PROVISIONAL SPECIFICATION.
Improved Method of and Apparatus or Machines for Making Ridge-
Tiles, and in Attachments to Clot-rolls to Adapt same for Use in
Making such Tiles.
I, EDMUND HODGKINSON, Clifton House, Heathcote Street, Chesterton, Stoke-
on-Trent, Staffordshire, Brick and Tile Manufacturer and Colliery Proprietor,
do hereby declare the nature of this invention to be as follows:
This my invention has reference to an improved method and apparatus or
machines for making clay or earthenware ridge-tiles, and in metallic segments
for attaching to the rollers of clot-machines for the same purpose, the objects of
my said invention being to make such ridge tiles by rollers in the same way
that flat or roof tiles are made, to ensure the two sides of such tiles being at a
correct angle one with the other, and to save labour, material and time.
In carrying this invention into practice I make the cast-iron or steel bottom
roller of such machines with a continuous vee-shaped groove of suitable and
uniform depth and width in its periphery having flat sides at any suitable angle
with each other, the upper or top metallic roller of such machines I make with
a continuous and tapering uniform projecting periphery having flat sides at the
same or corresponding angle to each other as the inclined flat sides of the vee-
shaped groove in the bottom-roller.
When adapting clot-rolling machines such as are used for making flat or roof-
ing-tiles from plastic-clay or earthenware for use in making ridge-tiles I bolt
or otherwise suitably fix any convenient number of cast-iron, steel or other suit-
able metallic segments to the bottom roller of such machines so as to form a con-
tinuous circumferential vee-shaped groove with flat sides at any suitable angle
with each other, and of uniform depth and width in or around such roller, to the
periphery of the top or upper roller I bolt or otherwise suitably fix any con-
venient number of cast-iron, steel or other suitable metallic segments so as to
form a continuous tapering projecting circumference thereon of uniform depth
and width with flat sides at a similar angle to each other as the sides of the
vee-shaped groove in or on the bottom roller.
It will be readily understood that machines having rollers fitted thereto of the
shape described, or the rollers of clot-machines having metallic segments of the
shape described fixed or bolted thereto will when set in motion press the prepared,
or mixed and pugged clay as it is pushed or forced between such rollers by a
mixing machine into a vee-shaped section of the required angle in a continuous
length on to a vee-shaped trough where by means of a suitable cutter operated
mechanically or by hand such issuing length of pressed or rolled clay is divided
into the required lengths.
When flanges are required on such divided lengths of vee-shaped clay a strip
or lengths of plastic clay is or are pressed on to such pressed or rolled tiles in
the required position whilst in a clay-state before firing such tiles.

Improved Method of and Apparatus or Machines for Making Ridge-
Tiles, and in Attachments to Clot-rolls to Adapt same for Use in
Making such Tiles.
I, EDMUND HODGKINSON, Clifton House, Heathcote Street, Chesterton, Stoke-
on-Trent, Staffordshire, Brick and Tile Manufacturer and Colliery Proprietor,
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 my invention has reference to an improved method of and
apparatus or machines for making clay or earthenware ridge-tiles such
as rolled ridge, capped ridge, plain-ridge, fast or ornamental ridge,
hip-tiles, valley-tiles, wall ridge or coping, rolled garden ridge and the
like ridge tiles, and in metallic segments for attaching to the peripheries of
rollers of clot machines for the same purpose, the objects of my said invention
being to make such ridge-tiles by using rolls or rollers to ensure the two sides
of such tiles being at a correct angle one with the other, and to save labour,
material and time."
In order that my said invention may be readily understood I have hereunto
annexed a sheet of drawings on which letters of reference are marked.
DESCRIPTION OF DRAWINGS.
Figure represents a side elevation of a clot-rolling machine similar to that
described in the Specification of my Patent 28168 dated the 30th day of November
1897.
Figure 2 is a plan view of Figure 1.
Figure 3 is an end elevation or edge view of the lower portion of the top or
upper cast-steel or like suitable metallic roller a and an end elevation of the lower
cast steel or metallic roller b which I fit to or use in such machines for rolling
or making continuous strips or lengths of compressed clay of the required trans-
verse section for valley-tiles, the lower roller having a continuous vee-shaped
groove of suitable size turned or formed in its periphery with flat inclined
sides d, e at any suitable or required angle with each other and a flange bª of
suitable size formed on or fixed to each of its sides, the upper roller having a
turned or machined projecting continuous periphery f with inclined flat sides g. h
formed thereon at the same angle or at about the same angle with each other, as
the inclined flat sides of the vee-shaped groove in the lower roller.
Figure 4 is a side elevation of the roller b and a portion of one of its side
flanges b².
Figure 5 is an end elevation or edge-view of the bottom metallic roller and a
portion of the top metallic roller of clot-rolling machines such as those shewn
at Figures 1 and 2 having a flat or plain periphery which may be adapted for use
in making hip-tiles, valley-tiles and similar ridge-tiles, or continuous lengths
of compressed clay of the required transverse section for such tiles by bolting
or securing cast-steel or like suitable metallic segments of suitable transverse
section to the flat or plain peripheries of such upper and lower rollers so as
to form a continuous vee-shaped groove with flat sides at any suitable or required
angle with each other on the periphery of such lower roller, and a continuous
projecting periphery with inclined flat sides at any suitable or required angle
to each other on the upper roller similar to those shewn at Figures 3 and 4.
Figure 6 is an end elevation or edge-view of a portion of a metallic top-roller
having a periphery with a continuous bead or projection 2 of suitable transverse
section turned or formed on same, and a lower cast-steel or metallic roller with

