This invention'relates to coin-controlled *vend- 'ing' machines and more particularly to coin- "freed latch'control for permitting the operation of only one of a plurality of preselected doors.
Another objectof this invention'is to provide in a self-help vending machine consisting of a plurality of normally closed doors, of coin-controlled latch -means interlockingly arranged so that one only of the doors may be opened for accessto a vended article upon the deposit of ving chutes (not shown), with the acceptance -asingle-coin. I 1
A further object of the present invention is to provide a novel latcheontrolmeans operable by the swinging actionof a handle lever when fashion, for releasing thelatch mechanism upon Other objects will appearhereinafter.
The invention consists in'the novel eombina- 'tion and arrangement of parts to be hereinafter described and claimed.
v The invention will-be best understood by ref 'erence to the accompanyingdrawings showing thepreferred form of construction, and in which:

, Fig. 7 is a fragmentaryperspective view of a .portionofthe front wall of the cabinet with the .inet l0 providing a plurality 10f articlestoring chambers II each of which is provided with .a hinged closure member l2v'having atranslucent the web 25 of the channel .24. V edge of each of the abutting slide bars is provertical movement with respect thereto.
chan'lber H may be viewed from the exterior of the cabinet.
The number of compartments provided in the cabinet is optional, it being one .of the several objects of this invention to provide a single coin chute which is common to all such compartments The front wall of .the cabinet 10 has .an aperture l4 formed therein through which coins may be deposited, such coin-s .gra'vitating through any one'of several wellwknown coin testopening of such chute terminating in the region above a coin-freed .mechanism [-5, so that ac- .ceptable coins. will be deposited in a slot 16 the latter is-grasped and pulled in door-opening 215 .formed in. a masterslide .l'l.
This master slide .l13is linkedby a bell crank I18, pivoted on a wall .of the cabinet ID as at l9, with its opposite leg 20 carrying a depending pin 2| which abuts the .free end of a horizontal slide bar 22 arranged forshifting movement in a guide bracket 23.
This invention contemplates a plurality of slide bars similar to the slide bar 22, there being one such slide bar for each vertical tier of article storing chambers l I.
Each vertical tier of chambers II has associated therewitha vertically arranged channel member 24 having one flange element thereof against the inner face of the front wall I0 of the cabinet and the web portion 25 thereof arranged to support mechanism now to be described.
As seen in Fig. 3, each of the slidebars 22 -is arranged in abutting relationship and is supported in the brackets 23 with one end portion thereof extending through a slot 26 formed in The leading vided with a notch formation 21 in alignment with the inside face of the web 25 so as to receive a tongue 28 formed on the lower end of a slide bar 29 having pin 30 and slot 3| arrangement on the inside face of the web 25 for Each of the vertically slidable bars 29 is urged by-spring means 32 into a normal position with the tongue portion 28 thereof out of engagement with the notch 2! in the horizontally slidable bar .22. Each of the slide bars 29 is linked to its corresponding slide bar 22 associated with the tier in which they are arranged, by means'of a dog leg or bell crank lever 33 pivotally arranged on a boss 34 carried on the inside face of the front wall ID of the cabinet. The lever 33 has its-horizontal leg disposed to-engage a.-lateral projection 35-carried by the slide '29 and has wall-l3 through which the articlesgstoredvinlthe .55
its vertically disposed :leg extending through :a
The upper end of the slide bar 29 carries a roller member 31 which is normally urged into a notch formation 38 formed in a plunger member 39 arranged for horizontal shifting movement between the flanges of the channel 24. plunger 39 has a laterally extending pin formation 40 disposed to be guided for sliding movement in an opening 41 formed in the front a handle 43 pivotally arranged as at 44 in trun nions 45 formed as a part of the casting which comprises the door structure l2.
The door l2 has formed integrally therewith a keeper hook 46 (Figs. 5, 6 and '7). This keeper hook 46 is arranged such that when the door is closed the keeper 46 will extend through an opening 41 formed in the front wall of the cabinet, with a notch formation 46 latchingly engaged by the nose 43 of a latch dog 49 pivotally arranged on the web 25 of the channel 24 as at 59; there being a. spring anchored to the channel as at 52 and having its opposite end connected to the free end of the latch dog 49 to urge the latter in a clockwise direction (Fig. 5).
