Secured to the rear end of said lever 50, and insulated therefrom, isa depending contact arm 53, the lower end of said arm adapted to engage a contact plate 54. Mounted on the contact plate 54 is a binding post 55. Mounted to the con tact arm 53 at the upper end thereof is a binding post 56. y 7

Connected to the receptacle 5 by a nipbeing adjustably mounted to a stand 59 by the threaded pipe 60. Mounted in the float Secured to the upper end of'saidfloat and extending vertically therefrom is a rod 62, said, rod bemounted in the cylinder These contact points 71 are adaptedto' -make contact with the contacts 69.

Adjustably mounted on the rod 62 ofthe float 61 is a lifting'member 73, said lifting member adapted to .beladjusted' on said rod by the set screw 74. In connecting this improved device in circuit with the. line wires wire and to the binding posts 67 of the gage bar 64. Leading from the binding post 68,

from said magnet is a wire 79 which leads to'the binding posts 56.

In theoperation of this improved device,

58-, said cylinder Secured to said horimember 70 are i which are cone- 'nected with each other by the wire 72.

75, a wire'76 is led from one of said" line wires to the; binding posts 55, and a wire 77 is connected with the other saidline,

\ adjacentthe binding post 67, isa wire- 7 8 which leads to the magnet 47. Leading if a predetermined amount of water is to be obtained in the receptacle 5, the gage or lifting member .73 is set on the rod 62 in accordance with one of the characters of the gagebar 64. The valves 29 are then set in open position by lifting the handles 34 of the rock shafts 32 to a horizontal position. In this position, the handles will be engaged by the engaging portions 41 of the pawls 40. This movement of the handles 34 will also set the portions 42 of said pawls .in a horizontal positionagainst the'bifurcated portion 53 ofthe knock-off bar 52.

The lever 50 will then be-disengaged from the magnet 47. Fluid will then pass through the supply pipes 2 and 3. and will be conducted through the vertical passageway 18 to the receptacle 5. As the fluid rises in the receptacle 5, an equal amount will be registered in the fluid cylinder 58, and the float 61 will be carried upwardly until the member 73, which iscarriedby the rod 62, will engage the under side of the hinge 70, thereby'elevating said hinge. The contact71 will engage the contacts 69 thereby closing the'circuit andenergizing the magnet 47. The lever 50 will then be moved downwardly, and the knock-0E bar 52 will bear against the disengaging portions 42 of the pawls '40 thereby disenaging the. ends42' from the notches 37 of the handles 34. 'As the handles fall downwardlyby their own weight, thecams 33 of the rock shafts 32 will become disengaged from beneaththe lower end of the valve stems 28, thereby allowing the valves 29 to be returned'totheir valve seats. The instant the lever 50 engaged the magnet 47, the electric circuit just made was again broken by the swinging of'the contact bar '53 from the contact plate 54. handles" 34 move downwardly they will engage against the stoplugs 80 which are formed on, the housing 6. The spring actu- As the 41 of said pawls riding on the riding faces 36 of the handles 34. When the valves 29 are elevated from their seats, they are moved into the chambers 25 of the regulating valves 24; When the valves are released, they will not come down with force on their respective I seats on account of'the vacuum producing portions 31'producing a vacuum. in the chambers 25.

As shown in the drawings, in order to establish a proper temperature of fluid in the receptacle 5, a thermometer 81'. is mounted in the opening 82 which is formed adjacentthe spiral vanes 19. It might be necessary to regulate quickly the supply of hot fluid from the pipe 3 in accordance with the amount of fluid being discharged from the pipe 2 or vice versa. This is done by 3 manipulating the hand wheel 23 of either of the regulating valves 24, thereby lowering the valve toward its horizontal seat ng portion 14 of the valve seat 12. Attention is called to the fact that the valves 29 are elevated the same distance every operation in accordance with the height of lift given by the cams 33 of the rock shafts 32. There fore, the amount of fluid discharged from the supply pipes is controlled by the regulating valves 24. As the discharged fluid engages the spirally arranged vanes 19, the different temperatures of the discharging fluid will be thoroughly mingled so the proper reading is given by the thermometer so the operator can readily judge how to regulate his regulating valves.

Attention is called to the upper end or starting point of the vanes 19 in whichthe starting portions 83 are in longitudinal alinement with the bottom of the discharge chamber 17 As there are two spirally arranged vanes 20, this position of the vanes provides means for portions of the fluid from each of said dischargechambers 17 to fall on one of the vanes 20, while other portions of the fluid will fall on the other vane 20. The portions from the chambers will unite, thereby providing for a thorough mixing of the fluid. In addition to the recipro'catory mounting of the inlet valves 29 in the chambers 25 of the regulating valves 24, Which assembling causes a vacuum to be produced in the chambers 25, the valve 24 also serves to prevent fluid pressure on the top of the valves 29.
