United States Patent 3,193,075 MONEY-HANDLING DEVICES Anton Okolisehan, St. Louis, and Joseph M. Sehaab, St. Louis County, Mo., assignors to National Rejeetors, Inc, St. Louis, Mo., a corporation of Missouri Filed Mar. 2, 1964, Ser. No. 348,366 13 Claims. (Cl. 194-400) This invention relates to improvements in Money- Handling Devices. More particularly, this invention relates to improvements in devices which can test and sort coins.

It is, therefore, an object of the present invention to provide an improved device which can test and sort coins. I In the testing and sorting of coins, it is customary to separate coins which are made of coin silver from coins or slugs which are made of metals or alloys that have resistivities materially different from the resistivity of coin silver. For example, it is customary to separate coins which are made of coin silver from coins or slugs which are made of copper, zinc, brass, cupronickel, lead, and German silver. In separating coins which are made of coin silver from such coins or slugs, it is customary to provide magnetic flux lines adjacent a runway, and to provide a deflector and a separator adjacent to, but below the level of, the discharge end of that runway. As a copper coin or slug rolls along the runway, the magnetic flux lines will develop eddy currents within that coin or slug which will generate .a magnetic field; and that magnetic field will interact with those magnetic flux lines to reduce the speed of that coin or slug sufliciently to cause it to fall short of the separator, and thus pass to a rejected coin chute. As a zinc, brass, cupronickel, lead or German silver coin or slug rolls along the runway, the magnetic flux lines will develop eddy currents within that coin or slug which will generate a magnetic field; and that magnetic field will interact with those magnetic flux lines and tend to reduce the speed of that coin or slug. However, because of the relatively high resistivities of zinc, brass, cupronickel, lead and German silver, the magnetic field generated by the eddy current in such a coin or slug will not be large enough to cause a material reduction in the speed of that coin or slug. As a result, such a coin or slug will strike the deflector with sufiicient force to cause that coin or slug to rebound back past the separator, and to pass into the rejected coin chute.

As a silver coin rolls along the runway, the magnetic flux lines will develop eddy currents in that coin which will generate a magnetic field; and that magnetic field will interact with those magnetic ilux lines to reduce the speed of that coin sufficiently to enable it to pass between the deflector and separator, and thus pass to an accepted coin chute. As a result silver coins are accepted, whereas copper, zinc, brass, cupronickel, lead and German silver coins or slugs are rejected.

In some instances, however, it is desirable to accept some high resistivity coins as well as silver coins, while rejecting copper, zinc, brass, and lead coins or slugs. Consequently, it would be desirable to provide a coin separator which could accept some high resistivity coins as well as silver coins, but which would reject copper, zinc, brass, and lead coins or slugs. The present invention provides such a coin separator; and it is, therefore, an object of the present invention to provide a coin separator which can accept some high resistivity coins as well as silver coins, but which will reject copper, Zinc, brass, and lead coins or slugs.

