rnonn PILLAB.

This invention relates to ear cushions and has particular reference to an ear cushion for attachment to an acoustical instrument in the nature of a radio rpceiving head set or telephone receivers. f

The principal object of the invention 1s the provision of a device for relieving the pressure of the ear phones against the ears of the listener which pressure is objectionable after the ear phones have been in applied position upon the head for any great period of time.

Another object is to provide a cushion or pillow for the attachment to an ear phone which will seal the phone against the cars of the listener to exclude outside noises.

A further object of the invention is to provide a cushion which may be easily and quickly attached to an ear phone and which is cheap of manufacture.

With these and other objects in view, the invention resides in certain novel construction and combination and arrangement of parts, the essential features of which are hereinafter fully described, are particularly SEE-pointed out in the appended claim, and are illustrated in the accompanying drawing, in whichz- Figure 1 is a perspective view of my invention per se. 9

Figure 2 is a side elevation ofmy improved ear cushion shown applied to the ear phones of a radio receivim head set.

Figure 3 is an enlarged vertical sectional view through one of the ear phones with my inventionapplied thereto.

Referring more particularly to the drawing, the re erence'numeral 10 designates the ear phones of a. radio receiving set and on which my invention designated in its entirety as at 11, is adapted to be attached. wherein I have shown the device as app led to a pair of head phones, it is to be un erstood that the same could also be used upon telephone receivers.

My invention 11 comprises a felt disk 12 which may be of any suiteble'thickness and shape, but it has been found desirable to use felt of about one-eighth inch in thickness, and round in plan to correspond with the shape of the ear phone on which it is used. The felt disk 11 is provided centrally with en opening 13, whic opening is adapted to stitched to the disk 14 adjacent the said piece of material havin register with the opening in the cap of the ear phone to permit free passage of the sound waves from the diaphragm of the in strument. Attaching means 14 is carried by the disk 11 and comprises a disk of sheet, rubber 15 of a size corresponding to the periphery of the disk 14, and the same is riphery as at 16. The rubber disk 15 is ormed centrally thereof with an opening 17 of a diameter slightly lltrger than the opening 13, and adapted to be expanded to receive the head 1-8 of the ear phone as clearly shown in Figures 2 and 3 of the drawing.

In attaching the device to the ear phone, the walls of the opening 17 are expanded to pass over the head on the ear phone, and by reason of the normal tendency of the walls of the openings to contract the rubber disk will adapt itself about the bead, thereby secnrely holding the device in position with the felt disk 12 against the face of the instrument.

In use, it will be seen that by reason of the disk 11 being of felt, the same will provide a yieldable surface against the ear of i the listener and thereby relieving the pressure usually provided for keeping the instrument clamped in position. The device will also seal the instrument against the ears thereby excluding all unnecessa noises.

While I have described what? deem to be the most desirable embodiment of my inven- 35- tion, it is obvious that many of the detai may be varied without in any way departing from the spirit of my invention,

'and I therefor do not limit myself to the exact details of construction herein set so forth nor to tl-llylihllg less than the whole of my invention limit only by the appended claim.

What is claimed as new is An'ear cushion comprising a felt disk having an opening arran d centrally therein, and a piece of expansib e material stitched to said felt disk adjacent the periphery thereof, an opening the opening affixed my LADISLAUS URBAN.

formed in axial alignment wit 111 said felt disk.

In testimony whereof I have signature.
