IMPROVEMENT IN THE VENTILATORS OF HATS.

Specification forming part of Letters Patent To all whom it may concern:

Be it known that I, JOHN MoMANNUs, of the city, county, and State ot" New York, have invented va certain new and useful improvement in Self-VentilatingHats; and Ido hereby declare that the following is a full, clear, :11nd exact description ot' the same, reference being had to the accompanying drawings, in which- Figure 1 represents the under part of a hat with my improvement attached to it. Fig. 2 represents a-section through a portion of the y rim, body, sweat-cloth, and ventilator, and Figs. 3 and 4 represent the Ventilating piece detached from the hat. i

I am aware that ventilating-holes have been madein the sweat-cloth of a hat. These holes get closed up to the air, while they allow the the perspiration to pass through them, and stain or soil the exterior of the hat. 1 am also aware that corrugated metal pieces have been introduced between the lining and exterior of the hat to make these Ventilating-openings. The metal is, of course, impervious to the per sLir-ation, and it will preserve its air spaces, but it is an exceedingly uncomfortable thing to press against the head, and thus fails to come into use.

My object is to make a hat that will ventilate while on the head of the wearer, that will n'ot allow the perspiration to pass through it, that will not close up by the pressure in wearing it, and that will give a smooth bearingsurface for the head, and all these elements liind inthe ventilatiug-strip which I shall hereinafter mention, applied between the sweatcloth and the exterior of the hat.

To enable others skilled in the art to make and use my invention, I will proceed to describe it with reference to the accompanying drawings.

1 take a crescent-shaped piece of prepared rubber, guttapercha, or prepared paper, which extends around the fore part of ahat, as seen at Fig. 3 (marked A,) one side of which (marked a) is made into corrugations, and the other side, b, left smooth. This piece A is put into No. 26,692, dated January March 13, 1860.

Icorrugations simply,

PATENT OFFICE.

3, 1860; Reissue No. 927, dated the hat betw body d of the hat, the smooth side b next the head, and the corrugated side 0ll next the hatbody, and thus there is a smooth bearing for the forehead against the ventilating-pece, and the openings through it next lthe brim cannot, owing to the nature of the material out ot' which the ventilatingpiece A is made, close up. A very good way of making these ventilating-strips is to'rst mold the piece, as shown at Fig. 4, and afterward divide it, as shown by thered line therein, and thus make two out of it. This makes the holes of Fig. 4 into grooves or corrugations, as shown at Fig. 3, and the piece, Fig. 4, may be used entire, though it is heavier than necessary. 1 much prefer, however, the plan shown in Fig. 3, as it is much lighter and makes as good a ventilation.

f represents the ordinary ventilation inthe crown of the hat; but it, with the ventilator A, affords a constant circulation of air` through the hat while on the head, the hat being just as comfortable as any other hat, impervious to the perspiration of the forehead, and there being no possibility of the openings being closed up by pressure in wearing.

Having thus fully described the nature ot' of my invention, I would state that I do not claim holes in a hat sweat-cloth, nor do I claim nor corrugated met-.1l strips therein; but

What ldo claim as new, and desire to secure by Letters Patent, is-

A Ventilating-piece having a smooth surface next the head and grooves or openings nextv the brim, and made of india-rubber, guttapercha, or prepared paper, and irm enough not to crush or close up said openings, and impervious to perspiration, as hereinrepresented, and for the purpose set forth.
