An Improved Stone Breaking or Ore Crushing Machine,
We, JOSEPH THOMAS, of 27, Aysgarth Terrace, Beeston Hill, Leeds, JOHN
FOSTER, of 23, Eighteenth Avenue, Tong Road, Leeds, and THOMAS DAWSON, of
, Burton View, Dewsbury Road, Leeds, Engineers, all in the County of York,
lo hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in machinery or apparatus employed for
stone-breaking and ore-crushing.
The objects of our invention are to provide, first, an arrangement for producing
a perfect forward and backward motion direct from crank without the aid of
springs.
Second, a fixed fulcrum bearing for lever.
Third, an arrangement for reducing strain on shaft in short end of lever.

FIGURE 1 (A) IS THE FRAMEWORK of Machine.
Fulcrum-hearing B is fitted with canted brass bushes B₁ and B³, in which is

page_text: The bolts B5 and 16 pass through frame (A) to recesses B7 and B8, where they
are secured by two square nuts.
This being a fixed bearing, there is no necessity for rollers or sliding bearings
as hitherto.
All other bearings in A are of the ordinary construction.
REGULATING TAPer or WEDGE, WITH REGULATING SCREW AND STAR WHEEL AND
TOGGLE-BEARING BLOCK.
Instead of casting a hole right through regulating taper (K, Fig. 1) as hitherto,
and thereby weakening same, we cast a bolt-hole 3 inches down from small end or
top of taper, into which we insert regulating screw (L, Fig. 1). On this regulating
screw is fitted a star wheel (M, Fig. 1) for regulating the taper (k,), by raising or
lowering as required, while the machine is in motion.
The toggle-bearing block (N, Fig. 1) is of the ordinary construction except for
toggle-bearing (O, Fig. 1), which is constructed as hereafter described (under
centre toggle-block E and E³).
This block may be moved forward or backward by means of regulating-taper K.
The toggle-bearing P in swinging jaw G is of similar construction.
Instead of fixing the lubricators for toggles (W, W², Fig. 1) on centre-toggle
block (Figs. 6 and 7) or jaw stock (G, Fig. 1) as hitherto, we cast or bolt our
lubricators (W³ and W, Fig. 1) on the top of toggle (W and W2, Fig. 1) which
by the oscillation of the toggle, acts as a self-feeder to the toggle-bearing.
FIGURES 2 AND 3 ARE THE CONNECTING ROD.
Instead of making the connecting rod with loose cap and bolts, or with strap,
gib, and cottar, as hitherto, we make our connecting rod with solid ends. The
large end is made sufficiently large to allow web of crank to pass through.
The brass bushes in big end are made in two parts C¹ and C². Ce is made with
the under-side inclined to allow adjusting die U to take up wear of bushes C¹
and C³.
By turning screw C*, which passes through connecting-rod and die C³, and to
both ends of which nuts are attached, the die C is moved forward or backward for
adjustment.
The other (or small) end of rod, C, is of the ordinary construction.
FIGURES 4 AND 5 ARE THE LEVER.
The small end of connecting-rod (C³, Figs. 2 and 3) is coupled to forked-end of
lever by means of shaft D', which is secured in lever by key D².
D³ is the fulcrum of lever, into which fulcrum-shaft (B3, Fig. 1) is secured
by taper-cottar D as shewn in Figs. 4 & 5.
In short end of lever a hole is cast for round bush D, split on one side, and
die D6 which is adjusted by screw D.
On under-side of short-end of lever we cast a dove-tailed recess for knuckle-
bearing D³.
FIGURES 6 AND 7 ARE THE CENTRE-TOGGLE BLOCK.
Into centre-toggle block (Figs. 6 & 7) we cast two dove-tailed recesses E¹ and E²,
one on each side, with bolt-holes as shewn.
In these recesses seatings E³ are cast for adjustment of toggle-bearings (E
and E³, Fig. 1).
Instead of fixing toggle-bearings by running in metal, or planing recesses as
hitherto, we adjust ours by chipping seatings, and then applying the keys (Figs. 10
and 11) which are adjusted and secured by bolts.
In bottom portion of centre-toggle block recesses F1, F2, F3, F4, F are cast.
F1 is to admit short end of lever (Figures 4 and 5), through which and through F
a shaft F6 is passed which is secured by cottar passing through F3 or by key as
shewn in Figs. 6 & 7.
The cottar is secured by lock-nuts.

