Specification of Letters Patent Patented Oct. 27, 1908.
Application filed May 24, 1307 Serial. No. 376,478.
To all ill/mm it imp concern:
Be it known that l, Cmus'rnuv .llAvns'mm',
as the lion ting suction chau'lbcr adapts itself to the various water levels which a stationof Vi ilmcrsdorf, a subject of the King of ary chamber is not capable of and it has the Pro L121, and whose post-other: address No 15;.) Bel-linorstrasse, \Vihnersdorf, near Berlin, Prussia, German Empire have invented new and useful. Improvements in Devices for lflxhausiziug Air from Siphons of Sluices and the Like, of which the following is a specification.
The invention. relates [0 means for removing the air frcm eiphons such as are used for this purpose, the water contained therein 3 being let oil into the lower level of the sluice so as to obtain in the chamber or in the bell the necessary space for the air to be removed from the siphon. These stationary suction chambers however have the disinivanta ithat a water column. must remain between the air in the suction chamber and the atnn'lspnerc of a height equal to the dillcrence h pressure between the pressure in lhe chamber and the ahnospheric pressure. It. is therefore necessary to arrange the stationary suction chamber at as high a level as possible. lllovable slntion bells ln'n'c then forc already been employed for exhausting the air from siplibns iii-slums or llKiliH. lo obtain the space ncccs ary for the air rcmoved from the siphon. The mechanical means however employed for raising or lift ing such movable bells for the purpose aforesaid required power cspm-ially if the raising is to be effected quickly, the lower incrcas' ing according to the incl-ens 1g attenuation of the air.
According to the n-esent invention float ing suction chamber is cn'iployed for enhausting the air from siphous of slunrm, reservoirs and the like, 2'. c. a suction chamber which is provided with one or more oul let or discharge pipes and is connected up to the suction conduit 01' the siphon and the clnuulmr not being slatlonarv but rigidly connected with a floating chamber or casing so ihat it li0ats freely in the water. being nnlded vertically in a similar manner to :i gas collecting bcll. This floating suction chamber hasilibe adwoita rc that it enables siphon locks to' be used for siluiccswifh considerably fluctuating falls such sea sluiccs,
further advantage as compared with the mechanically raised suction bells, that it re quires no special external power for rais ing it.
The accompanying drawings illustrate two modes of carrying out the invention.
Fi ulrcs 1 and SllOW in section and in two different positions a simple form of suetion chamber which is lillcd from the lower portion or level of the sluice by means of only one discharge pipe. Fig. 3 shows in section another forum having two discharge or flow ell" pipes which nnty be closed if the motion chamber to be filled from the upper part of the sluice.
In carrying out the invention according to one mode as illuslraleil by Figs. 1 and 2,
, the suction chamber, 4/, is rigidly connected with a closed floating chamber or casing, b,
i by moons of a framcivorlo r, or the like and connected with deep water by means of one discharge pipe, j', although more than one may be used. Guide rails, c, are ar ranged. on the supporting or side walls, is, the chamber, in and the floatingchamber or casing, a, being guided up and down thereon by means of rollera, 1 in a similar manner to a gas collecting bell. (Z, is the suction pipe leading to the sluice siphons. The vertical part of the pipe, (I, works in an air tight stalling box, 0', leading to the suction chamber, a.
In the position. shown in Fi 2- the tank a is filled, the pipe. is closed by means of a known suitable distributing device such as a. three-way cock or the like (not shown in. the drawings) against the atmosphere. Vv'ilbin the said pipe "I in the said position of the chamber a is a partial vacuum. NVithin llie. siphon is atmospheric pressure, so llml \i lTPn by means of the said distributing device lhc pipe 4/ is opened for connecting the chamber a with the siphon, air passes from 'lhc latter into the said chamber (1', thereby displacing the water from the chamber through pipe f. The chamber a and the floating chamber 7) are raised corresponding with such displacement of Water until the clmmbor is completely, emptied and reaches its highest position, as shown in Fig. 1. A Watcr column stands in the discharge pipe f balancing the partial vacuum in the chamber a.
W'ithin the siphon the overflow of air into the chamber (1 effects a diminution of pres- 5 sure of the remaining air. In consequence the atmospheric pressure lifts the water in both legs of the siphon. As soon as the water in the le connectcd with the upper level or pond o? the sluice has reached the ridge of the siphon and flows over into the other leg connected with the under level or pond of the sluice, the air yet contained in the siphon is taken away and the siphon is completely filled with running water. In conse uence the air in the chamber a is sucke off through the pipe at and water enters from the under sluice level through the discharge-pipe f and fills the chamber a. Now the chamber a together with the floatin chamber 6 sinks again. For the initial fllfing of the chamber a, a suitable air pump can be used for sucking off air from the pipe cl and the chamber a. After the chamber a has been filled and a partial vacuum has been produced in said pipe d, the latter is closed against the atmos here 1n the manner described. But prefera ly an arrangement is provided for making the initial filling from the u per level of the sluice, as shown in Fig. 3 o? the drawings.
In the form of construction shown in Fig. 3 two dischar e pipes, f, are provided which may be'close by means of valves, h,.if the tank or chamber, a, is intended to be filled, from the upper level by means of a special filling connectiorifll, the chamber, a, being connected in this case with the upper part of the ,sluice by means of a flexible conduit such as a hose j, or the like-provided with a corresponding connecting piece.
For the purpose of initial filliii and prodncing a partial vacuum within t e pipe 01, the valves h are closed and the valve 2 of the hose j opened. Before the chamber a has against the atmosphere. Then the, valve 71 isv c osed and the valves k are opened. Now
the apparatus is in the condition as shown in Fig. 2 and its function is as referred to.
