My invention is a slug ejector for coin machines, adapted to either discharge or to return so-called slugs or other devices which a person may attempt to ass for a coin.

An object of my invention is theconstruction of a slu ejector for use with coin con trolled machlnes adapted to throw out coins which have magnetic properties, those having smooth faces and rims and those having holes in the center.

Another object of my invention is to construct a slug ejector which will properly handle a legitimate coin to operate the'coin controlled machine and will return the slugs or like constructions to the operator of the machine.

A further object of my invention is a slug ejector in which coins having magnetic properties are discharged from the chute in which they are inserted and have means by which slugs having magnetic properties are forced into engagement with the magnet and thereby guided into a discharge chute for mag netic slugs.

A still further object is the construction of a slidable type of coin block containing a pocket for coins and having means in said block to grip and hold coins by the head or rim around the edge such anism failing to hol smooti surface slugs and allowing these to drop in the travel of the block, into a slug ejecting chute; The machine is provided with 'means" for disengaging the coin holding device and allowing F5 coins to drop in a coin chute.

Slugs which have a bead on the edge and a hole in the center are disengaged from the holding device after passage of the slug chute and are retained by a stopping device engaging the central aperture, thereby limiting the movementof the coin block so that it is not positioned over the coin chute. On the return movement the gripping device fails to engage such slug with a rim and a 5 hole as these have been slightly dro ped and such slugs are moved in the slug c ute and discharged.

Another object of my invention is in providin a delay "action or a slight stop when 0 the sliding coin block is positioned over the upping mech 7-7 of Fig. 5 in the direction of the arrows;

ever, has in addition means to institute the A positive ejection of a slug and means to prevent insertion of coins or slugs in the coin 1 block before same is properly positioned.

Other detail features will be apparent from the description.

The stationary housing for the slug ejector mechanism is constructed substantially as follows:

The housing is designated generally by the numeral 1, being preferably in two longitudinal halves formed substantially the same and attached together by screws or the like. The upper portion 2 contains an insert coin chute 3, this chute havingan inclined passage 4 followed by a substantially vertical drop passage 5. A permanent magnet 6 is mounted on a lug 7 and a chute 8 for slugs having magnetic properties is positioned below the magnet, discharging at the front of the machine. A guideway designated generally by the numeral 9 extends lengthwise of the housing or block and preferably has a plug 10 formin a closure for the forward end, this plug eing attached by a set screw 11 or the like. I

A slug chute 12 is formed in the housing back of the coin drop passage 5 and still further rearwardly. a coin chute 13 is formed. An insert plate 14 preferably of hard metal is positioned below the coin drop passage 5 and extends upwardly above the base 15 of the guideway 9. A wear plate 16 is inserted adjacent the slug chute and its upper surface is in alinement with the base 15 of the guideway. One side of the guideway is provided with a lon itudinal passage 17 and has a slot 18 exten ing part of the length of the housing and extending into the passage 17. The upper portion of the guideway has bearing surfaces 19 for the coin block as hereunder described and with a roof section 20 located above the top of any coin which might be inserted in the machine.

The side portions 21 of the guideway are to accommodate holding or retaining devices for the coins as hereunder described. The

housin is supported by lugs 22 or the like at the ase which may be secured to a coin controlled machine of any suitable type. The sides of thehousing are provided with forward cam surfaces 23 and rearward cam surfaces 24, these being preferably hard metal inserts into the side portions 21 of the guideway for controlling the operation of the suspending fingers or dogs for'coins as hereunder set forth in detail. A

A recess 25 is formed in one of the housmg sections and a lever 26 is ivoted on a vertical pin 27. This lever as a small roller 28 at one end and a compression spring 29 positioned between such end of the lever having the roller and the side of the housing. A slidable pin 30 is fitted through an aperture 31 in the lever, this pin being normally pressed towards the guideway by the leaf spring slot 32.

The housing sections have a socket 33 formed in each half and aslug ejector pin 34 extends downwardly-into the guideway.

psection 45 on one side.

32, and passing through the This pin has a head 35 resting in the bottom in each half of the housing and having a compression spring normally forcing same into the coin passage5 as shown in Fig. 5. The pin has a depending arm 41 go engage the coin block as hereunder set orth.

The coin block is designated generally by the numeral 42 and has a web section 43, an upper flangesection 44 and a lower flange The block has a slight incline 46 at the rearward end, 47 at the forward end and 48 and 49 at each end of the coin pocket 50 which extend vertically through the coin block. The web of the block is provided with a longitudinal groove 51 at the bottom, this groove sliding over the insert plate 14. A pair of lateral .sage and have a pair of dogs or fingers 53 mounted therein, these being swivelled on pins 54. The gripping ends 55 of the dogs extend into the coin pocket 50, the outer ends 56 extend into the side portions 21 of the guideway and are positioned to engage the stationary cams 23 and 24. The lower flange 45 is provided with a screw threaded hole 57 for a pin as hereunder set forth.

