The lower part I the de ice cQntaining the vertical coin channels "is adapted ito eject coins havingelectrical conductivity or resilience differing from hat of a genuine coin. This part will -beref erred to as the lower unit.

I As sh wn inF-igs. 1 and 3, a 'throat piece a base plate 21 a spa oer block 314, and a cap plate '9, thelatter being omitted in Fig. 1 for clarity,

are attached by suitable rivets or bolts to a front panel I. A rim 52, Figs. 3 and 4, surrounding the front oithe coin entrance may be provided to improve the appearance. The panel l is cut out atapproxirnately the inner edges of the run to io idi n opening. re ive h hroat e 2 which ,is correspondingly recessed to fit ,this opening. The upper part of the base plate 21 slopes slightly to .the rear relatively to; the 'vertical front panel I then is curved to the rem i thee t on be n n -11 st above h low r edge ..o .Q.P 'Q@PPiQB .2, and gine. Jus new lowi" edge of thrd a'it' fii 2'. From this point downward the base plate 27 is at a greater slope relative to front panel I than is the upper part of base plate 2?.

A cylindrical bore 3 is provided in throat piece 2 01' such diameter as to just pass a genuine dime and prevent the insertion of a disc larger in diameter thana dime. A corresponding cylindrical bore 3' is also provided in throat piece 2 of such diameter as to just pass a nickel. An opening is provided in base plate 2'! the top of which opening is semi-cylindrical in shape and is in alignment with the upper part of bore 3. Approximately tangent to said semi-cylindrical opening the plate 27 is cut away to form walls 5 and 6 that slope slightly to the left relatively to a vertical plane through the axis of bore 3.

The indication of direction by the terms right and left are to be considered throughout this description as right hand or left hand as viewed from the front of the apparatus, Fig. 4, regardless of the views in which the parts referred to may appear.

Below the opening between Walls 5 and 6 the plate 21 is further cut away in the more inclined portion so that between the edges of parts i and II on release slide is and an edge iii of the said opening in plate 21 an opening I8 is formed through which under size discs and irregularly shaped pieces may be ejected.

A thickness gauge plate til, Fig. 5, is supported in the space inside the inverted U-shaped spacer block 34 by means of ears 64 which fit loosely in the notches in the block 34. The cap plate 9 covers the opening in the spacer block 34 and lugs 63 on the top of plate 60, loosely engaging the cap plate 9, serve to limit the movement of the top of the plate 60 so that it is in efiect pivoted at its top on the ears 64. A spring 6?, attached by means of ears 66 to plate 33, by engagement with cap plate 9, serves to hold plate BB in normal position against the base plate 21. A plate 6 I, attached to thickness gauge plate 33 and adapted to project slightly into the opening between walls 5 and 6 in the base plate 21, is made of such thickness that a dime of maximum thickness will just pass through the passageway formed by walls 5 and 5, plate GI and a bridge surface 8, Fig. 1.

A locking slide 5'! is provided adapted to have a slight endwise movement in slots 36 and 3'! in the spacer block 34 and is retained in place by the cap plate 9. A locking edge 58', shown in Fig. 1, is provided on slide 51 which is adapted to engage a lug E2 on thickness gauge plate 61! to prevent the gauge pate from being pushed back thus preventing the insertion of a disc thicker than a genuine dime. For greater rigidity a locking edge 58, identical in structure and function to locking edge 58, is provided on slide 51 for engagement with lug 32 on plate 60, Fig. 5. The locking edge 58 is on the portion of bar 51 that is cut away in Fig. 1 and therefore does not appear in the drawing.

A coin release slide I5, Fig. 8, having its upper part curved and adapted to fit on the under side of the base plate 21 in the position shown in Figs. 1 and 4, is slideably attached to the base plate 2! so as to permit a slight endwise movement in a direction parallel to the s'ot 39. It is guided at one end by a pin 48 on slide I8 engaging with a slot 4! in plate 27 and guided at the other end by a pin 14 on plate 21 engaging in a slot 33 in plate IE. The throat piece 2 is cut away to accommodate the upper part of slide 16 in the position shown in Fig. 1 and'to permit the end= 4 wise motion of slide I6. The slide I8 is held in position against the under side of plate 21 by means of springs 43 and 44 attached to plate 21.

