11 Claims.

This invention relates to a detector designed primarily for use in connection with coin controlled vending machines, but it is to be understood that a detector, in accordance with this invention, is for use in connection with any machine or mechanism for which it may be found applicable, and the invention has for its object to provide, in a. manner as hereinafter set forth, for automatically detecting blanks, annuli, slugs,

discs, or counterfeit coins inserted therein to prevent their travel to a point of destination for the reception of good coins, such destination being a coin controlled mechanism.

A further object of the invention is to provide,

in a manner as hereinafter set forth, a detector for preventing the operation of a coin controlled mechanism surreptitiously by the use of slugs, discs, annuli, counterfeitcoins or other substitutions which do not have certain configurations of a proper coin of predetermined denomination.

Further objects of the invention are to provide, in a manner as hereinafter set forth, a coin detector which is comparatively simple in its construction .and arrangement, strong, durable, readily assembled, automatic in its detecting function, thoroughly efficient in use, and comparatively inexpensive to manufacture.

With the foregoing and other objects which may hereinafter appear, the invention consists of the novel construction, combination, and arrangement of parts as will be more specifically described and as are illustrated in the accompanying drawings wherein is shown an embodiment of the invention, but it is to be understood that changes, variations, and modifications maybe resorted to which fall within the scope of the invention as claimed.

Figure 8 is a sectional detail of the coin slide and its supporting and guide means,

Figure 9 is a detail looking towards the top or 55 ment of the outer shaft structure, and

the bottom of the head part and clutching ele- Figure 10 is a view of the parts in Figure 9 from each side thereof.

There is illustrated an upstanding support I upon which the detector is suspended. The support I may be the front of a coin controlled ma- 5 chine in which the detector is installed. The support I is formed with a. horizontal coin slot 2 of the desired width and length. The support I centrally with respect to the top and

bottom walls

3, 3 respectively of the coin slot 2 is provided with oppositely disposed

cutouts

4, 4 respectively (Figures 1 and 8). Secured to the front face of support I is an angle-shaped combined retainer support, and guide device 5 (Figures 1, 2 and 8) for an angle-shaped coin slide 6 formed at its inner end with a vertical stop 1, intermediate its end with a coin receiving opening 8, and at its outer end with a thumb piece 9. The device 5 includes an angle-shaped upper section formed with a vertical leg I0 and an outwardly directed horizontal leg II. The device 5 includes a lower section formed of a vertical leg l2 and a horizontal leg l3 extending outwardly from the upper end of leg l2. The latter is of greater length than leg Ill. The legs lil, l2 constitute abutments for the stop! to prevent the separation of slide '6 from support I. The leg I3 is of greater length than leg H and formed at its sides with inwardly extending oppositely disposed flanges l3 overhanging and spaced from the upper face of leg l2 to form a pair of parallel spaced guide grooves It (only one shown) for the slide 6. The flanges I3 at their inner ends abut the ends of leg Ill and constitute retainers for maintaining the slide 6 uponleg I3. The latter is formed with an opening it of less diameter than opening 8. The legs l0, I2 are secured against the front of support I by the holdfast means IT. The purpose of the slide 6 is to conduct a good coin or a slug, annulus, discv or other spurious substitutions for 40 a good coin to discharge into a combined chute and detection structure I8 which leads to a combined slug detecting, good coin directing, and coin and slug discharging mechanism to be referred to.

The structure l8 includes upper section and 5 lower section i9, 20, respectively. The section H] has its upper end disposed below the slide 6, when the latter is shifted inwardly with a good coin or spurious substitution for the latter to receive the coin or substitution from the slide. The section I9 extends downwardly at an inclination from its upper end to the upper end of section 20. The latter is vertically disposed.

