EYEGLASS CONSTRUCTION Filed June 19, 1940 INVENTOR george E. IVZrnQ BY Patented May 5, 1942 EYEGLASS CONSTRUCTION George E. Nerney, Attleboro, Mass, assignor to Bay State Optical Company, Attleboro, Mass, a corporation of Maine Application June 19, 1940, Serial No. 341,286

2 Claims. lCl. 88-49) This invention relatesto eyeglass construction and more particularly to the mounting of nosepads.

One of the objects of this invention is to provide a nosepad mounting which will be especially strong in spots which are normally vulnerable in the usual type of the above construction. Another object is to provide a construction of the above character which is simple, thoroughly practical, and durable. Another object is to provide a construction of the above character which may be manufacturedeconomically, both from the standpoint of labor and materials used. A further object is to provide a construction of the above character which permits a nosepad mounting to be easily and quickly adjusted. A still further object is to provide a construction of the above character which provides portions which may be securely and easily gripped by tools during adjustment of a nosepad mounting' Other objects will be in part obvious and in part pointed out hereinafter.

. The invention accordingly consists in the features of construction, combinations of elements, and arrangements of parts as will be exemplified in the structure to be hereinafter described, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawing in which is shown one of the various possible embodiments of my invention,

Figure 1 is a fragmentary front elevation of a portion of a pair of eyeglasses in position upon the nose of a wearer;

Figure 2 is a horizontal section taken on the line 22 of Figure 1;

Figure 3 is a prospective'view on an enlarged scale of the nosepad and nosepad mounting arm shown in Figures 1 and 2;

Figure 4 is a rear elevation of the nosepad construction shown in Figure 3;

Figure 5 is a top plan view of the nosepad construction shown in Figure 3; and

Figure 6 is a side elevation of the construction shown in Figure 3.

ill

the wearer, noseguards should contact the sidesof the nose firmly. Thus, each nosepad is adjusted to accurately fit the face of the wearer, and the surface upon which the nosepad rests varies inthree directionsnamely, vertically,

horizontally, and diagonally therebetween. In the past, difficulty has been experienced in making a nosepad mounting which may be easily and properly adjusted to allow for these variations. A further difliculty lies in the fact that it is difificult for the retailer to obtain a secure grip with his tools upon the nosepad mounting in making the necessary adjustments. Furthermore, such failure to obtain a proper grip often results in excessive strains being placed upon portions of the nosepad ormounting therefore, with resultant damage thereto. Accordingly, it is another object ofthis invention to provide a nosepad mounting adapted to overcome the above mentioned difficulties, as Well as many others.

It might here be noted that reference hereinafter to 'an outward direction signifies a direction to the right or the left of the center of the bridge of an eyeglass frame in the direction of the temple, while the term inward denotes a direction toward the center of the bridge from one of the temples. A rearward direction refers to a direction toward the face of a wearer, whereas the term forward denotes the opposite direction thereto. An upward direction refers to a direction upwardly from the facev of a wearer, while a downward direction is opposite thereto.

Referring now to the drawing in detail, there is shown in Figures 1 and 2 the bridge portion of an eyeglass frame, including a bridge 10secured to a pair of rims H and I2 which mount lenses l3 and I l. Extending rearwardly from each of the connecting points between rims H and I2 and bridge I0 is a noseguard mounting arm. These arms, generallyindicated at l5 and i6, carry nosepads I1 and I8 respectively. As nosepad mounting arms l5 and I6 are substan tially similar in construction, being merely of reversed configuration so that they can provide support on the right and left side of a face, the description hereinbelow is limited to arm l5 which'suppo'rts nosepad l'l. Y

As best shown in Figures 3 and 6, arm 15 has one end l9 secured to rim H and the other end 26 secured to nosepad H and the arm includes three sectionsnamely, a rearwardly extending section H, a downwardly extending section 22, and a forwardly extending section 23; The rearwardly extending section 2| has a substantially straight portion which extends rearwardly from its point of connection to the rim substantially to the edge of the upper end of nosepad I! (Figv ure At this point section 2| curves outwardly and thence follows a semi-circular path terminating at a point which lies adjacent the rearward edge of the upper portion of the nosepad. As shown best in Figures 5 and 6, all portions of this section lie in. a substantially flat horizontal plane, so that it may be securely gripped by a pair of pliers, as will be more fully described hereinafter.

