IIIIIIIIII N .ENTORS. cs D.KAUPMAN E A. REEDJR1 osEPH EJJALLY CUHN CHUTE GUARD MEANS The so-called captive-coin fraud, employing a valid or acceptable coin element to which is attached a fine tough wire or synthetic filament or strip by means of which the coin can be jiggled or retracted after passing the testing means to procure repeated fraudulent operations of the master switch or other vending machine control, has numerous variations requiring different preventive means as well as combinations; of preventive arrangements, such as filament-cutting knives, snares, and movable trapping devices variously positioned within and exteriorly of the chute.

The present improvements are particularly related to equipment employing auxiliary fraud-preventive means of the type disclosed in US. Pat. No. 3,279,574 intended to be mounted closely adjacent the exit for acceptable coins in a conventional drop-type coin-testing chute and serving further to defeat the captive coin fraud by receiving the accepted coin and subjecting it to certain supervisory operations, for example, in the case of the patented device mentioned, to hold the accepted coin in a certain location to control supervisory vending circuits to permit a single vending operation only while the coin is disposed at such location.

it has been found that auxiliarycoin-handling devices ofthe type described can be defrauded by a captive coin which is skillfully retracted at the instant it is released by the detecting fingers, in a way to operate the master switch of the vending machine and then be quickly retracted for a repetition of the operation any number of times; but in order that this form of fraud can be practiced a space is required between the coin chute and auxiliary device for the purpose. The presently disclosed guard means automatically blocks off the needed space which would exist at the coin exit as soon as the accepted coin clears such exit, as will be more fully explained in view of the following description and annexed drawing in which:

FlG. l is an elevational view of a coin-testing chute and its mounting cradle, together with an auxiliary supervisory coinhandling attachment;

F116. 2 is a magnified fragment of the coin acceptance exit region of the coin-testing chute of FIG. 1;

HQ. 3 is a magnified fragmentary detail of the novel fraudpreventive dog means as seen looking down upon lines 3--3 of HG. t;

FlG. t is a magnified fragmentary detail of the fraudpreventive means as seen from the right side along lines 4-t of FIG. l;

lFlGS. h and EA are magnified fragmentary views showing the dog in respectively normal and pivotally operated conditions looking in the direction of lines 5-5 of FIG. ll;

FIG. it is an enlarged exploded detail of the fraud-preventive dog structure;

FIG. all is a perspective detail of thedog with added counter balance;

HG. 7 is a perspective view, to reduced scale, of the reject chute;

The illustrative coin chute apparatus shown in FIG. l is conventional in that it comprises a known type of mounting cradle lltl which will be supported in association withsome coin-controlled apparatus (not shown) such as a vending or amusement machine, such cradle serving to retain any of several known types of coin-testing chute ll removably seated therein, as by means of pivot pins on the chute and springurged catches l2 forming part of the cradle and latching onto said pins on the sides of the coin chute. Such a cradling arrangement facilitates installation and removal of the coin chutes for servicing and replacement, as when changing coin denominations, and so on.

The mounting cradle in the illustrative installation further may include various auxiliary control and coin-handling appendages, such as a master coin switch mounted on a plate to which is preferably attached to, or perhaps a part of, the cradle. The coin switch has an actuating finger 17 with an offset end disposed in an arcuate slot 18 in the plate, and aligned slot means formed by further plate means 19 defining a channel 20 in which the accepted coin, after leaving the testing chute exit M, will be confined for operation to depress the switch finger to the dotted-line position and operate the switch before finally gravitating free of the auxiliary control unit when released by certain coin-holding finger means therein (not shown), partly seen at 23A, 23E.

Also supported at the side of the cradle is another switch means 22 usually forming part of such an auxiliary coin-handling attachment as disclosed in the aforesaid US. Pat. No. 3,279,574, and which is controlled by an extension 23 from the aforesaid coin-holding finger means situated interiorly of the mounting cradle for cooperation with certain portions of the testing chute passage in ways not material to the operation of the disclosed improvement and therefore not requiring detailed description here, it being sufficient for present purposes to observe that in the construction shown in MG. 1!, unacceptable coin elements C-ll which are rejected by the testing chute will exit therefrom at a point from within the larger irregularly shaped barnacle plate has leading to reject exit 27 (FIG. 7 also), while coins (7-2 which are accepted will exit from the bottom of the testing chute at a point behind the small wall portion 26 just above the switch-operating finger 117, enlarged fragmentary portions of both of these chute passages being seen in M03. 3 through 5A.

Thus, in FIG. ll, an accepted coin is intended to depart at M from the coin acceptance exit of the testing chute and gravitate directly into the auxiliary guide chute portion llill normally to emerge finally therefrom as indicated by the dotted-line representation of the coin 02 for the purpose of transiently depressing the switch-operating arm 117 to the dotted-line position, and actuating whatever vending or other apparatus may be controlled by the coin chute means.

