INVENTOR WILL/AM A. GUNN/NG' F/GE - ATTORNEYS 3o. ophthalmic 'mountin s embodyin to spirit of m i to tional view,

"UNITED STATES.

TION' OF- MASSACHUSETTS.

To all whom it may convent:

Be it known that 1, WILLIAM. A. Gun-- a citizen of the United States, residin the county of Worces- NING,

- ing at Southbridge,

ter and State of Massachusetts, have invented certain new and useful Improvements in Ophthalmic Mountings, of which the following is, a specification.

. This invention relates to improvements in ophthalmic mountings and in the process of producing such mountings,

One of the principal objects of the presform in'which they are produced and resist any variation therefrom,

in place of the partsbeing bent into such position against animtial'set in some other position, as has been the case imprior art. constructipns of a similar general appearance,

' A further; object of the present invention is the provision of a process of constructing both metallic and non-meta 'c parts, an in which the metallic parts shall be initiall formed in position within the non-meta 'c parts and may be concealed as desired by the said at non-metallic material.

Other objects and advantages of my improved process should be apparent by reference to the following specification taken in connection with the accompanying drawto huge, and it will be understood that l may make any=modifications in the specific details of construction shown and described within the scope of the appended claims without departmg from or exceeding the invention.

type of frame produced in accordance with my invention.

Figure V represents a plan view thereof.

Figure VI represents a sectional view as on the line VI-VI, of Figure V.

Prior to my invention it has been customary in the formation of ophthalmic mountings from what is known as composition material, to stamp or out the frames from sheet material and to subsequently bend up the bridge, end piece and other portions into desiredform. Certain dificulty has here been experienced due to the fact that while the material employed is such as can be softened under the influence of heat, or the like, it'has the peculiar property that although supposedly set in its new form, it will, due to climatic conditions or other heat and time efit'ects, tend to resume its original state or flat sheet form unless it is in some way held or secured thereagainst.

' It is, therefore, the purpose of my invention to provide a sti ucture in which the initial set will be in the final form of the mounting so that there will be notendency for the same to vary or alter its shape under normal or abnormal conditions. In

the accomplishment of this result I make,

use of the pair of die members ,1 and 2. These members, it is to be noted, have therebetweenthe communicating recesses or cavities arranged in complementary position soas to suitably enclosea space of the. size and sha e of a completed ophthalmic mounting, an in addition have one or more receivmg passages 3 communicating with the frame forming configurations 4.

Itis the urpose of my invention to take the materia for forming the'frame direct in liquid form, either as cellulose composition material", henol condensation products, or other material, which is pressed or forced through the aperture? between the die members 1 and 2, which she e and mold it into its completed form. his may be of any desired configuration, as shown in Figure 111 and] following, comprising a bridge portion 5 having integral depending nose bearing members 6, the lens receiving rims 7 provided with the lens grooves 8 and the end pieces 9, which are rearwardly curved or extended, lit is to be Figure lllll, havashown ltlll seats or a these" end piece members 9 as bending backward at right angles to the body of the frame and as having embedded therein the metallic anchors 10 provided with stems 11 terminating in the pivot ears 12, these members being suitably held in position within the dies, and the material holding the frame being forced therearound to securely interlock therewith and render the member an integral part of the frame. The additional advantage here accomplished is that not only is this end piece member 12 which serves to carry the pivot 13 for the temple member 14 securely embedded and interlocked with the end piece, but in addition the material of the end piece is formed around the pivot eye at the upper and. lower portions to more clearly conceal this pivot ear and at the same time to provide an increased thickness of material so that a larger and heavier pivot ear may be employed than it has been possible to employ in concealed relation when the frame was bent up or formed from sheet stock.

I claim:

1. The process of producing a non-metallic.ophthalmic frame consisting in forming dies having the necessary configurations, and forcing the frame material in liquid form between the dies to produce the finished article.

2. The process of producing a composition frame having integral non-bearing portions and rearwardly bent end piece members consisting in molding the frame as an entirety from liquid material.

3. The process of producing a composition ophthalmic frame consisting of placing metallic reinforcements for the frame within a mold, and then forcing a liquid cellulose composition material into the mold,-

then allowing the molded composition to set, whereby the metallic reinforcements will be carried by the frame.

4. The processof producing a reinforced non-metallic spectacle frame consisting in preparing shaping dies having metallic reinforcement steadying portions, and forcing liquid composition material between the dies and around the metallic reinforcements as held thereby.

5. The process of producing a composition ophthalmic mounting consisting in molding fluid composition into the form of a spectacle frame. having lens receivingrims and integral depending nose engaging portions and a bridge connecting the rims and nose engaging portions of opposite aides. of the mountmg.

6. The process of producing a composition ophthalmic mountin consisting in molding fluid composition mto the form of a spectacle frame having lens receiving rims and integral depending nose engaging portions and a bridge connecting the rims and nose engaging portions of op ite sides of the mounting, each of said rims being formed with an end piece outer side extending at rig plane of the adjacent rim.

7. The process of producing a composition ophthalmic mountin consisting in t angles to the projection at its molding fluid composition mto the form of a a spectacle frame having lens receiving rims and integral depending nose engaging portions, and a bri ge connecting the rims and nose engaging portions of opposite sides of a the mounting, each. of said rims being formed with an end piece rojection at its outer side extending at right angles to the plane of the adjacent rim, said end piece pprtion having a metallic hinge joint memr embedded therein while the material was i in fluid condition.

8. The process of producing a reinforced non metallic ophthalmic mounting consist ing in preparing die sections having recesses to facilitate the formation of the eye rims, bridge and end pieces, placing hinge connections in the end piece recesses of the molds, and then forcing a liquid cellulose
