PROVISIONAL SPECIFICATION.
An Improved Appliance for Cleaning Printers' Rollers and the like.
I THOMAS ASHFORD of 24 Philip Road Peckham Rye in the County of
Surrey Printer do hereby declare the nature of this invention to be as follows:-
The object of this invention is to enable printers' rollers to be more readily
cleaned than can be done by the methods hitherto in use.
Now according to this invention I provide a knife or scraper of steel brass, gun-
metal or other suitable material having the edge thereof concave and approximately
semi-circular to fit the roller. One side of the concave portion is bevelled to form
the working edge and I provide a handle at the back of the knife or scraper. I
prefer to form the knives or scrapers of steel in one piece and in sets of six different
sizes which will allow sufficient variation in the diameter of the concave portion of
the knife or scraper to enable one or other of the set to be used to clean rollers of
any ordinary dimensions. Instead of making the knife or scraper in one piece I
may make the same in two or more pieces preferably three the handle and about
one third portion of the edge forming one portion to which I pivot two side pieces
so that by bringing the side pieces nearer together or vice-vers the same knife or
scraper may be made to fit rollers of different diameters.

COMPLETE SPECIFICATION.
An Improved Appliance for Cleaning Printers' Rollers and the like.
I, THOMAS ASHFORD, of 24, Philip Road, Peckham Rye, in the County of
Surrey, Printer, 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 :-
The object of this invention is to enable printers' rollers to be more readily
cleaned than can be done by the methods hitherto in use.
Now, according to this invention, I provide a knife or scraper of steel, brass, gun-
metal, or other suitable material, having the edge thereof concave and approxi-
mately semi-circular, to fit the roller. One side of the concave portion is bevelled.
to form the working edge, and I provide a handle at the back of the knife or
scraper. I prefer to form the knives or scrapers of steel in one piece, and in sets
of eight different sizes, which will allow sufficient variation in the diameter of the
concave portion of the knife or scraper to enable one or other of the set to be used
to clean rollers of any ordinary dimensions. Instead of making the knife or
scraper in one piece, I may make the same in two or more pieces, preferably three,
the handle and about one-third portion of the edge forming one portion, to which I
pivot two side-pieces, so that, by bringing the side-pieces nearer together, or vice-
versá, the same knife or scraper may be made to fit rollers of different diameters.
J herewith append two drawings, viz., Figs. 1 and 2, in order to explain the
matter more fully.
Fig. 1 represents the tool or appliance made in one piece, which I prefer.
A denotes the concave knife or scraper. with bevelled edge.

page_text: B represents a circular orifice for the insertion of the middle finger, by which
means it enables the holder to secure a firm grip of the handle.
C is the handle, shaped so as to fit well into the palm of the hand.
D represents the place where-should I wish to make a tool or appliance of the
kind described the moveable side-pieces would be pivotted on.
Fig. 2 represents the tool or appliance made in three pieces, as above described.
E shows the two moveable pieces, which are pivotted, by means of screws,
on to the third piece, which consists of the handle and centre portion of the edge.
F are the pivotting screws.
G is the handle and centre portion of the edge on to which the two moveable
pieces are screwed.
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. An entirely original tool or appliance for cleaning printers' rollers—either
letterpress or lithographic, and of any diameter.
2. I also claim that the before mentioned tool or appliance will clean either of
the above-mentioned rollers whether on or off the printing machine.
3. I claim also that the tool or appliance saves time and materials, does its work
in a more cleanly manner, and is much cheaper than any other known.
