Specification of Letters Patent.

Application led March 11, 1911. Serial No. $13,723.v

varying as to certain dimensions, but which' shall at the same time refuse to accept coins whose dimensions are intermediate of, as well as greater or less than, those of the coins which it is designed 'to accept. I also desire toprovide improved mechanism for actuating the bodily movable portion of a coin vselector of the above noted general type; the invention also contemplating novel means for lessening the amount ofwork necessary for operating' the device.

Another object of my invention' is to provide a coin selector so deslgned as to receive coins varying in thicknesses while havf,

ing certain other characteristics'in common but which shall discard coins having intermediate thicknesses lacking in the above noted common characteristics'. v

These objects and other advantageous ends I secure as hereinaftenfset forth, reference being had to the accompanying drawings, in. which Figure 1, .is a side elevation of a coin selector constructed according t'o thfe present invention;'- Fig. 2, is an end elevation of the machine shownin Fig. 1; Figs. 3 and 4 are. sections taken on the linea-dt, Fig.

14' and illustrating certain, ofthea parts carried thereby; Figs. 16 to 19 inclusive are sections on the lines 0: -`a., bei), owe, and JZ-d, Fig. 14,'and Figs. 20 to 22 inclusive are fragmentar sections on a greatly Aen larged scale an `with certain of their parts considerably exaggeratedns to their proportions, illustrating certain features oftheconstructionand operation of my device.

` In the above drawings 1 represents a supporting structure whiclrin the 'presentiii-- stance is shown as aportion of a 'box having two compartments as and y into which the good and bad coins respectivelyfare to be delivered. Carried by this structure is `a vertically extending Xed plate 2. having' mounted in 'it a pair ofl horizontallyprojecting bolts 3 on which is yieldingly carried a casing 4 containing one ofA the two. 'sets of com controlled valve operating` mechanism.

A second casing 5 containingA a second similar set of mechanism is 'slidably mounted on the bolts 3 so as to be movable toward and from the' casing t, and for the purpose of causing such movement I provide an. operating handle 6 mounted onv a s indle 7 which is supported in suitable formed in lugs projecting from-the front `face of the plate 2. Fixed. to this'spindle 7 by means of a setscrew 8 is a cam 9 carrying an anti-friction roller 10 so placed as to be capable of' engagement with one ace of a' vertically slidable block 11 guided in a suitable recess in the rear face of the plate 2, as shown in Fig. 7. The detail construction of said block is well illustrated in Fig. 10 from which it will be seen that it is Hat on its rear face while its opposite `facehas iat the top a curved projectingportion 11, below which is arelatively deep notch or recess. A spring 12 acts fon the upper portion of this block 11 to insure its returning to its lower position after it has been moved therefrom. f

p '85 earings In addition to the cam 9 the spindle 7 car-4 i ably formed guide on the plate structure 2.

The upper part of this same'rck bar is providee with a second ,ser of aaa` is 15mg-iii 19 a plane substantially at right angles to the Y teeth and so placed as to engage the teeth of a toothed wheel or segment 17.

This lat- Y ter is fixed to a plate 18 and has formed integral with it in the present instance, a pair of projecting lugs 19 and 2 0 there being a hole throughit for the reception of the end part of a cam shaft 21. This' shaft is reV- olubly mounted in the casting of which the plate 2 forms a part and projects rearwardly for a purposehereafter noted; there being fixed on its end adjacentl the toothed segment 17 a disk 22 having a pair of facial projections 23 and 24. 1n addition there is a spiral or other suitable spring 25 mounted on the shaft 21and having a projecting end 26 lying adjacent one face of the disk 22 so as yto be capable of engagement by the pro-4 jection 19 of the toothed segment 17.

In a suitable recess of the plate 2 is mounted a'locking plunger 27 having an end 280i reduceddiameter pressed toward thedisk 22l by a spring 29 and capable of entering an opening in the projection 24 on the disk.22 so as to lock this latter with the cam shaft 2,1. The plunger 27 is so mounted that it is engagedv by the upper portion of the vcam 9 when the spindle 7 Iisv sulicientlly turned and is moved thereby rearwar y into its cavity'so as to draw its reduced portion 28 out of the opening 30, thereby unlocking the disk 22 and leaving it free to be turned. A screw 21 threaded into l the'end ofthe slide-governing or cam shaft plate structure 2 upon which the casing 5 is" designed to slide. This latter has rigidly fixed to.l it a front cover plate 35 serving to confinein place a vertically movable `slide36 whch,' .as shown in Fig. 5 is normally PriSSed downward by means of a spring 37 and has near its upper portion an opening through whichl extends the cam shaft 21.y

-Extendingthrough one side` of the slide 36 is a somewhat elongated holey or slot for the reception of a pin 38 threaded into the cover plate 35 and extending through the yeo various piecesoarried by the casings 5 andA 4. Thispin terminates within the latter in lposition tocoperate with one end of a lockyrngtjnnbler 39, and the slide has within `1t'a.. epring pressed lookin tumbler 40 whose Raman l t j operate with a second pin; 4T threaded into y projecting en is designed,to,.co-4

force the tumblers 39 and 40 into their rece'sses in the slide 36 and 43 as to no longer exercise any action which would prevent these latter being moved downwardly by their respective springs 37 and 44. The

'slide 36 is normally pressed toward the rear of the casting 5 not only by the spring acting on the tumbler 40, but also by reason of the action of a number of other springs re# spectively acting on locking tumblers 45 to 54, tending to cause them to project rearwardly.4 These Various tumblers copcrate with a number of pins, shown in detail in Fig. 12, which are carried by a flanged ring 55, a cylindrical block 56 within the same, and a-cover plate 57 fitted to the front or flanged end of said ring; being held in posi tion by screws 58. The block 56 has adjustably threaded into its front face a pair of studs 59 which project through the plate 57 and coperate with the two pins 47 and 53. Said block which is provided with a rear peripherally extending knife edge, has an axially extending opening for a pin 60 which extends through the plate 57 and cooperates with the tumbler 52. On either side of this central pin are two pins 61 and 62- so placed as to respectively coperate with the tuniblers 4-8 and 51. As shown best in Fig. 17, this block 56 is normally forced forward by a pair or springsb but is prevented from moving rearwardly more than a predetermined distance bymeans of a stud 64 threaded into an opening 65 in its cylindrical surface and projecting through an Iopening 66' in the side of the lianged ring 55 ;-the outer portion of this stud being reduced in diameter to permit of a slight Yrelative movement of the same and hence of the cylinder/to which it is attached. As is obvious this stud not only limits the longitudinalmovement of the block but prevents -its rotation.

Mounted in the casing 5 immediately abovethe opening -into which the flanged ring 55 projects, is a pin 67 whose position is such that under operating conditions it comes into engagement with the rim of a coin. A locking tumbler 46 is so mounted as to coperatewith-said pin.

1t is to be 4understood that the pins 61, 62, and 67 forexample, are headed so as to be incapable of falling out of their cavities under the action of the springs which bear up[on their coperatinglockin tumblers.4` n addition to these, I rovi e four pinsh68, 69, 70, and 71. herea ter referred to more in. detail, mounted in cavities er tending through the main annular part ot the flanged ring 55 and lyingat substantially thesame distance from thef axis or center line of said part.

As clearly shown'in Fig. 12, the pins 69 and 70, While being of the same construction, are dilerentin form from the pins (i8 and 71 though all four of them co-perate with four-.locking tumblers A45, 49, 50 and 54. The tivo pins 68 and 71 have veach a relatively large diameter body portion tapered at an angleof about 45 to a'small diameter end portion 72, while their opposite ends zare abruptly reduced to .a second small diameter portion. The pins 69 and 70 on the .other hand, as best shown in Fig. 18, have central or" body portions which while being abruptly reduced to small diameter parts' at'one end, arerovided adjacent their rear ends with annu ar recesses. Each recess While having one of its walls substantially atright angles tothe axial line of the pin, has its other wall tapered at about an angle of 45, it being noted that the pin .68 is so mounted in the flanged ring as to be diametrically opposite the pin- 71 to '25 which it is similar.

As shown in Figs. 5 and 6, the ring 55 has its flanged vface recessed for the reception of a plate 73 and as illustrated in Fig. 15, this' latter has two vertical slideways 3o .in which are mounted a pair of elongated steel plates 74 and 75 so laced that the pins 69 and 71 pass throng opposite ends of the plate 74 while the pins 68 and 70 pass throu h the ends of the plate 74. Said plates are ree to slide for a limited distance in their supporting plate 73 and their function is to prevent, under predetermined' conditions, such a 'rearward movement ot' certain of the pins as will move their cop- 40 erating tumblers into the positions which would release the slide 36. With this idea in view, the plate 7 4 has a uniformly cylindrical hole in its lower portion of exactly the same diameter as the body portion of the pin G9. The other hole in this plate, however, is counter sunk as shown, for the reception of the pin 71, so that when. said pin is suiiiciently moved, its beveled surface may coperatie with the counter-sunk surfaceof said hole to move the plate 74 upwardly. Similarly, while the upper hole of the plate 75 is of exactly the same diam` .eter as the body of the pin 70 and is, of unifrom bore throughout, the lower hole in said platev is beloved and counter-bored so that `when the pin 68 is properly moved, it likewise may cause vertical movement ot said plate by reason of the action of its beveled surface. It is obvious that as long as any portion of the cylindrical body of the pin 69 lies Within the lower hole of theA plate 74,'

the pin 71. cannot-.bc moved lon ritudinally beyond a 'certain point, since sai plate lies in the way and t e. 'pin 69 locks it against GQ the movement which would bring lits hole'in ,slide 36.

line with said pin 71. If, however, the pin 69 be moved to bring its tapered surface or-its reduced diameter portion into the plane of the plate, then thc latter lnay be raised by lthe pin 71 which -rnay then Vbe 70 moved longitudinally to its. full extent.,

Aside from the fact that the holes in the' plate 75are reversed in their positions, this latter exercises a similar locking action on one of its pins, for as long as the cylindrical body portion ofthe pin 70 lies within the upper hole of saidplate 75, the pin (5S cannot more to the rear but a relatively shortdistance which, as in the ease ot'lthe pin 71,

is not suiiicient to bring its coiij'ierating tuni- 80 hier tothe position necessary to release the inasmuch as thc mechanism contained within the casing -l and its associated parts is .practically identical with that hitherto described as contained Within the casing 5, it will not be referred -t-o in detail, except that it may 'be noted that its various pins and tuinblers, etc., are so proportioned as to release the slide only when there is pre- 90 sented to said pins a Acertain one of the tivo faces of a standard coin.

Similarly the mechanism ci the casing 5 is so setand arranged as to cause the tumblers to be moved to their releasing positions lonly when the same face of a standard coin -is presented to them as thatwhich releases the slide looking-mechanism of the casing 4.

As best shown in Fig. 8, the cam shaft '21 is cut away where it passesthrough the slides 3C and 43 so that when in'one position, these latter may drop to their extreme lower positions but will thereafter be raised by the cam action of this shaft when the' latter is turned under the action ofthe mech- '105 anism previously described.

Mounted on the casing 4 is a coin chute 7 (3 so placed as to direct a coin to be tested into a position between it and the casing 5, where it .is supported inthe proper position partly`by means .of a' stud 77 projecting rearwardly from one side of the' casing 5 and partly by anelongated rod 78 which. extends through a suitable slot inthe slide 3G and openings inthe cover plate 35, the 115 plate structure 2 and the casing 5, so as to project to the rear of the f ianged ring 55.

As shown in Fig. 7,-thc'rear end of this rod 78 is cut away so as to render it more or less iexible and its front end is provided 12o with a downwardly projecting arm-79 having a pin-80 extending into a slot 81 in an arm 82 fixed to the operating shaft 7. The arrangement and proportioning of these parts in such that the operating handlev 6 125 may be moved back almost to the limits of its possible movement before the pin 8O is operativelyengaged and thereafter the final so` as to vdisengage the coin which may have .been supported by it.

