SPRING-GUARD FOR EYEGLASSES.

SPECIFICATION for'niing part of Letters Patent No. 650,721, dated May 29, 1900.

Application filed April 14, 1900. Serial No. 12,794. (No model.)

To all whom it may concern.-

Be it known that I, ADELABD HUFAULT, a citizen of the Dominion of Canada, residing at Southbridge, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Spring-Guard Eyeglasses, of which the following, together with the accompanying drawings, is a specification sufticiently full, clear, and exact to enable persons skilled in the art to which this invention appertains to make and use the same.

My invention consists in a hanger of the peculiar construction shown and in its combination with the guard, the spring, and the eye-frame posts,as illustrated in the drawingswherein-- Figure 1 represents a front view of an eyeglass-frame embodying my improvement. Fig. 2 represents, on an enlarged scale, a sectional View of one of the guards and hangers, showing the construction in detail. Fig. 3 represents a top view of the same, and Fig. 4 represents the blank or form of the hanger separate from other parts.

Referring to the drawings, A indicates the eye-frames, having the posts B fixed thereon. 0 indicates the spring, and D D indicate the spring-guards, attached at their lower ends to lugs a, fixed on the respective eye-frames. All of the above-indicated parts are of wellknown construction.

The spring-guard is provided at its movable end with an outwardly-projecting top portion d longitudinally slotted, as at 2.

My improved hanger F is composed of an upper plate portion 3 and lower plate portion 5, laid approximately parallel to each other with an intervening space or guideway G, within which the slotted top 61 of the guard slides. The two portions 3 and 5 of the hanger are integrally united by a narrow loop bend 6, that passes through the slot 2 of the guardtop d, and said upper and lower plate portions both extend into the head of the post B, where they are secured, with the end of the spring 0 embraced between them, by means of the screw I, which passes through the upper part 3 of the hanger, through the spring end, and through the lower plate portion 5 of the hanger and screws into the post B, as best shown in Fig. 2.

The hanger F is made from a blank (see Fig. 4) of straight fiat Wire stock, its central part laterally reduced by impressed side recesses 7 to form the narrow neck 6, and holes 8 are formed through its two ends, as indicated. This prepared blank is then folded together uniformly, with the fold-loop at the narrow neck portion and the two plate portions 3 and 5 laid parallel to each other, with the space G intervening. The several parts are then assembled by passing one end of the hanger through the slot 2 in the guardtop 01, turning its slot on the loop bend 6, so as to bring the guard-top '01 into the space Gr between the hanger-plates. The end of the lower plate 5 of the hanger F is then seated in the post B, the end of the spring 0 inserted between the plates 5 and 3, and the screw I inserted and tightened, uniting the parts as illustrated and above described. 7

As advantages attained by my invention it may be noted that by the improvement set forth I produce a spring guard eyeglass- -frame wherein the hanger F protects the guard-top d,while permitting the proper yielding action of the guards. The hanger being integrally formed with an upper part 3 and lower part 5, which are both rigidly secured in the post B, is compact and very efiicient and rigid and prevents the slotted top of the guard from becoming bent or twisted, (a common annoyance with the ordinary constructions,) while it gives a smooth exterior and neat finish, also doing away with hook points or projections liable to catch in the clothing or when inserting or removing the eyeglasses into or from a pocket or case. The hanger being more rigid, the eyeglasses are less shaky on the nose and the hanger and guards are less liable to become displaced and the glasses broken than are those having the usual construction. Also for gold-filled work the improvement is desirable, as the construction offers no exposure by cut edges of the interior metal of the gold-filled plate or stock. It will be understood that I do not broadly claim a spring-guard for an eyeglass-frame. What I claim as of my invention, and desire to secure by Letters Patent, is

1. In spring-guard eyeglasses, the hanger F consisting of a single piece of fiat wire stock laterally reduced at its 1nid-length and folded at its reduced neck, forming two approximately-parallel portions 3 and 5,disposed with a narrow intervening space G, the upper and lower portions of said hanger both extending into the post, and the ends there seated and rigidly secured, for the purpose set forth.

2. In a spring-guard eyeglass, in combination with the eye-frame posts, the spring, and spring-guards each havingits lower end connected to the eye-frame and its upper end provided with a longitudinally-slotted top; the hangers respectively comprising upper and lower plate portions disposed with intervening space for the reception of the guardtop and united by a loop-bend that passes through the slot in said guard top, the outer ends of said upper and lower portions of the hanger being perforated and both secured in the eye-post, with the end of the spring interposed between them, bya fastening-screw ADELARD IHJ'FAU L'l.