The section l9 includes a head piece 2| formed with acircular opening 2 I an upstanding flange 22 at its rear side and 2. depending apertured flange 23 at its front side. The flange 23 is anchored to the inner face of support I. The section l9 includes a pair of spaced

parallel side rails

24, 25 which merge at their upper ends into the head piece 2|. The lower ends of the

rails

24, 25 are inturned and merge into the front and rear walls of the upper end of section 20. The bottom edges of the

rails

24, 25 have aligning rectangular notches 26, only one of which is shown (Figurel). Arranged between the

rails

24, 25 is a detector element 21 in the form of a weighing scale consisting of a flanged slotted pan 28 having its upper r end pivoted on a shaft 29 .mountedin the lower 32 coacting with the notches 26 for limiting or arresting the upward movement of the lower end of pan 28 provided bythe counterweight 3|. The purpose of the element 21 is to cause the discharge fromthe section |9 of the chute of a coin or substitution therefor when such coin or substitute is heavier than the weight of that of a good coin. The element 21 is so constructed that the weight of a good coin will not overcome the effect of the counterweight 3| on pan 28 to lower the latter. When the weight of the substitution of a good coin delivered into the section IQ of the chute overcomes the counterweight, the pan 28 is rocked downwardly on its pivot and such substitution is dumped from pan 28 to prevent its being discharged from the lower end of section IS.

The section 26 includes an upper and a

lower stretch

33, 34 respectively. The stretch 33 is disposed at right angles to and merges into the upper end of the lower stretch 34. The stretch 33 is directed towards the

rails

24, 25. The stretch 33 is formed of a pair of

legs

35, 36. The leg 35 extends from and is disposed upwardly at an inclination with respect to leg 36, The leg 35 consists of a pair of

sides

31, 38 and a downwardly sloping bottom 39. The leg 36 consists of a vertical rear wall 46, a front wall 4| which inclines away from and is disposed upwardly relative to wall 46, a side wall 42, and a tapered slightly inclined side wall 43. The leg 36 in top plan is of hopper-like contour. The walls 4|], 4| merge into the

rails

31, 38, respectively, of the leg 35. The wall 40 merges into one side of side wall 43 and into one side of side wall 42. The wall 4| merges into a portion of the length of the lower end of side wa1l'43. The latter is of greater width than wall 42 and has its lower end spaced from the lower end of rear wall 40. The lower end of leg 36 is of rectangular contour and is provided with an outwardly directed flat flange 44 which seats upon, is secured to and is of the same contour as an outwardly directed flange 45 at the upper end of stretch 34 of section 20. The holdfast means between the

flanges

44, 45 is indicated at 46 (Figure 4).

The stretch 34 is of rectangular cross section and includes a rear wall 41, a front wall 48, and a pair of

side walls

49, 5|] formed lengthwise thereofwith slots 5|, 52 respectively. The slot 5| is of greater length than slot 52. The lower portions of the

walls

49, 56 are of greater thickness than the

portions

53, 54 are oppositely disposed curved vertical. legse55,.56, respectively, formed at their lower ends with outwardly directed

foot pieces

51, 58, respectively, which are anchored, as at 59, to the base 60 of a supporting structure 6| to be more fully referred to. The stretch 34 is open at its upper and lower ends as is clearly shown in Figure 4. The lower ends of the walls of the stretch 34 are of arcuate contour. The Walls 41,

48 have extended therefrom at the upper end of slot 52 a pair of outwardly directed and downwardly inclined apertured ears 62, and a combined detector and deflector element 63 for light coins, slugs, discs, or a substitution for a good coin. The element 63 functions to deflect the light-coins in a direction to cause them to discharge from the passage 64 formed by the stretch 34. The light substitutions for good coins are discharged through slot 5 I. The element 63 includes a lever substantially of semi-oval contour and formed of an outer end part 65 and upper and

lower arms

66, 61, respectively, normally disposed at a downward inclination with respect to stretch 34. The arm 66 has its top formed with an upstanding extension 68 of'channel-like form open at each end. The extension 68 is adapted to receive the light substitution for the good coin in its travel downwardly in passage 64. Merging into the upper end of the outer end part 65 is a downwardly inclined threaded bar 66 carrying an adjustable counterweight 68 acting to maintain the lever 63 in the position shown in Figure 4. The arm 66 extends through the upper end of slot 52 in a downwardly inclined direction towards the slot 5| below the upper end of the latter. The slot 5| extends above the upper end of slot 52. The upper end of the outer end part 65 is arranged between the ears 62 and is loosely mounted on a pivot 68 carried by ears 62. The arm 61 has its free end normally abutting the wall below the bottom of slot 52 and constitutes a stop for limiting the shifting movement of lever 63 by the counterweight 68 and to provide for arm 66 to extend across the passage 64 in the path of the coins and substitutions for the latter. When a good coin or a substitution for the latter corresponding in weight to the good coin travels downwardly in passage 64 and impacts arm 66, the latter will be lowered and swung outwardly to an extent to permit for the good coin or substitution to continue its travel in a direction to be discharged from the lower end of stretch 34. When the substitution for a good coin is of less weight than the latter, it does not rock lever 63 and is deflected through slot 5|.