The slide 36 has at' its lowerend a laterall 4 ro'ectin armf83 engaging a projec-v tioii liroiln a cgciin directing valve 84 which is normally pressed into engagement with saidvprojection by means of a spring 85. On the opposite side of this valve is a second `arm engaged by one arm of a level:l 86 whose second arm extends under the slide' 43 so as to' beactuated thereby.- The valve 84 is mounted directly under the space between the two casings 4 and 5 so as to receive a coin falling from said space and is mounted on trunnion screws 87 in the well known manner.` When in its normal'- position said Valve is so placed as to' deliver a coin into the bad coin compartment of the receptacle beneath it and when de ect ed, as by a downward movement of elther of the slides 36 or 43,'it delivers into the compartment a: which is or standard coins.

In order to prevent more than one coin being acted on by the mechanism above describ'ed there is 'provided a longitudinally movable rod' 88 made wedge shaped at its `rear end as indicated at'd and at' its -orward end engaged by thefcam 9. on the operating-.shaftf. As a resultthe -irst move-Y ment of said shaft and cam occurring when Ithe handle 6 isopcrated, moves to the rear .this rod-88 and interposes its wedge shaped end between a coin whichmay be supported between the two casings 4 and 5 upon i t e. members 77 and 78, 4and a second coin which may have been introduced into the coin chute 76. Inasmuch as this rod4 con- .tinues in its projectedI position under the.

outlet l(rt-the coin chute until the operating handle with its attached parts returns to' the normal position, there is no possibil' ity ot' a second coin being allowed to pass downwardlyv into position between the two -casings 4 `andl 5 and their associated parts f the coin chute 78, it will roll ldown said chute and finally come to rest upon 'the two rods 77 and 78 vbetween the casings '4 and 5. The rearward movement of the operating handle 6, through'` the shaft 7 will then' turn the cam 9 so as to bring the roller 'l0y carried thereby intoengagement lwith the 1,042,9eef

projecting curved surface 11 of the sliding ltherear and forces with it the cover p ate 35 and the casing 5 attached thereto with" their associated parts. ',At the same time therod 88/s projected immediately above the coin supported as above noted so as to prevent any additional coins `interferingwith the proper operation of the machine, and the lturning of the shaft 7 through' .the

'block 11. This is therefore moved bodil to i' toothed segment`13 also moves upwardly the rack 14 through the teeth 15. The second set of teeth16 on said rack, beingin engagement with the teeth J,of the segment the locking end28 of the plunger 27 being projected intothe hole 30 of the disk 32.

If vit be-assumed thatthe two sets of mech- -anism carried by-the casings 4 and 5 are both adjusted to rel-ease their slides when, the head of a standard coin is presented toy them and if it be further assumed thatl the coin be so introduced into the machine that its head side is turned toward thecasing 5, then the various pins 60, 61, 62, 68, 69,' 70, 7l, and 67 will all be brought into engagement with various parts of said part of the coin as the said casing-is moved tovward the same,A as will also the knife edges of the cylindrical block 56 and of the flanged ring. 55. As a result, these pins will force their various tumblerstoward the slide 36, as 'will also the two pins 59 carried by the block 56 and thepin4l carried by the casting 4, Awith the result that under the conditions noted, the plane of engagement of the various tumblers with their coperating pins will fall between the plane of the rear face' of the slide 36 and that of the front face of the plate 73. Said slide is thus unsupported except by the canilh ft1 21 and as the operating handle 6 is mol to its extreme rear position, the upper l of the cam' 9 finally comes into en Y igement with the plungen 27, moving this to the rear against the action of the spring 29. When the reduced end 28 of this plunger finally releases t-he disk 22, this latter 1n- I stant-ly'turns under the action ofthe spring 25 and also turns thecam 'shaft 2 1 into such position that its flat ornent away part is uppermost, thereby leaving-theslide 36 l altogether unsupported so thatfit is immediately forced down under the combined action of gravity and of the spying 37. At the same time the valve 84 is turned on is sup porting pivots or trunnions-b reason of the y fact that its 'projecting portion is engagedl by the arm 83 of said slide', so that the outy 30. 10 first raises the block'll to t let of said valve is directed' toward the ppeninginto the compartment w within the oase. l