page_text: The strain-block (Figs. 8 and 9) having been inserted into recess F* may be
readily adjusted to knuckle D8 by means of cottar in recess 15, passing under
strain-block as shewn (Fig. 1). On the top of centre-toggle block we cast two
standards F and F8 for return motion lever (Figs. 12 and 13) which is inserted
between the two standards and secured by pin F, Fig. 7.
FIGURES 14, 15, 16 AND 17 ARE RETURN MOTION RODS.
Instead of rods being made one given length, or with left-hand and right-hand
thread in nut or shackle for lengthening, as hitherto, we make ours in two parts G'
and G2 as shewn in Figs. 16 and 17.
G¹ and G2 are made with ordinary hook at one end, and flat toothed part at the
other.
In G¹ is a slot-hole G3, and in G2 a bolt-hole.
A bolt G is passed through both rods as shewn, and thus secures the rods, and
enables them (with slot-hole) to be adjusted for length as required.
The hook of G is then attached to jaw-stock (G, Fig. 1) by means of staple G³,
and the hook of G2 to return motion lever by means of pin G6, (Figs. 12 & 13).
Figures 14 and 15 are an ordinary rod, with hook at each end, one of which is
attached to return motion lever by pin G7 (as in Figs. 12 & 13), the other end
being attached to regulating-screw (Fig. 20).
FIGURES 18 AND 19 ARE ROCKING SHAFT.
The ends of rocking shaft are admitted into holes in the frame A, Fig. 1.
Through the centre of rocking shaft a hole H is cast to receive regulating-screw
(Fig. 20).
FIGURE 20 REGULATING-SCREW & STAR WHEEL.
At one end of regulating-screw a hole H2 is made to receive hook of return
motion rod (Figs. 14 and 15).
Having passed the other end through hole in rocking shaft (as shewn in Fig. 1)
the star-wheel H³ is screwed on for adjustment of return motion rods.
FIGURES 21 AND 22 ARE FLY-WHEEL, PULLEY, AND FRICTION CLUTCH.
Instead of keying fly-wheel R. and pulley S on crank shaft U as hitherto, we
bolt our pulley to fly-wheel.
On fly-wheel are two bosses R' and R2, the inner-one being cast to the fly-wheel,
and the outer-one either cast or bolted to fly-wheel. Between these bosses there
is a taper recess to admit friction clutch T.
In inner-boss we insert bush so that the wheel and pulley may revolve on shaft U
by belt.
"We hold fly-wheel in position on crank-shaft U by placing a sunk-key R³ in
shaft U close up to boss of fly-wheel.
Upon this key we place friction clutch T, which may be applied to recess between
bosses by means of lever arrangement from feeder of machine. This arrangement
dispenses with loose pulley and extended crank-shaft U, and insures safety of
machine.

