A PORTABLE HAND TOOL FOR FACING UP THE FLANGES OF STEAM PIPES AND OTHER PURPOSES
Year: 1884

page_text: JOHN TYSON 9 Grafton Place Euston Square London, N.W. Engineer do hereby
declare the nature of my Invention for A PORTABLE HAND TOOL FOR FACING
UP THE FLANGES OF STEAM PIPES AND OTHER PURPOSES to be as follows:-
1st A conical headed bolt, (A) upon the head of which slides a divided expanding
disc, (B) for the purpose of fixing into the ends of pipes, upon the shank of the
bolt is a loose sleeve, (C) a washer, (D) & a nut, (E) so that when the nut is
tightened up the disc expands & becomes firmly fixed in the end of the pipe to be
operated upon, at the same time the loose sleeve is fixed, and prevented from
revolving.
2nd Upon the loose sleeve is fitted a revolving arm (F) having a slot (G) at right
angles to the sleeve, in which slides the tool box (H) & a projection or boss (I)
upon which the handle (J) is put.
3rd The tool box being worked either way along the slot by means of a
screw (K), upon one end of which is fixed a bevel wheel (L).
4th The handle of the machine is fixed to, or forms, a revolving stud (M) on
the end of the revolving arm, upon the revolving stud is fixed two bevel
wheels (N, O) either of which may be in gear with the wheel upon the screw,
according to which way the tool box is desired to travel.

page_text: I JOHN TYSON of 9 Grafton Place, Euston Square in the County of Middlesex
Engineer do hereby declare the nature of my Invention for A PORTABLE HAND
TOOL FOR FACING THE FLANGES OF STEAM PIPES AND OTHER PURPOSES and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :—
[The top Drawing represents an elevation partly in section, bottom Drawing
represents a plan of the machine].
1st A conical headed bolt [A] upon the head of which slides the three pieces
[B, B, B] for the purpose of fixing into the ends of flanged pipes, or the article the
machine is required to operate upon. On the shank of the bolt is a loose sleeve [C]
a washer [D] and a nut [E] so that when the nut is tightened up, the
pieces [B, B, B] open out and become firmly fixed in the end of the pipe, or article,
at the same time fixing the loose sleeve [C] and prevent its revolving. The
pieces [B, B, B] are held against the cone by the elastic band [P].
2nd Upon the sleeve [C] is fitted the revolving arm [F], having a slot [G] at
right angles to the sleeve, in which slides the tool-box [H] and having a
projection [I] in which the handle [J] revolves.
3rd The tool-box [H] being made free to work either way along the slot [G] by
means of the screw [K] upon which is fixed the bevel wheel [L].
4th The handle of the machine revolves in the projection [I] and is connected
to the spindle [M] upon which is fixed the two bevel wheels [N, O] either of which
may be in gear with the wheel [L] upon the screw, according to which way the
tool-box [H] is desired to travel along the slot [G].
5th This machine may be made in different sizes and proportions than is shown
by the Drawings. The handle may be made longer so that both hands may be
applied, and the expanding pieces may be made to suit any size of pipe, or other
article as desired, the said expanding pieces being suitably guided at angles of 120°
with each other, by pins fixed in the loose sleeve, pins fixed in the cone head of
the bolt, or guide plate at the base of the cone, I prefer pins fixed in the sleeve as
most simple and efficient.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is:
1st This method of firmly fixing the sleeve [C] or axis of rotation, by the cone
headed bolt [A], [with its nut & washer] expanding pieces [B, B, B], and elastic
band [P].
2nd The way in which the tool-box is made to move along the slotted arm by
gearing through the handle, so that the one operation of turning the machine
around by the handle, also causes the tool to advance to its work, in either direction
as required along the slot, by means of the screw [K], wheel [L] and the two dead
wheels [N, O] in connection with the handle [J].
3rd The entire design and construction of the machine as described in the above
particulars and shown by the Drawings herewith.
Dated this 15th day of August 1884.