' Referring now to Figures 4 and 6, section '22 extends downwardly from the rearwardly extending section 2| at substantially a right angle thereto and follows the outer surface of the nosepad adjacent the edge thereof, terminating at a point adjacent the edge of the center portionof the nosepad. Section 23 connects to the down, wardly extending section 22 at this point and extends forwardly across the center of the nosepad terminating adjacent the forward edge thereof.

The nosepad is connected to the ,last mentioned section by means of the connection disclosed in the United States Patent to Person, No. 2,209,827, which issued July 30, 1940. An open-ended boxshaped member '25 is mounted transversely on the nosepad and is adapted to receive the end of section 23 which is reduced in size as indicated by the dotted line 60 (Figure 5) A tongue 28 on member 25 is bent into a notch on the end of section 23 connecting the nosepad to the arm. This securely mounts the nosepad on arm I5, and due to the fact that the arm is slightly smaller than the opening extending through box-shaped member 25, limited rocking motion is permitted between the arm and the nosepad.

Referring now to igure 4, it may be seen that this nosepad mounting is so constructed that adjustments of the nosepad may be easily and quickly made. In orderto make vertical adjustments or :those adjustments necessary to fit the nosepad to the vertical shape of ,a face, the rearwardly extending section 2| is grasped between the jaws 3| (Figure 4) of a pair of pliers. The curved portion of this section assures a firm grip thereon and prevents it from rotating between the jaws while adjustments are being made. The nosepad, section 22 and section 23 are then gripped between the jaws 30 of another pair of pliers. A secure grip is assured as sections 22 and 23 and member 25 lie in a single plane parallel to the flat surface of the nosepad and are all of substantially the same thickness. The vertical adjustment of the nosepad may then be varied by bending the arm 15 at point 24 to the right or the left of the nosepad as viewed in Figure 4. As sections 23 and 24 are both positioned adjacent the rear surface of nosepad I], the pliers secure a firm grip on these sections of the arm and the nosepad. This effectively prevents injurious strains from being placed on the connection between the nosepad I1 and the arm [5. f

In making adjustments to fit the nosepad to thecurved surface 33 (Figure 2) which extends between the nose and the eye of the wearer, the pliers are used in the same-positions. In this type of adjustmenttheshape of section 2| also affords a secure grip on this portion of-arm l5. To make the adjustment, the pliers having jaws 30 are twisted so that the nosepad rotates with section 22 as a center. By this action proper horizontal adjustments may be attained, andas the jaws 30 extend across section 23, this section acts as a lever on section 22 to twist it into the proper position with respect to section 2|. Diagonal adjustments are also made with the pliers in the positions shown in Figure 4, and arm 22 is bent about point 24 to the right and left of the position shown in Figure 6. As in vertical adjustment, the positioning of the pliers and the design of the sections prevent damage to the connection between the nosepad and the arm durin these last two adjustments.

Thus all of the required adjustments may be easily and quickly. made by the retailer. Furthermore, the arm has been so designed that the pliers may secure a firm grip thereon to make these adjustments without fear of damage to the connection between the nosepad and the mounting arm.

Accordingly, it will be seen that I have provided an efficient and thoroughly practical construction, in which the several'objects hereinabove set forth, in addition to many others, have been successfully accomplished.

As many possible embodiments may be mad of the above invention, and as many changes mightbe made in the embodiment above set forth, it is to be understood that all matter hereinbefore set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
