Application filed February 24,1980. Serial Io. 430,506.

This invention relates to slug ejectors ada ted for use in connection with coin actuate money changers, vending machines and other like apparatus and has for its general object the provision of certain new and useful improvements on the slug ejector covered by my pending a plication for Letters Patent of the United states led on the 22d day of August, 1927, Serial No. 214,515; and o also by my pending a plication tor Letters Patent of the United dtates filed on the th day of Au ust, 1928, Serial No. 300,645.

A speci c object of the present invention is to provide a slug ejector havin new .and w improved meansto guide coins o a certain denomination to a predetermined destination; to eject ever slug and coin which is heavier or lighter t an a coin of that denomination, and all magnetic slugs 5 and to de- 90 tain certain slugs and ej ect all coins and slugs deposited during such detention.

Other specific objects of the invention will hereinafter appear.

The preferred embodiment ot the invention .2a is illustrated by the accompanying drawings, of which Fig. 1 is a side elevation with one side wall of the casing and one ot the partition plates removed, the movable parts being shown in their normal positions; Fig.'2, a section on the line 2--2 ot Fig. 1; Fig. 3, a view similar to Fig. 1, the operative parts being shown in their actuated positions; and Fig. 4, a fragmentary detail view, partly in section, of the entrance blocking lever and associated parts.

The slug ejector may be vhoused in a suitable casing in which the parallel partition plates 1. and 2, shown clearly by Fig. 2, are mounted.

lThe plates

1 and 2 are held in spaced relation by the guides 3, which form an entrance passageway 4 with which the deposit slot 5 communicates; a coin passageway 6 into which coins are directed and a slug passageway 7 into which slugs are directed.

The apparatus includes a selecting beam 8 pivotally mounted as indicated at 9 in the path of downwardly moving coins and slugs. The beam 8 is supported in the normal position shown by Fig. 1 by the pin l0 extending through the slot 11 in the partition plate. 1. The beam has a curved finger 8a and a normall inclined upper edge 8b to form a track for ownwardly moving coins and slugs. Pivoted at 12 adjacent the deposit slot 5 55 1s the entrance blocking lever 13. This lever has a laterally bevelled head 13a for a purose which will hereinafter appear, and an` inclined edge 13 b-to form a track for down- Wardlymoving coins and slugs. Mounted on the horizontal arm 13o at the lower end of this lever is the roller 14 having peripheral teeth.

To limit the rotation of the blocking lever 13I and roller 14 the invention provides the stop member 15 having a tooth 15a .toengage 65 said roller. This stop member is pivoted at 16 so that it may be held in various positions by the set screw 17 fitting in the arcuate slot 15b.

Pivote'd at 18 below the parts just re- 7 ferred to is the coin passageway gate 19. rIjhe pivot pin 18 extends through the partition plate 1, as shown by Fig. 2, and the beam actuating lever 20 is non-rotatably mounted on this pin on the outside of the partition plate 1. In Figs. 1 and 3, the partition plate 1 has beenremoved and the beam 2O remounted on the pin 18, for convenience in illustration. Tt will be understood that when the parts are assembled for operation, '80 lever 20 will be disposed on the outside o the plate 1 and the other elements above referred to on the inside of said plate, as indicated by Fig. 2.

The gate 19 has a cam 19a normally extending into the slot 21a of the actuating bar 21. This bar is connected to a suitable handle, no t shown, accessible from the exterior of the casing. It is guided in its reciprocatory movement by the

pins

22 and 23 90 carried by the partition plate 1 and extending through slots 2lb and 21o.

Coins of the proper denomination deposited in the ejector are directed tothe coin passageway 6 wh'ch may lead to any desired 95 destination, such as the coin-controlled mechanism of a vending machine, money changer, or the like.

Attention is now invited to Fig. 41 which v illustrates the automatic operation of the 1 parts whereby a proper coin is directed to the coin passageway 6. When such a coin C is inserted in the deposit slot 5, it falls into the entrance passageway 4, rolls down and ofi the inclined edge 13b of the entrance blocking lever 13 and upon the concave finger 8a of the selecting beam 8. Rebounding from said finger, it then rolls down the inclined edge 8b of the selecting beam against the roller 14.

The size of the roller 14 and its disposition with respect to the beam 8 are such that the coin and roller come into Contact at a point below the center of gravity of the coin. When, after such contact, the coin continues to roll in an anti-clockwise direction down the edge of the beam, carrying the roller with it, the roller rotates in a clockwise direction, so that practically no resistance is offered to the free rotation of the coin until the roller strikes the tooth 15a of the stop member 15. `The stop member prevents all further movement of the roller by the coin. Robbed of its' inertia and acted upon by gravity, the coin thereupon moves downwardly, swinging the beam Sinto the position indicated at 8v', and falling oli' the same into the coin passageway 6. The position 8 of the beam is predetermined with respect to coin passageway 6.

The beam 8 is made movable by a proper coin into the position 8 by placing the fulcrum 9 a certain distance from the center of gravity of the beam; and by placing the adfjustable stop member 15 a certain. distance from the fulcrum 9. It will be obvious that rotation of the beam 8 is dependent not only on the weight of the coin, but also upon the distance between the fulcrum 9 and the point on the edge 8b to which the coin is permitted to roll. This distance may be varied by adjusting the stop niember 15.

The movement into the slug passageway 7 of a slug heavier than a coin of the proper Ieo tllenomination will now be described. See 1g. 1. A slug HS appreciably heavier than a proper coin will fall upon and rock the` beam 8 and then strike the roller14 and rebound into the slug passageway 7. The position into which the heavy slug may move the beam is indicated at 8". The exact position into which a certain heavy slug will move the beam will depend upon the weight of that slug. The beam may be rotated considerably more than indicated by the dotted lines 8. The position 8" is predetermined with respect to slug passageway 7.

Now' a slug LS appreciably lighter than a coin of the proper denomination falls upon and rolls down the inclined edge 8b of the selecting beam (Fig. 1) and moves the rollerv 14 into engagement with the stop member 15. Of insuliicient weight to rock the beam, the light slug is therefore `arrested and detained by the beam and roller. The detention of the light slugand the release of the coin is effected by adjustment of. the stop member 15. v

It is very ditlicult to cause the light slug to fall'into the coin passageway 6 by shaking the machine, because the point of contact between the roller 14 is below the center of slug, light slug has a greater tendency to climb the roller than to depress the beam.

The light slug, it will be understood, moves the entrance blocking lever into the position indicated in dottedlines at 13 so that the gravity of the light so that when the ejector is shaken the and the light slug y head 13a of the entrance blocking lever 13 posit slot 5 will be directed by the head 13a into the overflow passageway 24, (Figs. 1 and 4) which may be made to communicate with the slug passageway 7.

When an attempt is made to operate the machine with which the slug ejector is being used, by depressing the operating handle, not shown but hereinabove referred to, the actuating bar 21 is moved@ downwardly. When the bar 21 is moved downwardly, the gate 19 is lirst moved over the coin passageway, and then the beam 20 strikes the pin 10 and rocks the selecting beam 8. The position of the parts before the actuating bar 21 is moved is shown by Fig. 1, the position of the parts after the actuating bar has been moved downwardly is shown by Fig. 3. It will be apparent that the light slug( is not released until the gate 19 is closed, so that the light slug cannot enter the coin passageway 6 and therefore must enter the slug passageway 7.

When-the light slug is released, the lever 13 will be swung back by gravity to the normal position shown by Fig. 1 so that the entrance passageway 4 will automatically be opened.

Means are provided to automatically return the operating handle (not shown), to its normal position, when it is released by the operator, so that the bar 21 is moved to its normal position and thel gate 19 and lever 2O `are permitted to swing from the positions shown by Fig. 1.

Now if a slug MS containing iron is inserted, it will be detained by the magnet M.

Fig. `3 to the positions shown by During the detention of the slug MS by thev N ow if ,the operating handle, not shown, 1:,J

,i l l y y 1,859,725

is actuated, the.parts will'be moved from the positions shown b Fig. 1 to the positions shown by Fig. 3, w ereby the slug MS is swept from the magnet M into the sliig passagewayi 7, and the slu AS is forced upward- 1y on the edge 13b o the blocking lever 13 where it will temporarily be supported by thel linger 8a pf the selecting beam 8. When the parts are permitted to return to the normal positions illustrated by Fig. 1, the fin- -ger 8a releases the slug AS so that it falls upon the edge 8b. If the slug AS is heavier than the proper coin, it will rock the beam 8' into the dotted line position 8 and fall from it into the slug passageway 7 if lighter, it will be detained by the beam 8 and the roller 14,

and thereafter discharged through the slug n passagewa 7 by manualopera-tionofthe parts as hereina ove described;,and if magnetic,

it will not be detained by the magnet M be-V tained by the slug MS and the blocking lever,

and nally released and dropped into the`coin passageway when the parts are manually op-l erated to dispose of the slug MS.