In order to prevent fraudulent retraction of the accepted s coin back above the auxiliary chute section 119 from which it would normally depart, the main chute exit is blocked by a special pivoted guard member or dog 3h, lFlGS. l and 2, having a downwardly curved camming edge 31!, PEG. 4, projecting into and laterally across the coin exit chute section in position to be engaged by the exiting coin 02;, t lt 5, and be pivoted out of the path thereof, lFlG. 5A, in coin-handling means.

The dog or gate structure is such that it may be applied to existing coin-testing chutes at the location of the coin acceptance or exit passage M as by the construction depicted in FIG. 6, comprising a small mounting plate 33 shaped to fit beneath the coin rejection chute structure Ed, said plate 33 having an offset tab 1% pierced to provide a pivot hole 3% and notched to provide a dog stop 31b to limit the downward or coin-passing swing of the dog or gate.

The coin-blocking dog Ml, itself, Fit]. 6, comprises a stamping including a central portion 30A pierced as at 3th to pass a pivot 39 staked into the hole 35, the stamping having, in addition to the nose portion or camming edge 311, an offset flange portion 40 pierced as at dll to receive any necessary counterbalancing weight which may be required in the event coins of heavy denomination are to be handled, such additional weight being afforded by a rivet counterbalance member all) or the like, FIG. 6A, of suitable mass when required.

Along a bottom edge of the dog stamping, a small tab M is struck out to serve as a limiting stop for the upward movement of the dog, this tab being intended to abut a lower edge portion 33E of the Mounting Bracket, as at db, PEG. 3.

In order to position the exit-guarding dog means on the testing chute itself and permit ready installation and removal of the latter relative to the cradle and without interference with such auxiliary attachments as may be present, such for example as that in the aforesaid US. Pat. No. 3,279,574, an openended clearance slot all is utilized in both front and back wall portions of the testing chute, and the dog is dimensioned, and its pivot point is located on the small attaching plate 33 in a manner to dispose the lower margins of the dog substantially flush with the lower margins of the coin-testing chute, as indicated generally at 50 in FIGS. d and 5, by reason of which it will be seen that any dmired auxiliary coin-handling apparatus passing into the auxiliary may be positioned very close to, and in alignment with, the coin acceptance exit of the chute at 14.

The exit-guarding gate structure is preferably made as an attachment which can be added to or omitted from existing commercial coin-accepting and testing chutes, and to this end the peculiarly shaped reject chute section 24 is a bamacle structure normally attached to the testing chute by screws 28A; and thecoin-blocking dog plate 33 is shaped to fit with an angular portion at 24A of the reject chute and to be fixed in operative assembly by only one screw 28A (FIG. 2) which attaches the reject chute. Thus, the unidirectional, exit-blocking dog or gate means 30-33 constitutes an attachment which may easily be assembled with or omitted from testing chutes such as described, depending upon whether as a part of the mounting cradle as shown, or in other disjoined arrangements known in the art and requiring very close proximity to an exit such as that at 14.

We claim:

1. in combination with a gravity-type coin chute having a coin exit at a lower marginthereof and an auxiliary coin-handling device receiving coins from said exit and having a control member situated in predetermined spatial proximity beneath said exit to be engaged by an exiting coin for only a single transient operative engagement with said member, antifraud means comprising a coin-passing gate structure situated in close adjacency to the margins of said exit and operative to open to permit a coin element to depart from, but not to reenter, said exit when closed after passage of a coin, and defining a coin-immobilizing zone between said gate in closed condition and said control member effective to confine and substantially immobilize a captive type coin in said zone against fraudulent retrograde manipulation sufficient to effect more than one actuation of said control member.

2. The combination of claim 1 wherein said gate structure is an auxiliary device adapted for attachment to said coin chute and includes a bracket, and means for attaching the same to said chute, and a gate member pivoted on said bracket and entering said chute through a slot therein closely adjacent the margins of said exit, with a coin-engaged portion lying in the path of, and moved out of the way of a coin negotiating said exit, together with means operative to yieldingly maintain said gate member in normal coin blocking position and permit the same to be opened for exit of the coin and to restore the same quickly to said blocking position after passage of said exiting coin.

3. Apparatus according to claim 1 wherein said gate member has a leading edge lying across the path of a coin approaching said exit and said edge is sloped to provide a camming surface facilitating the opening of the gate responsive to engagement of an exiting coin with said leading edge.

4. Apparatus according to claim I further characterized in that said gate member is provided with an integral stop fonnation engageable with a part of said bracket to define the closed position of the gate member.

5. Apparatus according to claim 1 further characterized in that said gate member has an offset portion perforated to receive a counterweight element the mass of which may be selected to effect the return movement of the gate member to closed condition and permit it to yield and open responsive to engagement by an exiting coin of predetermined mass.
