AUTOMATIC SPRING-FAN.

1 354 931? Specification of Letters Patent.

Patented Oct. 5, 1920.

Application filed October 15, 1919. Serial No. 338,735.

To all whom it may concern:

Be it known that I, PAUL Prs, a citizen of Poland, residing at .Detroit, county of .Vayne, and State of Michigan, have invented certain new and useful improvements in Automatic SpringFans, of which the following is a specification.

The principal object of this invention is to provide a spring motor driven fan, adapted to be angularly adjusted from a vertical plane or revolved horizontally through a complete circle.

Another object is to provide a gear driven, spring operated fan motor, having adj ustable bearings by means of which an air current from the fan may be forced in any desired assembled structure. V

Fig. 4 1s an enlarged transverse sectional view of the adjustable bearing, taken on line 4-4 of Fig. 1, and

Fig. 5 is an enlarged transverse sectional view taken on line of Fig. 1 showing the spring, gear and interior of the spring casing.

Referring to the drawings in detail, the numeral 10 designates a frame or casing having a removable cover 11 secured by the bolts 12. Rotatably held within the frame 10, are three vertical spindles 13, 14 and 15, the spindle 13 having fixed upon its upper portion the spur gear 16 and along its lower portion the pinion 17. Meshing with the pinion is a spur gear 18 fixed upon the spindle 14 and in'mesh with the spur gear 19, freely revoluble upon the spindle 15. I

A motor case 20 contains a flat spiral spring 21., secured to the case-2O at its outer end and having its inner end secured to the spindle 15.

This spring may be wound by the bevel gears 22 and 23 secured upon their respective spindles 1.5 and 24 and retarded in unwinding by a ratchet wheel and pawl of usual des1gn.

The shaft 24 is rotatably mounted upon the bracket 25 secured to the cover 11, the extension 26 of the spindle 24 being located within a slot provid d in the end of the frame 10. 1

A winding crank 30 is screw-threaded into the extending element 26 and has a handle 31 thus providing a key or winding means.

A hollow upwardly extending bracket 82 is attached to the front end of the frame 10, by the lugs 33 and the screws 34, the bracket having a removable bottom 36 containing a conical recess, forming a thrust bearing 32'.

At the upper end of the bracket 32 is rev olubly oiu'naled, contactable with the flange 38, a hub 39 having an extended arm 40 and integral with it, the two upright housings 41 and 42. Within the bracket 82, is a pinion 44 secured to the spindle 45 and meshing with the spur gear 16.

Secured upon the outer projecting end of the spindle 45 is a bevel gear 46, in mesh with the bevel pinion 47 secured to the fan shaft 48, rotatable in the housings 41 and 42. A. multi-blaoed fan and spider 50 of usual design is removably attached to the shaft 48 by the nut 51 and a protecting frame or guard 52, of usual design, is attached by the clip to a lug 54 integral with the hub 39.

The fan shaft 48 is journaled within the adjustable floating bearings 60 held within the housings 41 and 42 and adjustable vertically and annularly by the winged screws (Si and 62 acting against the tension resistance of the springs 63 and 64.

In operation, the spring motor is energized by actuating the crank, its power being transmitted by the gear train to the shaft 4: 2t an advanced rate of speed and even tually, under normal conditions, causes the fan to operate.

If it be desired to disengage the bevel gears, so as to render the fan quiescent, the screws 61 are relaxed, permitting the springs to raise the shaft, thereby disconnecting the gears.

Due to the mounting of the hub at the end of the bracket it will be obvious that the fan may be turned into any position desired so as to project a current of air as may be re quired.

Having thus described my invention and set forth the manner of its construction, application and use, what I claim as new and desire to secure by Letters Patent, is

In a spring actuated fan, the combination with a casing, and a spring operated gear train therein, of a vertical shaft operable by said geartrain, a hollow support for said shaft, an arm revoluble on said hollow support, housings fixed on said arm, blocks vertically movable on said housings, a shaft journaled in said blocks, a fan carried by ated to raise said blocks whereby said gears 15 are disengaged, and manually operable means for holding said blocks in position to cause engagement of said bevel gears.

In testimony whereof I have affixed my signature.
