This invention relates to vending machines. An object of the invention is to provide an improved vending machine including a support for the merchandise contained in the machine, a 5 novel form of intermittently operative mechanism for moving the merchandise along the support and discharging the articles of merchandise individually therefrom.

Another object of the invention is to provide an improved vending machine comprising supporting and delivering mechanism for the articles to be delivered from the machine, and improved means for dividing or severing diierent articles in the machine and delivering divided or severed portions thereof only, while retaining in the machine the remaining portions of said articles until a subsequent operation of the machine is performed for the purpose of delivering therefrom said divided or severed portions of said articles.

In the specic embodiment shown, my invention is designed and adapted for use in dispensing articles of merchandise, such as ice cakes of a certain size and value, and is equipped with mechanism for dividing or severing ice cakes contained in the machine so as to provide ice cakes of smaller size and value and discharge the divided and severed portions of the ice cakes instead of complete undivided ice cakes of the original size, and another object of the invention is to equip the machine with mechanism to perform the above operations optionally and satisfactorily.

Various other objects and advantages of my improved vending machine should be readily apparent from the following description, reference 35 being made to the annexed drawings, in which- Fig. 1 is a plan view of the principal mechanism comprising the present invention, parts being in section.

Fig. 2 is a vertical cross sectional View on the line 2-2 oi Fig. 3.

Fig, 3 is a vertical sectional view approximately on the line 3--3 of Fig. l, also indicated on the line 3 3 of Fig. 2.

Fig. 4 is a view showing the relationship of the start device for a motor controlling one of the discharge mechanisms and the stop device for a motor controlling another discharge mechanisrn.

Fig. 5 is a View showing the stop device for that motor having its starting device shown in Fig. 4.

In the construction shown, the ice cakes I are mounted on spaced supports 2, each having an upwardly extended ange 3 along its outer edge to retain the ice cakes on the supports. These (Cl. 12E- 23) supports 2 are separated by an intervening space 0,. Arms 5, attached to an endless sprocket chain t, extend upwardly through the space 4 and engage against the rear ends of the respective ice cakes l. When the chain t is operated in 5 the direction of the arrows l, the ice cakes i are move-d along the supports 2. This operation of the chain (i is intermittent and each intermittent movement of said chain is sufficient only to discharge the ice cake l at the front from the supports 2 onto an inclined chute 8 leading to a door opening d through the wall lil forming an enclosure or casing confining the mechanism and the merchandise. The chain S and cooperating mechanism constitute dispensing means for cakes of large size. A door ii, supported on hinges l2, may be opened to permit the removal of the ice cake from the machine and then closed to prevent access to the machine until another operation of the mechanism, or until the door is opened for other purposes.

Ihe inner portion of the chain t is supported on a sprocket wheel i3 mounted on a shaft I4, and the outer portion of said chain 6 is supported on a sprocket wheel i5 attached to a rotary shaft i6.

A motor il (Fig. l), through a conventional speed reducing device i8, rotates a shaft i9 having a sprocket wheel 2U attached thereto and engaged by a sprocket chain 2i, which also engages a sprocket wheel 22 attached to the shaft i6.

Any suitable mechanism for controlling the starting and stopping of the motor I'I may be provided. Various types of coin controlled devices for starting and stopping motors of this type are known, and I contemplate the use of some such device in connection with the present invention. The stop mechanism may be operated by the sprocket wheel 22 by means of pins 23 projecting from said wheel and, during rotation of said wheel, engaging and ope-rating a known type of stop switch 2li in the circuit controlling operation of the motor il. The specic manner of assembling and operating the start and stop devices for the motor ll is unimportant insofar as the present invention is concerned, because the motor il may be started and stopped by any one of numerous forms of devices.

As clearly shown in Fig. l of the drawings, in each unoperated position of the mechanism controlled by the motor il, an ice cake l is at the front end of the supports 2 in position to be discharged into the chute 8. Each intermittent operation of the motor il moves the arm 5 from the position of the arm 5 at A to the position of the arm 5 at B. This discharges the ice cake l that is in front of the arm 5 at the position A onto the chute 8 and advances another ice cake to the same position. Thus, in each unoperated position of the motor il, there is an arm 5 at the position A and an ice cake l immediately in front of such arm in position'to be discharged onto the chute 3 or to be laterally moved onto a laterally extended support 25 and automatically and as an incident to said lateral movement divided or severed to form two smaller ice cakes 25 and 21.