page_text: 2. Burton View, Dewsbury Road, Leeds, in the County of York, Engineers,
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 machinery or apparatus employed
for stone breaking and ore crushing.
The objects of the present invention are,
First, to avoid the use of rollers or sliding bearings, by the placing of the
fulcrum bearing for lever underneath the frame,
Second, to provide an arrangement for lubricating toggle-bearings,
Third, to provide a connecting rod with solid ends,
Fourth, to provide means for reducing the strain on shaft in short end of lever,
Fifth, to provide adjustable bearings for connecting rod,
Sixth, to provide an arrangement for producing a perfect forward and backward
motion direct from the crank without the aid of springs,
Seventh, to provide an arrangement for simplifying the fixing and removing
of toggle-bearings,
Eighth, to provide an arrangement of friction clutch to machine.
In the drawings lodged with the Provisional Specification we have shown our
improvements applied to one of our own machines but we would have it under-
stood that the connecting rod with solid ends, may be applied to and combined
with other makes or types of stone-breaking and ore crushing machines.
FIGURE 1 (A) IS THE FRAMEWORK OF MACHINE.
Fulcrum bearing B is fitted with canted brass bushes B1 and B2, in which is
fitted fulcrum shaft B³, which is supported by loose cap B and bolts B5 and B.
The bolts B and B pass through frame A to recesses B7 and B³, where they
are secured by two square nuts.
This being a fixed bearing there is no necessity for rollers or sliding bearings
as hitherto.
All other bearings in A are of the ordinary construction.
REGULATING TAPER OR WEDGE, WITH REGULATING SCREW AND STAR WHEEL AND
TOGGLE-BEARING BLOCK.
Instead of casting a hole right through regulating taper (K Fig. 1) as hitherto,
and thereby weakening same, we cast a bolt-hole 3 inches down from small end or
top of taper, into which we insert regulating screw (L Fig. 1). On this regulating
screw is fitted a star wheel (M, Fig. 1) for regulating the taper, by raising or
lowering as required, while the machine is in motion.
The toggle-bearing block (N, Fig. 1) is of the ordinary construction except for
toggle-bearing (O, Fig. 1) which is constructed as hereafter described (under
centre toggle-block E and E³).
This block may be moved forward or backward by means of regulating-taper K.
The toggle-bearing P in swinging jaw G is of similar construction.
Instead of fixing the lubricators for toggles (W, W², Fig. 1) on centre-toggle-
block (Figs. 6 and 7) or jaw stock (G, Fig. 1) as hitherto, we cast or bolt our
lubricators (W3 and W, Fig. 1) on the top of toggle (W1 and W2, Fig. 1) which
by the oscillation of the toggle acts as a self-feeder to the toggle-bearing.
FIGURES 2 AND 3 ARE THE CONNECTING ROD.
. Instead of making the connecting rod with loose cap and bolts, or with strap,
gib, and cottar, as hitherto, we make our connecting rod with solid ends. The
large end is made sufficiently large to allow web of crank to pass through.
The brass bushes in big end are made in two parts C¹ and C².
the under-side inclined to allow adjusting die C³ to take up wear of bushes C¹
C2 is made with
and Cº.

