'nonnnnn VENDING MACHINES, inc, A CORPORATION on new YORK GGIN-CONTROLLEDMECHANISM Application filed October 5, 1927. Serial No. 224,052..

trolled mechanism which is shown as embodied in a service-providing device of the kind employed for automatically efiectingthe sale of articles and which are commonly known as vending machines. The present invention may be considered in generalas a variant form of or modification of that invention by which it is adapted for rendering an entirely different form of service available. The coin controlled mechanism of the present invention asherei'nf disclosed is in control of a timedservice-supplying device,

for inaugurating the service to be supplied thereby and then, after a predetermined "period of time has elapsed, for discontinuing such service, so that therebythe service rendered available is provided only over a predetermined limited period of time. While the service-supplyingdevice shownherein as controlled by the present invention supplies electric current and while the embodiment of the invention disclosed herein is particularly adapted to be employed in connection with such device, it is to be understood as within the scope of the present inventionthatit may be employed, should occasion arise, in connection with and for controlling the operation of other forms of service supplying devices in which a substantially similar'manner ofoperation is required. I j, y

In carrying out this invention some of the features disclosed and claimed in my above noted prior application haK- G, been. retained in substantially similar'for-m, while other features havebeen changed and further features have been incorporated, so that, on the whole, a substantial departure has been made from this prior invention. It should be noted that the, construction of the coin carrier and its immediate adjuncts is substantially the same as in my copendin-g a plication for patent for vending machines, erialNo, 39,4l l2, filed 'June 1925, which becamalatent No.

In my application I 1,723,948, August -6,- 1929,011 which the magnet feature is claimed in my copending divisional application Serial No. 133,615, filed September'd, 1926, which became Patent No. 1,657,836,v January 31,1928.

. One object of the present invention is to provide a coin controlled mechanism which is particularly adapted for controlling the operation of a service-supplying device in such manner as first to initiate or inaugurate the available serviceand then, after a desired predetermined interval of time has elapsed, to discontinue the service thus provided, until another similar coin controlled operation.

is efiected, In this connection, another ob-' I ject of the invention is-to provide a coin controlled mechanismi which is I particularly adapted for heavy duty. Other objects are to provide a construction of this kind which is simple, strong, durable, effective, and inexpensive to manufacture Other objects and advantages of the invention will hereinafter appear. 4

The invention includes various featuresof construction and COIHbJIlfllBlOIlS' of parts,

which are set forth inthe appended claims,

and as will appear from the following de scription of one embodiment of the invention, which is illustrated in the accompanying drawings, in which: r

Fig. 3 is a partial vertical section substantially on the zig-zag line 3-3 of Fig.2, withsome parts omitted;

Fig. 4 is a partial verticalsection on the 7 line H of Fig. showing a detail feature of the construction;

F ig. 5 is a diagram of electric circuits,

and v "Fig. 6 is a reduced front elevation of the tem le; apparatus in which the. invention is embodied, with some of the interior parts shown in broken lines.

A vertically disposed main frame plate 1 of thecoin controlled mechanism is provided, on both the front and rear thereof, with various flanges, projections and bosses, as shown in Figs. 1 and 2, to provide supports and bearings for various operating parts of the coin controlled mechanism, as will hereinafter appear. A front frame plate 2 is disposed in parallel spaced relation to the lower portion of the main frame plate 1 and is firmly secured to forwardly projecting portions of the latter by means of screws 3 (Figs. 1 and 6). The main frame piece 1 is of substantially rectangular outline. andfits into a rectangular casing box 4 adjacent the top and left side thereof,where it is secured in place by screws 5 entering lugs 6 provided in the casing 4. A terminal block 7, of insulating material, is similarly secured in the upper right hand corner of the casing box t'by means of screws 8 and easing lugs 9.

A front vertically arranged baffle plate 10, curved inwardly at its lower end substantially flush with the lower end of the main plate 1, is secured to the adjacent right hand wall of'thecasing box 4 and serves to direct coins from the coin controlled mechanism into a money pan or coin box 11 which is loosely received in and substantially fills the bottonrpart of-the casings: below the main frame 1 (Figs. 1 and 2'). The casing box 4 is closed by a'fr'ont door 12 hinged to the top thereof at 13 and providedat the 'bottom with a suitable lock 11 (F igs. 2 and 6). The. door 12 is .cut out around'the major central portion of the front frame'plate2, which projects to the outside through the opening thus provided (Figs. 2 and 6-). The casing 1 may be conveniently mounted with 9 its back against the wall of a room and secured thereto in any suitable way.

A pair of line conductors or lead-in wires 15 and 16 may proceed from a'commercial supply service or from any suitable source of electric current,.in Fig. 5 the line conductor 16 being shown as grounded merely for clarity of illustration. Three conductive terminal strips, comprising a short terminal strip 17 and a pair of longerterminal strips 18 and 19, are mounted on, the insulating terminal block 7 The line wires 15 and 16 are connected respectively to the short terminal strip 17 and to the right hand longer terminal strip 19 by means of binding screws 20 and 21. The devices for utilizing the electric current are connected across the two longer terminal strips 18 and 19.

In thedrawings, the invention is shown as utilized commercially to "provide for. the

use of an electric hair curler 22. A pair of output or lead wires 23 and 24am connected to the curler 22. and twisted together to form an ordinary two-wire cord. One

of these leads 23 is connected to the lower terminal strip 18 by means of a binding screw 25 and the other lead 24 is connected to the other longer terminal strip 19 by means of a binding screw 26. Also, to furnish a light when needed in using the curler 22, a lamp 27 is provided, having leads 28 and 29 connected respectively to the two longer terminal strips 18 and 19 by means of binding screws 30 and 31. Obviously, instead of the hair curler 22 and the electric lamp 27, or in addition thereto if desired, electric current may be similarly supplied to any kind of electrically operated device, such, for example, as a suitable stove, an electric fan, or a radioreceiving set, merely by connecting' their. respective .lead wires across the two longer terminal strips 18 and 19.

For completing the circuit through the hair curler 22 and the lamp 27 to inaugurate the available service, and then, after a predetermined interval of time has'elapsed, for breaking the circuit to discontinue the service, an electrical connection is made between the short terminal strip 17 and the lower longer terminal strip 18, and this connection is subsequently broken. .Both of these results are accomplished by means of a suitable circuit making and circuit breaking switch which is operatedand controlled by the coin controlled mechanism. For this purpose, service completing conductors, shown as wires 32 and 33, are connected respectively to the terminal strips 17 and 18 by means of binding screws 34 and 35. The circuit wires 32 and 33 are connected respectively to switch terminals shown as binding screws" 36 and 37 (Figs..1 and .2) mounted upon the top of aswitchbox or casing 38 which contains the switch mechanism. A journal pin 39 in the lower part of the switch box provides a pivot for a service-controlling or switch operating lever 40 which projects below the switch box (Figs. 1, 2 and 5).

Any suitable form of switch may be em-' ployed and it maybe of astandard commercial type. In practice a readily purchasable well' known commercial type of single pole, toggle, snap switch having a single metal operating lever has proved satisfactory and that 'is the switch shown 7 in outside elevation in Figs. 1' and 2. In

View of the well known construction of.

switches of this type, it seems unnecessary to illustrate its internal construction. However, for a clear understanding of the manner of operation, a simple but operable conventional form of a' circuit making and breaking switch is shown diagrammatically in Fig. 5. As there shown, a contact member 41;,is connected by a con'ductor 42 with the binding screw 36 and a rocking switch arm 43 carried by the. rocking operating lever 10 has a pig-tail connection 44 to the other binding screw 37. In the position of insulating plate 4L5.

the switch operating lever shown in the drawings i-gs. 1 and the circuit is open and will be closed by the rocking of this lever 40 to its oppositely inclined position.

The switeh box38 is-supported on the front face of the outer portion of the main frame plate 1 with-the service-controllingoperating lever 40 projecting downward. The backof the switch boX 38 rests against an interposed The switch box 38 has a lower cover plate 46 which projects beyond its ends. A pairof L-shaped b-racketsorclips 47 are rivetedor otherwise secured to. the projecting ends of the cover'plate' 46 and are s e'- cured, by means or" a pair of screws48, to the frame plate 1. r g 1 1 This electric switch and-more particularly its operating lever 4:0, forms a part of the coin controlled mechanismyduring the operation of which this service-controllinglever 40 is operated in the manner required so as to be rocked to its current supplying position, and then subsequently, after the desired period of time has elapsed, to be returned to its normal position shown in the drawings, in which the supply of current is cut off. More broadly considered, however, the rocking service-controlling lever 40 .by which the requiredoperatingmovement is'transmitted to the current controlling parts of the switch, conceivably might be utilized for operating some other form or service-supplying f device, which might not be electric, but where a substantial- 1y similar manner of operation would be eiiective, should occasion arise for utilizing the present invention in connection with some such different service-supplying diavice, although the coin controlled mechanism of the present invention is "particularly adapted and intended for controlling a supply ofelectr'ic c'urrent,so as to render it available only over a predetermined limited period-of time. The features of construction provided in accordance with .the invention for thusoperat'ingthe service-controlling member, shown as the rocking switch-operating lever 40-, will now be described. 7

Suit-a'bly spaced rearwardly from the main frame plate 1, a rocking gear segment 49, which has substantially theform of an upwardly extending arm, is looselypivoted upon a rocking operating shaft 50which extends forwardly through the main frame platel and is journaled in a bearing 51 tor-med thereon, and which extends rearwardly and its rear end is iournaled' in a bearing block secured to the back wall of the casing This rocking arm 49 is normally disconnected from its operating shaft 50, and thereby formsan initial operating member for oper ating the rocking service controllinglever or switch operating lever' i0 which t-lru sforms a second operating member, for operating the above described electrical service-supplying device. For this purpose, the gear segment arm 49 near its endlcarries a pair of laterally spaced operating lugs or studs 53 and 54 which project forwardly throughan arcuate slot .55 in the mainframe plate 1. These studs .53 54 together with the ends of the slot 55 may serve as stop means for limiting the maximum extent of rocking movement of the gear segment 49, which is more particularly desirable in its return movement, as will presently more clearly appear. A pair of opposed operating screws 56 and 57 are respectively screwed transversely through the forward ends oif 'the respectivestuds 53 and 54 for transverse adjustment relatively thereto.

When the gear segment 49 is rocked forward and back the opposed spacedends of these operating screws 56 and .57 will engage alternately with the opposite sides of the rocking service-controlling lever 40 and thus I these screws, together with the studs 53 and 1 54 by which they are carried, form an adj ust able lost motionopera-ting connection between the gear segment 49 and the service-controlling'switch operating leverdO for rocking the latter, first to'its forward position and for r then returning it to its normal positionshown in the drawings. The operating armor gear segmental? thus forms an initial opera-ting member relatively to which the service-controllinglever 40 is a second operating memnli'sm.

It will be noted that as the gear segment arm -49 moves forwardly the service-controlling operating leverlG will not be rocked in her which directly operates the switch 'mecha-- its for-ward direction until the gear segment 49 approachest'he end oi its forward movement and takes up the lost motion provided between the end of the operating screw 56 and the operatinglever 40. Similarly, as the gear segment 49 is returned from its forward to its normal position shown in the drawings, the lost motion then present between the ends of the other operating screw 57 and the operating lever 40 will prevent the latter from beingreturned to its normal circuitopening position until the gear segment 49 approaches the end of its return movement. By suitably adjusting the operating screws 56 and 57, the extent ofthe lost motion between them as to each direction of their movement may be varied, for thereby rocking the circuit controlling switch lever 40 to the proper extent and at the proper point, in both the forward and. back rocking movement of the gear segnentt9: In a usual snap switch construction, as above'noted, when the movement of the. switch lever ,40 has been substantially initiated in one direction, it will be snapped over toitsopposite position by the switchmechanism, for thus quickly making or breakingthe electric circuit, which is desira ble, as is well understood.