The good coin substitution, whether it be a solid disc, slug, blank or counterfeit or an annulus or an apertured disc, slug or blank, will be hereina'fter referred to as slug.

The combined slug detecting, good coin directing and coin and slug discharging mechanism acts upon a slug, which has passed through stretch 35 of element l8, to prevent it from being directed to the point of destination for a good coin and which also acts to direct the good coin into a conducting means leading to the point of destination for the good coin. The said mechanism is mounted on the supporting structure 6| and the latter will not be referred to. The base 6|] of the structure 6| has a thickened intermediate portion 69, a forward vertical arm 10 at the front end of base 66, a rear vertical arm H at the rear end of base and of less height than arm 10, a vertically disposed L-shaped bracket 12 having its horizontal leg integral with the rear face of arm 1| above the bottom of the latter and its vertical leg extended above the upper end of arm 1 I, and a pair of spaced parallel

intermediate arms

13, 14 integral with the ends of the thickened portion 99. The arm 13 is of greater height than arms 1|, 14 and is arranged in parallel spaced relation to arm 1 I. The arm 14 is of less height than and is'disposed in parallel spaced relation to arm 19. The latter is suitably anchored to the inner face of support I. The arm 19 is formed with an opening 15 which registers with an opening 19 formed in support I. The arm 14 has an opening 11 of greater diameter than and which aligns with opening 15. The arm 13 is formed with an opening 18 of less diameter than and which aligns with opening 11. The arm II has an opening 19 of less diameter than and which aligns with opening 11. The vertical leg of bracket 12 is formed with a threaded opening 89 which aligns with opening 19. The vertical leg of bracket 12 is reduced at its upper end, as at 8I, and formed with an opening 82 which aligns with an opening 83 formed in the upper end of arm 13. The thickened portion 69 of base 99 is formed with a transversely extending flared slot 84, a concavity 85 (Figures 3 and '7) in its upper face between slot 84 and arm 13, a depending tubular part 86 on its lower face between slot 84 and arm 13, and an opening 81 which communicates with concavity 85 and part 86.

The slug detecting and good coin directing and coin and slug discharging mechanism includes a shaft 88 having a collar 89 fixed thereto intermediate its ends. The shaft 88 is the operating shaft of said mechanism and at its outer end is fixed to a turning knob 90 therefor arranged exteriorly of support I. The knob 99 is formed in its inner face with a socket 9| into which extends a stationary bearing 92 for the knob. The bearing 92 is of cap-shaped form and encloses a stationary annulus 93 which encompasses in spaced relation the collar 89. A controlling spring 94 for the shaft 88 is interposed between and fixed to the collar 89 and annulus 93. The bearing 92 and annulus 93 are connected together by spaced holdfast means 95 which engage in the support I for anchoring the bearing and annulus stationary against the outer face of support I.

Encompassing, slidably coupled to, and revolved by the shaft 88 is a slidable spring controlled revoluble outer shaft structure 96 for carrying and shifting a front clutching element to be referred to. The structure 96 includes an outer tubular part 91, an intermediate part 98 and a head 99. The inner portion of the part 91 is of greater outer diameter than the remaining portion thereof and corresponds in outer diameter to that of the said part 98. The head 99 is of materially greater diameter than and is disposed concentrically with respect to part 98. The part 91 merges into the part 98. The latter merges into the head 99. The part 91 is slidably mounted on shaft 88, extends into the openings 15, 19 and is formed at the inner end of its portion of smallest outer diameter with a pair of diametrically disposed slots I09 lengthwise thereof. The shaft 88 is provided with a diametrically extending pin I9 I for coupling the shaft structure 99 therewith to provide for the revolving of the latter on the operation of shaft 88. Carried by that'portion of part 91 of smallest outer diameter is a flanged collar I02 and a fixed annular abutment I93 arranged in spaced relation to the collar I92. The latter is shiftable lengthwise on part 91. The pin I9! extends into collar I92 and constitutes a stop for collar I02 when the latter is shifted in a direction towards head 99. interposed between collar I02 and abutment I93, as well as encompassing part 91, is a coiled controlling spring I94 acting to return shaft structure 99 to its normal position,

