The present invention ‘comprises modi?cations
of that described and illustrated in my pending
application, Serial Number 19,390, ?led May 2,
1935, patented March 9, 1937, Patent No. 2,073,
9 139, for improvements in an Apparatus for treat,
(cl. ctr-i)
of operation. If the valve 46 be turned oil’ with
the valve at open, the steam under pressure will,
enter the container by means of line‘ H and will
force compound 88 into the main line bi by means
at line W, T-connection 49 and line M.

The other method may be employed by closing
The invention and its modi?cations will be‘ valve 49 and opening valve lib whereupon the
ing steam heating-systems.

‘ more fully described in the accompanying speci
?cation and drawing in which:-+

The drawing shows a side view partly in sec-
' tion and partly in elevation of a compound heat
ing and injecting installation embodying my in-,
vention.

In the drawing, the line 4| leads directly into
15 the compartment 42 at a low point thereof‘ior
the purpose of discharging steam under pres
sure therein. Said line 4| is provided with a
shut-oil valve 42 which may be closed to allow
the- passage of steam‘ through the‘ horizontal line
20 M, which is coupled to line 4| by means 01' T
A connection 45 and which has a shut-oi! valve 46
interposed therein adjacent to line“. Line 41
communicating‘ with the container 42 at‘ 48 there
or provides means of egress for the steam and
25 compound mixture and is joined to line 44 by
means of the T-connection 49. On the low side
» 01' said T-connectlon 49 the line 44 has interposed
‘therein the check valve 50 and leads to the main
line 5! by means of the T-connection 52. A line
'30 as is coupled to the main line 5| by means of the
T-connectlon 54 and communicates directly with
the coil 55 in container 42. Various elbows i9
and unions 51 are interposed in the lines where
they are necessary.

steam will pass through line 4t, the T-connection
49,‘ the check valve 64 and back into line 9i by
means of coupling 52 and ‘in so doing will convert 10
the line 41' into a siphoning tube,~drawing the
mixture by this means into the main line ti. As
in the ?rst form of the invention, a heating coil
95 is employed to pre-heat the treating solution
and this may be coupled to either the high or low 15 I
side of the main line.
The device is capable of various modi?cations
in structurev and design without departing from
the spirit of the invention, all within the scope
of the appended claim.

Having thus described my invention, what I
claim as new and desire to secure by Letters Pat
ent oi’ the United States, is:-
-
‘
In combination with a steam heating system
having a reducing valve therein, a container for 25
pipe treating compound, a line from the high
pressure side oi’ the valve communicating with
the container, a heating coil in said container, a
line from the low pressure side of said valve cou
pled, with'the coil, and a discharge line leading 30
‘from said container to the heating system where
by the compound will be forced into the pipes‘
thereof.

In use, this apparatus is capable oi two modw
o'rro‘ J. cum-r12.
