Year: 1884

page_text: I WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, and Co, Patent Agents,
Southampton Buildings, London in the County of Middlesex, do hereby declare the
nature of said Invention for "IMPROVEMENTS IN MACHINES FOR BREAKING OR
CRUSHING. STONE ORE, AND SIMILAR MATERIALS."
This Invention relates to machines for breaking or crushing stone, ore, and
similar materials and has for its object to increase the production of this class of
machines as well as to overcome many of the difficulties which exist in the
machines of common construction. The said Invention consists essentially in
arranging a series of two or more jaws on guides so as to slide in a horizontal plane,
the space between the faces of adjacent jaws forming a mouth to receive the
material to be crushed, combined with means for applying power to the series of
jaws to force them to move towards each other, resistance being applied in the
opposite direction, whereby an advance movement imparted to the extreme jaw or
jaws will communicate a corresponding advance movement to the succeeding jaws
through the material which is introduced between them to be crushed, as more fully
hereinafter described.
I will first describe the Invention as having the resistance produced by a fixed
jaw at one end of the series, the power being applied at the other.
Upon the bed of the machine are two parallel rods running longitudinally above
the same from end to end; outside the rear end a nut is applied to each of the
rods and at the other end of the machine the rods run through the fixed jaw with
nuts on their ends. On these rods the several sliding jaws are arranged, so as
to slide freely on the rods as guides. The adjacent faces of the end portions of the
jaws are parallel and they are arranged so as to leave a small space between those
faces, between which springs.are applied, the power of the springs being sufficient
to force the jaws rearward to their normal position.
The central portions of the adjacent faces of the jaws are reduced so as to form
converging crushing faces; these faces are prepared in any of the usual methods of
preparing faces of jaws for crushing material

page_text: To the rearmost jaw the power is applied by an eccentric or the like on the
driving-shaft; this eccentric operates a toggle composed of two toggle-bars; the
forward end of one toggle bar takes its boaring on the back of the jaw; the rear
end of the other bar in liko manner takes its bearing on a stationary seat at the
rear; the adjacent ends of the two bars take their seat on opposite sides of the
toggle block, from which a connecting rod extends to the eccentric, the eccentric
imparting a reciprocating movement to the toggle-block, moving it up and down,
and thereby operating the toggles in the usual manner for such toggles, as in the
well known Blake crusher.
The movement produced by the extension of the toggle is imparted directly to
the jaw, causing it to slide upon the guidos without changing the inclination of its
face with relation to the face of the next jaw, that is to say the inclination of the
faces of the jaws to each other remains the same throughout their movement.
When the machine is in operation the material to be crushed is introduced
between the several jaws. The advanco or forward movement of the jaw under
the action of the toggle brings that jaw to bear upon the material between its
face and the adjacent face of the second jaw; the resistanco of the material being
crushed communicates a movement to the said second jaw against the material
between it and the third jaw, and through that material movement is imparted to
the third jaw upon the material between it and the fixed jaw so that the
crushing force from the first jaw through the other jaws to the fixed jaw. is
communicated through the material between the respective jaws, and that material
being crushed by such movement of the jaws passes downward through the
delivery in the same manner as through the jaws of the Blake crusher. In such
forward sliding movement of the jaws the springs are compressed, then, as the
toggle relaxes the springs react, and force the respective jaws rearward, preparatory
to the forward or crushing movement.
By this construction the adjacent faces of the jaws always maintain the same
inclination with relation to each other, the extent of movement being the same at
the top as at the bottom.
Power is applied to operate the toggles in the usual manner of applying power
to stone-crushers, and the toggle is made adjustable in the usual manner.
Instead of producing the resistance by a fixed jaw as above described, power
may be applied through toggles at both ends of the series and whoreby the power
applied at one end of the series forms a resistance against the movement of the
jaws from the direction of the other end of the series. Thus it will be seen that
the movement of the intermediate jaws is produced through the interposition of the
material being crushed.
While I prefer to arrange the jaws upon the horizontal rods as guides, it will be
evident that they may be otherwise guided, as for instance each end of each jaw
may be constructed with a projecting tongue to work in a corresponding groove in
the frame, a suitablo spring being arranged between the jaws.
While I prefer the toggle mechanism for imparting reciprocating movement to
the series of movable jaws, any suitable mechanism for imparting movement to the
jaws may be substituted therefor.

page_text: I, WILLIAM ROBERT LAKE, of the firm of Haseltino, Lake & Co Patent Agents,
Southampton Buildings in the County of Middlesex do hereby declare the nature
of said Invention for IMPROVEMENTS IN MACHINES FOR BREAKING OR CRUSHING
STONE, ORE, AND SIMILAR MATERIALS" 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 machinery for breaking or crushing stone, ore and
similar materials, and has for its object to increase the capacity of this class of
machines, as well as to overcome many of the difficulties which exist in the
machines of common construction.
The said Invention consists essentially in arranging a series of two or more jaws
on guides so as to slide in a horizontal plane, the space between the faces of
adjacent jaws forming a mouth to receive the material to be crushed, combined
with means for applying power to the series of jaws to force the latter to move
toward each other, resistance being applied in the opposite direction, whereby an
advance movement imparted to the extreme jaw or jaws will communicato a
corresponding advance movement to the succeeding jaws through the material
which is introduced between them to be crushed, and as more fully hereinafter
described.

