VENDING MACHINE.

Original application filed May 26, 1923, Serial No. 641,584. Divided and this application filed November 19, 1926. Serial No. 149,486.

This invention relates to coin controlling mechanism for vending machines and the like, and this applicationis a division of my co-pending application, Serial No. 641,584, led May 26, 1923, for vending machines.

The objects of the invention are to provide a simple and durable coin controlled mechanism which cannot be rendered operable by slugs or by coins of a denomination other than that which is intended to operate the machine; to provide such mechanism which cannot readily be manipulated by means of Wires or other devices so as to render the machine operable without insertion of a proper coin; to provide such mechanism which will consist mainly of stamped metal parts, such as can be economically manufactured, and in general, to provide an improved structure of the'class described.

Other objects and advantages of my invention will become apparent by reference to the following specification when considered in connection with the accompanying drawings illustrating a yselected embodiment thereof, and in which:

Fig. 10 is a detail plan view of part of the coin controlled mechanism, and

Fig. 11 is a detail front elevation of a part oit said mechanism.

Referring now to the drawings, I have shown my improved coin controlled mechanism applied to a machine particularly adapted to vending comparatively bulky articles such as sanitary napkins, and which machine comprises the main housing 15 and a receptacle 16 which is mounted thereover. The housing 15 contains the article dlscharging devices which in the present instance comprise a drum 17 which is secured to a shaft 65 and which is adapted to be rotated therewith. The drum 17 is provided with pins 18 which are for the purpose of entering the bottom side of the lowermost article in the receptacle 16 so as to force the said lowermost article from the receptacle as the drum is rotated. In Fig. 1, articles to be vended are indicated in dotted lines vat 19, and the receptacle 16 is. provided with suitable means for guiding the articles downwardly as the lowermost article is removed therefrom and also with a suitable cover indicated at 20 which may be hingedly connected to the body of the receptacle at its upper edge as indicated at 21, for permitting access to the interior thereof.

The above described apparatus forms no part of the present invention except as claimed in combination with other parts hereinafter described, for which reason a more detailed description will not be given here. Such a detailed description may be had by reference to my said co-pending application.

The coin controlled mechanism is adapted to prevent rotation of the article discharging drum 17 except when a proper coin is deposited in the coin slot which conveys the coin to the controlling mechanism where it is effective to render the discharge drum operable by means which I will now describe.

The coin-controlled apparatus is provided with a coin chute leading from a coin slot 5l in the vfront wall ofthe container. This chute is formed between vertical plates 52 and 53, the former being channeled.- The plate 52 is secured to the sidewall of the casing, as at 54;, and the plate 58 is attached -to the plate 52, as at 55. A magnet 56 is secured to the plate 52 with its operating ends forming a portion of the inner edge of the chute at the point where the chute turns abruptly downward so that each coin passing through the chute rolls or slides over these ends. The main chute is divided into two branches by the rib or partition 57 on the plate 52, the branch chute 58 leading to a coin ejection opening 59 in the casing and the branch 60 conducting the coin to the operating mechanism. 1 It an iron slug is inserted in the coin chute, it will be sufficiently attracted by the magnet 56 to cause it to drop into the branch chute 58 and be ejected from the casing Without rendering the discharge mechanism operative. @n the other hand, when a silver coin is placed in the coin slot it will not be attracted by the magnet and will drop vertically into the branch chute 60 leading to the operating mechanism. A proper coin, as 61, upon passing through the chute 60 is deposited in one of the pockets 62 formed between lugs 68 on the disk 64 fixed upon the propeller shaft 65. The coin is held in one of these pockets by a disk 66 parallel to the disk 64 and substantially contacting with the outer faces of the lugs 68. The disk 66 is secured to a collar 67 upon a sleeve 68 free upon the shaft 65 and is provided with peripheral flanges or lugs 69 bent toward the disk 64. An operating handle or lever 70 is secured upon the sleeve 68. When a coin enters one of the pockets 62, rotation of the lever 70 produces a corresponding rotation of the disk 66. This rotation of the lever 70 brings one of the lugs 69 into engagement with the coin and causes the disk 66 to operate the propeller shaft 65 through the medium of the coin and the disk 64. The periphery of the disk 64 is provided with equally spaced notches forming teeth 71, one of these notches normally containing; the operative end of a springpressed detent- 72 free upon the short shaft 73 supported in a bearing in the plate 52. The initial advance of the coin by the rotation. of the lever 70 in counter-clockwise direction (Fig. 8) brings the coin into engagement with this detent and causes the same to he raised before the detent comes into engagement with the tooth 71 at the end of the notch.

A ratchet wheel 7 4 is fixed upon the revoluble propeller shaft 65 and engaged by a spring pressed pawl 75 which prevents rotation of the shaft in reverse or clockwise direction. The pawl 75 is mounted on the pivot pin 76 inthe plate 52. A lobed cam 77 is like-- wise secured upon the shaft at an interval from the ratchet wheel 74. This cam operates rollers 78 and 79 respectively, carried by levers 80 and 81 mounted intermediate their ends on the short shaft 82 supported in a bearing in the plate 52. The lever 80 is loose upon the shaft 82 while the lever 81 is lixed thereon.. At the outer end of the shaft 82 is fastened a dctent 83 which is normally in position to engage a tooth 84 on the periphery of the disk 66 to normally prevent full forward rotation of this disk. The detent 83 and cooperative portion of the tooth 84 are, however, spaced apart a distance suliicient to permit limited forward movement of the lever 70 and disk 66 for a purpose which will presently appear.

Then a proper coin is within one of the pockets 62, is serves, as previously explained, to connect the disks 64 and 66 by engaging the adjacent edges of the lugs 69 on the disk 66. initial forward rotation of the lever 70 immediately causes the detent 72 to be disengaged from the tooth 71 and the shaft 65, and lobed cam 77 may be accordingly rotated. Rotation of the cam 77 is effective to lift the detent 83 before the disk 66 has rotated sufficiently to bring the tooth 84 into engagement with this detent and therefore the rotation of tl e disk 66 may continue. This lifting of the detent is accomplished by the abruptlobe of the cam quickly forcing the roller 79 away from the axis of the shaft 65. ln Fig. 8 is illustrated the normal or initial positions of the cam, roller and lever. Fig. 9 illustrates the relative position of these parts after the rotation of the shaft 65 has commenced. The roller 79 is riding out upon the lobe of the cam and the lever 81 has previously rotated the shaft 82 su'liiciently to move the detent 83 out of position to engage the tooth 84. The initial positions of the disk 66 and detent 83 are illustrated in Fig. 6. The corresponding ends of the levers 80 and 81 are connected by a spring 90. The roller 78 leads the roller 79 by one lobe distance and aids in retaining it firmly against the periphery of the cam. As soon as the propelling handle or lever 7 O has advanced its full distance and is released by the operator. a spring 91 causes this lever, the sleeve 68 and disk 66 to be returned to their initial position. The travel of the lever 76 is determined by suitable stop lugs on the side wall of the casing, one of which is shown at 92. This lever 7 0 is shown in its initial position in Fig. 1 of the drawings and when operated is adapted to be moved towards the front of the machine.

As soon as the lever 7 0 is released at the tern'iination of its advance, the coin drops from the pocket in the disk 64 into a coin box 94. This coin box is pivotally mounted on the rod 95 supported by inwardly project-- ing lugs 96 on the side wall of the casing and the outer wall ofthe box forms in closed position a portion of this wall of the housing or casing. The coin box is normally held in closed position by a spring actuated latch 98 which enters a slit 99 in the side wall of the box. l/Vhen the casing is opened the collector may open the coin box by inserting his finger through the opening 100 in an inner Wall 101 of the casing` and pressing upwardly on the inwardly bent upper end 102 of the latch. The coin box is shown in open position in dotted lines in Fig. l. moved to closed position, the latch is forced into the slit 99 by the spring 1.04. The coin box cannot be opened from the outside of the casing.

I find it desirable to provide means for preventing insertion of a coin in the machine when the supply of articles therein is exhausted. For this purpose, I provide a wire which is slidably mounted in suitable bearings, as clearly shown in Fig. 2, and which is provided with a portion adapted to lll() As soon as the box is enter the slot as indicated at 116 in Fig. 2 to partially close the coin chute so that a coin cannot be inserted therein. The wire 115 rests at its lower end onv one arm 117 of a detector member 118 which comprises the said arm 117 and a finger 119. The member 118 is pivotally mounted on the said shaft 73 and the linger 119 is adapted to enter a passageway 120 (Fig. l) through which the articles are propelled as they are discharged from the machine. The passageway 120 is disposed across the front of the drum 17 and is adapted to convey the articles from the receptacle 16 to a delivery shelf 121 at the lower end of the machine.

In the present embodiment of the vending machine, I discharge one article for each quarter revolution of the drum 17. It will be seen by inspection of Figs. 1 and 2 that a quarter of a revolution of the drum 17 will be sufficient only to propel one ofthe articles from the receptacle 16 to a position immediately infront of the drum as indicated at B in Fig. 1. In order to discharge the article from the position indicated in F ig. 4r, it is necessary to turn a drum through substantially another' quarter revolution so as to propel the article downwardly in the passageway 120 to a pointwhere it will enter the delivery shelf 121 from which the purchaser may withdraw it.

It will be apparent that there will at all times be an article in the position indicated at B in Fig. 1, which article will be effective to force the finger 119 inwardly, thereby rocking the member 118 on its pivot, and swinging the arm 117 upwardly whereby the wire' 115 is maintained in raised position as shown in Fig. 2. It will further be obvious that when the last article has been discharged from the B position, the finger 119 will enter the passageway 120, permitting` the arm 117 to swing downwardly and whereby the wire 115 is lowered to close the coin chute at 116 as above explained. In order to insure downward movement of the wire 115, I provide a suitable spring 122 suit-ably anchored on a stationary part of the mechanism and having its free end engaging a portion ofthe wire as clearly shown in Fig. 2. f

From the foregoing description, it will be evident that my improved coin-controlling nnchanism will prevent the yuse of slugs instead of proper coins for the opera-tion of the machine. Iron slugs,such as are often used for pilfering machines of this type are side tracked by means of the magnet 56 and are ected without effecting operation of the machine. A slug of smaller diameter than the coin which it is intended to use in the present embodiment will not be effective to operate the machine since it will pass between the lugs 63 and therefore will not act as a connecting element, which is necessary for operation of the machine. The ratchet construction prevthe operative direction.

vents rotation of the article discharging mechanism in the reverse direction and separate and distinct detents normally prevent rotation of the driving and driven disks in It` will further be noted that both of these detents must be dis- `engaged in order to render the machine operable by the handle provided for that purpose, and that the detent 72 prevents independent operation of the discharging drum by means of a wire hook or other similar contrivance which might be inserted through the discharge opening and caused to engage the drum or some part connected thereto. The coin performs the double function of disengaging a detent, and forming the operative connection between the driving and driven disks.

I am aware that many changes in the construction and arrangement of parts may be made without departing from the spirit of my invention as defined by the following claims which I desire to have construed as broadly as possible consistent with the state of the art, and while the term disk has been employed throughout the specification and claims, it is to be understood that this is` not to be construed as a term of limitation, but is to be construed broadly to mean either a complete disk, a segment, or any portion of a disk.