The coin separator of the present invention provides magnetic flux lines adjacent a runway, and provides a deflector and a separator adjacent to, but below the level of, the discharge end of that runway. As a silver coin ice rolls along the runway, the magnetic flux lines will develop eddy currents in that coin which will generate a magnetic field; and that magnetic field will interact with those magnetic flux lines to reduce the speed of that coin sufficiently to enable it to pass between the deflector and separator, and thus pass to an accepted coin chute. As a copper coin or slug rolls along the runway, the magnetic flux lines will develop eddy currents within that coin or slug which will generate a magnetic field; and that magnetic field will interact with those magnetic flux lines to reduce the speed of that coin or slug sufiiciently to cause it to fall short of the separator, and thus pass to a rejected coin chute. As a zinc or brass coin rolls along the runway, the magnetic flux lines will develop eddy currents within that coin or slug which will generate a magnetic field; and that magnetic field will interact with those magnetic flux lines to reduce the speed of that coin or slug to some extent. However, because of the resistivity of zinc or brass, the magnetic field generated by the eddy currents in such a coin or slug will not be great enough to cause a material reduction in the speed of that coin or slug. As a result, such a coin or slug will strike the deflector with sufficient force to cause that coin or slug to rebound back past the separator, and to pass into the rejected coin chute. As a higher resistivity coin, such as a cupronickel coin, rolls along the runway, the magnetic flux lines will develop eddy currents within that coin which will generate a magnetic field; and that magnetic field will interact with those magnetic flux lines to tend to reduce the speed of that coin. However, because of the relatively high resistivity of that coin, the magnetic field generated by the eddy currents in such a coin will not be great enough to cause an appreciable reduction in the speed of that coin. As a result, such a coin will strike the deflector with sufficient force to cause that coin to rebound back to a second deflector; and that coin will then rebound from that second deflector and pass between the first deflector and the separator, and thus to the accepted coin chute. As a lead coin or slug rolls along the runway, the magnetic flux lines will develop eddy currents within that coin or slug which will generate a magnetic field; and that magnetic field will interact with those magnetic flux lines to tend to reduce the speed of that coin or slug. However, because of the relatively high resistivity of lead, the magnetic field generated by the eddy currents in such a coin or slug will not be great enough to cause an appreciable reduction in the speed of that coin or slug. As a result, such a coin or slug will strike the deflector with substantial force. However, lead is relatively soft; and hence while the lead coin or slug will rebound back from the deflector, it will not reach the second deflector. Instead, that lead coin or slug will rebound back past the separator and pass into the rejected coin chute. In this way, silver and some higher resistivity coins will pass to the accepted coin chute, but copper, zinc, brass, and lead coins or slugs will pass to the rejected coin chute. It is, therefore, an object of the present invention to provide a coin separator which accepts silver and some higher resistivity coins, but which rejects lower resistivity and other high resistivity coins or slugs.

A

spring .82 encircles the pivot '74, 'itflhas one end thereof hooked, under the boss 3l, and. it hashthe other endfthereof hooked around the actuator 7'8 for. the wiper. blade 76. That spring biases that wiper b'ladeto the position shown by FIGS. .1 and 2; but itcan yield'to permit rotation of that wiper bladein' the clockwise direction about the pivot 74. a

The numeral 84 denotes a deflector which has a rearwardly-projecting portion of; reduced height that is dis- 7 posed within the slot 36in thefr'ame ZG; That deflector sult, those bosses essentially constitute downward exten;

sions of that.coin-guidingmernber. A shallow, arcuate has a threaded opening therein which accommodates the shank of a screw 86;'and the head of that screw'is wider the frame 20 I than the slot 36 so it can abut the upper and lower edges of that slot and hold that deflector in position within that slot. Loosening of that screw permits shifting of that deflector toward and away from the flange 24. A rebounding surface 85 is provided on the deflector 84; and that rebounding surface coacts with the horizontaliy-directed bottom face of that deflector to subtend an angle of fifty-two degrees. The rebounding surface 85 will be hard and will be strongly resistant to wear caused by the engagement of coins or slugs with that surface. Specifically, the deflector 84 can be made of a hard material or the rebounding surface 85 can be specially hardened.

The numeral 88 denotes an anvil which is secured to the front face of the frame 20 adjacent the openings 44 and 46. That anvil has an inclined face at the top thereof, as emphasized particularly by FIGS. 1 and 2. That anvil can be made of hard material or that inclined face can be hardened. A large, generally rectangular plate 23 abuts the front face of the anvil 88; and nut and bolt combinations 89 secure that plate and that anvil to the frame 26. The plate 98 has an arcuate surface 99 which extends downwardly and forwardly through the opening 46 in the frame 20, as shown particularly by FIG. 5. The plate 98 also has a roughly-rectangular opening 100 therein; and that opening is in register with the recesses 41) and 42 plus a portion of the opening 44 in the frame 20, as shown particularly by FIG. 2. The plate 98 also has a lip 102 which inclines upwardly and rearwardly into engagement with the frame 20, as shown particularly by FIG. 6. A pivot 104 is mounted on the plate 98; and that pivot extends forwardly from the plane of FIG. 2. A gate 166 of bifurcated form is rotatably mounted on that pivot; and coinengaging projections are provided on the ends of the arms of that gate. One of those projections extends into the recess 40 in the front face of the frame 20, while the other of those projections extends into the recess 41 in that front face. That gate is shown and described in Haverstick Patent No. 2,744,603 which was granted May 8, 1956 for Coin Separators. A runway 108 is formed on the front face of the plate 98, and that runway inclines downwardly from upper right to lower left in FIG. 2. That runway extends from a point adjacent the flange 24 to the lower left-hand corner of the plate 98.