In the embodiment shown, my invention comprises an additional motor 2S operating through a conventional speed reducing device 29 to rotate a shaft 3Q and a pinion 3l attached to said shaft. The pinion Si is in constant mesh with a large gear wheel 32 mounted on a trunnion 33 and rotated by the pinion 3l in the direction of the arrow 34 (Figs. S and 4). This gear wheel 32 is formed with a cam 35 on one side engaged by a roller 35 supported at the side of a lever 3l pivoted for swinging movements on a stationary support 38.

A link 39 has one end pivoted to the lower end of the lever 3l and the opposite end pivcted to a lever 4). The lower end of the lever is mounted on a pivot [il projecting from the machine frame 42, and the upper end of said lever iii is pivoted to one end of a link d3, which has its opposite end pivotally connected with a reciprocable carriage member All. The carriage member 44 may be supported and guided in its reciprocating movements by grooved rollers r5.5 and retained in position on said rollers l5 by rollers 'it engaging the upper side of said carriage member 44.

A cross head il is connected with the front end of the reciprocating carriage member lli and has a vertical series of forwardly extended prongs i8 in connection therewith opposite the center of the ice cake l that is in front of the arm at the position A. The cross head supports bearings 49 in which rods 5@ are supported for sliding movements. The forward ends of the rods 5t support a cross head 5i adapted to engage against the adjacent side of the adjacent ice cake l and move said ice cake i from the supports 2 to the laterally extended support 25 during each complete revolution of the cam wheel 32. Forwardly extended arms 52, in connection with the cross head 5 i engage the adjacent marginal end portions of the ice cake l when said cross head 5i is moved forwardly and thereby center and retain the ice cake i in centralized position with respect to the cross head and prevent forward or rearward sliding movements of said ice cake. In the retracted or unoperated position of the cross head 5i, the arms 52 are beyond and out of engagement with the ice cake l. The cross head 5i has in its central portion a vertical slot 53 (Fig. 3) through which the prongs i3 may be projected when the cross head 5i is held from further movement, and said prongs continue to move. Springs 555, mounted on the rods 56 between the bearings i9 and the cross head 5l, hold said cross head in its forward position but permit said cross head 5l to remain stationary during continuous forward movement of the cross head dll and the prongs 48.

A segmental rack 55 is attached to the opposite side of the gear wheel 32 from the cam 35 and intermittently engages and disengages a pinion 55 attached to a rotary stud shaft A pinion 58, attached to the rotary stud shaft 5l,

is in constant mesh with a pinion 59 attached to a rotary shaft 6) and having attached thereto a pinion 6l in constant mesh with a pinion 62 attached to a vertical shaft 653 beyond the outer end of the laterally extended support 25. The upper end of the shaft 63 has two vertically spaced sprocket wheels 54 attached thereto at and above the outer end portion of the laterally extended support 25 (Fig. 3). A pair of sprocket chains 65 engage the sprocket wheels 64 and complementary sprocket whe-els 66 attached to a vertical shaft 6l at the opposite side of the laterally extended support 25. A series of plates or bars 63, having laterally extended prongs t8a rigid therewith, are attached to and operated by the chains 65. The chains 55 and associated parts constitute mechanism for splitting large cakes into cakes of small size and for dispensing said cakes of small size.

Thus, the chains 65 are operated during onehalf of each complete revolution of the gear wheel 32.

The motors Il and 28 cannot be operated simultaneously. Each of said motors may be operated only intermittently and each motor may be operated only during the time that the other motor remains unoperated.

A starting device for the electric circuit controlling the motor il is operated once during each complete revolution of the wheel 32 by a pin i0 attached to and projecting laterally from said wheel. Additionally the electric circuit controlling the motor l may be operated by any coin control mechanism of any known type associated with the electric circuit while the starting device 69 remains in its unoperated position and while the wheel 32 remains unoperated.

