zitrolledk vending machines kfor confectionery vand other v'small articles. f
More especially the invention relates to vending machines suitable for placing where space is verylimited, as, for instance, in street cars, busses, railway cars, flying machines,
fshipsltheatres, cinemasy and the like. The
manner in which such small vending machines, which are distributed over a great number of points, must be inspected andsupvplied with the necessary articles, requires that thefillingof the machines be accomplished infaneconomica-l way, anda superr `vision by the` business mana-gement must be. kpossible in asimple and expeditious manner.
With thel vending machines of known yconstruction the filling-is accomplished aty the place where the machine is mountedk by an official' of the firm, who also collects the money from the machine; and since they are capable of being lled with a great quantity f of articles, their inspection and control'in the manner mentioned is possible. This mode of operation, however, has considerable disadvantages in case the machine isy constructed in suc-h a way that rit may contain only .a
ysmall, number of articles. `On the other hand, a great amount of time will berequired in order to fill themachines, which are lo- VHcated at a great many different places, and
f furthermore the control yof the money.k col- 'y tages, the coin-controlled vending machine .lected from the machines and the book-,keep f c ing andthe like for the articles which have been; sold are very difficult. In order to do away with these disadvanaccording to this invention is connected with a base plate which is permanently fixed at the placewhere the machine is to be located the f connection being effected in such a'manner that thefmachine may be [disconnected fromy i said plate by a simplel manipulation, after unlocking a lock, andrtaken off as a whole from the plate in order to be replacedby another machine which is yfilled lwith the articles@ Hence,- the improved machine need l Y i never be openedat its 'place of operation, but

cover of the machine andl the collection of the money contained therein, so that an exact .control of the same, as well as ofthe articles which still remian in the machine is made possible. The lmachine is vthereupon again lilled atthe central oflice, locked, and thereafter delivered to the officials who again Y kbring it back to its place of destination and lock it to the base plate provided for that purpose. In this way, a double control is obtained, since it is not necessary to give the officials, who fetch the machines with empty magazines and replace them by re-filled machines, the key which opens the machine proper. On the other hand, the opening and rrefilling of the machines and the collection of the money contents of the samey can be carried out eventually by other highly trusted oliicials in the presence of witnesses.
.In thecaccompanying drawings, an ex- -ample of the new coin-controlled vending Fig. 2 a perspective view of the cover plate, klooking .toward the inner face thereof; and Fig 3 is a front or face viewvof the base plate. e'
The casing '1 of the vending machine, which is preferably of cylindrical form, is provided with a frame 2 to contain the articles to be sold, one article,'such for instance as a .tablet 3 of chocolate, being shown as an ex-v ample. f a
The casing 1 is locked by the cover` 18,
, which engages the periphery ofthe former byits flanged rim 19. When the casing 1 is closed bythe cover 18, two stopbarsQO, 20
kwill engage the outer arms 21 of a pair of bayonet slots which are provided in the cylindrical outer wall of thecasing 1, and upon 7rotation will come into the inner or crossarms `22 (Fig. 1) arranged in angular relationfto the arms 21. The stop bars prefer.-
`ably consist of metal strips, theinner part l of each strip lying flat against the cover and being soldered thereto, while the outer part is bent outward and is adapted to cooperate with the corresponding bayonet slot. In this condition, the stop willbe locked by the bolt 23 of the upper lock 24 and the stop 20 by the bolt 25 of the lower lock 26, as soon as said bolts are brought into their lockin the center of the cover there is provided a slot or opening 28, which slots are designed for engagement by the pins 29, 29 and 30 on the base plate 31 (see Fig. 3)'. The pins`29,
