2. Claims. (Cl. 214'59) This inv'entionrel'ates in general'toamerchandise'vending machine of coin-controlled type; themachine being especially designed-but not limited-for dispensing merchandise, such ascube ice, inbags or the like. Each separate quantity of the merchandise and the retaining meanstherefor is hereinafter referred to as a merchandise unit.
In particular, this invention is directed to, and it is a major object to provide, a gravity-fed vending machine wherein a plurality of merchandise unitsare trolley suspended in a row from an inclined rail; the lead trolley normally being engaged by a movable stop, and coincontrolled means is included to move the stop in a manner to permit said lead trolley and the merchandise-unit suspended therefrom to run forward on the rail to a discharge point, at'which said merchandise-unit is automaticall'y released from the trolley-and drops into a dispensing areaa Another important object ofthe invention is to prov ide' 'a vending machine, as above, wherein each trolley includes a novel releasable clamp which engages the corresponding merchandise unit and normally. holds the same in suspension fromf such trolley; there being instrumentalities arranged to' automatically 'release' such clainp' upon each trolley reaching said-discharge point.
An additional object of'the inventionis to 'prov'ide'a vending machine, as i'nthe preceding paragraph, wherein the rail is formed with a relatively sharpdropcff at the discharge point, and an instrumentality" is mounted adjacentsuch point -for engagement by an elementof-the clamp whereby 'toreleasethe latter as'ea'ch trolley reaches andtraverses such drop-01f.
A separate object ofthe-invenion is to provide a novel railextension, beyond such drop-off, arranged to carry each empty trolley to a point clear of the dispensing area and to then deliver such trolley into a receiving container for subsequent "re-use. I
A further object of the invention is to provide the vending machine with a noveldispensing chute and :access door assembly; the chute being disposed to receive each merchandise unit as it is releasedjand' drops from atrolley, and the accessdoor being unlat ched' by the weight of the merchandise unit resting onthe floor of said chute.
A still further object of the invention is to provide a vending machine which has substantial capacity and yet compact, permitting a number of the vending machine assemblies to be mountedin a conventional walk+in type dispensing box which" an operator enters. to load said assemblies.
It is also an object of the invention to provide. a vending machine, for the purpose, which is relatively simple in structure, and designed for ease and. economy of manufacture, andlong service with a minimum of maintenance or repair.
Still another object of the invention. is to provide a practical, reliable, and durable vending machine, and
one which will be, exceedingly. efiective for the purpose for which it is designed:
These objects are accomplished by means of such structure and relative arrangement of parts, as willfully appear by a, perusal of the following specification and claims.

Referring now moreparticularlyto the drawings and to the characters of reference marked the'reon, theinven- 'tion is here illustrated ina dual rail vending machine assembly; i; e., one wherein two separate vending mechanisms deliver toa commondispensing area so that merchandise" unitsuoftwosizes or kinds may be accommodated by such assembly.
Such'vending machine assembly is mounted ina walkin type dispensing. box, indicated generally at 1', and into which the public does not have access; As is conventional, such type of dispensing boxis provided .with a locked :door (not shown), but by means of which an operator gains access into such box for the purpose of loading the vendingnassembly or otherwise servicing the equipment. f
The. vending machine assembly, as here illustrated, comprises a pair of'elongated, transversely spaced rails 2 mounted, in parallel, at a forward, downward, and relatively slow incline toward but terminating short of the front 3-of the box I, such rail's being disposed at their forward or-terr'ninal endsinthe upper portion of a dispensing area, indicated generallynat 4.
The rails 2, each with one flange vertical and unobstructed on the outside, and the other flange projecting laterally inwardly, are supported from and above the' floor 5 of box 1 by 'a frame, indicated generally at 6; such frame including, at the front, a central post 7 which carriesa cross bar- 8- spanning between, and secured to, the rails 2.
The dispensing area 4, which lies directly inwardly from the front 3 of the box l, is-defined-at the bottom by a merchandise unit receiving chute, indicated gen- .A longitudinal row of such trolleys rides the related rail 2, and each trolley comprises a vertical hanger 11 disposed laterally out from the vertical flange of the rail. At its upper end each hanger 11 is fitted with a laterally inwardly projecting spindle 12 having a grooved roller 13 thereon, and which roller engages and rides the upper edge 14 of the vertical flange of the rail.