such as shown in Figure 3. The head 99 consists of a circular body part I05 having a cam face I96 coacting with a stationary cam I01 fixed to arm 14 to provide for the shaft structure 99 being shifted inwardly on the operation of shaft 83 from knob 99. The other face of body part I95 has extending therefrom upper and lower oppositely disposed semi-circular flanges I98, I99 respectively. The flange I08 is of less width than the flange I99 and encompasses an edge portion of a front clutching element IIO to be referred to. The flange I99 encompasses and extends beyond the remaining edge portion of element H0. The flange I99 constitutes a support for a good coin or a slug. The front clutching element is designated H9 and includes (Figure 6) a disc III which opposes the rear face of body part I 05. The disc I I I is formed with an axially arranged opening H2 in which is countersunk the head of a screw H3 threadedly engaging with the wall of a threaded socket I I4 formed axially of the shaft structure 96 and opening at the rear face of head part I95. The disc III, in proximity to its outer edge is formed with a circular row of spaced openings H5 in which are slidably mounted combined finder and clutch pins H9 having bearing against the heads thereof, spaced radially disposed resilient arms II1 (Figures 5 and 6) of a carrier II8 mounted axially thereof upon the screw I I3. Secured upon the latter and bearing against the carrier H8 is a binding nut II9 for clamping the central portion of the latter against the central portion of the disc I I I.

Aligning in spaced relation with respect to the shaft structure 99 is a springcontrolled adjustable revoluble rear shaft structure I29 in cluding a shaft I2I formed of a front part I22 and a rear part I23 of less length and diameter than that of part I22. The junction of the parts I22, I23 form shaft I2I with a peripheral shoulder I24. The parts E22, I23 are mounted respectively in the

openings

18, 19. The front end of front part I22 is integral with the rear face of a disc-like head part I25 formed at its edge with a cam I29 best shown in Figure 7. The purpose of cam I29 will be presently referred to and its normal position thereof is as shown in Figures 2 and '7. Carried by and arranged in spaced relation to the front face of head part I25 is a rear clutching element I21 constructed in the same manner as and oppositely disposed with respect to clutching element H9. The element I21 is secured to head part I25 in the same manner as clutching element I Illis secured to head part I953. The part I29 has mounted in its rear end a thrust bearing I29 of globular form which abuts the front end of a peripherally threaded adjusting member I29 for shaft I2I. The member I29 extends through and has threaded engagement withthe opening 89 in the vertical leg of bracket 12. A holding nut I89 is carried by member I 29 exteriorly of said vertical leg. The latter and the arm 13 are connected together by a threaded tie rod IBI which is seated in opening 83, extended through opening 82, and carriesa pair of securing nuts I32 abutting the front and rear faces of the reduced part 8| of the vertical leg of bracket 12. The shaft iEI revolves in the openings l8, l9 against the action of a controlling spring I33 having one end fixed to part I22, as at 84, and its other end extended and passed through rod I3I, as at I35. The slidably mounted combined finder and clutch pins of the element I21 are indicated at I36.

