CAMPBELL K. DASHER ATTOR EY United States Patent 3,140,798 VENDING MACHINE APPARATUS Campbell K. Dasher, Box 1248, Station A, Marietta, Ga.,

assignor of fifty percent to Philip J. Malonson, Marietta, Ga.

Filed June 1, 1961, Ser. No. 114,138 9 Claims. (Cl. 221--89) This invention relates to a vending machine apparatus, and particularly to the sort of vending machine apparatus for vending soft goods such as bags of merchandise and the like, and especially to the portion of the vending machine which retains and releases the soft goods to be dispensed in sequence from the vending machine.

Vending machines are used now to dispense a multiplicity of different items, including a large selection of so-called soft goods. Typical soft goods are the bags of potato chips, snack foods, socks, handkerchiefs, and the like, which are packaged in soft, lightweight plastic or cellophane containers. A considerable number of hard goods have become soft goods for vending mach ne purposes because it is now being packaged in attractive bags made from sheet material. This type of vending is replete with special problems not present in the vending of hard goods, such as candy bars and the like, since the weight of the present mechandise is usually insufficient to accomplish a good gravity drop and the bulk and configuration of the package causes jamming in the machine as well as jamming between the successive layers of packages. Needless to say, it is extremely aggravating to a customer not to receive the merchandise after depositing his money, which is what happens in some vending machines when one bag catches on another.

The present invention is directed toward that portion of the vending machine which retains so-called soft goods in place in successive stacks or layers or other arrangement and selectively releases them in response to a control member operated on the machine by the customer following the depositing of the money therein. It is to be understood that the coin receiving and examining mechanism of a machine does not per se form a part of this invention, since any mechanism which receives and inspects and approves a coin and releases the control mem her is satisfactory for use with the present device. The present device operates from any movable control member which is pushed or pulled or turned or otherwise moved to cause a stroke or movement in the present apparatus.

Generally described, without restriction on the scope of my invention as defined in the appended claims, the present device comprises a panel which is adapted to fonm a part of a closed vending machine and which may be one of many identical panels arranged in the same machine. Each panel is adapted to retain in vertical clamped and overlapping relation a plurality of bags or the like containing merchandise to be dispensed one-at-atime in succession. The panel comprises a vertical panel plate constructed from sheet metal or the like, having a longitudinal and central vertical groove or channel formed in the middle thereof extending the full length, substantially, of the panel from bottom to top. A pair of inwardly turned plate members positioned adjacent the open channel provides a vertical track running substantially coextensive with the open channel or groove. The front of the panel is that part which contains the merchandise and has arranged thereon on opposite sides thereof in vertical alignment a plurality of spring-biased clamps comprising U-shaped clamp members with the inward portions thereof protruding into the open channel. The back of the panel has movably mounted thereon a vertically shiftable rack located adjacent one side of the open channel. A bag clamp tripping mechanism positioned for sliding movement in said track has a pivoted pawl member thereon with a tooth engaging successively with the teeth of said rack and said tripping mechanism having an inwardly protruding cam therein adapted to engage each of the bag clamps in succession to lift same to release the merchandise clamped thereunder. Each clamp rotates upwardly a slight amount in releasing its merchandise, thereby engaging the underside of the merchandise thereabove, lifting same out of the way.

A primary feature of this invention resides in an arrangement in a vending machine for so-called sof packaged goods and the like of a plurality of merchandise panels each adapted to retain merchandise for dispensing and each panel being readily removable from the machine for loading.

Another object of this invention is to provide a vending machine apparatus having a plurality of merchandise clamps thereon adapted to be engaged and released in succession.

A further object of this invention resides in the particular arrangement defined in the preceding paragraph and including an off-set portion on each of said bag or merchandise clamping devices which engages the merchandise thereabove to lift same out of the way each time the machine is operated.

Another object of this invention resides in the arrangement of a succession of merchandise clamps having the inner ends thereof protruding into a space through which there passes in succession an operating member which lifts each bag or merchandise clamp in succession, whereby a plurality of merchandise clamps may be arranged on a comparatively small panel member.