The coin controlled means for manually rocking the initial operating member or gear segment arm 49 to its forward position, for thereby closing the electric circuit, will be described presently. ,An energy storing device is provided to be stored with energy by the gear segment 49 during its forward movement and then to become immediately effective for returning the gear segment to its normal position. Also a speed-retarding timing I so device is provided in connection with the energy storing device for retarding the return movement of the gear segment arm 49 over a predetermined interval of time, during which the supply of electric current is provided. The energy storing device and the timing device shown will now be described.

In the construction shown, a relatively small auxiliary frame is provided for the energy storing device and for the timing device which is shown as associated therewith. This frame has a front plate 58 and a rear plate 59 which are tied together by spacers 60, shown as three in number. This frame is supported at the rear of the upper portion of the vmain frame plate 1, and also at the rear of the upper end portion of the gear segment 49, by means ofthree small strips or clips 61, secured at the front face of the front plate 58 on the forward ends of the spacers 60 and having their projecting other ends secured, such as by means of screws 62, to rearwardly projecting portions or lugs formed onthe back of the main frame plate 1. V

- A main shaft 63, which forms both a spring-winding and a timing or retarding shaft, is journaled in the frame plates58'and 59 and projects forwardly, where at its forward end it is journaled in a bearing64 on the main frame plate 1 (Fig. 2). ,A springwinding pinion 65 is fixed on this shaft 63 and engages with the gear teeth of the operating arm or gear segment 49. A convolute ribbon spring 66, of the usual clock type, surrounds the shaft, 63, with its inner end connected thereto and with its outer end anchored to the spacer 60 at the top of the frame (Figs. 1, 2 and 3). The convolutions of the spring are arranged so that it will be wound up by the counter-clockwise rotation of the pinion 65, as viewed from the front (Figs. 1 and 3), this'being the direction of forward rotation of this pinion as imparted thereto by the forward rocking movement of the gear segment 49. \Vhen this spring has been thus wound, it acts through the pinion 65 asa return spring for the gear segment 49,

and becomes immediately eifective'for this purpose under the control ofthe speed-re tarding timing device, which will now be described.

An automatically actingone-way clutching connection is provided between the rotatable spring-winding and timing shaft 63 and the timing device, by which the timing device remains idle or inactive during the forward 67 is loosely mounted on the shaft 63 at the rear of the'spring 66 and forms a rotatable part of the timing or retarding device. Just at the back of this gear a clutch disc 68, shown as having a single clutch tooth, is fixed upon this shaft, with its clutch tooth directed backwardly in reference to the direction of forward rotation of the shaft. A one-way clutch pawl 69 is pivoted; by a pin 70, on the back of the gear 67, to be engaged by the tooth of the clutch disc 68 upon the reverse rotation of the shaft 63, while providing for the free forward rotation of the latter (Figs. 2 and 4). It will be noted of Fig. 4 that the gear wheel 67, which is located forwardly of the section line on Fig. 2, is accordingly shown in broken lines in Fig. 4. The clutch pawl 69 is urged towards the clutch disc 68 by a small leaf spring 71 attached to the gear wheel 67 (Figs. 2 and 4).

When the gear 67 is rotated by the shaft 63, through the flexing of the wound spring 66, this gear 67 transmits its rotation through a train of speed-multiplying, and correspondingly power-reducing, gearing shown as comprising consecutively, a pinion 72 fixed on a shaft 73," agear 7 4 fixed on this shaft and engaging a pinion 75 fixed on a shaft 76, a gear 77 fixed on this latter shaft and engaging a pinion 78 fixed on a shaft 79, and a gear 80 fixed onthe latter shaftand engaging a pinion 81 fixedona final shaft 82 The opposite ends of the. three shafts 73, 76 and 79 are journaledrespectively in the front and rear frameplates 58 and 59. The final shaft 82 is j ournaled at its front end in the front frame plate 58 and is also journaled in the rear frame plate 59 beyond which it projects. A ferrule 83 is fixed upon the rear projecting end of the shaft 82 and fixed upon this ferrule is a-fan or paddle 84. i

In accordance with well known principles, the air will offer a substantial resistance to the rapid rotation of this paddle fan, whereby, through the above described connections, the return to normal position of the switch operating arm or gear segment 49'will be retarded and delayed, so that the service-controlling operating lever 40 will not be returned thereby to its circuit breaking position until a predetermined limited period of time has elapsed.

insteadthereof, some other form of retarding device might be connected to the shaft 82, or

to a corresponding shaft orother rotatable part. For example, an escapement device substantially similar to those commonly employed in clockspsuitably constructed and adjusted to effect a proper timing, might be utilized for this. purpose. In fact, any suitable form ofretarding or timing'device'may be employed inconnection with the initial operating member or arm i9. A g

The clock type of spring. 66} shown has proved of particular utility as an. energy storing. device, in that it economizes space, is of light weight, and atthe same time provides for the storing of an effective amount of energy therein. However itissto be understood as within the province of the invention to employ some diiferentkind of suitableenergy storing device For example. a weight. might I beused for this purpose; Likewise, a. differ ent form: of springmightbeused andloperatively connected in a different manner to the initiaLoperat-ing. member or arm- 49.

v In. carrying out'the: invention, a counter or odometer is prov-ided' for indicating the number of operations of" the apparatus, and

* which consequently correspondingly indicates the number of coins which have been deposited in themoney pan 11. The indication of. the counter may be seen through a suitable window providedin the top of the casingil', this window comprising a slot in the casing covered at the i'nsidebya transparent plate 85, such as glass, heldin place a slotted shell86 securedby rivets 2') to the casing f. The counter per se may be ofa usual construction, as shown, and tl'ierefbre need not be described in detail. It issup ported in paitdirectly byt'he, main frame plate 1". at the top and. left side'tliereof and in part by aibracket plate87 secured'by screws 88 I) to a projecting portion of the main frame'pl'atei 1. The counter shown comprises three axially aligned number wheels 89 loosely mounted on a number wheel shaft 90, and apair of transfer pinions 91 loosely mounted on a pinion shaft 92. I v

The units wheel of the counter, which is the one at the r'ear and appearing at the right'in Fig. 2, is actuatedby avdriv'e pinion 93' loosely mounted on the pinion shaft 92 and havingconn'ected thereto a drive gear 94i The drive gearj94 is engaged and driven by a pinion- 95 which is formed'on or carried by large intermediate gear 96, both jjournaled" ona stud 97'. Ehis intermediate gear 96' is engaged and driven by the gear 87' to which the timing device is connected, 7 as above described. The above noted gearing, connecting'this gear wheel 67- with the? unit's wheel of the'number wheels89 is so proportioned that eaclitime the gear-wheel 67 is rotated the units number wheel will'be moved forward to the extent ofa' unit indication. This occurs, through the clutch connection 68" and 69., each. time that. the gear segment or operating arm. 4.91s returned from itsforward to itsfnormal position by the spring 66; 'Ihus each service-supplying operation of the apparatus will be indicated by the number wheels 89 of the counter. The; normally ineffective manually operable device coniprising the parts of thecoin controlled. mechanism which are made effective by neansof a proper coin, for'movin-g the initial operating member or gear segment arm 49- to its forward position, thereby: to inaugurate the'service supplied by the apparatus willv now be described, together with the various associated cooperating parts.

It will. be noted that the forward portion of the rocking operating shaft 50', which is journaled. in the bearing. 51 is of larger diameter than the: rear portion of this shaft upon which the combined operating. arm and spring-winding gear segment a9 is loosely mounted. Between the inner end of the bearing 51 and the front face of the gear segment 4:95 this shaft 50 is; shown as flattened on its opposite sides (Figs 1 and leverarmf98 is mounted on th-isfiattened portion of the shaft 50 to=.be rocked thereby and. normally extends towards the left at a slight inclination, as viewed. from the front (Fig. For obtaining adequate strength, with inexpensiveness of manufacture, this lever armis shown as made up 'offou-r plate parts secured togetherby rivets. (Figs. .2 and 3 This lever arm 98 forms a normally ineffective freely idly-movable driving member for the gear; segment armfrom which it is normally disconnected. A normally ineffective one-way coupling deviceto be made effective by a moving coin is providedv for coupling or connecting thelever arm 98'to V the gear segmentarm lll so t'liat this gear segment will then he driven bythe lever arm 98in the forward direction only of the rocking; movement ofthe latter. The particular coupling device shown asprovided for this purpose will now bejdescribed.

Above thero'cking operating shaft- 50 and parallel'theretoastar wheel shaft '99-is j'ournaled' in and projects through'ahearing 100 formed on themain frame plate 1 coindriven; star wheel 10.1 is fixed upon the front end of this shaft for rotating the latter. Theteeth of'thisst'arwheethaveabrupt faces in the counter-clockwise directionin which it is to be rotated, the othersides or' faces of these teeth being inclined. One of the teeth of this star whee1,.at the lower par-ti of its periphery ,5 is always normally positioned tobe engaged by the upper edge-portion of a moving coin'for thereby imparting a step of rotative movementtothe star wheeli second or rear star wheel 102, similar tothe first or front star wheel 101 and having the same number and kind of teeth correpondingl'y directedlis fixed upon the rear end of the shaft 99, and is shown (Figs. :1 and 3) as having its teeth positionedf midwaybe tweenthose of the front star wheel 101. This rear star wheel 102 is atvthe front of and adjacent to the upstanding gear segment arm .49.

' Both of the star wheels 101 and 102 are yieldably positioned and normally thus maintained by means of a yieldable stop device. For this purpose, in the construction shown, a stop roller 103 engages between the teeth of thefront or coin-driven star wheel 101, at the right thereof, as viewed from the front in Fig. 1. This roller is rotatable on a headed stud 104 which projects forwardly from the upper end of an upper arm of a bell-crank lever 105 the other arm of which projects towards the right, this lever being pivoted on a headed stud 106 which projects from the front of the main frame plate 1. The lower end of a coiled retractile spring 107 is'connected to the outer end of the lateral arm of this lever and the upper end of this spring is anchored to'the main frame plate 1 by means of a stud 108. This spring 107 urges the stop roller 103 towards the star wheel 101 and as this star wheel is rotated the inclined cam faces of its teeth will push back the stop roller 103 against the tension of the spring 107 which will react to position the star wheel and will be effective to impart the final portion of a step of movement there. to. Rotative movement of the first star wheel 101 imparts a like movement to the rear star wheel 102, which also is correspondingly positioned by the yieldable stop roller 103. A normally ineffective coupling member is 'inade effective by one of the teeth of the rotating rear star wheel 102 to form a one-way driving connection of the driving lever 98,

,in the forward movement of the latter, with the gear segment arm 49, thereby to impart forward rocking movement 'to the latter throughout the full extent of its operating movement, thereby to wind the spring 66 and to rock the service-controlling lever or switch operating'lever40 to the service-supplying or circuit closing position, whereby the service will be inaugurated in the manner hereinbefore described.

In the construction shown this coupling member comprises a two-armed substantially arcuate normally transversely extending pawl 109, shown as made up of two similar axially spaced parts which are rigidly connected together by two pins 110 and 111, of

which the pin 110 is at the right end, or end of the tail arm, of the pawl and the pin 111 is at an intermediate position in the en gaging arm of the pawl, which projects towards the left. Between these pins the coupling pawl 109 is pivoted on the gear segment arm 49 in notches provided in the top of a forwardly projecting lug or ear 112, on a pivot pin 113 which passes through this lug and through the body of the arm 49 (Figs. 2 and3). r

The engaging end of the driving arm of this pawl 109 is normally maintained above and out of the path of the end of the driving lever 98 in the rocking movement of the latter, by meansof a coiled retractile spring 114 which at its upper end is connected, between the two parts of this pawl 109, to the tail arm pin 110 and at its lower end is anchored to a pin or stud 115 which projects from the front of the gear segment arm 49. This spring 114 normally holds the driving arm of the coupling pawl 109 against a stop lug or stud 115 which projects from the front of the gear segment arm 49. The pin 111 which connects the two parts of the driving arm of the coupling pawl 109 is provided between these parts of the pawl with a roller 116 which, in the normalposition of the gear segment arm 49 and of the star wheels 101 and 102, is positioned just at the right of the inclined-face of'the end portion of the lowermost tooth of the rear star wheel 102 and substantially in contact therewith (Figs. 1 and 3.). t

