I, THOMAS ELLIS MORRIS Rock Cottage 4 East Twthill, Carnarvon in the County
of Carnarvon, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention consists of a Box or receptacle constructed of iron or other suitable
material, bolted to the side of machine, for protecting the gearing from dust or injury,
forming a thrust bearing for the saw spindle, also retaining oil or other lubricating
substance or material wherein the wormwheel and worm revolve.
The gearing consists of an iron saw spindle revolving on two bearings with fast
and loose pullies and flywheel, also fast and loose washers between which the saw is
fixed by a Screw and nut, a worm is fixed on saw spindle revolving between two
bearings one on each side of the box or receptacle forming a thrust bearing for the
saw spindle, the worm works in a wormwheel fixed on one end and a worm on the
other end of a longitudinal spindle both revolving in oil or other lubricating substance
or material within the box or receptical, the longitudinal spindle is carried by a double
bracket placed and fixed inside the box or receptical, the worm works in a worm wheel
fixed on end of a transverse spindle, on which a spur pinnion with clutch jaws and
running loose on the spindle and connected by a sliding coupling box furnished with
a lever whereby the machine is put in motion simply reverseing back the table by hand.
the spur pinnion works in a rack placed or fixed underneath the table on which is
placed the block or Slab of Slate intended to be sawn or cut.
The table is carried on rollers half of which has a flange acting on a guide rib cast
underneath the table forming a guide to the table carring the block or slab of slate
through the saw.
The Bearings for the Spindles of the rollers are made in a rectangular form or shape
and are fitted into tovetail recesses on the face or sides of the bearers or sides of the
machine whereby they can be adjusted to bring the rollers to a true level.
The stand bracket is made so that the pedestal or plummer block which carries the
end of the Saw Spindle is bolted vertically whereby it is made adapted for two
machines.

L, THOMAS ELLIS MORRIS, Rock Cottage 4, East Twthill, Carnarvon, in the county
of Carnarvon, 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 :-
My invention consists of a Box or receptacle constructed of iron or other suitable
material, bolted to the side of machine, for protecting the gearing from dust or injury,
forming a thrust bearing for the saw spindle, also retaining oil or other lubricating
substance or material, wherein the worm wheel and worm revolve.
The gearing consists of an iron or steel saw spindle revolving on two bearings,
with fast and loose pullies and flywheel, also fast and loose washers, between which
the saw is securely fixed by a screw and nut, A worm is fixed by a screw pin on the
saw spindle, and revolving between two bearings one on each side of the box or receptacle,
forming a thrust bearing for the saw spindle, the worm works in a worm wheel, which
is fixed on one end, and a worm on the other end of a longtitudinal spindle both
revolving in oil or other lubricating substance or material within the box or receptacle.
The longtitudinal spindle is carried by a double bearing bracket, placed and fixed inside
the box or receptacle. The worm works in a wormwheel which is fixed on end of a
transverse spindle on which a spur pinnion with clutch jaws and running loose on the
spindle and connected by a sliding coupling box furnished with a lever whereby the
machine is put in motion or simply reversing the table back by hand.
The spur pinnion works in a spur rack placed and fixed underneath the table on
which is placed the block or slab of slate intended to be sawn or ent.
The table is carried on rollers which are fixed on each end of iron spindles having
a bearing at each end, one half of the rollers have a flange acting between two
ribs placed underneath the table forming a guide for the table carrying the block of
Slate.
The bearings for the spindles of the rollers are made in a rectangular shape or form,
and are fitted into dovetailed recesses which are casted on the face of the sides or
bearers of the machine whereby they can be adjusted to bring the table to a true
level.
The stand bracket is made with a centre web or flange, on each side of which is
bolted vertically or horizontally, a pedestal for carrying the end of the saw spindles
of the two machines, which are placed in a line with each other so that the
gearing of both machines would be on the off side from the men who attends the
machines.
I will now proceed to describe in reference to the accompanying drawings, the
manner in which my invention is to be performed.
Figure 1. represents a plan of the Saw spindle S. revolving in two bearings P. P.
one is fixed on the stand bracket T. on which also is fixed another pedestal to suit
another machine, and the other is fixed on the middle side or hearer C. of the machine.

page_text: The worm F. is fixed on the spindle by a screw-stud or key and revolves between two
bearings D. D. which are made one on each side of the box or receptable Z. thus
forming a thrust bearing for the sawspindle, and works in the wormwheel G. revolving
in oil or other lubricating substance, and is fixed on the end of the longitudinal
spindle K. which is carried by the double bracket J. on the other end of the spindle
is fixed the worm O. which revolvs in oil or other lubricating substance retained by
cross bars R. R. The worm F. works in the wormwheel G. which is fixed on the end
of the transverse spindle M. revolving on two bearings D. D. one on the side of the
box or receptacle Z. and the other fixed on face of middle side or bearer C. of the
machine, on which is fitted with a feather key the sliding coupling box N. and works
in the spur pinnion O. which gives motion to the machine by incans of spur rack
placed underneath the table. The two rollers Q. fixed on spindles forming a guide for
the table carrying the block of slate and revolving on two bearings a. a. which are
made in a rectangular shape or form and fitted into recesses b. b. b. cast on face of sides
or bearer ( made with dovetail, rabbate, circular, or square side.
Figure 2. represents end elevation of the stand bracket shewing the mode the two
pedestals P. P. are fixed or bolted to the web or flange W.
Figure 3. represents front elevation of the rectangular bearings a. a. a. for the roller
spindles.
Figure 4. and 5. represents enlarged plan of the receesses and bearings in their
different shape or form a. a. a. and b. b. b. for the roller spindles.
Figure 6. represents end elevation of the box or receptacle Z. shewing the position
of the worm F. revolving between the two bearings D. D. and working in the worm-
wheel G. also part of the cross stretcher H. which carries the sides or bearers C. of
the machine.
Figure 7. represents front elevation of the box or receptacle Z. shewing the position
and connection of the worms F. F. and the wormwheels G. G. also the position of the
longtitudinal spindle K. and also the double bracket J.
The same letters refer to the same parts in all the different figures.
Having now described the nature of my invention, and the manner in which the
same is to be performed, I wish it to be clearly understood that what I claim as my
invention is a new and improved gearing for slate slab sawing machines, according to
the accompanying drawings.
First. The construction and arrangement of a box or receptacle for protecting the
gearing from dust or injury, forming a thrust bearing to the saw-spindle, also retaining
oil or other lubricating substance or material whereby the gearing are lubricated
reducing the friction to a mimim.
Secondly. The arrangment of the gearing constituted of right and left hand worms
and wormwheels, which can be adapted for right or left hand machines as may be
required.
Thirdly. The construction and arrangement of the bearings and recesses for the
bearings of the spindles of the rollers, by lowering or raiseing then they can be
adjusted to bring the rollers to a true level.
Fourthly. The construction and arrangement of the stand bracket whereby it is
made so adapted that one or two pedestals can be fixed or bolted to suit one or two
machines when it is so required.
