I, HERBERT JOHN HADDAN of 67 Strand, in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention, a communication to me
from abroad by Martin Neuerburg of Cologne, Germany Manufacturer, to be as
follows:-
This invention consists in the use of two sectors journalled face to face and forming
crushing surfaces between which the material to be crushed is fed, these sectors being
given a reciprocating rocking movement about their pivots.
For this purpose the two sectors of suitable breadth and radius are mounted on
shafts journalled in a frame of suitable strength and shape. One of the sectors carries
a projecting arm which is connected by a bar to the crank of a driving shaft. On
revolution of the driving shaft the projecting arm is given a reciprocating motion, and
the sector is rocked on its shaft.
The shaft of one or both of the sectors may be made displaceable so that the space
between the two sectors may be varied at pleasure, to determine the width of the
space and to secure the intended distance are arranged two or more set screws by
which the bearings of the sector or sectors may be moved in suitable guides in the
frame. In lieu of thus rigidly securing the shafts these may also be pressed elastically
together by rubber, steel or wood springs, so that in case of necessity the sectors can
separate, to allow any especially hard object which might otherwise injure the sectors,
to fall.
The sectors are so connected with each other by means of coupling wheels or levers,
that they move simultaneously.
Also by the application of corresponding coupling wheels or levers, the rocking
motion of the sectors may be made unequal, so that one sector may move more quickly
than the other. Likewise according to the nature of the material to be crushed, the
surface of the sectors may be smooth or rough or may be provided with teeth ribs or
any other suitable device for increasing the grinding or crushing of the material.
The shafts about which the sectors move may not coincide with the centres of the
sectors and may be arranged eccentrically in such a manner that the distance between
the sectors decreases with their downward movement.

Improvements in Crushing Apparatus.
I, HERBERT JOHN HADDAN, of the firm of Herbert & Co. Patent Agents formerly
of 67 Strand W.C., now of 18 Buckingham Street Charing Cross W.C. in the
County of Middlesex Civil Engineer do hereby declare the nature of this invention, a
communication to me from abroad by Martin Neuerburg of Cologne in the Empire
of Germany Manufacturer, to be particularly described and ascertained in and by the
following statement :—
This invention relates to crushing machines and consists in certain improvements
which are hereinafter described and more particularly pointed out in the claims.
Referring to the accompanying drawings illustrating a crushing machine embodying
the improvements
Fig. 1 is an elevation thereof.
Fig. 3 is a plan, and Fig. 2 a section thereof upon line a b. Fig. 3.
ABCD is a frame of suitable size shape and strength for supporting the hereinafter
described parts forming the crusher and gear or mechanism by which the same is
operated. In said frame are journalled two parallel shafts EF, the one in journal
bearings rigidly secured in the frame, the other in blocks O, held, and capable of being
moved between parallel guiding faces, in such a manner that the shafts E and F may
be approached to or receded from each other. On said shafts are firmly fixed radial
wings or frames X, Y, of sufficient strength having faces cd so contrived that the
blocks G H forming the crushing faces may be secured to such faces, and removed
therefrom for repair or replacement by others. The essential peculiarity of the
faces G H is that their crushing surface or a part thereof should be as the portion of the
surface of a cylinder of which the axis of the respective shaft E F, or a line parallel
thereto, is the axis, said surfaces or parts being opposed to each other in crushing, so
that, during the rocking movement which is given to the shafts E F and frames X, Y,
the upper portions of said parts of the crusher faces approach to and recede from each
other, without the minimum distance between the faces being substantially increased
or diminished. The rear part of the frame X is preferable extended to a suitable
distance and is there connected by a stout connecting rod or pitman L with the crank
wrist on a driving shaft K or with an excentric on said shaft, the latter being driven
by power in any suitable manner. If only one of the crusher faces, that is to say the
face G is operated by power, then the other face H will be similarly and simultaneously
moved by the friction of the material under process of crushing, it is however preferably
to connect the two faces in such a manner that both are operated together independently
of said friction This may be done by connecting the shafts EF so that the one
operates the other, and since the said shafts are displaceable to and from each
other, the following construction may he employed for the purpose since it does
not interfere with the said relative position of the shafts-To the shaft E is secured
the arm or crank lever N and to the shaft F is similarly secured a corresponding arm
or crank lever M equal to N in length, the length being such that the arms extend
each substantially half the distance between the shafts E and F when the latter are in

page_text: their normal or average relative position. One of said arms extends however slightly
above the other arm, and the outer ends of the arms are connected by a link V
in the manner shown in Fig. 1, so as to render the rocking movement of the shaft E
dependent upon that of the shaft F.
The
The blocks O in which the shaft E is journalled are connected by and form a part
of the cross frame or bow W, and to the latter is fixed the spindle e passing loosely
through the plates and 9, the former movable and the latter a part of the
frame ABCD. The plates and g are secured together by bolts hand held apart
by springs P of considerable power so that the plates and 9 may be pressed together
when such great resistance is suddenly opposed to the crushing faces and would
otherwise tend to break the crushers or other parts of the machine.
distance of the frame W, that is to say of the shaft E from the shaft F, is regulated
by the nuts upon the spindle e abutting on the plate . The action of the
crushers is automatic and does not depend upon the weight of the material
introduced between the faces, since the friction against the surfaces of the crushers
carries down the material between the narrowest part of the crusher. To assist in
this movement and to partially crush or compress the material introduced, before
the true crushing in the narrowest portion of the crushing space, the upper part of
each crusher face may be curved outward as at 4 Fig. 3. The faces of the crushers
may be smooth or suitably roughened, grooved, or dressed, or provided with
projecting shoulders, spikes, or the like according to the material which the
machine is intended to crush. Jare side plates enclosing the crushing space. To
provide for the feed of the material between the crushers, the shoot or hopper Q
has been arranged in combination with suitable mechanism for periodically rocking or
agitating the same for the feed of material between the crushers. For this purpose
the shoot Qis in the form of a flat tray open at the forward end, over the space
between the crushers and supported with its rearward end above the level of the
forward end, and conveniently for the insertion of the material to be crushed.
The forward end is slung by rods or equivalents S from brackets as shown in
Fig. 3, and the rearward end is supported by legs R pivoted thereto and to the
frame of the machine. The pin U supported in a suitable manner in or near the
brackets S or elsewhere as shown in Fig. 2 abuts upon the shoot and is adapted
to be struck and propelled against the wall of said shoot by the dog T upon the
frame X, so as to agitate the contents of the shoot and cause material to fall
between the faces at or near the end of each stroke thereof After the with-
drawal of the dog T the spring m causes the return of the pin U to its former
position.
By making the arms N and M of unequal length, the faces move at unequal velocities
thus causing a grinding as well as a crushing of the material.
Amongst the advantages of this machine, it is capable of fulfilling the various
functions which were hitherto performed by the cheek crushers, roller crushers and
pugmill, the crushing of the material is always uniform, and the material does not
clog in the machine-It is also applicable to such materials as coke, coal, pyrites
which require but slight breaking, as well as to such as require to be very finely
ground.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what 1
