(ci. 13d- 145) 6 Claims.

The invention relates to a timing device for well intermitters so as to control the admission o! pressure uid lby which the intermittent ilo of the well is accomplished.

T-he present invention relates generally to that combination ci structure shown' in my prior copending application'Serial No. 337,113 iiled May 25, 1940, now. Patent No. 2,339,487, granted January 18, 1944, for a Time and volume control for sas intermitters:

It is one of the objects of the invention to provide a particular Iormot timing-device wherein the -timing isvaried by the removal and insertion of screws or other removable members so as to control the movement oi' a valve lever.

Another'object of the invention is-to provide an arrangement wherein pressure leaksvconstant- 1ythrough the device and is eilective to open the control valvewhen such leakingpressure is conlined and permitted to build up sufficiently to open the valve.

v Another object of the invention is to provide' z of the vtiming device. An entry port n Linto the chamber Il admits pressure fluid so as to dea. suitable reducer valve l1 and the reduced presa combination 'timing and valve mechanism for gas intermitters'.`

Still another object 'of the invention is to provide a special timing disc having removable contact members'. l

Still `another object of the invention is to provide a special lform of adjustable valve lever.

Other and further objects of the invention will be more readily apparent when the following description is considered in connection with the accompanying drawing wherein:

andthe operating parts;

Fig. 2 is a top plan view looking down on the timing unit:

is thus closed, the pressure will build up'in the valve to openon the other hand, urne timing Fig. 3 is a side elevation oi the device of Fig. 2; I

Fig- 4 is a section taken on the line 4-4 of Fig. 3 and illustrates an arrangement oi the timing valve.

' Fig. l'illustrates the general setup and shows 1 the same construction as is illustrated in the lett hand side ofv Fig. 5 or my'copendlns' application. 'Ihe pressure duid from a suitable source ilows through a pipe line 2 through the power valve l l and the pipe' 4' whence it 4iiows yinto the well. This power valve is of a.y particular construction including the valve member 2 which is disposed ina housing i and isoperated by'a stem 1. This 'is anjupwardly closingvalve normally held in closed position bya 'spring' I 4ancla'ctuatecl by a diaphragm 0. y ,diaphragm 'operates in a chamber ll formed by the danse lland thc-body sure hows through the pipe I8 into the timing valve housing il. The details of -this timing valve construction I9 are best seen in Fig. 4. The pressure enters a chamber 20 in the housing I! from the pipe I8 and flows from this chamber into a. choke nipple having an opening 2l therein. This opening is controlled by an oriilc'e 22 which governs the amount of now from the pipe I8.'

This'pressure fluid will nally ilow thru the opening 2l into the chamber 2l and escape from an outlet therein under normal conditions. y

, A timing valve 21 is mounted on the pivot shaft 22 inthe chamber 2l and the spring 2s tends to normally-'hold this valve against the end 'ot the choke nipple, as seen in Fig. 4, to prevent any-V escape of pressure fluid into the chamber 2l and to close the passage 2|. When this timing valve nipple passage 2l and ilow through the port 2| ,and recess into the passage Il and chamber 22 whence it can tlow thru the outlet 35 to the port I3 to build up a pressure in the chamber Il against the diaphragm 8 which will cause the valve 21 is open the pressure will not build up and j the valve will normally remain in clod position.'

YIn order to control the movement ofthe timins valve 21, a lever 4U is aillxed to the shaft 2l, as seen in Fig. 2. 'I'his lever is of particular construction in'that it includes a triangular head 4l which is suitably aillxed upon the shaft by the shank I2. Mounted on this head for pivoting movement is the lever Il pivoted on the screw Il.

A slot in the arm carries a setting screw 48 by which the lever can be adjusted relative to the This lever has 'an upstanding rib 41 thereon which extends along the lever and is arranged to slidably receive the contact arm Il. This arm is adjustably mounted by the screw 4l and the v slot Il.4 This arm has a contact nnger Il and abeveliscell. D j The lever has a plate portion Il which is shown in zFis'. 'Z-as being substantially iiush with the edge of `the finger lVso that the contact face may and the include auinner edge ot the linger Il platen.

The spring 29 normally urges the valve 21 against the choke and this same spring normally urges the lever 43 in a clockwise direction (Figs. 2 and 4) toward the timing disc or plate 60. This plate is mounted upon a/block or other power mechanism -GI enclosed in a housing 62 by which rotation of the spindle 63 is accomplished. The disc 60 is suitably affixed on the spindle 63. The disc 60 is shown as having a plurality of outstanding legs 64. This construction minimizes material and weight of the disc. In any event the disc carries a plurality of timingv pins 65 arranged in spaced relation proxi-l mate its periphery. These pins are seen in side elevation in Fig. 3 and have a knurled head 66 and an intermediate area which is threaded in an opening in the disc 60, and a contact portion 61 which is arranged to engage the face 52 of the nger 15 l. It will be noted that the leg 68 has had the pin v65 removed therefrom and when this leg approaches the area of the finger 5I, the spring 29 will cause the finger to move inwardly of the disc due to the urging of thespring 29. This movement allows the valve 21 to close and when the next succeeding timing pin engages the bevel face 52 as the disc rotates, the lever will be returned tol the position shown in Fig. 2, overcoming the compression of the spring 29 and causing the timing valve 21 to again open. In other words, by adjusting the position of the finger 5l, the time during which the .timing valve 21 is closed can be controlled. If a long period of time is desired, more than one pin 65 can be removed and by adjustment of the linger 5I any desired proportion of the timing interval can be also adjusted. Thus, by manipulating the number of pins and the position of the linger 5l, any

desired timing can be accomplished. Different pins may be removed to obtain different periodic timing operations.

As pointed out before, when the valve 21 closes, the pressure builds up to open the power valve. It is to be noted that the nger 5l and the plate 53 arrangement is such that it will span the distance between he two pins to prevent its dropping in between them. If all of the pins are in place, the valve 21 will remain open and the power valve will remain closed. The pressure from the source would then continue to leak through the device and escape to the atmosphere When the timing valve 21 closes, however, the mechanism is then placed in operation by opening the power valve.

Broadly, the invention contemplates a ,timing mechanism for well intermitters which can be readily adjusted to accomplish any desired timing interval.
