PROVISIONAL SPECIFICATION.
Improvements in Machines for Breaking or Crushing Clinkers from
Refuse Destructors and the like.
We, JOHN HENRY Cox, of 19, Pemberton Drive, in the City of Bradford, City
Surveyor, and JOIN MCTAGGART, of 171, Hammerton Street, Bradford aforesaid,
Refuse Destructor Manager, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in machines for breaking or crushing
clinkers from refuse destructors and the like.
be
To carry out our invention we employ a pair of crushing rollers having teeth
or corrugations round their periphery. These teeth are preferably triangular in
cross section with their apices pointing outwards in a radial direction. The rollers
are mounted in adjustable bearings so that the distance between them may
adjusted to regulate the degree to which the clinkers are crushed and in addition
to this the bearings may be made sufficiently springy to permit any substance
the rollers are incapable of crushing to pass through. The bearings are secured to
a suitable framework and are preferably geared together and are driven by a belt
end spur wheel or in any other convenient manner. A feed hopper is provided
above the crushing rollers and the broken clinkers leaving the rollers may pass
down a chute to an elevator which may feed them to a rotary separator.
The crushing rollers may be made with an outer toothed shell adapted to be
secured upon a cylindrical carrier by wooden wedges passed in from each end.
This facilitates the renewal of the parts exposed to wear and tear at little cost.

Improvements in Machines for Breaking or Crushing Clinkers from
Refuse Destructors and the like.
We, JOHN HENRY Cox, of 19, Pemberton Drive, in the City of Bradford, City
Surveyor, and JOHN MCTAGGART, of 171, Hammerton Street, Bradford aforesaid,
Refuse Destructor Manager, 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 improvements in machines for breaking or crushing
clinkers from refuse destructors and the like.

page_text: To carry out our invention we employ a pair of crushing rollers having teeth
or corrugations round their periphery. These teeth are triangular in
cross section with their apices pointing outwards in a radial direction. The rollers
are mounted in adjustable bearings so that the distance between them may be
adjusted to regulate the degree to which the clinkers are crushed and in addition
to this the bearings may be made sufficiently springy to permit any substance
the rollers are incapable of crushing to pass through. The bearings are secured to
a suitable framework and are preferably geared together and are driven by a belt
and spur wheel or in any other convenient manner. A feed hopper is provided
above the crushing rollers and the broken clinkers leaving the rollers may pass
down a shoot or guide to an elevator which may feed them to a rotary separator.
The crushing rollers may be made with an outer toothed shell adapted to be
secured upon a cylindrical carrier by wooden wedges passed in from each end.
This facilitates the renewal of the parts exposed to wear and tear at little cost.
To fully describe our invention reference is made to the accompanying sheet
of drawings, forming a part of this specification, in which similar letters of refer-
ence indicate corresponding parts in each of the figures.
Figure 1, represents a longitudinal section of our improved crushing machine.
Figure 2, is a plan view of the same with one of the rollers in section.
The frame or bed A is secured upon any suitable foundation and is provided
with bearings B, B in which the driving shaft C is mounted. A spur wheel E on
the end of the driving shaft engages the wheel F on the roller shaft G preferably
mounted in stationary bearings H, H. The roller J is mounted upon the shaft G
and this shaft is geared by the wheels K and L to the shaft G of the roller J2
The roller J is mounted in bearing blocks N, N fitting slots 0, 0 in the frame A.
Springs P, the pressure of which against the blocks N is regulated by the
screws R are placed in the slots ( and springs S, Sare preferably introduced between
such blocks and the other ends of the slots. These latter springs are provided
to keep the rollers out of actual contact. Any suitable form of hopper is provided
to guide the clinkers to be crushed down between the rollers to be broken. The
rollers are made with pointed teeth as shown and the teeth of the wheels K and L
are deeper or longer thani ordinary cog teeth to allow of movement of the rollers
in relation to each other.
The rollers are preferably made with an annular outer shell T secured to the
cylinder U by the wedges V of wood or other like material driven in each end.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. The improved clinker crushing machine, substantially as herein shown and
described and illustrated in the accompanying drawings.
2. A clinker crushing roller formed of a toothed outer shell secured by wedges
of suitable material on to an internal cylinder, substantially as herein shown and
described.
