PROVISIONAL SPECIFICATION.
Novel Portable Apparatus for Turning, Facing, Cutting, and
Screwing Pipes, Tubes, and the like.
I, WILLIAM WRIGHT, of 111 Earlsfield Road, Wandsworth, in the County of
Surrey do hereby declare the nature of this invention to be as follows:-
My invention relates to the novel arrangement and combination of a portable
apparatus for turning, facing cutting & screwing pipes, tubes &c. by means of a
travelling, revolving, tool holder, and also a tool holder revolving only; and in the
means which adopt for raising and lowering the tool for cutting and facing
purposes.
The apparatus in accordance with my invention consists of two tubes of any
suitable material having a screw inside the first tube A, which is made to revolve
on a screw cut on the outside of the second tube B. The pitches of these screws
must coincide or correspond with the pitch of the screw to be cut. A tightening
screw and liner C are provided to hold tubes A and B fast whilst the tool box
revolves free for cutting and facing. The wedge clips D are fixed on the pipe,
tube, or the like to be operated upon by a spring or other suitable means.
The above referred to tube B is bored taper, to allow of its fitting on the
wedge clips D and when forced on firmly holds the work. The first above
referred to tube A travels upon the inner tube B. The former has a piece on
the end turned and grooved suitable for carrying 1 or more tool box holders E; the
tool box F, rises or falls by means of a screwed or unscrewed socket G, which is
held in position by a gland G2 carrying a handle by which the power is com-
municated for hand work, the apparatus can be arranged to work by any other
suitable power but is especially adapted to work by hand. The tool box F, tool
box holder E, and the tools are held in position by tightening the two gland nuts
on G2 or one only, when operating. The tool is set and held in position by the
small eye bolt J, shewn on the top of the tool box for cutting off or facing. The
combined set screw holder bolts H, at the back of the tool box are made reversible,
one end to hold the box firm whilst turning or screw-cutting, the other ends when
inverted are made to run in a groove, quite loose for turning or cutting off pipes
and facing the ends, also for turning and facing other articles. The projecting
piece at the bottom directly opposite the tool, fulfils two functions namely that of
securing the machine to the pipe or other articles to be operated upon and as a
steady" whilst the work is being done by means of the steadying piece it carries
held by the thumb screw J.

1, WILLIAM WRIGHT of 111 Earlsfield Road, Wandsworth, in the County of
Surrey, 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 :-
My invention relates to the novel arrangement and combination of a portable

page_text: apparatus for turning, facing, cutting and screwing pipes, tubes &c. by means of a
travelling, revolving tool holder, and also a tool holder revolving only; and, in
the means which I adopt for raising and lowering the tool for cutting and facing
purposes.
And in order that my invention may be more fully understood, I make reference
to the drawings filed with my Provisional Specification, in which
Figure 1 shews a longitudinal section, Figure 2 a plan view and Figure 3 an end
elevational view of my improved device.
The apparatus according to my invention consists of two tubes of any suitable
material, having a screw inside the first tube A, which is made to revolve on a
screw, cut on the outside of the second tube B; the pitch of these screws must be
the same as that of the screw thread to be cut. A tightening screw and liner C
and the necessary wedge clips D which may be held together by a spiral spring or
other suitable means for holding the machine to the work to be operated upon.
The first or largest tube A, has a piece on the end turned and grooved, suitable
for carrying one or more tool box holders E; the tool box Frises or falls by
means of a screwed or an unscrewed socket G, which is held in position by a gland
carrying a handle by which the power is communicated for hand work. The
apparatus according to my invention can be arranged to work by any other suitable
power, but it is especially adapted to be worked by hand. The tool box F, tool
holder, and the tools, are held in position by tightening to two gland nuts, or one
only when operating. The tool can be set and held in position, by the small eye
bolt J, shewn on the of the tool box, for cutting off or facing articles.
The combined set screw holder bolts H, at the back of the tool box, are made
reversible; one end serving to hold the box firm whilst turning or screw cutting;
the other ends when inverted, are caused to run in a groove quite loose when
turning or cutting off pipes and facing their ends; as also, for turning and facing
other articles. The projecting piece M seen in the drawing (Figs. 1 & 3) at the
bottom and directly opposite the tool, serves to fulfil two purposes or objects,
namely firstly for securing the machine to the pipes or other articles to be
operated upon; and secondly as a "steady" whilst the work is being done, by
means of the steadying piece N carried by said projecting portion M and which
(steadying piece) is held by the set-screw K.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
First. The novel portable apparatus for turning, facing, cutting and screwing,
pipes, tubes and the like, substantially as herein described and shewn.
Second. In the apparatus referred to in the preceding claim, the arrangement
and combination of a portable device for turning, facing, cutting, and screwing,
pipes, tubes and the like, consisting of a travelling revolving tool holder and also
a tool holder revolving only, and the method adopted for raising or lowering the
tool and holding it in position for cutting, turning or facing purposes, and the
mode of securing the apparatus aforesaid, to the work to be operated upon, all
substantially as herein described and shewn in the accompanying drawings.
Dated this 29th day of January 1894.