The plunger 39 has, as already pointed out, a notch formation 38 which normally acts as a stop for the roller member 31 of the slide bars 29. One edge 38 of this notch 38 is disposed at an angle with respect to the horizontal and bears against the roller 31 in a manner such that when the handle 43 is grasped and pulled in door-opening fashion to rock the latter into dotted line position (Fig. 5), the cam formation 42 will be urged in a clockwise direction, the door being latched against opening, to depress the pin 40 and slide the plunger 39 to the right whereby the edge 38' will in camlike action urge the roller member and the slide bar 29 which carries the same downwardly against the action of the spring means 32 to rock the bell crank 33 in the manner heretofore described and effect movement of the horizontal slide bars 22 in the direction of the master coin slide H, as heretofore explained.
The plunger 39 likewise carries a second cam formation 53, the lower end of which is arranged to permit an initial movement of the plunger 39 whereby to shift the slide bars 29 and 22, and subsequent to such shifting movement this lower end of the cam formation 53 is adapted "to engage a pin 54 extending laterally from the latch dog 49 so that in the last phase of the horizontal movement of the plunger 39 the latch dog 49 will be urged counterclockwise against the action of its spring 5| to dispose the nose 48 out of latching engagement with the keeper member 46 on the door, whereupon the particular door will be free to swing into open condition ,as seen in Fig. '7.
As seen in Fig. 5, in view of Fig. 1, there may be a plurality of article containing compartments l I arranged in vertical alignment with respect to The from the spirit of the invention.
each other. For the purposes of explanation there have been but two such vertically arranged units shown, with the lowermost slide bar 29 providing a tongue formation 28 which will form an obstruction for all horizontal slide bars arranged on its side away from the master control slide l'I. Each of the vertical slide bars 29 arranged above this lowermost one will have its lowermost edge 29 formed with 2. depending lug 55 abutting the topmost edge of the lower slide bar 29. Such abutting arrangement of two slide bars provides a slot or notch 56 into which there may be disposed a laterally extending pin 51 carried by the adjacent plunger member 39. According to such construction, if the uppermost slide bar were depressed by operation of the handle as heretofore described, the depending lug 55 of the slide bar 29 would depress the next succeeding slide bar 29 downward, thus moving the notch or slot 56 formed between the two abutting slide bars 29, out of alignment with the laterally extending pin 51 on the adjacent plunger 39; thus, it is seen that operation of the lowermost plunger 39 would be blocked by reason of the lateral extension 51 thereof bearing against the side edge of the now depressed slide bar 29. Likewise, if the lowermost slide bar 29 alone were depressed by reason of operation of its handle 43 to shift the plunger 39 associated therewith inwardly, the lateral extension 57 carried by such moving plunger 39 would pass into the slot formation 56 provided between the two abutting slide bars 29 and obstruct the uppermost slide bar 29 against movement in a downward direction, thereby latching all door mechanisms above the particular one opened against operation.
Once the door to a particular compartment has been opened, the latch keeper 46 will be removed from latching engagement with the latch dog 49 and by reason thereof the door handle and door will be swung away from the front face ID of the cabinet, thereby freeing the plunger for movement into normal positionas shown, by action of the spring members 32 as well as like spring members 58 arranged with respect to the horizontally disposed slide bars 22 to return the latter toa normal position. That being the case, even though a compartment is vacated and the door thereto is left in an open condition, the remaining compartments are still capable of being operated upon the deposit of a coin in the manner heretofore described.
It istherefore seen that we have provided a coin-controlled latch mechanism which is effective for preventing simultaneous operation of any two of a plurality of latched doors upon the deposit of but a single coin in the coin chute.
It is likewise pointed out that we have provided a means whereby when a particular tier is operated upon the deposit of a coin, all other tiers will be prevented from operation, and further that we have provided a latch mechanism whereby access to article compartments disposed one above another may be hadonly one compartment at a time for the deposit of each individual coin. While we have illustrated and described the preferred form of construction for carrying our invention into effect, this is capable of variation We therefore do not wish to be limited to the precise details of construction set forth, but desire to avail ourselves of such variations and. modifications as come within the scope of the appended claims.
Having thus described our invention. what we claim as new and desire to protect by Letters Patent is:
