PROVISIONAL SPECIFICATION.
Improved Saw Blade for Sawing and Dressing Stone, Marble, and
the like.
I, JAMES HENRY HOWARTH, of 1 St. Saviour Street, Chorlton-on-Medlock,
Manchester, in the County of Lancaster, Stone Sawyer, do hereby declare the
nature of this invention to be as follows:-
This invention relates to the formation or construction of saws such as are em-
ployed for cutting and dressing stone, marble, and the like; The object of this
my invention is to obtain a self regulating saw blade so as to enable shot or sand
that is employed in the operation of cutting and dressing said stone, marble or the
like to be distributed in a manner that is more effective than when employed with
saws as previously formed or constructed.
In the accompanying drawing I have shown a face view of a short length of
a self regulating saw blade that is constructed according to this invention the dotted
lines representing the face of the reverse side of the same blade. In this invention
I construct a saw blade a by either rolling, stamping or pressing a bar of steel
or iron so as to produce therein diagonal and vertical grooves b and c, and diamond
or like shaped raised portions as d and e: Said grooves and raised portions are
arranged so that on the reverse side the raised portions will form the backs of the
grooves which are on the opposite side, in order that the strength of the saw blade
may not be impaired by the aforesaid grooves. I form the grooves b and the raised
portions d and e so that all the points f shall be in the same plane; by these means
the diagonal grooves b are zizaged and the shot or sand which is fed into the upper
vertical grooves is diverted into different channels before reaching the lower
vertical grooves. By these means improved results in working are obtained.
Dated this 21st day of December 1896.

page_text: 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 the formation or construction of saws such as are em-
ployed for cutting and dressing stone, marble, and the like; The object of this
my invention is to obtain a self regulating saw blade so as to enable shot or sand
such as is employed in the operation of cutting and dressing said stone, marble, or the
like to be distributed in a manner that is more effective than when employed with
saws as previously formed or constructed.
I effect this object by the means hereinafter described, reference being made to
the accompanying sheet of drawings in which
Fig. 1 represents one side, and Fig. 2 the reverse side of a short length of a
self regulating and self polishing saw blade that is constructed according to this
my invention.
Fig. 3 is an edge view of the same.
In the several views shown, similar letters refer to similar parts.
I construct a self polishing and self regulating saw blade as a by either rolling,
stamping or pressing a bar of steel or iron so as to produce therein diagonal and
vertical grooves b and c and diamond or like shaped raised portions as d and e; said
grooves and raised portions are arranged so that on the reverse side the raised
portions will form the backs of the grooves which are on the opposite side, in order
that the strength of the saw blade may not be impaired by the aforesaid grooves;
I form the grooves b and the raised portions d'and e so that all the points f
shall be in the same plane; By these means the diagonal grooves 6 are zigzaged
causing the shot or sand which is fed into the upper vertical grooves to be diverted
into different channels before reaching the lower vertical grooves, thereby obtaining
improved results in working, and the saw blade is not weakened as when otherwise
grooved or corrugated.
Having now particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed, I declare that what I
claim is:
Saw blades such as are employed for sawing and dressing stone, marble and the
like, constructed with diagonal and vertical grooves, and diamond or like shaped
projections on each of the faces of said saw blades, said diagonal and vertical
grooves and raised portions being arranged so that on the reverse side or face of
the saw blade the raised portions will form the backs of the grooves which are on
the opposite face or side, in the manner and for the purpose substantially as
herein before described.
