'INVENTOR To all whom it may concern.:

Beit known that L'DARio RonER'rI, a 4subject'of the King of Italy, residing at New-` ark, .in the county of Essex and 'State oi -NewJersey, have invented certain new and `useful improvements 1n Spring-Fans; and

l `do hereby'declare the following to be a full, clean,- and.` vexact description of the invention', such as will enable others 'skilled inv-the' art to Kwhich it appertains tomake andu'se the'same, reference being had to the accompanying drawings, and to figures of referencehmaa'ked thereonwhich form a part oli this specification.

This invention relates to an improved fans, and particularly to a portable fan that isinounted on a standard and has a rotating i consisting of blades, the pitch of the bladesbeing adjustable so that the force of thefcurrent of vair being propelled can be i regulated.

The invention is further designed to provide a fan that is operated fromA a spring motoreuid is 'provided with a brake attach-` nient" so; that the speed of the fan can be 4 regulated. v still *further,improvement consists in thexfiiountilng of the fan and its casing on a. Vstandard so that it rests thereon. 1n a fixed. position', or it can be arranged to rotate .stead-'lily i-n a certain direction to dis- .tribiitetheair to: better advantage, the rotaining apparatus being actuated by the same springer lsprings that-actuate the fan blades.

Theldeviee alsoicormprises a music-box attachment-'which canjbe -placed in or out of z-perai'fivel connection with a mech anism for propelling l the y fan.'

.'llieinvention is' illustrated in the accompanyiing drawings, in. which- Figune "1v is'af face view o l" the fan with and its standard., showing the casing in section.` iFig. wis afrearview of the device with-the casi-ng broken away, and Fig. l is a verti'cahcentralf section through the spring and'thetransinission'gearing. Figa 5y is a. detail vi`evvf oit' thehub ofthe fan and the methodof attachingy the blades.

The device consists oga 'hollow' standard .1-0- which can be of any usual configuration and is provided .with a centrally arranged rod 11 which is rotatably -mounted in the standard and also '..lnovable `longitudinally therein as will be, described hereinafter, a1-

secured to the rod 1l.

though the longitudinal movement is not necessary where the fan is to be made fixed to the standard. Mounted on top of the rod 11 is a casing` 12 having a bottom 13 To the top of the rod 11 isl secured a block 14 from which eX'- tend. the uprigh'ts 15 and 1G which extend upwardly and between which are mounted the springs 17, which springs have one end,-

'as 18, of each one secured to theuprights, the other end of each spring being.' secured as in Fig.` t, or any other suitable Way, to a sleeve 19 which is arranged to rotate on the shaft 20, the shaft 20 bei-ng held against rotation by a squared or rectangular portion 21,011 the fron-t end, which fits in the up- I right 16.

The usual ratchet 22 is secured to the end ofthe sleeve 19 to hold it against unwinding, except with the gear 23 to which the ratchet 22 isfastened, the pa wl Q4 (co-acting. with the ratchet, being normally held down by the spring 25. Secured by al screw 26 tothe upright 15 is a bracket 27 which is provided with a rotatable shaft Q8 having. projections to fit in the recesses in the shaft 20 or. 'any4 other detachable operative connection which is operated from the gear 29 which in turn is turned byv a gear 30, the shaft of which has a squared portion 3l to receive a lever 32 of the handle 33 so that the spring'- or springs, if more than one is placed in para-lilel relation, can be wound.

lt'otatably arranged on the rod. Iifl is a sleeve 35 on which is .secured a. gear 36 wuirii meshes with the gear 22K, and on the outer end of the sleeve is placed a. large gear 37, the shaft exteiiding beyond the gear and being mounted in a plate 38 which is fastened by any suitable means to the upright 16.' This train of kiggearing that has been described and the description of which will be continued is designed to increase the revolutions. The gear 3T meshes with a. gear 3S which is mounted on the same stud 3921s a larger gear 40. The larger grai- 40 meshes With twosinaller gears'll and l2 which are mounted slightly below and on each side of thev center of the gear 40,. these gears rorespectively, which both' mesh with a smaller ies' gea1-45 which 1s mounted on a small shaft .457 beit, t fastened to the shaft 4S which is the'sha on `whicl1the tan ismountod. The

shaft [t8 rotates in a tubular bearing 49' -tened by a suitable set-screw 53, holding the shaft in place and also acting to hold the fan, sinceit is integral or secured to a disk t which is adjustable toward and from a disk by means of the screws The blades 57 are provided with studs 58 which tit in the recesses inthe opposed faces of the disks 54 and 55 and can be fastened at a desired angle, but when the screws .36 are nnloosened they can be turned so that the pitch can be regulated. A frame 59 is suitably' fastened to the front of the casing l2 and has the arms 60 to protect the fan blades from damage and an unwary person from injury. These arms are joined by a disk Gl to which is secured a hollow. cap (S2 in which is slidably arranged a rod 63 which has a head G4 thereon, the head being recessed as at 65 to receive .the pointed end 66 of the shaft 48.

A spring 67 pushes against the collar 68 having one end abutting thereon and having thev other end abutting against the disk 61 so that the head (54 is normally pulled away from the end of the shaft 4S, but a screw 69 can be used to force the rod (53 against the action of the spring, and a braking action can be put on the shaft t8 to regulate the speed of the fan. The gear 23 meshes near the bottom of the casing with a. smaller gear- 'wheel 70 which is mounted on the shaft 7l and is provided with a beveled gear 73. he beveled gear 73 meshes with a fixed beveled rack 74 of a circular form which supports a disk 72and' between this disk 72and a plate 75 on the bottom of the casing are the balls 7G which form a ball-bearing. lVhen the sprii'ig is wound up the fan can be held against rotation by the brake being placed in engagement with its shaft, and after the spring is wound the brake can be released and the transmission gears between the spring and its shaft and the fan and its shaft will cause a rotation of the fan for a long time at a high speed with a slight relaxation of the spring.

Then the fan rotates the gear 73 rotates to vary its speed. a spring to norn'ially withalso on account of its connection with the l shaft of the spring, and engaging the circular rack on the standard it causes the casing to revolve on the standard so that l the current of air is distributed around a room or in the vicinit)v of where. the fan is placed. To prevent the rotation of the casing the shaft l1 can be raised by the. lever 77 which is pivoted intermediate of its ends at 'T8 to the inside of the casing, and which has its end `opposite the one engaging'i'the bot-tom of the rod 1 1 adapted to be forced downward by the stud T9 on. which the linger-piece 80 is arranged. lVhen the finger-piece S0 and its stud TE) are forced down the rod' ll is shoved up so that the gear T23 is discoi'mectcd from the rack T4. 'the stud T5) slides in a thimblc Sl which has a recess S2, and a pin 83 passing through the stud tits in the recess 82, when the casing is down and adapted to be rotated, but

when the ngenpiece 80 and its 'stud 79 are pushed down to raise the rod il, the linger-piece is slightly turned and the pin 83 is placed at an angle to the recess 82 and the rod 1l, and the easing with its fan is prevented against descending and thus stands rigid in any position it. is placed, but it can be rotated easily by hand to adapt it. for throwing the air current. in any desired direction.

,lf desired, a musical attachment can be provided which consists of a frame 84: having the ordinary roll'S therein which e11- gages with a series of spring forks or strips, the frame being n'iounted pivotally on a rod 86.

The device is operated by a gear meshing with the gear il() of the driving mechanism and is actuated, that is, the gear 90 is held into or out of mesh with the gear 3G by a. handle 8T which has a linger 88 which is adapted to tit in the holes Si) in the back of the casing l2, as will be seen from Figs. 2 and 3.

A fan comprising a standard, a casing on the standard, a spring motor in the casing, a fan mounted on the front of the casing, means for operating the fan from the spring motor, a guard surrounding the fan, and an adjustable brake mounted in the guard and adapted to bear on the end of the fan for aeving its speed.
