CHRISTOF HEERLEIN, 0F NUREMBERG, GERMANY, ASSIGNQR TO PFISTER & LANG- HANSS AKT.GES., OF NUREMBERG, GERMANY.
HYDRAULIC RAM.
. Application filed July 1, 1925. Serial No. 40,792.
To all 'whom t may concern:
Be it known that I, Crrnis'roi1 HEERLEIN, engineer, a citizen of the German Republic, residing at Nuremberg, Bavaria, Germany, have invented certain new and useful Improvements in Hydraulic Rams, of which the following is a specification.
The present invention relates to a hydraulic ram, in which the outflow of the driving water is downwardly directed.' Hydraulic rams are very well known in many different constructions. Normally these rams are constructedin such a manner that the exhaust of the driving water is effected upwardly or sidewardly. But there are modifications too, in which the exhaust of the waterV is downwardly directed. In view of utilizing the height of the fall the last named construction is especially favourable. On the other hand a special control of the percussion valve was necessary in constructions of this kind, so that the other advantages became useless thereby.
Now, the present. invention consists in employing a percussion valve of known structure instead of a downwardly Vdirected andcontrolled percussion valve; in this case the percussion valve is compensated and acts perfectly automatically without any controlling or governing device. As compensating device a yielding elastic ribbon or spring is suitably employed, toward whichthe valve 'abuts In the annexed drawing a practical mode of execution is represented. p
Figure 1 shows the entire arrangement in vertical cross-section.
Figure 2 is a side view, and
Figure 3 shows the air suction nozzle in cross-section.4
The body of the ram principally consists of a curved pipe A, the back end B of which is not horizontal and has the same inclination as the power conduit C. The latter conduit is connected with the curved pipe A vof the ram B by an inserted stop-valve or slide D. The other free end E of the pipe A is downwardly and vertically conducted in a slight curve and carries at its mouthpiece the percussion-valve F. The exit-conduit of the percussion valve is permanently secured in the lower water H, which is led off by means ofthe pipe J. 4
The curved pipe Aris secured on the'base or support K. `The pressure pipe-stud L is vertically arranged, supporting in the well known manner the air-tank M, the pressure- `valve N, thebranch pipe O for the liftlvalvel said springs being arranged on the outside of the pipe. In a like simple manner the spring is connected with its adjustable abutment. y n
The hydraulic ram is started in the well known manner. By balancing the percussion-valve Q by means of an elastic flat spring thevalve acts without any controlv orY steering device. The openings in the percussion valve' may be made of larger cross-section, so that the power water in its passage meets only a weak resistance. The tension lof the flat spring R may be varied within widelimits by altering the point of abutment in a sensitive manner andk the action of the hydraulic ram accordingly.
yThe construction of the flat spring obviates any wear and excludes any disturbing supplementary oscillation.
I claini- A hydraulicram comprising a curved pipe secured at one end to a power conduit and having a pipe stud intermediate its ends; a percussion valve secured at the other end of said pipe; a vertically disposed air tank secured to said pipe stud; a valve in said pipe stud which isfadapted to admit water into the tank; and a double circular spring secured to the outside of saidpipe and being adapted to force said percussion valve in its open position, said spring being adjustably mounted at the pipe connection.
In testimony whereof I have affixed my signature.
CHRISTOF HEERLEIN.
