IMPROVEMENTS IN MACHINERY FOR BREAKING CANNEL, COAL COKE AND OTHER MATERIALS
Year: 1883

page_text: LETTERS PATENT to John Woodward of the firm Adam Woodward and Sons
of Queen's Foundry, Union Street, Ancoats, in the City of Manchester, in the
County of Lancaster, Engineers, for an Invention of "IMPROVEMENTS IN
PROVISIONAL SPECIFICATION left by the said John Woodward at the Office
of the Commissioners of Patents on the 10th December 1883.
JOHN WOODWARD of the firm Adam Woodward and Sons, of Queens Foundry,
Union Street, Ancoats in the City of Manchester, in the County of Lancaster,
Engineers, "IMPROVEMENTS IN MACHINERY FOR BREAKING CANNEL, COAL COKE
AND OTHER MATERIALS,"
My invention consists in a combination and arrangement namely, in a plate or
plates toothed or serrated on the face which is placed in a vertical position,
by preference, and is or may be attached to a framing so as to be adjustable,
to and from a series of rollers placed one over the other to rotate in suitable
bearings, these rollers being toothed or serrated on their peripheries.
The upper roller is at the greatest distance from the face of the toothed plate, the
next roller below the upper one, nearer and the next is the nearest to the face of
the toothed plate, three rollers being used by preference.
The material to be broken is fed between the upper roller and the stationary
toothed plate and the large pieces are reduced and the material after passing the
upper roller and plate descends to the next and so on until delivered finally from
between the last roller and the plate.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Woodward in the Patent Office on the 5th June 1884.
JOHN WOODWARD of the firm Adam Woodward and Sons of Queens Foundry
Union Street Ancoats, in the City of Manchester in the County of Lancaster,
Engineers IMPROVEMENTS IN MACHINERY FOR BREAKING CANNEL, COAL, COKE,
AND OTHER MATERIALS.
My invention consists in a combination and arrangement, namely in a plate
or plates toothed or serrated on the face which is placed in a vertical position by
preference and is or may be attached to a framing so as to be adjustable to and
from a series of rollers placed one over the other, to rotate in suitable bearings,
these rollers being toothed or serrated on their peripheries.
The upper roller is at the greatest distance from the face of the toothed plate,
the next roller below the upper one nearer, and the next is the nearest to the face
of the toothed plate. three rollers being used by preference.
The material to be broken is fed between the upper roller and the stationary
toothed plate and the large pieces are reduced and the material after passing the
upper roller and plate descends to the next and so on, until delivered finally from
between the last roller and the plate.
Fig 1 is a sectional elevation and fig 2 is a front elevation of a machine according
to my invention.
Fig 3 is a front view of toothed and ribbed plates, detached.
a is the base plate of the machine, a' the side frames secured to it in which are
formed suitable bearings for three shafts b, b¹ and 6 one over the other.
The shafts between their journals are made square in section with the corners
taken off, Each shaft has a set of toothed crushing wheels c cach wheel having a
square hole to fit the shaft, and the teeth of each alternate wheel on each shaft,
are arranged to come in a line with, and opposite the spaces between the teeth of
the adjoining wheels
The toothed crushing wheels, are screwed against each other on each shaft by
nuts b* at one end of each shaft which screw against a loose tube on the shaft which
comes against the nearest wheel and forces it against the others, and the last one
on the other side, against a shoulder on the shaft.
d are the fast and loose driving pulleys on the shaft d' which is in suitable
bearings carried on brackets a³ on the base plate.
A pinion d² on this shaft d' gears with a wheel d³ on another shaft d' having
suitable bearings on the stands a³.
A pinion d on the shaft d' drives a wheel 63 fast on the outer end of the top
shaft or roller b another but longer pinion do on the shaft d' drives a wheel 6 on
the outer end of the middle shaft or roller b¹ and a still larger pinion on the
shaft d' drives a wheel b on the outer end of the lower shaft or roller bª.
It will thus be seen that the speed of the highest shaft bis the slowest, the
middle shaft b¹ faster, and the lowest shaft b' the fastest.
The coal or other materials is broken between the teeth of the rollers or shafts
with toothed crushers c and toothed plates e, e¹ and e¹
The plates are secured between the two side frames a¹ and are bolted thereto but
rest against packing blocks a¹ of wood or other suitable material which come
against ledges, formed on the sides of the side frames.
The first plate e is inclined and the middle one e¹ is curved and so is the lower
plate e²
The plates have teeth that pass across horizontally, and they have also ribs e*
serrated on their edges in a vertical position.

page_text: When breaking cannel or any similar substance the material tends to crush into
the form of a slab or cake The vertical ribs ex on the plates e, e¹ and e² cause such
slabs or cakes to be broken in a vertical direction while the curved face of the two
lower plates e¹ and e² causes the slabs or cakes to break in the horizontal direction.
There is a hopper f formed at the top of the framing into which the cannel, coal
or other material is placed or is allowed to fall to feed the machine or the material is
lifted to the machine by any suitable elevator or by scoops carried on suitable
endless jointed chains working on pulleys on two shafts.
The upper shaft, pulleys and gearing, for an endless jointed chain is shown in
figs 1 and.2; g being the upper shaft (the lower one is a similar shaft not shown) in
bearings in side brackets a secured to the side frames a¹, g¹ the pulleys, g³ the
endless jointed chains g³ the scoops, g' a wheel in the shaft g driven by a pinion g
on a shaft ge in suitable bearings on the brackets a³.
There is a pulley g7 on the end of the shaft go driven by a belt from a pulley g³
on the first motion shaft d¹.
I have now particularly described the nature of my said invention and the mode
of carrying the same into effect and claim as my invention.
1. The combination and arrangement of two or more toothed rollers, or shafts
having toothed crushing wheels upon them with fixed serrated or toothed plates
substantially in the manner and for the purpose hereinbefore described and
illustrated by the drawings.
2. The combination of serrated or toothed rollers or shafts, having toothed
crushing wheels upon them, with fixed toothed plates having ribs (ex) substantially
as and for the purpose herein before described.
In Witness whereof I the said John Woodward have hereunto set my hand and
seal this third day of June in the year of our Lord one thousand eight hundred
and eighty four.
