Applicatiomfl-lefl Januaty 1 Louis, in the State ofMissouri, ha.ve mven tecl Certain new and usefi-ul Improvements-m Oscillating EleetricFans, 01% whieh the following is a spec'ification.

'lhe prin'cipal bj.ect of my invention is a new and improved meehanism f01' oscillating an electxic fan. Ano'ther 0bjeot of my invention is fio provide an oscillatin-g mechanism c0mprising a yield'mg ele- 1nent so that the fa-nmay not. become damaged. i'f it 1S' bloeked in any partieu'lar position. A furher object 0f my invention is t0 provide an oscillating fan that may .be quickly adjustecl so that; the mean posntion shall be in any desirecl horizontal direction. Still another objeet of my invention is to provide oscillating meehanism such that the fan may be tiltecl at any desix'able vertical angle While the ax'1s of the oscillation remains vert'1eal. All these objectS and various others will be made clearin the fol-lowing specification and; olai-xns, taken in counection witl1 ehe amompa-nying drawings.

' F01 tl1e putpose of illustratilmg mgy invention and explainin its nature,v 1 have Shown one specifie embo iment thereof in the acand I 110W proceed to eXplain the same.

The fan stands 011 the base' 01' support 15, to whieh the heacl 17 is attached by means-of 1 01103011113 16, this jo'1nt permitt'mg the parts 130 be assembled, as shown in the drawings, 0r to have the base; :11rned at 90 So=that iccan be supported against a vertical Wall. The head 17 ca-rries the; st1'1d 18, 0n the upper art -of which the member 19= '1 s rotaa tal0ly. Inouned. Thi'smember earnes two -roimcls.tle stud 18 between t0 thismovement, as,

'0f oscillating oppositely projeeting arms 20 that support the fan motor 22 earrying the fan 21.

Theshemft 23 pi the mdtor 22 carries a wenn 24 at its end, which engages tl1e wenn wheel 25 and,- through a train of redueing -gears 26, tnansmits rotation to the bevel gear wheel 27 0n the shaft 28.

In alinement with t-hissl1aft 28 is the serew stud 29, which may be manipulated by means of tl1e' winged laeaxl 30. The shaft 28 and the stud 29 are sup-ported 011 the ends 0f tl'1e respective arms 20 and constitute a horizontal axis ab0nt Which the motor 22 may be tilted in a Vertical plane.

One arm 20 carries a bevelecl gea1 wl1eel 31 thatis engaged by the gear 27. The shaft f0r tl1is gear wheel 1s journaled in tl1e sleeve 32 and earries a crank disk 33 at its lower end. The stud34 in the disk 33 constitutes a wrist pin which engages 0ne end 0f the link er con-necting 10d 35. Theother end 0t' the link 35 is engaged by the stud 38, attaehed to the collar 36 that loosely surohe l1ead 17 and the member 19. This collan 36 has a por-v tion 0f one side cut away, -as inclicated. by the referenee nu'meral 37, and the Stud 38 is in this cutaWay portion. The collar 36 has a deep noteh 39 ab one side,;in whioh lies a dog 40 with a downwardly projecting tongue 41 carrying -two teeth41 that engagethe notches 42 around t-he periphery of the a soc'ketz- 43 in Whieh lies a e0'11 spring 45. The screw 44, actin-g upon the spring 45, holds the dog in the notch 39 and holds the teth in enga-gement with.t he notches 42. As themotor 22 revolvesancl drives the fan 21, a .slow rotation is given tln0ugh the ge;aring deseribed to tl1e cr'ank clisl 33. Tl1e Stand 38 being fixed, the reeiprocation 0'f tl1e link 35 eauses the n1otor 22, and tl-1e fan 21 Wi= ch i.t, 130 os'eillate about tl1e stud 18 as an 8315.

In case it is desired to'have the general direction of the blast fron1 the fan changed, in other words, to change the mean position of the fan, the attendant can seize the cage and shift it while the fan is running 017 idle. This will simply slicle the teeth 41 over the notches 42 until they are brought to a suitable point of adjustment.

By means of the winged head 30 of the clamping sCrew the fan can be tilted up or down at any desired angle. that the bev el gears 27 und 31 maintain the continitv of the ear train 'for any tilting adjustrnent desire I No matter whether the fan is tilted.up or down, it oscillates alvirays about the stud 18 es a vertieal axis.