As this star wheel 102 moves a step forward it will depress the driving arm of the coupling pawl 109 to bring its engaging end into the path of the end of the driving lever 98in the forward movement of the latter and willthus hold this pawl at its gear segment engaging position during the time that the" and is continuing to move while this star wheel is moving and depressing the engaging end of the coupling pawl 109, as will presently clearly appear, some free space or lost motion is provided between the endof the driving lever98 and the engaging end of the coupling pawl 109 in the normal position of this driving lever and gear segment arm 49, as clearly appears in Fig. 3. At the time when this lost motion is taken up, the engaging end of the coupling pawl 109 will be held down by the end of the tooth of the star wheel 102 which isthen in engagement with the pawl roller 116.

Soon after the end of the driving lever 98 magma Z driving lever 98 isnotched as shown (Fig 3.) to provide thereon an undercut'driving face 117 at an acute angle to the radius of this lever and the engaging end of. the coupling pawl 109 is correspondingly pointed'at an acute angle complementary to this driving face. As the gear segment'arm 49 is rocked forwardly by the driving'lever 98, through the intermediary of the engaged coupling pawl 109, the gear segment arm carries with it thecoupling pawl and moves thela-tter bodily away from the rear'star wheel 102.

At this time-the moving coin, together with the spring-pressed stop roller 1-03,'willhave repositioned the star wheels101 and 102'.

The construction of the coupling pawl 109 to operate inthe manner just described forms one of the features provided for, assuring that the apparatus shall be in a nonoperable condition until thegear segment arm 4.9 has returned to its normal position tocomplete a service-supplying operation which has been inaugurated, as will hereinafter clearly appear; j

The manually, operable means provided in carrying out the invention for rocking the driving lever 98" in the forward direction and for concomitantly moving the coin to impart a step of'rotative movementto the star wheels 1'01 and 102 will now be described together with the ancillary features controlling the operation of the coin controlled mechanism and thus of the service-supplying operation.

Near the top of its exposedcentral portion the front frame plate 2 has through it a slight ly inclined coin slot 118. A normally ineffective freely idly movable rocking coin carrier 119 is fixed-upon the forward end of the operating shaft 50, so that thereby the driving lever 98 and the coin carrier 119 are positively and rigidly connected" together for concomitant unitary rocking movement. At

its front the coin' carrier 119 is provided witha pivot stud 120 (Figs. 1, 2 and 6') whic h is journaled in the front plate 2 in axial alignment with the operating shaft'50'. The coin carrier 119 extends above and below its pivotal axis and is of substantlally arcuat'e segmental shape towards the leftfas viewed from the front in Fig. 1.

The arcuate periphery of the coin carrier 119 at the left of its axisis provided with a limiting lug 121 which may move between lower and upper stop lugs 122 and 123 provided on the main frame plate 1' for limiting the rocking movement of the coin carrier 119 and of the driving lever 98. At its top the coin carrie'r119 is provided with a coin holdin g slot- 12 l and outwardly from this slot it carries a coin'movingfinger 125 to engage with substantially the center of the left side of a coin 126 ('(Fig. 1) the lower edge of which is seated in the slot 124.. This finger 125 wtll pass through the hole of a vaslier and cause it to be discarded. The C0111 holding slot 124 is normally in alignment with the'lower portion of the coinv slot 118 in the front plate 2' with the end of the finger 125 just at the left of'the latter slot. The right hand inclined face of the upper stop lug 123 is substantially in alignment with and just clear of the upper part of thercoin slot 118' andservesas a guide and support for the inserted coin 126.. i y

A laterally curved horseshoe magnet 127 is pivoted at 128 in a notch provided in thetop of the lower stop lug 122, where it is held in place by a screw pin1 29. The upper spaced pole ends of the magnets arms extend at an upward inclination towards the-right above 9 and beyond the upper stop lug 123 and normally slightly overlap the upper portion of i the coin slot 118. The magnet arms-are yieldingly pressed against the stop lug 12, which is notched to receive them (Figs. 1 and 2) by a spri-ng130 which is carried by the magnet by means of a pair of lower andupper pins 131 and 132 witli: the u per end of this spring engaging against a lug 133 provided on the frame plate 1.

When a proper coin is pushed through the coin'slot 118 its upper edge will engage the forward'mhgnet arm to lift the ends of the magnet andhas the coin passes inwardly it will be received at its upper edge betweenthe spring-pressed magnet arms which will position= the coin so that its forward edge will be" clear ofthe coin slot 118- in the-front plate 2 when the coin is moved away from this slot by the rocking of the coin carrier 119, so that 3100 gage and release the rollers 134 and1 35 thereby causing a paramagnetic slug to be-discarded by the coin carrier 119 coacting with the magnet'127.

A transversely extending coiled retract-ile return'spring 137 for the driving lever 98 and the coin carrier 119 is anchored atone end to the end of a pin 138 secured in a forwardly projecting portion of the main frame plate 1 atthe'lower right hand corner thereof. The other end of the spring 137 is connectedto the lower end 'of'the coin carrier 119' through the intermediary of a bent or curved lever 139 located for the most part in a deep slot 140 in the right hand and lower portion of the coin carrier and pivoted to the lower end of the coin carrier by a pin 141. The return spring 137 is connected to thelever 139 below its pivot pin 141;, so that thereby the upper sides thereof, by means of a pin 142, a pair of reversible pawls 143, one of which appears in Fig. 1. These pawls are, urged towards their intermediary position (Fig. 1) by a corresponding pair of small coiled'retractile springs 144 connectedto tails of the pawls and anchored to the pivot pin 141 of the feeler lever 139. An arcuate saw-tooth ratchet 145, shown as secured to the front of the main frame plate 1, is provided for the'pawls 143.

When the coin carrier 119 is rocked substantially to its full extent the pawls 143, in both the forward and the return movements of the coin carrier, will wipe over the ratchet 145 and escape from the corresponding end thereof. In an idle movement of the coin carrier, when there is no coin in its slot 124, the pawls 143 may reverse on the ratchet 145 to permit the return of the driving lever 98 and the coin carrier 119 to their normal position, the upper end of the feeler lever 139 then passing across the empty coin holding slot 124 as these pawls reverse. A coin in the slot 124 will prevent the reversal of the pawls 143 on the ratchet 145, thereby compelling a full forward movement of the driving lever 98 and the coin carrier 119 before they can be returned to their normal position. This prevents the loss of coins in the apparatus.

In this connection, however, it should be noted that after the coin carrier 119 has begun its return movement the pawls 143during their return movement on the ratchet 145, will be locked against reversal, so that thereby the coin carrier 119 cannot be again moved forward from a partially returned position, but is compelled to complete its return movement for the escape of these pawls from the lower end of the ratchet 145. This locking against forward movement of the coin carrier 119 results by reason of the locking toggle formed by the pawls 143 with the lower arm of the lever 139 between the pawl pivot 142 and the pivot 141 for the lever 139'on the coin carrier 119.

This locking of the coin carrier 119, by the pawls 143, against forward movement from a partially returned or intermediate position will likewise similarly lock the driving lever 98 against forward movement. This locking of the driving lever 98 has particular utility in the carrying out of the invention as one of the features in the means provided to prevent a second, orsuccessive, service-supplying operation from being inaugurated before the first has been completed, as will presently clearly appear. It might be furthernotedin this connection that when the operating arm or gear segment 49 is coupled to the driving lever 98, as above described, the extent of forward movement imparted to this operating arm 49 by the driving lever 98 will be determined by the upper stop lug l23-for the coin carrier 119. o

In view of the fact that the freely movable driving lever 98 and coin carrier 119, after having been rocked to their forward service providing position following the insertion of a coin, willbe immediately started on their return movement by the coin carrier spring 137, while the operating arm or gear segment 49 will be returned slowly to its normal position while the service is provided, it will be realized that unless some preventive means were provided, the driving lever 98 could be again rocked forward, either from a partially returned or from its fully returned position, a successive number of times, thereby again to rock forward the operating arm 49 from a partially returned position thereof and thus prolong the service rendered indefinitely without the insertion of any more than a single coin.

Obviously also it is desirable, as a vsafeguard to the customer after a coin has been inserted,-that assurance of a complete service-supplying operation of the apparatus shall be provided. For this purpose, means are provided to prevent the apparatus from being restored to an operable condition until the gear segment arm 49, in its retarded movement, has fully returned to its normal position for discontinuing the service which has been paid for. Accordingly, in carrying out the invention, means are provided to prevent the return of the coin carrier 119 to its normal coin-receiving position until the gear segment 49 hasv completed its retarded return movement to its normal position.

In the construction shown, 'a three-armed stop pawl 146 for the driving arm 98 in its return movement is pivoted on a headed stud 147 which projects from a rear thickened portion of the main frame plate 1 (Figs. 1, 2 and 3). This stop pawl has an upstanding engaging arm, a tail arm projecting to the right and a releasing arm projecting to the left, as seen from the front in Figs. 1 and 3. This pawl is urged to rock irra clockwise direction, as viewed from the front (Figs. 1 and 3), by a coiled retractile spring 148 connected at its upper end to the end of the tail arm of the pawl and at its lower end anchored, by means of a screw 149, to a rearwardly projecting portion of the main frame plate 1. This pawl148 is stopped in its spring-actuated movement by the abut ting of its tail arm againsta stop lug 150 which projects from the back of the frame plate 1.

.tained by the operating screw 151 in the normal position of the gear segment arm 49 (Figs. 1 and 3), The driving lever 98, together with the coin carrier 119,-thus may be rocked idly forward aindback throughout'the extent of'their movaaeneerto a less extent, without the driving lever 98having any engagement either with thecoupling pawl 109 orthe stop pawl 146. p

When the gear segment arm 49 is moved forward by the driving lever 98, following the insertion of a coin, it-will lift the operating screw 15 1 away from the releasing'arm of the pawl 1'46 and the pawl spring '148 will then beeoine eifecti ve'to move the stop end of this pawl into thetterminal portion of the return path of the driving lever 98. WVhen the driving lever 98 and the gear segment arm 49 have completed their forward movement, the coin carrier spring 137 becomes immediately etteetive for quickly returning the driving lever 98 and the coin carrier tow ards their normal position, while the gear segment arm 49 is returning slowly. To wards the endof such return movement of the driving lever 98 the lower side ofits outer end will abut/against the stop end of the pawl 146, therebyarresting the return movement and preventing the full return of the coin-carrier 119 to its normal'coin 1 8-"- ceiving position, whereby the coin controlled mechanism will be 1n a non-operable condition. During the terminal-part of the re tarded return movement of the gear segment arm 49, after the desired fpredete'rmined interval of timehas elapsed, the operating'screw 151 will come into engagementfwiththere leasing armofthepawl 146 and as the gear segment 'arn '49 completes its return movement it will rock the pawl 146 back to its normal position, out. of engagement with the driving lever 98, whereupon the coin carrier spring "137 will complete the'returnmovement of'th-e driving lever-98 and coincarrier 119, so that the latter wlll'be returned to its normal coin-receiving position and the coin controlledmec'hanism will thusloe inan operable condition for a subsequent operation of. the entireappara'tus. It will be noted of the particula'r construction shown and as'already described'th'at'the cooperating relation existing betweenthe stop pawl l46"and the coincarrier pawls 143 is without the insertion of a'coin.

effective to lock thedrivinglever 98 against forward movement while it is in engagement with the stoppawl 146, by reason of the fact that the coincarrier pawls 143 cannot then reverse on -the ratchet 145 to'permit such forward movement. This prevents the gear segment arm 49 from being rockedforward from some intermediate position of its retarded return movement, and thus prolongthe service indefinitely following the insertion of a single coin.

