YORK, A CORPORATION OF NEW YORK ICE VENDING MACHINE Application filed Bccemher 15, 1924. Serial No. 756,132.

In the present state of the art manufactured ice is generally distributed both by house-tohouse deliveries and from cash and carry stations. With the latter it is necessary to maintain an attendant or salesman, and to suit the requirements of the public it is necessary that the station should be open at all hours. Also the demand is irregular, depending as it does largely upon the condition of the weather. Thus the average cost of sale is relatively high.

It is the primary object of the invention to dispense with the salesman by the provision of an automatic vending machine. On account, however, of the nature of the material dispensed, it cannot be handled as is usual with other types of vending machines, but requires special instrumentalities for that purpose. My invention therefore consists: first, in means for automatically discharging an ice cake of predetermined size and. weight upon the insertion of the coin, slug or other controlling means; second, in the means for storing the ice to be vended in large cakes and for effecting the severance of the small cakes therefrom just in advance of delivery, and; third, in various features of construction as hereinafter set forth.

1 is a suitable housing or storage chamber for the ice to be vended, which is preferably provided with suitable heat insulation (not shown), maintaining the temperature therein as low as possible without artificial refrigeration. lVithin the housing 1 is arranged a suitable carrier 2 on which are placed large cakes of ice 3, such as delivered from the freezing cans. These cakes have preferably been previously scored to divide the same into small sections of equal weight, such for instance as -lb. or -lb. cakes. The cakes are scored both longitudinally and transversely, each transverse score marking a 50-lb. section, while the central longitudinal score divides said section into smaller 25-lb.

pieces. 7

For convenience in loading the carrier with ice, the housing is provided with a rear door 4:, which when turned down will form a platform on the level of the carrier, which serves to first receive the ice cakes and from which they may be slid onto the carrier. At one end of the housing there is arranged a cross feedor for intermittently advancing one of the ice cakes longitudinally into engagement with the cut-off mechanism. This cut-off mechanism is actuated, as will be hereinafter described, to successively sever small cakes from the large cake in cooperation with delivery mechanism by which each small cake is deposited in a chute through which itpasses to the outside.

As has been stated, the delivery of each ice cake is effected by the insertion of a coin or slug which controls the operating mechanism. Each coin or slug thus inserted accomplishes: first, the delivery of a small cake of ice, and in alternate operations, the severing of such small cake from the large cake and the feeding of the cakes so as to suecessively present the same to the cut-off delivery mechanism. Various specific forms of mechanism may be employed for accomplishing such functions, but as shown the construction is as follows:

Vvithin the housing 1 and at one side ofthc carrier 2 is arranged a motor 5 drrvmg, through the medium of the worm gearing 6 and sprocket chain 7, a sprocket 8 (Fig. 2)

on a shaft 9. The sprocket is normally freely revolubl on the shaft 9, but may be coupled therewith by a clutch 10, which when tripped will revolve the shaft through one revolution, then automatically releasing the same. Mounted on the shaft 9 is a grooved cam wheel 11, (see Fig. 6) which actuates a bell crank lever 12 having one arm 1266 connected by a rod 13 with a severing blade 1a. This blade is arranged in registration with the longitudinal score in an ice cake section, which has previously been severed from the main cake and deposited on an inclined way 15, being supported at its lower end by a hinged arm 16. See F ig. 2. This arm is also controlled by the cam 11 through the medium of a second. arm 17 of the bell crank lever 12, link 18, bell crank lever 19 and link '20, the arrangement being such that the operation of the cam first severs the ice case section supported on the way 15 and then by swinging the arm 16, drops the lower severed piece onto the chute 21 through which it is delivered to the outside. The further operation of the cam 11 returns the swinging arm 16 and withdraws the blade 14 so that the up per half of the ice cake can slide down the way 15 into engagement with said arm 16. In this position it is ready to be delivered in a succeeding cycle.

