EYEGLASSES.

SPECIFICATION forming part of Letters Patent No. 659,404, dated October 9, 1966. Application filed. October 20, 1899. Serial No. 734,157. (No model.-

To all whom, it may concern:

Be it knownthat I, ADAM LIGHT, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Eyeglasses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying draw ings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in mountings for eyeglasses or spectacles, and more especially to a novel construction of strap or jaw and post to be used in connection with the spring and nose-guard of the glasses.

The invention has for its principal object to provide a mounting for eyeglassesor spectacles which can readily be secured in position to the lenses or glasses without the danger of breaking or cracking the same by the pressure of the parts of the strap against the faces of the lens while being secured in position.

A further object of this invention is to provide a novel means of securing the ends of the strap to the lens in such a manner as to remove all strain from the lens and prevent cracking or breaking of the same.

A further object of the invention is to provide a pivotally-attached strap and a separate post having supports or legs made of spring metal to prod uce greater resiliencyof the parts and to provide a guard which when in position on the nose will result in greater comfort and ease to the wearer.

The invention therefore consists in the general construction of a mounting for eyeglasses or spectacles hereinafter set forth, as well as in the novel arrangements and details of the construction thereof, all of which will be more fully described in the accompanying specification and finally embodied in the clauses of the claim.

The invention'is clearly illustrated in the accompanying drawings, in which Figure l is a perspective view of a pair of eyeglasses and a mounting therefor embodying-the principles of my present invention. Fig. 2 represents a face view, on an enlarged online x in said Fig. 2. Fig. 4 is a perspective view of the strap, and Fig. 5 is a similar view of the form of post employed in connec tion with my invention.

' Figs. 6 and 7 are perspective views of modified forms of posts, but which are all made according to the principles of this invention.

Similar letters of reference are employed in all of the said above-described views to indicate corresponding parts.

In the said drawings, A indicates the coinplete mounting, which comprises the usual form of spring I), connected at its free ends v with the posts 0 and straps d to the glasses or lenses a. As will be seen from an inspec tion of Figs. 1, 2, and 3, each lens a is provided with a perforation a, in which is preferably arranged a piece of flexible tubing a of rubber or other suitable material, and a represents anordinary pin or screw in said tubing for securing the strap d in position.

Each strap d comprises a box portion (1, in

- which there is a screw-threaded hole CF, and

has a pair of arms (1 which are to be ar ranged on the opposite faces of the lens, and have perforations or holes d to be placed directly over the perforationsa in the lens a, whereby the strap can be pivotallysecured to the lens by means of the pin or screw a above mentioned, which is passedthrough said holes d? in the'strap d and through the tube a and. secured in place, substantially as illustrated in Fig.3. As shown in said figure, the tube a is slightly longer than'the thickness of the glass or lens a, whereby when the screw a is screwed up tight in the holes of the arms (1 of the straps cl the ends a of said tubing a will be compressed between the surfaces of the lens and the inner surfaces of the said arms d thereby. removing all undue pressure and strain from the glass to prevent cracking or breaking of the same, but still permit the strap 01 to be operatively and pivotally secured to the lens. The strap (1 also has its boX portion d provided with oppositely-arranged and outwardly-extending lugs or projections d One form of postc, such as I prefer to employ, is illustrated more particularly in Figs.

1, 2, 3, and 5, and it consists, essentially, of a cap or plate 0', which is provided with a hole or perforation c and has an arrangement of iongitudinally-disposed shoulders or projections 0 which with the said cap or plate a will form a box-like portion of the post 0. These shoulders or projections c are made parallel, or approximately so, and near their junctions with the said cap or plate 0' the latter is curved to form a pair of grooves or channels 0 and c in the upper surface of the cap or plate and with a longitudinallydisposed groove or channel 0 in the lower surface of the plate, as clearly illustrated in said Fig. 5. Into the channels or grooves c and c are placed the end portions 6 of yielding strap-pieces 6, preferably made of springwire, said pieces being bent to form the downwardly-projecting parts 6 and the outwardly-extending parts 6 the latter being connected, as at 6 and the complete pieces 6 forming suitably-bent supports of the post 0 at opposite ends of the cap or plate 0 of said post.

