Definitions

  • This invention has reference to improvements in coin controlled apparatus,-and its object is to provide a device which will selectively discard spurious devices and direct genuine coins to the coin controlled lock of the vending apparatus.
  • the present invention is designed to operate in conjunction with any suitable coin lock and vending apparatus," and consequently such devices having nothing to do with the present invention are neither here in illustrated nor described.
  • vending machines It is customary to unlock vending machines by means of a coin of suitable size and shape and occasionally a check or token of like size and shape is utilized for the legitimate operation of the vending machine. Malicious or fraudulent operation of the machine is customarily attempted by the employment of metal orrother slugs, or the use of wires or some such picking devices, and sometimes it is attempted to operate the machine by badly worn coins.
  • the coin chute is provided with an entering opening of a size to just receive a genuine and relatively unworn coin of the denomination for which the machine is set.
  • the coin chute is constructed, as by making it tortuous, so as to be proof against the introduction of wires or other devices by which the coin lock may be picked.
  • the device is provided with magnetic means for diverting iron slugs or the like away from the proper path for a genuine coin.
  • the device is provided with weight responsive means for discarding all light slugs or coins which mi ht be introduced into the machine, even t ough such light coins be genuine, but because of being of the wrong denomination, or being worn, will not constitute proper payment for the articles to be vended.
  • Genuine unworn coins have certain characteristics wherein they differ from spurious devices usually employed to improperly cause the unlocking of the vending devices, and these characteristics of genuine coins are relied some parts bein upon for directing such genuine coins to the com lock and discarding either worn genuinc coins or slugs of suitable size and weight which might otherwise get by the fraud preventive devices, and so reach and cause the operation of the vending mechanism to deliver an article from the vending side of the machine.
  • coin will be used hereinafter for designating genuine coins of desirable condition, and also authorized checks or tokens, while the term slug will be employed to designate all spurious devices usually em loyed by persons desiring to obtain articles from the vending machine without the use of a pro er coin.
  • T e present invention is designed to direct all proper coins into the proper chan- .nels to cause the operation of the vendi machine and to direct-all slugs into a discar channel by means of which such slugsand even genuine coins of improper denomination or unduly worn, are returned to the exterior of the machine, whereby the fraudulently inclined .o rator is notified of the futility of his orts, while genuine coins other than those desired in payment for the articles to be vended are returned to the owner and the latter sufi'ers no loss.

  • the s'pacingmember 4 is located ates 1"and2 and may be quite narrow and is nearly as long as the corresponding edges of the plates, these plates being longer in one direction than the other.
  • the spacing member 5 conforms along one edge to the shape of the corresponding edges of the plates 1'and2 which ma be inset for a ortion of the lo'ng edge, as indicated at 9, a though'this is not essential, except that it saves material.-
  • the spacing block or strip 5 stops short of one end of the plates 1 and 2, which end may be termed the upper end, since these plates are usually installed in the upright position, and the upper end of the strip 5 has an inward extension 10, that is, the prolongation 10 extends toward the opposite edge of the plates 1 and 2 or toward the strip 4, while the upper and lower edges 11, 12, respectively of the extension 10 approach one toward the other toward the inner end of the extension 10, so that both edges are inclined to the horizontal, and the upper edge 13 of the plates 1 and 2 may incline in substantial parallelism with the edge 11 of the extension 10.
  • the stri or member 5 has an inwardly declinjng edge 14 extended toward the strip 4 and this edge terminates in an in-cut portion 15 of the strip or member 5, which is widened below this in cut portion 15, as indicated at 16, the inner edge 17 of this widened portion 16 being upright.
  • Theblock or spacing member 6 has a taper extension 21 entering the space between the edges 12 and 14 of the spacing member 5 about midway. thereof and mid- Way of an upright inner edge portion 22 of the strip 5 between the edges 12 and 14. That'end of the block remote from the prolongation 21' has an edge portion 23 substantially parallel with and appropriately spaced'f-rom the inner edge of the strip 4,

  • the block 8 has an upper edge portion 34 inclining toward the edge 33 and terminating in a doubly inclined nose 35 merging at one side into the corre-' sponding end of the edge 34 and at the other side into the upper end of the edge 32 and located to one side of the center line of the space defined between the edges 17 and 28,- the side of said center line occupied by the nose 35 being toward the strip 5.
