Application April 3, 1953, Serial No. 346,635

2 Claims. (CI. 22.2-57.5

This invention relates generally to coin directing devices for coin-operated machines such as vending machines, telephone pay stations and similar equipment, and particularly pertains to a coin director adapted to normally retain coins inserted in the machine in a position from which they are released and guided either into coinrefunding means or into coin-retaining means within such equipment in payment of either a service rendered or merchandise delivered.

One of the major objects of the present invention is the provision of a coin director of a very simple andrelatively inexpensive construction, positive and dependable in its function, andwhich is easily operable and which will not in normal use get out of order, thus assuring continuous service over extended time periods.

Another object of this invention is the provision in a coin director of the type indicated of an extremely simple, effective and positively operable coin control device adapted to temporarily support deposited coins in a cen trol position, prior to their final disposition, that is either their return or their retention in payment for service rendered or merchandise received, and from which supported position the coins are accordingly directed into' either a coin-return chute or into a coin receptacle, and

which coin control comprises a sector of a cylinder having a cylindrical coin-supporting surface and two convergent coin-guiding surfaces, one of which being designed to direct the coins into the coin-return chute, the other surface being adapted to cause coins to drop into a coin retaining receptacle.

A further object of this invention is the provision in connection with the coin control of simple and effective electro-magnetically operated actuating means for the latter, also adjusting means for positioning the cylindrical coin-supporting surface of the device and balancing or localizing means for causing it to reassume a central position after each movement imparted thereto by said actuating means.

The foregoing and numerous other objects and important advantages of the present invention will become more fully understood from the ensuing description in conjunction with the accompanying drawings forming an important part of the present disclosure, but being adapted to serve primarily for explanatory purposes without in any way limiting this invention to the structural embodi ment illustrated, and wherein:

Fig. 7 is a fragmental enlarged horizontal cross section taken approximately along line 77 of Fig. 1.

As stated above, the coin director of the present invention is adapted for use in coin-controlled machines such as a merchandise vending machine, telephone pay stations and similar mechanisms in which it is necessary to provide a choice of the ultimately desired disposition of inserted coins, that is to cause the instrument to return or refund coins when either a service is not rendered or the purchase of merchandise is not intended, and to cause the retention of coins for services rendered or for a casing 11 which is preferably diecast and includes afunnel 12. The casing forms a one-piece hollow structure 13 with a removable cover 14. That hollow structure has, what may be termed a rear wall 15 (see Fig. 4), while cover 14 constitutes the front wall of the casing. Within funnel 12 there is provided at its lower reduced or bottom end a cylindrical bushing 16 with a cylindrically curved lower edge 17 (see Fig. 5).

Just below the bushing is operatively mounted a coin control in the form of a cylindrical segment 18 having an upper cylindrically curved portion 19, two radially disposedconverging side faces 20 and 21 and at least one end web 22 connecting the cylindrical portion 19 with the two converging faces 20 and 21.

At the juncture or apex of converging surfaces 20 and 21 there are provided pivots 23, 23' journaled in suitable aligned bearings arranged in casing rear wall 15 and cover 14, as can be clearly seen in Fig. 4, and operatively supporting coin control 18. From the frontal-end web 22 of the coin control there extends a pin 24 through an arcuate slot 25 of cover 14. Just below frontal pivot 23 of coin control 18, but distanced therefrom, there is attached to cover 14 a relatively large pin 26 pivotally supporting a two armed lever 27, pin 26 carrying a stop ring 26' defining the position of the lever, the latter having a relatively long upper arm 28 and a shorter lower arm 29. The upper end of longer arm 28 is bifurcated as at 30 for accommodating and operatively engaging pin24 of the coin control.

Short lever arm 29 projects through a slot provided in a connector or link 31 which operatively joins mobile armatures 32 and 33 of two solenoids 34 and 35 arranged in tandem fashion and symmetrically in respect to a.

vertical center plane passing through pivot pins 2.3, 23'

of the coin control and through fulcrum pin 26. for twoarmed lever 27. This lever is normally held in its central vertical position as shown in Fig. l and when thus positioned will maintain coin director 18 in its central position, that is in a position at which the smaller, reduced or bottom end of funnel 12 is closed by the cylindrical surface of the coin control.

Lever 27 is held in its central position by an arrangeand 39 for bars 36 and 37 are disposed symmetrically in respect to the above defined vertical central plane. Since pins 41 and 42 are biased by spring 4%) and are urged towards one another, they maintain lever 27 in its vertical central position. If for any reason there should arise thenecessity for a slightpositional change of the coin control so that the latters cylindrical surface 19 fully closes the bottom end of funnel 12, lever 27 is rendered adjustable and will effect ithG adjustment of the coin control. For the adjustment of lever 27 there is provided an. adjustable cam structure 43 consisting of a cam '44 in the form of a flange and an adjusting leg 45 for the cam, the leg having an enlarged slotted end 46. Cam flange 44 engages with its ends the adjacentcdges of bars 36 and 37 which are urged against one another by spring 40, see Fig. 7. Slotted end 46 of adjusting leg 45 is held in adjusted position by screw 47, see Figs. .1, 5 and 6. In Fig. 5 the degree of adjustment of lever 27 by cam structure 43 is exaggerated.

