I WILLIAM HENRY BAXTER, of 12 Albion Street, Leeds, in the County of York,
Engineer, do hereby declare the nature of my said invention for "IMPROVEMENTS
IN STONE BREAKING AND ORE CRUSHING MACHINES AND IN ELEVATING AND
SCREENING APPARATUS CONNECTED THEREWITH" to be as follows:-
This invention consists of improved combination of mechanism for regulating
and controlling the movement of the crushing jaw and to an improved construction
of circular revolving elevator and screening appliance, the latter being devised for
returning to the machine such portions of the stone or ore previously passed
through but not sufficiently reduced without at the same time returning much of
what has been sufficiently reduced or broken small enough by the previous action
of the machine.
.
According to this my invention I employ an eccentric as ordinary upon the
main shaft carrying and operating the movable or swinging jaw, the crushing or
breaking face of which is loose or detachable from the said jaw, the stationary jaw
being fixed to the framing of the machine as ordinary-Behind the movable or
swinging jaw is mounted a roller against which the jaw bears, the said roller is
mounted in a movable slide block behind which block is the ordinary screw
adjustable wedge whereby the position of the slide block and roller in relation to
the back of the swinging jaw is regulated and thereby the amount of movement
cf the said jaw. and the size to which the stone or ores crushed or broken is
determined. The roller referred to may also be raised or lowered whereby and
through the movement of the eccentric the movement of the lower end of the
movable crusher plate is regulated according to the nature of the material to be
operated upon the upper surface of the jaw is not being used at the time the lower
part thereof is in operation, because the upper portion is going forward, whilst
the lower portion is-receding, such motion proceeding through the action of the
eccentric and whereby the strain upon the shaft is greatly reduced.

page_text: The elevating screen consists of a circular cage or drum bolted to a disc or plate
mounted upon a stationary shaft, one end of the drum is divided or partitioned by
an annular ring and by the application of cross division plates forms the elevating
brackets-On the outer face of the drum is a plate bevel wheel in which gears a
pinion mounted upon a standard shaft driven by pulley and strap from the main
or eccentric shaft above referred to-Within the space between the annular ring
and the outer plate at the back of the elevator there is always a lodgment of stone
which assures the natural angle or slope the larger stones passing down the slope
into the brackets which deliver them to the shoot for further operation by the jaws.

page_text: Improvements in Stone Breaking and Ore Crushing Machines,
and in Elevating and Screening Apparatus Connected
therewith.
I WILLIAM HENRY BAXTER of 12 Albion Street, Leeds in the County of
York, Engineer, do hereby declare the nature of my invention for IMPROVE-
MENTS IN STONE BREAKING AND ORE CRUSHING MACHINES AND IN ELEVATING
AND SCREENING APPARATUS CONNECTED THEREWITH and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement:-
This invention consists of improved combination of mechanism for regulating
.and controlling the movement of the crushing jaw and to an improved construction
of circular revolving elevator and screening appliance, the latter being devised for
returning to the machine such portions of the stone or ore previously passed
through but not sufficiently reduced, without at the same time returning much of
what has been sufficiently reduced or broken small enough by the previous action
of the machine.
Such being the nature and object of my said Invention the following is a
complete description of same reference being had to the accompanying drawings
forming a part of this specification in which
n
Fig. 1. is a sectional elevation of machine illustrating the improvements thereon.
Fig. 2. is a plan view of the machine, partly in section on line A. B. of Fig. 1.
According to this my invention I employ an eccentric 1. as ordinary upon the
main shaft 2. carrying and operating the movable or swinging jaw 3. the crushing
or breaking face 4. of which is loose or detachable from the said jaw, the stationary
jaw 5. being fixed to the framing 6. of the machine as ordinary.-Behind the
movable or swinging jaw 3. is mounted a roller 7. against which the jaw bears,
the roller 7. is mounted in. a movable slide box 8. behind which block is the
ordinary screw adjustable wedge 9. whereby the position of the slide block 8. and
roller 7. in relation to the back of the swinging jaw 3 is regulated, and thereby the
amount of the movement of the said jaw, and the size to which the stone or ores
crushed or broken is determined.-The roller 7. may also be raised or lowered
whereby and through the movement of the eccentric 1. the movement of the lower
end of the movable crusher 4. is regulated according to the nature of the material
to be operated upon, the upper surface of the jaw at point 4. is not being used at
the time the lower part thereof at point 3 is in operation, because the upper
portion is receding whilst the lower portion is advancing and vice versae, such
motion proceeding through the action of the eccentric 1 imparting to 4-3 a rocking
motion on 7. and whereby the strain upon the shaft 2 is greatly reduced.-The
elevating screen consists of a circular cage or drum 10 bolted to a disc or plate 11.
mounted upon a stationary shaft 12. one end of the drum 10. is divided or
partioned by an annular ring 13. and by the application of cross division
plates 14. 14. forms the elevating buckets 15°.

page_text: On the outer face of the drum 10. is a plate bevel wheel 15. in which gears a
pinion 17. mounted upon a standard shaft 18. driven by pully and strap 19. from
the main or eccentric shaft 1.
Within the space 10 between the annular ring and the outer plate at the back
of the elevator there is always a lodgment of stone 20. which assumes the natural
angle or slope, the larger stones passing down the slope into the buckets 15" which
deliver them to the shoot 21. for further operation by the jaws 3 and 5.
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 a stone breaking or ore crushing machine the roller so mounted as
described as to cause through and in combination with the action of the eccentric
the upper and lower portions of the movable crusher jaw to alternately come in to
operation as herein described.
2. The improved construction of revolving screen wherein is contained a
separately constructed and acting elevator as, herein described and illustrated by
the drawings annexed.
3. The construction of stone breaking or ore crushing machinery wherein is
contained a movable crushing jaw operated and operating in manner herein
described and a combined revolving screen and revolving elevator as such are
.herein described and substantially as illustrated by the annexed drawings.
