0F SEATTLE, VIASHINGTON, A CORPORATION or WASHINGTON COIN CONTROLLED- MECHANISM Application filed January 3, 1930. Serial No. 418,334.

This invention relates to improvements in coin controlled mechanism.

It is a feature of the invention. to provide a coin chute having an entrance throat which is proportioned to admit coin or other token ofnot more than a prescribed diameter and which does not exceed a given thickness, the throat being shaped in a manner to prevent entrance of a coin or token that is buckled or bent. 7 A further feature of the invention consists in means for arresting coins or tokens in their passage through the chute in such a manner that a plurality of such entities can be inserted, one in superimposedrelation to the other or others, and whereby the entities will be separately and successively acted upon to cause a series of vending operations for each genuine coin, the spurious entities being acted upon to prevent a vending operation as a resultof the presence thereof, and irrespective of the fact that a token or genuine coin may be of a less than the prescribed diameter.

An object of the invention is to provide means for detecting the spurious from the genuine of the entities-by gauging the thickness thereof, the slugs to a great extent, being provided with centrally disposed openings in each, thereby causing a registration of no thickness, while av dime or prescribed coin that is worn too thin, will also be incapable of causing a vending operation.

It is a feature of the invention to provide means acted upon by, and subsequent to the detection operation, for causing genuine coins of the usual thickness to be deflected into or toward a coin box, and coins that are too thin and also spurious entities, to be deflected in a manner to be returned to the purchaser.

One of the novel features of the invention resides in detection means operatively connected with mechanism for arresting vending operation, in interdependent relation.

A further feature resides in means for discharging steel or other spurious entities before the latter reach the detecting means.

The invention has many other features and objects which will be more fully described in connection with the accompanying drawings and which Wlll be more particularly shown in Fig. 10.

Like characters of reference designate similar parts throughout the different figures of the drawings.

The device of this invention is adapted for use in connection with the vending of any type of merchandise or articles and therefore it has not been shown associated with any special type. I have however, generally indicated at 1, the top of the case or casing in which the mechanism is enclosed and, in this embodiment, the place where a coin, token or like entity will be inserted.

Throughout the claims and the specification, I will use the words entity or entities generically to coins, slugs and tokens, thereby avoiding alternativeness, repetition, and antecedent confusion.

,, An entrance or throat device is mounted 'inthe top 1, and consists of a plate 2 having a slot 3 of a length to permit insertion of a coin of prescribed or maximum diameter and no larger. The width of the slot 3, is proportioned to limit the insertion of an entity greater than a predetermined thickness, which, in the present instance, is a five centpiece or nickle. Depending from the plate 2, are lips 4 which are so closely spaced that if an entity is bent or buckled, such entity can only be partly inserted, as will be seen by reference to Fig. 12. These lips terminate at 5, in very close endwise relation to the ma n vcoin chute, and in practice, these lips arenot connected near or at the end portions thereof, the latter being open. It

will beunderstood that these lips 4 will also 35 prevent insertion of an entity of less than the prescribed diameter, if the latter is buckled or bent, and such entity may also be of a reduced diameter with respect to the prescribed diameter for which the device is designed and proportioned to work. Reference will next be made to the coin chute and the various features of structure with which the latter is equipped.

The entrance to the coin chute is indicated at 6, closely disposed to the terminals 5, of the lips 4, asshown in Figs. 1 and 12, so that the lips 4 will guide the inserted entity into the coin chute before such entity has passed through or from between the lips 4, as will now be clear. This coin chute has what will be termed an entrance section 7, which is vertically disposed for gravity descent'of an entity rherethrough or therein. Said coin chute has an initial or slug discharge section 8 which isshown disposed in offset relation to the entrance section 7, slanting'down-wardlyand laterally as shown in .se'ctiorr'9, having a final discharge end 10.

Extending laterally and diagonally down- .wardly from the discharge section 8, is a slug section 11, having a discharge outlet 12.

,As will be seen more particularly in Figs. 13

and 14, the slug section 11, junctures with the section 8 in a manner to form a release passage 13 for what I will term magnetic entities, such for instance as steel slugs. A magnet 14, preferably although not necessarily of a permanent type, is secured to a mounting 15, suitably anchored to the coin chute. The poles 16, of said magnet extend across the bottom of section 8, and as a steel or like slug rolls down the chute, it is attracted by the magnet and thereby diverted into the slug section 11, as will now be clear. Means such as a thin non-ferrous strip 17, may be disposed as shown to prevent an attracted entity from freezing to the poles of the magnet 14, thereby insuring its discharge downwardlyin chute 11. Said strip 17 may be anchored'at 18.

Thus it will be seen that I have provided means acting intangibly or magnetically for discharging that type of entity subject to This base 19 is adapted to be secured in the structure in which the vending and coin controlled mechanism are disposed. At the discharge end 10, of the coin chute, the base is cut-away or bifurcated to form substantially forked sections 20 and 21, to be later described.

In further description of the operative section 9, of the coin chute, reference will next be made to a feature whereby all entities, whether genuine coins of prescribed diameter or less and all slugs except those magnetically deflected, will be arrested, or temporarily arrested in the coin chute section 9, for purposes of detection of their character.

In the description of this feature, reference will be made to Figs. 4, 5, 7 and 8. An entity arresting means is provided which, in the present construction takes the form of a member or plate 22. This is a rocking plate and preferably a floatingly mounted plate,'and means which will later be described, is provided for imparting rocking movement to said plate. v

Said plate 22, has a set of studs 23 spaced for arresting entities of normal or prescribed Ill;

and across the chute passage, as shown in Fig. 4. Y I

Said plate 22, is also provided with a set of arresting studs 25, which in this construction, is the upper set of studs and which are sulficiently closely spaced not only to arrest an entity of prescribed diameter but one of less than such diameter, such for instance as a dime. The outer chute wall 9 is provided with openings 26 for projection of studs into the coin chute as shown in Fig. 5. By reason of the fact that the plate 22 is floatingly mounted, I preferably taper the studs 23 and 25, and

' the openings 24 and 26 are somewhat e11- larged to alford ample'clearance. It will be seen from Fig. 8, that the upper studs 25, are capable of supporting a plurality of superimposed entities irrespective of whether they are of the prescribed diameter, the importance of which will be later described.

Reference will next be made to the means for floatingly mounting the plate 22.

At its upper corners, the plate 22 is cut away as shown at 27 and guiding pins 28, mounted on wall 9 of the coin chute, extend outwardly through such cut away portions 27, and serve as a guiding means for rocking movement of the upper portion of plate 22.

The lower corners are shown cut away or interrupted at 29 and a bail 30 extends across the lower margin of said plate and the ends of said bail, as indicated at 31, in Fig, 8, extend inwardly and form guiding studs or pins for coaction with the cutaway portions 29. The guiding pins 31 are anchored to the wall 9 of the coin chute. As the lower portion of plate 22 is not the actuated portion, it'is advantageous to employ a bail so that the bightof the latter will prevent the lower portion of the plate 22from moving outwardly too far.

Means such for instance as springs 32, an'- chored at 33, to the coin chute and "having their free ends 34 bearing against the plate 22, normally serve to urge theplate toward the coin chute, and the thrust exercised by said springs is near the horizontal center of the plate 22.

Reference will next be made to the means employed for imparting rocking movement 'to plate 22.

WVhat I will term a master cam, to be later described in full, is indicated at 35, and is rigidly mounted on a cam shaft 36, which latter is a main operating shaft. This shaft 7 is rotary, carries an actuating and releasing cam stud 39. An actuating lever 40, is pivoted at 41, to the base 19, in the rear of cam 35, and is provided with an actuating are 42 struck from a center radius greatly reslidably engages the slot 48, of an actuating or rocking arm 49, that is rigidly secured to the upper portion of plate 22, as will be clearly seen by reference to Figs. 1 and 4.

Reference will next be made to a novel means for detecting the character of entity that is arrested by plate 22.

A lever 50, which I will term a detecting lever, is hinged to the base 19 at 51, to swing in a substantially horizontal plane about a substantially vertical axis. A spring 52, normally urges said lever 50, toward the coin chute. Extending transversely through said lever 50, is a coin detecting stud 53, more clearly shown in Fig. 9. Thus stud 53, may be advantageously in threaded engagement with said lever 50, and a lock nut 54, provides means for securing the stud 53 in adjusted positions. The plate 22, is provided with an opening55, through which said stud 53 freely extends, and an opening 56, in the wall 9 of the coin chute, permits the stud 53 to extend into the latter, and into engagement with an en ity that has been arrested by studs 23, of plate 22, for purposes of detection.

