This invention relates to improvements in coin selecting devices which may be used withcoin actuated mechanisms.

'I'he general object of the invention is to provide an improved coin selector device which will separate spurious coins, slugs or other objects from good coins of the denomination intended to actuate the device with which it is associated.

pther objects and the advantages of this invention will be apparent from the following description taken in connection with the accompanying drawings wherein:

Fig. 7 is a section taken on line 1 1 of Fig. 5; and,

Fig. 8 is an elevation showing a detail.

Referring to the drawings by reference characters I haveA indicated my improved coin selector generally at Ill. The device I0 is especially adapted for use in combination with a coin actuated mechanism, wherein two coins of different denominations are required to actuate the mechanism which in this instance are a dime and a nickel. The present invention is an improvement over that shown in application Serial No. 617,356, led June 15, 1932, by William L Gilchrist and Wiuiam H. Hoofnagie.

As shown the device I0 comprises a nickel selecting unit I2 and a dime selecting unit I3. The nickelselecting unit I2 comprises a base member i4 having a cover plate I5 secured there- .40 to by screws I6 and which is retained in` spaced relation to the base I4 by raised portions on the base such as indicated at I1 toform a chamber I8. The base I4 and the cover plate I5 are made of non-ferrous metal and are preferably die cast. Adjacent the top'of the device I4 I provide an entrance raceway 20 which is formed by a pair of spaced rearwardly and downwardly inclined guide portions 2I and 22. The entrance raceway 20 is adapted to direct coins into a forwardly and downwardly inclined raceway 23 which is formed by a pair of spaced -guide portions 24 and 25. The raceway 23 is adapted to direct coins into a vertical raceway 26 which on the forward side includes a guide portion 21 which includes a 5 5 shoulder 21'.

A portion of the bottom of the raceway 23 is formed by an upper face of a b ar magnet 281 which at its forward end terminates at the juncture of the raceway 23 and the raceway 26 in a rounded end portion 29. The raceway 26 communicates with a raceway 30 which includes a rearwardly curved section 3I and a straight rearwardly and downwardly inclined section 32. 'Ihe lower side of the curved section 3I of the raceway 30 is formed by a guide portion 33 and the upper side is formed by a guide portion 34 which has a` forward face 34 and the lower portion ofthe straight section 32 is formed by a guide portion 35. The guide portions 33 and 35 are preferably bevelled downward towards the cover plate as indicated at 36 (see Fig. 2) to urge coins towards a magnet to be presently described.

Good nickels upon leaving the raceway 30 pass through a raceway'31 and enter a vertical exit raceway 38. The bottom of the raceway 31 is formed by avselector device 39 which includes a dividing point 4Il. The selector device 39 is pivotally mounted on the base I 4, as indicated at 40',- so that it may be swung and adjusted and is adapted to be firmly retained in an adjusted position by a screw 40".

Spurious coins upon leaving the raceway 30 fall into a downwardly and forwardly inclined raceway 4I which directs them into a vertical raceway 42. The bottom of the raceway 4I is formed by a guide portion 43 and the forward side of the raceway 42 is formed by a guide por-v tion 44. y

Adjacentthe juncture of the raceways 23 and 26 I provide a rearwardly and downwardly inclined raceway 45 the top of which is formed by a guide portion 46 and the bottom by a guide portion-41 with the guide portion terminating adjacent the curved portion 29 of the magnet 28. The raceway 23 directs ferrous coins into a downwardly and forwardly inclined raceway 48 one side of which is formed by a guide portion 48 and the other side by a guide portion 50.

Adjacent the lower end of the raceway -48 I` provide an aperture 5I in the cover plate I5 (see Fig. 4). Furthermore, adjacent the lower end of the raceway 48 I provide an abutment portion 52 which1its an aperture in the cover plate I5 and'which includes an inclined surface 53 which adapted to direct coins out oi.' the device I2 through the aperture 5I in the cover plate I5.

Intermediate the length of the entrance raceway 20 I provide an elongated aperture 54 in vplate I5. The plate clined rearwardly and the base I4 and in the raceway 23 I provide a similar aperture 55 in the base.

