Engineer 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 centrifugal machines for separating liquids of different
specific gravity and consists in combining with the rotary drum thereof substantially
as hereafter set forth a tube with adjustable mouth pieces for drawing off the heavier
liquid into an annular trough which may be fixed to the rotary drum or be stationary
and apart therefrom and connected to the frame of the machine in such a manner as
to receive the heavier liquid as it flows from the drum The trough may be provided
with an outlet so that the machine may work continuously
The accompanying drawings illustrate the improvements as applied to a machine
having two centrifugal drums rotating on a horizontal axis
Fig 1 is an end elevation showing the machine in operation
Fig 2 is the same out of action
Fig 3 is a sectional side view, the drum on the left being out of action that on the
right in action
Fig 4 is a sectional plan view thereof
Fig 5 is an enlarged sectional view of the pipe for leading off the heavier
liquid
Fig 6 show a mouth piece thereto
A is the frame carrying in bearings a the horizontal shaft e driven by the pulley b
and carrying on its ends the drums S S¹ respectively The drums are preferably of
the shape shown open centrally on the outside for receiving the liquid to be treated
and drawing off the lighter liquid
The liquid to be treated is fed to a swivelled tank or receiver G whence a pipe d
carries it into the drum The tank is swivelled so that the pipe d may be moved into
and out of the drum through the central opening thereof On the inner wall of the
drum opposite the central opening is an annular ledge h forming a trough receiving
the liquid, which a pipe p carries to the outer parts of the drum so that the incoming

may not disturb the lighter product already in the drum nearer to the axis thereof
carry off the lighter liquid in a sleeve carrying the same at a suitable angle is a pipe q
having a sharp nozzle and adjustable longitudinally in the sleeve so as to receive and
carry off the lighter liquid as the drum revolves
The sleeve carrying the pipe q is preferably formed in one piece with the annular
trough F which is shown in the present machine as hinged with the tank G so as to
be movable therewith, the trough F is concentric with the drum and surrounds the
opening in the latter, it is in this case stationary and does not revolve with the drum, it
is provided with an outlet p¹ In the centrifugal drum is the pipe t extending from the
outer part of the drum towards the axis thereof and terminating near the central
opening in the drum traversing the wall of the drum and opening into the trough F
so that the liquid issuing therefrom is caught by the trough To control the emission
of the heavier liquid the outer end of the pipe t (Fig 5) is screw threaded on the
inside or otherwise, contrived to receive a mouthpiece o having a central perforation
so that the outlet of the liquid may be controlled according to the size of the
perforation in the mouthpiece o
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1 The combination with a centrifugal separator of a pipe t substantially as set
forth and mouth piece o thereto for the purpose described
2 The combination with a rotary centrifugal drum of a stationary annular trough
arranged in relation thereto substantially as set forth
3 The combination of a rotary centrifugal drum having a horizontal axis and a
central opening thereto, a pipe t swivelled tank G with pipe d trough F and pipe q
substantially as and for the purpose set forth
