Application January 18, 1947, Serial No. 722,823

The present invention relates to 'a coin controlled dispensing machine particularly designed.

an improved and simplified means for supporting A and serially releasing a plurality of articles, which means is characterized by the fact that each article is supported independently of the others and is free from the effect of the weight of the others.

4 Claims. (Cl. 31235) Another object of the invention is to provide a machine of the type described adapted to contain two or more separate groups of articles and having a simplified manually operated means for selectively discharging an article from any desired group.

Another object of the present invention is to provide improved means for preventing improper operation of the machine.

Other objects and advantages of the invention will become apparent from the following specification, the accompanying drawings and the appended claims.

Figure 9 is a wiring diagram of the machine.

In coin controlled dispensing machines, it is necessary to provide storage for a relatively large number of articles of the same kind in order to reduce the need for frequent recharging of the. machine. In some cases, either due to the weight or the fragile character of the articles dispensed by the machine, it is undesirable to stack the articles one on top of another. If the articles are fragile, such stacking may result in a crush- 2 ingof the articles; if the articles are of substantial weight, it may also make it diflicult to withdraw an article from the. bottom of the stack. These difficulties are overcome, in accordance with the present invention, by suspending the articles in an envelope or sack from a horizontally disposed cantilever screw. Thus, the screw not only acts as the support for the complete charge of articles of the same type, but, upon rotation in a step-by-step manner, discharges the articles one at a time. Since each article hangs. freely in its sack or envelope, there is no danger of injury to the article and no'interference with the discharge of articles from the end of the screw. While the principle embodied in the present invention may be employed to dispense any type. of article which may be enclosed within a sack or envelope, it has peculiar advantage in dispensing phonograph records which are positioned within the usual paper envelopes and, accordingly, the embodiment of the invention selected for illustration comprises a machine adapted to dispense disk phonograph records.

The machine in general comprises a casing I of any suitable material, such as sheet metal, within which is positioned a plurality of-laterally opposed-pairs of vertical supporting posts 2, 3, 4, 5

- graph records,.which records are positioned within envelopes l8. The top portions of the envelopes are provided with apertures I9 of sufficient size to thread over the screw I4. The thread on the screw may be of any desired form but is preferably relatively deep and has a rounded root portion, as best shown in Figure 5. Screw M has a shank portion 20 which is journaled by means of antifriction bearings 2| carried by the housing 9, and a gear 22 is fixed to the shank 20 andpositioned within the housing. Gear 22 meshes with a gear 23 to which is fixed at one side a faceplate 24 which carries one hub of the gear and which closes the countersunk opening 25 formed in the gear. The composite gear made up of the gear element 23 proper and the plate 24 is also journaled by means of antifriction bearings-26 in the housing 9. A circular disk 21 is positioned within the countersunk opening 25 and is provided with a central opening in which 3 is formed a plurality of helically splined teeth adapted to fit the helically splined shaft 28 which projects through the disk 21 and also through the composite gear 23-24. The opening formed in the gear 23-24 is of larger diameter than the outside diameter of the splined member 28, with the result that no direct contact occurs between the splined shaft and the gear. However, the disk 21 is provided with hub portions which are journaled within the gear opening and which serve to hold the splined shaft 28 on the axis of the gear.

The splined shaft 28 is connected at one end to a rod 29 which extends toward the front face of the machine and through a supporting and guiding plate 30, in the manner best shown in Figure 6. The forward end of the rod 29 is connected by means of a pin 3| to a square rod 32, the forward end of which projects throughthe front wall 33 of the casing I and carriage pull knob 34. The rods 29 and 32 and associated splined shaft 29 are normally'held in their inward ported thereon to the right, dropping one enposition by means of a coil spring 35 which bears at one end on the plate 30 and at the other end on the flange 36 of a sleeve 31 positioned on the rod 29. The forward end of the sleeve 31 limits As a result of the above described arrangement, when the knob 34 is pulled outwardly, the splined shaft 28 is reciprocated axially without rotation, thereby causing a rotation of the splined disk 21. As best shown in Figure 4, the splined disk 21 is provided with a leaf spring 38 which extends tangentially with respect to the disk and is adapted to engage a ratchet tooth 39 which projects inwardly from the cylindrical wall of the countersunk opening 25. As a result of this construc tion, when the disk 21 is rotated counterclockwise, as viewed in Figure 4, incident to pulling of the knob 34 outwardly, the leaf spring 38 will drive the gear 23 in a counterclockwise direction.

