in its entirety by the reference character A and includes a valve structure B. The valve structure B comprises a valve body Ii) having a valve member II therein formed with a chamber I2 in the same. In this chamber is provided one or more agitators I3 carried by an electric motor I4 which is mounted on the valve member il. By means of this construction the liquid passing through the valve A is agitated by the agitators I3 during the iiow thereof through the Valve. These various parts will now be described in detail.

The valve body Iii is conical in form and is formed with a frusto-conical bore it which is situated vertically and which is open at the top and bottom. To the lowermost portion of the valve body IIJ is attached a spout I1 which is also conical in form, being constructed with a flaring wall I8 and with a tapered wall hl iollowingalong the outer surface 2| of the body I6. The Wall I9 is received within a recess 22 in the lowermost portion of the Valve body I6, and is held in place by means of two pins 23 attached to said valve body and disposed in the recess 22, which pins are adapted to enter bayonet slots 24 in the wall I9 of the spout I1. The spout I1 has a chamber 43 in the same which communicates with a discharge outlet 25 from which the liquid dispensed is discharged. At the uppermost portion of the Valve body I6 is provided a boss 26 which has.a passageway 21 therein. This boss is threaded at 28 to screw on to a pipe or tting 29 which may be connected to a reservoir or othersupply of the liquid to be dispensed. The passageway. 21 terminates in a port 36 extending through the wall of the body I6 formed by the bore I6 and which forms an inlet for the valve structure B.

Within the bore I6 of the body I6 is disposed the valve member Il which is cup-shaped in form and which has a frusto-conical surface 3| adapted to closely t along the surface of the bore I6. This valve member has a relatively thick bottom 32 and a fairly thick circumferential wall 33 which form the chamber I2 Within the same. Said valve member is open at the top and is constructed with a neck 34 projecting up- Wardly therefrom, andl which lies inwardly of the surface 3I of the wall 33 to form a shoulder 35 therebetween. In the bottom 32 of the valve member II is drilled a hole 36 which provides a port 31 communicating with the chamber I2. A radially extending hole 38 communicates With the hole 36 and extends through the surface 3l of the said valve member. This hole communicates with a groove 39 extending along the surface 3I, which groove in one position of the valve member I I, is adapted to communicate with the port 36 of the passageway 21. It will be readily comprehended that, when the valve member II is in the position shown in Fig. 2, the liquid to be dispensed may iiow through the passageway 21 along the groove 39 and through the

holes

38 and 36 and into the chamber I 2.v The valve 'member I I is further constructed with ports or holes 4I in the circumferential wall 33 thereof, which are situated at about the same elevation as the port 36. These holes communicate With grooves 43, which are formed in thewall 33 and extend through the surface 3I of the valve member Il. These grooves extend through the bottom 32 and bring the interior of the chamber I2 at a locality considerably above the bottom thereof in communication with the chamber 43 formed within the spout I1. When the parts are arranged, as shown in Fig. 2, the liquid entering the chamber I2 rises to the elevation of the ports 4I and is discharged outwardly therefrom and along the grooves 42 into the chamber 43 and nozzle I1. The said liquid then. leaves the nozzle through the discharge outlet 25 thereof. It will thus be readily comprehended that the various parts of the valve body and valve member form a conduit through which the liquid flows from the receptacle to the discharge spout I1, and that the flow of liquid is cut off at the port 36. It is also to be noted that the chamber I2 constitutes an enlargement of a portion of said conduit.

f Encircling the neck 34 of the valve member II is a sleeve 44, the lower edge of which rests upon the shoulder 35 of said valve member. This sleeve has a keyway 45 therein which is adapted to engage a key 46 secured to the valve member II. The key 46 is attached to said valve member by means of a pin 41 and may be soldered or brazed to the said valve member. The key 46 also forms a limiting device for limiting the rotation of the valve member II. For this purpose two

stops

48 and 49 are employed which consist of pins set into the upper portion of the valve body I6. These pins are so situated that the valve member II, when in its open position, as shown in Fig. 2, engages the pin 48 and when in its closed position, as shown in Fig. 6, engages the pin or stop 49.