An additional object of this invention resides in the aforementioned construction and including a rack and pawl operating mechanism which is positive in operation and direction and which engages a merchandise clamp in succession to cause displacement of the clamp sufficiently to clear the clamped merchandise therein and including as an additional provision the lifting of the merchandise thereabove so as to clear the merchandise being dispensed.

A further object of this invention resides in the construction of the dispensing panel of the present vending apparatus whereby each merchandise retaining member remains firmly biased in place during the operation of the one merchandise retaining member being actuated so that there is less possibility of a mal-function resulting in the dispensing of more than one package of merchandise.

Other and further objects and advantages of my invention will become apparent upon reading the following specification, taken in conjunction with the accompanying drawings, wherein:

FIG. 1 is a front elevation view of a typical vending machine cabinet having a portion thereof broken away to expose a typical panel of the present invention.

FIG. 2 is a front elevation view of a panel constructed in accordance with the present invention with an intermediate portion thereof broken away and showing the merchandise retaining means thereon.

FIG. 3 is a back elevation view of the panel shown in FIG. 2 also with portions thereof broken away.

FIG. 4 is an enlarged side elevation view of a portion of the panel shown in FIG. 2 with typical merchandise shown diagrammatically thereon.

FIG. 5 is an elevation view in enlarged detail of some of the clamping members shown in FIG. 2.

FIG. 6 is a perspective view of a portion of the panel mounting.

As mentioned in the introductory material, the present invention is directed primarily to that portion of a vending machine which retains and releases the merchandise and is not concerned except incidentally with that part of the machine which receives the coin, inspects same and releases the operating mechanism. In addition, the present invention does not contemplate any specific type of operating mechanism, it being'required only that there be some shifting member which is operated for a limited distance to cause the transfer of power to the present device. Therefore, the operating mechanism is shown only diagrammatically or incidentally in the present invention, it being understood that any one of the many conventional mechanisms now known in the vending art can be incorporated with the present invention.

The vending machine It) in FIG. 1 comprises a closed cabinet member 12 having a dispenser opening door 14 thereon through which the merchandise is removed following the release thereof and having a typical normally locked merchandise loading door 16 mounted on hinges 17 through which typical soft bags 18 of any type of merchandise such as potato chips, stockings, jewelry and the like is contained for dispensing from the machine through door 14. A coin slot 20 receives the proper coin therein and releases typical mechanism for the actuation of the machine. Merchandise release and actuating handles 22 are positioned for limited movement on the front of the machine below transparent panel members 24 displaying the bags 18 of merchandise. in accordance with the typical operation of these machines, the customer deposits the correct amount of money in the slot 20 and pauses momentarily while the coin is inspected and then pulls the merchandise release member 22, moving same from the machine a slight amount. In FIG. 3, it is seen that each handle member 22 typically is normally retained for movement by a respective locking member 26, which is released by the coininspection and rejection mechanism to release an actuating member 28 connected to handle 22, thereby pulling and rocking a cam actuating plate 363 to cause actuation and Vertical movement of the notched portion 31 having a drive pin 32 located therein attached to a rack 64 to be described later on.

The readily removable merchandise panel of the present invention is designated generally by the reference numeral 34- and as seen readily in FIG. 1, is adapted to be removably positioned transversely or edgewise to the front of the machine so that a plurality of such panels 34 may be positioned in substantial parallel relationship across the width of the machine for ready removal for loading. Panels 34 are slidably mounted and retained in cabinet 12 on channel brackets 35 screwed on the machine frame.

Referring now to FIGS. 2 and 3 and the other figures of the drawings for a more complete understanding of the operation of panel 34, it is seen that panel 34 is constructed from flat, sheet metal or the like having a front 36 on which the merchandise is is normally positioned and having a back 38-which contains the actuating mechanism' for the merchandise release. An open groove or channel portion 40 is formed on the present panel 34 by inturning an edge 42 providing a pair of such opposed edges 42 facing each other across the opening id.