Since the gears 23 and 22 are of the same size in the illustrated embodiment of the invention and the screw i4 is a single thread screw, the pitch of the helix on the shaft 28 and the permissible outward movement of the knob 34 are such as to effect one revolution of the gear 23 and hence of the screw l4 when the knob is pulled outwardly to the full extent. 'When the knob is released and the splined shaft 28 returned by means of spring 35, the disk 21 will rotate in a clockwise direction without driving the gear 23, due to the one-way driving connection between the leaf spring 38 and the ratchet tooth 39.

As a result of this arrangement, screw M will be rotated one revolution on each operation of the knob 34. It will be appreciated that, if desired, a double or triple thread screw may be substituted for the screw 4 and appropriate changes made in the gear ratios and spline angle to advance the envelopes It! the distance between sucforward motion of the rod 29 by engaging plate cessive threads on the screw for each operation."

of the knob 34 without departing from the principles of the invention.

In order to assist in holding the gear 23 against rotation on clockwise rotation of the disk 21, the face of the gear is preferably provided with a spherical recess 40 adapted to receive a springpressed ball 4| positioned within a suitable opening 42 formed in the wall of the housing 9. The position of the recess 40 is such that the ball enters the recess when the knob 34 is in its fully retracted position, illustrated in Figure 6, and the remaining parts are in the positions illustrated priate coin or coins.

velope off the right-hand end on each complete revolution. The envelopes which are discharged from the ends of the screws drop upon a belt 43 which is supported on pulleys 44 and 45 located in the lower portion of the machine. The pulley 45 is adapted to be driven in any suitable manner by an electric motor 46. When the motor is operated, the belt moves in the direction of the arrow in Figure 2 and carries the discharged envelope to the right through a discharge opening 41 in the front wall 33 of the machine. A stop member 48, provided with a pair of upstanding fingers 49, operates to stop the outward movement of the envelope, even though the belt continues to move. At the point at which the envelope is stopped by the fingers 49, it may be grasped and withdrawn from the machine by hand.

The remaining feed screws I2, l3, l5 and I6 are identical in construction and mode of operation to the previously described screw l4 and are operated by similar mechanisms. The only difference between the housings 1, 8, 9, l0 and II resides in the fact that they are displaced angularly about the common axis of the screws I2 to H5, in the manner best shown in Figure 4, with the result that the axes of the pull rods are circumferentially spaced about the common axis of the screws. Thus, as best shown .in' Figure 4, the rearmost housing H is angularlydisplaced in a clockwise direction with respect to the housing 9 and contains a drive gear which meshes with a gear 5| fixed to the feed screw I6. The drive ear 50 is operated by a pull rod 52 in the same manner as the gear 23 is operated by the rod 29. Housing l0 similarly contains a drive gear 53 which is operated by a pull rod 54, and the gear 53 meshes with a gear 55 on the screw l5. The housings T and 8 are displaced angularly in a counterclockwise direction with respect to the housing 9, and contain similar screw driving gears and associated parts.

The forward ends fo all of the pull rods carry square rods similar to the square rod 32 associated with pull rod 29. Thus, a square rod 55 is fixed to the end of pull rod 52, a square rod 51 is fixed to the end of rod 54, a square rod 58 is fixed to the end of the rod (not shown) which operates screw 13, and a square rod 59 is fixed to the end of the rod (not shown) which operates screw 12. All five of the rods project through the forward end of the machine and carry pull knobs 60, 6!, 34, 62 and (53, respectively, with the result that an article may be discharged from any desired screw by pulling the appropriate knob.