In the accompanying Drawing :-
Figure 1 is a top view, and
Figure 2 is a sectional side view, shewing the machine provided with one fixed
jaw to produce the resistance.
Figure 3 shews a modification of the guide for the jaws.
Figure 4 is a sectional side view showing the jaws movable, the power being
applied at both ends of the series.
I will first describe the machine as having the resistance produced by a fixed
jaw at one end of the series, the power being applied at the other.
A indicates the bed of the machine and B B two parallel rods running longi-
tudinally above the bed from end to end. Outside the rear end C a nut a is
applied to each of the rods, and at the other end of the machine the rods run
through the fixed jaw D, a like nut b being on these ends of the rods. On these
rods the several sliding jaws E F and G are arranged so as to slide freely on the
rods as guides. The adjacent faces of the end portions of the jaws are parallel,
and they are arranged so as to leave a small space between these faces. Between
these faces springs are applied, here represented as india-rubber collars d, the
power of the springs being sufficient to force the jaws rearward to their norinal
position.
The central portion of the adjacent faces of the jaws is reduced so as to form
converging crushing faces e; these faces are prepared in any of the usual methods
of preparing faces of jaws for crushing material.
To the rearmost jaw G the power is applied, here represented as by an excentric f
on the driving-shaft H; this excentric operates a toggle composed of two toggle-
bars gh, the forward end of the bar g takes its bearing on the back of the jaw G,
the rear end of the bar h in like manner takes its bearing on a stationary sent i
at the rear; the adjacent ends of the two bars take their seat on opposite sides of
the toggle block 1, from which a connecting rod I extends to the excentric, the
Intter imparting a reciprocating movement to the toggle-block Z, moving it up and

page_text: down, and thereby operating the toggles in the usual mannor for such togglos, as
in the well known "Blake" crusher.
The movement produced by the extension of the toggle is imparted directly to
the jaw G, causing it to slide upon the guides without changing the inclination of
its face with relation to the face of the next jaw, that is to say the inclination of
the face of the jaws to each other remains the same throughout their movement.
When the machine is in operation the material to be crushed is introduced
between the several jaws as in the ordinary "Blake" or other crusher. The
advance or forward movement of the jaw G under the action of the toggles,
brings that jaw to bear upon the material between its face and the adjacent face of
the next jaw, the resistance to being crushed communicates a movement to the
said next jaw F against the material between it and the next jaw E, and
through that material movement is imparted to the jaw E upon the material
between it and the fixed jaw D so that the crushing force from the first jaw
through the other jaws to the fixed jaw is communicated through the material
between the respective jaws, and that material being crushed by such movement
of the jaws passes downward through the delivery m in an ordinary manner.
In the forward sliding movement of the jaws the springs & are compressed, then,
as the toggle relaxes, the springs react, and force the respective jaws rearward
preparatory to their forward or crushing movement.
By this construction the adjacent faces of the jaws always maintain the same
inclination with relation to each other, the extent of movement being the same at
the top as at the bottom.
Power is applied to operate the toggles in the usual manner of applying power
to stone-crushers, and tho toggle is made adjustable in the usual mannor, as seen
in Figure 2.
Instead of producing the resistance by a fixed jaw as above described, power
may be applied at both ends of the series as shown in Figure 4. In this Figure I
show three movable jaws, substantially the same as in the preceding Figures, the
power being applied through toggles at both ends whereby the power applied at
one end of the series forms a resistance against the movement of the jaws from
the direction of the other end of the series. Thus it will be seen that the
movement of the intermediate jaws is produced through the interposition of the
material being crushed.
While I prefer to arrange the jaws upon the horizontal rods B as guides, it will
be evident that they may be otherwise guided, as for illustration, each end of each
jaw may be constructed with a projecting tongue n Figure 3, to work in a
corresponding groove in the frame, a suitable spring d being arranged between
the jaws.
While I prefer the toggle mechanism illustrated for imparting reciprocating
movement to the series of movable jaws, any suitable mechanism for imparting
movement to the movable jaw of a stone crusher may be substituted therefor.
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
First. The combination of a series of two or more jaws, arranged upon parallel
guides and made inovable in a path parallel to the said guides, and mechanism
substantially such as described for imparting movement to the said series of jaws,
the said guides serving to support the said jaws in the same inclination with
relation to each other throughout their entire movement, substantially as
described.
Second. The combination of a series of two or more jaws arranged to move
upon guides parallel with the path of movement, the faces of the said jaws being
inclined to each other to produce convergent mouths, the movement of one jaw in
the series being communicated to the next jaw in the series through the material
introduced between them to be crushed, substantially as specified..

page_text: Third. The combination of a series of two or more jaws arranged on guides
and movable thereon, a stationary jaw at one end of the series, and mechanism
substantially such as described for imparting reciprocating movement to the jaw
at the other end of the series, substantially as described.
Fourth. The combination of a series of jaws' arranged upon guides, a fixed jaw
at one end of the said series, a toggle joint at the other arranged to bear upon the
jaw at that end and serving to impart a crushing movement to the said jaws, the
adjacent faces of which converge and form a crushing mouth between each pair
of jaws, and the guides serving to retain the jaws with their faces in the same
inclination to each other throughout their movement, substantially as described.