By consulting Figs. 1, 2, 3, 4 and 6, it will be observed that casing '11 is provided with a coin refunding chute 43, and that within the casing there are arranged two divergent coin-deflecting surfaces 49 and 50, and that above surface 49 there is pivotally suspended at 51 a coin abutment vane or coin guard 52 adapted to slow down the speed of released coins, thus preventing undue wear of the left end wall of the casing (see Figs. 1 and 2). Defiecting surfaces 49 and 5t) have a common joining ridge disposed just below the pivotal suspensions 23, 23 of the coin control.

Wiring In Fig. 1 there will be seen a schematical diagram of electric connections intended to facilitate the explanation ofthe operation of the present device. There are illustrated main supply leads 53 and 54, from which latter branchlead 55 extends to the mobile middle blade 56 of multiple contact switch 57, the latter having a pair of normally closed contacts and another normally open contact pair. Middle blade 56 is provided with upper and lower contacts, the upper contact normally engaging the contact of blade 58. From that blade a branch lead 59 extends to one terminal of solenoid 34, while from the other terminal a branch lead 60 passes to switch blade 61 of normally open two-contact switch 62 which, when the present device is installed in a vending machine, is operable manually by depressible button 63. The other blade 64 of switch 62 is connected with main lead 53.

From this main lead there extends a branch lead 65 to oneterrninal of solenoid 35, while from the other terminal of the solenoid a lead 66 is connected with the lower contact blade 67 of multiple contact switch 57. The contacts of blades 67 and 56 are normally separated, since mobile middle blade 56 is normally maintained in the position shown. That switch blade is intended to be automatically operated by actuating means 68, assumed to form a part of and being movable by a mechanism of either a vending machine, a telephone pay station or any other coin-operated device, after either merchandise is delivered or service is completed, respectively. In the application of the present device to a pay station, switch 62 is actuated automatically instead of manually when, for instance, no service is rendered and when the receiver is replaced to its non-operative position.

Operation Assuming that the device is employed in a merchandise vending machine, coins deposited in the machine will drop into funnel 12 where they are temporarily retained until the would-be purchaser decides to either obtain a desired article vended by the machine or to forego such purchase, in which latter event the coins inserted will be refunded to him when he closes switch 62 by depressing button 63 (see Fig. 1). By closing switch 62 solenoid 34 becomes energized and attracts armature 32, drawing it into the solenoid. This movement of the armature causes short end 29 of lever 27 to move in clockwise direction, thereby moving longer lever arm 23 also in clockwise direction. This movement of the lever swings coin control 18 to the right, indicated in broken lines in Fig. 6. At that position of the coin control the latters cylindrical 4 surface 19 clears the bottom end of funnel 12, thus releasing the coins to slide down onto coin directing face 20, from which surface the coins drop upon deflecting surface 49, and progress, after having passed vane 52, into coin refunding chute 43.

Solenoid 34 becomes energized by closing of manually operable switch 62, but that closing of the switch is dependent upon the circuit being kept closed by blades 56 and 58 of multiple contact switch 57, that pair of switch blades being wired in series with switch 62. If the contticts of these blades are separated, no current can pass to solenoid 34. The opening of blades 56 and 58 is effected, for instance, by partly pulling a knob or partly depressing a button, not shown, which would normally cause the delivery of merchandise from the machine when operated to the full intended extent. Thus, when the would-be purchaser tries by such incomplete operation of the knob or button to obtain merchandise, while at the same time closing switch 62 to have the deposited coins refunded, he will be foiled in that attempt since such partly'eifective operation of the knob or button is designed to cause a slight movement of switch-actuating means 68, such movement, no matter how slight, being sulficient to temporarily separate the contacts of blades 56 and 58.

Assuming now the would-be purchaser wishes to obtain delivery of merchandise, he must either fully depress the button or fully pull the knob, whereupon switch actuating means 63 are operated to their full extent, that is to causenot only the separation of the contacts of blades 56 and 58, but also the closing of the contacts of blades56 and 67. At that moment solenoid 35 becomes energized and attracts armature 33, the latter moving lever 27 in counterclockwise direction, thus swinging coin control 18 to the left-hand position as seen in Fig. 6.

As a resultthe coins first retained in the funnel will slide along directing surface 21 of the coin control and drop upon deflecting surface 50, which latter guides the coins into a coin receptacle, not shown, while at the same time the desired merchandise is being delivered to the purchaser.

Assuming =no.w that the device forms a part of an automatic telephone pay station, the operation will be very similar to that described above except that manual switch 62 is not actually operated manually but becomes operated when either the receiver is replaced on the hook or when actuated by the telephone operator. In every other respect, however, the function of the device is very similar to that described in connection with the vending machine.

The electric diagram discloses a specific arrangement of the wiring, including specific switches and means for actuating them, all for the single, purpose to facilitate the understanding of the operation of the, present device and without any intent to in any way limit the scope thereof, since it appears quite evident to any one skilled in the art that the electric control for a device of the type indicated can be solved in a great number of ways, depending upon the manner, purpose, intended use and location of the device.

By the same token, while in the foregoing a specific embodiment of the present invention is disclosed, it is obvious that its structural arrangements may undergo changes both in their form as well as in their relative disposition when the device is to be adapted to different requirements, for which reason it is believed that such changes or possible modifications are deemed to reside within the scope of the present disclosure as defined in the annexed claims.

What is claimed as new is:
