubber. The cylinder can be
rotated by a crank handle in small sizes of the apparatus, or if preferred in large
sizes by a treadle and crank, or in any other well known way, and the inking
and pressure rollers rotate by contact with it, being pressed against it by suitable
springs.
On the central cylinder are a number of small open grooves or troughs which form
receptacles for the type, at the ends of these grooves is a flange or end piece, passing
through which are screws to tighten the type, and fix it in position. The grooves or
troughs can be cut in the roller or attached thereon as preferred.
I will now refer to the accompanying drawings in which Fig. 1 shews a transverse
sectional elevation, and Fig. 2 a longitudinal sectional elevation of the apparatus.
Fig. 3 shews a plan view of a portion of the central cylinder.
A is the central cylinder. B is the inking roller, of which one or more may be used
if required. is the pressure roller formed of india-rubber or other suitable material.
Dis the paper. E and E' are the springs, which press the rollers B and C against
the cylinder, F is a similar spring forming a break to the paper roll, G is the crank
handle which turns A. H is the cutter to separate the paper. I is the case.
the
J is
paper holder. K is the groove or channel for the type. L is the type. M is the
adjusting screw for L.
The method of working is as follows; The type being placed in the grooves, and
the paper laid between A and C and through H, the handle G is turned and rotates
the cylinder A which at each revolution causes the paper to unwind and pass over the
type, whereby an impression is printed on it at regularly recurring distances, the
attendant tearing or cutting off the paper at each revolution at the fixed knife H; or
a moveable knife can be attached to an eccentric so as to sever the paper automatically
if preferred.
The roller B can be removed for cleaning. It will be covered with gelatine for
metal type, or with cloth if rubber faced type are employed.
The roll of paper D is easily replaced by a new roll when required, the holder J
being removable for that purpose.
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 printing or manifolding apparatus, the revolving cylindrical type-holder A
with the grooves K and screws M, in combination with the inking roller B, the pressure
roller C, the holder J, the roll of paper D, the springs EE and F, the handle G,
the cutter H, and the case I as herein explained and set forth.

page_text: 2. In a printing or manifolding-apparatus with cylindrical type-holder, the method
of printing from metal or rubber faced type, on a continuous roll of paper by means
of the india rubber pressure roller C and of tearing or cutting the paper by the
cutter H as herein explained and set forth.
