OPHTHALMIC MOUNTING.

Application filed March 252, 1915. Serial No. 16,069..

To all w from it may concern Be it known that I, GEORGE H. DAY, a citizen of the United States, residingat Southbridge, in the county of l/Vorcester and State of Massachusetts, have invented cer-' tain new and useful Improvements in Ophthalmic Mountings, of which the following is a specification.

My invention relates to improvements in ophthalmic mountings, and has particular reference to an improved type of mounting which may be readily collapsed to facilitate carrying of same.

A further object of my invention is the provision of an improved type of ophthalm c mounting particularly adapted for use in protection of the eye, as well as in the retention of correction lenses therebefore, which has the parts so constructed and arranged as to be capable of ready folding into mlnimum space while providing a rigid and durable construction when open.

Further objects of my invention include the simplification of the several parts and an improvement in the various details of the, construction to at one time increase the efiiciency of the device while lessening the cost of manufacture of the same, and it will 'be understood that I may make any modifications in the specific details of construction shown and described withinthe scope of the appended claims without departing from or exceeding the spirit of my invention.

Figure I represents a front view of my improved mounting with the parts in open position. Fig. II represents a top plan view thereof. FigQIII represents a plan view of the lens retaining parts in separated relation with other parts removed. Fig. IV rep- Fig. XI represents a similar view.

resents a sectional view on theline IV-IV of Fig. I. Fig. V represents a plan view of the shield member before attachment to the lens frames. Fig. VI represents a plan view of the blank for the attaching portion of the shield member. Fig. VII represents a view of a modified blank adapted to carry the temple. Fig. VIII represents a plan view of .a construction with parts in folded position. with the parts in the position shown in Fig. VIII. Fig. X represents a detail view of a modified construction of attaching member. Fig.

XII represents another modification .of at Fig. IX represents a side elevation 'taching member. Fig. XIII represents still another modification of attaching member. Fig. XIV represents a fragmentary view illustrating a modified temple attachment, and Fig. XV represents a View with the parts in folded position.

Referring to the drawings, wherein is illustrated the preferred embodiment of the invention, the numeral 1..designates the provided with interlocking earsor the like. 6 connected by a pintle 7, to facilitate ready.

folding of the bridge or lens connecting member foI'DQfid by the two portions 4.

Patented Nov. 59,1915. 7

As previously mentioned, the particular construction particularly illustrated is adapted for use as an eye protecting member. It is tobe understood, however, that the various features of construction herein described are adapted for use with any ophthalmic mounting and not merely for use in connection with a protective style of mounting.

In connection. with Fig. I particular attention is invited tothe position occupied by the temples 8, the ears or brackets 9 to 3 which the. same are pivoted being disposed at upwar ly converging angles relative to' the axial line of the frame. On account of thisnrrangement the 'temples in place of folding substantially across thelenses with the ear hooli ortions thereof depending below the mounting, necessitating distortion of the temples in placing the mounting within its ordinary case, lie in such position that the ear hooks follow substantially the curvature of the eye wires or frai'ne, while the sides of-the temples extend diagonally from the point of attachment to the top of the opposite eye wire or frame, the temples when closed thus lying substantially within themarginal limit of the mounting and r enabling the same to be put within. a very small case without anybending or distortion of the temples.

To exclude entrance of dirt or other foreign substances at the sides of my mounting.

l2 Fi .1, I have illustrated a slightly .i inoililicd constructioni017 use in pivotally attaching a, lemplo to a frame, in this form than: hcing provided a conical point 19 with a cylindrical noel; 2O terminating in the pivot car or oars 9.

Ii. modification of this idea is illnsi'i'alcil in Fig. XHL in which I have oinyloycil a hollow wciilgc shaped member l ornioil from a llatblank and with tho cylinih'ical inoinhcr 2O swivclcd in one siilo of the niwlggc, whereby the, i'cilgc Pl'CSbiLl into and lirnily i'otainocl Within the rim or .lf lillnfiby tho lion (i tho inatoi'ial ol tho 'l i'ainig Whilo {he portion 2) is frccly rotatable to m at oi tho l'cinplc as LlC- so i'orzns may he employed when 'alcrrcil, to hai'c a coinplo which may iii 1oll ilircci ly along tho axis of tho znonnliiiy; or may ho swung around at will in tho 'l'oliling ol the mounting.

In Figs. XIV and XV, I have illustrated another modification of my invention in which the flexible shield member is secured to the frame through the medium of the member 11 and parts as hitherto described. In this form of the invention, however,-in place of the temple being directly secured to the frame the same is carried by the terminus of the flexible shield member being either rigidly or loosely connected thereto as may be preferred. The advantage of this type of construction should be readily apparent by reference to Fig. XV, from which it will be seen that when the parts are folded the flexible shield member may be readily crumpled or doubled upon itself to bring one terminus of the short temple immediatelyadjacent the frame and extending in any desired direction relative thereto, while the hook curves toward the central or bridge portion of the frame forming an extremely compact readily folded or carried construction. I I claim: 1

1. In an ophthalmic mounting embodyinga non-metallic frame member, a fitting therefor, comprising a body portion having a furcated member projecting therefrom, said furcations inclosing a space therebetween and having shoulders adjacent their termini forming a partial closure for the space, whereby when the furcations are pressed into the frame the material of the frame will fill the space therebetween and look behind the shoulders toprevent accidental withdrawal of the parts therefrom.

2. In an ophthalmic mounting, the combination with a lens receiving frame, of a shield attaching frame carried thereby, said shield attaching frame comprising a 'rim having a plurality 'of ears formed at one edge thereof, certain of said ears being reversely bent to clampingly secure the shield between the rim and ears and the other ears extending substantially in line with the frame, of a fitting therefor having a substantially sharp entrance portion, a shoul-' der adjacent .the entrance portion, and a. reduced portion extending outwardly beyond the shoulder, whereby the material of the frame may be forced behind the shoulder to securely lock the entrance portion therewithin, and a fitting carried by the reduced portion exterior to the frame. 4 In an ophthalmic mounting, the combinatlon with a composition frame, of a shield therefor, and a connection between the shield and the frame, said connectiori -i:omprising means for gripping the shield and anchors for embedment in the frame.

5. An ophthalmic mounting comprising a lens frame, a shield therefor, and means en1- bedded in the frame for securing the shield thereto. Y

6. A mounting of'the character described,

comprising a lens frame, a shield therefor,

and means secured to the'shield and having portions thereof embedded in the frame to secure the shield to the frame.

7. In an eye protector, the combination with a rigid lens engaging portion and a flexible, shield, of a connecting device for said portions comprising a metallic strip having ears bent to clampingly engage one of said members and having hook-like projections piercing and engaging the other of said members to securely connect the parts.

8. An ophthalmic mounting, including a lens engaging frame, a shield, and a channel member for connecting said parts having portions of the channel squeezed to clampingly engage one of the parts and having other portions of the channel formed into projecting hook-like ears, said .ears piercing the other member and the hook engaging with said other member to securely connect the parts. In testimony whereof I aflix my signature in presence of two witnesses.