A narrow curved shelf I6 is provided project ing below the lower side of base plate 21. The uppermost surface of shelf 13 is in alignment with bridge 8 and its lower surface merges into an inclined surface I4 extending along the edge II! of the hole I8.

The wall 6, which is perpendicular to the surface of plate 21, extends downward and merges into an edge 11 that is at a gradually decreasing angle relative to the surface of plate 21. The edge 11 extends along surfaces I and II on the coin release slide I6 forming a V-groove I3 which has a gradually decreasing angle relative to the surfaces 1 and I I. The V-groove I3 curves to the rear away from panel I at its upper end and also curves to the right.

An iron insert 38 extending through the plate 21 from 'top to bottom is cut away at its upper end to form a continuation of the edge I1 and thus forming a continuation of the V-groove I3 to a point where it runs out or ends at the edge of the iron insert 38. The distance between the lower end of the V-groove I3 and the diametrically opposite point of the wall I0 is such that a genuine coin of minimum thickness, fully seated in the V-groove, will very slightly overlap the surface I4 above Wall III.

A permanent magnet I2 mounted on a bar I5 is placed so that one of its poles is in contact with the upper end of the iron insert 38 thus creating a magnetic field at the lowermost end of the V-groove I3. One end of the bar I5 is adapted to slide in a guide bracket 9| attached to plate 21 and the other end is supported on pin 40' extending through the foot of the bracket I5.

An L-shaped light steel spring 24 is provided attached at its upper end to a spring support 23 pivoted on a screw I8 and having an adjustment slot I9 with a suitable retaining screw at its lowermost end. The arm on the spring 24 extends through the discharge opening I8 across the edge of the coin path and a notch 54 is provided in the edge Ill in plate 21 to receive the arm of spring 24 when it is deflected by a coin.

The front of the throat piece 2, Fig. 4, that is accessible through the opening in the front panel I, contains the entrance to the cylindrical bores 3 and 3' for receiving dimes and nickels respectively. The front of the throat piece is dished out alon a surface approximately parallel with the plate 21 down to the lower edges of the coin entrances'from which point it slopes sharply to ward the front. Below the dime coin entrance and to the right of it a sloping hole is provided through the throat piece 2 adapted to slideably support a coin release plunger 68 that extends out the front partially in the dished out portion of the throat piece 2. The inner and lowermost end of the plunger 68 is attached by a pin or rivet to an L-shaped arm 10' on a coin release operating slide 69, shown detached in Fig. 6. The slide 69 is slideably retained in achannel formed by plate 21, guid'eblocks 82- and 83 and an H-shaped cover plate. suitably fastened to gether by rivets or screws. A hole H8 is provided in the curved portion of the plate 21 to receive the upper end of the slide 69 and the arm 70 thereon.

A lug I3 on the slide 69 extends through a. slot 84 in plate 21. A coin release operating link I85 is attached at one end by a loose rivet or the like '60 the 111g 3 and-at'itS-Othr'nd to a-"co'in" awn-s rerease'eeeran ng lever we pivoted at 1.01, in the lower as explained --later.

At thebe'ginnin-g of it retumrneve merit the extension on arm 10 will pas out of engagement with the end or arm '65'of1 the plate enabling the spring Bl to return the plate to normal position against the plate 21 if there are no obstructions in the coin channel to prevent this. If there should be an obstruction in the coin channel to prevent the restoral of plate 60 the edge 58' on bar 51, whichat this point would normally be'mbved to -the-- right by the sliding action of pin 59 in slot 12; will engage lug 52' on plate 60 preventing this and the'slope in the slot 12 will prevent the sprin 8-8 rrom restoring the slide 69 to normal position, The coin release slide I6 would therefore not be restored to bring the bottom I of the V-groove I3 into 0p erative position and any coins or j'objects inserted would not besuppQ d by thesuriaee 1 and would be discharged through the opening l8. when the obstruction is removed, permitting the plate 60 to restore by the action of spring Bl, the lug 62' will pass out of engagement with the edge 58' on the locking bar 5'! and the locking 'bar will be free to move toward :the right by the ac'ti'di-lof pin 40 v normal posit-ion ready for the reoperatio'n of the device.

