Referring to the draWingafidentiies a' Inconstructing the cabinet'therinner case" ing isfitted withinthe outerca'singfrom the top, the top wall of the outer casing being the last kpart 'to be applied. This top wall. -or closing the space containing the material .llisfastenedin place by spot welding or the like'as shown rat 5. The insulating material ybetweenv the vbottom of the` outer casingjan'd the bottom of the article/chute 6`being in- -sertedpror to the insertion of the inner :andback is filled with the insulating material.

The innery casing is divided into three compartments, two side compartments' 7 and y` 'anintermediatecompartment, the sidey com'- .partments receiving the merchandiseas iden-v -tilied'at '9. Y Suitablefwires 10,:are. streached or otherwisemounted -inthe side`compart` ments adjacent vthe walls Iof the intermediate compartment so as to retainv thegarticlesbf `merchandise in alignment oneabove the other, u

so that each article will beproperly dispensed.v The Ylower. ends of theside lcompartments vare provided with super-imposed* rmerchan- V casing, then the space between the sides, `front f 4-disesiipports lland,12,theuppersiipports 190' fil 11 being spring tensioned at 13 at their hinge connections, in such wise as to cause supports 11 to tilt downward, when a coin trip detentV 14 is released. Springs 15 are provided Connected to the supports 11 and being of sufficient tension to return the supports to their initial positions after they are allowed to drop, the springs 15 being connected to a rod 16- Y The cabinet is provided with coin slots 17, from which the coin chutes 18 extend, the coin chutes communicating with a coin receptacle or boX 19. The trip detents 1st are mounted adjacent the coin chutes and are associated with elements 20, which are pivoted. at 2Oa and have heads 20h, located in the passages of the coin chutes, so that when a coin is deposited in the slot it will engage with the head and thereby permit the support 11 to drop. When the trip detent is actuated, it cooperates with an article retaining device 22 to keep the remaining articles from dropping. Y

V-Thelower supports 12 are also spring Vtensioned at 23 adjacent their hinge mountings to return said supports to their initial positions. The lower supports act to support the article` of merchandise in such wise as to retard its tall to some extent. However the article ofmerchandise after being released trom the upper support 11, engages with the lower support and overcomes the tension oi the spring 23, allowing the4 article of merchandise to drop into the article chute.

Arranged inthe intermediate compartment are shelves 24 and 25, the latter4 being sup'- ported a substantial distance'above the tornier. These shelves 24 and 25 are constructed of some suitable metal open work and are adapted to support dry ice, such as frozen carbon dioxide for the purpose of keeping the merchandise cold andl from perishing,

Y namely keeping the merchandise-in a Jfrozen condition The lower shelf is fastened at 27 to the supporting rods 28, which in turn are connected to the lower shelf. Theupper shelf has handles29, whereby the two shelves may be lifted and removed from theV intermediate compartment, when the closure 30. is opened, such being the case when it is necessary to replenish the ice.
