STOCK REGULATOR Filed Aug. 5, 419:29
w ATTORNEYS laten'ted- .lune 17, `193() PATENT OFFICE WILLIAM I?. FEENEY, OF MANISTEE, MICHIGAN srocK intentaron Application filed August 5, 1929. Serial No. 383,446.
This invention pertains to improvements in regula-tors and more particularly to stock regulators for paper making machines.
In my Patents 1,134,831, granted April 6,
1915; 1,143,523, granted June 15, 1915, and 1,331,057 grantedl February 17, 1920, I have lshown certain types and improvements in stock regulators for paper making machines.
This invention relates to certain improve- 1o ments on these inventions and other improvements not disclosed in any ofthe above patents.
Previously there have been certain disadvantages in stock regulators such as permitting stratification of the pulp whereby settling takes place allowing a variation in density of the stock fed to the paper making machine. Also there has Vbeen a certain lag in the reaction of the control mechanism toy changes in volume or characteristics of the feed stock.
One of the primary objects of my invention is to overcome the disadvantages stated above. V Other objects and advantages of my invention will become apparent from the follow-` ing specification and drawings in which;
Figure 1 is a perspective view of my stock regulating apparatus, and
Figure 2 is a detailed view of the adjust- .30 able float portion taken after 2 2 of Figure 1.
Referring more particularly to the drawings in which like reference characters denote like parts, my device consists of a stock regulator 1 which may be a box of wood or metal or other suitable substance. This regulator 1 is dividedinto sections 2, 3, and 4 by means of the partitions 2 and 3. The stock is admitted to the section 2 through the inlet pipe 5. There is an outlet line 6 from the overflow section 3 which returns the stock to the supply. The outlet 7 from the section 4 directs the stock to the paper making machine.
j Y The regulating mechanism consists of a oat 8 which may be spherical or any other shape. The spherical shape appears to be most suitable for this purpose. The float is connected by means of the adjustable rod 9A to the arm 10 which pivots at 11 on the bearings 11. This arm 10'is preferably made of aluminum or other light alloy so as to render the iioat as sensitive to variations in liquid level or density as possible. `The gate 12 is also connected to the arm 10. A weight 13 adjustably movable on the arm 14 may be used to counterbalance the weight of the arm 10 the gate 12, and the float 8. A hand wheel 15 is connected to the threaded rod 19 permitting the float to be adjusted vertically. Thus the Hoat may be regulated in such Va manner as to permit the flow of the amount of the stock, desired at the paper machine.
There is an opening 16 between the sections 2 and 3 of the regulator boX. Atthe bottom of this opening there is a lip 17. The gate 12 65 moves in this opening and may rest on the lip 17 in such a manner as to not allow any stock to flow from section 2vto section 3 under the gate 12. vAt the sides of the opening 16 there are placed the flanges or projections 18 and 19. These have an edge 20 which is curved to the arc of movement of the gate 12. Thus these flanges 18 and 19 also act as closure mediums to substantially stop any stock from iiowing around the sides Vof the gate 12 into 75 the overflow section 3, when the gate 12 rests on the lip V17. On the other side of the gate 12 and also fitting snugly against itwithout hindering itsmotion, thereis the trough or apron 21, the forward part of which rests on the supporting bar 22. I have shown this trough as being adapted to pivot at the point 23 so that the forward edge may be lifted upon a vertical position. This operation will be described more in detail later.
In section 21r have shown lillets 24 in the corners where the sides of the regulator boxV connect with the partition 2. These llets eliminate dead corners where there would be no circulation of the stock and thus a tendency for the stock to' settle or separate.
The operation of my device is a follows:
`Stock is 'pumped into the section 2 through Vthe pipe 5. The stock ills the section 2 and Hows over the gate 12 onto the apron 21 and into the section 4. The float 8 may be adjusted to such a position that when the feed stock entering through the pipe 5 is sufficient to take care of the amount required by the paper making machine, the gate 12 will 100 rest on the lip 17. Therefore, should the supply of stocks entering section 2 increase over that required by the machine, the float 8 will be lifted. This in turn lifts the gate 12 and permits an opening between the lower portion of the gate 12 and the lip 17. It is seen that the forward portion of the trough or apron 21 is above the lip 17 so that when the stock passes over the lip 17 it drops into the chamber 3 and is returned to the stock pump or supply through the pipe 6. Stock, of course, may still pass over the upper portion of the gate 12 on to the apron 21 into the section l to the paper making machine. Due to the opening between the gate 12 and the lip 17 the level of stock in chamber 2 is lowered and thus the float 8 again drops and closes the flow into the section 3. The flow of stock may be such that there is continually an opening from section 2 into the section 3 and yet stock flowing over the gate continuously on to the apron 21. Such an operation would be brought about if the supply coming in through the pipe 5 was consistently greater than the amount required for the paper making machine flowing out through the pipe 7. In such a case there would be a certain amount continuously recycled from the section 3. By adjusting the float 8 to the proper position it is possible to obtain an even flow of any desired amount of stock to the paper making machine. If it is desired to eliminate the paper making machine completely from the circuit, either permanently or temporarily, the trough of apron 21 may be lifted, pivoting about the rod 23. In this way any stock which flows either over or under the gate 12 drops into the overflow chamber 3 from which it would be returned to the supply source.
My device is also sensitive to changes in density of the stock. If the stock becomes thick the float will tend to rest higher on the stock and thus recycle a. certain amount of the heavy stock. In this way the amount of solids to the paper making machine may be controlled.
It can therefore be seen that in my regulator stratification in the supply chamber 2 has been eliminated, and that there is always circulation through this chamber. Thus there is no variation in the density of the stock which is permitted to flow through the paper making machine. Also I have a structure in which the bearings are positioned at such a point as to not be affected by water or stock. In this way I am able to use ball bearings and thus obtain a very sensitive control.
1While I have disclosed only a specific form of my invention and in connection with a speciflc use, it is obvious that there may be changes and improvements which might be made by one skilled in the art without departing from the spirit of the invention. I
therefore, wish to be limited only by the appended claims.
I claim:
