page_text: We, FREDERICK TYERS, of 363 Mansfield Road Plumber, and SANDFORD
BARNSDALE, of Lucknow Drive, Tobacco Manufacturer, both in the Borough of
Nottingham, do hereby declare the nature of this invention to be as follows:-
This invention relates to tools or devices more especially for cutting lead,.
composite, or the like piping.
In carrying out this invention the body of the tool is formed by two levers
pivotted together at a point near their ends, the short extension of each lever
beyond the pivot or fulcrum being formed into jaws of a suitable form.
Mounted concentrically on the pivot or fulcrum of and between the two levers,
is a circular pipe cutter with a plain cutting edge of the usual form, and pivotted
on or in each jaw on independant pivots, are two corresponding cutters. The whole
of the cutters are arranged to rotate with their cutting edges in the same plane,
and the two cutters on one jaw are placed opposite to the two cutters on the other
jaw, and their cutting edges are forced into the pipe by means of the long arms of
the levers.
Small pipes are placed between the edges of the cutter on the pivot or fulcrum,
and the first cutter on each jaw, whilst larger pipes are placed between the edges
of the first and second cutter on each jaw. The number of cutters employed may
be increased or decreased if preferred and their arrangement may also be modified.
In order to held the jaws in their closed position, and give the operator more
power when required, the two jaws may be closed by a screw, or screw and chain,
connected to the jaws or the long arms of the levers. We preferably employ the
latter arrangement as it is found most convenient. The screw passes through a
hole or slot in a lug on the arm or jaw and it is provided on its outer end preferably
with a winged nut, the chain is connected to the inner end of the screw and any
one of its links are passed over a stud or hook on the other arm or jaw.

We, FREDERICK TYERS, of 363, Mansfield Road, Plumber, and SANDFORD
BARNSDALE, of Lucknow Drive, Tobacco Manufacturer, both in the Borough of
Nottingham, 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 more particularly to tools or devices for cutting lead,
composite or like nining

page_text: The invention will be best understood by reference to the accompanying
drawings, in which,
Fig. 1. is an elevation, and
Fig. 2. a plan (showing part of one lever broken away) of a
constructed according to our invention.
Fig. 3. is an elevation, and
Fig. 4. a plan showing an alternative arrangement.

pipe cutter,
In carrying out our invention, the body of the tool or device is formed by two
levers A. AB. B1 (Figs. 1 and 2.) pivotted together by a pivot C. The short
ends A'B' of the said levers are formed preferably as shown.
Mounted concentrically on the pivot C and between the levers is a circular
cutter D provided with a plain cutting edge of the usual form. Mounted also ou
or in the short ends A' B' of the levers are four corresponding cutters, E. E' F. Fi
these cutters are ench mounted on independent pivots G two of them being arranged
on the end of each lever and the corresponding cutters on each lever preferably
opposite to each other as shewa.
The whole of the cutters D. E. E F. and F are arranged to rointe with their
cutting edges in the same plane and they are forced into the pipe by means of the
long arms A. B. of the levers.
Small pipes inay be placed between the edges of the cutters D. E. and E
whilst larger pipes may be placed between the edges of the cutter E. E' F.
and F
In order to hold the cutters in contact with the pipe and give the operator more
power when required, the two ends A B of the levers may be closed by a screw,
or n screw and chiniu I as shown.
The screw passes through a hole or slot in the end A' of the lever A, and it
is provided with a winged uut H on its outer end. The chain I is connected to
the inner end of the screw HI and one of its links engages with a pin or stud 132 on
the end 13 of the lever B.
In an alternative arrangement shown in Figs. 3 and 4 the extreme ends of the
levers A and B may be pivotted together by a pivot C, on which pivot is mounted
the cutter D, as in the previously described arrangement. The cutters EE, F
and are in this case placed at convenient distances between the pivotted and the
free ends of the ievers A and B as shown.
The cutters may in this case be also forced into the pipe and retained in position
by means of a screw and chain engaging with a slot in à lug A' on the lever A, and
a stund B2 on the lever B respectively.
Having now particularly described and ascertained the nature of the said iuven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1. In a pipe cutter the combination with two levers such as AA and B B
pivotted together, of a cutter such as D mounted on the pivot and cutters
such as E E' pivotted on the ends A B of the said levers substantially as
described.
2. In a pipe cutter the combination with two levers such as A A' and B B
pivotted together, of a cutter such as D mounted on the pivot and cutters such
as EEFF pivotted on the ends A B of the said levers substantially as
described.
3. In a pipe cutter the combination with two levers such as A. B. having their
ends pivotted together of a cutter D mounted on the pivot and cutters E EFF
pivotted on the levers A. B. substantially as described.
4. In a pipe cutter the combination with two levers such as A. B. pivotted
together, of cutters such as E E F F pivotted on the said levers substantially as
described.

page_text: 5. The combination and arrangement of parts constituting the complete pipe-
cutter substantially as described and illustrated in the accompanying drawings.