  • a magnet 36 having polar extremities 37 spaced from the lower end of the edge 11 in substantial alinement with the portion of the coin chute determined by such edge 11.
  • This magnet may be of thefamiliar horseshoe type, held in place by a clip 38 and having a portion constituting the lower edge of the magnet when installed covered by a plate 39 of non-magnetic material or provided with any other means for preventin direct magnetic contact.
  • the momentum acquired, however, in addition to the force of ravity tending to cause the iron article to fafi toward the block 6 will carry such iron article around the'lower polar extremity 37 and for a short distance toward the yoke end of the magnet, but on reaching the non-magnetic material 39 the magnetic attraction is greatly weakened and the force of gravity and momentum cause the iron article tofall on to the edge 26 to be, directed thereby into the passageway between the innor edge of the strip 4 and the corresponding edges of the blocks 6, 7 and 8.
  • the passageway 40 thus defined may be termed the discard passageway or chute, and by means of suitable chutes, not shown, may lead to the exterior ofthe machine to cause ejection of the slugs reaching the passageway.
  • the coin or slug introduced is not of magnetic material, then it will roll down the edge 11 until it strikes the polar extremities 37 when not being attracted thereby, its momentum is arrested and it falls betwecn the inner end of the extension 10 and the polar extremities-37. until it ultimately strikes the edge 24 which declines in the opposite direction from the edge 11 and in substantial parallelism with the declining lower edge 12 of the extension 10.
  • the coin or non-magnetic slug now gains momentum by rolling down the edge :24 and proceeds toward the edge 22 of the strip 5 and the direction of travel of the coin or slug is diverted by the edge 22 on to the declining edge 14, which declines reversely to the edges 12 and 24 and by this edge 14 is'directed toward a section 41 of the coin chute laterally enlarged by the insetportion 15, but below the same contracting to approximately the diameter of a genuine coin betweenthe edges 17 and 28.
  • the receiving end of the section 41 of the coin chute 1s normally obstructed by a shelf 42 approximately bridging the space between the lower end of the edge 14 and the upper 'endof the edge 30.

  • the lever 43 is shown as a lever of the first order with the longer arm carrying the shelf 42 and the shorter arm provided with a weight 47 sufiicient to slightly overbala-nce the shelf 42 and hold it in obstructing relation to the upper end of the coin chute section 41.
  • the plate 2 is appropriately slotted, as indicated at 48, for a sufficient rocking of the lever 43 to permit movement of the shelf 42 out of obstructing relation to the coin chute section 41.
  • the shelf 42 will remain in traversing .relation to the chute section 41, since the weight of the coin or slug is insufiicient to overbalance the weight 47 and consequently the coin or slug will pass over the shelf 42 on to the upper edge or ledge 30 of the block or strip 7 and be directed by the latter into the discard chute 40 to be returned to the exterior of the machine.
  • the shelf 42 will give-to the superior weight and the article reaching the shelf 42 will drop into the coin chute section 41, the shelf 42 being of a width equal to that of the chute section 41 and the inset portion 15 of the strip 5, thus giving time while the article rolls over the shelf 42 for the latter to yield to the superior weight and cause the article to drop into the coin chute section 41.
  • the article is, of course, of no greater diameter than a coin of proper denomination, for it otherwise could not be introduced through the guard plate at the entrance end of the coin chute, so that any article finally reaching the coin chute section 41 must be of a diameter not greater than that of a proper coin and of a weight not materially less than that of a proper coin, but may be of greater weight and less diameter, and may also be a genuine coin worn quite smooth.

WILLIAM ISAAC RAVEBT, 0F HAZLETON, PENNSYLVANIA, ASSIGNOR TO STANDARD VENDING MACHINE COMPANY, OF HAZLETON, PENNSYLVANIA.
COIN-CONTROLLED APPARATUS.
Specification of Letters Patent.
Application filed April 22, 1913. Serial No. 762,959.
