This invention relates to vending machines
operable in response to insertion of a coin of
certain dimensions.
Objects of the invention are to provide a de
v5 vice of the class described which (a) is adapted
to contain a supply of and deliver for a single
coin and by a single operation a plurality of arti
cles of different shapes and sizes but which are
designed for conjoint use such as a paper cup
and a predetermined number of medicinal tablets
to be taken with water in such cup; (b) shall be
compact, convenient, simple, economical and ef
ficient in construction and operation; (c) shall
be eñìciently safe-guarded against “milking”, i. e.
unauthorized extraction of contents; (d) shall
at all times show at a glance the number of
tablets remaining in the container and (e) shall
protect the contained tablets from damage or
atmospheric deterioration.
With these and other objects in view, `all of
which will more fully hereinafter appear, my
invention comprises certain novel constructions,
combinations and arrangements of parts as will
be hereinafter fully described and claimed and as
r25 illustrated in the accompanying drawings in
which like characters of reference -indicate cor
responding parts throughout and in which

The Figures 10, 11 and 12 areon a relatively
enlarged scale.
My invention is designed for ythe vending of a 5
paper cup and two medicinal tablets- and will
be described interms of such construction and
use though, obviously, the number of Y tablet
containing and dispensing units may be increased
or diminished as desired in order to vend, with l0
a single cup, the number of tablets desired for
a standard dose.
My invention comprises a back 20, to be at
tached to a wall or other support in any suitable
manner, not shown, to which back I attach a 15
housing 2| preferably by hinges 22 and lock 23. ’
The principal part of the mechanism is mounted
in and carried by the housing 2l, a few parts
beingcarried on the back 20 and thereon posi
tioned to cooperate with certain parts carried 20
in the housing when vthe-device is closed.
Exteriorly, the housing is provided with a cup
rem'oving opening 24, a tablet removing opening
25, windows 26, a coin-chute housing 21 having
a coin slot 28 therein,and a plunger bar 29 having 25
push button 30.
Interiorly of the housing and above the open
ing 25 I provide shelf 3| suitably supported on
the walls of the housing and covering a coin box
33 having receiving chute 33a and slidably sup- 30
ported by flanges 33h on brackets 32. Gaskets
34, of rubber or other suitable material, for seat
ing and sealing the lower ends of the tablet tubes,
later described, are carried by shelf 3| which
shelf is also provided with holes 35 and 36 aligned 35
between the gaskets and for the purposes here
inafter described.
Tubes 3l, preferably of glass, normally have
their open lower ends seated upon gaskets 34,
the tops of the tubes being covered by caps 38, 40
the capped upper ends of the tubes having a loose
sliding fit within cylindrical guides 39 depending
from the top of housing 2l.
Resilient means, as
springsliû within the guides 39, are provided for
normally holding the lower ends of the tubes 45
tightly against gaskets 34.
Bar 4l performs several functions, including
holding the tubes in fixed interrelation, providng
means by which the tubes may be lifted and co
operating with fixed guides hereinafter described, 50
for holding the tubes in proper alignment during
reciprocation. This arrangement is conveniently

is carried bythe back 20. Guides 45 and 52 are
35 opposite and spaced apart slightly in excess of
the diameter of the periphery of the rims of the
cups and the guides V53 and 54 are similarly spaced
when the device is closed so that in closed posi-`
tion of the device the four guides form a run
40 way in which the inverted nest of cups may move
freely up and down. Normally the nest of cups
rests on a portion of the plunger assembly as
illustrated at Figs. 3 and 4 and as hereinafter
