PROVISIONAL SPECIFICATION.
Improved Attachment to the Ends of Blade Frame of a Stone Sawing
Machine.
CARACTACUS LEWIS, Builder and Contractor, 48, Palmer Street, Blackburn,
Lancashire, do hereby declare the nature of this invention to be as follows:-
An attachment of channel, or other suitably shaped steel or iron girders, arranged
at the ends of an ordinary frame stone sawing machine, so as to form additional
parrallel spaces or slots, either above and below, or above only, or below only, the
usual one space or slot, already used in the ordinary saw frame. These slots are
for the admission of the usual clips or fasteners, which are used for the securing
of the saw blades in position in the saw frame.
In accomplishing, the object of my invention I place additional parrallel slots
above and below, the one slot common to the ordinary saw-frame, or I can place
same above only, or below only, to the said common slot, and also at any distance
apart that may be desired from the said one commonly used slot, or from each
other.
By so doing I am enabled to fix the saw blades by means of the usual clips er
fasteners, into any of the parallel slots that may be desired, and I am thus
enabled to saw stones at different levels at the same time. The saws can be so
arranged that all levels of saws finish the stones, through which they pass, at the
same time--and by these means, the quoin ends of stones, steps or edges of land-
ings, can be sawn at the lower level slots, simultaneously with the plain sawing
of stones placed above them, by the saws placed in any higher level parrallel slots,
and with no diminution of the number of the saw-blades used.
I claim for my invention the arrangement of any number of parallel slots, in
excess of the usual one slot in the ordinary stone saw frame, that is, I claim for
my invention two parallel slots, or any number of parallel slots above two slots.

CARACTACUS LEWIS, Builder and Contractor, 48, Palmer Street, Blackburn,
Lancashire, do hereby declare the nature of this invention and in what manner the
[Price 8d.]

page_text: same is to be performed, to be particularly described and ascertained in and by
the following statement:
An attachment of channel or other suitably shaped steel or iron girders, arranged
at the ends of an ordinary frame stone sawing machine, so as to form additional
parallel spaces or slots, either above and below, or above only, or below only, the
usual one space or slot already used in the ordinary saw-frame.
These slots are for the admission of the usual clips or fasteners, which are used
for the securing of the saw-blades in position in the saw-frame.
In accomplishing the object of my invention place additional parallel slots
above and below the one slot common to the ordinary saw frame, or I can place
same, above only, or below only to the said common slot, and also at distance
apart, that may be desired from the said one commonly used slot, or from each
other.
any
By so doing I am enabled to fix the saw blades by means of the usual clips or
fasteners into any of the parallel slots, that may be desired, and I am thus
enabled to saw stones at different levels at the same time, a method not accom-
plished by other saws.
The saws can be so arranged that all levels of saws finish the stones through
which they pass at the same time, and by these means the quoin ends of stones,
steps, or edges of landings can be sawn by saws fixed at the lower level slots,
simultaneously with the plain sawing of stones placed above them by the saws
fixed in any higher level parallel slots, and with no diminution of the number of
saw-blades used.
To further illustrate my invention, I enclose drawings, Figs. 1, 2, 3 and 4.
Fig. 1 shews plan of the saw-frame, marked M.
Fig. 2 shews the longitudinal section shewing the frame M, and also my
arrangement of girders for forming the slots at the ends of the frame. To enable
me to place my additional slots, I have enlarged the usual saw-frame M, so as
to suit requirements.
Fig. 3 shews an enlarged section of the end of the frame M, shewing the slots
D, P, E, F, with saws in position attached, marked S. These saws being fas-
tened and secured in the slots, D, P, E, F, by means of the clips marked C, these
are ordinary clips or dogs and are tightened up by means of the wedges, W.
Fig. 4 shews the end elevation of the frame M, with the parallel slots D, P, E, F.
I have placed four slots in this drawing, of course, I can place either more slots,
or less slots, as may be required. I have called the one usual slot, used in the
ordinary frame P', and and D, D, E, E, F, F, are my additional slots placed above
and below, for the purposes of this drawing I am therefore enabled by means of
the slots being placed at varying levels to saw stones at different levels simul-
taneously.
In the foregoing description, I have used (to attain my object of sawing simul-
taneously at different levels) the usual slots, as they best suit the present require-
ments for fixing saws, and I have placed same in parallel positions. The arrange-
ment of the saw-blades may however be attained by slots that are not parallel,
but inclined or otherwise, or by means other than slots, without prejudicing my
invention.
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:-
The arrangement of all parallel slots above (in number) the one usual slot
common to the ordinary saw-frame that is, I claim two parallel slots as my in-
vention or any number of parallel slots above two slats and I furthan claim

page_text: additional slots above the one usual slot that may not be parallel to the one usual
slot. I also claim any portion or part of a slot, or other arrangement, above or
below, the one usual slot, whereby saws may be attached, so as to enable simul-
taneous sawing at two or more different levels.
