To all whom it may concern:

The reduced portion J is preferably in the form to be readily placed in, or removed from looking position.

With the parts in the position shown in Fig. 1, in order to remove the plug from the valve body it is only necessary to impart a slight downward movement to the handle U, at the same time drawing the locking plate laterally, after which the plug can be removed from the valve body. The construction affords an extremely simple arrangement which can be manufactured at a reasonablecost and can be readily operated. The parts are so arranged that they can be quickly separated for purposes of cleaning, and the structure is entirely practical for use with liquid foods such as milk,

from the standpoint of sanitary requirements.

I claim as my invention:

1. The combination with a valve body, of a rotary plug having a reduced lower end, a removable locking member slotted to engage said reduced end of the plug and adapted to be positioned against, the valve body, said locking member being recessed on its upper surface to engage the valve body, a shoulder at the end of the reduced portion of the plug, a follower arranged on the plug above said shoulder and having an inwardly directed flange at its top, and a Copies of this patent may be obtained for spring positioned between said shoulder on the plug and the flange on the follower.

2. The combination with a valve body, of a rotaryplug, a locking member slotted to engage the plug, said locking member being disposed between the valve body and the lower end of the plug and provided with a handle or projection whereby it can be positioned or removed, a follower arranged on the plug and engaging said looking member, and a spring cooperating with the follower.

3. The combination with a valve body, of a rotary plug, a locking member slotted to engage the plug, said locking member be ing disposed between the valve body and the lower end of the plug and provided with a handle or projection whereby it can be positioned or removed, a follower arranged on the plug and engaging said locking member, and a spring cooperating with the follower, the follower embodying a housing for the spring.
