An Appliance for Preventing Sounds from Entering the Ear.
I, MABEL MARY VAUGHAN of 5" Oxford and Cambridge Mansions, Marylebone
Road, in the County of London do hereby declare the nature of this invention
to be as follows:-
My invention is for an apparatus to prevent noises and sounds unpleasant or
disturbing to the individuals sensorium reaching the tympanum by conduction
through the external auditory canal, and is particularly adapted for the use of
invalids, students &c.
The apparatus may consist of a suitable shaped spring, or compound skeleton
fan spring, which can be padded or rendered adaptable by other suitable means, to
either the vertical, parietal or occipital region (or all such regions) of the human
head. The adjustment may be made by means of slots and binding screws in the
springs, or by means of adjusting screws working through projections in said
springs, or by clamps, toggles, buckles, pins or other suitable means. Such adjust-
ments are preferably provided to the centre of all springs, as well as to the spring
carrying the deafening pad. In the compound form of the apparatus the various
springs, preferably three, would be arranged with one bolt to hold all the ends on
one side of the head. All such ends may be slotted if desired, and the centres of
all the springs may be attached to a suitable distance piece, or pieces, so as to
maintain the said springs in their respective positions longitudinally, and such
distance pieces may also be capable of adjustment. The bolt holding the ends of
the said springs may pass through a separate adjustable spring piece so guided and
formed as to give an inward pressure, and be provided with a suitably padded,
inflated, or other flexible button, pad or plug, to press upon and effectually close
the external auditory canal, either by the pressure being exerted upon the tragus,
or by closing the meatus. The said pad may be mounted on a ball and socket,
or plain hinge joint or their equivalents, or it may be fixed to the spring. The
adjustments may also be by means of coiled, or other suitable, springs attached
between the component parts of the frame springs, and the ends of the frame
springs may be suitably guided in, on or through one another to give sufficient
rigidity. Where one spring only is used as the frame, there may be attached
thereto longitudinal pieces, back and front, to maintain the spring in its vertical
position. The springs may be made of metal, wood, vulcanite, whalebone, celluloid
or other suitable substance.

I, MABEL MARY VAUGHAN of 5º Oxford and Cambridge Mansions, Marylebone
Road, in the County of London do hereby declare the nature of this invention and
in what manner the same is. to be performed, to be particularly described and
ascertained in and by the following statement :-
My invention is for an apparatus to prevent noises and sounds unpleasant or
disturbing to the individuals sensorium reaching the tympanium by conduction
through the external auditory canal, and is particularly adapted for the use of
invalids, students etc.
That my invention may be more readily understood I have attached hereto a
sheet of drawings showing different forms of the apparatus, in which similar letters
refer to similar parts.
The apparatus may consist of a suitably shaped spring as A in Figs. 1, 2, 3 & 4,
or compound skeleton fan spring as A A A in Fig. 5, which can be padded or
rendered adaptable by other suitable means, to either the vertical, parietal or
occipital region, (or all such regions) of the human head. The adjustment may
be made by means of slots and binding screws in the spring A, as at B in Figs. 4, 5,
6, & 7; or by means of adjusting screws working through projections on said
springs, as at C in Figs. 1, 2, 3 & 5, or by clamps, toggles, buckles, pins or other
suitable means.
Such adjustments are preferably provided to the centre of all the springs, as
well as to the spring carrying the deafening pad D. In the compound form of the
apparatus the various springs A. (Fig. 5) preferably three, would be arranged with
one bolt to hold all the ends on one side of the head, as shown. All such ends
inay be slotted if desired, and the centres of all the springs may be attached to a
suitable distance piece E, or picces, so as to maintain the said springs in their
respective positions longitudinally, and such distance pieces may also be capable
of adjustment. The bolt holding the said springs may pass through a separate
adjustable spring piece F (Figs. 6 & 7) so guided and formed as to give an inward
pressure, and be provided with a suitable padded, inflated, or other flexible button,
pad or plug, D, to press upon and effectually close the external auditory canal,
either by the pressure being exerted upon the tragus, or by closing the meatus, or
covering the ear. The said pad may be mounted on a ball and socket or plain
hinge joint, or their equivalents, or it may be fixed to the springs A or B. The
pad for covering the ear is preferably made as shown in Figs. 8, 9, & 10, a suitable
inflated flexible tube G being attached to a flexible piece or plate with a star shaped
spring piece, H, which is fixed to the spring A by a screw or rivet, or joint at I.
The tube G will bear on the side of the head and the cavity at H (Fig. 9) will
be made large and deep enough to contain the external ear. With a pad of this
form the spring A may simply lay on the head, back or breast, so long as it exerts
sufficient pressure upon the pads.
The various adjustments may also be by means of coiled, or other suitable
springs, attached between the component parts of the frame springs, and the ends
of the frame springs may be suitably guided in, on or through one another to give
sufficient rigidity, as shown.
Where one spring only is used as the frame A (Figs. 1 & 2.) there may be attached
thereto a longitudinal piece (or pieces) E, back and front, to maintain the said
spring A in its vertical position. The springs may be made of metal, wood,
vulcanite whalebone, celluloid or other suitable substance.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is,
1. In appliances for preventing sounds from entering the ear the single or com-
pound spring frames A with or without adjustment and carrying pads D as herein
described.
2. In appliances for preventing sounds entering the ear, the adjustable spring
piece F as described with reference to Figs. 6 and 7.
3. In appliances for preventing sounds from entering the ear, the pad D consisting
of a flexible inflated tubular piece G and plate or spring H, as described with
reference to Figs. 8, 9, & 10.
