My invention- V relates to improvements portable devices to aid hearing and it. COIL? A further object of my lnventlon 1s topro videaporta-ble device adapted. for treating a. patient. normally deaf whereby mucous materia-l in the; auditory passageways; may be dislodged'thereby enabling the patient to hear.

A; turther object. is to provide a-portable device haying means for rapidly vibrating a patients head. 7 1 A further object of my invention. is to. provide a device, or the type described whichjis compact, light, and easily. carried:- tromi. place to place" A further objector-my invention is to-p150 vide a device. of the type, described which is simple in construction, durable, and eflicicnt Other objects and advantages willlappear in the following specification, and the novel features of the invention Will be particularly pointed out in the appended claims.

invention is illustrated int-he ZLGCQIIIIPQ: nying drawing, :Eorming part oi this application, in which Figure 1; is a persective view oimy device showing a container and the device, as: dis e posed in the container,

N Figured is. a, section takenalong the line 66. of Figure. 8. showing the structure by meansof which the, ends of certain rollers are supported...

In carrying, out my imlcntion I provide a container or box 11' having sides 2, ends 3.;

anda bottom 4a The side. 5. ofthe bottom 4:

is provided with a-.pad or insulation covering A pair of parallel andspaced-apart sup? porting members 7. and 8; are removably disposed within, the box If on the. pad 6' and. are held in, their spaced apartrelation by means of spacing membersQM Equally spaced-apart rollersor cylinders.- 10', .11, and 12 are trans.- versely disposed, in parallelism 'betweenthe supporting members, 7. and 8 and are mounted on. shaits; 13.

The, endportionsof'the shafts 13, "on which the cylinders 16) and" 11. are. mounted-are removabl y and, rotatably disposed in bearings 14: carried'by thesupporting members 7an'd8. The bearings-1.4 are. proyided with upright portions 15connected with the supporting members, 7 and 8, between; whichthe end portionsozfi the, shafts 1.31am disposed. Plate members 16 are fixcdly mounted on the, supporting members: Tand 8.: abut the: ends of. the shafts 1'3 or. preventing an; endthrust or longitudinal mpvementot the cylinders 10' and; 11-. with respect, to the supporting Inernbers The shiaiitlii on which the cylinder 122 is mounted. is rotatably moimtecl in bearing-members; 1'1 which are: fixedly mounted (II-I the-supportingmembers'z and 8. One end 18 of? the shaft 13- on which; the cylinder 12 is mounted ext-ends: through its: respective bearing member 17 andis operatively con- .nectedvwith-a! motor'lill disposed in thebox 1.

respective end portions. Rollers 24 are rotatably mounted on the supporting members 7 and 8 and are positioned in close proximity to the ends of the

cylinders

20 and 21 for limiting a longitudinal movement or end thrust of the cylinders.

A table 25 is provided having spaced-apart and oppositely disposed supporting members 26 which may be constructed of a resilient material such as rubber.- The supporting members 26 are disposed between

flange members

27 and 28 and are held" in vfrictional engagement therewith, the flange members 2. and 28 being fixedly connected with the table member 25, Flange. members 28 extend over the ends of the shafts 22 for preventing an end movement of the table 25 with respect to the

cylinders

20 and 21. A resilient memher or cushioning pad 29 is disposed on the table 25. The pad 29'may be made of rubber or other suitable material in the same manner as the table supporting members 26 and the pad 6. A covering 30 which may be of any suitable material such as leather or cloth is disposed overthe cushioning pad 29 and is connected with the table 25 by means of tacks 31. The bottoms 32 of the table supporting members 26 rest on the end portions 23 of the shafts 22 Opposite ends of the table 25 are provided with resilient means such as springs 33having one end connected with the table as at 34 and the other en'd'connected with an end plate 16 as at 35. The spring members .33 areprovided for holding the table supportingmembers 26 in engagement with the end portions. 23 "of "the shafts 22. The motor 19 is provided with wires 36 which may be connected with an electricplug, not

shown, for being connected with 'a source of current. V W 1 7 From the foregoing description of the va rious parts of the device, the operation there'- of may be readily understood.

Vhen itis desired that the device be operated the wires 36 are connected with a source of current whereby the motor is energized for rapidly rotating the cylinder'12. The remainder of the cylinders are also rapidly rotated by reason of being in operative engagement with the cylinders 12. All of the cylinders are made of wood or other suitable material so that when they are revolving at a high rate of speed they will transmit a vibratory effect to the table 25. I The pads 6 and 29, together with the-supporting member 26, are made of a suitable cushioning material for the purpose. of softening the vibrations of the rapidly rotating cylinders. WVhen the cylinders are rotating, a side of the patients head may be positioned inengagement with the upholstering 30 of the table 25 whereby the vibratory motions of-the table may be communicated to. the patientss head for dislodging mucous substances in the auditory passageways for" permitting "sound waves to penetrate to the eardrum whereby the patient may be enabled to hear.
