SPECIFICATION forming part of Letters Patent No. 775,392, dated November 22, 1904.

Application filed January 29, 1902. Serial No. 91,785. (No model.)

T0 all whom, it mfty concern,.-

Be it known that I, RUDOLPH OONRADER, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, haveinvented certain new and useful Improvements in Regulators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to regulators; and it consists in certain improvements in the construction thereof. as will be hereinafter fully described, and pointed out in the claims.

The invention is illustrated in the accompanying drawings, as follows:

Figure l shows a plan view, partly. in seetion, on the line l l in Fig. 2. Fig. 2 shows a section on the line 2 2 in Fig. 1. Fig. 3 shows an end elevation from the right of Figs. l and 2. Fig. 4f is a partial section on the line 4 fl in Figs. l and 2.

A marks the valve-chamber; B, the valve; the valve-stem; C, the cover for the valvechamber, from which project the extension O' and frame O2. The block b/ is secured to the stem The lever G is pivoted on this block. The lever G is provided with a guide g2, in which is fitted the fulcrurn-block g3. The fulcrum-pins g are secured to the block (f3 and extend into a sliding yoke gh The sliding yoke g* is secured in the guide c. A yoke c extends from the frame C2, and an adjustingscrew c2 is arranged in this yoke and operates upon the sliding yoke g4, so as to vary the position of the block g3 on the lever G, and consequently the arm of the lever, so that the stem and valve B are given a greater or smaller' movement relatively to the movement of the outer end of the lever G. The outer endof the lever G is pivoted at g in a yoke IQ Extending from the lower end of the yoke I is the stem 3. This stem rests upon the piston R. The piston R operates in the cylinder L. The cylinder L is provided with the shoulder Z2 and is placed in an opening in the extension C@ A cap L is screwed onto the end of the cylinder, and this, with the shoulder Z2, locks the cylinder in the extension C. Air or fluid under pressure is admitted to the cylinder L from the chamber M. It enters a chamber 7u* in the piston, passes through a minute opening f to the bottom of the cylinder, and, exerting pressure here on the bottom of the piston, the piston is made to rise and operate the regulating-valve B. Oil is preferably placed in the chamber z'", and the opening 1 forms a dash-pot, the opening being small enough for this purpose. A minute opening' r opens into the passage J, and a lateral opening extends from the passage t' to the surface of the piston, thus lubricating the piston.

Arranged at the side of the yoke I are the arms I3. The springs I* connect these arms with the lu'gs L", extending' from the cylinder L. These springs form a counter-pressure device for the motor formed by the piston K.

A supply-opening f/n/ leads from the cylinder N into the chamber IWI, anda minute vent m leads from the chamber M to the atmosphere. Arranged in the opening m is the valve P, with the needle end p. The valve is provided with a cap p at its end and is secured to a plunger O by means of a Hangenut o, arranged in a cavity o in the plunger O. The plunger O operates in the cylinder N. The receiver-that is, any receptacle in which the Huid-pressure is regulated--connection N' leads into the cylinder N between the end of the plunger and the supply-opening m. Extending outwardly from the plunger is a stem O, which engages the lever Q. The mechanism for securing the spring to the lever comprises the adjusting-bolt r and thumbscrews lr', by which the bolt may be locked in position. Extending' from the lever Q is an arm Q', on which is adjustably mounted the weight Q2. A screw q is provided for locking the weight in any position. An arm q extends from the upper end of the lever Q. A set-screw Q is arranged in this arm in position to limit the swinging of the lever Q and the outward movement of the plunger O. A jam-nut q2 is provided for locking the set-screw in an adjusted position.

The operation of the device is as follows: Air being admitted to the cylinder N above atmospheric pressure exerts pressure on the plunger O. The weight Q2 and the initial strength of the spring R are suficient to hold the valve P seated until themaximum desired pressure of the receiver is reached; When the pressure in the receiver rises above this point, the plunger O is forced outwardly, thus moving the valve P from its seat; but the needle-point remains in the supply-opening' m. The spring R is relatively quite short, so that its strength or tension increases as the plunger moves. Thus the plunger'O will occupy a given position with a given receiver-pressure, and a given capacity of opening by the needle-point o is effected. The air passing into the chamber M creates pressure in said chamber. There is a constant escape of air or fluid from the chamber M through the vent m. The pressure in the chamber M, therefore, where the capacity of the supply-opening m is less than the size of the vent is not very materially increased; but where the supplyopening is 'made considerably larger through the action of the plunger and the needle-valve then the pressure rises in the chamber M, and consequently in the cylinder L, in proportion to the difference in the relative capacities of the openings m and m. The

springs IAi increasing in strength produce a given pressure with a given positionof the piston 1n the cylinder L, so that with a given -pressure in the cylinderL the piston K will occupy a certain position in said cylinder,

thus giving to the yoke I a certain position,

and this acting through the lever G will control the valve B. The extent of movement of the valve B with a given movement of the piston K may be regulated by moving the fulcrum-blocls g3, or the amount of movement of the piston K may be regulated by varying the tension (any conve'nient means not shown may be used) or length of the springs If. The variation in pressure in the chamber M may be varied by varying the point p of the needle-valve. This may be made more abrupt or more gradual in its taper. Again, this variation in pressure in the chamber M relative to the change of pressure in the receiver may be controlled by adjusting the spring R. Where the'desired receiver-pressure is, for example, one hundred pounds and it is desired to keep this within one or two pounds of this pressure, it will be observed that the difference in pressure if directly applied to the piston K would not so overcome the frictional resistances of the parts as to effect a ready response of the piston. By using a secondary motor, as exemplified by the plunger O, with the supply and vent openings and varying the relative capacities of these the pressure operating upon the piston-K can be made to vary almost any per cent. desired, with a variation of two or three per cent. in the receiver, so that a positive yet sensitive movement of the a movement ofthe plunger O, while the spring R does this. The adjustment of the weight, therefore, is preferably used to change the moment at which the valve P is open-that is, the receiver-pressure which will bring th regulating ldevice into operation.

It will be noted that with the present structure a given receiver-pressure within the limits of pressure desired will maintain the piston K at a practically fixed. point so long as the receiverpressure 'remains constant. The consequent adjustment of the valve B is such as to give a constant supply to the receiver, so that if the outgofrom the receiver remains constant the parts will remain 'in one position.