page_text: An improved Dione oreanong or
By turning screw C, which passes through connecting-rod and die C³, and to
both ends of which nuts are attached, the die C3 is moved forward or backward for
adjustment.
FIGURES 4 AND 5 ARE THE LEVER.
The small end of connecting-rod (C5, Figs. 2 and 3) is coupled to forked-end of
lever by means of shaft D', which is secured in lever by key D³.
D3 is the fulcrum of lever, into which fulcrum-shaft (B3 Fig. 1) is secured
by taper-cottar D as shown in Figures 4 and 5.
In short end of lever a hole is cast for round bush D³, split on one side, and
die D6 which is adjusted by screw D7.
On under-side of short-end of lever we cast a dove-tailed recess for knuckle-
bearing Ds.
FIGURES 6 AND 7 ARE THE CENTRE-TOGGLE BLOCK.
Into centre-toggle block (Figs. 6 & 7). we cast two dove-tailed recesses E¹ and E2,
one on each side, with bolt-holes as shown.
In these recesses seatings E³ are cast for adjustment of toggle-bearings (E4
and E, Fig. 1).
Instead of fixing toggle-bearings by running-in metal, or planing recesses as
hitherto, we adjust ours by chipping seatings, and then applying the keys (Figs. 10
and 11) which are adjusted and secured by bolts.
In bottom portion of centre-toggle block recesses F1, F2, F3, F4, F5 are cast.
F is to admit short end of lever (Figures 4 and 5), through which and through F
a shaft F6 is passed which is secured by cottar passing through F3 or by key as
shown in Figs. 6 & 7.
"
The cottar is secured by lock-nuts.
The strain-block (Figs. 8 and 9) having been inserted into recess F may be
readily adjusted to knuckle D8 by means of cottar in recess F5 passing under
strain-block as shown (Fig. 1). On the top of centre-toggle block we cast two
standards F and F8 for return motion lever (Figs. 12 and 13) which is inserted
between the two standards and secured by pin F, Fig. 7.
FIGURES 14, 15; 16 AND 17 ARE RETURN MOTION RODS.
Instead of rods being made one given length, or with left and right-hand
thread in nut or shackle for lengthening, as hitherto, we make ours in two parts G¹
and G2 as shown in Figures 16 and 17.
G1 and G2 are made with ordinary hook at one end, and flat toothed part at the
other.
In G is a 'slot-hole G³, and in Ga bolt-hole.
A bolt G is passed through both rods, as shown, and thus secures the rods,
enables them (with slot-hole) to be adjusted for length as required.
and
The hook of G¹ is then attached to jaw-stock (G, Fig. 1) by means of staple G
and the hook of G2 to return motion lever by means of pin G (Figs. 12 & 13).
Figures 14 and 15 are an ordinary rod,' with hook at each end, one of which is
attached to return motion lever by nin G7 (as in Figs. 12 & 13), the other end
being attached to regulating-screw (Fig. 20).
FIGURES 18 AND 19 ARE ROCKING SHAFT.
T
The ends of rocking shaft are admitted into holes in the frame A (Fig. 1).
Through the centre of rocking shaft 'a hole H¹ is cast to receive regulating-screw
(Fig. 20).
FIGURE 20 IS REGULATING-SCREW & STAR WHEEL.
At one end of regulating-screw a hole H³ is made to receive hook of return
motion-rod (Figs. 14 and 15).
Having passed the other end through hole in rocking shaft (as shown in Fig. 1)
the star-wheel H³ is screwed on for adjustment of return motion rods..

page_text: FIGURES 21 AND 22 ARE THE FLY-WHEEL, PULLEY, AND FRICTION CLUTCH.
Instead of keying fly-wheel R and pulley S on crank shaft U as hitherto, we
bolt our pulley to fly-wheel.
On fly-wheel are two bosses R1 and R2, the inner-one being cast to the fly-wheel,
and the outer-one either cast of bolted to fly-wheel. Between these bosses there
is a taper recess to admit friction clutch T.
In inner-boss we insert bush so that the wheel and pulley may revolve on shaft U
by belt.
We hold fly-wheel in position on crank-shaft U by placing a sunk-key R³ in
shaft U close up to hoss of fly-wheel.
Upon this key we place friction clutch T, which may be applied to recess between
bosses by means of lever arrangement from feeder of machine. This arrangement
dispenses with loose pulley and extended crank-shaft U and insures safety of
machine.
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. In a stone breaking and ore crushing machine the fixed bearing for fulcrum
of lever Fig. 1 (B) as herein set forth and described.
2. In a stone breaking and ore crushing machine the arrangement, construction,
and application of lubricating toggle bearings O. P. E and E. Figure 1, which

cottar in recess F5 passing under strain block as shown in Fig. 1 and secured by
nuts as shown.
5. In a stone breaking and ore crushing machine, the adjustable bearings C¹
and C (inserted into connecting rod (Figs. 2 & 3)) the wear of which is taken up
by adjusting die C as herein set forth and described.
6. In a stone breaking and ore crushing machine the compound downward
toggle action which gives off the forward movement, and which, by means of the
return motion lever (Figs. 12 & 13) and return motion rods (Figs. 14, 15, 16
and 17) gives off the backward motion as herein set forth and described.
