Improvements in the Operating Mechanism of Stone Breaking and Ore
Crushing Machines, applicable also to Punching, Shearing and
other similarly Operated Machines.
I, WILLIAM HENRY BAXTER, of 71, Gelderd Road, Leeds, in the County of
York, Engineer, do hereby declare the nature of this invention to be as
follows:-
-:
This invention relates to improvements in stone breaking and ore crushing
and other machines where similar movements are required, as for instance in
punching and shearing machines. Its object is to provide means consisting of
say, a direct lover action actuated by the pitman or connecting rod,of, say,
a stone breaking machine,-mounted pendantly upon an eccentric or eccentrics
fixed to the driving shaft of the machine and arranged to be carried in bearings
formed in one or more arms or brackets cast or rigidly fixed to, say, the rear of
the movable jaw, or other moving part of a machine, whereby motion or move-
ment is imparted thereto with an increased, say, crushing, or braking, or
other pressure, without any serious loss of movement.
According to this invention and when applied, say, for example, to a stone
breaking or ore crushing machine, the framework of the machine may be of any
suitable shape or contour and it may be made, say, in cast iron or steel, in one
piece, or built up in parts bolted or otherwise fixed together. The fixed jaw is
of ordinary construction and in the usual position, and the movable jaw (also
of ordinary construction) is mounted on and arranged to be pendant from a
shaft carried in suitable bearings (with or without caps or covers) on the frame-
work. The movable jaw may be either fixed on the said shaft, in which case
the latter would oscillate in its bearings, or the shaft may be made a fixture
in its bearings, in which case the movable jaw would require to be made to
Oscillate on the said shaft.
To, say, the rear of the movable jaw is cast or rigidly fixed by any suitable
means one or more arms or brackets provided with suitable bearings with or
without caps or covers. In the said bearings is mounted the driving shaft of
the machine, upon which are mounted one or more fly-wheels, and fast and loose
pulleys, as well as, say, on the portion of the driving shaft that is between
the said bearings is or are mounted one or more eccentrics upon which the
pitman or connecting rod of the machine is pondantly mounted.
The lower end of the pitman or connecting rod is adjustably or otherwise
jointed, say, to a bifurcated end or angle of say, an L or a triangular or other
shaped lever, or between the ends of two such levers, whilst say, ils or their
opposite end or ends or the angle or angles of said lover or levers may be keyed
to a shaft forming the fulcrum carried in fixed or sliding bearings on the frame-
work, and the centre portion or part of each lever or levers which forms, say, a
right angle to each other, may be jointed or otherwise attached either directly
or by means of one or more links to the movable jaw. In the case of a link

page_text: or links being used, it or they may be so arranged as to produce, say, a toggle-
like action upon the movable jaw, the position of the fulcrum of the lever in this
case being moved further away from the point of connection with the link or
links. The distances respectively between the fulcrum of the said lover or levers
and the point of connection between the movable jaw, and between
the point of connection with the movable jaw and the pitman or connect-
ing-rod may be the same or may vary as circumstances require. When the said
lever or levers is or are connected directly to the movable jaw provision is
made, by, say, slightly elongated hole or holes in the said levers or movable jaw
for the movement of the said parts.
When the end of the pitman or connecting rod requires to be made adjustable,
it may be provided with, say, a movable bearing arranged to slide in the end
of said pitman or connecting rod, and to be capable of adjustment by, say, a screw
or screws provided with or without lock nuts. Or the end of the pitman or
connecting rod may be provided with a screwed end arranged to pass through
and beyond a cross bar, the ends of which are made to form trunnions. The
cross bar is connected to the ends of the said levers by its trunnions by any
convenient means. The adjustment of the pitman or connecting rod may be
obtained by one or more nuts arranged to work on the end of said rod and
against one or both faces of the cross bar.
The position of the pitman or connecting rod is made to be adjustable, in
order to regulate the width of opening of the jaw to regulate the size broken
to, in the end or ends of said fever or levers by similar means to that just
described for the end of the pitman or connecting rod.
Other parts of the machine not particularly described may be of the usual and
ordinary construction.
By the means herein described the whole weight of the fly wheels, driving
pulleys, shaft, and pilman or connecting rod is utilized for imparting the crushing
or breaking pressure to the movable jaw.
It will be readily understood that the above described means may be employed
on machines, other than for stone breaking and ore crushing, having a moving
part corresponding or equivalent to that of the said movable jaw, for imparting
motion and power to the same as well as for other purposes.

Improvements in the Operating Mechanism of Stone Breaking and Ore
Crushing Machines, applicable also to Punching, Shearing and
other similarly Operated Machines.
1, WILLIAM HENRY BAXTER, of 71, Gelderd Road, Leeds, in the County of
York, Engineer, 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 stone breaking and ore crushing
and other machines where similar movements are required, as for instance in
punching and shearing machines. Its object is to provide means consisting of
say, a direct lever action actuated by the pitman or connecting rod, of, say,
a stone breaking machine,-mounted pendantly upon an eccentric or eccentrics
fixed to the driving shaft of the machine and arranged to be carried in bearings

