PH HAL MOUNTING- Specification of Letters Patent.

Patented May 310, 1191c.

Application filed April 3, 1914. Serial No. 829,244.

To all whom it may concern:

Be it known that I, HARRY H. STYLL, a citizen of the United States, residing at Southbridge, in the county of Worcester and State of Massachusetts, have invented certain 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 a mounting in which the lenses are held in fixed position relative to each other and in which means are employed for securing the mounting in position on the face without disturbing the relative position of the lenses.

The leading object of my invention is the provision of a practical and efiicient mounting in which the lenses are rigidly connected and are retained on the face by resiliently supported gripping members which are entirely automatic in operation.

Another object of my invention is the provision of an improved type of guard so shaped as to facilitate the automatic operation of the mounting as it is applied to the nose and which will securely engage the nose to retain the mounting in correct position thereon.

Among other objects of this invention are the provision of a mounting of the eyeglass type which may be placed on the face or re moved therefrom without any manual shifting of the guards, which will insure correct positioning of the mounting on the nose and which will embody certain novel details of construction and principles of operation substantially as hereinafter described.

Further objects and advantages of my improved ophthalmic mounting should be readily apparent by reference to the follow ing specification taken in connection with the accompanying drawings, and it will be understood that I may make any modifications in the specific details of construction shown and described within thescope of the appended claims without departing from or exceeding the spirit of my invention.

Figure I represents a fragmentary view of a mounting embodying one form of my invention. Fig. II represents a similar view illustrating the use of a different form of bridge andguard attachment. Fig. III illustrates another method of attaching this form of my guard. Fig. IV illustrates another construction of retaining members. Fig.

V represents another form thereof. Fig. VI represents another manner of attaching, the construction being varied to correspond with the manner in which the same is attached. Fig. VII represents a form in which the upper and lower guard members are separately attached. Fig. VIII illustrates a form similar to Fig. V. Fig. IX represents a construction similar to Fig. IV but without handles. Fig. X represents another slight variation of my invention. Fig. XI repre-. sents another form thereof. Fig. XII represents a sectional view of one of my improved guards on the line XIIfiXII of Fig. VI.

In the drawings, in which similar characters of reference are employed to denote corresponding parts throughout the several views, the numeral 1 denotes the lens attachments having mounted therein the lenses 2, said attachments being connected by means of a bridge 3 which may be of either the C or saddle type, as desired, and which is preferably rigidly constructed, although it will be understood that it is capable of a certain degree of adjustment and may also, if desired, have slight resiliency, it being the primary purpose of this connecting member, however, to retain the lenses in certain predetermined position relative to each other, the bridge being therefore hereinafter referred to as a rigid bridge on account of the fact that the lenses are not shifted to operate the guards, as is the case with what is ordinarily termed a spring bridge.

In that form of my invention illustrated in Fig. I, I have shown attached to the bridge by means of the screw 4 the guard arm 5 bearing the lower weight supporting member 6, having curving upward therebehind the resilient arm 7 bearing-at its upper end the pad 8.

Fig. II illustrates the same type of construction with the exception that it is used in conjunction with a saddle instead of a C bridge, and the .arm 5 is secured directly to the bridge as by soldering inplace of being connected thereto by the screw.

In Fig. III the arm5 is made of sufficient length to span the bridge in a U-shaped portion and be clamped thereon by means of a screw.

In Fig. IV, I have illustrated another forinof one piece construction in which the arm 5 carries the guard 6 at the rear and has the resilient arm 7v formed with one rear, thus attaining some additional resilitaking hold of the lenses.

ency, while to facilitate'handling of the mounting there is carried by the portion5 a handle 9 which may be readily grasped by the fingers tohold the mounting without In Fig. V,I have shown the double looped arm 7, the difference being that both the lower member 6"and the upper member 8 are carried by said arm, the upper member 8, however, being connected to the remain der of the guard by means of an additional resilient loop 10. i V p In Fig. VI, I have shown the bridge as continued beyond its point of attachmentto the lenses, the lower guard member being formed integral with the bridge,the upper member being supported by the looped arm 7 which is suitably secured to the bridge or lens attachment, as desired, in the present instance it being shown as connected with the lens attachment.

F ig.-VII illustrates a' similar construction in which the lower guard member, however, in place of being integral is secured to the saddle bridge, the arm 7 in this instance also being carried by the strap portion of the mounting; 7 r

Fig. VIII illustrates a construction simi- 'lar in general appearance to that of Fig. V, in thatthe lower member is earned by the looped arm 7 the arm in this instance,

however,'having only the rearward instead of both forward and rearward loops, while the padis supported" by the upper resilient the gripping member 8 is formed integral with the said resilient arm in place of being pivoted thereto, the operation of the two constructions being identical.

In Fig. X, I have shown the resilient arm as integral 'withthe bridge, being reversely bent and extending upward in the lower bearing portion 6 and the upper gripping -portion 8', which' is preferably attached to the main 'arm for 'wabbling movement, a thin resilient portion 10 connecting the bearing member 6 'and'gripping member 8. In Fig. XI, I; have shown the arm 7 as "looped parallel with in place of at right.

' angles to the plane of the lens.

