The partition'15 divides each of the compartments into a receiving chamber 18 and a discharge chamber 19 and arranged tojpro ject into the receptacle 11 is a discharge pipe 20 which is maintained in a 'fixed'position with respect to the'pivot is. supplied to the receptacle g 12 of the receptacle 11 andthrough which pipe 20 the material chambers 19 and'prefer'ably' adjacent the re 7 spective ends 16 is a discharge outlet 21 and a chute or nozzle 22 is preferably providedrial from the outlet. 7

Eaohof the-outlets 21is provided with a closure 23 preferably of which is arranged toimove in guides and is provided with a laterally projecting portion 25 and the' closure 23'is normally held in adjacent the outlets for directing the matea closing position with respect to theopening 21 preferablyby means of a spring 26, one

end of which engages the projection 25 and the other end abuts a shoulder 27 carried by the receptacle 11.

The receptacle 11is adapted tobe swung about the pivot 12 so as to position either one Q,

or the other of the receiving chambers 18 in a position to receiveithe material from the pipe 20. according to the direction of movement of the receptacle about its pivot As one of the discharge outlets 21is moved into. a M

position. to dischargethe contents of'the chamber 19' intoa can 'or container '28 the other outlet 21 will be moved out of a discbarging position; and as the respective outlets move out dlscharging positlon, the respective springs 26 will shift the closures 23 to close said outlet. I I p As the dischargeoutlet 21. approaches a discharging position the projection 25 on the respective outlet will engage a stop or member 29 arranged inthe path of the projection the slid able type t 45 Y by-anelectro-responsive device 48, preferably and which stop operates to shift the clo- I sure 23 against the stress oi the spring 26 to uncover the outlet 21.

Any suitable means may a' suitable and eflicient means embodies a sprocket wheel 30 to which is connected one end 015a link 31, the other end of the link being connected as at 32 with the receptacle so that when the sprocket wheel 30 is rotated 7 in the direction indicatedibythef arrow-in Figure 1', the receptacle 11 will be rocked known construction,

first into the position shown in Figure 1 and I I later into the position shown injFigure 4.

.- The sprocket wheel is adapted to bedriven from a motor '33 through the medium of a speed reducer 34 of any {suitable or. well and the shaft 35 of which speed reducer is connectedby means of a belt 36with the shaft 37 of the motor.

. Connected with thelshaft 35 of the speed reducer is a pulley, over which another end less belt 38 passes, and this belt'in turn passes over a pulley 39 rotatably mounted upon the supporting" structure 10.- Secured to the the .operation'ot themot'or 33. r

Loosely mounted upon the shaft40 is a sprocket wheel/42 over which a sprocket chain 143 passesand which sprocket chain also passes over the sprocket wheel '30.

f Connected to; rotate withthe sprocket wheel 42 is a disc44 and pivotally mounted upon the disc intermediate its ends as at 45 is a locking dog 46 provided with: a spring 47 hat tends normally to move the dog 46, into engagement withfthe locking member 41 to lock the disc 44' andthe sprocket Wheel42 thereby with the shaft40' for rotation therewith and in the form of a solenoid, the armature 49 of which is operatively connected with one endof alever 50, the latter beingop'ivotally. supported intermediate its ends as at 51. One end of the lever 50 is adapted to be moved into the. path of rotation of a portion of the Y46 and aspring 52 tends normally to move'the lever 50 into such position so that when the disc.,44 islocked for rotation with he shaft40, and the dog '46Yis-bodily rotating withthe disc, one end of the dog will contact with the end of the lever 50 which is arranged infthe path of movement thereof to trip the dog againstthe stress of the spring 47 and thereby unlock the disc 44 ,with're spect' to the shaft 40 to arrest the rotation of the sprocket wheel 30: A retaining pawl 53 may be providedfwhich co-operates with a shoulder- 54 on'thedisc44-fo'r locking the disc be provided 'for rocking the receptaclell about its pivot, but

tion the material to be to the impart a rotationwto the sprocket wheel30 fromthe motor. T V j 'The operation of thedog 46'is controlled brought into rated contacts 64- 44 against retrograde movement whenthe dog 46 1s moved into an lnoperative or unlocking position with respect to the member 41, a spring 55 being provided to retaining pawl 53. I

The receptacle 11 will thus be rocked about itspivot to alternately dischargethecontents thereof into thecans or containers control the "28, p which latter are mounted upon a suitable support 56 and the rocking of the receptacle 11 is automatically controlled by the delivery of respective chambers 18.

