NOSE PAD FOR EYEGLASSES Filed NOV. 1, 1934' 'INVENTOR.

A BY ATT RNEY.

Patented Dec. 10, 1935 UNITED STATES amuse PATENT OFFICE 5 Claims.

This invention relates to improvements in nose pads for eyeglasses, and more particularly to a pad comprising a shell, a nose engaging portion, and an inner tube or sac interposed between said shell and nose contacting portion and filled with any desired substance or material, such as, air, mercury, non-hardening plastic, liquid, or a pulverized solid, such as sand or any other movable material, or a self-adjusting or conformable material, such as sponge rubber.

An object of the invention is to provide an improved nose pad for eyeglasses which will comprise a shell which will be attached to the eyeglass frame, a nose engaging or contacting surface formed of rubber or celluloid, or any suitable flexible or conformable material, and an inner tube or sac positioned between the shell and nose engaging surface which will be filled with any desired liquid or substance, and finally means for varying the pressure on the sac to insure the proper pressure of the pad on the nose.

Another object of the invention is to provide a nose pad for eyeglasses having a shell for attachment to the eyeglass frame, an outer cover or shoe, and an inner tube or sac disposed therebetween, and provided with or without a valve, as desired.

Other objects will appear as the description proceeds.

In the accompanying drawing which forms a part of my application,

Figure 1 is a perspective View of my improved nose pad;

Figure 2 is a sectional view taken through the nose pad;

Figure 3 is an enlarged detail view of the nose contacting shoe of the pad;

Figure 4 is a detail view of the inner tube formed with a valve, and

Figure 5 is a detail View of the inner tube formed without a valve.

Like characters of reference are used throughout the following specification and the accompanying drawing to designate corresponding parts.

In carrying out my invention, I provide a metal shell I for my improved nose pad for eyeglasses, having a suitable attaching arm 2 for connection with the eyeglass frame (not shown). An opening 3 will be formed in the shell I, so that a valve may extend therethrough in order to fill the inner tube used with the pad. The shell I will be further provided with a peripheral bead 4.

The pad shoe or nose contacting portion 5 will be formed of rubber or celluloid, or any desired flexible material, the outer surface of which will be corrugated or roughened to provide a nonslipping contact with the side of the nose bridge when the pad is in position thereon. A peripheral lip 6 will be formed about the edge of the shoe 5, and will be adapted to engage and fasten over the peripheral bead 4 on the metal shell I.

It will be observed that I have shown and described the inner tube l, as provided with a valve 8, and also without a valve. The tube or sac 1 will be formed of rubber or any desired material, and when air or any other suitable liquid is employed, the valve 8 will be employed in filling the same. However, if mercury or sand, or any other material is used in the sac, then there will be no valve, and the material will be sealed within the sac.

A follower 9 is positioned within the shell I and contacts the tube or sac I, and is provided with an adjusting screw I 0 extending through the shell I, so that pressure may be transmitted through the sac to the nose contacting shoe when the screw is turned inwardly, to secure a firmer grip upon the surface of the nose bridge.

Summing up my invention, I have devised a nose pad for eyeglasses having a metal outer shell, and a nose contacting shoe, between which an inner tube is received, which may be compressed by means of a follower to obtain the desired grip on the surface of the nose bridge.

Many minor changes in detail of construction may be resorted to without departure from the spirit of the invention.

Having thus described my invention what I claim as new and desired to secure by Letters Patent 05 the United States is:

1. A conformable nose pad for eyeglasses having a shell, a flexible nose engaging shoe carried thereby, and a flexible inner tube between said shell and shoe.

2. A conformable nose pad for eyeglasses having a shell, a flexible nose engaging shoe carried thereby, a flexible inner tube between said shell and shoe, and means for varying the pressure in said tube.

3. A conformable nose pad for eyeglasses having a shell, a flexible nose engaging shoe carried thereby, a flexible inner tube between said shell and shoe, a fluid in said tube, and means for exerting a pressure on said tube to vary the cushioning effect of said shoe.

4. A conformable nose pad for eyeglasses having a shell, a flexible nose engaging shoe carried thereby, a flexible valved inner tube between said shell and shoe, a fluid in said tube, and means for exerting a pressure on the tube to vary the cushioning effect of said shoe.

5. A conformable nose pad for eyeglasses having a shell, a flexible nose engaging shoe car-.

ried thereby, a flexible inner tube between said shell and shoe, 2, suitable movable material in said tube, and a follower carried by said shell for engagement with the tube to vary the pressure of said shoe on the nose bridge of the 5 wearer.
