NITED STATES PATENT OFFICE.
HEINRICH SOHAAF, OF NEUSTADT ON-THE-HARDT, GERMANY, ASSIGNOR TO ROBERT DIETRICH, OF MERSEBURG-ON-THE-SAALE, GERMANY.
PAPER-PU LP-DISCHARGE VALVE.
SPECIFICATION forming part of Letters Patent No. 691,975, dated January 28, 1902. Application filed March 15, 1900. Serial No. 8,717. (No model.)
To all whmn it may concern: i
Be it known that I, HEINRICH SOHAAF, a subject of the German Emperor, and a resident of Neustadt-on-the-I-Iardt, in the Palatinate of the Rhine, in the German Empire, have invented certain new and useful Improvemen ts in Paper-Pulp-Discharge Valves, of which the following is a specification.
This invention relates to improvements in paper-pulp-discharging valves.
The nature and object of the invention will be fully understood from the following general description and the annexed drawings, and will be subsequently pointed out in the claims.
Figure 1 is alongitudinal sectional view of Fig. 2 is a sectional View of the valve-spindle, taken on the line A B of Fig. 1, showing the valve-cone from below. Fig. 3 is a longitudinal sectional view of a modification of my improved valve when open. Fig. 4 is a sectional view of the valvecone, taken on the line C D of Fig. 3 looking from below. Fig. 5 is a detail sectional view of the valve-cone when closed. Fig. 6 is a sectional view of the cocks of the waterpressure conduits, taken on the line E F of Heretofore paper manufacturers have been much hindered and annoyed by the pulp which they were manipulating sticking in the conduits through which it was passed and choking them so as to retard the work. 'My present invention has been devised to obviate this difficulty.
Referring to the drawings hereto annexed,
which are hereby made a part of this specification, a designates the body of the valve, which is of the curved form illustrated. This is to be secured to the bottom of the paperpulp engine by means of screws or in any other common and well-known way that will be sufficiently strong. Pulp from the engine passes through the valve in the common and well-known way. The hollow valve-cone c and the tubular valve-spindle d are made integral with each other. This valve-spindle 61 passes through the hub e of the body aof the valve.
A piston (designated by f) is rigidly mounted on the lower end of the spindle d.
This
a series of holes ZZ.
piston reciprocates upward and downward in the chamber g. The chamber g is closed by the cover 72.. The tubular valve-spindle d communicates with the pipe 7;. This pipe 1' is fitted with a stop-cock k. The bottom of the valve-cone c is perforated all around with The valve-spindle is also in like manner perforated with holes m at'the line A B. i
In the wall of the chamber g is an orifice at. In this may be inserted a cock, by opening which the pressure in said chamber may be relieved, if it should be found that such relief is expedient.
When the stop-cock 7c is opened, water from an adequate supply under pressure runs through the pipe 2', under the pistonfithrough the hollow spindle, and into the cone 0. This action raises the piston f and with it the spindle d and the cone 0, and atthe same time the water escapes in jets from the holes land on. These jets of water prevent the pulp from adhering to thecone c, the spindle d, or hub e while being discharged through the valve and greatly assist insuch discharge. When the pulp has been discharged and the stop-cock 7c has been closed, the surplus wa ter which had run into the spindle (Z and the cone 0 continues to escape from the holes Z and m until it is exhausted. Then the cone 0, the spindle d, and the pistonf automatically sink down to their former positions.
- In the example of my invention illustrated in Fig. 3 the supply of water for the jet-holes is separate from that which operates the piston. In this case the valve-cone c is loosely mounted on the spindle d. To the top of the spindle is fitted the cover it, perforated all around with a series of holes 0. The spindle 01 extends through a tight stufiing-box p in the cover h of the chamber g and is furnished with a hose connection at its lower end. Water under pressure is conveyed to the tubular spindle d from the conduit 1" through the short pipe .9 and the hose If. Conduits u, u, and n convey this same water under pressure to the chamber g to actuate the piston f. The stopcocks o and to open and shut the conduits s and a and are operated together by the lever 00 and draw-bar y. When the stop-cocks 'v and w are closed, the surplus water in the conduit it runs off through ahollow in the stopcock 1). It is evident that compressed air may be used instead of water for actuating the pistonfin the chamber g.
In Fig. 3 the valve is illustrated in open position, with the valve-cone c resting on the ring g, which surrounds and is supported by the valve-spindle d; but if the stop-cocks v and 10 be reversed the water feeding the jetholes 1 m 0 in the cone 0 and the spindle 61 will be shut off. At the same time water passing through the pipe a into the chamber 9 will force the piston f downward and close the valve, and at the same time the spindle d is moved toward the piston f, the holes 0 are thereby closed to prevent the pulp from getting into them, and the holes m of the spindle passing into the hub e are also closed, and thus by changing the stop-cocks o and w the valve may be opened and closed at pleasure.
, Otherwise than hereinbefore described this valve is to be used in connection with an ordinary paper-pulp engine in the common and well-known Way.
What I claim as my invention, and desire to secure by Letters Patent, is
1. The combination of a curved valve-body substantially as specified, with a hollow perforated valve-cone, and a tubular perforated Valve-spindle, all arranged, and substantially as and for the purpose set forth.
2. In a paper-pulp-discharging valve, the combination with a curved valve-body substantially as specified, a pressure-chamber in said body, and a piston reciprocating in said chamber, of a hollow perforated valve-cone, a tubular perforated valve-spindle connected thereto and connected with said piston, and working therewith, and means for supplying the same with water under pressure, all substantially as and for the purpose set forth.
3. In a paper-pulp-discharging valve, the combination with a curved valve-body substantially as specified, a pressure-chamber in "said body, and a piston reciprocating in said chamber, of a tubular valve-spindle passing through said piston, and the bottom of said chamber, a ring upon said spindle, a hollow perforated valve-cone loosely mounted on said spindle, and resting on said ring, Waterconduits to supply said valve with water under pressure, and stop-cocks in said conduit to regulate and control the flow of said water, all substantially as and for the purpose set forth.
In witness whereof I have hereunto set my hand in presence of two witnesses.
HEINRICH SCHAAF.