The free end 57 of said lever 50, is provided with a slotted or lost motion connection with one arm 58, of a bell crank lever, the remaining arm 59 of which, is pivoted at 60, to a boss 61, projecting from base 19. Arm 58, is shown provided with a slot 62, and a pin 63, mounted on lever 50, completes the slotted connection before referred to.

Reference will next be made to instrumentalities operatively interposed between the master cam and lever 50, whereby an interdependent relation is established be tween said cam and said lever.

- What I will term a break-joint pawl, is shown in two parts and the pivoted or supporting part consists of a pawl. arm 64 which is pivoted at 65, to boss 61. A pawl part or portion is designated at 66 and is shown to be of U-shape, in cross section. Said pawl portion 66, is united with the supporting portion 64, by a pivot 67, and the lower end 68 overhangs the pivotal connection so that a break oint movement of the parts toward a straight or linear position, is limited to the relationship shownin Fig. 1. 69 of pawl section 66 partly laps the side faces of the cam 35 and rides on the periphery thereof, as clearly shown. I preferably make the part 64 in theform of a bell crank, anarm 70, thereof, forming a suitable lever- The cam end age'for connection of one end of a spring 71,

the free end of which extends slidably through a lug 72, on pawl 66. This spring I is arranged and tensioned to urge the parts 5 66 and 6& toward and into the position shown in Fig. 1, but permits the parts to buckle or break jointas shown in Fig. 2, for a purpose to be more fully described later on. In actual practice,'a spring is not absolutely necessary in order to maintain the pawl parts 66 and 64 in engagement with the cam 35 although a spring tension makes the pawl action more responsive. Therefore, I have shown a tension spring 73, having its lower end connected to arm 70 to urge the pawl end 69 into engagement with cam 35.

The pawl member 64, is provided with an opening 74:, into which projects a lug 75, forming a. part of arm 59, thereby forming an operative connection between the breakjoint pawl and the detecting arm 50. Thus it will be clear from Fig. 9, that as the breakjoint pawl is shifted to the right of its pivot 65, the bell crank arm 58 will be shifted out wardly from base 19, thereby moving arm 50 in the same direction'and withdrawing stud 53 slightly from the coin chute, and that a movement of the break-j oint pawl to the left of Fig. 1, or as viewed therein, the lever 50 would be allowed to move toward the base 19 and cause a corresponding entrance of stud 53 into the coin chute. The operation of this portion of the invention will be more fully described later on.

In order to make the construction clear, I have just described the separate parts 64 and 66 of the break-joint pawl but hereafter, I will refer to this feature as the break-joint pawl and will provide it with a generic designation A.

Before enterlng into a description of the master cam 35, I will first describe a check pawl, the function of which is to check the cam 35 against retraction from an operatively advancing position or movement.

Said check pawl is indicated as a whole at 76 and is pivoted at 77 on a boss 78, which projects from base 19. Said pawl has a pawl arm 79 which is provided with a ratchet pawl foot 80 which is flat or straight and which is adapted either toengage an arresting notch in the cam 35, to .be later described, or en gage ratchet tooth portions of said cam. Said pawl has an arm 81, that is adapted to be spring actuated, and for convenience, I employ spring 73, to which said arm 81 is connected. This spring 7 3 maintains said foot 80, in engagement with cam 35.

Said check pawl 76 performs additional functions which will next be described in detail.

An arm 82 of said pawl is connected with an operating rod 83 which extends downwardly between the cam 35 and base 19 and is connected at its lower end 84, to an arm 85,.as more clearly shown in Figs. 4 and 5. This arm 85 is mounted on a coin diverter shaft 86, journalled in bearings 87 and 88, formed on forked sections 21 and 20, respectively, of base 19. Mounted on said shaft 86, is an improved coin or entity diverter which, as shown, consists of a U-shaped sheet of material having a bight 89 and limbs 90, and said limbs 90 may be secured to said shaft by means indicated at 91. Thus it will be seen that the top of this diverter is spaced some distance below the discharge end 10, of the coin chute and the lower edges of the limbs extend slightly below the shaft 86, to which they are mounted. V

The function of this diverter is to divert genuine coins rearwardly into a coin box, generally indicated at 92, and to divert slugs or unvendable coins forwardly into asuitable return receptacle, which is generally 'indicated at 93, and which is accessible to the purchaser while of course the coin box 92 is inaccessible except to the service man for the machine. 7 V

A counter 94, is mounted on section 21,-and is provided with an actuating arm 95, the

latter being pivoted at 96, to a link 97, the

remaining end of which is jointly connected with arm 85, to the lower endSt, of operating rod 83. Thus, the operating rod 83 functions to actuate the diverter and the counter, in a manner to be more fully described in the subsequent description of theoperation.

