GENTRIFUG-AL VACUUM-PUMP.
Application filed August 18, 1919.
To all whom it may concern:
Be it known that I, VICTOR'ROSENHAGEN, a citizen of the United States of America in the county of vented a new and useful Improvement in Centrifugal Vacuum-Pumps, of which the following is a specification.
The object of my invention is a pump for creating a vacuum by means of the centrifugal force of water which is fed to the pump and is thrown therefrom by the rotation of the pump, the vacuum being created by means of the water ejected therefrom.-
This object is attained by the means described in the specification and illustrated in the accompanying drawings in which Figure 1, is a central sectional View of a vacuum pump embodying my. invention taken upon line 11 of Fig. 2.
Fig. 2, is a sectional view taken upon line 2-2 of Fig. 1. I
Fig. 3, is a detail view upon an enlarged scale, of the air discharge tube.
The pump casing comprises shells at, a, which are connected together around their peripheries by a series of bolts a and between which the rotor B is located.
The rotor comprises a wheel composed of two circular disks, Z), 6, between which there is located a series of spiral shaped tubes, 6 which extend from the periphery of the disks to the central opening 5 thereof. Tubes, 6 are preferably spaced at uniform distances apart, and terminate at their inner and outer ends at equal distances apart.
Disks 6, b, have central annular collars a (1*, of the casing a, a. 6 there is mounted a cylindrical head 03, which is secured to the casing 11. This head is formed into an air chamber, d and a water chamber, d the former of which has extending into it an air pipe, 03 and the latter of which has extending into it a water pipe 03*. Chambers, 03', d are separated by a diaphragm, d".
Collar 72*, has extending into it flange e of a sleeve E within which the spindle B is rotatablymounted.
The walls of the casing have formed in them a peripheral channel a which extends partially around the Specification of Letters Patent.

rotor. The balance of the walls of the casmg, exceptlng at recess, a, contact snugl W1th the periphery of the rotor. Channe a at its outer end communicates with a discharge tube, F. Between the discharge end, of, of channel, a and its inner end there IS a recess (H, in the walls of the cas- 1ng, which forms an air chamber and which communicates with an air outlet pipe, a a", which communicates with pipe F.
In use the water pipe, at, is connected to a water reservoir, not shown, which is at a higher level than the rotor B, andthe pipe, (Z3, is connected to the vessel in which it is desired to. create a vacuum.
Then the rotor is rotated rapidly as for instance. at a speed of 1500 revolutions per minute and in the direction'of the arrow indicated in Fig. 1. Water which rises in the tubes, 6 when ends are contacting with the walls of the casing, is thrown forcibly from the tubes into the channel, a when the ends of the tubes are registering with the channel a The centrifugal force of the water ejected from the tubes will cause the air to be drawn from the chamber, d and the tubes (i It will be seen that-when the outer ends of the tubes, 6 register with the channel, a, their inner ends register with the chamber 03 and that when the outer ends of the tubes, 6 contact with the walls of the casing, their inner ends communicate with the chamber, 0Z After the ends of the tubes d pass by the channel, 01 water a ain enters ber, (2V. T e air in the tubes is forced by the water into the chamber, a, and thence by pipe, a", into the pipe F.
he water ejected into the pipe, F, is carried thence into the reservoir not shown. Thus the height of the water in the reservoir is kept practically constant.
What I claim is:
. In a centrifugal vacuum. pump the combination of a casing, a rotor mounted in the casing, the casing having in it a discharge channel which extends throughout a portion only of the interior surface of its eripheral-wall, said casing contacting W1th the periphery of the rotor at points between the ends of the channel, the rotor having at its center a water chamber and an air chamber, and a series of tubes extending from its center to its periphery, a water vchamber and an air supply tube connecting with the air chamber, the inner ends of the tubes being adapted to register with the.
water chamber while their outer ends are closed by contact with the casing and to register with the air chamber while their outer ends are open to the discharge channel. 1
In testimony whereof, I have hereunto 10 subscribed my name this 15th day of August, 1919.
VICTOR ROSENHAGEN.