Means are provided for latching all of the square rods 56, 51, 32, 58 and 59 in their inward positions, illustrated in the drawings, and for releasing the rods upon the deposit of an appro- This means includes a pivoted latch associated with each of the rods. Thus, as shown in Figure 6, a supporting plate 64 positioned within the casing of the machine pivotally supports a latch 65 which is adapted to engage within a notch 66 formed in the upper side of the all pivoted on the plate 64, engage, respectively,

in similar notches in the square rods 56, 51, 59

and 59 in the manner best shown in dotted lines in Figure 3. Each of the latches is preferably provided with a spring for holding it in-latched position, suitable springs for this purpose being indicated at H, 12, 13, 14 and 15. While the latch 65 is pivoted solely on the plate 64, it will be noted from Figure 6 that the remaining latches are spaced rearwardly of latch 65 and hence are pivoted on pins which extend between the plate 64 and the plate 39. Suitable spacing sleeves are provided on the pins on either side of the latches, as best indicated in connection with the latch 61 in Figure 6. As there shown, the latch 61 is pivoted on a pin 16 which extends between the plates 39 and 64, and the latch is held in proper position along the pin by means of a pair of sleeves 11 and 16.

) the armature 69 is connected by means of a cable BI to the latch 61, the cable BI being trained over pulleys 62, 83 and 84. The pulley 82 is one of a plurality of pulleys journaled on a pin 85. Latch 68 is operated by a cable 86 which is trained over pulleys 81 and 88, the pulley 81 being journaled on the pin 85 and the pulley 89 being journaled on a pin 99 which carries the previously men- 7 tioned pulley 83. A flexible cable 9I connects the armature 89 t0 the latch 65, and cables 92 and '93 connect the armature to the latches 69 and 19. The cables 92 and 93 are trained over pulleys similar to those provided for the cables BI and 86. As a result of this construction, energization of the solenoid 19 disengages all five of the latches from the square rods and de-energization of the solenoid permits return movement of the latches under the influence of the latch operating springs.

Means are provided to prevent more than one of the pull knobs 69, 6I, 34, 62 and 63 from being pulled outwardly at one time. This means comprises a pivoted latch plate 94 carried between a plate 95 and the previously mentioned plate 64 on a pin 96. As best shown in Figure 3, the plate 94 is provided with five notches 91, 96, 99, I99 and I9I adapted to co-operate, respectively, with specially formed notches I92, I93, I94, I95 and I96 in the underside of the square rods 56, 51, 32, 58 and 59. As best shown in the developed sectional view of Figure 7, the notches in the latch plate and the square rods are so arranged as to permit withdrawal of only one of the square rods at a time. This result is achieved by beveling the rear edges of the slots 91, 98, 99, I99 and I9I in the plate 94 to form cam surfaces adapted to co-operate with similarly beveled surfaces formed in the rod notches to effect a shift of the latch plate when one of the rods is pulled in a direction to align the notch in the plate with the rod, such alignment being necessar by reason of the fact that the width of the notches in the plate is equal to the width of the square rods. Thus, as shown in Figure '7 in connection with the square rod 32, the notches in the square rod are provided with beveled cam surfaces I91 and I99 adapted to co-operate with beveled surfaces I99 and H9 on the rear. edges of the notch notches 91, 98, I99 and IN are out of alignment with their associated rods 56, 51, 59 and 59. Accordingly, none of the rods may be pulled outwardly except the rod 32. If, however, it is desired to pull the rod 56, the beveled cam surface I I9 on the rod notch will engage the beveled surface III on the rear edge of the notch 91 and swing the latch plate in a counterclockwise direction about the pin 96 until the notch 91 aligns with the rod 56. This movement of the latch plate will place all of the remaining notches out of alignment with their associated rods. The mechanism operates similarly when any of the other rod is pulled outwardly, with the result that in no case can two rods be pulled at the same time, even though all of the solenoid operated latches are released.

v An important feature of the above described 'means for preventing movement of more than one of the rods at a time resides in the fact that the interlocking latch plate 94 is pivoted and hence may operate relatively freely. To facilitate such pivotal action, the latch plate 94 is preferably .spaced slightly from'the plate '95, as shown in Figure 6, and is so constructed that it will not deflect'sufficiently to engage the plate 95 except upon'application of a force greater than that necessary to swing it about its pivot pin 96.