To all whom it may concern:
Be it known that I, WILLIAM I. Ravnn'r, a citizen of the United States, residing at Hazleton, in the county of Luzerne and State of Pennsylvania, have invented a new and useful Coin-Controlled Apparatus, of which the following is a specification.
This invention has reference to improvements in coin controlled apparatus,-and its object is to provide a device which will selectively discard spurious devices and direct genuine coins to the coin controlled lock of the vending apparatus.
The present invention is designed to operate in conjunction with any suitable coin lock and vending apparatus," and consequently such devices having nothing to do with the present invention are neither here in illustrated nor described.
It is customary to unlock vending machines by means of a coin of suitable size and shape and occasionally a check or token of like size and shape is utilized for the legitimate operation of the vending machine. Malicious or fraudulent operation of the machine is customarily attempted by the employment of metal orrother slugs, or the use of wires or some such picking devices, and sometimes it is attempted to operate the machine by badly worn coins.
In accordance with the present invention 4 the coin chute is provided with an entering opening of a size to just receive a genuine and relatively unworn coin of the denomination for which the machine is set. The coin chute is constructed, as by making it tortuous, so as to be proof against the introduction of wires or other devices by which the coin lock may be picked. Furthermore, the device is provided with magnetic means for diverting iron slugs or the like away from the proper path for a genuine coin. Moreover, the device is provided with weight responsive means for discarding all light slugs or coins which mi ht be introduced into the machine, even t ough such light coins be genuine, but because of being of the wrong denomination, or being worn, will not constitute proper payment for the articles to be vended. Genuine unworn coins have certain characteristics wherein they differ from spurious devices usually employed to improperly cause the unlocking of the vending devices, and these characteristics of genuine coins are relied some parts bein upon for directing such genuine coins to the com lock and discarding either worn genuinc coins or slugs of suitable size and weight which might otherwise get by the fraud preventive devices, and so reach and cause the operation of the vending mechanism to deliver an article from the vending side of the machine.
For convenience of description the term coin will be used hereinafter for designating genuine coins of desirable condition, and also authorized checks or tokens, while the term slug will be employed to designate all spurious devices usually em loyed by persons desiring to obtain articles from the vending machine without the use of a pro er coin.
T e present invention is designed to direct all proper coins into the proper chan- .nels to cause the operation of the vendi machine and to direct-all slugs into a discar channel by means of which such slugsand even genuine coins of improper denomination or unduly worn, are returned to the exterior of the machine, whereby the fraudulently inclined .o rator is notified of the futility of his orts, while genuine coins other than those desired in payment for the articles to be vended are returned to the owner and the latter sufi'ers no loss.
The invention will be best understood from a consideration of the following detailed description, taken in connection with the accompanvin drawings forming a part of this specification, with the. further understanding that while the drawings show apractical embodiment of the invention,.the atter is not confined to any strict con-v formity with the showin of the drawings, but may be changed and modified so-long as such changes and modifications mark no material departure from the'salient. features of the invention,
In the drawings: Figure 1 is a face elevation of the fraud preventing devices of the present invention. Fig. 2 is an edge or side elevation of the structure of Fig. 1' as viewed from the right hand side thereof. broken away to reveal some of the interior construction. Fig. 3 is a section on the line3-43 of Fig. 2. Fig. 4 is a section on the line 44 of Fig. 1 drawn on a larger scale and showing some parts in elevation which would be otherwise cut by the section. Fig. 5 is a section on the line 5-5 of Fig. 1, drawn on a larger scale and showing one phase of operation of-the device. Fig. 6 is a section on the line 6-6 of Fig. 1 but drawn on a larger scale and showing a different phase of operationfrom Fig.
