Although this machine may be used for dispensing any desired kind of ticket, it is particularly designed for parking tickets, and it is, for the sake of convenience, described herein in connection with this type of ticket. Parking ticket vending machines are employed on parking lots in order to avoid the necessity of keeping full-time employees on the lot. A person entering the parking lot deposits the required coin or coins in the vending machine and gets a parking ticket, which is left in his vehicle where it can be seen to indicate that he has paid the parking fee. A person making periodic checks on the lot can see whethereach vehicle has a parking ticket therein.

The prior art includes a number of machines for dispensing parking tickets. However, most of theseare comparatively complicated andtl'ierefore quite expen sive. Some of the simple? machines have the problem that a person if he can insert a flat instrument through a dispensing slot can grip a ticket and pull it out without paying the fee.

A vending machine according to the present invention is of comparatively simple construction, and it includes means for preventing a person from pulling out the next ticket in line for dispensing bymeans of an instrument inserted into thevending'slot. It also includes means for preventing aperson from inserting the required coins and then getting out more than one ticket.

The presentmachine is such that when the required coins are inserted into the coin slide, the latter is shoved inwardly as far as possible to cock the machine. When the slide is moved outwardly towards its normal position,.atieket is moved out of thedispensing slot. If the slide is moved outwardly far enough to enable the next ticket to be drawn out of the machine, the latter cannot be cocked again until the propercoins are inserted .into the slide.

A ticket vending machine according to the present invention comprises a:freely-mounted dispensing shaft having sprocket means thereon for engaging tickets and sequentially moving these, upon rotation of the shaft in a dispensing direction, operating means for intermittently engaging and rotating the shaft, each rotation of the shaft being sufficient to dispense one ticket, latching means for releasably engaging the shaft if the latter is rotated in the dispensing direction by a pull on FIG. 6 is a vertical fragmentary section taken on the line 66 of FIG. 2,

FIGS. 7 and 8 are sections taken on the line 7-7 of FIG. 2 showing inside elevation an index or ratchet I disc in two different positions, the background elements being omitted,

FIG. 9 isa section taken on the line 9-9 of FIG. 2 showing in side elevation only, a -control arm and associated cam in the normal positions thereof,

FIG. 10 is a view similar to FIG. 9 showing the arm and cam in different positions, and

FIG. 11 is a sectional view taken substantially on the through. A fixed flap 18 is secured atan upper end to the outer surface of plate 12 and extending downwardly over but spaced outwardly from slot 15 to prevent direct access to said slot. Ticket web 17 rests on a tray 20 located below the vending mechanism but within the cabinet or casing thereof. The tickets are connected end to end and are alternately folded in a stack on the tray. Theticketsof web 17 have perforations 21 adjacent and extending along opposite edge thereof. A pair of spaced-apartwalls 22 and 23 are secured to and extend inwardly from front plate 12. Web 17 extends upwardly from tray 20 between a pair of closely spaced guide plates 28 and 29 which are curved at 30 arid'extend towards slots 15. ,Upper plate 28 has When it isoperated,the device stamps the ticket ready to be dispensed. I

the ticket to prevent sufficient movement to dispense v the ticket, and releasing means operated by said operating means to release the shaft to permit the rotation by said operating means.

A preferred form of vending machine in accordance with this invention is illustrated in the accompanying drawings, in which FIG. 1 is a side elevation of the ticket vending machine,

FIG. 2 is a horizontal section taken on the line 2-2 of FIG. 1,

FIG. 3 is a view of the inner end of the machine,

FIG. 4 is a horizontal section taken on the line 4-4 of FIG. 1, showing the operating slide in its outer or inoperative position,

, FIG. 5 is a view similar to FIG. 4, but with the operating slide in its inner or operating position,

A dispensing shaft 39 is freely mounted in suitable bearings in support plates 22 and 23, and extends be yond plate 23 to another vertical wall or support plate 40 mounted on and extending inwardly fromface plate 12. A pair of sprockets 43 are fixedly mounted onshaft 39 and project upwardly through apair of elongated openings 44 in upper guide plate 28, and are positioned to engage the perforations 21 0f the ticket web 17 as the latter passes between guide plates 28 and 29. Rotation of shaft 39 and sprockets 44 moves the ticket web to shift a ticket 16 out of the machine through slot 15.

