PROVISIONAL SPECIFICATION.
Apparatus for use in Turning or Facing the Ends or Flanges of
Pipes and similar articles in Lathes.
We, DONALD BARNS MORISON and JOHN MCADAM, both of Hartlepool
Engine Works, Hartlepool, in the County of Durham, Engineers, do hereby
declare the nature of this invention to be as follows:-
Our invention consists of an improved apparatus for turning or facing the ends
or flanges of pipes and similar articles.
An apparatus constructed according to our invention consists of two or more
suitably formed frames or carriers which may be keyed or otherwise secured to a
mandril, or which in cases where large numbers of pipes or similar articles of one
length have to be turned or faced, may be cast, or otherwise formed solid with the
central portion.
The said frames or carriers are formed with suitable recesses for receiving the
pipes or other articles which are so placed that the flanges or other parts to be
turned or faced are at right-angles to the centre-line of the lathe, the said pipes or
similar articles being secured to the frames or carriers in a convenient manner and
being placed at equal distances from the centre. In this way a great number of
small pipes or similar articles may be placed in the apparatus at one time. The
apparatus with the articles to be operated upon may then be placed in a turning
lathe and one or both ends of all the articles turned or faced at the same time.
If the length of the lathe bed allows, more than one set of articles may be
operated upon at the same time by having four or more frames or carriers attached
to or formed with the central part. In this case the four ends may be operated
upon by three slide rests the central rest being provided with two tools which are
utilized to face one end of each set.
The number of sets of articles operated upon at one time is only limited by the
relative length of the articles and of the lathe-bed.

COMPLETE SPECIFICATION.
Apparatus for use in Turning or Facing the Ends or Flanges of
Pipes and similar articles in Lathes.
We, DONALD BARNS MORISON, and JOHN MCADAM, both of Hartlepool
Engine Works, Hartlepool, in the County of Durham Engineers 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:-
Our invention consists of an improved apparatus for turning or facing the ends
or flanges of pipes and similar articles.
An apparatus constructed according to our invention consists of two or more
suitably formed frames or carriers which may be keyed or otherwise secured to a
mandril, or which in cases where large numbers of pipes or similar articles of one
length have to be turned or faced, may be cast, or otherwise formed solid with the
central portion.
The said frames or carriers are formed with suitable recesses for receiving the
pipes or other articles which are so placed that the flanges or other parts to be

page_text: turned or faced are at right-angles to the centre-line of the lathe, the said pipes or
other similar articles being secured to the frames or carriers in a convenient manner
and being placed at equal distances from the centre. In this way a great number
of small pipes or similar articles may be placed in the apparatus at one time. The
apparatus with the articles to be operated upon may then be placed in a turning
lathe and one or both ends of all the articles turned or faced at the same time.
If the length of the lathe bed allows, more than one set of articles may be
operated upon at the same time by having four or more frames or carriers attached
to or formed with the central part. In this case the four ends may be operated
upon by three slide rests the central rest being provided with two tools which are
utilized to face one end of each set.
The number of sets of articles operated upon at one time is only limited by the
relative length of the articles and of the lathe bed.
In order that our invention may be fully understood we append two sheets of
explanatory drawings.
Figure 1 shews the apparatus, in longitudinal section, in position between the
centres of a turning lathe.
Figure 2 shews an apparatus suitable for facing two sets of pipes or similar
articles at the same time.
Figure 3 is an end view of the apparatus, and,
Figure 4 is a longitudinal section of another form of the apparatus having the
frames or carriers cast, or otherwise formed solid with the central portion.
In Figure 1, A is the central mandril, and B B are two frames or carriers keyed
or otherwise secured to the mandril. The pipes or other articles C C to be turned
or faced at the ends are placed in recesses formed in the frames or carriers (shewn
clearly in Figure 3) and held in position by suitable covers D, preferably hinged
as shewn in Figures 2 and 3. In order to adapt one apparatus to different sized
articles, bushes E E of suitable size, in halves, may be fitted into the recesses.
The apparatus shewn in Figures 2 and 3 has two sets of frames or carriers B B BB
of precisely the same construction as already described. The form of the covers D
is clearly shewn. Double hinges Fare secured to the frames or carriers by the
screws G. The covers D being thus hinged on one side admit of the articles being
quickly placed in or removed from the apparatus. Screws H are provided for
screwing down the covers tightly.
Although we prefer the above details of construction we do not confine ourselves
to them but may use any equivalent device.
The details of the apparatus shewn in Figure + are similar to those previously
described. This form is useful where a very large number of articles of the same
length have to be turned.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
(1) Apparatus for turning or facing the ends of pipes or similar articles con-
structed and operating substantially as illustrated and described.
(2) The forms of apparatus for turning or facing the ends of pipes or similar
articles shewn in and described with reference to Figures 1. 2 and 3.
(3) The form of apparatus for turning or facing the ends of pipes or similar
articles shewn in and described with reference to Figure 4.
Dated this 14th day of September 1891.
