The shoe 5'! is joined together in hinged seg

ments 60 and the shoe can be tightened around
various diameter pipes by means of turning the
handle 6! which is connected tothe shoe through
the line 62, the spring 63 and the pulley 64 which
is pivotally mounted on the frame I. The shoe
5‘! is attached to be pulled along with thema

which can be adjustably positioned in the hook
61 which is rigidly ?xed to a structural member 10
hausted products of combustion are discharged
outwardly through the vent 88. It is thus pos
sible in the device of this machine to maintain
and circulate ‘heated coating ?uid to both the
shoe and the coating head.
Figs. 13, 14 and 15 show‘ a modi?cation of the
machine adapted to coat, then wrap, then coat.
then again wrap a pipe to be processed and in
this machine a coating head 68 insures that the
2| of the frame 1.
second coating is applied in the same manner
as in the modi?cation of the machine described
‘
In this form of the machine the sump is not
heated but a fuel tank 10 is provided to "carry
fuel along with the machine as a reservoir to ?ll
the heated torch which has to be applied to the
sump 20 to heat up any coating material therein
prior to putting the machine in use.
In the form of the invention disclosed in Figs.
6 ‘through 12, inclusive, 2. machine is shown which
is adapted to apply a coating to the pipe 5 by
means of the shoe 51; it is then adapted to wrap
over the coating thus applied by a wrapping
head of similar design as that disclosed in Fig.
3; and the machine is then adapted to apply a
second coating of protective material over the
wrap thus applied through the coating head.
In this machine the driving mechanism and
structural features of the frame and sump are
similar to the modi?cation of the machine here
inbefore described.
It differs in that the sump '
is heated and the piping of the machine is so
adapted to feed coating material to and to cir
culate coating material from both the coating
shoe 5'! and the coating head 68.
In this machine the coating material is ‘taken
by pump 19 from the reservoir tank through the
?exible connection connected to the nipple 5i),
immediately above.
In the device of this machine a sprocket wheel
89 is driven from the transmission 8 through a
transmission system similar to that of Fig. 1 so
as to turn a shaft 90 in a manner to drive both
wrapping heads 9| and 92. In this modi?ca
tion of the machine the coating head 68 serves
the same function as the yoke I l2 to structurally
support the bearings 93 in which the shaft 90
turns to drive both the sprocket 94 to propel the
inside wrapping head 9| and the sprocket 93 to
propel the outside wrapping head 92.
In this machine the sprocket 94 is twice the
diameter of the sprocket 95 so that the inner
wrapping head 9| turns twice as fast as the
outer wrapping head 92 so that‘ a single drum
of wrapping material 96 covers the ?rst protec~
tive coating applied by the shoe while two drums
of wrapping material 91 mounted on the outer
wrapping head 92 overlap in applying the protec
tive wrap over the coating which has been applied
through the coating head 68.
‘ It should be noted that in this modi?cation
the sprockets 94 and 95 are hooded by a guard
I90 which is a rigidly extending member from
the coating head frame 68.

sump through the spout 69. The pump is then
