4 Claims.

This invention relates to an improved hat dusting appliance employed for removing extraneous material from hat bodies during the process of manufacture of hats.

An object of this invention is the production of a hat dusting appliance which will provide a duplex dust removing action operable simultaneously upon the outer and inner surfaces of the hat body and which will be most effective in de-dusting operations and which may be easily manipulated by .the operator.

Another object of this invention is to provide a hat dusting appliance having a crown mounted on a shaft above a tubular .suction member and having a fan rotor on the lower end of the shaft and rotatable in the tubular member, whereby the suction causes rotation of the fan rotor. the crown and hat body thereon.

Another object of this invention is to provide braking means for controlling the said rotation, the said braking means being operable by a foot treadle.

Another object of this invention is to provide an upwardly extending enclosure ,circumscribing the lower portion of the crown for concentrating the air suction around the crown downward into the tubular suction member.

Another object of this invention is to provide .angularly disposed baffle plates all around the front opening of the booth, the said plates converging .towards the center of the funnel-shaped member and serving to prevent the dust from backing out of the booth.

With the above and other objects in view, the invention will be hereinafter more particularly described, and the combination and arrangement of parts will be shown in the accompanying drawlugs and pointed out in the claims which form part of this specification.

Reference will now be had to the drawings, wherein like numerals of reference designate ,corresponding parts throughout the several views, in which:

Figure l is a front elevation, partly in section, of the improved hat dusting appliance.

Figure 2 is a cross-sectional view, the section being taken .as on line 2-2 in Figure 1.

In the illustrated embodiment of the invention, the numeral l indicates a hat dusting appliance comprising a booth H for box-like form mounted on legs I2 which bring the bottom Wall [3 of the booth on a level suitable for hat dusting operations. r

The bottom wall l3 has a large aperture M in which has been secured a funnel-shaped memher [5 having a tubular extension [6 positioned below the bottom wall. A frame ll preferably made from metal bars 18 has been mounted in the funnel-shaped member [5. The bars I8 have angularly bent outer ends H! which fit the tapering walls of the funnel-shaped member and'provide a positive support for the frame l1.

Bearings 20, 20 preferably of the ball bearing type have been secured in axial alinement to the upper and lower sides of the frame l1. The bearings 20, 26 are positioned centrally of the funnel-shaped member i5 and provide a mounting for a vertical shaft 2| which extends downwardly into the tubular member It. A fan rotor 23 has been fastened to the lower end portion of the shaft 21 and is operatively positioned for rotation in said tubular member 22. A grooved disk 25 has been secured to the upper end of the shaft .2 I.

A spoked disk 26 has been fastened to the uppermost end of the shaft 2| for horizontal rotation with said shaft.

A crown 21 preferably formed of aluminum has been mounted on the spoked disk 26 in coaxial relation therewith. The crown 2! is hollow and substantially dome-shaped and is perforated all over with a series of apertures 28. A downwardly directed flange 29, preferably formed of aluminum, has been removably mounted on the lower edge of the crown 21. The flange '29 is perforated all over by a series of apertures 30. The flange 29 is adapted to receive and support thebrim of a hat body. The flange 29 may be either ,fixed to the crown or adjustable relative to the crown and made to conform to hats of various styles.

A suction blower or air exhauster (not shown) has its suction connected to the tubular extens'ion or suction member E6. The down draft suction through the fan blades causes rotation of the fan rotor 23, the crown 27 and the hat body placed on the crown.

A brake lever 3| has been mounted on a-pivot 32 carried by a bracket 33. The bracket 33 may be secured to the upper bearing 20 or held'in any other manner fixed to the frame H. A compressionspring 34 positioned intermediate the lever 3| and the bracket 33 serves to urge a tapering brake member 35 into pressure engagement with the grooved disk-2 5 and acts as a braking means for controlling the rotation .of the fan .rotor and the crown and hat body. A foot trea-dle 36 is suitably connected by means of a rod 31 with the lever 3| so as to normally hold the rear end of the treadle in a raised position. The op- .erator presses on the foot treadle to release the brake so that the hat body will be revolved due to the pneumatic force. Release of the foot ,treadle arrests the motion of the brake.

.A wire mesh screen 38 has been mounted on the frame ll. The screen prevents hat bodies from being drawn into the suction fan.

The booth H has baiile plates 39 which are angularly disposed all around the front opening 40 of the booth. The baflle plates converge towards the center of the funnel-shaped memher l and act as a dust reversing means which causes the dust thrown off from the hat bodies to stay inside the booth and prevents the dust from striking the operator in the face.

A circular enclosure 4| circumscribes the lower portion of the crown 21. The enclosure is of the same diameter as the upper diameter of the funnel-shaped member l5 and serves for concentrating the air suction around the crown.

An air nozzle 42 controlled by a lever 43 carries a hose 44 which is connected to a high pressure air supply (not shown).

In operation, the suction fan is started and the hat body is placed on the crown 2?. The suction holds the hat body firmly on the crown. The operator presses on the foottreadle. The down draft suction through the fan blades causes rotation of the fan rotor, the crown and the hat body.

The operator manipulates the lever on the high pressure air nozzle and points the nozzle to the hat body. This externally applied jet of air passes through the hat body. The interior suction sucks down the particles loosened by the external blast.

The effect of the duplex dust removing action is that it takes less than one minute to clean a hat. The hat may be turned inside out and the cleaning operation repeated on the interior surface of the hat.

The speed of the rotating shaft and hat body is controlled by the foot treadle which leaves both hands of the operator free for the dusting operations.

The importance of the booth structure herein disclosed is that it serves as a health and sanitary factor for the operator, eliminating the breathing by the operator of the die dust loosened from the hat body. The booth concentrates the dusting operation in a confined area.

,The importance of the down draft suction inside the hat body is that it holds the hat body down on the crown, while without the suction inside the hat, the operator is compelled to hold the hat body on the crown with one hand while operating the compressed air nozzle with the other hand.

If an electric motor were used, the continual stopping of the motor would become a hindrance to successful operation besides being a fire hazard, due to sparks caused by the starting and stopping of the motor, the dust being inflammable. The use of an electric motor would necessitate the complication of belts, speed reduction equipment, and'complicated switch devices, such as switches of the mercury type, while the structure shown is of extreme simplicity. The down draft suction simplifies the structure for causing rotation of the crown and hat body. V I claim: 7
