‘
The mechanism for holding and covering the 40
bottles to be vended is essentially a chain con
veyor and consists of a plurality of receptacles 98,
each one of which comprises bottle holding cups
99 and I00, formed of a single stamping. The
vertical sides of the bottle holding cups are cut 45
away as at I04, in order to enable free circula
tion of the cooling water through the bottle cups
and also to reduce the resistance of the cooling
water against the travel of the conveyor through
such cooling water.
50
The chain conveyor carrying the receptacles 99
and M0 is driven by a sprocket, not shown,
mounted on hollow shaft I23, which is releasably
or detachably keyed at its upper end by‘means of
a key I125 to a second shaft I25 rotatably mount 55
2
2,077,430
ed in a bearing I21. The key I25 engages a slot
I28 in the shaft I26 in normal operating position,
and permits relative vertical movement of the
shafts I23 and I26 while still coupled for rotation,
5 as set forth later.
As best shown in Fig. 3, the said shaft I26 has
integrally formed therewith an annular plate or
disc member I29 depending from which are a
series of cams I30.- Mounted upon said member
10 I29 is a gear I3I having external teeth I32 which
controlled mechanism to» its original position and
holds the clutch mechanism in idling position.
The aforesaid cams I 30 are timed to engage
an anti-friction roller I5I carried by a shaft I52
slidably mounted within a bearing I53 and hav
ing a vertical slot I54 at its lower end detachably
engaging a transverse pin I55 mounted on a stub
shaft I56 normally held in extreme vertical po
sition in a bearing I51 by means of a coil spring
I58 compressed between the bearing I51 and an 10
annular member I58’ carried by the shaft I56.
'Said'shaft I56 is pivotally connected at I59
in turn mesh with a gear I33 carried by a shaft
I34 mounted in a suitable bracket I35 attached
by supports I36 to the interior wall of a dome Figure 5, to a bottle-ejecting yoke I60 pivotally
or housing I31 and in an adjustable bearing I35’, , mounted at I6I and I62, such yoke carrying a
15 supported also by said housing I31. Said shaft pair of ?ngers I63 located so that during the
I34 carries a bevel gear I38 which is normally latter. part of their upward travel they are di
rectly in line [with the slots I05 in the bottom
adapted to rotate freely about or loose on such
shaft I34, but which can be, through the medium of either cup 99 or I00 as the case may be.
Directly above the bottle to be vended by the
of a clutch mechanism I39, made to drive the’
apparatus, the cover 42 has a discharge open 20
20 shaft I34. The said gear I38 meshes with a bevel
ing I64 protected by an annular metal casing
gear I39’ mounted upon and rotatable with a
shaft I40‘ which extends through to the front or ring I65 which carries a disc I66 of sheet
rubber or other suitable material, having a small
of the casing I31 where such shaft I40 is pro
centralopening I61 around which the disc I66
vided with an operating handle MI.
25
The front of the casing I31 is provided with
a coin slot I42 adapted for the insertion of a
coin of the proper denomination for the price
of the article to be vended. Insertion of a coin
in such slot I 42 followed by manual turning of
30 the handle MI in a clockwise direction, operates
conventional coin-controlled mechanism which
forms no portion'of the present invention except
as described hereinafter. A coin controlled
mechanism which may be employed, is disclosed
35 in Letters Patent No. 2,015,351, issued to me on
September 24, 1935.
The operation just described causes the coin
controlled mechanism to function and a continu
ous movement of the handle I‘lI moves or causes
40 a detent member I43 to swing against the tens
sion of a spring I44 to release contact with and
move out of the path of an extension I45 of
a pawl I46 to trip the pawl against the tension
of a spring I41.
45 Said pawl I46 serves as a coupling or clutch
means to control operation of the machine by
the handle I4I. Such pawl I46 is pivotally
mounted by a shaft I50 to the free end of a
bracket member I59’ which is ?xed to shaft I34.
50 Secured to the lower end of said shaft I50 is
an abutment I49’ which in operative position is
engaged by one of a series of studs I49 carried
on the upper face of the bevel gear I 38, when
detent I43 has disengaged pawl I46.
55 An extension I48 is provided on pawl I46 and
engages a stop I48" on bracket member I50’ to
ensure engagement of abutment I49’ and one
of the studs I497 through arcuate alinement.
When the various parts are in their operative
60 positions as shown in Fig. 6, shaft I40 and gear
I39’ are rotated by means of handle MI and in
turn rotate gear I38. ,One of the studs I49 en
gages the abutment I49’, and rotates the entire
clutch mechanism, through the medium of
.65 bracket I 50", thereby rotating shaft I34 and
shaft I26 through gears I3I andI33.
When the coin mechanism is at rest or in in
operative position, the member I43 contacts ex
tension I 45 of pawl I46 and holds abutment I48’
is slit radially to form V-shaped segments which 25
taper toward the opening I61.
Below the ring I65 is a guard member desig
nated as a whole by the numeral I69 and com
prising a depending annular skirt I10 provided
with a pair of slots or openings I1I in line with 30
the transverse path of travel of the bottles I12
on the front stretch of the conveyor as they
travel toward the discharge opening.
The purpose of this member I69 is to prevent
the unauthorized removal of a bottle through 35
the discharge opening by insertion of the ?ngers
through such discharge opening prior to the dis
charging operation of the bottle as shown in
dotted lines in Fig. 10.
To prevent deposit of a coin when there are
no bottles contained within the machine, means
are provided as follows: A bar I13 extends par
allel with the front line of bottles nearest the
point of discharge and is pivotally mounted on
a horizontal axis to guard I10 as at I14, extend
ing between said guard and a guide I15’ carried
by said guard and is provided adjacent the dis
charge opening I64, with a horizontally dis
posed leaf I15 of a length to engage the tops of
at least two of the oncoming bottles which main 50
tains the bar I13 normally horizontal. In the
absence of a bottle beneath leaf I15, the right
hand end of bar I13 lowers, Fig. 5, and the left
hand end of such bar I13 raises, also raising a
bar I16, due to‘ the contraction of a spring I11, 55
attached to bar I16 and casing I 31, member I16
carrying a link I18, see Fig. 4.
Bar I16 is pivotally connected at I16’ to a link
I18, journaled at I18’ in a bracket I18" on cas
ing I31 as shown in Fig. 6, thus enabling a ter 60
minal I19 of said link, when the machine is
empty, to enter an opening I80’ in the coin-con
trolled mechanism and intercept movement of a
horizontally movable slide I19’ of that mecha
nism to the left in Fig. 6, which movement is
essential to enable slide I19’ to uncover the coin
deposit slot I42, the speci?c construction of such
coin-controlled mechanism otherwise formingno
part of the present ‘invention. Thus the raising
‘and lowering of bar I16 respectively rocks link 70
I18 into and out of opening I80’ and the path
of return movement of slidev I19’. Broadly ex
pressed, bar I 13 lowers at its right-hand end, Fig.
70 out of the circle of the studs I49 against the
action of spring I41, so that if handle MI is
turned, gear I38 will rotateidly on shaft I43.
Upon completion of the complete revolution of
gear I38, cam I45 again engages member I43
,5, when the machine is empty as there are no
75 which has returned by operation ,of the coin
bottles beneath leaf I15 to keep it raised and ter

turn of the slide I19’, and hence prevents un
covering of coin slot I42 by that slide.

so that its terminal I19 enters opening I80’ and
intercepts the return of slide I19’, thus prevent
ing such slide from uncovering the coin slot I42,
In the absence of a coin in the slot I42, the
handle I4I may be revolved freely without oper
ating the vending mechanism, as turning of the
handle I4I will rotate shaft I40 and the gear
I39 carried thereby and consequently the bevel
gear I38 only. Said bevel gear I38 moves freely
about the shaft I34 because the abutment I49’ is
out of the path of movement of the studs I49
or the like, and mechanism under control of the
and consequently no clutching action takes place.
bottle being vended operable automatically to
Upon the insertion of a coin in slot I42 and a
subsequent rotation of handle I4I, the coin-con
15 trolled mechanism operates and releases or re
tracts detent member I43 from contact with pawl
element I45, whereupon spring I41 moves the
clutch pawl I46 toward shaft I34 thereby placing
abutment I49’ in the same circle with the studs
2 0 I49 on gear I39. Continued rotation of the handle
I 4| causes the adjacent stud I49 to engage said
abutment I49’ which couples gear I38 to shaft
I34 through bracket I50’. As shaft I34 revolves,
it drives through the medium of gear I33, the gear
2 5 I3I enmeshed therewith which carries with it the
disc I29 imparting rotation also to shafts I26
and I23 which imparts motion to the entire con
veyor.
Upon the start of an operation there is no
3 0 bottle in line with discharge opening I64 and the
until the machine has been re?lled with bottles.
Various changes may be resorted to within the
spirit and scope of the invention as de?ned by
the following claims.
I claim:
