Toallwhornitmay concem:

Be it known that-I, WILLIAM F. Wnmzun'ron, of Philadelphia, Pennsylvania, have invented an Improvement in Ventilators for Hats; and I do hereby declare the following to be-a .full, clear, and exact description of the. same, reference being bad to the accompanying drawing, and to the letters ofreference marked thereon.

My invention relates to a mode of carrying out that ner as to leave a crescentrshaped opening, through which air can pass to the interior of the hat, one of the strips at the same time accommodating itself to the head, and-insuring comfort to the wearer. In order to enable others skilled in the art to make and use, my invention, I will now proceed to describe its construction and operation.

On reference to the accompanying drawing, which forms a part of this specification- Figure 1 represents an inverted plan view of an ordinary hat, with my improved ventilator;

Figure 2, a vertical section of the lower part of the hat, and of the ventilator; and

Figure 3, a perspective view of the ventilator.

Similar letters refer to similar parts throughout the several views.

The ventilator is composed of two"strips,A and B,

. of thin metal, paper and. cloth combined, in the manner practised in the manufacture of paper collars, or theymay be made of hard rubber or other suitable non-elastic flexiblematerial.

The two strips are secured together at their opposite ends by eyelets,-or otherwise, as seen in fig. 3, but in such a manner that a crescent-shaped opening, a, shall intervene between the strips.

The ventilator, thus constructed, is adjusteb to the interior of the hat, in the manner illustrated in fig. 1, the strip A being secured to the hat by stitching or otherwise, while the strip B is at liberty at all points, excepting at its opposite ends.

Owing tothe crescent-shaped intervening space between the' two strips, the strip Bwill readily accommodate itself to the forehead, and insure comfort to the wearer. At the same time the space it allows a plentiful supply of air to gain access to the interior of the hat, and causes a thorough ventilation of the same.

The ventilator may be of such a lengthas toextend nearly around the interiorof the hat. In the present instance,however, it is so limited in -length-as to afford a self-accommodating rest for thewearers forehead onl Ihe sweat-band'D may be turned, at the bottom, across the opening, a, between the two strips, and secured to the rim, small holes,:c, being made in this portion of the" band, for the admission of air to' the said space a.

I wish it to be understood that I do not desire to claim broadly a strip, secured to the interior of a hat, at such points that it will accommodate itself to the owners forehead, and at the same time aii'ord means of insuring athorough ventilation of the hat, as this is described and claimed in my reissued patent of September 8, 1863, the original patent being dated December 11, 1860; but I desire to limit my claim to the mode of carrying out .this invention described in said reissued patent; that is to say,

' I claim the within-described ventilator, composed of the non-elastic flexible strips A and B, secured together, so as to leave a crescent-shaped opening, a, substantially in the manner and for the purpose described.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

WILLIAM F. WARBURTON.