For depositing an ice cake section on the inclined way 15 there is provided the transverse feed for the large ice cake, previously referred to, and means for intermittently severing said cake along one of the transverse scores and deliiering the severed section to said inclined way 15. This mechanism is actuated from a shaft which is driven at half the speed of the shaft 9 through the medium of a two to one gearing 23. (See Fig. 6.) Upon the shaft- 22 is a grooved cam 2 1; which actuates a rock arm 25 on a rock shaft 26, which latter through the medium of a rock arm 27 and link 28, (see Fig. 1) actuates a rock arm on a rock shaft 30 extending transverse to the

shafts

9 and 22. On the right hand end of this shaft (Fig. 2) is mounted a sector gear 81 which engages a pinion o2 carrying a pawl for operating a ratchet wheel 3 1 connected to a sprocket (see Fig. 3). This sprocket drives a chain 36, which extends across the end of the housing in a plane transverse to that of the carrier 2. Connected to this chain is a roller "arriagc 1:38 which travels upon guideways .39 and provided with a pusher arm l0 (Figs. 1 and 2) for engaging the rear end of one of the large ice cakes on the carrier 2. Thus whenever the cam 2i actuates the rock arm 25. the carriage 38 will be advanced along the ways 39, carrying the ice cake forward.

Artificial ice cakes are usually of a tapering form so as to be readily removable from the freezing cans so that in dividing such a cake into pieces of uniform weight, the spacing between transverse scores is not equal. Therefore, to successively register such scores with a severing blade in the fixed plane, it is necessary to differentially feed the ice cake. This I have accomplished by arranging parallel to the ways 39 a control bar l1, which is detachably mounted so that it may be exchanged for substitute bars where ice cakes of different size are placed in the machine. This control bar is provided with a series of notches 42 so spaced as to correspond with the divisions between the transverse scores on the tapered ice cake. The carriage 38 is provided with a dog 43 which rests upon the control bar so as to drop into the notches 42 and to thereby prevent return movement of the carriage. Such return movement would otherwise be automatically effected by a spiral spring a l actuating the sprocket 15 for the rear end of the chain 36. Thus by pro portioning the gears so as to actuate the carriage 38 in the forward direction an amount equal to the longest division between scores and then permitting it to be drawn backward by the spring 4%, the dog 43 engaging the notch 42 will arrest movement in a predetermined position. The pawl 33 which is gravity actuated functions as a tension regulating means for the spring 1 1 and will not become operatively engaged with the teeth of the ratchet wheel 3 t until the backward or return movement of the carriage 88 under the tension of the spring has been arrested by the engagement of the latch 43 with the adjacent notch 42, whereupon the pawl 33 will drop into operative engagement with the teeth of the ratchet wheel. Inasmuch, however, as the ice cake will not be moved backward with the carriage 38, there is provided a resilient pad 4:6 which bears on the forward end of the cake and. serves to press it rearward into contact with the pusher 40. This pad as shown consists of a rock arm fulcrumcd upon the bracket f? having an actuating arm d8 connected to the spring 4-).

The mechanism just described is actuated by one-half revolution of the shaft 22, which corresponds to one cycle of the main shaft 9, and is idle during the other half revolution or alternate cycle due to the shape of the cam. During the latter cycle the forward section of the advanced ice cake is split ofl by means of the following mechanism: is a reciproeating member carrying a series of severing blades 51, which exactly register with the transverse scores in the ice cake in diil'eront positions of advancement thereof. The member 50 is provided with rollers engaging a guide-way 53 and a rearwardly extending arm 54 is connected to a bell crank lever F5 actuated by the cam 24 on the shaft The timing is such that the severing blades 51 are advanced when the ice cake is stationary and will split off the end section. The

CJI

section thus split off is supported on a tilting shelf 57 (see Fig. 3) which is operated by a rod 58 engaging a cam groove 59 on the shaft 22. At the same time a cam on the shaft 22 engaging a roller 60g actuates a rod 61 connected to a segment bevel gear 62, which in turn actuates a bevel gear 63 connected to the spring pad 46 so as to withdraw the clamping pressure of this pad, permitting the severed section of the ice cake to be dumped onto the inclined way 15. The spring l8 serves to keep the roller 609 in contact with the cam 60 as well as to normally maintain resilient pressure on the pad 46.

