Improvements in Tools for Cutting Pipes and the like.
We, ARTHUR EDWARD CROAGER and ALFRED ERNEST CROAGER, both of Link
Street Works, Homerton, in the County of Middlesex, Mill and Engineers'
Furnishers, 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:-
According to this invention the handle carries two pairs of rollers means being
provided whereby one pair can be caused to approach the other and grip the pipe or
the like. The cutting tool is placed between the rollers of one of the pairs means
being provided for feeding it forward.
Figure 1 is a side view partly in section of a tool constructed according to this
invention. Figure 2 is an edge view at right angles to Figure 1. Figures 3 and 4
are sections on the line - Figures 1 and 2 looking to the left and right
respectively.

a is the body and bb are a pair of rollers mounted on shafts bb working in
stationary bearings or holes in the body. ce are a second pair of rollers mounted
on shafts cc working in bearings or holes in a crosshead d fixed to the longitudinal
Each of the rollers b and c appears in the drawings as a double roller but
as the two parts act as a single roller they are so described. The bar e is free to
move longitudinally in the body but is prevented from turning by the pin al
engaging with the slot e¹ in it. The end of the bar has a left hand screw thread e
on it engaging with a similar thread inside the hollow end of a bar f and this
bar also has a right hand screw thread on the outside of its end engaging with a

is the tool or cutter which is
pivotted by the pin g' to the cap or sleeve h. This sleeve fits on the stem j' which
forms part of the bar j. The end of the bar has a screw thread upon it engaging
with a similar screw thread in the hollow end of the body a. The stem is
grooved to receive the pin projecting inwards from the sleeve so that the bar j
can turn relatively to the sleeve but carries the latter and the tool to and fro with
it. is a lubricator for supplying oil to the tool, it is omitted in Figures 2 and 3.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare that what
we claim is:-
1. The combination of two pairs of rollers, means whereby one pair can be caused
to approach the other and a cutting tool between the rollers of one pair.
2. Tools for cutting pipes and the like substantially as described and illustrated
in the drawings.
