Gust Poulas, Cleveland, Ohio, assignor of forty per cent to Theodore Bibicos, Cleveland, Ohio Application December 21, 1933, Serial No. 703,393 1 Claim. (Cl. 194-100) This invention relates to an improvement in fraud preventative devices over my previous Patent #1,919,478 and my recent patent application under Serial #691,334--filed September 28, 1933, in that it simplifies the constructions shown in the previous patent and patent application and at the same time eliminates slugs of various kinds whether magnetic or non-magnetic.

The principal object of the present invention is to prevent the passage through a machine of many types of slug either magnetic or nonmagnetic which is clearly shown in the following specification and its accompanying illustrations, in which:

Fig. 1 is a front elevation of the device which illustrates the passage of coins and different types of slugs.

Fig. 2 is an elevation cover.

Fig. 3 is a side elevation taken on lines 3-3 of Fig. 1.

Fig. 4 is a side elevation partly in section taken on lines 4--4 of Fig. 1.

Fig. 5 is a side elevation partly in section taken on lines 5-5 of Fig. 1.

Fig. 6 is a fragmentary portion showing a modified form of the coin passage and adjustable coin buffer.

Fig. 7 is a side elevation of Fig. 6.

Fig. 8 is a diagram showing the line of the coin.

Fig. 9 is a diagram showing the line of the nonmagnetic slugs.

Fig. 10 is a diagram magnetic slug.

Referring to the drawing: the coin mechanism back plate 10 has mounted thereon a coin inlet casing 11 in the upper corner by means of screws 12. A coin slide 13 is mounted on an angle below said coin inlet 11 and retained in position by a slotted adjustable arm 14 with washer 15 and screw 16, said arm being riveted to coin slide 13.

A magnetic metal guide 1'7 extends over the lower portion of coin slide 13 and is anchored below said coin slide 13 to the back plate 10 by means of a bolt 18 and nut 19. This guide has aface 53 below the slide 13,on which face good coins will rebound.

A pivot arm 20 is attached by bolt 21 and washer 22 to back plate 10; a movable buffer plate 23 is pivoted at 24 to pivot arm 20. A coin discharging or outlet slide 25 mounted in the lower opposite corner is adjustable beside the grooved guide 26 by means of the slotted slide 27, washer 28 and. screw 29 engaging the back plate 10, said slide of the coin mechanism showing the line of the being attached to the .coin discharging slide 25 by means of screws in apertures 26a.

A roller 30 is mounted on a bolt 31 between lug 32 and the back plate 10; a guide 33 is also attached to the coin discharging slide 25 by rivets 5 330., said guide extending within the'angle 34 of the magnetic guide 17.

Pivotally attached to the coin discharging slide 25 by a pin 35 is a weighted swinging door 36, the weights 37 being retained on arm 38 by a nut 39. 10

A plurality of lugs 40 in the corners of said back plate 10 have screw holes 41 by which the cover 42 is attached by means of locking bolts.

Coin pockets or drawers 43 and 44 are situated below the coin mechanism in such manner as to 15 receive all coins 45 or slugs 46 and 46m into their respective drawers or pockets.

The cover 42 is cut out at 47 to receive the coin inlet casing 11 and has a plurality of apertures 49 in the corners of said cover through which the 20 looking bolts attach the cover to the back plate 10, and the flanged sides 50 of said cover project over the lugs 40 on the back plate 10 thus forming a coin mechanism box. The nut 19 and bolt 18 of the magnetic guide 1'7 project through an aperture 51 in the cover 42. Flange 50 is bent upward at 52 to prevent the slugs from stopping within the mechanism box.

In operation a good coin 45 is inserted in the coin inlet receptacle 11 through which it passes into the coin slide 13 thence downward to the angular face 53 of the magnetic guide 17 with such force as to cause it to bounce upward in an are against the door 36 which swings open thus permitting the coin 45 to drop downthrough the coin slide 25 and into the drawer or pocket 43.

If a slug such as glass or brass is inserted in the machine, it will bound higher than a proper 3 coin, and will bound from the surface 53 up against the pivoted buffer 23 which will yield under the impact and thus deaden the rebound to such an extent that such a slug will drop substantially straight down into the slug pocket 44, or if it should strike the gate 36 it will be at such an acute angle that it will not open it but will fall into the slug pocket likewise.

On the other hand, a non-magnetic slug 46 not having the springiness or resilience of the coin 45 or magnetic slug 460., does not spring upward to the height that the coin does, but drops down- 50 ward to the pocket, or drawer 44. If the slug should show a little springiness, the roller 30 assists the downward movement of the slug and prevents its entrance into the coin'dispensing slide 25. 55

The magnetic slug 46a slides downward at a lessening speed due to the magnetic guide 17 and does not spring at all but drops down into the drawer or pocket 44.

The modification shownin Figs. 6 and '7 shows another method of retarding the upward spring of the coin by the use of the slotted coin buffer 54 which could be used instead of the bufie r 23 and which stops the. upward spring of the coin and causes it to drop back within the coin dispensingv slide 25a, this coin buffer is adjustable by means of the slot 55, Washer 56 and screw 57 to the height desired for mosteflicient action.

I claim:

The combination with a casing having an inlet coin slide and an outlet coin slide, said slides being located opposite each other, of an anvil block located below the inlet side, to cause the rebound of coins to the outlet slide, a pivoted gate at the inlet to the outlet slide, arranged to .be struck and opened by a coin after it rebounds from the anvil block, a buffer plate between the anvil block andv said gate, in a position above the line of movement of a normal coin from the block to the gate, and a swinging link pivoted to the casing and to the buffer plate and suspending the latter in position to deflect abnormal coin substitutes downwardly beside the gate.

GUST POULAS.