Operating means for the machine includes a standard coin release mechanism 48 mounted on face plate 12 spaced below shaft 39. The coin release mechanism has a slide 49 with one or more coin-receiving holes 50 therein. Slide 49 has a handle 52 at itsouter end. Mechanism 48 doesnot require description herein since it is standard and does not form part of the present invention, but it such that when the required coins are inserted in holes 50, slide 49 can be moved inwardly, otherwise said slide cannot be shifted inwardly.

An operating slide 55 is secured to or forms part of coin slide 49 and moves with the latter. Slide 55 forms part of operating means for machine and is connected, as described below, to a shaft drive linkage including a pull bar or arm 58, rocker arm 60, and an index or ratchet disc 62 secured on the shaft 39.

Pull bar 58 has an elongated slot 65 near its lower end into which a pin or bolt 66 slidably extends from an upright standard 67 which is fixed to and projects upwardly from operating slide 55. The upper end of bar 58 has a pin or bolt 70 which extends laterally therefrom into a slot 71 in the upper end of rocket arm 60, said arm being freely mounted on shaft 39 substantially midway between the ends of the arm. A spring 74 freely surrounds shaft 39 and is connected at one end to support plate 40 and at its opposite end to rocker arm 60, this spring biasing the arm in a clockwise direction against a stop 75 mounted on plate 12.

Disc 62 has ratchet teeth 76a, 76b and 76c on a face thereof, each of these teeth having an incline 77 leading up to a shoulder 78 which extends substantially normally to the adjacent face of the disc, see FIGS. 7 and 8. A spring-loaded plunger 80 is carried by rocker arm 60 near its lower end, and extends towards disc 62 to engage the face thereof from which teeth 76 project. FIG. 7 shows position of plunger 80 relative to the ratchet teeth of disc 62 when the machine is in the atrest position, while FIG. 8 shows the disc after it has been rotated a little during cocking of the mechanism and the new position of the plunger.

A micro-switch 84 is mounted on support plate 23 and has a depending operating lever 85 which is normally in the switch-open position. Switch 84 is electrically connected so that when it is closed, stamping device 36 is operated to stamp the date and time on the ticket between guide plates 28 and 29 and which is the next one to be dispensed.

A rocker 88 is mounted on a shaft 89 and hangs downwardly therefrom, said rocker having a foot 90 which is positioned to engage switch lever 85 when the lower end of said rocker is swung inwardly of machine 10. A spring 91 is connected to foot 90 and extends upwardly therefrom and has its opposite end connected to an extension 92 which projects inwardly from the inner end of operating slide 55. When the slide is in its normal inoperative position, spring 91 is substantially vertical and retains rocker 88 in an inclined position, extending towards face plate 12, as shown in FIG. 1. When slide 55 is moved inwardly to shift the upper end of spring 91 inwardly across a toggle line between the lower end of the spring and shaft 89, rocker 88 is suddenly swung inwardly to move lever 85 and operate switch 84. When this takes place, stamping device 36 stamps a ticket waiting to be dispensed. When slide 55 is moved outwardly again, rocker 88 is swung in the same direction to permit switchlever 85 to move to open the switch.

When the required coins are inserted in holes 50 of coin slide 49, the latter and operating slide 55 can be moved inwardly of machine 10. This swings the lower end of pull bar 58 inwardly and draws this bar in the same direction to swing rocker arm 60 about shaft 39 into the position shown in broken line in FIG. 6. This shifts plunger 80 across the face of disc 62 ad up over tooth 76c into the position shown in FIG. 8. This cocks the machine. At the same time, the movement of the slide 55 causes stamping device 36 to stamp the ticket ready to be dispensed, as described above, When the coin slide is drawn outwardly, and this action is assisted by a spring 95 which has one end connecteddo face plate 12 and its opposite end connected to a bolt 96 projecting upwardly from the inner end of operating slide 55, bar 58 is shifted outwardly and causes rocker arm 60 to swing back to its normal position, spring 74 assisting this action. When this takes place, plunger 80 engages disc tooth 76c to rotate disc 62, and as this disc is fixed to shaft 39, the shaft rotates with it. This rotation turns sprockets 44 to move the ticket 16 engaged thereby out through dispensing slot 15, at which time it can be torn off web 17.

With the arrangement described so far, a person could insert an instrument through slot 15 to grasp the next ticket in line for dispensing and pulling said ticket out of the machine, but suitable latching means is provided for preventing this. This latching means includes a Y-shaped arin 102, cam 105, and stop member 108.

Arm 102 is swingably mounted on a pin 109 projecting laterally from support plate 23, and consists of a downwardly-projecting lever 110 and two upwardlyprojecting members 111 and 112. A spring 113 normally biases lever 1100f arm 102 in an anti-clockwise direction towards face plate 12 into a normal at-rest position, as shown in FIGS. 1 and 9. The upper members 111 and 112 of Y-arm 102 have pins 115 and 116, respectively, projecting laterally therefrom into the path of cam 105. Another pin 117 projects laterally from arm 102 just below pin 116.

Cam 105 is fixedly mounted on shaft 39 to rotate therewith. This cam has three projections 1200, 120b and 1200 radiating therefrom and spaced l20apart around the cam circumference. These projections extend into the general plane or path of pins 1 15, 116 and 117.

Stop member 108 consists of a bent arm pivotally mounted in a bracket projecting from side plate 23,, see FIGS. 2, 4 and 5. The stop member arm has a stop end 126 and an opposite inclined end 127 against which an end of a leaf spring 128 bears. This leaf spring is mounted on wall 23 at 129, and it presses inclined end 127 of the stop arm outwardly from the wall so as to normally maintain stop end 126 against said wall, at which time it is in the path of the lower end or lever 110 of arm 102.

The latching means of apparatus 10 normally prevents rotation of shaft 39, and suitable releasing means is provided to disengage the latching means and thereby permit rotation of the shaft. This releasing means includes a release plate mounted on the upper surface of operating slide 55 and extending longitudinally of said slide, see FIGS. 4 and 5. This plate has a finger I36 projecting laterally therefrom so that it can engage arm 102 when the slide is moved inwardly sufficiently to cock the dispensing means. A pin 137 projects upwardly from release plate 135 near the end thereof remote from finger 136, this pin being in line with the inclined end 127 of stop member 108.

FIG. 9 shows arm 102 retained in its normal position by spring 113, at which time pin 115 is against projection 120a of cam 105 so that the latter cannot be rotated. This prevents rotation of shaft 39, thereby preventing the drawing of a ticket 16 through dispensing slot 15. When coin slide 49 is moved inwardly with the coins in holes 50, operating slide 55 and release plate 135 move in the same direction. When pin 137 engages the inclined end 127 of stop member 108, this inclined end is swung inwardly against the bias of spring 128 to shift stop end 126 out of the path of lever 110 of arm 102 so that the latter is free to move to the position shown in FIG. 10. This shifts pin 115 out of the path of cam projection 120a so that the cam and shaft 39 can now be rotated. At the same time, pin 116 engages projection 120:: to rotate cam 105 and therefore shaft 39 about 40 to cause the end of the ticket to project from slot 15. This action rotates disc 62 to the position shown in FIG. 8. However, pin 117 of arm 102 being in line with projection 12% of the cam prevents the latter projection from reaching and moving pin 116. When the coin slide is drawn outwardly or moves outwardly under the action of spring 95, spring 113 returns arm 102 to its normal position, at which time pin 115 has passed cam projection 120a and is in line with projection 120C to prevent further rotation of the shaft so that only one ticket is dispensed at a time. As arm 102 returned to its normal position, pins 116 and 117 were shifted out of the path of cam projection 120b to permit the rotation of the cam and the shaft, thereby causing the rest of the ticket to be moved through slot 15. However, pins 116 and 117 are not clear of projection 12% until arm 102 has swung outwardly sufficiently to clear stop 126 to allow spring 128 to shift thisstop back into the path of arm 102. This outward movement of the slide is so far that release mechanism 48 prevents it from being moved inwardly again until additional coins are inserted into the coin slidekWhen pin 115 returns to its normal position it engages the next cam projection 120a. If projection 1205 had been allowed to swing around to engage the back of projection 120e, pin 115, in engaging the front of said projection 1200, would rotate cam 105 and shaft 39 backwards a little, and this could cause trouble with the ticket web 17.

Ha person were able to grip the ticket lying between guide plates 28 and 29 and attempted to draw it out through slot 15, cam projection 120a bearing against pin 115 would cause arm 102 to start to swing inwardly, but it would only'move until itengages stop end 126 of stop member 108. This permits only a small movement of the ticket which is not sufficient to enable the whole ticket to be drawn out of the machine.
