safety member 78 when the front door 4 is closed and the keeper 77 is in the locked position. The linkage 79 is connected to the keeper 77 and is operative to move the safety member 78 within the plunger guide member 66. When the keeper 77 is moved to an unlocked position, the projections 80 are positioned in an aligned relation with each of the cam portions 59 of the respective plungers 53 thereby preventing dispensing of medicine when the front door 4 is open or the keeper 77 is in an unlocked position. i I

A suitable selector knob 81 is mounted on the cabinet front 5 and suitably positioned for a person to operate same to select a desired medicine'in one of the plurality of magazines 7. The selector knob 81 is operatively connected to a carriage 82 having a rod 83 resiliently mounted therein and positioned to engage a selected stem portion 58 of a respective plunger 53 for moving the respective magazine 7 to its medicine dispensing position 20. g 7

In the illustrated structure, the selector knob 81 positions a wheel 84 having a plurality of circumferentially spaced recesses 85 to receive and retain a suitable ball resiliently 'supported by a suitable leaf spring86; Each of the recesses 85 is associated with a selected position of the carriage 82 for moving a selected magazine 7 to its medicine dispensing position 20. The number of recesses 85 in the wheel 84 corresponds with the number of magazines 7 however. an additional series of magazines 7 may be mounted in the cabinet 2 and selected by additional rotation of the wheel 84 with each of the recesses 85 associated with one of the magazines 7 in each series of the magazines.

A circular wheel or disc 87 is mounted on a shaft 88 which also supports the selector knob '81 and the wheel 84 A suitable flexible connecting member, such as a cable 89, is wound around the periphery of the wheel or 'disc'87 and is connected to the carriage 82. Thevnumber of turns of the cable 89 around the disc 87 corresponds to the number of series of magazines 7. Suitable idler pulleys 90 are positioned within the cabinet 2 to guide the carriage 82 in its travel to the respective selected positions. i

In the illustrated structure the carriage 82 is movable along a track 91 formed by opposed rail members 92 each having suitable grooves or recesses 93 therein for receiving corresponding parts of the carriage 82. I

An elongate bar 94 is positioned to engage the rod 83 and to move same thereby moving the selected magazine 7 to its medicine dispensing position 20. In the illustrated structure,

The lock 96 with the keeper 95 is now in a position to be moved along a way 100 in the cabinet front 5 and thereby move the elongate bar 94 by means of the linkage 97. Each time the lock is moved along the way 100 a single unit of medicine is dispensed from the selected magazine 7.

Each of the keys 98 has a plurality :of projections 101 along one edge for unlocking the lock 96 and permitting the lever or keeper 95 to also be turned through the same 90 ngle. The opposite edge of the keys 98 also has one or more projections 101' positioned therealong to serve 'as a representative code designation of the person having the respective key 98.

The keys 98 with the respective representative code designation are operative to activate a suitable recorder 102 during movement of the lock 96 along the way 100 and record the code designation of the person operating the medicine dispensing apparatus 1. The recorder 102 is operatively connected to the selector knob 81 thereby also recording the particular type of medicine dispensed. A suitable time clock 103 is also operatively connected to the recorder I02 thereby recording the precise time of the dispensing of the selected medicine. 1

A side door 104 provides access to the recorder 102. It is preferred that only selected key personnel, such as a head floor nurse in a hospital or a chief pharmacist or the like, having access to the recorded information especially when the medicine dispensing apparatus 1 contains sensitive medicine, such as narcotics. The. recorder 102 is also particularly' adapted for inventory control information in that quantity of each type of medicine is recorded and may be used to reorder new magazines 7 containing the medicine supply exhausted.

A plurality of suitable indicators, such as light bulbs 105, are positioned to indicate the respective magazines 7 with which the rod 83 is aligned. In the illustrated structure, the bulbs 105 are mounted on the cabinet front 5 where a suitable switch such as an enclosed normally open switch 106 having one lead connected to the respective bulb 105 and the other leadconnected to a suitable power source (not shown), such as a battery contained within the medicine dispensing apparatus l or a suitable electrical outlet. A suitable magnet 107 is mounted on the carriage 82 adjacent the line of switches 106 and is operative to close the normally open switch immediately adjacent the carriage 82 thereby completing the circuit to the respective bulb 105.

It is also preferable that a suitable table 108 be mounted on the cabinet 2, as for example on the front door 4 with the table 108 listing the contents of each of the magazines 7 thereby assisting a person in selecting the desired type of medicine.

In operation a person, such as a nurse, desiring a single unit of a certain type of medicine moves the selector knob 81 to align the rod 83 with the respective stem portion 58 of the from' .-.the abutment member 99; and moves the key 98 downwardly in the way 100 thereby dispensing a single unit of medicine from the selected magazine 7. The unit of medicine is ejected or discharged into the hopper 3 and moves by gravity into a chute 109 and comes to rest on a normally closed trap door 110. The person making the selection then takes a suitable receptacle or container, such as a paper-or plastic cup (not shown), and places the receptacle or container against a lever 1 11 and moves same rearwardly overcoming the force of a suitable resilient member, such as tension spring 112, and removing the support for the trap door [10 thereby permitting the door 110 to open. In the illustrated'structure, the lever l l land the trap door 110 are pivotably mounted about pin 113; the selected unit of medicine thereby falling into the container from which apatient may take the medicine.

All of the medicine in the medicine dispensing apparatus 1 is protected from human contact or other contamination from the time the medicine is enclosed in the respective magazines 7 until dispensed through the chute 109 and trap door 110 into the container thereby removing a possible source of contamination to recipients of the dispensed medicine.