5. Fig. 7 is a section similar to Fig. 5 but showing a different phase of operation from the showing of Fig. 5. Fig. 8. is a detail view of an operating lever employed in the structure. Figs. 9,10 and 11 are yiews from different sides of a pii'ot structure employed for carrying the lever -of Fig. 8 and for other purposes, Fig.,10 being partly in section Fig. l2 is 'a detail view'of' a spring employed in the structure. l
In the drawings all showing of the vending apparatus andfthe coin lock which may be employed in conjunction therewith has beenomitted, and all showing of the usual casing'iinclo'sing such structures has also been'jomitted, since these parts may follow any known or approved practice,fand"in themselves have nothing to do with the present invention which re'lates to means for prenear one edge of the p venting the fraudulent operation"of'the.
vending side of a vending'machine. There are provided two plates l and2 held together by SCIeWS3flI otherwise, and spaced apart by filling-in blocks or strips 4, 5, 6, 7
and 8, which are thus particularly jmentioned for reference hereinafter. The blocks 4 to 8 may be all' 'of substantially the same thickness which shouldbe little more'th'an that of the proper coin designed to provide for the unlocking of the vending side of the machine. The s'pacingmember 4 is located ates 1"and2 and may be quite narrow and is nearly as long as the corresponding edges of the plates, these plates being longer in one direction than the other. The spacing member 5 conforms along one edge to the shape of the corresponding edges of the plates 1'and2 which ma be inset for a ortion of the lo'ng edge, as indicated at 9, a though'this is not essential, except that it saves material.- The spacing block or strip 5 stops short of one end of the plates 1 and 2, which end may be termed the upper end, since these plates are usually installed in the upright position, and the upper end of the strip 5 has an inward extension 10, that is, the prolongation 10 extends toward the opposite edge of the plates 1 and 2 or toward the strip 4, while the upper and lower edges 11, 12, respectively of the extension 10 approach one toward the other toward the inner end of the extension 10, so that both edges are inclined to the horizontal, and the upper edge 13 of the plates 1 and 2 may incline in substantial parallelism with the edge 11 of the extension 10. At a point a short distance above the inset portion 9 of the plates 1 and 2 the stri or member 5 has an inwardly declinjng edge 14 extended toward the strip 4 and this edge terminates in an in-cut portion 15 of the strip or member 5, which is widened below this in cut portion 15, as indicated at 16, the inner edge 17 of this widened portion 16 being upright. Below the widened portion'1G there is another incut portion 18 of the strip 5 merging into a declined angle portion 19, which in turn merges into an uprightedge portion 20 all along the inner edge of the strip or spacing member 5.
Theblock or spacing member 6 has a taper extension 21 entering the space between the edges 12 and 14 of the spacing member 5 about midway. thereof and mid- Way of an upright inner edge portion 22 of the strip 5 between the edges 12 and 14. That'end of the block remote from the prolongation 21' has an edge portion 23 substantially parallel with and appropriately spaced'f-rom the inner edge of the strip 4,
while the prolongation 21 has an upper edge 24.. substantially parallel with the edge 12,
' and at the end remote from the edge 22 of the s'trip'5 rounding upwardly, as indicated at 25, and merging into a declined continuation'26 joining the upper edge of the end 23 and where the edges 25 and 26 join there is formed a nose 27.
The block or-spacing strip? has one edge -28 spaced from and substantially parallel with the edge 17 of the strip 5 andanother edge 29 spaced from and substantially parallel with the inner edge of the strip 4. This strip i has sin-upper end 30 declining from the edge 29-and a lower edge 31 also declining toward the same edge 29, and this strip or spacing member 7 has its upper edge 30 at a point somewhat lower than the lower end of the edge 14 and its lower edge 31 about opposite the upper edge of the declined angle, or bevel portion 19 of the spring 5.
The spacin block 8 has an upright edge 32 parallel with, but spaced from the edge 20. of the strip 5, and a shorter upright edge 33 opposite the edge '32 and substantially parallel with, but spaced from the inner edge of the strip 4. The block 8 has an upper edge portion 34 inclining toward the edge 33 and terminating in a doubly inclined nose 35 merging at one side into the corre-' sponding end of the edge 34 and at the other side into the upper end of the edge 32 and located to one side of the center line of the space defined between the edges 17 and 28,- the side of said center line occupied by the nose 35 being toward the strip 5.
It is customary to provide coin operated "machines with-a coin slot, in a suitable plate,
of a size to freely yet snugly receive a coin of suitabledenomination, but to prevent the introduction of any articles of larger size either in diameter or thickness, and it is assumed that the present structure when installed upon a vcnding'machine is guarded by such an entrance plate.
