PROVISIONAL SPECIFICATION.
An Improved Cutter for Glazed Earthenware Pipes, Tiles, and
the like.
We THOMAS WILLIAM MARSTERS 22 Upper Talbot Street Nottingham
Manufacturer and JOSEPH WAGSTAFFE RADFORD 8 Kirkwhite Street
Nottingham Builder do hereby declare the nature of this invention to be as
follows:-
This invention has for its object, to provide, a useful tool for cutting glazed
earthenware pipes and similar glazed ware used in building construction, drainage
and the like.
Our invention consists of two parallel arms preferably of metal tube firmly
connected at one end a suitable distance apart..
The open ends are provided with hardened steel roller cutters fitted on pins in
suitable slots so that they may revolve freely at right angles to the parallel arms
and projecting on the inside of the arms in the direction of each other.
One of the slotted ends carrying the cutters is so formed that it may be adjusted
by means of a screwthreaded pin which may be tapped through the tube forming
the arm, allowing one cutter to be forced in the direction of the other according
to the thickness of the article to be cut.
The adjustable end is Fo constructed that it may be manipulated by a lever and
cam working on the roller cutter and turning it in the direction required, thus
rolling the article to be cut between the edges of the cutters.
The parallel arms are strengthened by two collars or rings connected together
by a pin in the centre and are made so that they may be moved to any distance
along the arms and fixed by means of a thumbscrew.
The pin connecting the collars or rings is also provided with a roller and may be
used as a gauge or measure for cutting any length or distance on the articles
required within the parallel arms. Suitable connections are provided to allow of
the cutter being secured to a bench or table if desired.

COMPLETE SPECIFICATION.
An Improved Cutter for Glazed Earthenware Pipes, Tiles, and
the like.
THOMAS WILLIAM MARSTERS of 22 Upper Talbot Street, Nottingham
Manufacturer, and JOSEPH WAGSTAFFE RADFORD of 8 Kirkwhite Street
Nottingham Builder 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 relates to an improved appliance for cutting glazed earthenware

page_text: pipes, tiles, and similar articles and materials, and has for its object the construction.
of a simple and inexpensive appliance which may be used for articles or materials.
of various thicknesses, and by which the said articles or materials may be cut at.
any given distance from the end or side of the same.
According to this invention the appliance comprises two parallel arms rigidly
connected together at one end, and fitted with a gauge which can be moved on the
said arms, and held at any position thereon. The lower or inner arm at its free
end is provided with a bracket which carries a freely revoluble cutter, while the
upper or outer arm is fitted with a guide which is tapped to form a nut. Sliding
on the above guide is a suitably shaped bracket which carries a circular cutter and
a screw which works within the tapped guide. Means are provided for attaching
the appliance to a fixed bench, and for actuating the cutter carried by the upper
arm, and there may be means for locking the screw and upper cutter in their placed
position?>
This invention is illustrated by the accompanying drawings which are referred
to in the following detailed description.
Fig. 1 is a side elevation, partly in section and Fig. 2 is an end elevation of the
appliance herein referred to.
The parallel arms a and b of the appliance are connected at one end by a
bracket e which has projecting pieces d and e to which the tubular arms a and bare
firmly attached. On the arms a and b is the gauge f which can be fixed at any
position thereon by a screw g, and at the free end of the lower tube b there is a
bracket which is fitted with a hardened steel cutter k which can rotate on its
axle. The upper tube a is fitted at its free end with a guide upon which the box
or bracket m is fitted to slide, and is provided with a serew a working in a tapped
hole in the guide and actuated by a handle o. A screw or other known means may
be provided for locking the screw. The lower end of the bracket m is fitted with
a hardened steel cutter g, which rotates with the spindle and is actuated by a
lever and pawl t through a ratchet wheel s on the spindle.
When the appliance is to be fixed to a bench the bracket c and h are made wide
enough for screw holes as shown.
When a pipe is to be cut with the appliance herein described, the arm & is placed
inside the pipe and the gauge f adjusted according to the length of the piece to be
cut off. The upper cutter q is then lowered until it presses upon the outer surface
of the pipe, the cutter & at the same time being drawn up to the inner surface of
the pipe. The cutter g is then rotated by th lever and is also gradually lowered
until the rotation of the cutters divide the glaze on the inside and outside of the
pipe, the rotation of the upper cutter carrying the appliance round the pipe. For
cutting tiles and other flat articles, the appliance may be fixed upon a bench. The
cutters are actuated as in cutting a pipe, the rotation of the upper cutter pulling
forward the article being cut..
It should be understood that to cut glazed earthenware it is only necessary to
divide the glazed surfaces to enable the article to be broken at the desired fine.
The appliance herein described enables this division of the surface to be made with
accuracy certain:y, and expeditiously.
In modifications of construction the arms a and b are made from a single tube or
metal bar which is bent to the required shape, or the arms a b, and the pieces
and may be cast together in steel, malleable cast iron or other suitable material.
The gauge may be fitted with a roller, it may be in parts so as to be removable
and it may be carried by one arm.
Having now particularly described and ascertain the nature of our said inven-
tion, and in what manner the same is to be performed we declare that what we
claim is :-
1. An appliance for cutting glazed earthenware pipes, tiles and similar articles
and materials, the said appliance comprising circular cutters, means for varying

page_text: the distance between the same, and means for rotating one of the cutters-
substantially as herein described with reference to the accompanying drawings.
2. An appliance constructed substantially as herein described with reference to-
the accompanying drawings, and for the purpose set forth.