The mechanism thus far described serves to transversely feed one of the large ice cakes step-by-step, registering the transverse scores with the severing mechanism, transferring the severed section to the inclined way 15, again severing this section while in engagement with said way and delivering one of the small sections to the chute 21. Such operations continue until the last section of the large cake has been delivered, after which the carriage 38 is returned to its initial position and another ice cake on the car "ier 2 is moved into engagement vith the pusher 40. The return of the carriage is accomplished by the partial rotation of the control bar 41, which disengages the dog as from the notches a2 and permits the carriage to be drawn backward by the tension of the spring 44 actuating the sprocket 48 and chain 36. However, it is necessary to release the pawl 33 from the ratchet 3% before such movement of the chain is possible. The rotation of the control bar a1 is effected by a roller G l on the carriage 38, which at the forward limit of movement of the latter engages a cam 65 on said bar and effects the desired rotation. A similar cam 66 at the rear end of the bar 41 engages the pin 6 M upon the return movement of the carriage and rotates the bar in the reverse direction. The rotation of the v bar by the cam 6-5 causes a cam 67 on the forward end of said bar to actuate a rock arm 68 on a vertical rock shaft 69, which at its upper end a finger 7 0 which is moved into the path of the pawl 33. This finger will thus disengage the pawl from the ratchet wheel and permit the spring eel to return the chain and carriage (see Fig. 5). During this return movement the last sect-ion of the ice block is held from displacement by an arm 71 (see Fig. 2), which was previously resting upon the top of the cake, but drops in rear thereof after the last forward feeding move ment. The arm 71 has a cammed face which will cause the same to ride over the forward end of the succeeding ice cake as it is brought into position by movement of the transverse carrier mechanism 38.

To place another ice cake in engagement with the transverse feeder, the carriage 2 is periodically operated by the following mechanism: Upon the main shaft 9, is a sprocket 72 connected by a chain 7 3 with a sprocket 7 4: revolubly mounted on a shaft 75 which extends to the driving sprockets for the conveyor 2. The sprocket 7 4; is normally declutched from this shaft, but may be coupled thereto by a clutch 7 6 adapted when tripped to impart to said shaft one-half revolution. The tripping of the clutch is accomplished by a lever 77 (see Fig. 5) which is actuated by the pawl 38 when the latter is disengaged from the ratchet wheel by the finger 70. This lever is connected by a link 78 with a lever 79 which withdraws the trip pin 80 of the clutch 7 6. Thus after the return of the carriage 38 the next cycle of operation will cause the movement of the carrier 2 a sufiicient distance to place another ice cake in engagement with the transverse feeder.

It is pointed out that while the finger 7 O is moved to operate the clutch for the conveyor 2 virtually simultaneously with the arrival of the carriage 38 at the front of the machine, the carriage will be returned to its starting position before another ice cake is moved into position by the conveyor 2 since the chain 36 is under the constant tension of the spring 44 and will return the carriage to the rear of the machine practically instantaneous with the release of the latch 43 and the pawl 33. The operating mechanism for the conveyor 2 is much slower in action than the spring controlled carriage return mechanism, as this conveyor is operated through the medium of a number of relatively slow moving parts.

As has been stated the shaft 9 makes one complete revolution each time the clutch 10 is tripped, thus effecting the delivery of one small cake of ice. The clutch is controlled by any suitable mechanism which may be operated by the proper coin or slug, but I have illustrated diagrammatically mechanism of the following construction: The motor 5 is controlled by a relay switch 81, which in turn is Controlled by a coin or slug operated switch 82. As indicated the coin inserted through the chute 83 will pass between a stationary contact Sfl and a movable contact lever 85, thereby closing an electric circuit 86 which operates the switch 81. This will start the motor 5, communicating motion through the worm gearing 6 and chain 7 to the shaft 9. Upon the chain 7 is a projecting link 87 which engages a rock arm 88 for operating the trip pin 89 of the clutch 10 (see Fig. 7). The clutch 10 is the type of clutch which is normally disengaged but is thrown into operation when tripped, continuing to operate for one revolution at which time it is swung out again by the pin 89. Thus after the starting of the motor the movement of the chain 7 will trip the clutch 10 causing one cycle of operation. he motor, however, continues to run until in the movement of thersplitrsecti the chain 7 the link 87 engages a lever 90, which operates a circuit opening switch 91 controlling the motor circuit. In the meanwhile, the delivery of the ice cake off from the way 15 will cause it to operate a rock arm 92,

which is connected to operate the contact lever 85, releasing the coin and permitting it to drop into a container 93. Thus the insertion of the proper coin or slug will start the motor, causing one cycle of operation, at the end of which the motor is again stopped.
