JERSEY OF WESTFIELD, NEW JERSEY, ASSIGNOR '10 WALLACE & TIER- CORZPORATION OF NEW APPARATUS FOR FEEDING SOLUTIONS 7 Application filed May a1, 1928. Serial no. 282,006.

This invention relates to solution feeding devicesr and one of its objects is to provide apparatus which will feed or dispense a solu- 0 for a water meter, also some of tion at a uniform rate as required.

Another object is to provide an apparatus for the purpose stated which is simple in construction, but which is nevertheless reliable and accurate in its operation.

Still another object is to provide an apparatus which will feedthe solution in proportion to'the rate'of flow of a current driving a motor. In the present embodiment the flow of current is the'flow through the motor of av water meter, but, as will. be apparent later on, the principle may be embodied in an apparatus in which the motor is driven by an electric current, spring, air pressure, or other force.

Still another object of the invention is the provision of solution feeding devices of the aspirator or suction types, withmeans for controlling the intake for the suction in such a way that the withdrawal of the solution from a container will be in proportion to the speed at which the motor is. driven. This construction is particularly desirable where the solution is to be fed in'relatively minute quantities andthe feed extended over a relatively long time interval.

The suction devices may clock mechanism such as is shown and described in an application Serial No. 282,005, filed the 31st day of May, 1928, by the present applicant, as well as by other forms of weight driven controlling devices. All claims to common subject matter are made in the other be controlled by a nism controlled by the motor for regulating or controlling the feed of a solution.

Fig. 2 is a side view of a form of the apparatus in which the solution'is drawn from a container by' the flow of water which -is metered by the metering part of the apparatus. j Fig. 3 is a Fig. 4 is a view of an apparatus of the same general type as shown in Figs. 1 and detail of the device used in the apparatus of Fig. 2 for effecting the suction.

2, but in which the suction is effected in a difl'erent way.

Fig. 5 shows still another form of suction apparatus.

Fig. 6 is a detail in-section of the devices used in the apparatus of Fig. 5 for efiecting the withdrawal of solution from a container by suction.

Fig. 7 shows, partly in section, the mechanism for feeding down the support for the movable suction intake.

Fig. 8 is a frontelevation, partly broken away, of the mechanism shown in Fig. 7.

Stated in general terms, the illustrative apparatus shown in the drawings comprises a water meter of standard construction, the

actuating devices of which are connected .to a train of gears leading to a reel. This reel, when driven by the gearing, lets out a cord or wire supporting the intake for a suction .device. The, gearing mentioned, as well as gearing in the actuating mechanism'of the 'motor,.permit the intake to descend at a very slow rate. This action may be insured, to a certain extent, by a weight on which the intake is supported. The suction is continuously maintained sothat as the intake is lowered the solution will be withdrawn in comparatively minute quantities, but which withdrawal is at a rate proportional to the speed of the. meter or rate of the flow operatingthe meter.

Described in detail and .with reference to the drawings, the apparatus includes a water meter of substantially standard construction actuated by water entering through 10 (Fig.

upon by the water current to turn the rotor.

and leaving through 11. In a chamber 12 is the usual rotor 13 carrying a blade 14 acted which, at each turn ofthe rotor, will give Projecting from the rotor 13 is a pin 15 one fourth of a rotation to a four-armed or toothed element 17 secured to a shaft 18. At-

tached to the upper end of the shaft 18 isa small gear 19 meshing with a larger gear 20 secured to a shaft 21. Attached to the shaft 21 is also a small gear 22 which acts through reduction gears 23, 24, 25 and 26 to drive a ear 27 attached to the lower end of a'sh aft 28. Fastened on the upper end of the shaft 28 is a gear 30 which drives a gear 31 connected to operate the usual water meter registering dials, which dials are'not shown but are contained within the casing 32 The gear 30 also drives a gear 34 rigid with a bevel gear 35 meshing with a companion gear 36 secured to the end of a shaft '37. The shaft 37. is journaled in a bearing sleeve 38 in the meter casing and has attached to it a clutch member 41 having slots in its hub engaging a cross pin 42 attached to one end of a flexible driving connection shown conventionally at 43. The other end of the connection 43 has fastened to it one end of .a sleeve 44, the other end of the sleeve being slotted to engage a cross-pin 45 on a shaft 46 projecting through the wall of a casing 47 containing another train of gears.

The water metering a paratus, represented generally by 12, may e supported at any convenient point for connection :by the flexible drive 43 to the shaft 46 ofv the second gear train, the casing 47 of that train being supported on the top of a pedestal 51 projecting from a platform 52 for the containers used for holding the supply of solution which is to be fed.

The gear train in the casing 47 resembles a clock mechanism and is supported between two plates 54 and 55 held in proper relative positions by the usual-separator rods 56 and supported as a unit by posts 57 attached to the wall of the casing 47.

The shaft 46, previously mentioned, is journaled in the plates 54 and 55 and carries a lantern gear 61 meshing with a gear 62 rigid with'a lantern gear 63. .Meshing with the lantern gear 63 is a gear 64 rigid with a pinion, WhlCh pinion is in mesh with a large gear 66 secured to a shaft 67. Spacing collars or hubs on the shaft 67 and at either side of the gear 66 prevent lateral displacement of the gear and shaft. 1

The shaft 67 carries a cross pin 71 cooperating with a slot across the end of a rod or tube 72, the other end of, 72 being also slotted to engage a cross. pin 73 on a spindle or shaft 74. The shaft 74'may be journaled (as shown in Fig. 1) directly in a head 75 formed on a projection 76 from the casing or the bearing a sleeve 77 which is formed on its interior to produce a short bearing 78 for the shaft 74 and has the rest of the interior slightly larger in diameter so as not to contact the shaft.

