page_text: I JOHN CHARLES BAUER, of No. 11 Comerford Road, Brockley, in the county
of Kent, Engineer do hereby declare the nature of this invention to be as
follows:-
This invention relates to the construction of a novel and simple apparatus for
cutting metal pipes or tubes.
In carrying out my invention I employ a cutter or cutters provided with saw
teeth and arranged so as to be operated by a lever, so that when the cutter or
cutters is or are moved around the pipe with which the said teeth are brought in
contact by means of a spring or by the action of the lever, the pipe will be cut.-
The edge of the cutter or cutters operates or operate obliquely against the pipe.

page_text: I, JOHN CHARLES BAUER, of No. 11, Comerford Road, Brockley, in the County
of Kent, 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 :-
This invention relates to the construction of a novel and simple apparatus for
cutting metal pipes or tubes.
In carrying out my invention I employ a cutter or cutters provided with teeth
and arranged so as to be operated by a lever, so that when the cutter or cutters is
or are moved around the pipe with which the said teeth are brought in contact (by
means of a spring or otherwise in combination with the action of the lever) the
pipe will be cut. The edge or edges of the cutter or cutters operates or operate
obliquely against the pipe.
:
In order to enable my invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawing, in which figures 1, 3 and 5
illustrate side elevations and figures 2, 4 and 6 end views of pipe cutters con-
structed according to my invention; figure 7 is a section on line A. B. of figure 5.
Referring to figure 1, a, represents the cutter properly so called which is here
shown of a hook shape; b, b, represent the teeth of the cutter a, which are formed
in an oblique direction so that when the tool is operated they will scoop out the
metal and form a peripheral channel so as to ultimately divide the pipe; c, is the
lever or handle by which the cutter is operated; the cutter a, is jointed at d, to
the lever or handle; e, is a spring for keeping the cutter a, in contact with the pipe
to be cut.
To make use of a cutting tool of this construction the cutter a, is first turned on
its joint so as to allow of the tool being placed over the pipe to be cut; the tool is
then rotated around the pipe by means of its lever or handle c, and the teeth will
by means of the spring d (or other suitable means of pressure) and the lever c, be
caused to enter the metal of the pipe and clear away a channel therein which when
carried to a sufficient depth will divide the pipe.
The construction of the pipe-cutters shewn in figures 3, 4, 5 and 6, is similar to
the tool hereinbefore described and represented in figures 1 and 2 with the exception
that they are different in shape but their action is substantially the same; more-
over the tool shewn in figures 5 and 6 is provided with an additional set of cutting
teeth 61, 61, on the lever or handle c, and the herein before described spring is
dispensed with but it will be obvious that a spring can be employed if found
desirable.
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;
1. A pipe-cutter having its cutting portion or portions formed of a series of teeth

page_text: 2. A pipe cutter in which the cutting portion or portions is or are forced to act
upon the pipe to be cut by means of a lever or levers substantially as hereinbefore
described.
3. The improved pipe cutters hereinbefore described and represented in the
various figures of the accompanying drawing.