The numeral 90 denotes a bracket which is generally L- shaped, as shown particularly by FIG. 7. That bracket has a horizontally-directed slot adjacent the upper end thereof; and a screw 92 extends through that slot and seats in the threaded opening 54 in the frame 20. The foot of the bracket 90 has a pivot 26 secured thereto; and that pivot rotatably supports a separator 94 which has a coin-receiving ear 95. That ear extends forwardly through the opening 48 in the frame 20, and it spans the coin-receiving passageway defined by the front face of the frame 26 and the rear face of the plate 98.

The numeral 110 denotes a large, roughly-rectangular plate which has ears 112 at the right-hand edge thereof; and those ears are disposed adjacent the flange 24. That plate has a small housing 114 thereon, and also has a small housing 116 thereon. Each of those housings encases and supports a permanent magnet; and the magnet within the housing 114- is denoted by the numeral 118. A slot 121 is provided in the plate 110; and that slot inclines downwardly at a shallow angle from upper left to lower right in FIG. 2. An ear 122 extends downwardly from the lower edge of the plate 111); and a set screw 124 is adjustably held within a threaded opening in that ear. That set screw and that ear overlie that portion of the plate 98 which helps define the upper edge of the opening 106 in that plate. The magnetic flux lines developed by the permanent magnet 118 and by the permanent magnet within the housing 116 coact with the disc 72 and with a similar disc adjacent housing 116 to bias the plate 110 toward the front face of the frame 20. The set screw 124 limits the movement of that plate toward that front face; and that set screw is adjusted so the plate 110 is normally substantially parallel to that front face. As a result, the plate 116 and the front face of the frame 20 coact to define part of a coin-receiving passageway.

The numeral 126 denotes a gate which has an elongated, horizontally-directed arm 128 at the upper edge thereof and which has an elongated, horizontally-directed arm 130 at the bottom edge thereof. Those arms extend toward the flange 24; and the right-hand ends of those arms are in register with the bosses 56 and 6t) and with the ears 112 on the plate 110. A generally frusto-triangular coin-guiding member 132 is secured to, and projects upwardly from, the gate 126; and that coin-guiding member coacts with the coin-guiding member 27 on the frame 20 to define a coin entrance for the coin separator. The coin-guiding member 132 is secured to the gate 126 by a screw 134.

A pivot 136 extends vertically-upwardly from the arm 128 of the gate 126, and a roller 138 is rotatably mounted on that pivot. As shown particularly by FIGS. 1 and 2, that roller is immediately adjacent the camming surface 79 on the actuator 78 for the wiper blade 76. An arcuate notch 140 is formed in the left-hand edge of the gate 126; and that notch is immediately below the coin-guiding member 132. Part of that notch is in register with part of the arcuate recess 32 in the front face of the frame 20. An arcuate slot 142 is provided in the gate 126, below and to the right of the notch 140; and a notch 144 of generallyrectangular configuration is contiguous to the slot 142. An arcuate slot 146 is provided in the gate 126, below and to the left of the slot 142; and a straight slot 148 also is provided in that gate. The slot 148 communicates with the arcuate slot 146; and, as indicated by FIGS. 1 and 2, the slot 148 inclines sharply upwardly from lower left to upper right. A further arcuate slot 150 is provided in the gate 126 below the levels of the arcuate slots 142 and 146.

The numeral 152 denotes a pivot which'is secured to and which projects forwardly from the front face of the gate 126. That pivot is adjacent the arcuate notch 140 and the arcuate slot 142, and it is concentric with that notch and that slot. A cradle 154 is rotatably mounted on that pivot; and one of the coin-receiving fingers of that cradle is disposed within the slot 140, while the other of those fingers is disposed within the arcuate slot 142. A feeler wire 156 has a portion thereof rotatably disposed within a groove in a boss, not shown, which is formed on the gate 126 adjacent the lower end of the arcuate slot 142. That boss and a plate, not shown, coact to maintain the feeler wire 156 in assembled relation with the gate 126 while permitting rotation of that feeler wire relative to that gate. A weight 158 is secured to the lower end of the feeler wire 156, and that weight biases the upper end of that feeler wire for movement into the upper portion of the arcuate slot 142. Normally, however, the lower arm of the cradle 154 underlies the upper end of that feeler wire and keeps that upper end out of that slot.

The numeral 160 denotes another pivot which is mounted on the gate 126; and that pivot is adjacent, and concentric with, the arcuate slots 146 and 150. A cradle 162 is rotatably mounted on the pivot 160; and one of the coin-receiving fingers of that cradle extends into the arcuate slot 146, while the other of those fingers extends into the arcuate slot 150. A feeler wire 164 has a portion thereof rotatably disposed within a groove in a boss 167 which is provided on the front face of the gate 126 adjacent the lower end of arcuate slot 150. That boss and a plate 168 coact to maintain the feeler wire 164 in assembled relation with the gate 126 while permitting rotation of that feeler wire relative to that gate. A weight 166 is secured to the lower end of the feeler wire 164, and that weight biases the upper end of that feeler wire for movement into a slot, not shown, in the gate 126. Normally, however, the lower arm of the cradle 162 underlies the upper end of that feeler wire and keeps that upper end out of that slot. A coin-guiding member 170 is rotatably secured to an ear which is provided at the lower left-hand corner of the gate 126; and a weight 172 is secured to that guiding member. A portion of that guiding member extends rearwardly into-an opening, notshown, in the. frame 20. p

A runway 174 is provided on the rear face of the gate 126; and that runway is shown particularly by F IG."2. That runway inclines downwardly ata' shallow angle from upper left to lower right in FIG. 2; and it is in register with the slot 120 in the plate 110. The'runway 174 is provided with a blunt discharge end 176; and that end .co-

acts with a vertical line abutting the upper edge thereof to subteud an angle of ten degrees. 'As indicated particularly by- FIG. '2, the bluntdischarge end 176 inclines upwardly from lowerleft to upper right. A second runway the flange 22. That cover plate'coacts with the runway 108'to guide coins downwardly andto the left in FIG. 2.

The numeral 192 in FIGS. 8-14 signifies, and denotes the location of, an accepted coin chute. The numeral 194 in FIGS. 8-14 signifies, and denotes the location of,'a rejected coin chute. In'the embodiment of coin separator shownin FIG. 1, the rejected coin chute 194 i-s'that portion of the coin passageway, defined by, the plate 98 and-the frame 20, which is disposed, to the left of the coinintercepting car 95 on the "separator 94. The accepted 1 coin chute 192 is that portion of thesaid coin passageway which is intermediate. that car and the: flange 24.

178 is provided on the rear face of the gate 126; and that second runway is below the level of the runway174 and is adjacent the, magnet housing 116. The blunt discharge end 176 of the runway 174 is hard so it can serve as'a second rebounding surface and can strongly resist wear register with the ears 112 on the plate 110, with the righthand ends of the arms 128 and 130 of the gate 126, and with the slots 58 and 62, respectively, in the bosses 56 Inmanyrespects, the coin separator provided by the present invention is similar to standard and usual coin separators. However, in other respects, that coin separatorj is critically different from standard and usualcoin separators. For example, that coin separator has two rebounding surfaces which are struck successively by higher resistivity coins; Thus, the coin separator 'shownin FIG.

1 has the rebounding surface ,85- on-the deflector 84,

which serves as a first rebounding surface, and also has the blunt discharge end 176 Y on the runway 176, which servesas the second-rebounding surface. Also, those rebounding surfaces are disposed so hard-surfaced, higher resistivity coins which successively rebound from them will enter the same accepted coin chute to which silver coins are directed. In addition, the rebounding surface 85 on the deflector 84 is inclined at anangle which causes a 1ine,.perpendicular to that rebounding surfaceand exand 60. An elongated, vertically-directed pin 183 extends through an opening in the'arm'128 of the gate 126,

through an opening in the upper ear 112 of plate 110, throughan opening inthe upper ear of knock-out plate 18%, through a helieally-woundspring 184, through a helically-wound spring 186,. through an opening in the lower ear of knockout plate 180, through an opening in the lower ear 11 2 of plate 119, and throughan opening in the arm 130 of the gate 126. That pin will serve as a pivot;

' and the upper and lower ends thereof will belodged within the slots 58 and62, respectively, in the' bosses 56 and 58. One end of the spring 184 overlies anrear 182 on the knock-out plate 189; and the other end of that spring extends through the opening 64 in'the frame 20. One end of the spring .186 overlies part" of the gate 126; and the other .end of that spring extends through the opening 64 in the frame 20. The springs 184 and 186 hold therp in 183 in assembled relation with theframe 2t}, and also 1 bias the free edge of the g ate 126 and the free edge of the knock-out plate 180 toward the frame 20. The runways 174 and 178 and an abutment on the rear face of a the gate"l26 engage the front face of the frame 20, and

those runways and that abutment normally help keep the rear face-'ofthat gate substantially parallel, to the, front face of that frame. As a'result, that gate and frame define the first part of the coin-receiving passageway.

tending from the point where "acceptable coins strike that surface, to extend above the level of that'point onthe second rebounding surface which will be struck by acceptable coins. Further, that second rebounding surface is inclined at an. anglewhich causes a line, perpendicular topthat second rebounding surface'and extending from the point where acceptable coins strike'thatsurface, to extend above the levelof the separator;

The coin separator shown in FIG. 1 is intended toaccept United States nickels, dimes and quarters. In addition,

that coin separator is intended to, accept coins which are similar to United States quarters; but which are made of cupronickel. Such coins have resistivities which are materially higher thanthe resistivity of a United States quarter. 2 V p 2 'When a United States dimeis introduced into the coin entrancedefined-by the coin-guiding members 27'and 132,

The operation of the coin separator shown in FIG. 1 is, whenever a dime or a dimesized coin or slug is inserted, not significantly different from the operation of other coin separators for dimes.

Whenever a United States nickel is introduced into the coin entrance defined by the coin-guiding members 27 and 132, that nickel will fall downwardly between the coinintercepting fingers of the cradle 154 and be intercepted and held by the coin-intercepting fingers of the cradle 162. That cradle will rotate in the clockwise direction; and, as that cradle rotates, the upper end of the feeler wire 164 will respond to the weight 166 and move toward and engage the surface of the nickel. The nickel will be transferred to, and will roll along, the runway 178; and, as that nickel rolls off of the discharge end of that runway, it will pass through the magnetic flux lines provided by the permanent magnet within the housing 116. Because the resistivity of a nickel is relatively high, the eddy currents developed in the nickel will generate only a relatively small magnetic field; and hence the speed of th nickel will not be reduced materially. As a result, the nickel will rebound from the inclined face of the anvil 88 with sufficient force to pass to and through the space defined by the coin-engaging projections of the gate 106. There after, the nickel will pass downwardly through the coin passageway defined by the plate 98 and the front surface of the frame 29 and pass to the space, intermediate the thickened portion 52 of that frame and the plate 98, which is shown in FIG. 5.

If a nickel-size washer is inserted, the upper end of the feeler wire 164 will intercept and hold that washer. Thereafter, the patron who inserted that slug can effect the return thereof by pressing the scavenging button at the exterior of the coin-operated device in which the coin separator shown in FIG. 1 is mounted. If a nickel-size slug of low resistivity is inserted, the eddy currents developed in that slug will generate a relatively large magnetic field; and hence the speed of that slug will be materially reduced. As a result, that slug will fall short of,

or will gently strike, the anvil 88 and fall downwardly onto the lip 102 of plate 98; and that lip will guide that slug into the space between that plate and the cover plate 190.

I Thereupon, that slug will roll down the runway 1G8 and be returned to the patron who inserted it. If a nickel-size lead slug is inserted, that slug will strike the anvil 88 and will fall downwardly onto the lip 102 of plate 98; and that lip will guide that slug into the space between that plate and the cover plate 190. Thereupon, that slug will roll down the runway 108 and be returned to the patron who inserted it. Whenever a nickel or a nickel-size slug is introduced into the coin separator shown in FIG. 1, the operation of that coin separator is similar to the operation of other coin separators for nickels.

- Whenever a United States quarter is introduced into the coin entrance defined by the coin-guiding members 27 and 132, it will be intercepted and held by the fingers of the cradle 154. That cradle 154 will start rotating from the position shown in FIG. 1 to the position shown in FIG.

2; and, as that cradle rotates, the weight 158 will urge the upper end of the feeler wire 156 inwardly into engagement with the quarter. The quarter will be transferred to, and will roll along, the runway 174; and then it will fall from the discharge end 176 of that runway. The eddy currents developed in the quarter, as it passes through the magnetic flux lines from the magnet 118, will cause the quarter to follow the path indicated by the dashed line 290 in FIG. 8. Specifically, the speed of the quarter will be retarded to such an extent that the quarter will not engage the deflector 84 but will engage, and pass to the right of, the ear 95 on the separator 94. The quarter will rotate the separator 94 from the solid-line to the dottedline position shown by FIG. 8 as it engages and passes to the right of the ear 95. The quarter will then pass to the accepted coin chute indicated by the numeral 192 in FIG 8.

If a quarter-size washer is inserted, the upper end of the feeler wire 156 will intercept and hold that washer. Thereafter, the patron who inserted that slug can elfect the return thereof by pressing the scavenging button at theexterior of the coin-operated device in which the coin separator, shown in FIG. 1 is mounted.

If a quarter-size coin of cupronickel is inserted, that coin will have a hard surface and will also have a resistivity higher than the resistivity of coin silver. Because of that relatively high resistivity, the eddy currents developed within that coin will be relatively small; and the magnetic field generated by those eddy currents also will be small. Consequently, the interaction between that magnetic field and the magnetic flux lines from the magnet 118 will not appreciably retard the speed of the coin. As a result, the coin will squarely engage the rebounding surface on the deflector 84 and will rebound back toward the blunt discharge end 176 of the runway 174. That coin will squarely strike that blunt discharge end; and it will strike that blunt discharge end with sufficient force to rebound from that blunt discharge end and engage, and pass to the right of, the ear on the separator 94. That coin will cause the separator 94 to rotate from the solid-line to the dotted-line position shown in FIG. 9, as it engages and passes to the right of the ear 95. This means that the coin will follow the path denoted by the dashed line 202 in FIG. 9 and will pass to the accepted coin chute 192. Significantly, the cupronickel coin as well as a quarter pass between the deflector 84 and the separator 94 and enter the accepted coin chute.

As indicated by the dashed line 202 in FIG. 9, the cupronickel coin squarely engages the rebounding surface 85 on the deflector 84 at a point above the lower edge of that rebounding surface. Thereafter, that coin squarely engages the blunt discharge end 176 of the runway 174 at a point spaced above the bottom edge of that discharge end. Finally, that coin rebounds through the space between the deflector 84 and the separator 94.

If a quarter-size copper slug was inserted and reached the runway 174, the eddy currents generated within that slug would be greater than the eddy currents generated within a quarter. Those eddy currents would develop a magnetic field which would interact with the magnetic lines of flux from the magnet 118 to retard the speed of the slug so materially that the slug would not reach the deflector 84; and, instead, would fall downwardly and pass to the left of the ear 95 on the separator 94. Consequently, that slug would be directed toward the rejected coin chute 194 by the separator 94. The path which would be followed by a copper slug passes well to the left of the deflector 84, and then engages and passes to the left of the ear 95 on the separator 94.

If a quarter-size zinc or brass slug was inserted, the eddy currents developed within that slug would be less than those generated within a quarter but would be greater than those generated within the cupronickel coin of FIG. 9. Those eddy currents would generate a magnetic field which would interact with the magnetic flux lines from the magnet 118 to retard the slug sufficiently to keep it from squarely engaging the rebounding surface 35 on the deflector 84. As a result, that slug would strike the lower left-hand corner of that deflector a glancing blow and then fall back toward and past the ear 95 on the separator 94. That slug would rotate the separator 94 from the solid-line position to the dotted-line position in FIG. 11 and then pass to the rejected coin chute 194. The path which would be followed by a zinc or brass slug is denoted by the dashed line 206 in FIG. 11.

If a quarter-size lead slug was inserted, the eddy currents developed within that slug would be materially smaller than those generated within a quarter; and hence the speed of that slug would not be materially reduced. As a result, that slug would squarely engage the rebounding surface 85 of the deflector 84in much the same manner in which the cupronickel coin of FIG. 9 squarely pass to the rejected coin chute194. The path which 12. the relative positions of the magnet118 and of the runway 174 will not materially afiect'the operation of the would be followed by a lead slug is shown by the dashed line 263- in FIG. l2.

After the quarter of FIG; 8 or the cupronickel coin of FIG.9 has passed between the deflector 84 and the separator 94, it will move downwardly through the coin passageway defined bythe plate 98' and the front face of the frame 20 until it 'engages the arcuate'surface 99. That surface will guide that quarter or coin through the opening 46 and into the space between the wall 188 and the partition187; and, thereupon, that quarter or coin" will pass to the cash box of the coin-actuated device in e which the'coin separator shown in FIG; l is mounted.

f the deflector 34' ofFIGS. l-13.

Copper, zinc, br'ass,and,lead slugs will pass to the'left V of the car 95 on the separator M, and will fall downwardly and engage the lip 162 adjacent the bottom of the opening 100' in the plate 98." That lip will guide.

those coins through that opening and'in'to the space he tween the wall 98 and the cover plate 1%. Those coins will then fall onto the runway 108, and will roll'downwardly toward the flange 22 until they are free'to fall into a chute, not shown, which will conduct them to a coin return receptacle at theexterior of thecoin-actuated device .in whichthe coin" separator shown in FIG. 1 is.

mounted. a

In the coin separator of FIG. 13, themagnet'1 18 has been shifted upwardly and tothe' left from' the position I which it occupied in FIG. 12., Also, the deflector s4 and the separator 94have been shifted about one-sixteenth of an inch to the left- In all other respects, the coin separator of FIG. 13 can be identical to the coin separator shown in FIG. '1'.

-When a quarter-size hard-surfaced. coin of relatively high resistivity, as for 'eiiample a-cupronickel. coin, is inserted'in the coin separator of FIG. 13, that-coin'will rollalong the runway l74without appreciable retardation and will squarely engage and rebound-back frornthe reboundw ing surface of the deflector 84'. That coin will then because it saves space and also minimizes the :number of However, as shown by parts in the coin separator. FIG. '14, the second rebounding surface can be provided on a second deflector; Specifically, the coin separator of FIG. 14 has a second deflector 220 with a second rebounding surface 222' thereon; and that second deflectorand that second rebounding surface'are entirely'independent of the runway 274. It will be notedthat the rebounding surface 2% on the deflector 284 of FIG. 14 inclines upwardly at a steeper angle than does the rebounding surface 85 on 7 However, the rebounding surface 255, is disposed iso a line which is perpendicular to that surface and which passes through the point Where acceptable coins engagethat'surface will pass above the level of that. point on the rebounding surface 222 which'is subsequently engaged'by those coins. Further, itz'will be noted that the rebounding surface 222 is disposed so a linewhich is perpendicular tothat surface and which passes through the point where-acceptable-coins engage that surface will pass above the level of the ear 295 on the separator 24 of1 1G514.-

As in the casefof the coins shown in FIGS. 9 and 13, the coin shown in FIG. 1'4 moves :in one direction above and beyond the dividing line between the-accepted and rejected coin chutes to'sq'uarely engageand rebound from a first rebounding surface, movesback in squarelyengage and'rebound from the blunt dischargeend 1760f the runway 174, and will engage and pass to' the right of the ear on thesepar'ator g t-thereby;

When a quarter isinserted in identical to the path'indicatedby the dashed line Ztiilin the coin separator of. FIG. 13, that quarter will follow a path which is almost the oppositedirection above and beyond that dividingline to squarely engage and reboundfr-om a second rebounding surface and then again moves in the said one direction above and beyond that dividing line to pass to the accepted coin chute.

In the coin separators of FIGS. 1-14, a silver coin, such as a quarter, and a quarter-size, hard-surfaced coin of higher resistivity, such as a cupronickel coin, have been accepted while cop-per, zinc, brass, and lead slugs have been rejected. However, the coin separators contemplated by the present invention are not limited to the acceptance of coins of any given size, and are not limited to the acceptance of silver coins and of coins of higher resistivity. Instead, the coin separators contemplated by the present invention can be used to accept coins of a given resistivity plus hard-surfaced coins of higher resistivity while rejecting slugs of intermediate and lesser resistivities and also rejecting relatively soft slugs of higher resistivity. In fact, the coin separators contemplated by the present invention can be used to reject quarters while accepting cupronickel coins; as by weakening the magnet 1 1-8 sufficiently to permit quarters 'to strike the rebounding surface 85 on the deflector 84 and then fall back to the left of the ear 95 on the separator 94 and pass to the rejected coin chute 194.
