SINGLE-VEND DISPENSING MACHINE BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a single vend periodical dispensing mechanism for dispensing newspapers, magazines, or the like, in such a manner that only a single newspaper or periodical is dispensed from the dispensing mechanism during each dispensing cycle when the proper coins are inserted into the coin operated mechanism.
2. Description of the Prior Art A number of newspaper racks and the like have been developed to provide a means of vending such items without the necessity of an attendant.
The earliest type of rack comprises simple support type racks or structures. Although these racks were extremely inexpensive to manufacture and maintain, the items were generally exposed to the elements and easily pilfered without payment for the items.
The next generation of racks generally comprised enclosed coin operated vending machines. Since the items were commonly enclosed within a cabinet, they were protected from the elements. However, access into the cabinet during the dispensing cycle permitted removal of all the remaining items. Thus, even these coin operated vending machines were subject to pilfermg.
More recently, various attempts have been made to develop single vend coin operated vending machines to permit dispensing only a single item during each operating cycle. These single vend machines may be characterized as either vertical or horizontal feed type devices. Unfortunately, the horizontal feed devices comprise complicated feed and actuating mechanisms which are expensive to both manufacture and maintain. On the other hand, the weight of the vertical stack of items in the vertical type feed device commonly necessitates the use of elaborate bias and release mechanisms which attendant costs of manufacture and assembly.
Thus, there is an obvious need for an inexpensive, highly reliable single vend newspaper/periodical dispensing machine.
SUMMARY OF THE INVENTION This invention relates to a single vend periodical dispensing mechanism. More specifically, the dispensing mechanism comprises a support frame having a cabinet housing attached thereto to house a vertical stack of newspapers or other periodicals to be dispensed. A dispensing access door and loading access door are pivotally attached to the front and top of the cabinet housing respectively, as more fully described hereinafter.
A periodical support means is movably mounted on the support frame to position the periodicals in the dispensing position. The periodical support means comprises a substantially horizontal elevator platform means to support the stack of periodicals, elevator lift means coupled to support-the frame to operatively position the stack of periodicals relative to a dispensing opening for dispensing and elevator release means to permit dispensing of the periodicals.
The dispensing machine includes a thickness gauge means arranged relative to the support frame to vary the size of the dispensing opening to permit withdrawal of a single periodical during each dispensing cycle. The dispensing machine also includes a dispensing control means including locking means to limit withdrawal of a single periodical during each cycle.
In operation, the periodical support means acting on the stack of newspapers or periodicals within the cabinet housing forces the uppermost periodical in the stack into dispensing alignment relative to the dispensing opening. When the dispensing access door is swung open, the top newspaper or periodical in the cabinet is released for dispensing or removal by the elevator release means. The elevator release means relieves the tension on the stack of periodicals to prevent excessive pressure on the periodical in dispensing position to permit free and easy withdrawal from the mechanism while at the same time exerting sufficient pressure to always maintain the uppermost periodical in the dispensing position.
When the top newspaper or the like is removed from the cabinet, all remaining newspapers are locked in the cabinet housing by the dispensing control means. Thereafter, a new cycle, starting with the insertion of the proper combination of coins to release the paper dispenser door for the dispensing or withdrawal of additional newspapers, is required.
The invention accordingly comprises the features of construction, combination of elements, and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the invention will be indicated in the claims.

DETAILED DESCRIPTION OF THE PREFERRED I EMBODIMENT As best shown in FIGS. 1 and 4, the present invention comprises a dispensing machine generally indicated as 10 including a support frame 12 and cabinet housing 14 attached thereto. The cabinet housing 14 includes front and rear walls 16 and 18 respectively and side walls 20 and 22 respectively held in fixed position relative to each other by rectangular base 24. Dispensing access door 26 including handle means 28 and door extension 30 is pivotally attached to front wall 16 by hinge 32. Dispensing access door 26 is normally biased to the closed position by closing springs (not shown) such that door extension 30 engages front wall 16 (FIG. 1). Release actuating means comprising member 34 is attached to dispensing access door 26. A transparent display window 36.may be formed on front wall 16. Also formed in front wall 16 are coin receiving means 38, coin return actuator and coin return receiver 42. Loading access door 44 comprising a substantially flat horizontal rear portion 46 and enlarged forward portion 48 to house a dispensing control means, to be more fully described hereinafter, is pivotally attached to upper portion of rear wall 18 by hinges 50 (FIG. 3). Loading access door lock 52 is also housed within enlarged forward portion 48 to lock loading access door 44 closed. Guide opening 54 and transparent newspaper display window 56, as more fully described hereinafter, are formed in loading access door 44. A limit means comprising a flexible chain 58 is interconnected between loading access door 44 and side wall 20 (FIG. 4) to limit the movement of door 44 relative to cabinet housing 14.
As best shown in FIGS. 4 and 5, the support frame 12 comprises upper rectangular member 60 and base 24 held in fixed position relative to each other by forward and rear side panels 62 and 64 disposed on either side of cabinet housing 14.
FIG. 2 is a front view of the dispenser cabinet with front wall 16 removed to show the thickness control means similar to that described in my patent application Ser. No. 3,623 filed l-l9-l970.
The thickness control means includes a vertically disposed rectangular channel 66 having stiffeners 68 and 70 rigidly secured thereto by. brackets 72. Channel 66 and stiffeners 68 and 70 are rigidly secured to horizontal channel 74 attached to base 24. Rod 70 may be adjusted to overcome inaccuracies encountered in manufacturing, obtaining an even dispensing opening means 76 cooperatively formed between the top of the thickness control means and the bottom of loading access door 44. Since the purchaser manually withdraws the periodical through this opening 76 it is important that this opening 76 be adjustable to a height that will permit the withdrawal of only one periodical at a time.
The thickness control means also includes a thickness actuating assembly comprising horizontal channel 74, vertical angle section 76 and vertical angle section 78. One end of walking beam 80 is pivotally attached to vertical angle section 76 by fastener 82. Walking beam 80 is also pivotally-connected to channel 66 by fastener 84. The opposite end of walking beam 80 is held against vertical angle section 78 by guide strap 86. The upper and lower ends of strap 86 are secured to vertical angle section 78 by fastners 88. Space bushings (not shown) located between vertical angle section 78 and strap 86, provide space for the accurate travel of walking beam 80. The walking beam 80 is shown in phantom as 80a in the locked position. Index plate 90 is pivotally mounted at the lower end of vertical angle section 78 by fastener 92 while the top end is held in position by retainer strap 94 secured to vertical angle section 78 by fasteners 96. Spacer bushings (not shown) located between vertical angle section 78 and retainer strap 94 provide space for the swinging movement of the top end of index plate 90. Expansion spring 98 has one end secured to tab 100 formed on index plate 90 and the opposite end secured to vertical angle section 78 to swing clockwise away from walking beam 80. Index plate 90 includes a plurality of locking teeth 102 for locking walking beam 80 by cooperative engagement of tongue 10 formed on walking beam 80 between teeth 102 to lock channel 66 in the desired position. Index plate 90 is held in position by member 106, which is swingably mounted to vertical angle section 78. Member 106 is interconnected to a lock means (not shown) by an actuating linkage 108 to move index plate 90 between locked or unlocked position. The lock means may be unlocked by actuating linkage 108 to allow member 106 to move upward away from index plate 90 permitting clockwise movement of index plate 90 to disengage tongue 104 of walking beam 80 from teeth 102 to adjust channel 66. i
To operate the thickness control means so that only one periodical can be withdrawn from dispensing machine at a time, the operator unlocks lock means to free index plate 90, freeing the thickness actuating assembly for adjustment. The operator'then manually pulls the top periodical forward several inches. To adjust the width of the dispensing opening 72 the operator manually raises channel 66 upward until the top end presses against the bottom of the partially pulled out periodical, then locks the entire assembly in position. With the thickness control means in the locked position, the dispensing opening 72 is just wide enough to allow withdrawal of a single periodical.
FIG. 10 is a perspective view of the bottom of loading access door 44 showing a portion of the dispensing control means. As previously described, loading access door 44 comprises enlarged forward portion 48 and horizontal flat rear portion 46'. A pair of substantially rectangular apertures 110 are formed on the bottom 1120f door 44 on opposite sides of guide opening 54. A pair of tripping plates 114 pivotally mounted on shaft 116 are arranged to operatively extend through apertures 110. As more fully described hereinafter, a second pair of substantially rectangular apertures 118 are formed in bottom 112. A pair of locking plates 120 are arranged to operatively extend through apertures 118. The dispensing control means further includes a reset means comprising reset plate 122 interconnected to locking plates 120 by reset plate shaft 124 and aperture 126.
As shown in FIG. 10, the uppermost paper A in the dispensing portion is disposed to engage and actuate the dispensing control means. To operate, paper A is manually withdrawn from cabinet 14 through opening 72 (FIG. 2). Tripping plates 114 normally extend outward through apertures 110 in front of the uppermost paper A. As the paper A is withdrawn, tripping plates are cammed inwardly and out of the path of the paper I A moving locking plates 120 across dispensing opening 72 to prevent removal of additional papers. When the proper coin or combination of coins is inserted in the coin mechanism, dispensing access. door 26 is unlatched, allowing door 26 to be swung open to paper access position. When door 26 is opened, reset plate 124 is actuated causing locking plates 120 to swing from the paper lock-in position across the paper removal opening 72, and come to rest in unlocked position and extend tripping plates 114 to allow authorized removal of a paper from the dispenser machine 10.
As best shown in FIGS. 4 and 5, the periodical support means comprises a substantially horizontal elevator platform means 128, elevator guides 130, elevator guide rails 132, ladder chain 134 and elevator lift springs 136.