A stopping device il controlling the electric circuit for operating the motor 28 is operated twice during each revolution of the gear wheel 32. The stopping device 'il is operated once during each revolution of the wheel 32 by a pin l2 attached to and projecting laterally from the gear wheel 32 and is also operated once during each complete revolution of the gear wheel 32 by another pin i3 attached to and projecting from the gear wheel 32.

A rigid member 'i4 is mounted between the shafts 653 and @i and may support bearings for said shafts and may also function as an abutment for that one of the plates or bars 68 having its prongs 58a in position to divide or sever the block of ice i driven from the supports 2 to the laterally extended support 25 in order to form the smaller ice cakes 26 and 2l.

A guide member 'E5 is mounted on a pivot 16 and is yieldingly supported in raised position by an actuator l?. This guide member in its unoperated position extends above the supports 2 and 25 (Fig. 3) inclining upwardly from the support 2 toward the support 25, so that the ice cake I may be moved laterally from the supports 2 onto the support 25. When the ice cake l moves onto the guide l5, said guide is thereby moved downwardly and is held in its downward position until the ice cake passes said guide and is placed on the support 25. Thereupon the actuator 'i1 raises the guide '."5 opposite the two smaller ice cakes 25 and 2'?, which had been obtained by splitting the ice cake i that had been moved as aforesaid.

Vlhen the ice cake I is moved from the supports 2 by operation of the cross head 5l and engages the centered prongs 53a, the springs 5A yield and permit the prongs 48 to engage and pierce the adjacent side of the ice cake I while the prongs 58a engage and pierce the directly opposite side of the ice cake l. The cross head 41 continues to move forwarcuy until the prongs 48 for the greater portion or" their length pierce the ice cake I, the cross head 5i continuing also to move forwardly, which action results in the prongs 45 and 58a dividing or severing the ice cake, as shown in Fig. i, to provide the two smaller ice cakes 25 and 21. Continued forward movement of the cross head 5l moves the ice cake I, or the smaller ice cakes 25 and 21 obtained by the splitting thereof, beyond the guide 15 and onto the laterally extended support 25, whereby the actuator 11 raises the guide 15.

The mechanism illustrated in Figs. l, 2, and 3 may be used in combination with or without the motor stop devices il and 24, shown in Figs. i and 5, and in combination with or without the motor start device 65, shown in Fig. 4. These parts are omitted from Figs. l, 2, and 3 but are suiiciently illustrated in their relationship to their cooperating and operating relations in Figs. 4 and 5.

As shown in Fig. 4, the pin 12 is about 90 in advance of the pin i3 and said pin 'i3 is about in advance of the pin l5. The gear wheel 32, rotating in the direction of the arrow 32, has caused the pin 12 to engage and move th-e motor stop device 1I for the motor 2B from the solid line position to the dotted line position. When the device 1i is moved from solid line position to dotted line position, the motor 2S is thereby immediately stopped and said device 1l is automatically, by its 1Known construction, returned to the solid line position but does not again start the motor 28. The roller 35 has just left the low part of the cam 35 and entered the high part of said cam and has, therefore, completely retracted or moved to its unoperated position the carriage member M and the parts carried thereby, including the cross head 5l and the prongs d8.

The pin 15 has also just operated the start device 69 for the motor I1 from the solid lin-e position to the dotted line position and released said start device 59, which immediately returned from the dotted line position to the solid line position. This starts the motor l1, which continues to operate and, through the connections described, to rotate the sprocket wheel 22 onehalf of a revolution, causing one of the two diametrically opposite pins 23 to engage and move the motor stop device 2li for the motor l1 from the solid line position (Fig. 5) to the dotted line position and thereby stop said motor l1. This operation of the sprocket wheel 22 by the motor I1 operates the chain 5. But the moto-r I1 does not start to operate until about the time that the motor 28 is stopped, which is after the carriage member 4d and the parts carried thereby have been completely retracted or returned to their starting position by the parts operated by the cam 35.

