PROVISIONAL SPECIFICATION.
Improvements in Mechanism for Sawing or Cutting Stone.
I, JOHN SMITH of Lawkholme Works Keighley in the County of York,
Engineer do hereby declare the nature of this invention to be as follows, that is
to say :-
It relates to improvements in mechanism for sawing or cutting stone of the class
wherein reciprocatory blades are employed and in accordance with my said inven-
tion I arrange and construct certain of the motor parts and framework by and in
which these blades are operated in such a manner that their functions are performed
with greater precision; while further arrange the water pipes used in connection
with these machines so that they may be readily adjusted in any desired position
and so that they will not deteriorate or wear out as rapidly as when other methods
of arrangement are followed.
To attain this object I arrange the sliding blocks from which the reciprocatory
frame carrying the blades is suspended by connecting rods, to be operated by
screws passing vertically through about their centre or middle parts so that the
weight to be sustained by said screws is distributed to act alike or in an equal
degree on all sides of same.
The said screws and sliding blocks are arranged to be between the vertical
supports of the framework, and the frame or longitudinal rails which form the
supports for the blades are mounted in such a manner as to admit the employment
of one or more blades, while the usual feed gear and other operating mechanism is
employed in connection therewith.
The pipes through which the water is fed to the blades while in operation, are
mounted between or otherwise in suitable proximity with the longitudinal rails
carrying said blades such mounting being effected by appropriate bearing pieces
which are formed in such a manner as to enable the adjustment of these feed pipes
in any position laterally, and to enable these pipes to move with and as said blades
are moved the pipes coupled to them are flexible either by being formed of flexible
material or by having a series of joints, while instead of these coupling pipes
extending somewhat horizontally as do the pipes in proximity with the blades they
extend vertically to a feed pipe fixed on the ordinary framework of the machine so
that all the oscillatory movements of these vertical pipes are about their joining
part which is or may be hinged.

COMPLETE SPECIFICATION.
Improvements in Mechanism for Sawing or Cutting Stone.
I, JOHN SMITH of Lawkholme Works, Keighley 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, that is to say :-
It relates to improvements in that class of mechanism for sawing or cutting stone,
wherein reciprocatory blades are employed and in accordance with my said inven-
tion I arrange and construct certain of the motor parts and framework, by and in
which these blades are operated in such a manner that their motions are performed
with greater precision, and I further arrange the water pipe used in connection with
[Price 8d.]

page_text: these machines so that they may be readily adjusted in any desired position and so
that they will not deteriorate or wear out as rapidly as when other methods of
arrangement are followed.
In the accompanying sheets of drawings
Fig. 1 is side elevation of a machine made in accordance with my invention.
Part of the framework being shown as cut away so that parts behind might be
seen.
Fig. 2 is a view of said machine as seen from above.
Fig. 3 is sectional end elevation of said machine.
Fig. 4 is a perspective view showing the machine's feed pipes.
To attain the object of my invention I arrange the sliding blocks a a¹ (from
which the reciprocatory frame b, carrying the blades c, is suspended by the rods d d¹)
to be operated by screws e el passing vertically through about their central or
middle parts, so that the weight to be sustained by said screws e e¹ is distributed to
act alike or in an equal degree on all sides of same.
The said screws ee and blocks a a' are arranged to be between the vertical
supports ff, thus the frame 6 in which the blades o are mounted (by the parts b 68
projecting downward) allows the attachment and use of one, two or more blades c
as may be desired, while the feed gear, consisting of the crank g (which is mounted
upon the shaft operated by the belt k and pulleys and m this latter being fixed
upon the shaft n which derives its motion by the pulley o and belt p from any prime
motor,) the rod r, lever ratchet ratchet wheel u, gearing wheels v v', shafts to w¹
and gearing wheels 2, 3, 4, 5 and 6, is employed for imparting motion to these
screws e el by which they press the blades c into contact with the block of stone.
upon which they have to operate.
By the ratchet wheel u and gearing wheel v being mounted upon the lever y
pivoted at z which may be manually operated by the rod y¹ (which is held in any of
its positions by the screwed handle 7), the wheel v may be thrown out of gear with
the wheel v', thus when the lever 8 is moved by the handle rod 9 so that it may
bring one or other of the wheels 10 or 11 into gear with the said wheel » motion is
imparted through this wheel o at a considerably increased speed to the screw e el
the direction of such motion being in one direction or the other in accordance with
whether the wheel 10 or the wheel 11 is thus in gear by which means the frame b
together with its blades c may be quickly lowered into or raised out of operating
contact with the block of stone a.
The rotary motion of the wheels 10 and 11 is obtained from the shaft n through
the pulleys 12 and 13 and belt 14, the pulley 13 being fixed upon the shaft 15 upon
which is mounted the wheel 16 which gears directly with the wheel 10 and indirectly
with the wheel 11 by means of the wheel 17.
The pipes 18 through which water is fed to the blades c for well known purposes,
are mounted between or otherwise in suitable proximity with the rails forming the
frame b, such mounting of these pipes 18 being effected by their bearing pieces 19
being made to slide loosely upon the cross bars 20 to which they may when desired
be firmly secured by the thumb screws 21 so that their positions laterally may be
regulated as the blades c below them require.
с
To enable these pipes 18 to move with and as said blades c move, notwithstanding
the necessity of coupling them to a stationary feed pipe, as the pipe 22 the pipes 23
which are employed for coupling them to this said pipe 22 are preferably of flexible
material or their coupling joints may be hinged, thus instead of these pipes 23
extending somewhat horizontally as do the pipes 18 they extend vertically to be
joined to the feed pipe 20 by which all the oscillatory movements of these pipes 21
are about their joining parts..
Having now particularly described and ascertained the nature of my. said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is;-
1. The combination of sliding blocks mounted as described, frame for saws,

page_text: hinged to said sliding blocks, rotary screws for operating said sliding blocks and
means for operating said rotary screws substantially as specified.
2. The combination with the reciprocatory frame for the blades of a stone sawing
machine of adjustable pipes arranged substantially as and for the purpose herein
set forth and described.
