of parts hereinafter shown, described, and

claimed.

Figure 1 is a front elevation of my improved device, parts thereof being in section to more clearly. illustrate the same. Fig. 2 is a side elevation of the device. Fig. 3 is a plan view thereof. Fig. 4 is an enlarged cross-sectional view taken approximately on the line 4 4 of Fig. 3. Fig. 5 is a horizontal sectional view taken approximately on the line 5 5 of Fig. 2. v

Referring by numerals to the accompanying drawings, 1 indicates a suitable base, to

, openings is a valvecomprising two end disks 7, intermediate of which is the central disk 8,'said disks being connected'by the webs 9. Discharging. into'the centralone of the con1- partments within thevalve-casing is a suitable connection 10, through which fiuid under pressure is discharged into said central chamber, and leading from the chambers immediately above and below said central chamher are suitable tubular connectionsll, the same leading to the valve or other mechanism that is operated bymy improved device.

Leading from the top and bottom chambers within the valve-casing are suitable tubu lar connections 12, that combine with or are connectedto a waste or discharge pipe 13. Formed integral with the left-hand side of the valve-casing 4 is a laterally-projecting arm I 14, through which is formed a screw-threaded aperture, in which operates the exteriorlyscrew-threaded lower end of a vertical post 15, the same being provided with an integral disk 16 adjacent its upper end. Seated in the upper end of this post is a pin 17, that forms a fulcrum for a horizontally-arranged arm 18, one end of which projects to a point directly over the center of the valve-casing 4, and a suitable connection 19 is made from said end of the arm 18 to the upperend of the valve that operates within said valve-casing. A stufi'ing-box 20 is located in the top of said valve-casingaroundthis connection 19. Upon the opposite end of this arm 18 is adj ustably located a weight 21, which counterbalances the weight of the valve within the'valve-casing 4, and passing through said arm at equal distances on each side from the fulcrum thereof are screw-threaded pins 2:2, with the lower ends of which are formed integral the heads 23, into which screw the contact-points 24, thatlie immediately over the face of the disk'16. A pair of. ears 25 are formed integral with the top of the arm 18 immediately above the fulcrum thereof, and between said cars is fulcrum ed' a horizo'ntallyarranged tube 26', the ends thereof being closed by the caps 27 and 28 -and there being a ball 29 located within said tube. Formed integral with the cap 28 is a ring '30, through which ing-nuts 32 are located upon said screwouter end of which carries a contact-point 39, that is positioned immediately above the right-hand one of the contact-points 37, and adj-ustably held immediately above the lefthand one of the contact-points 37 is acontactately above the arm 33 is a short arm 38, the

point 40. An electrical conductor 41 leads from the arm 38 to one pole of a suitably-lo cated battery 42 and from thence to one of the binding-posts of an alarm-bell 43, and another conductor 44: leads from the opposite binding-post on said bell to the end of the arm Leading from the contact-point 40 to the conductor 41 is a short conductor45. Passing through the ring 35 on the end of the arm 33 is the screw-threaded lower end of a vertically-moving rod 16, the same being provided with adjusting-nuts 47, one above and one below said ring 35.

Assumingthatthe parts are balanced or are in the positions shown in Fig. l and that the rod 31 is moved upwardly when the lower nut 32 upon said rod strikes the ring 30, carried by the cap 28, said ring and cap, together with the end of the tube 26, on which said cap is located, will be elevated and the ball 20 will roll to the opposite end of said tube. lVhen this movement takes place, the side of the tube into which the ball has rolled will engage against the upper end of the left-hand one of the adjusting-screws 22 and will depress the same, which will look the bar 18 upon the pivot-pin l7, throwing the weighted end downwardly until the left-hand one of the contact-points 2i strikes against the disk 16, and this movement necessarily raises the opposite end of said bar 18 and elevates the valve within the valve-casing. As said valve is drawn upwardly in said valve-casing communication will be established between the chambers into which the inlet pipe 10 leads and the chamber immediately below said first-mentioned chamber and at the same time communication will be established be tween the chamber immediately above the chamber in which the inlet-pipe 10 leads and the top chamber or the one from which the discharge pipe 12 leads. Consequently if compressed air is passing through the valve said compressed air will enter the pipe l0,to be discharged therefrom into the central one of the chambers between the partitions 5, and pass from thence downwardly into the next adjacent chamber, from thence through the top one of the tubular connections 11 and be delivered to a point where it is desired to utilize said compressed air, and simultaneous with this action the opposite pipe 11 becomes an exhaust-pipe and the back pressure through said pipe discharges into the chamber above the central chamber, in which'the pipe 10 discharges, and from thence the compressed air discharges into the top chamber and through the discharge or exhaust pipe 12. When the rod 31 moves downwardly, the nut 32 thereon will strike against the upper side 01": the ring 30 and a reverse movement of the parts just described will take place and the valve will be lowered, so that the top disk 7 closes the opening through the top partition 5, the central disk 8 closes the opening in the partition immediately below the central chamber, into which the inlet-pipe 10 leads, and communication will be established between the two lowermost chambers and between the central chamber and the one immediately above it. The distance that the rod 31 has to move before the tube 26 is ac tuated is regulated by the adjusting-nuts 32 upon thescrew-threaded portion of said rod. It is essential that the movement of the rod 46 be simultaneous with that of the rod 31. The adjusting-nuts 47, located upon the rod 46, are normally farther apart than are the adjusting-nuts 32 upon the rod 31, said nuts being so located as that they will not engage the ring 35 on the end of the fulcrumed arm to sound the alarm until after the valveoperating mechanism has actuated. Thus the alarm is sounded only at a time after the valve has been actuated, and the rod 31 continues to move upwardly or downwardly, as the case may be, thereby endangering breakage of the various parts of the valve-actuating mechanism. When the rod 46 continues in its upward movement, the lower one of the nuts a? thereon will strike against the under side of the ring 35, thus raising said ring and the end of the arm 33 upon which said ring is located, and as said end of the arm moves upwardly the right-hand one of the contactpoints 37 will engage against the contact-point 39, thereby closing the circuit through said arm 33, bar 38, conductor 4.1, battery 42, bell 43, and conductor 44. When the rod 4:6 descends past its normal lowered position, the upper one of the nuts 47 will engage upon the top of the ring 35 and a contact will be made between the left-handone ofthe contact-points 37 and the contact-point 4.0, thereby closing the circuit and sounding the bell 4E3. The operator or attendant will immediately know that the rod 31 is not operating properly when the bell sounds.

A device of my improved construction is especially applicable for use in connection with thermostats, which thermostats are used to elevate the rods 31 and 46, and the compresed fluid that passes through the valve may be led to and through the valve that is located in the pipe that supplies the hot air, water, or steam to the heating system in the build ing in which the valve-operating device and alarm are located.
