COIN-CONTROLLED FAN.

Original application use November 1a, 1924, Serial ND. 750,755. Divided and this application filed June 10, 1927. Serial No. 197,780.

This invention relates to motor-operated fans of the coin-controlled type, designed mainly for use in refreshment parlors and,

breeze radially in a circle, to provide a device which will automatically start in operation upon the deposit of the coinv and will 0 erate and automatically sto at the end 0 a predetermined period, an to provide a device wherein a single electric motor will both rotate the fan on its own axis and also swing or turn the fan bodily in a circular path. I

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 illustrated in structural detail an apparatus well adapted to fulfill the stated I purposes and objects of the invention and embody the principle thereof, and in which:

Fig. 1 is an elevational view of the complete apparatus,

Fig. 2 is a vertical section of the parts below the motor and fan, r

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

Fig. 4 is an enlarged cross-section lookin upwardly on the'line of Fig. 2, ig; 5is a vertical transverse section on the line 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 of Fig. 4. i

This application is a division of my copend'ing application 759,755, filed November 19, 1924. t

Referring to the drawings, 10 designates a base late on "which is secured,-byscrews 11, a circular sheet-metal tannin- .12. To

the top of the housing 12 is secured, by screws 13, a circular plate or disc 14 formed withanupstanding annular flange 15 overlapping and extending somewhat above the upper edge of the housing 12. Secured tov the top of the disc 14 is a smaller disc 16, in the center of which is secured a collar 1.7 forming, with the discs 16' and 14,]a bearing and support 'torthe lower end of a central vertical stationary shaft 18.

v 19 designates a circular sheet-metal casing of a diameter to fit loosely at its lower end withinthe 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 topof the cap 22 is a long sleeve 23 having an'exten'ded' bearing on the shaft 18. and at its lower end attached by a flanged collar 24 to a disc 25 fitted within the lower end'of the housing 19. Encircling the collar 17 and resting upon and attached to the disc 16 by screws 26 (Fig. 3) is a stationary spur gear 27 made of insulating material.

Mounted upon the upper end of the cap 22 is an electric motor 28 operating a direct driven fan 29. The motor 28 at its rear end is geared to and drives a vertical shaft 31 that 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 themotor' 28, operating through the pinion 34 and fixed gear 27. v causes a rotation on the fixed shaft 18 of thehousing 19, cap 22, motor 28 and fan 29 p lows. Referring to Figs. 1 and 2, in the lower portion of the housing 12 is mounted an electric coupling 35 for the circuitwires 36 and 37. From the innerend 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 side of .the stationary switch member 41 a wire 44 leads from a binding post 43 to a binding post 45 that, as shown in Fig. 7. extends Currentis supplied to the motor as folot the plate 2' by an insulated bind. 1g post indicated at l-l) in Fig. 3 is a depending brush 51 whic From the lindii into the motor. from the couple of a binding po; to the binding po other end of the block of the binding EOSt 4&5 is rivetec. into a smaller ring Cal (Fig. 3} mounted in a wipes over the ring l8. post if a wi e 52 leads (ill I ver side i respects d iii the The upper end groove in the unper laoa oi the gear 27 (01 centric with the l8.

Attached to and depeniiling from the lcwrer side of the rotating plate an obliquely disposed am striker 87, clearly shown in Fig 2, that, once during each revolution of the fan support wipes over the button 86, rocking the pawl lever, and. through the pawl 83, turning the ratchet wheel 81 one tooth. The ratchet whet-i is locked against back-turning by a dogging pawl 88 (Fig. pivoted at 89 on the plate 14. and having its tail 91 connected by a pull spring 92 with the driving pawl the spring 92 acting to urge both pawls into engagement with the ratchet wheel.
