COMPLETE SPECIFICATION.
Improvements in Appliances for Use when Making Pipe or the
like Joints.
We, JOHN WOOD 7 Cornwall Road South Hackney N.E., Boot Machinist, and
WALTER CLARK 16 Sidworth Street Hackney N.E., Plumber, 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 improvements in appliances for use when making pipe.
or the like joints and the same is carried out as follows:-
We provide a mandrel having a slot or slots at each end, of suitable material.
and being bored or pierced longitudinally so that a rod or bar may be passed
through same one end of which carries a wedge shaped piece and the other end is.
provided with a screw thread upon which a thumb screw or nut engages; which.
acts upon a second wedge which is thus forced in a slot or slots in the end of the
mandrel and which causes the one end of the mandrel to expand against the inside-
of the pipe and at the other end to expand upon the socket or the like to be soldered
which is placed upon same, thus retaining the socket or the like in contact with the
pipe or the like when making a soldered or wiped joint.
By releasing the nut or thumb screw after the joint has been made the appliance-
can be removed from the pipe or the like.
A clip of any suitable forin may be employed to maintain the screw cap or union
in position so as not to interfere with the process of soldering when making the
joints.
Referring to the annexed drawings
Figure 1 is a sectional side elevation of my invention.
a is the pipe upon which the joint is to be made at the end of same and the
socket or junction piece 6 is held in position by means of the expandable mandrel c
having slots d in same in which wedge shaped pieces engage namely e and f, the
wedge shaped piece e being attached to the rod or bar h and the wedge shaped
piece is forced into the slotted end of the mandrel c; this action causing the two
wedge shaped, pieces to expand the ends of the mandrel which thus engages or
presses upon the inside of the pipe and the socket or junction piece thus retaining
same in position by the thumb screw or nut g which engages on the screw thread ¹
upon the spindle, rod or bar h so that the wedge f is forced by screwing the nut g
upon the spindle, bar or rod h which passes through the expansible mandrel; thus
retaining the socket and pipe a to be fixed together in position; either by soldering
or what is known as a wiped joint.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. In means for retaining or holding a socket piece or pipe against another pipe
when soldering or making a joint to connect them together, a screwed rod passing
through a mandrel having split or slotted ends, one end of the rod carrying a wedge
shaped piece of metal or the like which engages in the slotted end of the mandrel ;.

page_text: a wedge having projections which engage upon the screwed rod and enters the slot
in the other end of the mandrel, so as to cause the wedges to expand the ends of the
flexible mandrel by means of a thumb screw or nut upon said screwed rod.