The operating mechanism for the slug ejector is constructed substantially as follows, having reference particularly to Figs. 1, 2 and 4:

This illustrates the pausing motion device. Anoperating arm 58 is-mounted on a bolt 59 which is threaded into a lug 60 extending laterally from one side of the housing. A coiled spring 61 secured respectively to the operating arm and to the lug is normallyextends through this U shaped slot throughthe longitudinal slot 18 and is screw threaded into the hole 57 in the flange 45 of the coin block.

The manner of operation of my slug ejector is substantially as follows:

Fresuming firstthat a slug having magnetic properties is inserted in the coin chute 3, this is guided by the inclined portion of the passage 4'so that the edge'of the slug is drawn against the magnet 6 substantially at the pole pieces where the magnetic flux is strongest. The magnet thus attracts the slug and causes it to follow the path 8 for slugs having magnetic properties. It does not matter whether the slug is gently placed in the coin chute or vigorously forced therein as in both cases the slug is sure to be thrown against the magnet and brought into actual contact with same.

If a legitimate coin is inserted in the coin chute this coin having no magnetic properties follows the inclined path 4 and drops vertically into the lower drop portion 5 of the passage and if the coin block should be in a rearward position the coin is retained elevated by means of 'thepin 38 which proj ects into the coin drop passage 5. However, when the coin block is in its normal stationary or initial position as shown in Fig. 3,

the coin drops into the coin pocket of the block, the lower edge of the coin resting on the upper edge of the insert plate 14 as indicated in Figs. 3 and 4. In this position the cams 23 hold the dogs 53 so that the grippingends 55 are moved out of contact with the coin. When the operating arm;58 is drawn forward at its upper end the motion is transferred through the pin 66 connected to the flange 45 to the block and slides the block lengthwise of the housing, as the pin slides upwardly in the rearward slots 64 until it is positioned in the adjoining slot.

During the slight motion of the lever the coin block is stationary until the pin 66 enters the forward slot 63' when the motion is continued. The cams 24 on the side of the housing for opening the suspending dogs are positioned to open such dogs when the coin is slightly past the wear insert plate 16. The coin is then freed and drops on the base surface 15 of the guideway and is shoved into the coin chute 13, thereby following such chute into any coin controlled machine.

Presuming a coin having a smooth edge without any bead and without any central perforation or the like is utilized, this coin being non-magnetic, it drops in the same manner as a legitimate coin through the coin chute into the coin ocket of the coin block but as the suspenr ing dogs do not grip such coin, there being no bead, it is carried by the block until the slug rolls ofi the upper edge of the insert plate 14. Just at this edge the upper edge of the slug comes into contact with the pin 34 pressed downwardly by the spring 37, being forcibly thrust downwardly into the slug chute 12. At this particular time the pin 66 is traversing the joined section of the U-shaped slot and the block is held stationary for the moment. Therefore this gives suflicient time, no matter how quickly the operating arm is worked and the coin block slid, for the slug to drop clear of the coin block into the slug chute, as there is always this pause or positive stop in the movement of the coin block.

Presuming a slug non-magnetic and having a central aperture with a bead or rim on the edge is utilized, this falls through the coin chute into the coin pocket of the coin block inthe manner above describedand the gripping dogs engage such slug by the rim carrying it .suspended in the same manner as a legitimate coin, over the coin chute 12 V in the backward movement of the coin block. This slug is however, dropped by the dogs engaging the cam 24 as above described so that it rests on the up er surface of the insert 16 on a level wit the base 15 of the guideway.

The movement, of the coin block rearwardly engages the roller 28 on the lever 26, swinging 'such lever from the position shown in Figs. 7 and 8 to that shown in Fig. 9 and in such action the pin 30 is thrust by means of the spring 32 into the central aperture of a slug as shown in Fig. 9. When a legitimate coin is used however, the spring 32 gives and allows the coin to be thrust further into the coin chute 13. When the pin 30 is engaging a slug this blocks the movement of the machine preventing the block from being moved back any further. The spring 61 will then draw the block forwardly unless the person operating same voluntarily does this and in such action the coin pocket 50 rolls the slug on the upper edge of the insert 16, this being released from the pin 30 by the spring 29 forcing the lever back into its original position of Figs..7 and 8. Such slug therefore drops into the slug chute 12-and is discharged.

It will thus been seen that with my slug ejector I have a device which will throw out slugs having magnetic properties no matter whether they have beads on the edge or not, as these do not get into the machine. Slugs which are smooth surfaced are also readily ejected as they are not retained suspended by the holding mechanism. Slugs which have a central aperture and also 'have a beaded rim are also rejected, such slugs being retained by the device engaging the central aperture and preventing their being positioned over the coin chute and causing their ejection through the slug chute. Legitimate coins however, even if the bead is very much worn are carried through and passed into the coin chute. However, should the bead be entirely eliminated from such coins they ferent prices, or the like, such as set forth.
