RUDOLPH 'oonnanna or nainv PENNSYLVANIA.

l REGULATOR.

To all whom it may concern:

Be it known that I, RUDoLPHCoNnA-DER, a-citizen ot the United Sta-tes, residing at Erie, in the county foil Erie andState of Pennsylvania, have inventedneiv and usey'ful Improvements in Regulators, ot which the following is a specification.

This invention relates to regulators and consists 1n certain improvements inthe construction thereof as will be hereinafter fully described and pointed outlin the claims.

More particularly the invention relates to that type of regulator yWhich is actuated by a pressure' device, and the controlling valve of the regulator is usually so connected With either' a motor or compressor so thatthe action upon the controlling 4valve controls' the pressure. With regulators of this type,

it isV desirable for different purposesto have `diner-ent actions of the controlling valve under the influence of changes of pressure on the pressure device. That is, tor some 1mi-poses, it is desirable to have a pressure device which moves the valve gradually with an increase of pressure on the pressure device. While for other purposes, itis desirable to have Vthe controlling device move from one extreme to the other upon certain changes of pressure.

@ne of the objects of this invention is to arrangeI the pressure device so th'atit fmayv be adjusted to operate as desired in this r`espect.k n

The invention also involvesy an ment' in the controlling' valve. y

The invention isr illustrated in the accom-y improvepanying dravvings as follovv's: i

Figure 1 shoivs a plan vievv, partly in section on the line 1-#1 in Fig. 2. isa section on the line 2 2 in Fig. 1. FigQB 1sl a section on the line in Fig. l.; 1 marks thebo'dy' of the valve,`2` thedia'f phragm. The diaphragm isr double in form so that there is an outlet, and inlet tremit, both top andbott'omf. yFluid passes through the valve in either direction by the ope'nings 1u and 1b. y

A bushing 3' is secured in one Wall ofthe diaphragm, and extends through the opposite Wall. It has radial openings 4 entending through itv between the Walls of the dia` phragin, and the Walls 2a connecting'the diaphragms are oi' suiiicient distancetrom the bushing 3 totorin a pz'issaa'el'2b sothat the fluid can' enter or discharge" from cihe bushf ing in au' directions. The valve 5 isor the Specification of Letterslatent.

. balanced. n The valve body is provided with a cover 7,.

rotative type, and is arranged in the bushing, and has radial openings 6 which are brought into' and out ot register With the openings e to open and close the valve. The

valve' is opened top and bottom so that the fluid passing the valve, enters or discharges both directions ofthe valve. 1n this Way,

the valve is given large capacity, and is andthis cover is secured to the body by the screiv 8. A; gland 9 is arranged in the cover 7, and the valve stem 10 extends through this gland. 'The lower end of the valve is squared at 10a, and extends into a squared socket 'LL in thetop ot the valve. This is a comparatively loose iit so' that the valve can readily iind its position Without binding ot the parts. The upper end of the stem has the squared end 11 on which a crank 12is arranged. Vrlhe crank has the throated end 13.

The pressure device is as iolloivs: A cylinder 14 is secured on the bracket l5v extending from the 'cover 7, and is securedA thereon by' means ot' the screyvsl. Fluid is pumped to theV cylinder through a pipe 17, and.v of course, leads from some supply which itis desired to control, ordinarily a receiver. A piston 1S is arranged in the cylinder, and this operates upon the pitman 19, the inner end of which' is arranged in a socket in the piston. rlhe pitman has the throated end 20, and the links 21 are arrangedeach side oit the throated end and connected there With by thepin 22. The links 21 are also connected to an ear 23' extending from the cylinder bymeans of a pin 24; The pitman' engages a lever 25 and is provided With a roll `192L` between the arms of the throatedk between the -ears v26 on thev cylinder vby means of a pin 27. It has the throated end 28 between the arms of which arranged a` trunnion 29. A link 30 secured between `the arms fo'rrns the throatedfend 13 of the;

crank by means oi a pin 31. The opposite end ot the link 30 is screwthreaded andy extends through the trunnion 29 and secured tothe trunnion by' means of the nuts 32, on each side ofthe trunnion. By' means f these, the link am be adjusted to give the valve any desired initial position. The eX- tension 83 is arranged on the lever25, and iS connected with a head 34 by means of a pin 36, the head 34 having the arms 35 extending each side of the extension 33. AV pin 37 is screwed into the head and extends through the screw 38. The screw 3S is arranged in a stud or post 39 extending from the cylinder 14. rFhe end ottherod 37 is screw thread-,' ed and a nut 40 is screwed onto the rod against the screwSS, and by means of this Y it nut, the initial position of the rod may be adjusted, and the adjustment locked by the jam nut 4l. A spring-,42 is tensioned between the'head 84, andl the screw 38. Any

' Y desired tension may be given to thisspring by operating'the screw 38. It'will be observed that moves outwardly as the'piston moves under' the influence of the fluid inV the cylinder as Ythe pitman 19 y the outer end of the pitman operatingV on .tlielever and cam 25Va is controlled by the links 2l, and swung to a circular path with f the pin 24 as a center. In the beginning ofl this movement, the path of the outer end of the pitman is about in line with the pitman, and the end `of the pitman .is nearest Ythe pivot formed by the pin '27 of thelever 25. YAs the pitman Vmoves outwardly, however, its path of movement is deflected more and more vfrom a direction in line with that of the piston; and'V consequently, there is a greater ratio ofV movementl ofthe pitman along the lever 25 with va given'endwise movement of the pitman as the pitman y reaches its outward positions.

In the norn mal use of the'regulator but a small part of the possible travel of the piston is neces-. sary. Consequently, the pitman may be ad-k justed soras to. havean initial position as ,shown4 in Fig. `1 in ywhich case the j ratioV of increase in leverage by reason of f thev moving of the end of the pitman awayv from the pivot of the Vlever 25 is but slight. It 1t is desired to have this leverage increase r very rapidly'so that, for instance, if itis Vdesired to have .the valve completely close when the pressure on the piston reaches a point that will start it, this may be accomplished by adjusting the rod 37 by means ofthe screw`4l to a position which will bring thel initial position vo-the'end of ythe pitman engaging the lever 25 outwardly from that shownin Fig. 1 so that-the continued movement of the pitman will'be morev abruptly deflected from the lineof movement of the piston so that vwith a given movement of the piston, the movement of the end of the pitman relatively to the pivot 27 is very rapid,`and consequently, the leverage will increase more rapidly than the strengthof the spring by reason of' its compression. Inthis way, any variation along ,this `line; may beisecuredzthat may be desired simply by adjusting the initial position of the end of the pitman. After the leverand pitman are adjusted to the position desired for them, the link 30 may be adjusted so as to give the proper initial .position to the valve, and the screw 38 may be adjusted to adjust theV tension of the spring 42. Of

course where the screw 38`is so adjusted,v

the nut 40 should be adjustedfto compensate for thediiference in position oic the screw.rk