page_text: a continuous vee-shaped groove c formed therein, or metallic segments, may
be bolted on or to the peripheries of flat or clot rolls for forming such continu-
ous beads or projections and vee-shaped grooves for the purpose of rolling or
making continuous lengths of compressed clay for coping-tiles or ridge tiles of
the transverse section 1.
Figure 7 is a side elevation of one of the metallic segments shewn at Figure G
attached or fixed to or around the periphery of the upper roller a.
Figure 8 is an end elevation or edge view of a top metallic roller u with a
projecting periphery having inclined sides y, h formed or turned thereon, or
metallic segments may be bolted or secured to the periphery of a plain roller
BO as to form a continuous angular periphery as before described, and
Figure 8 a transverse section of the lower portion of a lower metallic roller b
having a continuous vee-shaped groove c with inclined flat sides d, e and a con-
tinuous groove of a circular or somewhat circular transverse section k formed in
or turned in its periphery in the position shewn, or metallic segments may be
bolted on or to the peripheries of plain or clot-rollers to form such continuous
grooves around such rolls for use in making roll-ridge-tiles.
For rolling or making hip-tiles, channel-bricks and wall coping or wall ridges
from plastic-clay or the like material I form a continuous rounding or semi-cir
cular or somewhat semi-circular or convex periphery on the upper metallic roller,
and a continuous groove of similar shape or section on the lower metallic roller,
or metallic segments of the required shape may be bolted on or fixed to the flat
or plain peripheries of clot-rolls or rollers for forming such continuous round-
ing periphery and continuous groove in or on such rolls.
It will be readily understood that as pugged-clay or prepared clay is
forced or driven from a hopper between the upper and lower rollers
used or rotated, such clay as such rollers rotate 1S
such rollers into
compressed by
the required transverse section and propelled for-
ward by such rollers in a continuous length or strip in or on the vee-shaped or
other suitably shaped trough or table attached to such machines beneath an
adjustable steel or like suitable metallic blade having a horizontal, an inclined
or curved cutting edge or edges which blade is caused to descend at regulated
times or intervals to cut or divide such' continuous length of compressed clay
into definite lengths in the manner described in the Specification of my Patent
28168 of 1897 hereinbefore referred to.
Rolled and capped ridge-tiles, or ornamental ridged tiles may be rolled in
the manner described and afterwards finished whilst in a plastic or green state
in the usual well known way and afterwards fired.
Having now particularly described and ascertained the nature of my said
invention and in what maner the same is to be performed, I declare that what
I claim is:-
-
1. The method of making a continuous length of compressed pugged or pre-
pared plastic clay of required shape in transverse section by means of suitable
metallic rolls or rollers fitted to a clot machine or like machine, and dividing
such compressed length of clay into definite or determined lengths by means of
an adjustable cutter or apparatus attached or fixed to or adjacent to the table
of such clot-rolls or machines as illustrated on the drawings annexed, and illus-
trated, described and claimed in the Specification of my Patent 28168 of 1897
for making hip-tiles, valley-tiles, coping-tiles, ridge-tiles, channel bricks, wall
coping or ridges, capped-ridge tiles, roll ridge tiles, fast or ornamental ridge
tiles, garden ridge or edge tiles and similar tiles as herein substantially described
and set forth.
2. The application of metallic segments of suitable transverse section to the flat
or plain periphery of clot rolls, or the rolls of like machines for adapting such
rollers for use in making a continuous length of compressed pugged or prepared
clay of the required shape in transverse section and dividing such length of

page_text: compressed clay into definite or determined lengths by means of an adjustable
cutter or apparatus illustrated on the drawings hereto annexed, and described,
illustrated and claimed in the Specification of my Patent 28168 of 1897 for making
hip-tiles, valley-tiles and other tiles, copings and ridges as herein substantially
described and set forth.