I will next describe the structure and pur pose of the master cam.

Although a circular and rotary form of cam is not essential to my invention, this form is herein shown mounted on cam shaft 36. Said cam 35 is provided with what I will term an arresting notch which is indicated at 98, and which is a somewhat elongated and rectangular type of notch having a terminal or arresting end 99, adapted to coact with the break-joint arresting pawl, and a terminal or arresting end 100, which is adapted to coactwith the foot 80,- of the check pawl 79. This arresting notch is disposed radially inwardly from the balance of the cams periphery, as will .be clearly seen, and the purpose of which will be later developed. The major peripheral portion of the cam 35, as indicated at '101, has the greatest diameter and is provided with ratchet teeth adapted to coact with pawl 79, to prevent any retractive movement of cam 35 i from the rotative movement necessary to complete a vending operation. The vending movement of cam 35, is in a clockwise direction, viewing Fig. 1. r

The terminal 102, of the ratchet portion 101, constitutes an operating hill of the cam from which descends a declining vale 103, also of operating significance, and which terminates at the arresting end100, of notch 98. From the opposite end 99, of said notch extends a concentric hill 104 which merges into an inclining vale 105, the latter terminating at the remaining operating hill 106, which is the opposite terminal of the ratchet portion ofthe cam 35.

Reference will next be made to an improved brake mechanism which retards advance of the cam during a vending ope ation of the latter and which is designed and constructed greatly to relieve the break-joint pawl of strain in arresting the master cam from a vending operation.

Referring to Figs. 10 and 11., a hub 10!, is rigidly mounted or keyed to shaft 36 and is provided with a braking arm 108 which may be formed integral with said hub 10'? and a gear wheel 109, which latter is in one piece with said hub. A braking lever 110, is pivoted at 111, to said base 19 and is provided with a minor braking surface 112 and a'major braking surface 113, with which said braking arm coacts. A 'spring114 has one end anchored at- 115, to base 19, andthe remaining end connected at 116, to the free end of said lever 110. When the parts are in the normal starting position shown in Fig. 1, the braking arm 108 is in the position shown in Fig. 10, which is an abutting relation to the arm 110, thereby affording one of the greatest moments of resistance to vending advance of shaft 36, even though the spring 114 is not under much tension. However, the resistance increases as the end of arm 108 rides on arm 110, as shown in dotted lines, and the operation of which will be more fully described later on. In addition to acting as a yielding brake, this device causes the vending mechanism automatically to return to a starting or normal position after a spurious entity has been rejected.

Before entering into a detailed description of the operation, it may now be informative to state specifically certain functions that the device is adapted to perform so that the latter will be clarified in the light of the preceding description.

The throat device, shown in Fig. 12, will prevent entrance of entities that are mutilated by being buckled or bent, and it will prevent entrance of entities that are either too thick or of a too great diameter.

The magnet will cause discharge of what I term magnetic entities such for instance as slugs made of iron or steel, before such entities reach the detector.

The arresting plate and detector will .per mit coins or slugs of a small diameter to im mediately pass through and be returned to the purchaser, without effecting any vending or other operation of the mechanism. Genuine coins of prescribed diameter that are worn too thin, will also be rejected, likewise slugs of the same character, and slugs that have a central perforation will also be rejected' i I The operation will now be described in detail.

Although not essential to the invention, the machine shown is designed for operation with nickles. However, it is capable of being proportioned for dimes, quarters or in fact any denomination of money, or rather currency.