gravity with the exception of its movement after the rebound from the anvil in the lower unit The path of "a genuine coin from the passageway between bridge '8 and plate 61 and continuing downward with its edges supported by the V- groove. I3 and the surface I4 is indicated onthe drawings ,by the reference numeral 4 and it is to be understood that this reference numeral does not refe'r to any particular element of the device. The upper part of this coin path 4 is the form or an elbow or a coin. channel bent edgewi'se. This elbow also curves toward the rear away from the front panel I.

A genuine dime will pass freely through the coin-entrance or bore '3 to a point parallel to the plate 6| thence through the passageway formed by Wall 5, bridge 8, wall 5 and plate -6I. This passageway slopes slightly to the rear so that the coin has a tendency to slide against the bridge point 8 and owing to the'slope of wall '5 it will slide or roll on its edge along wall 5 to the end of wall 5. A portion 22 of the bridge 8 is cut away at a slight slope forming an edge that is an extension of the edge of the surface I. The perpendic'ula-r distance, relative to wall 5, from the lower end of wall 5 to the edge of surface 7 is somewhat less than the diameter of a dime so that at this point 'a dime will be supported on one edge by the surface -I and on its opposite edge by the shelf 15. Since surfaces 1 and 16 curve toward the rear at this point the dime will be deflected toward action oi spring BG on slide B5, gnsequently the aide mane the-magnet bar w re gr ster the rear. The coin in passing down the channel with its edge in contact with wall 5 will gain some momentum'and be deflected edgewise toward the left due to the slope of wall 5. This momentum is sufiicint to prevent the coin from slipping oil the edge of surface 1 after it passes out of con tact with wall5. As the'coin continues downward its one edge will be supported by surface l4 and its opposite edge will enter and be supported by V-g'roove I3 which is curved in such direction as to deflect the coin edgewise toward the right.

The edgewise change in the direction of the coin takes advantage of the momentum of the coin to cause it to become fully seated in the V'- g-roove. The angle of the Vg-groove gradually decreases as it extends downward, as has been explained, to further aid in 'fully seating the coin in the-V-groove. The surface I6 and the surface I4 into which it merges are formed with a gradually increasing slope relative to the plate 21 down to a point diametrically opposite the lower end of the V-groove, this slope being in such direction that it also tends to crowd the coins into the -V-groove.

The momentum of the dime as it passes out of the v' -groove at the edge of the iron insert 38 carries it along a trajectory, supported on its "opposite edges by surfaces H and I4, toward the spring 24. The edge of the coin strikes the spring 24 which is of such strength and adjusted in such position that it will be deflected by a genuine dime, of any weight in normal circulation, at sufilcient amount to mOVe the Spring 24 into the notch 54 far enough to; permit the edge of the dime to continue to side on -surface J4 causing the dime to be guided'theteby over the seeing surface I9 through the space between blocks 88' and 82 and over a portion of the tilted surface I! into a vertical channel 25 in the lower unit.

A disc larger in diameter than a genuine dime will not pass through the bore 3 and an object of greater thickness than a dime will not pass through the passageway between bridge 8 and the spacer plate BI. Likewise an object having one dimension greater than the diameter of a dime will not pass through the bore 3 in a position parallel to the spacer plate GI and therefore it would not pass into the coin channel. An object having one dimension only slightly greater than a dime might be inserted at an angle to the plate Gland become wedged between the plate 6| and the bridge 8. In this case the operation of the coin release plunger 68 will cause plate 5| to be pushed back and the under surface I of the V-groove 'I3' to be pushed aside thus allowing such an object to pass and be ejected through the opening I8. Likewise a disc or object thicker than a dime that might become lodged between the bridge 8 and the plate 6| may be released to pass out the opening I8. Thus objects having any dimension greater than the corresponding dimension of a dime are prevented from passing down the coin path or coin channel 4.

A disc appreciably smaller in diameter than a dime will roll down along wall 5 through the channel between bridge 8 and spacer SI but the edge of the coin diametrically opposite the edge that is in contact with wall 5 will not extend far enough to be supported by the surface I. The disc will therefore slip ofi the edge of surface I and pass through the discharge opening I8.

At the lower end of wall 5 the plate 2'! is cut away to form a surface that merges with the sur-' face of the shelf 16, and the edge of surface 1 extends downward a gradually increasing distance from the end of wall 5. This construction is provided so that a coin having a. flattened side or one slightly out of round and of such a dimension that it will just barely reach the edge of surface I will not bind between the edge of surface I and the lower end of wall 5. When such a coin slips off the edge of surface I the increasing distance between this edge and the end of wall 5 allows the coin to pass on down the coin path or channel 4 with its right hand edge free to pass over shelf I5 and surface I4 thus leaving its left hand edge slip completely off the edge of surface I at a point where this edge curves toward the rear and toward the right allowing the coin to pass out the opening I8. In a similar manner small irregularly shaped objects pass out through the opening IS.

A disc of a. diameter only slightly less than that of a dime is carried by its momentum into the V-groove I3 and proceeds down the coin path 4 in the same manner as a dime, passing out the lower end of the V-groove toward the spring 24 as has been explained. Such a disc being fully seated in the V-groove, as has been explained, will slip off the surface I4 just above the spring 24 and its right hand edge will slip down over the edge I8 causing the coin to be ejected through the opening I8. Likewise a disc that is thinner than a dime will be seated deeper in the V-groove than a dime and will slip off the surface I4 and down over the edge I8 just above the spring 24 and be ejected through opening I8. 2

A disc that is of the same dimensions as a dime but of lighter weight material will travel in the same path as a dime to the point where it strikes the spring --24 but will not have enough momentum to deflect the spring 24 asuflicientamount to permit its edge to be supported by the surface I4. It will therefore slip off the surface withits left hand edge supported by surface II; its right hand edge will continue to drop slightly along the edge I8 so that its lowermost edge willstrike the lowermost edge of the opening I8 caus ing the coin to drop or slide out the lower end. of the opening I8 the left hand edge of the-coinpassing through the notch I5 in the slide I6.

A genuine dime that is worn thin will have less weight than anew dime and in order to prevent such a coin from being ejected like a coin of light weight material as explained above the strength of spring24 and the amount of its deflection after being struck by a coin is so chosen a-s'to compensate for the variation in thickness of genuine dimes. A thin dime is seated deeper in the V-groove than a new dime and therefore its trajectory is such that its edge will not strike spring 24- as quickly as a new dime and the strength and deflection of spring 24 under this condition is such as to permit the edge of the thin dime to ride on surface I4 and be guided over surface I8 into the channel 26 in the lower unit- A disc of light weight material having the thickness of a new dime will be seated in the V-groove as deep as a new dime and its trajectory will be such as to strike the spring 24 sooner than a. thin dime and the deflecting force of the spring is such as to cause such a coin to be ejected in the manner explained. H

A disc of iron or other magnetic material that has passed down the coin path 4 will, as it passes the end of the V-groove, be attracted by the magnetized insert 38 and roll along the edge of the insert 38 which slopes slightly toward the left. ,This will cause the right hand edge of the coin to slip off the edge of surface I4 and the coin will tend to drop through the opening I8. The magnet I2 is in contact with the insert near the top of insert 38 therefore the strength of the magnetic field decreases toward the lower end of insert 38 and the edge of plate 21 projects very slightly at a point I21 beyond the lower edge of insert 38. The magnetic attraction be tween the coin and the insert 38 will therefore decrease as the coin proceeds downward and, when the edge of the coin strikes the projection I27, in the non-magnetic plate 21 its momentum will release it from the insert 38 allowing the coin to pass out the opening I8.

When a coin that is attracted by the insert 38 slips off the edge of surface I4 its right hand edge tends to drop along wall I8 and its left hand edge may be tipped up and be pulled by magnetic attraction over the top of the insert 38. The projection I2! is formed so as to engage a coin that might reach this position to prevent it from being drawn So far to the left as to cause it to be deflected over the surface I9 into the channel 26. g

Should any object become lodged in the V- groove I 3 the depression of thecoin release plunger 6'8 will cause the surface I and II, forming the bottom of the V-groove, to be pushed aside allowing the object to drop out by gravity. Should any magnetic object become attached to the iron insert 38 the operation of the plunger 68 will move themagnet I2 away from the insert 38 and will also move the surface II to theleft. The magnetism-will thus be removed from-theinsert asses 8 ria to, r ease he dbi dt. from he. nsert 38 and the return movement of surface II will assistin the release of th object, allowing it to pass out thro iel il h openin In the upper unit described above coins or ob j e'cts o im rop r size, coins df' ilzht weigh aeria and; m s ma netic coins are. k p 0.1 1 or ej cited and only nonmagnetic, coins 'or very i coins of the'si'z'e and.

A U-shaped rack I I3 is adapted to slide on the upper edge of plate 3| held in place by pins I I4 extending through slots H5 in plate 3I. The upper end of the lever I06 is loosely attached by a pin to the rack H3 so that when the coin release lunger 68 is depressed the lever I06 is rocked on its pivot post I01, as has been explained,

the action of the rack II3 to sweep cross the space in the nickel channel adjacent to the poles of the magnet I09. A sweep piece I|6 shown dotted in Fig. 2, similar in structure and performance to the sweep piece I I6 which is shown more clearly in Fig. 2, is provided in connection with the dime channel.

A coin that passes from the upper unit into coin channel 23 will be of the size of a genuine dime and generally of non magnetic material. However, a coin of material that is only slightly magnetic may not be attracted with sufiicient force to the field of magnet I2 to be ejected in the upper unit and it would pass to the lower unit. When such a coin is deflected against the plate 29 at the point where the magnetic field of magnet I09 is established it will be attracted and held by this magnet. The operation of the coin release plunger 68 causes the arm of sweep piece H6 to be moved over the space adjacent to the poles of magnet I09 sliding the coin to the left to a point where the lower fioor of channel 10 ,causin the rack H3 to be moved toward the 26 is cut away and releasing the coin from the magnet I09 allowing the coin to pass over the sloping surface II out through a discharge opening 20 between the edge of surface I! and the plate 29.

If, when onemagnetic coin is being held by the magnet I09, a dime is inserted in the device, it will strike the side of the stuck coin. The tilted surface I1 is 'so positioned relative to the stuck coin that. the good coin will be deflected to I the left between face of the stuck coin and the tilted surface I! and be ejected through the discharge opening 20. The purpose of this arrange-- ment is to prevent any slightly magnet coin from passing down the coin channels 25 and 46 to the strong magnets 41 and sticking in the channel at this point to completely clog up the selector.

A coin passing down the channel 26 will be carried by its momentum over the sloping surface 45 so that its edge will strike the abutment I23. Since the distance between the abutment I23 and the wall directly opposite it is approximately equal to the diameter of a dime the right and left movement of the coin is essentially stopped and the coin will be constrained to slide over sloping surface 45 into the coin runway 46 where it will be brought practically to rest momentarily because the only momentum it has when it strikes the bottom of runway 46 is that gained in falling from the surface 45 down to the bottom of the runway. The coin runway 45 slopes slightly at this point allowing the coin to roll by gravity down the coin runway 46 through the field of magnets 47. In passing through this magnetic field the coins are retarded more or less in proportion to the electrical conductivity of the metal of which they are made and travel in different trajectories after leaving the supporting edge of the bar 94 in the bottom of the runway. A genuine dime will have such trajectory as to pass 12 clear of the .abutments 5| and 53. and strike the anvil 48 squarely and rebound over the barrier 49 into the channel 50 for genuine coins.

A coin having higher conductivity than a dime will be retarded more than a dime and its edge will strike the abutment 5 I. It may be deflected by the abutment 5|,sufficiently to cause its edge to strike also the abutment 53. In this case it would be deflected by the abutment 53 in such manner that it would not strike the anvil 48 squarely and with sufficient force to cause it to rebound over the barrier 49. The coin would therefore pass out the discharge opening 42. A coin may strike abutment 5| and be deflected just enough to strike the anvil 48 missing the abutment 53. The contact of the coin with the abutment 5| slightly changes its direction, slightly changes its momentumand has a slight tendency to cause it to rotate. The coin being subjected to all of these effects combined does not strike the anvil with the clean blow necessary to cause it to rebound over the barrier 49. Such a coin sometimes has the appearance of being trapped bouncing around from one of the points 48, 46 and 53 to the other and finally passing out the discharge opening 42.

A coin having a lower conductivity than a dime will have such a trajectory that its edge will strike the abutment 53. In this case it will either be deflected through the discharge opening 42 or strike the anvil with insufficient momentum to cause it to rebound over the barrier 49 and it will therefore pass out the discharge opening 42.

In the upper unit the nickel coin selector is identical in structure and functions to the dime selector the nickels passing to the lower unit through the space between the blocks and 8|. In the lower unit the details of the construction of the channel 26' for receiving a nickel from the upper unit are somewhat different from the dime channel construction and a different principle is employed for bringing a coin to rest momentarily before startin down the coin runway 46. These differences are used to facilitate the construction of the device in a combined unit for both nickels and dimes.

The vertical extension 86 on the base plate 21 is attached to the center plate 3|, Fig. 1. The spacer plate 32, slightly thicker than a nickel, is adjacent to the center plate 3| and within it are formed the nickel coin channels 23' and 46', Fig. 2. Plate 33 forms the rear wall of these coin channels. A hole I25 is provided in the plate 3| through wh ch coins from the upper unit pass into the coin channel 26. A tilted surface I1 is provided having the same function as the tilted surface II but in this case it is best formed by bending a triangular piece of plate 3| along the line I2I to meet plate 2! along the line I20. A dscharge opening 20' is provided at the edge of the tilted surface II the extension 86 being cut away at this point sufficiently to permit the ejection of coins passing over surface IT. The spacer plate 32, forming the floor of channel 26', is also cut away at the upper end of channel 26 to permit passage of any coins ejected over surface II through the discharge opening 20 as explained in the operation of the dime selector.

A light spring III is attached to plate 33 and extends slantingly into the coin channel through opening H2. A nickel passing down the channel 26 is carried by its momentum against an abutment I26 formed in the coin channel then passes downward pushing aside the spring III the and falling-upon the: floor of? upper en qt spring-: tFFwhici Yaftenthe pas age of the coin aturns-to no a1 position to engage the upper edge of tHe co1n'.

If the bar 94 is adjusted toward the left the trajectory of the coin would be brought nearer the abutment 53 and the coin would also pass through a smaller number of lines of magnetic force further tending to bring the trajectory nearer the abutment 53. This adjustment may be used in originally setting the device for proper separation of genuine coins from spurious coins and would also serve for readjusting the device should the strength of the magnets 4! become reduced.

Walls 92 and 93 are fitted between the panel I and the adjacent selector plates and suitably attached to the selector plates forming a channel through which coins ejected at the upper discharge openings I 8, I8, 20 and 20' are directed to the bottom of the device adjacent to the lower discharge openings 42 and 42'.

The various devices for testing the size of the coins may be readily manufactured so that no adjustment of these elements is required, therefore the only adjustments required in the device are the relatively simple adjustments of the bars ,94 and 94 and the adjustments of the springs 24 and 24' by meansrof the spring supports 23 and 23'.

The device described is a multi-coin unit for nickels and dimes. It is to be understood that the device may be employed for other coins by very minor changes in construction and that the same principles may be employed to construct a multi-coin unit for more than two coins.
