IMPROVEMENT IN HAT-VENTILA'roRs.

Specification forming part of Letters Patent No. 129,866, dated July 23, 1872.

To whom it may concern:

Be it known that I, GEORGE B. SMITH, of Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Improvement in Self-Adjusting Hat-Ventilators; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon, and being a part of this specification, in which- Figure l is aperspective view of the front part of the interior of a hat, showing my ventilator in place. Fig. 2 isa perspective view of the ventilator detached, and, Fig. 3 is a modification of the same. Like letters refer t0 like parts in each ligure.

This invention hasfor its object to provide a simple, cheap,but effective ventilator attachment for hats of all descriptions, which can readily be inserted inthe space between the sweat-band and the body of a hat, so that spaces will be left between the sweatband and the wearers forehead for the circulation of air 5 and it consists in a flexible band of metal, rubber, or other suitable material, encircling the sweat-band, behind which it is inserted, and provided for one portion of its length with flexible plates or iingers, which overhang the sweat-band and readily conform themselves to the contour of the wearers head, spaces being left between the said plates for the passage of air up into the crown of the hat. y

In the drawing, A represents a portion of the crown and rimof a hat, and B the usual sweat-band. C is a flexible stripy of thin sheet metal, hard rubber, or other suitable material, which is slipped down between the sweat-band and the body of the hat. At one part of its length it is formed with plates a or fingers b,

as seen in Fig. 3, which are bent over the face of the sweat-band. In either case, being ilexible, they adjust themselves to the contour of the wearers forehead, and by their light pressure keep the hat in place, while they allow a free circulation of air over the wearers head, which becomes a cooling 'current if the hatcrown be perforated to cool the heated brow and top of the head, where heat is chiefly felt. Onacold daythehat maybe reversed orthe ventilator shifted around to the back of the head,

when it will cease to act as such. The wider plates a may be perforated to avoid the obstruction of the perspiration, and to expose a greater surface of the skin to the air-current. The narrow lingers b need not be perforated. These latter are best adapted to the purpose if made of metal and plated with gold, silver,

or nickel. The ends of the plates or fingers should`be turned toward the sweat-baud to prevent them from lying iiat against it, and also to prevent them from catching the hair or abradingthe skin.

In using and attaching this ventilator the wearer uses a hat a little larger than the size ordinarily worn by vhim, and it may be in a moment transferred from an old to a new hat.

What I claim as myinventiomand desire to secure by Letters Patent, is-

The flexible strip C, provided with the elastic perforated plates a or fingers b, substantially as and for the purpose set forth.

GEO. B. SMITH.