Adjacent the straight section 32 of the raceway 30 I provide a horse shoe magnet 56, the poles 51 and 58 of which are arranged in holes in a plate 58a which ts in a slot 58b in the cover 58a has'end ribs 58c and side ribs 58d thereon. The poles 51 and 58 are positioned across the raceway 30 at approximately right angles thereto with the faces of the poles and the face of the plate 58B flush with the inner face of the base |4. Opposite the magnet 56 I provide a similar horse shoe `magnet 59, similarly mounted and with the poles 60 and 6I positioned across the raceway 30 similar to the poles of theY magnet 56. The faces of the poles 60 and 6| and the plates 58a thereof are fiush with the inner face of the cover plate I5 as clearly shown in Fig. 3. The poles of the magnets 56 and 59 are positioned in opposed relation, that is the north pole of the magnet 56 is opposite the south pole of the magnet 59 and vice versa.

The dime selecting unit I3 like the nickel selecting unit I2 comprises a base 62 having a cover .plate 63 thereon which is retained in spaced relation from' the base by raised portions on the base such as indicated at 64 to form a chamber 65. The base 62 and the cover plate 63 are made of non-ferrous metal and are preferably die cast. Adjacent the top of the device I3 I provide a rearwardly curved entrance raceway 66 which is formed by a pair of spaced guide portions 61 and 68. Themraceway 66 directs coins into a rearwaidly and downwardly inclined raceway 69 the top of which is formed by a guide portion 10 and the bottom by a guide portion 1|. The raceway 69 directs coins into a raceway 12 which is indownwardly at a sharper slope than the raceway 69 and one side of which is formed by a guide portion 13.

Adjacent the juncture of the raceway 69 and the raceway 12 I provide a magnet member v14 the end of which at the juncture of the raceways 69 and 12 is rounded as at 15 and a portion of the magnet 14 adjacent the juncture of the raceways 69 and 12 forms a part of the bottom of the raceway 69, as at 16.v The raceway 12 directs coins into a downwardly and forwardly inclined raceway 11 the sides of which are formed by spaced guide portions 18 and 19. The guide portion 19 includes a Shoulder 19.

The raceway 11 communicates with a raceway which includes a forwardly curved section 8| and a straight', forwardly inclined, section 82. One side of the curved section 8| of the raceway 80 is formed by a'guide portion 83 and the opposite side by aguide portion the straight section is formed while the bottom is tion 86. The guide portion tion 8| of the raceway 80 is towards the cover plate as indicated at 84' (see Fig. '1). Ciood dimes upon leaving the raceway 80 fall into a forwardly and downwardlyinclined by a guide portion 84 of the curved secracewayY 81 which directs them into a verticalexit raceway 88. The bottom of the raceway 81 is formed byV a guide portion theraceway 88 is formed by a guide portion |00. The front of the raceway 88 is formed by a guide member |0I which is separate from the base 62 and is loosely mounted on the base by rivets |02. By loosely mounting the guide member |0| coins striking this guide member will be prevented from rebounding therefrom over the separating point |25 into the coin chute |03.

84 and the top of formed by a guide porpreferably bevelle'd 99 and the rear of A Some spurious coins upon leaving the raceway 80 fall into a rearwardly and downwardly inclined raceway |03 which directs them into a vertical exit raceway |04. The bottom of the raceway |03 is formed by a guide portion |05 and the rear of the raceway |04 is formed by a guide portion |06.

Other spurious coins upon leaving the raceway 80 strike a selector device |01 and run down this selector device and fall downward and strike a selector device |08 and are directed into a raceway |03. Each of the selector devices |01 and |08 is pivotally mounted on the base 62 as indicatedat |09 and ||9 so that they may be adjusted and are adapted to be firmly clamped in adjusted positions by screws I I0.

Adjacent the juncture of the raceway 69 and 12 I provide a forwardly and downwardly inclined raceway I2 the top of which is formed by a, guide portion ||3 and the bottom by a guide portion ||4, and a portion of the bottom of the magnet 14 as indicated at I|5. The raceway ||2 directs ferrous coins into a rearwardly and downwardly inclined raceway ||6 the forward side of which is formed by a guide portion ||1 and the rear side by a guide portion I |8.

Adjacent the straight section 82 of the raceway 80 I provide a horse shoe magnet |20 which is set in a plate |20a which is similar to the plate 58e, previously described. The poles |2| and |22 of the magnet |20 are positioned across the raceway 80 at approximatelyy right angles thereto with thev faces of the poles flush with the inner surface of the cover plate 63 as clearly shown in Fig. '7. Set into the base 62 opposite the magnet |20 I provide an armature plate |23, theinner face of which is flush with the inner face of the base and-the outer face is ush with the outer face of the base.

When the device I0 is operatively assembled the nickel unit I2 and the dime unit I3 are positioned with their respective bases back to back and are retained in this position in any desired manner. When the units I2 and I3 are thus assembled the armature plate |23 of the unit I3 vcompletely covers the aperture the unit I2 and partially covers the aperture 55 in the base of the unit I2, as clearly shown in Fig. 1.

Good nickels entering the entrance raceway 20 of the nickel unit I2 pass downward through the raceway into the raceway 23 thence into and through the raceway 26 and strike the forward face 34 0f the guide portion 34 and then pass beneath the shoulder 21' thus before they pass into the raceway 30. As a nickel passes the aperture 54 in the raceway 20 and the aperture 55 in the raceway 23 it is slowed down somewhat by the flux eld produced by the magnet |20. In the raceway 30 the nickel passes between the poles of the magnets 56 and 59 and the flux field again alters the velocity of the coin according to its magnetic contents so that@ good nickel enters the raceway whence it passes into the exit raceway 38.

Iron and steel disks entering the raceway 20 pass downwardly therein into the raceway 23 54 in the base of being slowed down through which they roll to the rounded end 29 of CSi f' roll into the raceway 12 Some other non-ferrous spurious disks after passing through the entrance raceway 20 pass x.through the raceways 23 and 26 into the raceway 30. As these spurious disks pass through the magnetic field between the poles of the magnets 56 and 59 their velocity is decreased to such an extent that as they leave the raceway 30 they do not have suicient speed topass over the dividing point 40 of the selector/39 'so therefore fall into the raceway 4| whichdirects them intothe raceway 42.

The-raceway v38 into which good' nickels are directed may communicate with a suitable coin chute which in turn will direct the nickels to the coin actuated mechanism with which the device is associated. spurious coins leaving the raceways 42'and 48 may be directed into suitable coin lchutes which may either direct the spurious disks 'out of the machine with which the device is associated or into a suitable receiver.

Good dimes upon entering the entrance raceway 66 of the dime unit I3 pass therethrough into the raceway 68 which directs them into the raceway 12 from which they pass into the raceway 11 which directs them into the raceway 80. As the dimes pass from the raceway 11 into the raceway 80 they strike the shoulder 19' which momentarily stops them causing them to' joggle so that each coin enters the curved section 8| of the raceway 80 at approximately .the same speed. As a dime passes between the poles of the magnet |20 and the armature plate |23 it passes through the flux field between the poles |2| and |22 and the armature plate |23 and is retarded suiiiciently so that in its fall it does not strike the dividing point |24 of the selector |01 but does not retard it suiiciently to cause it to strike the dividing point |25 ofthe selector |08. 'I'hus the retardation of the dime is such that after leaving the raceway l8|! it falls into the raceway 81 which directs it into the exit raceway 88. y Iron and steel disks entering the entrance raceway 66 pass therethrough into the raceway 69. which directs them into the, raceway 12. As they the magnet 14 attracts them into the raceway 2 through which they roll into the raceway I6 down which they fall into the raceway |03 which directs them into the raceway |04.

Some other non-ferrous spurious disks after entering the entrance raceway 66 are directed through the raceways 69, 12 and 11 into the raceway 80. As these spurious disks pass through the magnetic field between the poles of the .magnet |20 and the armature plate |23 their velocity is retarded sufliciently to cause them to fall straight downward into the raceway |03 and thence into the raceway |04.

'I'he raceway 88 into which good dimes are directed may communicate with a suitable coin chute which in turn will direct the dimes to the coin actuated .mechanism with which the device is associated. Spurious coins leaving the rac'eway |04 may be directed into suitable coin chutes which may either direct the spurious disks out of the. machine with which the device isassociated or into a suitable receiver. l

In Fig. 5 I show a sizing device which is indicated generally at |25. This sizing device includes a chute |26 through which coins pass before entering the upper end of chute 66. A member |21 is pivoted as at |28 and is provided with a weighted portion |29 so that the member normally assumes the position shown in Fig. 8. A small light weight coin entering the chute |26 will not rock the member |21 and consequently will pass over the chute 66 and over the separating point |30 which is oil/the tip of the chute 61. Thus, this small light weight coin' will not enter the chute I66. A proper coin however will pivot the member |21 about its pivot |28 and will cause this proper-sized coin to enter the chute 66 and thus pass to the coin selecting mechanism.

From the foregoing description it will be apparent that I have provided a novel coin selecting device which is simple in construction and highly emcient in use;