The edges 11 and 13, 12, 24, 22 .and 14, the
edges 17 and 28, and the edges 19, 20 and 32,
I gravity, acquiring a certain moment-um.
However, in the path of a coin so rolling there is introduced a magnet 36 having polar extremities 37 spaced from the lower end of the edge 11 in substantial alinement with the portion of the coin chute determined by such edge 11. This magnet may be of thefamiliar horseshoe type, held in place by a clip 38 and having a portion constituting the lower edge of the magnet when installed covered by a plate 39 of non-magnetic material or provided with any other means for preventin direct magnetic contact.
f it be assumed that instead of a coin an iron disk or any other iron or steel object be introduced into the machine so as to be free to move along the declined edge 11 by gravity, it will upon reaching the end of the extension 10 tend to gravitate toward the block 6, but the momentum acquired in rolling down the edge 11 will project the iron article into engagement with the polar extremities 37 and the magnetic attraction established in the absence of other forces holds the iron article to such polar extremities. The momentum acquired, however, in addition to the force of ravity tending to cause the iron article to fafi toward the block 6 will carry such iron article around the'lower polar extremity 37 and for a short distance toward the yoke end of the magnet, but on reaching the non-magnetic material 39 the magnetic attraction is greatly weakened and the force of gravity and momentum cause the iron article tofall on to the edge 26 to be, directed thereby into the passageway between the innor edge of the strip 4 and the corresponding edges of the blocks 6, 7 and 8. 'The passageway 40 thus defined may be termed the discard passageway or chute, and by means of suitable chutes, not shown, may lead to the exterior ofthe machine to cause ejection of the slugs reaching the passageway. Suppose, however, that the coin or slug introduced is not of magnetic material, then it will roll down the edge 11 until it strikes the polar extremities 37 when not being attracted thereby, its momentum is arrested and it falls betwecn the inner end of the extension 10 and the polar extremities-37. until it ultimately strikes the edge 24 which declines in the opposite direction from the edge 11 and in substantial parallelism with the declining lower edge 12 of the extension 10. The coin or non-magnetic slug, as the case may be, now gains momentum by rolling down the edge :24 and proceeds toward the edge 22 of the strip 5 and the direction of travel of the coin or slug is diverted by the edge 22 on to the declining edge 14, which declines reversely to the edges 12 and 24 and by this edge 14 is'directed toward a section 41 of the coin chute laterally enlarged by the insetportion 15, but below the same contracting to approximately the diameter of a genuine coin betweenthe edges 17 and 28. The receiving end of the section 41 of the coin chute 1s, however, normally obstructed by a shelf 42 approximately bridging the space between the lower end of the edge 14 and the upper 'endof the edge 30. Thisshelf is carried on one end of a lever 43 pivoted at 44 on the free end of a bracket 45, the other end of which is made fast to the plate 2 by a screw 46 or otherwise. The lever 43 is shown as a lever of the first order with the longer arm carrying the shelf 42 and the shorter arm provided with a weight 47 sufiicient to slightly overbala-nce the shelf 42 and hold it in obstructing relation to the upper end of the coin chute section 41. The plate 2 is appropriately slotted, as indicated at 48, for a sufficient rocking of the lever 43 to permit movement of the shelf 42 out of obstructing relation to the coin chute section 41.
If the article introduced intothe coin chute and reaching the shelf 42 be a genuine coin, but of another denomination and lighter than the one designed to cause operation of the vending apparatus, or if the coin of the proper denomination be so badly worn as to be relatively light,or if the artlcle introduced be a nonmagnetic slug of a material making it relatively light in weight, then the shelf 42 will remain in traversing .relation to the chute section 41, since the weight of the coin or slug is insufiicient to overbalance the weight 47 and consequently the coin or slug will pass over the shelf 42 on to the upper edge or ledge 30 of the block or strip 7 and be directed by the latter into the discard chute 40 to be returned to the exterior of the machine. Suppose. however, that the article introduced be of sufficient weight on reaching the shelf 42 to overba-lance the retaining weight 47, then the shelf 42 will give-to the superior weight and the article reaching the shelf 42 will drop into the coin chute section 41, the shelf 42 being of a width equal to that of the chute section 41 and the inset portion 15 of the strip 5, thus giving time while the article rolls over the shelf 42 for the latter to yield to the superior weight and cause the article to drop into the coin chute section 41. The article is, of course, of no greater diameter than a coin of proper denomination, for it otherwise could not be introduced through the guard plate at the entrance end of the coin chute, so that any article finally reaching the coin chute section 41 must be of a diameter not greater than that of a proper coin and of a weight not materially less than that of a proper coin, but may be of greater weight and less diameter, and may also be a genuine coin worn quite smooth.
Let it be assumed that the article entering the coin chute section 41 is a circular article with smooth-or plain faces which would be the case with practically allslugs, and
would also be the case of a smoothly worn genuine coin. In order to dispose of any article entering the coin chute section 41 there is provided a mechanism which will automatically direct all genuine coins, which are not badly worn, into the space between the edges 20 and 32 constituting a terminal portion 49 of the coin chute designed to lead toward the coin lock of the vendin machine, while slugs or too smooth y worn genuine coins are directed between the edges 31- and 34 of the blocks 7 and 8 "constituting a branch channel 50 opening into the discard chute 40, so that such rejected slugs or coins are returned to the exterior of the machine. 'Tobring this action about there is provided a mechanism which will now be described. At a point about coincident with the lower end of the coin chute section 41 each plate 1 and 2 is provided with a respective horizontal slot 51, 52, the slot 51 being in the plate 1 and the slot 52 in the plate 2. The slots 51 and 52 are extended entirely across the plates and the two sections of each plate thus produced by the slots may be joined by the side strips4 and 5, so that the two plates, although each formed of two parts, may each be effectively one plate. At the respective ends of the'slots 51 and 52 and common to both are bearing brackets 53, 54, respectively, made fast tothe plates by screws or otherwise. Jouinaled at the ends in these brackets isa shaft 55 having two collars 56, 57, thereon in line with the coin chute section 41, while the end of the shaft 55 journaled in the bearing bracket 53 carries a gear pinion 58.
Fast to the plate 2 at the side of the coin chute section 41 toward the bracket 53 there is a bracket 59 secured by screws 60 or otherwise, and this bracket has an outset portion 61 straddling a corresponding part of the slot 52 in the plate 2. This outset ortion carries a pin or journal 62 projectmg in a direction away from the plate 2, while one'portion of the bracket 59 has a lateral extension 63 terminating in an angle flange 64 which-atone end carries a pin 65 directed toward the main portion of the bracket and at the other endis provided with a perforation or passage 66. The pin 65 constitutes a journal for one end of a hanger 67 which may be in the form of a flanged strip, the flanges imparting rigidity, while at the lower end, that is, the end remote from the pin 65, the hanger 67 is formed with two parallel spaced cars 68, 69, respectively. These ears have oblong journal bearings for shafts 70, 71, respectively. The
shaft 70 has the end remote from the ear 68 journaled in the bracket 53 and adjacentv the bracket 53 carries a pinion 72 in mesh with the pinion 58, and immediately adjacent to the pinion 72 carries another pinion 73 which may be a bevel pinion. In matching relation to the collar 56 the shaft 70 carries a like collar 74. The shaft 71 is journaled at the end remote from the ear 69 in the bracket 54, and in matching relation to the collar 57 the shaft 71 has a like collar 75. The two shafts 70, 71' are in approximate alinement and are located opposite the slot 52 and under certain circumstances may enter the slot for a dis-. tance. The hanger 67 is capable of swinging on the pin 65 to carry the adjacent ends of the shafts 70 and 71 toward and from the shaft 55, the bearings for these shafts being sufiiciently loose to ermit this slight angular displacement of t 1e shafts 70 and 71, such displacement being relatively very slight. The shaft 55 may be so mounted as to have practically no movement laterally of its longitudinal axis.
Mounted on the pin 62 is an operating lever 76 having a hub 77 fitting the pin 62 and extending lengthwise thereof, so as to space the lever an appropriate distance from the bracket 59. The lever 76 is shown as of the first order and at one end is formed mto a gear segment 78 suitably beveled to match the bevel gear 73 on the short shaft or roller 70 and when the lever 76 is suitably mounted on the pin 62 it may be held by a screw 79 and washer 80, as best shown in Fig. 4, the said gear segment 78 being curved on the axis of the hub 77 as a center.
At the end of the lever 76 remote from the segment 78 is an enlargement 81 designed to operate as a weight sufiicient to cause the lever 77 to rock in an appropriate direction to produce certain results to be described. Projecting from one side of the leveradjacent to the hub 7 0 is a lateral arm 82 having one edge formed into a shoulder 83 extend ing in a direction approximately radial to the hub 77' for an appropriate distance, and from the outer end of the shoulder 83 the same edge is continued as a curved shoulder 84 which when the parts are in a certain posit-ion has its radius extending from a stud 85 projecting from the plate 2 near the bottom thereof, and on this stud there is mounted a sub-lever 86 having One arm of a length to reach the arm 82 and there providedwith a laterally projecting member 87 which maybe either .a 'pin or roller designed to engage the shoulders 84 and 83 to move the lever 76 against the action of the weight 81 or to permit itto move under the action of the weight 81.
The lever 76 isprovided with two spaced teeth, 88, 89 projecting therefrom toward the plate 2 and these teeth are arranged in concentric relation to the pivotal axis of the lever 76 with the terminal portions of.
.and 89 are so disposed as to engage an angle extension 92 of a finger 93 projecting from the lower or free end of the hanger 67, and this hanger 67 is urged at its free end toward the plate 2 by a spring 94 which may be of the leaf type, and is made fast at one end to the plate 2 by a screw 95 or otherwise, while its other or free end is bifurcated, as indicated at 90, and is so disposed that the respective members of the bifurcated end bear individually upon journal extensions 97 of the respective short shafts or rollers and 71. The spring 94 tends to constantly maintain the adjacent ends of the rollers 70 and 71 toward the long shaft or roller 55, but the end 96 of the spring 94 will yield to a superior force permitting the correspondiug ends of the rollers 70 and 71 to be moved away from the roller and as will hereinafter appear this movement of the rollers 70 and 71 may be caused by the en gagement of the angle end 92th one or the other of the teeth 88 and. 89 ofthe lever 76.
Mounted on the flange 04 of the bracket 59 by means of a screw or pin 98 which may engage in the hole or perforation 66 of the flange 04, is an escapement lever 99 having the upper end formed into a nose 100 movable through a passage 101 in the plate 2 into and out of the coin chute section 41. The end of the escapement lever remote from the nose 100 is formed with an elbow 102 and at the end of the elbow there is rovided a finger 103 located and shaped to be moved into and out of the coin chute below the roller 71 through a passage 104 in the plate 2. The lever 99 is under the normal control of a spring 105 having one end passed through the body of the lever to one side of the Pivot pin-98 and the other end secured to the plate 2 as by a screw 106, The tendency of the spring is to maintain the lever 99 in a position which will cause the nose 100 to be in traversing relation to the coin chute section 41. while the beveledface 92 of the lug 91 is positioned to engage the elbow 102 and on the appropriate movement of the-lever 76 force the finger 103 into traversing relation to the coin chute and at the same time withdraw the finger 100 from such position.