If a dime should be inserted in the present machine, it could readily pass through the throat device 3, down the chute sections 7, 3 and 9, and by reason of the fact that in a starting or normal position the rocking plate 22, is always in the Fig. 4, position, the dime would not be arrested by the withdrawn studs 25, and the projected studs 23, are spaced far enough apart to permit a dime to pass through or between them. Thus the dime would discharge at- 10, and as the diverter 90, is always in the Fig. 4, position. when the mechanism is in a normal or starting position, the dime would be diverted into the return receptacle 93, which is accessible to thepurchaser. This would all occur before the purchaser could operate the usual turn knob B, with which devices of this character are equipped. However, suppose the purchaser, after de'-, positing a dime, turned the knob B, in a clockwise direction with a view of causing a vending operation, which is the only way it can be turned by reason of the check pawl 79, engaging the arresting notch 98, then, and in that event, a movement would result which I will next describe. v v v The cam 35 would be turned from the Fig. 1 to the Fig. 2, position, and as nothing would be interposed between the detection stud 53 and the back wall of the coin chute, this stud 53 would be free. to enter the chute to the fullest extent under the act-ion of s'pring52. Such movement would (Fig. 9) cause arm 50 to move toward base-19 and lug 75 would move the break-joint pawl A, to firmly engage the periphery of cam 35 and'thereby cause the end 69 to enter notch 98, and as abutment 99 engaged end 69, a further movement of the cam 35 would break the break-joint pawl into the Fig. 2, position thereby locking the sections 64 and 66, and preventing further rotative movement of cam 35. The upper end of section 64, has a flattened portion 64 that engages the bight 66, of section 66, as clearly shown in Fig. 2. As this movement is being effected and arrested, arm 108 (Fig. 10) rides onto the abutment portion 113, tensioning the spring 114 and thus resists such movement thereby taking much of what would otherwise be a strain subjection from the break-joint pawl. I As the knob is released, recoil of spring 114 quickly restores the parts from the Fig. 2, to the Fig. 1, position, with the arms 108 and 110 in the full line postion in Fig; 10.

In this arrested movement of the mecharise, t e am tud. 39 vealahave moved. out

of engagement with cam 42, and into the 2, position, thereby releasing lever l0 for movement by spring 43, into an upward position as far as slotted arm 4-9 would permit. This would cause the end 1-7, of lever 10, to slide to the outer end of slot 48, as shown. in Fig. 5, thereby rocking plate 22 from the Fig. 1 to the Fig. 5. position, wherein the upper studs 25 would be projected into the chute and the lower studs withdrawn. Should the purchaser deposit a dime and turn knob B before the dime had reacied point in its decent adjacent the plate 22, the above operation would take place even if the studs 25 were projected into the coin chute thereby arresting the dime before the latter reached plate 22. In the following restoring movement, above described, the plate 22 would be restored to the Fig. 1, position, thereby releasing the dime for gravity passage between studs 23, and out through the discharge end 10, as will now be clear.

Suppose a ferrous entity were deposited, would be attracted by the magnet poles l0 and shifted from its path down section 8, into discharge section 11 and out through dischargeend 12, as shown in F 13, and would never reach the detecting mechanism. The non-ferrous strip l7, would prevent the ferrous entity from freezing to the magnet poles 1 6.

Now it will be assumed that a slug had been inserted having a central perfo 'ation as shown in 15. If this slug was of the same diameter as a nickel, and of non-ferrous metal, it would descend in the coin chute into engagement with studs 23 and would be arrested thereby in a position for detection. and the resulting rejectionwillnow be described.

Assuming that such perforated slug descended to the position shown in Fig. 7, and was arrested by studs 23, it will be seen that the perforation would be centered with respect to the detection stud 53 (Fig. 9). Thus, the operation would be much the same as was described in connection with movement of the parts when a dime was inserted. By turning the knob B clockwise, the breakoint pawl would ride down the vale 10.3 thereby ermitting spring 52 to move arm 50 toward liase 19 and cause detection stud 53 to enter the coin chute. As the opening in the slug would not arrest movement of stud 53, the break-joint pawl end 69 would ride into notch 98 and engage terminal 99 and further clockwise movement of cam would cause the pawl to break at its joint as shown in Fig.2, and arrest further movement of the cam. I As the knob B was released by the purchaser, the parts would be restored to the Fig. 1 ,'position, whereupon the plate 22 would be rockedto the same position. However, in movement of the parts to the Fig. 2, position, the plate; 22' would be rocked to the Fig. 4, po ition, thereby releasing the slug just" as soon as the stud 53'had been slightly with drawn, or, in some adjustments, and fact in most adjustments, the stud 53 would never enter the coin chute far enough to project into the perforation in the slug. Thus, in the latter event, just as soon as the plate 22 was rocked to the Fig. 4, position, the slug would be released and would be shifted by the diverter 90, into the pocket 93. The stud 53 is, as heretofore explained, adjustable in arm in accordance with the extent to which it should be projected into the coin chute.