In the present application'of the invendispensed is disclosed the liquid or material to be dispensed into the o as aliquid which, when the parts arein the position showninFigureB, will fill one off the chambers '19 by-being discharged through the space between the transverse partition 14 and the end of the respective inclined partitio'n' 15-,a vent pipe 57 beingfprovided for each of the chambers 19.

Assoon as one ofthe chambersilfil is filled with the liquid, any additionalamount delivered into the receptacle 11 will flow over the partition 14 and intoone ofthe receiving chambers 18 to accumulatetherein andthe accumulation of the liquid will operate or raise a float 58 connected with a. rod 59 that moves in suitable guides 60. One of these floats and an electric circuit make and break device, hereinafter to be described, isasso: ciated with eachof the chambers 18 andthe respectivefloatswill rise and fall according" quantity of liquid in the chambers 18."

These float devices, operate to control the electro-responsive device 48 through the medium of contacts 61- 62. To the contact 61 is connected a conductor 63'Lwhich is also connected to'a contacti6i4. Acontact 65 is spaced from the contact 64 and co-operates therewithin a manner to be described, and

connected with this contact 65- is a conductor ,66 which: leads from one side of a suitable source of-supply,- such as-a battery 67. 7 Leading from the other side ofthe battery is a conductor 68 which is connected to one end of the winding ofthe electro-responsive device 48. v I 1 Connected to the other end of the winding of the electro-responsive device is a conductor 69 which is also connected with a contact 70, the latter being disposed in a position that when the float 58 rises the contact62'will be engagement with the contact70, thereby completingthe circuit through the electro-responsive device 48 and the sepa manner. I

Connected for rotation with the vpulley '39 is a disc 71 formed'ofany suitable insulating material such as fiberor the like and carried in the following by the disc is a contact 72 which passes through the disc and is exposed; onboth sides thereof. This disc 7i operates between access;

machine will be clearly understood from the foregoing description, but briefly stated it is as follows a Assuming the parts'to be in the position- -20 shown in Figures 1 and 3, and liquid is being supplied through the pipe 20,the liquid will accumulate in the compartment 19 which is elevated until the compartment 19 is filled, as shown in Figure 3.1.

During the filling of thiscompartme'nt the: liquid will be discharged from the compart ment 19 which is lowered and any surplus amount of liquid will flow over the partition 14 into the other chamber 18. As the liquid flows out of the chamber 18 which is elevated and into the chamber 19 as shown in Figure 3, the float 58 in that chamber will be lowered, thereby moving the contact 62 away from the contact 7 O to break the circuit through the electro-responsive device 4 8. This will render the electro-responsive device inactive so that the spring 52 will position the end of the lever 50 in the path of movement of a portion of the dog 46 to cause the discs 4 1 and 71 to be locked for rotation with the shaft 40 to shift the receptacle 11 from the position shown in Figure 1 to the position shown in Figure 4. V I

As soon. as the other or filled chamber 18 is raised, the float 58 will be held raised until the liquid flows from the chamber 18 into thechamber 19 sufliciently' to cause the float to drop to move the contact 62 away from the contact 70. 4 It has been found that in operation, a considerable amount of electricity will be consumed in a days operation of the device if the circuit to the electro-responsive device is not promptly broken after the receptacle is shifted, and it has also been found'that the contact 62 will not always promptly move out of engagement with the contact 70. Therefore, in order to conserve the amount of electricity employed and to insure a prompt breaking of the circuit through the electroresponsive device 48 the additional make and break device 64,-65-72 is provided.

The circuit for the other chambers 18 and 19 and float 58 is the same as for the float device just described.

In order to remove the receptacles 28 after i While the preferred form of they have been-filled, a suitable conveyor 73 maybe provided.