lust before the completion of`4 the rearward movement of the operating handle 6 the roller l0 passes belowthe highest part of the curved portion 11*t of the block 11 and the casing 5,"which has previously been moved toward the casing 4 and its associated parts as faros was permitted by the coin, is thusieftiree' to return to its koriginal position under the c't'm'ihinedv action ofthe various springs associated with it.v At the same time the lastrfearward movement of the operating handle, through the operating shaft 7 andthe arm 82, moves forwardly the rod 78 throughthezpin 80 and the arm 79,

thereby leaving the ooinunsupported and causing it to be guided by the coin chute in 2a its fall into thecom'partment zu. Under the conditions assumed the second slide/13 is not released or unlocked since the tail face of the coin was presentedto the pins'which govern the tumblers coperating with said slide;v

The release of the operating handle pen .mits the operatingshaft and the cam' 9, with their associated parts, to return to their normal positions and in so doling the roller leiupp'er portion of its guidewayaga'instrthe-action of the spring 12 and.thereaf terdisengaging it, permits it to' return to the normal position shown in Fig. 5;

Sii

cycle ofoperationA occurringwhenl a standard coin is introduced in a definite position into the. machindm 'will no-w proceed to describefmore in detail the operation of cer- 4c tain parts of thexdevice upon which in a f largemeasure defnds its accuracy and certaintyl of operation in separating certain predetermined standard coins from other standard coins of different nationalities but ,4.15 of the same ,or similar dimensions except in 'most' minute particulars.

`'lin-Wigs. 20 to 22 inclusive, Iy have shownl on a greatly enlarged scale the parts to which l have reference and in order that 5o' the features referred tomay be lperceptible, I. have to some extent exaggerated certain of their yproportions,` for it is to be understood that the dimensions upon whose dif-k ference! depends the acceptance or rejection 5&5 o/a coin by my machine are measuredin one-thousandths of .an inch. In the par ticular figures I' have' illustrated on an en larged scale the parts shown by the section a-a, Fig. 14, and .in designing the instru- V citt ment, it is to be understood that the pin 7l in the case of a ycertain instrument, is so made as to be two-tliousandths of an inch longer than thepin 69 .immediately under it and also' passing through the same'vertically movable, plate 7d, 'so that under the action while i have above roughly described the of the spring behind the tumbler it projects by the above noted amount beyond. the plane which includes the adjacent end of the pin 69 and likewise beyond the knife edge of the cylindrical block 56 whichl normally is in the lsame plane as said second pin.

The vertically movable plate 74 is nor mally in its lower position. and the pin 69 is. o'f such proportions that a portion of its body enters the lower hole of said plate so as to ordinarily lock it in such osition. The pin 71. 'is` of such length and tli are so arranged that as long as the locking late is `in this osition said .pin cannot e pushed back su ciently to bring the plane e parts of contact between its end and the tumbler y 4.5 into the space between the plate 57 and the slide 36. In other words in order to release the slide 86 itis necessary, in addition to moving back the in 71 a certain predetermined'distance, t at the pin 69 bealso 0 \moved backl not only far enough to release the locking slide 74, but also for a .distance sfuicient to bring the plane of contact o its end with the tumbler 49, into the s' ace betweenV the plate 57 and the s de 36.-

For example, if a coin be presented' to these two pins which is of the dimensions and nationality the instrumentl is designed to receive, its central head will project two,- thousandths of an inch beyond the-surface ofwhatis known as its root andthe pins 71 and 69 are so placed that while-.one of 1 them engages this-raised head, the other will lnecessarily engage th depressed root' or.

4tion adjacent thereto. It may be'note in passing that the design of themachine is `such that the other pins 70 and 68 will likewise engage one with the root portion and the' other withthe head portion of the standard coin.

' If the first of the two .possible conditions contact with the root surface o the coin.

If, as in the case assumed, the root is twothousndths of an inch below the level ,pf

the. surface of the head, then the body of the pin 69 is moved out of the lowerhole in the slide 74- just as the beveled portion of the pin71 engages the beveled'portion of the upper hole in'said plate,.sothat the latter is unlocked arid'bothpins are free to be moved 4longitudinaily to the rear suliiciently to free the slide 36 as above described, when the coin finally comes to rest against the knife edge of the flanged ring 55. The various' iso partsthen occupy the positions shown in F ig. 21.

It, however, the' root portion of the coin should be o posite the pm 71and the head part be in ine with the pin '69, then with the above described proportionin' and dimensions, both pins would simu taneously be engaged byV said coin, and it is obvious that' the pin 69 would be well out of the plate 74', thus :freeing the same, before the pin 71 was so far pushed in as to have any interference with its movement.

Under these circumstancesy the various parts would/occupy the positions shown in Fig'. 22 when the coin had been pushed to the maximum extent toward the flanged sleeve 55. It, however, the difference in level Vbetween thehead andy root of the coin is more or less than two-thousandths of an inch, thetumblers L15 and 19 would not be .moved under any .conditions to their released positions since the engagement of the head with .the pin 71 would either fail to move it suiliciently to they rear, orwould tend to so move it before the pin 69 unlocked the plate 74:, with the result that said tumblers 45 and 49 couldnot be moved to the posit-ions necessary to unlock the slide 36.

Under another condition the pin 69 might be moved to-unlock the plate 74, but unless the above noted partsof the coin wereproportioned as above noted, Athe pin 71 would not be moved far enough toproperly actuate the tumbler 45. In one case for which my invent-ion was `particularly adapted, the machine was `designed to accept any one of three issues of standard coins, whose thickness however, differed very widely, although the distance from the root to the head was substantially lthe same in each instance as were valso certain other dimensions of parts engaged by the others ofv the pins shown in the drawings. t v, l l

lt was necessary, however, that the machine shouldnot accept standard coins o another nationality whose thickness was intermediate those of the diderent -issues of standard coins, and this 'end was yattained by the use ofthe above described selective mechanism ,fit having `been found that these coins of other nationalitiesA differed from the standard coins as to the distance between the levels of their heads and roots'.

By providing means whereby the various slides are positively supported by the cam shaft 21 until all of thepins have moved their tumblers into what will be slide releasing positions if the C oin is an acceptable standard, I am enabled to employ springs of much lighter tension than hitherto, withoutin any way interfering. with the certainty of c operation of the machine.

It will, moreover, beV seen that as a con-l sequence of this construction, much less force is required than hitherto for the operation of the handle 6. As tending to assist in-produing thisl desirable result, I have provided the peculiar cam construction shown in Fig. 1 at 9 and have employed the roller 10 for transmitting movement' from this cam to the slide member 11.

. As is well-understood by those acquainted with machines of' the class to which my invention belongs, those other pins whose operation has not been described in detail are so placed as to engage the various parts of the coins presented to the machine and are designed to so coperate with their tumblers as to move these to their slide releasing positions only when a predetermined face of certain standard coins is engaged.

As clearly shownin Figs. 20 to 2:2 as well as in others of they drawin s, each ofthe two slides 36 and 4.3 is space an appreciable distance away from the adjacent face of the plate 57, thus making provision for a certain amount of variation in the dimensions of the coins acted upon; the machine thus being capable of accepting 4standard coins which have been worn to a certain extent and also standard coins which vary in their dimensions owing to the fact that, they belong to different issues. With this allowance for variation in dimensions it .was found, however, that coins of other nationalities would be received as long as their .dimensions were within the predetermined limits, but with the peculiar mechanism including the pins 68, 69, 70 and 71 and their associated parte it was found possible to make a, machine so that it would refuse this objectionable class of coins.

As is obvious upon the' release of the operating handle G, the casing 4: with its at tached parts is drawn back to the normal position shown in the figures by means of springs 96 acting between the plate structure 2 andathe heads of screws 95 which pass through said structure and enter the front plateattached to said casing.
