ATTORNEY Patented Feb. 24, 1931 UNITED STATES PATENT OFFICE CHARLES WEBER, OF, NEWARK, NEW JERSEY, ASSLlGNOR T0 AMERICAN COIN SELECTOR CORPORATION, OF NEW YORK, N YQA GORIBORATION OF NEW YORK com cnu'rn Application filed February 11,1930. Serial No. 427,535.
This invention'relates to coin controlled vending machines and more particularly to a device for detecting coin substitutes when fraudulently used in such machines.
. Numerous expedients have been used to detect the presence of iron slugs and other metallic coin substitutesybut it has been found thatnon-metallic substances such as cardboard may be effectively used as substitutes for coins in certain types of vending machines.
In such types of machines the coin usually serves as a clutch and the weight of the coin is immaterial. Consequently, any stiff material such as cardboard may be used to produce the clutching action in such machines.
It is an object oi this invention to provide a device for preventing, 1n vendmg machines,
weight than the required coin. i Afurther ob ectis the provision of means for detectlng in vending machines thepresthe use oi a coin substitute which is lighter in once of 'coin'substitutes containing magnetic metals. I
A further object is the provision, in vending machines, of a device for ejectingimproper coin substitutes so that they will not interfere with the subsequent operation of the machine when the proper coin is employed.
These and other advantages, which will laterappear, are accomplished by the simple and practical construction and arrangement of parts hereinafter described and exh1h1ted a portion of a channelled guide used in thedevice.
Referring to Figure 1, a vending machine having a casing 6 is shown to have mounted therein a chute 7 adapted to receive coins an arcuate path and is directed onto a circular channelled track 9 lying in a vertical plane, and thence passes into the widened mouth 11 of the lower chute 10.
The proper coin, when inserted in aperture 8, acquires, while passing through chute 7, momentum suliicient to carry it around the track 9 so that it may fall into chute 10.
Now, the track 9 hasside walls of a height considerably less than thc radius of the coin, and when a coin substitute of lighter weight than the required coin is used in the machine, such substitute will be ejected as it partially traverses the track 9; for its weight and travel through chute 7 will be insufiicient to give it the momentum necessary to carry it entirely around the track 9 andinto the mouth 11.
Such light weight coin substitutes travel; about one-half the distance around the traclc andthen fall laterally into the lower part of j one wall of the track cut away as shown in Figure 3. a e y i i The action of the magnet will be to draw the coin upwardly against the upper laterally PlOJGClllllg lip 14 or the lower laterally pro- 3ect1ng lip 15, which lips deflect the coin sufiiciently to cause it to fall. downwardly into "he lower part of easing (5.
From the above description it will be seen that I have provided a simple device for detecting the presence of fraudulent coin sul stitutes in vending apparatus, which device i also is eitective for ejecting such coin substitutes so that they will not interfere with the subsequent operation of the machine.
The foregoing disclosure is to be regarded as descriptive and illustrative only, and not as restrictive or limitativeot the invention, of: which obviously an embodiment may be constructed includmg many modifications without departing from the'general scope herein indicated and denoted in the appended claims. Having thus described my inventiomwhat I claim as new and desire to secure by Letters Patent, is: i
' 1. In, avending machine, a coin chute having a looped portion intermediate its ends,
said looped portion comprising a relatively I shallow channel so that coins having less than a;.predetermined weight may fall out of the channel. 1 i
2. In a vending machine, a coin chute, comprising an upper tube and a lower tube, said tubes being arcuate, and rectangular in 5 cross section, and a circular shallow channel connecting the tubes, so that coinshaving insufiicient momentum "will fall out of the channel. V V 3. In av ending machine, a coin chute comprising an upper tube and. a lower tube,'a
shallow channel connecting the tubes, said channel being looped to form a substantially circular path fora coin so that coins having insufficient momentum will fall out of the channel. I p
I l. Ina vending machine, a coin chute, comprising an upper arcuate tube and a lower tube, anda channel connecting the tubes, the
. lower tube having a widened'mouth comk municating with the channel, said channel being looped to form an arcuate pathso that coins having insufficient momentum will fall out of the channel before reaching the mouth p ofthe lower tube.
'5. Ina vending machine, a coin chute comprising an upper arcuate tube and a low er tube, a channel connecting the tubes, said channel being looped toprovide an arcuate path, amagnet positioned adjacent thefjunc' 40 tion'oi the channel and the uppertube to attract coins containing magnetic metals, and lips on the tubes .to deflect coins attracted by the magnet, said channelv having a portion of its outer wall cutaway so that coinsatt racted by the magnet may fall out of t 1e channel,