The finder and clutch pins of the clutching elements are so arranged and constructed that they will catch on certain letters or engravings on the good coins for the purpose of gripping the coins so that the shaft structures 96, I20 will be clutched to simultaneously revolve whereby a deflector device, to be referred to, will provide for the good coins to travel in a direction towards the point of destination therefor. The finder and clutch pins will not clutch and associate with the faces of the slugs in a manner to provide for clutching the shaft structures 96, E29 together to cause them to revolve in unison. When the structures 96, I20 are not clutched together, the slug carried by the head part of shaft structure 96 will be discharged from the latter on the revolving of the structure 96 independent of structure I29. The deflector device normally closes the'conducting off means, to be referred to, for the good coins and is operated to open said conducting off means by the cam I26. The deflector device also constitutes means to prevent the slugs from travelling in the direction provided for the good coins. The deflector device indicated generally at I31 and best shown in Figure '7 includes a vertically movable plunger I38 arranged in the tubular part 86 and opening 81 and normally extending into the cavity 85 in the path of the cam I26 on the edge of the head part I25. The lower end of plunger I38 merges into an inclined arm I39 having a lower end terminal portion I40 (Figure 3) disposed at right angles to the remaining part of arm I39 and extended through an opening I4I formed in the small end I42 of a substantially triangular shaped plate I43, which in proximity to opening MI is fixed to a rock shaft I44, carrying a deflector member I45 (Figure 4) formed of a lower horizontal leg I46 and an upstanding leg I41 of greater length than leg I46. The plate I43 also acts as a counterbalance for shaft I44 due to the fact that the latter is connected to the plate I43 eccentrically of the latter. The leg I41 extends through and is anchored to shaft M4. The leg I46 extends from the lower end of leg I41 and is arranged below shaft I44.

Anchored to the base 60' is an upstanding stop member I48 formed at its upper end with an inwardly extending leg I49 arranged in the path of cam I26 for arresting the upward travel thereof.

Secured to and depending from the base 60 is a hollow directing element I59 of frusto-tapered contour formed of a body part I5I merging at its bottom into a pair of oppositely disposed outwardly directed inclined branches I52, I53 to which are coupled or secured, as at I54, a good coin directing chute and a slug carrying off chute I55, I56, respectively. The chute I55 is adapted to lead to the point of destination, not shown, for a good coin. The chute I56 is shown, by Way of example, as leading to and discharging into a slug receiver I56 (Figure 1) arranged at the front of support I. The bottom of the body part I5I and the inner side of branch I52 are open, as at I56 to provide a clearance for leg I41 of member I45. The shaft I44 extends through the body part I5I in proximity to the bottom 01' the latter. The member I45 is arranged in body part I5I. The upper end of body part I5I registers with the slot 84. The normal position of leg I46 of member I45 is as shown in dotted lines, Figure 4, whereby branch I52 is closed. When cam I26 depresses plunger I38 (Figure '1), shaft I44 is rocked in a direction to move member I45 to the full line position (Figure 4) whereby branch I53 is closed and leg I41 swung into the branch I52 to be positioned in the path of the good coin, the latter impacts leg I41 which in connection with the plate I43 will cause the shaft I 44 to be rocked in the opposite direction moving member I45 to the dotted line position (Figure 4), closing branch I53, and opening branch I52 whereby the good coin will be permitted to pass from branch I52 into chute I55.

To prevent a pair of coins or slugs or a coin and a slug being supported simultaneously by the flange I09 of head part 99 of structure 96, a stop lever I51 (Figure 4) is employed. The lever I51 at its upper end is formed with a projection I51 which, when lever I51 is in active position, depends below the lower end of stretch 34 to be arranged rearwardly of clutching element IIO (Figures 3 and 4). The projection I51 prevents a coin or slug to be positioned between a coin or slug and the clutching element III). The lever i 51 is of arcuate contour and arranged forwardly of wall 48 and leg 56 of stretch 34. The lever I5? is pivoted at its lower end, as at I58, to a lateral lug I59 on leg 56. The pivoted end of lever I51 is formed with an angularly disposed nose I69 arranged in the path of the endedge I6I of flange I09. The upper end of lever I51, when the latter is active, engages under an offset part of a stop member I62 secured to the front face of wall 48 of stretch 34. When shaft structure 96 is revolved by shaft 88, the edge. I6I of flange I99 engages the nose I69 and shifts lever I51 upwardly whereby the projection I51 is swung clear of the pins of clutching element H0. The edge I 6| maintains the lever I 51 elevated until shaft structure 96 is returned to its inactive position. As shaft structure 96 is moved to its inactive position, lever I51 lowers by gravity until it assumes the position shown in Figure 4. To limit the upward shift of the lever I51, the wall 48 of stretch 34 is provided on its front face with a stop I62 (Figures 3 and 4) positioned in the path of the top edge of the lever. The latter on the front face thereof and directly above projection I51 is weighted, as at I63, to assist in the lowering of the lever to normal position.

