10 Claims.
This invention relates to improvements in ophthalmic mountings.
One of the principal objects of the invention is to provide an ophthalmic mounting having adjustable supporting means which may be quickly and easily adjusted to the facial requirements of different individuals.
Another object of the invention is to provide means in a rimless type mounting for removing strain created by the temples on the lenses.
Another object is to provide adjustable supports for the temples or sides of an ophthalmic mounting of the above character.

Another object is to provide resilient supports for the temples or sides of a rimless type mounting.
Another object is to provide improved means of supporting the lenses.
Another object is to provide means wherein the temples and lens supporting means are removed from the useful field of side vision.
Another object is to provide simple, efficient and economical means of forming the parts of an ophthalmic mounting, wherein the cost of ma-.
terial and assembling operations are greatly reduced.
Other objects and advantages will become apparent from the following description taken in connection with the accompanying drawing, and it will be. apparent that many changes may be made in the details of construction and arrange ment of parts without departing from the spirit of the invention as expressed in the accompanying claims. I, therefore, do not wish to be limited to the exact details shown and described as the preferred forms only have been shown by way of illustration.
Referring to the drawing:

Much difficulty has been encountered, in the past, particularly in the so-called high endpiece mountings wherein the temples are normally closer to each other than in the past when the temples were connected at the horizontal center line of the lenses, in having the temples engage with the sides of the head of the wearer. During use the temples under such conditions would cut in the flesh and cause pain and discomfort. Another difliculty in the past; in a'rimless type, mounting, was that of having the lenses break at their connections to the mountings when the temples were bent during the removal or placing of the mounting on the face. It, therefore, is a principal object of this invention to provide adjustable means whereby the temples may be ad justed relative to the sides of the head and to eliminate strain on the lenses created by bending the temples when the mounting is being removed or placed on the face.
Referring to the drawing wherein similar characters of reference denote corresponding parts throughout the several views, the device embodying the invention as shown in Figures I and III comprises a pair of lenses I connected by a bridge member 2 which is secured to the lenses by means of the lens straps or clamp members 3. The said straps or clamp members 3 may be provided with openings aligned with an opening in the lens through which a screw member may be positioned to draw the clamp members together to secure the lenses therebetween or may be secured to said lenses by a solder, cement or other connection.
The bridge member 2 is formed with a central arch portion 4 having rearwardly extending end portions 5 which are looped and turned forwardly or pad 'II is attached. The central arch portion 4 may be rigid, ductile, or resilient as desired.
Attention is directed to the fact that the bridge arch, lens and nose pad supports are adjustable independently of each other and without danger of causing one adjustment to be displaced when 5 the other is being made.
The mounting is supported on the face of the wearer by the temples or sides l2 which are pivotally attached at l3 to relatively long rearwardly extending adjustable supports ll. The
said supports II are shaped at [5 to theperipheral edges of the lenses and are attached at 21 to the lens straps or clamp members 3 or to the adjacent ends of the bridge member. The supports Il may be rigid, ductile or resilient as'deg5 sired or may have different portions thereof formed with one or more of the above characteristics. These results maybe accomplished by the proper selection and combination oi materials or by the proper treatment of said mag0 terials.
In the structure shown in Figures I and III the portion I5 is preferably formed rigid and the portion ll may be ductile or resilient as desired or may have a portion ductile and another portion resilient. The portion l5 may be resilient if desired and may be flat or grooved to fit over the peripheral edge of the lens and may be shaped to abut with said edge.
In Figures II and VIII the portion I5 is provided with a depending lip l5 substantially at the point wherein the portion ll joins with said portion ii. The lip It in use is adapted to overlie the front edge of the lens and is adapted to be held in engagement with said edge by a slight pressure caused by the portion l5. This constant urging of the lip It in engagement with the edge of the lens tends to hold the portion [5 in aligned relation with said edge during the use of the mounting.
In Fig. X there is shown a slight modification wherein instead of a single lip l6 such as shown in Fig. VIII the portion I5 is provided with spaced lips l1 and I3. The said lips are adapted to engage the front and rear faces of the lens and may be held in engagement with said edge by the member l5. as described above or may be secured to said edge by cement or other means l3. If desired the portion l5 and the upper edge of the lens may be bevelled as shown at 23 in Fig. X.
In Figures VI, VII and IX there is shown another modification whereln the portion I5 is secured adjacent its opposite ends to the upper edge ofthe lens by suitable lens straps 2| and 22. In this instance the portion l5 extends substantially the full width of the top of the lens and is provided with a sharply turned rearwardly extending temple support 23 having a temple hinge connection 24 thereon to which the temple 25 is pivotally attached. The support 23 may be rigid, ductile. or resilient asdesired or may be formed with one or more of the above characteristics.
The lens straps 2| and 22 may be provided with openings aligned with openings in the 1cm and may be secured thereto by telescoping conheating means 26, as shown in Fig. 11:, or may be secured by screws, solder, cement or other means.
The telescoping means 26 may be secured together by a threaded connection or may be united by solder, cement or other means.
In all instances the temple supports it and 23 are adapted to be adjustable sidewise, up or down and shortened or lengthened as desired to change the position and length of temple. This shortening or lengthening effect may be obtained by bending the supports it and 23 intermediate their ends.
Attention is directed to the fact that in the structures shown in Figures I to V inclusive, all strain created by the bending of the temples when the mounting is being removed or placed on the face is eliminated from the lenses as the temple supporting portions II and i5 are not connected directly to said lenses. The strain in this instance is taken up by the bridge member 2.
By making theportion IS in Figures VI and VII rigid and the arch l and temple support 23 resilient all strain on the lenses created by the bending of the temples is eliminated.
In Figures In and XII there is shown a further modification wherein the lens supporting means 21 is shaped to the contour shape of the upper peripheral edge of the lens I but is positioned in the rear of said edge so that it will be substantially invisible when the mounting is viewed from the front. The support 21 follows the rear surface of the lens about its upper peripheral edge and extends downwardly on the nasal side of said lens to form a supporting portion 23 for the guard arm 23 and guard 30. The support 21 is attached to the lens I by perforated lugs 3| each having a threaded bore which is in aligned relation with attaching openings in the lens. A connecting member such as a screw 32 having an enlarged head portion is placed in the aligned openings from the front of the lens and is threadedly connected with the threaded bore of the lugs 3|.
The support 21 is adapted to provide attaching means for the bridge 33 and the adjustable temple support 34.
In Fig. XIII there is shown a further modification which is generally similar to that shown in Fig. XI except that the lens support 35 is provided with a stud box connection 36 to which the guard 31 is interchangeably attached by the connecting screw or like means 33. The bridge 39 is attached to the lens support 35 adjacent the top of the mounting and is formed resilient so that the resiliency thereof may be used to cause the guards to grip the nose and hold the mounting on the face of the wearer. The mounting in this instance may or may not be provided with the relatively long adjustable temple supports ll as desired. The support 35 is connected to the lens I by the connecting lugs 40 in a manner similar to that set forth in the structure shown in Figures XI and XE.
From the foregoing description it will be seen that I have provided simple, eflicient and economical means of accomplishing all of theobjects and advantages of the invention, particularly. that of providing adjustable supports for the temples and of removing all strain on the lenses created by the bending of the temples.
