VENDING MACHINE
Benjamin S. Mahaffey, Chicago, Ill.
Application July 25, 1936, Serial No. 92,625
12 Claims.
This invention relates to vending machines.
It has for its general object the provision of
vending apparatus for articles which deteriorate
through the action of air, such, for example, as
5 cigars, nut meats, etc.
One of the objects of the invention is to pro
vide individual receptacles for each sales unit, in
which the article is maintained in a non-oxidiz
ing atmosphere until dispensed. Y
10
-
Another object of the invention is to maintain
the article in individual chambers in a vacuum,
to utilize the vacuum for assisting in holding the
chambers closed in a fluid-tight manner, and for
mechanically breaking the vacuum through the
15: intermediary of an inserted coin for opening the
chamber and discharging its contents.
Since the operating structure is mechanically
useful regardless of the adjunctive use of vacuum,‘
the invention has for another of its objects the
204 provision of a vending machine having the novel
structural characteristics and operative sequences
such as will be disclosed in the following speci?
cation and illustrated in the accompanying draw
ings, in which:
25
Figure 1 is a side section view of a vending
machine, parts being broken away, illustrating
the principle of the present invention;
Figure 2 is a section taken along the line 2—2
of Figure 1;
30
Figure 3 is a section taken along the line 3-3
of Figure 1;
Figure 4 is a vertical section through one of the
receptacles;
Figure 5 is a plan view of one of the receptacles
or holders in a modi?ed form of the invention;
Figure 6 is a section taken along the line 6-45
of Figure 5; and
Figure 7 is a fragmentary section showing the
relation of the supporting ledge to the upper
40 frame only of the lowermost vending unit.
Referring now in detail to the several ?gures
and ?rst adverting to that form illustrated in
Figures 1 to 4, inclusive, the numeral I repre
sents in general a cabinet having a relatively tall
45 stack casing 2 and a base portion 3, which is use
ful for holding the empty receptacles as they are
displaced from the stack in a manner presently
to be described.
Within the stack casing is a stack 4 constituted
50 by a vertical tier of receptacles 5. One of these
receptacles is shown on an enlarged scale in Fig
ure 4 and consists of a body portion 6 de?ning a
chamber ‘I, the lower face of which is open, the
receptacle being provided with a bottom closure
’ 8 preferably hinged as at 9 and fitting in a ?uid
(Cl. 312—94)
tight manner against the lower face of the body
portion 6. To facilitate the sealing function of
the closure a gasket It may be placed between
the cooperating faces of the body portion and
closure.
5 '
The lowermost receptacle H is supported by
ledges E2 on opposite sides and slide like a drawer
upon said ledges. The other receptacles rest one
upon another and upon the lowermost receptacle
l I, the closure 8 of which, excepting that of the low 10
ermost receptacle being supported in closed posi
tion by the receptacle next underlying. In the
event that the receptacles are evacuated, the
pressure of the atmosphere also assists in holding
the closures tightly against the receptacles. It 15.
will be observed from Figure v1 that there is noth
ing to hold the closure 8 of the lowermost recep
tacle closed and so it lies open in an inclined posi
tion determined by its engagement with the stop
M which extends inwardly from the front end of 20
the cabinet. All of the receptacles in the stack
will successively go to the position occupied by
the lowermost receptacle 5 I, the closures when in
inclined positions acting as chutes for discharg
ing the contents of the receptacles which con
tents'issue through the slot I5 into a cup I6, from
which they are gathered in the hand.
-
Coin controlled means is provided for pushing
the lowermost or empty receptacle out of the way
and bringing another receptacle from the stack
into a position in which its contents may be dis
charged.
The coin controlled apparatus illus
trated here consists of a guide I? and a slide I8.
The slide as shown has a downwardly extending
end piece l9’ within the cabinet in a position to
engage with and push the lowermost receptacle
I I. When a coin is inserted in the slot 20 and the
slide is pushed inwardly, the coin presses against
the bulge of the spring l9 forcing it down and
throwing the end 2! below the plane of the slide
l8 and out of engagement with the slide so that
the latter can be freely pushed. When the slide
is pushed in, to its fullest extent, the lowermost
receptacle II takes the position shown in dotted
lines at 22 and then falls empty into the base of
the cabinet. The other receptacles of the stack
are guided for vertical fall by means of vertical
guide rails 23 which terminate about in the plane
of the top face of the lowermost receptacle and
being deprived of the support of the lowermost
receptacle, may descend together until the recep
tacle at the bottom occupies the vacated space,
resting upon the ledges I2. In the event that the
chambers ‘I are to be under vacuum, valve con
trolled ports 24 are provided each closed by a

stood that the detailsof construction as'shown
and described are merely by way of example and
not to be construed as ‘limiting the scopeof the

the vale plate, projects below the plane of: the
bottom of the receptacle in a position to be en
caged by the receptacle next below when the
latter is horizontally displaced so that'the dis
placed receptacle acts .to- open the ,valve of the