It will also be noted ofthe particular construction shown that as soon as the 'driving lever 98begins its rapid return movement it will release the coupling pawl 109 which then will be immediately. snapped by its spring'114to its uncoupling ordisengaging position at a timewhen the gear segment arm 49 is'a-tits forward position and isonly beginning its retarded return "movement. The coupling pawl "109 will thus be at an ineifective position throughout the return inovement of the'gear segment arm- 49, sothat forward movement of the driving lever 98 could be permitted and would then be ineffective to drive the gear segment, as thedriving lever 98 could rock idly beneath the inefiective coupling pawl 109 at time during'the retarded return movement of the gearkseg ment arm 49, as well as after-it has returned to its normal position. Thusthis-coupling pawl construction in itself wouldbe'eife'ctiveto prevent the prolongation ofthe service It therefore becomes evident that, in the particular embodiment of the invention shown, either one orgthe other of these fea tures for preventing undue prolongation of the service beyond thetime paid fOrmight be retained and theother omitted. Consequently, the particular construction shown has the advantage that itprovides latitude for suitable modification in construction, which might bedesirable in some instances, For example, a slight modification of the feeler lever 139 in relation to its pawls 143 would permit the driving lever 98 and coin carrier 119to be moved forward from an intermediate position of their return niovement, in which case the particular pawl'eonstructionshown would prevent the driving forward of thegear'segment arm 49, Also it is'conceivable'that some entirely different device other than the feeler lever 139 and its pawls 143 might be employed for preventing the loss of coins in the apparatus. Also the construction of the coupling pawl 109 may be changed in such manner that this pawl would then retain its eiiective or engaging position'throug'hout the majer portion of the return movement of the'gea'r seg-f ment arm 49, and would then be moved to its ineffective position as the gear segment arm approaches the termination of its return movement to normal position. In such case, the locked pawls 143 would be effective to prevent forward movement of the driving lever 98. Also in case the stop pawl 146 should be omitted and, for example, some difierent device employed for rendering the coin controlled mechanism inoperable, then the particular coupling pawl construction shown would permit the idle and inefiective rocking of the driving lever 98 to a forward position during the retarded return movement ofthe gear segment arm 49.

While the coupling pawl construction shown is particularly intended and designed to be employed in a coin controlled mechanism for a service-supplying device, such as shown, in which the service provided is extended over a period of time, it is to be noted that this construction of coupling pawl is also suitable to be employed in a different construction of the coin controlled mechanism for a different purpose, such, for example, as that disclosed in my above noted application for patent Serial No. 224,051 filed October 5, 1927, which is there shown as employed to operate a vending machine. This other application discloses the above noted different form of the coupling pawl,

.which as above noted, might be employed in carrying out the present invention.

'At the completion of the forward movement of the coin carrier 119 when it carries a coin 126, as shown in Fig. 1, the coin may drop upon an inclined ledge 153 provided on the forward face of the main frame plate 1, from which it will slide and drop upon the lower inwardly turned end portion of the baffle plate 10 and thence into the money pan 11. A coin disengaging or kick-off pawl 15% is provided to assure the disengagement of of the coin from the coin carrier. This pawl is privoted at the front of a thickened portion of the frame plate 1 on a pin 155 and nor mally rests on the top of the magnet spring lug 133, against which it is pressed by a bent wire spring 156. This pawl extends over the coin carrier 119 and has its free end inclined downwardly, to be lifted by the advancing coin and upon the return movement of the coin carrier to engage and dislodge the coin.

The manually operable means shown as provided in carrying out the invention for imparting forward rocking movement to the driving lever 98 and the coin carrier 119 against the tension of their return spring 137 will now be described. Within a large slotted opening in the coin carrier 119 there is provided on the coin carrier an internally toothed arcuate rack 157. A shaft 158 passes through this opening and is j ournaled at its ends in the frame plates 1 and 2. A pinion 159 fixed on the shaft 158 engages the coin carrier rack 157 and at its forward end has connected thereto a spur gear 160 at the front of the coin carrier 119. The gear 160 is engaged by a similar gear 161 which is rotatable on a headed journal stud 162 projecting inwardly from the front plate .2. These gears 160 and 161 are contained in a recess formed in the inner face of the front frame plate 2, as shown in Fig. 2. In view of the fact that en by a tubular pinion 163. The rear end of this pinion 163 is smooth and is journaled in a bearing 164 formed on the front of the main frame plate 1, through which the end of this pinion extends. The forward end of this pinion has thereon a head 165 which is journaled in the front frame plate 2 in a bearing 166 forming a front boss on this frame plate; A handle knob 167 has its hub 168 journaled in the outer end of the bearing boss 166 and is fixed upon the outer end of a handle shaft 169 which extends inwardly loosely through the pinion 163 and projects some distance beyond the rear end thereof. A clutch element 17 0, journaled within the bearing boss 166, is connected to the hub 168 of the handle knob 167 to be positively rotated in either direction by the latter. The pinion head 165 forms a cooperating clutch element with this handle-driven clutch element 170. These clutch elements 165 and 170 are shown (Fig. 2) as provided with complementary inclined interengaging clutch teeth so as to form a oneway driving clutch of the ratchet type.

The inwardly projection portion of the handle shaft 169 carries a coiled compression spring 171 which acts between the handle shaft 169 and the inner end of the handle pinion 163 for maintaining a positively acting one-way driving connection between the clutch elements 165 and 170. The forward end of this clutch spring 171 bears against a washer 172 which bears against the inner end of the pinion 163. The inner end of this clutch spring bears against a nut 173 screwed on the inner end of the handle shaft 169 and by which the tension of this spring may be adjusted. The inclined clutch teeth of the clutch elements 165 and 170 are shown (Fig. 2) as disposed or directed so that clockwise rotation of the handle knob 167 (Fig. 6) will positively drive the pinion 163, while rotation of the handle knob 167 in the opposite direction will cause the handle-connected clutch element 17 0 to yield and rotate on the pinion clutch element 165, thereby apprising the customer that the handle knob 167 is being rotated in the wrong direction.

When the handle knob 167 is rotated in the forward or clockwise direction, the driving lever 98 and the coin carrier 119 will be posi tively rocked in the forward direction against the tension of their spring 137, through the intermediary of the above described driving connections comprising the clutch elements 165 and 17 0 and the power-multiplying toothed gearing, beginning with the pinion 163 and ending with the coin carrier 157. \Vhen the coin carrier 119 carries a coin the operating arm or gear segment 49 will then also correspondingly be rocked to its forward position, to inaugurate the service by which, in the construction shown, a'supply 0- electric current becomes available, and at the same time during this forward movement of the gear segment 49 to wind the spring 66, which after the predetermined period of time, under the control of the speed-retarding timing device, as above described, will discontinue the service which has been provided.

lVhile the gear segment arm 49 is being thus rocked forward the handle knob 167 may, if desired, be released at any time to obtain a fresh grip thereon, or it may be rotated alternately forward and back without releasing the grip of the hand thereon, in either case the engaged coin carrier pawls 143 then preventing reverse or return movement of the gear segment arm 49, driving lever 98 and coin carrier 119 from their partially advanced position, thus maintaining them and permitting their forward movement only, as has been already described.

The operation of the coin controlled mechanism shown has been already for the most part described, and will now be summarized. When the coin carrier 119 carries no coin, it

= and the driving lever 98 may be freely idly rocked to their forward position or to any intermediate position and then will be idly returned to normal position by the coin carrier spring 137. In the construction shown, the limited forward movement of the driving lever 98 and the coin carrier 119 will be completed with about one complete rotation of the handle knob 167. \Vhen the coin carrier 119 carries a coin, as shown in Fig. 1, the forward rocking movement of the coin carrier 119 will at first idly move the coin 126 beyond or out of alignment with the coin slot 118in the front plate 2, and at this time the pawls 143 will become engaged with the ratchet 14 5 to prevent return movement of the coin carrier 119, driving lever 98 and operating arm 49.

As the coin carrier advances, the coin will immediately engage the adjacent lower tooth of the coin-driven front star wheel 101, which it now rotates, together with the rear star wheel 102. As the coin thus moves it lifts and passes beyond the end of the kick-ofi pawl 154. The rotating rear star wheel 102 immediately depresses the engaging end of the coupling pawl 109 against the tension of its spring 114. WVhile the coupling pawl 109 is maintained in this position by the rotating rear star wheel 102, the forwardly rocking driving lever 98, having taken up the intervening lost motion, is brought into'engagement with the end of the coupling pawl 109, and thus drives the gear segment arm 49 in its forward rocking movement. While the star wheels 101 and 102 are being driven forward by the moving coin, the coupling pawl 109, in its engaged condition, is carried bodily away from the rear star wheel 102 as the gear segment arm 49 is rocked forwardly by the driving lever 98. In the initial portion of its forward movement the gear segment arm 49 releases the stop pawl 146.

As the gear segment 49 is driven forward by the driving lever 98 it rotates the pinion 65, thereby, through the pinion shaft 63, to wind the spring 66. In the construction showmjust following the completion of a rotation of the shaft- 63, it carries the clutch tooth of the retarding clutch disc 68 beyond the end of the spring-pressed pawl 69 of'the gear wheel 67, preparatory to engagement with this pawl for operating the timing device having the air paddle 84 and the counter having the number wheels 89. As the forwardly driven gear segment arm 49 approaches the termination of its forward movement, its left hand operating screw 53 comes into engagement with the service controlling operating lever 40 and rocks the latter to close the electric switch, which is shown conventionally in Fig. 5 as the switch arm 43 and contact member 41. The customer will be apprised of the comple-' tion of this part of the operation by the coin carrier 119 reaching the limit of its forward movement, whereby the engaged driv-y ing clutch elements 165 and 170 will stop the further forward rotation of the handle knob 167. The power-multiplying gearing driving connecton makes the winding of the spring 66 easy. I

When the handle knob 167 is released at the completion of its forward driving movement, the coin carrier spring 137 immediately re turns the driving lever 98 and the coin carrier 119 to the point where the driving lever 98 abuts against the stop pawl 146. Immediately upon the beginning of this return movement of the driving lever 98 it releases the i coupling pawl 109, whereupon this pawl is immediately snapped to its disengaging position by its'spring 114. The gear segment 49, now having been set free, is slowly rocked backwardly'and is finally returned to its normal position by the reversely rotating pinion 65, which is now driven by the unwinding of the spring 66, through the shaft 63. As this shaft 63 is thus rotated reversely it carries with it the gear 67 by reason of the engagement of the tooth of the clutch disc 68 with its pawl 69, whereby the air paddle 84 opposes, the spring 66 and delays the return of the gear segment 49 to its final normal position over the desired predetermined period of time, which. in the particular construction shown willbe in the neighborhood of ten minutes. During this period of time While the gear segment arm 49 is returning, electric current will be supplied for heating the hair curler 22 and for lighting the electric lamp 27.

As the gear segment arm 49 approaches the limit of its retarded return movementits right hand operating screw 57 will come into engagement with the service-controlling operating lever 40 and will rock this lever in the opposite direction, which will operate the switehto open the'eleetrie circuit. Also as the gear segment arm 49 approaches the limit of its return movement, its pawl-operating screw 151 will come into engagement with the stop pawl 146 and release the latter from its engagement with the driving lever 98, whereupon the coin carrier spring 137 will immediately snap the coin carrier 119 back to its normalcoin-receiving position relatively to the coin slot 118 in the front plate 2. This,

together with the extinguishing of the lamp 27,Will apprise the customer that the current has been cut off and that the apparatus is now in condition for a seubsequent operation by the insertion of another coin. The completion of the operation will be indicated by the number wheels 89, through the gear connection by which they are driven from the gear 67 as the latter is rotated by the spring 66. The illustrated embodiment of the inven- .tion has operated successfully and satisfactorily in use. It is obvious, however, that various modifications may be made in the construction shown in the drawings and above particularly described, within the principle and scope of the invention as defined in the appended claims.