In the position of the parts shown in Figs. e and 5, either of the motors il or 28 may be operated, but not both simultaneously, it being intended to employ a suitable interdependent means (not shown) to prevent simultaneous operation of these motors when the parts are in said positions. The motor l1 may be set in operation without operating the starting device E59, as is well known. When the motor I1 is started without use of the starting device 59, the sprocket wheel 22 is rotated in a clockwise direction (Fig. 5), thereby operating the chain B to discharge the ice cake I at the front and to move another cake of ice forwardly to position for subsequent discharge. The pin 23, that is farthest from the stop device 25, operates said stop device from the solid line position to the dotted line position and releases said stop device, thereby stopping the motor l1 when a cake of ice l is in position either for discharge by a subsequent operation of the chain 5 or forv movement laterally onto the laterally extended support 25.

When the motor 28 is started to deliver the smaller ice cake 26, the motor stop device 1I for said motor 28 is operated after the .gear wheel 32 turns about 90 in the direction of the arrow 34. During this movement, the arm 31 and the connections operated thereby remain unoperated. This advances the pin 13 to the position occupied by the pin 12. This 90 rotation of the gear wheel 32 engages the segmental rack 55 with the pinion 5G and thereby, through the gearing shown, operates the chains 55 to cause the prongs 68a to move forwardly and discharge the ice cake 26 from the support 25 to the chute 8. Since the gear wheel has been rotated only about 90, the pinion 56 remains in mesh with the segmental rack 55 for another operation of the chains 55. Then during the next operation of the motor 28, the chains 65 are operated to discharge the ice cake 21 from the support 25 onto the chute 8, because during the preceding operation the ice cake 21 had been move-d forwardly to the position previously occupied by the ice cake 25. The motor 28 continues to operate until the pin 12 again engages and operates the stop device 1I, because the pin 15 does not engage nor operate the stop device 1I. The start device 59 for the motor I1 is not operated by either of the pins 12 or 13, because said pins 12 and 13 do not extend far enough from the rack member 55 to engage the start device 69. The continued rotation of the gear 32 causes the roller 35 to enter the low part of the cam 35 after the ice cake 21 has been discharged and after the segmental rack 55 has passed out of engagement with the pinion 56. When the segmental rack 55 passes out of engagement with the pinion 56, said pinion 56 stops and the chains 55 also stop in a position in which the prongs 53a are so located as to split a cake of ice I into the two approximately equal parts 26 and 21. During the time that the roller 36 is operating from the high part to the low part of the cam 35, the lever 31 is operated, thereby operating the carriage member 44 and the cross head 5I to move an ice cake I from the supports 2 to the support 25 and to cause the prongs 48 to pierce the ice cake and, in cooperation with the prongs 68a, to split the ice cake into two approximately equal parts 25 and 21. Then the lever 31 is operated during the time that the roller 36 is moving from the low part to the high part of the cam 35, which is to the position shown in Fig. 3. At the time the roller 36 enters the high part of the cam 35, as shown in Fig. 3, the pin 12 operates the stop device 1I to stop the motor 28. After the cross head 5I has been retracted, the pin 10 operates the start device 69 and thereby starts the motor I1 to advance another ice cake I to position for discharge by a subsequent operation of said motor I1, or for movement laterally onto the laterally extended support 25, as described.

It is now clear that this invention comprises optionally operable means for discharging selected cakes of ice and for dividing or severing larger cakes oi ice to provide smaller cakes. It is also clear that my invention comprises mechanism under control of the dispensing mechanism for the smaller cakes of ice to remove a larger cake of ice from the dispensing mechanism therefor and to place the larger cake o1" ice on the dispensing mechanism for the smaller cakes and simultaneously divide or sever the larger cake to obtain the smaller cakes.

By my improved mechanism, the purchaser may be served with the size of ice cake that is desired and the mechanism of the machine is controlled automatically by the dispensing mechanism to reload either dispensing mechanism when a vacancy occurs. In a broad aspect, my imf proved vending machine embodies ice storage means, mechanism under control of the motor Il for dispensing ice cakes of a predetermined size, mechanism comprising the chains 65 and cross head 5i for dispensing ice cakes of a smaller size, and means comprising the chain 6 for supplying both mechanisms from the same storage means.
