HILTON r. WILLIAMS, or six-Louis, MISSOURI.

HOLDER FOB AUDITORY DEVICES.

Specification of Letters Patent.

Patented Mar. 11, 1919.

Application filed October 21, 1918. Serial N 0. 259,022.

To all whom it may concern:

Be it known that I, MILTON F. WILLIAMS, a citizen of the United States, and residing at St. Louis, State of Missouri, have invented certain new and useful Improve ments in Holders for Auditor Devices, of which the following is a speci cation.

This invention relates to certain new and useful improvements in holders for auditory devices, the peculiarities of which will be hereinafter described and claimed.

The main object of my invention is to provide means for holding up the fork of an auditory device when in use; another object is to provide means for holding the auditory tips in proper alinement for entering the ears of the user and prevent them from turning after insertion.

In the accompanying drawing on which like reference letters indicate corresponding parts, Figure 1 represents a holder embodying my invention and illustrating its use. Fig. 2, a detail rear view of the same, partly in section; and Fig. 3, a plan view of the same device.

In the use of a telephone with an auditory device for increaslng the sound, an ordinary telephone receiver A is set on a microphone block B, connected by a flexible auditory tube with a fork C, having car tips D adapted for insertion in the ear passages of the user. The fork hangs from the ears and ordinarily lies on the breast or in front of the chin. The fork has a spring tendency inward, and the ear tips D tend to turn aside from direct alinement and obstruct the passage of sound to the tympanum.

My holder comprises a spring band E having on its front end a suitable clamp F, or otherwise adapted to engage the fork C preferably at the crotch, and hold the fork substantially horizontal when the ear tips are in the ears. The band then rises .to meet the forehead where a pad G is provided, and then extends upward, over backward, and then down under the back of the head, ending near the occiput where another pad H is provided. These two pads (or these portions of the band) under the spring tendency of the band E, clamp the head between them with a yielding pressure that maintains the holder in longitudinal position on the head,and supports the fork substantially horizontal as shown in Fig. 1. The pad H, or the end of the band, presses upward under the occiput or back of the head. I have used such a band with benefit, but have found it'advisable to provide also a cross band I, spring or otherwise, having clamps J at the ends for engagement with the ends of the fork branches near the tips, so as to hold said tips from turning out of their proper alinement. This cross band is preferably fastened by its middle to the longitudinal band, as shown, and revents the earv tips from turning up or own, as they tend to do when the cross band is not used. Other means than said cross band may be provided.

I may use this cross band alone to hold up the fork without using the longitudinal spring band, but in that construction the weight of the fork makes such a leverage pressure on the ears as to be objectionable.

I claim 1. In a device of the character described the combination with a spring fork having turned-in car tips and auditory connections, of a spring band secured to the crotch of said fork at the front end, then rising to meet the forehead and curved upward, over backward and down under the back of the head where it engages the occiput with upward pressure, and a cross band secured by' its ends to said turned-in tips to prevent them turning up or down, and fasten .d y its middle to said spring band.

2. In a device of the character described, the combination with a spring fork having turned-in ear tips and auditory connections, of a flat rigid band arched over the head and having fastening means on its ends engaging said ear tips, and holding the portions of the tips that enter the ears from turning out of alinement with the ear passages when the tips are inserted therein, under the inward spring tendency of said fork.

In testimony whereof I have afiixed m signature.

MILTON F. WILLIAMS.
