Dec. 2, 1941. G. R. WELLS I I EAR MASSAGE TREATING MACHINE Filed Jan. 13, 1941 3 Sheets-Sheet s 3/ In venior A itomey Patented Dec. 2, 1941 i QFFICE 4 Claims.

The present invention relates to new and useful improvements in ear massage-treating machines and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character which embodies power operated means for alternately and at regular predetermined intervals subjecting the ear, and surrounding area, to air pressure and suction, thereby massaging and stimulating circulation of the nerves and blood vessels in this area in addition to compressing air currents in the inner passages of the human ear.

Another important object of the invention is to provide an ear massage-treating machine of the aforementioned character comprising novel supporting means.

Other objects of the invention are to provide an ear massage-treating machine of the character described which will be comparatively simple in construction, strong, durable, highly emcient and reliable in use, compact, light in weight and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification,

taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure l is a View in side elevation of an embodiment of the device, portions of the housing being broken away in section to reveal the mechanlsrn therein.

Figure 9 is a view in horizontal section, taken substantially on the line 99 of Figure 8.

Figure 10 is a plan View looking at the head rest of the portable embodiment from the line Iii-Hi of Figure 8.

Referring now to the drawings in detail, the reference numeral 1 designates a tubular post of suitable metal. Threaded on the lower end portion of the post I is a removable cap 2. Welded or otherwise suitably secured on the cap 2 is a metallic bracket 3. Adjustably mounted on the post i is a bracket 4. The brackets 3 and 4 provide means for firmly securing the post I in position on a table or other suitable support.

Mounted for swinging movement in a horizontal plane on the upper end portion of the post I is a housing which is designated generally by the reference numeral 5, said housing being substantially oval in plan as seen in Figure 3 of the drawings. Mounted on the bottom 6 of the housing 5, in one end portion of said housing, is a bearing 1 through which the post i passes. Fixed to the top 8 of the housing 5, above the bearing 1, is a cap 9 in which the upper end portion of the post i is threadedly engaged. Thus, the housing 5 is adapted to swing on the post i. This swinging movement of the housing 5 is definitely limited by a pin it! on the post I which is operable in a recess l i in the upper portion of the bearing 7. The length of the recess H is approximately onequarter of the circumference of the bearing 1.

Mounted on the bottom 6 of the housing 5 are brackets l2 which support a platform l3 in the form of a metallic plate. Mounted on the platform l 3 is a suitable gear reduction unit M which is driven by a suitable electric motor l5. A conventional switch IS on the housing 5 controls the electric motor 15. Fixed on the driven shaft ll of the gear reduction unit it is an eccentric 18. A pin I9 projects from the eccentric I8.

Also mounted on the platform 53 is a substan tially U-shaped bracket 28. Journaled in the bracket 22 is an angular rocker arm or lever 2|. The pin I9 is engageable beneath one end portion of the rocker arm 2! for periodically actuating said rocker arm in one direction. Pivotally suspended from the other end portion of the rocker arm 2! is a rod 22 which passes slidably through an opening 23 provided therefor in the bottom 6 in the forward end portion of the housing 5.

Mounted on the lower end portion of the vertically slidable rod 22 is a collapsible cup 24 of resilient rubber or other suitable material. The rim of the cup 24 has vulcanized thereon a sponge rubber pad 25 in the form of a substantially flat ring. Fixed on the rod 22 is a finger lift 26 for manually elevating the cup 24 when desired. A suitable handle 2! is provided on the free or forward end of the housing 5 for swinging said housing on the post i.

It is thought that the operation of the machine will be readily apparent from a consideration of the foregoing. Briefly, the head of the patient is placed on one side on the table or other support and the housing 5 is swung on the post I for positioning the cup 24 over the ear to be treated. The sponge rubber pad 25 is adapted to contact the head around the ear being treated and functions as a partial seal for the cup 24. In ailments other than of the ear, such as primary mastoiditis, optical nerve strain, tonsilitis, dental nerve infection etc., the car on the side of the face affected is placed under the cup 24 as in treating an ailment of that ear. When the switch I6 is closed the electric motor I5 is energized and drives the eccentric I8 through the gear reduction unit l4. Thus, the pin i9 actuates the rocker arm 2| in a direction to move the rod 22 downwardly. In this manner the cup 24 is collapsed and the air expelled therefrom is forced into ear. When the pin l9 moves away from the rocker arm 2| the rod 22 is freed and the cup 24 slowly returns to its natural shape thereby creating a vacuum or suction in the ear. When the pin l9 again picks up the rocker arm 2| the foregoing operation is repeated. The motor [5 may be connected to any suitable source of electric current. Access to the mechanism in the housing 5 may be conveniently had through the medium of a removable plate 28 on one side of said housing.

The synchronized vibration of the power motor is transmitted by the perpendicular shaft through the rubber pressure-suction cup to the area of the ear, thereby sensitizing the nerves of that area, causing an inhancement and graduation of the bone conduction of sound vibration and usually a resultant improvement in those suffering from a progressive deafness.

Although, the ear-massage-treating machine was primarily built for treating defective ears, by tests, it has been found to be very beneficial as treatment for other ailments which occur in the area around the ear.

In the embodiment illustrated in Figures 8 to 10, inclusive, of the drawings, the reference numeral 29 designates a stand for the housing 5. The stand 29 includes a base 30 which is provided with suitable casters 3! or the like. Rising from the base 30 is a tubular post 32. Mounted on the bottom 6- f the housing and depending therefrom is a sleeve 33 which is journaled on the post 32. Referring to Figure 9 of the drawings, it will be observed that the post 32 has formed therein three circumferentially spaced notches 34. A latch 35 is pivotally mounted on the sleeve 33 and engageable selectively in the notches 34 for releasably securing the housing 5 in the desired position on the post 32.

Mounted at an intermediate point on the post 32 and projecting horizontally therefrom is a metallic arm 38. Threadedly mounted for vertical adjustment on the outer end portion of the arm 36 is a short post 39. Mounted for universal tilting adjustment on the upper end of the post 39, through the medium of a ball and socket joint 40, is a head rest 31. The head rest 31 comprises an annular sponge rubber pad 38 which serves as a cushion for the head and which accommodates the car which is not being treated. The operation of this form of the invention is substantially similar to that of the embodiment illustrated in Figures 1 to 7, inclusive, of the drawings. When the latch 35 is engaged in the intermediate notch 34, the cup 24 is directly over the head rest 31.

It is believed that the many advantages of an ear massage-treating machine constructed in accorclance with the present invention will be readily understood, particularly by those skilled in the art to which the device pertains, and although preferred embodiments are as illustrated and described, it is to be understood that further modifications and changes in the details of construction may be restorted to which will fall within the scope of the invention as claimed.

What is claimed is:
