tween said screw and the finger 26; and

To all whom it many concern..-

Be it known that I, GEORGE S. Row, a

citizen of the United States, residing at frame, and properly easily adjusted thereon, the construction being such that the arts will have a sufiicient amount of flexiility to prevent accidental cracking of the lens and also such that the screw cannot become readily separated from the frame.

The accompanying drawings illustrate my invention.

Figure 1 is an elevation about double size ofbne-half of an eye glass structure fitted with my improvement; Fig. 2 an axial section on a very enlarged scale, and Figs. 3

and 4 diagrams illustrating the manner of adjustment of the lens.

The fitting comprises a main body or post 10 having the usual box 11 for the reception of the nose piece holder 12 and a spring 13. Projecting from shank 10 is a clamping ear '15adapted to extend over a portion of the surface of the lens 16 and this ear 15' is provided with a threaded opening 17 through which may be passed the threaded portion 18 of the holdlng screw 19, said holding screw, immediately beneath the head, being ensmalled at 21 to 'a diameter slightly less than the smallest internal diameter of threads, 17, this ensmalled portion having an axial extent sufficient to extend through car 15. The lens 16 is provided with the usual perforation 22 through which the threaded portion 18 of screw 19 may readily pass, and at its free end the thread portion 18 of screw 19 is adapted to rece ve a cup-shaped nut 23 adapted to bear upon the opposite face of lens 16. At that portion .of its edge immediately adjacent "post 10 lens 16 is provided with a shallow notch 25 which is adapted to receive the free end of a finger 26 which is; preferably formed integral with post 10 opposite the car 15 and bent toward said 'ear 15, as clearlyv shown in Fig. 2, the arrangement being such that the finger 26 may be readily bentntoward or from the axis of screw 19,

so that the lens may be crowded tightly bemay be also bent to either side of the axis of the fitting so as to thus swing the lens Zpon screw 18 as a pivot and thus adjust the ngle of the lens relative to the fitting, as clearly illustrated in Figs. 3 and 4..

In operation the screw 19 has its threaded portion passed through the threaded perforation 17 of ear 15 until the ensmalled portion 21 lies within the threaded opening 17 whereupon screw 19 may be turned in either direction without producing any axial movement of the screw. This construction renders it impossible for the screw 19 to be accidentally lost yet it is always possible by exerting a slight axial pressure upon the threaded .en'd'of the screw to cause an engagement of the threads 18 with the threads 17 and thus the screw. Finger 26 is then bent toward or from the .axis'of screw 19 to just accommodate that portion of the lens which lies between the perforation 22 and the bottom of notch 25 and the lens is then forced into permit a total withdrawal of.

place so as to produce aslight backward pin 18 as a pivot. When the proper adjust.

ment has been attained the nut 23 is brought .down upon the lens as already described.

I claim as my invention:

l. A rimless lens fitting comprising a main post, a projecting lens-receiving ear, means for fastening a lens to said ear, and a transversely adjustable projecting finger carried by the main post and adapted to enter a notch formed in the adjacent edge of the lens, the free end of said finger being transversely shiftable in the line of the adjacentedge of the lens. w 2. A 'rimless lens fittingv comprlsing a main post, a projecting lens-receiving ear, means for fastening-a lens to said ear, and a transversely adjustable projecting portion carried j by the main post and adapted to entera notch formed in the adjacent edge of the lens, said adjustable projecting portion being in the form of a bendable arm extending transversely shiftable-in'the line of the adtransversely across the edge of the lens and tate loosely withinthe threaded opening of jacent edge of the lens. t

3. A rlmless lens fitting comprising a main post having a projecting lens-receiving ear'having a threaded opening, a clainping screw threaded through said threaded opening and having an ensmalled portion immediately beneath its head adapted to rotate loosely within the threaded opening of the lens receiving ear, and a nut carried upon the threaded end of said screw. 1

4. A rimless lens fitting comprising a main post'havi'ng a projecting lens-receiving ear having a threaded opening, a clamping screw threaded through-said threaded openin and having an ensmalled ortion immediately beneath its head adapte to rothe lens-receiving ear, a nut carried upon the threaded end of said screw, and a bendable finger carried by the post and having its free end lying substantially parallel with said screw and adapted to lie within anotch formed in the edge of the lens, said-tree end being transversely shiftable in the line of the adjacent edge of the lens.

In witness whereof,' I have hereunto set my hand and sealat Indianalpolis lndiana, this 28th day of September,