page_text: formed in one or more arms or brackets cast or rigidly fixed to, say, the rear of
the movable jaw, or other moving part of a machine, whereby motion or move-
ment is imparted thereto with an increased, say, crushing or breaking, or
other pressure, without any serious loss of movement.
In the drawings hereunto annexed
Fig. 1, is a part sectional elevation of a stone breaking and ore crushing
machine with this invention applied.
Fig. 2, a sectional plan of same on line Fig. 1.
Like parts in all the views are marked with similar letters of reference.
A is the framework of the machine which may be of any suitable shape or
contour, and it may be made, say, in cast iron or steel, in one piece, or built up
in parts bolted or otherwise fixed together.
The fixed jaw B is of ordinary construction and in the usual position, and
the movable jaw C (also of ordinary construction) is mounted on and arranged
to be pendant from a shaft D carried in suitable bearings (with or without
caps or covers) formed for its reception in or on the framework. The movable
jaw C is either fixed on the said shaft, in which case the latter would oscillate
in its bearings, or the shaft may be made a fixture in its bearings, in which case
the movable jaw would require to be made to oscillate on the said shuft.
E are the fly-wheels and F the pulleys, all of which are mounted upon the
driving shaft G.
All the above named parts are of usual and well known construction.
To, say, the rear of the movable jaw C is cast or rigidly fixed by any suitable
means, so as to move therewith, one or more arms or brackets, preferably,
though not necessarily so, two brackets II with a space between, and the said
arms are provided with suitable bearings with or without caps or covers. Caps
or covers are shown in the drawings. In the said bearings is mounted the
driving shaft G of the machine, upon which are mounted one or more fly-
wheels E, and fast and loose pulleys 1, as well as, say, on the portion of the driv-
ing shaft G that is between the said bearings in the arms or brackets H, is or
are mounted one or more eccentrics (one eccentric I is shown in the drawings)
upon which the pitman or connecting rod of the machine is pendantly mounted,
and hangs between the arms H.
SO
Although I have shown the shaft G bolow the level of the shaft D, yet I would
may be
have it distinctly understood that when required, the brackets H
arranged that both of the said shafts will be on the same horizontal level when
the movable jaw C is in the position shown in the drawings.
The lower end of the pitman or connecting rod J is adjustably attached to the
cross bar K through which its end passes and is secured in position by the nut I..
The cross bar K is armed with the trunnions M which project on each side
thereof as shown. On or to each of the trunnions M is placed or otherwise
jointed the bifurcated end of an L or a triangular lever, or between the ends
of two such levers without bifurcated ends such as N. The opposite ends of
the levers N are keyed to a shaft ( forming the fulcrum which shaft is carried
in fixed (or sliding) bearings P' formed in or on the framework A as shown. The
centre portion or part N¹ of each lever N which forms, say, a right angle with
the parts connected to the trunnions M and shaft is jointed or otherwise
attached either directly or by means of one or more links Q to the movable jaw C.
In the drawings one link Q is shown attached at N¹ to the lever N and at R to
the movable jaw C, in each case by pins N' R" arranged to pass respectively
through the levers N and one end or link Q, and lugs C and the opposite
end of link Q. The link Q is arranged so as to produce, say, a toggle-like action
upon the movable jaw C, the position of the fulcrum of the lever in this case
being moved further away from the point of connection by the use of the link.
The distances respectively between ON and N and M that is the fulcrum O of
the said lever N and the point of connection between the movable jaw and
between the said point of connection with the movable jaw and the pitman or

page_text: connecting rod J may be the same or may vary as circumstances require. When
the said levers are connected directly to the movable jaw provision is required
to be made by, say, a slightly elongated hole or holes in the said levers N or
movable jaw Cat R for the movement of the said parts.
When the end of the pitman or connecting rod requires to be made adjustable,
it may be provided with, say, a movable sliding bearing arranged to slide in
the end of said pitman or connecting rod, and to be capable of adjustment by,
say, a screw or screws provided with or without lock nuts. Or the end of the
pitman or connecting rod may be provided with a screwed end arranged to
pass through and beyond a cross bar K armed with ends to form trunnions M
as previously described and as shown in the drawings. The adjustment of the
length of the pitman or connecting rod is obtained by one or more nuts L
being arranged to work on the end of said rod and against one or both faces
of the cross bar K.
The position of the pitman or connecting rod is made to be adjustable, in
order to regulate the width of opening of the jaw C for regulating the size of
the material to be broken. The end or ends of said lever or levers N may
be provided with similar means of adjustment to that just described for the
end of the pitman or connecting rod J, though such means are not shown in
the drawings, and are not absolutely necessary to the working of the machine.
When, however, such means are employed the trunnions M and shaft № may,
if so desired, be provided or armed with dies or runners.
Other parts of the machine not particularly described may be of the usual and
ordinary construction.
By the means herein described the whole weight of the fly wheels, driving
pulys, shaft, and pitman or connecting rod is utilized for imparting the
crushing or breaking pressure to the movable jaw.
It will be readily understood that the above described means may be employed
on machines, ether than for stone breaking and ore crushing, having a moving
part corresponding or equivalent to that of the movable jaw C for imparting
motion and power to the same, as well as for other purposes.
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:
1. In stone breaking and ore crushing and other machines the operating
mechanism constructed and arranged substantially as described and mounted
upon a shaft carried by a moving part of the machine, as and for the purposes
set forth.
2. In a stone breaking and ore crushing machine such as herein described
the combination or the movable jaw armed with bruckets as described and sus-
pended by a shaft or by trunnions mounted in bearings in the framework of the
machine, a shaft mounted in bearings formed in or on said brackets and having
mounted thereon the fly wheels, driving pulleys and one or more eccentrics
on which the upper end of the pitman or connecting rod is mounted and the
lever and link connection constructed substantially as described, and connected
at one end to the pitman or connecting rod and at the other to the movable jaw,
as well as being fulcrummed to the framework of the machine, all arranged and
operating as herein before described.
3. The arrangement and combination of the various parts forming the machine
as a whole, substantially as herein described and as illustrated in the accom-
panying drawings.
