COIN-CONTROLLED FAN.

Application filed November 19, 1924. Serial No. 750,755.

, This invention relates to motor-operated fans of the coin-controlled type, designed mainly for use in refreshment parlors and similar places Where customers, in warm weather, may desire to purchase the additional4 comfort-of an artificial breeze.

The general object of the invention is to provide a simple, inexpensive and entirely automatic device of the character specified whereby a customer, by depositing a coin in the device, may obtain the operation of the fan for a limited period. Other objects are to provide a device of this character wherein vthe fan will have a bodily rotating move- `ment so as to distribute the breeze radially Vin a circle, to 4provide a device which will automatically Vstart in operation upon the deposit of the coin and will operate and automatically stop at` the end of a predetermined period, and to provide a device wherein a single electric motor will both ro- .tate the fan on its own axis and also swing or turn the fan bodily ,in a circular path.

Other objects and attendant advantages of the invention will be apparent to persons familiar with the art from the following detailed description, taken in connection with the accompanying drawings wherein I have illustratedinv structural detail an apparatus well adapted to fulfill the stated purposes and objects -of the invention and embody the i principle thereof, and in which-w Fig. 1 is an elevational view of the complete apparatus;

F ig. 2 is a vertical section of the parts below the motor and fan;

Fig. 3 is an enlarged cross-section looking downwardly on the line 3-3 of Fig. 2;

Fig. 4 is an enlarged cross-section looking upwardly on the line 4 4 of Fig. 2;

Fig. 5 is a vertical transverse section on the Aline 5-5 of Fig. 4;

Fig. 6 is a vertical section on the line 6 6 of Fig. 4; and

Fig. 7 is an enlarged vertical cross-section on the line 7-7 of Fig. 4.

Referring to the drawings, 10 designates a base plate on which is secured, by screws 11, a circular sheet-metal housing 12. To the top of the housing 12 is secured, by screws 13, a circular plate or disc 14 formed with an upstanding annular flange 15 overlapping and extending somewhat above the upper edge of the housing 12. Secured to the top ofthe disc 14 is a smaller disc 16, in

the center of which is secured a collar 17 forming, with the

discs

16 and 14, a bearing and support for the lower end` of a central vertical stationary shaft 18. A 19 designates a circular sheet-metal casing of a diameter to fit loosely vat ,its lower end within the flange 15 and having secured in its upper end, as by screws 21, a conical cap or cover 22. Attached to and depending from the top of the cap 22 is a long sleeve 23 having an extendedbearing on the shaft 18 and at its lower end attached by a'flanged collar 24 to a disc 25 fittedV Within the lower end of the housing 19.` Encircling the lcollar 17 and resting upon and attached t0 the disc 16 by screws 26 (Fig. 3) vis a stationary spur gear 27 made of insulating material. i

Mounted upon the upper end of the cap 22 is an electric motor 28 operatinga directdriven fan 29. The motor 28 at its rear end is geared to and drives a vertical'shaft31 ythat extends through an opening ,32.in the cap 22 and is journaled at its lower end in a bearing 33 attached to the under side of the disc 25. Keyed on the lower end of the shaft 31 is a spur pinion 34 meshing with the fixed gear 27. Manifestly, the rotation of the shaft 31 by the motor 28, operating through the pinion 34 and fixed gear 27, causes a rotation on the fixed shaft 18 ofthe housing 19, cap 22- motor 28 and fan 29.

Current is supplied to the motoras follows. Referring to Figs. 1 and 2, in the lower portion of the housing 12 is mounted an electric coupling 35 for the circuit wires 36 and 37. From the inner end of the coupling 35 a wire 38 extends to a binding post 39 (Fig. 4) on one side of the bifurcated stationary member 41 of an ordinary snap switch that is mounted on the under side of a bracket 42 attached to the bottom of the plate 14. From the other sideof the stationaryswitchmember 4 1 a `wire 44 leads from a binding post 43 to a binding post 45 that, as shown in Fig. 7, extends through an insulation block 46 on the-lower side of the plate 14, the upper plate 16, and the fixed gear 27 being encircled by an insulating sleeve 47. The upper end of the post 45 passes through and is rivetedI into a countersunk hole in a ring 48 (Fig. 3) of good conducting material, such as copper, seated in an annular groove in the face of the gear 27. Attached to the under side of the plate 25 by an insulated binding post indicated at 49 in Fig. 3 is a depending brush 51 which wipes over the ring 48. From' the binding post 49 a wire 52 leads into the motor. The other wire 53 (Fig. 2)

from the coupling 35 leadsvtothelower ,side

of a binding post 45 similar inall respects to the binding post 45 and mounted` in other end of the block 46. The upper end ot the binding post 45 isrivetedintoa smaller ring 54 (1* ig. 3) mountedin a vgroove in the upper face of the' gear 27 concentric with the outer ring 48. A^brushr55 attached -to` the lower 4side of the lplate' 25 by an insulated binding post 49 similar to-tlie'b-inding post 49, sweeps fover the inner ring 54. From the binding post 49 a wire `56 leads to the motor. Y A

