Description

June'24. 1930. L. JAUSS 1,768,068
EAR PROTECTOR Filed Nov. 10, 1928 Patented June 24, 1930 UNITED STATES PATENT OFFICE LOUIS JAUSS, OF STUTTGART, GERMANY, ASSIGNOR TO EMIL KO GERMANY EAR PROTECTOR HL, OF CAIISTATT,
Application filed November 10, 1928. Serial No. 318,483, and in Germany September 12, 1927.
This invention relates to an ear-protector designed to protect the ears against influences of the weather without interfering with the hearing.
According to the invention the capsule of the ear protector designed to cover the shell of the ear consists of a piece of leather on the central portion of which the tanned layers on the surfaces on both sides of the leather are removed so that this portion is similar to a diaphragm of rawhide approximately of the thickness of a thin drum skin, so that it makes the sound waves arrive in the ear in almost undiminished strength.
An embodiment of the invention is illustrated by way of example in the accompanying drawing in which:
Fig. 1 shows in sideelevation two ear protectors connected by a band.
Fig. 2 shows in front elevation one protecting capsule for an ear shell,
Fig. 3 is a cross section of Fig. 2.
The ear protector 0 imitating the shape of the ear shell is made, with the diaphragm m, of one piece of leather without any metal elements.
On the central portion m the tanned leather layer is removed on both sides so that this portion is similar to a natural rawhide dia- 0 phragm approximately of the thickness of a fine drum skin. The sound waves can, owing to this diaphragm, arrive in the ear in almost undiminished strength.
The ear capsules are coated on the edge facing the head in a manner known per se by a flexible cover f or the like, and they are adapted to be attached on the head by means of a rubber band 9. 7
I claim:
An ear protector consisting of a capsule made of a single piece of leather, the tanned leather layers being removed from each side of the central portion to reduce the central portion to a thickness equivalent to a thin drum skin whereby sound waves arrive in the ear in approximately undiminished strength.
In testimony whereof I affix my signature.
LOUIS JAUSS.