The sleeve 77 projects from the head 75 far enough to form a support for a grooved reel 81 for a wire or cord 82 (Figs. 1 and 2). Rigid with the reel'81 is a circular portion 83 provided with knobs or projections 85 by means of which the'reel may conveniently be turned by hand...

The face of the circular portion 83 is re-r cessed to form a compartment 86, with a further and smaller recess to form a seat for a washer 87 at the end of the sleeve 77, the compartment being closed by a circular plate 88 attached to the portion 83 of the reel winder and afi'ording a bearing support for the shaft 74.

Within the compartment 86 and fastened to the shaft 7 4 is a ratchet disk 91, the teeth of which are engaged by the nose of a spring pressed pawl 92 pivoted on a short rod 93 supported by the plate 88 and the circular portion 83 of the reel. When the reel devices are manually turned clockwise (Fig. 8) the pawl92 will ride idly over the teeth of the ratchet disk until the cord or wire 82 has been wound up to the desired extent, whereupon the pawl will serve to retain the reel in wound position.

The cord or wire 82 supports the suction the intake. This lowering may be insured or a partly effected by a Weight 96. It may be desired, occasionally, to lower the intake devices independently of the meter and gearing in order to establish contact between the intake and the solution, as, for ekample, when starting the feed after a re-supply of solution. 15* or this purpose the pawl 93 may be held disengaged from the ratchet 91 by means of a plunger 97, movable against a tail on the pawl, and held disengaged until a length of the cord 82 has been let. out suficient to ap ly the suction intake-to the supply of solut on.

Three, ofa number of forms of suction devices suitable for the purpose, are illustrated in the drawings. The apparatus" in vFig.2 comprises a tube 101 suspended from the weight 96 with the intake end 102 reduced to form a small suction nozzle. The upper end of the tube 101 is connected by a flexible tube 103 to a nipple 104 (see also Fi 3) containing a duct 105 terminating at t e restriction 106 of a venturi 107. The water outlet 11 of the water meter 12 maybe connected by suitable piping to the pipe 108 leading to the venturi so that the metered flow ofwater will cause the venturi to act to create a continuous suction through the duct 105, tube 101 and intermediate connections, so that whenever the intake 102 contacts with the surface of taining the venturi apparatus, so t at a part chamber or air exhaust (not shown) for cre-' of the main flow is caused to flow through the venturi to draw-in the solution and then carry it into the main flow. Both of these ways of operating a venturi are well. known.

In either construction the water meter will motor for lowering the suction intake being unwind the connection 82 to lower the intake 102 into contact with the surface of the solution in the container 111, thereby causing the solution to be applied in a definite proportion to the flow'metered.

In the construction.illustrated in Fig. 4, the intake tube 113. is supported from a weight 114 lowered by operation of the water meter 12, and is connected by a flexible tube 115 running Leadin from the chamber 116 is a tube or pipe 11 connected to any suitable vacuum ating a constant suction atthe intake end of the tube 113. Also leading from the exhaust chamber 116 is a tube 118 having its lower end extending into a receptacle 119. When solution is drawn into the exhaust chamber 116 by the suction applied through the tube 117 the solution will separate from the air when it reaches the chamber and flow through the tube 118 into the receptacle 119.. It is preferred to have the receptacle 119 practically filled at all times so as to form an air seal. The wall of the containeris provided with an overflow or outlet, shown more or less conventionally at 121, from which it is conducted in any suitable way to the point of final application.

The apparatus illustrated in Fig. 5 is intended for use in a system where the feeding suction is created by an air current. In this instance the suction intake for solution is at the lower end of a small tube 123 (see also Fig. 6) attached to a nipple 124 containing a duct 125 terminating at the restriction 126 of a venturi throat 127. Leading into the venturi is a tube 128' connected by a flexible tube 130 to a source of air pressure. Leading from the other side of the venturi is a tube 131 sup ported from a weight 132 lowered by opera: tion of the water meter 12, the tube 131 being connected by a flexible tube 133 to a chamber 134. In this chamber the air is freed from any solution carried by it and leaves through the air outlet 135. The solution settles to the bottom of the chamber 134 and leaves through an outlet 136. Associated with the outlet 136 is one end 137 of connections of any desired form for conducting the solution to the point 0 application.

In each of the constructions described-the to an exhaust chamber 116.-

tainer over a time interval is directly proportional to the flow metered during that 1nterval. This gives a highly satisfactory result particularly when the solution is a sterilizing solution to be applied to a main flow of water.

It is obvious, however, that instead of the the motor of a water meter, it may be an electric motor operating to' lower the intake through reduction gearing, or the weight may be used to drive a clock mechanism as shown in application Serial No. 282,005 above referred to, or the weight may be lowered by a train of gears driven by the weight and controlled as to speed by any of several well known forms of governor or regulator.

While the constructions shown and described specifically and in general terms are admirably adapted to primarily stated, it is not thedesire to be limited to those constructions, as the invention is capable of various embodiments, with suitable alterations and changes in construction, all coming within thescope of the claims which follow.

What is claimed is:

1. An apparatus for feeding or dispensing solutions comprising a water meter,a train of gears actuated\,by the meter, a weight lowered by the meter through. connections including said train of gears at a rate proportional to the flow through the water meter, a container for the solution, a suction device including a venturi for producing the suction, and a flexible connection between the suction device and the container comprising an intake for the solution moving with the aforesaid weight. p