'29" are recesseda-s indicatedat 32 and 32"v for coaction with the narrowv parts 33, 33" ofthe ykey-hole slots 27, 27 so that the removal of the cover 18 or of the casing 1 from the base plate 31 will be made impossible without first "placed uponthe easing l in such a manner that the-stop bar 2'0"w`ill drop intovthe arm 21 locking the cover 18-to the casing 1 andthat `Vthe lower lock 26 is designed forl'oclingthe rota-ting the cover or the casing in backward direction. By rotating the casing on the base plate 31 to engage the pins 29 and 29 with the slot parts 33, 33, respectively, andby locking the bolt' 23 then lying between stop `2O and pin 29 the engagement of said bolt with stopy 20 and pin 29 will prevent a back rotation of the casing relatively to 'the base plate, while the recesses 32 and v32" of the pins`29 and 29 will prevent the machine from being lifted from the plate. i
It will be understood that in case one of the locks is intended to lock the cover 18 to the casing 1, and the vother to lock the said -cover to the base plate 31, it is necessary that the key-hole slots 27 and 27", as well as the pins=29 and 29', be disposed dis'symmetrically with respect to thecentral vertical axis, as indi-cated iny Figs. 21and`3. y
Y lThe arrangement and operation of the lockh ing devices will be apparent from the following description ofthe manner in which the machine is made ready for service. lt is assumed that the` upper lock 24 is designed for cover and', consequently, the entire machine) -to the base'plate 31. It isal'so assumed that at the upper part ofthe casing the inner arm 212 vofy the bayonet `slot runs to Ytheright of f the outer arm 21, whereas at the lower part the inner arm 22 -runs to the left ofthe outer 55 arm 21. This arrangement is, of course,only, tobe regarded as an example. The magazine or frame 2 may, for instance, be convenientvlyiilled by placing the machine with: the
front side Adownupon 1a table. After the filling has been? completed, the cover 18 is of they upper bayonet slot and the stop bar 2O will' drop into the arm 21 of the lower slot.
Thecover- 18 isthenturned in clockwise `di- 'to the back plate and to lock Vit thereto. To this end, the machine isfplaced upon the base i lrection, whereupon the stop bars 20 and 20 will slide into the inner arms 22 of the-bay-V onetk slots and a connection will be established between the cover and the Casing. To secure this connection, the upper lock 24 is closed, 'l
whereby the bolt 23 is pushed across the edge of the stop bar 20 so that the cover cannot be turned in the opposite direction until the lock is opened. It should be noted that when the loch 24 is closed, the bolt 23 .will not block the space directly behind thekey-hole slot 27 because the entire slot is situated tothe left. 'Y
of the said bolt.y A
The cover having thus beenilocked to the casing, the next step is to attach the machine plate 31 in such a manner that the pins 29 and 29 in said plate are caused to enter thel wide parts y27 and 27 of the keyhole slots, while-at the same time the pin 30 will pass through the central opening 28 in the cover clockwise direction 'on thevbase-plate 31 to bring the pins into engagement with the narrow parts 33, 33 of the slots and by locking the bolt 25 of the lower lock 26, the machine will become firmly fixed tothe base plate 31. It will beunderstood that in the construction the lock 26 and the key-hole vslot 27 that when the pin 29 is situatedin the innermost corner 18. By now rotating thev casing in counter- Y Vv'here shownthere is such a'relation between Y of the narrowpart 33 of the slot-and'` the Vbolt *V i 25 is brought into locking position, Vthen the said bolt will substantially block the open space behind the said slot and thereby pref vent vbackward rotation of the casing relatively to the base plate, while the recesses 32 Y and -32 of'thepins 29 and 29, as already men- I ticned', will preventthe machine from being lifted olf' the plate.' y y Y It will be understood that in this way the machine is firmly fixed on the base plate,
which latter is itself fixed lat a desired place ifor instance on a'wall or on the back lof a chair, etc., by means of screws passed through screw-holes 34 in said plate; `the-screws bei-ng renderedv inaccessible by the machine when mounted, so that at the same time therekmoval of the base plate together vwith the vending machine fixed thereon isprevented.
