BINOOULAR-LOOP.

Specification of Letters Patent.

Patented July 23, 1912.

Application filed February 17, 1912. Serial No. 678,324.

To all whom it may concern Be it known that I, CHARLES HENRY Pix- LEY, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Binocular-Loop, of which the following is a specification.

Articles which are designed to hold magnifiers in suitable position for use before the eyes are commonly known to the trade and to the users of said articles as loops, and, as is well known, in order to secure a proper blending of each magnified image without undue stress upon the muscles of the eyes, binocular magnifiers must be located a suitable distance apart and must also be set at a proper angle to one another or more properly to the eyes of the wearer.

My invention has relation to the provision of extremely simple and effective means in binocular loops or magnifiers for suitably adjusting both the distance apart and the angle of the magnifiers.

I have attained the above objects by means 01 the structure illustrated in the accompanying drawing, in which Figure 1 is a perspective of the frame of a binocular loop embodying my invention, and Fig. 2 is a section through the means I provide for frictionally maintaining the desired adjustment when the same has been secured.

Similar reference characters refer to similar portions throughout the several views.

The frame comprises a bridge 1, adapted to fit and rest upon the bridge of the nose. To the ends of the bridge are secured the right angled pieces, 1 which drop downwardly and then extend outwardly to the side of the face in a position which will not cross or interfere with the field of vision. To the outer ends of the pieces, 1, are secured by pivots, 1 temples, 1 which maintain the frame in position upon the face. To the portions of the pieces, 1 which extend downward from the bridge are secured the forwardly extending flexible pieces, 2, in the central portions of which are pro vided the slots, 2, and upon their forward ends, 2, are secured laterally extending lens cells or rims, 3, into which may be set either temporarily or permanently, the desired magnifiers (not shown).

' For the purpose of adjusting the distance between the magnifiers, and, at the same time, giving'them the proper angularity, I provide a rod, 4, to extend between the flexible pieces, 2, which is of suflicient length so that when the rod is at the ends of the slots, 2 farthest from the face, the pieces, 2, will converge slightly toward their outer ends, but will hold the lens cells as far apart as they will be required in actual use.

It will be seen that by reason of the convergence of the pieces, 2, the lens cells will have a slight angularity to each other. The ends of the rod, 4, are bored and tapped at 4, and headed bolts, 5 are screwed therein through the slots, 2. When the rod, 4, is drawn toward the face it will force the outer ends of the pieces, 2, nearer together thereby providing means for adjusting the separation of the magnifiers to suit the wearer by the extremely simple operation of moving the rod, 4, backward and forward, toward and away from the face.

To maintain the rod, 4, in the desired position, I have provided the slightly dished spring or friction washers, 6, and 6*, which have provided in their centers openings, 6", for the passage of the bolt, 5,and which are placed upon either side of the piece, 2, as clearly shown in Fig. 2.

From the above description, takenin connection with the drawings, it will be seen that my loop is of extreme simplicity both in structure and adjustment which is of great advantage both to the manufacturer and user, while at the same time nothing has been omitted which will contribute to its practicability.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A binocular loop comprising a bridge, brackets extending outwardly therefrom out of the field of vision of the eyes, temples pivoted to the outer ends of said brackets, flexible arms extending forwardly from the inner ends of said brackets, lens cells or frames extending laterally from the forward ends of said flexible arms, longitudinal slots in said arms, a rod extending between said slots adapted to hold the arms so as to slightly converge at their forward ends when said rod is at the forward end of said slots, and friction 'plates upon said rod upon each side of said arms for holding said rod in the desired position in said slots.

2. A binocular loop comprlsing a bridge,

brackets extending therefrom, temples pivoted to the outer ends of said brackets, flexible arms extending forwardly from said brackets, lens cells or frames extending from said flexible arms, slots in said arms, and a rod extending between said slots adapted to hold the arms so as to slightly converge at their forward ends When said rod is at the forward end of said slots.

3. A binocular loop comprising a bridge, brackets extending therefrom, temples pivoted to the outer ends of said brackets, flexible arms extending forwardly from said brackets, lens cells or frames extending from said flexible arms, slots in said arms, a rod extending between said slots adapted to hold the arms so as to slightly converge at their forward ends When said rod is at the for- Ward end of said slots, and means forfrictionally holding said rod in the desired longitudinal position in said slots.

In testimony whereof I afiix my signature in the presence of tWo Witnesses.