In order that the course of either coins or slugs through the coin chute anddiscard passages may be followed, suitable sight openings 107 are provided in the plate 2 at various parts thereof. The course through the device of a magnetic slug and the course of either a slug or coin of such light weight as not to operate the shelf orbalance 12 has already been traced, and so need not be repeated. Suppose that a fiat brass, lead, copper or other metal slug of non-magnetic material and of the same weight as a proper coin reaches the balance 42, and by overcoming the balance drops down into the passageway 41. At this time'the weighted end of the operating lever 76 is raised and consequently the lug 91 has engaged behind the elbow 102, thus forcing the finger 103 in traversing relation to the coin' chute with thenose 100 withdrawn therefrom, and the tooth 89 is at the time engaged behind the angle extension 92 of the finger 93 and the hanger 67 together with the ends of the rollers 70 and 71 journaled therein has been rocked against the action of the spring 94,
so thatthe collars on the rollers are in the mostdistant position one from the other. The slug drops until arrested by the finger 103, and at this time is between the collars 56 and 7 1 and the collarsv 57 and 75, all as shown in Fig. 5. Suppose, now, that the lever 86 is rocked so as to release the operating lever 76 to movement, underthe action of the weight 81, thenthe gear segment 78 in mesh with the gear 73 causes a rotative movement of the shaft or roller 70. At the same time the tooth 89 moves out of engagement with the angle extension 92" of the finger 93 and the adjacent ends of the rollers 70 and 71 are released to the action of the spring 9.4, thus bringing the collars 74 and into engagement with the corresponding face of the slug and forcing the other face into contactwith the collars 56 and 57. While these movements are progressing, the lug 91 moves out of engagement with the elbow 102 and the spring 105 causes a rocking of the lever 99 to withdraw the finger 103 from the path of the slug and to interpose the nose 100 into the path of a slug or coin which may be subsequently introduced into the coin chute. These actions occur before the movement of the operating lever is completed, and the rotation of the rollers 55 and 70 cause the slug to be moved straight downwardly until it ultimately escapes from the collars engaging it and it drops on to the upper end of the spacing block 8 to that side of the apex of the introduced into thecoin chute, then it will follow the tortuous passage formed by the inclined edges of the members 5 and 6 until the shelf 42 is reached, and the coin being of sufiicient weight overbalances the shelf and drops into the passageway 41 and on to the retaining finger 103 interposed in the coin chute and on the movement of the operating lever in a proper direction the coin is engaged by the collars on the rollers and is moved by these collars toward the discharge end of the chute. The edge 28 of the block or strip 7 is cut away on opposite sides as shown at.108, so as to partially overlap the collars 56and 74. Coins of the proper denomination are formed with a narrow raised rim inside of which the main body of the coin isthinner than the rim. 5
In Fig. 5 a coin is indicated at 109 and in Fig. 6 the coin-is shown in section andthe raised rim is indicated at 110, the showing being more or less schematic. While the collars 56 and Y74 engage the raisededge of the coin the collars 57 and 75,engag'e.the depressed faces of the coin inside the raised edge, the independence of the short shaft or roller 71 and a slight looseness ofits journals in the journal bearings permitting a corresponding portionfof the bifun;
cated end 96 of the spring'94 to move this roller where provided with the collar 75 closer to the collar 57 than the spacing of .the collars 56 and 74, while engaging the raised rim of the coin. Moreover, the roller 70 and the roller v55 are positively driven, but the roller 71 isnot driven directly at all. Consequently that portion of the coin engaging between the collars 56 and 74 is propelled downwardly, but the portion of the coin gripped between the collars 57. and 75 is not-correspondingly propelled, so'that the coin is discharged from between the collars 56 and 74 while still gripped between v the collars 57 and 75, wherefore it assumes a pendent position with relation to the collars 57 and 75. The center of the coin is under these circumstances substantially directly beneath the collars 57 and 75 and the coin has been swung with its center to that side of the apex of the nose 35 toward the chute continuation 49-, the position of the coin being indicated in dotted lines in Fig. 3. All this occurs while the operating lever is moving under the action'of the weight 81, and such movement of the lever continues until the tooth 88 comes into engagement with the angle :extension 92 of the finger 93, whereupon the rollers and 71 are moved away from the roller 55 and .the coin hanging between the collars 57 and is released and drops, so as to strike the apex of the nose 35 in asmanner to direct the coin into the chute section 49 from which the coin may travel to the structure depending upon the presence of the coin .the fraud preventing devices of the for its operation, such structure however not being shown in the drawing.
\Vhen a coin of proper denomination and condition is introduced into the machine and reaches the rollers, the co-llars 56 and 74 operate upon the rim of the coin inthe same manner as they do upona flat slug, but the collars 57 and 75 engage the depressed faces of thecoin within the rim, so as to still grip or retain the coin, after it escapes from the collars 56 and 74, and the coin gravitates to a pendent position and at the same time moves laterally into position to be directed into the portion of the coin chute leading to the devices to be coin operated. With all flat faced devices, such as slugs, or even a smooth coin which might reach the'roll'ers,