A plurality of merchandise clamping devices 44 are positioned for limited movement on the panel 34 and are arranged in the present embodiment in two columns of suchclarnps 44 spaced one above the other on opposite sides of the opening 40. Each clamp 44 comprises a central U-shaped body portion 46 extending and being pivotally supported in a pivot bracket 48 attached on panel 34 and having the terminal end on that side extended upwardly and thence inwardly into the face of the panel 34 in an aperture or opening 56. The other end of member 44 is spring-biased normally closed between a pair of lugs 52 by a spring 54 wrapped around the clamp member 44 and having one end attached thereto and the other end inserted into the panel. The end of the clamping device 44 is supported in the in-turned edge 42 and has an L -shaped portion extending into said channel. Each of the clamping devices 44 is normally spring-biased against the plate 36, thereby retaining bags 18 firmly in place pressed into and between the lugs 52. In the operation of the machine, starting at the bottom and moving to the top vertically, each of the clamping devices 44 is adapted to be shifted and moved out pivoting or rotation against the springs 54 through the action of a shifting mechanism or clamp actuating mechanism designated generally at 60, described in more detail.

As seen in FIG. 3, on the back 38 of panel 34 adjacent one side of the groove 40, there is positioned for limited vertical movement the shifting mechanism 60 comprising an elongated rack member 62 having aplurality of spaced rack teeth 64 therein arranged in vertical succession on the panel 34. The rack member 64 is adapted to operate flat against the surface of the plate upon which it is positioned and is held in place by a plurality of screws-66 positioned in elongated slots 68 formed on the rack 62. Retained in the opening 40 by means of a pair of track or guide members 70 is a clamp actuating member 72 having a pawl 74 pivoted thereon adaped to be engaged by one of the teeth 64 of rack 62. For purposes of loading the machine, the mechanism 72 has a finger plate 76 thereon upon which the thumb may rest while the hand grasps the lever of the pawl member 74 to move the entire mechanism '72 rapidly up the groove 40. With this arrangement, the mechanism 72 may be grasped by the hand and the pawl 74 depressed out of position and held in this position so that the entire mechanism '72 may be run up the slot to the top of the panel 34 and then back down again to load the clamping devices 44, each with a bag member 18.

A summary of the operation of the machine is as follows:

After the individual panels 34 are removed from the machine and loaded with bags or other merchandise 18, the clamp actuating apparatus 72 is returned to the lowermost position on the machine and remains there for the first operation. Upon release of the latch 26 and the actuation of the handle 22 and the lever 28 by the customer, the cam plate 30 is moved a limited amount which causes the pin 32 to be moved by plate 30 in notch 31 to move the rack 62 vertically a limited amount. The move ment of the rack 62 vertically causes the tooth 64 thereon to engage the pawl 74, thereby moving the entire clamp actuating mechanism 72 upwardly in the slot 40 engag ing the inward end of a lower-most clamping device 44 by a protruding actuating cam plate 78 fixedly mounted on the apparatus 72 and adapted to move the curved portion thereof against the inward end of the clamp 46. As the particular clamp 46 is moved rotationally in its support (see FIG. 4), it engages the bag 18 immediately thereabove, thereby lifting same a limited amount which prevents any engagement between the bag being released and that bag 18 thereabove. This overcomes one of the problems involved in some vending machines whereby the merchandise jams itself and dispenses nothing one time and two or more another time. The rack member 62 then drops to its initial position, placing the pawl 74 adjacent another tooth 64 ready for another operation. The pawl 74 moves vertically upwardly in the slot in this manner in sequence from one side to the other, actuating the respective clamps 46 as it moves to the top.

A particular advantage resides in the loading arrangement of the present machine. As described previously, panels 34 are removably and slidably supported in brackets 35, each panel 34 having its own set of brackets 34. The entire panel 34 may be completely removed from the machine 1t), placed on the floor or table or other place and loaded prior to re-inserting into the machine 10. V This is very important considering that a Serviceman must service many such machines as quickly as possible, sometimes in very crowded spaces under somewhat hectic circumstances. Each cam plate 30 and actuating member may be easily manually moved out of place for the purpose of removing the panel 38.

While I have shown and described a particular embodiment of my invention with suggested uses thereof and Q a prescribed mode of operation, this is by way of illustration and is not to be construed as any sort of 1imita tion on the invention since various alterations, changes, embodiments, deviations and eliminations may be made in the invention without departing from the scope thereof defined in the appended claims.