To prevent the passage of an axially apertured slug or a coin substitution in the form of an annulus upon the detector element 21 is a detector I64 consisting of an upwardly disposed inwardly inclined rod I65 having its upper end arranged at the opening 2I in head 2I (Figures 1 and 2). The opening 2| is of greater diameter. than that of a good coin or slug. The upper end of rod I 65 constitutes a support for and a stop to arrest a good coin or solid slug from dropping through opening 2I If an axially apertured slug or a coin substitution in the form of an annulus is discharged from slide 6 over opening 2 I, it will be taken up by rod I65 and pass downwardly on and be retained by the rod. The rod I65 is removably supported by the overlapped slotted upper part I66 of an inwardly inclined bracket I61 secured to the inner face of support I below the head 2I. The rod I65 has a laterally extended combined stop and lifting bar I68 adjacent its lower end. The bar I68 seats on a washer I69 on the upper end of bracket I61.

The operation of the combined slug detecting, good coin directing and coin and slug discharging mechanism will now be referred to. The

coin or slug travels down the chute-like stretch 34 of section 20. If the slug is of light weight it will be deflected by the arm 66 of element 63 from the stretch 34 through slot The coin 5 will depress arm 64 and pass into the lower portion of stretch 34. The slug will do likewise if the weight thereof corresponds to that of the coin. The coin or the slug passes from stretch 34 and falls upon the semi-circular projection or flange I09 at the inner end of structure 96. The projection I09 is normally held at the bottom of the structure 96 by the spring controlled knob 90. When the coin or slug is deposited in projection I 09 it is arranged between the elements H0, I21, and the cam'I26 is up against the leg I49 of stop member I48. Now by turning knob 90 to the right, it also turns structure 96 and causes the latter to be shifted inwardly to provide for the coin or slug to be engaged by the pins II6, I36. The inward shift of the structure 96 is had through the medium of cam I01 acting upon body part I05. When the structure 96 makes one-half turn, it springs back by the pressure of spring I04 and releases the coin or slug. When the projection I09 is at the top of structure 96 and the coin or slug released, the coin or slug then drops through slot 84 into the chute-like directing element I50. The knob 90 makes only one-half turn and is forced back by the spring 94. The knob 90 operates shaft 88. The structure 96 turns in unison with shaft 88 and knob 90. The clutching elements II 0 and I21 are fastened solid to the structures 96, I 20 respectively. When a coin is deposited upon projection I09 and knob 90 turned to the right,

the pins II 6, I36 catch on the lettering or engraving on each side of the coin and which will provide for the structures 96 and I20 turning in unison. On the turning of structure I20 the cam 40 I26, which is fixed to and moves with the structure I20 pushes down the plunger I38, which in turn will actuate the arm I39 whereby element I will be shifted to a position to permit of the coin passing into branch I52 of the element 45 I50. If a slug with smooth side faces was deposited upon projection I09, the pins or feelers would not catch in the side faces of the slug and under such conditions the structure I20 would not turn and operate element I45 whereby when the slug is discharged from projection I09 it will pass through slot 84 into element I50 and be conducted off through branch I53.

The purpose of the projection I51 of the lever 55 I51 is to keep a leading coin or slug straight up and down when it is supported by the projection or flange I09. This provision prevents a following coin or slug passing between the pins H6 and the supported coin or slug in case the. latter has not been discharged. The weight I63 functions to normally maintain the lever I51 in the position shown in Figure 4 whereby the projection I51 will hold, a coin or slug deposited on the projection or flange I09, in opposed relation 5 to the pins H6 and in line with the passage of section 20. When structure 96 is turned from normal position for the purpose referred to, an end edge of the projection or flange I09 will engage the nose I60 on the lever I51 and the latter 70 will be raised to an extentto have its projection I51 moved clear of the element IIO.
