siphon tube 140. The aperture 142 is shown aligned
with the siphoning tube 140 but the same may be mis

the purpose of interlocking adjacent cylindrical members
66 and thus reducing the number of coins necessary to
operate the cam 70.
Mounted on the outer end of the shaft 62 is an operat—
ing knob 74 with the knob 74 being provided with an
axial bore 76 receiving the coil spring 78 and a spring de
tent 80 with the outer end of the bore 76 being closed
by a’ screw ‘threaded plug 82. A fastening member 84 is
threaded into the end of the shaft 62 for retaining the
knob 74 on the shaft 62. A cam member 86 is provided
on the shaft 62 and is engaged with the spring urged de
tent 80 and also is engaged with lugs or notches on the
knob 74 with the lugs or notches being designated 88.
The lugs or notches 88 on the knob 74 engage a stop
member 90 mounted on the front wall 20 which limits ro
tation of the knob 74 to approximately 90°. With the
detent 80 engaging one axial face of the cam designated
by the numeral 92, the cam 86 can be caused to rotate
municated with the area or space between the inner sur
face of the cylindrical member 128 and the outer surface
of the annular ring 120 below the seal 126. The depend
ing stud 134) on the outer cylindrical member 128 is slid;
ably received in a vertical sleeve 144 having a notch 150
therein. Attached to the stud 1‘39 and extending out
wardly through the notch 150 is an opening arm 152 rest~ -
ing against an adapter plate 154 on the upper endof a
compression coil spring 156. The lower end of the coil
compression spring 156 rests against an adapter’158 on
the base of the casing. The outer end of the arm >152 en

counterclockwise for riding the Spring detent 86 up the
ramp 94 of the cam until it drops behind another vertical
face 92 after which the knob 74 may be rotated another
90° for turning the shaft 62 another 90° thus completing

principles of the invention. Further, since numerous
modi?cations and changes will readily occur to those
skilled in the art, it is not desired to limit the invention
to the exact construction and operation shown and de

equivalents may be resorted to, falling within the scope
of the invention as claimed.
What is claimed as new is as follows:
1. A dispensing device comprising a casing, a container
detachably mounted on said casing, said container hav
ing an open end facing downwardly, vertically reciprocal
syphon tube movable with the receptacle whereby liquid
will be discharged from the receptacle by the syphon
tube when the liquid level in the receptacle is raised in
relation to the syphon tube whereby the syphon tube dis
charges a quantity of liquid to bring the liquid level in
the receptacle to a predetermined level in relation to
the syphon tube.
7. The combination of claim 6 wherein means is pro
vided for limiting the downward movement of the re
ceptacle for controlling the quantity of discharge from
the syphon tube when thereceptacle is depressed.
8. The combination of claim 6 wherein said casing is
provided with a discharge adapter having an inclined
discharge tube therein, a block on the inner surface of
said casing and having the tube extending into the wall