In the construction illustrated in Fig. 5 of the drawings the ends (2 of the yielding strap-pieces e are simply laid in the grooves or channels 0 and c and by means of pressure and without the use of solder these various parts are closed down tight and the parts thereby securely fastened together to form a complete post; but it will be understood that the ends (2 of the strap-pieces e may be secured to said plate or cap 0 by means of solder. If desired, the ends 6' of the strap-pieces 6 may be secured directly to the edges 0 of the cap or plate 0 by means of solder or in any other usual manner, as indicated in Fig. 6, or I may make the plate or cap 0 and the supports in one integral piece, as indicated in Fig. 7, by providing the cap or plate 0 at its ends with the sheet-metal portions 0 which are bent downwardly, as at c, and then outwardly, as at c to form suitable supports, as clearly illustrated in said Fig. 7. To secure the ends I) of the spring Z) and the posts d and straps together to provide the complete mounting A, the straps d are pivotally attached in position, one to each lens or glass at, in the manner above set forth and as represented in the several figures of the drawings. I next place the cap or plate a of one of the posts 0 against the box portion d of the strap d, so that it will extend partly into the central groove or recess 0 in the under surface of the cap or plate a, with the curved lugs or projections d of the box portion d also extending into said groove or recess 0 and the extreme free end portions of said lugs or projections hugging the edges of the said cap or plate 0, as indicated in dotted outline in Fig. 2 of the drawings. The perforated endb' of the spring I) is then placed upon the outer surface of the cap or plate 0, between the longitudinal shoulders or projections 0 Upon the end of the spring Z) and also between said shoulders movement of the spring.

or projections c is placed the perforated end f of a nose-guard f, all of said parts being securely connected with the box portion 01' of the strap (1 and with the ends of the supports e resting against the edges of the glass or lens a, as illustrated, by the use of a screw or pin'f in the manner shown and as will be fully understood from an inspect-ion of Figs. 1, 2, and

Of course it will be understood that the posts and straps at each endof the spring I) for securing both lenses or glasses a to the mounting A are alike.

By my novel construction and arrangement of the parts as hereinabove described I have found that when the assembled parts have been securely connected by the screw f the parts 6' and e of the yielding strap 9 will .move in an outward direction, firmly gripping the edge of the lens. In this manner these parts substantially prevent pivotal By the arrangement of the lugs d connected with the strap d, a cushion is provided to permit the screw f to be fully screwed up and the several parts to be tightly drawn together without the least danger of cracking or breaking the lens. At the same time all undue strain is removed from the lens at its point of con- ,nection with the pin a thereby allowing for proper expansion and contraction of the lenses.

The many advantages derived from my present construction of mounting for eyeglasses or spectacleswill be evident from the above description; but the principal features of myinvention are the adaptability of readily and easily attaching the straps to the lens without the least danger of cracking or breaking the glass by the strain due to great pressure between the various parts as heretofore made, and, furthermore,to loosely connect the arms of the strap with the lens at its point of pivotal connection, thereby permitting the strap-pieces connected with the post during the assembling of the various parts to yield and readily adapt themselves to the curved edge of the lens or glass and to provide an eyeglass-mounting which has a greater resiliency due to this arrangement of these yieldingstrap-pieces between the mounting and the lenses or glass at their points of attachment. Furthermore, by the arrangement of the longitudinally-arranged groove or channel 0 in the under surface of the cap or plate 0 of the post 0 any lateral movement between the said plate or cap and the box portion d of the strap d is successfully overcome and a better and more positive fastening has been produced.

I am aware that several changes may be made in the various arrangements and combinations of the parts comprising my novel form of guard-mounting, as well as in the details of the construction thereof, without departing from the scope of my present invention. Hence I do not limit my invention to the exact arrangements and combinations of the parts as herein described and illustrated in the accompanying drawings, nor do I confine myself to the exact details of the construction of such parts.
