1 Claim. (Cl. 88-'-48) This invention relates to an eyeglass construction, and has for its purpose to afford a form of nose pad that readily adjusts itself to different shapes of noses, and which can be positioned at 5 the most advantageous point on any nose, irrespective of its shape.

A further purpose of the invention is to afford a shape of pad that is pleasing and inconspicuous in appearance, and which can be easily removed to reverse its position on the nose, thereby being readily adaptable to cooperate in the most efiicient way with any nose, and to be properly adjusted to a high or low bridge, and to different types of canthus.

To these and other ends, the invention consists in the construction that will appear from the following description when read in conjunction with the accompanying drawing, the novel features being pointed out in the claim following the specification.

In the drawing:

Fig. l is a. side elevation showing a preferred embodiment of the invention as applied to an eyeglass and in operative position on a nose with a high bridge;

Fig. 2 is a similar view showing a pad in reversed position on a nose with a less pronounced bridge;

Fig. 3 is a sectional view on line 3-3 of Fig. 2;

Fig. 4 is a similar view showing the initial position of the parts when removing a pad for reversing it;

Fig. 5 is a similar view showing the pad turned with relation to Figs. 3 and 4 and in its final position for removal;

Fig. 6 is a perspective view of the pad, and

Fig. 7 is a sectional view on line 'I--'l of Fig. 3.

Referring more particularly to the drawing in which like reference characters refer to the same parts throughout the several Views, the invention is here disclosed in connection with a pad supporting structure such as forms the subject matter of application Serial No. 752,617, filed November 12, 1934, and includes an arm comprising a body portion I that is suitably secured to a lens rim or lens supporting element.

The body portion l includes a loop 2 terminating in a forwardly extending portion 3, having an opening 4 therein, and an end portion 5 having an opening 6 therein, and adapted to be bent upon the forwardly extending portion 3, as shown in Fig. 3, when the pad is finally assembled.

55 The openings 4 and 6 are rectangular, conforming to the shape of the lug on. the pad, and are arranged at right angles to each other for the purpose of locking the pad in place, as will appear presently.

The pad may be constructed in various ways, and preferably includes a stiffening plate I of metal, having a lug projecting from one face thereof and including a reduced part or neck 8 and an enlarged head 9 of rectangular formation, the metal plate 1 being encased in a zylonite covering ID, as usual in this type of construction.

The pad is preferably of the shape illustrated, comprising two end portions II and 12 which are symmetrically rounded and connected on one side by a gradual convex curved edge I3 and on the other side by a sharp concave curved edge l4, affording a recess or pocket on one side intermediate the ends which are slightly wider than the central portion of the pad.

The pad is secured to the supporting arm by first inserting the enlarged head 9 through the opening 6, as shown in Fig. 5, until it reaches the position shown in Fig. 4, then turning the pad through an angle of 90, 50- that the head 9 is in position to enter the opening 4 and the pad is then forced into the opening 4, at the same time bending the end portion 5 toward the portion 3 until the parts reach the final assembled position shown in Fig. 3, in which the pad is effectively held against accidental removal.

When it is desired to remove the pad to reverse its position on the frame, the part 5 is again bent away from the portion 3, as shown in Fig. 4, the pad then turned to the position shown in Fig. 5, and the head is removed through the opening 6. Each pair of pads includes a right and left pad so that they may both be assembled on a frame to occupy either the position shown in Fig. 1 or the position shown in Fig. 2 with relation to the nose. In the first mentioned position, the convexly curved edge of the pad is nearest to the canthus and the sharp concave curved edge and recess is toward the front, whereas in the other position illustrated in Fig. 2, the sharp concave curved edge and recess is nearest to the canthus and the convexly curved edge is toward the front. The pads may be shifted from one position to the other by removing and interchanging them on the frame.

When glasses are fitted to a person having a high prominent bridge, as shown in Fig. 1, it is desirable to have the central part of the pad as close to the canthus as possible, without interference at the ends of the pad, and this result is attained by the convexly curved edge, while the narrower central portion and. the recess on the front edge of the pad reduces the possibility of excessive pressure on the nasal bone and makes it possible to obtain a firmer and more eflicient grip on the nose. When the pad is applied to a nose having a less prominent bridge, it is sometimes preferable to reverse the position of the pad, as, shown in Fig. 2, in which case the symmetrically curved ends clear the canthus but at the same time grip the nose as far back as possible and retain the frame firmly though without excessive pressure on the nasal bone.

With this arrangement of rounded symmetrically curved end portions, and a narrower portion at the center defined by a gradual convex curve on one side and a sharp concave curve on the other side, it has been found possible to fit the pad quickly and efficiently to any type of nose, maintaining a substantially uniform pressure over the entire surface of the pad without excessive pressure at any point. The form of the pad is such as to avoid interference with the canthus on any type of nose and also to relieve undue pressure on the nasal bone.

While the invention has been described with reference to a particular type of arm for supporting a pad reversibly, it is not confined to this construction, and the invention may be carried out in other ways without departing from the spirit of the improvement or the scope of the following claim.

I claim:

In an eyeglass construction including a pair of supports, a pair of nose pads each of which has a relatively narrow central portion defined by a sharp concave curve along one edge and a gradual convex curve along the opposite edge, and enlarged rounded symmetrical end portions which are wider than said central portion to afford increased bearing surfaces at the ends to compensate for the reduced bearing surface at the center, and means extending from each pad at right angles to its face and approximately midway between its edges, permitting the pads to be removably and interchangeably attached to said supports either with their concave edges or their convex edges extending toward the rear of the eyeglass.