57 designates the pivoted movable inein- 'ber ot'the snap switch that cra-operates with the stationary member '41. `/Vhen thesnap switch is closed, =the motor 'is 'i energized .through the described connections, and when the snap switch 'isiopemfthe circuit is-brolren. Coin controlledateans for closing thel snap switch are illustrated :mainly lin Fig. 5,

Within 'the stationary tubularihousing 12 is mounted a nanrow casing 58 containing a coi-n chute 59 .registering with a coin slot 61 in the Wall of the housing 12. In a suitable Aguideway below the chute 59 is slidably mounted a jpusher bar 62 having a head or 'knob 63 -on its outer end.v vThis pusher bar isA normally 'retracted :bywa pull spring -64 (Fig. 2). When 'a coin, :such as tha-t indicated at 'C in Fig. l5 is'inserted in the slot, falling in front of the pusher bar, 'the latter, when pushed inwardly, 'causes'.the redge of the coin toengage with andraise fthe heel 65 ofa trigger=66 mountedA on a pivot pin 67 and at its upper end canryingia pin 68 engaged with a slct69 in a link bar '.71. The forward endostrthelink barfi71is pivote'd at 72 to aqaivoted lever 73, the 'lower end of which is connected to and actnatesthe pivoted member 57 ofthesnap switch in a wellknown manner,.-causing closing xof the switch when the link 'bar 7l is pushed 'torwardly :as described. The trigger 66, after the coin has passedfthe same, is retracted by a pull spring 74 2 .and 4) anchored at one end to apn 75 on the trigger and at its otherrend to a post 76 in the housing 58.

The mechanism for automatically breaking the circuit and arresting the lmovement .ot the fan after '.a predetermined period of service is shown mainly i-n lFigsfi and 6, and

comprises the follow-ing.

In Aand depending 'from the bottom sid-e of the plate 14 is a screia7 '77.'constituting a fixed shaft and support :for a pawl and ratchettiming mechanism. Encircling the shaft '77 is a bushing sleeve 78 (Fig. 6) on -which isrevolubly mounted the hub 79 ot a ratchet wheel 81. Fulcrnmed on the hub 7-9 -of the' ratchet wheel -81 is a lever, one

arm 82 of which carries on its free end a pivoted 'driving pawl 83, the lnose of which engages with the teeth of the ratchet wheel 81. The other arm 84 of said lever extends upwardly obliuely.tliiough an opening 85 (Figs. 3, 4 an 6) in the plate 14 and has mounted on its free end a button 86 that lies abou-'e the plane of the upper surface of the plate 114.1I Vlirttaclicdto and depending from the lower side of the rotating plate 25 is an obliqu-ely dis-posed cam striker 87, clearly sl-iown in Fig. 2, that, once during each revolution vot' .the fan support wipes over the button A86, rocking the pawl lever, and, through the pawl 83, turning fthe ratchet wheel 81 one tooth. The ratchet wheel is locked against Aback-turning by a dog-ging pawl 88 (lFig. 4) pivoted vat 89 on the plate 14 and having its 'ta-i191 connected by a pull spr-ing 92 with ythe driving pawl 83; the spring 92 acting to urge both pawls into engagement with the-ratchetfwneel. Secured `to the under side of .the ratchet wheel -81 is a radiallyprojecting tappet arm 93vthat, once during each complete revolution of the ratchet wheel 81 strikes a laterally projecting pin -or stud 94 on the switch-actuating link 71, ret-racting said link (permitted by the slot 69) and opening the snap switch; thus breaking the circuit. and stopping the fan.

The coins deposited drop int-o the hollow dish-shaped base 10,' whe-rice they arc removed rom time to time by unlocking a door 95 (Fig. 1) guarding an opening'dn *100 the wall =of the stationaryliousing 12.

From the foregoing description Aand illus- 'trationit will be apparent that :the fan is start-ed .in opera-tion Aby simply depositing -a. coin in the chute '59 and actuating thepusher 105 -bar 62 inwardly, this closing fthe motor. eircuit at the snap switch. The Imotor revolves the ian and at the .same time sets up a relatively slow revolution of the fan '

support

19, 22,' causing the fan to move bodily in 110 a horizontal circular path, thereby similarly distributing the current of air created by the fan.. At each revolution of the fan support the 'ratchet wheel 81 is advanced one tooth through eng-agement of the cam striker 87 with the lever button 86.. As soon as the ratchet wheel 81 makes one 4complete rotation, the tappet arm 93 .strikes the .stud 94,

rand thereby opens the switch and breaks lill fications as fall within the spirit and purview of the appended claims.

I claiml. In a coin controlled mechanism for operating an electric switch, the combination of a coin chute, a trigger pivoted opposite the lower end of said chute, a pivoted switch member connected to said trigger through a lost motion connection, and a push bar operating through a coin in the bottom of said chute to swing 'said trigger and thereby actuate said switch member, said lost motion connection permitting said trigger to return to coin engaging position without actuating said switch member.