The hangers 11 are each of a length to depend a distance below the rail, and at the lower end portion each hanger is fitted, on the inside, with a releasable clamp, indicated generally at 15. Each such clamp comprises a bracket 16 secured to the hanger 11 on the inside, and a depending laterally swingable link 17 is pivoted at its upper end, as at 18, to the bracket 16. The depending link 17, which is disposed inwardly a distance from the lower portion of each hanger 11, is fitted at its lower end with a laterally outwardly and upwardly inclined, movable jaw 19 of substantial transverse width; such jaw 19-at its outer edgenormally cooperating in overlapping relation with a downwardly and inwardly inclined fixed jaw 20 on the lower end of the hanger 11. The fixed jaw 20 is relatively short transversely.
A clamp actuating finger 21 projects laterally inwardly with respect to, and intermediate the ends of, the depending link 17, and said finger 21 is formed, at its inner end portion, with a fork 22 which straddles such link 17. At its inner end the fork 22 is pivoted, as at 23, in connection with the bracket 16 for vertical swinging movement of said finger 21.
Toggle links 24 pivotally connect at one end to the link 17 intermediate its ends, as at 25; such toggle links thence extending lengthwise of the legs of the fork 22 and pivotally connecting thereto, as at 26.
With such arrangement of each clamp 15, upward swinging of the finger 21causes opening of the clamp; i. e. retraction of the movable jaw 19 from the fixed jaw 20. Conversely, when the finger 21 is swung downwardly the clamp 15 closes; i. e., the movable jaw 19 moves toward and then laps the fixed jaw 20. In this latter or closed position of the clamp 15, the finger 21-by reason of the assembly of link 17 and toggle links 24passes slightly below dead-center, locking the clamp 15 against accidental release.
Each of the row of trolleys supported from the related rail 2 suspends a merchandise unit below such rail; the merchandise units here being illustrated as bags 27 whose closed necks 28 are each gripped by the closed clamp of the related trolley. The bags 27 each contain a predetermined quantity of the merchandise-such as cube iceto be dispensed.
The bags 27, with the predetermined quantity of merchandise therein, engage-4n face to face relation in a row, and the front to rear thickness of such bags maintains the trolleys 10 inspaced relation along the related rail 2 (see Fig. l).
The row of trolleys 10, and the loaded bags 27 suspended therefrom, are normally maintained against gravitational advance on such rail by a retractible, stop-formlng plunger 29 which slidably projects through the vertical flange of the rail 2 at a point immediately ahead of the lead trolley 10.
The stop-forming plunger 29 is an included part of a solenoid 30 suitably mounted in a transverse housing 31 which spans between and is supported by the bottom flanges of the two rails 2 of the vending machine assembly.
Each solenoid 30, for a dispensing operation, is controlled from a coin box 32 mounted exteriorly on the front 3 of the dispensing box 1, and such coin box 32 includes a coin reception slot 33.
Upon deposit of a coin (or coins) of predetermined value in the slot 33, the coin box 32, and associated mechanism, functionsthrough the medium of a control circuit whose cable is indicated in part at 34to cause actuation of the corresponding solenoid 30.
Upon actuation of the solenoid 30 the plunger 29 retracts and the lead trolley 10 is released to advance on the related rail 2. The actuation of the solenoid 30 continues only a sutficient time for the lead trolley 10 to be released and advance clear of the plunger 29; the solenoid 30 being deenergized and the plunger 29 returning to a stop position in suflicient time to engage the next following trolley 19. Of course all of the trolleys 10, and the suspended bags 27, advance one step upon the lead trolley and its bag being released from the stop forming plunger 29.
After the lead trolley 10 is released from the stop forming plunger 29, such trolley-by gravitytravels forwardly (see Fig. 7), and at the front end of the related rail 2 runs down a relatively fast inclined drop-off 35 (see Figs. 6 and 8), which results in relatively forceful downward movement of such trolley under the weight of the suspended bag 27 and the load of merchandise .therein.
When this occurs the finger 21 lowers rapidly, strikes, and is moved relatively upwardly by a horizontal trigger .plate 36 mounted, parallel to the forward portion of rail 2, in a fixed position in a plane below but laterally inwardly of such drop-off 35. Upon the finger being so moved relatively upwardly, the clamp is automatically opened, whereupon the suspended bag 27 is released in the dispensing area 4 and falls into the chute 9.
