l s claims. (ci. 312-39) This invention relates to vending machines, and more particularly to improvements in coin operated ticket vending machines. f
vAn object of the invention is to provide a coin operated ticket vending machine adapted to feed a ticket web to a point where the end ticket thereof is caused to protrude from the machine in a position where it may be torn free of the web by the vendee, with said machine embodying means insuring that but one ticket may be procured by a vendee for a single coin inserted in the machine. A
A further object of the invention is to provide a highly etlcient and economical coin operated ticket vending machine. i
These and other objects and advantages ofthe inventionf willbe apparent from" the following description taken in conjunction with the drawings forming part of this specication, and in which:
VFigure 1 is a view inside elevation 'of theoperating mechanism of the vending machine before coin operation of the machine, i. e., with the coin slide in the outermost position;
Figure 2 is a view similar to that of Figure l, the side wall of the machine housing being similarly removed, but showing the elements of the vending machine mechanism in their operating position when the coin slide is in its vinnermost position;
Figure 3 is a top plan View of the vending machine mechanism in the operating condition corresponding Vto that of Figure l, with the top of the machine housing being removed for this purpose;
Figure 4 is a detail view of the operating mechanism of the machine taken along lines 4-4 of Figure 3;
Figure 5 is a detail view taken along line 5-5 of Figure 3;
Figure 6 is a detail view taken along Figure 3; n
Figure 7 is a detail view similar to Figure 5 with the parts of the machine shown in a diierent position; and
Figure 8V is a view in section taken along lines 8-8 of Figure 3.
Referring to the drawings, the vending machine is provided with a housing indicated generally at 16 having a front wall 12 and abottom wall 14 secured to a mounting post 16. A pair of spaced carrier plates V18 and 20 secured together by spacer bars 22 are supported within the housing, as by bolts 24 extending through spacer bars 22 and insecured relation therewith. p Journalled for rotation in carrier plates 18 and 28 is a shaft 26 having secured thereto in spaced relation wheels 28 and Sil, each of which is provided on its periphery with a plurality of spaced teeth 32 adapted to be engaged with spaced marginal apertures 34'in a ticket web 36 having transversely extending perforations 38 dening individual tickets.
As is indicated in Figuresv 1 and 2 the ticket web 36 is carried freely on the bottom wall 14 of the housing, with the interconnected tickets being arranged in alterlines 6 6 ef nately disposed stacked relation. As the toothed wheels 28 and 30 are rotated in a clockwise direction, the ticket web is moved over an arcuate baile plate 40 and beneath a plate 42 to protrude from a ticket dispensing slot 44 formed in the front wall 12 ofthe housing. Bale plate 40 is secured to rod 46 carried between plates 18 and 20 and is secured at. itsfupper and forward end to plates 18 and 2i) by suitable means, not shown. Plate 42 is connected by hinge 48 to the upper edge of plate 20, and the opposite end of said plate is retained against the upper edge of plate 18 by a spring clamp 50 secured to the outer face of plate 13. Forced ilexure Vof spring 50 to bring it out of engagement with pivotally mounted plate 42 enables the plate to be pivoted upwardly about the hinged joint 48 so that the apertures 34 of the ticket web may be engaged with teeth 32 of wheels 28 and 30. Baie plate 40 and plate 42 areprovided with aligned slots through which the teeth 32 of the wheels 28 and 38 extend. v
The coin slide actuated mechanism hereinafter described is adapted to positively drive wheels 28 and 30 for a predetermined distance in a clockwise direction for each operation of the mechanism to cause a single ticket section of ticket web 36 to protrude through slot 44, as indicated at 52 in Figure 2, and the control mechanism embodies means rendering the machine tamper-proof in the sense that under no conditions of operation of the mechanism can more than one ticket section percoin be obtained by the vendee, or operator of the machine.`
The driving mechanism for wheels 28 and 30 com prises a lever 54 pivotally mounted on stubshaft 56 which is carried by plate 18, said lever 54 being pro` vided .at one end with a toothed sector 58 which is in mesh with gear wheel 64) sleeved on shaft 26, and being provided at its other end with a depending arm 62 normally held against stop member 64 extending outwardly from plate 18 by a spring 66 connected at one end to` arm 62 and connected at its other end to pin 68 carried by plate 18. Fixedly secured to the outer face of gear'f wheel 60 is an arm 70 which has pivotally secured to the outer end thereof by pin 72 a pawl 74. A ratchet wheel 76 having a plurality of spaced teeth 78 is Iixedly secured to shaft 26, as by key`80, in alignment with pawl 74.
A coin slide 82 slideably disposed within carrier member 84, having integral therewith an escutcheon plate 86 secured to wall 12 of the housing, serves as the control element for the operating mechanism. As the coin slide 82 is moved from its outermost position, as indicatedlin Figure l, to itsV innermost position, as indicated in Fig# ure 2, the innerV end of the slide engages arm 62 of lever 54 and forces said arm outwardly away from the stop member 64 to load the spring 66 and pivotthe toothed t sector 58 downwardly. This movement of the toothed sector in engagement with gear wheel 60 rotates the gear wheel in a counterclockwisev direction to Amove arm and pawl 74 to the position shown in Figure 2 where the pawl is engaged in driving relation with a tooth 78 of ratchet wheel 76.
In the absence of further control elements, it will bel clear that if the manual force applied to the coin slide 82 t were released when the coin slide is in its innermost position, the spring 66 would return arm 62 into engagement with stop 64 and thus cause counterclockwise'rotation i of lever 54 and its toothed sector 58 to drive gear wheel 60, arm 70, pawl 74 and ratchet wheel 76 in a clockwise direction to impart similar movement to shaft 26 and ticket web drive wheels 28 and 30. Means are provided, however, to delay the operation of the mechanism until the coin slide 82 has been moved `outwardly a predeter` mined distance, said means comprising a ratchet wheel 88 ixedly secured to shaft 26, as by key 90, and a trigger i lever 92 pivotally mounted on pin 94 carried by plate 18.

' thereto;`V When the coin slide has been moved to 'its innermost position, as indicated in Figure 2, to cause the pawl 74 to be moved to its driving position, initial return movement of the slide will cause lever arm 54 and its toothed.V sector SV to be moved a slight degree in a counterclockwise direction under the influence of spring The mechanism further` embodies anti-rotation means for the shaft 2 6 to prevent any reverse, or friction-induced, rotation of the same while gear wheel 60 is being rotated on the shaft to bring. pawl .74 into position for driving ratchet wheel 76. The anti-reverse rotation means ,comprises a lever Yarrn 112 pivotally'mounted on pin 114 carried by plate 18 and having its free end urged by spring means 116, connected at one end to lever 112 andrat the other end to plate 18, into engagement with 66 to drive shaft 26 for a slight distance in a clockwise direction toV cause tooth 102 of Wheel S8 to be brought into engagement with dog '96.- After limited movement of'shaft-26,'further'movement is prevented by 'the trigger lever 92 until the coin slide is thereafter returned to a position in which a laterally extending striker plate 104 carried by the' slide engages extension 9S of lever 92 toV pivot lever 92 in a counterclockwise direction and thereby trigger the ticket dispensing mechanism i'n the manner described.
lt will be appreciated that Vwith the mechanism thus far described it would be possible for a vendee to obtain any number of tickets he desired for the single coin used to operate the mechanism so as to extend one ticket ofthe web through the slot 44. Thereafter, the striker plate 104 of the coin slide 82 could be maintained in engagement with arm 98 of lever 92 to maintain dog 96 out of the'rpath of teeth 102 of the ratchet wheelV 88; The ticket web could then be' freely drawn through slot 44. In' order to prevent this, locking means, hereinafter described, are provided to positively limit the tickets dispensed from the machine to one ticket per operating .coin used; v
This one ticket limit means comprises a lever 106 pivotally mounted on pin 94v and urged byl spring 100 in a counterclockwise direction to engage ratchet wheel 8S. 'When dog 96 of lever 92 is out'of engagement withV wheel 88, a hook 108 at the end of leverV arm 106 engages a'. toothv 102 of wheel 88 to prevent ticket delivery movement of shaft 26. After a coin has been deposited in the slide 82 andthe slide is moved inwardly toward the innermost position shownin Figure 2, arm 106 is pivotedinY a clockwise direction by striker plate 104 to move the hooked end 108 of the lever arm out of the path of'teeth Y102v of wheel 83'. The angular relation` of arm' 62 toV coin slide 82 is such in relation to the angular position of lever arm` 106 with respect to coin slide 82,
when the coin kslide is in theinnermost position of Figure 2, that the initial return movement of slide 82' to allow the slight rotation' of shaft 26 to bring a tooth 102 of wheell 88- into engagement with dog 96 of lever arm 92 Atakes'place'before the hooked end 108 of lever arm 106 is moved by spring 100 into the path of the adjacent tooth 102, and thus when a tooth 102 contacts dog 96, the tooth 102 which is adjacent hooked end 108 hasimovedfp'ast this hooked end, as indicated in Figure 7. Thus, when arm 106 has been pivoted in a counterclockwise direction to bring its'hooke'd end into engagement'with wheel S8, thehooked end 108 is in position toenableV a Vsingle ticket operation of wheel 88, butto prevent' free hub 118 of ratchet wheel 88. f Pins 120 carried by ratchet wheel 88 adjacent the teeth1 102 thereof are so arranged `that one of them engages the end of lever 112 when the ratchet wheel is in the positiongof Figures l, 2 and 5. This engagement between apin 120 andthe end of lever 112 prevents reverse rotation of wheel '88 and shaft 26 while lever arm 54 is being pivoted in a clockwise direction to rotate gear in a counterclockwise direction. When the mechanism is triggered by counterclockwise rotation of lever 92, lever arm 112 is pivoted upwardly by movement therepast-of the pin 120 next in order, and, at the same time that arm 62 strikes stop 64 and the hooked end 108 of lever arrn 106 engages a tooth 102 of wheel.88, the lever arm 112 drops behind the pin 120 associated therewith in anti-reverse rotation position. From the foregoing, it will be seen that I have provided a coin operated ticket dispensing mechanism well adapted for the attainment of the objects hereinabove set forth, andl While a preferred embodiment of the invention has been shown and described it is to be understood that all substantial equivalents of said embodiment are within the scope of the invention.
