Abstract
Abstract A coin control system for determining whether proper coinage has been inserted to start a coin operated device. The coin in vertical orientation falls onto an inclined ramp, down which it rolls past a mechanism which detects magnetic materials. The coin rolls past a photocell which projects a beam positioned to be interrupted by only the upper limb or arc of the rolling coin. The ramp is mounted between closely spaced side plates and may be vertically adjusted between them with respect to the photocell so that it can be set for coins of different sizes. The coin control mechanism and a coin collection box are each separately lockable within a housing and are both further protected by a specially removable, lockable cover.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
277 words
A coin control system for use with a coin operated device, said system comprising, a pair of vertical, laterally spaced apart side plates, ramp means between said side plates and presenting a downwardly slanting ramp along which a coin can roll downwardly, a coin insertion opening above an upper end of said ramp, a magnet in one of said side plates, adjacent the path of coin movement down said ramp, a magnetic switch proximate to said magnet, said switch being responsive to a change in the magnetic field of said magnet when a slug passes said switch while moving downwardly on said ramp, photocell means projecting a narrow light beam across said ramp in a position to be interrupted only by the top of a coin of predetermined diameter on said ramp, means for receiving coins coming off a lower end of said ramp, each coin inserted through said opening falling onto said ramp and rolling continuously downwardly on said ramp past said magnet and photocell means and dropping into said receiving means, and circuit means responsive to a change of position of said magnetic switch when a magnetic slug passes it on said ramps, so as not to start operation of said coin-operated device, said circuit means further responsive to an interruption of said beam to initiate operation of said device unless said switch has changed position in response to a slug, said ramp means being vertically adjustable, with respect to said light beam, between said side plates, so that the ramp can be set a desired distance below said beam such that said beam is broken only by coins larger than a certain minimum diameter.
Claim 2
Dependent Claim
277 words
A coin control system for use with a coin operated device, said system comprising, a pair of vertical, laterally spaced apart side plates, ramp means between said side plates and presenting a downwardly slanting ramp along which a coin can roll downwardly, a coin insertion opening above an upper end of said ramp, a magnet in one of said side plates, adjacent the path of coin movement down said ramp, a magnetic switch proximate to said magnet, said switch being responsive to a change in the magnetic field of said magnet when a slug passes said switch while moving downwardly on said ramp, photocell means projecting a narrow light beam across said ramp in a position to be interrupted only by the top of a coin of predetermined diameter on said ramp, means for receiving coins coming off a lower end of said ramp, each coin inserted through said opening falling onto said ramp and rolling continuously downwardly on said ramp past said magnet and photocell means and dropping into said receiving means, and circuit means responsive to a change of position of said magnetic switch when a magnetic slug passes it on said ramps, so as not to start operation of said coin-operated device, said circuit means further responsive to an interruption of said beam to initiate operation of said device unless said switch has changed position in response to a slug, said ramp means being vertically adjustable, with respect to said light beam, between said side plates, so that the ramp can be set a desired distance below said beam such that said beam is broken only by coins larger than a certain minimum diameter.
Claim 3
Dependent Claim
30 words
The coin control system of claim 1 wherein said ramp means is vertically movable between said side plates, and including means for securing said ramp means in a desired position.
Claim 4
Dependent Claim
50 words
The coin control system of claim 1 wherein said magnet and magnetic switch are mounted on opposite sides of said ramp, up the ramp from the light beam, and wherein the switch is connected to prevent operation of said device if the switch detects the passage of a magnetic slug.
Claim 5
Dependent Claim
94 words
The coin control system of claim 1 wherein the photocell means comprises a light source and a light receiver, both mounted from the same one of said side plates, said photocell means including a mount presenting one of said source and said receiver, said mount extending across the ramp to the other side plate and there returning toward the other of said mount and receiver, the mount being spaced above the ramp sufficiently that coins of predetermined size can pass beneath the mount but will interrupt a beam from said source to said receiver.
Claim 6
Dependent Claim
20 words
The coin control system of claim 1, further including operating circuitry which is mounted on one of said side plates.
Claim 7
Dependent Claim
33 words
The coin control system of claim 5, further wherein a noise generator is mounted on one of said side plates and is energized when a predetermined type of coin passes off said ramp.
Claim 8
Dependent Claim
32 words
The coin control system of claim 1, wherein said insertion opening is a vertical slot, the effective height of which is determined by a height adjustment screw which partially closes said slot.
Claim 9
Dependent Claim
67 words
The coin control system of claim 1, wherein said ramp means includes a T-shaped member between said side plates, said member having an angulated top surface which presents said ramp, said member having a vertical leg which is guided for vertical sliding movement between said side plates, and means engageable with said leg to secure the same in a given position with respect to said side plates.
Claim 10
Dependent Claim
43 words
The coin control system of claim 1, further including an anti-retraction dog swingably mounted above said ramp, said dog being rotatably to permit the passage of a coin down said ramp past it but blocking reverse movement of a coin up the ramp.
Claim 11
Dependent Claim
67 words
The coin control system of claim 1 mounted with a coin box below a lower end of said ramp, said coin box having an opening through which a coin falls into it from the lower end of the ramp, further wherein both said coin control mechanism and said coin box are removably mounted in a common housing, and each of them is separately lockable to said housing.
Claim 12
Dependent Claim
45 words
The coin control systems of claim 10, further including a removable cover for said housing which must be removed in order to gain access to unlock and remove each of the coin control mechanism and the coin box, said cover being lockable to said housing.