As best shown in FIGS. 7 an 8, elevator guides comprise inner'and outer plates 138 and 140 respectively held in substantially parallel relation to each other by connecting rods 142 disposed at each of the four corners. Rotatably mounted on each of the connecting rods 142 is guide roller 144 held in spaced relation to plates 138 and 140 by spacers 146. Inner plate 138 is fixedly attached to elevator platform means 128 by stud 148. An elevator guide rail 132 extends vertically on either side of the frame between base 24 and upper side frame member 60. Guide rails 132 comprise a substantially flat bar 148 with stiffener channels 150 extending the length thereof. The width of bar 148 relative to the horizontal separation of rollers 144 is such that rollers 144 engage opposite sides of bar 148 to guide the vertical movement of the elevator platform means 128. One end of ladder chain 134 is coupled to elevator means by stud 152 and at the opposite end to elevator lift spring 136.
As best shown in FIG. 3, periodical support means further includes idler rollers 154. Elevator lift springs 136 operatively engage idler rollers 154 and are fastened to the frame by interconnecting shaft 158 by fastening means 160.
As best shown in FIGS. 4 through 6, the actuating means comprises actuating linkage 162 and elevator release means generally indicated as 164. The purpose of the elevator release means 164 is to relieve the up ward pressure exerted between the elevator platform means 128 with the periodicals stored thereon and the bottom 112 of door 44 by elevator lift springs 136. Elevator release means 164 comprises ratchet 166, drive sprocket 168 and crank means 170 mounted to frame member 60 by interconnecting shaft 172. A ratchet pawl 174 is mounted on crank means 170 by mounting stud 176 and held in spaced relation thereto by spacer 178. The outer end of mounting stud 176 is operatively coupled to door extension 34 by actuating linkage 162 (FIG. 5). Elevator release means 164 further includes camming plate 180 attached to side panel 64. Camming plate 180 is interconnected to crank means 170, by spring 182 to normally bias elevator release means 164 to the forward most position (FIG. 4) such that pawl 174 engages plate 180 to cam pawl 174 out of engagement with ratchet 166. An idler sprocket 184 similar to drive sprocket 168 is mounted on the opposite end of interconnecting shaft 172 which extends the width of the cabinet 14 (FIG. 9). In addition, a pair of idler sprockets 186 are mounted on opposite sides of upper frame member 60. The outer end of shaft 172 is mounted on bearing 188 (FIG. 6).
Normally, pawl 174 is held out of operative engagement with ratchet 166 by plate 180. To operate, dispensing access door 26 is pivoted open causing linkage 162 to move rearwardly rotating crank means 170 to revolve clockwise about shaft 172. As crank means 170 rotates clockwise, pawl 174 engages ratchet 166 causing shaft 172 to rotate clockwise. As shaft 172 rotates clockwise, drive sprocket 168 rotates pulling ladder chain 134 upward allowing elevator platform means 128 to move downward to relieve the pressure created by elevator shaft springs 136. Since idler sprocket 184 is coupled to shaft 172, the opposite ladder chain 134 is simultaneously drawn upward relieving pressure on the opposite side of elevator platform means 128. As dispensing access door 26 is returned to the normally closed position, pawl 174 is cammed out of engagement with ratchet 166 allowing elevator lift springs 136 to elevate elevator platform means 128 upward to move the upper most periodical A in dispensing position relative to dispensing opening means 72.
To load, the operator opens loading access door 44 and removes unsold periodicals, if any, and reloads the dispensing machine 10 with the current issue by placing the periodicals on the elevator platform means 128. The elevator platform means 128 and the periodical slope thereon, is forced downward as the periodicals are loaded will maintain the desired down position and facilitate the unobstructed loading of additional periodicals.
After loading, the loading access door 44 is closed and locked to prevent unauthorized removal of the periodicals therefrom.
With the dispensing access door 26 opened, the operator adjusts the thickness control means as previously described. Once the dispensing access door 26 is closed, the machine is ready for normal operation.
To operate, the proper selection of coin is inserted into the coin receiving means 38 which permits the opening of dispensing access door 26. As previously described, as the door is opened the actuating means relieves the upward pressure exerted by the elevator lift springs 136 permitting withdrawal of the uppermost periodical. It should be noted that guide aperture 54 permits the insertion of a hand below the enlarged portion 48. As the upper most periodical is withdrawn from the dispensing machine 10 the dispensing control means locks the remaining papers in place as previously described. As the dispensing access door 26 is returned to a normally closed position, all remaining periodicals are locked in the cabinet housing 14. Thereafter, a new cycle starting with the insertion of the proper combination of coins repeats the process.
It will thus be seen that the objects made apparent from the preceding description, are efficiently attained and,-since certain changes may be made in the above construction without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawing, shall be interpreted as illustrative and not in a limiting sense.