The sleeve 44 has attached to it a mounting 5I which is secured thereto by means of rivets 52. This mounting is formed with a threaded boss 53 adapted to receive the shank 54 of a handle 55. By means of this construction the sleeve 44 may be rotated. Due to the key 46 and the keyway 45, rotation of the sleeve 44 causes rotation of the valve member II.

The motor I4 may be of the conventional type, being constructed with a core structure 56, which is clamped between

end bells

51 and 58. These end bells journal the armature shaft 51 of the motor to which the agitators I3 are attached. The shaft 51 is of such length that the agitators I3 become positioned beneath the ports 3I and above the bottom of the valve member II Within the chamber I2 therein. These ag'itators, when the motor is operated, introduce air bubbles into the liquid passing through the chamber I2 which give the liquid a foamy form when leaving the ports 4I. To prevent rotation of the liquid and render the agitators I3 more ecient, two swirl breakers 58 are employed which extend along the inner surface of the valve member and are disposed within the chamber I2.

The motor 51 is attached to the sleeve 44 by means of a flanged mounting 59. This mounting has a tubular portion 6I which extends into the uppermost portion of the sleeve and a flange 62 attached to the end bell 58. The tubular portion 6I has secured to it a stud 63 which is provided with a nut 64. Nut 64 has a conical end v65 adapted to engage in a conical socket 66 in the upper portion of the sleeve 44. Aslot 61 in the said upper portion of the sleeve receives the stud 63 and permits of inserting the tubular portion 6I into the said sleeve. When the nut 64 is tightened the parts are held in locked Vposition.

The valve body I6 of valve B is constructed upon the inner surface of the bore I6 thereof with a groove 68, best shown in Figs. 6 and '1, which is disposed in circumferentially spaced relation to the port 29 and which is situated at the lowermost portion of said valve body. This groove is adapted to communicate with the hole 38 in the valve member II and also with the chamber 43 within the spout I1, when the valve member II is in closed position, as shown in Fig. '7. In such position the port 36 is covered up and the hole 38 brought into communication with the groove 68. This permits the liquid within the chamber I2 to drain out of the same and to be discharged through the spout I1 along with the liquid normally passing through the ports 4I. In this way the device is completely .emptied of liquid.

The operation of the invention is as follows: Normally the valve member II is in closed position as shown in Figs. 6 and '1, and no liquid passes through the same. When the valve member is rotated by means .of handle 55 to the position shown in Fig. 2, liquid flows through the passageway 21, the port 36, groove 39 and holes 38 and 36, and port 31 into the chamber I2. Upon energization of the motor I4, the agitators I3 are set into action which beats up the liquid within the chamber I2 and aerates the same. The liquid so acted upon passes outwardly through the ports 4I and along the grooves 42 into the chamber 43 of spout I'I from which the liquid is discharged through the discharge outlet 25. When the valve is closed the residue of the liquid Within chamber I2 drains out through the holes 36 and 38and the grooves B8 into chamber 43 of spout I'I from which the same is discharged out of the spout together with the liquid entering said chamber through ports 4I. When it becomes desirable to clean the device, the spout I1 may be removed by rotating the same and disengaging the pins 23 from the bayonet slots 24. The valve member II may next be raised out of the bore I6 of the valve body ID and the sleeve 44 disconnected therefrom and motor I4 removed from the sleeve. All of the parts which come in contact with the liquid are thus readily accessible and may be Washed and cleaned.

The advantages of our invention are manifest. Our improved dispenser may be used for dispensing and aerating, stirring or mixing milk or milk products such as malted milk or may be used with any viscous liquid requiring stirring, mixing or aeration. The device is extremely simple and practical in construction. With our invention the liquid to be dispensed is agitated as it passes through the valve. Due to the construction and arrangement of parts our dispensing device is extremely sanitary and may readily be taken apart for the purpose of cleaning. By constructing the valve member with grooves, upon the exterior surface thereof, the same is readily cleaned and all of the liquid adhering to the same may be readily removed. Our invention may be constructed at a nominal cost and may be used with any container or receptacle in which a liquid to be dispensed is contained.

Changes in the specic form of our invention, as herein disclosed, may be made within the scope of what is claimed without departing from the spirit of our invention.
