:cillatingtype operated :bj/"1a spring motor directly or in combination with an air pump and a rotatingdevice inV connection with the fan shaft. The Yprincipal obj-eet of the inventionis to provide a new and improved fan construction which maybe operated bymeans ofa spring motor and to utilize' stored up energy of a spring through the intermediar'y of a pneumatic. device for rotating the fan. A further object of the invention' is `to provide a new and improved rotating device which may be used in connection with a fan or any other device which it is desired to rotate. Other objects will appear hereinafter. f
In the accompanying drawings, Fig. 1 is a section elevationv of a fan constructed in accordance with t-he principles of this invention; Fig. 2 illustrates a modiiied form; and Fig.` 3 shows a detail of the rotating device. A fan having a plurality ofblades 4t secured :to the end of a shaft 5 and has a protecting guard 6 composed of wires or the like secured to the fan shaft or to the casing 7 iii which the fan shafts mounted. It the fan is of the oscillating type an elongated opening 8 is provided in the casing to permit such movement of the fan. A bearing 9 supports the shaft 5 and is mounted v:for free rotation about a vertical axis by means of a hanger 10.
Between the fan and the bearing 9 is a conical housing 11 which is secured against rotation with the shaft 5, as by attaching it to the bearing 9. Within this housing and secured to the shaft is a spiral corrugated or luted member 12 which iits the housing closely and provides varies in a' passage which diminishes in diameter trom the inner -to the outerend of the 'housing 11.v At the inner end is an air or "Huid inlet 13, and at the outer or reduced end of the housing is a discharge opening 14 through which the air or fluid mayy escape. The spiral member 12 may be ormedor `thin sheet metal orany other-light material which will maintain a permanent vviiuted. forni, Aand the inletV 18j is i inclined, as shown inFig. 3, so'that the in Vcoming an will directly impinge the varies'v `of the iliited*v member andwvill impart the maximum rotative eiioit to thes'haft 5 and the'fan. f
' "In order to supplyairvunder pressure for rotating the fan, a `spring l'which is wound by means offa key16, has al tra-in' of gears 17, 'the last ofwhich is mounted upon ashaft 18l carrying a disc19. This disclias a cam or crank arm 2O pivoted tov a piston 121 and reciprocated ina cylinder22 bythe rotation of the disc to"force air therefrom by means of a pipe" the end of wli'iehisoonnected by a flexible hose 24 withthe inlet'13L` A check l". i y
valve .25.-may be providedy at any pointin the pipe line to prevent that pressure.
To oscillate the fan the bearing 9may be A. provided witlidepending projections 26 and 27 on oppositeI sides of the center ofthe hanger 10 in position to be engaged by'coiresponding projections 28' and 29 on opposite sidesof the disc 19. The rotation ofthe disc willc aiise 'the' projections on vone side to engage, moving the fan in one-direction, and the continued rotation of the disc. will enga-ge the projections on the other side thereof` to move the fan inthe opposite direction. Any
other suitablemechanism for oscillatingfthe l,
fan by .means of fan may be employed.
Instead of driving the iiuid under pressure, aspring motor 30 may be directly engaged to a' fan 31 through a' ytrain of reducing-gears 32.
In' operation 'the ian motor iswound up by hand andthe unwinding of the spring furnishesthe vpower to rotate thedisc 19 and furnishes lair under pressure .through the 'liuted device`12 Ain the housing 1l, impart' operated for a considerable length of time I operate the piston 21 in-the'cylinder which 10o di depending upon the power of ithe spring i *motorr` and the amount of'energy thatcan A be stored therein. The fan may be operated by air or Huid under lpressure supplied from any source and appliedl to the devicel2and if desired, cooled air maybe employed'whichy is driven out or scattered by the fan after it escapes from the opening 14.- of the device l2,
claim: l. ln c nnliiimti-fr7 a springv motor, a fan, and pneumatic means operated by the motor for in'ipartingrl rotation to the fan.
2. A' fan in combination With a spring motor and a disc operated by the motor, of pneumatic means comprising a pump having an operating connection with the disc and a vaned device actuated by the pump and attached to the fan :tor rotating it.
3. jx 'ian mounted at one end of a shaft,
means *for inountii'ig the shaft to rotate and to oscillate about the other end, pneumatic means including' a pump and a device mounted on the an shaft for rotating it, and
'for oscillating the tan shaft. 4. A. tan mounted at the end of a shaft, means for mounting the shaft to rotate and to swing transversely, pneumatic means includingr a pump. rtud device mounted on the tan shaft for vrota-ting it, and motive means including a rotatable disc for oscillati ing the fan shaft and Jfor operating the pump to energize the pneumatic means.
5. The combination with a fan, of a shaft on which it is mounted an oscillating bearing in which the shaft rotates, a housing attached to the hearingI and diminishing in size toward the fan with a peripheral opening at end thereof. a tinted pneumatic device fitting Within the housing attached to the shaft and forming a vaned spiral path from the inlet to the outlet openings and means to oscilla-te the bearing, and air pressure means for rotating the device.
6. In a fan, the combina-tion with blades attached to shaft7 of a bearing` to support the shaft tor rotation and transverse, oscillation. a pneumatic device comprisinga nonrotatable housingY of conical form, and a spiralkvaned device Within the housing secured to the shaft., means for admitting air under pressure, a spring motor, a disc rotated by the spring roller, a crank connection with the disc for operating the pump,`
and projections on opposite sides of the longitudinal center of the bearing and on opposite sides of the disc for correspondingfengageinent to produce oscillation of the bearin n when the disc is rotated.
