To all'whom it may concern: quires considerable time and is expensive. Be it known that I, JOHN J. Hansen, In order. to reduce the operations and to Rochester, in the county of Monroe and State. provide a device which may be manufactured of New York, have invented certain new and and assembled at slight cost, I form the useful Improvements in MountingsforReadopposite or opposing edges of the lens of ing Lenses; and I do hereby declare the folsubstantially plane surfaces and provide lowing to be a full, clear, and exact descripthem with grooves or keyways, and provide tion of the same, reference being had to corresponding grooves or keyways in the the accompanying drawings, forming a part adjacent sides of the frame adapted, when 10 of this specification, and to the reference the parts are assembled, to register with numerals marked thereon. those in the lens and secure the parts from y present invention relates to a device movement by key pieces or looking pins, for holding or supporting lenses, and parthe sides of which enter the corresponding ticularly to provide a magnifying reading and adjacent grooves in both the lens and 15 glass to be held in the users hand which frame; shall be simple in construction, readily as- In the embodiment shown in the drawing sembled, and with the parts being arranged A represents a lens which, when viewed in relatively and so balanced that it may be plan, is preferably substantially rectangumaintained by the use'rin proper reading polar and oblong, and its opposite longitudinal 20 sition with aminimum of fatigue.

The grinding and ing between the parts and they are not liable 55 polishing of the edge of a circular lens reto become displaced in use.

The lens A may be a section of a sphere or may be lano-convex, double convex, or cylindrical, or of other form, but whatever the conformation of its refracting surfaces, it is preferably of oblong or of substantially rectangular oblong form, and the handle is connected between the center of the lower side of the frame and one of the lower corners thereof, and projects at an angle to the lower edge beyond the narrower side of the frame.

This construction and arrangement of the parts provides a laterally elongated lens opening covering a relatively wide field such as a column of printed matter (particularly advantageous when a long cylindrical lens is employed) and the handle projects at such an angle from the plane of the opening, that the device may be held by the user without unnecessary fatigue, his hand being located at the side of the printed matter in a natural and comfortable position.

By attaching such a handle intermediate the ends of the frame the device is also balanced and is not liable to turn in the hand of the user even when a thick, heavy lens is used.

The form of connection between the lens 'and frame embodying the longitudinally eX- tending grooves formed therein and the readily applied keys or locking wires, is advantageous in that the lenses may be molded without being ground and polished at their edges and the grooves formed and the parts readily assembled by unskilled operators thus cheapening the product, and this feature can be readily employed in securing lenses such as stereoscopic lenses or prisms in their frames, or mirrors if desired.

\Vhile I prefer to employ a single piece holding frame for the lens the feature of securing the lens from lateral movement by means of the grooves and keys is advantageous in constructions in. which the cooperating and opposing sides of the frame are movable relatively to the lens and secured in position by other means.

I claim aS my invention: a

1. A holder for glass articles such as lenses, comprising a suitable frame embracing the edge of the article and provided with grooves in its inner opposed sides, in combination wit-h the article, such as a lens, having substantially straight edges in contact with the grooved sides of the frame, provided with grooves therein open toward the outer side only and arranged adjacent the grooves in the frame, and the keys or rods arranged in both the grooves in the article and in the frame.

2. A holder 'for glass articles such as lenses, comprising a suitable frame having relatively movable opposed sides embracing the edges of the article and provided with grooves therein, in combination with the article having substantially straight edges in contact with the grooved sides of the frame and provided with corresponding and opposin grooves therein open toward the outer sic es only, and the keys or rods arranged in the grooves in the article and in the frame.

3. The combination with a lens frame comprising a strip of materialhaving its ends detachably connected and its inner opposed sides provided with grooves, of a lens fitted within the frame having grooves in its edges open toward the outer sides only and arranged opposite the grooves in the frame and the separate and detachable securing keys arranged in the grooves in the lens and frame to prevent relative movement of the parts.

t. The combination with a substantially rectangular lens frame having relatively movable sides provided with grooves in their inner surfaces, of a lens fitted within said frame and .having substantially straightsides provided with grooves corresponding to those in the frame and open toward the outer sides only and the lens holding keys or rods arranged between the frame and lens the sides of said keys extending into the grooves in both parts.

5. A reading glass comprising a lens frame having an elongated opening therein, an elongated lens arranged in said opening and a supporting handle rigidly connected to the longer side of the frame between its center and the narrow side thereof and extending at an angle to said longer side and beyond the narrow side of the frame.

6. A reading glass comprising a substantially rectangular elongated frame, a substantially rectangular elongated lens mounted -therein and a substantially straight handle rigidly connected to the longer side of the frame at a point between the center thereof and the narrow side and extending laterally at an angle to said longer side and beyond the narrow side of the frame;