The operation of the machine is controlled by a coin mechanism and an electric circuit, which are illustrated diagrammatically in Figures 8 and iswitch'esof the other set operate to return the coins deposited in the machine when a knob is pulled and the associated article supporting screw is empty. The switches of the first set are conventional limit switches mechanically associated with the "square bars 56, 5,1, 32, .58 and 59. Thus, as best shown in Figure 6, a limit switch H2 is supported by means of a bracket II3 beneath the square rod 32 with the opertaing button II4 of the switch contacting the underside of the rod. :The arrangement is such that when the rod is pulled outwardly to its fullest extent, the operat- 55' ing button clears the left-hand end of the rod 32 and thus is free to move upwardly. When the rod is returned, it engages the button and depresses it to the position shown in Figure 6. Similar switches are similarly associated with each of the remaining rods 56, 51, 58 and 59. As hereinafter more fully pointed out, each of these switches controls two separate circuits and closes .I I9, I29, I2I, I22 and I23, which are so associated,

respectively, with the screws I2 to I6 that they remain closed as long as any article is supported on the screw with which they are associated,

but open when the last article is discharged from that screw. Thus, the switch II9 comprises a flexible leaf spring I24 which is mounted at one end on a rod I25 carried by the housing 1' and which carries at its opposite end a switch contact I26 which is adapted to co-operate with a contact I21 carried by an arm I28, which is also mounted on the rod I 25. The underside of the leaf spring I24 bears lightly on the upper edge of the envelope which is supported on the outer extremity of the screw I2 and is held by the envelope in its uppermost position, in which the contact I26 remains in engagement with the contact I21. As soon as the last envelope is discharged from the screw, the leaf spring I24 is permitted to deflect downwardly and thus open the contacts. The remaining switches I20, I2I, I22 and I23 are similar in construction and mode of operation and are illustrated diagrammatically in Figure 9.

As shown in Figure 8, the coin mechanism includes a coin deposit opening I29 adapted to receive coins of the appropriate denomination. Coins deposited in the slot I29 enter a slug rejector I30, which may be of conventional construction and which serves to separate bogus or defective coins from genuine coins, the former being discharged into a chute I3I and the latter into a chute I32. Chute I3I communicates directly with a coin return pocket I33 accessible from the exterior of the machine. Legitimate coins discharged through chute I32 pass a pivoted switch operating arm I34, which is thus swung in a clockwise direction to momentarily close a contact between the arm and a stationary contact I35. The coins then pass downwardly and come to rest on the fiat surface I36 formed on a member I31 which is pivoted by means of a pin I38 in such a position that the fiat surface I36 closes the lower end of the chute I32. Thus, the coins deposited in the machine initially come to rest at the lower end of the chute I32 and in engagement with the surface I36. The member I31 is provided wih a pair of coin chutes I39 and I40 which merge with a downwardly projecting chute I4I which, in the normal position of the parts illustrated in Figure 8, terminates above a relatively fiat surface I42 which closes the lower end of the chute I. A pair of solenoids I43 and I44 is pivoted by means of pins I45 and I46 to the casing and has its movable armatures connected by means of links I41 and I48 to opposite sides of the chute I4I. Springs I49 and I50 normally urge the links I41 and I48 toward the chute HI, and thus serve to center the chute in the position illustrated. On energization of either of the solenoids I43 or I44, the pivoted element I31 is swung at its lower end toward the energized solenoid. Thus, on energization of solenoid I43, the element I31 is rotated in a clockwise direction, as viewed in Figure 8. This permits any coins which were resting on the surface I36 to pass downwardly through the chutes I39 and I M into an auxiliary coin return chute II which communicates with the pocket I33. Energization of solenoid I44 swings the element I31 in the opposite direction and permits the coins to pass downwardly through chutes I 40 and MI into the reservoir I52.

As shown in Figure 9, the electrical circuitv comprises a pair of electric supply lines I53 and ergized after switch I35 opens.

The contacts I58, I59, I60, I6I and I62, which comprise one of the two contacts in each of the switches H2, H5, H6, H1 and H8, are connected in parallel with each other and in series with the coil of a relay I63 across the lines I 53 and I54. The switches II9, I2I, I22 and I23 are connected, respectively, in series with the contacts I64, I65, I66, I61 and I68 by means of lines I69, I10, I1I, I12 and I13, and the lines I69 to I13, inclusive, are connected in parallel with each other and in series with the coil of a relay I14 across the lines I53 and I 54.

