Nov. 30, 1943. s. J. BACHARDY REMOVABLE COOLING UNIT FOR HATS Filed Jan. 28, 1943 INVENTOR.

Jake/1 m 6 Ar THRIVE) Patented Nov.-30, 1943 UNITED STATES PATENT OFFICE REMOVABLE ooorme'om'r 'roa na'rs StephenJ Bachardy, Allentown, Pa. Application January 28, 1943, Serial No. 473,813

'1 Claims. (on. 2-1) This invention relates to new and useful improvements in a removable cooling unit for a hat.

More particularly, the invention contemplates material which may evaporate or decompose into a gas, and so readily escape.

Still further the invention proposes simple and effective means for supporting the vacuum container within the hat. 3

An arrangement is also proposed for efiiciently I conducting heat from behind the sweatband to the interior of the vacuum container so that it is absorbed and neutralized.

For further comprehens1on of I the invention, and of the obiectsand advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set fo'rth.

In the accompanying drawing forming a material .part of this disclosure:

Fig. 1 is a side elevational view of a hat provided with a removable cooling unit constructed in accordance with this invention.

Fig. 2 is a bottom view of Fig. 1.

Fig. 3 is a fragmentary longitudinal sectional view of Fig. 1.

Fig. 4 is a perspective view of the conducting member, per se.

Fig. 5 is a longitudinal sectional view of the vacuum container of the device.

The removable cooling unit, in accordance with this invention, is intended to be used in combination with a hat III of any design or construction having a crown II and a sweatband I2. The cooling unit includes a double wall vacuum container I3 having a neck opening I 4 through which dry ice or other suitable refrigerant may be place therein. A vented stopper I5 is provided for normally closing the neck opening I4. This stopper I5 has a vent passage I6 for the escape of gas if the refrigerant is dry ice, or for the escape of other vapor substances if the refrigerant is of a different nature.

Means is provided for supporting the container I3 within said h'at III. This means comprises a strap I! attached within the crown II of the hat and having a loop portion I8 through which the container I3 is engaged. Said container is provided with a groove IS, one side IQ of which forms wall l9 which is arranged close to a portion l3 0f the interior wall l3 of the container I3. The other wall I9 of the groove of the container I3 is also arranged close to a depressed portion I3" of the interior wall I3, leaving a narrow space I3", compared with the wider spacing I3 all around, between the walls of the container I3. Through the closely spaced walls I! and IS", the cool air may efficiently radiate from the interior to the exterior of the container. A

heat conducting member 20 is provided with a t p portion 2| normally engaged within the groove I9, and a bottom portion 22 normally engaging behind the sweatband I2 of the hat.

The conducting member 20 is shown constructed of three sections, indicated by the numerals 23, 2t and 25. These sections may be of different materials having different conducting coeflicients. For example, these sections may be of lead, copper, tin, or foil of other kinds of sheet material.

It should be noted that the closed end of the container I3 flares outwards (see Fig, 2) for a distance sufilcient to extend around the brow of a person wearing the hat. The sections 23, 24 and 25 are each of a width corresponding with the width closed end of the container. With this arrang'ement it is possible to shift the conducting member 20 so that one of the sections or the other of the sections of the conducting member are located behind that portion of the sweatband which engages the brow.

With this invention, heat from the brow will be readily conducted and this will remove the discomfort of wearing a hat, particularly when it is warm. Most persons perspire at the brow when wearing a hat, and it is calculated that this invention will eliminate this discomfort.

The amount of spacing I3" between the front bottom wall I3 and the wall I9", above the brow of the wearer, will be experimentally determined to produce the desired temperature above the brow.

This cooling unit may be refilled with dry ice or other refrigerant, in hot days and the vacuum container may be entirely removed from the hat in normal or cool weather.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the. precise constructions herein disclosed and the right is reserved to all changes and modifications com- 2 assaeao ing within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:

1. In combination with a hat, a removable cooling unit, comprising a double wall vacuum container having a neck opening through which dry ice or other refrigerant may be placed therein, a vent 'stopper for said neck opening, means for supporting said container within said hat. said container having an innerand outer wall evenly spaced from one another, except at a comparatively small area opposite the neck opening, where the spacing is considerably reduced for efiicient heat absorption at the brow of the wearer.

2. In combination with a hat, a removable cooling unit, comprising a double wall vacuum container having a neck opening through which dry ice or other refrigerant may be placed therein, a vent stopper for said neck opening, means for supporting said container within said hat. said container having an inner and outer wall evenly spaced from one another, except at a comparatively small area opposite the neck opening, where the spacing is considerably reduced for efficient heat absorption at the brow of the wearer, said container having a grooved portion in the vicinity of the reduced spaced portion of the container, and a heat conducting member mounted in said groove projecting downwardly therefrom.

3. In combination with a hat, a removable cooling unit, comprising a double wall vacuum container having a neck opening through which dry ice or other refrigerant may be placed therein, a vent stopper for said neck opening, means for supporting said container within said hat, said container having a grooved portion one side of which forms a narrow space with the interior of said container for eificient heat absorption to the interior of said container, and a heat conducting member mounted in said groove and having a portion for extending against the in ner face of the sweatband of said hat.

4. In combination with a hat, a removable cooling unit, comprising a double wall vacuum container having a neck opening through which dry ice or other refrigerant may be placed therein, a vent stopper for said neck opening, means for supporting said container within said hat, said container having a grooved portion one side of which forms a narrow space with the interior of said container for efficient heat absorption to the interior of said container, and a heat conducting member mounted in said groove and having a portion for extending against the inner face of the sweatband of said hat, said vent stopper having a passage for the escape of gas.
