COMPLETE SPECIFICATION.
A Cutting Tool for Lead Pipe and like purposes.
1, CHARLES FOWLER of Northallerton, Yorkshire, Plumber, 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 :-
This invention is designed to supply a handy and effective kind of shears for
severing lead pipes without compressing them unduly, and consists of two lever
arms connected by a loose rivet or bolt at their outer ends forming a hinge or
pivot joint which serves as a fulcrum to the lever arms one of which carries the
blade and the other bears a curved slotted lip or rest of suitable shape for
sustaining the pipe. It will be observed that the blade has great strength and is
ground rather suddenly to the cutting edge, also that the lower arm has a slot for
the passage of the blade. The two parts are the blade and the slotted holder on
which the tube is placed.
I will now describe the invention with reference to the accompanying drawings
in which
Fig. 1 shows a plan view of my lead pipe cutter with two different forms of
handle, and the cutting blade one solid piece of steel.
Fig. 2 shows a similar view to Fig. 1 without the handles with pipe in position
for cutting. The blade in this case is fitted with a strengthening back of
U section.
Fig. 3 shews a cross section of the cutting blade on line 1-2 of Fig. 2.
Fig. 4 shews a plan view of the slotted arm.
Fig. 5 shews a similar view but with the slot widened at the outer end to receive
the knuckle of the cutting bar.
Fig. 6 shews a plan view of the cutter blade.
Fig. 7 shews a back view of the cutting arm.
a, is the cutting blade, with the cutting edge a', and with or without strengthening
back a², (Fig. 2).
, is the slot in the curved arm.
c, is the pivot pin or bolt on which the two arms work.
d, is the semi-circular lip or bearing formed on each of the outer sides of the
curved slotted arm to receive the pipe.
is the wooden handle.
e, is an iron handle solid with the arm.
1, is a tang for (Figs. 4 & 5) receiving the wooden handle.
It may be formed on the end of the arm in the usual way.
Instead of this form
the tang may be carried through the handle and rivetted as shewn in dotted lines
(Fig. 1).
a, is the usual shoulder.
In use it is only necessary to lay the pipe on the lip or bearing and press the
handles together, when the pipe will be readily severed, and with very little
disturbance of shape.
It will be observed that the blade has great strength and is ground rather
suddenly to the cutting edge, also that the lower arm has a slot b for the passage of
the blade.
The tool can be made of any suitable metal, the blade being by preference of
tempered cast steel.

page_text: This steel may form the whole of the cutting side or half of the tool, or may be
joined thereto.
The tool will be made of various sizes.
A stop or cushion may be attached to act as a buffer when the pipe is severed.
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 :-
In a shears or cutting tool for pipes of soft metal and for like purposes, the lever
arms a a³ fulcrummed at c one of which carries the blade a and the other the lip or
rest d and slot bas herein described and set forth.
Dated this 5th day of December 1894.
