E p DONNELLAN `STOP MECHANISM FOR COIN COUNTIG MACHINES s'roP MECHANISM FOR COIN COUNTING MACHINES Filed June l2. 1931 2 Sheets-Sheet 2 Patented June 2l, 1932 UNITED STATES PATENT OFFICE EDWARD Il?.` DONNELLAN, OF BROOKLYN, NEW YORK, ASSIGNOR 'IYLO STANDRDJOHN- SON COMPANY, INC., OF-BROOKLYN, NEW YORK, A CORPORATION OF NEW YORK STOP MECHANISM FOR COIN COUN'IING MACHINES Appncation sied June 12,

com supplyingl or feeding means, whereby` the coin feeding operationis immediately discontinued upon completion of the count `of a `predetermined numberof coins of'any given denomination.

`More particularly, this invention provides 'novel means to positively lock the counting register actuatingmechanism whenthe last of a predetermined number of coins has 'passed the star wheel of said actuating mechanism, andsaid positive lock means includes a setting slide' bar Vwhich is tripped by the counting register'actuatin'g mechanism for spring actuated forward movement'to engage in a notched wheel forming part ofthe latte'rvmechanism so as to positively arrest vfurther movement of saidmechanism. AFurl-thermore, said slide bar, when released, ac-

tuates power clutch releasing means whereby actuating power for the machine is cut off, and said clutch releasing' means includes a detent mechanism which independently holds and locks the same in clutch releasing'position until the slide bar is fully reset to normal .initial'position This-invention has for-"a further object to provide novel means for shifting the clutch releasing means relative: to the slidebar and fdetent'mechanism-to arrange thel machine for continuous counting operations when ldesired.

Other. 'objects of this invention, not, at this '1931. semina. 543,793.

time more particularly enumerated, will be understood from the following detailed description of the same.

An illustrative embodiment fof this invention is shown in the accompanying drawings, in which Fig. 1 is a fragmentary plan view of a coin counting machine, showing the counting registeractuating'mechanism and the novel automatic clutch releasing means lfor arresting operation of the machine-and positively locking the register actuating mechanism against move-ment, partsv being broken away to disclose underlyingV mechanism.

F ig, 8 is a fragmentary transverse vertical section, taken on line 8-8 in Fig. 1.

Similar characters of reference `are employed in the above -describe'dviews, to indicate corresponding parts.

Referring to the drawings, the reference character 10 indica-testhe framework ofa .(not here shown) which .forms part oflthe machine substantially in the vmanner disclosed in my aforesaid copending *application for Letters Patent Ser. No. 408,187, filed November 19, 1929, and which is driven from lit) IFA

a source of power, such as an electric motor, by transmission mechanism including a suitable releasable clutch means, as also disclosed in my said copending application, but illustration of which is not essential to an understanding of the present invention.

Journaled in the framework 10, to extend along the rear side of said back-plate 11, is a shaft 12 which is also driven from the clutch controlled power transmission of the machine. Fixed on said shaft 12 are primary coin propelling rolls 13, there being one such roll for each chute-like passage, and consequently for each denomination of coin handled bythe machine. Said backplate11'is suitably cut away to permit the.

peripheries of the rolls 13 to intersect said chute-like passages. Also journaled in the framework 10, to extend along the forward side of said back-plate 11, is a shaft 1li upon which are fixed secondary coin propelling rolls 15, the peripheries of which engage the peripheries of said primary rolls 13.

Said back-plate 11, in conjunction with the framework 10, bounds a housing 16 which contains the counting registers 17 and` actuating mechanisms therefor; there being one register for each denomination of coin.

Fixed within the housing 16 is a transverse bearing plate 18, forwardly spaced from and parallel to said back-plate 11. Journaled to extend forwardly from saidbaclrplate 11 through said bearing plate 18 are register actuating shafts 19, which are resaectivel dis osed ad'acernt to the sets of l y P l primary and secondary coin propelling rolls 13-15. Fixed on each shaft 1 9, to lie in the path of movement of coins downwardly propelled by the adjacent set of coin propelling rolls, is a star-wheel 20. A similar sta.rwheel 21 is fixed on each shaft 19 at the .rear side of said bearingrplate 18, and cooperating with each of these star-wheels 21 is a suitable yieldable detent-pawl 22 to prevent overthrow of the shafts 19 when actuated by coins pr pelled into operative engagement with star-wheels 2O by the rolls 13-15. Said star-wheels 2O each possess five points so that shafts 19 will each complete a full revolution on actuating engagement of the star-wheels by five successive coins.

Fixed on each shaft 19 is ,the driving mem ber 23 of a Geneva gearing, the driven member 24 of which is rotatably mounted on a stud shaft projecting from said bea-ring plate 18. The Geneva gearings for the different countingaegisters differ in ratio according to the predetermined number of coins of a given denomination desired to be counted as a lot; all in the manner clearly disclosed in my aforesaid copending application for Letters Patent Ser. No. 408,187, filed Noven'iber 19th, 1929. Fixed in connection with each driven member 24 of the Geneva lgearings, so as to rotate therewith, is a trip cam and a. notched lock wheel 26, the purposes of which will presently appear.

Arranged within said housing 16, beneath the registers 17, is a frame member 27 including a front plat-e 28 and a depending rear f flange 29. Connected with the latter is a latch-bar 30. Movable through said front plate 28 are slide bars 31 corresponding in number to the number of counting registers and actuating means therefor. Each slide bar 31 is arranged for forward sliding movement under the urge of spring means 32. Toward their rearward ends, each slide bar is provided with a latch-nosing which engages with said latch-bar 30 to normally retain the slide-bar in inwardly moved position. At its rearward end, each slide bar is further provided with an upwardly projecting combined trip and lock lug 34; which, when the slide-bar occupies its normal inwardly moved position, is rearwardly odset out of register with a corresponding notched lock-wheel 26 but' engages vthe periphery of the associated trip cam 25. The rearward end of each Yslide bar 31 is yieldably uplifted by spring means 3.5 to normally engage its latch-nosing 33 with said latch-bar 30. Each slide bar 31 is provided intermediate its ends with an upstanding push-lug 36, the purpose of which will be hereafterl explained.

VSuitably ournaled within the housing 16, to extend across land above said slide bars 31, is a rock-shaft 37. Transversely slidable through the housing 16, adjacent to one end of said rock-shaft 37., is a clutch control bar 38, which is actuated in inward direction lby a pull-spring 39 to actuate a. clutch (not shown) operate to couple the machine transmission mechanism with the source of driving power, but which when moved in outward direction operates to release said clutch. Fixed on said rock-shaft 37 is a forked lever arm 40 Ywhich engages a laterally projecting stud 41 carried by said clutch control bar 38, whereby the latter is operatively connected with said rock-shaft.

Fixed on said rock-shaft 37, adjacent to each slide-bar 31, are rocker plates l2, the same having laterally projecting studs 43, which extend across adjacent slide-bars 31 to lie in front of the push-lugs 36 thereof. Each rocker plate is provided at one side with a stop-arm 14 adapted to engage the frame member. 27 to limit the movement of the rocker plate, and consequently the rock-shaft 37, in one direction. Each rocker plate is further provided, on lits opposite side with a peripheral notch 45 engageable by the hereinafter described detent mechanism.

Pivotally supported from bearing brackets 116, which are secured to the underside of said frame'member 27, are detent levers 47, which respectively lie adjacent to the rearward sides of the rocker plates 42. Said de- 25 "leverand beneath the'lift cam' portion 53 of 48, engageable at proper times with the pe iripheral"notch'es 45 'off said rocker plates 42.

Connected with each slide'lbarlSl is'a laterally'projectingl lock lever control stud which lies'forward of the thrustslroulder 54' of an adjacent lool:

I`the latter. 'Theexteriorly projecting forward end of eaclisl'idebar' 31 is providedwith a suitably 'formed 'finger or push-piece 56 to aid in tlie lmanual 'A operation of the same at proper The rock-shaft 37 is so mounted in its supporting bearings as to becap'able of a limited 'longitudinal`v shafting movement, A'wherebylthe -sainemay' be so moved at will, `asto laterally displace the rocker plates 42 aiidtheir studs 43 from'operative relation to adjacent s lidelbars 31, whereby tripping ofv t'lie'latter w'i'll'not actuate the rock shaft to "move the clutch controlbar'38 to clutch releasing position,whfen it is desired that the tra y'machine shall continuously count coins,

vvrz'ither vthancount the same in lots of predetermined number.

The 'means for manually'shifting the'iock-shaft37 and its rocker `plates ,4l-2teY in service`or 'out of service posi- `ti ni`5as`the case may be, comprises a suitably 'Tjournaled'cross'shaft 57,`having a forward exteriorly projecting end equippedv with' a "finger-"piece" |57y for actuating the saine (see 'Figi 'Secured'ltoy said cross 'shaft'57 is a vleverarin'58 provided with a stud 59 which 'engage'slin an "annularly channeled collar 60 carrie/d by said rock-shaft 37. By turning sai'dvcross shaft 57 to the left, said lever arm :58is swung to the left to longitudinally shift :said'rocl' Lshaft'37 and its rocker-plates to out of service position; and,`vice versa, by turning'said crossshaft'to the right, said rockshaft and its rockerplate's are brought fpbacjktoin service position. The"operation of the mechanisms, when arrangedto'count coins in lots of predetermined number, is as follows:

The slide bars 3l are all pushed inwardly, against the'tension oftheir springs 32, until their latch-nosings 33 are Eengaged in'V restrained relation by thelatchbar 30,andtheir lock lugs 34 underlie the tripcains 25, klallas shown in Fig. 2'of the drawings. Then said? slide bars occupy suchfpositions, "the clutch control bar 38 is held by thesp'ring 39 in position to'retain the clutcli'ineans of the machine power transmission operative to transmit actuating power to the coin counting macliinell The machine now funotions'to assort and feed coins tothe several counting register actuating means'according to their denominations, whereby the coins pass to the'c'oin propelling rolls l3--15, which grip and impel the same in passing engagement with they star wheels 20. As each coin engages inpassing contact with a Vstar wheel'20, itf produces a rotative impulse of the latter, each such impulse bewith actuating effect upon the counting registers 17. The rotations of the shaftsflQ are in turn transmitted tothe Geneva'gearing 23-24 for producing Vrotative movement of Ying transmitted Ythrough the shafts 19y to and saidv trip cams 25 and notched lock "wheels" 26, to thereby produce completed revolutions of the same when a predetermined number of coins of a given denomination have passed and'actuated a corresponding star wheel 20 i and arsociated counting` register. Preferably@ the trip cams 25'are' set slightly in advance of the associated notched lock wheels 26, so thatthey trip the slide bars 3l controlled thereby just before the last coin is counted,

whereby the lock lug 34 of a tripped slide' bar is arrested by an arm of the notched lock ii'liecl 26, Figs. 3 and 4), thus depressing the rear end 4of said slide bar to'disengage its nosing33 from the restraint of the latch bar 30, so that as actuation by the last coin en# sues, the notch of the lock wheel 26 will Ibe moved in'to registration with the lock lug 34, to completely release theaffected slidebar 31 for forward sliding movement under the pull of its spring 32, whereby the lock lug A34 is* moved into the notch of said lock wheell 26,

thus positively preventing further rotative i movement thereof,'and consequently positively locking the register actuating means associa-ted therewith vagainst further move-A ment (see Figs. 5 and 6)'.

l/Vhen the desired predetermined'number of cot-iis of any given denomination has been counted, resulting in the release, forward sliding movement and locking effect of a slide' bar 3l, as above described; the forward movement of the latter carries its push-lug36 into thrusting engagement with the stud 43 of an associated rocker plate 42, whereby said rocker plate is swung forward, until stopped by" engagement of its stop-arm 44 with the frame member 27. This swinging movement of the rocker plate 42 rocks the rock .37,ffto swing the lever arm 40 so as to pull outwardk y. the clutch control bar 38, to thereby throw las out the clutch of the machine power' transmission means with resultant immediate stoppage of the machine.

The forward swinging movement of the rocker plate 42 positions peripheral notch 45 opposite the catch-nosing 48 of the adjacent detent lever 47. During the forward sliding movement of the slide-bar 31, the stud 55 thereon is carried forwardly into engagement with lift cam portion 53 of the lock-lever 50, whereby the forward end of the latter is lifted to release its stop-lug 5l from normal abutment against the front plate 28, thus freeingV the lock-lever 50 for forward movement, and thereby releasing the detent lever 47 for movement, under the urge of its spring 49, toward the rocker plate 42. This movement of the detent lever 47 carries its catch-nosing 48 into holding engagement with the peripheral notch of the rocker-plate 42, thereby positively locking the same, and thereby also retaining the rock-shaft 37 and clutch control bar 38 in the clutch releasing position to which it has been moved (see Fig. 5), such conditions being maintained until the slide bar 31 is re-set to normal latched position, and whereby accidental or premature throwing in of the clutch and restarting of the machine is avoided until latched condition of the re-set slide bar is assured.

To re-set the slide-bar 31, the operator presses inwardly on its push-piece 56, thereby thrusting inward the slide-bar 31 so that its latch-nosing 33 is snapped over the latchbar 30. This inward movement of the slidebar 31, does not disturb the detain-ed condition of the rocker plate 42 as maintained by the detent lever 47, but merely carries inwardly and away from the stud 43 the pushlug 36. while relocating the latch-nosing 33 behind the latch-bar 30, at the same time removing the lock lug 34 from the notched lock wheel 26 and repositioning the same beneath the trip cam 25. The described inward movement of said slide bar 31 also carries the stud 55 away from the lift cam portions 53 of the lock-lever to a position ready to engage the thrust shoulder 54 of the latter (see Fig. 7).

By the above described operations, return of the slide bar 31 'to normal locked position has been assured before any possibility of releasing the clutch control bar 38 for clutch engaging operation. To release the clutch control bar 38 for clutch engaging operation,

thepoperator continues inward thrust upon the slide bar 31, to produce a limited` inward movement of the same slightly beyond its normal locked position. This additional movement carries the stud 55 into inwardly pushing engagement with the thrust shoulder 54. of the lock-lever 50, whereby the latter is moved inwardly until its stop-lug 51 falls into stopped abutment upon the front wall 28 under the downward pressure of spring 52. This inward movement of the lock-lever 50 swings back the detent lever 47, thereby removing the catch-nosing '48 from detaining engagement with the peripheral notch 45 of the rocker plate 42. lThe rocker plate 42 being thus freed, the spring 39 will slide inward the clutch control bar 38 to clutch actuatingv position, thus again subjecting the machine to power driven operation.

This spring actuated movement of said clutch control bar also operates through lever arm 4t) to return the rock-shaft 37 and its rocker plates 42 to normal initial position, ready for a repetition of the above-described operations as soon as the count of another lot of coins of any denomination is completed.

While I have described the mechanism as arranged to count coins of several different denominations', it will be understood that it may be arranged to count either a single or two or more diiferent denominations as may be desired.

As many changes could be made in the above described constructions and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that Yall matter contained in the above description 0r shown in the accompanying drawings shall be interpreted as illustrative and not in alimiting sense.