In all 'of the forms of my inventionthe operationis substantially the same, in that V the mounting'is simply slipped onto the'nose without any manual operation of the guards.

Previous to my invention there have been two general types of eyeglasses which have or by tilting upward or outward of the been commercially employed, one in which the guards were secured for movement by the lenses, either by laterally shifting of the lenses, as in the case of a bar spring eyeglass,

lenses, in the case of various spring bridge types of eyeglasses; the other in which the lenses were substantially rigidly connected and in which guards were mounted for pivotal movement, being preferably spring 7: actuated in one direction and manually operated in the other, and commonly known as finger piece mountings. Both of these forms embody a number of disadvantages. With the lens controlled type of mounting there is always danger of getting the lenses in other than correct position on the face, since if the mounting is not placed exactly where it was originally fitted, or should any of the parts become loose the lenses will stand with their axes at an incorrect angle,

which is very serious, or will incline either outwardly or inwardly and thus produce prismatic effects, in addition to which there is always the liability of the lenses being decentered on account of being too high or too low on the face. On the other hand, with the finger piece type of mounting the moving parts in frictional engagement with each other show a certain tendency to wear. Dependence must be placed on a relatively small spring,v space must be provided for the pivot and moving lever, thus requiring a wider distance between the lenses than is necessitated by the facial characteristics of the wearer, while the symmetry of appearance of the mounting is also liable to be impaired by the presence of the lever and acthe bridge or lenses, or the handles 9, in

these forms in which handles are provided, and press the mounting inward on the nose 1 0 with a slight rolling movement, this pressure being sufiicient to readily flex the spring arm 7 or 7 and allow the mounting to automatically fit onto the nose, the said resilientor spring arms forcing the gripping members into such engagement with the nose as to retain the mounting in position.

In this connection I would call particular attention to the sectional view Fig. XII,

from which it will be noted that my upper or gripping member 8 is of substantially concavo-convex form, that is to say, the rear portion thereof is curled outwardly and this shape of gripping member is of extreme importance in connection with my improved mounting, since the said curved portion 11 will ride on the side of the nose much after the manner of a runner, and will readily and easily flex and force backward the spring supporting arm therefor to allow the nose to separate the two grips until the mounting has been placed in correct position without in any way abrading or injuring the skin. At the same time the straight front engaging portion 12 of the pad is so positioned that the forward edge thereof will bite into the loose flesh at the top of the nose of the wearer and will securely retain the mounting in position until it is desired to remove the same, when the upward rolling movement will permit of the ready withdrawal of the mounting from the face. To facilitate this withdrawing movement, if desired the ends of the pad may also be somewhat rounded, as indicated in the various views.

It is further to be noted that in a large number of the forms of my invention illustrated, I have made use of a rigid, or substantially rigid, but adjustable lower weight supporting portion 6 adapted to rest on the bony side structure of the nose, and to support the weight of the mounting, this being properly adjusted to correctly fit on one point of the nose and to at all times insure correct positioning of the mounting thereon. When this type of construction is used the lower members will support the mounting and insure correct positioning of the same before the eyes, the function of the upper members being then merely to grip the loose flesh and prevent falling of the mounting 05 the face, to accomplish this result but relatively little spring pressure being required.

While as mentioned in the foregoing description, the arms 7 or 7 are resilient, it is to be understood that the character of material from which they are formed is such as to have ample resilience for the desired purpose, and at the same time be sufliciently pliable so that the same may be adjusted as may prove necessary in fitting the mounting to the individual requirements of the wearer.

I claim 1; In an eyeglass of the type retained in position on the face by gripping engagement of the guards with the nose, the combination with a bridge and lens clips connecting the lenses, of means for retaining the mounting in position on the face, comprising a lower substantially fixed nose engaging positioning member, and an upper gripping member, said upper gripping member being mounted on a looped resllient arm having its outer end held in substantially rigid nonpivoted position, and said upper bearing member having a substantially straight inwardly disposed front edge for biting into the flesh at the side of the nose of the wearer and having an outwardly flaring or rounded rear edge to facilitate pressing of the mounting onto the nose, substantially as and for the purpose described.

2. In an eyeglass mounting of the character described, the combination with a rigid bridging member connecting the lenses, said member being of the saddle type, of a guard depending from the arch of the bridge to provide a nose engaging rest for positioning the mounting on the face, an arm curving forwardly from the terminus of the bridge, and thence rearwardly in a resilient spring arm reversely inwardly bent and having loosely mounted thereon a member for gripping the nose to secure the mounting in place thereon.

3. In an eyeglass mounting of the character described, the combination with a rigid bridging member connecting the lenses, said member being of the saddle type, of a guard depending from the arch of the bridge to provide a nose engaging rest for positioning the mounting on the face, an arm curving forwardly from the terminus of the bridge, and thence rearwardly in a resilient spring arm reversely inwardly bent and having loosely mounted thereon a member for gripping the nose to secure the mounting in place thereon, said gripping member having a rounded rear edge to facilitate separation of the two gripping members by pressing of the mounting toward the nose, and having a straight inwardly disposed front edge adapted to raise and grip the loose skin on the upper portion of the nose to prevent slipping of the mounting.

In testimony whereof I aflix my signature in presence of two witnesses.
