PROVISIONAL SPECIFICATION.
Improved Apparatus for Breaking or Crushing Asphalte Rock and
like Substances.
We, HENRY DANIEL BLAKE, 154 Barry Road, East Dulwich, S.E. Manager
of a Public Company and ANDREW STAPLEY, Sugar House Lane, Stratford, E.
Engineer and Boiler Maker, do hereby declare the nature of this invention to be
as follows:--
Our invention relates to that class of crushing apparatus in which toothed rollers
are employed, as distinguished from what are known as "jaw" machines, (of which
latter the "Blake" machine is a well known type).
The device in accordance with our invention is especially adapted for crushing
asphalte rock, though it may also be advantageously employed for crushing
bitumenous or more or less sticky or viscous substances generally. That is to say:
when the material is in large pieces or lumps, to break up or reduce their size
preparatory to being introduced into any of the well known or usual types of
disintegrating or pulverizing machines.
In carrying out our invention, the lumps of material to be broken, are charged
into a hopper and thence delivered and passed downwards and through a series of
toothed breaking rollers arranged in the same horizontal plane, in pairs, each pair
below and in line with the vertical axis of the top pair. Each of the rollers of
each pair, is of equal diameter, which latter would be suitable to the requirements.
Each pair of rollers is adjustable according to the size of pieces desired to be
produced ready for disintegrating or pulverising; and, the speed of the rollers
being also such as to suit the size of the pieces.
Adjustable scrapers are provided for clearing the teeth of the rollers when
required for the removal of adhering clogging sticky or viscous matters.

COMPLETE SPECIFICATION.
Improved Apparatus for Breaking or Crushing Asphalte Rock and
like Substances.
We, HENRY DANIEL BLAKE, 154 Barry Road, East Dulwich, S.E. Manager
of a Public Company, and ANDREW STAPLEY, Sugar House Lane, Stratford, E.,
Engineer and Boiler Maker, 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 :-
Our invention relates to that class of crushing apparatus in which toothed rollers
are employed, as distinguished from what are termed "jaw" machines (of which
latter the "Blake" machine is a well known type).
Our improved apparatus is especially adapted for crushing asphalte rock, though
it may
be advantageously employed for similarly dealing with or treating bitumenous
or more or less sticky substances generally. It is devised to break up the large
pieces or lumps into comparatively small sized pieces, preparatory to these latter
being introduced into any of the well known types of disintegrating or pulverizing
machines.

page_text: In accordance with our invention, the large lumps of material to be broken up
are charged into a hopper and from thence pass downwards, and through a series
of toothed breaking rollers which are arranged in pairs, of any desired or suitable
number, in the same horizontal plane, the rollers of largest diameter being at the
top. Each pair is disposed below, and in line with the vertical axis of the top pair.
The rollers of each pair are of equal diameter, and they may, by any convenient
means, be rendered adjustable, according to the size of pieces desired to be produced
ready for disintegration or pulverisation. The apparatus being also speeded
accordingly. Suitable scrapers are provided to ensure the removal, from the
teeth of the rollers, of any adhering clogging, sticky or viscous matters.
In order that our invention may the better be understood we have appended the
accompanying two sheets of drawings.
Sheet i, shows a horizontal sectional elevation; and, Sheet 2, a transverse
sectional elevational view of our improved apparatus. Referring to these a is the
hopper for reception of the lumps of material to be broken up, which latter pass
downwards and are dealt with between the top pair of toothed rollers b, b'; thence
to the toothed rollers c, c'; from these to the toothed rollers d, d'; and, thence to a
trough or other receptacle, to be afterwards comminuted in any of the usual
disintegrating or pulverising machines.
A convenient means of effecting the adjustment, before referred to, of the
crushing rollers might consist in the introduction of solid packing pieces in the
bearings, carrying the roller shafts, as indicated in dotted lines at e.
A means for effecting the clearing of the teeth of the rollers of any adhering
clogging matter, might consist of a bar f, extending the length of the rollers,
having adapted thereto a series of scraper arms g, pointed at the end gl where in
contact with the teeth, the bar fis arranged so as to vibrate or rock on the rod h;
the scraper arms being weighted as shown at 1. Guard plates kk are adapted to
the discharge end of the hopper a to provide against the contingency of any pieces
of the material being dealt with falling down outside the ends of the crushing
rollers, and thereby injuring the bearings and impeding the working of and damage
to the machine.
A convenient arrangement of driving mechanism would consist in the employment
of a pulley or rigger l, driven by the engine belt. The pulley shaft would also
have mounted thereon, the spur pinion m (shown in dotted lines Fig. 1) gearing
into the spur wheel n (also shown in dotted lines Fig. 1) carried on the shaft o,
which latter has mounted thereon at each end, the spur pinions p and q respectively;
the spur pinion p gears into the spur wheel r, mounted at one end of the shafts of
the roller b, the shaft s is fitted at the other end with the spur wheel t gearing
into the spur wheel u. The spur pinion 9 aforesaid gears into the spur wheel v
which latter drives the spur pinion w mounted on the shaft of the roller c and
gearing into a corresponding pinion mounted on the end of the shaft of the other
roller c' and also working by means of the spur pinions the lowest pair of
rollers d, d¹.
The frame of our improved machine would preferably be so built up of wrought
iron and steel, that it can be easily taken to pieces, to gain access to any of the
rollers in case of repairs &c.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
In apparatus for breaking or crushing asphalte rock and the like, the employment
of pairs of toothed rollers, each roller of each pair being of the same diameter
arrone of herein described
