The diskI-lfiis so'arrenged that its "periphery will beilhmetliately bee low a coin: chute 17, the luppe'r "elidlojf which tice l 'employ a eointubeequipped withjm' s5 ejecting mechanism whereby proper coins will be permittecl to passto thepoeket disk and operate the machine Whilefslugs' if other spurious devicesfwhic'h may be inserted will heejeeted and prevented from 'passir gto the operating mechanism; The disk 16 is formed With a pluralityofpockets 18 on its rear face and immediately adj aeent eachpoeketin the:

vperipheryof the disk is ashoulder, 19 which is adapted to be engagedby apewlw pivoted uponehe face P a 13 l -ndi e m l y to the disk by a retractile' spfing'Ql attached to the pawl and to the face plate; as clearly. shown'inrFig; l. i i

" The faceplate '13 is 'pr ovid d a noteh' 0 22 in its upper edge and on the inner side of the face plate is mounted a dog 23 which has its lower end below its pivot formed into a tooth'24 adapted to engage in one of the openings 8 in the flange of the door or closure 5. To the u or end of the dog 23 is pivoted a latch 25 W 1ch normally rests on the upper edge of the face plate 13 and is provided with a terminal lug 26 adapted attimes to seat in the notch 22 to thereby hold the dog out of engagement with the door or closure 5.

The door is provided near its upper end with a lifting lug or finger-hold 27 whereby it may be ralsed to its initial position.

U on reference to the drawings, more particu arly Fig. 4, it will be noted that the weight of; the door 25' is carried by the teeth 9 of the wheel10and consequently there is a constant tendency of the doorto descend by the force of gravity. This tendency, however, is resisted by the pawl 20 which engages the stop shoulders 19 on the disk 16 inasmuch as said disk is secured to the shaft 12 to which the wheel 10 is also'secured. When I a coin, indicated at 27 is inserted, it passes at once to the periphery of the disk 16 and partly enters the uppermost pocket 18, as shown in Fig. 1, coming to rest upontheedge of the ocket and against the end of the pawl 20. If the door 5 be now given a slight up,-

' ward movement, the wheel 10 andconsequently the disk 16 will be rotated just enough to permitthe coin to drop fully into the pocket, as shown in Fig. 5, and this movementof the coin will carry it partly under the end of the pawl so that if the finger-hold upon the door 5'be released the weight of the door will carry it downwardly and the wheel 10 will be rotated, the rotation being transmitted through the shaft 12 to the disk 16 and the coin being carried under and past the pawl to permit the free end of the pawl to again drop onto the periphery of the disk, as shown in Fig. 6. r The rotation of the wheel 10 and e the disk 16 will continue until a succeeding stop shoulder 19 on the disk is brought against the end of the pawl, whereupon the arts will be held at rest in the position shown 1n Fig. 1. The distances between successive shoulders 19 on the disk 16 will correspond to the heights of the compartments in the column so thateach operation ofthe disk and wheel will permit door 5 to descend and fully uncover the end of one compartment and only one compartment. Any attempt to juggle the movements of the door by manipulation of the same to impart retrograde movement thereto and thereby possibly free the door for uncovering two compartments will be frustrated by the engagement of the dog 23 with the notches 8 ofthe door, the point 24 of the dog passing through an opening 28 in theflange 6 to engage the notches 8 of the closure, as shown clearly in Fig. 4. When all of the compartments have been exposed and restocking of the same is desired, the fresh merchandise may be inserted in the compartments through the exposed free ends of the same but to permit the closure to be returned to its 7 Then by gripping the flange or finger-hold 27,

the door may be raised to its initial position, the shoulders 19 of the pocket disk 16 riding under the pawl 20 in an obvious manner.

- The mechanism of the present invention is exceedin 1y simple and compact and may be veryrea ily produced and installed at a low cost." It w1ll be noted that the toothed wheel and the pocket disk as well as the arts cooperating therewith are all carrie by the face late 13, and the casin sa'id ace plate and the sidep ates 14; may be assembled with the moving elements and then secured over the front of the column within the. cabinet. The very few partsnecessary to consisting of produce the'mechanism makes for economy in construction and minimizes the liability of the mechanismto get out of order and need attention. I

Having thus described the invention, I claim a I 1. In a vending machine including a column of compartments and a vertically movable closurecommon to all the compartments, an escapement wheel engaged, with the closure and adapted to be rotated byv the weight of the closure, a pocket disk connected with said escapement wheel to rotate therewith and arranged to receive a deposited coin when partly rotated by a slight lifting of the closure, and means engaged with the disk to prevent rotation of the same and the escapement wheel, the last-mentioned means being arranged to be engaged and released by a coin received and held in a pocket of the, disk.

2. In a vending machine including a column of compartments and a vertically movable closurecommon to allthe compartments, the combination of an escapement. wheelengaged with the closure and adapted to be operated by the weight thereof, a disk having a series'of peripheral pockets and stop shoulders arranged adjacent the respective p0ckets, and a pawl adapted to engage the stop shoulders and thereby hold the disk and the escapement wheel against rotation, the pockets being adapted to receive a coin and initially support the same against the pawl whereby a slight lifting of the closure will effect. a partial rotation of the disk in one direction permitting the coin to fully enter a pocket whereupon reversal of the movement of the disk will freethe pawl and permit rotation of the disk and the escapement wheel and descent of the closure.

7 same and prevent upward movement thereof,

3. In a vending machine including a 001-.

umn of compartments and a vertically movable closure common to all'the compartments, the combination of a flange on the closure having equi-distant openings therein, an escapement wheel mounted adjacent the-closure and adapted to engage the openings in said flange, a diskmounted coa-Xiallywith the escapement wheel and connected therewith, said disk having peripheral stop shoulders and being providedyon one side with shallow pockets each having one terminal adjacent a stop shoulder and at its opposite terminal flared away from the stop shoulder,

V and a pawl mounted adjacent the disk and having its free end riding on the periphery of the disk whereby a coin may be momentarilyarrested by the end of the pawl and the ab rupt side of the pocket, whereby a slight lifting of the closure will effect a partial movement of the disk in one direction permitting the coin to fully enter the pocket and a reversefmovement ofthe disk causingthe coin 'to ride under and release the pawl.

, 4:. In a vending machine including a column of compartments and a vertically rmov-.

able closure common to all said compartments, coin-controlled means for effecting a step by step descent of the closure, a dog mounted adjacent the closure to engage the a support for said dog having a notch in its 7 upper portion, anda latch pivoted to the dog and adapted to seat in said notch to release the dog and permit upward movement of the closure. 8

In testimony whereof I aflix my signature. BENJAMIN L. FRY. [L; 5.]
