SAFETY HA1 Filed Ilay 21, 1928 HIS ATTOe/VE).
l-I selves from falling the metallic Patented Sept. 23, 1930 UNITD STATES PATENT OFF i crz SAFETY I-IAT' Application filed May 21,
The invention relates to a safety hat, and particularly to the type of hat worn by miners and firemen.
An object of the invention is the provision of a safety hat having a supporting bracket for holding a light.
Another object of the invention is the provision of a safety hat having a supporting bracket which is insulated from the hat.
My invention possesses other objects and valuable features, some of which will be set forth in the following description of my invention which is illustrated in the drawings forming part of the specification. It is to be understood that I do not limit myself to the showing made by the said description and drawings, as I may adopt varying forms of my invention within the scope of the claims.
Referring to the drawings:
The figure is a perspective view of a safety hat equipped with the supporting bracket of my invention.
Safety hats of the type used by miners, firemen and others, who must protect themobjects, charged wires, and other hazards, are generally made of nonconducting materials. However, in many of these occupations it is essential for the wearer of the hat to carry a lamp, either an electric lamp or an oil lamp, which is preferably carried by a bracket. riveted to the hat. It is not infrequent that a worker snags a live wire with the supporting bracket, and is shocked or burned by the current which passes thru fastening means to the wearer. It is therefore the broad object of my invention to provide a safety hat having a light supporting bracket which is mounted on and insulated from the hat.
In detail, my invention comprises a safety hat of non-conducting material, and having abrim or visor 2 suitably secured to a crown portion 3. The hat construction is described in detail in my co-pending applications for United States Letters Patent, Serial Numbers 166,616 and 203,825, filed February 8, 1927, and July 6, 1927, respectively.
A lamp supporting bracket is provided which has an aperture 7 and a slot 8 in which a lamp may be detachably seated. The bracket preferably formedof thin and comprises a central sheet metal;
or upright portion 11,
a lower flange; 12- extending 'at an angle of about45 from one side thereof and an upper fiange13 extending at an angle of substantially 90 from the other side of the central portion. The sides 14 of the bracket are rolled or bent over to form a channe the device material 16 provided to absorb l to reinforce and to hold the strip of-fibrous heat from the lamp. This is particularly desirable when a carbide lamp is used, as it generates a con-' to the brim 20f the hat by which wouldcause y warmiif the.
ofthe bracket is secured 1 the rivets 17; and
since the material from which the hat is made is a non-conductor ofelectricityyand no portion of the head of the rivets on the underside, this met ing is perfectly safe.
wearer touches the.
hod of fasten- This however, is not the case with the opposite end of the bracket. The head of the user is likely to be in contact with the inside of the crown so that rivets driven directly thru the bracket into the crown could transmit a current dangerous to the wearer.
To provide against this a strip 21 of insulating material is secured to the crown 3 by the rivets 22. The
strip is preferably bent outwardly over the heads of the rivets so that they lie under the strip and are protected by it against accidental contact with a live wire. The upper flange 13 of the bracket is then secured to the insulating strip by the rivets 23. The space 22 and 23 is such that there is the current arcing across the ga between the rivets no danger of Should the wearer of a safety hat equipped with the supporting bracket of my invention snag a live wire with any portion of his hat it would be impossible for the current to shock or burn him.
I claim: 1. A safety hat comprising a visor and crown of non-conducting material, an insulating strlp riveted to said crown and bent outwardly over said rivets, bracket riveted at one end to s at the other end to said insulati a supporting aid visor and ng strip.
2. A safety hat comprising a visor and crown of non-conducting material, a curved insulating strip, metal rivets for securing one end of said strip to the crown, said rivets ter- 5 minating exteriorly 0f the crown on the inside of the curve of the strip and below the free end, and a supporting bracket secured at one end to the visor and at the other end to the free end of said strip.
3.7 A safety hat comprising a visor and a crown of non-conducting material, aninsulating strip, rivets securing said strip to the crown, said insulating strip comprising a guard overlying said rivets to prevent elec-r trical contact therewith, and a supporting bracket riveted at one end to said visor and at the other to said-strip. v
4:. A safety hatcomprisinggavisor-and; crown of, non-conducting material, aneinsulating strip;adapted to form'a support, and,
rivets securing the strip; to the crown, said strip being turned outwardly over the rivets to provide aguard therefor.
5.. Asafety; hat comprising" a visor and crown ofnon-cOnducting material, supporting means for an object adapted to be carried on the hat-and secured atone end to the visor, the otherend'of said supportingmeans comprisingv an insulating strip, metallic means securing the, insulating strip to the crown,: said strip being turned outwardly over the securing means to provide" a guard therefor. c I
Intestimony whereof, I have hereunto set my hand.
