Improvements in or relating to Facing and Coning Apparatus for
Pipes and the like.
I, JOB POTTER, of 81, Carver Street, Sheffield, in the County of York,
Mechanic, 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 facing and coning apparatus for pipes and the like its
object being to dispense as far as possible with the inconvenience experienced and
excessive labour required when pipes are faced or coned by the ordinary apparatus.
The improved apparatus according to this invention is a self-contained tool and
after only clamping and fixing the pipe within the said tool I can either face it or
cone it, with ease, and with the same cutter. These operations can be effected in
the place in which the pipe may happen to be fixed for the tool can easily be
carried by the workman and fastened on the pipe to be operated on.
Fig. 1, is a side elevation of one construction of improved apparatus according
to this invention.
Fig. 2, is a front elevation of the same.
Like letters indicate like parts throughout the drawings.
In constructing the apparatus I provide a plate or cross-head A having sides B
screwed on the same and provided with suitably shaped jaws C for clamping the
pipe (such as D) to be operated on; the sides B being screwed to the cross-head A
in such manner as to allow them a little play and enable the jaws C to open
and close at will and on a projection of the sides B I arrange a clamping arrange-
ment E with screw or screws F so that the clamp can adjust the position of
the jaws C and hold the pipe D tight. On the aforesaid cross-bar A centrally
I arrange a screwed bush G tapered as shown or having a collar at its underside
and in the same bush G is contained a screwed barrel H with a cross-head or
lever J at its upper end for adjusting the pressure of the cutter K on the pipe D.
Extending through the screwed barrel H is a spindle L which passes through
a sliding guide boss M between the sides B the spindle L having a conical boss L¹
and parallel projection L2 to fit either into the pipe D direct or by means of
a bush N and through the said conical boss L', I make a slot O for receiving the
cutter K, one side of which is used for cutting conical and the other for square
faces as is indicated in Fig. 2, by the difference in form of the upper and lower
sides. The spindle revolves in the bush, which is placed in the pipe to steady
it by being preferably split and holds itself on to the internal sides of the pipe.
On the extreme end of the spindle L at the top I form a fixed collar P and a
square head R for turning the spindle L with a spanner or wrench so as to rotate
the cutter K for cutting the pipe D whilst the pressure is put on the cutter K by
the cross-head or lever J of the screwed barrel H which passes on the sliding
guide with boss M and forces the conical boss L' with spindle L and cutter K
against the face of the pipe D or releases them as required for the sliding
guide with boss M rises and falls with the screwed barrel H while at the same time
the pipe D is clamped in the jaws C tight.
If desired ball bearings may be used to take the friction of the hearings.
This invention is not limited to the particular combination and arrangement of
parts hereinbefore described by way of example which may be varied without
departure from this invention.

page_text: Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. In pipe-facing or similar apparatus the combination with a clamp such
as A C of an adjustable barrel such as H and a rotatable cutter-spindle L arranged
to be forced end wise by the barrel with or without the guide M substantially
as and for the purpose described.
2. In a pipe-facing or similar apparatus of the kind described the combination of
a spindle and a tool such as L2, with or without a bush N substantially as and for
the purpose described.
3. A pipe-facing tool so formed that its opposite sides can be used for cutting
faces of different forms substantially as described.
4. The combination and arrangement of parts constituting a complete pipe-
facing apparatus substantially as described and illustrated in the accompanying
drawings.
Dated this 12th day of September 1896.
