EAR PROTECTING DEVICE Filed May 22, 1942 v 2 Sheets-Sheet 2 INVENTOR. //4//X Swam /1W Patented July 27, 1943 Y rk; Iiosala Inc.,'New York This inventionrelates to an eari covering-d vice, such as anear mufi, for-protecting the ear against thermal, acoustical andnor other dis turbances. to a device for protecting the ear against cold,"
or to apply to the car an} acoustical device sushi as a telephone, and to'protect it at the same time-against undesired outside noises and sibly cold.
Heretofore, ear muffs were applied to the ear and heldinposition by meanjsof' straps necting a pair of muffs applied to'both" ears.
The same way, earphones were applied to theear-by means of springy metalstraps. Hats'or helmets were also provided flaps to cover: the-ears against-cold onto apply earphones to;
them
vices of this type are applied' to' th'e ear or cars; .It is another object of the invention to construct'earcovering or protecting devices of, the
type concemedjinsuch'a manner that tneycanj be individually each ear. It is. a fur and: independently applied ,to
held firmly in the'irposition 'onfthe car.
a is still a further object of the invention it; render the manufacture oifear 'coverin'gfor pro tecting devices inexpensive and their application to and removal from the .ear simple.
These'and other 'oblectsoi the inventiolijwllli be more clearly understood "when thespciclfl cation proceeds with reference tothe drawlng's' in which Fig. 1' shows a front view of the covering or protecting device applied to an ear, in'

It isi'a n'object of the invention to simplify the means "by" which covering or protecting-fle emplifie'd' in the drawings consists substantially of an onter cover 10;"Figs. 1', 2, 4, 5, 1 and-f3, of

When member l2 with cover HS occupiesits convex outwardly bent position shown in Fig. 8} it is apparent that considerable space isoffered inside the device between member l2 and lining ll so that it can easily be slipped over an ear 2| into a position shown in Fig. 1 and, in dotted lines, in Fig. 2. By pressing the device from the outside against the head, member I2 will be pressed from its convex position' inside, thereby pass a plane laid through its outer edge and tend to snap into its concave rein tending'fto' keep the member either inf p olded cvcri the i ffid fi cove s Jill-and l5. and fastened to outside by cover- 10 and lining H whereby an effective protection of'the ear against thermal portion near its circumference and substantially.
and, if desired, acoustical disturbances from the 4 outside is attained. It is not necessary,'however,
to press the device always against the head into 1 a position as shown inFig. 2 in full lines; satisfactory protection is also afforded in many cases when the device is left in its position and shape as shown in dotted lines on Fig; 2. o

Qtgjthe invention is simple and inexpensive in mass production.
v If it is desired,to convey to the ear acoustical waves or sounds, such as caused by a telephone, the feature according to Fig. can be used to advantage.- There an electro-magnetic telephone 22 ishfastened to the inside of cover 10, I l for instance by means of seam 23, and insulated electric wires 24 are introduced through a hollow projectiondfi of telephone 22 which snugly passes In this case also the a hole*25 in cover l0, H device may either be-applied to and left onthe ear in theconvexshape of member It as indi-. catedin dotted lines in Fig. 7,, or in a stressed position 'oft'h'at member as shown in full lines 'Ifhe cover of fabric protects the ear against disturbing noises and, if it be cold, also against the lattenlj The sounds generated by telephone 22 are directly conveyedto' the ear and there essentially undisturbed reception secured by the device 7 It will be appreciated that the covering or protecting device according to the inventionzcan be stantially comprising a full portion larger than the ear and to form an outer cover thereof, said full portion of'flexible material as exemplified by fabric and felt, another portion provided with an openingthrough which the ear can' be slipped, said other portion tightly attached to said full consisting of fibrous material as exemplified by fabric'and felt, and a fiat and substantially elastic, c-shaped member associated with said other portion, and leaving free its opening, the adjaduce their distance and bend said member, thereby rendering'i'itacapable of transverse snap action. c
