Application March 2, 1938, Serial'No. 193,391
4 Claims.
My invention relates to fastening apparatus
andv has particular relation to apparatus incor
porating a tube which is to be securely mounted
in a frame and to the ends of which torques are
to be applied.
The present application constitutes an im
provement of application for. Electro-chemical
apparatus, Serial No. 173,603, ?led November 9,
11937, to George A. Hazen, and assigned, by
mesne assignments, to the C. K. Manufacturing
The above-mentioned application is directed to
a cleaning system for colloidal suspensions, in
which the cleaning takes place in a tube mechani
(01. 285-1)
larity in the appended claims. The invention,
itself, however, both as to its organization and
its method of operation, together with additional
objects and advantages thereof, will best be
understood from the following description of a '5
speci?c embodiment when read in connection
with the accompanying drawing, in which‘

colloidal liquid ?ows. ' The tube is mounted in a
present application will be found in the above
container and a potential is supplied to the liquid inentioned Hazen application, and except for the
in the container through a terminal projecting
laterally from the tube. I have found, in mount
2 a. ing the tube in the container in a manner taught
by the prior art of which I am aware, that'when
the tube is coupled to the supply coil and is sub~
j'ected to a torque applied in tightening the
coupling, it turns about its axis to a considerable
2% extent. By the turning the lateral terminal is
displaced and the electrical connection is broken
or otherwise deleteriously affected.
It is; accordingly, an object of my invention to
provide a mounting arrangement for a tubular
30 element that shall prevent its turning about its
axis when it is subjected to torques.
Another object of my invention is to provide a
simple and inexpensive mounting for a tubular
element which, when used, shall prevent the
turning of the tubular element about its axis
when torques of substantial magnitude are ap
plied anywhere to the tubular element.
More speci?cally stated, it is an object of my
invention to provide a contrivance for mounting a
40 tubular element in a container in such manner
that when the tubular element is subjected to
torques, its position as regards its longitudinal
axis shall not change.
According to my invention, I provide a collar
45 which is secured to the tubular element by weld
ing, soldering or sweating. The external sides
of the collar are of such geometric structure that
they engage the walls of the container when the
tubular element is in position. Torques applied
to the tubular element are counteracted by the
engagement of the collar with a wall of the con
tainer and the tubular element is thus prevented
from turning.
The novel features that I consider character
55 istic of my invention‘ are set forth with particu
speci?c features involved in the present inven
tion,pwill be discussed only lightly’ here. For a
more detailed discussion, reference is made to the 20
said Hazen application.
‘ ’
The apparatus comprises, in general, one‘or
more tubular elements 5, each of which is coupled
at its ends tothe coil ‘I through which the col
loidal liquid subjected to the treatment passes; 25
Speci?cally, the Hazen invention applies to‘ the
treatment of malt liquids, such as beer, and in
this case, the tubular element 5 is attached to
the beer coil 1 extending from the beer barrel
(not shown) to the spigot (not shown) at the 30
dispensing bar.
The tubes 5 are mounted in a
suitable rectangular container 9 and extend
through openings II in the side walls l3 of the
container. The coupling to the coil 1 takes place
outside of the container 9 and adjacent to the 35
side walls I3.
The coupling devices l5 used are described in
detail in the above-mentioned Hazen application.
Each device includes a hexagonal tightening nut
I‘! which is screwed on to the threaded ends I9 40
and 2! of the tubular element 5 fastening the
terminals of the coil 1 to the tubular element in
such manner thatino leakage of the malt liquid
takes place.
Within the tube 5, a metallic strand (not 45
shown here) for applying a potential to the liquid
is provided, as described in the Hazen applica
tion. The strand is connected to one output tap
23 of a supply transformer 25 through an in
sulated terminal 21 projecting laterally from the 50
tubular element 5. The other output tap 29 of
the transformer is grounded to the container wall
l3 and thus a difference of potential is impressed
on the liquid flowing through the tube 5.
In the apparatus constructed in accordance 55

invention, secured to the container. When the
nuts, I‘! at the end of the tubular element 5 are
now tightened, the. sides 33 and 35 of the collar
press against the wall 31 and the c0ver'39 of the
container and prevent the tubular element from
turning on its axis.
Of course to withstand the torque applied, the
collar 3| should be rigidly secured to the tube 5.
Where’ the’ torque will always be relatively small,
the collar 31 may be fastened simply by welding
or'soldering. However, in general, the torque ap
plied" may be large, and it is, therefore, desirable
_ that the collar 3| be sealed to the tube 5 by sweat
applied thereto.
