SPECIFIC TIGN forming part Of Letters Patent No. 673,786. dated May '7, 1901.
Application filed June 7,1900.
To all 11/77/0177, it 717/07 concern:
Be it known that I, JOHN B. RIcKnTTs, of Kansas City, in the county of Jackson and State of Missouri, have invented a new and valuable Improvement in Shaded Eyeglasses; and I do hereby declare that the followingis a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon.
Figure 1 of the drawings is a representation of a vertical front view of myinvention. Fig. 2 is a vertical side representation of same. Fig. 3 is a representation of a threequarter view of same. Fig. 4 is a representation of a sectional view of same. Fig. 5 is a representation of mounting.
This invention has relation to shades that will soften or entirely shut off the upper and side rays of light from the eyes of the wearer, with lenses attached. By their use the wearer is aiforded perfect concentration of vision on the work in hand, and the strain on the muscles of the iris is reduced to the minimum, as the eyes have only to adjust themselves to the rays reflected from the object under consideration, be it book, paper, or other article, thus relieving the eyes from the confusing variety of rays from surrounding objects.
In the accompanying drawings, a, represents the spring, of gold, steel, or any other suitable metal. It-describes compound curves, as shown in Figs. 1, 2, and 3. It curves out at the top, as shown in Figs. 2 and 3, so as not to interfere with the brow of the wearer, and it is riveted or screwed on obliquely across the inner ends of the shad as b b, as shown in Figs. 1, 2, and 3. This spring possesses qualities of adjustment which make it of special value to this inventionas, forinstance,when it becomes necessary to set the outer points of the shades I) Z) farther apart. Take the end of the spring a and the end of the shade b where they are joined together between the thumb and forefinger and roll them together. By this means the points of the shades may be set outward as far as may be desired to fit any face. To set the points of the shades closer together, simply reverse the operation Serial No. 19,484. (No model.)
as above described. To set the outer points of the shades b I) up or down, take the center of the spring (it between the thumb and forefinger of the left hand. Then take the end of the spring a and the end of the shade b where they are joined between the thumb and forefinger of the right hand and by twisting in the proper direction the outer end of the shade b may be set either up or down, as may be desired, so as to make the upper lines of the shades b b conform to the arch over the eyes of the wearer.
b I) represent the shades, which may be made of hard rubber or any other material which will soften or entirely shut off the upper and side rays of light from the eyes of the wearer. The upper line of the shades b 1) describes a straight line from the outer point, where it is rounded to form a finish, to the inner end, which is also shaped to fit the curve where the base of the nose joins the arch over the eyes. The shades b b may vary in length. Itisintended that the inner ends of the shades b I) rest on the sides of the nose and conform to the arch over the eyes, with the outer points resting on the cheek-bones.
Where the shadesb b are bent to a form to give the desired curvature, with the upper or straight line of the shade kept on a line parallel to the form, they will conform to the arch over the eyes and flare out at the bottom just right to give the desired range of vision. The shades b b may also vary in width according to the uses to which they maybe put; but the principle remains the same.
01 represents a mounting for attaching the lenses 0 c to the shades b b. They may be made from any suitable metal. They are attached to the under side of the shades b b by a screw or rivet. There may be one or more of them to each lens. The lips are turned up on the dotted lines to receive the lens 0, which is attached by ascrew or rivet. The lenses 0 0 may have rims of metal or any other suitable material, or they may be plain, with holes drilled through them for receiving the screw or rivet, by which they are held in position by the mounting d, as shown in Fig. 4.
I am aware that prior to my invention shaded spectacles have been made with arched shields for shutting off the upper rays of light. I therefore do notclaim such a combination broadly; but
What I do claim as my invention, and desire to secure by Letters Patent, is-
A combined shade and eyeglass consisting of two curved shades of suitable material, a
bow-spring having compound curves and joining the shades at their inner ends, lenses, and means for attaching the latter to the [0 Shades whereby they shall be located before the eyes, substantially as described.