The relay I55 has a normally open contact I15 in a line I16 which contains the latch release solenoid 19, as a result of which energization of the relay I55 effects release of the latches 61, 68, 65, 69 and 10. The relay I63 is provided with a holding circuit I11 containing a normally open contact I18 of the relay I63 and a normally open contact I19 of the relay I55. The relay I14 is provided with a holding circuit I19 containing a normally open contact I of the relay I14 and a normally open contact I8I of the relay I55. The main circuit of the relay I14 also contains a normally open contact I82 of the relay I55. The relay I 63 is provided with a normally closed contact I63 in the main circuit of the relay I55 and a normally open contact I84 in the circuit of the coin return solenoid I43. The contacts I83 and I84 of relay I63 are of the delayed action type, being connected to the relay armature by a spring and associated with a one-way acting dashpot in the usual manner. Contact I83 is so arranged that its opening movement is delayed for a pre determined period after energization of relay I 63, while contact I84 has a similar but shorter delayed closing period. Thus, for example, the dashpot mechanism may delay the closure of contact I84 for two to three seconds after the relay I 63 is energized, and the dashpot associated with contact I83 may delay the opening of the contact for approximately six seconds after the relay is energized. Contact I83 will close and contact I84 will open immediately upon de-energization ofthe relay I63.

The relay I14 contains a normally closed contact I85 in the main circuit of the relay I63, a normally open contact I86 in the circuit of the coin deposit solenoid I44, and a normally open contact I81 in the circuit of the motor 46.

The operation of the mechanism is as follows. On deposit of a coin in slot I29, switch I35 will be closed momentarily, thus energizing relay I55, and the coin will come to rest on the flat surface I36 of the element I31. Energization of relay I55 closes contact I15 and thereby energizes the latch release relay I19 and makes it possible for any selected one of the pull knobs 60, GI, 34, 62 and 63 to be pulled outwardly. Thereupon, the operator will pull a selected knob. When the selected knob is pulled outwardly to its fullest extent, one of the limit switches H2, H5, H6, H1 or II8 will close, at least momentarily. If the screw associated with the knob which is pulled is carrying one or more articles, the corresponding switch of the group consisting of switches II9 to I23, inclusive, will be closed and, therefore, both of the relays I63 and I14 will be simultaneously energized. Energization of relay I14 immediately opens contact I35 and thus de-energizes relay I63 before the delayed closing contact I 84 of relay I63 can close. Therefore, the coin return solenoid I43 will not be energized. On the contrary, relay I14 will close contact I66 and thus energize the coin deposit relay I44 and at the same time the relay I14 will establish a holding circuit for itself by closing contact I80. The coin deposit relay I44 will remain energized until the circuits through relay II4 are broken by the opening of contacts IBI and I82 of relay I55. This will occur as soon as the delayed opening relay contact I83 of relay I63 opens the circuit through relay I55. In the meantime, the contact I81 of relay I14 will have closed on energization of the relay I14 and started the motor 46. The period of delay in the opening of contact I83 is made sufiicient to insure not only complete operation of the coin deposit solenoid I44, but a sufflcient period of operation of the motor 46 to completely discharge an article released from the rearmost supporting screw I6. As soon as this period has been completed, the opening of contact I83 will de-energize relay I55 and return all portions of the electrical circuit to the position shown in the drawings. It is desirable to deenergize the latch solenoid I9 as soon as the control knob is pulled out to its fullest extent. Accordingly, there is provided in connection with the relay II a normally closed contact I88 in the circuit of the solenoid 19 which will open and de-energize the solenoid 19 as soon as one of the knobs is pulled outwardly.

In the event that the screw corresponding to the selected knob is carrying no articles, the corresponding switch of the group II!) to I23 will be open and, consequently, relay I'I4 will not be energized when the knob is pulled fully out. This prevents operation of the coin deposit solenoid I44. Nevertheless, the relay I53 will be energized, thus .closing contact I84 after a short delay and energizing the coin return solenoid I43. This returns the deposited coin to the coin return pocket I33.

While only one preferred form of the invention is illustrated and described herein, it will be apparent that variations in the design and arrangement may be indulged in without departing from the spirit of the invention or the scope of the appended claims. In this connection, an important feature of the invention resides in the use of cantilever mounted supporting and feeding screws for the articles dispensed by the machine. Such screws are of peculiar utility for use in dispensing articles such as phonograph records in paper envelopes, and it will be apparent that the advantages of such a construction may be realized regardless of the nature of the mechanism utilized to rotate the screws in a step-by-step manner. Thus, other forms of manually operated mechanisms may be employed or the screws may be rotated by one or more electric motors, if desired.
