To all whom t may concern:

Be it known that I, RUDOLPH W. GOEB, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Measuring-Valve Mechanisms, of which the following is a full, clear, and eXact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specilication, in which.

Figure 1 is avertical sectional view through my improved measuring-valve mechanism. Fig. 2 is a sectional view on the line 2 2 of Fig. 1. Fig. 3 is a top plan view; and Fig. 4 is a rear elevational view, partly in section.

This invention relates to a new and useful improvement in measuring-valve mechanisms, the object being to provide means for adjusting the telescoping cylinders forming the measuring-chamber, whereby the cubical contents thereof may be regulated, and also to provide means whereby the valves which coperate with the outer ends of the telescoping sections may be adjusted so as to be seated at the proper time with relation to each other.

With these objects in view the invention consists in the construction, arrangement, and combination of the several parts, all as will be herinafter described and afterward pointed out in the claims.

My improved measuring-valve mechanism is designed particularly for use in connection with the machine for making pulp Stoppers shown in an application liled by me'on Jane uary 19,1905, and seriallynumbered 241,865. The fluid to be measured is pulp-water-that is, water having about two grains of pulp per cubic inch of water-although it is obvious that the present construction is applicable to other kinds of lluid.

In the drawings, 1 indicates the tank .containing the fluid to be measured, and 2 indicates a trough arranged under the tankfor conducting off the fluid after it has been measured and issues from the measuringchamber.

3 indicates a cylinder screwed into the bottom of the tank and having a seat at its upper edge, with which seat coperates a valve 4, having, preferably, a rubber facing 4a for coperating with the valve-seat. Valve 4 is provided with an interiorly-threaded stem 5, which is provided with a longitudinal rib 5a on its side, (see Fig. 2,) which rib coperates with a spider 6, secured in the cylinder 3. By this construction the valve-steinv is slidable longitudinally in the spider, but is prevented from rotation.

7 indicates a hollow cap arranged on the upper end of valve 4 for inclosing the upper threaded end of the operating-rod 8 and eX- cluding the pulp-water therefrom. Rod 8 has threaded engagement with the valve 4. The lower end of rod 8 passes through a sleeve 9, which sleeve carries a valve 10 at ,its upper end, said valve 10 having a facing of rubber 10a coperating with the seat on the lower end of a cylinder 11, said cylinder 11 having a sliding engagement with the cylinder 3, as will berhereinaftcr described. The lower end of sleeve 9 is provided with lateral lianges 9a, forming a head. .Sleeve 9 is also slotted longitudinally, as at 9b, which slots receive and coperate with a cross-pin 12, carried by a rod 13. The lower end of rod 13 has a threaded engagement with a coupling-block 14, which. is pivotallT mounted upon an operating-lever 15. Lever 15 is vibrated, having a definite stroke; but it is 0bvious that instead of the motive power for actuating the rod 13 being in the form of a lever it could be in a different form.

Rod 8, which passes through the sleeve 9, is made hollow at its lower end to receive the rod 13 and its cross-key 12, said cross-key passing through slots .8a in the lower end of the rod 8. The lower end of rod 8 terminates in llanges 8b, on which is seated a spring 16, said spring bearing at its upper end against the flange 9a. The energy of this spring is directed at all times to movethe valves 4 and 10 toward each other-that is, rod 8 carries valve 4 and actuation of the' spring is to move these parts downwardly while sleeve 9 and its valve 10 are pressed upwardly.

In the position of the parts shown in Fig. 1 it will be seen that the cross-key 12 is located in the lower end of slot 9b and in the upper end of slot Su. If lever 15 is moved upwardly, the cross-key will lift the rod 8 and valve 4 so as to admit the fluid in tank 1 into the chamber formed by the cylinders 3 and 11. In this movement the flange 8a IOCi compresses the spring 16 and more firmly seats the valve 10, the cross-key riding up in the slot 9b and not disturbing the position of said valve 10. As lever 15 descends the spring forces the valve 4 downwardly onto its seat until the cross-key reaches the position shown in Fig. 1, in which both valves are seated, the continued downward movement of lever 15 causing the cross-key 12 to engage the sleeve 9 and move valve 10 away from its seat. This unseating of valve 10 enables the contents of the measuring-chamber to be discharged into the trough 2, and also the flange 9a compresses the s ring 16 and causes the valve 4 to more firm y seat itself while the valve 10 is open. This operation of the valves in being alternately seated and unseated enables the fluid in tank 1 to fill the chamber at each elevation of valve 4, and the contents in the chamber are then discharged when valve 10 is open, valve 4 being seated just previous to the opening of valve 10 and valve 10 likewise being seated just previous to the opening of valve 4.

In order to regulate the cubical contents of the measuring-chamber, the cylinders 3 and 11 have telescopic engagement with each other, the cylinder 3, as before described, being threaded into the lower end of tank 1. Cylinder 11, as shown in Figs. 3 and 4, is supported by brackets 17, which brackets extend laterally through slots in the side walls of the trough 2. These brackets have threaded openings in their ends, through which pass the threaded portions of rods 18. These rods are provided with knurled handwheels on their lower ends. Rods 18 pass through perforated lugs or ears 20, secured to the bottom of trough 2, in which said rods are free to turn, collars being pinned on the rod to prevent longitudinal movement thereof, but permitting free rotation of the rod.

In order to adjust the cylinders with respect to each other, the rods 18 are rotated and by reason of the threaded engagement with the bracket 17 will effect a vertical movement of cylinder 11, and thus increase or reduce the cubical capacity of the measuring-chamber. The adjustment of the cylinder 11 will of course change the relation of the valves to the cylinders, and in order to reestablish the proper relation between the valves and their seats I first loosen a jam-nut 14, which locks the rod 13 in the coupling 14, and then rotate the rod 8 and sleeve 9, which effects a changed relation between the valves. Thus if the cylinder 11 was moved up a short distance to reduce the cubical capacity of the measuring-chamber it will be obvious that when the lever 15 is in its central position the valve 10 will be held ofi' of its seat. By rotating the rod 13 in its coupling 14-say to the right-the cross-pin 12 will be elevated, permitting the sleeve 9 and its valve 10 to be raised upwardly by the spring 16. The same motion causes the rod 8 through its threaded engagement with the valve 4 to maintain the established relation between said valve 4 and the rod 13, the threads on rods 8 and 13 having the same pitch. The threaded connection between rod 8 and valve 4 is not for the purpose of adjusting the position of said valve, because the seat with which it coperates is stationary, said threaded connection being used only for compensating purposes.

Should the cylinder 11 be moved downwardly to increase the cubical capacity of the measuring-chamber, it is obvious that the reverse of the operation above described will be necessary. The operator can determine the seating positions of the valves by observing the position of the key 12 in the slots 8a and 9b.

I am aware that minor changes in the construction, arrangement, and combination of the several parts of my device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.
