T0 Aall whom t may concern J Be it known that 1, BENJAMIN Siiiniroiin,l

Jr., a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and ,useful,Improvements in Suction and Pressure Creating Apparatus, of`which the following is a specification.

This invention relates to improvements in suction and one of the objects of the saine is to provide an improved apparatus of this character for creating a suction in a chamber or passage and which apparatus also operates to create a pressure.

A further obj ect is to provide an improved apparatus of this character having means whereby the 'enforced circulation of a liquid will cause or create a suction or vacuum in a Chamber or passage. l

To the attainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the fea-tures of novelty in substantially the construction, combination and arrangement of the several parts hereinafter-more fully described .and claimed and'shown in the accompanying drawing illustrating this invention, andin which:

Figure 1 is a detail vertical sectional view jof an improved apparatus of-this character,

constructed in accordance with the princi'- ples of this invention.

Fig. 2 is a top plan view of the parts shown in Fig. 1 and with parts broken away.

Referring more particularly to the draw-- ing, the numeral 10 designates generally a tank or receptacle within whichaksupport 11 is rotated by means ofa suitable shaft 12. This support 11 is preferably hollow and is provided with a plurality of outlets'opening through its periphery. The outlets are preferablyin the form 4of nozzles 13 discharging substantially at a tangent and having an inlet 14 within.' the support. If desiredthe nozzle 13 maybe reduced as at 15, intermediate' its ends. The `suppoit is provided with a depending tubular portion 16 having an inlet 17 which`is submerged within the liquid 18 inthe of radially disposed `arms or tubular passages 19 located within the hollow support 11. These arms y or passages 19 may be of any desired configuration or shape and are provided with reduced extremities 20 which terminate adpressure creating apparatus andv 'f will be entrained around the outside of the .or members 19 -are once tank and com-4 jacent the inlets 11 of the respective. nozzles 13 to discharge thereinto and the'exterior diameter of the arms 19 is considerably less than the diameter of the nozzle, so that when the liquid is discharged from the arms or tubular members 19 by centrifugal force during the rotation of the support 11, and which support rotates above the liquid 18, a suction will be created in the hollow support and through the nozzle 13 to entrain iiuid therethrough anddischargc the saine into the tank 10 with the liquid discharged from the arms 19. When thus discharged the uncondensed fiuid will rise in the tank whilethe liquid will be precipitated. Arranged witliin the hollow support 11 and above'the arms 19 is a partition 21,which cooperates with the wall of the support to form a chamber above the arms 19 and the partition 21 the periphery of the support; The chamber 22thus formed within the support has com* munication with a depending tubular portion 2 3 which extends through the tubular portion 16 of the support and is of a diam eter considerably smaller than the passage 16. This tubular portion 23 is journaled in a suitable bearing 24 and has communication with a passage 25 exterior of thc tank or receptacle 10 and in which passage it is desired to create a suction, so that when a suction is created in the chamber 22 by the discharge of the liquid by centrifugal force through the arms 19 into the nozzle, the fluid in the chamber 22 and passages 23, 25 through the nozzle. In order to prime the arms 19 to initially fill the pipes or arms 19 with the liquid 18, suitable wings or blades 26'are arranged in the tubular entrance 16 of the support 11 and passage 23.

Thus -it willbe seen that when the arms primed by the aid of the bladesor wings 26, the liquid will be thrown outof the 'arms 19 by centrifugal force and a sti'ong suction will be created in the-chamber 22 and passages 23, 25, when the support 11 is rotated. Y

What is claimed as new is 1. An apparatusof the character described embodying a rotatable .support having a Huid passage therethrough, a nozzle at the outlet .of said passage, there being a liquid passage `through the support'the inlet of which latter rotation of the support, said liquid passage preferably terminatesv short of passage is adjacent the axis of embodying a laterally extended tubular portion terminating adjacent and discharging into the nozzle to create a suction in the uid passage when the support is rotated, and means for ro'tating the support whereby centrifugal force will cause .the liquid to be discharged through the said tubular portion of the liquid passage.

2. An apparatus of the character described embodying a rotatable support having a fluid passage therethrough, a nozzle at the discharge outlet of said passage, there being a liquid passage through the support the in-l let of which latter passage is adjacent the axis of rotation of the support, said liquid passage embodying an extended radial pfortion terminating adjacent and discharging into the said nozzle, the diameter of the outlet of the said radial portion being less than the diameter of the inlet of lthe nozzle, means for rotating the support whereby centrifugal force will vcause the liquid to be discharged through the said radial portion of the liquid passage, and means for initially.
