I, EDMUND HODGKINSON, 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 adjustable apparatus or appliance for
attaching to clot-roller machines for use in cutting-off or severing predetermined
lengths of clay for tiles as a clay-strip or clay-clot traverses the table of and after
issuing from or leaving the rollers of such machines, and means for ensuring each
roller of such machines rotating at the same speed so that the severed lengths of
clay may be of equal length.
In carrying my said invention into practice, to and against one side of the lower
roller of such machines I fasten or attach a cast-iron or like suitable metallic
disc of suitable size and thickness as a friction-plate by bolts or like means, to
and against the opposite side of such lower roller I connect or fasten a cast-iron
or like suitable metallic disc or plate of suitable size, and thickness by bolts or
like means, such disc having two or more segmental slots of suitable width cast or
formed in or through such plate at a suitable distance from its outer periphery.
A wrought-iron or like suitable metallic lever or levers pivotted about mid-way
of its or their length at a suitable distance above the table of such clot-machines
to metallic uprights or plates attached to the sides of such table or to the framing
of such machines, the said lever or levers having its or their ends furthest from
the rollers pivotted to a steel, wrought-iron or like suitable metallic plate of
suitable width and thickness, the lower edge of such plate being thinned down
so as to form a cutting edge, the inner end of such pivotted metallic lever or levers
being pivotally connected to one end of a wrought-iron or other suitable rod or
levers pivotted about mid-way of its or their length at a suitable distance below
the sides of the said table, the inner end or ends of such rods or levers being
suitably cranked or bent.
It will be readily understood that the rollers of such machines when set in motion
are caused by the metallic friction plate or plates attached to one of their sides to
revolve at an uniform or equal rate, and the strip or length of clay issuing from
between such rollers as it traverses the table of such machines beneath the lower
or cutting-edge of the metallic-blade is severed into definite or predetermined
lengths by such metallic-blade being caused to descend at regular intervals when
the rollers rotate by the head or outer end of metallic bolts which are adjustable
and connect the slotted metallic plate to the opposite side of the lower roller to
that to which the said friction-plate is attached striking against and depressing the
bent or cranked end of the aforesaid lower lever and causing the rods or levers
to vibrate on their pivots and the metallic cutting or severing plate or blade to

page_text: descend at regular intervals, the distance apart of such bolts determining the
length of the clay slabs or tiles being cut, or about to be cut.

Improved Adjustable Apparatus or Appliance for Attachment to Clot-
rolling Machines for use in Severing Definite Lengths of Clay.
I, EDMUND HODGKINSON, 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 adjustable apparatus or appliance for
attachment to clot-roller machines for cutting-off or severing predetermined
lengths of clay for tiles or the like as such clay strips or clots" issue in continuous
lengths, or travel along the upper surface of the table of such machines, and means
for ensuring the rollers of such machines rotating at the same speed so that the
severed clay lengths may be of equal length.
In order that my said invention may be more readily understood and explained
in detail I have hereunto annexed a sheet of drawings on which letters of reference
are marked.
DESCRIPTION OF DRAWINGS.
Figure 1 represents a side elevation of a clot-rolling machine shewing my inven-
tion or appliance attached thereto.
Figure 2 is a plan view of Figure 1.
Figure 3 is a side elevation of the ring I shrink on, or bolt on to one side of
the bottom roller of such machines.
Figure 4 is an enlarged section of the rim shewn at Figure 3, and
Figure 5 is a side elevation or plan view of the shape of bolts I attach, or insert
into such rim.
On referring to the drawings hereto annexed a represents the upper metallic
roller and the lower metallic roller of such clot rollers, to each side
of the roller I attach by bolts and nuts or shrink on a steel or
iron rim c, d of suitable width and thickness, the rim & having a slot
or groove e of suitable size and section formed in same into which a suitable
number of metallic bolts e² are fitted and fixed at a suitable distance apart according
to the length of the "bats" or tiles required, the steel or iron shafts, 3 having
cast metallic toothed wheels a³, 3 of the same diameter, width and number of
teeth keyed or otherwise suitably fastened thereon directly above each other so
as to run in gear.
At a suitable distance from the rollers a and b, at each side of the table f of
such machines I erect wood or metallic uprights g, h having suitable metallic
bearings i, j attached to their upper end for supporting a wrought-iron or steel
shaft k, on which shaft I key or fasten two similar levers 1, m, having suitable
bosses or enlargements formed thereon and a wrought-iron or steel shaft o
fitted or keyed in such bosses, to which shaft I pivottally connect a steel or wrought-
iron blade g in one or more parts with a lower cutting edge.
A wrought-iron or steel shaft r being fitted or keyed to the bosses s at the
rear end of the levers 1, m to the outer end of the said shaft r I attach
one end

page_text: of a steel or wrought-iron rod t, the other end of the said rod t
being screwed into an adjustable coupling u, to the lower end of such
coupling I screw one end of a similar rod to t the lower end of such
rod being connected by a metallic pin to a wrought-iron lever w having
a metallic weight a loosely connected or attached to its fore-end whilst the opposite
end of such lever w fits loosely on a pin y resting in or upon a metallic bearing z,
the outer portion of the rear end of such lever being suitably bent or cranked.
When such clot-rollers a, b and the toothed wheels a³, 63 keyed to the same
shafts are set in motion or revolved in the direction indicated by the arrow A
prepared or pugged clay is forced or driven from the hopper B between the
rollers a,
b by which it is compressed, and as such clay travels forward upon the
top surface of the table f of such machines beneath the blade q, such blade is caused
to descend and divide the continuous strip of compressed clay into definite lengths
according to the distance apart of the bolts e in the rim d, each time one of the
said bolts e depresses the cranked end of the lever and causes the blade to
descend, the weight a causing the said lever w to return to its normal position.
It will be understood that the heads of the bolts e² are placed through the hole
or aperture e of the slot e in the rim & and slid along or in such slot e and secured
therein at a suitable distance apart in such slot according to the length of “bat”
or tile required by means of a metallic nut or nuts e³.

Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
The application to clot-roller machines of a device or apparatus for cutting or
dividing continuous strips of clay into definite lengths as such clay travels along
on the top surface of the table of such machines, such apparatus consisting of a
metallic blade pivotally connected at its upper end above the table of such
machines and actuated by suitable metallic levers, and metallic bolts fixed cir-
cumferentially at a suitable distance apart in a slotted rim formed on or attached
to one end or side of the bottom roller of such machines, so that such bolts project
at right-angles to the side of such roller and may be fixed at various or different
distances apart when required according to the desired length of "bats" or tiles,
the said metallic blade being caused to descend and divide such clay each time
one of the said bolts depresses one end of a pivotted lever while such rollers and
toothed wheels revolve, the said toothed wheels causing such rollers to revolve at
the same or an equal speed, as herein substantially described set forth and illus-
trated on the drawings hereto annexed.
