orrrrmmc MOUNTING:

Application filed April 5, 1928. Serial Ito. 90,858.

This invention relates to an improvement in ophthalmic mountings and has particular reference to an improved adjustable bridge and arm construction for the same.

The principal object of this invention is to provide adjustable means for the lens and guard connections of an ophthalmic mountmg whereby the lenses may be adjusted to be positioned before the eyes and whereby the guards may be independently adjusted for their proper relation with the nose ofthe wearer.

Other objects of the invention will become apparent from the following description taken in connection with the accompanying drawings, and it will be apparent that changes and modifications in the arrangement and construction of the parts may be made without departing from the spirit of the invention as expressed in the accompanying claims, the preferred form only of the lnvention having ,been shown by way of illustration. I, therefore, do not wishto be limited to the exact details of construction and arrangement of parts shown.

Referring. to the drawings in which simi lar characters of reference denote corresponding parts throughout:

Figure 1 is a perspective View of the bridge and guard, construction and its at,-

tachment to' the lens connecting means;

Figure 2'is a rear elevation of Figure 1; Figure 3 is a side elevation of Figure. 2; Figure 4 is a partial plan view of a modified form of the invention showing a dif-' ferent arrangement of the loops connecting the lens attaching .means and the guard means, respectively.

Referring to the drawings, a pair of lens connecting clips 1 are connected by a bridge member 2 havingat each end a forwardly extending loo'p portion 3 and a downwardly I extending portion 4 which is attached to the lens holding clip 1;. also on the respective ends of the bridge 2 is a second'loop por-- tion 5 which extends rearwardly and downwardly to. a forwardly extendingloop portion 6 and aforwardly extending arm 7 to which is secured the nose guard 8.

In Figure 4 I have shown a modification in which theadjustable loops 6 and 3 are made in an S shape-having one end attached to the lens clip 1 and the other end attached to the nose guard 8 and the bridge 2 secured at the point .9. The adjustments of this modification are practically the same as those of the construction shown in Figure 1.

The method of operation is as follows: The lens clips 1 may be adjusted in and out and up or down by bending the loop portion 3. In this way the distance between 'the lens clips 1 may be regulated as well-as its position vertically, and also the lens cl ps 1 may be adjusted to a nearer or farther approach to the guard 8 by bending the loop portion 3. The nose guards 8 may be adjusted in or out, up or down, or angled .by bending the arm 5 and the loop portion 6. This allows the bridge to be positioned on the nose up or down, in or out, or angled. by the bending of the arm 5 and the loop 6. The guard 8 may also be approached towards or moved away from the lens clips 1 by adjustment of the said arm 5 and loop 6.

The adjustments of the loop 3 and the loop 6 may be made independently of each other. Therefore, the lens clips 1, maybe adjusted without disturbing the adjustment of the guards 8 and the guards 8 may be adjusted without disturbing the adjustment of the lens clips 1. This construction,'therefore, allows a double adjustment to adjust the guards to the nose on one hand and the lens clips to the eyes or face on the other .hand, whereby the'mounting can be perfectly adjusted to all'the facial requirements of the wearer.

It has been found in practice that there are many variations in the facial characteristics of people, and it is, therefore, very difficult to adjust a mounting to givethe proper pupillary distance, the proper height, the proper angle of the guards on'the nose,- and the proper adjustment in or out or sidewise.

From the foregoing it will be seen that I have provided simple, eflicient and inexpensive means for carrying out the yariousadjustments required in th fitting of an ophthalmic mounting, well adapted to carry out all the objects of the invention.

- Having described myinvention, I- claim: 1. In a device of the character described in combination with means for holding a pair of lenses, 9. bridge member connectin the lens holding means comprising a centra bridge portion and bifurcated terminal loop 5 portions, one bifurcation extending rearwardly and then forwardly and the other.

bifurcation extending forwardly downwardl{ and rearwardly, a nose guar secured to t e forwardly extending rtion ofthe first 1o bifurcation and a lens hol ing means secured to the rearwardly extending portion of the other bifurcation.
