SPECIFICATION forming part of Letters Patent N 0. 651,989, dated June 19, 1900.
Application iiled April 7, 1900. Serial IIo. 11,923. (No model.)
To all whom, it may cole/cern:
Be it known that I, LEON A. DUPAUL, a citizen of the United St-ates, residing at Southbridge, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Eyeglasses, of which the following, together with the accompanyingdrawingsnsaspecificationsufcientlyfull, clear, and exact to enable persons skilled in Io the art to which this invention appertains to make and use the same.
My invention rdates to the construction of an eyeglass-guard with an arm having lips or flanges on the sides of its attaching-head that I5 overlock upon the sides or edges of the post and to the manner of combining said guard with they spring and eye-supporting post, as hereinafter more fully explained, the object being to afford a construction Vin which the 2o parts are locked together by the head of the guard in a peculiar manner that will give a secure rigid joint and prevent the loosening of the joint-screw by the shaking of the parts when in use; also, to provide an attachment that will afford a neat finish andwhich may be successfully employed for gold-filled stockforms as aiding non-exposure of interior material. These objects l attain by the peculiar construction and manner of attachment spe 3o cifically pointed out in the following detail description, and illustrated in the accompanying drawings, wherein-Y Figure 1 is a front View of an eyeglass-frame embodying my invention. Fig. 2 is a central 3 5 vertical section. Fig. 3 is a perspective view of the post; Fig. 4, an end view o f the eyeloop and post; Fig. 5, a back view of the guard; Fig. 6, a perspective view of the guard Fig. 7, a vertical section through the post and attaching-joint; and Fig. 8, a top view of the attaching-joint, the spring and eye-wire b'eing in section. The views Figs. 3, 6, 7, and 8 are drawn to enlarged scale to more clearly show the relation of the parts in detail.
In referring to the drawings, a denotes the post, which is attached to the eye-wire b. Said post is in accordance with my invention formed with a dat rectangular narrow head portion 2, having a plain flat seat-face with 5o parallel or straight edges at the sides 3. The
`support thereon.
Width of the post-head is approximately the same as the width of the eyeglass-spring c.
I construct the arm (Z of the guard D with laterally-projecting fianges or lips 5 along the vertical edges of the attaching portion or head, as shown, (see Figs. 5, 6, and 8,) and with a flat seat-surface 4: between said lips 5 corresponding to the width of the spring c. The outward projection of the lip-liangcs 5 is approximately equal to the thickness or' the 6o spring plus the thickness of the post-head,
Vand said flanges are adapted to shut over the edges ot' the post `and form an overlocking The inner faces of the lips 5 may be at right angles to the surface 4, but 65 are best made slightly inclined, as shown in Fig. S. Au opening 6 for the screw f is formed through the center of the guard-arm head, and a threaded hole is formed in the center of the post a, into which the screw fits. 7o The spring c is madewith plain nat ends having holes therethrough for the binder-screws f. When the parts are assembled, the end of the springe rests upon the end face of the posta and the guard-attaching head d seats against the spring and its lips 5 firmly embrace the opposite parallel edges of the spring and post-head, the guardhhead fitting as a finishing-cap over the joint parts, as indicated, and the screw f when screwed in binds the 8o parts axially to the post a, thus making a secure, rigid, neat, and simple attachment, in which the parts are so confined by the overmatching guard-head lips that the shaking of the frame does not tend to loosen the screw Vor create looseness in the joint.
Among the advantages attained by this improved construction may be mentioned the following: The posts can be made of smallern sized stock than ordinarily required and the 9o groove milling across their ends is obviated. The lips 5 aord an increased length of side bearing-surface and a more secure and firm support for the spring. and guard upon the post, and the screw is not liable to become loose when the glasses are in use. A smaller` joint is formed and a neater finish produced at the junction of the spring and about the post. The posts and guard-heads can be diestruck to finished shape, thus rendering their Ioo manufacture comparatively simple and neX- pensive` from any suitable material or metal. The external joint finish surface being formed mainly -by the overmatching guardarm head and its side lips can be lproduced with facility from gold-filled stock, as wellas from other stock, since the structural form s ubserves the preservation ofthe gold surface and non-exposure of interior illing metal.
For eyeglass-mountings without eye-f rames b the foot of the post a may be made With the glass receiving and holding jaws such as arev usuali-y employed for attaching-posts tothe glass lenses in eyeglasses.
Whatl claim as of my invention, and desire to secure by Letters Patent, is-
1. An eyeglass structure provided with an eye-connecting post having -a iiat seat-face with parallel side edges, a guard having its arm or attaching ,head provided with lipflanges formed on the sides thereof and adapt'- ed to overlook and embrace the edges of the vspring and `.post -headg and the fasteningscrew arrangedthrough said guard-arm 'and threaded into the post.
2, In an eyeglass, the combination of -a spring having a plain perforated end, an eyepost having a flat spring-seating face approximately corresponding to the Width of the spring, with side bearing edges, as shown, a
' guard having its arm or attaching-head providedwith lips or side flanges with beveled inner surfaces, adapted to fit over and lock uponthe opposite ed ges of the spring and post, and the fasteningscrew arranged through said guard-head, and axially threaded in said post. Y 1
