HUTCH-VALVE-OPERATING MECHANISM.

Specification of Letters Patent.

Patented Oct. 25, 1921.

Application filed March 8,1919. Serial No. 281,418.

To all whom it may concern.

Be it known that we, AXEL G. J. RAPP and LAURENCE M. EwELL, citizens of the United States, residing, respectively, at Chicago, in the county of Cook and State of Illinois, and at East Liberty, Pittsburgh, 1n the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in Hutch-Valve-Operating Mechanism, of which the following is a specification.

Our invention relates to a hutch-valve operating mechanism for use in concentrating jigs and the like, and has for one object to provide an automatically operated and timed mechanism for periodically opening and closing the valve in the bottom of the hutch, so as to provide for the escape of sludge while preventing any unnecessary loss of water.

It is illustrated more or less diagrammatically in the accompanying drawings wherein- Figure 1 is an end elevation of a jig partly in section with the valve mechanism installed;

Fig. 2 is a plan view of the valve operating mechanism;

Fig. 3 is a detailed section along the lines 3-3 of Fig. 2.

Fig. 4 is a detail section along the lines 4=4 of Fig. 2.

Like parts are indicated by like characters in all the figures.

A is a jig having at its bottom a valve A carried on the valve rod A which has near its upper end the lifter stop, A and at its top the handle A.

B is a valve lifter arm rotatably mounted on rocker shaft D and having at its upper end the portion B provided With the bearing surface B and at its other end the portion B carrying in its end the bearing B*.

C is a lifting dog slotted at C to admit the portion B of the lifter arm B upon which it is mounted, and provided with the hooked portion C and the upper extension C which has on its under side the bearingsurface or buffer C D is a rocker shaft upon which is keyed the arm D It has keyed to it the levers D which have rotatably mounted between them at their ends the pawl D D is a ratchet wheel rotatably mounted on the rocker shaft D, notched as at D and having one substantially deeper notch D.

E is a shaft upon which is mounted a gear wheel E and the crank E to the pin E of which is connected one end of the connecting rod E5 The other end of this connecting rod is connected to the rocker arm D F is a shaft carrying at its end the pinion F which is in mesh with the gear Wheel E The shaft F has mounted upon it the sprocket wheel F in mesh with the driving chain F which is driven by sprocket wheel G mounted on driving shaft G.

H 18 a tripper rod secured to the frame of the jig, bent at its upper end to form the hook H having at its lower point the operating surface H adapted to strike against and depress the upper projection C of the lifting dog 0 I I is a ratchet dog supported at I on the hutch base and having the flattened end I adapted to ride upon and engage the teeth of the ratchet D.

J is a counter weight adapted to fit upon and slide along the short portion I of the ratchet dog I,

The use and operation of our invention are as follows:

By means of suitable gearing a rocking motion is imparted to the rocker shaft D upon which are mounted two lever arms D These levers have between them a ratchet wheel D and the valve lifting arm B, and carry at their ends a pawl D As the rocker arms are rocked down, the pawl engages one of the notches in the ratchet, rotating the ratchet wheel. As they are rocked up, the pawl rides over these notches. Once in every revolution of the ratchet wheel the pawl will enter the deep notch. Vhen it does so it penetrates sufficiently within the ratchet wheel to engage the end B of the valve lifter arm, depressing it and raising its other end thereby raising the lifting dog C which engages the lifter stop on the valve rod A and thus raises the rod. \Vhen the rod has been raised sufiiciently the upper projection of the lifting dog strikes the tripper rod, and is depressed and pushed out of engagement with the lifter stop, so that the valve rod is dropped, and the valve is thereby closed.

If more than one deep notch is used, and a plurality may be desirable to give a more frequent action of the valve, then each time that a deep notch is engaged by the lever,

the valve will be opened.

We claim 1. In a valve operating mechanism, the combination of a driving part, a power transmitting part, means for intermittently connecting them, a valve, a connection between it and said power transmitting part, and means for terminating said connection after a predetermined travel of said valve.

2. In a valve operating mechanism, the combination of a driving part, a power transmitting part, means for intermittently connecting them, a valve, a connection between it and said power transmitting part, comprising a dog adapted to engage said valve, and means for terminating said connection after a predetermined travel of said valve, comprising a dog tripping element.

3. In a valve operating mechanism for hutches and the like, the combination of a driving part, a power transmitting part, means for intermittently connecting them, a lifting valve, and means for intermittently connecting the power transmitting part with the valve.

4. In a valve operating mechanism for hutches and the like, the combmation of a driving part, a power transmitting part,

'means for intermittentl connectin them a y a: a

lifting valve, means for intermittently connecting the power transmitting part with the valve and means for intermittently disengagin them.

5. n a valve operating mechanism for hutches and the like, the combination of a driving part, a power transmitting part, means for connecting them, comprising a ratchet wheel and pawl, a lifting valve and means for intermittently connecting the power transmitting part with it.

6. In a valve operating mechanism for hutches and the like, the combination of a driving part, a power transmitting part, means for connecting them, comprising a ratchet wheel and pawl, a lifting valve and means for intermittently connecting the power transmitting part with it and means for intermittently disengaging the power transmitting part from it. I

7. In a valve operating mechanism for hutches and the like, the combination of a driving part, a power transmitting part, means for intermittently connecting them, comprising a ratchet wheel with one or more notches substantially deeper than the others and a pawl, a lifting valve and means for connecting the transmitting part to the valve when the notches.

8. In a valve operating mechanism for hutches and the like, the combination of a driving part, a power transmitting part, means for connecting them, comprising a ratchet wheel withone or more notches substantially deeper than the others and a pawl, a lifting valve and means for intermittently connecting the power transmitting part with it adapted to be engaged by the pawl when it penetrates said deep notches.

9. In a valve operating mechanism for hutches and the like, the combination of a driving part, a power transmitting part, means for intermittently connecting them, a lifting valve and means for connecting the power transmitting part with the valve, comprising a lifter dog and stop.