I will next describe the operation which takes place when a nickel or entity of genuine character is inserted into the chute and a vending operation takes place.

When a genuine coin of prescribed denomination has been inserted into the coin chute it will descend therein and be arrested by studs 23, in the position shown in Figs. 4; and 7 Rotative movement of knob B in a clockwise direction will permit break-joint pawl, after riding over peak 102, to descend vale 103, and on this movement, arm 50 will project stud 53 into engagement with the arrested nickel thereby arresting further inward movement of arm 50. Of course, the parts are so timed that studs 23 will not be withdrawn from the coin chute until stud 53 has engaged and held the nickel for a momentary period. l he interposition of the nickel between stud 53 and the back wall of the coin chute prevents arm 50 from moving toward base 19 far enough to cause bell crank 59 to move the break-joint pawl end 69, into said arresting notch 98. Therefore, instead of said end 69 entering said notch and abutting against terminal99, thereof, and arresting movement of cam 35, as it does when a perforated slug or a dime or a nickle worn too thin, are inserted, the

said end 69 rides over said notch 98 and does not engage it. Thus, detection has been accomplished showing that the entity acted upon is the right thickness, and hence, a vending operation must take place. As end 69 passes over notch 98, it rides on operating hill 104, of cam 35 and this causes a clockwise movement of'the break-joint pawl which, viewing Fig. 1, causes arm 50 to move outwardly away from base 19, and thereby released thedetected nickel for discharge from the coin chute. As the break-joint pawl has passed the arresting notch, there is nothing to prevent the knob B from being turned a full revolution to complete a vending operation.

It will ofcourse be understood that before or when the parts have reached the Fig. 3, position, stud 39 will have released cam 42 andlever 4.0 will have been elevated by spring 4-3, thereby tilting plate 22 into the Fig. 5, position, thus to remain until stud 39 again engages cam 42, and lowers lever 40. The upward and downward thrust of the end 47, slot -18, of arm 49, causes rocking ,7

ment of plate 22 and the guide pins 28 and 31, l mit any vertical movement thereof, as Wlll now be clear.

As the cam is turned, it will be'seen that check pawl 79, has ridden upwardly on vale ine coin into the coin box 92-. This downward movement of rod 83, also moves arm 95, of the counter, downwardly, which thus constitutes one portion of actuation thereof. When the cam 35 is advanced far enough so that the check pawl 79, rides inwardly on vale 103,

then, rod 8-3 is lifted or moved upwardly and the counter is finally advanced to indicate that a. vending operation has been effected. As it requires first a downward and then an upward movement of arm 95 to register a counting advance, it will be clear that the counter is never thus operated on a partial or arrested movementof cam 85.

Reverting to the combined braking" and returning means shown in F 10, it will be clear that as the cam 35 is advanced and the check pawl 79 is riding on the ra chet portion, arm 108 will be riding on arm 110, in a contra-clockwise direction, viewing Fig. 10, and after the arm 108 has been elevated out of contact with arm 110, the latter is instantly returned by spring 11% and the abutment 113 is brought .into a position to yielding arrest the cam 35, which has now been returned to normal.

Thus it will be seen that the check pawl 79, is positively effective in preventing retractive or contra-cloclrwise movement of the cam 35, viewing Fig. 1, and that the returning means yieldingly resists clockwise movement of said cam 35 from a normal or starting position and returns it to such position from a. relatively slight advance therefrom.

As heretofore stated, sprin 73 is connect-- ed at its opposite ends to yieldingly maintain pawl 79 and break-joint pawl A, in engagement with the cam wheel 35, and one spring is capable of performing these two functions, it is thus employed. However, spring 7 3 is of such lighter tension than spring 52 as to make the latter dominant and primary.

It is believed that the device of this invention will be fully understood from the foregoing description and while I have herein shown one specific form of the invention, I do notwish to be limited thereto except for such limitations as the claims may import.

I claim 1. In a coin controlled mechanism, a coin chute adapted to receive a plurality of superimposed genuine ancl spurious entities, a

rocking entity controlling frame having a lower set of studs for arresting an entity in a detection position and an upper set of studs for arresting the remaining entities from entering a. detection position, adetection device movable into a detection position with respect to a correspondingly positioned entity to determine the characterof the latter, and means for rocking said frame to alternately dispose said sets of studs in arresting positions in said chute. p

2. In a coin controlled mechanism, a'coin chute adapted to receive entities, a rocking entity controlling plate having sets of entity arresting studs, one set of studs being spaced apart to arrest an entity of a diameter less than the prescribed diameter and the remaining set being spaced apart to permit passage of such smaller diameter entity and close enough to arrest an entity of prescribed diameter, means for rocking said plate to dispose either set of studs in an arresting position'in said chute, and detection means operating against an arrested entity of prescribed diameter.

3. In a coin controlled mechanism, a coin chute for receiving'entities, an entity controlling device' for temporarily arresting an entity ina detection position in'said chute, detectio-nmea-ns movable into said chute a predetermined distance into momentary engagement with an entity of prescribed thickness or moving into said chute'butnotengaging a perforated or too thin entity, and

means for actuating said device to release the arrested entity prior to release of a genume entity by sa d ClQVlCB toprevent a vend ing operation except when a coin of normal thic'kness is deposited in the chute.

4. In a coin controlled mechanism, a coin chute for entities, a floating, rocking plate having upper and lower sets of entity arresting studs adapted alternately to be projected into said chute" as saidpl'ate is rocked, tulcrum guide'pins for giiidingsaid plate inits rocking movement, a spring normally acting to move said plate toward said chute, a slotted arm fixed to said plate and'projecting lat erally of the plane thereof, a lever s'lidable in said slotted arm and being actuated to impart thrusts to said platein different directions in the plane of'said plate to rock the latter into different entity arresting positions, and means for detecting an entity while the latter arrested by said lower set of studs.

5. In a coin'controlled mechanism, a coin chute adaptedto receive an entity for-thickness detection thereof preliminary to a vending or non-vending operation, means for arresting an entity in a detection position in saidchute, a spring actuated detector arm having a detector st ud movable into said chute for engagement with an entity of the prescribed thickness, 'a' master cam having an arresting notch, a break-joint pawl actuated by said armto engage said pawl with said cam" and shifting said pawl into said notch to break said pawl and causethelatter to arrest vending movement of said cam when a perforated or too thin entity permits said stud to enter too far into said chute, or holding said pawl free from said notch on engagement of said stud with a normal thickness entity thereby permitting vending movement of said cam.

6. In a coin controlled mechanism, a coin chute adapted to receive entities, means for arresting an entity in said chute in a detection position, a spring actuated detection arm provided with a detection stud adapted to enter said chute, a master cam provided with a pawl arresting notch, a pawl operatively connected with and urged by said arm into engagement with said cam, said cam having a vale permitting movement of said stud into said chute for engagement with a normal thickness entity to prevent said pawl from engaging said notch or permitting further movementof said stud toward a too thin or perforated arresting entity to permit said pawl to engage said notch and prevent a vending operation, and means for automatically restoring the parts to a normal position from a partial or non-vending position.

7. In a coin controlled mechanism, a counter, a coin chute for entities provided with adischarge end, entity arresting and detecting mechanism for said chute, a. diverter below said discharge end for diverting spurious entities in one direction and genuine entities in another direction,'a check pawl for operating said counter and diverter, and a master cam having a series of ratchet teeth for engagement with said checkpawl to prevent retractive movement of said cam, and said cam having hill and vale portions for actuating said check pawl to operate said counterand diverter.

8. Ina coin controlled mechanism, a coin chute adapted to receive entities, means for arresting an entity in said chute for detection purposes, means for detecting spurious from genuine entities while the entity is arrested in said chute, a pawl connected with said means to operate the latter or be operated thereby, a master cam engaging said pawl, said cam having a portion permitting operation of said pawl by said means responsive to a spurious entity for arresting a vending operation or operating said pawl responsive to a genuine entity to permit a vending operation, and said cam having portions for causing said pawl to operate said means to retract the latter.

9. In a coin controlled mechanism, a coin chute adapted to receive entities, means for arresting an entity in said chute for detection purposes and then releasing such entity, means for detecting spurious from genuine entities while the entity is arrested in said chute, a device connected with said means to operate the latter or be operated thereby, and an element engaging said device and having a portionpermitting operation of said device by said means responsive to a spurious entity for arresting a vending operation or operating said device responsive to a genuine entity to permit a vend ng operatlon.-

In witness whereof, I have hereunto set
