I CHARLES WARREN of 13 Fore Street Ipswich in the county of Suffolk
Engineer and Machinist do hereby declare the nature of my invention for
"IMPROVEMENTS IN APPARATUS FOR CONVERTING CIRCULAR INTO RECIPROCATING
MOTION to be as follows:-
"
This invention relates to an improved apparatus for converting circular into
reciprocating motion whereby I obtain a multiplying motion without the use of
straps, wheels or cams.
In the accompanying drawing, figure 1 is a plan, figure 2 is a side elevation, and
figure 3 an end view shewing my improved apparatus as adapted for operating &
fret-saw. To the arm a, of the fret-saw having its fulcrum at b, I attach at c¹, a
link c; d, is a corresponding link, having its fulcrum at d¹, the said links form a
joint at e, and are further connected by a rod f, to a crank f'. By this arrangement
it will be seen, that the parts being in the position shown in the drawing, if the
crank f¹, be turned half a revolution, the arm a, will descend to the position shewn
by the dotted lines, and as the crank continues to turn, the arm is again lifted to
its normal position, and so on for each half turn of the crank.
I have described my invention, for the purpose of illustration, as applied to a
fret saw, but it will be obvious, that it is also applicable to other purposes.

I CHARLES WARREN of 13 Fore Street, Ipswich, in the county of Suffolk,
Engineer and Machinist do hereby declare the nature of the said invention for
"IMPROVEMENTS IN APPARATUS FOR CONVERTING CIRCULAR INTO RECIPROCATING
MOTION "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 an improved apparatus for converting circular into
reciprocating motion, whereby I obtain a multiplying motion without the use of
straps, wheels or cams.
In order to enable my invention to be fully understood I will describe the same
by reference to the drawing accompanying my Provisional Specification in which
figure 1 is a plan, figure 2 is a side elevation, and figure 3 an end view shewing my
improved apparatus as adapted for operating a fret-saw. Similar letters in all the
figures represent similar parts.
To the arm a, of the fret-saw having its fulcrum at b, I attach at c¹, a link c;
d, is a corresponding link, having its fulcrum at d¹; the said links form a joint
at e, and are further connected by a rod f, to a crank f¹. By this arrangement it
will be seen, that the parts being in the position shewn in the drawing, if the
crank f, be turned half a revolution, the arm a, will descend to the position shewn
by the dotted lines and as the crank continues to turn, the arm is again lifted to its
normal position, and so on for each half turn of the crank.
I have described my invention, for the purpose of illustration, as applied to a
fret-ṣaw but it will be obvious, that it is also applicable to other purposes.
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 improved apparatus for converting circular into reciprocating motion
substantially as hereinbefore described and represented in the drawing.