The trigger plate 36 is supported by an inverted L- shaped bracket 37 which is fixed to, and extends laterally from, the rail. The bracket 37 connects with the inner edge of such trigger plate 36 so that the finger 21 may move, without obstruction, to a position over such trigger plate as the lead trolley 10 advances to the start of the drop-off 35.
After the lead trolley 10 traverses the drop-off 35, with release of the suspended bag 27 as above described, the empty trolley is received on a carry-off rod 38 which projects forwardly from the lower end of said drop-off at a downward incline, and with a lateral curve. The length of the carry-off rod 38 is such that its free end extends to a point laterally of the chute 9. The empty trolley runs down the carry-01f rod 38, and at such free end thereof drops into a receiving box 39 set on the floor 5 to one side of said chute. In this way the empty trolleys are accumulated in the receiving box 39 for subsequent reuse.
In order to properly guide each lead trolley as it traverses the drop-ofi 35 and is received on the carry-01f rod 38, a longitudinal guide rod 40 is disposed in adjacent but spaced relation laterally out from the forward portion of the rail 2 and the inner end portion of said carry-off rod 38; the guide rod 40 being supported by an inverted U-shaped bracket 41 which is secured to the bottom flange of the rail and spans the vertical flange in clearance relation, whereby to not obstruct passage of each trolley (see particularly Fig. 6).
While the foregoing description has dealt in the main with the structure and operation of one of the separate vending mechanisms, they exist in the vending machine assembly in duplicate, as hereinbefore indicated; each mechanism however dispensing the merchandise unitshere the loaded bags 27one at a time at the dispensing area 4 and into the chute 9.
With dual vending mechanisms, one may be used to dispense a loaded bag of one weight, and the other to dispense a loaded bag of another weight, as illustrated in Fig. 3. Alternatively, one of the vending mechanisms could be used to dispense one type of merchandise and the other to dispense another type.
The chute 9, which is disposed in a well 42 in the floor 5, includes sides 43 and a floor 44; said floor 44 inclining forwardly and downwardly from the rear end of said chute. The chute 9 is pivoted on a rear, transverse axis, as at 45, for limited downward swinging movement, which movement is yieldably resisted by one or more compression springs 46 engaged between the forward portion of the floor 44 and a rigid mounting member 47.
The chute 9 is open at the front, and immediately ahead thereof the dispensing box 1 is provided with an access door 48 hinged at its upper end, as at 49, for upward and outward swinging movement to open. On the outside thereof and adjacent the bottom the door is fitted with a handle 50.
On its back side and adjacent but short of the bottom the door 48 is provided with a cam closing latch 51 which projects downwardly and normally engages in a receiving opening 52 in the floor 44 adjacent its front edge.
When a loaded bag 27 is released from the lead trolley 10 in the dispensing area 4 and falls into the chute 9, as hereinbefore described, the weight of such bag, resting on the chute floor 44, causes the same to yield downwardly against the compression of the spring 46; the movement being suflicient to remove the latch 51 from the opening 52.
Thereupon, the customer may grasp the handle 50 and swing the access door 48 outwardly and upwardly to open the same. With the door open, the customer reaches into the chute 9 and manually removes the loaded bag 27 resting on the chute floor 44.
After the loaded bag or other merchandise unit is so withdrawn the customer merely releases the handle 50, whereupon the door 48 swings closed and the latch 51 automatically re-engages in the opening 52 of the chute floor 44; this for the reason that such floor raises to its initial or starting position the moment that the loaded bag or other merchandise unit is removed therefrom.
To assure that the door 48 has sufficient momentum to cause engagement of the latch 51 in the opening 52 the handle may be relatively heavy.
As the described vending machine assembly is of limited height, another such assembly may be mounted thereabove in the box 1; the chute of the uppermost assembly being shown in part at 53. In this manner, the capacity of the vending machine may be doubled with respect to the floor area occupied, while providing for the dispensing of merchandise units of different weights or kinds.
From the foregoing description it will be readily seen that there has been produced such a device as will substantially fulfill the objects of the invention, as set forth herein.
While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not make a departure from the spirit of the inven tion, as defined by the appended claims.
Having thus described the invention, the following is claimed as new and useful, and upon which Letters Patent are desired:
