I, WILLIAM PRIESTLEY of 28 Pickup Street Ince-in-Makerfield near Wigan in
the County of Lancaster, Engineer, do hereby declare the nature of my invention
for an
"IMPROVED MACHINE OR APPARATUS FOR EXTRACTING FERRULES.FROM
LOCOMOTIVE BOILER AND OTHER TUBES" to be as follows:-
A (on drawing attached hereto & marked "C") is an iron cylinder, screwed on
the outside, with an oblong and taper hole through its centre: B, is a large nut to
screw on to A, working loose in the box C: D is a set-screw to keep B and C
together, working loose in the groove I: E and F are two claws working loose at
the points K and L: G is a thumb screw, working on the washer H, and used to
tighten the wedge-bar J.
In order to extract or withdraw a ferrole from a tube, let out the screw
until E. F and J come in contact at the points marked M. & M; insert the claws
and wedge-bar of the machine or apparatus into the ferrule, draw the wedge-bar J
into the position required, the claws at the same time getting hold of, and behind
the ferrule: push the box C, against the end of the tube by means of the nut B,
then work the said nut by means of a screw-key until the ferrule is withdrawn.
Some of the advantages claimed for this apparatus are:-that it is easily worked;
easily repaired; there is no shock or injury given to the boilet or tubes by its use,
as is done when the ordinary rod and hammer are used: and in the case of burst
tubes it is invaluable.

I, WILLIAM PRIESTLEY of 28 Pickup Street Ince-in-Makerfield near Wigan in
the County of Lancaster, Engineer, do hereby declare the nature of my invention
for an "IMPROVED MACHINE OR APPARATUS FOR EXTRACTING FERRULES FROM
LOCOMOTIVE BOILER AND OTHER TUBES" and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
Fig. I on the accompanying drawing represents in elevation, and Fig. II in
vertical section a Machine or Apparatus for the extraction of ferrules from Loco-
motive Boiler, and other Tubes; Fig. III is a plan of the said machine or apparatus;
Figures IV and V represent in plan and elevation a washer; and Fig. VI is a
section taken on the line a b.
The same letters of reference indicate the same parts. The said machine or
apparatus consists of an iron cylinder A, screwed on the outside, with an oblong
and taper hole through its centre; B is a large nut to screw on to A, working loose
in the outer box C; D, D2 are two set-screws to keep B and C together, working
loose in the groove I; E and F are two claws working loose at K and L; G is a
thumb screw or nut working on the washer H and is used to tighten the wedge-
bar J; N is a washer, fitting in the outer box C at P. P³, and to be used when the
ferrule is required to be withdrawn without disturbing the tube; O. 0³, are two
set-screws used to fasten the washer H to the cylinder A.
In order to extract or withdraw a ferrule from a tube, let out the screw
on the wedge-bar J, until E, F and J, come in contact at M, M; insert the
claws E and F and wedge-bar J of the machine or apparatus into the ferrulė;
draw the wedge-bar J into the position required; the claws E and F at the same
time getting hold of, and behind the ferrule; push the outer box C, against the
end of the tube, or against the tube-plate, as the case may be, by means of the
large nut B, then work the said large nut B, by means of a screw-key until
the ferrule is with-drawn.
Some of the advantages claimed for this machine or apparatus are; that it is
easily worked, it is easily repaired, that when used no shock or injury is given to
the boiler or tubes, as is done when the ordinary rod and hammer are used; and
in the case of burst tubes, it is invaluable.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, although I do not limit

page_text: myself to the precise details as described and illustrated, as the same may be varied
without departing from the principle of my invention; but I do claim as my
invention
The improvements in the machinery or apparatus for extracting ferrules from
Locomotive Boiler, or other Tubes, as described and illustrated in the accompanying
Drawing; namely, the combination of the claws E and F, the wedge-bar J, the
cylinder A, the washer N, with the outer box C; the said parts being constructed,
worked, and used for the purpose and substantially as described and illustrated.
